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

USB connectors are used with universal serial bus (USB) ports. They can be used to connect USB products together, or to connect USB wires and peripherals to other standard port types

Wire to wire connectors are used to connect two wire-terminated connectors

Modular connectors and RJ connectors are plug-in units used in many networking and telecommunications applications. Registered jack (RJ) connectors are a type of modular connector, which often have protective capabilities such as integrated filters to protect against unwanted signals or some type of magnetics to provide filtering, signal conditioning, and isolation

Military (MIL-SPEC) connectors are built in accordance with military specifications. Their design takes into account the need to protect the connection from environmental factors, allowing them to be used in military and aerospace applications. 

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

Micro connectors and nano connectors exhibit contact pitches of 0.05'' (micro) and 0.025'' (nano), respectively

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

Coaxial connectors are composed of an insulated central conducting wire wrapped in another cylindrical conductor (the shield). The cable is usually wrapped in another insulating layer and an outer protective layer. Coaxial cables and connectors have the capacity to carry vast quantities of information. They are typically used in high-speed data and CATV applications

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

Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and grounding protection

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

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

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
