Appl. No.:

09/791829

Inventors:

Ping Chen - West Bloomfield MI

Assignee:

J.S.T. Mfg. Co., Ltd. - Osaka

International Classification:

H01R 13627

US Classification:

439358, 439357

Abstract:

A structure for interlocking connectors improves rigidity of a push lever as well as mutual retention and mechanical strength to a proper extent, and increases the feeling of click when they are engaged with each other, further protecting the lever to be caught by foreign wire ends. The connectors are a male connector ( ) and a female connector ( ) to be fitted on the male connector, and a lockable lug ( ) is formed on the outer surface of one of connector housings ( ). A lock arm ( ) integral with a pawl ( ) engaging with the lockable lug ( ) is secured above the outer surface of the other connector housing ( ), by a pair of elastically deformable hinge-shaped feet ( ). The push lever ( ) is disposed on a rear end of the lock arm ( ) extending rearwards beyond the feet ( ). The lever ( ) and a pair of bridging members ( ) continuing from opposite lateral ends of the lever and integrally fixed on side walls of the housing ( ) serve as an arch-shaped guard for the interlocking structure.
