  2. Bi-pin lamp base - Wikipedia

    en.wikipedia.org/wiki/Bi-pin_lamp_base

    The suffix after the G indicates the pin spread; the G dates to the use of Glass for the original bulbs. GU usually also indicates that the lamp provides a mechanism for physical support by the luminaire: in some cases, each pin has a short section of larger diameter at the end (sometimes described as a "peg" rather than a "pin" [2]); the socket allows the bulb to lock into place by twisting ...

  3. Tube socket - Wikipedia

    en.wikipedia.org/wiki/Tube_socket

    The Rimlock (B8A) base is an eight-pin design with a pin circle diameter close to Noval, and uses a nub on the side of the envelope to engage with a guide and retaining spring in the socket wall. This provides pin registration (since the pins are equi-spaced) and also a fair degree of retention.

  4. Lightbulb socket - Wikipedia

    en.wikipedia.org/wiki/Lightbulb_socket

    The two-pin socket is an update of the bi-post design with smaller pins designed to reduce the cost of manufacture. The 1000-watt FEL medium two-pin base halogen lamp allows designers to insert the lamp into the end of the ellipsoidal reflector through a smaller hole than previously possible with conventional incandescent lamps. This improves ...

    en.wikipedia.org/wiki/Wedge_base

    A wedge base is a type of electrical connector used as a fitting for small light bulbs. It is similar to the bi-pin connector, except that the two "pins" are the same wires that extend into the bulb (rather

    1AY2 – 2-pin "Duopin" base High-voltage rectifier. Has similar electrical characteristics as 1B3GT. Has similar electrical characteristics as 1B3GT. 1B3GT – Octal High-voltage rectifier diode with 1.25 V filament common in monochrome TV receivers of the 1950s and early 1960s.

  7. AC power plugs and sockets: British and related types

    en.wikipedia.org/wiki/AC_power_plugs_and_sockets:...

    By the 1927 revision of BS 73 four sizes of two-pin plugs and sockets were standardized: 2 A, 5 A, 15 A and 30 A. This was later superseded by BS 372:1930 part 1 Two-pin Side-entry Wall Plugs And Sockets for Domestic Purposes. Following the introduction of BS 4573 in 1970 there were no longer any UK domestic uses for two-pin sockets except for ...

  8. DMS-59 - Wikipedia

    en.wikipedia.org/wiki/DMS-59

    A connector plug with all 60 pins (such as a Molex 88766-7610 DVI-I splitter) does not fit into a properly keyed DMS-59 socket. A Dual-DVI breakout cable can be used in connection with two passive DVI-to-HDMI adapters to feed modern displays with HDMI inputs, while using a DMS-59 graphics card, since the DVI signals are electrically identical ...

    en.wikipedia.org/wiki/Phone_connector_(audio)

    Sound cards that output 5.1 surround sound have three sockets to accommodate six channels: front left and right; surround left and right; and center and subwoofer. 6.1 and 7.1 channel sound cards from Creative Labs, however, use a single three-conductor socket (for the front speakers) and two four-conductor sockets.
