An electric motor built for exposure to high pressure fluid includes a unitary metal sleeve that provides a fluid barrier between the rotor and the stator. An overmolded resin encapsulates the stator windings and reinforces the sleeve to minimize deformation of the sleeve under high fluid pressures. The overmolded resin also fixes the positions of insulation displacement connectors connected to the stator windings, thereby avoiding mechanical brackets and fasteners for holding the insulation displacement connectors in position.

A connection instrument includes: a cable including an electrical wire and two separated covering parts covering the electrical wire; a connection terminal connectable to a terminal of an external connector; a connection part; a flat plate-shaped wiring board; and a housing. The connection part electrically connects the connection terminal and the electrical wire exposed between the two separated covering parts. The connection terminal and connection part are arranged on the wiring board. The wiring board is located between the two covering parts. The housing allows insertion/extraction of the external connector and houses the wiring board. At least part of the wiring board is roughly in contact with or included in a space linking adjacent ends of the two covering parts.

A conductive terminal comprises a body and a pair of first elastic cantilevers adapted to clamp a first conductor. The pair of first elastic cantilevers are connected to the body and accommodated within a first accommodation chamber formed in the body. Each first elastic cantilever or the body has a first elastic support structure. A free end of each first elastic cantilever is elastically supported on an inner wall of the first accommodation chamber by the first elastic support structure when the first conductor is clamped between the pair of first elastic cantilevers.

A contact member for an insulation displacement contact (IDC) terminal includes an encasement wall at least partially surrounding a receptacle volume receiving a wire or cable, an IDC member having an IDC blade penetrating an insulation of the wire or cable and a contact edge electrically contacting a core of the wire or cable, and a cutting blade cutting the wire or cable. The receptacle volume has an opening at least partially framed by the encasement wall. The IDC member is formed in a first wall section of the encasement wall. The cutting blade is formed in a second wall section of the encasement wall opposite the first wall section. Both the IDC blade and the cutting blade face the opening.

A stator for an electric motor, connected to a circuit board, comprising a stator housing in which several winding arrangements consisting of winding wires wound to form coils are arranged. Contact support receptacles are formed on the stator housing, in which, in each case, an insulation displacement contact element is introduced, which establishes an electrical contact between, in each case, a winding arrangement and a jumper wire on the circuit board.

A terminal is to be connected to an electric wire including a conductor core wire and a sheath covering the conductor core wire. The terminal includes a connection portion and a conductor fixing portion which is located rearward of the connecting portion and configured to fix the conductor core wire exposed from the electric wire. The connection portion and the conductor fixing portion are integrally formed to each other and are extended in a front-rear direction. The conductor fixing portion has through holes penetrating in a thickness direction of the conductor fixing portion. An end edge portion of each of the plurality of through holes on an outer peripheral surface side of the conductor fixing portion is provided with a tapered portion that increases in diameter of the tapered portion toward an outer peripheral surface of the conductor fixing portion.
