Description

Technical Field

[0001] The utility model relates to the technical field of connecting wires, in particular to an electronic connecting wire that is easy to plug and unplug. Background Art

[0002] Electronic connecting wires are one of the components that connect electrical circuits. They mainly play the role of electrical connection and signal transmission between devices and components, components and cabinets, systems and subsystems, and prevent signal distortion and energy loss between systems. Their quality is related to the reliability of the overall operation of the system equipment.

[0003] For example, a multi-interface electronic connecting cable with publication number CN218975988U is provided with a wire-reeling assembly. When the device is not in use, the wire can be wound on a wire reel, and then the end is placed in a wire-cage slot. The tensioning spring pushes the movable clamp forward so that the end of the movable clamp clamps the end of the wire, so that the wire can be stored and fixed, and the situation of entanglement caused by excessively long wires can be prevented. However, the connecting cable lacks a locking structure. When the connecting cable is used to connect an electronic device, the pulled-out connecting cable will be pushed by the spring to move into the wire box, and the connecting cable may be detached from the electronic device, affecting the use of the connecting cable. For this reason, an electronic connecting cable that is easy to plug and unplug is proposed as an improvement. Utility Model Content
