PROBLEM TO BE SOLVED: To provide electric connectors that comprise a detection function of complete fitting, can make both electric connectors compact, improve the installation number of contacts and the freedom of installation positions, and improves manufacturing efficiency and the freedom of material selection without requiring a circuit exclusively for conduction detection.SOLUTION: An electric connector includes coupling detection means which is configured that, in an insertion process, from before a contact part 222 contacts with a contact point 122a until insertion length L of the contact part to a passage space 121a reaches a setting value L1 for an insertion process, a wide part 231 of a second plate 230 pushes a guide protrusion piece 122b out to the width direction outer side, elastically deforms a first plate 122 to the width direction outer side of the passage space, ousts the contact point from the passage space, and blocks contact between the contact part and contact point, and when the insertion length exceeds the setting value for the insertion process, the wide part passes the guide protrusion piece to an opposite fitting side, the first plate deviates to the width direction inner side by its restitutive force, and the contact between the contact part and contact point starts. |
