1. What is a D-SUB connector
The name of the D-SUB connector comes from the D-shaped appearance of its plug. It is a double-row cable connector widely used in computer, industrial automation and communication fields. This connector consists of two parts: a plug and a socket. It is connected through pinholes and pins. It can transmit video, audio and digital signals and provide a large number of grounding points.
The D-SUB connector is a compact and versatile connector mainly used to support power, analog, RF or digital signal transmission. It has a variety of models, options and accessories and is a very economical interconnection solution. -
2. 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. -
3. 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. -
4. FAQ of D-SUB Connector
What is the reason for slow data transmission of D-SUB connector?
Performance: Slow or interrupted data transmission.
Cause: Inherent characteristics of serial communication.
Solution: Use faster communication standards or increase communication stability measures 24.
D-SUB connector signal attenuation
Symptom: Signal attenuation.
Cause: Long-distance transmission characteristics.
Solution: Use higher quality cables or add signal amplifiers.
