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. Applications of D-SUB full range of connectors
1. Computer field: D-SUB connectors are widely used in the computer field, such as the connection of external devices such as monitors, keyboards, mice, etc.
2. Communication field: D-SUB connectors can be used for signal transmission between various communication devices, such as telephones, fax machines, routers, etc.
3. Industrial control field: D-SUB connectors are widely used in the industrial control field, such as the connection of PLCs, sensors, actuators and other equipment.
4. Automation field: D-SUB connectors can be used for signal transmission and power supply in automation equipment, such as robots, automated assembly lines, etc.
5. Other fields: In addition to the above fields, D-SUB connectors can also be used in other fields such as security, lighting, and medical equipment. -
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. 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?
