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 lie 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).

Connecteur électrique (4) aboutissant aux fils du signal (SW) d'un câble électrique blindé (C) ayant un fil de masse (DW). Comprend un boîtier isolant (8) contenant des bornes électriques qui ont des contacts (40) connectés aux fils du signal dudit câble (C). Un écran métallique (14) couvrant la partie inférieure du boîtier (8) est doté d'une pince de mise à la terre (48) connectée à la paroi arrière (28) de l'écran (14) au moyen d'un cavalier (62). La pince reçoit une extrémité du câble (C) d'où partent les fils du signal (SW) pour rejoindre les contacts (40) du connecteur (4). Le fil de masse (DW) est entortillé autour des pattes (58) de la pince (48). Après avoir été recouverte de ruban isolant, la pince peut être pliée près du cavalier (62) de façon à occuper un canal (36) séparant deux rangées de contacts (40) du connecteur (4). Le fil de masse (DW) protège la connexion électrique entre les contacts (40) et les fils du signal (SW), au cas où le câble (C) serait tiré par accident.
