ABSTRACT:
A short-circuit chamber 15 is provided in a female connector housing 11, and contains a short-circuit part 16 provided with left and right-hand resilient arms 18a which normally make contact with female terminal parts 13 to establish a conducting state. A male connector housing 21 is provided with insulating pieces 25 which, when the male and female housings are coupled, enter between the female terminal parts 13 and resilient arms 18a to break the electrical circuit. Projections 18c engage with the rear edges 15d of openings 15c to establish an engaged state of the short-circuit part 16. Insertion of the insulating pieces 25 disengages the projections 18c from the rear edges 15d, to allow the short-circuit part 16 to be taken out.
