Background

Relays are generally composed of an electromagnet, an armature, a spring plate, a contact, and the like. As long as a certain voltage is applied to the two ends of the coil, a certain current flows in the coil, so that an electromagnetic effect is generated, the armature iron overcomes the pulling force of the return spring and is attracted to the iron core under the attraction effect of the electromagnetic force, and the movable contact of the armature iron is driven to be attracted with the fixed contact (normally open contact). When the coil is powered off, the electromagnetic attraction force disappears, and the armature returns to the original position under the counterforce of the spring, so that the movable contact and the original static contact (normally closed contact) are attracted. Thus, the circuit is attracted and released, thereby achieving the purposes of conduction and cut-off in the circuit.

At present, the relay that the car was used includes electromagnetic component and base subassembly usually, in order to guarantee automobile electrical equipment's normal use, there is more strict requirement to the relay, the volume that had required the relay can not be too big, but the overcurrent load ability of relay is required simultaneously, but the reduction of volume, it is little to mean the space in the relay, creepage distance and spatial distance are not enough, cause the uncontrollable high surge voltage electric current of product, the easy too early damage of relay product under the condition of high-pressure high current, there is the condition that product life is low.
