Description

The configuration method of the extensible interface structure

technical field

The present invention relates to an expandable interface structure, in particular to a board-to-board stacking building block structure in which a main adapter card connects several sub-adapter cards, in particular, the traditional M.2 interface can be infinitely expanded, providing multiple Each interface can be continuously changed and combined, that is, M.2 can be converted into HDMI, or SDI, etc., and many lines can be generated to achieve the configuration method of the expandable interface structure with flexible expansion.

Background technique

M.2, or Next Generation Form Factor (NGFF), is a new standard specification tailored for Solid State Drive (SSD) by a number of electronics manufacturers, and can fully support the current mainstream SATA and PCIe interface, and replace the common mSATA interface. In addition, the M.2 (also known as NGFF) interface is light, thin and short, saves power and has fast transmission speed, and the standard design of different sizes can make SSD applications more flexible.

Therefore, at present, an M.2 connector is installed in an electronic device for inserting an SSD card, so that the data access method of the electronic device evolves from a traditional hard disk to a smaller and faster solid-state hard disk. However, the interface of M.2 connectors on the market is too small, which makes it very troublesome to convert into different interfaces. Even multi-layer processing can only temporarily solve the problem, but the overall structure lacks flexibility and cannot be converted into various interfaces, or provide More paths are not conducive to the user's own matching and assembly. In addition, the notch direction of the insertion slot of the M.2 connector is arranged parallel to the surface of the circuit board, so that the SSD card inserted on the M.2 connector is also arranged parallel to the surface of the circuit board, but this will It will occupy a considerable proportion of the configuration space on the circuit board, so that the circuit board must reserve an area for the SSD card to accommodate, so that the area of the circuit board that can be installed with electronic components will also be reduced, which will affect the use efficiency of the circuit board.

In view of this, some people have proposed an expansion device in the market, which mainly includes a plurality of slave connectors on a circuit board, and is connected to a master connector on the circuit board of the electronic device through a transmission line, so as to connect the master connector. The connector is expanded to be used by the multiple slave connectors (eg, Taiwan Patent No. M469664). For example, the common USB hubs currently on the market belong to this type of product. However, such products are usually used to expand the number of connectors of the same interface. For example, the above-mentioned USB hub is to expand a USB master connector into a plurality of USB slave connectors. Currently, there is no expansion device in the market that can expand a master connector into a plurality of slave connectors with different interfaces. If the user wants to use different interfaces to connect the electronic device, he needs to use an additional adapter to convert the above-mentioned slave connector into the required interface, which is quite troublesome.

From this point of view, the existing expansion modules still cannot completely solve the problems of insufficient number of connectors, assembly flexibility, and types of electronic devices. Therefore, generally used ones cannot meet the needs of users in actual use.
