CN2333588Y - Protector for vehicle light switch - Google Patents

Abstract

The utility model discloses a protector for a vehicle light switch, which is welded with a relay, a capacitor, a diode, a socket, and a plug on a printed circuit board which is arranged in a casing of the protector for a vehicle light switch. The socket and the plug pass through holes on both sides of the casing and are connected with original lines and switches of the vehicle. The protector for a vehicle light switch can not only be suitable for the original lines without modifying, but also can effectively protect the switches of the light from being damaged under impact of the high current.

Description

New automobile headlamp switch protector

The utility model relates to a kind of headlamp switch protector of automotive light switch.

At present, the headlamp switch that uses on most of automobiles is everlasting and is worked under the big electric current, and as easy as rolling off a log damage also has light relay is installed on indivedual automobiles, to reduce the intensity of current through headlamp switch.But,, reduced the circuit performance and the inconvenience that brings maintenance of whole car owing to various contact point and line.

Task of the present utility model will overcome above-mentioned shortcoming exactly, provides a kind of and automotive light switch and the matched headlamp switch protector of circuit, thereby improves the reliability of whole car bulb work.

Task of the present utility model is finished like this: on the circuit card in the housing of protector, a relay is installed, two diodes, three electric capacity.Plug and socket and former automobile line are made in the housing both sides, switch is matched, when work, electric current big a road through socket, that circuit card to relay contact is converted to bulb is luminous; Another road electric current through headlamp switch to relay coil, diode, again by the bulb bonding.Find out that thus the electric current of flowing through lamps photoswitch is very little, thereby protected headlamp switch effectively.If strange phenomena appears in protector, only need to dial protector down, take back original socket, and do not influence the service condition of original car bulb.

Describe below in conjunction with embodiment and accompanying drawing.

Fig. 1 is an electrical schematic diagram of the present utility model; Fig. 2 is the outward appearance front section view; Fig. 3 is a left view; Fig. 4 is a right elevation.

As shown in Figure 2, in the housing (1) of protector, printed circuit board (PCB) (2) is installed, is welded with relay (3) on this circuit card, electric capacity (4), diode (5), socket (6) and plug (7).Wherein, relay (3) plays the current conversion effect, and electric capacity (4) and diode (5) are guaranteed relay (3) normal operation, increases the service life of protector.When installing and using; shown in Fig. 3,4; dial the socket (6) of former lighting switch and circuit bonded assembly plug, socket and this protector down and plug (7) is matched and modification that need not do on any circuit gets final product normal operation, can protect headlamp switch can recover original mode of operation easily again so effectively.

Claims (1)

1. A kind of automotive light switch protector; in its housing (1), be mounted with printed circuit board (PCB) (2); be welded with relay (3) on the circuit card; electric capacity (4); diode (5) socket (6) and plug (7); it is characterized in that the hole (9) that the contact pin (8) of socket (6) and plug (7) passes housing (1) both sides reveals.
