ELECTRIC WIRE-TO-SUBSTRATE CONNECTOR

摘要

A plug side surface (50a) of a plug housing (5) is provided with a claw portion (53). The claw portion (53) includes a plug lock surface (60) facing in a direction away from a connector mounting surface (10a). Each assistant fitting (9) of a receptacle connector (3) includes a receptacle lock surface (38) that faces in a direction approaching the connector mounting surface (10a) and is opposed to the plug lock surface (60) in a mated state. The plug lock surface (60) includes a lock maintaining surface (65) and an unlocking surface (66). Assuming that an angle formed between a reference plane (Q) and the lock maintaining surface (65) is a lock maintaining angle (¸1) and an angle formed between the reference plane (Q) and the unlocking surface (66) is an unlocking angle (¸2), the lock maintaining angle (¸1) is smaller than the unlocking angle (¸2).
