Abstract

The subject disclosure is directed to female connectors which can be employed in a quick connect/disconnect system used in medical devices to provide a non-permanent electrical and mechanical engagement with a male connector. The female connectors include, inter alia, a connector body that has an outer periphery and an aperture extending therethrough. The connector body has a flexible, non-conductive portion and a conductive portion which is at least partially exposed in the aperture and on the outer periphery of the connector body. The connector body is constructed such that when a male connector is inserted into the aperture of the connector body, the flexible, non-conductive part and the conductive part of the connecter body cooperate to allow for expansion of the aperture, creating contact pressure between the conductive part of the connector body and the male connector.

Claims

1. A female connector for positioning in an insulated adapter housing to receive a male connector, the female connector comprising:

a connector body having an outer periphery and defining a through aperture having an inner periphery, the connector body including a flexible, non-conductive portion and a conductive portion having diametrically opposed conductive segments, each conductive segment at least partially extending continuously around the outer periphery of the body and into the inner periphery of the aperture, wherein the connector body is constructed such that when the male connector is inserted through the aperture of the connector body, the flexible, non-conductive portion of the connector body and the conductive portion of the connecter body cooperate to allow for radially outward expansion of the aperture, thereby creating radially inwardly directed contact pressure between the conductive portion of the connector body that partially defines the inner periphery of the aperture and an outer periphery of the male connector inserted therethrough.

2. A female connector as recited in claim 1, wherein the connector body is a cuboid.

3. A female connector as recited in claim 1, wherein the aperture has a circular cross-section when viewed in a plane extending perpendicularly through its central axis.

4. A female connector as recited in claim 1, wherein the conductive portion of the connector body is more rigid than the non-conductive portion of the connector body.

5. A female connector as recited in claim 1, wherein the conductive portion of the connector body includes two or more conductive segments.

6. A female connector as recited in claim 5, wherein conductive portion of the connector body includes two conductive segments which are positioned on diametrically opposing sides of the aperture to partially define the inner periphery of the aperture.

7. A female connector as recited in claim 1, wherein at least a portion of the aperture is defined by the flexible, non-conductive portion of the connector body.

8. A female connector as recited in claim 1, wherein the conductive portion of the connector body is made from either titanium, 316L stainless steel or MP35N, or combinations thereof.

9. A female connector as recited in claim 1, wherein the conductive portion of the connector body is made from a nonmagnetic, nickel-cobalt-chromium-molybdenum alloy.

10. A female connector as recited in claim 1, wherein the non-conductive portion of the connector body is made from silicon.

11. A female connector as recited in claim 1, wherein the connector body is made using an over-molded process.

12. A female connector as recited in claim 1, wherein the connector body is made using an injection molding process.

13. A female connector for insertion into an insulated adapter housing to receive a male connector, the female connector comprising:

a connector body having an outer periphery and defining a circular through aperture with an annular inner periphery having an inner diameter, the connector body including a flexible, non-conductive portion and a conductive portion having diametrically opposed conductive segments, each conductive segment at least partially extending continuously around the outer periphery of the body and into the inner periphery of the aperture, wherein the connector body is constructed such that when the outer diameter of the male connector is larger than the inner diameter of the aperture, the flexible, non-conductive portion of the connector body and the conductive portion of the connecter body cooperate to allow for radially outward expansion of the aperture and receipt of the male connector, and create radially inwardly directed contact pressure between the conductive portion of the connector body that partially defines the inner periphery of the aperture and the outer diameter of the male connector.

14. A female connector as recited in claim 13, wherein the connector body is a cuboid.

15. A female connector as recited in claim 13, wherein the conductive portion of the connector body is more rigid than the non-conductive portion of the connector body.

16. A female connector as recited in claim 13, wherein the conductive portion of the connector body includes two or more conductive segments.

17. A female connector as recited in claim 16, wherein conductive portion of the connector body includes two conductive segments which are positioned on diametrically opposing sides of the aperture to partially define the inner periphery of the aperture.

18. A female connector as recited in claim 13, wherein at least a portion of the aperture is defined by the flexible, non-conductive portion of the connector body.

19. A female connector as recited in claim 13, wherein the conductive portion of the connector body is made from either titanium, 316L stainless steel or MP35N, or combinations thereof.

20. A female connector as recited in claim 13, wherein the conductive portion of the connector body is made from a nonmagnetic, nickel-cobalt-chromium-molybdenum alloy.

21. A female connector as recited in claim 13, wherein the non-conductive portion of the connector body is made from silicon.

22. A female connector as recited in claim 13, wherein the connector body is made using an over-molded process.

23. A female connector as recited in claim 13, wherein the connector body is made using an injection molding process.
