Electrical connector with binding detection unit

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and relates to a pair of electrical connectors with the function of detecting whether the matching between the electrical connectors is complete. Background technique [0002] The connector having the joint detection unit disclosed in Patent Document 1 is configured such that when one connector is inserted into the other connector, when the contact part is not completely accommodated in the receiving space, the action piece is moved by the width through the guide piece. Press the contact piece in the direction away from the center of the receiving space, thereby preventing the contact part from contacting the contact point. When the contact part is completely accommodated in the receiving space, the action piece is disengaged from the guide piece to the reverse mating direction of the first connector. Open, so that the contact piece is about to return to the original position, and t...

Problems solved by technology

In addition, in the electrical connectors disclosed in Patent Documents 4 to 6, since a dedicated mechanism for detecting conduction is additionally provided in addition to the signal contacts, the space occupied by the electrical connector becomes correspondingly larger, and, Since a circuit dedicated to conduction detection is also required, the number of components increases accordingly and the cost increases, but such a problem does not occur in the connector described in the above-mentioned Patent Document 1.
