A DIN connector is an electrical connector that was originally standardized by the ''ドイツ語:Deutsches Institut für Normung'' (DIN), the German national standards organization. There are DIN standards for a large number of different connectors, therefore the term "DIN connector" alone does not unambiguously identify any particular type of connector unless the document number of the relevant DIN standard is added (e.g., "DIN 41524 connector"). Some DIN connector standards are: * DIN 41524, for circular connectors often used for audio signals * DIN 41612, rectangular connectors used to connect plug-in cards to a back plane or motherboard * DIN 41652 D-subminiature connectors used for computer data and video In the context of consumer electronics, the term "DIN connector" commonly refers to a member of a family of circular connectors that were initially standardized by DIN for analog audio signals. Some of these connectors have also been used in analog video applications, for power connections and for digital interfaces such as MIDI or the IBM AT computer keyboard (later PS/2 connectors for keyboard and mouse are Mini-DIN connectors). The original DIN standards for these connectors are no longer in print and have been replaced with the equivalent international standard IEC 60130-9. While DIN connectors appear superficially similar to the newer professional XLR connectors, they are not compatible. == Circular connectors == All male connectors (plugs) of this family of connectors feature a 13.2 mm diameter metal shield with a notch that limits the orientation in which plug and socket can mate. A range of connectors of the same form that differ only in their pin configuration exist and have been standardized originally in DIN 41524 / IEC/DIN EN 60130-9 (3-pin at 90° and 5-pin at 45°), DIN 45322 (5-pin and 6-pin at 60°), DIN 45323 (6-pin), DIN 45329/IEC 10 (7-pin at 45°), DIN 45326 / IEC/DIN EN 60130-9 (8-pin at 45°), and other standards for a range of different applications, including the following examples: The plugs consist of a circular shielding metal skirt protecting a number of straight round pins. The pins are 1.45 mm in diameter and equally spaced (at 90°, 72°, 60° or 45° angles) in a 7.0 mm diameter circle. The skirt is keyed to ensure that the plug is inserted with the correct orientation, and to prevent damage to the pins. The basic design also ensures that the shielding is connected between socket and plug prior to any signal path connection being made. However, as the keying is consistent across all connectors, it does not prevent incompatible connectors from mating, which can lead to damage; this is changed in Mini-DIN, which keys different connectors. There are seven common patterns, with any number of pins from three to eight. Three different five-pin connectors exist, known as 180°, 240°, and 270° after the angle of the arc swept between the first and last pin (see figures above). There are also two variations of the six-pin, seven-pin and eight-pin connectors, one where the outer pins form 360° and one where they form 270°. There is some limited compatibility, for example a three-pin connector will fit any 180° five-pin socket, engaging three of the pins and leaving the other two unconnected, a 180° five-pin plug will fit into a seven- or eight-pin socket. 3-pin and 180° 5-pin connectors will also fit the 270° 7-pin and both 8-pin sockets. In addition to these connectors, there are also connectors with 10, 12 and 14 pins. Some high-range equipment used seven-pin connectors where the outer two carried digital system data:〔(【引用サイトリンク】 title=Sounds Heavenly - Help and Advice )〕 if the connected equipment was incompatible, the outer two pins could be unscrewed from plugs so that they fitted into standard five-pin 180° sockets without data connections. Screw-locking versions of this connector have also been used in instrumentation, process control and professional audio.〔IEC 60268-11〕 In North America this variant is often called a "small Tuchel" connector after one of the major manufacturers. Tuchel is now a division of Amphenol. The pin and socket inserts are nearly identical to those used in non-locking connectors, and in some cases locking and non-locking connectors can be mated. Additional configurations up to 24 pins are also offered in the same shell size. A bayonet-locking version was also used on portable tape recorders and dictation machines through the 1980s, an example of this where found from sixties to eighties in the "Report" family of UHER tape recorders, which microphone input connector was fitted with bayonet locking instead of the standard screw. In addition to this, the input pin of such a connector are inverted with respect to DIN standards. Some manufacturers offered panel-mounted jacks with potential-free auxiliary contacts that would open if a plug were inserted. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DIN connector」の詳細全文を読む スポンサード リンク
