D-Sub Connectors refers to a group of multi-pin communication and signal connectors, which is widely used in the industry and can be found on many different types of electronic equipment, ranging from PCs and servers to medical devices and industrial controls. DB19604-2 is one of the most common types of D-Sub Connectors.

DB19604-2, also known as DB4 connector, is a high-density multi-pin connector developed by Deutsch which has 20 pins in two rows. It is widely used in computer peripheral equipment and instruments. In addition, DB19604-2 generally uses the 4-40 pin, which has the advantage of high contact density.

DB19604-2 is a most popular application for power, signal, and data transfer. It is suitable for applications requiring up to four I/O lines in a very limited space. The signal ports are arranged in the order of ground terminal, signal terminal, and power terminal, which provides multiple layers of signal ground, signal, and power. It is also possible to provide, either directly or through additional circuits, direction changes between the signal lines. In this way, a two line connection is possible without changing the design of the circuit. In addition, due to its high-current power supply interface, DB19604-2 can directly provide up to 4A power, or provide up to 16A power through an additional circuit. Other design features of DB19604-2 include a high voltage input, easy assembly and disassembly, and secure connections.

The working principle of DB19604-2 is centered on the electrical connection between its pins and sockets. First, when connecting the DB19604-2 to its mating part, the pins of the plug are inserted into the sockets of the female connector. Then, the springing pressure of the pin and socket ensures good electrical contact, and the mechanical assembly also provides additional fixing. Finally, the insulating material between the guard pin and the contact pin prevents short-circuiting, ensuring the electrical safety of the connection.

In summary, DB19604-2 is a type of D-Sub connector with 20 pins in two rows. Its main applications are used in power, signal and data transfer. It has many advantages such as high contact density, high current power supply interface, easy assembly and disassembly, and secure connections. The working principle of DB19604-2 is based on the electrical connection between its pins and sockets.
