A connection arrangement comprising a metallic flat conductor having an at least quadrangular cross-sectional profile and at least two opposing surfaces extending longitudinally parallel to each other at least in an end region, a first through-opening between the surfaces in the end region, the first through-opening being formed for receiving a bolt, at least one second through-opening between the surfaces in the end region, the second through-opening being formed to receive a metallic terminal, the terminal being formed as a flat part and bearing flatly with a contact surface against one of the surfaces of the flat conductor in the end region.

Provided is a current branching device for branching a current and supplying the current to a plurality of supply destinations, including a branch member welded to a main conductive wire at an intermediate portion of the main conductive wire for supplying a current to one supply destination, and at least one branch conductive wire welded to the branch member, for supplying a current to another supply destination.

A terminal unit 1 includes: a terminal fitting 10; and a holder 50. The terminal fitting 10 includes a connection portion 10A in which a bolt insertion hole 10C is formed, and the holder 50 includes a main body portion 50A that is configured to be attached to the connection portion 10A and a detent 50B that protrudes from the main body portion 50A and prevents the terminal fitting 10 from rotating.

A connection structure of an inductive element includes a circuit substrate, in inductive element, at least one connection wire, a supporting element, a containing element, a positioning element, a connecting element, and a locking element. The circuit substrate has a through hole. Each connection wire has a first end connected to the inductive element, and a fixed terminal is disposed on a second end of the connection wire. The containing element is formed on the supporting element to provide a containing space. The positioning element is contained in the containing space, and provides a positioning part. The connecting element has a first connecting part and a second connecting part. The first connecting part is connected to the positioning part to clip the fixed terminal. The locking element has a locking part. The locking part is connected to the second connecting part to lock on the circuit substrate.

An easily removable ground rod connector system for attaching grounding wires to a ground rod, which can be easily added to or removed from the ground rod even after the ground rod has been inserted into the ground and ultimately provides a safe and reliable connection and corrects several existing problems with current connectors.

A coupling system establishes an electric connection between two electric components. The first component is positioned in a housing and includes at least one busbar, and the second component is disposed outside the housing and includes at least one current connection. An electrically conductive connection can be established between the busbar and the current connection by the coupling system. The coupling system includes a plug insert which can be plugged into the housing. The plug insert includes an insulator part, in which a sleeve and a washer nut are fixed. The insulator part has a recess which is formed in such a way that the busbar can be moved between the sleeve and the disc nut through the recess. A plug insert for a coupling system is also provided.

A power feeder device can include a base having a mounting portion and a plurality of connector structures extending from the mounting portion and spaced apart relative to each other to form a respective gap therebetween. Each connector structure can be configured to receive a respective pair of terminals to electrically connect the respective pair of terminals within connector structures and to block a line of sight between adjacent pairs of terminals. The device can also include a cover configured to mate with the base to enclose each of the plurality of connector structures and to increase a length of a creepage path between each pair of terminals by at least partially inserting into each gap between the connector structures. The base and the cover can be configured to form a terminal opening on each lateral side when assembled to allow pass-through of a conductor and/or portion of each terminal. In certain embodiments, at least one of the terminals of the respective pair of terminals can be a bus bar extending from a bus bar chassis and the base and/or the cover can form a creepage barrier that extend into a chassis wall opening of the bus bar chassis to increase a length of a chassis creepage path from the respective pair of terminals to the bus bar chassis.

An appliance power connector includes a terminal block having a base. The base includes an upper surface and a lower surface. The base includes a pocket. The terminal block includes an upper shroud and a lower shroud. The upper shroud has upper shroud walls extending from the base forming an upper chamber above the upper surface. The lower shroud has lower shroud walls extending from the base forming a lower chamber below the lower surface. The appliance power connector includes a power terminal coupled to the terminal block. The power terminal includes a main body, an upper stud extending from a top of the main body and a lower stud extending from a bottom of the main body. The main body is received in the pocket. The upper stud is located in the upper chamber above the base for connection to an upper power cable terminal. The lower threaded stud is located in the lower chamber below the base for connection to a lower power cable terminal.

A connector system includes a barrel and a lug connector arranged at an end of the barrel. The lug connector has a first contact and a second contact separated by a clearance.
