  • Electric connector having a lance supported by a resilient support with a slit and disengageable by a jig
    Patent number: 9231333
    Abstract: An electric connector includes an electrically insulative housing, and a terminal having an engagement section and inserted into a terminal space formed in the housing in a direction from a rear towards a front of the housing. The housing includes a lance protruding in the housing towards an axis of the terminal space, and is able to engage to and disengage from the engagement section of the terminal. A resilient support resiliently supports the lance such that the lance is able to move away from the axis, and a path is provided through which a jig for disengaging the lance from the engagement section is inserted into the housing through a front of the housing towards the lance along the engagement section. The resilient support is formed with a slit communicating with the path and extending towards the lance from an entrance of the path.
