Description

Electromagnetically driven switching electrical appliances with decomposable and replaceable structure

Technical field:

The utility model relates to an electromagnetically driven switching device with decomposable and replaceable structure.

Background technique:

Electromagnetic switch is a circuit switch control device. Usually used in automatic control circuits, it is actually an "automatic switch" that uses a small current to control the operation of a large current. It plays the role of automatic adjustment, safety protection, conversion circuit and so on in the circuit. It is generally composed of iron core, coil, armature, contact reed, etc. As long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect, and the armature will be attracted by the electromagnetic force. Under the action, it overcomes the pulling force of the return spring and attracts to the iron core, thereby driving the moving contact of the armature and the static contact (normally open contact) to attract. When the coil is powered off, the electromagnetic attraction will also disappear, and the armature will return to its original position under the reaction force of the spring, so that the moving contact and the original static contact (normally closed contact) will be released. In this way, the attraction and release achieve the purpose of conducting and cutting off in the circuit. In the prior art, these three systems are generally integrated and designed. Its advantages are high integration and easy processing. The disadvantage is that if a system component is damaged, the entire electrical appliance including undamaged parts needs to be replaced as a whole, which is wasteful. It is well known that the life of the mechanical system of electromagnetic switching appliances far exceeds the electrical life, even reaching an order of magnitude or more.
