  2. Tube socket - Wikipedia

    en.wikipedia.org/wiki/Tube_socket

    An early transistor socket and an integrated circuit socket are included for comparison. Tube sockets are electrical sockets into which vacuum tubes (electronic valves) can be plugged, holding them in place and providing terminals, which can be soldered into the circuit, for each of the pins. Sockets are designed to allow tubes to be inserted ...

  3. Automobile auxiliary power outlet - Wikipedia

    en.wikipedia.org/wiki/Automobile_auxiliary_power...

    The outlet is connected directly to the electrical system of the car. The actual voltage, matching the car battery's voltage, will be approximately 12.5 volts when dormant (less in cold conditions), approximately 14.5 volts when the engine and the alternator/generator are operating (more when cold), and may briefly drop as low as 5–6 volts ...

  4. Battery holder - Wikipedia

    en.wikipedia.org/wiki/Battery_holder

    A battery holder is one or more compartments or chambers for holding a battery. For dry cells, the holder must also make electrical contact with the battery terminals. For wet cells, cables are often connected to the battery terminals, as is found in automobiles or emergency lighting equipment.

  5. Battery terminal - Wikipedia

    en.wikipedia.org/wiki/Battery_terminal

    Automotive batteries typically have one of three types of terminals.. In recent years, the most common design was the SAE Post, consisting of two lead posts in the shape of truncated cones, positioned on the top of the battery, with slightly different diameters to ensure correct electrical polarity.

  9. Electric vehicle battery - Wikipedia

    en.wikipedia.org/wiki/Electric_vehicle_battery

    The charging power can be connected to the car in two ways. The first is a direct electrical connection known as conductive coupling. This might be as simple as a mains lead into a weatherproof socket through special high capacity cables with connectors to protect the user from high voltages.
