ELECTRICAL CONNECTOR

PROBLEM TO BE SOLVED: To improve the damping factor of a noise component by providing one or more outward projections on the side surface of a conductive shielding case electrically connected to a grounding electrode of an internally installed filter unit and covering a holder on the opposite side of the fitting side with a mating connector. SOLUTION: A conductive shielding case 8 covering one side surface or more of a holder 7 holding a contact element 4 installed in response to a filter element 3 such as a diode, a resistance, ferrite or a capacitor formed in a filter unit 1, is electrically connected at multipoint to a grounding electrode 2. On the outside of the shielding case 8, one or more springy projections 9 are formed over in the lengthwise directional whole projection shapes, partially embossed plural projection shapes or partially punched plural tongue piece shapes. As a result, an electrical passage among the grounding electrode 2, the shielding case 8 and an installing chassis is shortened to reduce impedance to quickly and surely transmit noise energy absorbed by the filter element 3.
