Abstract
A horn switch protector structurally consists of a 12V40A relay, a circuit A, a circuit B, a circuit C and a circuit D, and is characterized in that an E point of the 12V40A relay is connected with the circuit A, an F point of the 12V40A relay is connected with the circuit B, a D point of the 12V40A relay is connected with the circuit D, and a G point of the 12V40A relay is connected with the circuit C. The horn switch protector can solve the problem of contact sintering and poor contact of the horn switch.
Description
Technical field
The utility model relates to a kind of on-off system of automobile, is a kind of horn switch protector concretely.
Background technology
At present, the most of contact that adopts of the horn switch of automobile is connected, and this structure construction is simple, but there is obvious weak point: because the loudspeaker electric current is big, easily produce electro spark when horn switch is connected, cause contact sintering, bad contact, influenced the normal operation of loudspeaker.
The utility model content
The purpose of this utility model is to provide a kind of horn switch protector, makes guaranteeing on the simply constructed basis of former on-off system also have the big electric current of the horn switch of elimination.
The utility model is realized with following technical scheme: this horn switch protector mainly is made up of 12V40 relay, circuit A, circuit B, circuit C, circuit D.It is characterized in that the E point of 12V40A relay is connected with circuit A, the F point of 12V40A relay is connected with circuit B, and the D point of 12V40A relay is connected with circuit D, and the G point of 12V40A relay is connected with circuit C.Two lines that at first former car connect loudspeaker are pulled up and are connected with circuit B with the circuit A of horn switch protector; positive pole that connects storage battery of two white wires of horn switch protector; another root connects loudspeaker; the another one plug grounding jumper of loudspeaker; in the time of the blast the horn switch; at this moment; electric current is the coil that arrives the 12V40A relay; coil produces magnetic; normal combination battle; electric current directly is introduced to loudspeaker from the positive pole of storage battery, and loudspeaker pipe, and realizes the function of the big electric current of the little current control of horn switch.
Beneficial effect is: described horn switch protector has the function that solves horn switch contact sintering, bad contact.
