ABSTRACT:
A double-retaining connector in which a double-retaining operation can be effected easily and positively and a retaining portion will not be inadvertently influenced by an external force. A spacer 2 is inserted into terminal receiving chambers 4 from a rear end of a housing 1, and each spacer piece 16 at a front end of the spacer 2 moves past a retaining projection 5a of a retaining lance 5, and is held in a provisionally-retained position forwardly of the retaining lance 5. Then, a connection terminal 3 is inserted into the terminal receiving chamber 4 from the rear end of the housing 1, and moves past a retaining protuberance 6 to be retained against rearward withdrawal. At the same time, the retaining projection 5a of the retaining lance 5 fits in a retaining hole in an electrical contact portion of the connection terminal 3, thereby achieving a double retaining of the connection terminal. Finally, the spacer 2 is partially pulled out in a direction opposite to the direction of insertion of the connection terminal, so that the spacer piece 16 sits in a flexing space beneath the retaining lance 5, thereby completely retaining the spacer. As a result, the flexing of the retaining lance 5 is prevented, and the connection terminal 3 is positively and doubly retained within the terminal receiving chamber 4.
