Description

Technical Field

[0001] The utility model relates to the technical field of wire harness cutting, and more specifically, to a wire cutting structure for producing an HDMI wire harness. Background Art

[0002] HDMI cable harness is a cable combination used to transmit high-definition video and audio signals. It is composed of multiple HDMI cables bundled together, usually including 19 wires, used to transmit video, audio and other control signals.
