Abstract
A cable clamp for securing an electrical cable to a support structure has two substantially similar half-shells, each half-shell including a concave inner surface terminating in a pair of abutting surfaces. The half-shells further include a pair of winged flanges offset a distance from the abutting surfaces. The lower half-shell can first be secured to a support structure using a pair of elongate members passing through the winged flanges of the lower half-shell and a plurality of fastening members. A cable can then be placed within a cable receiving region of the lower half-shell and the top half-shell can be secured to the lower half-shell, applying a clamping force to the cable without interference from the fastening members used to secure the lower half-shell to the support structure.
Claims13
A cable clamp for securing a cable to a support structure, comprising:
- a first and a second half-shell of substantially identical shape, each having opposing inner surfaces defining a cable receiving region, the opposing inner surfaces terminating in respective abutting surfaces;
- a pair of first flanges associated with the first half-shell, the first flanges comprising inner surfaces and outer surfaces, the first flanges being laterally adjacent the cable receiving region of the first half-shell, the first flanges having first bores for receiving elongate members, the inner surfaces of the first flanges being substantially perpendicular to the first bores, and the inner surfaces of the first flanges being vertically offset from the abutting surface of the first half-shell by a distance;
- a pair of second flanges associated with the second half-shell, the second flanges comprising inner surfaces and outer surfaces, the second flanges being laterally adjacent the cable receiving region of the second half-shell, the second flanges having second bores for receiving the elongate members, the outer surfaces of the second flanges being substantially perpendicular to the second bores, and the inner surfaces of the second flanges being vertically offset from the abutting surface of the second half-shell by the distance;
- and
- a pair of elongate members configured to facilitate coupling of the first half-shell to the second half-shell, each elongate member being capable of passing through respective first and second flanges;
- a pair of first adjustable fastening members configured to mate with the respective pair of elongate members and to engage the inner surfaces of the pair of first flanges for securing the first half-shell to a support structure independently from the second half-shell, the first adjustable fastening members having a thickness less than twice the distance of the vertical offsets;
- and a pair of second adjustable fastening members configured to mate with respective portions of the elongate members extending beyond an outer surface of the second half-shell and to engage the outer surfaces of the pair of second flanges for securing the second half-shell to the first half-shell.

A cable clamp for applying a clamping force to a cable, comprising:
- a first half-shell comprising an outer surface and an inner surface, the outer surface configured for placement against a support surface, the inner surface defining a cable receiving region of a substantially semi-circular shape and terminating at an abutting surface;
- a second half-shell comprising an outer surface and an inner surface, the inner surface of the second half-shell defining a cable receiving region of a substantially semi-circular shape and terminating at an abutting surface, the inner surface of the second half-shell being configured to oppose the inner surface of the first half-shell;
- a pair of first flanges associated with the first half-shell, the first flanges having upper surfaces, the first flanges being offset from the abutting surface of the first half-shell in a direction towards the support surface, the upper surfaces of the first flanges being positioned away from and substantially parallel to the support surface;
- a pair of second flanges associated with the second half-shell, the second flanges having upper surfaces, the second flanges being offset from the abutting surface of the second half-shell in a direction away from the support surface, the upper surfaces of the second flanges being positioned away from and substantially parallel to the support surface;
- a pair of elongate members configured to facilitate coupling of the first half-shell to the second half-shell, each elongate member being capable of passing through the respective first and second flanges;
- a pair of first adjustable fastening members configured to mate with the respective pair of elongate members and to engage the upper surfaces of the first flanges for securing the first half-shell to the support structure independently from the second half-shell, the first adjustable fastening members having a thickness less than a distance of the combined offsets of the first and second flanges;
- and
- a pair of second adjustable fastening members configured to mate with respective portions of the elongate members extending beyond an outer surface of the second half-shell and to engage the upper surfaces of the second flanges for securing the second half-shell to the first half-shell.

A method for securing a cable to a support structure, comprising:
- providing a first and a second half-shell, each half-shell comprising an outer surface, an inner surface defining a cable receiving region, a pair of abutting surfaces, and a pair of flanges offset from the abutting surfaces by at least half the thickness of first fastening members, each of the flanges having a bore and surfaces substantially perpendicular to the bore;
- positioning the outer surface of the first half-shell adjacent a support structure;
- passing elongate members through the bores of each flange of the first half-shell;
- securing the first half-shell and the elongate members to the support structure independent from the second half-shell using first adjustable fastening members to engage the flange surfaces of the first half-shell away from the support structure;
- positioning a cable within the cable receiving region of the first half-shell;
- after securing the first half-shell and the elongate members to the support structure, positioning the cable within the cable receiving region of the second half-shell by passing each elongate member through a respective bore of the second half-shell;
- securing the second half-shell to the first half-shell using second fastening members to engage the flange surfaces of the second half-shell away from the support structure.
