Abstract

A plug connector for use with a receptacle. The plug connector and receptacle combination may prevent more than one use of the single use plug connector, thereby necessitating disposal of the plug connector and associated, disposable, specialized instrumentation to which the plug connector is connected. The plug connector may be keyed and otherwise identified to the receptacle by shape, tactile indicia and visual indicia so that it cannot be mistakenly used with a different receptacle, while providing proper orientation for rapid assembly. When designed for single use or limited multiple use, the insertion of the plug connector into the receptacle moves a jumper contact in the plug connector from a first position to a second position where it is captured. The receptacle and plug connector may include an interface for a light pipe and a light path that illuminates the plug connector to facilitate assembly and disassembly in areas in which light is limited, such as operating rooms, as well as communicating information to the user.

Claims

1. A plug connector, comprising:

a latching mechanism movable from a first engaged position to a second disengaged position,

the latching mechanism further including a latch release surface, and

a means for latching the mechanism to an opposed surface;

a plurality of metal contacts, each contact configured to accept a wire;

a housing to locate and align the plurality of metal contacts, the housing further including an exterior and an interior; and

a passageway extending from the exterior of the housing to the interior of the housing.

2. The plug connector of claim 1 wherein at least one of the latching mechanism and a portion of the housing comprises a light-transmitting material.

3. The plug connector of claim 2 wherein the light-transmitting material is selected from the group consisting of a translucent material and a transparent material.

4. The plug connector of claim 3 further including a conduit to transmit light to the housing interior.

5. The plug connector of claim 1 wherein the latching mechanism further includes a latching arm with a projection extending downward from the latching arm, the downward-extending projection comprising the means for latching the mechanism to an opposed surface.

6. The plug connector of claim 1 further including one of a key and keyway for aligning the plug connector to a mating receptacle.

7. The plug connector of claim 1 further including

a jumper contact movable from a first position to a second position when the latching mechanism is in the first engaged position;

and

a means for capturing the jumper contact in the second position.

8. The plug connector of claim 7 wherein the means for capturing the jumper contact in the second position includes a surface having dimensional tolerances that interfere with the jumper contact, thereby capturing it in the second position.

9. The plug connector of claim 7 wherein the means for capturing the jumper contact is a depression in the housing sized to accept the jumper contact when the jumper contact is moved to a second position.

10. The plug connector of claim 7wherein the means for capturing the jumper contact includes a jumper contact having a dimple and a raised block having a biased nipple that engages the dimple when the jumper contact is moved to the second position, thereby capturing the jumper contact in the second position.

11. A receptacle, comprising:

a plurality of metal spring contacts, each contact having a first end and a second end, the first end configured to accept a wire and the second end configured to mate with a corresponding metal contact of a plug connector, each contact having a first fixed length;

a housing to locate and align the plurality of spring contacts with the fixed metal contact, the housing having a first end and a second end, the second end of the spring contacts and the fixed metal contact extending away from the second end of the housing; and

means for locking a mating plug connector.

12. The receptacle of claim 11 further including a plurality of fixed metal contacts having a first end and a second end, the first end configured to accept a wire, the fixed metal contact having a second length;

13. The receptacle of claim 11 further including further including a key and a matching keyway for aligning the receptacle to a mating plug connector.

14. The receptacle of claim 11 further including a means for transmitting light.

15. The receptacle of claim 11 wherein the means for transmitting light includes an opening for a light pipe to transmit light through the receptacle housing.

16. The receptacle of claim 11 wherein the means for transmitting light includes a light.

17. A plug connector/receptacle assembly, comprising:

a plug connector, including

a latching mechanism movable from a first engaged position to a second disengaged position, the latching mechanism further including a latch release surface, and a means for latching the mechanism to an opposed surface;

a plurality of metal contacts, each contact having a first end and a second end, the first end of each contact configured to accept a wire;

a housing having a predetermined geometric configuration to locate and align the plurality of metal contacts, the housing further including an exterior and an interior, the exterior of the housing further including at least one of visual and tactile indicia to facilitate proper mating of the plug connector, and

a passageway extending from the exterior of the housing to the interior of the housing; and

a receptacle, the receptacle having a predetermined geometric configuration that mates with the geometric configuration of the plug connector so that the plug connector is capable of unique mating to the receptacle and further including

a plurality of metal spring probes, each probe having a first end and a second end, the first end of each spring contact configured to accept a wire and the second ends of the plurality of metal spring contacts configured to mate with the second end of the plurality of metal contacts of the plug connector, each of the metal spring contacts having a second length,

a housing for locating and positioning the plurality of metal spring contacts, the housing having a first end and a second end, the second end of the spring contacts extending away from the second end of the housing, and

a surface that includes means for locking the mating plug connector, the means for locking mating with the means for latching of the plug connector.

18. The plug connector/receptacle assembly of claim 17 further including a jumper contact movable from a first position to a second position when the latching mechanism is in the first engaged position, and fixed metal contacts to move the jumper contact from the first position to the second position, and a means for capturing the jumper contact in the second position.

19. The plug connector/receptacle assembly of claim 17 wherein at least one of the plug connector housing and the plug connector latching mechanism comprises a light transmitting material selected from the group consisting of a transparent material and a translucent material, and forms a portion of the light path that illuminates the plug connector with light received from the light source.

20. The plug connector/receptacle assembly of claim 19 wherein a light pipe in the light path transmits light from an external source through the receptacle to the plug connector.

21. The plug connector/receptacle assembly of claim 17 wherein a light source is positioned within the receptacle.

22. The plug connector/receptacle assembly of claim 17 wherein the receptacle further includes a light pipe and the plug connector includes a light path.

23. The plug connector/receptacle assembly of claim 17 further including a key/keyway for locating the plug connector to the receptacle wherein the plug connector includes one of the key and keyway, and the receptacle includes the other of the key and keyway.

24. The plug connector/receptacle assembly of claim 17 further including a plurality of fixed metal contacts having a first end and a second end, the first end configured to accept a wire, the fixed metal contacts having a second length configured to mate with the jumper contact in its first position, wherein the fixed metal contacts and the jumper contact mate at a different time than the plurality of metal spring contacts mate with the plurality of metal contacts of the plug connector.
