Abstract

(57) [Abstract] [Purpose] In a conventional vehicular lamp of a type in which electric power is supplied via a coupler and a cord, the coupler and the coupler are formed on the housing without using means such as integral molding. By integrating the above, the complexity of the assembly process associated with the conventional method is eliminated and the number of parts is reduced. [Structure] The housing-integrated coupler structure according to the present invention comprises a housing 2, a coupler 4, an O-ring 3, a sealant, and an adhesive. Unlike the housing 2, the coupler 4 is made of a material having excellent heat resistance and dimensional stability. Further, the O-ring 3, the sealing material, and the adhesive material are interposed between the housing 2 and the coupler 4,
It is used to bring the two into close contact with each other to ensure the sealing property.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicular lamp such as a high mount stop lamp, and more particularly to an integrated structure of a housing and a coupler of the vehicular lamp.

[0002]

[Prior art]

 FIG. 4 shows an example of the configuration of a conventional vehicle lamp 90 of this type. A cord 92 is pulled out from the housing 91, and a coupler 93 is attached to the tip of the cord 92. . Further, a grommet 94 is fitted to a portion where the cord 92 penetrates the housing 91 to waterproof the inside of the housing 91.

Therefore, when the coupler 93 is attached to the vehicle lamp 90, a cord 92 connected to, for example, a socket or a printed circuit board is pulled out from the housing 91, and the grommet 94 is passed through the cord 92 to allow the housing 91 and the grommet 9 to pass through. 4 is fitted and then the coupler 93 is attached to the tip of the cord 92.

[0004]

[Problems to be solved by the device]

 However, in the above-mentioned conventional configuration, the assembly process is very complicated, and automation is also difficult, so that all of them have to rely on human hands, which causes a problem of lowering production efficiency. There is.

If the coupler 93 is formed integrally with the housing 91, the above-mentioned problem can be solved by omitting the cord 92 and the assembling of the housing 91 and the grommet 94. Formability is important for the formed member, and heat resistance is low and dimensional stability is not sufficient, so it was difficult to adopt an integral molding method.

[0006]

[Means for Solving the Problems]

 As a concrete means for solving the above-mentioned problems, the present invention provides a coupler structure for a vehicle lamp provided for connecting to an external power source, wherein an opening is provided in a housing of the vehicle lamp. By providing a coupler housing formed of a member different from the housing to this opening to integrally integrate the lamp and the coupler, the conventional problem is solved by providing a coupler structure for a vehicle lamp. It is a solution.

【Example】

 Next, the present invention will be described in detail based on the embodiment shown in the drawings. 1 is an exploded view of a first embodiment of a vehicular lamp according to the present invention, and FIG. 2 is a sectional view of the same embodiment in an assembled state. In this embodiment, the housing 2 and the coupler housing 4 are coupled to each other with an O-ring 3 interposed in an opening 2a provided in the housing 2. Here, the O-ring 3 is used to bring the housing 2 and the casing 4 into close contact with each other to ensure a sealing property therebetween.

The housing 2 and the coupler housing 4 are formed so as to be mechanically engaged with each other by an appropriate engaging means such as a hook 4a, and the O-ring 3 is compressed by this engaging. In other words, the elasticity of the O-ring 3 allows the housing 2 and the casing 4 to be held in engagement with each other, and a special engagement means can be eliminated.

Further, in the above configuration, the terminal 5 is directly connected to, for example, the print substrate in the housing 2 to be desired in the opening 2a, and thus the terminal 5 is used in the conventional example. No code is required.

With the above configuration, the housing 2 and the coupler housing 4 can be integrated, and each can be formed individually. Therefore, for forming the housing 2, for the housing 2, for example, an optimum resin material can be selected in terms of moldability, and also for the coupler housing 4, an optimum resin material can be selected in terms of dimensional retention. Will be things.

FIG. 3 shows a second embodiment of the vehicular lamp according to the present invention. In this embodiment, the housing 2 and the coupler housing 6 are joined by an adhesive 7 which also serves as a seal. The point that the coupler housing 6 can be made of a material different from that of the housing 2 that has excellent heat resistance and can secure dimensional stability, and that the housing 2 and the coupler housing 6 are mechanically anchored in advance by a hook structure or the like, This is similar to the case of the first embodiment. In addition, when the sealing property is not required between the housing and the coupler housing such as when mounting the lamp in a vehicle, the O-ring is omitted in the first embodiment, and the second embodiment is omitted. In that case, the sealing material and the adhesive material are omitted.

[0012]

[Effect of device]

 As described above, according to the present invention, the coupler of the vehicular lamp is made of a material different from that of the housing, and the coupler is utilized by using a mooring mechanism such as a hook and an O-ring, a seal material or an adhesive material is also used. By integrating the housing and the coupler, the housing and the coupler can be integrated without being affected by dimensional changes due to high temperatures. This allows the cord to pass through the grommet and the coupler in the conventional technology. It is possible to omit complicated steps such as fixing and to effectively improve the production efficiency.
