Description

Fixed structure

The present invention relates to a fixed structure, and more particularly to a two-part expansion card fixing structure.

The expansion card is, for example, a circuit board such as a sound card or a display card that can expand the functions of the computer system. Generally, the expansion card is inserted into the motherboard, the backboard or the riser card to be electrically connected to other electronic components in the computer system. For the expansion card inserted in the riser card, the expansion card can be disposed side by side with the motherboard through the adapter card inserted in the motherboard, thereby flexibly utilizing the space inside the casing. However, compared with the direct insertion into the motherboard, the stability of the expansion card inserted in the adapter card is insufficient. Therefore, in order to firmly insert the expansion card into the riser card, a fixed structure for fixing the expansion card is provided on the casing.

However, different expansion cards have different sizes. For example, display cards or sound cards may have different lengths, and display cards of different specifications may have different lengths. However, the traditional fixed structure can only be matched to a single size expansion card. As a result, the flexibility of the fixed structure with different size expansion cards is insufficient, thereby increasing the inventory pressure of the fixed structure.

The present invention provides a two-piece fixing structure to prevent the flexibility of the fixed structure with the expansion card, thereby increasing the inventory pressure of the fixed structure.

The fixing structure disclosed in one embodiment of the present invention is for supporting an expansion card fixed to a riser card. The fixed structure includes a base frame and a transfer frame. The base frame comprises a plate body, a side plate, a first convex plate and a first buckle structure. The side panels stand on the board and are used to fix the riser card. The first convex plate protrudes from one side of the plate body. The first snap structure is located on the plate body. The adapter frame is detachably mounted on the base frame. The adapter frame includes an adapter plate, a first side wall, a mounting plate and a second buckle structure. The first side wall stands on the adapter plate. The mounting plate is fixed to one side of the adapter plate. The mounting plate and the adapter plate together form a slot. The second snap structure is fixed to the adapter plate. The first protruding plate is inserted into the slot, and the first fastening structure is buckled with the second fastening structure to fix the adapter frame to the base frame, thereby jointly supporting the expansion card.

According to the fixing structure disclosed in the above embodiment, since the adapter frame is detachably mounted on the base frame, not only when the adapter frame is fixed to the base frame, the base frame and the adapter frame can jointly support the expansion card having a long length. When the adapter is detached from the pedestal, the pedestal can also support the expansion card with a shorter length. In this way, the fixed structure can be matched to the expansion cards of different sizes, and the flexibility of the fixed structure and the expansion card is increased, thereby reducing the inventory pressure of the fixed structure.
