Description

Automobile ignition switch

Technical field

The utility model relates to a kind of automobile ignition switch.

Background technology

Automobile ignition switch commonly used adopts rotary-disk type structure, and its key inserts lock core and drives dial rotation, by touching of active and static contact, makes electrical equipment conducting on automotive ignition and other car.Because rotating disk is made of plastics mostly, intensity and durability often do not reach the requirement of high-power motor vehicle.Common automobile ignition switch mostly is seven contacts most, and its maximum power is less than 25 amperes.Be subjected to the restriction of turntable structure, power is difficult to improve, and can not satisfy military car or oversize vehicle multiconductor, powerful requirement.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of multiconductor, powerful automobile ignition switch.

For solving the problems of the technologies described above, a kind of automobile ignition switch of the present utility model, comprise pedestal, be fixed in igniting tapered end and transducer on the pedestal, its improvement is: it also comprises igniting shank of the key, the transverse moving mechanism that is connected with pedestal, described transverse moving mechanism by the gear that is connected tooth bar in the pedestal, be meshed with tooth bar, with gear mutually the compressing tablet of crimping form with gland, the theft-proof bolt that is connected with tooth bar and alignment pin.

As a kind of improvement of the present utility model, end, key that described igniting shank of the key is arranged in the igniting tapered end insert lock core through the igniting shank of the key; Described transducer comprises the pedestal that is fixed in the pedestal side, is installed in the insulation slide block in the pedestal, the movable contact spring that is connected with the insulation slide block, and the stationary contact bar of pedestal Joint and be fixed in static contact on the stationary contact bar, and described static contact is electrically connected with the car electrics binding post.

As another kind of improvement the of the present utility model, described rack drives theft-proof bolt, alignment pin move laterally, and alignment pin promotes movable contact spring and moves laterally, and described movable contact spring and static contact are tight fit.

The utility model has replaced traditional rotary-disk type structure with a transverse moving mechanism, and the transducer that adopts gear-tooth bar engaged transmission and be complementary with it makes the dynamic and static contact of seven couples of common ignition switch increase to ten a pair of dynamic and static contacts; The rotation of dynamic and static contact touched to be modified into to move touch, efficiently solve the technical problem that the rotating disc type ignition switch is subjected to structural limitations power to be difficult to increase, power is brought up to more than the 50A by the 25A of traditional ignition switch, has fully satisfied the demand of military vehicle or other oversize vehicle.Replace existing plastics rotating disk with gear-rackwork, also improved the intensity and the useful life of ignition switch.Set up an igniting shank of the key on the igniting tapered end, the corresponding increase of driving torque guarantees that key is indeformable, has improved reliability.

Embodiment

By in the automobile ignition switch structural representation shown in Fig. 1 as can be seen, a kind of automobile ignition switch, comprise pedestal 1, be fixed in igniting tapered end 2 and transducer 3 on the pedestal 1, it also comprises igniting shank of the key 203, the transverse moving mechanism 4 that is connected with pedestal 1, described transverse moving mechanism 4 by the gear 402 that is fixed in tooth bar 405 in the pedestal 1, be meshed with tooth bar 405, with gear 402 mutually the compressing tablet 403 of crimping form with gland 404, the theft-proof bolt 407 that is connected with tooth bar 405 and alignment pin 406.

Fig. 2～3 show the structural representation of automobile ignition switch pedestal, igniting tapered end.End, key 202 that described igniting shank of the key 203 is arranged in igniting tapered end 2 insert lock core 201 through igniting shank of the key 203; Described tooth bar 403 drives theft-proof bolt 405, alignment pin 407 moves laterally, and alignment pin 407 promotes movable contact spring 302 and moves laterally, and described movable contact spring 303 is a tight fit with static contact 304.

Referring to the converter structure figure shown in Fig. 4, described transducer 3 comprises the pedestal 301 that is fixed in pedestal 1 one sides, is installed in the insulation slide block 302 in the pedestal 301, the movable contact spring 303 that is connected with insulation slide block 302, and the stationary contact bar 305 of pedestal 301 Joints and be fixed in static contact 304 on the stationary contact bar 305, and described static contact 304 is electrically connected with the car electrics binding post.
