Abstract
Abstract A connector inspecting device that positively determines whether a metal terminal has been correctly inserted into the housing of the connector includes a slider provided in a checker housing in such a manner that it is movable and urged toward a connector by a compression spring. The slider includes a lance check pin protruded toward the connector and an electrical contactor that is integral with the lance check pin. When the connector is at a "normal position," the lance check pin goes in a lance bending space provided for a lance, so that the electrical contactor is electrically connected to the metal terminal. In the case where the metal terminal is set at a "half insertion position," the lance check pin abuts against the lance, which prevents the contact of the electrical contactor with the metal terminal.
