Abstract

The invention discloses a pure pneumatic type contactor. The contactor comprises a pneumatic structure, a mechanical holding structure, an insulator group and a contact part, wherein the pneumatic structure comprises an air cylinder cover, an air cylinder, an air generator, a pressing block, a first rubber pad, a second rubber pad, a baffle, a piston, a bearing and a reset spring, the insulator group comprises an insulator, an inner sleeve and an overtravel spring, the mechanical holding structure comprises a fixing ring, a hidden pin, a thrust spring, a locking bolt, a pushing block, a limiting block, a connecting rod and an opening spring, and a contact part comprises a moving contact, a static contact, an airtight insulating shell and a corrugated pipe. The contactor is advantaged in that the contactor is different from a traditional contactor based on the electromagnetic principle, the pure pneumatic type contactor completely replaces an electromagnetic mechanism, closing is achieved in a pneumatic mode, and traditional combination of electricity, magnetism and machinery is replaced with combination of electricity, gas and machinery, and the pure pneumatic contactor provided bythe invention can be applied to magnetic interference occasions.

Description

technical field [0001] The invention belongs to the field of contactor design and relates to a contactor which directly adopts pneumatic closing without an electromagnetic mechanism. Background technique [0002] Traditional contactors switch and maintain the closing and opening states through electromagnetic principles, and are prone to failure in the event of magnetic interference. Therefore, a contactor that can be applied in the field of magnetic interference and can realize mechanical retention has emerged as the times require. Contents of the invention [0003] The purpose of the present invention is to provide a purely pneumatic contactor, the contactor realizes closing through the pneumatic structure, and the mechanical holding structure realizes opening and closing maintenance. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A purely pneumatic contactor, its body structure includes a pneumatic structu...
