Abstract
Abstract A lock connector for normally biasing a flexible lock piece in the upward direction includes a short circuit electrode disposed on the upper surface of a female connector housing. Two lock detecting electrodes are held at positions in a male connector housing by the elastic restoring action of the flexible lock piece. Thus, a restoring operation of the flexible piece and short-circuiting between the cooperating terminals can simultaneously be achieved without any deviation from the correct timing relationship established among the components.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
178 words
A lock connector comprising: first connector housing having a flexible lock piece formed thereon; second connector housing having an engagement portion formed thereon to be engaged with said flexible lock piece; a detecting member for detecting the locked state between the first and second connector housings, said detecting member comprising: a pair of lock detecting electrodes disposed on said second connector housing where said flexible lock comes in contact with said engagement portion, and a short circuit electrode disposed on the upper surface of said first connector housing where said flexible lock piece is urged toward said engagement portion, said short circuit electrode electrically connecting said pair of lock detecting electrodes when said flexible lock piece is engaged with said engagement portion in said locked state; and a U-shaped leaf spring including a first leg contacting the flexible lock piece, a second leg contacting a side of said first housing, and a connection portion connecting the first and second legs, said connection portion being adjacent a distal free end of the flexible lock piece in said locked state.
Claim 2
Dependent Claim
178 words
A lock connector comprising: first connector housing having a flexible lock piece formed thereon; second connector housing having an engagement portion formed thereon to be engaged with said flexible lock piece; a detecting member for detecting the locked state between the first and second connector housings, said detecting member comprising: a pair of lock detecting electrodes disposed on said second connector housing where said flexible lock comes in contact with said engagement portion, and a short circuit electrode disposed on the upper surface of said first connector housing where said flexible lock piece is urged toward said engagement portion, said short circuit electrode electrically connecting said pair of lock detecting electrodes when said flexible lock piece is engaged with said engagement portion in said locked state; and a U-shaped leaf spring including a first leg contacting the flexible lock piece, a second leg contacting a side of said first housing, and a connection portion connecting the first and second legs, said connection portion being adjacent a distal free end of the flexible lock piece in said locked state.
Claim 3
Dependent Claim
26 words
A lock connector as claimed in claim 1, wherein one of said first and second connector housings is fixedly secured to a member to be mounted.
Claim 4
Dependent Claim
25 words
A lock connector as claimed in claim 1, wherein said U-shaped leaf spring and said pair of short circuit electrode portions comprise an integral unit.
Claim 5
Dependent Claim
88 words
A lock connector as claimed in claim 1, wherein said second connector housing includes a partition wall extending toward the flexible lock piece of said first connector housing so that said pair of lock detecting electrodes are disposed with said partition wall interposed therebetween, and said first connector includes an engagement hole for receiving a part of said partition wall in engagement with said engagement hole at the position located opposite to said partition wall while said flexible lock piece is brought in contact with said engagement portion.
Claim 6
Dependent Claim
107 words
A lock connector comprising: a first connector housing having a generally U-shaped, metallic flexible lock piece formed thereon, one end of the metallic flexible lock piece being fixably connected to the first connector housing; a second connector housing having an engagement portion disposed therein to be engaged with said metallic flexible lock piece; and a pair of lock detecting electrodes formed on said second connector housing where said metallic flexible lock piece comes into contact with said engagement portion, wherein said metallic flexible lock piece is electrically connected to said pair of lock detecting electrodes when said metallic flexible lock piece is engaged with said engagement portion.
Claim 7
Dependent Claim
107 words
A lock connector comprising: a first connector housing having a generally U-shaped, metallic flexible lock piece formed thereon, one end of the metallic flexible lock piece being fixably connected to the first connector housing; a second connector housing having an engagement portion disposed therein to be engaged with said metallic flexible lock piece; and a pair of lock detecting electrodes formed on said second connector housing where said metallic flexible lock piece comes into contact with said engagement portion, wherein said metallic flexible lock piece is electrically connected to said pair of lock detecting electrodes when said metallic flexible lock piece is engaged with said engagement portion.
Claim 8
Dependent Claim
36 words
A lock connector as claimed in claim 5, wherein said second connector housing includes a engagement projection projecting between said pair of lock detecting electrodes toward the metallic flexible lock piece of said first connector housing.
