An electrical device arrangeable in a row with other electrical devices includes: a first bus section contactable with a further electrical device arranged on a first side of the electrical device; a second bus section contactable with a further electrical device arranged on a second side of the electrical device facing away from the first side; and a contact device, to which an electrical assembly is connectable, and which includes a contact element for establishing an electrical connection between the first bus section and the second bus section when the contact device is not connected to the electrical assembly, and, when the contact device is connected to the electrical assembly, is displaced in order to disconnect the first bus section and the second bus section from one another.

In various representative aspects, an assembly for connecting and electrically bonding two solar panel rail guides. More specifically, the assembly provides a splice that slides within two solar panel rail guides and includes an elongated spring element that is inserted into an elongated slot in the splice and enables the two solar panel rail guides to be electrically bonded together when various bonding techniques are used to allow portions of the spring to penetrate the oxidation layers of the inner surfaces of the rail guides as they are joined together. Another embodiment that utilizes a bonding element that is inserted into an elongated slot of a splice and also enables two solar panel rail guides to be electrically bonded when the rail guides are joined.

A terminal module (10) has a metal case (20) with a ceiling wall (21), a bottom wall (51) facing the ceiling wall (21), opposed side walls (23) extending from the ceiling wall (21) toward the bottom wall (51) and retaining pieces (24). A coil spring (40) is sandwiched between the ceiling wall (21) and the bottom wall (51). The retaining pieces (24) face each other in a direction perpendicular to a facing direction of the side walls (23) and project toward the bottom wall (51) from the periphery of the ceiling wall (21). The side walls (23) and the retaining pieces (24) are disposed alternately on the periphery of the ceiling wall (21). A spring receiving portion (26) formed by the ceiling wall (21), the side walls (23) and the retaining pieces (24) receives an end part of the coil spring (40) on the side of the ceiling wall (21).

A conductor assembly structure for a rail-type terminal device includes a conductor assembly and an insulating housing. The conductor assembly structure can reduce manufacturing waste and has a larger contact surface and a better electric conduction effect. The conductor assembly has a base portion that can be pivotally connected with a conductive connector, and a first area and a second area connected to the base portion. The first area and the second area are respectively formed with a bowed portion and a first section and a second section connected to the bowed portion to be snapped onto a grounding mounting rail. At least one of the first area and the second area is provided with a load arm and an elastic member connected to the load arm for increasing the elastic fixing effect (force) of the first section and/or the second section on the grounding mounting rail.

A single element electrical connector includes a single conductive contact element formed into a cage structure having a wire insert end and a wire contact end along a longitudinal centerline axis of the connector. The cage structure defines an upper pick-up surface having a surface area suitable for placement of a suction nozzle of a vacuum transfer device, as well as a pair of contact tines biased towards the centerline axis to define a contact pinch point for an exposed core of a wire inserted into the connector. A contact surface is defined by a member of the cage structure for electrical mating contact with a respective contact element on a component on which the connector is mounted.

An electrical connection terminal includes: a connection terminal housing having a conductor insertion opening; a busbar arranged in the connection terminal housing; a spring element rotatably mounted in the connection terminal housing and pivotable into an open position and into a closed position, a conductor inserted into the conductor insertion opening being clampable against the busbar by the spring element in the closed position; and an actuation element rotatably mounted in the connection terminal housing and by which the spring element can be actuated for transfer into the open position and into the closed position. The actuation element includes a base body, which has a tool insertion opening, and an actuation arm. The base body and the actuation arm are formed in two parts, the actuation arm being formed pivotally movable relative to the base body.

A single element connector includes a first cage-like structure configured to receive a wire. The first cage-like structure includes an insert end and a single contact tine coupled to a top wall of the first cage-like structure. The single contact tine extends downward from the top wall to a base of the single element connector and directs a wire inserted into the single element connector to the base of the single element connector.

An electronic-component-equipped terminal block includes a terminal block including first and second through holes provided in a front wall; an electronic component including a component body first and second leads; and an electrically insulating attachment assistance tool. The attachment assistance tool includes a base portion arranged outside a housing such that a rear surface thereof abuts against the front wall; and first and second insertion portions protruding from the rear surface of the base portion to be thereby inserted into the first and second through hole, respectively. The attachment assistance tool is provided with a first passage portion through which the first lead is inserted, and a second passage portion through which the second lead is inserted, and a receiving portion that receives and accommodates a rear portion of the component body is provided at a front-side position.
