A low-voltage contactor for electrical use

Abstract

The invention discloses an electrical low-voltage contactor. The electrical low-voltage contactor comprises a bottom plate, a push air cylinder, a sliding frame and two contact systems, wherein the push air cylinder is vertically arranged on the bottom plate, the sliding frame is arranged at an end part of a piston rod of the push air cylinder, sliding windows are symmetrically arranged at two sides of the sliding frame, sliding blocks of the two contact systems are respectively arranged in the two sliding windows in the sliding frame in a sliding way, sliding strips are arranged under the sliding blocks, a roller is rotatably arranged at one side of each sliding strip, a rotation rod is hinged with the other end of the sliding strip, the other end of the rotation rod is arranged on the bottom plate in a hinged way, the middle part of the hinged rod is arranged on the bottom plate in a hinged way, a lower roller is rotatably arranged at a lower end of the hinged rod, a horizontal push rod is arranged in a through hole of a fixed block in a sliding way, a horizontal push plate is arranged at one end of the horizontal push rod, a contact is arranged at the other end of the horizontal push rod, and a wiring head is arranged on the horizontal push rod. The opening and the closing of the contactor are controlled by the push air cylinder, and the electrical low-voltage contactor has the characteristics of large contact pressure of the contact, reliable contact and rapid response speed.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to an electrical low-voltage contactor. Background technique [0002] Contactors are electrical appliances used to frequently switch on and off AC and DC main circuits and large-capacity control circuits over a long distance. Groups, etc., the contact pressure between the contacts of the traditional contactor is small, which is prone to poor contact and other phenomena, so there is an urgent need for a contactor with high contact pressure and high contact reliability. Contents of the invention [0003] In view of the above problems, the present invention provides a low-voltage electrical contactor, which controls the opening and closing of the contactor by pushing the cylinder, and has the characteristics of high contact pressure, reliable contact and fast response. [0004] The technical solution used in the present invention is: an electrical low-volta...
