Description

Configuration method of expandable interface structure

本發明係有關於一種可擴充式介面結構之配置方法，尤指涉及一種主介面卡連接數個子介面卡之板對板堆疊式積木架構，特別係指能把傳統的M.2介面無限擴充，提供多個介面可以不斷地變動、組合，即可以將M.2轉換成HDMI、或SDI…等，產生很多線路，以達成彈性擴充之目的者。The invention relates to a configuration method of an expandable interface structure, in particular to a board-to-board stacked building block structure in which a main interface card connects several sub-interface cards, and particularly refers to an infinite expansion of a traditional M.2 interface. Provide multiple interfaces that can be continuously changed and combined, that is, M.2 can be converted to HDMI, or SDI, etc., generating many lines to achieve the purpose of flexible expansion.

M.2或稱下一代規格（Next Generation Form Factor, NGFF），其係結合多家電子業者為固態硬碟（Solid State Drive，SSD）量身訂作之新標準規範，並能完全支援目前主流之SATA與PCIe介面，並取代常見的mSATA介面。另外，該M.2（又稱NGFF）規範的體積輕薄短小、省電及傳輸速度快，且不同尺寸之標準設計，可讓SSD應用更靈活運用。因此，目前電子裝置內裝設有M.2連接器，以供SSD卡插接，以讓電子裝置之資料存取方式從傳統的硬式磁碟進化為體積更小、速度更快之固態硬碟。然而，市面上M.2連接器的介面太小，導致要轉換成不同介面非常麻煩，即便多層處理也僅能暫時解決問題，但整體結構缺乏彈性，無法轉換成各種介面，或者是提供更多路徑，不利於使用者自行搭配、組裝。此外，M.2連接器之插接槽的槽口方向因與電路板之表面呈平行配置，讓插設在M.2連接器上之SSD卡也與電路板之表面呈平行配置，惟此將會佔據電路板上相當比率之配置空間，使電路板必須預留面積給SSD卡容設，如此一來電路板可安裝電子零件之面積也會減少，進而影響電路板之使用效率。有鑑於此，市場上即有人提出一種擴充裝置，主要是在一塊電路板上設置多個從屬連接器，並藉由一傳輸線連接電子裝置之電路板上的一主連接器，以將該主連接器擴充為該多個從屬連接器使用（如中華民國專利案第M469664號）。舉例而言，目前市場上常見之USB集線器就是屬於此類產品。惟，此類產品通常係用來擴充同一種介面的連接器之數量，例如上述USB集線器即是將一個USB主連接器擴充為多個USB從屬連接器。目前在市場上實未見到有可將一主連接器擴充為多個不同介面的從屬連接器來使用之擴充裝置。若使用者欲使用不同之介面來連接電子裝置，則需要再使用額外之轉接器，以將上述之從屬連接器轉換為所需之介面，相當麻煩。如此看來，現有之擴充模組實仍然無法完全解決電子裝置上的連接器之數量、組裝彈性、種類不敷使用之問題。故，ㄧ般習用者係無法符合使用者於實際使用時之所需。M.2, or Next Generation Form Factor (NGFF), is a new standard specification tailored for Solid State Drive (SSD) by multiple electronics companies, 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) specification is light, thin, short, power-saving, and fast in transmission speed, and the standard design of different sizes can make SSD applications more flexible. Therefore, the M.2 connector is currently installed in the electronic device for SSD card insertion, so that the data access method of the electronic device has evolved from the traditional hard disk to a smaller and faster solid-state hard disk . However, the interface of the M.2 connector on the market is too small, which makes it very troublesome to convert to a different interface. Even if the multi-layer processing can only temporarily solve the problem, the overall structure lacks flexibility and cannot be converted to various interfaces, or provide more The path is not conducive to the user's own matching and assembly. In addition, the slot 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. 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 can be installed with electronic components will be reduced, which will affect the efficiency of the circuit board. In view of this, someone on the market has proposed an expansion device, which is mainly provided with multiple slave connectors on a circuit board, and a master connector on the circuit board of the electronic device is connected by a transmission line to connect the master The device is expanded to be used by the multiple subordinate connectors (such as No. M469664 of the Republic of China Patent Case). For example, the USB hubs currently on the market are such products. However, such products are usually used to expand the number of connectors of the same interface. For example, the above USB hub expands a USB master connector into multiple USB slave connectors. At present, there is no expansion device that can be used to expand a master connector into multiple slave connectors with different interfaces. If users want to use different interfaces to connect electronic devices, they need to use additional adapters to convert the above-mentioned slave connectors to the required interface, which is quite troublesome. From this point of view, the existing expansion modules still cannot completely solve the problems of the number of connectors, assembly flexibility, and insufficient types of connectors on electronic devices. Therefore, general users cannot meet the needs of users in actual use.
