According to the present invention, an additional component circuit body, the structure of which changes in accordance with the type of vehicle or options, and a first base circuit body, the structure of which is fixed, are produced separately, and a whole circuit is configured by combining said circuit bodies. The additional component circuit body has a backbone structure, which is configured such that various branch lines can be attached/detached thereto/therefrom, and a branch line. A main line and the branch line include a power supply line and a communication line. The additional component circuit body has a superordinate control unit and subordinate control unit that control the power supplied to an electrical component that is connected to each branch line. The invention has a switching circuit for switching the connection state of each terminal. Supplied power is controlled by switching the terminals to which power is supplied.

A flat electrical cable is described. The cable includes a plurality of equally spaced substantially parallel electrical conductors lying in a same plane and extending along the length of the cable. Each conductor has a same diameter D. The cable further includes a common unitary electrically insulating layer encapsulating the plurality of conductors. The insulating layer includes a plurality of cover portions where each cover portion is concentric with a corresponding conductor and has a radial thickness t. t/D is in a range from about 0.50 to about 1.25.

A safe grounding apparatus (SGA) for safely grounding or neutralizing the electrical conductors for permanent magnet motor (PMM) powered artificial lift systems and methods of practicing the same are disclosed. The SGA of the present invention ameliorates some of the dangers associated with PMM's. Methods of shorting, grounding, testing and monitoring the electrical conductors of a permanent magnet motor in order to safely manipulate the conductors are also disclosed.

A cable connection device includes a first shell, a plurality of conducting terminals mounted on the first shell, and a second shell covering the first shell. The first shell includes a main portion provided with a receiving recess and a restriction portion provided with a plurality of mounting spaces. The conducting terminals extend into the mounting spaces respectively. The second shell is provided with a plurality of press blocks. When the conducting wires of each of the two cables extend to the conducting terminals, the press blocks extend into the mounting spaces and press the conducting wires of each of the two cables, with the conducting terminals piercing the conducting wires of the two cables simultaneously, to connect and electrically conduct the conducting wires of the two cables by the conducting terminals.

A connector includes a cable tray configured to receive and retain a cable in a stable position and couple with a top cap configured to create an electrical connection with the cable as the top cap is manipulated in a predetermined manner while coupled with the cable tray. An upper surface of the cable tray is configured to receive the cable (e.g., while the cable is generally parallel with the longitudinal axis of the cable tray). The cable tray also includes a finger extending beyond the first end for some distance longitudinally. The finger includes a protrusion that protrudes to some extent in a transverse direction so that a cable-accommodating gap is defined between the protrusion and the first end. The protrusion is configured to bear against the cable and retain the cable in the stable position when the cable is inserted between the protrusion and the first end (before, during and/or after an electrical connection is established).

A connector for installation on a printed circuit board a contacting part has which includes at least two contact elements, each of which can be connected, on the connection side, to an individual conductor and, on the plug-in side, to a conductive track of the printed circuit board, wherein the connector a connection part which encloses the individual conductors and, in the region of each individual conductor, has a recess, into each of which a contact element engages for the electrical connection between individual conductor and contact element. The contacting part is formed in an injection molding process, wherein at least two contact elements having an insulation-displacement connector are inserted or engaged in the contacting part or are directly encapsulated, and the connection part is formed in an injection molding process, wherein at least two individual conductors, each having a cable sheath, are thus placed in an injection molding tool and are encapsulated.

A communication connector includes a housing defining a plug receiving space with a circuit board arrangement supported by the housing, which has pairs of communication paths associated with a plurality of contact pads. A spring contact arrangement includes a support/guide and a spring contacts. Each spring contact has a supported/guided portion, an extending end, an intervening pad contact portion contacting a pad, between the supported/guided portion and the extending end, a spring arm portion between the supported/guided portion and the pad contact portion and having a contact portion, with a plug contact surface, between the pad contact portion and the extending end. The plug contact surface is positioned in the plug receiving space in an unmated state. In plug mated state a deflection of the contact portion causes a relative deflection of the spring arm portion.

An electrical connector for transmitting data signals between the insulated conductors of a first data cable and corresponding insulated conductors of a second data cable, including a first part having a socket shaped to at least partially receive a plug of said first data cable; a second part having a plurality of insulation displacement contact slots shaped to receive end sections of the conductors of the second data cable; and a plurality of electrically conductive contacts including resiliently compressible spring finger contacts extending into the socket for electrical connection with corresponding conductors of the first cable; insulation displacement contacts seated in corresponding insulation displacement contact slots for effecting electrical connection with corresponding conductors of the second data cable; and mid sections extending therebetween, wherein relative movement between the mid sections of the contacts is inhibited by a fastener.
