Description

Signal bus line capable of overlapping and assembling

Technical Field

The present invention relates to a signal transmission cable, and more particularly, to a signal transmission cable capable of being stacked and combined.

Background

The conventional flat cable structure is generally a flat cable structure formed by arranging a plurality of wires covered with an insulating layer in parallel, and can be applied to various electrical equipment, electronic equipment, computer equipment and communication equipment for signal transmission.

In recent years, the technology of flexible printed circuit board is also widely applied to the flat cable structure. In the conventional Flexible Printed Circuit (FPC) cable products, different FPC structures such as single-sided board, double-sided board, multi-layered board, multi-sided board, etc. can be adopted according to the requirements of different transmission lines. The structure of double-sided board or multi-layer board or multi-surface board can be used to have more transmission lines in the same flat cable product, and the wiring technique of jumper can be used to change the position of contact pin.

Furthermore, the conventional flat cable design is only suitable for passing through a narrow penetrating space. However, in many electronic devices or communication devices, a hinge structure having a shaft hole is often used. For example, in the structure design of the communication mobile phone widely used at present, the cover plate or the screen is often combined on the mobile phone body by a rotating shaft structure. In order to transmit the electrical signal from the main body of the mobile phone to the cover or the screen, it is the current practice to use miniaturized flat cable products or bundles of very fine wires as the transmission lines for the signal.

Disclosure of Invention

The technical problems to be solved by the invention are as follows: when the flat cable is used as a signal transmission line in practical applications, although there is no problem in passing through a long and narrow penetrating space, it is very important whether the flat cable can withstand frequent bending or the number of times of bending, and whether the flat cable is good or not is generally measured by the degree of bending resistance. In the structure of the common single-panel flat cable, the lead wire is only arranged on one side of the flexible circuit substrate, so the flat cable generally has better bending resistance, and in the structure of the double-panel or multi-layer board, the flat cable is easily bent for many times due to the application and pulling relationship among different lead wire wires, and is then unusable. Although the flat cable has better bending resistance, it has less number of transmission lines, which is not in accordance with the current practical requirement.

Accordingly, in view of the shortcomings of the prior art, the present invention is directed to a signal cable that can be stacked and combined, wherein the folding structure can achieve bending resistance and a cable product with a large number of transmission lines.

Another objective of the present invention is to provide a signal cable with different connector assemblies, which can provide a flexible cable structure according to different pin requirements and connector positions.

Another objective of the present invention is to provide a signal cable with different circuit layout and pin position adjustment, which can be combined with the design of double-sided board, multi-sided board or multi-layered board to achieve the purpose of wire pin position adjustment and jumper wire for different occasions.

The technical means for solving the problems of the invention are as follows: the present invention adopts a technical means for solving the problems of the prior art, wherein a signal flat cable comprises a first flat cable and a second flat cable, and the first flat cable and the second flat cable are connected by a first connecting section and a second connecting section. A first connector is disposed at a first end of the first flat cable, and a second connector is disposed at a second end of the first flat cable or a second end of the second flat cable. The first connector and the second connector are connected by the signal lines arranged on the first flat cable, the second flat cable and the connecting section, and a foldable line is respectively formed in the first connecting section and the second connecting section, so that the second flat cable can be folded and overlapped on the first flat cable along the foldable line.

In an embodiment of the invention, the first flat cable and the second flat cable are one of a single-sided board, a double-sided board, a multi-layered board and a multi-sided board, and the first flat cable and the second flat cable may include a cluster section, the cluster section includes a plurality of parallel cutting lines cut along an extending direction of the flat cables to form a plurality of cluster flat cables, and each cluster flat cable is a cluster structure capable of being independently and freely bent.

Compared with the prior art, the invention has the following effects: through the structural design of the invention, the signal transmission flat cable can be applied to the application fields of different pin requirements and connector positions through simple overlapping combination. Besides being capable of being superposed and combined, the design of the invention also can give consideration to bending resistance and flat cable products with more transmission lines. Furthermore, the invention combines the design of double-sided board, multi-panel or multi-layer board to achieve the effect of more flexible circuit pin position adjustment and jumper wire. The present invention can also be combined with the structure of cluster section to fit through the spindle structure with shaft hole.
