Abstract

Among other things, an apparatus and method for use with a high-voltage electrical connector are provided. The connector selectively connects a first electrical conductor to a second electrical conductor. The connector may comprise a body portion and a securing portion. The body portion and the securing portion may at least in part define an engaging aperture. A tensioning component may also be present to constrict and/or un-constrict the engaging aperture. The second electrical conductor may be received into or out of the engaging aperture in a direction lateral to the connector.

First claim

What is claimed is:

1. A high voltage electrical connector comprising:
a body portion;
a securing portion; and
a tensioning component,
at least one of the body portion or the securing portion adapted to connect to a first electrical conductor,
the body portion and the securing portion at least in part forming a surface defining an engaging aperture in an interior of the high voltage electrical connector, the surface comprising a planar portion and a non-planar portion, the planar portion adapted to engage a complimentary portion of a second electrical conductor to substantially mitigate rotation of the high voltage electrical connector relative to the second electrical conductor when the engaging aperture is at least partially un-constricted, and
the tensioning component adapted to at least constrict or un-constrict the engaging aperture.

2. The high voltage electrical connector of claim 1 , wherein the surface is further formed by the tensioning component.

3. The high voltage electrical connector of claim 1 , wherein the engaging aperture receives the second electrical conductor in a direction lateral to a longest extent of the body portion.

4. The high voltage electrical connector of claim 1 , wherein the engaging aperture is, at least when constricted, substantially complimentary in shape to a cross-sectional shape of the second electrical conductor.

5. The high voltage electrical connector of claim 1 , wherein at least some of the surface maintains an electrical connection and a physical connection between the high voltage electrical connector and the second electrical conductor during at least a partial rotation of the second electrical conductor relative to the high voltage electrical connector.

6. The high voltage electrical connector of claim 1 , wherein the planar portion is formed by the securing portion.

7. The high voltage electrical connector of claim 1 , wherein the non-planar portion is formed by the body portion.

8. The high voltage electrical connector of claim 1 , wherein the tensioning component comprises a threaded member extending between the body portion and the securing portion.

9. The high voltage electrical connector of claim 1 , wherein the securing portion is pivotally connected to the body portion.

10. The high voltage electrical connector of claim 1 , wherein the body portion is substantially hook shaped and the securing portion is configured to substantially close off an opening in the hook shape to form the engaging aperture.

11. The high voltage electrical connector of claim 1 , wherein the tensioning component is adapted to constrict the engaging aperture to lock the high voltage electrical connector onto the second electrical conductor.

12. A high voltage electrical connection assembly, the assembly comprising:
a high voltage electrical connector comprising:
a body portion;
a securing portion; and
a tensioning component,
at least one of the body portion or the securing portion adapted to connect to a first electrical conductor,
the body portion and the securing portion at least in part defining an engaging aperture in an interior of the high voltage electrical connector, and
the tensioning component adapted to at least one of constrict or un-constrict the engaging aperture, and

an elongated bar portion adapted to interface with the high voltage electrical connector,
the elongated bar portion having a first contoured surface and a second contoured surface adapted to interface with the engaging aperture, and
the elongated bar portion increasing in thickness toward an edge of the elongated bar portion.

13. The connection of claim 12 , wherein the first contoured surface is non-planar and the second contoured surface is planar.

14. The connection of claim 12 , wherein the second contoured surface is adapted to substantially mitigate rotation of the high voltage electrical connector relative to the elongated bar portion.

15. The connection of claim 12 , wherein the tensioning component is adapted to constrict the engaging aperture to mitigate rotation of the high voltage electrical connector relative to the elongated bar portion.

16. A method for selectively connecting a first electrical conductor to a second electrical conductor, comprising:
providing a high voltage electrical connector comprising:
a body portion and a securing portion, at least one of the body portion or the securing portion adapted to connect to the first electrical conductor, the body portion and the securing portion at least in part defining an engaging aperture, and
a tensioning portion configured to constrict and un-constrict the engaging aperture;

providing the second electrical conductor comprising:
at least one elongated bar portion for the high voltage electrical connector to engage, the elongated bar portion increasing in thickness toward at least one edge of the elongated bar portion; and

connecting the high voltage electrical connector to the elongated bar portion to connect the first electrical conductor to the second electrical conductor.

17. The method of claim 16 , the second electrical conductor operably coupled to a busbar for transmission of electricity.

18. The method of claim 16 , the second electrical conductor present on an earthing trolley.

19. A kit of parts, comprising:
a high voltage electrical connector comprising:
a body portion;
a securing portion; and
a tensioning component,
at least one of the body portion or the securing portion adapted to connect to a first electrical conductor,
the body portion and the securing portion at least in part defining an engaging aperture, and
the tensioning component adapted to constrict and un-constrict the engaging aperture; and

a second electrical conductor comprising:
at least one elongated bar portion for the high voltage electrical connector to engage, the at least one elongated bar portion having a planar surface and a non-planar surface to engage with the engaging aperture; and
a connecting portion to connect the elongated bar portion to least one of a busbar or an earthing point.

20. The high voltage electrical connector of claim 19 , wherein the engaging aperture is defined by a surface formed, at least in part, by the body portion and the securing portion, wherein the surface comprises a planar portion and a non-planar portion.
