Title: Electrical continuity checker for connector

Abstract: A continuity sensing pin movable forward and backward has one end for contacting a terminal of a connector. An insertion inspecting pin has one end insertable into a deflection space of a flexible locking arm that locks the terminal in a housing of the connector. An electrically conductive slide is resiliently urged toward the terminal of the connector. The continuity sensing pin has an opposing end contacting a circuit conductor via a resilient member. The circuit conductor can contact the slide. The insertion inspecting pin has an opposing end that can abut against the slide. When the slide is energized by an external power source and the one end of the insertion inspecting pin abuts against the flexible locking arm, the opposing end of the insertion inspecting pin pushes the slide to disengage the slide from the circuit conductor. The circuit conductor is arranged on a circuit board. The circuit board has a through hole passing the opposing end of the insertion inspecting pin. The circuit conductor has a front part disposed on a front face of the circuit board and a rear part disposed on a rear face of the circuit board. The front part electrically communicates with the rear part via the through hole. The front part of circuit conductor can contact the resilient member and the rear part of the circuit conductor can contact the slide.
