Description

Technical Field

[0001] This application relates to the field of electronic experimental device technology, specifically to a high-power filter circuit mounting platform. Background Technology

[0002] With the development of artificial intelligence, applications such as smart factories involve numerous high-power electrical systems and complex electronic systems, making the electromagnetic environment more complex and posing greater challenges to electromagnetic compatibility (EMC) technology. Meanwhile, domestic EMC standards and regulations are becoming increasingly stringent, and companies often lack awareness of EMC design when developing new products, leading to frequent EMC remediation during EMC testing. The primary measure in EMC remediation is adding filters, and the parameters of the filter circuit require multiple tests and verifications to determine the optimal circuit structure and component parameters. This process necessitates frequent component replacements by testing personnel, increasing remediation time and wear and tear on electronic components.

[0003] Although traditional circuit boards (plug-in boards, universal boards, breadboards) allow the pins of electronic components (such as inductors and capacitors) to be inserted and connected by thin wires to form the desired circuit, their design has the following problems that lead to the above situation:

[0004] 1. The bottom of the metal spring is sealed, and leaded devices need to have their leads trimmed for safe use, resulting in a high device scrap rate;

[0005] 2. The contact area between the metal spring and the metal pin is small, making it unsuitable for high-power circuits, such as 100Vdc / 5A and above.

[0006] 3. When expanding the platform, electrical connections are established using thin wires such as DuPont wires, resulting in low current carrying capacity, reliability, and safety. Utility Model Content

[0007] To address these issues, this application provides a high-power filter circuit mounting platform to solve the problems of high device scrap rate, low current carrying capacity between metal springs and metal pins, and low current carrying capacity, reliability, and safety after electrical connection in the prior art.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] A high-power filter circuit mounting platform includes a cover plate, a base, and a fixing seat. The cover plate and the base are both made of insulating material, and a plurality of metal springs are fixed on the fixing seat.

[0010] The upper surface of the base is provided with a horizontal slot for inserting a fixing seat. The bottom wall of the horizontal slot has a first pin hole extending downwards. The cover plate has multiple insertion holes for inserting metal springs, and the positions of the insertion holes correspond to the horizontal slot. The fixing seat and the metal spring are respectively provided with connected second pin holes. When the fixing seat is inserted into the horizontal slot, the second pin holes correspond one-to-one with the first pin holes.

[0011] A connecting post is fixed at each end of the fixing base. Circular holes for the connecting posts to pass through are opened on both sides of the cover plate. Bolts and conductive copper wires are fitted to the top of the connecting posts, and the bolts are higher than the cover plate.

[0012] Optionally, the metal spring includes two clips, with an arc-shaped notch between the two clips for inserting a pin.

[0013] Optionally, a boss is fixed on the upper surface of the cover plate, and the boss is used to place a common mode inductor.

[0014] Optionally, the boss extends downward and protrudes from the bottom surface of the cover plate; the upper surface of the base is provided with a positioning groove that matches the boss, and the positioning groove corresponds to the position of the boss.

[0015] Optionally, the base and the cover plate are fixed together by a latch, and both the base and the cover plate have a horizontally extending locking groove on their sides, which is engaged with the latch.

[0016] Optionally, an insulating wall is installed at the bottom of the base.

[0017] Optionally, the latch is made of stainless steel and the surface of the latch is covered with an epoxy resin insulating layer.

[0018] Optionally, both the base and the cover plate are injection molded.

[0019] Compared with the prior art, this application has at least the following beneficial effects:

[0020] 1. By using the sockets on the cover plate, the first pin hole and the second pin hole at the base and the metal spring, the pin space is increased, avoiding damage to the shape of the leaded device, improving the utilization rate of the leaded device, and reducing testing costs. Furthermore, the connecting posts of the metal spring, bolts, and conductive copper wires allow for the expansion of the platform for high-power circuits. The bolts also enable electrical connections between the input / output lines and the filter circuit, significantly improving safety and reliability.

[0021] 2. By adding an arc-shaped notch to the parallel surface between the two clips of the metal spring, the contact area between the metal pin and the metal spring can be increased, thereby increasing the rated power of the mounted circuit and improving the applicability of high-power circuits.

[0022] 3. The boss and the positioning groove work together to position the relative positions of the base and the cover plate, so as to avoid misalignment during installation. Attached Figure Description

[0032] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," "third," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0034] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to indicate the general relative positional relationship for the purpose of intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationship in the actual product.

[0035] A high-power filter circuit mounting platform, referring to Figures 1-6 It includes a cover plate 1, a base 2, and multiple fixing seats 3. The cover plate 1 and the base 2 are both made of insulating material and are injection molded in one piece. The fixing seat 3 is elongated and has multiple metal springs 4 fixed side by side on it. Each metal spring 4 consists of two clips.

[0036] The upper surface of the base 2 has multiple horizontal slots 5 for inserting the fixing seats 3. The bottom wall of the horizontal slots 5 has a circular first pin hole 17 extending downwards. The fixing seats 3 are inserted into the horizontal slots 5 one by one, with the metal springs 4 standing upright facing upwards.

[0037] Correspondingly, the cover plate 1 has multiple spaced square sockets 6, each socket 6 for inserting a metal spring 4. The positions of the sockets 6 correspond to the horizontal slots 5, so that after the cover plate 1 is placed on the base 2, each metal spring 4 can be inserted into the corresponding square socket 6, and the top of the metal spring 4 contacts the top surface of the cover plate 1, realizing the electrical connection between different sockets 6.

[0038] The mounting base 3 and the metal spring 4 are respectively provided with corresponding and interconnected second pin holes 7, so that when the mounting base 3 is inserted into the horizontal slot 5, the second pin holes 7 correspond one-to-one with the first pin holes 17. In this way, after the metal pins are inserted into the metal spring 4, they can pass through the first pin holes 17 and the second pin holes 7 and extend to the bottom of the base 2, without having to cut the metal pins of the device during the experiment, thus reducing the scrap rate.

[0039] The bottom of the base 2 is also provided with several insulating walls 8 to prevent electrical short circuits from occurring during testing at higher operating voltages. The metal leads pass through the first pin hole 17 and the second pin hole 7 and are positioned at the insulating walls 8.

[0040] Each metal spring 4 has an arc-shaped notch 9 between its two clips for inserting pins, thereby increasing the contact area between the pins and the metal spring 4 and fixing the pins in place.

[0041] A connecting post 10 is fixed at each end of the fixed base 3, so that the metal spring 4 is positioned between the two connecting posts 10. Circular holes 11 are opened on both sides of the cover plate 1 for the connecting posts 10 to pass through. After the cover plate 1 is connected to the base 2, the top of the connecting post 10 contacts the top of the cover plate 1.

[0042] The top of the connecting post 10 is fitted with a bolt 12 and a conductive copper wire, which can expand the filter circuit, and the bolt 12 is higher than the cover plate 1.

[0043] Furthermore, a circular boss 13 is fixed at the center of the upper surface of the cover plate 1. The boss 13 is used to place the common mode inductor. Placing the common mode inductor on the boss 13 increases the electrical clearance between the common mode inductor and the metal spring 4, thereby increasing safety during the testing process.

[0044] Furthermore, the boss 13 extends downwards and protrudes from the bottom surface of the cover plate 1. Correspondingly, the upper surface of the base 2 is provided with a positioning groove 14 that matches the boss 13, and the positioning groove 14 is positioned opposite to the boss 13. The two work together to limit the movement and prevent misalignment between the base 2 and the cover plate 1 due to operational errors during installation.

[0045] To ensure a stable connection between the base 2 and the cover plate 1, a latch 15 is used to secure them together. Correspondingly, both the base 2 and the cover plate 1 have laterally extending locking grooves 16 on their sides, with both ends of the locking grooves 16 penetrating both sides of the base 2 and the cover plate 1. The locking grooves 16 and the latches 15 engage in a plug-in fit. To secure the base 2 and cover plate 1, slide the latch 15 into one end of the locking groove 16. To remove the cover plate 1, simply move the latch 15 towards one end of the locking groove 16 until it slides out of the locking groove 16 to release the connection between the base 2 and the cover plate 1.

[0046] In this embodiment, the latch 15 is made of stainless steel and the surface of the latch 15 is covered with an epoxy resin insulating layer.

[0047] The square socket 6 has a side length of 5mm and a height that is the same as the thickness of the cover plate 1, both being 10mm.

[0048] The metal spring 4 has a height of not less than 15mm, a thickness of 1mm, a radius of 0.2mm for the arc-shaped notch 9, and a current carrying capacity of up to 50A.

[0049] The insulating wall 8 is 25mm high and 3mm thick, and can withstand a 4kVDC voltage surge.

[0050] The implementation principle of this application embodiment is as follows: When the high-power filter circuit mounting platform is in use, electronic components are inserted into the square sockets 6 at the corresponding positions according to the filter circuit topology diagram, and the metal pins of the components are fixed by the arc-shaped notch 9 of the metal spring 4. The pins of the electronic components pass through the first pin hole 17 and the second pin hole to reach the area of ​​the insulating wall 8, and an electrical connection is established between the pins of the components in the transverse groove. By using conductive copper wire to wrap and fix the bolts 12 at different positions, the number of sockets 6 for establishing electrical connections can be expanded, and more electronic component pins can be electrically connected. This avoids the phenomenon of long wires, messy circuits, and complex electromagnetic environment caused by surface flying wires. Moreover, this method allows for intuitive observation of the connection relationship of the wires.

[0051] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
