Description

[Detailed Description of the Invention] The present invention relates to a socket with a connector for a vehicle lamp.

Among vehicle lamps, rear combination lamps for automobiles are configured to have at least two light chambers, such as a light chamber for a tail lamp and a stop lamp, a light chamber for a turn signal lamp, and a light chamber for a back lamp. ing. In such lamps, the bulbs installed in each lamp chamber are
The socket that holds this bulb and the cord that connects each socket make up an integrally wired harness, but if the vehicle body side panel extends between each light chamber, it is difficult to attach the light to the vehicle body. becomes a hindrance. Therefore, wiring to one of the lamp chambers separated by the overhang of the vehicle body side panel is performed after the lamp is attached to the vehicle body.

FIGS. 1 and 2 show two examples of the above-mentioned cases.

In FIG. 1, a lamp housing a includes a body part s forming a light chamber for a turn signal lamp, a body part u forming a light chamber for a back lamp, and a body part v forming a light chamber for a tail and stop lamp. It is molded into one piece,
An orange lens b ₁ is placed on the body part s, a white lens b ₂ is placed on the body part u, and a red lens b ₃ is placed on the body part v.
are integrally molded to form the front lens b. Further, on the vehicle body side panel k, an overhanging portion j is interposed between body portions s and u. Therefore, the valve d disposed within the body part s is connected to the connector i via the socket g and the cord h, and then to the power supply side connector y. on the other hand,
Valves e and f disposed within body parts u and v are
It is connected to a common connector 1 through each socket and cords t ₁ and t ₂ and then to a power supply side connector y.

By doing this, even if the overhanging part j of the vehicle body side panel k protrudes between the body parts s and u, the lamp can be handled as an integral assembly until it is attached to the vehicle body side panel. I can do it. However, when attaching to the vehicle body, the connector i and the cord h must be inserted into the panel hole m, and especially when the cord h is relatively long, it may get caught in the panel. Furthermore, when connecting the connector i to the connector y, the operator must use both hands, which causes a disadvantage in that work efficiency is significantly reduced in a narrow trunk room.

FIG. 2 shows another example of the prior art, in which a harness including a bulb to be disposed in each lamp chamber is formed in advance as an integrated wiring structure. In the figure, parts similar to those in FIG. 1 are indicated by the same reference numerals. That is, until the lamp is attached to the vehicle body side panel, the bulb d to be disposed inside the body part s is temporarily fixed (indicated by a chain line) to the temporary fixing part A provided in the lamp housing a, and then After attaching the lamp to the panel, move the bulb d from the temporary fixing part A in the direction of arrow P, insert it into the body part s through the panel hole m, fit the socket g, and then connect the cords h, t ₁ , t. Connect connector n connected to ₂ to power supply side connector y. In addition, in the figure, b ₄ is a retroreflective lens integrally molded with the front lens b.

By doing this, similar to Figure 1,
Even if there is an overhang j, the harness including the bulbs disposed in each light chamber can be treated as an integrated wiring structure in advance, but this also poses a difficulty in the installation work. That is, in order to move the bulb d and fit the socket g after attaching the lamp to the vehicle body, the locking protrusions r, r of the socket g must be inserted into at least two notches (not shown) formed in the body part s. ), it is necessary to rotate the socket g after pushing it in, but this notch is difficult to see after the light fixture is installed on the car body, so the operator has to fit the socket g by feeling, which reduces work efficiency. At the same time, the vibration of the valve d due to the incomplete fitting of the socket g caused the wire to break.

This invention was made in view of the above circumstances, and 2.
A vehicle light that can be reliably and easily connected to a power source, etc. even when the vehicle body side panel extends between the light chambers, is easy to assemble, and has a stable elastic contact force with the bulb. The purpose of this invention is to provide a socket with a connector.

Embodiments of the present invention will be described below with reference to FIGS. 3 to 6.
