UNLOCKING DEVICE, CONNECTOR DEVICE, AND CONNECTOR

摘要

[Problem] To prevent a receptacle connector and a plug connector from being erroneously released from a state locked to each other by hand, and to make it possible to easily remove the plug connector from the receptacle connector by an operator alone. [Solution] A receptacle housing 4 of a receptacle connector 3 is provided with through holes 411. A plug housing 7 of a plug connector 6 is provided with protrusions 92 which can be engaged in the though holes 411, and leaf springs 711 which urge the protrusions 92 toward the through holes 411. An unlocking jig 9 is formed by a jig main body 91 which can be mounted and removed to and from the receptacle housing 4 of the receptacle connector 3 in a direction D2 perpendicular to a fitting and removing direction D1, and the protrusions 92 which are provided on the jig main body 91 and press lugs 712 against an urging force of the leaf springs 711 when the jig main body 91 is mounted to the receptacle connector 3 to thereby disengage the lugs 712 and the through holes 411.
