Abstract

An electrical connector having a plug assembly and a socket assembly is described. The plug assembly includes a plug body and an outer barrel with an inner conductive receptacle electrically coupled to a first conductor in the plug body. The socket assembly includes a socket body movably held within an outer housing by a positioning ring, the socket body having a socket barrel with a second conductor fixed therein to be received in the conductive receptacle of the plug assembly.

Claims (26)

1. An electrical connector, comprising:

a plug assembly having a plug body and an outer barrel with an inner conductive receptacle electrically coupled to a first conductor in the plug body;

a socket assembly having a socket body movably held within an outer housing by a positioning ring, the socket body having a socket barrel with a second conductor fixed therein to be received in the inner conductive receptacle of the plug assembly, the second conductor electrically coupled to a third conductor through a flexible conductor, wherein the plug assembly and the socket assembly comprise alignment features to align the inner conductive receptacle and the second conductor during coupling of the socket assembly and the plug assembly; and

a locking feature to secure the socket assembly and the plug assembly in a coupled position, the locking feature comprising a ratcheting mechanism to allow for a range of coupled positions, the ratcheting mechanism including a pair of tangs extending from the socket body, each tang having a hook that engages sloped teeth of the plug body.

2. The electrical connector of claim 1 , wherein the alignment features comprise a projecting conical surface on the plug body and a recessed conical surface on the socket body.

3. The electrical connector of claim 1 , wherein the positioning ring comprises elastomeric foam.

4. The electrical connector of claim 1 , wherein the positioning ring comprises a number of metal or thermoplastic spring elements.

5. The electrical connector of claim 1 , wherein a positive contact is housed in the inner conductive receptacle to facilitate electrical coupling between the inner conductive receptacle and the second conductor.

6. The electrical connector of claim 5 , wherein the second conductor further comprises an insulating tip guard.

7. The electrical connector of claim 1 , wherein at least one of the plug assembly and the socket assembly is coupled with a photovoltaic module.

8. The electrical connector of claim 1 , further comprising:

weep holes disposed in the socket assembly for water vapor transfer away from the second conductor.

9. The electrical conductor of claim 1 , wherein an elastomeric tip is disposed at the end of the outer barrel of the plug assembly, and wherein the elastomeric tip of the plug assembly is provided to effect a compression fit in the socket barrel.

10. The electrical conductor of claim 1 , the flexible conductor extending from the socket body through the positioning ring.

11. An electrical connector, comprising:

a plug assembly having a plug body and an outer barrel with an inner conductive receptacle electrically coupled to a first conductor in the plug body, wherein a positive contact is housed in the inner conductive receptacle and is operable at a plurality of insertions depths; and

a socket assembly having a socket body movably held within an outer housing by a positioning ring, the socket body having a socket barrel with a second conductor fixed therein to be received in the inner conductive receptacle of the plug assembly, wherein the plug assembly and the socket assembly include alignment features to align the inner conductive receptacle and the second conductor during coupling of the socket assembly and the plug assembly, and wherein the plug assembly and the socket assembly comprise a locking feature to secure the socket assembly and the plug assembly in a coupled position, the locking feature comprising a ratcheting mechanism to allow for a range of coupled positions, the ratcheting mechanism including a pair of tangs extending from the socket body, each tang having a hook that engages sloped teeth of the plug body.

12. The electrical connector of claim 11 , wherein the alignment features comprise a projecting conical surface on the plug body and a recessed conical surface on the socket body.

13. The electrical connector of claim 11 , wherein the positioning ring comprises elastomeric foam.

14. The electrical connector of claim 11 , wherein the positioning ring comprises a number of metal or thermoplastic spring elements.

15. The electrical connector of claim 11 , wherein the fixed conductor further comprises an insulating tip guard.

16. The electrical connector of claim 11 , wherein at least one of the plug assembly and the socket assembly is coupled with a photovoltaic module.

17. The electrical connector of claim 11 , further comprising:

weep holes disposed in the socket assembly for water vapor transfer away from the second conductor.

18. The electrical connector of claim 11 , wherein an elastomeric tip is disposed at the end of the outer barrel, and wherein the elastomeric tip of the plug assembly is provided to effect a compression fit in the socket barrel.

19. The electrical connector of claim 11 , wherein the second conductor is electrically coupled to a third conductor through a flexible conductor extending from the socket body through the positioning ring.
