Description
Technical Field
The invention belongs to the technical field of electrical elements, and particularly relates to a small high-power relay with internal enhanced heat dissipation.
Background
The relay is an electric control device, is usually applied to an automatic control circuit, is an 'automatic switch' which uses a small current to control a large current to operate, and plays the roles of automatic regulation, safety protection, circuit conversion and the like in the circuit. When the relay works, as long as a certain voltage is added at the two ends of the coil, a certain current can flow in the coil, so that an electromagnetic effect is generated, and then the movable spring is pushed by the push rod until the movable spring is attracted with the static spring. When the coil is powered off and the electromagnetic attraction is small, the armature returns to the original position, the movable spring is separated from the static spring, and a large amount of heat can be generated during the working of the relay, so that a heat dissipation structure is arranged in the relay.
