Description

  The present invention relates to a press contact blade terminal connector of an electrical component, and more specifically to a structure of a press contact blade terminal connector that presses an electric wire held in an electric wire holder to a press contact blade terminal provided in an electrical component housing.

  When connecting electric wires such as power lines and signal lines to various electrical components mounted on vehicles such as automobiles, as described in Patent Document 1, wiring using a wire harness is widely adopted. Yes. In the example shown in this document, a plurality of electric wires constituting a wire harness connected to a plurality of in-vehicle electrical components (for example, various indoor lamps) are aligned and held in an electric wire holder, An electric wire holder is attached to an electrical component housing provided with a plurality of press contact blade terminals, and the plurality of wires are formed so as to be able to press contact with corresponding press contact blade terminals at a time. In particular, according to the same document, a plurality of electric wires at arbitrary positions of the wire harness as well as both ends of the wire harness can be aligned and held in the electric wire holder to be branched and connected to the electrical component.

  In general, as described in the same document, the press contact blade terminal cuts the covering portion of the electric wire with a blade formed by making a pair of blades face each other and narrowing the blade edge interval from the front end side toward the rear end side. The core wire portion of the electric wire is press-contacted by a press-contact groove formed to extend to the rear ends of the pair of blades. Thus, when the electric wire is press-fitted from the blade edge side of the press contact blade terminal, the insulation coating of the electric wire is cut and the core wire is exposed, and when the electric wire is further pressed, the exposed portion of the core wire is press-fitted into the press contact groove, and the core wire and the press contact blade The terminal is electrically connected.

  The thus formed press contact blade terminal is connected to a circuit conductor such as a bus bar of the electrical component, and is fixed to a holder mounting portion formed in the electrical component housing to which the electric wire holder is mounted. In order to press-fit a plurality of electric wires aligned and held in the electric wire holder into a plurality of press contact blade terminals, one end of the electric wire holder is rotatably supported with respect to the electrical component housing, and the electric wire holder is tilted by the rotation and plural A holder mounting portion is formed in which the electric wire is inserted into the press contact blade terminal and pressed. For example, the holder mounting portion has a pair of rotating shafts provided to protrude from the corresponding side surfaces of the end portion of the electric wire holder, and a semicircular arc-shaped shaft supporting surface that receives the pair of rotating shafts of the electric wire holder. A pair of shaft support grooves are formed in the electrical component housing. Further, a rotation restricting member provided at a position where one end of the electric wire holder that rotates as the electric wire holder rotates in accordance with the completion position of the press contact of the electric wire to the press contact blade terminal, and a lower housing of the electric wire holder And a lock portion for fixing the wire holder to the housing by engaging with a housing side engaging portion formed on the housing.

  By the way, according to the structure of the press contact blade terminal connector described in Patent Document 1, the press contact of the wire to the press contact blade terminal is completed by the feeling that the end of the wire holder is in contact with the rotation regulating member. Can be judged. Alternatively, it can be determined that the press contact has been completed based on the operation sound of the lock portion that engages the holder side engaging portion provided in the wire holder and the housing side engaging portion formed in the housing.

  However, the electric wire holder described in Patent Document 1 is not considered for confirming that a plurality of electric wires are aligned and held at predetermined positions. That is, the electric wire holder of the same document is composed of an upper housing and a lower housing that are formed to be openable and closable via a hinge member, and by engaging engagement portions formed on opposing surfaces of these members, Is determined. In addition, a plurality of wire holding grooves are formed in alignment on the facing surfaces of the upper housing and the lower housing, and the wires are held between the facing wire holding grooves. However, even if multiple wires are installed at the position of the wire holding groove on one side, when the upper housing and the lower housing are closed and the wires are clamped, whether or not the wires are correctly fitted in the upper and lower wire holding grooves. It is difficult to get a feel of In other words, even when the upper housing and the lower housing are closed and the engaging portions are engaged, for example, if the engaging margin of the engaging portions is deviated from an intended value for some reason, the upper and lower electric wire holding grooves do not face each other correctly. For this reason, there is a possibility that the electric wires may be in a semi-fitted state where they are not properly fitted into the upper and lower electric wire holding grooves. When such a semi-fitted state occurs, the relative position of the electric wire and the press contact blade terminal may be shifted, and a press contact failure may occur.

  The problem to be solved by the present invention is an electric wire holder configured to fit and hold an electric wire in an electric wire holding groove formed on an opposing surface of an upper housing and a lower housing formed to be openable and closable via a hinge. An object of the present invention is to provide a press contact blade terminal connector capable of detecting the occurrence of a semi-fitted state of an electric wire in an electric wire holding groove.

  In order to solve the above problems, the present invention is formed on the facing surface by engaging an engaging portion formed on the facing surface of the upper housing and the lower housing formed to be openable and closable via a hinge member. An electric wire holder that fits and holds an electric wire in the electric wire holding groove, an electrical component housing that includes a press contact blade terminal that presses the core wire by cutting the sheath of the electric wire, and rotates with respect to the electrical component housing A holder mounting portion formed to rotate the wire holder supported so as to insert the electric wire into the press contact blade terminal; the holder mounting portion from the wire holding groove of the wire holder; A pair of pivot shafts provided so as to protrude from corresponding side surfaces of the one end apart from each other, and a shaft support surface provided on the electrical component housing for receiving the pair of pivot shafts of the wire holder In the press contact blade terminal connector comprising the shaft support groove, the rotating shaft of the wire holder is formed by a pair of semi-cylindrical members formed in the upper housing and the lower housing, and the upper housing and the It is characterized by being formed by joining the divided surfaces of the semi-cylindrical member at a position where the lower housing is closed.

  According to the present invention, when the electric wire is positioned in the electric wire holding groove of the electric wire holder, the upper housing and the lower housing are closed, the electric wire is sandwiched and the engaging portion is engaged, the semi-cylindrical members of the upper housing and the lower housing The split surfaces are joined to form a cylindrical rotation shaft of the electric wire holder. Then, the electric wire holder is held with the rotary shaft down, and the rotary shaft enters the shaft support surface of the shaft support groove while standing on the mounting surface of the electrical component housing. Rotate the rotation axis of the holder. In particular, the electric wire holder is gripped in a direction in which the lower housing of the electric wire holder faces the press contact blade terminal of the electric component housing. And if it rotates to a predetermined position, the electric wire clamped by the electric wire holder will be press-fitted in the press contact blade terminal provided in the electrical component housing, and press contact will be completed. At this time, if the positions of the wire holding grooves facing each other between the upper housing and the lower housing are shifted, a semi-fitted state in which the wires are not properly fitted into the wire holding grooves occurs. In that case, the joining position of the semi-cylindrical members of the upper housing and the lower housing is shifted, and the rotating shaft of the electric wire holder does not become cylindrical. Therefore, it is difficult for the rotating shaft to enter the shaft support groove, or even if it enters, it is difficult to rotate, so that it is possible to detect that the electric wire is in a semi-fitted state. Thereby, the electric wire clamping by the electric wire holder is performed again, and the assembly work of the electric wire to the electric wire holder is adjusted so that the electric wire is fitted into the electric wire holding groove.

  In the above case, since the hinge member that connects the upper housing and the lower housing is relatively easily deformed, and there is a certain margin in the engagement allowance of the engaging portion that engages both, the upper housing and the lower housing May be displaced relative to each other in a direction perpendicular to the rotation axis of the hinge member. Therefore, it is preferable to form the split surfaces of the semi-cylindrical member of the present invention in an uneven structure that fits together. According to this, since the rotating shaft of the electric wire holder does not become a cylindrical shape unless the unevenness of the dividing surface is fitted, the rotating shaft cannot enter the shaft support groove, so that the electric wire is in a semi-fitted state. It can be detected reliably.

  The unevenness in the above case is formed by extending a convex part of a small-diameter semi-cylinder on one dividing surface in the axial direction, and extending a concave part that fits the convex part on the other dividing surface in the axial direction. Can be formed. In this case, the semi-cylindrical member formed in the upper housing is formed such that a flat surface obtained by cutting a part of the circular arc portion of the outer peripheral surface of the cylinder is formed in parallel with the dividing surface, and the shaft supporting groove provided in the electrical component housing is formed. By forming the groove width of the entrance portion to be narrower by the thickness of the cut arc portion, the step portion of the groove wall formed at the entrance portion functions as a rotation restricting member. That is, the flat surface of the rotating shaft comes into contact with the step portion in the shaft support groove, and the rotation of the electric wire holder is restricted. Therefore, in addition to the effects described above, the lever of the lever can be moved closer to the position of the fulcrum and the point of action of the acting force when pressing the opposite end of the wire holder to press-fit the wire into the press contact blade terminal. Can reduce the pressing force.

  According to the present invention, in an electric wire holder configured to fit and hold an electric wire in an electric wire holding groove formed on opposing surfaces of an upper housing and a lower housing formed to be openable and closable via a hinge, Generation of a semi-fitted state of the electric wire can be detected.

Hereinafter, the press contact blade terminal connector of the present invention will be described based on Example 1 shown in FIGS. The first embodiment will be described assuming that the press contact blade terminal connector of the present invention is applied to an indoor lamp that is an example of various electrical components mounted on a vehicle such as an automobile. However, the press contact blade terminal connector of the present invention is not limited to an indoor lamp, and can be applied to a connector having a press contact blade terminal for connecting a power line or a signal line to various electrical components.

  FIG. 3 is a perspective configuration diagram of a resin housing 10 that constitutes an indoor lamp that is an electrical component. Although not shown, the housing 10 is formed so as to accommodate one or more lamps and components such as a switch knob. The housing 10 is provided with a circuit conductor such as a copper alloy bus bar 11 for supplying power to the lamp. As shown in FIGS. 1A and 1B, the bus bar 11 is connected with a plurality of press contact blade terminals 13 each having a press contact blade portion 17 to which a plurality of electric wires for supplying power to the electrical components are connected from the outside. Has been.

  Each press contact blade terminal 13 is formed of a copper alloy plate member and is held by a housing member 18 of a holder mounting portion 14 formed in the housing 10. Moreover, the press contact blade part 17 has a pair of blades provided by opening the cutting edge of the opposing blade that cuts the coating of the electric wire, and a press contact groove that presses the core wire extended from the base ends of the pair of blades. Is formed. The proximal ends of the pair of blades of the press contact blade portion 17 have a gap equivalent to the core wire diameter of the electric wire 34, and a press contact groove having a groove width narrower than the core wire diameter extends from the gap. The press contact blade portion 17 is backed by a resin reinforcing member 12.

  Next, the configuration of the wire holder 30 according to the feature of the present embodiment will be described with reference to FIG. The electric wire holder 30 aligns and holds the plurality of electric wires 34 that are press-contacted to the press contact blade terminals 13 and is fixed so as not to move due to a reaction force or the like when press-fitted into the press contact blade portion 17. In addition, when wiring power lines and signal lines to in-vehicle electrical components, wiring using a wire harness is widely adopted, and a connector for connecting to a terminal such as a power source is provided at one end of a bundle of wire harnesses. ing. In addition, a plurality of electric wires are aligned and held in the middle of the wire harness and / or at the end, and an electric wire holder 30 is provided for firmly holding the electric wires on the press contact blade terminals 13 of the electrical component so that they can be pressed. As shown in the figure, the electric wire holder 30 is formed such that a resin-made upper housing 31 and lower housing 32 can be opened and closed in a direction indicated by an arrow 42 by a hinge member 33 having a rotating shaft parallel to the electric wire 34. On the opposing surfaces of the upper housing 31 and the lower housing 32 that are opened and closed, a plurality of wire holding groove members 35a and 35b that hold a plurality (three in the illustrated example) of wires 34 in alignment are respectively provided on both side surfaces of each housing. It is provided in the position. Each electric wire holding groove member 35a, b is provided with a plurality of half electric wire holding grooves 37 according to the arrangement of the electric wires. An engaging portion 36 is formed at the opposite end of the hinge member 33 of the upper housing 31 and the lower housing 32 so as to engage with each other and maintain the closed state of both. In the present embodiment, a gate-shaped engaging portion 36a is provided on the upper housing 31 side, and a hook-shaped engaging portion 36b is provided on the lower housing 32 side to be engaged with the beam of the gate-shaped engaging portion 36a.

  Here, with reference to FIG. 1, the structure of the holder mounting part which is the characteristic part of the present Example 1 is demonstrated in detail. FIG. 1 schematically shows the configuration of the holder mounting portion 14 around the press contact blade terminal 13 and a portion related to the electric wire holder 30 in order to avoid the complexity of the drawing. As shown in FIG. 6A, the holder mounting portion 14 includes a housing member 18, and the number of press contact blade terminals 13 corresponding to the number of wires to be connected is arranged on the upper surface of the housing member 18. In accordance with the alignment, the blade edge of the press contact blade portion 17 is disposed facing upward. A shaft in which a shaft support groove 19 having a semicircular arc-shaped bottom portion that rotatably supports a rotation shaft 50 formed on the electric wire holder 30 is formed on the upper surface of the housing member 18 on the right side in the drawing of the press contact blade terminal 13. The support member 20 is provided upright. That is, the shaft support groove 19 is opened above the shaft support member 20, and the rotating shaft 50 is opened at the upper end of the shaft support groove 19 in the state where the electric wire holder 30 is erected as shown in FIG. It is designed to be installed from the beginning.

  In addition, the wire holder 30 is engaged with the holder mounting portion 14 by engaging with the engagement portion 43 provided on the wire holder 30 on the upper surface of the housing member 18 on the opposite side of the shaft support groove 19 with the press contact blade terminal 13 interposed therebetween. A lock portion 21 is provided for restraining. Further, the end 30 a of the electric wire holder 30 abuts on the upper surface of the housing member 18 when the electric wire holder 30 is rotated around the shaft support groove 19 in the direction of the arrow 24 and engaged with the lock portion 21. A rotation restricting member 22 that restricts the rotation of the electric wire holder 30 in the direction of the arrow 24 (downward in the drawing) is provided. That is, the rotation restricting member 22 is provided in the rotation path of the end 30 a of the electric wire holder 30. Therefore, when the rotating shaft 50 of the electric wire holder 30 enters the axial support groove 19, the rotating shaft 50 is axially supported with the end 30 a of the electric wire holder 30 facing down, that is, with the electric wire holder 30 standing up. Unless it enters from the upper end opening of the groove 19, the rotation restricting member 22 interferes with the assembly.

  Further, the lock portion 21 is provided upright on the upper surface of the holder mounting portion 18 of the electrical component housing 10 and engages with the engagement portion 43 provided in the upper housing 31 of the wire holder 30 as described above. It is formed as follows.

  Next, the structure of the rotating shaft 50 of the electric wire holder which is a characteristic part of the present embodiment will be described with reference to FIG. The rotating shaft 50 according to the first embodiment includes a pair of semi-cylindrical members 50a and 50b obtained by dividing one cylindrical member into two substantially along the axial direction. For example, as shown in FIG. 2A, a semi-cylindrical member 50a is formed by projecting from both side surfaces of the upper housing 31 near the hinge member 33, and correspondingly projecting from both side surfaces of the lower housing 32. A semi-cylindrical member 50b is formed. When the upper housing 31 and the lower housing 32 are closed, the split surfaces 51 of the semi-cylindrical members 50a and 50b are joined to form a cylindrical rotating shaft 50. 2C and 2D show radial cross sections of the semi-cylindrical member 50a and the semi-cylindrical member 50b, respectively, and FIG. 2E shows the radial cross section of the rotating shaft 50. FIG. As shown in these drawings, the rotation shaft 50 of the present embodiment extends in the axial direction a semi-cylindrical convex portion 52 having a diameter smaller than the diameter of the rotation shaft 50 on the split surface 51a of the semi-cylindrical member 50a. A recess 53 of a semicircular groove that fits into the protrusion 52 is formed on the split surface 51b of the other semi-cylindrical member 50b so as to extend in the axial direction.

  The operation of press-fitting the electric wire 34 into the press contact blade terminal 13 using the press contact blade terminal connector of Example 1 configured as described above will be described. First, as shown in FIG. 2A, the upper housing 31 and the lower housing 32 of the electric wire holder 30 are opened, and after the electric wires 34 are arranged in the electric wire holding grooves 37, the upper housing 31 and the lower housing 32 are closed. Engage the engaging portions 36a, b. Thereby, the electric wire 34 is fitted in the electric wire holding groove 37 and is firmly held by the electric wire holder 30. Next, when the electric wire 34 is press-fitted into the press-contact blade portion 17 of the press-contact blade terminal 13, as shown in FIG. To the bottom bearing surface. When the electric wire holder 30 is rotated in the direction of the arrow 24 in the drawing, each electric wire 34 is rotated along an arcuate rotation locus 38 centering on the rotation shaft 50. Thereby, each electric wire 34 is press-fitted into the press-contact blade portion 17 of the press-contact blade terminal 13, the insulating coating is cut, and the exposed core wire is pressed into the press-contact groove. In this way, as shown in FIG. 1B, when the electric wires 34 reach a predetermined position for completion of press-fitting of the press contact blade portion 17 with the end portion 30a down, the alignment of the electric wires 34 aligned and held is arranged. The surface 39 is substantially parallel to the reference surface 23 set on the upper surface of the housing member 18.

  In the above-described press-fitting process of the electric wire, the end 30 a of the electric wire holder 30 contacts the lower surface 22 a of the protrusion of the rotation restricting member 22. Therefore, the contact between the end portion 30a of the electric wire holder 30 and the lower surface 22a of the rotation restricting member 22 is turned as a fulcrum. As a result, the electric wires 34 aligned and held by the force 45 applied to the operation lever 44 of the electric wire holder 30 are press-fitted into the press contact blade portion 17 by a larger acting force, and the electric wire 34 and the electrical circuit conductor of the electrical component are electrically connected. A connection is made. In this state, the engaging portion 43 of the electric wire holder 30 engages with the lock portion 21 of the holder mounting portion 14 and is firmly connected.

  The effect of Example 1 comprised in this way is demonstrated using FIG.4 and FIG.5. FIG. 4A shows a comparative example in which the rotating shaft 50 is divided into two semi-cylindrical members 60a and 60b along the axis. According to this comparative example, as shown in FIG. 4B, when the upper housing 31 and the lower housing 32 are shifted and engaged as shown by the arrow 61 in the figure, the electric wire holding grooves facing the upper housing and the lower housing are arranged. The position of 37 will shift. That is, the hinge member 33 that connects the upper housing 31 and the lower housing 32 is relatively easily deformed, and there is a certain margin in the engagement allowance of the engaging portion 36 that engages both. For this reason, the positions of the upper housing 31 and the lower housing 32 may be engaged with each other while being relatively displaced in the direction orthogonal to the rotation axis of the hinge member 33. In this case, a semi-fitted state where the electric wire 34 is not properly fitted into the electric wire holding groove 37 occurs, and the rotating shaft 50 of the electric wire holder 30 does not become a columnar shape. Therefore, even if the rotation shaft 50 can enter the shaft support groove 19, it becomes difficult to rotate, so that it is possible to detect that the electric wire 34 is in a semi-fitted state.

  On the other hand, in Example 1, as shown in FIGS. 2C to 2E, a semi-cylindrical convex portion 52 is formed to extend in the axial direction on the split surface 51a of the semi-cylindrical member 50a. A concave portion 53 that fits the convex portion 52 is formed on the dividing surface 51b of the semi-cylindrical member 50b so as to extend in the axial direction. Therefore, if the relative positions of the upper housing 31 and the lower housing 32 do not shift, the convex portion 52 fits into the concave portion 53 and the rotating shaft 50 becomes a columnar shape as shown in FIG. Therefore, as shown in FIG. 1A, the electric wire holder 30 can be held in an upright state so that the rotating shaft 50 can smoothly enter the shaft support groove 19. Further, since the rotation shaft 50 can be mounted to the bottom of the semicircular arc shape of the shaft support groove 19, the electric wire holder 30 can be smoothly rotated.

  By the way, in the case of the rotation shaft 50 of the first embodiment, the upper housing 31 and the lower housing 32 are engaged with each other for some reason, and as shown in FIGS. If a gap 56 is generated in the half cylinder member 50a, 50b, the split surfaces 51a, 51b of the semi-cylindrical members 50a, b are also formed between the convex part 52 and the concave part 53 and do not fit. Therefore, since the rotation shaft 50 does not become a columnar shape, the rotation shaft 50 cannot enter the shaft support groove 19 as shown in FIG. Can be detected.

  In Example 1, one split surface of the semi-cylindrical member has a shape in which the convex portion of the small-diameter semi-cylinder extends in the axial direction, and the other split surface has a concave portion that fits in the one convex portion in the axial direction. Although the shape is extended, the present invention is not limited to this. The point is that by forming irregularities that fit to each other on the opposing divided surfaces, the rotating shaft of the electric wire holder will not be cylindrical unless the irregularities of the divided surfaces are fitted, so the same effect as in the first embodiment is achieved. be able to.

(Example 2)
6 (a) is an external perspective view of the electric wire holder according to the second embodiment of the press contact blade terminal connector of the present invention, FIG. 6 (b) is a perspective view of the main part, and FIG. 6 (c) is the diameter of the rotating shaft 50. A direction sectional view is shown. In this embodiment, the radial cross section of the semi-cylindrical member 50a formed on the upper housing 31 of the rotating shaft 50 of the electric wire holder 30 of the first embodiment is changed, and the groove shape of the shaft support groove 19 is changed accordingly. It is in the point. Since other points are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

  As shown in these figures, the rotating shaft 50 of the electric wire holder 30 of the second embodiment is formed by cutting off a part of the arc portion of the outer peripheral surface of the semi-cylindrical member 50a formed in the upper housing 31 so that the flat surface 55 is formed. Is formed. The flat surface 55 is formed in parallel to the joint surface between the upper housing 31 and the lower housing 32. In other words, it is formed parallel to the flat surface of the dividing surface 51. Accordingly, as shown in FIG. 7, the groove width of the entrance portion of the shaft support groove 19 formed on the shaft support member 20 provided upright on the upper surface of the housing member 18 is the thickness of the cut arc portion. The step portion 19 b is formed in the groove wall 19 a of the shaft support groove 19.

  Thus, according to the second embodiment, when the electric wire holder 30 is to be mounted on the holder mounting portion 14 in the assembly posture shown in FIG. Since 55 enters the groove wall 19a side where the step portion 19b of FIG. 7A is formed, the rotating shaft 50 can be mounted in the shaft support groove 19 without any trouble. When the rotating shaft 50 reaches the bearing surface of the shaft support groove 19, when the wire holder 30 is rotated in the direction of the arrow 24 in FIG. 1, the rotating shaft 50 is rotated in the direction of the arrow 57 in FIG. 7. . When the electric wire holder 30 reaches the pressure contact completion position of the electric wire, the flat surface 55 of the drive shaft 50 comes into contact with the lower surface of the step portion 19b, and the rotation of the drive shaft 50 and consequently the rotation of the electric wire holder 30 is restricted. That is, the step portion 19b realizes the function of the rotation restricting member 22 of the first embodiment. As a result, the electric wire holder 30 is rotated with a contact point between the flat surface 55 of the rotation shaft 50 and the lower surface of the step portion 19b as a rotation restricting member. That is, the rotation shaft 50 is substantially a fulcrum, and the position of the fulcrum can be brought close to the pressure contact point of the electric wire. Therefore, the operation force 45 applied to the operation lever 44 causes the electric wire to be pressed against the pressure contact blade portion. 17 and the operating force 45 can be reduced.

  By the way, in the second embodiment, contrary to the assembly posture shown in FIG. 1A, the upper housing 31 side of the electric wire holder 30 is held in the rotating direction so as to be mounted on the holder mounting portion 14. For example, the flat surface 55 of the rotation shaft 50 enters along the opposite side of the groove wall 19a in which the step portion 19b of FIG. 7A is formed. However, the flat surface 55 becomes an obstacle just before the rotating shaft 50 reaches the bearing surface of the shaft support groove 19, and no further entry is possible. Therefore, when attaching the electric wire holder 30 to the holder attachment part 14, the incorrect assembly | attachment of the electric wire holder 30 can be prevented naturally.
