Abstract
Abstract In a connector, a locking connection detection member is beforehand attached to a rear portion of a male connector housing and is retained thereto by resilient retaining pieces of the locking connection detection member in such a manner that the locking connection detection member is extended rearwardly from the male connector housing. Engagement release projections for the resilient retaining pieces are provided on the female connector housing so that when the male and female connector housing are completely connected together with the lock arm engaged with the engagement portion, the engagement release projections release the retaining of the resilient retaining piece, thereby enabling the removal of the locking connection detection member. According to this arrangement, a complete connection of a connector can be detected easily.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
124 words
A connector locking connection detection device comprising: a pair of first and second connector housings to be connected to each other; first means for locking the connection between said connector housings; and second means for notifying the locking by the first means, including: a locking connection detection member; engagement means for engaging said locking connection detection member with said first connector housing to retain said locking connection detection member onto said first connector housing; and releasing means for releasing the engagement between said locking connection detection member and said first connector housing when the connection between said connector housings is locked by said first means, to thereby enable the removal of said locking connection detection member to notify the locking by the first means.
Claim 2
Dependent Claim
