Rectangular connectors are used in a wide variety of applications, ranging from automotive and industrial electronics to consumer electronics. The 71991-820LF connector is a type of rectangular connector that is used in many applications and can be found in a variety of shapes and sizes, from miniature to large. This article will explain the application field and working principle of the 71991-820LF connector.
Application Field
The 71991-820LF connector is mainly used in applications that require high frequency data transmission. These connectors have a high signal integrity, making them ideal for applications in telecom and industrial/automotive applications. In addition, the 71991-820LF can be used for vertical PC connections, signal transmission between motherboard and daughterboard, data transfer between two computer devices, and as a connector for LCD displays.
Because of its size and robust construction, the 71991-820LF connector is often used for applications in the automotive and industrial electronics fields. It is also used in consumer electronics, such as cell phones, game consoles, and tablets.
Working Principle
The 71991-820LF is a type of rectangular connector that uses a bowden-style wiring method. This means that instead of having exposed wires that must be manually connected, the connector provides insulation between the pins. This helps to prevent accidental shorting or other faulty connections.
The pins of the connector are held in place by metal tubes that are pinned to the back of the connector. This style of construction helps ensure that the pins are held in place firmly and that there won\'t be any loose connections. The pins themselves are made from copper to ensure that they have good conductivity and won\'t cause interference.
When connecting two pieces of the 71991-820LF connector, the pins are pushed through the insulation material. This insulation helps to reduce crosstalk between the two pieces and helps ensure a high signal integrity. Once the pins are pushed through the insulation, the metal tubes that secure them are released, holding the pins in place.
The 71991-820LF connector is an ideal solution for high frequency data transmission applications. Its rugged construction ensures a secure connection and the insulation material helps to reduce crosstalk. This makes it an ideal choice for a wide variety of applications ranging from automotive and industrial electronics to consumer electronics.
