{First embodiment}
The differential communication connector support structure and the differential communication connector-attached wire harness according to the first embodiment will be described below. FIG. 1 is a schematic view showing a wire harness 20 with a connector for differential communication.

  The differential communication connector-attached wire harness 20 includes a wire harness 22 and a differential communication connector support structure 50.

  The wire harness 22 has a configuration in which a plurality of electric wires 23 are bundled. In addition, in each figure, the electric wire bundle in which the some electric wire 23 was bundled is drawn, and the one part electric wire 23 is drawn in FIG.

  More specifically, the wire harness 22 has a configuration in which a plurality of electric wires 23 are bundled while being branched according to an arrangement route in a vehicle or the like. The plurality of electric wires 23 are bound by a binding band, an adhesive tape, or the like. A connector 25 is attached to the end of the electric wire 23 at each end of the wire harness 22.

  In a state where the wire harness 22 is assembled to a vehicle or the like, each connector 25 is connected to an electrical component 28 (a part of which is shown in FIG. 1). Thereby, the wire harness 22 is used as a wiring component for connecting the electrical components 28 mounted on the vehicle or the like.

  The wire harness 22 is provided with a plurality of differential communication lines 40, and the differential communication lines 40 are connected to each other in the middle of the path of the wire harness 22.

  Here, the wire harness 22 is provided with two differential communication lines 40. A connector 42 is provided at one end of each differential communication line 40. Each differential communication line 40 is connected to the electrical component 28 having a communication function through the connector 42. At the other end of each differential communication line 40, differential communication connectors 44 and 48 are provided. The differential communication connectors 44 and 48 are interconnectable connectors. Each differential communication line 40 is attached to the wire harness 22 via a binding member 27 such as a binding band or an adhesive tape along the path of the wire harness 22. The other end portions of the differential communication lines 40 face each other along the path of the wire harness 22, and the differential communication connectors 44 and 48 are connected to each other. As a result, the two differential communication lines 40 are connected to each other, and the electrical components 28 to which the connectors 42 are connected are connected to each other via the two differential communication lines 40.

  Here, differential communication is a communication method for transmitting a signal by a potential difference between two signal lines, and is adopted in a CAN (Controller Area Network) or the like. A communication device that performs differential communication is incorporated in the electrical component 28 to which the connectors 42 are connected. The differential communication line 40 includes a communication cable 41 including electric wires that are two signal lines, and connectors 42 and 44 (or 48) at both ends thereof. As the communication cable 41, one having a configuration in which two electric wires 40a and 40b are twisted and the outer periphery is covered with a covering portion is used (see FIG. 11).

  Normally, in the differential communication as described above, even if the same noise is added to the two signal lines, the noise is canceled when the potential difference between the two signal lines is taken. However, the inventor of the present application has noticed that the transmission characteristics may deteriorate when the differential communication line 40 is disposed along the wire harness 22. The inventor of the present application examined the cause, and realized that the cause is the support posture of the differential communication connectors 44 and 48 interconnected in the middle of the wire harness 22. That is, in the communication cable 41, since the two electric wires 40a and 40b are twisted and arranged along the wire harness 22, similar noise is applied to the two electric wires 40a and 40b. For this reason, the noise added to the two electric wires 40a and 40b is canceled. In contrast, the differential communication connectors 44 and 48 have two terminals corresponding to the two electric wires 40a and 40b, and the positional relationship between the two terminals and the wire harness 22 is uneven. The noise applied to the two terminals will be different. Then, it becomes difficult to cancel noise added to the two terminals in different modes. In particular, when the communication speed is increased, the above problem significantly affects.

  In view of the above knowledge, the present inventor has found that the following configuration may be adopted as a support structure for a differential communication connector in which a differential communication connector is attached to an attachment target component.

  2 is a schematic cross-sectional view taken along the line II-II in FIG. 1, FIG. 3 is a schematic side view showing a support structure 50 for a connector for differential communication, and FIG. It is the figure seen from a certain wire harness 22 side.

  The differential communication connector support structure 50 includes a differential communication connector 44 and a connector support portion 60.

  The differential communication connector 44 includes a connector housing 45, a first connector terminal 46, and a second connector terminal 47.

  The connector housing 45 is a member formed of resin or the like, and holds the first connector terminal 46 and the second connector terminal 47 in a parallel posture.

  More specifically, the connector housing 45 is formed in a rectangular parallelepiped shape. Here, the connector housing 45 is formed in a shape whose height dimension is larger than the width direction dimension, but may be a horizontally long shape whose width direction dimension is larger than the height dimension. A connection recess 45 a into which the mating connector 48 can be inserted is formed at one end of the connector housing 45. A cavity into which the first connector terminal 46 and the second connector terminal 47 can be inserted is formed in the connector housing 45 on the back side of the connection recess 45a.

  The 1st connector terminal 46 is a member formed by carrying out the press work etc. of the metal plate etc., and is formed in the shape where the other party connection part 46a and the electric wire connection part 46b were connected to linear form. The mating side connection part 46a is a part connected to a terminal on the mating connector 48 side. Here, the counterpart connection part 46a is formed in a tab-shaped or pin-shaped male terminal shape. The electric wire connecting portion 46b is a portion that is connected to the end of the electric wire 40a (or 40b) and is electrically connected to the core wire of the electric wire 40a (or 40b). The electric wire connection part 46b has, for example, a configuration including a core crimping part that is crimped to the core part exposed at the end of the electric wire 40a (or 40b) and a covering crimping part that is crimped to the covering part at the end of the electric wire 40a. is there.

  The 2nd connector terminal 47 is comprised similarly to the said 1st connector terminal 46, and is provided with the other party connection part 47a and the electric wire connection part 47b.

  The first connector terminal 46 and the second connector terminal 47 are inserted into the corresponding cavities from the rear side of the connector housing 45, for example. Then, in a state where the electric wire connection portions 46b and 47b are inserted and held in the cavity, the mating connection portions 46a and 46a protrude from the back side of the connection recess 45a toward the connection recess 45a. In this state, the first connector terminal 46 and the second connector terminal 47 are accommodated in the connector housing 45 in a parallel state with a gap therebetween. In the differential communication connector 44, the direction in which the first connector terminals 46 and the second connector terminals 47 are arranged is the width direction, and the direction perpendicular to the width direction and the extending direction of the accommodation hole 71 is the height direction. is there.

  When the differential communication connector 48 is connected to the differential communication connector 44, the two terminals in the counterpart differential communication connector 48 correspond to the first connector terminal 46 or the second connector. 2 is connected to the connector terminal 47. Thereby, the first connector terminal 46 or the second connector terminal 47 relays the differential signal between the two communication cables 41.

  In this example, the connection recess 45a is formed in the differential communication connector 44 fixed to the wire harness 22, and the other-side differential communication connector 48 is inserted and connected to the connection recess 45a. However, the connection recessed part may be formed in the reverse side. Moreover, although the 1st connector terminal 46 and the 2nd connector terminal 47 by the side of the connector 44 for differential communication fixed to the wire harness 22 demonstrated in the example which is a male terminal, these are formed in the shape of a cylindrical female terminal. It may be.

  The connector support 60 is a connector for differential communication with respect to the wire harness 22 so that the first connector terminal 46 and the second connector terminal 47 are in parallel with each other when viewed from the wire harness 22 that is an attachment target component. 44 is supported.

  Here, the positional relationship in which the first connector terminal 46 and the second connector terminal 47 are arranged in parallel is such that the first connector terminal 46 and the second connector terminal 47 are arranged in parallel with each other with a space therebetween. Refers to the positional relationship. For this reason, when the differential communication connector 44 supported by the connector support portion 60 is observed from the side where the wire harness 22 is present, the first connector terminal 46 and the second connector terminal 47 do not overlap and contact each other. Instead, they are observed to be separated from each other and parallel to each other.

  Here, since the attachment target component is the wire harness 22, assuming the wire harness 22, the connector support portion 60 includes the first connector terminal 46 and the second connector terminal 47 along the outer circumferential direction of the wire harness 22. It is preferable to support the connector for differential communication 44 so that they are lined up. That is, the first connector terminal 46 and the second connector terminal 47 accommodated in the connector housing 45 in parallel are supported so as to be aligned in parallel along the outer peripheral direction of the wire harness 22 of the wire harness 22. preferable.

  Preferably, in a state in which the connector for differential communication 44 is supported by the connector support portion 60, the first connector terminal 46 and the second connector terminal 47 are equal to the outer peripheral portion of the wire harness 22, which is a component to be attached. They are arranged in such a positional relationship as to be a distance.

  More specifically, the connector support portion 60 includes a binding band portion 62 that is wound around the wire harness 22 and fixed to the wire harness 22.

  The binding band portion 62 is a portion formed of resin or the like, and includes a band portion 63 and a band fixing portion 64.

  The band part 63 is a member extending in a band shape, and is a part wound around the wire harness 22. The base end portion of the band portion 63 is connected to the band fixing portion 64. A plurality of locking grooves are formed on the surface of the intermediate portion of the band portion 63.

  The band fixing part 64 is a rectangular tube-shaped part in which a band insertion hole is formed. In the insertion hole of the band fixing portion 64, locking claws that can be selectively locked in the plurality of locking grooves of the band portion 63 are formed.

  Then, with the band part 63 wound around the wire harness 22, the tip part of the band part 63 is inserted into the band insertion hole of the band fixing part 64. When the tip of the band part 63 is pulled strongly in this state, the locking claw is locked to the locking claw of the band part 63 while the band part 63 is fastened to the wire harness 22. Thereby, the binding band part 62 is wound around the wire harness 22 and is fixed to the wire harness 22. Thereby, the connector support part 60 is fixed to the wire harness 22.

  Further, the connector support portion 60 includes a connector holding portion 70 that holds the differential communication connector 44 in a fixed posture. In the present embodiment, the binding band portion 62 and the connector holding portion 70 are integrally formed by injecting softened resin into an injection mold.

  Here, the connector holding part 70 is formed in a cylindrical shape, more specifically, a rectangular tube shape. In the connector holding portion 70, a square hole-shaped accommodation hole 71 corresponding to the outer peripheral shape of the differential communication connector 44 is formed. The width dimension of the receiving hole 71 is the same as or larger than the width dimension of the differential communication connector 44 (slightly larger), and the height dimension of the receiving hole 71 is the same as the height dimension of the differential communication connector 44. It is formed large (slightly large). The differential communication connector 44 is accommodated in the accommodation hole 71 of the connector holding portion 70 in a state where the width direction of the differential communication connector 44 is matched with the width direction of the connector holding portion 70.

  A positioning portion 72 that abuts against the front end portion of the differential communication connector 44 projects from one end portion of the accommodation hole 71. At a position from the other end portion of the accommodation hole 71, a retaining portion 73 that abuts against the rear end portion of the differential communication connector 44 is projected. The retaining portion 73 is formed in a shape that gradually decreases in height toward the rear end side of the connector holding portion 70.

  When the connector for differential communication 44 is inserted into the accommodation hole 71 from the rear end side of the connector holding portion 70, the connector housing 45 comes into contact with the retaining portion 73 and is prevented from being detached by elastic deformation of the connector retaining portion 70 or the like. The part 73 escapes to the outer peripheral side. When the differential communication connector 44 is inserted into the accommodation hole 71 until the front end portion of the differential communication connector 44 contacts the positioning portion 72, the retaining portion 73 is restored to the original by the elastic restoring force of the connector holding portion 70. Returning to the position, it contacts the rear end of the connector 44 for differential communication. As a result, the differential communication connector 44 is held in the accommodation hole 71 in a state in which it is positioned between the positioning portion 72 and the retaining portion 73.

  The configuration in which the connector holding unit holds the differential communication connector 44 is not limited to the above example. For example, the connector holding unit may be configured to hold the differential communication connector 44 from both sides. Further, a fitting structure for keeping them in a combined state may be formed in one of the differential communication connector 44 and the connector holding portion.

  The connector holding part 70 and the band part 63 are integrally formed with the bottom part of the connector holding part 70 connected to a part of the outer peripheral side in the extending direction of the band part 63. For this reason, when the binding band part 62 is wound around the wire harness 22 and fixed, the width direction of the connector holding part 70 and the width direction of the differential communication connector 44 are determined by the connector holding part 70 in the outer peripheral part of the wire harness 22. It becomes the attitude | position extended along the tangent direction of the provided part. Thus, the first connector terminal 46 and the second connector terminal 47 accommodated in the differential communication connector 44 are supported so as to be in a positional relationship in parallel when viewed from the wire harness 22 side. More specifically, the first connector terminal 46 and the second connector terminal 47 are arranged so as to be arranged along the circumferential direction of the outer peripheral portion of the wire harness 22.

  The first connector terminal and the second connector terminal accommodated in the differential communication connector 48 are also connected to the wire harness 22 with respect to the differential communication connector 48 connected to the differential communication connector 44. The first connector terminal 46 and the second connector terminal 47 are disposed in the same positional relationship.

  According to the differential communication connector support structure 50 and the differential communication connector-attached wire harness 20 configured as described above, the first connector terminal 46 and the second connector terminal are viewed from the wire harness 22 side which is a mounting target component. 47 is supported so as to be in a parallel positional relationship, so that the positional relationship of the first connector terminal 46 and the second connector terminal 47 with respect to the wire harness 22 can be made as similar as possible. For this reason, even if noise is added to the first connector terminal 46 and the second connector terminal 47 in the differential communication connector 44, their noise states are as much as possible. For this reason, it becomes possible to cancel those noises as much as possible, and the deterioration of the transmission characteristics in the differential communication path can be suppressed.

  Further, since the first connector terminal 46 and the second connector terminal 47 are arranged along the outer circumferential direction of the wire harness 22, the first connector terminal 46 and the second connector terminal 47 are connected to the wire harness 22, in particular. The wire harness 22 is disposed in the same positional relationship as possible with respect to the core wire in the electric wire. As a result, when the differential communication connector 44 is disposed along the wire harness 22, it is possible to suppress deterioration of transmission characteristics in the differential communication path.

  Further, since the connector support portion 60 includes a binding band portion 62 that is wound around and fixed to the wire harness 22, the differential communication connector 44 can be easily fixed to the wire harness 22 using the binding band portion 62. .

  Further, since the connector holding portion 70 and the binding band portion 62 are integrally formed, the differential communication connector 44 held by the connector holding portion 70 can be easily supported with respect to the wire harness 22 in a fixed posture.

  Various modifications based on the first embodiment will be described.

  FIG. 5 is a schematic cross-sectional view showing the differential communication connector-equipped wire harness 120 and the differential communication connector support structure 150 according to the first modification.

  In the first modification, a connector holding portion 170 corresponding to the connector holding portion 70 and a binding band portion 162 corresponding to the binding band portion 62 are formed separately. That is, the connector holding part 170 and the binding band part 162 are members that are separately formed by resin or the like. The connector support part 60 includes a connector holding part 170 formed separately and a binding band part 162.

  A band through hole 171 into which the band part 63 of the binding band part 162 can be inserted is formed at the bottom of the connector holding part 170. The banding holes 171 are formed so as to extend in the width direction of the connector holding portion 170 and open to both sides of the connector holding portion 170.

  Then, in a state where the band portion 63 of the binding band portion 162 is inserted into the band through hole 171, the binding band portion 162 is wound around the wire harness 22 and fastened and fixed.

  In the above state, since the binding band portion 162 is wound around the wire harness 22 and fastened and fixed, the bottom portion of the connector holding portion 170 is pressed against the outer peripheral portion of the wire harness 22. For this reason, the connector holding part 170 is supported at a fixed position on the outer peripheral part of the wire harness 22.

  Since the band through-hole 171 of the connector holding part 170 has a posture along the extending direction of the band part 63 wound around the outer periphery of the wire harness 22, the first connector terminal 46 and the second connector terminal 47 are connected to the wire harness. 22 is held in a predetermined posture similar to that in the first embodiment. For this reason, it is possible to suppress deterioration of transmission characteristics in the differential communication path.

  Further, as the binding band portion 62, a general-purpose binding band used for fixing the binding of the wire harness 22 or the like can be used.

  FIG. 6 is a schematic cross-sectional view showing a differential communication connector-equipped wire harness 220 and a differential communication connector support structure 250 according to a second modification.

  In the second modification, the connector holding portion 70 is omitted.

  The connector support portion 460 includes a binding band portion 462 and a plurality of connector holding portions 470.

  The binding band portion 462 is the same portion as the binding band portion 62 described above. Each of the plurality of connector holding portions 470 is the same portion as the connector holding portion 70.

  The plurality of connector holding portions 470 are integrally formed with the binding band portion 462. The plurality of connector holding portions 470 are formed integrally with the outer peripheral portion of the binding band portion 462 while being separated from each other in the extending direction of the binding band portion 462.

  For this reason, when the binding band portion 462 is tightened and fixed to the wire harness 22, the plurality of connector holding portions 70 held by the plurality of connector holding portions 470 are mutually connected in the circumferential direction of the outer peripheral portion of the wire harness 22. Keeped away. For this reason, the influence of noise between the plurality of connectors for differential communication 44 is suppressed, and deterioration of transmission characteristics in the differential communication path can be suppressed.

  FIG. 10 is an explanatory view showing a wire harness 520 with a connector for differential communication according to a fifth modification, and FIG. 11 is a schematic sectional view showing a support structure 550 for the connector for differential communication.

  A plurality of differential communication connectors 44 are attached to the wire harness 22. In the fifth modification, a configuration in which a plurality of differential communication connectors 44 are attached in a predetermined path of the wire harness 22 will be described. .

  In the fifth modification, a plurality of (in this case, three) differential communication connectors 44 are attached to positions shifted in the predetermined path in a predetermined path in the wire harness 22. Therefore, a communication cable 41 extending to another differential communication connector 44 is disposed next to one differential communication connector 44. In the wire harness 520 with a connector for differential communication, a communication cable 41 including electric wires 40 a and 40 b is attached around the wire harness 22 at a position away from the connector for differential communication 44.

  Here, next to one differential communication connector 44, another communication cable 41 is attached to the wire harness 22 in a state of being separated from the differential communication connector 44.

  One differential communication connector 44 is supported around the wire harness 22 by the connector support portion 60 described in the first embodiment.

  A plurality (two in this case) of communication cables 41 are supported around the wire harness 22 at positions separated from one differential communication connector 44 in the circumferential direction of the outer peripheral portion of the wire harness 22. Here, a plurality (two in this case) of communication cables 41 are also supported around the wire harness 22 at positions separated from each other in the circumferential direction of the outer peripheral portion of the wire harness 22.

  The plurality (two in this case) of communication cables 41 are supported around the wire harness 22 by a binding member 560. Here, the binding member 560 is an adhesive tape, and a plurality of (here two) communication cables 41 are arranged along a predetermined position around the wire harness 22 and the wire harness 22 and the plurality (two here). ) Is wound around the communication cable 41. As the binding member 560, a binding band or the like may be used.

Deterioration can be suppressed.

  Of course, each differential communication connector 44 itself is held in a predetermined posture similar to that in the first embodiment, and also from this point, deterioration of transmission characteristics in the differential communication path is suppressed.

  The other differential communication connectors 44 are also supported around the wire harness 22 by a similar configuration so that the differential communication connector 44 and the communication cable 41 are positioned apart from each other.

  In the fifth modification, the example in which the holding structure of the differential communication connector has the configuration described in the first embodiment has been described. However, any of the first to third modifications may be adopted for each holding structure of the differential communication connector.

  FIG. 12 is an explanatory view showing a differential communication connector-equipped wire harness 620 and a differential communication connector support structure 650 according to a sixth modification, and FIG. 13 is a schematic view showing the differential communication connector support structure 650. FIG. 14 is an exploded view of the connector support portion 660, and FIG. 15 is a partially enlarged view of the connector support portion 660.

  That is, the wire harness 22 includes a plurality of branch portions 22b that branch from the main branch portion 22a from the same branch location. If the differential communication connector 44 is supported by any one of the plurality of branch portions 22b, the other branch portions 22b may be close to the differential communication connector 44 and cause noise.

  Therefore, here, the connector support portion 660 is attached to the plurality of branch portions 22b in a state where the branch form of the plurality of branch portions 22b in the wire harness 22 is kept constant.

  The connector support part 660 includes a first connector support part 662 and a second connector support part 666.

  The first connector support part 662 is a member integrally formed of resin or the like, and includes an annular part 663 and a connector holding part 664.

  The annular portion 663 is formed in a shape in which a part of the annular shape is opened. The inner diameter of the annular portion 663 is set to a size that can be disposed around the branch portion 22b to be attached. Then, by opening the opening of the annular portion 663, the branch portion 22b can be disposed in the annular portion 663.

  A pair of extending pieces 663a and 663b are provided so as to project outward from both end portions on the opening side of the annular portion 663. A retaining insertion portion 663c protrudes from one extension piece 663a toward the other extension piece 663b. The retaining insertion portion 663c is configured such that a plurality of disc spring-like annular locking portions 663d are formed at intervals in the axial direction of the shaft portion with respect to the shaft portion. The retaining insertion portions 663c can be inserted into retaining holes 667ah and 667bh, which will be described later, by elastically deforming each annular locking portion 663d so as to reduce the diameter, and are inserted into the retaining holes 667ah and 667bh. In the state, the annular locking portion 663d returns to its original shape and is locked to the retaining holes 667ah and 667bh. The other extending piece 663b is formed with a hole 663bh into which the retaining insertion portion 663c can be inserted.

  The connector holding portion 664 has the same configuration as the connector holding portion 70 described above, and is integrally formed on a part of the outer peripheral portion of the annular portion 663. For this reason, the differential communication connector 44 held by the connector holding portion 664 with the branch portion 22b disposed in the annular portion 663 is fixed to the wire harness 22 in the same manner as in the first embodiment. Is supported at the position and posture.

  The second connector support portion 666 is a member integrally formed of resin or the like, and includes an annular portion 667 and a connector holding portion 668.

  The annular portion 667 is formed in a shape in which a part of the annular shape is opened. The inner diameter of the annular portion 667 is set to a size that can be disposed around the branch portion 22b to be attached. Then, by opening the opening of the annular portion 667, the branch portion 22b can be disposed in the annular portion 667.

  A pair of extending pieces 667a and 667b are provided so as to project outward from both end portions on the opening side of the annular portion 667. The pair of extending pieces 667a and 667b is configured to be able to be disposed so as to overlap the pair of extending pieces 663a and 663b. Here, the pair of extending pieces 667a and 667b are disposed so as to overlap the inside of the pair of extending pieces 663a and 663b. The pair of extending pieces 667a and 667b are formed with retaining holes 667ah and 667bh into which the retaining insertion portion 663c can be inserted and retained.

  The connector holding portion 668 has the same configuration as the connector holding portion 70 described above, and is integrally formed on a part of the outer peripheral portion of the annular portion 667. Therefore, the differential communication connector 44 held by the connector holding portion 668 with the branch portion 22b disposed in the annular portion 667 is fixed with respect to the wire harness 22 as in the first embodiment. Is supported at the position and posture.

  Then, one branch portion 22b is disposed in the annular portion 663 of the first connector support portion 662, and the other branch portion 22b is disposed in the annular portion 667 of the second connector support portion 666. The extending pieces 667a and 667b are arranged so as to overlap the pair of extending pieces 663a and 663b, and the retaining insertion portion 663c is inserted into the retaining holes 667ah and 667bh to be retained. Note that the tip of the retaining insertion portion 663c is inserted into the hole 663bh.

  Thereby, the 1st connector support part 662 and the 2nd connector support part 666 are united, and the several branch part 22b is maintained by the fixed positional relationship which adjoins. In this state, the differential communication connector 44 is supported by the wire harness 22 at a position protruding to the side perpendicular to the plane including the trunk portion 22a and the plurality of branch portions 22b. For this reason, it is difficult for the adjacent branch portion 22b to approach the differential communication connector 44 supported by one branch portion 22b.

  According to this modification, when the differential communication connector 44 is attached to the plurality of branch portions 22b branched from the trunk portion 22a of the wire harness 22, the paths of the plurality of branch portions 22b with respect to the differential communication connector 44 are changed. It can be regulated to some extent. This makes it easy to maintain the differential communication connector 44 and the branch portion 22b in a certain positional relationship, and the transmission characteristics in the differential communication path are deteriorated due to the influence of the branch portion 22b adjacent to the differential communication connector 44. Can be suppressed.

  In addition, since the differential communication connector 44 is supported on each of the plurality (two in this case) of the branch portions 22b, the differential communication connector 44 supported at a position corresponding to each of the plurality of branch portions 22b. It is possible to maintain a fixed positional relationship between them and the branching portion 22b. Thereby, in each branch part 22b, deterioration of transmission characteristics due to the influence of the other branch part 22b and the influence of the connectors for differential communication 44 can be suppressed.

  However, the differential communication connector 44 may be supported only on one or a part of the plurality of branch portions 22b. In the example shown in FIG. 13, another communication cable 41 is bound and fixed to the branch portion 22b by a binding member 670 such as an adhesive tape (only a part is shown in FIG. 13). Thereby, the other communication cable 41 and the differential communication connector 44 can be kept in a certain positional relationship, and the deterioration of the transmission characteristics can be suppressed also from this point.

  In addition, any of the above-described modifications may be adopted as the configuration for supporting the differential communication connector 44 with respect to the branch portion 22b. Moreover, the example which maintains several branch part 22b in fixed positional relationship is not restricted to the said example, The structure using another protector etc. may be employ | adopted.

  In the seventh modification, the connector support portion 760 includes a panel fixing portion 762 that can be fixed to the metal panel member 721.

  More specifically, in the connector support portion 760, a panel fixing portion 762 is integrally formed at a component portion that faces the connector support portion 60 including the binding band portion 62 and the connector holding portion 70 described in the first embodiment. It has been configured. That is, the binding band portion 62 and the connector holding portion 70 and the panel fixing portion 762 are integrally formed of a resin or the like.

  The connector holding part 70 and the panel fixing part 762 are provided at positions facing the binding band part 62 with the central axis of the binding band part 62 interposed therebetween. For this reason, the connector for differential communication 44 is supported with respect to the metal panel member 721 so that the first connector terminal 46 and the second connector terminal 47 are arranged in parallel as viewed from the metal panel member 721. In other words, the wire harness 22 is supported on the metal panel member 721, and the differential communication connector 44 is supported on the opposite side of the metal panel member 721 with respect to the wire harness 22.

  The panel fixing portion 762 is configured to be insertable and fixed into an attachment hole 722 formed in the metal panel member 721. It is assumed that the metal panel member 721 is a part constituting a metal body of the vehicle. More specifically, the panel fixing portion 762 includes a base portion 763, a rod-like portion 764 that protrudes from the base portion 763, and a pair of locking pieces 765 that protrude from the base portion 763 toward the distal end side of the rod-like portion 764. . The pair of locking pieces 765 are formed in a shape that gradually turns outward in the middle from the base portion 763 toward the tip portion of the rod-like portion 764 and is bent toward the rod-like portion 764 side in the extending direction intermediate portion. ing.

  When the panel fixing portion 762 is inserted into the mounting hole 722, the outer peripheral portion of the distal end portion of the pair of locking pieces 765 contacts the peripheral edge portion of the mounting hole 722 and elastically deforms inward. When the outermost protruding portion of the pair of locking pieces 765 exceeds the mounting hole 722, the pair of locking pieces 765 returns to the original shape, and the outermost of the pair of locking pieces 765 protrudes outward. The portion is locked to the peripheral edge of the mounting hole 722 and is fixed so that the panel fixing portion 762 is inserted into the mounting hole 722.

  As the panel fixing portion, in addition to the above-described configuration, a configuration in which a pair of locking pieces protrudes outward from the rod-shaped distal end portion protruding from the base portion toward the rod-shaped proximal end side. The structure etc. which are used as a clamp for general vehicle fixation, such as the tree-shaped clamp structure in which the plate-shaped part was formed in multiple steps | paragraphs, are employable.

  According to this modification, the first connector terminal 46 and the second connector terminal 47 are disposed in the same positional relationship as possible with respect to the metal panel member 721. For this reason, in the case where the wire harness 22 supporting the differential communication connector 44 is disposed on the metal panel member 721, etc., it is possible to suppress the deterioration of the transmission characteristics of the differential communication path due to the influence of the metal panel member 721. .

  In the above embodiment, the connector holding portion 70 and the panel fixing portion 762 are integrally formed with the binding band portion 62. However, as described in the first and second modifications, the connector holding portion or A configuration in which the binding band is inserted into the band insertion hole formed in the connector housing, a configuration in which the binding band is inserted into the band insertion hole formed in the panel fixing portion, or the like may be employed.

  FIG. 17 is a schematic cross-sectional view showing a differential communication connector-equipped wire harness 820 and a differential communication connector support structure 850 according to an eighth modification.

  In the eighth modification, the connector support portion 860 includes a thick surrounding portion 872 that surrounds the differential communication connector 44 so as to separate the differential communication connector 44 from other components.

  Here, the connector support portion 860 is configured such that, in the connector support portion 60 described in the first embodiment, the connector holding portion 870 corresponding to the connector holding portion 70 is thickened.

  More specifically, a housing hole 71 is formed in the connector holding portion 870. The outer shape of the connector holding portion 870 is a shape surrounded by a curved surface that protrudes outward when the connector holding portion 870 is viewed from the front. The thickness dimension of the thick surrounding portion 872 between the inner peripheral surface of the accommodation hole 71 and the connector holding portion 870 is larger than the general thickness dimension required for holding the connector for differential communication 44, The size is set so as to suppress the deterioration of the transmission characteristics due to the members.

  According to this modification, the differential communication connector 44 can be separated from other components by the thick wall portion 872. As other parts, it is conceivable that the wire W is additionally attached to the wire harness 22 and a metal panel member constituting the metal body of the vehicle. As a result, the transmission characteristics in the differential communication path are hardly affected by other components, and deterioration of the transmission characteristics in the differential communication path can be suppressed.

{Second Embodiment}
The differential communication connector support structure 1050 according to the second embodiment will be described. FIG. 18 is a schematic front view showing a support structure 1050 for a connector for differential communication. In the description of the present embodiment, the same components as those described in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The differential communication connector support structure 1050 is a structure in which the differential communication connector 44 is attached to a metal panel member 1021 as a part to be attached. The differential communication connector support structure 1050 includes a differential communication connector 44 and a connector support portion 1060.

  The differential communication connector 44 is attached to the end of the communication cable 41 as described in the first embodiment. The communication cable 41 may be disposed along the wire harness or may not be disposed along the wire harness. A differential communication connector 48 as a connection destination is connected to the differential communication connector 44.

  When the differential communication connector 44 is attached to the metal panel member 1021 as a part to be attached, if the positional relationship between the two terminals and the metal panel member 1021 is not uniform, the noise applied to the two terminals will be different. Therefore, similarly to the above, it is difficult to cancel noise added to the two terminals in different modes, and transmission characteristics deteriorate. In particular, the metal panel member 1021 is a metal body or the like of a vehicle and is a part used as a ground, and thus easily affects transmission characteristics.

  Therefore, in the second embodiment, the following configuration is adopted as the support structure of the differential communication connector.

  That is, the connector support portion 1060 is different from the metal panel member 1021 so that the first connector terminal 46 and the second connector terminal 47 are in a parallel relationship when viewed from the metal panel member 1021 that is the attachment target component. The dynamic communication connector 44 is supported. Preferably, the connector support portion 1060 is for differential communication so that the first connector terminal 46 and the second connector terminal 47 are in parallel at a position that is equidistant from the main surface of the metal panel member 1021. The connector 44 is supported.

  More specifically, the connector support portion 1060 is a member integrally formed with a resin or the like, and includes a connector holding portion 1070 and a panel fixing portion 1062.

  A panel fixing portion 1062 is integrally formed at the bottom of the connector holding portion 1070.

  For this reason, when the panel fixing portion 1062 is inserted and fixed in the attachment hole 1022 formed in the metal panel member 1021, the first connector terminal 46 and the second connector terminal 47 are in a positional relationship as viewed from the metal panel member 1021. As described above, the metal panel member 1021 is supported at a fixed position and a fixed posture.

  Also according to the second embodiment, the first connector terminal 46 and the second connector terminal 47 are supported so as to be in parallel with each other when viewed from the metal panel member 1021 that is the attachment target component. It is possible to suppress deterioration of transmission characteristics in

  In particular, when the differential communication connector 44 is disposed in the vicinity of the metal panel member 1021 used as the ground, it is possible to effectively suppress deterioration of transmission characteristics in the differential communication path.

  Further, since the panel fixing portion 1062 is integrally formed on the bottom portion of the connector holding portion 70, the differential communication connector 44 is held by the connector holding portion 1070, so that the differential communication holding portion 1070 holds the differential communication. The connector 44 can be easily supported in a fixed posture with respect to the metal panel member 1021.

  Note that the connector holding portion and the panel fixing portion may be formed separately and may be combined by a combined structure or the like that fits separately.

  In addition, the panel fixing portion may be integrally formed with the connector housing of the differential communication connector.

  FIG. 19 is a schematic front view showing a differential communication connector support structure 1150 according to a ninth modification.

  In the ninth modification, the connector support portion 1160 includes a thick wall portion 1172 that surrounds the differential communication connector 44 so as to separate the differential communication connector 44 from other components.

  Here, the connector support portion 1160 is configured such that, in the connector support portion 1060 described in the second embodiment, the connector holding portion 1170 corresponding to the connector holding portion 1070 is thickened.

  More specifically, a housing hole 71 is formed in the connector holding portion 1170. The outer shape of the connector holding portion 1170 is a shape surrounded by a curved surface that protrudes outward when the connector holding portion 1170 is viewed from the front. The thickness dimension of the thick surrounding portion 1172 between the inner peripheral surface of the accommodation hole 71 and the connector holding portion 1170 is larger than the general thickness dimension required for holding the differential communication connector 44, The size is set so as to suppress the deterioration of the transmission characteristics due to the members.

  According to this modification, the differential communication connector 44 can be separated from other components by the thick-walled portion 1172. As other parts, it may be an electric wire W or the like. As a result, the transmission characteristics in the differential communication path are hardly affected by other components, and deterioration of the transmission characteristics in the differential communication path can be suppressed.

However, in the above configuration, the portion where the differential communication connector affects transmission characteristics, particularly a portion containing metal, etc. Applicable when mounted on.

  In each of the above examples, the differential communication connector has been described as an example including only one set of the first connector terminal and the second connector terminal. However, the first connector terminal and the second connector terminal are arranged in the same parallel direction. The present invention can also be applied when a plurality of sets are included. For example, the above-described configurations can be applied to a 4-pole differential communication connector and an 8-pole differential communication connector.

  In addition, each structure demonstrated by each said embodiment and each modification can be suitably combined unless it mutually contradicts.
