Abstract: An electric connection box in which cassettes of different kinds can be attached to side walls of one casing, and by doing so, the casing can have a design for common use, and also the degree of freedom of arrangement of the cassettes can be enhanced. In electric connection box, a casing (1) includes at least one casing-side retaining portion (5); at least one cassette (10; 11) is attachable to the casing (1), the cassette (10; 11) includes an attaching-side portion having a cassette-side retaining portion (16; 19); and at least two pairs of casing-side fitting guide portions (4, 14) are formed in a projected manner on a side surface of the casing (1). When the cassette (10; 11) is attached to the casing (1), the attaching-side portion is guided by one of the two pairs of casing-side fitting guide portions (4, 14), and the cassette-side retaining portion (16; 19) is engaged with the casing-side retaining portion (5).

Abstract: The threaded wallplate mounting lobes of a mounting strap are eliminated and replaced by a retainer made of thin, hard brass sheet metal. The retainer has a body portion fixed to the mounting strap at each of its two ends and an apertured lobe which takes the place of the lobes of the mounting strap. By contouring the shape of the apertures in the retainers, mounting fasteners may be forced through such apertures to assemble a wallplate to a mounting strap without the usual mating of fastener and threaded mounting lobes.

Abstract: A circuit box includes a housing having a front panel defining one surface of a circuit receiving chamber within the housing. A shelf is rigidly coupled to the housing and extends perpendicularly and outwardly from the housing. A lip extends substantially perpendicularly from an outer end of the shelf remote from the front panel and is substantially parallel to the front panel to define a cable receiving channel with the shelf and front panel. Cable tie wrap retainers can be located on the shelf and within the cable receiving channel.

Abstract: A security device for securing a device to store shelving units such as gondolas having a clamp made from two sections that are secured to the gondola by threaded fasteners. The device is enclosed in a outer housing formed by two sections that fit within one another that are secured together by threaded fasteners. The housing unit is then fastened to the clamp to complete the security unit.

Abstract: An electrical contact facilitates making a soldered connection between an insulated wire conductor and a circuit board. The contact includes a tubular contact body having a hollow interior. One end of the contact body has an insulation piercing edge which promotes penetration of the contact body through the insulation of the wire conductor and into the conductive core when the wire conductor is pressed against the edge of the contact body. The other end of the contact body is solderable to a circuit board. The hollow interior permits solder to be drawn by capillary action through the contact body and into the wire conductive core.

Abstract: An enclosure for telecommunications equipment has a base and a lid pivotally connected to the base. The enclosure has an aperture defined by aperture edges through which one or more wires can be fed. A first elastically deformable insert is attached to a mounting surface on the base and a second elastically deformable insert is attached to a mounting surface on the lid, both adjacent to the aperture, such that when the lid is closed, the first and second inserts deform under contact with each other and with any wires fed through the aperture to reduce the size of gaps between the wires and the aperture edges. In one embodiment, the inserts have slots that enable non-continuous deformations to provide better sealing characteristics.

Abstract: An overhead traction wire support which including a first plate and a second plate, the first plate having on at least one side at least one leg which can be fastened to a ceiling or a wall of a structure. A second plate, which is made of an electrically conducting material, is held at a distance from the first plate via at least one insulator. A current conductor, along which a current collector can slide, is fastened in an electrically conducting fashion to the second plate on the side which faces away from the first plate, and at least one current amplification line is arranged on the second plate parallel to the current conductor.

Abstract: A multilayer wiring structure having a flame-retardant property corresponding to the V-0 class in the UL 94 standard is provided without degrading the inherent properties of a benzocyclobutene resin. The multilayer wiring structure contains a lower-level wiring layer formed on a base material, a lower-level interlayer insulating layer formed to cover the lower-level wiring layer, and an upper-level wiring layer formed on the interlayer insulating layer, an upper-level interlayer insulating layer formed to cover the upper-level wiring layer, and a protection layer formed to cover the upper-level interlayer insulating layer. Each of the lower- and upper-level interlayer insulating layers is made of a benzocyclobutene resin. The protection layer has a flame-retardant or non-flammable property corresponding to the V-0 class in the UL 94 standard. The protection layer may be made of a flame-retardant material such as a fluororesin, a polyimide resin or an epoxy resin.

Abstract: An electric power busway system comprises a bus bar support housing with the opposite side plates of the housing shaped with troughs to hold the bus bars in their relative positions, preventing the bus bars from moving towards or away from one another and providing the necessary short-circuit protection and bending resistance. The metal side plates are preferably fastened together without the use of fasteners or the need for welding, through the use of a punch and die tool set. A protective insulating sheet is sandwiched between the insulated bus bars and the housing to protect the bus bar insulation coating from ruptures or tears. Clamping blocks are provided outside the protective busway housing to apply friction on the bus bars within, keeping them from sliding out of the housing assembly. The integral busway housing and clamping serve as a ground conduction facility, with the clamping blocks providing a mechanism to connect the busway section to an adjoining section.
