A grounding system for a rackable circuit breaker includes a finger cluster connector connected to a grounding bus in the circuit breaker and a rail conductor mounted in a circuit breaker cradle and connected to ground potential. The finger cluster connector includes a conductor formed from a single plate of conductive material folded into a generally U-shaped body with first and second sides divided into a plurality of fingers. Distal ends of the fingers form mutually facing parallel surfaces of a constricted passage configured to make a sliding electrical contact with the rail conductor that is advanced into the constricted passage as the circuit breaker is racked into the cradle. First and second leaf springs fastened to the conductor portion are divided into a plurality of spring finger sections with spring distal ends configured to respectively press against the distal ends of respective fingers of the conductor portion.

A terminal 12 to be connected to a front end part of a wire 11 in an extending direction is provided with a terminal body 15 including a wire connecting portion 20 to be connected to the wire 11, and a shell to be externally fit to the wire connecting portion 20. The wire connecting portion 20 includes a sandwiching portion 18A, 18B extending in the extending direction of the wire 11 and configured to sandwich the wire 11. The shell includes a resilient pressurizing portion for resiliently pressurizing the sandwiching portion 18A, 18B toward the wire 11.

Provided are load bearing universal adaptors for connecting electrical cables in a watertight configuration. The mechanical advantage associated with wedges in a tapered cavity ensures that load is appropriately transferred to the walls of the wedge housing and, as the load increases, the gripping force on the electrical cable increases. In this manner, a load applied to the electrical cable is at least partially provided to the walls of the system rather than acting to pull the cable out of the adaptor, and the object to which the adaptor is connected, such as a terminal block.

A connector comprises a pair of terminals for clamping and electrically connecting to a first conductive member. A first terminal includes a plurality of first elastic arms arranged in a row, with each first elastic arm having a first contact and a third contact formed thereon. The second terminal is laminated on an outer side of the first terminal and includes a plurality of second elastic arms arranged in a row. Each second elastic arm includes a second contact formed thereon. Each second contact protrudes to an inner side of the first elastic arms from a gap between two adjacent first elastic arms. The plurality of second elastic arms respectively abut against the outer sides of the plurality of first elastic arms. The first contact, the second contact and the third contact are adapted to be in electrical contact with the inserted first conductive member simultaneously.

A contact apparatus having at least one conductive, elastic, structured contact unit that may assume a first state and a second state and may be brought by supplying energy, such as pressure, from the first state into the second state, is provided for a particularly rapid and simple electrical contacting with a ground potential of cable shields of electrical cables with different diameters. The contact unit is configured so that, in the first state, the contract unit has a preparation for detachably inserting a plurality of electrical cables, and that, in the second state, the contract unit fixes the cables and establishes an electrical contact with the cable shields of the cables.

A first sheet metal is provided with slits. Elastic pieces having flat shapes are each formed between the slits adjacent to each other, and both ends of each of the elastic pieces are connected with both ends of an adjacent one of the elastic pieces. A second sheet metal is provided with protrusions each of which is protruded toward a corresponding one of the elastic pieces.

A device includes a body portion and a moveable fastener extension coupled to the body portion. The moveable fastener extension is configured to be inserted in an opening of an electrical ground lug and an opening of an object to be grounded. The device further includes a handle coupled to the moveable fastener extension and configured to be operated by hand to manipulate the moveable fastener extension to secure the electrical ground lug to the object via the device.

The present disclosure relates to wire terminals and/or termination mechanisms arranged and configured for use with a wiring device The wire terminals may be used in any suitable line-voltage wiring device. The wire terminals are arranged and configured to selectively receive a distal end of a wire therein.

A connection terminal for connecting a first conductor and a second conductor, the connection terminal including: a connection configured to be connected to the first conductor; an arc-shaped fitting that extends from the connection, and is configured to be fitted to, while being in surface contact with, a tubular outer circumferential surface of the second conductor over a half of the circumference thereof, with application of restoring force after elastic deformation; and a pair of extensions that extend from two ends, in a circumferential direction, of the arc-shaped fitting, and are curved to a side opposite to a side to which the arc-shaped fitting is curved.

A connector assembly includes a first connector having a first insulator and a first contact, a second connector having a second insulator and a second contact and being fitted to the first connector along a fitting direction; a lever member held by one of the first insulator and the second insulator in a rotatable manner about a rotational axis, a rotational shaft member extending along the rotational axis and rotating in accordance with rotation of the lever member, the rotational shaft member having a cam surface for pressing the first contact and the second contact against each other, and a cam mechanism moving the first insulator and the second insulator relatively along the fitting direction in conjunction with rotation of the lever member.
