This invention relates to an aluminum conductor composite core reinforced cable (ACCC) and method of manufacture. An ACCC cable (300) has a composite core and at least one layer of aluminum conductor (306). The composite core (303) comprises a plurality of fibers from at least one fiber type in one or more matrix materials. According to the invention, unique processing techniques such a B-Staging and / or film-coating techniques can be used to increase production rates from a few feet per minute to sixty or more feet per minute.

Amounting apparatus used to fasten a PCB (10) with through holes (12) includes a supporting board (20) and a plurality of clips (30) mounted on the PCB. The supporting board has a plurality of standoffs (22) corresponding to the through holes of the PCB. Each of the clips includes a resilient portion (34) and defines a mounting opening (35) for having the standoffs sliding therein. When the standoffs press on the resilient portions of the clips, the PCB is clamped on the supporting board.

A connector includes an apparatus-side connector housing attached to a casing of an inverter. The apparatus side-connector housing has a plurality of busbars. Each of the busbars has on one end portion a terminal fitting portion where a mating connector of the apparatus-side connector housing is connected and on the other portion an inverter-side terminal portion where an output terminal of the inverter main circuit board is connected. The busbars are divided and arranged into groups respectively corresponding to the U, V and W phases with respect to the inverter-side terminal portion. The busbars are arranged into groups respectively including the U, V and W three-phases for connection to each of the three-phase loads, with respect to the terminal fitting portion. A wire connecting inverter with a plurality of there phase loads can be arranged with respect to each of three phase loads with small space.

A molded plastic fence insulator including a pair of spaced apart sidewalls connected by a connecting wall, aligned grooves defined across the connecting wall, and retention members associated with the aligned grooves and configured for receiving the wires underneath a portion thereof.

An electrical power line insulator has an end clamp with a saddle for supporting an electrical wire, a track provided on a front surface of the saddle, a keeper for compressing and supporting an electrical wire seated in the saddle, a bolt and a nut for fastening the keeper to the saddle and operable to horizontally move the keeper along the track, and an insulator housing secured to the end clamp and mounted on a support structure. The end clamp and the insulator housing are detachably assembled with each other by means of a cylindrical clamp base integrally provided on a lower portion of the saddle and the track of the clamp and an upper fitting part. The upper fitting part has an assembly cylinder provided on an upper portion of the fitting part to be connected to the cylindrical clamp base, a compression cylinder provided on a lower portion of the fitting part and pressed against a post of the insulator housing, and a bolt and a nut fastening the cylindrical clamp base of the clamp to the assembly cylinder of the upper fitting part.

A number of examples of insulated conductors having geometrically optimized shapes and form factors, that may be used in twisted-pair cables and other types of communication cable to enhance the performance of, and / or reduce the cost of manufacturing such cables.

A high-voltage insulation device (300) for use in a charged-particle optical apparatus comprises a plurality of rigid pillars (320) made of electrically insulating material. These pillars (320) are arranged around a central passage (310) which traverses the insulating device along its longitudinal axis (L), and the two ends of each pillar are configured to be respectively fixed to two separate electrostatic housings (221, 231) of the charged-particle optical apparatus by means of two respective end plates (311, 312), with the pillars (320) being oriented at an angle so as to be inclined with regard to said longitudinal axis (L). Advantageously, the pillars are mechanically adjustable with regard to their effective length, and each pillar (320) is arranged outside the central passage with its two ends at either of the first and second end plates (311, 312), preferably in a zig-zag arrangement.

A connector for attaching a printed circuit board to other apparatus is formed as a separate connector body with a plurality of pins projecting from one end surface that are attached to the printed circuit board by being secured in vias through the board and a threaded opening at the end surface opposite the one end surface from which the pins project. When a bolt is received in the connector threaded opening and drawn tight to secure the printed circuit board to other apparatus, the stresses and material deformation induced by the securing bolt are isolated from the printed circuit board. Further, the attachment of the pins to the printed circuit board rather than the use of screws extending through holes in the circuit board reduces the size of ‘keep out’ zones that must be avoided by the wiring paths on each wiring surface of the printed circuit board through which mounting holes extend. Fabrication of the connector and assembly of the connector to the printed circuit board are facilitated by providing a pair of parallel side surfaces on the connector body which can be gripped by a tool. The connector can also be used to electrically insulate or provide a current path by the selection of the polymer that forms the connector body portion.

The high-voltage insulator for securing a high-voltage wire in an electrical plant or in an electric power line comprises an insulating body, the first end of which is used for mechanically connecting to a high voltage wire and / or to a fixing device, the second end being provided with a metal fixture which is fastened thereto and is used for attaching the insulator to a tower. In order to impart lighting protection properties to the insulator, it is also provided with a multi-electrode system consisting of m electrodes, which are mechanically coupled to the insulation body and are arranged between the ends thereof. The electrodes are disposed in such a way as to form an electric discharge between the adjacent electrodes, between the electrode adjacent to the first end of the insulation body and the high voltage wire or the fixture thereof and between the electrode adjacent to the second end of the insulation body and the metal fixture connected to the tower. The insulator is provided with means for compensating the reduction of the insulator creepage path caused by the multi-electrode system. The electric power line using the insulators of this type do not require lighting dischargers.
