  2. Circuit diagram - Wikipedia

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.

    PJ-055 (top) and PJ-068 (bottom) General Aviation Audio Phone Connectors "NATO" plug type, commonly used on military aircraft and civil helicopters. The following electrical connectors are commonly used in aviation headsets: [1]

  4. NEMA connector - Wikipedia

    en.wikipedia.org/wiki/NEMA_connector

    Cheater plug adapters allow a "3-prong" grounded 5-15P plug to be mated to a non-grounded 1-15R receptacle. The adapters include a spade lug to allow connecting to ground, often via the cover screw used to attach the outlet faceplate. These adapters are illegal in some jurisdictions, in particular throughout Canada. [14]

    The adapter typically supplies power to the device through a thin electrical cord which terminates in a coaxial power connector often referred to as a "barrel plug" (so-named because of its cylindrical shape). The polarity of the adapter cord and plug must match the polarity of the device, meaning that the positive contact of the plug must mate ...

  7. Kinematic diagram - Wikipedia

    en.wikipedia.org/wiki/Kinematic_diagram

    In mechanical engineering, a kinematic diagram or kinematic scheme (also called a joint map or skeleton diagram) illustrates the connectivity of links and joints of a mechanism or machine rather than the dimensions or shape of the parts. Often links are presented as geometric objects, such as lines, triangles or squares, that support schematic ...

    Although the plug is female, with a partially recessed center contact, it is still possible for casual accidental contact with a metallic object to short-circuit the power source. Depending on the design of the power adapter, it may react to a short circuit by shutting down temporarily, or instead by blowing out an internal safety fuse.

  9. Reversing gear - Wikipedia

    en.wikipedia.org/wiki/Reversing_gear

    It is controlled by a handle and sprung trigger at the top, and pivots at the bottom to pass between two notched sector plates. The reversing rod, which connects to the valve gear, is attached to the lever either above or below the pivot in an alignment that gives good leverage. A square pin is arranged to engage with notches cut in the plates ...
