A power supply system for shelving system includes a support arm, and an electrical supply device mounted on the mounting plate. The support arm includes a mounting hole, and a mounting plate disposed in the mounting hole. The thickness of the mounting plate is less that the depth of the mounting hole. The electrical supply device includes a circuit board, and a first protection cover covering the circuit board. The circuit board is clamping between the mounting plate and the first protection cover. A side wall of the first protection cover opposite to the circuit board is flush with a side wall of the mounting hole. The assembly of the support arm can be completed without being affected by the electrical supply device as long as the end of the support art can be inserted into the punched hole as the side wall of the first protection cover opposite to the circuit board is flush with the side wall of the mounting hole.

The present invention relates to a cavity filter including: an RF signal connecting portion spaced apart, by a predetermined distance, from an outer member having an electrode pad provided on a surface thereof; and a terminal portion configured to electrically connect the electrode pad of the outer member and the RF signal connecting portion so as to absorb assembly tolerance existing at the predetermined distance and to prevent disconnection of the electric flow between the electrode pad and the RF signal connecting portion, wherein a part of the terminal portion, positioned between the electrode pad and the RF signal connecting portion, is elastically deformed to absorb assembly tolerance existing in a terminal insertion port. Therefore, the cavity filter can efficiently absorb assembly tolerance which occurs through assembly design, and prevent disconnection of an electric flow, thereby preventing degradation in performance of an antenna device.

A spring connector includes: a conductive tube; a movable pin that has a tip end portion protruding from an opening of the tube along an axial direction of the tube; a movable body that is provided inside the tube and that has one end portion in contact with a rear end portion of the movable pin; and a spring that is provided inside the tube and that is configured to urge another end portion of the movable body in a direction in which the movable pin protrudes. The other end portion of the movable body is an inclined surface inclined with respect to the axial direction, and at least one of the one end portion of the movable body and the rear end portion of the movable pin includes a convex portion.

An electrical connector having a barrel or hollow cylindrical sleeve into which is inserted a cylindrical interface member adapted to accept a coil spring member on one end thereof. The interface member on its other end acts upon a cylindrical sphere or ball captured with the other end of the sleeve member. The ball is movable axially and rotationally within the sleeve to make electrical and mechanical contact with an external surface which may be either movable with respect to the ball or not perpendicular to the ball. The connector is formed to direct current to pass primarily through the sleeve and to bypass the spring.

The present disclosure provides a concentric conductor for conducting electrical power from a source to a receiving system or load. The concentric conductor includes one or more conducting tubes interior to an outer tube, extending concentrically around a central axis. The conducting tubes are affixed a head-end interface and a connector assembly at either end of the concentric conductors.

A plug connector provides an electrical connection to a conductor track connection of a printed circuit board. The plug connector has a first printed circuit board with a conductor track connection and a plugging region for plugging the printed circuit board into the plug connector. The plugging region extends parallel to the first printed circuit board. A contact element and/or a spring element is provided in the plug connector. The plugging region and the contact element and/or the spring element are arranged in such a way that, in a plugged state of the plug connector, the printed circuit board which is plugged into the plugging region is arranged parallel to the printed circuit board and the conductor track connection is arranged opposite the conductor track connection. An electrical connection of the conductor track connection to the conductor track connection is provided by the contact element and/or the spring element.

[Object] To provide a contact that can hold down effects caused by solder, even if an elastic contacting portion is extending from a location contacting a first member. [Solving means] The contact includes a base portion, an elastic contacting portion and a gap forming portion. The base portion is configured solderable on a component mounting surface of the first member. The elastic contacting portion is configured elastically deformable and relatively swingable with respect to the base portion, and when contacting a contacted surface of the second member, is configured to elastically deform to be in pressurized contact with the contacted surface. In the gap forming portion, a concave portion is provided between a first end portion and a second end portion, and is configured to have a gap between the concave portion and the component mounting surface when the base portion is soldered on the component mounting surface in a state in which the concave portion and the component mounting surface are oriented in directions facing each other.

A shelving system having a detached power supply apparatus includes at least a hollow vertical shelf rail, at least a bus bar inserted into the vertical shelf rail, and at least a detached power supply apparatus inserted in the vertical shelf rail and electrically connected to the bus bar. Each of the vertical shelf rails includes at least a punched hole, and two locating protrudes. Each of the bus bar includes a slot, and two current conductors. The slot includes a carrier surface, and a track abutting surface. Each of the detached power supply apparatus passes through the punched hole and is inserted between the carrier surface and the track abutting surface. Each of the detached power supply apparatus includes two push-in resilient ball head plungers, a receiving surface, an abutting surface, and two reeds. The abutting surface is engaging with the track abutting surface.

A connecting element for at least two energy storage cells, having a metal sheet for the electrical connection of the energy storage cells. The metal sheet has at least two perforations for the uptake in each perforation of at least a part of an energy storage cell. Two lugs provided on the metal sheet project into the perforations.
