Abstract

Coaxial cables made up a plurality of co-planar individual coaxial cables, each having a signal wire and a coaxial conductive sheath including a ground wire co-planar with the signal wires, are terminated by inserting the end of the cable in a housing for receiving an array of insulation displacement contacts along an axis transverse to the plane of the cable. Each signal wire and each ground wire is electrically contacted by a respective one of the insulation displacement contacts. The cable is secured to the housing, and the housing is secured to the structure which supports the contacts.

Claims

1. A method for mechanically and electrically attaching a cable termination to the end of a cable assembly having (1) a plurality of co-planar, parallel, laterally spaced signal wires, each signal wire being enclosed in a first insulating sheath and having (a) an associated parallel ground wire in the plane of the signal wires outside the first insulating sheath and (b) a conductive sheath surrounding the ground wire and the first insulating sheath, and (2) a second insulating sheath surrounding all of the conductive sheaths, the ends of the conductive sheaths being recessed from the ends of the signal wires, the method comprising the steps of:

inserting the end of the cable assembly in a first housing member;

securing the cable assembly to the first housing member;

bringing the first housing member together with a second housing member having a plurality of parallel, laterally spaced insulation displacement contacts extending from the second housing member in two parallel rows, the insulation displacement contacts in one row being signal wire contacts for respectively electrically contacting the signal wires, and the insulation displacement contacts in the other row being ground wire contacts for respectively electrically contacting the ground wires, the first and second housing members being brought together by relative motion of the housing members along a termination axis transverse to the plane of the signal wires and parallel to the insulation displacement contacts so that each signal wire contact displaces the insulation surrounding a respective one of the signal wires beyond the end of the associated conductive sheath and makes electrical contact with that signal wire, and so that each ground wire contact displaces the insulation and conductive sheath surrounding a respective one of the ground wires and makes electrical contact with that ground wire; and

securing the first and second housing members together.

2. The method of claim 1 wherein the cable assembly is inserted into the first housing member along an axis parallel to the signal wires.

3. The method defined in claim 1 wherein the first and second housing members are brought together with the rows of insulation displacement contacts parallel to the end of the cable assembly.

4. The method defined in claim 1 wherein the first and second housing members are brought together with only the signal wire contacts being beyond the recessed ends of the the conductive sheaths.

5. The method defined in claim 1 wherein the termination axis is perpendicular to the plane of the signal wires.

6. The method defined in claim 1 wherein the termination axis forms an angle of approximately 105°

with the plane of the signal wires.

7. The method of claim 1 further comprising the step of applying an adhesive to at least one of the cable assembly and the first housing member prior to the inserting step so that the adhesive joins the cable assembly and the first housing member subsequent to the inserting step, and so that the cable assembly and the first housing member are secured to one another by allowing the adhesive to cure.
