In recent years, Peripheral Component Interconnect Express (PCI-E or PCIe) has been widely adopted in the computer-related field, which has a fast speed and is sufficient to replace various existing internal buses, and meanwhile, the Peripheral Component Interconnect Express (PCI-E or PCIe) further supports Hot plug (Hot swap) and has better portability and modularization potential.
The Optical Copper wire connection (Oculink) interface based on the peripheral component interconnect express standard 4.0 uses a Copper cable as a main connection medium, provides a single channel with a bandwidth of 8 gigabits per second (8Gb/s), supports four channels, and can achieve a total bandwidth of 32 gigabits per second (32Gb/s), has a small volume, and can provide standard connection for connecting a future small or light and thin platform with an external device so as to increase internal expandability and external diversification.
However, the optical copper wire connection interface still has the disadvantage that improvement is needed. Most of traditional optical copper line connection interfaces still use the mode of connector and cable to connect, and it is with high costs not only, whole length is difficult to reduce, also causes the difficulty in the installation. When a less protective device, such as an adapter card without a housing or a hard disk that is extremely sensitive to shock, is to be connected to the optical copper connection interface connector, such connection would result in the device itself being exposed and only partially suspended in the air by the connector, resulting in instability in use.
Therefore, there is a need for an improved Oculink electronic device having a flexible circuit board that can solve the drawbacks of the prior art to improve stability, and can be used in different installation situations to reduce the required space and improve protection.

Another objective of the present invention is to provide an Oculink electronic device with a flexible circuit board, which can improve the versatility of the existing product by placing the electronic components on the second rigid circuit board. In addition, the bendable component and the first shell which can rotate relative to the second shell can realize the rotating function and effectively protect the internal electronic components, so that the stability and the protectiveness of the product are improved, and the interference between the internal electronic components and other surrounding electronic components can be avoided.
In order to achieve the above objectives, a preferred embodiment of the present invention provides an Oculink electronic device having a flexible circuit board, which includes an Oculink connector, a first rigid circuit board, a second rigid circuit board and a flexible circuit board.
