Description

Technical Field

[0001] This utility model relates to the field of mounting surface-mount capacitors, and more particularly to a parallel structure surface-mount capacitor. Background Technology

[0002] Parallel surface mount capacitors typically refer to multiple surface mount capacitors connected side-by-side in a circuit design, sharing the same voltage to increase the total capacitance.

[0003] A search of Chinese Patent Publication No. CN221596194U reveals a parallel structure surface mount capacitor, relating to the field of surface mount capacitor mounting. This parallel structure surface mount capacitor includes a surface mount capacitor body and a mounting block mounted on the side of the surface mount capacitor body. The outer surface of the mounting block is coated with an epoxy resin to prevent electric shock to the operator during installation and disassembly. A fixing groove is formed on one end surface of the mounting block, and a cavity is formed inside the mounting block. A snap-fit ​​mechanism is located at the bottom of the mounting block for snapping two adjacent surface mount capacitors together. A fixing mechanism is installed inside the cavity to fix the snap-fit ​​mechanism, and a movable mechanism is formed inside the cavity to move the fixing mechanism. The surface mount capacitor body is electrically connected to the snap-fit ​​mechanism.

[0004] To address the time-consuming and labor-intensive problem of installation via welding, the aforementioned patent proposes a method that involves bending the lower locking mechanism outwards and welding it onto the circuit board. Then, the locking mechanism of the next surface-mount capacitor is placed in the fixing slot and pressed down. This causes the locking mechanism to push the fixing mechanism, which in turn stretches the movable mechanism. After pressing, the movable mechanism extends and retracts, and the fixing mechanism secures the locking mechanism, thus fixing the surface-mount capacitor.

[0005] However, in actual use, the fixed spacing design reduces the versatility between the circuit board and the capacitor. When it is necessary to be compatible with various capacitor layouts and specifications, electronic engineers need to design and produce multiple versions of circuit boards to adapt to different application scenarios. This not only increases the cost of development and production, but also increases the time investment.

[0006] Therefore, this utility model provides a parallel structure chip capacitor. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a parallel structure chip capacitor.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a parallel structure chip capacitor, comprising a chip capacitor body and a plug-in copper plate, wherein both sides of the chip capacitor body are fixedly connected to a non-polar fixing component, and a positioning component is fixedly connected inside the non-polar fixing component;

[0009] The infinitely variable fixing assembly includes an epoxy resin coating. One side of the epoxy resin coating is fixedly connected to both sides of the surface mount capacitor body. The internal thread of the epoxy resin coating is connected to a forward bolt. The internal end of the epoxy resin coating away from the forward bolt is threadedly connected to a reverse bolt. The outer thread of the forward bolt is threadedly connected to a forward clamping plate. The outer thread of the reverse bolt is threadedly connected to a reverse clamping plate. A slider is fixedly connected to the top of both the forward and reverse clamping plates. A groove is formed inside the epoxy resin coating.

[0011] The technical advantages of adopting the above-mentioned technical solution are: it enables a fast and simple installation process. Because the non-polarized fixing components on both sides of the surface-mount capacitor body can be flexibly adjusted, the fixing distance between the capacitor and the circuit board is adjustable, thereby improving the versatility of the capacitor and the circuit board.

[0012] In a preferred embodiment, one end of the forward bolt and the reverse bolt are rotatably connected to the epoxy resin coating.

[0013] The technical advantages of adopting the above solution are: it enables a quick and simple installation process. This is because the non-polarized fixing components on both sides of the surface mount capacitor body can be flexibly adjusted.

[0014] In a preferred embodiment, the outer side of the slider is slidably connected to the groove.

[0015] The technical effect of adopting the above technical solution is to ensure that the forward clamp and the reverse clamp remain stable when sliding.

[0016] In a preferred embodiment, the outer side of the positioning threaded post is slidably connected to the forward clamping plate and the reverse clamping plate.

[0018] In a preferred embodiment, the outer side of the positioning threaded post is slidably connected to the insertion copper plate.

[0019] The technical effect of adopting the above technical solution is to improve the positioning accuracy of the surface mount capacitor on the circuit board, thereby ensuring a more stable connection between the capacitor and the circuit board.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] This invention first places the capacitor patch on the circuit board, then adjusts the positioning column to ensure the copper plate is aligned with the circuit board's insertion hole. Once the copper plate is correctly inserted, the positioning threaded column maintains its alignment. The clamping plate spacing is adjusted by rotating the bolts, and the slider design in the groove ensures smooth movement of the clamping plate and avoids jamming. After clamping the copper plate, rotating the positioning column fixes the clamping plate to the copper plate. This design achieves rapid positioning and fixation of the capacitor assembly on the circuit board, while allowing flexible adjustments for different layout requirements. It effectively reduces the need to design and produce multiple versions of circuit boards to adapt to different application scenarios, thereby reducing development and production costs and shortening time investment.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a parallel structure chip capacitor, including a chip capacitor body 1 and a plug-in copper plate 4, with a non-polar fixing component 2 fixedly connected to both sides of the chip capacitor body 1, and a positioning component 3 fixedly connected inside the non-polar fixing component 2.

[0033] The electrodeless fixing assembly 2 includes an epoxy resin coating 21. One side of the epoxy resin coating 21 is fixedly connected to both sides of the surface-mount capacitor body 1. The internal thread of the epoxy resin coating 21 is connected to a forward bolt 22. One end of the forward bolt 22 and the reverse bolt 23 are rotatably connected to the epoxy resin coating 21. The internal end of the epoxy resin coating 21 away from the forward bolt 22 is threadedly connected to the reverse bolt 23. The external thread of the forward bolt 22 is threadedly connected to a forward clamp 24, and the external thread of the reverse bolt 23 is threadedly connected to a reverse clamp 25. Slider 26 is fixedly connected to the top of both the forward clamp 24 and the reverse clamp 25. A groove 27 is formed inside the epoxy resin coating 21, and the external side of the slider 26 is slidably connected to the groove 27. The surface-mount capacitor body 1 is the core of the entire capacitor assembly, responsible for storing and releasing charge. The design of the interlocking copper plate 4 is used to ensure stable interconnection between multiple capacitors. The high overall capacitance of the circuit, along with the epoxy resin coating 21, not only provides electrical isolation protection to prevent accidental electric shock but also enhances the mechanical protection of the capacitor body from the external environment. The forward bolt 22 and reverse bolt 23, connected by threads, provide precise mechanical adjustment, allowing the distance between the two clamps to be adjusted according to actual needs. This design allows for flexible arrangement and fixation of the capacitors on the circuit board to adapt to different layout requirements. The forward clamp 24 and reverse clamp 25 are adjusted by bolts to keep the capacitor stable. The design makes the adjustment process quick and simple, and adjustment and locking can be achieved by rotating the bolts, greatly facilitating installation and subsequent adjustment. The sliding design of the slider 26 in the groove 27 ensures smooth and precise movement of the clamps, effectively avoiding jamming or high resistance. This design improves the convenience of operation while ensuring the stability and parallelism of the clamps during fixation.

[0034] Furthermore, such as Figure 1 , Figure 2 and Figure 4As shown: The positioning component 3 includes a positioning threaded post 31. The outer side of the positioning threaded post 31 is slidably connected to the insertion copper plate 4. The outer side of the positioning threaded post 31 is slidably connected to the forward clamping plate 24 and the reverse clamping plate 25. One end of the positioning threaded post 31 is fixedly connected to the epoxy resin coating 21. The outer side of the positioning threaded post 31 is threadedly connected to a positioning rotating post 32. The end of the positioning rotating post 32 away from the positioning threaded post 31 is fixedly connected to a handle 33. The positioning threaded post 31 plays a key connecting role in the whole structure. By sliding its outer side to the insertion copper plate 4, the forward clamping plate 24 and the reverse clamping plate 25, the alignment between these components is ensured. The fixed connection of one end of the positioning threaded post 31 to the epoxy resin coating 21 provides a stable fixing point, ensuring that the whole component will not be misaligned or loosened due to external forces during operation. The design of the positioning rotating post 32 can fix the insertion copper plate 4 after positioning. The design of the handle 33 allows the user to quickly adjust the positioning rotating post 32.

[0035] Working principle:

[0036] like Figure 1 - Figure 4 As shown:

[0037] In use: First, place the parallel-structure chip capacitor in the predetermined position on the circuit board. Then, by rotating the handle 33 on the forward clamp 24 and the reverse clamp 25, adjust the positioning column 32 to align the insertion copper plate 4 with the corresponding socket on the circuit board. Once the insertion copper plate 4 is correctly inserted into the socket on the circuit board, the positioning threaded column 31 will ensure that the insertion copper plate 4 remains aligned with the forward clamp 24 and the reverse clamp 25. Next, by rotating the forward bolt 22 and the reverse bolt 23, the distance between the forward clamp 24 and the reverse clamp 25 can be precisely adjusted to adapt to different layout requirements on the circuit board. This adjustment allows for flexible arrangement and fixation of the capacitor assembly on the circuit board, thereby optimizing the overall performance of the circuit. During the adjustment process, the sliding design of the slider 26 in the groove 27 ensures smooth and precise movement of the clamps, effectively avoiding jamming or high resistance. After clamping the insertion copper plate 4, rotate the positioning column 32 again to firmly fix the forward clamp 24, the reverse clamp 25 and the insertion copper plate 4 together.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
