Abstract: PURPOSE: A connector is provided to prevent a clearance between a contact and an insulator, to smoothly combine a double locking member with the contact and to simplify the structure. CONSTITUTION: In a temporary locking state, a clearance exists between an end wall of a contact hole at an insulator(1) and an end surface of a contact(2). When a double locking member(4) is pushed down from a temporary locking position to a regular locking position, an engaging portion(4B) of the double locking member pushed an inclined plane(2C) of a second stabilizer(2B) of the contact. Therefore, the contact moves to the forward direction. When the end surface of the contact is brought into contact with the end wall of the contact accommodating chamber, the contact stops. Then, the clearance becomes naught. Since the contact of the connector cannot move to the insulator, contacts of the connector and a mating connector stably comes into contact with each other.
