Line and sidewall portion 132 between；That is, the top 135 of fastener 130 is staggered in the company of multiple third through-holes 138
Line.In this way, which the second heat dissipation is protruded into the top 135 that can avoid fastener 130 during installing radiating subassembly 100
The fifth hole 158 of second through-hole 128 of part 120 and the second heat dissipation cushion 150 and the damage for causing expansion card 200.
In order to become apparent from present the present embodiment radiating subassembly 100 each component relative configuration relationship, below for
The process that the first expansion card 200A is set in the installing of radiating subassembly 100 carries out exemplary illustrated.Fig. 7 A to Fig. 7 D is the radiating subassembly of Fig. 1
The assembling flow path figure being configured on expansion card 200.
Please refer to Fig. 7 A, firstly, by the first expansion card 200A configuration the first radiating piece 110 and the second radiating piece 120 it
Between, and make the first radiating piece 110 two group of first recess 115 be aligned the second radiating piece 120 two group of first limiting section 122 with into
The row first stage is to group (in a direction z).In the first stage to group during, the first limiting section 122 of the second radiating piece 120
Protrude into the first recess 115 of the first radiating piece 110.Certainly, in the present embodiment, the first expansion card 200A and the first radiating piece
The first heat dissipation cushion 140 (being illustrated in Fig. 3), the first expansion card 200A and the second radiating piece are optionally provided between 110
The second heat dissipation cushion 150 is optionally provided between 120.
Special one is mentioned that, the second radiating piece 120 may also include third limiting section 124, installs in the first expansion card 200A
During between the first radiating piece 110 and the second radiating piece 120, extending the circuit board 210 of the first expansion card 200A
Side be upwardly away from a side 210a of pin 212 against the second radiating piece 120 third limiting section 124 (referring to figure
7B).In this way, which the first expansion card 200A for being installed with radiating subassembly 100 (is shown in the connector 310 of insertion motherboard 300
In Fig. 5) during, it can avoid the first expansion card 200A because mistake occurs for the Force feedback and radiating subassembly 100 of connector 310
Position and the damage for causing the first expansion card 200A (or heat dissipation cushion).In the present embodiment, the quantity of third limiting section 124 is with two
For a, but the quantity of third limiting section 124 is not limited thereto system.
Fig. 7 B is please referred to, then, three groups of third clamping parts 133 of fastener 130 and the 4th clamping part 134 are respectively aligned to
Three group of second recess 116 of the first radiating piece 110 is to carry out second stage to group (in a direction z).In second stage to group
In the process, the third clamping part 133 of fastener 130 and the 4th clamping part 134 are respectively protruding into corresponding the one of the first radiating piece 110
In the second recess 116 of group.
Fig. 7 C is please referred to, then, fastener 130 is moved along direction Y, makes the third clamping part 133 of fastener 130
(being illustrated in Fig. 7 B) and the 4th clamping part 134 slide into the first clamping part 111 and the 5th clamping part of the first radiating piece 110 respectively
Between 113 and between the second clamping part 112 and the 6th clamping part 114 of the first radiating piece 110, to snap into the first radiating piece
110 the first clamping part 111 and the second clamping part 112.
It is noted that by Fig. 7 D it is found that when the first radiating piece 110, the first expansion card 200A and the second radiating piece 120
When being snapped the fixation of part 130 jointly, the third clamping part 133 (being illustrated in Fig. 7 B) of fastener 130 and the 4th clamping part 134 difference
Against one group of first limiting section 122 of the second radiating piece 120.In other words, the first limiting section 122 of the second radiating piece 120 is gone back
Can fixing card fastener 130 and the first radiating piece 110 relative position.
In conclusion the first radiating piece and the second radiating piece of the radiating subassembly of the utility model are suitable for configuration in expansion card
Two sides, the first radiating piece and the second radiating piece can effectively reduce the running temperature of expansion card, and then strengthen the operation of expansion card
Efficiency.In addition, in the present invention, the second radiating piece is between the first radiating piece and fastener, the third card of fastener
Buckle and the 4th clamping part are respectively slidably fastened on the first clamping part and the second clamping part of the first radiating piece, and by
One radiating piece and the second radiating piece are fixed on the two sides of expansion card.In addition, the first limit that radiating subassembly passes through the second radiating piece
Portion protrudes into the first recess of the first radiating piece, can avoid the first radiating piece, expansion card and the second radiating piece and is snapping into fastener
Sliding process in misplace, be effectively reduced expansion card damage risk.
Although the utility model is disclosed as above with embodiment, so it is not intended to limit the utility model, any affiliated
Those of ordinary skill in technical field, without departing from the spirit and scope of the utility model, when can make a little variation and profit
Decorations, therefore the protection scope of the utility model is subject to view appended claims institute defender.
