Drop wire clamp
View Patent ↗A compression-type drop wire clamp that avoids damaging a signal carrying portion of a cable by applying a compressive force primarily to a support portion of a cable is disclosed herein. A plurality of holes may be included in a compression portion of the clamp to increase the frictional force between the cable and the clamp. An abrasive coating, such as an enamel and crushed glass mixture, may be added to the clamp to increase the frictional force between the cable and the clamp. Tines or other aligning mechanisms may also be used to center the cable in the clamp and/or to align other portions of the clamp (e.g. a shim).
1. A clamp to support a cable, the cable including a transmission portion and a support portion, the clamp comprising:
a housing defining an interior configured to receive at least a portion of the cable, the housing defining a first plurality of holes or dimples configured to engage the cable, wherein the housing includes a pair of side walls and a center base, the center base defining the first plurality of holes or dimples, the center base including a first recess for receiving primarily the transmission portion of the cable, wherein the plurality of holes or dimples are defined by two longitudinal rows, with a first longitudinal row disposed between the first recess and a first side wall of the housing and a second longitudinal row disposed between the first recess and a second side wall of the housing;
a slide receivable in the housing to create a clamping force between the slide and the housing;
a shim being disposable in the housing between the housing and the slide, the clamping force causing a surface in the housing associated with the first plurality of holes or dimples to grip primarily the support portion of the cable; and
a hanger attached to at least one of the housing, the slide, and the shim to support at least one of the housing, the slide, and the shim.
2. The clamp of claim 1 , wherein the first recess is free of holes and dimples.
3. A clamp to support a cable, the cable including a transmission portion and a support portion, the clamp comprising:
a housing defining an interior configured to receive at least a portion of the cable;
a slide receivable in the housing configured to create a clamping force between the slide and the housing;
a shim being disposable in the housing between the housing and the slide, the shim defining a plurality of holes or dimples for engaging the cable, wherein the plurality of holes or dimples are defined by two longitudinal rows, with a first longitudinal row disposed on a first side of the recess, and a second longitudinal row disposed on a second side of the recess, wherein the shim includes a recess for receiving primarily the transmission portion of the cable, the clamping force causing a surface in the shim associated with the plurality of holes or dimples to grip primarily the support portion of the cable; and
a hanger attached to at least one of the housing, the slide, and the shim to support at least one of the housing, the slide, and the shim.
4. The clamp of claim 3 , wherein the recess is free of holes and dimples.
