Connectors are devices that join two or more electronic circuits or systems together and transfer signals, data, and/or power between them. Connectors enable today's electronic systems to be interchangeable and modular.

Connectors are designed with varying configurations of pins, sockets, plugs, receptacles and other mating parts that allow them to form a secure connection to almost any device. Their metal contacts (or terminals) establish an electrical connection when mated together. Contacts can be male or female, and they align and engage when the connectors are connected.

An outer housingy-- made of plastic, metal, or a combo of the two-- typically provides mechanical support, protection, and alignment for the contacts.
Some connectors even have "locking mechanisms" like latches, screws or clips, that secure the connection and prevent accidental disconnection.
