Problems solved by technology
[0003] At present, the contactors on the market do not have self-protection function, which cannot meet people's needs. We know that thermal relay is an electronic component. The bimetal sheet of the coefficient is deformed. When the deformation reaches a certain distance, the connecting rod will be pushed to disconnect the control circuit, so that the contactor will be de-energized, the main circuit will be disconnected, and the overload protection of the circuit will be realized. Therefore, we provide A contactor with a self-protection function is installed on the contactor to prevent overheating, so as to solve the problems existing in the existing contactor

The present invention discloses a contactor having a self protection function. The contactor comprises a contactor main body and a pedestal fixedly installed at the bottom portion of the contactor main body. One side of the contactor main body is provided with a thermal relay, and the thermal relay is in contact with the contactor main body; a slide block is fixedly installed at the bottom portionof the thermal relay; a slide rail is fixedly installed at the top portion of the pedestal, and the thermal relay is slidingly installed on the slide rail through the slide block; a placing camber arranged on the pedestal is arranged below the slide rail; and a baffle is movably installed in the placing chamber, and a stop block is fixedly installed at the bottom end of the baffle. The contactorhaving self protection function is provided with the thermal relay, the thermal relay can control on and off of a circuit when heat generated in the working of the contactor is too large, so that thecontactor is powered out to achieve overload protection of the contactor, and therefore, the usage life of the contactor is effectively improved, the thermal relay is convenient for people to install,the assembling efficiency is improved, and people's usage demands are satisfied.
Description
technical field [0001] The invention relates to the technical field of electronic products, in particular to a contactor with self-protection function. 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 contact is closed to control the load of electrical appliances. In electrical engineering, it is often used as a control object for motors because it can quickly cut off the AC and DC main circuits and can frequently connect to high-current control circuits. It can be used to control power loads such as factory equipment, electric heaters, working machines and various electric power units. The contactor can not only connect and cut off the circuit, but also has the function of low-voltage release protection....
