A cable assembly is the composition of one or more electrical cables and their corresponding connectors.

Physical layer

physicalLayer 1PHY
In computing, electrical connectors are considered a physical interface and constitute part of the physical layer in the OSI model of networking.
The shapes and properties of the electrical connectors, the frequencies to broadcast on, the line code to use and similar low-level parameters, are specified here.

Screw terminal

A screw terminal is a type of electrical connector where a wire is held by the tightening of a screw.

Insulation-displacement connector

IDCinsulation displacementinsulation displacement connector
An insulation-displacement contact (IDC), also known as insulation-piercing contact (IPC), is an electrical connector designed to be connected to the conductor(s) of an insulated cable by a connection process which forces a selectively sharpened blade or blades through the insulation, bypassing the need to strip the conductors of insulation before connecting.

Terminal (electronics)

terminalterminalstwo-terminal
Terminal may also refer to an electrical connector at this endpoint, acting as the reusable interface to a conductor and creating a point where external circuits can be connected.

Pin header

A pin header (often abbreviated as PH, or simply header) is a form of electrical connector.

Pinout

pin-outpinoutsBallout
In addition to the classes mentioned above, connectors are characterised by their pinout, method of connection, materials, size, contact resistance, insulation, mechanical durability, ingress protection, lifetime (number of cycles), and ease of use.
In electronics, a pinout (sometimes written "pin-out") is a cross-reference between the contacts, or pins, of an electrical connector or electronic component, and their functions.

Electrical termination

terminatedterminationterminator
An electrical connector is an electromechanical device used to join electrical terminations and create an electrical circuit.
Radio frequency currents tend to reflect from discontinuities in the cable such as connectors and joints, and travel back down the cable toward the source causing interference as primary reflections.

Gold

Aunative goldgold dust
The base electrode metal is often coated with another inert metal such as gold, nickel, or tin.
Gold's high malleability, ductility, resistance to corrosion and most other chemical reactions, and conductivity of electricity have led to its continued use in corrosion resistant electrical connectors in all types of computerized devices (its chief industrial use).

USB hardware

This is in contrast to the rectangular design of some connectors, e.g. USB or blade connectors.
On-The-Go allows USB between peers without discarding the directed topology by choosing the host at connection time; it also allows one receptacle to perform double duty in space-constrained applications.

XLR connector

XLRCannon plug5-pin XLR connectors
Fields such as sound engineering and radio communication also use circular connectors, such as XLR and BNC. Plugs and sockets are widely used in various connector systems including blade connectors, breadboards, XLR connectors, car power outlets, banana connectors, and phone connectors.
The XLR connector is a style of electrical connector, primarily found on professional audio, video, and stage lighting equipment.

MIL-DTL-5015

They are widely used in military, aerospace, industrial machinery, and rail, where MIL-DTL-5015 and MIL-DTL-38999 are commonly specified.
MIL-DTL-5015 is a United States Military Standard which covers heavy-duty circular electrical connectors with soldered or crimped contacts.

Phone connector (audio)

headphone jackTRRSTRS connector
By definition, each end of this "adapter" has a different connection method – e.g. the solder tabs on a male phone connector, and the male phone connector itself. Plugs and sockets are widely used in various connector systems including blade connectors, breadboards, XLR connectors, car power outlets, banana connectors, and phone connectors.
In the US, a stationary (more fixed) electrical connector is called a jack.

Gender of connectors and fasteners

malefemalegender
Most electrical connectors have a gender – i.e. the male component, called a plug, connects to the female component, or socket.
In electrical and mechanical trades and manufacturing, each half of a pair of mating connectors or fasteners is conventionally assigned the designation male or female.

Zero insertion force

ZIFZIF socketinsertion force
They also require around 40% less insertion force – as low as 0.3 N per contact – which extends the lifespan, and in some cases offers an alternative to zero insertion force connectors.
Zero insertion force (ZIF) is a type of IC socket or electrical connector that requires very little force for insertion.

Modular connector

A modular connector is a type of electrical connector for cords and cables of electronic devices and appliances, such in computer networking, telecommunication equipment, and audio headsets.

Telephone plug

A telephone plug is a type of connector used to connect a telephone set to the telephone wiring inside a building, establishing a connection to a telephone network.

RCA connector

An RCA (Radio Corporation of America) connector, sometimes called a phono connector or (in other languages) Cinch connector, is a type of electrical connector commonly used to carry audio and video signals.

Banana connector

Plugs and sockets are widely used in various connector systems including blade connectors, breadboards, XLR connectors, car power outlets, banana connectors, and phone connectors.
A banana connector (commonly banana plug for the male, banana socket or banana jack for the female) is a single-wire (one conductor) electrical connector used for joining wires to equipment.

Crimp (electrical)

Wires may be attached to male or female blade connectors by either crimping or soldering.
An electrical crimp is a type of solderless electrical connection.

Ground (electricity)

This is often used in power connectors to protect equipment, e.g. connecting safety ground first.
An electrical connection to earth can be used as a reference potential for radio frequency signals for certain kinds of antennas.
