Abstract
Description
Technical Field
[0001] This utility model relates to a connector housing and a connector including the connector housing. Background Technology
[0002] In existing technologies, many connectors employ a chain hook structure, linking multiple connectors together in a string to facilitate packaging and subsequent crimping operations. During the crimping process at the user end, the linked connectors need to be unhooked using crimping equipment before proceeding to the next crimping step. Stringed connectors facilitate automated transport, significantly improving the efficiency of automated crimping equipment. However, in existing technologies, chain hook breakage occurs during connector unhooking, severely impacting the efficiency of automated crimping equipment. The cause of chain hook breakage lies in the lack of elasticity in the chain hook's locking structure; the hook relies on hard friction for unhooking, resulting in high unhooking force and severe stress concentration at the hook root. Furthermore, the condition of the connector and the climate differences of the usage location can occasionally exacerbate the chain hook breakage problem. Utility Model Content
