What is a USB cable?
A USB cable is a multi-core cable designed to connect computers and electronic devices for data transfer and power delivery. It is commonly used in mice, keyboards, video game equipment, instruments, andvarious computer peripherals. A standard USB cable contains multiple copper conductors, insulation layers, shielding, and an outer jacket to ensure stable performance.

What does a USB cable look like?
A typical USB cable consists of:
Internal tinned or bare copper stranded conductors
Color-coded insulation for each core
A shielding layer to reduce electromagnetic interference
An outer protective jacket, commonly PVC USB cable or silicone USB cable
Externally, USB cables may appear round or flat, flexible or reinforced, depending on application requirements and material selection.
Our USB Cable is a multi-core computer cable designed for reliable signal transmission and power supply.
