Waterproof direct current contactor

Abstract

The invention discloses a waterproof direct current contactor which comprises a direct current contactor body. Fixed contacts and a movable contact are arranged in the direct current contactor body; the outer ends of two fixed contacts are exposed on the upper lateral surface of the direct current contactor body; two coil outgoing lines and a pair of pressure line terminals are arranged on the upper lateral surface of the direct current contactor body; the pair of pressure line terminals are respectively fixed to the outer ends of two fixed contacts and respectively lead out one main loop outgoing line; the waterproof direct current contactor is additionally provided with a plastic sleeve; the lower end of the plastic sleeve fixedly sleeves the peripheral surface of the upper end of the contactor body, and a height of the upper end face of the plastic sleeve is greater than that of each pressure line terminal; a waterproof insulation material is packaged in the plastic sleeve so as topackage the pressure line terminals in the plastic sleeve; the outer ends of two main loop outgoing lines and two coil outgoing lines are respectively led out of the waterproof insulation material. The waterproof direct current contactor meets the waterproof demand of a product in a case that the waterproof demand space is limited, and has the advantages of simple structure, low cost, good waterproofness and the like.

Description

technical field [0001] The invention relates to a DC contactor, in particular to a waterproof DC contactor. Background technique [0002] The main contacts of existing DC contactor products are exposed in the air, which has certain limitations for some occasions that require waterproofing. In order to overcome this problem, waterproof high-voltage distribution boxes are commonly used in the market to isolate the contactor from the outside world, but this method is expensive and takes up space. Contents of the invention [0003] In order to overcome the above defects, the present invention provides a waterproof DC contactor, which not only has a simple structure and low cost, but also has excellent waterproof performance. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a waterproof DC contactor, including a DC contactor body, a static contact and a moving contact are arranged in the DC contactor body, and the two...
