Power connector


Power connector

A power connector is an electrical connector designed to carry a significant amount of electrical power, usually as DC or low-frequency AC. Some types of "RF connector" may also carry large amounts of power, but are considered as a separate category. Connectors carrying small amounts of power are known as "signal connectors".

Types

*AC power plugs:
**Mains power plugs, principally used for connecting equipment to wall outlets. See that article for information about mains electricity plugs around the world as well as information for travellers.
**Industrial power plugs, used for larger equipment than normal mains plugs.
*DC plugs
*Mains inlet connectors, designed to attach a power cable to an appliance, of which the IEC connector (see image below) is the most common
*Battery connectors
*Lucar or Blade connectors commonly found in cars for quick connection of wiring to electrical components
*Terminals
*Terminal blocks
*Industrial power connectors, of which one of the most common types is
**the IEC 309 (BS 4343) so-called "commando" plug and socket.
*Personal computer power supply connectors
**Molex connector — four pin hard disk drive (HDD) connectors, also used for powering CD-ROM drives, burners etc
**Berg connector — smaller four pin floppy disk drive (FDD) connectors, also used by some hard drives, and carrying the same power supplies as the HDD connectors
**AT motherboard connectors consisting of two in-line connectors
**ATX motherboard connectors which have now obsoleted the older AT-style connectors
**serial ATA (SATA) power connectors
