Description

Technical Field

[0001] The utility model relates to the field of adapter cards, and more specifically to a transversely extended adapter card structure. Background Art

[0002] Generally, when using a computer, an expansion card is usually inserted into the motherboard of a computer host to increase the functions of the computer host and make the computer more powerful. However, due to the limitation of the housing appearance of the computer host, an adapter card is often needed to connect the expansion card and the motherboard to change the position of the expansion card relative to the motherboard so that the expansion card can be accommodated in the housing. Especially for the existing low profile computer host, because of its thinner and flatter appearance, using an adapter card to change the position of the expansion card relative to the motherboard has become an even more indispensable step.

[0003] However, when the adapter card is vertically inserted into the motherboard, the adapter card will be affected by the weight of the expansion card inserted thereon, causing the adapter card to tilt toward the side of the expansion card, resulting in a poor electrical connection between the adapter card and the motherboard, thereby affecting the customer's use of the computer, and even causing the adapter card and the motherboard slot to be permanently deformed and damaged. A Chinese utility model patent discloses an auxiliary fixer for the adapter card (application number CN01230044.6). When the adapter card is inserted into the motherboard, the auxiliary fixer clamps the adapter card motherboard through the groove thereon to prevent the adapter card from tilting. However, the auxiliary fixer is fixed to the computer motherboard by screws. The auxiliary fixer requires a hole to be drilled on the computer motherboard for installation. The computer motherboard is covered with circuits, which can easily damage the circuits when drilling the holes, causing damage to the computer motherboard, or even making it impossible to find a position on the computer motherboard to install the auxiliary fixer. Utility Model Content

[0004] In view of the above-mentioned defects in the prior art, a horizontal expansion riser card structure is provided.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a horizontally extended adapter card structure, including an adapter card mainboard, a gold finger is arranged on one side surface of the adapter card mainboard, a plurality of adapter card slots parallel to the gold finger are arranged on a surface of the adapter card mainboard adjacent to the gold finger, the plurality of adapter card slots are arranged at intervals from the gold finger to the surface opposite to the gold finger, the plurality of adapter card slots are all electrically connected to the gold finger, a mounting plate is arranged on the surface of the adapter card mainboard away from the adapter card slot, an end of the mounting plate opposite to the gold finger and away from the gold finger extends a connecting portion in a direction away from the adapter card mainboard, a connecting portion through hole is arranged on the connecting portion, a sliding plate is provided for limiting sliding on the surface of the mounting plate away from the adapter card mainboard, the sliding plate slides along the extending direction of the adapter card slot, an extension plate is extended on the end surface of the sliding direction of the sliding plate in a direction away from the adapter card mainboard, and the extension plate through holes are all arranged on the extension plate.

[0006] Preferably, the plurality of adapter card slots are arranged at equal intervals.

[0007] Preferably, the sliding plate is provided with two strip-shaped sliding plate through holes, the axes of the two sliding plate through holes are perpendicular to the mounting plate, the mounting plate is provided with external threaded columns inserted in the sliding plate through holes and sliding relative to the sliding plate, and each of the external threaded columns is threadedly connected with a nut.

[0008] Preferably, two sliding plates are provided, the two sliding plates are symmetrically arranged, and the two extension plates are arranged at one end of the two sliding plates away from each other.

[0009] Preferably, the connecting portion is an L-shaped plate structure, the connecting portion and the mounting plate form a slot, and the connecting portion through hole is arranged on a surface of the connecting portion parallel to the mounting plate.

[0010] Preferably, an expansion card is inserted into any one or more of the adapter card slots, and the expansion card is electrically connected to the adapter card slot.

[0011] Preferably, the extension plate through hole is a strip-shaped extension plate through hole.

[0012] The beneficial effect of the utility model is that when the adapter plate is plugged into a position on the computer motherboard where the mounting plate is away from the inner wall of the casing, the extension plate of the sliding plate and the casing of the host are connected by sliding the sliding plate; when the adapter plate is plugged into a position on the computer motherboard where the mounting plate is close to the inner wall of the casing, the extension plate of the sliding plate and the casing of the host are connected while the connecting part of the mounting plate and the casing of the host are connected, which makes the fixation more stable. In summary, the adapter card is fixed by the sliding plate and the mounting plate, so that the adapter card will not tilt or even deform, which makes the insertion between the adapter card and the motherboard stable.
