  2. Tightlock coupling - Wikipedia

    en.wikipedia.org/wiki/Tightlock_coupling

    The couplers automatically lock when cars are pushed together, but workers must go between cars to hook up the air lines for the pneumatic brakes and connect cables for head-end power and other communications. To separate cars, a worker must use a lever to move the locking pin that keeps the coupler closed.

    Plus in newer cars, the power output from the lighter plug is so reliable that it can charge laptops, without any voltage problems. Standardized 12 volt DC automobile plugs are defined in the United States by UL Standard 2089 regarding vehicle battery adapters. This standard covers plugs and cord sets that insert into cigarette lighter receptacles.

    The NP/NV-231 case is a chain-driven unit that takes 21- or 23-spline input shafts. The 23-spline was for the AX-15 transmission, and the 21-spline was used for the AX-5 and BA 10/5 transmissions. Low range for this case was 2.72 and high range was 1.00. The Command-Trac HD transfer case was used in 6-speed Liberty KJ's from 2005 to 2007.

    Since 2019, Tesla has adopted the CCS2 connector on their Version 3 Superchargers (outputting 250 kW), including a second cable for CCS support on Version 2 Superchargers, on all European models of the Model 3 and Y, with a hardware upgrade and adapter for pre-2019 Model S and X vehicles, [3] and since 2022 on Model S and X as the new connector ...

  6. BNC connector - Wikipedia

    en.wikipedia.org/wiki/BNC_connector

    It has a twist-to-lock design, where two lugs on the female connector engage slots in the shell of the male one. BNC is designed to maintain the characteristic impedance of the cable across the connection, and is made in 50-ohm and 75-ohm versions. It is normally used for radio-frequency signals up to about 2 gigahertz and 500 volts.

    The waveform of 230 V and 50 Hz compared with 120 V and 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.

  9. Railway coupling - Wikipedia
