Description

Anti-theft igniting switch for motor vehicle

The utility model relates to a kind of automobile-use, particularly motor bike anti-theft igniting switch.

Present motorcycle ignition switch is the keyhole type rotor switch, and it is through after being repeatedly used, and the locking plate in the switch is easy to be opened by non-original key or its succedaneum through permanent abrasion.And general motor bike user can not remove to pay close attention to own motor bike after stopping, and whether the someone removes sled lane ignition lock.Like this, other people particularly steal motorcyclist, just very likely remove to open the motorcycle ignition switch with non-original key or its substitute, and motor bike is just very likely stolen.In addition, some motor bike only need be cut off the connection lead that ignition lock exposes now, just can start motor bike, and like this, motor bike is also just very likely stolen.And warning device is not set all in the present motorcycle ignition switch.

The purpose of this utility model is to provide a kind of self-propelled vehicle ignition lock of being opened by non-original key or its substitute of being difficult for, and it can prevent effectively that self-propelled vehicle, particularly motor bike are stolen.

The utility model is achieved in that a kind of anti-theft igniting switch for motor vehicle, comprise Switch main body and plug-in type switch key, the Switch main body side has a key, Switch main body has some holes that communicate with key up and down, the steel ball that the useful metal elastic element heads in the hole, steel ball exposes key one segment distance, and the lead that is communicated with steel ball by elastic element is arranged outside the hole, lead respectively with firing circuit in corresponding line link to each other; Switch is provided with some contacts on the key, wherein has four contacts to communicate in twos, and when inserting with Switch main body in four steel balls match, thereby reach the energising purpose of lighting a fire.

After the utility model changes present plug-in type contact switch into by original keyhole type rotor switch, if other people, stealer particularly, when going to the sled lane or opening ignition lock with non-original key or its substitute, can not the energized line, thus switch can not be opened, and when the power lead of ignition lock is connected with alarming line, the annunciator that is connected with ignition lock will send chimes of doom, thereby reaches antitheft effect.If stealer removes to cut off the connection lead of ignition lock again, increase by one for again beyond doubt former circuit and open circuit, just more impossible with the motor bike starting and even steal, increased antitheft barrier again one so just for motor bike.

Fig. 1 is an overall structure scheme drawing of the present utility model.

Fig. 2 is schematic circuit diagram of the present utility model.

Below in conjunction with accompanying drawing the utility model being done one describes in detail:

Shown in Fig. 1-2, the utility model is made up of Switch main body 1 and plug-in type switch key 8 two parts.Have key 6 in the middle of Switch main body 1 side, Switch main body 1 has some holes 4 that communicate with groove 6 up and down, the steel ball 5 that useful spring 3 heads in each hole, steel ball 5 exposes groove about 6 1/3, a lead 2 that is connected with steel ball 5 by spring 3 is arranged outside each hole, and lead 2 links to each other with A, B, C, D, the E line that Fig. 2 reports to the police in the ignition lock respectively.Switch key 8 is the plug-in type contact board, many metallic contacts 7 are arranged on the plug-in type contact board 8, wherein there are any four contacts to communicate in twos, match with any four steel balls 5 that expose plane 1/3 in Switch main body 1 groove 6, these four points connect the lead that and are divided into two groups of energy that link to each other with A, C line D, E line among Fig. 2 respectively.Among Fig. 2 among remaining B line and Fig. 1 on the Switch main body 1 above-mentioned 4 the outer leads that all the other each points connected of deduction link to each other.B line among Fig. 2 communicates with E line among Fig. 2 when promptly switch main body 1 inserts non-original key or its substitute under improper situation, makes annunciator 9 generation chimes of dooms, reaches the warning purpose.If any line during the B among Fig. 2, D, E are three-way is connected in A, C line, just can make the ignition circuit short circuit, motor bike can't be started, reach antitheft purpose.

Claims (2)

1, a kind of anti-theft igniting switch for motor vehicle, it is characterized in that it comprises Switch main body (1) and plug-in type switch key (8), Switch main body (1) side has a key (6), Switch main body has some holes (4) that communicate with key (6) up and down, the steel ball that the useful metal elastic element heads in the hole (5), steel ball (5) exposes key (6) one segment distances, the lead (2) that is communicated with steel ball (5) by elastic element (3) is arranged outside the hole, lead (2) respectively with firing circuit in corresponding line (A, C, D, E) link to each other; Switch key (8) is provided with some contacts (8), wherein has any four contacts to communicate in twos, and matches with interior four steel balls of Switch main body when inserting.
