Patent ID: 8220133

Claim:
A method of attaching an electric cable, covered with a sheath made of a thermodeformable plastic, to an electronic circuit housing, comprising the following steps: stripping one end of the cable and fitting onto the stripped end of the cable a rigid bushing comprising a hollow body, the inside diameter of which accepts the conductors but not the sheath of the cable, the bushing having one end provided with a protruding collar, fitting the one end of the cable and the one end of the bushing into a heatable mold comprising a slightly conical interior surface part of a diameter smaller than that of the collar and a cylindrical part of a diameter larger than the largest diameter of the conical part, heating the mold to a temperature at which the material of the sheath will soften, driving the bushing in the mold, in the direction of the axis of the cylindrical part, so that the body of the bushing becomes inserted between the conductors of the cable and the softened sheath, the collar of the bushing upsetting the thermodeformable plastic of the sheath to the point that it fills the conical part of the mold, cooling, in order to solidify the sheath, extracting said one end of the cable from the mold, said one end having a conical sheath portion of increasing diameter ending with the protruding collar, inserting another end of the cable, from inside the housing, through an opening in the housing, the diameter of which is very slightly smaller than the largest diameter of the conical sheath portion, and closing the housing.
