Description

Technical Field

[0001] The utility model belongs to the technical field of conversion joints, and particularly relates to a conversion joint for a signal transmission line. Background Art

[0002] Signal transmission line conversion connectors play a vital role in electronics and communication technology. Their main function is to adapt different types of signals or interfaces to ensure compatibility and smooth signal transmission. However, in actual use, due to the lack of unified connector models, there are many commonly used connector models on the market, which results in the conversion connector still unable to pair after docking, resulting in the inability to complete the docking between signal transmission lines, causing signal transmission interruption. At this time, another suitable connector is needed, affecting the normal signal transmission task.

[0003] Secondly, the signal transmission main line may need to be connected to multiple sets of connectors of different models at the same time when used in different situations to achieve the purpose of branch line signal transmission. Most common conversion methods use multiple sets of conversion connectors, resulting in too many connectors and too many wire groups in actual use, causing confusion in the wire groups.
