Abstract

An electrical connector (10) of a type adapted to connect signal and ground circuits between a mating connector (60) and a further circuit, board, or cable (50) includes a housing (12) having an interior cavity (20a) defined by side, top, and bottom walls (13, 14, 17, and 18) and a rear wall (16) with the surfaces of the housing being conductive to shield signal contacts (24, 26) therein extended through the rear wall (16) via insulating portions (22); the housing including longitudinal slots (30) containing grounding contacts (32) having spring driven edge portions (34) engaging the grounding and shielding surfaces of a mating connector (60) and post portions (38) extending out of the housing to interconnect to the grounding circuit of a further circuit, board, or cable. One embodiment features a plastic housing (12) with a metallic coating defining surface (M) and another embodiment includes a solid metallic housing (40) and a plastic insert (46).

Claims

1. An electrical connector for connecting signal and ground circuits between a matable connector and a circuit board or cable, comprising:

a housing having side, top, bottom and rear walls defining a connector-receiving cavity, the surfaces of the side, top, bottom and rear walls of the housing being electrically conductive, and said rear wall of said housing including an exposed dielectric section;

signal contacts secured in said dielectric section of said rear wall and having contact sections disposed within said connector-receiving cavity and termination sections extending exteriorly of said rear wall for electrical connection to signal conductors on the circuit board or to signal conductors of the cable; and

a ground contact secured in a slot extending along an interior surface of said connector-receiving cavity, said ground contact having a spring contact portion extending into the connector-receiving cavity for electrical connection with a shield member of the meltable connector when said matable connector is inserted into the connector-receiving cavity, said ground contact also having a termination portion for electrical connection with a ground conductor on the circuit board or with a conducive shield of the cable.

2. An electrical connector as claimed in claim 1, wherein said side, top, bottom and rear walls of said housing are made of dielectric material having an electrically conductive coating thereon constituting said electrically conductive surfaces.

3. An electrical connector as claimed in claim 2, wherein said dielectric section of said rear wall is part of said dielectric material of said rear wall without said electrically conductive coating on inner and outer surfaces thereof.

4. An electrical connector as claimed in claim 1 wherein said termination sections of said signal contacts comprise post sections.

5. An electrical connector as claimed in claim 1, wherein said termination portion of said ground contact comprises a post portion.

6. An electrical connector as claimed in claim 1, wherein said side, top, bottom and rear walls of said housing are made f metal.

7. An electrical connector as claimed in claim 6, wherein said dielectric section of said rear wall comprises a dielectric insert secured in an opening of said rear wall.

8. An electrical connector as claimed in claim 1, wherein said termination sections of said signal contacts have termination members for electrical connection to signal wires of the cable.

9. An electrical connector as claimed in claim 1, wherein said termination portion of said ground contact comprises another spring contact portion for electrical connection to a shield member of the cable.
