1. Features of D-SUB connector
1. Easy plugging and unplugging: The D-SUB connector adopts a push-pull plug-in design, which is convenient and fast, and can quickly connect and disconnect the circuit.
2. Reliable contact: The contact of the D-SUB connector is made of high-quality metal material, which is precisely processed and gold-plated, and has good conductivity and long service life.
3. Wear resistance: The contact of D-SUB connector is made of wear-resistant material, which can withstand frequent plugging and unplugging and long-term use, and is not easy to be damaged.
4. Multiple specifications: D-SUB connectors have multiple specifications, suitable for different cables and sockets, and the appropriate specifications can be selected according to actual needs.
5. High reliability: The design of D-SUB connectors focuses on reliability. After strict quality control and testing, it can ensure that there will be no problems such as poor contact or short circuit during use. -
2. Classification of D-SUB connectors
Solder cup D-Sub connector: This connector meets commercial industrial standards and can be paired with any docking solder cup D-Sub connector. The contacts are electroplated with flash gold, and the connector insulator meets the UL94V-0 standard. The maximum wire size is 20 AWG, and 9, 25, 37 and 50 pin specifications are available.
Crimp D-Sub connector: Crimp D-Sub connectors meet commercial industrial standards and can be used for most standard D-Sub male connectors. Compatible with 20-28 AWG wire range, available in 9, 15, 25 and 50 pin sizes.
Punch-type D-Sub connector: This connector is easily soldered into the through-hole of the printed circuit board or used in many other applications. Solder placement follows a standard footprint, and gold-plated contacts ensure long life. As an industrial standard commercial DB37 female PCB type connector, it has standard mounting holes for application flexibility. -
3. D-SUB connector insulation is poor
Performance: short circuit, insulation resistance is too poor.
Cause: high humidity in the use environment, serious pollution, water or other liquids penetrate into the insulator, etc.
Solution: Improve the use environment, clean the inside of the insulator, and replace the insulator. -
4. FAQ of D-SUB Connector
What is the reason for no signal in D-SUB connector?
Performance: No signal.
Solution: Check whether the signal cable is plugged in properly and ensure stable connection. 3.
D-SUB connector causes the monitor to fail to display.
Performance: The monitor cannot display.
Solution: Adjust the computer resolution to the highest resolution supported by the monitor.
What is the reason for poor connection of D-SUB connector?
Performance: Poor connection.
Cause: The pin is exposed and easily damaged.
Solution: Use a protective cover to avoid pin exposure and operate carefully.
