Connectors are the tools that act as the medium between two electrical sources. There is an input in one source and an output in the other that together form a circuit for passing the electrical current. Connector holds the wire or cable together and passes the rated current through it.

Connectors are available in different types according to the function they perform. Some connectors are for passing electric current or signal through the circuit, while some connectors are useful for data transfer purposes. Connectors are also useful in telecommunication networks. Examples are power connectors, electrical connectors, industrial connectors, audio connectors, fiber optic connectors, USB (universal serial bus) connectors and modular connectors.

Some important parameters you must consider before you buy connectors are

1. The type of application for which you require the connectors
2. The current rating which the component requires
3. The availability of standard connectors
