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 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.

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.

A circuit breaker housing for holding a switching device unit and a number of connection contacts for a connection line and/or a busbar. The housing has a first housing part and a second housing part. In the joined, assembled state, the housing parts form a front side and a rear side opposite said front side and at least one connection side and end faces located opposite one another. A holding chamber for a connection module having one of the connection contacts is provided on the front side and/or on at least one of the connection sides.

A connecting element for mounting an electrical circuit board to an electrical flat conductor, in particular a busbar, has a flat or substantially flat mounting surface for applying and mounting the connecting element to the circuit board, and a tulip contact for receiving the flat conductor in an electrically contacting manner. The tulip contact includes at least one clamping element and a support element, between which a receptacle for the flat conductor is provided, and wherein the tulip contact preferably extends at a mounting angle greater than 45° and less than 135° with respect to the mounting surface. An electrical circuit board having such a contact element, a terminal block having such an electrical circuit board, and a method for automated mounting of such a terminal block are also provided.
