Description

Waterproof sealing ring for electrical connector

This creation relates to the field of a waterproof electrical connector, in particular to a waterproof sealing ring used on an electrical connector.

Current waterproof electrical connectors are sealed with O-shaped or specially-made mountain-shaped sealing rings, but it is necessary to make a stepped sealing groove on the corresponding chassis to match with it. The sealing effect of the O-ring depends on the correct matching of the size of the O-ring and the size of the sealing groove, and the corresponding amount of compression and stretching of the ring is required. If the compression amount of the O-ring is too small, it will cause leakage; if the compression amount is too large, it will cause the rubber stress of the O-ring to relax and leak. In addition, if the O-ring is excessively stretched during operation, it will accelerate aging and cause leakage.
