Molex connector is the vernacular term for a two-piece pin and socket interconnection, most frequently disk drive connectors. Pioneered by Molex Connector Company, the two-piece design became an early electronic standard. Molex developed and patented the first examples of this connector style in the late 1950s and early 1960s.〔Krehbiel, John H., "Wire Connector" (US 3178673 ), issued April 1965〕〔Krehbiel, John H., "Electrical Connector Having Resilient Accurately Bendable Locking Means", (US 3409858 ), issued November 1968〕 First used in home appliances, other industries soon began designing it into their products from automobiles to vending machines to mini-computers. In such a connector, cylindrical spring-metal pins fit into cylindrical spring-metal sockets. The pins and sockets are held in a rectangular matrix in a nylon shell. The connector typically has two to 24 contacts and is polarized or keyed to ensure correct orientation. Pins and sockets can be arranged in any combination in a single housing, and each housing can be either male or female. There are three typical pin sizes: , , and . The 1.57 mm pin can carry 5 A of current, while the 2.36 mm can carry 8.5 A. Because the pins have a large contact surface area and fit tightly, these connectors are typically used for power. In October 1963 AMP (now a division of Tyco International) introduced the ''MATE-N-LOK'' connector.〔United States Patent and Trademark Office, Word Mark MATE-N-LOK for Electrical Connectors first used in commerce Oct 18, 1963, Serial Number 72179683, Filing Date October 24, 1963, Registration Number 0786321, Registration Date March 9, 1965, Owner AMP INCORPORATED〕 The AMP connector was similar to the patented Molex connectors but not interchangeable. Both were widely used in the computer industry and the term "Molex Connector" is often used to refer to all nylon plugs and receptacles. The first 5.25 inch floppy disk drive, the Shugart SA400, introduced in August 1976 used the AMP MATE-N-LOK connector part number 350211-1. This connector became the standard for 5.25 inch format peripherals such as hard drives and was used until introduction of SATA drives. In 1983, Molex introduced the 8981 connector that was fully compatible with the AMP MATE-N-LOK connector. ==Desktop PC use== Several connector types have become established for connecting power in desktop PCs, because of the simplicity, reliability, flexibility, and low cost of the Molex design. Certain Molex connectors are used for providing power to the motherboard, fans, floppy disk drive, CD/DVD drive, video card, some older hard drive models, and more. Compatible connectors are available from many manufacturers, not just Molex and AMP. 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「Molex connector」の詳細全文を読む スポンサード リンク
