Abstract

A method for forming a waterproof ring comprises that following steps: S01, providing a shell with a waterproof groove; S02, dispensing glue along the waterproof groove to form a waterproof ring by using a glue dispensing device; S03, drying the waterproof ring on the housing. The present application has higher waterproofness and lower manufacturing cost.

Description

technical field [0001] The present application relates to the field of electrical connectors, in particular to a method for forming a waterproof ring, a connector shell and a connector. Background technique [0002] Mobile devices have more and more demands for waterproofing, and the casing of the mobile device must be equipped with some interfaces to connect external devices, such as USB interface, Audio Jack, SIM card holder, etc.; and these connection interfaces need to be waterproofed, otherwise, mobile The device is not waterproof. [0003] The existing waterproof scheme is generally carried out by adopting the method of setting a waterproof ring, that is, the silicone waterproof ring is formed first, and at the same time, a groove structure for accommodating the waterproof ring is provided on the outer shell of the connector. When this structure is installed, the waterproof ring is easy to fall off, and the cost of manufacturing and assembling the silicone waterproof ...
