Description
本發明係關於一種板卡固定裝置，尤指一種電子設備之板卡固定裝置。 The present invention relates to a card fixing device, and more particularly to a card fixing device for an electronic device.
當前，個人電腦、伺服器等現代電子設備發展迅速，CPU成為該等電子設備內部發熱量最大之元件，人們經常利用散熱裝置來對其進行主動散熱。而某些板卡，如集成了複數記憶體晶片之電路板、擴充卡等，儘管其在工作時也產生較大熱量，但沒有受到應有之重視。 At present, modern electronic devices such as personal computers and servers are developing rapidly, and CPUs are the components that generate the most heat inside such electronic devices. People often use heat sinks to actively dissipate them. Some boards, such as boards that integrate multiple memory chips, expansion cards, etc., do not receive the attention they deserve, although they generate a lot of heat during operation.
一般，該等板卡均是借助卡扣並排地固定於電子設備內，但是該等卡扣大都位於板卡之一端或兩端，比如固定電路板之卡扣結構便位於電路板兩端，這樣，該等卡扣就會佔據兩相鄰板卡之間之空間。而該等空間正是為該等板卡散熱之氣流流經之通道，如此，該等卡扣便會阻擋氣流之通過，使流經兩個板卡之間之氣流減少，很不利於板卡散熱。 Generally, the cards are fixed to the electronic device side by side by means of a buckle, but the buckles are mostly located at one end or both ends of the card, for example, the buckle structure of the fixed circuit board is located at both ends of the circuit board, so that These buckles will occupy the space between two adjacent boards. These spaces are the passages through which the airflow of the boards flows, so that the buckles block the passage of the airflow, reducing the airflow between the two boards, which is not conducive to the board. Cooling.
因是，實有必要對習知之板卡固定裝置進行改良，以消除上述缺失。 Therefore, it is necessary to improve the conventional card fixing device to eliminate the above-mentioned defects.
鑒於以上內容，有必要提供一種利於散熱之板卡固定裝置。 In view of the above, it is necessary to provide a card fixing device that is advantageous for heat dissipation.
一種板卡固定裝置，用於將一板卡固定於主機板之連接器，該連接器設有複數卡槽，該板卡固定裝置包括至少一個由板材彎折形成之卡固件，該至少一卡固件包括一頂壁及自該頂壁兩側同向彎折延伸之兩側壁，該頂壁內側設有一可彈性抵置於板卡頂面之彈片，每一側壁之下部設有開槽並形成兩彈性部，每一彈性部進一步延伸形成具有卡突之卡腳，當板卡插接於主機板之連接器時，將板卡夾持於該卡固件之兩側壁間，每一側壁之兩卡腳穿設於對應之卡槽，該兩卡腳之卡突分別扣持於相應卡槽邊緣而固定該板卡，每一彈性部底端向遠離對應側壁之方向延伸形成一L形扣持部，每一扣持部包括一支撐段，該支撐段可貼靠在該連接器之頂面，該彈性部之卡腳是自該支撐段彎折形成。 A card fixing device for fixing a card to a connector of a motherboard, the connector being provided with a plurality of card slots, the card fixing device comprising at least one card member formed by bending a plate, the at least one card The firmware comprises a top wall and two side walls extending from opposite sides of the top wall, and a spring piece elastically resisting the top surface of the card is provided on the inner side of the top wall, and a groove is formed on the lower part of each side wall and formed Two elastic portions, each elastic portion further extending to form a card having a card protrusion. When the card is inserted into the connector of the motherboard, the card is clamped between the two sidewalls of the card, and each side wall The card legs are disposed in the corresponding card slots, and the card protrusions of the two card legs are respectively fastened to the edges of the corresponding card slots to fix the card card, and the bottom end of each elastic portion extends away from the corresponding side wall to form an L-shaped buckle.
