Rectangular Connectors - Headers, Male Pins, 3-643787-3 application field and working principle.

Rectangular connectors are mainly used in the field of industrial machinery and electronic equipment. Rectangular connectors have the advantages of high contact reliability, good flexibility, and easy installation and maintenance. In the fields of home appliances, communications, instruments, medical equipment, robotics and industrial control, 3-643787-3 connector is increasingly used due to its small volume, high electrical performance and stable performance.

The 3-643787-3 rectangular connector, commonly known as the IDC header, also known as the CLIFF header. It is made of PVC as the insulating material, and the IDC terminal is covered with a metal protective shell. The 3-643787-3 connector consists of a casing, a tongue plate, a metal shield, and a cable line core. The tongue plate is composed of several rows of closed terminals, and there is a guide groove on the sides of the golden finger of the tongue plate that penetrates the terminal. There is also a tongue-processing protective cover on the outside of the terminal. The bottom of the terminal has metal contacts, which are evenly distributed and buried in the insulating plastic parts and cannot be touched directly by people.

The working principle of the 3-643787-3 connector is very simple. Its metal contacts are all mutual contact and insulation. When the terminal is connected to the corresponding position of the machine, the metal contact of the terminal and its corresponding contact point establish a complete conduction path. The current passes through the conduction path and is integrated to achieve the purpose of wiring. When the terminal is removed from the machine, the mutual contact between the metal contacts is automatically broken, and the electrical connection is cut off, so as to achieve the purpose of electrical isolation.

Due to the wide application of 3-643787-3 connectors in industry and their unique working principle, they have been widely used in medical equipment, communication, instruments, and industrial control. They can be applied to the connection between a variety of complex electronic equipment and can transmit power, control signals, and data signals. It is already widely used in production and life and has been recognized by the industry.
