A connecting arrangement for a three-level converter arrangement includes a first to third connection rail which are each in the form of a shaped metal body. The respective connection rail has a line section and a connection section which has a connection means. The respective connecting rail has a line section and a connecting section which, for its part, has an associated respective connecting means. The respective connection means forms, with the connecting means, a force-fitting, electrically conductive connection. The connection rails are connected to the connecting rails with the correct polarity. The respective line sections of the connection rails and the connecting rails are situated one above the other in a stack, wherein the first connecting section, in projection in the normal direction of the first connection section, covers the first connection section; wherein the second connecting section, in projection in the normal direction of the second connection section, covers the first connection section and the second connection section, and wherein the third connecting section, in projection in the normal direction of the third connection section, covers the second connection section and the third connection section.

A connector comprises a pressing assembly and a contact prevention member. The pressing assembly has a first receptacle receiving a first conductor, a pressing member which can be activated from an exterior of the pressing assembly, and a chamber. The contact prevention member has a contacting slot open to an interior of the contact prevention member and a second receptacle receiving a second conductor. The contact prevention member is insertable into the chamber of the pressing assembly in an insertion direction.

A terminal base that is disposed on an electrical connection path between a coil of an electric motor accommodated inside a case and an inverter disposed outside the case and connects a coil-side terminal serving as a terminal on a coil side to an inverter-side wiring member serving as a wiring member on an inverter side, the terminal base including: a connector that electrically connects the inverter-side wiring member and the coil-side terminal; a fastener that fixes the coil-side terminal to a first terminal serving as one terminal of the connector; and a terminal base main body that holds the connector.

A ground connection structure includes a ground terminal fitting (20) with a bolt hole (28). Resilient locking pieces (29) are formed on an inner peripheral edge of the bolt hole (28) and are locked to an externally threaded portion (13) of a stud bolt (12). A rotation stopping portion (31) is formed on the ground terminal fitting (20) and is locked to a rotation stopping hole (14) of a plate-like ground member (10). A resilient retaining piece (32) is formed on the rotation stopping portion (31) and is configured to restrict separation of the rotation stopping portion (31) from the rotation stopping hole (14) by locking to an edge part of the rotation stopping hole (14).

A fastener includes a head and a shaft extending from a first end to a second end. The first end is attached to the head. The shaft includes an external thread proximal the second end and a nut having an internal thread and an internal diameter. The second end of the shaft has a first condition and a second condition. In the first condition, an external diameter of the second end corresponds to the internal diameter of the nut such that the internal thread of the nut mates with the external thread of the shaft to attach the nut to the shaft. In the second condition, the external diameter of the second end is greater than the internal diameter of the nut such that the internal thread of the nut does not mate with the external thread of the shaft and the nut, once attached to the shaft, does not detach from the shaft.

Provided is a thermocouple transition body apparatus comprising: a transition body, having at least one recess; a positive electrical terminal; a negative electrical terminal; and, at least one cap; wherein the transition body, positive terminal, and negative terminal are configured to attach to conductors without the use of epoxy or crimping. The thermocouple transition body apparatus is able to withstand temperatures exceeding 500 degrees Fahrenheit.

A battery post terminal assembly includes a conductive band and a clamp mechanism. The conductive band includes a first free end and a second free end. The conductive band defines an aperture for receiving a battery post of a battery. The clamp mechanism includes a wedge member that defines a recess between a first surface and a second surface thereof. The recess has an open end and a closed end that is narrower than the open end. The first surface is convex. The first free end and the second free end are positioned in the recess. The first free end is movable along the first surface toward the closed end to be moved by the first surface toward the second free end to tighten the conductive band around the battery post.

A connection device for connecting electrical conductors includes a sheath clamp comprising a bottom part and a top part, a contact carrier to which the bottom portion of the sheath clamp is attached, and a detachable insulating cap configured for rotabably receiving the top part of the sheath clamp, wherein the detachable insulating cap is permanently connected to the contact carrier.

A module-terminal block connection structure includes: a printed wiring board; a terminal block which is disposed on one surface of the printed wiring board and is formed into a three-dimensional shape by a conductive material, the terminal block being fixed to the printed wiring board; a power module which is disposed on the other surface (rear surface) of the printed wiring board and includes an electric circuit and a press-fit type lead pin used as a circuit terminal; and a conductive portion which is electrically connected to the terminal block, includes a hole (through-hole) for press-inserting the lead pin thereinto, and is electrically connected to the power module while the lead pin is press-inserted into the hole.
