In particular, the present invention relates to a vehicular lamp capable of reliably and easily connecting a lamp-side connector and a power-source-side connector in a narrow space by preventing the lamp-side connector from being erroneously assembled or rotated.

[Prior Art] A conventional vehicular lamp of this type will be described with reference to Figs. 4 to 6.

In the drawing, reference numeral 1 denotes a lamp body such as a backup lamp, and the lamp body 1 includes a housing 10, a lens (outer lens) 11 arranged in a front opening of the housing 10, the housing 10 and the circumference of the lens 11. And a rim 12 disposed on the side of the housing 10 and a light source bulb (not shown) removably attached to the center of the rear portion of the housing 10 in a lamp chamber (not shown) defined by the housing 10 and the lens 11. And a socket 13 arranged at a position.

Reference numeral 2 is a power cord electrically connected to the socket 13 of the lamp body 1.

3 is a connector on the side of the lamp which is electrically connected to the power cord 2, and the connector 3 on the side of the lamp is detachably mounted and electrically connected to a connector on the side of the power source (vehicle body) not shown on the front end face side. Is configured to.

Reference numeral 4 denotes a fixing portion integrally provided on the rear portion of the housing 10 of the lamp body 1 adjacent to the socket 13, and the fixing portion 4 has a rib shape and is parallel to the connecting direction b of the power source side connector. And the insertion hole 40 is provided at the upper end of the fixing portion 4.

Reference numeral 5 denotes a fixing clip integrally provided on a side surface of the lamp-side connector 3 near the rear portion. The fixing clip 5 has an insertion portion 50 protruding from the lamp-side connector 3 and an arrowhead shape at the tip of the insertion portion 50. The first elastic contact portion 51 is integrally provided, and the second elastic contact portion 52 is integrally provided in a bow shape at the base of the insertion portion 50.

Reference numeral 6 denotes a vehicle body panel as an attachment body of the lamp body 1, and an attachment hole 60 is provided in the vehicle body panel 6.

Thus, the first elastic contact portion 51 and the insertion portion 50 of the fixing clip 5 are inserted into the insertion holes 40 of the fixing portion 4. Then, the first elastic abutment portion 51 and the second elastic abutment portion 52 of the fixing clip 5 elastically abut on the peripheral edge portion of the insertion hole 40 of the fixing portion 4 from both front and back sides, and the fixing clip 5 is used to interpose the lamp. The side connector 3 is fixed to the fixing portion 4 on the side of the lamp body 1 while restricting movement of the fixing clip 5 in the inserting direction of the fixing clip 4 and in a direction orthogonal to the inserting direction.

Next, the lamp side connector 3, the fixing portion 4, the fixing clip 5, the power cord 2 and the rear portion (socket 13) of the lamp body 1 are fitted into the mounting holes 60 of the vehicle body panel 6 from the outside O of the vehicle to the inside of the trunk in a narrow space. The lamp body 1 is attached to the vehicle body panel 6 by inserting it in the direction T (the space between the outer vehicle body panel 6 and the panel (not shown) forming the inner luggage compartment) in the direction of arrow A in FIG.

Then, in the trunk T of the narrow space described above, the power source side connector is connected to the lamp side connector 3 in the direction of the arrow B in FIG. 6 to complete the electric wiring of the vehicle lamp.

In FIG. 6, when the vehicle body panel 6 is shown by a solid line, it shows a state before the lamp body 1 and the like are assembled to the vehicle body panel 6, while the vehicle body panel 6 is shown by a two-dot chain line. Shows a state after the lamp body 1 and the like are assembled to the vehicle body panel 6.

Here, the length of the power cord connected to the above-mentioned power source side connector is a length necessary for connecting to the lamp side connector 3 of the lamp body 1 attached to the vehicle body panel 6 due to a wiring problem in a narrow space. Since there is nothing else, the above-mentioned power source side connector cannot be connected to the lamp side connector 3 only in the direction of arrow B in FIG. Further, since the space inside the trunk T is very small and only one hand can be inserted into the trunk T, the electrical connection between the power supply side connector and the lamp side connector 3 is performed with one hand in the narrow space T inside the trunk. There must be.

As a result, in the above-described vehicle lamp, in order to reliably and easily perform the connecting work between the lamp side connector 3 and the power source side connector in the trunk T in the narrow space, the lamp side connector 3 and the power source side connector are It is important to control the connection direction of the lamp and to prevent the lamp-side connector 3 from rotating around the axis C whose axis is the insertion direction of the fixing clip 5 into the fixing portion 4.

[Problems to be Solved by the Invention] However, the above-described conventional vehicle lamp is not provided with means for regulating and positioning the connecting direction of the lamp side connector 3 to the power source side connector, so that the fixing clip 5 When fixing the lamp side connector 3 to the fixing part 4 by inserting the lamp into the insertion hole 40 of the fixing part 4, the direction of the lamp side connector 3 cannot be determined, and the direction of the lamp side connector 3 is different from the predetermined direction. The lamp-side connector 3 may be fixed to the fixing portion 4 in the direction. In particular, it is rare that the lamp-side connector 3 is fixed to the fixing portion 4 in a state in which the lamp-side connector 3 faces 180 degrees different from the predetermined direction, that is, the lamp-side connector 3 is erroneously assembled. If the lamp-side connector 3 is incorrectly assembled, it becomes impossible to connect the power-side connector to the lamp-side connector 3 in the direction of the arrow B in the trunk T in the above-mentioned narrow space. There is a problem that the electrical connection with the connector is not made securely.

Further, the above-described conventional vehicle lamp is not provided with a means for restricting the rotation of the lamp-side connector 3 about the axis of which the fixing clip 5 is inserted in the fixing portion 4 as the axis C. The first elastic contact portion 51 and the second elastic contact portion 52 of the fixing clip 5 elastically contact the peripheral edge of the insertion hole 40 of the fixing portion 4 from both sides, and the fixing clip 5 is inserted into the fixing portion 4. Direction and the movement in the direction orthogonal to the insertion direction are restricted, the lamp-side connector 3
Is in a state of being rotatable about the axis of the insertion portion 50 of the fixing clip 5. As a result, when connecting the power supply side connector to the lamp side connector 3, the lamp side connector 3 may rotate. For this reason, in the trunk T in a narrow space, it is necessary to perform the electrical connection work between the lamp side connector 3 and the power source side connector while preventing the lamp side connector 3 from rotating with one hand, which is complicated. I have a problem.

An object of the present invention is to provide a vehicular lamp capable of reliably and easily connecting the lamp-side connector and the power-source-side connector in a narrow space.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides an erroneous assembly prevention / rotation preventing portion in the lamp body and the fixing portion, and the erroneous assembly prevention / rotation preventing portion has a contact surface. Is provided, and when the fixing clip is inserted into the insertion hole of the fixing portion, it abuts the contact surface of the mis-assembly prevention / rotation preventing portion to regulate the connection direction of the lamp-side connector to the power-side connector and A contact surface that restricts rotation of the lamp-side connector around the axis of the clip insertion direction is provided on the lamp-side connector and the fixing clip, respectively.

[Operation] According to the present invention, when the fixing clip of the lamp-side connector is inserted into the insertion hole of the fixing portion of the lamp body with the above configuration, the contact surface of the lamp-side connector and the contact surface of the fixing clip are erroneously assembled. The lamp-side connector is abutted against the contact surface of the prevention / rotation preventing portion, the connection direction of the lamp-side connector with the power-side connector is restricted, and the lamp-side connector is provided around the axis around the insertion direction of the fixing clip. Is restricted from rotating.

Thus, when fixing the fixing clip of the lamp-side connector to the fixing portion of the lamp body, the direction of the lamp-side connector is determined to be a predetermined direction, and it is possible to prevent erroneous assembly of the lamp-side connector. Further, when the lamp-side connector and the power-source-side connector are connected, it is possible to prevent the lamp-side connector from rotating around its axis around the insertion direction of the fixing clip into the fixing portion. Therefore, it is possible to surely and easily perform the connecting work between the lamp side connector and the power source side connector in a narrow space.
