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. Specifications and models of D-SUB connectors
There are many specifications and models of D-SUB connectors, and the common ones are D-SUB 9-pin, D-SUB 15-pin, D-SUB 25-pin and other series. These series have their own scope of application and characteristics. Users can choose the appropriate specifications and models according to actual needs. At the same time, the prices of different specifications and models are also different. Users need to consider factors such as cost and applicability when choosing.

3. Problems caused by poor contact of D-SUB connectors
Performance: increased contact resistance, circuit breakage, contact curtain movement, etc.
Causes: inadequate connection, insufficient contact area, dirt, corrosion, oxidation, etc.
Solution: Re-plug the connector, clean the connection part (use alcohol or other cleaning agents), replace the contact or connector. -
4. 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.
