Abstract

A strain relief for a coaxial cable and coaxial connector interconnection is provided as an injection moldable polymer material surrounding the interconnection. The injection moldable material fills a solder pre-form cavity between an outer conductor of the coaxial cable and an inner diameter of a bore of the connector body, strengthening and environmentally sealing the interconnection.

First claim

We claim:

1. A strain relief for coaxial cable and coaxial connector interconnection, wherein the interconnection comprises a coaxial cable having an outer conductor and a coaxial connector having an outer connector body having an inner diameter; the outer conductor being soldered to the outer connector body at a solder joint, the strain relief comprising;
an injection moldable polymer material surrounding the interconnection;
the injection moldable material filling a solder pre-form cavity between the outer conductor of the coaxial cable and the inner diameter of the outer connector body adjacent the solder joint.

2. The strain relief of claim 1 , wherein the injection moldable polymer material is polyamide material.

3. The strain relief of claim 1 , wherein the polymer material is provided with a cable portion provided with a plurality of stress relief grooves.

4. The strain relief of claim 3 , wherein the stress relief control grooves are generally elliptical, with a major axis of the stress relief grooves arranged normal to a longitudinal axis of the coaxial connector.

5. The strain relief of claim 3 , wherein the extended cable portion extends along the coaxial cable a distance greater than three diameters of the coaxial cable.

6. The strain relief of claim 1 , wherein the strain relief surrounding the coaxial connector is seated upon a strain relief portion of the outer connector body of the coaxial connector.

7. The strain relief of claim 6 , wherein the strain relief portion is provided with a plurality of retention features.

8. The strain relief of claim 7 , wherein the retention features are non-cylindrical raised segments.

9. The strain relief of claim 6 , wherein the strain relief portion abuts a tool face portion of the outer connector body of the coaxial connector.

10. The strain relief of claim 7 , wherein the retention features are annular grooves.
