  2. Electrical contact - Wikipedia

    en.wikipedia.org/wiki/Electrical_contact

    Form D contacts ("continuity transfer" contacts) differ from Form C in only one regard, the make-break order during transition. Where Form C guarantees that, briefly, both connections are open, Form D guarantees that, briefly, all three terminals will be connected. This is a relatively uncommon configuration.

  3. Terminal (electronics) - Wikipedia

    en.wikipedia.org/wiki/Terminal_(electronics)

    Terminal symbol A terminal strip, to which wires can be soldered. A terminal is the point at which a conductor from a component, device or network comes to an end. [1] Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.

  4. Electric wire ferrule - Wikipedia

    en.wikipedia.org/wiki/Electric_wire_ferrule

    Top: wire terminating in an insulated ferrule Center: Several ferrules with colored insulation, and two uninsulated ferrules Insulated, and uninsulated ferrules. An electric wire ferrule (sometimes electric end terminal) is a metal tube crimped over stranded wire to secure the strands within a screw terminal. Electrical insulation may be ...

  5. Main distribution frame - Wikipedia

    en.wikipedia.org/wiki/Main_distribution_frame

    The MDF is a termination point within the local telephone exchange where exchange equipment and terminations of local loops are connected by jumper wires at the MDF. All cable copper pairs supplying services through user telephone lines are terminated at the MDF and distributed through the MDF to equipment within the local exchange e.g. repeaters and DSLAM.

  6. Port (circuit theory) - Wikipedia

    en.wikipedia.org/wiki/Port_(circuit_theory)

    In electrical circuit theory, a port is a pair of terminals connecting an electrical network or circuit to an external circuit, as a point of entry or exit for electrical energy. A port consists of two nodes (terminals) connected to an outside circuit which meets the port condition – the currents flowing into the two nodes must be equal and ...

  7. Passive sign convention - Wikipedia

    en.wikipedia.org/wiki/Passive_sign_convention

    Illustration of the "reference directions" of the current (), voltage (), and power () variables used in the passive sign convention.If positive current is defined as flowing into the device terminal which is defined to be positive voltage, then positive power (big arrow) given by the equation = represents electric power flowing into the device, and negative power represents power flowing out.

  8. Electrical termination - Wikipedia

    en.wikipedia.org/wiki/Electrical_termination

    At the two ends of the bus, resistors connect between the positive (high) and negative (low) signal wires either in internally terminated bus couplers or external connectorized terminators. The MIL-STD-1553B bus must be terminated at both ends to minimize the effects of signal reflections that can cause waveform distortion and disruption or ...

  9. Reflections of signals on conducting lines - Wikipedia

    en.wikipedia.org/wiki/Reflections_of_signals_on...

    A time-domain reflectometer; an instrument used to locate the position of faults on lines from the time taken for a reflected wave to return from the discontinuity.. A signal travelling along an electrical transmission line will be partly, or wholly, reflected back in the opposite direction when the travelling signal encounters a discontinuity in the characteristic impedance of the line, or if ...
