The present invention provides an electric wire joining structure (80), an electric wire joining method, and a terminal (1), each of which allows a reduction in burden on an operator. The present invention includes: one or more electric wires (10); a terminal (1) including one or more insertion holes (7) for the respective one or more electric wires (10), the one or more electric wires (10) being inserted into the respective insertion holes (7); and a joining part (20) formed by thermal spraying, the joining part (20) joining the one or more electric wires (10) to the terminal (1) on a side on which the one or more electric wires (10) have passed through the respective one or more insertion holes (7).

An electric fence connection system includes a body formed with a slot have a predetermined depth. The slot may be formed to receive a polymer coated cable such that at least a portion of the polymer coated cable is surround by the body. The body may be formed to also include a first threaded aperture that extends through the body to the slot. A first threaded fastener may be sized to threadably engage the first threaded aperture. The first threaded fastener may include a head at a proximate end, a conical tip at a distal end and threads along a shaft of the fastener between the distal and the proximate end. The conical tip of the first threaded fastener may be formed to pierce the polymer coated cable positioned in the slot. The body may be formed with a second aperture formed to receive a power supply cable to supply electrical power to the polymer coated cable via the first threaded fastener.

Embodiments of the present disclosure relate to a terminal and a corresponding electrical component. The terminal comprises a U-shape connector comprising a first part and a second part opposite to each other, and a third part connecting the first part and the second part; a threaded terminal formed on a first surface of the first part and being integral with the first part; and an unthreaded terminal coupled to a second surface of the first part of the connector, the second surface being opposite to the first surface, and the unthreaded terminal being electrically coupled to the threaded terminal. According to embodiments of the present disclosure, actual needs of different customers can be satisfied and the reliability of the terminal can also be enhanced.

A plug connector for electrically connecting a tag connector to an electrical line of a motor-driven garden and/or forestry working apparatus includes a tag connector receptacle portion and a line receptacle portion. The tag connector receptacle portion has a first surface-clamping leg, a second surface-clamping leg, a first peripheral guiding blade and a second peripheral guiding blade, wherein the surface-clamping legs are disposed so as to be opposite one another and wherein the peripheral guiding blades are disposed so as to be opposite one another. The tag connector receptacle portion is configured for elastically enlarging a leg spacing between the surface-clamping legs and for plastically enlarging a blade spacing between the peripheral guiding blades by interaction between the peripheral guiding blades and the tag connector for receiving the tag connector and for contacting and for impinging with a clamping force opposite surfaces of the received tag connector by the surface-clamping legs, and for contacting opposite peripheries of the received tag connector by the peripheral guiding blades for securing the received tag connector against being released from the tag connector receptacle portion and for electrical contacting. The line receptacle portion is electrically connected to the tag connector receptacle portion. The line receptacle portion is configured for receiving the electrical line and for securing the received line against being released from the line receptacle portion and for electrical contacting.
