An electrical device including an electrode arrangement having a magnet, and an electrode, an electrically conducting movable device, movable relative to the electrode arrangement and spaced apart from the electrode arrangement, whereby a gap (G) is formed therebetween, and a suspension including a liquid, a plurality of magnetic particles dispersed in the liquid and a plurality of non-magnetic electrically conducting particles dispersed in the liquid, which non-magnetic electrically conducting particles have higher electric conductivity than the magnetic particles, wherein the suspension) extends between the electrically movable device and the electrode arrangement in the gap (G), and wherein the magnet is arranged to provide a magnetic field through the suspension to thereby align the non-magnetic electrically conducting particles between the electrode arrangement and the electrically conducting movable device to obtain an electrical connection between the electrode arrangement and the electrically conducting movable device.

An adapter having a rotatable plug is provided. The adapter includes a case having an installation hole which provides access to an interior of the case; a rotation member installed within the installation hole of the case, the rotation member being rotatable within the installation hole relative to the case; at least one connection pin installed in the rotation member and protruding from the case; and a guide member provided adjacent to installation hole in the interior of the case and configured to guide rotation of the rotation member.

A power connection device is provided for transmitting electric power from an external power source to a working machine). The working machine has an undercarriage and a superstructure, and the undercarriage and the superstructure are pivotable relative to each other about a substantially vertical pivot axis. The power connection device includes a first power conductor member which is adapted to be pivotally arranged relative to the undercarriage and the superstructure about the substantially vertical pivot axis.

A primary molded body having an angled connector that is integrally connected to an insulating annular body provided in a stator of a motor section, and that has a plurality of terminals extending along an axial direction of the motor section; a through-hole that is formed in the primary molded body and runs through the angled connector from an interior of the insulating annular body; a secondary molded body that is molded so as to cover the primary molded body; a secondary molded connector that is formed in the secondary molded body and covers the angled connector; and a connector opening that is formed in the secondary molded connector and communicates with the through-hole, wherein an outlet of the through-hole communicates with the connector opening.

A rotating contact device is described. The rotating contact device can include a contact ring and a pair of legs extending from a lower ring surface of the contact ring. Along an upper ring surface of the contact ring can be disposed one or more raised contacts. The rotating contact device can also include an inside contact held within an inside of the contact ring. Application of a downwards force on the upper ring surface of the contact ring causes the pair of legs to deflect and the contact ring and the inside contact to rotate and translate. When mated with opposing contacts, this rotation can function to radially wipe the opposing contacts and the upper ring surface.

In accordance with one embodiment, an image forming apparatus includes an image forming section and a transfer roller. A support body supports the image carrier in a main body opposite to the transfer roller. A holding member positioned in the support body holds the transfer roller. The holding member includes at least one groove in a portion of the holding member that holds the transfer roller. At least one conductive member is positioned in, and protruding from, the at least one groove so that a part of the conductive member makes electrical contact with the transfer roller when the transfer roller is held in the holding member. A power supply section applies transfer bias between the image carrier and the transfer roller through the conductive member.

The present invention relates to a brush type contact material, including one or more curved metal pawls of which ends come into contact with objects to be contacted. The ends of the pawls have an arc-like cross section in a thickness direction, a curvature radius R1 on a front side from a contact point with the object to be contacted and a curvature radius R2 on a back side from the contact point are formed so as to be R1R2, and also both ends in a width direction of the pawl are chamfered. At this time, preferably, R1 is larger than R2 (R1>R2), and R1 divided by R2 (R1/R2) is 3.0 or less. The brush type contact material according to the present invention enables a smoother sliding movement than ever before and can be relatively simply manufactured.
