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.

An electrical connector includes an insulative housing, and a pair of contacts which are secured together by a clamp mounted within the housing. Each electrical contact includes a planar body, spring fingers extending from a first end of the body, and a coupling extending from the body to couple the electrical contacts to the housing. A first deflection zone between the clamp and first ends of the spring fingers allows the spring fingers to deflect in a lateral direction to receive the conductive component within the receiving space. A second deflection zone between the first ends of the spring fingers and the second ends of the bodies allow the bodies and spring fingers to deflect in the lateral direction when the conductive component is received within the receiving space, but the conductive component is not directly aligned with the receiving space.

A contact element for contacting electrotechnical components includes: a leadframe part made of an electrically conductive material, having a recess in a contact tab. The contact tab is formed to be curved at at least one location such that a curving line, along which a curvature is present, extends between a beginning and an end of the recess and runs transversely through the contact tab in a straight line.

An insulated connection system for connecting a first busbar and a second busbar to at least a first connector and a second connector. The second busbar including a bar orifice to connect the first connector to the first busbar. The insulated connection system including an electrically insulating casing defining: a first recess portion for accommodating a first connecting portion of the first busbar, a second recess portion for accommodating a second connecting portion of the second busbar, and a sleeve portion for accommodating a portion of the second busbar provided with the bar orifice. The insulated connection system further including a busbar positioning assurance (BPA) member of electrically insulating material configured to accommodate a portion of the first connector and to be received in the connector passage and the bar orifice.

A rail holding structure of rail terminal includes a case body and a grounding member received in the case body. Two lateral sides of the grounding member are connected in the case body for holding a preset grounding rail. The case body is formed with two lower sections respectively corresponding to two sides of the grounding member. A foot section extends from at least one of the two lower sections. A first connection side and a second connection side are disposed on two lateral sides of the foot section. The first and second connection sides are connected with an outer sidewall of the lower section to form a socket with an open top side. A tool can be extended into the socket to pull and extend the foot section. Via the lower section, the grounding member is driven to detach from the grounding rail or hold the grounding rail.

The present disclosure provides a circuit assembly that has a novel structure, with which it is possible to prevent the occurrence of a problem caused by an excessive repulsive force of a heat conductive member by controlling the repulsive force of the heat conductive member. A circuit assembly includes: a heat generation component; bus bars that are connected to connecting portions of the heat generation component; an insulating base member that holds the heat generation component and the bus bars; and an elastic heat conductive member that is in thermal contact with the bus bars. The bus bars press the heat conductive member in a mounting direction in which the bus bars are mounted on the base member. As a result of the bus bars abutting against bus bar positioning portions provided on the base member, the positions of the bus bars in the mounting direction are defined.
