Description

Bulb socket for automotive lamps.

The present invention relates to a bulb socket for an automobile lamp, and more particularly, to provide a bulb socket having an air vent hole integrally, thereby contributing to cost reduction and process reduction resulting from the formation of an air vent hole.

Automobile lamps are used as a means of securing a safe watch and signals to surrounding vehicles when driving at night, a headlamp for securing a forward clock, and a means of securing a clock in bad weather and a means of recognizing their vehicles to surrounding vehicles. Pogramf;

There are many types, such as tail lamps that integrate the driving direction of the vehicle, the indication of the reverse state, and the stop lamp that checks the braking state, and the vehicle width lamp and the interior lamp.

These lamps are composed of a lamp housing having a reflective surface (reflecting mirror) inside, a lamp lens attached to the front of the lamp housing, a bulb socket coupled to the rear of the lamp housing to couple the bulb (bulb).

In particular, in the case of a large lamp such as a head lamp, the air vent hole is provided as a means for controlling the temperature at which the inside of the lamp becomes high due to the lighting of the bulb and maintaining the air pressure inside the lamp in an appropriate state.

The lamp 1 for motor vehicle of the prior art is as shown in FIG. 1;

A socket 5 having a bulb 4 coupled to the rear of the lamp housing 3 having a lamp lens 2 in front is provided, and below the bulb socket 5, an air vent integrally with the lamp housing 3 is provided. The hole 6 is formed.

The rear side of the air vent hole 6 is bent (zigzag or round type) watertight tube to prevent the penetration of moisture or foreign matter into the lamp housing (3).

In the prior art as described above, the operation of forming an air vent hole in a large lamp housing is quite difficult, as well as an increase in ancillary parts such as a watertight tube connected to the air vent hole, thereby providing a factor of cost increase.

In particular, since watertight tubes protrude from the rear of the lamp housing, when the lamp is mounted, it has a lot of inconveniences, such as checking the interference state between the rear of the lamp housing and other components.

Therefore, the present invention has been made to solve the problems as described above to improve the bulb socket fastened to the bulb coupling in the rear of the lamp housing to have the air vent hole in the bulb socket to eliminate the factor of cost increase The purpose is to improve the wearability.

Explain.

The lamp 10 for a vehicle has a configuration in which a bulb socket 15 having a bulb base 14 for coupling the bulb 13 to the rear of the lamp housing 12 having the lamp lens 11 in the front is mounted. .

In the present invention, the bulb socket 15 may be improved to a structure having an air vent hole, thereby reducing ancillary processes and components, such as forming a separate air vent hole in the lamp housing 12, thereby contributing to mounting and quality stability. Make sure

The configuration of the present invention for achieving the above object;

The inner upper side of the bulb socket 15 that is torsionally coupled with the fastening hole 16 formed at the rear of the lamp housing 12, the inner side so as to maintain the upper side and a predetermined space of the bulb base 14 for coupling the bulb 13 The rib 17 protrudes to form a single body.

A socket fitted to the rear end of the bulb socket 15 to maintain the bulb base 14 coupled with the rib 17 on the outside of the bulb socket 15 of the opposite position where the rib 17 is formed. Maintain a predetermined distance (S) and the lower end of the cover 19 to have a diameter reducing portion 20 to form a passage through which external air can be introduced.

The outer side of the wiring hole 22 formed for inserting the wiring 21 in the center of the rear end of the bulb socket 15 is forcibly coupled to the socket cover 19 to be sealed with a packing 23 for maintaining airtightness. It is configured to further protrude rearward auxiliary ribs 25 for preventing the air flow free.

The present invention as described above;

When the bulb 13 is turned on, the inside of the lamp 10 becomes high in temperature, and the air pressure also has a considerable difference from the outside.

The temperature difference and the air pressure difference are resolved through the air vent hole 30 formed by the rib 17 and the diameter reduction part 20 and the auxiliary rib 25 further formed in the bulb socket 15.

By the rib 17 formed in the bulb socket 15 and the diameter reduction portion 20 formed outside, the bulb base 14 is maintained in a stable state in the bulb socket 15, and the bulb base 14 ) And the space generated between the rib 17 is free to flow to the outside air.

The space generated between the bulb base 14 and the rib 17 is formed by the bulb socket 15 by the auxiliary ribs 25 protruding to the outside of the wiring hole 22 formed at the rear end of the bulb socket 15. The air flow is freed by maintaining a certain space with the packing 23 coupled to the socket cover 19 coupled to the outside of the.

The space between the packing 23 and the auxiliary ribs 25 is generated between the diameter reduction portion 20 and the socket cover 19 formed on the outside of the bulb socket 15 to allow direct flow with the outside. Outside and inside the lamp housing 12 is conductive.

The present invention as described above;

Since there is no protruding part of the rear of the lamp housing 12 and no air vent hole is formed in the lamp housing 12 itself, the air flow inside and outside the lamp housing 12 is free, so that temperature and air pressure can be easily adjusted. Of course, interference with surrounding components is excluded during installation.

The present invention as described above has the effect of eliminating the factor of cost increase and improving the mountability by improving the bulb socket fastened for bulb coupling at the rear of the lamp housing to have the air vent hole in the bulb socket integrally. .
