[0030] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0031] See also Figures 1 to 8According to an embodiment of the utility model, a clamping structure is provided, comprising: a housing 1; a circuit board 2; the circuit board 2 comprising a first mounting surface and a second mounting surface for mounting components; the first mounting surface and the second mounting surface being arranged opposite to each other; an electrical component 3, the electrical component 3 being connected to the circuit board 2; a clamping component 4, the clamping component 4 being connected to the electrical component 3; a clamping structure 5, the clamping structure 5 being connected to the clamping component 4, so as to fix the electrical component 3 between the clamping component 4 and the housing 1 by squeezing the clamping component 4. With the above arrangement, during installation, the first mounting surface is the front side, and the second mounting surface is the back side. The clamping structure of the electrical component 3 utilizes the gap between the back side of the circuit board 2 and the housing 1, making use of the originally useless space, while eliminating the heat dissipation fins on the front side of the circuit board 2, saving a lot of space, reducing the size of the circuit board 2, improving the integration of component installation, and solving the technical problem of insufficient circuit board space in electronic products in related technologies.

[0032] In the compression structure of this embodiment, see Figure 4 The pressing member 4 is disposed between the circuit board 2 and the electrical component 3; the pressing structure 5 includes a fixing member 51 that passes through the circuit board 2 and presses against the electrical component 3. Thus, the pressing member 4 passes through the hole in the circuit board 2 and then presses against the electrical component 3, thus preserving the structure of the circuit board 2 and saving space on the circuit board 2.

[0033] See also Figure 2 In the compression structure of this embodiment, the compression structure 5 includes a mounting assembly 52, which is connected to the housing 1 and is connected to the fixing member 51. In this way, the fixing member 51 is fixed to the housing 1 through the mounting assembly 52, so that the fixing member 51 is securely installed.

[0034] See also Figure 2 In the clamping structure of this embodiment, the mounting assembly 52 includes: a fixing column 521, the fixing column 521 is connected to the shell 1; a fixing plate 522, the fixing plate 522 is connected to the end of the fixing column 521 away from the shell 1; and the fixing plate 522 is connected to the fixing component 51.

[0035] In the compression structure of this embodiment, see Figure 2 The circuit board 2 is provided with a mounting through hole 21, and the fixing post 521 is provided through the mounting through hole 21. In this way, on the one hand, the position setting of the fixing post 521 is facilitated, and on the other hand, the fixing post 521 can play a role in limiting the position of the circuit board 2, thereby facilitating the installation of the circuit board 2.

[0036] See also Figure 2In the clamping structure of this embodiment, the fixing post 521 is provided with a connecting through-hole having an internal thread. The clamping structure also includes a fastener 6 having an external thread that mates with the internal thread in the connecting through-hole. The fastener 6 is inserted through the fixing plate 522 and the fixing post 521 to connect the fixing plate 522 to the fixing post 521. The provision of the fastener 6 facilitates installation and removal of the fixing plate 522.

[0037] Example 1

[0038] In the compression structure of this embodiment, see Figure 4 The pressing part 4 is provided with a fixing through hole, in which an internal thread is provided; the fixing part 51 is provided with an external thread that matches the internal thread in the fixing through hole. In this way, the fixing part 51 passes through the pressing part 4 and directly contacts the electrical component 3, thereby improving the pressing effect.

[0039] Example 2

[0040] In the clamping structure of this embodiment, different from the first embodiment, a threaded hole is provided on the fixing plate 522, and an external thread matching the threaded hole is provided on the fixing component 51. The fixing component 51 directly abuts against the clamping component 4, and the electrical component 3 is clamped by the clamping component 4, so that the structure of the electrical component 3 can be protected.

[0041] See also Figure 5 In the clamping structure of this embodiment, there are multiple electrical components 3; there are multiple clamping components 4, and the multiple clamping components 4 are arranged in a one-to-one correspondence with the multiple electrical components 3; and / or, the clamping component 4 is a plate-shaped structure.

[0042] Specifically, multiple pressing components 4 and multiple electrical components 3 are provided to save more space and improve heat dissipation efficiency. The pressing component 4 is provided as a plate-like structure to increase the contact area of ​​the pressing component 4, protect the structure, and improve the pressing effect.

[0043] See also Figure 2 In the compression structure of this embodiment, a heat sink 7 is attached to the inner wall surface of the housing 1, one end of the electrical component 3 is attached to the heat sink 7, and the other end of the electrical component 3 is attached to the compression component 4. In this way, the heat dissipation efficiency of the structure can be improved.

[0044] The electrical device of this embodiment includes a compression structure, which is the compression structure described above. The electrical device of this embodiment employs the compression structure described above, thereby resolving the issue of components and heat sinks occupying a large area on the circuit board, reducing the overall size of the circuit board. This also addresses the issue of insufficient heat dissipation in high-power and high-device density environments.

[0045] The description of the compression structure of this embodiment is as follows:

[0046] This embodiment provides a compacting structure for MOS tubes. This structure is simple. The fixing column 521, the fixing plate 522, and the compacting component 4 on the housing 1 can be used to compact the MOSFET device (i.e., the electrical component 3 of this embodiment) onto the housing 1. This saves space on the circuit board 2 and utilizes the large area of ​​the housing 1 to greatly improve the heat dissipation efficiency of the MOSFET. The specific implementation scheme is as follows:

[0047] like Figure 5 This is a front view of the clamping structure. You can see that there are four screws on the fixing plate 522. The clamping structure consists of the following parts: the fixing plate 522, the clamping component 4, the fixing column 521 and the fixing screws. The clamping component 4 is embedded in the gap between the MOSFET and the circuit board 2 before the circuit board 2 is installed into the machine housing 1. The circuit board 2 is then installed into the housing 1, and the fixing column 521 passes through the hole reserved on the circuit board 2 and protrudes above the circuit board 2. The fixing plate 522 is fixed to the fixing column 521 with two screws, using Figure 6 The two through holes in the fixing plate 522 are slightly larger than the major diameter of the screw and smaller than the outer diameter of the screw head. Therefore, when the screw is tightened down on the fixing column 521, the screw head can press the fixing plate 522 onto the fixing column 521. After the fixing plate 522 is installed, the other two screws are screwed into the two screw holes on the fixing plate 522, first passing through the reserved holes on the circuit board 2, and then tightening the clamping component 4 pre-clamped between the MOSFET and the circuit board 2. While the clamping component 4 is pressed down by the screw, it presses the MOSFET onto the machine housing 1, so that the heating surface of the MOSFET is in close contact with the machine housing 1. After the MOSFET is installed on the back of the circuit board 2, it effectively saves the device area on the front of the circuit board 2, which can further reduce the area of ​​the circuit board 2 and further enrich the functions of the circuit board 2 of the same area. At the same time, the MOSFET relies on the larger area of ​​the housing to dissipate heat, which significantly improves the efficiency of heat dissipation, extends the service life of the device, and ensures the normal operation of the machine function.

[0048] In summary, the compression structure of this embodiment can effectively save the use area of ​​the circuit board 2, and at the same time has the advantage of improving the heat dissipation efficiency, saving the economic cost of using additional heat dissipation devices, and has great promotion value.
