Flexible circuit board adapter

The present invention relates to a flexible circuit board adapter, and more particularly to a flexible circuit board adapter that is electrically connected to conduct different flexible circuit boards.

Flexible Printed Circuit (FPC) has been widely used in the internal configuration of electronic devices and electrical connections between components. By virtue of the flexible and thin profile of the flexible circuit board, it can be flexibly set according to different structural types of the device, thereby effectively reducing the internal space usage and the overall volume of the electronic device.

When two different components use their own flexible circuit board as the electrical connection medium, in order to transmit signals between the components, it is necessary to set an adapter for the flexible circuit board to connect two. The flexible boards of the components. At present, most of these adapters need to be used as a base through the added circuit board, as a signal transmission path between the flexible circuit boards connected to the adapter, which is cumbersome in circuit and structure configuration and increases installation cost. In addition, the adapter is generally used in combination with the flexible circuit board adapter, and a certain space must be reserved in the periphery of the adapter to facilitate the insertion of the flexible circuit board, which is easy to cause space limitation.
