Problems solved by technology

However, this type of scheme, that is, the scheme of longitudinally cutting and arranging cables, also has corresponding deficiencies. For example, the cables that have been cut and dispersed scrape each other when the rotating shaft rotates, which may affect the layer on the surface; the relative position of the arranging cables is not fixed. , leading to changes in the distributed capacitance of the cable; on the other hand, the cable itself needs to be cut, which increases the process steps and time cost

Embodiment 1

[0036] Such as figure 1 As shown, a top view of the embodiment of the present invention; the piercing section 200 is a long and narrow sheet, which is formed on the same flexible circuit board as the first joint 10 and the second joint 20; the first joint 10 includes three parts respectively The transition section 100, the bending section 110 and the first cable end 120, and the extension direction of these three parts is perpendicular to the extension direction of the piercing section 100 - the purpose of this setting is to make the first joint 10 fold (or After crimping), its form can form a shape with a width comparable to that of the passing section 200, so that it can pass through the shaft hole; usually, when the first joint 10 is folded (or crimped), the transition section 100 and the first cable end The shape of 120 basically remains unchanged, but the bending section 110 is curled or bent, so that the bending will not stretch and damage the static discharge layer on t...

Embodiment 2

[0041] Such as figure 2 , the top view of the second embodiment of the present invention; compared with the embodiment, the penetration section 200 and the second joint 20 are the same, the difference is the first joint 10 . In the second embodiment, the first joint 10 also has the transition section 100, the bending section 110 and the first cable end 120, but the wiring from the piercing section 200 does not pass through the via hole, and the second is to directly pass through the transition section on both sides. 100. The bending section 110 is finally connected to the golden fingers on the first cable end 120 in one-to-one correspondence; the relationship between the width W1 of the transition section 100, the width W2 of the first cable end, and the width W3 of the piercing section are all implemented in the same manner example one.

[0042] to combine Figure 4 It can be seen figure 2 Sectional detail of part AA in middle. In the transition section 100, its antista...

Embodiment 3

[0044] Such as Figure 5, the top view of the first joint of the third embodiment of the present invention; the passing section 200, the transition section 100, the bending section 110, the first cable end 120 and other unmarked parts of this embodiment are the same as those of the first embodiment; the difference What is more important is that there is a ground welding spot 109 at the top of the transition section 100 , and the ground welding spot 109 communicates with the conductive trace serving as the ground wire in the penetration section 200 .

Abstract

The invention discloses an aperture flat cable applicable to multi-directional rotating shafts, which is characterized by comprising a crossunder section and a first connection and a second connection at two ends. The crossunder section is a long and narrow slice, which adopts flexible material as a substrate and is provided with conductive wires on the surface; the first connection is positioned at one end of the crossunder section and provided with a transition section connected with the tail end of the crossunder section, the transition section extends along the direction perpendicular to the crossunder section to form a first flat cable terminal, a bendable crease is arranged between the first flat cable terminal and the transition section, the largest widths of the transition section and the first flat cable terminal are both not more than the diameter of a shaft hole to be passed; and the largest width of the crossunder section is not more than that of the transition section. The flexible connection in the scheme and the crossunder section form to be a shape capable of passing through the rotating shaft hole, and the largest width of the crossunder section is less than the diameter of the rotating shaft hole, therefore, the installation is convenient, and the aperture flat cable is not deformed and even damaged by torsion due to the influence of relative rotation of the rotating shaft; and simultaneously, the crossunder section is not relatively scrapped so that the electrical and mechanical properties of the aperture flat cable are stable.

Description

technical field [0001] The invention relates to a component for electrical connection, in particular to a perforated cable suitable for multi-directional rotating shafts. Background technique [0002] Miniaturized electronic devices have more and more applications in various fields of production and life, and their shapes are ever-changing, and their functions are also rich and diverse. In addition to electronic parts, there is a type of electronic equipment that has structures that can rotate, bend or / and slide relative to each other. Common structures of this type include: foldable or simultaneously rotatable LCD screens and operation panels of handheld multimedia devices; automatic control of multi-axis movable probes, etc. With the development of technology, the digitalization of these small devices is getting higher and higher, and the amount of internal data transmission is correspondingly large. At the same time, the volume may become more and more limited, not only ...
