Problems solved by technology

[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 traditional contactor contacts 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.

Abstract

The invention discloses a low-voltage contactor. The low-voltage contactor comprises an upright post, a hydraulic cylinder, a worm and a circular base plate, and is characterized in that a sleeve is mounted at the central position of the circular base plate; three brackets, three sets of first axis pins, three sets of second axis pins and three contact elements are further mounted above the circular base plate; each set of first axis pins comprises two first axis pins; each set of second axis pins comprises two second axis pins; the two second axis pins are symmetrically mounted on the outer side of the two first axis pins; and the circular base plate is made from an insulating material. The opening and closing of the contactor are controlled by the hydraulic cylinder, the worm and a gear, and the low-voltage contactor has the characteristics of great contactor contact pressure, reliable contact and high response speed.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a 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 contactor, which controls the opening and closing of the contactor through a hydraulic cylinder and a worm gear, and has the characteristics of large contact pressure, reliable contact, and fast response speed. [0004] The technical solution used in the present invention is: a low-voltage con...
