Electrical connectors are devices that join electrical circuits together. Male connectors plug into receptacles, jacks, and outlets. Female connectors contain sockets to receive other devices

DC power supplies accept an input power and output the desired form of DC power. Common types of DC power supplies include linear power supplies, switching power supplies, DC-DC converters, and silicon controlled rectifier (SCR) type power supplies

AC power connectors transfer alternating current through a variety of electronic devices. AC power connectors include simple AC inlets, outlets, and power entry modules

Power connectors transfer AC or DC through a variety of electronic devices and are used in a variety of commercial, industrial, and residential applications. Power connectors range from simple AC or DC inlets and outlets to sophisticated power entry modules

Circular connectors are multi-pin connectors primarily used for external interfacing

Instrument and computer (disk drive) power connectors are available in two basic styles. The larger size, often called a Molex connector, is keyed and used on most internal drives. The smaller size, a mini-plug, is used for newer style disk drives

DIN connectors are high frequency, multi-pin, electrical connectors that meet standards established by Deutsches Institut für Normung (DIN), a German national organization for standardization. The ends of DIN connectors are round, notched, and protected by a metal skirt to ensure that pins line up correctly

Edge card connectors are edge-on connectors designed for single-sided or double-sided printed circuit boards (PCBs

Computer board and card edge connectors are used inside personal computers to connect disk drives, CD drives, and serial and parallel ports to the motherboard

D-subminiature or D-sub connectors are sturdy electrical connectors with a mating face shaped like the letter D. They provide polarization because male and female connectors can fit together in only one way

Computer power supplies convert alternating current (AC) line to direct current (DC) line, needed by the computer

Heavy duty rectangular connectors are designed to accommodate large electrical loads and direct signals under a multitude of operating conditions

PC card connectors are used to connect computer cards to computers. Examples include PC cards and CompactFlash cards

Single phase uninterruptible power supplies (UPS) sit between an AC outlet (i.e., a wall outlet or power strip) and an electronic device (e.g., computer, server, or phone equipment) to provide power conditioning, back-up protection and distribution for electronic equipment loads

IEEE 1394 connectors are used to connect FireWire^® devices such as host controllers, adapters, hard drives, hubs, repeaters, and card readers. FireWire, a registered trademark of Apple Computer, is a communications protocol for the transmission of data, video, and audio over a single cable at very high bit rates
