Description

  The present invention relates to printed circuit bus design, and more particularly to a flexible printed circuit board bus having clusters and sliding regions.

Currently, in the printed circuit board technology, the flexible printed circuit (FPC) is currently the most advanced technology. The flexible printed circuit board is light in weight, small in volume, dynamically curved, and can change its shape due to elasticity. It is especially suitable for assembly conditions of system products of various shapes, increasing wiring density, and flexible. It is used as a printed circuit board carrier for signal connection and member assembly, taking advantage of its characteristics such as being bent into
Since the flexible printed circuit board can be connected to a main drive, passive, or a module member, the flexible printed circuit board has such a characteristic of structure.

  In recent decades, flexible printed circuit boards have been widely applied to various system products. In particular, it is used for thin and light electronic products such as consumer electronic products such as mobile phones, digital cameras, personal computer peripherals, flat panels and game machines. The flexible printed circuit board has high growth potential in the consumer product area other than the flat panel, and the use of the flexible printed circuit board as a transmission interface is an indispensable technology in the electronic industry.

Flexible printed circuit boards are mainly used for signal connection parts of electronic products such as folding and rotating, and are most often applied to Hinge Part of electronic products. Folding type (Clamshell) and sliding type (Slip), flip type (Flip), and three-dimensional rotation type devices are most benefited by flexible printed circuit boards among electronic products.
As technology advances day by day, the external structure and functional design of electronic products are further diversified, and as a result, the structural design of flexible printed circuit boards is becoming increasingly diverse.

  However, the structure design of the current flexible printed circuit board bus is mainly a single folding, sliding, flip, or three-dimensional rotation structure. In many electronic and communication products, the flexible printed circuit board is installed on a rotating shaft structure having a shaft hole. This rotating shaft structure has a single-axis structure and a biaxial structure design. For example, a slide panel of a slide type mobile phone has a single-axis rotating shaft structure as an assembly member on which a flexible printed circuit board is placed. The rotary shaft structure of the biaxial structure becomes an assembly member on which the flexible printed circuit board is placed.

Technology is constantly evolving, and consistent electronic and communications products have already emerged that are similar to sliding and rotating panels.
However, although the existing flexible printed circuit board according to the above-mentioned conventional technology is applied to this type of conformable electronic product, the operation of the rotating shaft structure is affected by the design of the conventional bus in part of the rotating structure. As a result, the corner structure of the bus has a problem that the rotating shaft structure is damaged by being compressed, colliding, or rubbing, and the service life of the electronic product is shortened.

  The present invention has been made in view of such conventional problems. In order to solve the above-mentioned problems, the present invention provides a flexible printed circuit board bus having a cluster area that improves the problems that have occurred when the conventional printed circuit board bus is applied to these electronic and communication products.
