BITUO manufacturer of Audio Plugs and Jacks as per International Standards with Moulding Wire Availability of all Size Range.
2.1 mm Barrel Plug (for one common type of connector) is an electrical connector for supplying direct current (DC) power to the grid.
Small cylindrical connectors come in a variety of sizes. They may be known as “coaxial power connectors”, “barrel connectors”, “concentric barrel connectors” or “tip connectors”.
The intended use of these plugs is on the cable connected to an external AC adapter (power supply). The matching jack or socket is permanently fitted to the equipment to be powered. Some of these jacks contain a normally closed contact, which can be used to disconnect internal batteries whenever the power supply is connected, avoiding the risk of battery leakage or explosion posed by incorrect recharging of the batteries.
Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable. The dimensions and arrangement of DC connectors can be chosen to prevent accidental interconnection of incompatible sources and loads. Types vary from small coaxial connectors used to power portable electronic devices from AC adapters, to connectors used for automotive accessories and for battery packs in portable equipment.
Miniature plugs suitable for powering portable radios, calculators plus test and measurement instruments from a fixed, low-voltage D.C. source. Chassis mounting sockets for the 2.1mm plugs and adaptor leads terminated with 2.1mm, 2.5mm, 6.35mm plugs and sockets are also available. Contacts are nickel/silver plated brass. Connector bodies are moulded in steel or ABS plastic. Contact BITUO for 2.1 mm Barrel Plug today!
