Description

Fixed components

The present invention relates to a fixing component, and in particular to a fixing component suitable for fixing an interface card.

Generally speaking, when assembling an interface card to a motherboard, the fixing assembly of the interface card needs to be installed to the motherboard first, so that the interface card is fixed to the motherboard through the fixing assembly. However, when the fixing assembly is currently assembled to the motherboard, it needs to be disassembled from the back of the motherboard, which makes it difficult to disassemble. In addition, when the length of the interface card is different, the heat sink on the fixing assembly needs to be removed before the interface card can be assembled, which is quite inconvenient.

This case provides a fixing assembly, which can be disassembled and assembled from the front of a motherboard.

The present invention provides a fixing assembly suitable for fixing an interface card on a motherboard. The motherboard has a plurality of fixing holes and a connector. The fixing assembly includes a base plate, a plurality of rivets and a moving part. The base plate is suitable for corresponding to the connector and is arranged on the motherboard, and has a plurality of through holes and a plurality of positioning structures, wherein these positioning structures are symmetrically arranged on opposite sides of the base plate, and these through holes correspond to these fixing holes respectively. These rivets are suitable for corresponding to these through holes respectively and are arranged in these fixing holes. The moving part is slidably arranged on the base plate relative to the connector, wherein the moving part has a main body and two arms. The two arms are on opposite sides of the main body and facing the direction of the connector, and are suitable for clamping these positioning structures. When the moving part slides relative to the connector and the two arms slide into the positioning structures, the moving part and the bottom plate are engaged with each other, so that the moving part is fixed on the bottom plate.

Based on the above, the present invention provides a fixing assembly that can fix the interface card on the motherboard, and when the fixing assembly is installed on the motherboard, the fixing assembly can be removed from the front of the motherboard, which is very convenient. On the other hand, when replacing interface cards of different lengths, users can replace interface cards of different lengths by sliding the moving member without removing the fixing assembly.

Please refer to FIG. 1A, FIG. 1B, FIG. 2A, and FIG. 2B. The present invention provides a fixing assembly 100, which is suitable for fixing an interface card 20 on a motherboard 10. The motherboard 10 has a plurality of fixing holes 12 and a connector 11. The fixing assembly 100 includes a bottom plate 110, a plurality of rivets 120, and a moving member 130. The bottom plate 110 is suitable for corresponding to the connector 11 and is disposed on the motherboard 10, and has a plurality of through holes 111 and a plurality of positioning structures 112, wherein the positioning structures 112 are symmetrically disposed on opposite sides of the bottom plate 110, and the through holes 111 correspond to the fixing holes 12, respectively. The rivets 120 are suitable for corresponding to the through holes 111, respectively, and are disposed in the fixing holes 12. The moving member 130 is slidably disposed on the bottom plate 110 relative to the connector 11. The moving member 130 has a main body 131 and two arms 132, wherein the two arms 132 are located at opposite sides of the main body 131 and face the direction of the connector 11, and are suitable for clamping these positioning structures 112. When the moving member 130 slides relative to the connector 11 and the two arms 132 slide into these positioning structures 112, the moving member 130 and the bottom plate 110 are engaged with each other, so that the moving member 130 is fixed on the bottom plate 110.

The fixing assembly 100 further includes a plurality of fasteners 150, which fasten the bottom plate 110 to the motherboard 10 through the rivets 120. Specifically, in the present embodiment, the number of the rivets 120 and the fasteners 150 is two. In other embodiments, the number of the rivets 120 and the fasteners 150 may be more than two, depending on the needs of the user. When the user wants to assemble the fixing assembly 100 to the motherboard 10 or remove the fixing assembly 100 from the motherboard 10, the fixing assembly 100 only needs to be fastened from the front of the motherboard 10 and the front of the bottom plate 110, and does not need to be fastened from the back of the motherboard 10.

When the interface card 20 is placed on the bottom plate 110, the moving member 130 slides relative to the bottom plate 110 and abuts against the interface card 20. At this time, the two arms 132 slide into the positioning structures 112, so that the moving member 130 is fixed on the bottom plate 110, and the interface card 20 is further fixed on the fixing assembly 100. In addition, the fixing assembly 100 further includes a heat sink 140, which is placed on the bottom plate 110 and is used for heat dissipation of the interface card 20.

The positioning structures 112 also have a plurality of positioning grooves 112a, which are arranged on the moving paths of the two arms 132 to provide a plurality of positioning points for the moving member 130. Each of the two arms 132 has a positioning block 132a, which is suitable for being accommodated in the positioning grooves 112a and mutually engaged with one of the positioning grooves 112a. Specifically, when the moving member 130 slides relative to the base plate 110, the positioning block 132a abuts against the opposite sides of the base plate 110 along with the arms 132. When the positioning block 132a on one side moves to one of the positioning grooves 112a, the positioning block 132a will be engaged in the positioning groove 112a. Correspondingly, the positioning block 132a on the other side is also engaged in the corresponding positioning groove 112a, so that the moving member 130 is fixed on the bottom plate 110 and does not slide relative to the bottom plate 110. On the other hand, in this embodiment, the two sides of these positioning grooves 112a are inclined surfaces, so that the positioning block 132a can be more easily guided into these positioning grooves 112a or slid out of these positioning grooves 112a.

Please continue to refer to Figures 2A and 2B. The main body 131 of the moving member 130 also has a fixed protrusion 131a. Correspondingly, one side of the interface card 20 has a groove 21, wherein the fixed protrusion 131a is suitable for interlocking with the groove 21 of the interface card 20. On the other hand, the other side of the interface card 20 is coupled to the connector 11. When the interface card 20 is to be fixed on the motherboard 10, the interface card 20 is first set on the bottom plate 110 and coupled to the connector 11, and then the moving member 130 is slid toward the direction of the connector 11, so that the fixed protrusion 131a is engaged in the groove 21, thereby making the moving member 130 and the interface card 20 engage with each other. In other words, the moving member 130 simultaneously engages the base plate 110 and the interface card 20 via the positioning block 132 a and the fixing protrusion 131 a , so that the interface card 20 is fixed on the fixing assembly 100 .

In this embodiment, the main body 131 further has a finger-receiving groove 131 b , and the user can push the moving member 130 through the finger-receiving groove 131 b to make the moving member 130 slide relative to the bottom plate 110 .

3A and 3B , the fixing assembly 100 further includes a plurality of protrusions 160, which are detachably disposed in the through holes 111 and protrude from the through holes 111 and the heat sink 140. When the thickness of the interface card 20 is relatively thin, the interface card 20 can be lifted by the protrusions 160, so that the bottom of the interface card 20 abuts against the protrusions 160, thereby lifting the interface card 20 to be coupled to the connector 11.

Please refer to FIG. 2A, FIG. 2B and FIG. 4. When assembling interface cards 20' of different lengths onto the motherboard 10, it is only necessary to slide the moving member 130 away from the connector 11 so that the fixed protrusion 131a is disengaged from the groove 21. At this time, the positioning block 132a will leave these positioning grooves 112a along with the moving member 130 so that the moving member 130 is no longer engaged with the base plate 110. Then, the original interface card 20 is pulled out from the connector 11, and the interface card 20' to be replaced is inserted. Finally, the moving member 130 is slid toward the connector 11 so that the fixed protrusion 131a is engaged with the groove 21' of the interface card 20'. At this time, the positioning block 132a will slide into another positioning groove 112a along with the moving member 130. Specifically, since the two sides of the base plate 110 have these positioning grooves 112a, and these positioning grooves 112a correspond to the length of the interface card 20', when replacing the interface card 20' of different lengths, it is only necessary to slide the movable member 130 to move the positioning block 132a to the corresponding positioning groove 112a, so that the movable member 130, the interface card 20' and the base plate 110 can be engaged with each other, thereby fixing the interface card 20' on the fixing assembly 100.

In summary, the present invention provides a fixing assembly that can fix the interface card on the motherboard, and when the fixing assembly is installed on the motherboard, the fixing assembly can be removed from the front of the motherboard, which is very convenient. On the other hand, when replacing interface cards of different lengths, users can replace interface cards of different lengths by sliding the moving member without removing the fixing assembly.
