Signal transmission flat cable suitable for using via shaft mechanism

Abstract

The wire arrangement is as following: signal transmission lines are formed on a flexible circuit base plate; signal transmission lines are arranged on the first connection section positioned on first end of the flexible circuit base plate; signal transmission lines are arranged on the second connection section positioned on second end of the flexible circuit base plate; signal transmission lines arranged on collection section between first and second connection sections are use for connecting corresponding signal transmission lines at first and second sections respectively. The connection section includes multiple pieces of row wires, which are formed by cutting the flexible circuit base plate along a cut line parallel to extended direction of the base plate. Thus, each connection of row wires can be bent freely. Each connection includes more than one signal transmission line. Lateral wings of first and second connection sections can be folded respectively.

Description

technical field [0001] The invention relates to a structural design of a signal transmission cable, in particular to a signal transmission cable suitable for passing through a rotating shaft mechanism. Background technique [0002] The traditional cable structure is generally a structure in which several wires covered with an insulating layer are arranged side by side to form a row of wires, which can be used in many kinds of electrical equipment, electronic equipment, computer equipment and communication equipment for signal transmission. There will be no problem when this kind of traditional cable is applied between fixedly connected components, but it cannot meet the requirements when it is applied in an application that needs to cooperate with the structure of the rotating shaft. [0003] However, in many current electronic devices or communication devices, the rotating shaft structure is often used. For example, in the structural design of the currently widely used com...

Problems solved by technology

[0004] Although the use of miniaturized or ultra-thin wire bundles as the signal transmission line can barely meet the needs of signal transmission, but the size of the rotating shaft component cannot be reduced, which will greatly affect the mechanism design of the entire mobile phone body. limit

Furthermore, in the current application field of mobile phone design or notebook computer, the number of signals transmitted through the rotating shaft component is increasing, the size of the rotating shaft component is getting smaller and smaller, and the structure of the rotating shaft is changed from a simple one-dimensional structure. The two-dimensional shaft structure is used, so the traditional cable design cannot meet this demand

In this situation, if the traditional cable design is still adopted, even if the cable can pass through the shaft hole of the shaft structure, the operation of the shaft structure will be affected due to the existence of the cable when the product is in use. , and the cable will also cause the individual wires in each cable to be restrained and twisted due to the rotation operation of the user. In severe cases, some wires in the cable will be damaged

[0005] Therefore, the conventional cable cannot meet the needs of modern electronic equipment and communication equipment with a rotating shaft structure
