A wiring terminal includes a housing, a clamping and connecting piece, and a pressing piece. The housing is provided with a mounting channel and an insertion hole communicating with the mounting channel. The clamping and connecting piece is provided with a curved spring plate for clamping a conducting wire and a conductive sheet. The spring plate has a natural state in which the conducting wire placed in the mounting channel is clamped between the spring plate and the conductive sheet through elastic abutment, and a pressed state in which the spring plate is controlled by external force to deform in a direction distal from a clamped conducting wire. The pressing piece is capable of triggering the spring plate to switch between the natural state and the pressed state to unclamp the conducting wire.

The electrical connector with cure-in-place resin is a twist-on wire connector with integrated resin injection, the resin curing around the enclosed conductors. The resulting connection is permanent, maintaining connectivity and excluding water. At the tip of the body, a sliding cartridge holds a single or multi-part resin within one or more sealed chambers. After the conductors are introduced into the body, and the connector tightened into place, the sliding cartridge is pressed into the body. The sliding causes the cartridge to compress against a piercing tip, causing resin to pass into the body of the connector, curing around the conductors.

The disclosure provides an insulator for an end of a cable, the insulator having a longitudinal body in which a central channel is provided, the insulator including a connector system arranged in the central channel, the system comprising a connection pin for receiving an end segment of the cable, the pin being shaped so as to present an inside surface that is serrated.

An electrical cable connecting system includes a modular electrical or electronic wiring device assembly, in which an electrical or electronic wiring device and a connector may be electrically coupled via pig-tail jumper electrical wires. The connector may be coupled to cable electrical wires fitted with a cable protector to protect the electrical wire conductors therein. The connector may include internal electrical terminals for electrically coupling building electrical cable wires with corresponding jumper electrical wires. The connector may be mechanically and electrically coupled to and directly terminate one or more building electrical cables, which may provide power to or from one or more electrical or electronic wiring devices by establishing an electrical pathway from a source of electrical power, through the building electrical cable wires, the connector, the pig-tail jumper electrical wires and an electrical or electronic wiring device.

A system for transmitting power and current includes a power cable having stranded wires and an exposed end. The stranded wires are ultrasonically welded together. Ultrasonically welding the wires creates a bundle of wires at the exposed end that may be free from air pockets, reducing oxidation and improving the current path through the cable.
