A wire harness including a metal pipe into which an electrical wire is inserted, a metal braided section that covers the electrical wire drawn out from the metal pipe and is formed by braiding metal bare wires that are made of a different type of metal from that of the metal pipe, and a joint pipe to one end of which the metal pipe is connected and to the other end of which the metal braided section is connected. The joint pipe is made of the same type of metal as the metal braided section or of an insulating material.

A tapered trunking bus for carrying electricity from a row of solar panel arrays to a safety switch. The trunking bus includes a number of combiner and junction boxes connected in series. Each successive combiner and junction box combines the output of the previous combiner and junction box, received on a conductor of a first cross-sectional area, with electrical current received from a pair of solar panel arrays and outputs a higher current on a conductor of higher cross-sectional area. The cross-sectional area of each conductor is chosen to match the current to be carried and to account for the distance to the next combiner and junction box. For lower current segments of the trunking bus, cables or wires in conduits, of increasing gauges, can be used between combiner and junction boxes. For higher-current segments, metal bus bars of increasing cross-sectional area can be used between combiner and junction boxes.

A shield conductor that shields an electrical wire includes a shield pipe and a metallic braid part that are connected together by a weld along a circumferential direction. The weld may be made by ultrasonic welding. The welding may be direct welding, or welding in which a welding member is melted and then hardened to connect the shield pipe and the metallic braid part together.

A connection arrangement for connecting an electrical conductor includes: a housing; a busbar; a clamping spring including a clamping leg transferrable into a clamping position and into a release position; a conductor connection space formed between a section of the busbar and the clamping leg of the clamping spring; a displaceably arranged guide element, which is in operative connection with the clamping leg of the clamping spring, the clamping leg being holdable in the release position by the guide element; a release element, which, in the release position of the clamping leg of the clamping spring, is in engagement with the guide element, the release element during insertion of the conductor to be connected into the conductor connection space being actuatable thereby such that the release element comes out of engagement with the guide element and the guide element is displaceable by a spring force of the clamping leg.

A device for preventing the intrusion of water or other liquids into the interior of an automatic splice. The device includes a series of fingers that contact the cable stranding and wick water away from the cable and out of the connector. These fingers could be integrally molded into the cable cone or molded as a separate piece and inserted. They could also be constructed of any typical brush material such as metal, plastic, rubber, or fiber. The fingers could be arranged in a variety of configurations.

A conductive component structure of rail-type terminal device includes a conductive component disposed in an insulation case body. The conductive component has a first section and a second section connected with the base section. The first section and the second section are respectively formed with a bow portion, a first portion and a second portion. A load arm and an elastic unit assembled with the load arm are disposed on the first section and/or the second section. The elastic unit includes a first elastic section and a second elastic section. The load arm passes through the first elastic section and at least a part of the second elastic section. When the load arm is displaced or moved, the first elastic section and the second elastic section respectively provide tension (or pushback force) and pulling force effect so as to improve the shortcoming of the conventional terminal device.

Power cable accessory assembly having: a power cable including: a conductor, and an electrical insulation layer arranged around the conductor, wherein the electrical insulation layer has a main section and an end section, the end section having a smaller diameter than the main section; a fastening device engaging with the electrical insulation layer in the end section, and a connector extending around the end section of the electrical insulation layer, the connector being mechanically connected to the conductor, wherein the connector has an inner surface provided with a structure that engages with the fastening device to maintain an axially fixed position between the connector and the electrical insulation layer.
