Abstract
The utility model relates to a magnetic safety power supply switch for controlling the power supply of vehicles, which is composed of a controlling contact, an electromagnetic coil, an electromagnet, an electromagnetic sliding block, a push rod, a movable contact, a fixed contact, etc. The high current is controlled by the low current to control the switch-on or the switch-off of the power supply and loads by controlling the on-off of a power supply switch connected in series with the utility model. The utility model has the advantage that accidents of the fire of vehicles and the shock injury of persons are prevented. The utility model has the advantages of simple structure, high reliability, low cost and convenient refit, and is widely suitable for various vehicles.
Description
The utility model relates to a kind of magnetic force insurance mains switch, is specially adapted to the power supply control of various vehicles.
At present, to divide all be to adopt the disconnecting link form to realize controlling the connecting and disconnecting of power supply and load (power consumption equipment) to homemade various vehicles and the imported car power control part that increases repacking.When vehicle launch, closed disconnecting link energized; During vehicle lay-off, draw back disconnecting link and cut off the electricity supply, with the power consumption equipment of protection vehicle., the vehicle drive personnel often do not want to take the trouble or do not note, do not remove to draw back disconnecting link when vehicle lay-off, and disconnecting link is in the close position, and have lost the due control action of disconnecting link, and form the hidden danger of vehicle electric element equipment fire.Simultaneously, what most of vehicle used is alternating current generator, it has a lead often to connect the positive pole of storage battery, from the storage battery to the starter motor, also there is a total lead (electrode line) joint exposing, especially when cleaning or repairing vehicle, the electric discharge phenomena of will striking sparks cause the vehicle fire accident often to take place, the personnel that cause wound with vehicle electric element equipment and burn out, and are very dangerous.
The purpose of this utility model is to overcome above-mentioned weak point of the prior art, and a kind of magnetic force insurance mains switch that can guarantee vehicle power supply control safety is provided.
In order to realize the purpose of this utility model, employing magnetic force insures mains switch and makes it to be connected in series with vehicle ignition switch on vehicle, reaches the connecting and disconnecting of control power supply and load with the big electric current of little Current Control by ignition switch.During vehicle launch, open ignition switch, magnetic force insurance mains switch moves simultaneously, connects the vehicle loop; During vehicle lay-off, disconnect ignition switch, magnetic force insurance mains switch disconnects simultaneously, cuts off the vehicle loop.
The utility model is achieved like this, during vehicle launch, open ignition switch 14, battery positive voltage is connected the control contact 1 of magnetic force insurance mains switch by lead, the energising that links to each other of control contact 1 and solenoid 2 leads, solenoid produces induced field, electromagnet 4 is magnetized with electromagnetism slide block 5, produce suction, electromagnetism slide block 5 is attracted to the electromagnet 4 that is fixed on the shell 8 on can not the pad 15 of shift position along solenoid frame 3, penetrator ram 6 also overcomes the spring force of return spring 12, makes the armature contact 10 that is fixed on the push rod 6 contact the energized loop with fixed contact 11 on being fixed on shell front end housing 13.One end of top spring 9 is fixed on the locking plate 7, and its effect is to make more firm that armature contact 10 contacts with fixed contact 11.
When vehicle lay-off, disconnect ignition switch 14, cut off the electric current in the lead, control contact 1, solenoid 2 do not have electric current, do not produce induced field, and electromagnet 4 and electromagnetism slide block 5 do not produce suction, return spring 12 overcomes the spring force of top spring 9, penetrator ram 6 and armature contact 10 and electromagnetism slide block 5 fixed thereon are got back to the home position, and magnetic force insurance mains switch disconnects, and cuts off the loop of vehicle power consumption equipment.
Fig. 1 is the structure chart of magnetic force insurance mains switch.
Fig. 2 is the position view that magnetic force insurance mains switch is serially connected in vehicle power supply.
1-controls the contact, 2-solenoid, 3-solenoid frame, 4-electromagnet, 5-electromagnetism slide block, the 6-push rod, 7-locks pad, 8-shell, 9-top spring, 10-armature contact, the 11-fixed contact, 12-return spring, 13-shell front end housing, 14-ignition switch, 15-pad.
Frame of broken lines is a magnetic force insurance mains switch among Fig. 2
The structure of the magnetic force insurance mains switch shown in accompanying drawing 1 and the accompanying drawing 2 and tandem link are the most preferred embodiment of liberation CA-10 truck.Magnetic force is insured on the negative pole that mains switch is serially connected in vehicle battery.During vehicle launch, open ignition switch, the vehicle loop is connected in the energising of magnetic force insurance mains switch; During vehicle lay-off, disconnect ignition switch, the vehicle loop is cut off in the outage of magnetic force insurance mains switch.
The utility model has the advantages that the vehicle drive personnel only need opening or closing by the control ignition switch, namely can control big electric current by little electric current, reach being switched on or switched off of control vehicle power supply and load, greatly reduce or avoided the vehicle drive personnel usually behind vehicle lay-off, constantly operate on lock and the vehicle electric element fire and the personnel that produce wound accident. The utility model compact conformation, simple, dependable performance, cost is low, and repacking is convenient, and through practicality, effect is remarkable. Be widely used in various vehicles.
