A lock detection structure of a connector, includes: a first connector housing (63) having a connector lock projection (65); a second connector housing (39) having a deformable lock arm (49); and a lock detecting member (33, 83) for detecting whether the connector lock projection is locked with the deformable lock arm. The lock detecting member is composed of at least one deformable detection arm (69, 71; 87), at least one engage projection (77, 93) engaged with the deformable lock arm when the lock detecting member is engaged with the second connector housing, and at least one disengage projection (79, 95) formed also on the deformable detection arm (71, 87) at a position different from the at least one engage projection (77, 93) and dislocated from the deformable lock arm (49) by the connector lock projection (65) of the first connector housing (63) to disengage the engage projection (77, 93) from the deformable lock arm (49) when the first connector housing (63) is engaged with the second connector housing (39). |

DETAILED DESCRIPTION With these problems in mind therefore, it is the object of the present invention to provide a lock detection structure of a connector, which can detect the locking condition of the male and female connectors securely, without damaging the lock detecting member.
To achieve the above-mentioned object, the present invention provides a lock detection structure of a connector, including: a first connector housing (63) having a connector lock projection (65); a second connector housing (39) having a deformable lock arm (49) formed integral with the second connector housing; and a lock detecting member (33, 83) for detecting whether the connector lock projection of said first connector housing is locked with the deformable lock arm of said the second connector housing, said lock detecting member being formed with: at least one deformable detection arm (69, 71; 87); at least one engage projection (77, 93) formed on said deformable detection arm (69, 87) and engaged with the deformable lock arm of said second connector housing when said lock detecting member is engaged with said second connector housing; and at least one disengage projection (79, 95) formed also on said deformable detection arm (71, 87) at a position different from said at least one engage projection (77, 93) and dislocated from the deformable lock arm (49) by the connector lock projection (65) of said first connector housing (63) to disengage said engage projection (77, 93) from the deformable lock arm (49) when said first connector housing (63) is engaged with said second connector housing (39).
Further, the deformable lock arm (49) is formed with: a pair of deformable arms (51) formed integral with said second connector housing (39); and an intermediate lock projection (55) formed by bridging said two deformable arms at a middle portion thereof and engaged with the connector lock projection (65) of said first connector housing (63).
Further, the locking direction between said first and second connector housings (63, 39) is different from engage direction between said second connector housing (39) and said lock detecting member (33)
