Strain relief device for electrical cable connector assembly

摘要

An electrical cable connector assembly includes a connector and a cable. The connector includes a housing enclosing an insulator with contacts fixed thereto. The cable has a number of wires with leads electrically connected to the contacts. A plastic strain relief is fixedly attached to the cable by insert molding, and has two keys engagably received within two grooves defined by the housing. A metal strain relief is formed by stamping a metal sheet to have a hollow body portion and two fitting wings extending from opposite sides thereof. The body portion is crimped to be fixedly connected to the cable near the plastic strain relief. The wings are fittingly received between a stop wall and either a connecting post or sleeve formed on a lower housing member of the housing. Through cooperation between the metal and plastic strain reliefs, a large withdrawal force acting on the cable relative to the connector can be effectively transmitted to the housing to prevent the withdrawal force from affecting the leads of the cable.
