Abstract

An improved structure of clamping piece for fixing seat of heat sink is prepared as setting a pull piece extending outward at external end of one arm plate of clamping piece, pulling pull piece to release clamping slot at one end of clamping piece from clamping block of fixing seat when heat sink is to be dismounted, then easily taking down clamping piece for replacing or maintaining heat sink conveniently.

Description

The improved structure of the clip of heat sink fixing seat

The utility model relates to an improved structure of a clip of a heat sink fixing seat, in particular to a clip device for clamping a heat sink on a fixing seat, which can easily pull the pull tab to remove the clip and disassemble the heat sink. chip replacement.

According to, the general traditional heat sink fixing seat, (as shown in Figure 3 ), is on the integrated circuit board (PC board) 100, and the two fixing seats 200 are fixed on the integrated circuit board 100 with screws 300 first. , and then insert the heat sink 400 between the two fixing seats 200. In order to prevent the heat sink 400 from loosening, the general industry uses the clip 500 to clamp the heat sink 400 on the fixing seat 200, wherein the clip 500 is a The equal-arm clamping device uses the clip frame 501 in the middle to be sleeved on the obliquely tapered block 201 in the center of the fixing seat 200, and then uses the slots 502 on the two arms of the clip 500 to be clamped on the fixing seat respectively. 200 on both sides of the obliquely tapered blocks 202, and use the baffle 503 inside the center of the fixing seat 200 to clamp the heat sink 400 on the fixing seat 200;

Although the above-mentioned existing clip 500 can firmly clamp the heat sink 400 on the fixing seat 200, when it is desired to remove the heat sink 400 for replacement or maintenance, it is not easy to directly open the clip 500 with bare hands, but must use a tool. It is quite troublesome to pry open the clip 500 to take off the heat sink 400 .

The purpose of this utility model is an improved structure of the heat sink fixing seat clip that can be easily removed to facilitate the disassembly of the heat sink for replacement and maintenance.

In order to achieve the above object, the utility model takes the following design scheme:

An improved structure of the clip of a heat sink fixing seat is a heat sink inserted between two fixing seats on an integrated circuit board. The clip frame in the middle of the clip can be clamped on the obliquely tapered block in the middle of the fixed seat, the block inside the clip can also clamp the heat sink, and the slots on the arm plates at both ends of the card can be clipped on the fixed block respectively. On the obliquely tapered blocks on both sides of the seat, it is characterized in that:

The outer end of one of the arm plates of the clip is provided with a pull-tab that extends outward. When the heat sink is to be removed, the user only needs to pull the pull-tab with fingers to loosen the slot at one end of the clip from the block of the fixing seat. The clips can be easily removed to disassemble the heat sink.

Fig. 1 is the exterior view of the utility model.

Fig. 2 is the front view of the utility model.

Fig. 3 is an appearance diagram of an existing product.

Please refer to Fig. 1 and Fig. 2, the utility model is fixed with two fixing seats 2 on the integrated circuit board (PC board) 1, and the two fixing seats 2 can be inserted into the cooling fins 3, and the cooling fins 3 are parallel to each other. The clips 4 at both ends can be used to clamp on the fixed seat 2. The middle part of the clip 4 has a clip frame 41, which can be clamped on the obliquely tapered block 21 in the middle of the fixed seat 2. The inner side has a The baffle 42, the baffle 42 can clamp the heat sink 3, and the arm plates 43 at both ends of the clip 4 have a slot 431 respectively, and the slot 431 can be respectively clamped on both sides of the fixing seat 2 to form an oblique cone On the block 22 of the shape; its clip 4 is a sheet body with two arms of equal length, and its clip frame 41 is therefore located in the center, and it is provided with the block 21 in the center of the fixing seat 2, and one of the outer ends of the arm plate 43 is provided with a The pull-tab 432 extending outward, when the clip 4 securely fixes the cooling fin 3 on the fixed base 2, if you want to disassemble the cooling fin 3 for replacement or maintenance (see Figure 2), you only need to use your fingers Pull the pull piece 432, so that the slot 431 at one end of the clip 4 is loosened from the catch of the block 22 of the fixed seat 2, so that the clip 4 can be easily removed without using other tools, so that it can be disassembled heat sink 3.

The utility model has the advantages that: when dismantling the heat sink, the user only needs to pull the pull piece with fingers, so that the slot at one end of the clip is loosened from the catch of the fixing block, and the clip can be easily removed , easy to disassemble the heat sink for replacement or maintenance.

Claims (1)

1, a kind of improvement structure of fin holder intermediate plate, it is the fin of being planted between two holders on the integrated circuit board, but this fin is the intermediate plate of mat two ends distinguishes clamping on holder, but wherein on the fixture block of the tilted conical in the middle of holder of the clamp frames clamping in the middle of the intermediate plate, but the catch of intermediate plate inboard and clamping are lived fin, draw-in groove on the arm plate of card two ends can fix respectively on the fixture block of holder both sides tilted conical, it is characterized in that:

A wherein arm plate outer end of intermediate plate is provided with an outward extending pulling-on piece.
