What is an electronic connector?

Electrical circuits are made up of an array of components, including wires and cables. Electrical connectors are utilized to join these to create a continuous path for electrical current to flow. Connectors have plugs and jacks that connect to each other, creating either a permanent connection or, more frequently, a temporary connection that can be assembled and removed with special tools.

Connectors play an essential role in electronics equipment and projects. Using the right connector for the correct application is vital. Its importance goes beyond just safety; it is also necessary for PCB and product manufacturing to create efficient and cost-effective products. They drastically reduce the time, effort, and manpower required for producing, assembling, and installing electrical devices, their components, and wiring. Consequently, manufacturers have created a wide variety of unique electronics connectors designed to fit a particular application or product. Some connectors are very versatile; they are used in almost all electronic products we use every day. 



Most connectors contain two principal components– the housing and terminals for making the connections: The housing is the structure utilized to contain the terminals, protect the electrical contacts from short-circuiting and external hazards and guarantee the stability of the connections. They are usually made from molded plastic and other insulating materials. On the other hand, The terminals are the pins in a connector that provides electrical conduction to secure connections.

Different electrical connectors are required for some applications:

Keyed Connectors

This type of connector is designed to connect only when it is in the proper orientation. This helps prevent accidental damage to the pins and stops users from inserting them into the wrong sockets.

Locked Connectors

A locking mechanism guarantees the connectors are kept in place, stopping connections from breaking unexpectedly or shifting when the connector is bumped or jolted.

Hermetically Sealed Connectors

Some applications need an electrical connection that might be immersed in water. These connectors are purpose-built to be entirely operating underwater and resist pressure up to specific depths.

Water Resistant Connectors

While they normally can’t endure being immersed, this type of connector protects the electrical connections against water damage from splashes or occasional dampness. 

Moisture Resistant Connectors

These are intended to preserve the electrical connections from damage caused by oil or moisture.

Electromagnetic interference or RFI Filtering

Additional features built into the housing to protect the connectors from EMI or radio frequency interference that damage circuits carrying electrical signals.

ESD Shielded Connectors

Electrostatic discharge can destroy wiring and components. This type of connector provides additional protection against this.



Some aspects should be considered when choosing the appropriate electrical connectors. Depending on the application, kind of connectors, and the electrical current’s strength, the circuit will carry. These can be divided into two classifications:

  • Performance Parameters:

    Performance parameters have to be chosen based on the conditions in which the electrical connector is going to work- these include current, voltage, and Operating Temperature.

  • Physical Parameters:

    Physical parameters should be chosen carefully as they describe how the electrical connector is designed, the connections it can be used for, and more factors.
