Description

Technical Field

[0001] This utility model relates to an assembly structure, and more particularly to a high-power power supply assembly structure, belonging to the field of power supply equipment technology. Background Technology

[0002] Existing high-power power supply designs generally suffer from the following problems in heat dissipation:

[0003] 1. Low heat dissipation efficiency: In traditional solutions, heat-generating components such as MOSFETs and diodes are indirectly in contact with the casing through thermal pads, resulting in a long heat transfer path and poor heat dissipation.

[0004] 2. Insufficient waterproof performance: To fix the circuit board or heat dissipation components, holes are usually made on the side of the aluminum shell to lock screws, which leads to a decrease in sealing and makes it easy for water to seep through the screw holes.

[0005] 3. Complex and unattractive structure: Exposed screw holes affect the product's appearance and require additional components such as sealing rings, increasing assembly costs and complexity.

[0006] In view of this, a novel high-power power supply assembly structure is proposed to solve the above-mentioned technical problems. Utility Model Content

[0007] To address the shortcomings of the aforementioned technologies, this utility model provides a high-power power supply assembly structure, specifically a high-power power supply assembly structure based on a metal casing, which is particularly suitable for outdoor power supply equipment requiring high heat dissipation and waterproof performance, aiming to solve the heat dissipation, waterproof, and structural defects in the prior art.

[0008] To solve the above technical problems, the technical solution adopted by this utility model is: a high-power power supply assembly structure, including a housing, a circuit board installed inside the housing, a heating element installed on the circuit board, and the heating element contacting the inner wall of the housing through an elastic clip;

[0009] The inner wall of the housing has symmetrical slots along its length. One end of the elastic clip is inserted into the slot, and the other end extends to the top of the circuit board to clamp and connect with the heating element. The elastic clip makes the heating element fit tightly against the inner wall of the housing.

[0010] Preferably, the elastic clip includes an arc-shaped clamping plate and an insertion plate connected to the clamping plate. A connecting plate is provided between the insertion plate and the clamping plate, and the connecting plate is connected to the clamping plate through an extension plate.

[0012] Preferably, the housing includes a bottom shell and a top cover that engages with the bottom shell, with plugs installed at both ends of the bottom shell and a matching cap placed on top of the plugs.

[0013] Preferably, the plug includes an input plug and an output plug, and screw slots are formed on both sides of the bottom shell. The input plug and the output plug are fastened to the bottom shell by screws.

[0014] Preferably, the input end plug has a single locking hole, in which an input wire with a tail clip is locked; the output end plug has two locking holes, in which an output wire with a tail clip is locked.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 , Figure 2The high-power power supply assembly structure shown includes a housing 100. Preferably, the housing is made of aluminum. A circuit board 7 is installed inside the housing 100. A heating element 3 is installed on the circuit board 7. The heating element 3 is in contact with the inner wall of the housing through an elastic clip 2.

[0026] The inner wall of the housing 100 is symmetrically formed with slots 10 along the length direction. One end of the elastic clip 2 is inserted into the slot, and the other end extends to the top of the circuit board and is clamped to the heating element. The elastic clip makes the heating element fit tightly against the inner wall of the housing.

[0027] A slot is made on the bottom shell, through which the heat-generating components (MOSFETs, diodes) are directly attached to the inner wall of the aluminum shell, improving heat dissipation efficiency; it replaces the traditional side screw design, enhances waterproof performance, simplifies the assembly process, reduces production costs, and improves the appearance.

[0028] By using a slot and an elastic clip, one end of the elastic clip is inserted into the slot of the aluminum shell, and the slot is used to fix the elastic clip in place. The other end of the elastic clip is placed over the heating element on the circuit board by the elastic clamping action of the clip. The continuous pressure generated by its own elastic deformation makes the heating element fit tightly against the inner wall of the aluminum shell. No holes are needed on the side of the aluminum shell to lock screws, achieving screwless sealing. At the same time, combined with the overall sealing process of the shell (potting process), an IP67 or higher waterproof rating is achieved.

[0029] like Figure 3 As shown, the elastic clip 2 includes an arc-shaped clamping plate 22 and an insertion plate 21 connected to the clamping plate. A connecting plate 23 is provided between the insertion plate 21 and the clamping plate 22, and the connecting plate 23 is connected to the clamping plate 22 through an extension plate 24. The clamping plate 22 presses against the surface of the heating element, and the insertion plate 21 is fitted into the slot. The insertion plate 21 and the extension plate 24 are parallel to each other.

[0030] Preferably, the elastic clip 2 is a manganese steel clip, which is made of elastic metal. One end of the elastic clip is embedded in the slot for fixation, and the other end extends to the circuit board area to form an elastic clamping force on the MOSFET and diode, pressing them tightly against the inner wall of the housing (aluminum housing). The elastic clip forms an elastic clamping force on the heating element, making the heating element fit tightly against the inner wall of the housing.

[0031] The housing 100 includes a bottom shell 6 and an upper cover 1 that engages with the bottom shell. Plugs are installed at both ends of the bottom shell 6, and the upper cover 1 is fitted with a cap at the top of the plug.

[0032] The inner sidewall of the casing features two slots, the depth and width of which are adapted to the installation requirements of the elastic clips. The top cover and the bottom casing of the power supply are installed together to form the basic structure of the power supply. The top cover also secures the cable by pressing down on the tail clip. The bottom casing has four screw slots for securing two plugs with eight self-tapping screws. Figure 4 As shown, the elastic clip uses a slot to attach the heating element to the inner wall, while simultaneously performing basic assembly with the top cover.

[0033] Preferably, the plug includes an input plug 5 and an output plug 8. Screw slots are formed on both sides of the bottom shell 6. The input plug 5 and the output plug 8 are fastened to the bottom shell 6 by screws.

[0034] The input plug (single-hole input plug) has one locking hole to ensure a tight fit between the input wire and the output plug (double-hole output plug) has two locking holes to ensure a tight fit between the output wire and the output wire. Both are important components for waterproofing.

[0035] The input end plug 5 has a single locking hole, in which an input wire 4 with a tail clip is locked. The output end plug 8 has two locking holes, in which an output wire 9 with a tail clip is locked.

[0036] There is one input cable with a tail card, which enables AC input and output; there are two output cables with tail cards, which enable DC output. Both are standard cables.

[0037] Circuit board 7 is installed inside the bottom shell 6, and is soldered to the input line 4 with tail card and the output line 9 with tail card respectively. The circuit board carries the entire circuit structure of the power supply.

[0038] Preferably, the heating element 3 is a MOSFET or a diode. The heating element (MOSFET or diode) is positioned on the side close to the inner wall of the aluminum shell. During installation, the pressure of the elastic clips makes it directly contact the inner wall of the shell, forming an efficient heat conduction path.

[0039] The installation process of this utility model is as follows: First, screw the input end plug 5 and the output end plug 8 to both ends of the bottom shell 6. Then, place the circuit board 7, which has been soldered with the input line 4 with the tail card and the output line 9 with the tail card, into the aluminum bottom shell. Insert the input line 4 with the tail card and the output line 9 with the tail card into the input end plug 5 and the output end plug 8 respectively. Then, use the elastic clip 2 to clamp the heating element (MOS tube or diode) through the slot 10 in the bottom shell 6 and stick it to the inner wall of the bottom shell 6. Finally, assemble the top cover 1 on the bottom shell 6 to complete the assembly of the entire product.

[0040] The purpose of this utility model is to provide a high-power power supply assembly structure. Through the structural innovation of the slot and elastic clip, the heat dissipation channel and mechanical fixing function are integrated, replacing the traditional separate design of screw + thermal pad, realizing integrated heat dissipation and fixing; eliminating the perforation on the side of the shell, fundamentally eliminating the water seepage path, and optimizing the waterproof performance; the plug-in design of the elastic clip and slot supports quick installation, realizes modular assembly, and reduces labor costs.

[0041] Compared with the prior art, the present invention has the following advantages:

[0042] 1. Improved heat dissipation: The heat-generating element is in direct contact with the aluminum shell, reducing thermal resistance by more than 50%, and the measured temperature drop of the MOSFET can reach 15-25℃;

[0043] 2. Enhanced waterproof reliability: With no side perforations and an overall sealing process, it can pass the immersion test (1 meter water depth / 30 minutes);

[0044] 3. Reduced production costs: Fewer screws, sealing rings, and other parts are used, assembly steps are simplified, and labor time is reduced by 30%;

[0045] 4. Appearance optimization: There are no exposed screws on the side of the housing, and the surface is flat and beautiful, making it suitable for high-end outdoor equipment;

[0046] 5. Ease of maintenance: The removable elastic clips facilitate the replacement of heating elements later without damaging the housing structure.

[0047] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
