Abstract

A connector assembly that includes an insulation displacement member including a hydrophobic organosilane mono-layer protective coating is disclosed. In one embodiment, the connector assembly may be manufactured by a method that includes assembling the connector assembly, contacting the connector assembly with an organosilane coating solution, and curing the organosilane coating solution. The connector assembly may be assembled by mechanically supporting the insulation displacement member with a connector framework. The connector assembly may be contacted with the organosilane coating solution by contacting at least the wire engaging portion of the insulation displacement member and at least a portion of the connector assembly with the organosilane coating solution.

First claim

What is claimed is:

1. A connector assembly comprising a connector framework and at least one insulation displacement member, wherein:
the connector framework comprises an insulated-wire passage that is sized and oriented to receive an insulated electrically conductive wire;
the insulation displacement member comprises a conductive wire engaging portion and is mechanically supported by the connector framework to permit forcible engagement of the wire engaging portion with the insulated electrically conductive wire to make electrical contact with a conductor therein, the conductive wire engaging portion of the insulation displacement member defining an electrically conductive path extending from the wire engaging portion to an electrical coupling node of the connector assembly;
at least the conductive wire engaging portion of the insulation displacement member is coated with a cured hydrophobic organosilane mono-layer protective coating.

2. The connector assembly of claim 1 , wherein the protective coating comprises an alkoxysilane.

3. The connector assembly of claim 1 , wherein the insulation displacement member is mechanically supported in a static or motive state.

4. The connector assembly of claim 1 , wherein the connector framework is not electrically conductive.

5. The connector assembly of claim 1 , wherein the connector framework comprises polycarbonate.

6. The connector assembly of claim 1 , wherein the connector framework is configured as a housing and the insulation displacement member is partially or entirely disposed within the housing.

7. The connector assembly of claim 1 , wherein only an exposed portion of insulation displacement member is completely coated and an unexposed portion of the insulation displacement member is not coated.

8. The connector assembly of claim 1 , wherein the insulation displacement member is coated on all surfaces.

9. The connector assembly of claim 1 , wherein the protective coating comprises an alkylsilane.

10. The connector assembly of claim 9 , wherein an alkyl functionality of the alkylsilane comprises a carbon chain having a length of greater than or equal to 8 carbons and less than or equal to 36 carbons.
