Description

[Detailed Description of the Invention] <Technical Field of the Invention> The present invention relates to a socket with a connector for use in a vehicle lamp.

<Prior art and its problems> Among vehicle lamps, a rear combination lamp for an automobile has at least three light chambers, including 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 rear lamp. It is configured to have a light chamber. Such lighting equipment consists of a bulb installed in each lamp chamber, a socket body that holds the bulb, and a harness that is integrally connected with a cord that electrically connects each socket body. However, if the vehicle body side panel on which the lamp is attached is shaped to protrude between the respective light chambers, it becomes an obstacle when attaching the lamp to the vehicle body. 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.

That is, 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,
Body part s has an orange lens b ₁ , body part u has a white lens b ₂ , body part v has a red brick b ₃
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 electrically connected to the connector i via the socket body g and the cord h, and further connected to the power supply side connector y. On the other hand, the valves e and f disposed in the body parts u and v are connected to each socket body and the cords t ₁ and t _{2 .}
It is connected to the common connector 1 via , and connected to the power supply side connector y in the same way as above.

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. Connector i and connector y are connected after installation on the vehicle body. 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 k. Furthermore, when connecting connector i to connector y, the operator must use both hands. Particularly in the case of a narrow trunk room, this has the disadvantage of significantly reducing work efficiency.

FIG. 2 shows another example of the conventional one, in which a harness including a bulb disposed in each lamp chamber is configured 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 dotted line) to the temporary fixing part A provided in the lamp housing a, and then Immediately after attaching the lamp to the panel, move the bulb d from this temporary fixing part A in the direction of the dotted arrow P, and move the bulb d to the panel hole m.
Insert it further into the body part s, and insert the socket body g
Insert. After that, the connector n connected to the cords h, t ₁ and t ₂ is connected to the power supply side connector y. In the figure, b ₄ is a retroreflective lens integrally molded with the front lens b.

By doing this, similar to Figure 1,
Even with the overhang j, it is possible to form the harness including the bulbs disposed in each lamp chamber in advance as an integrated wiring structure, but this also has difficulties in the installation work. That is, when fitting the socket body g with the movement of the bulb d after the lamp is mounted on the vehicle body, the locking protrusions r and r are pushed in so as to face at least two notches (not shown) formed in the body part s. However, after the lamp is attached to the vehicle body, this notch is difficult to see, so the operator has to fit the socket body g by feeling. Therefore, work efficiency is significantly reduced, and incomplete fitting of the socket body g tends to cause the socket body g to fall off or the valve d to break due to vibrations during traveling. Furthermore, since the bulb d is temporarily fixed to the temporary fixing part A, there is a problem in that dust and the like tend to adhere to the inside of the body part s, causing problems in light distribution.

<Purpose of the invention> The present invention was made in view of the above circumstances, and is intended for use in vehicles that can be reliably and easily connected to a power source, etc. even when a panel on the vehicle body side extends between at least two light chambers. The purpose of this invention is to provide a socket with a connector for a lamp.

<Structure of the invention> In order to achieve the above object, the present invention provides a synthetic resin socket body in which a flange and a locking protrusion for mounting the lamp body are formed, and a housing part for a valve cap and a connector part are integrally formed. , positive and negative terminals arranged in the connector part, and first terminals arranged inside and outside the wall formed in the storage part.
A coil spring and a second coil spring are provided, and in a state where the locking pin of the valve cap is locked in the locking groove formed on the inner wall of the storage portion, the valve eyelet and the positive terminal are connected to the first coil spring. This connector-equipped socket for a vehicle lamp has a structure in which the bulb cap and the negative terminal are electrically connected by elastic contact of the second coil spring.

<Embodiment of the invention> Hereinafter, FIGS. 3 to 5, which are embodiments of the invention, will be described. Figure 3 shows an example in which the socket with connector of the vehicle lamp of the present invention is attached to a rear combination lamp, in which 1 shows the lamp housing, the body part 1a forming the lamp chamber for the tail lamp and the stop lamp, and the turn signal lamp. body part 1b forming a lamp chamber for

In addition, saw-blade-shaped locking portions 71e are formed on both side edges of the terminal 7e, and the locking portions 71e are fixed by being inserted into the connector portion 57 from the storage portion 50 in the same manner as described above.

<Effects of the invention> As mentioned above, the socket with a connector of the invention can be easily assembled by simply fitting a pair of terminals and two coil springs into the socket body, and the number of parts is small and assembly work efficiency is improved. In addition, the two coil springs allow reliable electrical connection, and it is possible to easily obtain an appropriate holding pressure for the locking pin of the valve. In addition, by attaching such a socket with a connector to the body of the lamp in advance, it is possible to connect the other connector with one hand, and furthermore, it is possible to prevent incomplete socket attachment to the body part as in the case of the conventional method. It is something to play.
