Description

  The present invention relates to a connector and a support device and method thereof.

Conventionally, a board connector is used to connect a cable to a circuit board such as a printed circuit board. Such a board connector is mounted on a circuit board and is fitted with a cable connector connected to an end of the cable. However, when mating with the cable connector, an external force such as a pressing force is applied from the cable connector to the board connector, and the connection between the board connector and the circuit board is damaged by the external force, The board will be damaged. In view of this, a technique has been proposed in which an external force is not transmitted to the connection portion between the board connector and the circuit board or the circuit board by supporting the board connector with a cover of a device including the circuit board (for example, a patent). Reference 1).
JP-A-10-233263

  However, in the conventional connector support device, due to the dimensional error of each member itself such as the mounting boss, the cover, the housing, or the dimensional error caused by the mounting work, the gap between the tip of the support protrusion and the outer surface of the cover is reduced. Since inevitable gaps occur, there is rattling in the fitting direction of the cable connector between the board connector and the cover that supports the board connector. Therefore, when the cable connector is fitted to the board connector, the pressing force and other external forces received by the board connector are not completely received by the cover but are transmitted to the circuit board. The transmitted external force causes the circuit board to be cracked or distorted, and the circuit board is damaged, or the connection part such as soldering that connects the board connector to the board is cracked, distorted, or peeled off. Connection reliability may be extremely lowered due to breakage or the like.

  The present invention solves the above-mentioned conventional problems, forms a concave groove portion on the outer surface of the housing that is inserted through the opening formed in the panel, and presses a part of the auxiliary support member into the concave groove portion. By moving the housing in the direction to be inserted into the panel and press-fitting into the opening, rattling between the housing and the panel is eliminated, and the housing moves relative to the panel in any of the three XYZ directions. Therefore, it is an object of the present invention to reliably prevent the external force received by the connector from being transmitted to the board by the panel.

  For this purpose, in the connector of the present invention, the support member has a housing and a terminal loaded in the housing, is mounted on the board, and the housing is disposed above the mounting surface of the board. The housing includes a supported portion that is inserted through an opening formed in the support member, and a recessed groove portion that is formed on an outer surface, and is engaged with the support member. When at least a part of the auxiliary support member is press-fitted into the concave groove part, at least a part of the supported part is press-fitted into the opening.

  According to the present invention, the connector forms a concave groove portion on the outer surface of the housing that is inserted through the opening formed in the panel, and a part of the auxiliary support member is press-fitted into the concave groove portion, whereby the housing is inserted into the panel. It is moved in the insertion direction and press-fitted into the opening. As a result, there is no rattling between the housing and the panel, the housing does not move relative to the panel in any of the three XYZ directions, the panel receives the external force received by the connector, and the external force is Since it is possible to reliably prevent transmission to the substrate, connection reliability can be improved.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In addition, the conductive traces formed on the substrate 91 are protected from dust, water, and the like, and function as a support member that supports the connector 1. Therefore, a connector insertion opening 96 is formed in the panel 95 as an opening through which the housing 11 of the connector 1 is inserted. The panel 95 is indirectly or directly fixed to the substrate 91 and is held so that the distance from the substrate 91 is constant. For example, the panel 95 may be formed integrally with a housing of an electronic device including the substrate 91, or is fixed to the substrate 91 via a fixing member such as a screw (not shown). There may be.

  In the present embodiment, expressions indicating directions such as upper, lower, left, right, front, rear, etc. used for explaining the configuration and operation of each part of the connector 1 and other members are absolute. It is not a thing but a relative thing, and it is suitable when each part of the connector 1 and other members has a posture shown in the figure, but when the posture changes, it changes according to the change of the posture. Should be interpreted.

  The housing 11 of the connector 1 is integrally formed of an insulating material such as synthetic resin. The housing 11 is formed with a fitting opening 23, a fitting cylinder part 12 as a fitting part to be fitted with the mating connector 101, a board side cylinder part 13 attached to the board 91, and the fitting cylinder part 12. And the board-side cylinder part 13, and a supported part 15 inserted through the connector insertion opening 96 and a bottom plate part 14 that closes the bottom part of the fitting cylinder part 12. In the example shown in the figure, the fitting tube portion 12 and the substrate side tube portion 13 have a rectangular tube shape with a substantially rectangular cross section, but the cross section may have any shape, for example, It may be circular, elliptical, or the like. In addition, a rectangular cutout 19 is formed on the two opposing side surfaces of the substrate side cylinder portion 13, but the shape and size of the cutout 19 can be arbitrarily set, and further omitted. You can also

  In the connector 1, a plurality of terminals 61 made of a highly conductive material such as metal are arranged in a predetermined arrangement, for example, a plurality of columns such as 4 rows and 12 columns shown in FIG. 4. It is loaded. The arrangement of the terminals 61 can be set as appropriate. The terminal 61 is inserted into and connected to a held portion 62 that is press-fitted and held in the bottom plate portion 14 of the housing 11, and a through-hole 92 that is connected to one of the held portions 62 and formed in the substrate 91. And a contact portion 64 that is connected to the other of the held portion 62 and extends into the fitting opening 23 and contacts the mating terminal of the mating connector 101. In the example shown in the figure, two types of terminals 61 are shown, but the number of types of terminals 61 may be singular, plural, or any number. In the present embodiment, all types of terminals are described as terminals 61.

  In addition to the through hole 92, the board 91 has a tab engagement hole 93 into which an engagement tab 28 protruding from the board side cylinder portion 13 of the housing 11 is inserted, and the board 91 as a housing. A fixing opening 94 for inserting fixing means such as screws and bolts for fixing is formed. Note that a conductive trace (not shown) is connected to at least a part of the through hole 92, so that the terminal 61 in which the leg 63 is inserted and connected to the through hole 92 is electrically connected to the corresponding conductive trace. Connected. Then, the leg portion 63 of the terminal 61 is fixed to the through hole 92 by fixing means such as soldering, and the engaging tab 28 is fixed to the tab engaging hole 93 by fixing means such as an adhesive as necessary. Thus, the connector 1 is fixed to the substrate 91. Further, in the example shown in the figure, the fixing openings 94 are respectively formed at the four corners of the substrate 91. However, the number and positions of the fixing openings 94 can be appropriately set, and further omitted. You can also.

  The connector 1 is supported by being fixed to the panel 95 by attaching a pair of stopper members 41 as auxiliary support members engaged with the panel 95. Further, the housing 11 has a pair of engaging groove portions 16 formed as concave grooves defined on the outer surface of the housing 11 and defined by the lower surface of the support portion 20 and the upper surface of the supported portion 15. The supported portion 15 of the housing 11 has a substantially rectangular prismatic shape, like the fitting cylinder portion 12 and the substrate side cylinder portion 13, and extends along a pair of short sides of the rectangle. The engaging groove portions 16 are formed so as to face each other. The housing 11 is fixed to and supported by the panel 95 by press-fitting a part of the stopper member 41 into each of the engagement groove portions 16.

  Here, the stopper member 41 is a member made of an insulating material such as a synthetic resin, a metal material, or the like. The stopper member 41 extends forward from the elongated bar-shaped main body portion 42 and is press-fitted into the engagement groove portion 16. A press-fit portion 43, a plurality of tapered ribs 44 formed on the upper surface of the press-fit portion 43, a locking arm portion 46 extending forward from both ends of the main body portion 42, and the locking arm portion 46 is provided with a locking projection 47 formed at the tip of 46, that is, the free end. On the other hand, a locking recess 17 that locks the locking protrusion 47 is formed on a pair of long sides of the rectangle in the supported portion 15.

  Further, taper ribs 18 as a plurality of rib portions are formed at portions near the substrate side cylinder portion 13 on each side of the supported portion 15. Then, when the press-fitting portion 43 of the stopper member 41 is press-fitted into the engaging groove portion 16, the portion of the supported portion 15 near the board side cylinder portion 13 is press-fitted into the connector insertion opening 96, whereby the housing 11 is fixed to the panel 95. Has been supported. As shown in FIG. 4, when the press-fitting of the press-fitting portion 43 into the engaging groove portion 16 is completed, the locking projection 47 is locked to the locking recess 17, so that the stopper member 41 is locked and the housing 11 will not leave.

  A connector engagement protrusion 22 that engages with an engagement lever 121 (described later) of the mating connector 101 is formed on the outer side surface of the rectangular long side of the fitting cylinder portion 12 of the housing 11. In addition, the connector engagement protrusion 22 may be formed in the outer surface of a rectangular short side, and can be set suitably. Further, on the inner side surface of the fitting tube portion 12, a positioning protrusion 24 and a reverse prevention protrusion 25 that engage with a positioning groove 114 and a reverse prevention groove 115, which will be described later, of the counterpart connector 101 are provided. Is formed so as to extend in the insertion / extraction direction (vertical direction in FIG. 3) in which the connector 1 is inserted / extracted. Further, on the upper surface of the bottom plate portion 14, a terminal protection convex portion 26 that extends into the fitting opening 23 and is accommodated in the accommodating concave portion of the counterpart connector 101 is formed. Further, a terminal holding convex portion 27 that covers and holds the held portion 62 of the terminal 61 is formed on the lower surface of the bottom plate portion 14.

  Next, the configuration of the connector 1 will be described in detail.

  5 is a perspective view of the connector according to the embodiment of the present invention, FIG. 6 is a side view of the connector according to the embodiment of the present invention, FIG. 7 is a top view of the connector according to the embodiment of the present invention, and FIG. 9 is a bottom view of the connector in the embodiment of the present invention, FIG. 9 is a sectional view of the connector in the embodiment of the present invention, a sectional view taken along line BB in FIG. 6, and FIG. FIG. 10 is an enlarged sectional view of a portion, and is an enlarged view of a portion C in FIG. 9.

  In the example shown in the figure, two tapered ribs 18 are formed on each side of the supported portion 15, but the number can be changed as appropriate. And the taper surface 18a inclined with respect to the said insertion / extraction direction is formed in the upper end of each taper rib 18, Thereby, the outer surface of the taper rib 18 protrudes largely from the outer surface of the supported part 15 in the downward direction. It becomes. Since the dimension of the outer surface of the supported portion 15 is formed to be slightly smaller than the dimension of the inner surface of the connector insertion opening 96, the dimension between the outer surface of the supported portion 15 and the inner surface of the connector insertion opening 96 is small. Is formed with a gap, and the supported portion 15 can be inserted into the connector insertion opening 96 from below the panel 95. It is desirable that a tapered chamfered portion 15 a is formed on the upper edge of the supported portion 15. Thereby, the outer surface becomes smaller at the upper end of the supported portion 15, and the supported portion 15 can be smoothly inserted into the connector insertion opening 96.

  Further, the protruding amount of the outer side surface of the lower end of the taper rib 18 from the outer side surface of the supported portion 15 is between the inner side surface of the connector insertion opening 96 and the outer side surface of the supported portion 15 inserted into the connector insertion opening 96. It is set to be larger than the gap between them. Therefore, when the portion of the supported portion 15 near the board side cylinder portion 13 is inserted into the connector insertion opening 96, the portion is pressed into the connector insertion opening 96. Since the outer side surface of the board side cylinder portion 13 is larger than the inner side surface of the connector insertion opening 96, the board side cylinder portion 13 is not inserted into the connector insertion opening 96.

  The positioning protrusion 24 formed on the inner surface of the fitting cylinder portion 12 is disposed in the width direction of the fitting opening 23, that is, in the center of the long side of the rectangle, and the inversion prevention protrusion 25 is positioned. It is arranged on both sides of the strip 24. Further, the distance between the reverse prevention protrusions 25 and the positioning protrusions 24 on both sides is set to be non-uniform, and similarly, the distance between the reverse prevention groove 115 and the positioning groove 114 of the mating connector 101 is also non-uniform. It is set to be. The inversion prevention groove 115 and the positioning groove 114 are disposed so as to correspond to the inversion prevention protrusion 25 and the positioning protrusion 24. Therefore, when the direction of the convex portion 112 (described later) of the mating connector 101 is reversed, that is, when reversed with respect to the normal posture, the positions of the reversal prevention groove 115 and the reversal prevention protrusion 25 correspond. Therefore, the convex portion 112 cannot be inserted into the fitting opening 23. Thereby, it can be reliably prevented that the mating connector 101 is fitted to the connector 1 in an inverted state, that is, erroneous insertion.

  Further, the terminal protection convex portions 26 are also arranged asymmetrically with respect to the width direction of the fitting opening 23. And the accommodation recessed part of the other party connector 101 is similarly arrange | positioned asymmetrical regarding the width direction. Therefore, when the direction of the convex portion 112 of the mating connector 101 is reversed with respect to the normal posture, the positions of the terminal protective convex portion 26 and the accommodating concave portion do not correspond to each other. It cannot be inserted into the fitting opening 23 deeper than the upper end of 26. As shown in FIG. 9, since the upper end of the terminal protection convex portion 26 is located above the upper end of the contact portion 64 of the terminal 61, the convex portion of the mating connector 101 thus inverted with respect to the normal posture. It is reliably prevented that the 112 abuts against the contact portion 64 and damages the contact portion 64.

  Further, since the notch 19 is formed in the substrate side cylinder portion 13, the operator can visually confirm from the outside whether or not the leg portion 63 of the terminal 61 is securely fixed to the through hole 92 by soldering or the like. Can do.

  Further, it is desirable that tapered chamfered portions 16 a are formed on the upper and lower edges of the entrance of the engaging groove portion 16. As a result, the vertical dimension of the inlet end of the engagement groove 16 becomes larger, and the press-fit portion 43 can be inserted into the engagement groove 16 more smoothly.

  Next, the configuration of the stopper member 41 will be described in detail.

  11 is a perspective view of the stopper member in the embodiment of the present invention, FIG. 12 is a cross-sectional view of the stopper member in the embodiment of the present invention, and is a cross-sectional view taken along the line DD in FIG.

  The stopper member 41 has a locking arm portion 46 extending forward (rightward in FIG. 12) from both ends of the elongated rod-like main body portion 42, and has a substantially U-shape when viewed from above. Further, the side cross section of the stopper member 41 is substantially L-shaped, and the base end side edge of the elongated plate-like press-fit portion 43 is connected to the lower end side edge of the main body portion 42. The lower surface of the main body portion 42 and the lower surface of the press-fit portion 43 are flush with each other. Further, the lower surface of the locking arm portion 46 is also flush with the lower surfaces of the main body portion 42 and the press-fit portion 43, that is, the entire lower surface of the stopper member 41 is a single flat surface. It is desirable.

  In the example shown in the figure, three taper ribs 44 are formed on the upper surface of the press-fit portion 43, but the number can be changed as appropriate. And the taper surface 44a inclined with respect to the press-fitting direction of the press-fit portion 43, that is, the extending direction (front) of the press-fit portion 43 is formed at the tip of each taper rib 44. The closer to the back, that is, the closer to the main body portion 42, the larger the protrusion from the upper surface of the press-fit portion 43. Since the thickness of the press-fit portion 43, that is, the vertical dimension is formed to be slightly smaller than the vertical dimension of the engagement groove 16 of the housing 11, the engagement groove is formed from the side of the supported portion 15. The press-fit portion 43 can be inserted into the inside 16. It is desirable that a chamfered portion 43 a that is flush with the tapered surface 44 a is formed on the upper side of the tip of the press-fit portion 43. Thereby, the dimension of the up-down direction in the front-end | tip of the press-fit part 43 becomes smaller, and the press-fit part 43 can be smoothly inserted in the engagement groove part 16. FIG.

  Further, the protruding amount of the upper surface of the press-fitting portion 43 from the upper surface of the tapered rib 44 adjacent to the main body portion 42 is larger than the difference between the vertical dimension of the engagement groove portion 16 and the vertical dimension of the press-fit portion 43. It is set to be. Therefore, when the portion of the press-fit portion 43 near the main body portion 42 is inserted into the engagement groove portion 16, the press-fit portion 43 is pressed into the engagement groove portion 16. Since the vertical dimension of the main body part 42 is larger than the vertical dimension of the engagement groove part 16, the main body part 42 is not inserted into the engagement groove part 16.

  Next, a method of fixing the connector 1 having the above configuration to the panel 95 will be described.

  FIG. 13 is a cross-sectional side view of a main part showing a first step of fixing the connector to the panel in the embodiment of the present invention, and FIG. 14 is a perspective view showing a second step of fixing the connector to the panel in the embodiment of the present invention. FIG. 15 is a sectional side view showing a main part of a third step of fixing the connector to the panel according to the embodiment of the present invention. FIG. 16 is a main part of the fourth step of fixing the connector to the panel according to the embodiment of the present invention. FIG. 17 is a fragmentary sectional side view showing the fifth step of fixing the connector to the panel according to the embodiment of the present invention.

  First, the housing 11 of the connector 1 mounted on the board 91 is moved up relative to the panel 95 from below the panel 95 and inserted into the connector insertion opening 96 by the operator's manual work. Since the outer surface of the fitting cylinder portion 12 is formed smaller than the outer surface of the supported portion 15 and is therefore smaller than the inner surface of the connector insertion opening 96, as shown in FIG. It can be easily inserted into 96.

  Subsequently, when the housing 11 is further raised with respect to the panel 95, the supported portion 15 is inserted into the connector insertion opening 96. Then, when the tapered surface 18a of the tapered rib 18 formed in the portion of the supported portion 15 near the substrate side cylinder portion 13 comes into contact with the lower end edge inside the connector insertion opening 96, the ascent of the housing 11 stops. In this case, a portion of the supported portion 15 near the fitting cylinder portion 12 is exposed to a considerable extent above the panel 95 as shown in FIG. The engaging groove 16 formed in the portion near the fitting cylinder 12 is also exposed to a considerable extent above the panel 95. It is desirable that a tapered chamfered portion 96 a is formed at the lower end edge of the connector insertion opening 96. As a result, the inner side surface of the lower end of the connector insertion opening 96 becomes larger, and the connector 1 can be easily guided to the connector insertion opening 96, and the supported portion 15 can be smoothly inserted into the connector insertion opening 96. Can do.

  Subsequently, as shown in FIG. 14, the pair of stopper members 41 are moved from both sides of the supported portion 15 toward the engagement groove portion 16. In this case, as shown in FIG. 15, the position of the stopper member 41 is controlled so that the tip of the press-fit portion 43 faces the engagement groove portion 16, and its lower surface is along the upper surface of the panel 95. The member 41 is slid. Since the entire lower surface of the stopper member 41 is a single flat surface, the stopper member 41 can be slid more smoothly.

  Subsequently, as shown in FIG. 16, when the tip end of the press-fit portion 43 of the stopper member 41 is inserted into the engagement groove portion 16, the inclined tapered surface 44 a of the taper rib 44 is the upper end edge of the entrance of the engagement groove portion 16. Abut. In this case, as described above, the tapered surface 18 a of the tapered rib 18 of the supported portion 15 is in contact with the lower end edge inside the connector insertion opening 96.

  Then, when the stopper member 41 is further moved to the left in FIG. 16 and the press-fit portion 43 is pushed into the engagement groove portion 16, that is, press-fitted, the upper end edge of the entrance of the engagement groove portion 16 is inclined. Accordingly, the entire housing 11 is raised relative to the stopper member 41 and the panel 95 that supports the stopper member 41 from below. Then, the lower end edge on the inner side of the connector insertion opening 96 relatively moves along the inclined tapered surface 18a of the tapered rib 18 formed in the supported portion 15, whereby the connector insertion opening 96 is expanded in the direction in which the connector insertion opening 96 is expanded. Receive power. That is, the supported portion 15 is press-fitted into the connector insertion opening 96 so as to expand the connector insertion opening 96.

  As shown in FIG. 17, when the press-fitting of the stopper member 41 into the engagement groove portion 16 is completed, a part of the lower surface of the stopper member 41 engages with the peripheral edge of the connector insertion opening 96 in the panel 95, and the stopper member 41. The press-fit portion 43 is press-fitted into the engagement groove portion 16 and the portion of the supported portion 15 where the tapered rib 18 is formed is press-fitted into the connector insertion opening 96, whereby the supported portion 15 and the stopper member 41 are It is in a state of being closely connected to each other without rattling. The stopper member 41 is sandwiched between the support portion 20 and the panel 95, and the panel 95 is sandwiched from above and below by the stopper member 41 and the tapered rib 18 of the supported portion 15. The panel 95 is supported and does not move up and down with respect to the panel 95. Further, since the supported portion 15 is press-fitted into the connector insertion opening 96 by the taper rib 18, the housing 11 is supported by the panel 95 and does not move in the lateral direction, that is, the direction parallel to the panel 95. . If the coordinate axis of the plane parallel to the panel 95 is XY and the coordinate axis perpendicular to the panel 95 is Z, the housing 11 does not move relative to the panel 95 in any of the three XYZ directions. Thereby, the panel 95 can receive the external force received by the connector 1, and the external force can be reliably prevented from being transmitted to the substrate 91.

  Further, when the press-fitting of the stopper member 41 into the engaging groove portion 16 is completed, the locking projection 47 of the locking arm portion 46 is locked to the locking recess 17 as shown in FIGS. The member 41 is locked. Therefore, the stopper member 41 is not pulled out from the engaging groove portion 16 and is not detached from the housing 11.

  Next, an operation for fitting the mating connector 101 to the connector 1 will be described.

  18 is a perspective view showing a state before the mating connector is fitted to the connector according to the embodiment of the present invention, and FIG. 19 is a perspective view showing a state after the mating connector is fitted to the connector according to the embodiment of the present invention.

It is installed. Further, a housing recess for housing the terminal protection projection 26 is formed on the fitting end surface.

  In addition, a positioning groove 114 and a reverse prevention groove 115 as guide grooves extending in the insertion / extraction direction of the mating connector 101 are formed on the surface of the convex portion 112 facing the inner surface of the fitting opening 23. . Further, an engagement lever 121 having an engagement hole 121 a that engages with the connector engagement protrusion 22 is rotatably attached to the side surface of the housing 111.

  Then, the counterpart connector 101 is positioned above the connector 1 as shown in FIG. In this case, the fitting end surface of the convex portion 112 corresponds to the fitting opening 23, and the positioning groove 114 and the reverse prevention groove 115 face the corresponding positioning protrusion 24 and the reverse prevention protrusion 25. The posture of the counterpart connector 101 is controlled.

  Subsequently, the mating connector 101 is lowered relative to the connector 1, and the convex portion 112 is inserted into the fitting opening 23 provided in the housing 11 of the connector 1. In this case, the positioning groove 114 and the reverse prevention groove 115 of the mating connector 101 are engaged with the corresponding positioning protrusion 24 and the reverse prevention protrusion 25 of the connector 1. Thereby, positioning of the convex part 112 of the other party connector 101 with respect to the opening 23 for fitting with which the housing 11 of the connector 1 is provided is performed.

  And after engaging the engagement hole 121a of the engagement lever 121 with the connector engagement protrusion 22 with which the housing 11 of the connector 1 is provided, the engagement lever 121 is rotated so that the posture shown in FIG. . As a result, the convex portion 112 of the mating connector 101 is inserted to the back of the fitting opening 23 of the connector 1, the terminal protection convex portion 26 of the connector 1 is accommodated in the accommodating recess of the mating connector 101, and the connector 1 The contact portion 64 of the terminal 61 is inserted into the insertion port of the counterpart connector 101 and comes into contact with the counterpart terminal. Thus, the mating of the mating connector 101 to the connector 1 is completed, the mating connector 101 and the connector 1 are electrically connected, and the conductive cable 191 is electrically connected to the corresponding conductive trace of the board 91.

  When the mating connector 101 is fitted to the connector 1, a pressing force or other force is applied from the mating connector 101 to the connector 1, that is, not only the Z-axis direction force but also the X-axis direction and the Y-axis direction. However, as described above, the connector 1 is supported by the panel 95 and does not move relative to the panel 95 in any of the XYZ triaxial directions. These forces are received by the panel 95 and are not transmitted to the board 91 on which the connector 1 is mounted.

  Thus, in the present embodiment, the connector 1 includes the supported portion 15 that is inserted into the connector insertion opening 96 formed in the panel 95 and the engagement groove portion 16 that is formed on the outer surface of the housing 11. . Then, a part of the stopper member 41 is press-fitted into the engaging groove part 16, thereby moving the housing 11 and a part of the supported part 15 is press-fitted into the connector insertion opening 96. Accordingly, the connector 1 is supported by the panel 95 so that there is no rattling between the housing 11 and the panel 95 and the housing 11 does not move relative to the panel 95 in any of the three XYZ directions. Is done. Therefore, since the panel 95 receives the external force received by the connector 1, it is possible to reliably prevent the external force from being transmitted to the substrate 91, and to prevent damage to the substrate 91 and soldered portions of the terminals 61 and 91. It can be prevented from being damaged.

  Further, when the stopper member 41 is moved in a direction orthogonal to the direction in which the supported portion 15 is inserted into the connector insertion opening 96 and press-fitted into the engaging groove portion 16, a part of the supported portion 15 is supported by the supported portion 15. Is inserted into the connector insertion opening 96 by being moved in the insertion direction. Therefore, the stopper member 41 can be press-fitted into the engaging groove portion 16 and the supported portion 15 can be press-fitted into the connector insertion opening 96 by a simple operation by simply moving the stopper member 41, and the operation is facilitated.

  Further, in the stopper member 41, the taper rib 44 is press-fitted into the engagement groove portion 16, and in the supported portion 15, the taper rib 18 is press-fitted into the connector insertion opening 96. Thus, since the taper rib 44 and the taper rib 18 having a small contact area are press-fitted into the engagement groove portion 16 and the connector insertion opening 96, the force required for press-fitting can be reduced. Therefore, the work for press-fitting the stopper member 41 into the engaging groove portion 16 and press-fitting the supported portion 15 into the connector insertion opening 96 can be easily performed with a small force.

  Furthermore, the connector 1 is fixed and supported by the panel 95 by sandwiching the peripheral portion 95a of the connector insertion opening 96 in the panel 95 by the stopper member 41 and the tapered rib 18 of the supported portion 15. Therefore, since the connector 1 does not move relative to the panel 95 in any of the three XYZ directions, the panel 95 receives the external force received by the connector 1 and ensures that the external force is transmitted to the substrate 91. Can be prevented.
