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
D-SUB connector connection is poor
Performance: shell damage, bayonet connector loose or stuck after plugging.
Cause: internal defects of the connector, external force damage.
Solution: Check and repair internal defects of the connector and avoid external force damage.
D-SUB connector oxidation What are the manifestations?
Performance: increased contact resistance.
Cause: environmental factors and current effects.
Solution: Clean and maintain the connector regularly, and use a protective cover to avoid pin exposure.
What problems are caused by deformation of D-SUB connector?
Performance: Affects contact area and stability.
Cause: Mechanical pressure or temperature change.
Solution: Avoid excessive mechanical pressure and check connector status regularly. -
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.
