Electrical connector assembly with moveable inner insulator and terminal

1. An electrical connector assembly, comprising:

a central electrical terminal connected to a cable terminal attached to an end of a central conductor of an electrical cable configured to mate with a corresponding mating central electrical terminal, wherein the central electrical terminal comprises a helical coil spring in compressive contact with the cable terminal;

an insulative housing defining a cavity in which the central electrical terminal is affixed; and

a shield terminal in which the insulative housing, central electrical terminal, and coil spring are disposed, wherein the insulative housing is configured to move longitudinally within the shield terminal and wherein the coil spring exerts a longitudinal force on the central electrical terminal and the insulative housing to maintain mechanical contact between the insulative housing and a corresponding insulative housing in which the corresponding mating central electrical terminal is disposed.

2. The electrical connector assembly according to claim 1 , wherein a first portion of the coil spring is in radially compressive contact with the central electrical terminal.

3. The electrical connector assembly according to claim 2 , wherein coils of a second portion of the coil spring are spaced apart from one another when the coil spring is in a relaxed condition.

4. The electrical connector assembly according to claim 3 , wherein coils of a third portion of the coil spring are touching one another when the coil spring is in a relaxed condition.

5. The electrical connector assembly according to claim 3 , wherein coils of a third portion of the coil spring in which the central electrical terminal is not disposed are touching one another when the coil spring is in a relaxed condition.

6. The electrical connector assembly according to claim 1 , wherein a portion of the central electrical terminal is received within the coil spring and is rod-shaped.

7. The electrical connector assembly according to claim 1 , wherein the central conductor of the electrical cable is arranged perpendicularly to the central electrical terminal.

8. The electrical connector assembly according to claim 1 , wherein the insulative housing is movable between a rearward stop and a forward stop.

9. The electrical connector assembly according to claim 8 , wherein the forward stop is provided by an indentation in the shield terminal.

10. The electrical connector assembly according to claim 8 , wherein the rearward stop is provided by the coil spring when in a fully compressed condition.

11. The electrical connector assembly according to claim 8 , wherein the electrical contact attached to the central conductor of the electrical cable defines a spherical sector shaped electrical contact.

12. The electrical connector assembly according to claim 11 , wherein the electrical contact is an electrically conductive sphere attached to an end of the central conductor of the electrical cable.

13. The electrical connector assembly according to claim 11 , wherein the insulative housing is a first insulative housing defining a first cavity.

14. The electrical connector assembly according to claim 13 , wherein the first insulative housing is disposed within a first section of the shield terminal.

15. The electrical connector assembly according to claim 14 , wherein the assembly further comprises a second insulative housing defining a second cavity in which the electrical contact and an end of the central conductor of the electrical cable are disposed.

16. The electrical connector assembly according to claim 15 , wherein the second insulative housing is disposed in a second section of the shield terminal attached to the first section of the shield terminal.

17. The electrical connector assembly according to claim 15 , wherein a forward edge of the second insulative housing provides the rearward stop.
