Abstract

An electrical connector including a housing and electrical conductor plating. The housing includes a first member and a second member. The first member is made of plastic and forms at least one first contact receiving channel therein. The second member is attached around the first member, and the first and second members form at least one second contact receiving channel therebetween. The electrical conductor plating is on the first member. The electrical conductor plating includes at least one first section along the at least one first contact receiving channel and at least one second section along an exterior side of the first member at the at least one second contact receiving channel. The first and second sections of the electrical conductor plating are electrically separate from one another.

First claim

What is claimed is:

1. An electrical connector comprising:
a support;
a plurality of elements held by the support, wherein each of the plurality of elements comprises:
a plastic housing; and
electrical conductor plating on surfaces of the plastic housing so as to form at least one signal transmission path through the plastic housing and a ground on an exterior surface of the plastic housing,
wherein the ground formed by the electrical conductor plating is configured to support current flowing parallel to the at least one signal transmission path through the plastic housing formed by the electrical conductor plating.

2. An electrical connector, comprising:
an insulative housing comprising at least one surface;
a first elongated section of electrically conductive plating disposed on a first surface of the at least one surface of the insulative housing; and
a second elongated section of electrically conductive plating disposed, parallel to the first elongated section, on a second surface of the at least one surface of the insulative housing,
wherein the first and second elongated sections are electrically separate, and
wherein the second surface extends around the first surface on at least two sides.

3. The electrical connector of claim 2 , wherein the first and second elongated sections of electrically conductive plating form a differential signal pair.

4. The electrical connector of claim 2 , wherein:
the insulative housing comprises two channels each defined by only three closed walls to form a first partially open C-shaped cavity and a second partially open C-shaped cavity;
the first elongated section is within the first partially open C-shaped cavity; and
the second elongated section is within the second partially open C-shaped cavity.

5. The electrical connector of claim 2 , further comprising:
a third section of electrically conductive plating disposed on an exterior surface of the insulative housing,
wherein the third section of electrically conductive plating is electrically separate from the first and second elongated sections.

6. The electrical connector of claim 2 , further comprising:
a metal component surrounding the insulative housing.

7. The electrical connector of claim 2 , wherein:
the first and second elongated sections of electrically conductive plating extend through an interior of the insulative housing.

8. An electrical connector, comprising:
an insulative housing;
a first elongated section of electrically conductive plating disposed on a surface of the insulative housing;
a second elongated section of electrically conductive plating disposed on a surface of the insulative housing;
a first mating interface portion electrically coupled to a first end of the first elongated section;
a second mating interface portion electrically coupled to a first end of the second elongated section,
a first mounting interface portion electrically coupled to a second end of the first elongated section; and
a second mounting interface portion electrically coupled to a second end of the second elongated section,
wherein each of the first and second mating interface portions is configured to make a separable electrical connection with an electrical conductor of a mating electrical connector; and
wherein each of the first and second mounting interface portions is configured for mounting to a surface of a printed circuit board.

9. The electrical connector of claim 8 , wherein the first and second elongated sections of electrically conductive plating are electrically separate.

10. The electrical connector of claim 8 , wherein the first and second mating interface portions each comprise a cavity configured to receive an electrical conductor of the mating electrical connector.

11. The electrical connector of claim 10 , wherein the cavities of the first and second mating interface portions are configured to deflect the one or more electrical conductors to generate a contact force.

12. The electrical connector of claim 8 , further comprising a third section of electrically conductive plating on an exterior surface of the insulative housing.

13. The electrical connector of claim 12 , wherein the first and second sections of electrically conductive plating form a differential signal pair.

14. The electrical connector of claim 13 , wherein the third section of electrically conductive plating is grounded.

15. The electrical connector of claim 14 , wherein
the housing and the first elongated section, the second elongated section and the third section comprise a first element of a plurality of like elements of the electrical connector; and
the electrical connector further comprises a support; and
the plurality of like elements are attached to the support.

16. A method of manufacturing the electrical connector of claim 8 , the method comprising:
depositing the first and second elongated sections of electrically conductive plating on surfaces of the insulative housing using vapor deposition.
