Abstract

An electrical connector including first and second connector parts configured for mating together, and with one of the connector parts having a sensory feedback member that moves between an extended position and a retracted position as a result of magnetic interaction with an actuation element in the other connector part during mating of the connector parts. The movement of the sensory feedback member causes a sensory feedback indication, such as an audible sound or a tactile vibration.

Claims

1. An electrical connector comprising:

a first connector part and a second connector part that are configured for mating engagement with one another, each connector part having at least one electrical contact;

a sensory feedback member mounted at the second connector part and movable between a retracted position and an extended position relative to the second connector part, wherein the sensory feedback member comprises a magnetically permeable material; and

an actuation element at the first connector part and comprising a magnetically permeable material, wherein the actuation element and the sensory feedback member are magnetically interactive with one another;

wherein the actuation element is configured to force the sensory feedback member, by magnetic interaction, to move between the retracted position and the extended position upon mating engagement of the first and second connector parts.

2. The electrical connector of claim 1, wherein the sensory feedback member is configured to generate at least one of an audible sound and a tactile sensation, upon moving between the retracted position and the extended position.

3. The electrical connector of claim 1, wherein at least one of the actuation element and the sensory feedback member comprises a permanent magnet.

4. The electrical connector of claim 1, wherein the actuation element and the sensory feedback member each comprises a permanent magnet.

5. The electrical connector of claim 1, wherein the sensory feedback member is generally cylindrical and the second connector part comprises a generally cylindrical bore in which the sensory feedback member is slidably supported.

6. The electrical connector of claim 1, wherein the second connector part comprises a hollow chamber formed behind the actuation element for selectively receiving a rear portion of the actuation element in the retracted position.

7. The electrical connector of claim 1, further comprising a biasing member at a rear end of the hollow chamber in the second connector part, wherein the biasing member is configured to cause the sensory feedback member to move to the retracted position when the first and second connector parts are not mated.

8. The electrical connector of claim 7, wherein the biasing member comprises a permanent magnet.

9. The electrical connector of claim 8, wherein the actuation element comprises a permanent magnet, the actuation element has a greater magnetic field strength than a magnetic field strength of the biasing member, and the magnetic field strength of the actuation element is sufficient to overcome the magnetic field strength of the biasing member to move the sensory feedback member to the extended position upon mating of the connector parts.

10. The electrical connector of claim 1, wherein a forward surface of the sensory feedback member is substantially flush with a forward surface of the second connector part when the sensory feedback member is in the retracted position.

11. An electrical connector comprising:

first and second connector parts configured for mating engagement with one another, each connector part having an electrical contact configured for mutual engagement;

a magnetically permeable sensory feedback member mounted at the second connector part and movable between a retracted position and an extended position relative to the second connector part; and

a magnetically permeable actuation element at the first connector part;

wherein at least one of the actuation element and the sensory feedback member comprises a permanent magnet, and the actuation element and the sensory feedback member are magnetically interactive;

wherein the actuation element is configured to force the sensory feedback member, by magnetic interaction, to move between the retracted position and the extended position upon at least initial mating engagement of the first and second connector parts; and

wherein the sensory feedback member is configured to generate an audible sound or a tactile sensation, upon moving between the retracted position and the extended position.

12. The electrical connector of claim 11, wherein the actuation element is configured to force the sensory feedback member to move between the retracted position and the extended position only after the electrical contacts of the first and second connector parts establish electrical continuity during coupling of the first and second connector parts.

13. The electrical connector of claim 11, wherein the actuation element and the sensory feedback member each comprises a permanent magnet.

14. The electrical connector of claim 11, wherein the actuation element is disposed in a central region of the first connector part and the sensory feedback member is disposed in a central region of the second connector part, wherein the first connector part comprises a pair of the electrical contacts arranged on opposites sides of the actuation element and the second connector part comprises a pair of the electrical contacts arranged on opposites sides of the sensory feedback member.

15. The electrical connector of claim 11, wherein the sensory feedback member is generally cylindrical and the second connector part comprises a generally cylindrical bore in which the sensory feedback member is slidably supported.

16. The electrical connector of claim 11, wherein the second connector part comprises a hollow chamber formed behind the actuation element for selectively receiving a rear portion of the actuation element in the retracted position.

17. The electrical connector of claim 16, further comprising a biasing member at a rear end of the hollow chamber in the second connector part, wherein the biasing member is configured to cause the sensory feedback member to move to the retracted position when the first and second connector parts are not mated.

18. The electrical connector of claim 17, wherein the biasing member comprises a permanent magnet.

19. The electrical connector of claim 18, wherein the actuation element comprises a permanent magnet, the actuation element has a greater magnetic field strength than a magnetic field strength of the biasing member, and the magnetic field strength of the actuation element is sufficient to overcome the magnetic field strength of the biasing member to move the sensory feedback member to the extended position upon mating of the connector parts.

20. The electrical connector of claim 11, wherein a forward surface of the sensory feedback member is substantially flush with a forward surface of the second connector part when the sensory feedback member is in the retracted position.
