Abstract
Abstract An electrical connector (4) terminated to signal wires (SW) of a shielded electrical cable (C) having a drain wire (DW), has an insulating housing (8) containing electrical terminals having contacts (40) electrically connected to the signal wires of the shielded electrical cable (C). A metal shield (14) covering the lower part of the housing (8) has a grounding clip (48) connected to the rear wall (28) of the shield (14) by means of a strap (62). The grounding clip receives an end portion of the cable (C) from which the signal wires (SW) extend to the contacts (40) of the connector (4). The drain wire (DW) is wound in a circuitous path about tabs (58) of the grounding clip (48). The grounding clip can be bent about the strap (62) to line in a channel (36) between two rows of the contacts (40) of the connector (4), after the grounding clip has been wound about with insulative tape (T). The drain wire (DW) accordingly provides strain relief, if the cable (C) is inadvertently pulled, for the electrical connections between the contacts (40) and the signal wires (SW).
