Ground for pin 9 [a] ISO 11446:2004 specifies a 13-pole electrical connector between towing and towed vehicles with 12 volt electrical system . It was developed in 1987 by Erich Jaeger [ 1 ] to replace older 7-pin plugs.
7-pin ISO 1724 trailer connector type 12N (Towing vehicle side). This connector uses a mix of pin and socket terminals. Physical design according to standard ISO 1724. [4] [8] The 7-pin connector uses all 7 pins on newer trailers according to the ISO standard. [9] [10] On older trailers there's sometimes a 5-wire setup using a 7-pin connector.
In the United Kingdom and in Ireland, this system is usually referred to simply as a "13 amp plug" or a "13 amp socket". BS 546, Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50–60 Hz) circuits up to 250 V is an older British Standard for three-pin AC power plugs and sockets.
A variety of different kinds of IEC 60320 plugs and sockets. IEC 60320 Appliance couplers for household and similar general purposes [1] is a set of standards from the International Electrotechnical Commission (IEC) specifying non-locking connectors for connecting power supply cords to electrical appliances of voltage not exceeding 250 V (a.c.) and rated current not exceeding 16 A. [1 ...
Pre-2009 T12 plug and pre-2017 T12 socket: fingers can touch dangerous voltage. Originally, T12 plugs and sockets (the most common in domestic use) posed a safety concern. As the T12 sockets are flat and as the pins of the plugs did not have any insulation, the electrical contact was established in the pins even though the latter remained ...
This diagram was created with Inkscape, or with something else. This diagram uses embedded text that can be easily translated using a text editor. This version simplified from my table:NEMA receptacle pins.svg File:NEMA receptacle pins.svg by removing the bottom row's 3-phase power plugs and IEC computer connectors, as a way to simplify the table.
Multicon [1] Feder and Multicon WeSt (Welt Standard) connectors are precursors to ISO 11446 in a design that is intended to be compatible with ISO 1724.This means that if a towing vehicle has an outlet of this type it should be able to connect a trailer with a standard 7-pin or 5-pin connector according to ISO 1724, provided that the trailer coupling follows the standard and that the trailer ...
Australasian standard three pin plug, with part insulation on the Active/Line and Neutral pins. AS/NZS 3112 is the harmonised/joint Australian and New Zealand Standard for AC power plugs (male) and sockets (female). The International Electrotechnical Commission (IEC) "world plugs" website defines this design as Plug Type I'. The plug consists ...
