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.

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 connector includes a contact connected to a member to be connected and brought into contact with a wire so as to electrically connect the member to be connected and the wire. The contact includes contact portions coming into contact with the wire when the wire moves in a perpendicular direction perpendicular to a wire extending direction in which the wire extends, and movement restriction members for restricting a movement of the wire on the contact in a state where the wire is in contact with the contact portions. The contact further includes a movement regulation member for regulating a movement of the wire in the perpendicular direction in the state where the wire is in contact with the contact portions.

Shielded keystone jack structure is for connection of a plurality of wires of a first cable to be terminated to a second cable. The shielded keystone jack structure includes a front housing, terminal connection unit, wire organizer, cover, and rear housing. The front housing includes a front portion having an opening for insertion of the second cable; and an accommodation portion. The terminal connection unit has wire contacts, piercing terminals, a first guiding element, and first positioning parts. The wire organizer having wire-receiving slots for attachment of the wires thereto, as disposed on the terminal connection unit carried by the front housing, is moved towards the piercing terminals along a path at least defined by the first guiding elements and first positioning parts for termination of the wires when the cover is pivoted to a closed position. The rear housing is used for being attached to the front housing.

An insulation displacement contact comprises an electrically conductive contact body including a mounting portion that is configured to receive a complementary electrical component so as to contact an electrical terminal of the complementary electrical component, and a mating portion configured to attach to an electrical cable, the mating portion including a slot that extends into the contact body, and at least one piercing member that at least partially defines the slot such that, when the slot receives an electrical cable, the piercing member pierces an outer electrically insulative layer of the electrical cable and contacts an electrical conductor of the electrical cable that is disposed inside the electrically insulative layer.

A connector for light-emitting diode (LED) strip light is disclosed. The connector has a cavity with conductive longitudinal and transverse pins that, when the connector is assembled with an LED strip light in a cavity within the housing of the connector, penetrate the insulation of the strip light to make electrical contact with the strip light's conductors. The connector also includes gasket seals and a removable portion that exposes the cavity. The removable portion may include a window to expose any LEDs that may be within the housing of the connector.

A water blocking structure for an insulation-coated wire includes a heat-shrinkable tubular protective member that is closed at one end by a stopper and that accommodates an intermediate portion of an insulation-coated wire, and a resin material that is accommodated in the protective member and that penetrates the intermediate portion of the insulation-coated wire. Slit portions are formed in a coating of the insulation-coated wire within the protective member, the slit portions extending in a direction that crosses the axis of the insulation-coated wire on opposite sides of the intermediate portion with respect to a radial direction, and a water blocking agent penetrates the intermediate portion via these slit portions.

This disclosure relates to a piercing-type motor terminal connector, comprising a main body with a board end and a wiring end which are facing away from each other. The board end is disposed with pins for board connection, while the wiring end comprises a first elastic arm and a second elastic arm aligned side by side. A main clamping groove is formed between these arms, capable of establishing adjustable tension state based on the elasticity of the first arm and the second arm. At the groove entrance of the main clamping groove, serrations are disposed on the first and the second elastic arms. The serrations are used to press and pierce the enamel of enameled wire, allowing the wire to slide into the main clamping groove and be held by the first and the second elastic arms, thereby forming an electrical connection. Additionally, a force-enhancing part is disposed on both the first and second elastic arms, which increase the clamping force when the enameled wire enters the main clamping groove. This design enables one-time crimping and connection, making installation efficient and stable, and preventing poor electrical contact between the terminal and conductor due to vibrations.
