Apparatus and methods for wire insulation in transmission line based electric fence are described in this invention. An insulator holds a wire pair that form the transmission line in its wire clamps. The insulator has a rain shed that sheds the wire clamps from getting wet by rain water. The insulator also has a pair of rain water divert guides that guide rain water accumulated on the wire to flow to the guide instead of to the wire clamps. This invention also describes a wire heating method that uses electric current to heat the fence wires such that the wire/wire clamp contact point will be kept dry and ice, snow accumulated on fence wires will be melted. Performance of the transmission line based electric fence can thus be greatly improved in advert weather conditions.

A new wire holder design. The holder is installed into a T-shaped or L-shaped hole in substrate such as a sheet metal, printed wiring board, etc. using only a single installation motion. The holder holds wires in place. Because it requires only a single installation motion the holder is easily installed and furthermore cannot rotate once installed. The holder protrudes only about a millimeter below the substrate.

A bracket (10) holds a wire (12) adjacent a magnetic surface (15). The bracket (10) includes a retaining member (14) with a magnetic attracting end (16) and a retaining end (18). The retaining member (14) is shaped to accept the wire (12) between the magnetic attracting end (16) and the retaining end (18) while holding the wire (12) adjacent the magnetic surface (15) when the retaining member (14) is held to the magnetic surface (15). The retaining member (14) is formed of a plastic material that is flexible to form a plurality of holding shapes and sturdy to retain one of the plurality of holding shapes to correspond to the magnetic surface (15) of a planar or non-planar configuration. The magnetic attracting end (16) and the retaining end (18) can each include a cavity (46) to receive and fit magnetic attractors (36, 38). The magnetic attractors (36, 38) can each have a length longer than a width and have elongated magnetic forces which are generally perpendicular to an axis extending between the magnetic attracting end (16) and the retaining end (18) of the retaining member (14). In other aspects, the wire (12) is held on a nonmagnetic surface by placing the wire (12) adjacent to the nonmagnetic surface and to first and second magnet attractive fasteners (22, 24) that have been attached to the nonmagnetic surface. While constraining the wire (12) within the bracket (10), the first and second magnetic attractors (36, 38) are attached to the first and second magnet attractive fasteners (22, 24), respectively, thereby holding the wire (12) adjacent the nonmagnetic surface.

The invention relates to a composite column insulator with a pulltrusion rod as the inner core, which is used in power transformation and transmission in power industry, and a producing method of the insulator. The invention consists of a winding tube, a core stick, end connecting parts and an umbrella part. The end connecting parts are separately stuck on the two ends of the winding tube. The invention is characterized in that: the winding tube is arranged at the periphery of the core stick, the integrated umbrella is stuck on the out side of the winding tube, and the umbrella is an injecting-formed part made of high-temperature vulcanization silicon rubber; the winding tube is made of epoxy resin adhesive emerged glass roving which is wound and solidified; the pulltrusion rod is used as the inner core of the insulator, so the problem of hollow insulator leakage is avoided; the high strength pulltrusion rod as the inner core of the winding tube greatly increases mechanical performance of the insulator; when producing the winding tube, a track is first simulated, and then pins are fixed on both ends of the core stick. When winding, a tension mechanism with even and constant tensile force is used for control, thus realizing even paving of the glass fiber.

The invention relates to a core rod of an ultra-high-voltage post composite insulator used for power transmission and transformation in the power industry and a manufacturing method thereof. The core rod consists of a rod core and a winding tube, wherein the winding tube is arranged on the periphery of the rod core and is a tube made by winding and curing a glass fiber yarn dipped with epoxy resin glue. The core rod is characterized in that the rod core is a core body with a damping slot on the surface thereof, and the winding tube consists of a layer I, a layer II and a layer III, and the three layers are respectively formed by winding and curing a glass fiber yarn dipped with epoxy resin glue. Since the pultrusion rod is used as an inner core, and the damping slot is processed on the surface of the rod core, the connection between the rod core and the winding tube is more reliable; and since the winding tube consists of multiple layers and forms a large-diameter core rod through laminated winding and curing, the invention improves the performance of the winding tube, is applicable to the ultra-high-voltage condition and greatly improves the wind resistance and bending resistance of the post composite insulator.

Disclosed herein are an insulating base plated with a metal layer, a plating method thereof, and a transparent electrode including the insulating base. During the manufacture of a polymer layer, a structure of an interface layer between a surface of the polymer layer and a metal layer is modified, adhesion with metal is excellent and the polishability of the interface layer is reduced, and thus, the reflectivity of the metal layer is reduced and particular color impression of metal is reduced to obtain black-oxide treated properties. When the metal layer formed on the insulating base is used in a mesh-type transparent electrode having a fine pattern, sufficient adhesion with metal for forming a pattern is obtained and the reflectivity of an adhesion layer of the metal layer is reduced, thereby increasing the visibility. Accordingly, the insulating base may be suitable for products such as transparent electrodes or touch panels.

A device connects a wire harness to a structure. A fixation portion of the device is secured to the structure. A spacing portion is connected to the fixation portion and to a connector portion. A retaining clip on the connector portion deforms when a wire harness connector component moves axially toward the fixation portion. The clip opposes an abutment edge against the component into engagement position when the component is past the clip to prevent it from moving back onto the clip. An abutment surface contacts another portion of the component in engagement position to prevent further axial movement of the component toward the fixation portion. The component is held captive between the edge and the abutment surface. Also provided are a cable support for connecting the wire harness to the device, a method for connecting and disconnecting the wire harness to a structure with the device, and an aircraft.
