The USB female 4PIN connector is a common connector widely used in electronic devices for data transmission and power connection. Although most standard USB connectors (such as USB 2.0, USB 3.0, etc.) typically have multiple pins, some custom or simplified USB interfaces may only use 4 pins. The following is the detailed information of the connector:
main features
1. Pin configuration:
The 4PIN USB female connector usually corresponds to the basic configuration of USB 2.0, and the main pin functions are as follows:
Pin 1 (VBUS): Positive pole of power supply (>5V)
Pin 2 (D -): Data negative pole, used for differential signal transmission
Pin 3 (D+): Data positive pole, used for differential signal transmission
Pin 4 (GND): Grounding
2. Design and Shape:
USB female connectors are usually rectangular in design, making it easy to insert USB male connectors.
It can be installed on a printed circuit board (PCB) through soldering, plugging, and other methods.
3. Materials and Durability:
The materials used usually have good durability and insulation, such as plastic and gold-plated or nickel plated metals, to provide good electrical performance.
application area
1. Computer and accessories:
USB interfaces for commonly used devices such as keyboards, mice, printers, etc.
2. Charging equipment:
Charging interfaces for various portable electronic devices, such as power banks, Bluetooth earphones, etc.
3. Embedded systems:
Simplified USB interfaces may also be used for data transfer and power supply in some small embedded devices or products.
4. Industrial applications:
USB female connectors may also be used for data monitoring and management in certain industrial equipment.
Installation and maintenance recommendations
1. Welding technology:
Ensure the use of appropriate soldering techniques to solder the pins and avoid connector damage caused by overheating.
2. Cleaning and maintenance:
Regularly inspect connectors to ensure they are free of dust, dirt, or corrosion and maintain good electrical contact.
3. Functional testing:
Perform functional testing every time a new component is replaced or installed to ensure that data transmission and charging functions are functioning properly.
4. Physical protection:
Add physical protection to the connector, such as a plastic cover or dust cover, to prevent foreign objects from entering the interface.
summary
The USB female 4PIN connector plays a fundamental and important role in electronic products, especially in portable devices and simplified data connection systems. Choosing appropriate connectors and paying attention to installation details can ensure the stability and reliability of the system. If you have further questions or need specific technical parameters, please feel free to contact the technician!
