[Problems to be solved by the device]

 However, in the above-described conventional vehicular lamp, since the connectors 4 and 9 must be connected while the lamp 2 is held, the work is troublesome and the burden on the operator is large, and the lamp 2 itself. However, even if the attachment to the vehicle body 1 can be automated, there is a problem that the connectors 4 and 9 cannot be automated until the connectors 4 and 9 are connected because the connectors 4 and 9 hang down in the vehicle body 1. Therefore, as a method of solving such a problem, as shown in, for example, Japanese Utility Model Laid-Open No. 55-69311, Japanese Utility Model Laid-Open No. 54-39852, the connector on the lamp side is fixed in advance on the back side of the lamp to fix the lamp. Various types have been proposed in which the connector on the lamp side and the connector on the vehicle body side are connected when assembled to the vehicle body. However, in all of these types, there is a restriction that the mounting and removal direction of the lamp is uniquely determined by the connection direction of the connectors, and in both cases, the lamp side connector is rigidly fixed to the back of the lamp. Therefore, it was not possible to absorb the positional deviation between the connectors in the left-right and up-down directions, which was a major obstacle in adopting automatic assembly. Further, there is a problem that the connectors are easily detached due to vibration or the like because the connectors are simply fitted and connected to each other in the past.

Therefore, the present invention has been made in view of the above-mentioned conventional problems, and the purpose thereof is to attach and detach the lamp to and from the vehicle body, and to connect the lamp side connector and the vehicle body side connector. An object of the present invention is to provide a vehicular lamp that is easy to connect and disconnect, enables automatic assembly of the lamp to the vehicle body, saves labor, and prevents the connector from being easily disconnected due to vibration or the like.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a vehicle body side connector fitted and fixed in a connector insertion hole of a vehicle body, and a lamp side connector connected to the vehicle body side connector is disposed on the rear side of the lamp body. A locking arm is provided on either one of the connector and the lamp side connector, and an arm locking part for locking this locking arm is provided on the other side, and the lamp side connector is fitted and held in the connector holding part provided on the rear surface of the lamp. The fitting direction and the connecting direction of the both connectors are orthogonal to each other.

[0006]

[Action]

 In the present invention, the vehicle body side connector is fitted and fixed in the connector insertion hole of the vehicle body to facilitate the connection of the lamp side connector. Further, since the fitting direction of the vehicle body side connector and the lamp side connector and the fitting direction of the connector fitted into the connector holding portion are orthogonal to each other, when the lamp body is removed from the vehicle body, the lamp body side connector is Never fall off. The locking arm and the arm locking portion are engaged with each other, and the connector is locked to prevent separation due to vibration or the like.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. 1 is a partially cutaway perspective view showing an embodiment of a connector and a connector holding portion, FIG. 2 is a partially cutaway sectional view of a vehicle lamp having a turning portion, and FIG. 3 is a perspective view of the connector holding portion. 4 is an exploded view of the fastener and the stud pin. In the figure, the same components as those in FIG. 7 are designated by the same reference numerals and the description thereof will be omitted. In FIG. 2, in the present embodiment, the lamp side connector 4 is detachably fitted and arranged in a connector holding portion 21 integrally provided on the back surface of the lamp 2, and the vehicle body side connector 9 is inserted into the connector insertion hole 3 of the vehicle body 1 in the vehicle body. It is detachably attached from the outside front side, the lamp side connector 4 is connected to the vehicle body side connector 9 from the vehicle body front side, the fasteners 6 and 22 and the stud pins 7 and 23 are respectively engaged, and further by a set screw (not shown). The lamp 2 is fixed to the corner of the vehicle body 1 and is detached to the side of the vehicle body when detached. Reference numeral 20 denotes a sheet packing interposed between the vehicle body 1 and the lamp 2, an arrow A direction indicates a mounting direction of the lamp 2, and an arrow B direction indicates a removing direction.

As shown in FIG. 2, the lamp 2 constitutes a combination lamp by incorporating a plurality of kinds of lamps into one lamp body 24, and the inside is partitioned into, for example, three lamp chambers 25A to 25C. The lamp body 24 and the front lens 26 that hermetically covers the front opening of the lamp body 24. The lamp chamber 25A located at the center has, for example, a tail-and-stop lamp bulb 27 and a tail-and-stop lamp. The lamp chamber 25B on the left side has a backup lamp bulb 29 to form a backup lamp 30, and the lamp chamber 25C on the right side wraps around the side surface 1A of the vehicle body and has a turn signal lamp bulb 31. The signal lamps 32 are formed respectively.

The front lens 26 includes a first lens 26A that covers the lamp chamber 25A, a second lens 26B that covers the lamp chamber 25B, and a third lens 26C that covers the lamp chamber 25C. The lens 26A is colored red, the second lens 26B is colored white, and the third lens 26C is colored amber. As described above, since the front lens 26 is formed so that the colors of the first, second and third lenses 26A, 26B and 26C are different from each other, it is impossible to perform simultaneous molding with a mold, and thus it is well known that many lenses are conventionally known. It is integrally manufactured by the color molding method. A retroreflector 33 that retroreflects external light from the rear in the same direction as the incident direction is provided at the center of the surface of the first lens 26A.

In FIG. 1, the lamp-side connector 4 forms a female connector, and is provided with a rectangular parallelepiped resin connector body 41. Inside the connector body 41, the terminals 42 of the vehicle-body-side connector 9 are provided. A plurality of terminals (not shown) to be fitted and connected are provided, and one end of the lamp side cord 8 is connected to each of these terminals. Engagement grooves 44 and 45 are formed on the upper and lower surfaces of the connector body 41 over the entire length in the width direction, and a locking arm 46 is integrally provided on one vertical side surface. Ends of the engaging grooves 44 and 45 on the connector holding portion 21 side are formed in a taper shape that widens toward the connector holding portion 21 side, and opposite end portions of the engaging grooves 44 and 45 are locking recesses 48 that are one step deeper. The locking arm 46 is T-shaped in a plan view of the connector, and includes an elastically deformable base portion 46A that is orthogonal to the side surface of the connector body 41, and a plate-like locking piece 46B that is orthogonal to the base portion 46A and extends in the front-rear direction. A triangular locking claw 49 is integrally formed on the inner surface of the tip of the locking piece 46B. The front end face of the connector body 41 is formed into a tapered trapezoid to facilitate fitting with the vehicle-body-side connector 9.

The vehicle-body-side connector 9 forms a male connector and has a rectangular parallelepiped resin main body 50 larger than the lamp-side connector 4, and has a front surface to which the lamp-side connector 4 can be fitted. A concave portion 51 is provided, and the terminal 42 is arranged inside the concave portion 51. One end of the vehicle body side cord 10 is connected to each terminal 42. The opening of the fitting recess 51 is a tapered hole 51a that widens outward, facilitating fitting of the lamp-side connector 4 1. On the outer peripheral surface of the rear end portion of the main body 50, a plurality of elastic engagement pieces 53 for locking the vehicle body side connector 9 in the connector insertion hole 3 of the vehicle body 1 are integrally projected. These elastic engagement pieces 53 absorb the assembly error of both connectors 4 and 9 by elastically deforming in the direction of approaching and separating from the main body 50 when connecting the lamp side connector 4 to the vehicle body side connector 9, Secure the connection of both connectors. An arm locking portion 54 is formed on one side surface of the main body 50 so as to correspond to the locking arm 46. The arm locking portion 54 is composed of a hole or a recess communicating with the fitting recess 51, and the locking claw 49 of the locking arm 46 engages when the lamp-side connector 4 is connected to the vehicle body-side connector 9. Then, the lamp side connector 4 is locked together with the locking arm 46 to prevent the lamp side connector 4 from being separated from the vehicle body side connector 9 due to vibration or the like.

The connector holding portion 21 that houses and holds the lamp-side connector 4 is integrally provided on the rear surface of the lamp body 24 so as to project rearward, and the rear surface and the detaching direction of the lamp 2 (direction of arrow B in FIG. 2). By presenting a box type (FIGS. 1 and 3) in which the opposite side surface is open, the vertical plate 21A and the upper and lower plates 21B and 21C facing each other vertically are formed. Protrusions 56 and 57 that engage with the engaging grooves 44 and 45 of the lamp-side connector 4 are provided at the open end of the rear end edge. The distance D between the protrusions 56 and 57 is set to be slightly smaller than the distance D1 between the bottom surfaces of the engagement grooves 44 and 45. Therefore, when the lamp-side connector 4 is inserted into the connector holding portion 21, the rear end sides of the upper and lower plates 21B and 21C are elastically deformed vertically to allow the engagement grooves 44 and 45 and the protrusions 56 and 57 to engage with each other. When the lamp side connector 4 is completely housed in the connector holding portion 21, the protrusions 56 and 57 correspond to the locking recesses 48 of the engaging grooves 44 and 45, and the upper and lower plates 21B and 21C elastically return. By fitting in the locking recess 48, the lamp-side connector 4 is prevented from coming off the connector holding portion 21. The rear end portion of the lamp-side connector 4 projects rearward from the rear-side opening of the connector holding portion 21 to enable fitting with the vehicle-body-side connector 9. Since the connecting direction of the lamp side connector 4 and the vehicle body side connector 9 is the arrow A direction, when the lamp 2 is moved in the arrow B direction and detached from the vehicle body 1, the lamp side connector 4 remains in the vehicle body side connector 9. , It comes out from the connector holding portion 21.

2 and 4, the fastener 6 for fixing the wrap-around portion 2A of the lamp 2 to the vehicle body side surface 1A has a fitting hole 60 into which the stat pin 7 can be fitted by being formed in a tubular shape. However, it is press-fitted and fixed in a fastener mounting hole 61 provided in the vehicle body side surface 1A. The stud pin 7 has two flange portions 63A and 63B that are integrally provided with the base end portion 62 interposed therebetween, and is detachably attached to the back surface of the wraparound portion 2A of the lamp 2 via a mounting bracket 64. ing. The pin holding portion 64A of the mounting bracket 64 is substantially parallel to the vehicle body side surface 1A and has a key-shaped locking hole 65 that opens at the rear end, and the base end portion 62 is inserted into the inner portion of this locking hole 65. By doing so, the stud pin 7 is held.

In this case, since the engaging direction of the fastener 6 and the stud pin 7 (the direction opposite to the arrow B direction in FIG. 2) is orthogonal to the mounting direction of the lamp 2 to the vehicle body 1 (arrow A direction), When installing the stud pin 7, the stud pin 7 is inserted into the fastener 6 in advance, and when the lamp 2 is fitted into the corner portion of the vehicle body 1 from the front in this state, the locking hole 65 engages with the base end portion 62 of the stud pin 7. To meet. On the other hand, when the lamp 2 is removed, if the lamp 2 is moved in the direction of arrow B in FIG. 2, the stud pin 7 is removed from the fastener 6 while being held by the mounting bracket 64, and the lamp 2 can be removed.

The fastener 22 and the stud pin 23 for fixing the end portion of the lamp 2 on the side opposite to the wraparound portion 2 A to the vehicle body 1 have the same structure as the fastener 6 and the stud pin 7 described above. A stud pin 23 is removably attached to the rear surface of the left end of FIG. 2 of the lamp 2 through a mounting bracket 70 while being fixedly press-fitted into a fastener mounting hole (not shown) provided in the lamp. The stud pin 23 is attached so as to be orthogonal to the stud pin 7, and is pressed into the fastener 22 from the direction of arrow A, and when the lamp 2 is moved in the direction of arrow B, the mounting bracket 70 separates from the stud pin 23. The direction of engagement and disengagement between the fastener 6 and the stud pin 7 and the direction of engagement and disengagement between the stud pin 7 and the mounting bracket 64 are different. Therefore, when the lamp 2 is attached, the stud pin 23 is previously attached to the mounting bracket 70, and when the lamp 2 is fitted into the corner portion of the vehicle body 1 from the front in this state, the stud pin 23 is press-fitted into the fastener 22, When the lamp 2 is moved in the direction of the arrow B in FIG. 2 when the lamp 2 is removed, the mounting bracket 70 is disengaged from the stud pin 23, and the stud pin 23 remains on the fastener 22 so that the lamp 2 can be removed.

Thus, in the vehicular lamp having such a configuration, the vehicle-body-side connector 9 is mounted in the connector insertion hole 3 by the elastic engagement piece 53 while allowing a slight movement in the vertical and horizontal directions. By absorbing the positional deviation between the lamp-side connector 4 and the vehicle-body-side connector 9 (the strictness of alignment between the connectors is not required), the connectors can be securely connected to each other, which facilitates the assembly by the automatic assembly machine. To do. Further, since the lamp side connector 4 is locked to the vehicle body side connector 9 by the engagement of the locking arm 46 and the arm locking portion 54, there is no fear that the lamp side connector 4 will come off the vehicle body side connector 9 due to some vibration. , Maintain a secure connection. Furthermore, since the connecting and disconnecting directions of the lamp side connector 4 and the vehicle body side connector 9 are the directions orthogonal to the removing direction of the lamp 2, the lamp side connector 4 is disconnected from the vehicle body side connector 9 when the lamp 2 is removed. There is no risk of falling out.

FIG. 5 is a cross-sectional view of a main part showing another embodiment of the present invention, and FIG. 6 is a perspective view of a lamp side connector and a vehicle body side connector. In this embodiment, the vehicle body side connector 9 is fitted in the fitting concave portion 79 of the lamp side connector 4, and the connector insertion hole 3 of the vehicle body 1 to which the vehicle body side connector 9 is attached is directly sealed by the packing 80, as shown in FIG. The seat packing 20 is omitted.

On the outer peripheral surface of the lamp-side connector 4, a flange 82 that fits into an annular groove 81 formed on the inner periphery of the packing 80 is integrally projected. On the outer peripheral surface of the rear end portion of the vehicle body side connector 9, an arm locking portion 83 is integrally provided so as to correspond to the locking arm 46 of the lamp side connector 4, and a stopper 84 of the lamp side connector 4 is also protruded. There is. The locking arm 46 is formed in a plate shape extending rearward of the connector 4 on the lamp side, and a triangular locking claw 49 is integrally projectingly provided on the outer surface of the tip end portion and inserted into the hole 85 of the arm locking portion 83. By being locked, the lamp-side connector 4 is locked. The rest of the configuration is similar to that of the above-described embodiment. Even with such a configuration, the same effect as that of the above embodiment can be obtained.

In each of the above embodiments, the locking arm 46 is provided on the lamp side connector 4 and the arm locking portion 54 (83) is provided on the vehicle body side connector 9, but the reverse order is also possible.
