Patent ID: 8336196

Claim:
A connector assembling jig which is to be used to determine whether terminal fittings have been inserted to proper positions in a housing, the housing including a main body with terminal accommodating portions and locking pieces for locking and retaining the terminal fittings inserted respectively to the proper positions in the terminal accommodating portions and formed so that each locking piece projects out from one side surface of the main body if the corresponding terminal fitting is inserted insufficiently in the terminal accommodating portion, and holds the housing and enables detection of insufficient insertion of the terminal fittings when the terminal fittings are inserted into the housing, the jig comprising: a base formed with a holder accommodating portion; a holder including an accommodating recess for accommodating and positioning the housing, the holder being mounted in the base and being slidable therein along a sliding direction between a first position where the holder is partially inserted into the holder accommodating portion and a second position where the holder is fully inserted into the holder accommodating portion; an insufficient insertion detection arm supported in the holder for rotation about a supporting shaft transverse to the sliding direction so that the detection arm is displaceable between an insufficient insertion detecting state for locking the holder at the second position when any locking piece of the housing projects out from the one side surface of the main body and a non-detecting posture enabling the holder to slide toward the first position; at least one positioning groove formed in an inner side surface of the accommodating recess and adapted to receive at least one positioning rib projecting in a thickness direction of the housing, an inner surface of the positioning groove being substantially flush and continuous with an inner side surface of the accommodating recess adjacent to the inner side surface where the positioning groove is formed.
