Abstract: A cable management system for electronic patchboard and routing systems. Cables are fabricated in a uniform length with appropriate termination Functional sets of cables are bundled and enclosed in a distinctly identifiable bundling material. Bundles are wrapped around a reel which has features for removable attachment to a cabinet. Reels are removably mounted to the cabinet at locations chosen to facilitate neat cable dressing. Appropriate lengths of cable are unwound from the reel. Cables are connected to associated connection points while leaving excess cable lengths wrapped around the reel.

Abstract: A strain relief attachment (10) is provided for coupling to the combination of an electrical connector (12) and a cable (14, 90, 92) extending from the rear of the connector, to provide strain relief for the cable. The attachment includes a housing (40) having a through passage (46) and having a front housing portion (42) that receives the electrical connector and a rear housing portion (44) that passes the cable. The rear housing portion has a slot (102) on one side to enable the fixing of the cable by pressing sidewardly through the slot to press the cable against an opposite side of the housing rear portion. For large cables, a simple tie (106) wrapped tightly around the housing rear portion presses directly against the cable. For smaller cables, an insert (120) that is molded as part of the housing, slides through the slot and presses the cable against the opposite side of the housing, with a tie pressing the insert against the cable.

Abstract: An adapter for connecting two wiring ducts on respective opposite sides of a suspended ceiling includes a back portion which has an opening at one end and upstream of the reference plane for inserting a first wiring duct. The other wiring duct can be butt-jointed to its other end. A cover portion at least partly covers the back portion, which has a reference plane which in use is level with the lower face of the suspended ceiling. Applications include conveying electrical cables or conductors through a suspended ceiling.

Abstract: A raceway section forms part of a raceway system for routing, protecting and enclosing cabling, and includes a base member, which may be U-shaped, and two split covers independently removably attached to side walls of the base member, such as by a hook and buckle attachment system. The base member defines a cable receiving channel and a longitudinally extending top opening. The split covers each have a laterally extending cover portion, an outside edge portion, and an inside edge portion, wherein the split covers each cover a portion of the longitudinally extending top opening such that a substantial amount of the top opening is covered. The inside edge portions are juxtaposed to form a longitudinally extending slot sufficiently wide to allow the removal or insertion of a cable through the slot without removal of the split covers. For insertion or removal of larger cables or bundles, one or both split covers can be removed.

Abstract: In an umbilical, one or more steel rods, which provide strength and ballast, are wound helically within the umbilical along with the steel tubes and/or elongated active umbilical elements. These steel rods replace some or all of the thermoplastic filler elements that would otherwise be included within the umbilical. An umbilical according to an embodiment of the invention may include a plurality of steel tubes helically wound around a core, and at least one substantially solid steel rod helically wound around the core, the steel rod being arranged in a void between the steel tubes. Thus, the invention avoids the need to apply additional armoring layers to the outside of the umbilical for strength and ballast.

Abstract: A frangible cover, generally made of a synthetic material, such as plastic, which fits over and grips the “hot” or energized bus bars in an electrical breaker box and fits under the insulating panel fingers in the breaker box. In this arrangement, the novel frangible cover is locked in place in the breaker box until the installer acts to remove all or part of the cover. The cover is scribed in a pattern so that it can be partially removed one or more breakers at time as intended by the breaker installer. The physical configuration of the present invention is mated to the physical configuration of the breaker box itself. The present frangible cover is designed to mate with the extending finger of the phase line bus bar and engage the tab of the insulating strip as if it were a breaker or plurality of breakers.

Abstract: An improved apparatus for deconcentrating an electric field, surrounding a high voltage insulator. A clamp assembly centrally formed within a coronal ring permitting positive placement of the coronal ring about an insulator end fitting. The clamping assembly includes an integral clamp with a U-shaped opening for engaging a cylindrical portion of an insulator end fitting. Two keeper clamps are pivotally mounted superjacent to the integral clamp, each keeper clamp having a smaller U-shaped opening both of which engage a portion of the insulator end fitting and pivot toward each other between an insulator receiving position and an insulator securing position, securing the insulator between the integral clamp and the two keeper clamps. A captive fastener such as a bolt extends upwardly through the clamp and the keeper clamps to secure the keeper clamps in position against the insulator end fitting and the integral clamp to secure the corona ring in position relative the insulator end fitting.

Abstract: A threaded cable hanger attached to a stud includes a reverse (protuberant) dimple that provides a seat for the end of the stud, and permits the bar to make up to a full final turn to permit the bar to be in a desired orientation. A stud top containing the reverse dimple may be disposed across the path of the stud. The stud stop may slowly bend from a configuration extending toward the stud to a configuration extending away from the stud, during bending absorbing energy and resisting excessive torquing. A pair of overlapping arms may be provided, one of which is internally threaded to receive the stud and guide it toward the reverse dimple and stud stop. When a large external force attempts to pull the bar off the stud, or when torquing is extreme, the arms unfold and create a binding action on the stud.

Abstract: There is provided a structure for connecting a flat cable to bus bars. To this end, conductor strips are first exposed from the end portion of the flat cable. The inventive structure includes bus bars and conductor strips adhered to the bus bars, thereby forming a joint section including strip layers and strip gaps. The structure includes a first and a second insulator resin sheet respectively placed on a first and a second face of the joint section. At least the first insulator resin sheet is then configured such that it penetrates into the strip gaps and adheres to the second insulator resin sheet, so as to form insulating grooves. In this manner, narrow conductor strips of a flat cable and corresponding bus bars can be connected with sufficient mechanical strength, and their insulation is improved.

The cover assembly has an elongate planar center element with a plurality of hinges and a plurality of corner elements, which have a first component co-planar with the central element, and a second component depending normal to the first component disposed. The orientation of the first and second components may be changed when the cover is molded to be biased in a “remain-open” position.

Abstract: The present invention relates to a screening device having a base plate and at least one shaped strip which can be joined to a side edge of the base plate. In this case, a shaped strip can be designed as a contact shaped strip or as a spring shaped strip with a plugged-on contact socket connector, and can advantageously be joined respectively to opposite side edges of a base plate. The advantage of the screening device in accordance with the present invention is, in particular, the low height of the shaped strips and, resulting therefrom, the electromagnetic screening, extending virtually ideally in one plane, of the metal housing, in particular in the case of a plurality of screening devices arranged next to one another. With subracks, the screening device in accordance with the present invention can be used, for example, as a rear cover or as a front filler panel for unassigned module locations.
