Abstract

The invention discloses a low voltage contactor with a good protection line effect. The contactor comprises a shell. A center point of a back side of an inner wall of a shell is fixedly connected to aslide rail. A surface of the slide rail is slidingly connected to a slide block. A top and a bottom of the slide block are symmetrically provided with two elastic belts. One side of each elastic belt, which is far away from the slide block, is fixedly connected to the inner wall of the shell. In the invention, through arranging the slide rail, the slide block, the elastic belts, a first limitingplate, a moving plate, a second limiting plate, a limiting telescopic rod, an electric wire fixing plate, a fixing bolt, a moving block, a slide rod, a fixing vertical plate, a transverse spring, a connection plate, limiting block and a smooth pad, the protection line effect of the low voltage contactor is good, an electric wire is prevented from being disconnected to the contactor due to inadvertent pulling, an accident is avoided, unnecessary economic losses are prevented, people lives are not threatened and great convenience is brought for a user.

Description

technical field

[0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a low-voltage contactor with good protection effect on circuits. Background technique

[0002] Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in electric power, power distribution and power consumption. In a broad sense, contactors refer to the use of coils to flow currents in industrial electricity to generate magnetic fields. The contacts are closed to control the load of electrical appliances. The contactors are divided into DC contactors and shunt contactors according to the form of the main contact connection circuit. According to the operating mechanism, they are divided into electromagnetic contactors and permanent magnet contactors. During the contactor process, the common low-voltage contactor protection circuit is not ideal, and the wire will be disconnected from the contactor due to inadve...
