Clamping device for self-supporting electric cables

摘要

A support for electric cables, in instances where the configuration of the distribution system is not fixed, comprises a pair of cable-clamping members whose outer surfaces form wedges guided by a pair of converging flanges. The inner surfaces of these members clamp the point or region of a cable that is to be held fixed in space. A pair of outer clamping members surround the above flanges. Coupling formations ensure that all parts of the structure always stay in their proper relative positions, allowing but a widening or a narrowing of the cable-receiving cavity. The flanges have projections or abutments which enter into lateral elongated recesses of the cable-clamping members and thus limit the possible minimum and maximum spacing of the latter, which depends upon the size of the electric cable that is to be supported.
