1.product introduction
The Universal Serial Bus (USB) connector is an interface standard used to connect computers to external devices.It allows the connection of external devices such as mice, keyboards, storage devices, printers, etc., through a single port.With convenience and reliability, USB connectors are widely used in personal computers and mobile devices.
Today, various device types use Universal Serial Bus (USB) as the standard connection type.They have created a compact, low-cost interface that facilitates computer communication and plays a pivotal role in the electrical appliance industry.
At present, there are different types of USB connectors available, and have different functional characteristics, mainly divided into the following:
USB Type-A: Universal, common USB interface, often used to connect computers or chargers.
USB Type-B: Mainly used to connect external devices, such as printers or scanners.
USB Type-C: The latest USB interface standard, with higher data transfer speed and more features, such as two-way data transfer and charging.
Micro-USB: Commonly used in mobile devices such as smartphones and tablets.
Mini-USB: A smaller USB port, commonly used in digital cameras and MP3 players.
Lightning cable: It is a relatively durable data cable. The exterior of the data cable is made of high-strength steel material, and the durability reaches industrial level.
2.product parameter
