Description

Waterproof gram head

Technical Field

The utility model relates to the technical field of connectors, in particular to a waterproof gram head.

Background

With the development of new energy and ship mechanical equipment, two types of fastening and sealing of cables are available in the market, wherein one type of the cable fastening and sealing is formed by a plastic shell and a sealing ring, and the other type of the cable fastening and sealing is formed by a metal piece, a nylon core sleeve and a rubber sealing piece.

The first is a plastic part, so that the cable can not meet the design requirement when being grounded in the electromagnetic shielding environment, and the second is a metal structure, and the electromagnetic shielding grounding effect can be achieved, but the waterproof sealing effect is achieved by pressing the tight sealing ring through the claw-shaped nylon core sleeve during assembly, and the torsion of the nylon core sleeve can not reach the waterproof sealing effect when the cable is used.
