Abstract: A wire distribution member 40 consists of a plurality of electrical conductors 41 and wrapping members 42. The electrical conductors 41 comprise wires having a degree of rigidity whereby they maintain their own shape independently, and are bent along a prescribed wire distribution path which passes along electrical components including terminal fittings 24 and 26, switches 30 and 31, bulbs 50, and a connector member 16, etc. The wrapping members 42 are sheet-like and leave portions which join with the electrical components uncovered. These wrapping members 42 are joined together so as to maintain the electrical conductors 41 along the prescribed wire distribution path. As a result, each electrical conductor 41 does not need to be attached to the body 11 separately.

Abstract: A retention device for the installation of cabling includes a bottom surface for connecting the retention device to a support structure, and a top surface which is integrally connected to the bottom surface at a distance therefrom by an aft surface. The top surface includes at least two cable gripping members which define a passage for selectively housing the cable clusters. The gripping member is defined by a distal edge, a proximal edge and a structural area connecting them. The passage is defined by the distal edge and proximal edge of the adjacent gripping members and an aft edge of the aft surface. The aft edge engages the top surface in an off-set manner sufficiently large to generate clearance for, and reduce bending tension of, cable clusters which engage the retention device during installation. The gripping member further includes a forward end extension, integrally connected to the structural area of the gripping members.

The stud is provided to be inserted in each assembling hole in a mother board and a penetrating hole is installed therein. A circular buckling trench is installed at an outer periphery of the stud. The quick detaching cover has a cover piece for covering an opening of the screw hole of the stud. The periphery of the cover piece being formed with elastic clamping pieces extending toward the stud for clamping the stud so that the quick detaching cover is detachably assembled to the stud temporarily. Therefore, the stud with quick detaching cover is provided to a SMT automatic machine for absorbing the cover piece by vacuum for picking the stud to a predetermined position. Then, the stud is inserted into the assembling hole. Then, the stud is released so as to complete the assembly work. Therefore, the whole assembly work is quick, accurate and quick.

Abstract: A busway and a door assembly for use with the busway are described. The door assembly provides access to the conductive busbars through openings in the busway housing. The door assembly includes an insulator plate having openings therethrough for access to the busbars. The insulator plate includes two hinge grooves disposed on opposite edges of the insulator plate. Additionally, the door assembly includes a dual-hinged door which includes a pair of hinge rods adapted for engagement with the hinge grooves. By pivotally rotating on the first hinge rod within the first hinge groove, the door may be opened to a first position. Conversely, by pivotally rotating on the second hinge rod within the second hinge groove, the door may be opened in a second direction. Once in either open position, the door cannot be removed from the insulator plate. Additionally, insulator stabs extend from the insulator plate and are disposed between the busbars to prevent arcing between the exposed areas of the busbars.

Abstract: To prevent lightning from destroying equipment in a housing structure, a shield structure is built within the housing structure for enclosing electrical conductors that may allow surge currents to be routed into the housing structure. The shielding structure is constructed of ferrous or non-ferrous metal and preferably of the same material as that of the ground plane of the housing structure to which the electrical conductors are mounted. A terminal cover strip for enhancing efficient grounding is also disclosed.

Abstract: A composite insulator is provided. At least one metal end fitting is provided having a sleeve portion which defines a bore with a first diameter, d1. An insulator subassembly is then formed. The insulator subassembly includes a rod of electrically insulating plastic material and an insulator sheath covering at least a portion of the outer surface of the rod. An end portion of the sheath has a deformable circumferential ridge formed on the outer surface thereof. This circumferential ridge has a second diameter, d2, which is greater than the first diameter, d1. The insulator subassembly is then inserted into the bore of the metal end fitting with a spacer member interposed between the metal end fitting and at least the circumferential ridge. The spacer member serves to deform the ridge to define a temporary vent for allowing air within the bore to escape.

Abstract: A unitary protective stud bushing produced from a resilient plastic and including an elongated base having at least two distinct widths at either end and opposed longitudinal edges, and two rows of spaced apart teeth extending in splayed relationship from said longitudinal edges. Because of the distinct differences in the width of the base, the two rows of teeth are spaced apart different distances along the base such that when turned upon itself the teeth of the bushing along the narrower width nest within the teeth along the wider width. Because of the resilience of the plastic material, the bushing can be turned upon itself, inserted into a hole in steel structural member such that the teeth loosely engage either side of the periphery of the hole and the resilient plastic causes the base to spring open until the inside surface of the base contacts the periphery of the hole and the teeth engage opposing outer surfaces of the periphery of the hole.

Abstract: A raceway separated into multiple wireways by a dividing element is presented, said dividing element being supported by divider clips having an intermediate “U” shape to envelope three sides of the dividing element. Raceway base sections are joined by a raceway coupling particularly adapted to lie along the sidewall of each raceway base section being joined so as not to interfere with the dividing element.

Abstract: A lightning rod system including both methods and specific types of lightning rod protection apparatus, which address the need for lightning rod safety features to deter impalement and minimize injury when humans inadvertently fall upon or strike the projecting air terminal through use of a hebetative contagious impact surface (10) on an end cap(s).

Abstract: A hot swap tray having a housing adapted to be slidably inserted in a rack. The tray includes an electromagnetic shield member mounted for rotation about an axis traversing the sliding direction of the tray. The shield has a resting state in which the shield presents a first dimension in a plane traversing the sliding direction and a deflected state in which the shield presents a second dimension in the plane, the first dimension being greater than the second dimension. The shield is actuated on insertion of the tray into the rack to move from the resting state to the deflected state so that the shield clears adjacent shields located within the rack and from the deflected state to the resting state so that the shield engages the adjacent shields.
