Abstract
A clamp assembly (10) is provided which can include first and second clamp halves (16, 18) with a base (50) mounted in each clamp path. The base has a cylindrical inner surface (54) which can clamp a cable thereto for strain relief. Alternatively, a flexible insert (86) having a plurality of cylindrical cavities (102) opening through the outer surface (100) thereof can receive a number of cables (12) to be clamped in the clamp assembly for strain relief. In another version, a plurality of nested inserts (106-116) can be provided on each base (50) allowing the selection of a particular insert dimension suitable the cable to be secured.
Claims25
A clamp for clamping a cable to a support, comprising:
- a first clamp half having a base, a hinge portion, a forward portion and a securing portion, the base of said first clamp half having at least one hole therethrough to receive a securing fastener to fasten the clamp to the support;
- a second clamp half having a base, a hinge portion, a forward portion and a securing portion;
- the first and second clamp halves hinged together at their hinge portions and movable relative each other between an open and closed position;
- and
- a member between said clamp halves, said member having a surface for strain relief engagement with said cable with the clamp halves in the closed position.
A method for clamping a cable within a clamp, comprising the steps of:
- placing the cable between a first clamp half having a portion and a second clamp half having a base, a hinge portion, a forward portion and a securing portion, the first and second clamp halves hinged together at their hinge portions and movable relative each other between an open and closed position;
- moving the first and second clamp halves together to the closed position;
- securing the base of the first clamp half to a fixed support;
- and
- removing nested inserts from each clamp half until an insert is exposed having an inner surface with diameter corresponding to the diameter of the cable to be clamped.
A clamp for clamping a cable to a support, comprising;
- a first clamp half having a base, a hinge portion, a forward portion and a securing portion;
- a second clamp half having a base, a hinge portion, a forward portion and a securing portion;
- the first and second clamp halves hinged together at their hinge portions and movable relative each other between an open and closed position;
- a member between said clamp halves, said member having a surface for strain relief engagement with said cable with the clamp halves in the closed position;
- and
- wherein the member includes a clamp base mounted on each of said clamp halves, each of said clamp bases having a first projection engaging the forward portion and a second projection engaging the hinge portion, the base having a outer surface engaging the base of the clamp half and a curved inner surface.
A clamp for clamping a cable to a support, comprising;
- a first clamp half having a base, a hinge portion, a forward portion and a securing portion;
- a second clamp half having a base, a hinge portion, a forward portion and a securing portion;
- the first and second clamp halves hinged together at their hinge portions and movable relative each other between an open and closed position;
- a member between said clamp halves, said member having a surface for strain relief engagement with said cable with the clamp halves in the closed position;
- and
- wherein the hinge portion and forward portion of each of said clamp halves has an aperture formed therethrough.
A clamp for clamping a cable to a support, comprising;
- a first clamp half having a base, a hinge portion, a forward portion and a securing portion;
- a second clamp half having a base, a hinge portion, a forward portion and a securing portion;
- the first and second clamp halves hinged together at their hinge portions and movable relative each other between an open and closed position;
- a member between said clamp halves, said member having a surface for strain relief engagement with said cable with the clamp halves in the closed position;
- and
- wherein the securing portion of the first clamp half has a threaded rod thereon and the securing portion of the second clamp half has a cutout to receive the threaded rod, the clamp further having a threaded nut for threading on the rod to secure the clamp in a closed position.
A method for clamping a cable within a clamp, comprising the steps of:
- placing the cable between a first clamp half having a base, a hinge portion, a forward portion and a securing portion and a second clamp half having a base, a hinge portion, a forward portion and a securing portion, the first and second clamp halves hinged together at their hinge portions and movable relative each other between an open and closed position;
- moving the first and second clamp halves together to the closed position;
- securing the base of the first clamp half to a fixed support;
- and
- mounting a clamp base on each of said first and second clamp halves, the clamp base having the first projection and a second projection by inserting the first projection of each clamp base in an aperture provided in the forward portion and the second projection of the clamp base within an aperture in the hinge portion to secure the clamp base within the clamp halves.
