Description

Technical Field

[0001] This utility model belongs to the field of power module technology, and specifically relates to a power module structure. Background Technology

[0002] Power module parameters are an indispensable part of modern electronic equipment, playing a crucial role in the stability and performance of the device. Widely used in various industrial automation sectors, power modules offer a variety of functions, such as voltage conversion, current regulation, and overload protection, making them increasingly popular.

[0003] Currently, power modules typically have perforated openings in their casings to ensure heat dissipation, supplemented by fans. However, during prolonged use, dust, fibers, and other debris from the air can easily be blown into the power module's interior. This dust not only hinders heat dissipation for the components themselves but also affects device performance. In such cases, maintenance personnel often need to disassemble the power module's casing and clean the interior using brushes and other tools, and remove the surface dust with a blower. For power modules without potting compound, cleaning the gaps between components is often difficult, making the process cumbersome and complex. Utility Model Content

[0004] To address the shortcomings of existing technologies, a power module structure is provided to solve the problems of dust accumulation in power modules leading to performance degradation and cleaning difficulties.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A power module structure, comprising:

[0006] A base plate is used to mount power devices. The two sides of the base plate are bent upward to form side plates, and heat dissipation holes are provided on the side plates.

[0007] The top plate is detachably fitted onto the bottom plate, forming an installation space with the bottom plate and the side plate. The top plate has heat dissipation holes.

[0008] Dustproof components are detachably fitted to the inner walls of the top plate and the side plate;

[0009] Wiring terminals are provided on the base plate.

[0010] Compared with existing technologies, the above technical solutions have the following beneficial effects:

[0011] The dustproof component inside the top plate fits snugly against the heat dissipation holes on the top plate and side plate, preventing external dust and fibers from entering the power module through the heat dissipation holes. This avoids dust adhering to internal components and causing performance degradation. In addition, the top plate and bottom plate are detachable, so when the dustproof component needs to be replaced, only the top plate needs to be removed for replacement, making the operation convenient.

[0012] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0013] In one embodiment, the top plate includes an insert plate formed by bending the tail end downward, and the top plate has side edges that are bent downward on both sides and cover the side plates.

[0014] The bottom plate is bent upward at its tail end to form a tail plate, and a slot for engaging the insert plate is formed between the tail plate and the end of the side plate.

[0015] A detachable connection is achieved by inserting the insert plate into the slot formed by the tail plate and the side plate. At the same time, the side edges of the top plate can cover the top of the side plate, making the connection between the top plate and the bottom plate convenient and detachable, and also able to be firmly connected.

[0016] In one embodiment, a front baffle is hinged to the front end of the top plate, a fixing block is provided at the front end of the side plate, and a fastener connected to the fixing block is connected through the side of the front baffle.

[0017] The front panel and the top panel are connected by a hinge. The dustproof part inside the installation space can be seen by flipping the front panel, and the dustproof part can be pulled out for replacement. In addition, the fasteners on the front panel and the fixing blocks on the side panels work together to achieve a quick fastening connection. Together with the plug at the rear end, it provides a good fastening effect while ensuring quick disassembly.

[0018] In one embodiment, the base plate is provided with two first limiting strips, which are spaced apart from the side plate to form a first limiting groove for engaging the two sides of the dustproof component.

[0019] The first limiting groove is used to engage the side of the dustproof component, ensuring that the dustproof component can fit snugly against the inner wall of the side panel.

[0020] In one embodiment, two second limiting strips are suspended on the top inner side of the top plate component, and a second limiting groove is formed between the second limiting strips and the top wall and side wall of the top plate to allow the dustproof component to pass through.

[0021] The second limiting strip is used to create a gap between itself and the top and side walls, allowing the dustproof component to bypass the second limiting strip. At the same time, the second limiting strip restricts the dustproof component, attaching it to the inner top surface and inner side wall surface of the top plate component.

[0022] In one embodiment, the distance between the second limiting strip and the side plate is the same as the distance between the first limiting strip and the side plate.

[0023] In one embodiment, a connecting block is connected to the second limiting strip, the connecting block being connected to the end of the second limiting strip and the top plate member, and the second limiting strip being located at the end near the tail plate.

[0024] The second limit strip is suspended by a connecting block located at the tail end, which facilitates the direct removal and installation of the dustproof parts when the front baffle is opened.

[0025] In one embodiment, a wire clamping device is provided on the base plate, and the wire clamping device is located on the side of the terminal block away from the mounting space.

[0026] In one embodiment, the wire clamping device includes:

[0027] The base has several first grooves that correspond one-to-one with the wiring terminals;

[0028] A pressure strip, wherein a second groove corresponding to the first groove is provided on the pressure strip;

[0029] Fastening bolts are located at both ends of the pressure strip and are used to fasten the pressure strip to the base. Attached Figure Description

[0041] Example

[0042] like Figure 1-3 As shown, the power module structure provided by this utility model includes: a base plate 1, a top plate 3, a dustproof component 5, and wiring terminals 6.

[0043] The base plate 1 is used to set up power devices, such as mounting and connecting circuit boards. The two sides of the base plate 1 are bent upward to form side plates 2. The side plates 2 are provided with heat dissipation holes 4. The top plate 3 is detachably covered on the base plate 1, forming an installation space with the base plate 1 and the side plates 2. The top plate 3 is provided with heat dissipation holes 4. The wiring terminal 6 is set on the base plate 1 and is located at the front end of the base plate 1.

[0044] The dustproof component 5 is detachably attached to the inner wall of the top plate 3 and the side plate 2. The dustproof component 5 can be made of sheet material such as a filter screen, which is convenient to attach to the inner wall of the top plate 3 and the side plate 2.

[0045] The dustproof component 5 inside the top plate 3 fits into the heat dissipation holes 4 on the top plate 3 and the side plate 2, preventing external dust, lint, and fibers from entering the power module through the heat dissipation holes 4. This avoids dust adhering to internal components and causing performance degradation. At the same time, the top plate 3 and the bottom plate 1 are detachable. When the dustproof component 5 needs to be replaced, only the top plate 3 needs to be removed for replacement, which is convenient.

[0046] Specifically, the top plate 3 includes an insert plate 7 formed by bending the tail end downwards. The top plate 3 has side edges 8 formed by bending the two sides downwards and covering the side plate 2. After the top plate 3 is installed in place, the side edges 8 cover the top outer side of the side plate 2. The bottom plate 1 has a tail plate 9 formed by bending the tail end upwards. A slot 10 for engaging the insert plate 7 is formed between the tail plate 9 and the end of the side plate 2. The slot 10 and the insert plate 7 are interference fit to ensure the stability of the insert plate 7 when inserted into the slot 10.

[0047] The insert plate 7 is inserted into the slot 10 formed by the tail plate 9 and the side plate 2 to achieve a detachable connection. At the same time, the side edges 8 on both sides of the top plate 3 can cover the top of the side plate 2, making the connection between the top plate and the bottom plate 1 convenient and detachable, and also able to be firmly connected.

[0048] To facilitate the disassembly and assembly of the dustproof component 5, a front baffle 11 is hinged to the front end of the top plate component 3. The front baffle 11 at least partially blocks the openings at the front ends of the top plate component 3, the side plate 2, and the bottom plate 1. The top edge of the front baffle 11 is connected to the front end of the top plate component 3 by a hinge, allowing the front baffle 11 to be folded upwards and opened. A fixing block 12 is provided at the front end of the side plate 2, and a through hole is provided on the fixing block 12. A fastener 13 connected to the fixing block 12 is passed through the side of the front baffle 11. After the fastener 13 passes through the through hole on the side of the front baffle 11 and is fastened, the front baffle 11 is fastened to the front opening, thus playing a fixing role.

[0049] The front baffle 11 is connected to the front end of the top plate 3 by a hinge. The dustproof part 5 inside the installation space can be seen by flipping the front baffle 11, and the dustproof part 5 can be pulled out for replacement. In addition, the fastener 13 on the front baffle 11 and the fixing block 12 on the side plate 2 cooperate to achieve a quick fastening connection. It cooperates with the plug at the rear end to play a good fastening role, while ensuring quick disassembly.

[0050] On the one hand, the dustproof component 5 can be folded into a single piece and attached to the inside of the top plate 3 and the side plate 2; on the other hand, the dustproof component 5 can also be made of multiple pieces, such as three pieces, and attached to the inner walls of the top plate 3 and the two side plates 2 respectively to block the heat dissipation holes 4.

[0051] To facilitate the fixing of the dustproof component 5, two first limiting strips 14 are provided on the base plate 1. The first limiting strips 14 are spaced apart from the side plate 2 to form a first limiting groove 15, which is used to engage the two sides of the dustproof component 5. By engaging the sides of the dustproof component 5 with the first limiting groove 15, it is ensured that the dustproof component 5 can fit against the inner wall of the side plate 2. When the dustproof component 5 is a whole piece, the two sides of the dustproof component 5 are engaged in the groove 10. When the dustproof component 5 is multiple pieces, the bottom edge of one dustproof component 5 is engaged in the groove 10.

[0052] Furthermore, such as Figure 3 As shown, two second limiting strips 16 are suspended on the top inner side of the top plate 3. The second limiting strips 16 are spaced apart from the top wall and side wall of the top plate to form a second limiting groove 17 for the dustproof component 5 to pass through. The second limiting strips 16 are spaced apart from the top wall and side wall, so that the dustproof component 5 can bypass the second limiting strips 16. At the same time, the second limiting strips restrict the dustproof component 5, and attach the dustproof component 5 to the inner top surface and the inner side wall surface of the top plate 3. When the dustproof component 5 is a whole piece, the middle part of the dustproof component 5 is bent and attached to the two corners of the top plate 3 through the two second limiting strips 16. When the dustproof component 5 is multiple pieces, the second limiting strips 16 restrict the two sides of the dustproof component 5 attached to the top plate 3 and restrict the top edges of the two dustproof pieces attached to the side plate 2.

[0053] To ensure that the dustproof component 5 fits more closely with the top plate component 3 and the side plate 2, the distance between the second limiting strip 16 and the side plate 2 is consistent with the distance between the first limiting strip 14 and the side plate 2. This allows the dustproof component 5 to fit more closely with the corners when folded or limited at the corners on both sides of the top plate, and thus fits more closely with the side plate 2 and the top plate component 3.

[0054] In this embodiment, a connecting block 18 is connected to the second limiting strip 16. The connecting block 18 is connected to the end of the second limiting strip 16 and the top plate 3. The second limiting strip 16 is located at the end near the tail plate 9. The second limiting strip 16 is suspended by the connecting block 18. The connecting block 18 is located at the tail end, which makes it convenient to directly install and remove the dustproof part 5 when the front front baffle 11 is opened.

[0055] To facilitate the fixing of the lead wire connected to the terminal 6 and prevent the lead wire from coming loose due to pulling, a wire clamping device 19 is provided on the base plate 1. The wire clamping device 19 is located on the side of the terminal 6 away from the installation space.

[0056] Specifically, the wire clamping device 19 includes a base 20 and a pressure strip 22.

[0057] The base 20 has several first grooves 21 that correspond one-to-one with the terminals 6. The pressure strip 22 has second grooves 23 that correspond to the first grooves 21. The first grooves 21 and the second grooves 23 are arc-shaped grooves used to fit the surface of the wire. The fastening bolts 24 are set at both ends of the pressure strip 22 to fasten the pressure strip 22 to the base 20. After the wires on the terminals 6 are all connected and fastened, the wires are pressed and fixed again by tightening the fastening bolts 24 to prevent them from loosening.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
