No single connector has all the ideal properties the proliferation of types is a reflection of differing requirements.įretting is a common failure mode in electrical connectors that have not been specifically designed to prevent it. In some cases an equipment manufacturer might choose a connector specifically because it is not compatible with those from other sources, allowing control of what may be connected. It is usually desirable for a connector to be easy to identify visually, rapid to assemble, require only simple tooling, and be inexpensive. connecting safety ground first, and sequencing connections properly in hot swapping applications. Some connectors are designed such that certain pins make contact before others when inserted, and break first on disconnection this protects circuits typically in connectors that apply power, e.g. They may be keyed to prevent insertion in the wrong orientation, connecting the wrong pins to each other, and have locking mechanisms to ensure that they are fully inserted and cannot work loose or fall out. Cable glands, known as cable connectors in the US, connect wires to devices mechanically rather than electrically and are distinct from quick-disconnects performing the latter.Įlectrical connectors are characterised by their pinout and physical construction, size, contact resistance, insulation between pins, ruggedness and resistance to vibration, resistance to entry of water or other contaminants, resistance to pressure, reliability, lifetime (number of connect/disconnect operations before failure), and ease of connecting and disconnecting. In computing, an electrical connector can also be known as a physical interface (compare physical layer in OSI model of networking). Connectors may join two lengths of flexible copper wire or cable, or connect a wire or cable to an electrical terminal. There are hundreds of types of electrical connectors.
An adapter can be used to effectively bring together dissimilar connectors.

The connection may be temporary, as for portable equipment, require a tool for assembly and removal, or serve as a permanent electrical joint between two wires or devices. Connectors consist of plugs (male-ended) and jacks (female-ended). An electrical connector is an electro-mechanical device for joining electrical circuits as an interface using a mechanical assembly.
