Description

Circuit connection bus capable of changing corresponding pin position

Technical Field

The present invention relates to a signal transmission cable, and more particularly, to a circuit connection cable with changeable pins.

Background

The conventional flat cable structure is generally a flat cable structure formed by arranging a plurality of conductive wires covered with an insulating layer in parallel, and can be applied to various electrical equipment, electronic equipment, computer equipment and communication equipment for transmitting signals. The conventional flat cable has no problem when being applied between fixed connection members, but cannot meet the requirement when being applied to the application requiring matching with the rotating shaft structure.

In many electronic devices or communication devices, a hinge structure 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 electric signal from the main body of the mobile phone to the cover or the screen, the current practice is to use a miniaturized flat cable product or a bundle of very fine wires as the signal transmission line.

Although the method of using miniaturized or very fine wire bundle as the transmission line of signal is barely suitable for the requirement of signal transmission, the size of the rotating shaft member cannot be reduced, so the mechanism design of the whole mobile phone main body is greatly limited.

Furthermore, in the application field of the current mobile phone design or notebook computer, the number of signals transmitted through the rotating shaft member is increasing, the size of the rotating shaft member is also decreasing, and the rotating shaft structure is changed from a simple one-dimensional structure to a two-dimensional rotating shaft structure, so that the traditional flat cable design cannot meet the requirement. Under such a situation, even though the flat cable can pass through the shaft hole of the rotating shaft structure by using the conventional flat cable design, the operation of the rotating shaft structure is affected by the flat cable when the product is used, and the individual wires in each flat cable are constrained and twisted by the rotation operation of the user, which may cause damage to some wires in the flat cable.

In order to meet the above requirements, a cluster cable has been developed. Although such products can solve the problem of the flat cable passing through the axial hole, they have a great limitation in the pin design of the electronic components (e.g., connectors or solder joints) connected to the two ends of the flat cable. For example, in the original design of circuit base of electronic product, if the pins of the connector are fixed, the flat cable corresponding to the pins must be selected. If the two pins are different, the connection operation will be troubled. Meanwhile, when manufacturing the flat cable, flat cable manufacturers must develop various flat cable products with different foot positions for selection, so as to meet the requirements of various application occasions. Therefore, the problems of research and development, manufacture, cost, production line arrangement and the like of manufacturers are caused, and inconvenience is caused when a user selects and uses the product.
