摘要:
A line hanger for securing lines, such as transmission, pneumatic, hydraulic, electrical and other types of lines, to a support structure and a method of mounting and supporting one or more lines from a support structure. The line hanger includes an attachment support provision configured for mounting to the support structure and a pair of spaced-apart clamping arms depending outwardly from the attachment provision. The clamping arms are configured to resiliently separate for slidingly receiving an line and to resiliently relax for applying a clamping force to secure the line. Multiple line hangers may be interlinked or stacked relative to the support structure for support multiple lines.

A cable hanger for securing multiple cables to support structures including antenna towers and poles. The cable hanger has a hingeably-coupled pair of shell halves with recesses that, when folded, establish a pair of cable passageways. Gripping arms provided on each of the shell halves project into a corresponding one of the cable passageways for gripping a cable positioned therein. Pairs of gripping arms located on opposite shell halves have a confronting relationship for gripping the cable on diametrically opposite side surfaces.

A line hanger for securing lines, such as transmission, pneumatic, hydraulic, electrical and other types of lines, to a support structure. The line hanger includes a wire structure with an attachment section configured for mounting to the support structure and a pair of clamping arms depending outwardly from the attachment provision. The clamping arms are configured to resiliently separate to receive a line and to resiliently relax for applying a clamping force to secure the line. The clamping arms are clasped together by engaging hook members defined at the open end of the wire structure. Multiple line hangers may be interlinked or stacked relative to the support structure for support multiple lines.

A flat cable assembly for use with a mass termination connector. The cable assembly includes a main cable having a plurality of conductors held in regularly spaced parallel relationship in a sheet of insulation to match the terminal element spacing of the connector. The main cable has a first surface, a second surface and lateral ends with the surfaces extending between the ends. A plastic covering having an interior surface facing the main cable second surface is provided. A release agent is printed on either or both of the interior surface of the plastic covering and the second surface of the main cable so that portions of the printed upon surface are coated by the release agent and other portions of that surface are uncoated. A metallic ground plane is positioned between the main cable and the covering with the plastic covering being bonded to the second surface at the uncoated portions so that the plastic covering can be readily separated from the main cable to expose the ground plane.

A strain relief for an electrical conductor cord is disclosed for distributing a bending stress acting on the cord. The strain relief includes a head portion and a flexible tail portion molded about a conductor having a major transverse axis of greater dimension than its minor transverse axis. A bending force acting on the cord in a direction to effect bending about a bend axis nonparallel to the major transverse axis of the cord induces both bending and torsional movement of the strain relief so as to distribute the flexure strain over the length of cord within the strain relief and thereby increase the flexure life of the cord.

A bulkhead penetration system for interlocking with a wall to feed cable therethrough is set forth. The system includes a bulkhead member having a shoulder disposed between a collar portion and a locking portion. A plurality of flexible outwardly extending fingers are formed about the locking portion with each finger having a fixed end and a retaining end. The bulkhead member interlocks with the wall such that the wall is retained between at least one of the retaining ends and the shoulder. The distances between retaining ends and the shoulder can vary such that a single system will generally interlock with walls of different thicknesses. The system further includes a boot defining a boot split and a boot bore. The boot includes an inner surface, a first sleeve portion sized to encompass the collar portion, and a second sleeve portion. A grommet defining at least one cable aperture is adapted for being received within the boot bore. Two fasteners for applying force are positioned on the boot to close the boot split and engage the system components. A gasket is removably disposed between the shoulder and retaining ends for providing a tight-fit against the wall. A method for penetrating a wall using a bulkhead penetration system that allows at least one cable to be fed through the wall is also set forth.

A transmission line hanger is provided for attaching a corrugated transmission line to a supporting structure. The hanger includes a first section adapted to engage a first side of the transmission line and a second section adapted to engage a second side of the transmission line. The first and second sections define an inner generally cylindrical the gripping ribs forms a protrusion extending radially inward from the inner generally cylindrical surface. The gripping ribs are spaced to fit into corresponding recesses in the corrugated outer surface of the transmission line.In another embodiment, the hanger further includes a snap clasp having two elements. The first element is a lip on the exterior of the hanger. The second element is a latch having three sides.In still another embodiment, the hanger includes a first alignment pin and a first mating recess on the fist section and a second alignment pin and a second mating recess on the second section. The first recess being adapted to receive the second alignment pin and the first alignment pin being adapted to fit in the second mating recess to align the first section with the second section.

A flat cable for use with a mass termination connector having a plurality of regularly spaced terminal elements. The flat cable includes a laminated carrier film and a plurality of discrete conductors held in regularly spaced parallel relationship by the carrier film to match the terminal element spacing of the connector. Each conductor has an insulating jacket made of a thermoplastic material. The carrier film includes an attachment layer of thermoplastic insulatioln having a melting temperature similar to that of the jacket material, and a dimensional stabilization layer made of an insulative material having a melting temperature higher than those of the attachment layer and the jacket material and displaying dimensional stability at the melting temperatures of the attachment layer and jacket material. The jackets of the conductor are fused to the attachment layer, and the attachment layer is held by the stabilization layer. The carrier film can be longitudinally discontinuous to form first cable sections where the conductors are held parallel for ease of termination, and second cable sections where the conductors are not held to increase flexibility and reduce weight. The cable can also be formed into a round configuration to provide advantages during routing, and locating indicia can be applied to the outside surface.
