Dual-frame single-phase contactor

Abstract

The invention discloses a dual-frame single-phase contactor. The dual-frame single-phase contactor comprises a main loop, an electromagnetic mechanism, a rotation support point, an operation mechanismand an installation frame, wherein the installation frame comprises an inner frame and an outer frame, the inner frame is of a square frame, an opening is formed in a side surface of the square frame, the main loop and the electromagnetic mechanism are fixed in the inner frame, the rotation support point and the operation mechanism are fixed at an end surface of the inner frame to form a contactor main body, the outer frame comprises a lower frame and a cover plate, an upper end of the lower frame is opened, the cover plate is covered on the lower frame, clamping grooves are formed in positions, corresponding to two wiring ends, of a side surface of the lower frame, the contactor main body is arranged in the lower frame and is fixed by a positioning pin, and the cover plate is covered onthe lower frame and is fixed by a fixed screw. The dual-frame single-phase contactor employs a structure of the inner frame and the outer frame, the inner frame is used for ensuring performance parameter characteristic of a product, the outer frame is used for fixing of various installation modes, and the performance consistency of the product is ensured.

Description

technical field [0001] The invention relates to a contactor, in particular to a double-frame single-phase contactor. Background technique [0002] The existing single-phase vacuum contactor adopts a single-frame structure, which cannot meet the special performance parameter requirements of customers. It is also necessary to repeatedly debug the product performance parameters for the regular needs of customers, and when the parameters need to be adjusted during the production and debugging process It is necessary to dismantle all the contactors as a whole, and reassemble after the adjustment is completed. In some cases, a single contactor needs to be disassembled and assembled multiple times, which affects the production efficiency and leads to poor product consistency. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a double-frame single-phase contactor. The product can be debugged without assembling the product dur...
