Abstract:
1. An electrical connector comprising: a first connector including a first connector housing with a first latch part provided on a peripheral wall surface of said first connector housing; a second connector including a second connector housing with a portion defining an inserting hole into which said first connector housing is fitted provided inside said second connector housing; and a connector position assurance for detecting a fitted state of said first and second connectors; said first latch part of said first connector including a pair of a first latch protrusion and a second latch protrusion arranged with a space therebetween in a direction in which said first connector housing is fitted, said second connector including an elastically deformable latch arm in said inserting hole of said second connector housing with a predetermined space from one inner wall surface of said second connector housing, said latch arm extending in a direction in which said second connector is fitted and having a latch pawl at an end of said latch arm, said connector position assurance including: said attaching part of said connector position assurance being fixed to said second connector housing; said first and second finger pieces of said connector position assurance being fitted slidably in a fitted direction into a space between said elastic latch arm and said one inner wall surface; if said first and second connectors are fitted, said first latch protrusion of said first connector reaches said second bent protrusion of said connector position assurance to make said connector position assurance slide backward and to accumulate spring force in said spring-force-accumulated part; if a regular fitted state is achieved, said second latch protrusion latches onto said latch pawl of said elastic latch arm by means of spring recoil strength of said spring-force-accumulated part, and said first bent protrusion of said connector position assurance abuts said one inner wall surface to lock movement of said elastic latch arm.
