ABSTRACT:
A double-lock type connector includes a housing having a pair of locking lances for locking a terminal, and a holder having a pair of locking arms for locking the terminal when inserted into the housing. The housing has a pair of guide paths into which the pair of locking arms advance, and a pair of paths continuous with the pair of guide paths. While the holder is in the temporarily locked position where the locking arms are out of engagement with the terminals, a lance-unlocking tool is inserted into the housing form an opening on one side of the housing and an arm-unlocking tool is inserted into the housing from an opening on the other side of the housing. Thus, the locking lances and locking arms are both out of engagement with the terminal. The locking arms are at the guide paths when the holder is in the temporarily locked position. The arm-unlocking tool has a pair of prongs that goes into contact with the pair of locking arms when inserted into the housing. The arm-unlocking tool has a pair of prongs that goes into contact with the surface of the locking arm facing the terminal when inserted into the housing. The arm-unlocking tool is then pulled out of the housing together with the wires connected to the terminals, while the prongs of the arm-unlocking tool urging the locking arms to deflect away from each other.
