E12BB Application Field and Working Principle

E12BB is the abbreviation of the French term, Entretoises 12 points, Barrière Barrel (12-point spacer, Barrier Barrel). It is a kind of audio connector which is distinguished by its gold-plated contact pins and insulated housing. It is widely used in automotive, electrical and electronic, manufacturing, audio equipment, medical equipment, and more.

The E12BB connector consists of two main parts: the pin barrel and the insulation sleeve. The pin barrel is equipped with three or four parallel pins arranged in a straight line. Each pin is surrounded by an insulation ring made of plastic material which can withstand up to 150 degree Celsius. The insulation sleeve is composed of a metal body with a rubber seal on the inner side and it can provide extra protection from dust, moisture, and other factors. The external side is equipped with fold-down strain reliefs to protect the cables from the mechanical stress.

The working principle of an E12BB connector is quite simple. When connecting the two sides of the connector, the pins of the pin barrel will make electrical contact with the corresponding contacts on the other side. The insulation sleeve will help to prevent any unwanted electric sparks and ensure a proper electric connection. As the pin barrel is gold-plated, it will make a good electric connection even after a long time of repeated insertions and withdrawals.

E12BB connectors are often used in audio signal transmission, video signal transmission, USB signal transmission, communication equipment, and other industrial electronics. In automotive applications, it can be used to connect various instrumentation, such as gauges, alarms, and more. In medical equipment, these connectors can be used to transmit signals from the medical device to the display in order to monitor the patient\'s health. It can also be used in different power supplies, allowing the connection of appliances and other power-consuming devices.

With the development of technology, the use of E12BB connectors has been greatly extended. It can be used as a reliable connection in a wide variety of applications. Moreover, its strong insulation sleeve and the gold-plated contact pins guarantee a long service life even in severe environment. All these make it become one of the most popular audio connectors.
