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, rear combination lamps for automobiles have 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,
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, it is electrically connected to the connector i via the valve d, the socket body g and the cord h disposed within the body part s, and is 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 a common connector l through the respective socket bodies and cords t ₁ and t ₂ , and are connected to the power supply side connector y in the same manner as described 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 that work efficiency is significantly reduced.

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 bottom part s. This is used to rotate the socket body g, but this notch is difficult to see after the light is installed on the vehicle body.
Therefore, the operator must 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> This invention was made in view of the above circumstances.
To provide a socket body with a connector for a vehicle lamp, which can be surely and easily connected to a power source, etc. even when a vehicle body side panel extends between at least two light chambers.

<Structure of the invention> In order to achieve the above object, the present invention provides a cylindrical metal socket in which a notch is formed in the cylindrical portion that locks the valve cap and a negative electrode connection piece is integrally formed, and the socket is assembled into a cylindrical metal socket. a synthetic resin holder which integrally forms a storage part and a connector part to be stored and fixed and has two holes communicating from the storage part to the connector part; A positive electrode terminal that passes through the notch of the metal socket and comes into elastic contact with the valve eyelet, and the other end is a positive electrode connection piece, and an insulating piece that is integrally molded with the synthetic resin holder via a thin hinge. The negative electrode connecting piece and the positive electrode connecting piece are respectively inserted into the hole from the storage portion and arranged in the connector portion, and the negative electrode connecting piece and the positive electrode connecting piece are inserted between the notch of the metal socket and the positive electrode terminal. This is a socket body with a connector for a vehicle lamp characterized by having an insulating piece interposed therebetween.

<Embodiment of the invention> Hereinafter, FIGS. 3 to 8, which are embodiments of the invention, will be described. Fig. 3 shows an example of a socket body with a connector of the vehicle lamp of the present invention attached to a rear combination lamp of an automobile, where 1 is a lamp housing and a body part 1a forming a lamp chamber for a tail lamp and a stop lamp.

In addition, when replacing the bulb 32 with the mating connector 4a connected to the connector part 68, that is, when the connection is made on the power supply side, when the bulb 32 is removed from the socket 7, the positive terminal The end piece 81 of 8 is resiliently displaced upward, but along with this displacement, the insulating piece 63 is pushed into the socket 7.
No shortening occurs due to contact with the upper end of the notch 78.

Finally, with the socket body 5 with the bulb 32 inserted therein attached to the body portion 1b, the lamp is attached to the vehicle body panel k, as shown in FIG. Then, the mating connector 4a is connected to the connector portion 68 of the socket body 5 in the direction of arrow T, and the lamp assembly is completed.

<Effects of the invention> The socket body with a connector of the present invention has a holder that integrates the socket storage part and the connector part, and by fitting the socket with the negative electrode connecting piece integrally formed and the positive electrode terminal, the inside of the connector part can be removed. Since the positive and negative electrode connecting pieces are arranged in the connector, it is easy to assemble the socket body, and the number of parts is small, which improves assembly work efficiency and reduces costs. Since no other member is involved in the connection, the voltage drop can be reduced. Furthermore, since such a socket body with a connector can be attached to the body of the lamp in advance, the mating connector can be connected with one hand when attached to the vehicle body, and it is also possible to connect an incomplete socket body to the body part as in the past. This has the effect of preventing attachment.
