Description

Technical Field

[0001] The utility model relates to the field of USB wire harness production, and more specifically, to a clamping device for USB wire harness production. Background Art

[0002] USB harnesses are very common in people's lives. USB harnesses can be used to transmit data or charge devices, which greatly facilitates people's work and life. USB harnesses are often composed of cables and two connectors. When producing USB harnesses, the two connectors need to be connected to the two ends of the cable respectively. When assembling the cable, a clamping device is generally required to clamp the wire. The existing clamping device generally lacks a supporting structure and can only fix the wire but cannot support the wire, which makes it inconvenient to connect the wire to the connector. In addition, the existing clamping device cannot be adjusted according to the length of the cable and can only clamp part of the wire, so it is impossible to clamp multiple parts of the wire, which makes it inconvenient to produce the wire. At the same time, there are many types of connectors for USB cables, and the existing clamping device is inconvenient to fix different USB connectors, which affects the production of USB harnesses.
