Abstract

A clamp for suspending a conductor from a support structure includes a body and a cover, each provided with a conductor-supporting surface having a trough and a set of upstanding tabs lining the sides of the trough and protruding from the conductor-supporting surface. The tabs on the cover are spaced from the tabs on the body in the longitudinal direction of the troughs such that the two sets of tabe intermesh when the cover is positioned on the body. The cover is movable between first and second positions in which the troughs, together with the two sets of tabs, enclose the circumferential surface of a conductor retained in the aparatus. A plurality of conductors may be accommodated by a single clamp construction.

Claims

1. A clamp apparatus for suspending a conductor from a support structure, the clamp apparatus comprising:

a body having means for engaging the support structure and for positioning the body relative to the support structure, the body including a first conductor-supporting surface provided with a first trough having opposed sides and a curved wall surface, and a first set of upstanding tabs lining both sides of the first trough and protruding from the first conductor-supporting surface;

a cover including a second conductor-supporting surface provided with a second trough having opposed sides and a curved wall surface, and a second set of upstanding tabs lining both sides of the second trough and protruding from the second conductor-supporting surface, the second set of tabs being spaced from the first set of tabs in the longitudinal direction along both sides of the troughs such that the first and second sets of tabs intermesh when the cover is positioned on the body,

the cover being movable relative to the body between first and second positions in which the troughs, together with the first and second sets of tabs, define conductor-retaining structure having a closed circumference such that the circumferential surface of a conductor retained in the apparatus is completely surrounded,

the circumference defined by the conductor retaining structure being smaller when the cover is in the first position than when the cover is in the second position so that the apparatus is capable of suspending any of a plurality of conductors having different diameters from one another; and

securing means for pressing the cover onto the body and holding the clamp apparatus against the support structure.

2. The clamp apparatus as recited in claim 1, wherein the means for engaging the support structure and for positioning the body relative to the support structure includes a plurality of legs provided on the body and extending away from the first conductor-supporting surface.

3. The clamp apparatus as recited in claim 1, wherein the body and cover are each provided with a hole through which the securing means passes, the securing means including a threaded rod secured to the support structure, and a nut that may be threaded onto the rod to press the cover against the body.

4. The clamp apparatus as recited in claim 1, further comprising positioning means for positioning the cover on the body and for permitting relative pivotal movement of the cover between the first and second positions.

5. The clamp apparatus as recited in claim 4, wherein the positioning means includes a ridge provided on the first conductor-supporting surface of the body and extending in a direction parallel with the first trough, and a groove provided in the second conductor-supporting surface adapted to bear against the ridge.
