Abstract

An electrical connector includes two pads having the same shape. Each pad has a connector body with a first groove, a second groove, and a hole. The hole extends through the connector body between the first groove and the second groove. A fastener extends through the hole of both of the two pads so that the two pads having the same shape are connected to one another and are pivotable around the fastener relative to one another with the two first grooves contacting a first conductor when the first conductor is in an installed position and the two second grooves contacting a second conductor when the second conductor is in an installed position. A spring is between a first end of the fastener and one of the two pads having the same shape so that the spring biases the two pads having the same shape towards each other.

Claims

1. An electrical connector comprising:

two pads having the same shape, each pad comprising a connector body having a first groove, a second groove, and a hole, the hole extending through the connector body between the first groove and the second groove;

a fastener extending through the hole of both of the two pads having the same shape so that the two pads having the same shape are connected to one another and are pivotable around the fastener relative to one another with the two first grooves contacting a first conductor when the first conductor is in an installed position and the two second grooves contacting a second conductor when the second conductor is in an installed position; and

a spring between a first end of the fastener and one of the two pads having the same shape so that the spring biases the two pads having the same shape towards each other,

wherein the connector body further includes a protruding tab on a first side and a side groove on a second side so that, when the two pads having the same shape are connected to one another, the protruding tabs are received in the side grooves, respectively.

16. The electrical connector of claim 1, wherein the two pads are bodies each having the same volume.

17. The electrical connector of claim 1, wherein the two pads having the same shape are cast bodies each having the same volume.

2. The electrical connector of claim 2, wherein the side groove is sized to limit movement of the protruding tab.

3. An electrical connector comprising:

two pads having the same shape, each pad comprising a connector body having a first groove, a second groove, and a hole, the hole extending through the connector body between the first groove and the second groove;

a fastener extending through the hole of both of the two pads having the same shape so that the two pads having the same shape are connected to one another and are pivotable around the fastener relative to one another with the two first grooves contacting a first conductor when the first conductor is in an installed position and the two second grooves contacting a second conductor when the second conductor is in an installed position; and

a spring between a first end of the fastener and one of the two pads having the same shape so that the spring biases the two pads having the same shape towards each other,

wherein the first groove has a first outer surface comprising a first flange and a first recess, wherein the first flange extends inward from a first side of the connector body a distance of half or less half an entire length of the first groove and the first recess extending inward from the first side of the connector body at least the distance of the first flange so that, when the two pads having the same shape are connected to one another, the first flanges are opposite and the first recesses, respectively.

4. The electrical connector of claim 3, wherein the second groove has a second outer surface comprising a second flange and a second recess, wherein the second flange extends inward from a second side of the connector body a distance of half or less half an entire length of the second groove and the second recess extends inward from the second side of the connector body at least the distance of the second flange so that, when the two pads having the same shape are connected to one another, the second flanges are opposite and the second recesses, respectively.

5. The electrical connector of claim 4, wherein the first flange is formed by a first receiving flange and a first protrusion, wherein the first receiving flange extends from the first groove at an angled direction away from the first groove and the protrusion is formed where the first receiving flange and the first groove meet and extends in a direction toward the first groove.

6. The electrical connector of claim 5, wherein the first receiving flange has a length of greater than 0.84 inches.

7. The electrical connector of claim 4, wherein the second flanges overlap the first recesses, respectively, when the second groove is free of the second conductor.

8. The electrical connector of claim 3, wherein the two pads having the same shape receive the first conductor having a diameter between 0.162 inches to 0.563 inches.

9. The electrical connector of claim 3, wherein the two pads having the same shape receive the second conductor having a diameter between 0.563 inches to 0.953 inches.

10. An electrical connector comprising:

two pads having the same shape, each pad comprising a connector body having a first groove, a second groove, and a hole, the hole extending through the connector body between the first groove and the second groove;

a fastener extending through the hole of both of the two pads having the same shape so that the two pads having the same shape are connected to one another and are pivotable around the fastener relative to one another with the two first grooves contacting a first conductor when the first conductor is in an installed position and the two second grooves contacting a second conductor when the second conductor is in an installed position; and

a spring between a first end of the fastener and one of the two pads having the same shape so that the spring biases the two pads having the same shape towards each other,

wherein the hole comprises an elongated portion and a recessed portion, and wherein the spring is received in the recessed portion of one of the two pads having the same shape and a second end of the fastener is received in the recessed portion of the other of the two pads having the same shape.

11. The electrical connector of claim 10, wherein the fastener has a fastener head and a fastener body, and wherein the recessed portion has a corresponding shape to the fastener head to prevent rotation of fastener in the opening.

12. The electrical connector of claim 10, wherein the recessed portion has a shape that corresponds to a shape of the spring to seat the spring.

13. The electrical connector of claim 10, wherein the fastener is a bolt having a head and a bolt body.

14. The electrical connector of claim 13, further comprising a Belleville washer secured on the bolt body with a nut.

15. The electrical connector of claim 13, wherein the bolt is connected to the two pads having the same shape by a shear-nut.
