A core wire connecting body to be connected to a core wire in an electric wire includes: a bottom, a pair of cantilevered side walls that are disposed facing each other with a space therebetween; and a plurality of pairs of press contact bodies that are disposed facing each other with a space between the pair of side walls, and that cut the coating of the electric wire inserted from an opening, and make press contact with the strands. For the pairs of press contact bodies, compared to a distance between the press contact bodies that is a pair at the farthest section that is farthest from an end part of the electric wire, a distance between the press contact bodies that is a pair closer to the end part of the electric wire than the pair at the farthest section are, is smaller.

An insulation displacement contact is for piercing through an insulation of a cable or wire in a cutting direction and electrically contacting an electrically conductive core of the cable or wire. The insulation displacement contact includes a contact body having a piercing section for piercing the insulation and a contact slot receiving the core of the cable or wire. The contact slot extends along the cutting direction from the piercing section into the contact body. The contact body has a pair of blades separated by the contact slot. The blades have a pair of attachment slots extending from the piercing section into the blades.

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.

A lighting apparatus includes a wire connector, a driver and a light source. The wire connector is used for connecting an external wire and an internal wire. The external wire includes a first external sub-wire and a second external sub-wire. The internal wire includes a first internal sub-wire and a second sub-wire. The wire connector has a scraper for cutting contact parts of the internal wire and the external wire for the first external sub-wire to be electrically connected to the first internal sub-wire and the second external sub-wire to be electrically connected to the second internal sub-wire. The driver is used for connecting to an external power via the internal wire and the external wire and for converting the external power to a driving current. The light source receives the driving current to emit a light.

A terminal for connecting an electrical conductor with a sheath includes: a first side wall section and a second side wall section, which are arranged opposite one another and/or spaced apart from one another. The first side wall section has a first terminal element and the second side wall section has a second terminal element which are assigned to one another to form a terminal slot and are arranged at least sectionally at a distance from one another. The first side wall section has a cutout in its end face, at which the electrical conductor is guided on the terminal slot for connection to the terminal, which cutout is groove-shaped to at least sectionally receive in the cutout a tool placed on the terminal in a form-fitting manner.

An electric motor includes a rotor and a stator including a stator core and coils. The coils are defined by a winding wire including winding wire ends electrically contacted with a printed circuit board at an end surface through connectors. The connectors each include at least two insulation displacement contacts receiving a winding wire end of a stator winding. Each connector includes a single electrical connection to the printed circuit board. The connector includes a base body with an underside in contact with the printed circuit board. Each of the at least two insulation displacement contacts includes a clamping slot perpendicular to the underside of the base body. The clamping slots are defined by spaced legs extending from the base body, at least two of the spaced legs being resilient.

Aspects of the present disclosure relate to an electrical connection device having features for cutting an electrical power conductor while maintaining downstream continuity and limiting access to the electrical power conductor.
