A connector includes a first connector housing having a resiliently deflectable lock arm in an outer wall of the first connector housing and a second connector housing having a lock arm engaging with a locking piece fitted in the first connector housing. In the complete engaged state of the pair of connector housings, the lock arm engages with the locking piece so that the first and second connector housings are secured to each other. The connector further includes an engagement confirming member movably attached to the lock arm and an engagement retaining wall standing and positioned adjacently to the engagement confirming member. In the complete engagement of the pair of connector housings, the engagement confirming member is moved onto a top portion of the engagement retaining wall to prevent the lock arm from deflecting. The engagement confirming member is preferably attached movably in a substantially orthogonal direction to the engagement direction of the connector housings. |

DETAILED DESCRIPTION In view of the above-mentioned drawback, a subject of the present invention is to provide a connector equipped with an engagement confirming mechanism that can easily confirm a complete engaged state of mating connector housings and is suitable for miniaturization design of the connector housing particularly regarding connectors accommodating only a few terminals.
For achieving the subject, in the present invention, a connector includes a first connector housing having a resiliently deflectable lock arm in an outer wall of the first connector housing, a second connector housing having a lock arm engaging with a locking plate fitted in the first connector housing, wherein, in the complete engaged state of the pair of connector housings, the lock arm engages with the locking plate so that the first and second connector housings are secured to each other, an engagement confirming member movably attached to the lock arm, and an engagement retaining wall standing and positioned adjacently to the engagement confirming member, wherein, in the complete engagement of the pair of connector housings, the engagement confirming member is moved onto a top portion of the engagement retaining wall to prevent the lock arm from deflecting.
The engagement confirming member is preferably attached movably in a substantially orthogonal direction to the engagement direction of the pair of connector housings.
Preferably, a projecting plate portion is provided in a free end of the lock arm and the engagement confirming member is formed with a guide wall having a guide groove, the projecting plate portion inserted into the guide groove so that the engagement confirming member may be movable along the projecting plate portion.
Advantageously, a locking projection is provided in the guide wall of the engagement confirming member and the projecting plate portion is formed with a recess engaging with the locking projection.
