ABSTRACT:
A connector couple has an engagement checking structure including a first connector housing having a resilient lock arm and a second connector housing having an engagement portion for receiving to the resilient lock arm. On the resilient lock arm of the first connector housing, a short-circuit contact piece is provided, while, on the engagement portion of the second connector housing, a couple of terminal pins for detecting engagement are provided such that the terminal pins are positioned outside of both sides of the resilient lock arm when the first connector housing has engaged with the second connector housing so that, when the first connector housing has completely engaged with the second connector housing and the resilient lock arm has returned to its original position, the short-circuit contact piece makes electric connection with the terminal pins.
