Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a waterproof cover for a vehicle lamp, and more particularly to a waterproof cover that prevents rainwater from entering the socket portion.

[Conventional technology]

For example, as a conventional waterproof cover,
The configurations described in Publication No. 2024 and Publication of Utility Model Publication No. 58-18161 are known.

[Problem that the invention attempts to solve]

The waterproof cover of Utility Model Publication No. 60-20242 mentioned above is
This configuration forms a ventilation path etc. in combination with the holding cap, and cannot be used with lamps that have different socket configurations or bulb mounting configurations. In addition, the waterproof cover in Japanese Utility Model Publication No. 58-18161 has a short ventilation path, and rainwater splashed by the wheels can enter the interior through the ventilation path, and the drainage hole is inappropriately located and shaped to prevent sufficient drainage. I ran into a problem where I couldn't get any results.

In addition, in order to provide a sufficiently long ventilation path in the conventional structure, the waterproof cover had to have a complicated shape, which caused the problem that molding using a mold was time-consuming.

[Means to solve the problem]

The waterproof cover consists of a generally conically inclined brim, a cylindrical hollow part, and a rectangular hollow bottom. A stepped portion that bulges inward is provided at the boundary between the two. Furthermore, a drainage hole is formed at the lower end of the hollow portion, and extends downwardly and has an opening on the side opposite to the back surface of the collar portion, and also has a drainage hole that communicates vertically along the side wall of the hollow bottom portion, and has an opening at the lower end. However, this device is characterized by a configuration in which a ventilation hole is formed in the upper end portion with an opening formed by cutting out a part of the side wall of the hollow bottom portion.

[Effect]

Rainwater that has entered between the collar and the lamp housing is prevented from entering the hollow section and the hollow bottom by the stepped section, and is easily discharged through the recess provided at the lower end of the collar. In addition, water droplets that have condensed inside are easily discharged through a drainage hole provided at the lower end of the hollow portion. In addition, ventilation and effective drainage are provided via ventilation holes and said drain holes which run from top to bottom along the side walls of the hollow bottom.

[Example] In Figs. 1 to 4, reference numeral 1 denotes a waterproof cover made of an elastic material such as rubber. It consists of a cylindrical hollow bottom part 4. A recess 2a for drainage is provided at the lower end of the collar 2, and a step 2b bulging inward is provided at the boundary between the collar 2 and the hollow portion 3. A drainage hole 3a extending downward and having an opening on the back side of the collar 2 is integrally formed at the lower end of the hollow portion 3. A ventilation hole 5 that communicates in the vertical direction along the external side wall of the hollow bottom portion 4
The lower end of the ventilation hole 5 is provided with an opening 5a that opens downward, and the upper end of the ventilation hole 5 is provided with an opening 5 that is formed by cutting out a part of the side wall of the hollow bottom 4.
It leads to the inside through b. A protrusion 6 protruding outward is formed below the hollow bottom 4, and the protrusion 6 is provided with an insertion hole 6a through which a lead wire is inserted.

7 is a lamp equipped with a lens 8, a housing 9, and a light bulb 10. A cylindrical socket receiver 11 is fixed to the outside of the bottom of the housing 9, and the cylindrical socket part 12 is inserted into the socket receiver 11 with the light bulb 10 interposed therein and is locked and fixed. ing. The waterproof cover 1 is attached so as to cover the socket part 12 and the socket receiver 11, and its collar part 2 is in close contact with the back surface of the housing 9, and the stepped part 2b is set to be in close contact with the outer periphery of the socket receiver 11. A lead wire 13 connected to the socket portion 12 is led out through the insertion hole 6a.

Therefore, in the waterproof cover configured as described above, ventilation is performed through the long ventilation hole 5 that runs vertically along the side wall of the hollow bottom 4, and water droplets that have condensed inside are removed from the bottom. It is easily drained from the drain hole 3a. Furthermore, rainwater that enters from the contact area between the collar portion 2 and the housing 9 is prevented from entering the socket portion 12 by the contact portion between the step portion 2b and the socket receiver 11, and
It is discharged via a.

[Effect of idea]

As described above, the waterproof cover of the present invention has a configuration in which a ventilation hole is formed on the outside of the square tubular hollow bottom part and integrally with the side wall of the bottom part, which communicates in a straight line in the vertical direction. It is possible to form a ventilation hole of sufficient length necessary to prevent
Since it is a linear ventilation hole along the side wall of the hollow bottom, it can be easily molded with a simple mold. In addition, a drainage hole is provided in the hollow part of the waterproof cover, and the stepped part prevents rainwater from entering the inside through the brim, resulting in excellent waterproofing and drainage effects.
