AI Technical Summary
Existing connector housings suffer from low connection strength, are easily damaged, and allow dust to easily enter.
The inner shell is inserted into the outer shell. The design of the retaining ring and retainer increases the contact area and prevents loosening. The combination of external and internal threads, along with the structure of elastic elements and positioning blocks, ensures a stable connection between the inner shell and the outer shell.
It improves the connection strength of the connector housing, prevents stress concentration and loosening, reduces dust ingress, and enhances the stability and durability of the connector.
