Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket. Thousands of configurations of connectors are manufactured for power, data, and audiovisual applications. [3] Electrical connectors can be divided into four basic categories, differentiated by their function: [4]
Gender of connectors and fasteners; AC power plugs and sockets, devices that allow electrically operated equipment to be connected to the primary alternating current power supply in a building; RF connector, an electrical connector designed to work at radio frequencies in the multi-megahertz range; Circular connector; Cigarette lighter receptacle
Twist-on wire connectors are available in a variety of sizes and shapes. While their exterior covering is typically made from insulating plastic, their means of connection is a tapered coiled metal insert, which threads onto the wires and holds them securely.
The same usage also generally occurs in Italy, where the English word jack is commonly used to indicate the connector on the end of a headphone lead. [citation needed] In Romania, female connectors are known as mamă ("mother") and male connectors are tată ("father"). [citation needed]
The connectors the USB committee specifies support a number of USB's underlying goals, and reflect lessons learned from the many connectors the computer industry has used.

The first types of small modular telephone connectors were created by AT&T in the mid-1960s for the plug-in handset and line cords of the Trimline telephone. [1] Driven by demand for multiple sets in residences with various lengths of cords, the Bell System introduced customer-connectable part kits and telephones, sold through PhoneCenter stores in the early 1970s.

The other connectors with the same pin spacing are the DA-26, DB-44, DC-62, DD-78 and 104-pin. They all have three rows of pins, except the DD-78 which has four, and the 104-pin which has five rows. [1] The double density series of D-sub connectors features even denser arrangements and consists of the DE-19, DA-31, DB-52, DC-79, and DD-100 ...
Compression connectors on an isolating valve; the reddish part is a copper compression ring Compression fittings (sometimes called "lock-bush fittings") consist of a tapered, concave conical seat; a hollow, barrel-shaped compression ring (sometimes called a ferrule); and a compression nut which is threaded onto the body of the fitting and ...
