As can be seen from the above, the first fixing bracket 7 may also be composed of the second fixing bracket 8 and the second connector 4.

The utility model discloses a fixed bolster and have electron device beneficial effect of this fixed bolster as follows:

1) one of the first supporting portion 716 and the second supporting portion 717 of the first fixing bracket 7 and the first fixing portion 72 are located on the same side of the installation side surface 521 in the transverse direction, and the other of the first supporting portion 716 and the second supporting portion 717 and the first fixing portion 72 are located on both sides of the installation side surface 521 in the transverse direction, it can be seen that when the expansion card 5 is subjected to the gravity of the heat sink 6 and is tilted to the side away from the first fixing portion 72 in the transverse direction, the first supporting portion 716 or the second supporting portion 717 located on the different side from the installation side surface 521 from the first fixing portion 72 can provide a supporting force to the extension portion 52 in the lower direction of the extension portion 52 to avoid the expansion card 5 being forced to be excessively tilted to one side, and the first fixing portion 72 is subjected to the first supporting portion 716 and the second supporting portion 717 located on both sides of the installation side surface 521 in the transverse direction The supporting portion 717 provides a stable supporting function, and the first supporting portion 716 and the second supporting portion 717 can reduce the degree of bending of the first fixing bracket 7 toward the heat sink 6 in the transverse direction.

2) Since the first supporting portion 716 and the first fixing portion 72 are located on the same side of the mounting side 521 in the lateral direction, and the first supporting portion 716 extends beyond the first fixing portion 72 toward a side away from the mounting side 521 in the lateral direction, the second supporting portion 717 extends beyond the extending portion 52 in the lateral direction away from the first fixing portion 72, it is understood that the first and second supporting portions 716 and 717 span a greater distance in the lateral direction than the first fixing portion 72, the first fixing bracket 7 can be more stably disposed on the main board 2, that is, the first supporting portion 716 and the second supporting portion 717 are disposed at two sides of the bottom of the first fixing portion 72 in the transverse direction, so as to apply two supporting forces to the first fixing portion 72, the degree to which the first fixing bracket 7 is bent in the lateral direction toward the heat sink 6 side can be further reduced.

3) Since the second supporting portion 717 is located below the heat dissipating device 6 in the vertical direction, it can be seen that the protruding portion 714 is also located below the heat dissipating device 6 in the vertical direction, when the expansion card 5 is bent toward one side of the heat dissipating device 6 due to the gravity of the heat dissipating device 6, the heat dissipating device 6 will abut downward to the protruding portion 714 along with the bending of the expansion card 5, so as to further reduce the degree of bending deformation of the expansion card 5 and the first fixing bracket 7 due to the gravity of the heat dissipating device 6. Similarly, the second connector 4 is located below the heat dissipation device 6, so that the heat dissipation device 6 can be abutted to the second connector 4 downward along with the bending of the expansion card 5, thereby further reducing the degree of bending deformation of the expansion card 5 and the second fixing bracket 8 under the action of the gravity of the heat dissipation device 6.

4) The two first side plates 73 connect the first fixing portion 72 and the first base portion 71, so that the connection strength between the first fixing portion 72 and the first base portion 71 is enhanced, the first fixing support 7 is not prone to stress fracture, and the degree of bending deformation of the first fixing support 7 towards one side of the heat dissipation device 6 can be further prevented.

5) The two second side plates 83 are connected to the second fixing portion 82 and the second base portion 81, so that the connection strength between the second fixing portion 82 and the second base portion 81 is enhanced, the second fixing support 82 is not prone to stress fracture, and the degree of bending deformation of the second fixing support 8 towards one side of the heat dissipation device 6 can be further prevented.

6) A part of the second connector 4 is accommodated in the positioning portion 84, the first limiting surface 41 and the second limiting surface 42 are both accommodated in the positioning portion 84, the first limiting surface 41 is disposed facing the second fixing bracket 8 in the transverse direction, and the second limiting surface 42 is disposed facing the second fixing bracket 8 in the vertical direction, at least one of the first limiting surface 41 and the second limiting surface 42 is used for limiting the second fixing bracket 8 from being excessively bent towards one side of the second connector 4, so as to fully utilize the original second connector 4 on the motherboard 2, and effectively limit the second fixing bracket 8 from being excessively bent towards one side of the second connector 4.

7) The second connector 4 is arranged in alignment with the second fixing bracket 8 in the lateral direction, and the second fixing bracket 8 is provided with the relief portion 84 that mates with the second connector 4, it is known that the second connector 4 and the second fixing bracket 8 span a larger distance in the lateral direction than the second fixing portion 82, the second fixing bracket 8 can be more stably disposed on the main board 2, that is, the second connector 4 and the third supporting portion 811 are disposed at two lateral sides of the bottom of the second fixing portion 82, and apply two supporting forces to the second fixing portion 82, the degree to which the second fixing bracket 8 is bent in the lateral direction toward the side of the heat sink 6 can be further reduced, it is understood that the second fixing bracket 8 and the second connector 4 are coupled to correspond to the first fixing bracket 7.

8) The positioning element 93 and the locking element 94 of the third locking component 9c fix the second fixing bracket 8 on the main board 2 and fix the main board 2 on the housing 1, so that the third locking component 9c is used doubly and components are saved.

9) The second portion 712, which is thicker than the first portion 711, is disposed on the first fixing bracket 7, so as to increase the strength of the first base portion 71 of the first fixing bracket 7, and the third locking component 9c disposed on the second portion 712 can prevent the third locking component 9c from being disposed on the first portion 711, which has a weaker strength, and thus, the third locking component cannot provide a stable and effective supporting force when the first fixing bracket 7 is bent under a stress.

The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all the equivalent technical changes using the description and drawings of the present invention are included in the scope of the present invention.
