Abstract
A cable coupler includes a body having a first end, a second end, and first and second passageways sized and shaped to receive a cable, with each passageway including a tapered portion. A wedge assembly is disposed in each tapered portion to secure a cable to the body. A clip assembly is attached to the body adjacent the tapered portion of each of the passageways and is shiftable between a closed position in which the clip assembly is positioned to prevent an adjacent one of the wedge assemblies from exiting the corresponding passageway and an open position in which the adjacent wedge assembly is insertable into the tapered portion of the corresponding passageway.
Claims19
A cable coupler comprising:
- a body having a first end, a second end, and first and second passageways extending between the first end and the second end, each passageway sized and shaped to receive a cable, each passageway including a tapered portion;
- the tapered portion of the first passageway disposed adjacent the first end of the body and the tapered portion of the second passageway disposed adjacent the second end of the body;
- a first wedge assembly disposed in the tapered portion of the first passageway and a second wedge assembly disposed in the tapered portion of the second passageway, each of the first and second wedge assemblies comprising at least two wedge pieces and arranged to secure a cable to the body;
- and
- a first retainer disposed adjacent the first end of the body and coupled to a pair of apertures, the first retainer arranged for placement in a closed position in which the first retainer obstructs a portion of the first passageway thereby preventing the corresponding wedge assembly from exiting the first passageway;
- and
- a second retainer disposed adjacent the second end of the body and coupled to a pair of apertures, the second retainer arranged for placement in a closed position in which the second retainer obstructs a portion of the first passageway thereby preventing the corresponding wedge assembly from exiting the second passageway.

A cable coupler comprising:
- a body having a first end, a second end, and first and second passageways extending between the first end and the second end, each passageway sized and shaped to receive a cable, each passageway including a tapered portion, the tapered portion of the first passageway and the tapered portion of the second passageway disposed at opposite ends of the body;
- a first wedge assembly disposed in the tapered portion of the first passageway and a second wedge assembly disposed in the tapered portion of the second passageway, the first and second wedge assemblies arranged to secure a cable to the body from opposite directions;
- a first retainer arranged for placement adjacent the first end of the body, the first retainer operatively coupled to the body and arranged for placement in a position to obstruct a portion of the first passageway thereby preventing the first wedge assembly from exiting the first passageway;
- and
- a second retainer arranged for placement adjacent the second end of the body, the second retainer operatively coupled to the body and arranged for placement in a position to obstruct a portion of the second passageway preventing the second wedge assembly from exiting the second passageway.

A cable coupler comprising:
- a body having a first end, a second end, and first and second passageways extending between the first end and the second end, each passageway sized and shaped to receive a cable, each passageway including a tapered portion, the tapered portion of the first passageway and the tapered portion of the second passageway disposed at opposite ends of the body;
- a first wedge assembly disposed in the tapered portion of the first passageway and a second wedge assembly disposed in the tapered portion of the second passageway, the first and second wedge assemblies arranged to secure a cable to the body from opposite directions;
- a retainer arranged for placement adjacent the first end of the body, the retainer operatively coupled to a pair of cooperating recesses in the body;
- wherein the retainer includes a portion sized and positioned to obstruct a portion of the first passageway thereby preventing the first wedge assembly from exiting the first passageway;
- and
- wherein the portion of the retainer is adapted for movement to a position in which the portion of the first passageway is not obstructed.
