Document Type and Number:
WIPO Patent Application WO/2024/021866
Kind Code:
A1
Abstract:
A transmission line assembly, a printed circuit board assembly and an electronic device, which relate to the technical field of printed circuit boards, and solve the problem of a signal line having a great signal loss. The transmission line assembly comprises a shield cover and a signal line; the shield cover is connected to a grounding end; the shield cover has an accommodating space, the accommodating space being provided with a first opening and a second opening; the signal line comprises a first end and a second end, which are arranged opposite each other; the signal line is arranged in and passes through the accommodating space, and there is a gap between the signal line and an inner side wall of the accommodating space; and the first end passes through the first opening, the second end passes through the second opening, and at least one of the first end and the second end of the signal line is used for connecting to a signal end. The signal line is in an air medium, and thus the signal loss is effectively reduced. The wrapping of the signal line by the shield cover can prevent the radiation of the signal line from overflowing to interfere with other transmission lines. The shield cover and the signal line are welded to a printed circuit board by means of surface mount technology, such that the process cost and the process time can be reduced.
