Abstract

An electrical connector includes a dielectric housing, with a plurality of conductive terminals mounted in the housing. At least one of the terminals is a ground terminal. A metal shield is mounted on the housing. An intermediate conductive terminal is mounted on the housing and includes one end engaging the metal shield and an opposite end engaging the ground terminal.

Claims

1. An electrical connector, comprising:

a dielectric housing having a connector mating face and a circuit board receiving face;

a plurality of conductive terminals mounted in the housing, each terminal including a contact end generally at the connector mating face of the housing and a board-engaging end generally at the circuit board receiving face of the housing and at least one of the terminals being a ground terminal;

a metal shield mounted on the housing about at least the connector mating face thereof; and

an intermediate conductive terminal mounted on the housing and including one end engaging the metal shield and an opposite end engaging the ground terminal.

2. The electrical connector of claim 1 wherein said one end of the intermediate terminal abuts against an inner surface of the metal shield and said opposite end of the intermediate terminal abuts the ground terminal.

3. The electrical connector of claim 2 wherein said intermediate terminal is stamped and formed from conductive sheet metal material with its opposite ends formed for surface abutting the metal shield and the ground terminal.

4. The electrical connector of claim 1 wherein said intermediate terminal includes a resilient portion between its opposite ends to provide a contact pressure with the metal shield and the ground terminal.

5. The electrical connector of claim 4 wherein said resilient portion is generally S-shaped.

6. The electrical connector of claim 5 wherein said intermediate terminal is stamped and formed of conductive sheet metal material with said S-shaped resilient portion being generally planar and with the opposite ends of the intermediate terminal being formed to extend out of the plane of the S-shaped resilient portion.

7. The electrical connector of claim 1 wherein said intermediate terminal is disposed for free movement within a groove in the housing.

8. The electrical connector of claim 7 wherein said intermediate terminal includes a resilient portion between its opposite ends to provide a contact pressure with the metal shield and the ground terminal, said resilient portion being located substantially in said groove, and the opposite ends of the intermediate terminal being exposed at opposite ends of the groove for engaging the metal shield and the ground terminal.

9. An electrical connector, comprising:

a dielectric housing having a connector mating face with a connector receptacle for receiving a complementary mating connector having mating terminals, and a circuit board receiving face having a board receptacle for receiving a printed circuit board having conductors thereon;

a plurality of conductive terminals mounted in the housing, each terminal including a contact end exposed in said connector receptacle and a board-engaging end exposed in said board receptacle, and at least one of the terminals being a ground terminal with its board-engaging end engaging a ground circuit of the printed circuit board;

a metal shield mounted on the housing about at least the connector mating face thereof; and

an intermediate conductive terminal disposed for free movement within a groove in the housing, the intermediate terminal including one end abutting an inner surface of the metal shield, an opposite end abutting the ground terminal and a resilient portion between said opposite ends to provide a contact pressure with the metal shield and the ground terminal, the resilient portion being located substantially within said groove in the housing, and the opposite ends of the intermediate terminal being exposed at opposite ends of the groove for engaging the metal shield and the ground terminal.

10. The electrical connector of claim 9 wherein said resilient portion of the intermediate terminal is generally S-shaped.

11. The electrical connector of claim 10 wherein said intermediate terminal is stamped and formed of conductive sheet metal material with said S-shaped resilient portion being generally planar and with the opposite ends of the intermediate terminal being formed to extend out of the plane of the S-shaped resilient portion.

12. An electrical connector, comprising:

a dielectric housing;

a plurality of conductive terminals mounted in the housing, at least one of the terminals being a ground terminal;

a metal shield mounted on the housing; and

an intermediate conductive terminal mounted on the housing and including one end engaging the metal shield, an opposite end engaging the ground terminal, and a resilient portion between the ends to provide a contact pressure with the metal shield and the ground terminal, the resilient portion being generally S-shaped.

13. The electrical connector of claim 12 wherein said one end of the intermediate terminal abuts against an inner surface of the metal shield and said opposite end of the intermediate terminal abuts the ground terminal.

14. The electrical connector of claim 13 wherein said intermediate terminal is stamped and formed from conductive sheet metal material with its opposite ends formed for surface abutting the metal shield and the ground terminal.

15. The electrical connector of claim 12 wherein said intermediate terminal stamped and formed of conductive sheet metal material with said S-shaped resilient portion being generally planar and with the opposite ends of the intermediate terminal being formed to extend out of the plane of the S-shaped resilient portion.

16. The electrical connector of claim 12 wherein said intermediate terminal is disposed for free movement within a groove in the housing.

17. The electrical connector of claim 16 wherein said intermediate terminal includes a resilient portion between its opposite ends to provide a contact pressure with the metal shield and the ground terminal, said resilient portion being located substantially in said groove, and the opposite ends of the intermediate terminal being exposed at opposite ends of the groove for engaging the metal shield and the ground terminal.

18. An electrical connector, comprising:

a dielectric housing;

a plurality of conductive terminals mounted in the housing, at least one of the terminals being a ground terminal;

a metal shield mounted on the housing; and

an intermediate conductive terminal mounted on the housing and including a resilient portion between two ends of the terminal, one end engaging the metal shield and an opposite end engaging the ground terminal, the resilient portion providing a contact pressure between the metal shield and the ground terminal.
