Electrical circuits are composed of a multitude of components, including wires and cables. Electrical connectors  are used to join these to form a continuous path for electrical current to flow. Terminal connector have male-ends (plugs) and female-ends (jacks) which connect to each other forming either a permanent connection or, more often, a temporary connection that can be assembled and removed with special tools. The main content of this paper is about the features of the electrical connector.

Composition

Most wire connectors have two main parts – the housing, and terminals for making the connections:

• Housing – The housing is the structure or case used to contain the terminals, ensure  stability of the connections and protect the electrical contacts from short-circuiting and environmental hazards. Connector housings are  normally made of molded plastic, but other insulating materials like  ceramics are also used.

• Terminals – Terminals are the pins in a connector which provide electrical conduction  to make the connections secure. They are almost always composed of a  metal, but some of them use other conductive materials (carbon, silicon, etc.).

Features/Properties

For some applications, electrical connectors that possess different features might be required or preferred:

• Keyed Connectors – These are designed to connect only when they are in the proper orientation. This  prevents accidental damage to the pins and prevents users from inserting them in the wrong sockets.

• Locked Connectors – A  locking mechanism ensures the connectors are held in place, preventing  connections from breaking accidentally, or from shifting when the connector is bumped or jolted.

• Hermetically Sealed Connectors – Some applications require an electrical connection which  might be submerged in water. These connectors are purpose built to be fully functioning under water and withstand pressure up to certain depths.

• Water Resistant Connectors – While they usually can’t withstand being submerged, these  connectors provide protection for the electrical connections against water  damage from splashes or occasional dampness.

• Moisture/Oil Resistant Connectors – These are designed to protect the electrical connections from damage caused by oil or moisture.

• EMI or RFI Filtering – Additional features built into the housing top protect the connectors from  electromagnetic interference (EMI) or radio frequency interference (RFI),  which can affect circuits carrying electrical signals.

• ESD Shielded Connectors – Electrostatic discharge can damage wiring and components. ESD shielded connectors provide additional protection against this.

Electrical connectors drastically reduce the time, effort and manpower needed for manufacturing, assembling and installing electrical devices, their components as well as wiring.

Different electronic connectors have different functions, and we need to choose the right electronic connector according to different needs.
