Abstract
A coupling for one end of screened conduit has two brass cones which are nested together and through which extend screened cables. Several apertures are formed around the inner cone which open into the space between the two cones. The braiding of each cable is stripped to one side and threaded through individual apertures so that it extends into the space between the cones. A threaded clamping nut urges the two cones together so that the braiding is clamped between them and good electrical connection is made.
Claims9
In a coupling for braided cable including an inner member of electrically-conductive material having a tapering external surface, and an outer member of electrically-conductive material having a tapering internal surface, so that when the tapering surfaces on the inner and outer members are drawn towards one another braiding from the cable can be clamped in the space between the tapering surfaces on the inner and outer members, the improvement wherein one of said members has at least one aperture therethrough through which braiding of the cable can extend into the space between the two tapering surfaces.
A coupling for a plurality of braided cables comprising:
- an outer conical member of metal;
- an inner conical member of metal nested within the outer member to form a space between the outer surface of the inner member and the inner surface of the outer member;
- a plurality of apertures through the inner member which open into the space between the members such that braiding from each cable can be led through a respective one of the apertures into the space;
- and a clamping member arranged to draw the inner and outer members together to clamp the braiding between the inner and outer members.
A coupling for making electrical connection of an electrical conduit to braiding on a plurality of braided cables extending through the conduit comprising:
- a first end secured to the electrical conduit;
- a second end opposite the first including a strain relief clamp clamped onto the cables;
- an outer conical member of metal;
- an inner conical member of metal nested within the outer member to form a space between the outer surface of the inner member and the inner surface of the outer member;
- a plurality of apertures through the inner member which open into the space between the members and through which braiding from respective cables extend into the space;
- and a clamping member that draws the inner and outer member together to clamp the braiding between the inner and outer members.
