Abstract

Abstract A connector comprises a female connector housing having a flexibly deformable lock arm, a male connector housing having a lock portion elastically engageable with the lock arm when the two connector housings are completely engaged with each other, and a lock holding member rotatably mounted at an end of the lock arm. The lock holding member is selectively movable between an unlock position to allow the lock arm to be flexed in an unlocking direction thereof and a lock position to inhibit the lock arm to be flexed in the unlocking direction. In the complete engagement state, if a lock holding member in the end of the lock arm is rotated from an unlock position to a lock position, then the lock arm is prevented from being deformed flexibly to thereby be able to keep on the locking state of the connector. On the other hand, when the female and male connector housings are in incomplete engagement with each other, the lock arm is on the way to its flexible deformation. In this state, since the lock holding member is unable to advance into the flexing side of the lock arm, an operator can know that the female and male connector housings are in incomplete engagement with each other, in accordance with the fact that the lock holding member cannot be shifted to the lock position.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 110 words
A connector comprising: a first connector housing having a flexibly deformable lock arm; a second connector housing having a lock portion elastically engageable with said lock arm when the two connector housings are completely engaged with each other; and a lock holding member rotatably mounted on said first connector housing, said lock holding member being movable between an unlock position to allow said lock arm to be flexed in an unlocking direction thereof and a lock position to inhibit said lock arm to be flexed in the unlocking direction; wherein the lock holding member is positioned below the lock arm when the lock holding member is in the lock position.
Claim 2
Dependent Claim 110 words
A connector comprising: a first connector housing having a flexibly deformable lock arm; a second connector housing having a lock portion elastically engageable with said lock arm when the two connector housings are completely engaged with each other; and a lock holding member rotatably mounted on said first connector housing, said lock holding member being movable between an unlock position to allow said lock arm to be flexed in an unlocking direction thereof and a lock position to inhibit said lock arm to be flexed in the unlocking direction; wherein the lock holding member is positioned below the lock arm when the lock holding member is in the lock position.
Claim 3
Dependent Claim 68 words
A connector as claimed in claim 1, wherein said lock holding member is rotatably mounted on a free end side of said lock arm and is structured such that, when it is situated at said unlock position, a lock indication portion formed in the free end portion of said lock arm is covered and, when it is situated at said lock position, said lock indication portion is exposed.
Claim 4
Dependent Claim 47 words
A connector as claimed in claim 2, wherein said lock arm includes a mounting portion to which the lock holding member is mounted, said mounting portion of which a back surface is an arc shape and a front surface is a cut-down shape at almost right angle.
Claim 5
Dependent Claim 28 words
A connector as claimed in claim 2, wherein said lock indication portion is colored with a different color from the remaining portions of the first and second housings.
Claim 6
Dependent Claim 35 words
A connector as claimed in claim 3, wherein said mounting portion includes a shaft which is integrally formed on the side surface of the mounting portion, to which said lock holding member is rotatably mounted.
Claim 7
Dependent Claim 28 words
A connector as claimed in claim 3, wherein said lock holding member has an arc shaped inner surface which corresponds to the back surface of the mounting portion.
Claim 8
Dependent Claim 19 words
A connector as claimed in claim 1, wherein said lock holding member is separate from said deformable lock arm.
