DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0030] Example:

[0031] The embodiment of the utility model provides an ultra-thin anti-bending positioning circuit board, which is intended to solve the technical problem in the prior art that the circuit board is prone to warping during use.

[0032] See also Figure 1-Figure 9 , the utility model provides a technical solution:

[0033] First, see Figure 1 , Figure 2 and Figure 4 , an ultra-thin anti-bending positioning circuit board, including a bottom plate 1, an empty slot 2 is opened inside the bottom plate 1, a circuit board 4 is installed on one side of the bottom plate 1 where the empty slot 2 is opened, and buffer springs 101 are evenly connected at the corners of the bottom plate 1. When the user uses the circuit board 4, if a bump occurs, the buffer spring 101 can prevent the circuit board 4 from warping due to the bump, and can also reduce the circuit board 4 from breaking due to the bump. A heat sink 201 is installed inside the empty slot 2, and an insulating gasket 202 is installed on the side of the heat sink 201 away from the empty slot 2. The circuit board 4 will generate a certain amount of heat when working for a long time. At this time, the heat sink 201 can help the circuit board 4 dissipate the heat outward to avoid excessive temperature affecting the service life of the circuit board 4. At the same time, because the heat sink 201 cannot be used directly against the circuit board 4, the insulating gasket 202 in the middle can help the heat sink 201 without affecting the use effect of the circuit board 4.

[0034] For further information, see Figure 1 , Figure 2 and Fig. 9 , positioning blocks 3 are connected to both sides of the bottom plate 1, and a fixed card slot 301 is opened inside the positioning block 3. Open slots 401 are opened at the positions of the positioning blocks 3 on both sides of the circuit board 4. When installing, the user can align the circuit board 4 with the positioning block 3 through the open slots 401 and press it to quickly position the circuit board 4, which increases the speed and convenience of operation.

[0035] Among them, see Figure 1 , Figure 3 , Figure 5 ,、 Figure 7 and Fig. 9 , a fixing frame 5 is installed on the side of the positioning block 3 away from the base plate 1, and the two ends of the fixing frame 5 are connected to the limiting frames 501. The fixing frame 5 and the limiting frame 501 are designed as an integrated structure. The internal size structure of the fixing frame 5 matches the external size structure of the base plate 1. First reinforcement holes 5011 are evenly opened at the surface corners of the limiting frame 501, and second reinforcement holes 102 are opened at the positions of the base plate 1 corresponding to the first reinforcement holes 5011. The user installs the heat sink 201, the insulating gasket 202 and the circuit board 4 on the base plate 1, and then covers the fixing frame 5 and the limiting frame 501. The limiting frame 501 can limit the internal insulating gasket 202 so that the insulating gasket 202 will not fall off during movement. At the same time, the limiting frame 501 also protects the internal circuit board 4. After the limiting frame 501 and the base plate 1 are connected by screws through the first reinforcement holes 5011 and the second reinforcement holes 102, the external firmness is also increased, so that the fixing frame 5 will not easily fall off due to the impact of external force.

[0036] For further information, see Figure 1 , Figure 3 , Figure 6 , Figure 7 and Figure 8 , the position of the fixed frame 5 corresponding to the positioning block 3 is connected to a connecting plate 502, and the position of the connecting plate 502 corresponding to the fixed card slot 301 is matched with a fixing buckle 5021. When the user installs, the connecting plate 502 is pressed against the positioning block 3, and the fixing buckle 5021 follows the connecting plate 502 downward into the fixing card slot 301, fixing the fixing frame 5 on the top of the circuit board 4. At this time, the internal components become a whole, and a card slot 5022 is opened inside the fixing buckle 5021, and both sides of the card slot 5022 are connected to the card block 5023. The block groups 5023 are connected by springs 5024. The block 5023 is triangular in design. Both sides of the block 5023 are connected with raised blocks. The internal structure size of the slot 5022 matches the external structure size of the block 5023. When the fixed buckle 5021 enters the fixed slot 301, the blocks 5023 on both sides are squeezed into the slot 5022. When it then enters the fixed slot 301, the rebound force of the spring 5024 bounces the block 5023 back to the outside of the fixed slot 301. It is also very convenient for the user to disassemble the fixed frame 5 later.

[0037] For further information, see Figure 1 , Figure 3 , Figure 5 A fixing plate 6 is connected to the connection between the fixing frame 5 and the limiting frame 501. A first fixing hole 601 is opened on the surface of the fixing plate 6. A second fixing hole 402 is opened at the position of the circuit board 4 corresponding to the first fixing hole 601. The user reinforces the circuit board 4 by screwing the fixing plate 6 to prevent the circuit board 4 from warping and completely fix the fixing frame 5 and the circuit board 4.

[0038] In addition, it should be supplemented according to the above embodiments that the circuit board 4 is a prior art, and its internal working principle and operation process will not be described in detail here.

[0039] The working process of the utility model is as follows: when installing the circuit board 4, first put the heat sink 201 into the empty slot 2, then put the insulating gasket 202 on the heat sink 201, and then install the circuit board 4, align the open slot 401 with the positioning block 3 and press it, fix the circuit board 4 and quickly position the circuit board 4 on the base plate 1, then press the connecting plate 502 on the fixing frame 5 against the fixing slot 301, at this time, the fixing buckle 5021 follows the connecting plate 502 downward into the fixing slot 301, fixes the fixing frame 5 above the circuit board 4, and at the same time, the limiting frame 501 limits the internal insulating gasket 202, and then the user screws the fixing frame 5 and the circuit board 4 together through the fixing plate 6, and after the reinforced connection is completed, screw connection is performed through the first reinforcement hole 5011 on the limiting frame 501 and the second reinforcement hole 102 on the base plate 1.

[0040] The entire operation process is simple and convenient. Compared with the existing anti-bending positioning circuit board, the utility model can effectively reduce the technical problem of warping of the circuit board during use through design.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
