Abstract
The utility model relates to an automobile ignition switch including an ignition lock cylinder assembly, a shell assembly and a conductive plate assembly. The conductive plate assembly includes a movable contact spring base, a contact panel spring, a large contact panel, a small contact panel and a pin assembly. The pin assembly includes a plurality of binding posts and at least two annular slides. The large contact panel is sleeved on an outer shell of the movable contact spring base, and the large contact panel and the outer shell of the movable contact spring base are in an interference fit. An opening is arranged in the middle of the small contact panel. The small contact panel connects with an end of the movable contact spring base in an inserting manner, and the small contact panel and the movable contact spring base are in an interference fit. At least three convex arc-shape surfaces are arranged in a plane of the large contact panel and the small contact panel close to the annular slides. The contact arc-shaped surfaces contact with the annular slides in a sliding manner. By using the automobile ignition switch in the utility model, the contact working currents are reduced. Thus, the integrated heat energy is resolved. And the reliability and the service lifetime of the automobile ignition switch are improved.

Summary of the invention
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of automobile ignition switch of a kind of operating current of shunting the contact, dependable performance, long service life.
For realizing above-mentioned purpose; The utility model provides following technical scheme: a kind of automobile ignition switch; Comprise ignition lock core assembly, casing assembly and conductive plate assembly, it is characterized in that: described conductive plate assembly comprises movable contact bar, touch panel spring, big touch panel, little touch panel and pin assembly, and described pin assembly comprises some binding posts and at least two annular slide tracks; Described movable contact bar one end is provided with some looping pits; In said some looping pits the touch panel spring is housed respectively, said touch panel spring one end stretches out and compresses big touch panel or little touch panel, and described big touch panel is socketed on the shell body of movable contact bar and interference fit; Be provided with breach in the middle of the described little touch panel; Described little touch panel and described movable contact bar one end are pegged graft and interference fit, and described big touch panel and little touch panel are provided with at least three protruding arcuate surfaces near the plane of annular slide track, and described protruding arcuate surface is connected with described annular slide track sliding contact.
Through adopting technique scheme, adopt the way of contact of protruding arcuate surface, can effectively reduce contact temperature, avoid contact meeting erosion and wear.
The utility model further is set to: the shape of described big touch panel and little touch panel is annular, and described big touch panel all has an arcuate surface to be connected with corresponding annular slide track sliding contact simultaneously with little touch panel.
Through adopting technique scheme, adopt touch panel to be shaped as annular, can effectively the operating current on the arcuate surface be diverted on the touch panel face.
The utility model further is set to: described binding post is processed to form with the equal corresponding formula that is integral of described annular slide track, and silver-plated processing is all adopted on the surface of described binding post.
Through adopting technique scheme, make the utility model automobile ignition switch conductive effect better.
A kind of automobile ignition switch beneficial technical effects of the utility model is: owing to adopted the arcuate surface way of contact; Original very large electric current is reduced the operating current of contact through design; Concentrated heat is decomposed, improve the functional reliability of product, prolong the useful life of switch.
Below in conjunction with accompanying drawing the utility model is further described.
