Abstract

The present invention discloses a device for electrically connecting an external device into a circuit running from an apparatus control switch, to an apparatus, thus allowing the interception and redirection of the control signal to the external device. It concerns a simple, completely enclosed, error-proof connector which allows for simultaneous operation of the apparatus and the external device.

Claims

1. An intermediate connector for electrically coupling an external device between a first connector coupled to one electrical device, the first connector having prongs extending from the connector, and a second connector coupled to another electrical device, the second connector having receptacles extending into the second connector, wherein the second connector is capable of electrically connecting to the first connector by way of mating the prongs in the receptacles, the intermediate connector comprising:

a plurality of prongs, extending from one end of the intermediate connector and capable of electrically connecting with the receptacles of the second connector;

a plurality of receptacles extending into an opposite end of the intermediate connector and capable of electrically connecting with the prongs of the first connector;

a first conductor having a length and capable of being electrically coupled to the external device, the first conductor being electrically coupled at a first end of the first conductor to at least one of the plurality of prongs at a first coupling point;

a second conductor being electrically coupled at a first end of the second conductor to at least one of the plurality of receptacles at a second coupling point;

a connector body enclosing and electrically insulating the first coupling point and the second coupling point from external contact, except by one of the plurality of prongs, one of the plurality of receptacles, a distal end of the first conductor or a distal end of the second conductor, wherein the distal end of the first conductor extends from the connector body and is capable of being electrically coupled to the external device; and

wherein the plurality of prongs, the plurality of receptacles, the first conductor, and the second conductor are disposed and electrically coupled such that, when the intermediate connector is inserted between the first connector and the second connector, an electric current from at least one of the prongs of the first connector is diverted to the first conductor prior to being redirected to the receptacle of the second connector to which it would have otherwise been directed if the prongs of the first connector remained directly connected to the receptacles of the second connector without insertion of the intermediate connector between the first connector and the second connector.

2. The intermediate connector of claim 1, wherein at least one of the plurality of receptacles is directly electrically connected to at least one of the plurality of prongs positioned opposite of the at least one of the plurality of receptacles.

3. The intermediate connector of claim 2, wherein

each of the plurality of receptacles are disposed directly opposite of a respective one of the plurality of male prongs and directly electrically connected with the respective one of the plurality of male prongs disposed directly opposite thereof;

each of the plurality of receptacles has a first shape or a second shape, different from the first shape;

each of the plurality of prongs has a corresponding first shape or a second shape, different from the first shape, such that a prong having the first shape is capable of mating with a receptacle having the first shape, but not with a receptacle having the second shape; and

at least one of the plurality of receptacles has the first shape and the respective one of the plurality of male prongs directly connected with the at least one of the plurality of receptacles having the first shape has the second shape.

4. The intermediate connector of claim 3, wherein there are four receptacles and four prongs oriented such that, when the intermediate connector is inserted between the first connector and the second connector, thereafter the second connector must be rotated 90 degrees from its normal orientation with respect to the first connector in order for the receptacles of the second connector to mate with the prongs of the intermediate connector.

5. The intermediate connector of claim 4, wherein the first end of the first conductor is electrically coupled to a first prong and a first receptacle, the first end of the second conductor is electrically coupled to a second prong and a second receptacle and the distal end of the second conductor is electrically coupled to a fourth receptacle and a fourth prong.

6. The intermediate connector of claim 5, wherein the second conductor is entirely enclosed with the connector body.

7. The intermediate connector of claim 6, further comprising a third conductor having a first end and a distal end, wherein the third conductor is electrically coupled at the first end of the third conductor to a third prong and a third receptacle, and the distal end of the third conductor extends from the connector body and is capable of being electrically coupled to the external device.

8. The intermediate connector of claim 7, further comprising a fourth conductor having a first end and a distal end, wherein the first end of the fourth conductor is electrically coupled to the fourth prong, and the fourth receptacle, and the distal end of the fourth conductor extends from the connector body and is capable of being electrically coupled to the external device.

9. The intermediate connector of claim 1, wherein at least one of the plurality of receptacles is not directly connected with any of the plurality of prongs.

10. The intermediate connector of claim 9, wherein the distal end of the second conductor extends from the connector body and is capable of electrically coupling with the external device.

11. The intermediate connector of claim 10, wherein the first conductor is coupled to a first prong, the second conductor is coupled to a first receptacle disposed opposite of the first prong, and the first prong is not electrically coupled to the first receptacle when the first conductor is not electrically coupled to the second conductor.

12. The intermediate connector of claim 11, wherein the plurality of prongs is three prongs and the plurality of receptacles is three receptacles.

13. The intermediate connector of claim 12, wherein a second receptacle is directly electrically connected to a second prong, disposed opposite of the second receptacle, within the connector body.

14. The intermediate connector of claim 13, further comprising a third conductor having a first end and a distal end, wherein the second receptacle is electrically coupled to the first end of the third conductor at a third coupling point and the distal end of the third conductor extends from the connector body and is capable of being electrically coupled to the external device.

15. The intermediate connector of claim 14, wherein the third receptacle and third prong are not electrically coupled to any other receptacles or prong and are not electrically coupled to any conductor within the connector body.

16. The intermediate connector of claim 15, wherein the connector body is cylindrical.

17. The intermediate connector of claim 16, wherein the distal ends of each of the first conductor, the second conductor and the third conductor are stripped bare and the remainder of each of the first conductor, the second conductor and the third conductor are electrically insulated from each other and from external contact.
