09652627810 Datasheet/PDFD-subminiature connectors are usually mounted on the back of the printed circuit to serve as the secondary communication port. The metal shell is used to protect against electromagnetic interference and other environmental driving forces to ensure the effectiveness of signal transmission. In the case of Panel Interface, several layers of circuit Board are connected by copper bolts, so as to reduce the cost of mass production and make it possible for the finished product connection mode to be customized.
The traditional D-sub connector is characterized by zinc alloy shell, crimping and direct soldering as the connection method, and characteristic impedance, crosstalk value, etc. are better controlled. The shell size can be divided into DB15, DB25, etc., while the outer shape of the shell is determined, the number of contacts is also constant. Commonly used contacts are DE9(DB9, D-SUB 9pin), DB15, DB25 and DB37.
D-SUB 15/25, as a kind of DB15/25D-sub socket, is composed of metal stamping shell + welding/welding contacts + terminal and other components. It is distributed to the back of the panel and is usually connected to the motherboard, keyboard, monitor, printer and other equipment, and its wiring is relatively complex. It is mainly used for data transmission and signal docking between computers and peripherals.
In terms of working principle, D-sub connectors are essentially a form of connection with multiple contacts that can be used to connect wires, cables, and PCB devices. This connection is commonly used for power, signal and data applications and can be used to join two components at a time, or to join three components using a “shell” connetor. Types of contacts used in D-Sub Connectors include flat contacts, crimped contacts, solder contacts, pneumatic and electrical contacts. The contacts are connected to various types of boards, cables, and connectors, including ground contacts, plug contacts, plug contacts with pins, plug contacts with flat contacts, and contactless contactless connectors.
