Description

Expansion card fixture

The invention relates to an expansion card fixing device.

Electronic devices such as computers or servers usually have multiple expansion cards or expansion cards installed via a riser card. The front end of the expansion card (the one with the connector) is usually provided with a blank. Use the screw to secure the cover of the expansion card to the electronics case. In order to prevent long expansion card deformation, a fixing device is usually provided in the electronic device casing to fix the rear end of the expansion card. For an expansion card with dense electronic components on the back end, a support member is usually installed at the rear end thereof, so that the electronic device casing needs to be provided with another fixing device that cooperates with the support members. However, a fixing device of a conventional electronic device casing can usually only install one type of expansion card, which is inconvenient for installation and replacement of the expansion card.

In view of the above, it is necessary to provide an expansion card fixing device that can mount different types of expansion cards.

An expansion card fixing device for fixing a first expansion card or a second expansion card, wherein a rear end of the first expansion card is provided with a support member, and a rear end of the second expansion card is not provided with a support member, the expansion card fixing device The utility model includes a fixing frame, a circuit board fixed to the fixing frame and having an expansion card slot, a first fixing component and a second fixing component, wherein the fixing frame is provided with a first mounting structure for mounting the first fixing component and Removably mounting the second solid The second mounting structure of the fixing member, when the first fixing member and the second fixing member are simultaneously mounted on the fixing frame, the second fixing member shields the first fixing member, so that the second expansion card can be plugged in The expansion card slot is fixed by the second fixing member. When the second fixing member is removed from the fixing frame, the first fixing member is exposed, so that the first expansion card can be inserted into the expansion card slot. And the support member of the first expansion card is fixed by the first fixing member.

Compared with the prior art, the first and second fixing members of the expansion card fixing device can be simultaneously installed in the fixing frame and corresponding to the same expansion card slot, and the second fixing member is detachably mounted on the fixing frame. And shielding the first fixing member, when it is required to insert the expansion card without the support member in the expansion card slot, the second fixing member is mounted for fixing the expansion card without the support member, when the expansion is needed When the expansion card with the support member is inserted into the card slot, the second fixing member is detached to expose the first fixing member that can fix the support member of the expansion card.
