Anti-falling and anti-damage alternating current contactor

Abstract

The invention discloses an anti-falling and anti-damage alternating current contactor which comprises a bearing box, first clamping grooves are symmetrically formed in the left side and the right sideof the top of the bottom of an inner cavity of the bearing box, second clamping grooves are formed in the bottoms of the first clamping grooves, first grooves are formed in the bottom of the inner cavity of the bearing box, second grooves are formed in the bottoms of the first grooves; screws are inserted into the middle of the second grooves, nuts are fixedly connected to the front ends of the screws, and a first fixing plate is arranged in the middle of an inner cavity of the first clamping grooves. According to the anti-falling and anti-damage alternating current contactor, the second clamping groove is T-shaped in a top view, the second clamping grooves are matched with the first fixing block and the first clamping block, and the first clamping grooves are matched with the first clamping block, so that the first fixing plate can be fixedly suspended in the inner cavity of the bearing box through the first fixing block and the first clamping block; and through arrangement of firstfixing rods, the device body at the top of the bearing plate can be conveniently carried and mounted.

Description

technical field [0001] The invention relates to the field of AC contactors, in particular to an AC contactor that prevents falling off and damage. Background technique [0002] Contactors are divided into AC contactors and DC contactors, which are used in electric power, power distribution and power consumption. , the working principle of the AC contactor is: when the coil of the AC contactor is energized, the coil current will generate a magnetic field, and the generated magnetic field will cause the static iron core to generate electromagnetic force to attract the moving iron core, and drive the AC contactor to move, and the normally closed contact Disconnected, the open contact is closed, and the two are linked. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring to restore the contact. The normally open contact is disconnected and the normally closed contact is closed. At present, t...

[0002] Contactors are divided into AC contactors and DC contactors, which are used in electric power, power distribution and power consumption. , the working principle of the AC contactor is: when the coil of the AC contactor is energized, the coil current will generate a magnetic field, and the generated magnetic field will cause the static iron core to generate electromagnetic force to attract the moving iron core, and drive the AC contactor to move, and the normally closed contact Disconnected, the open contact is closed, and the two are linked. When the coil is powered off, the electromagnetic attraction disappears, and the armature is released under the action of the release spring to restore the contact. The normally open contact is disconnected and the normally closed contact is closed. At present, the AC contactors on the market do not have a protective structure when installed, and cannot isolate the dust in the air. For a long time, the electromagnetic force generated by the static iron core will not be able to attract the moving iron core, resulting in damage. Therefore, a special contactor is required. Anti-dropping and anti-damage AC contactors to solve this problem
