Abstract

The utility model relates to a theft proof ignition coil for vehicles. In the inner part of the traditional ignition coil, a switch is added on a conducting wire between a low-voltage coil and a connecting post for the switch. When the switch is switched on, current can pass through the low-voltage coil and high voltage current can produced. Thus the vehicle can be started. Whereas, when the switch is turned off, the vehicle can not be started, achieving the theft proof purpose of the vehicle. The utility model has the advantages of convenient operation, production and installation, etc.

Description

Automobile ignition coil

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

At present the conventional point fire coil that generally uses of automobile is that 12 volts low-tension current is become 1.5～20,000 volts high-tension current through liters such as low voltage winding, high-tension coil, iron cores, and this spark coil can not possess anti-theft feature, causes automobile to lose easily.

The purpose of this utility model is to provide a kind of automobile ignition coil that can be antitheft, can prevent effectively that automobile from losing.

For achieving the above object, the technical solution adopted in the utility model is: connect with switch at the inner low voltage winding of conventional point fire coil and being connected between the post be provided with a switch on the lead, this switch can make the low voltage winding current loop be in disconnection, conducting two states.When electric current after switch connects post and flows into, at first pass through this switch, when this switch connection, the low voltage winding on iron core has electric current to pass through, and flows to low crimping post, just produces high-tension current through iron core, high-tension coil etc. again, automobile can start; When this switch disconnects, do not have electric current to pass through in the low voltage winding on the contrary, just can not produce high-tension current yet, automobile can not be started.

Owing to be provided with a switch in the low tension loop in the such scheme in spark coil, when disconnecting or connecting this switch, can make automobile can not start maybe can start, reach the purpose of automobile burglar, and simple in structure, easy to use.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1, the utility model circuit theory diagrams,

Fig. 2, the utility model mode of execution structural representation.

In circuit theory diagrams shown in Figure 1, connect with switch at the inner low voltage winding 2 of general point fire coil and being connected between the post 6 to be provided with a switch 5 on the lead, this switch can make the low voltage winding current loop be in disconnection, conducting two states, when electric current after switch connects post 6 and flows into, at first pass through switch 5, when switch 5 is connected, low voltage winding 2 on iron core 7 has electric current to pass through, flow to low crimping post 1, just produce high-tension current through iron core 7, high-tension coil 3 etc. again, automobile can start; When switch 5 disconnects, do not have electric current to pass through in the low voltage winding 2 on the contrary, just can not produce high-tension current yet, automobile can not be started.

Fig. 2 is the structural representation by a kind of automobile ignition coil of above-mentioned principle design.Below general point fire coil inside, add an isolating partition 4 with holes, this isolating partition 4 is fixedlyed connected with iron shell 8, existing automobile ignition switch 5 one ends are fixed on the isolating partition 4, the other end that has keyhole is positioned at the bottom of iron shell 8, and the hole of the wiring of this switch 5 being passed isolating partition 4 is connected in the loop of low voltage winding 2.During use, key 9 is inserted in the switch 5, when turning on positi, electric current connects post 6 from switch and flows to low crimping post 1 through switch 5, low voltage winding 2, produces high-tension current by high-tension coil 3, iron core 7, and automobile can be started; When on the contrary key turns to disconnection being put, do not have electric current to pass through in the low voltage winding 2, also just can not produce high-tension current, automobile also just can not start, and has reached antitheft purpose.
