A snap-fit ​​modular metallized film capacitor

Abstract

This application relates to the technical field of capacitors, and in particular to a snap-fit ​​modular metallized film capacitor, which includes a capacitor body with slot blocks fixedly connected to both sides of the capacitor body. This invention allows for assembly by pressing the actuating block and utilizing the elastic force of the compression spring to insert the plug block into the corresponding slot block. This transforms multiple capacitor bodies from individual capacitors facing external factors into a relatively unified whole structure. When the equipment is subjected to vibration, bumps, or other external forces, they can share the force. Compared to individual capacitors bearing their own forces when installed independently, this unified structure better resists external forces, reducing the possibility of individual capacitors loosening, shifting, or even falling off. This ensures the connection stability of the capacitors in the circuit and improves the reliability of the entire circuit system.

Description

Technical Field

[0001] This application relates to the technical field of capacitors, and in particular to a snap-fit ​​modular metallized film capacitor. Background Technology

[0002] Metallized film capacitors are typically made by depositing metal onto a plastic film (such as polyester film, polypropylene film, and other common organic film materials) to form a very thin metal layer that acts as an electrode, while the film itself acts as a dielectric. Through processes such as winding, multiple layers of films with metallized electrodes are wound together and equipped with corresponding lead terminals and other structures, and finally packaged to form a capacitor.

[0003] After daily use, the capacitors are installed on the corresponding circuit boards. When multiple capacitors need to be installed, they are installed separately for use. However, when multiple metallized film capacitors are installed, they will bear the force independently when facing external impacts. They do not form an integral structure to jointly resist external forces, so they are more prone to displacement, falling off, etc., resulting in weak stability and anti-interference ability. Utility Model Content

[0004] To address the problems mentioned in the background section, this application provides a snap-fit ​​modular metallized film capacitor.

[0005] This application provides a snap-fit ​​modular metallized film capacitor, which adopts the following technical solution: it includes a capacitor body, and two slot blocks are fixedly connected to both sides of the capacitor body. A sliding opening is provided on the upper side of one of the two slot blocks. A toggle block is slidably fitted on the inner wall of the sliding opening. A plug-in block is fixedly connected to the lower side of the toggle block and slidably fitted with the slot block. The plug-in block is plugged into the other of the two slot blocks.

[0006] A reinforcing opening is provided on the upper side of the other side of the two empty slot blocks, a locking groove is provided on the upper side of the plug-in block, a locking mechanism that cooperates with the locking groove is provided on the upper side of the other side of the two empty slot blocks, a limiting mechanism that cooperates with the toggle block is provided on the upper side of one of the two empty slot blocks, and a compression spring is fixedly connected between the plug-in block and the empty slot block.

[0007] Optionally, the locking mechanism includes a U-shaped frame fixedly connected to the upper side of the empty slot block, a spring piece disposed on the upper side of the inner wall of the U-shaped frame, and a locking tongue disposed at the lower end of the spring piece and slidably engaged inside the locking groove, wherein the locking tongue is inserted into the reinforcing port.

[0008] Optionally, the limiting mechanism includes a movable groove formed on one of the two empty slot blocks, a movable block that slides into the inner wall of the movable groove, and a limiting plate fixedly connected to the upper side of the movable block, wherein the limiting plate cooperates with the actuating block.

[0009] Optionally, a buffer pad is fixedly connected to one side of the toggle block, and multiple anti-slip grooves are provided on one side of the buffer pad.

[0010] Optionally, force plates are fixedly connected to both sides of the latch, and the force plates and the latch are integrally cast.

[0011] Optionally, a compression pad is fixedly connected to one side of the limiting plate, and the compression pad and the actuating block abut against each other.

[0012] Optionally, one side of the plug-in block is set in an arc shape, and the inner wall of the other of the two empty slot blocks is set in an inclined shape.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This invention, by incorporating components such as a capacitor body, a toggle block, a compression spring, and a plug-in block, allows for easy assembly by pressing the toggle block and utilizing the spring force to insert the plug-in block into the corresponding slot. No complex tools or specialized skills are required; ordinary operators can easily perform the task, significantly improving installation efficiency. Furthermore, it enables the assembly of multiple capacitor bodies, transforming them from individual capacitors facing external forces into a unified structure. When the equipment is subjected to vibration, bumps, or other external forces, they can collectively share the load. Compared to individual capacitors bearing their own forces, this integrated structure better resists external influences, reducing the likelihood of loosening, displacement, or even detachment of individual capacitors. This ensures the stability of the capacitor connection in the circuit, guaranteeing its stability and anti-interference capabilities.

[0015] This utility model, by setting a locking mechanism and a limiting mechanism, enables secondary locking after the plug-in block is inserted. First, the spring on the U-shaped frame in the locking mechanism pushes the locking tongue into the locking groove and the reinforcing port. Then, the limiting plate of the limiting mechanism limits the moving block with the help of the compression pad, so that the compression spring no longer exerts force. The multiple locking and limiting mechanisms work together to make the connection between capacitors stable, effectively solving the problem of easy loosening in traditional independent installation. When facing external impacts, the overall impact resistance is significantly improved, ensuring the stable working state of the capacitor in the circuit. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a snap-fit ​​modular metallized film capacitor. For example... Figure 1-5 As shown, the capacitor body 1 is included. Two slot blocks 2 are fixedly connected to both sides of the capacitor body 1. A sliding opening 3 is provided on the upper side of one of the slot blocks 2. A toggle block 4 is slidably fitted on the inner wall of the sliding opening 3. A buffer pad 11 is fixedly connected to one side of the toggle block 4. Multiple anti-slip grooves 12 are provided on one side of the buffer pad 11. The buffer pad 11 fixed on one side of the toggle block 4 can play a buffering role when it is pressed. The multiple anti-slip grooves 12 on one side of the buffer pad 11 increase the friction of the contact surface, making it easier to press the toggle block 4 more stably.

[0024] Please see Figure 3 The lower side of the actuating block 4 is fixedly connected to a plug-in block 5 that slides with the empty slot block 2. One side of the plug-in block 5 is set in an arc shape, and the inner wall of the other empty slot block 2 is set in an inclined shape. When the plug-in operation is performed, the arc-shaped plug-in block 5 can better fit and guide the inclined inner wall of the empty slot block 2, making it easier for the plug-in block 5 to be smoothly inserted into the empty slot block 2, making the splicing operation smoother and more convenient, improving the installation efficiency, and at the same time reducing the damage to the components that may be caused by poor docking to a certain extent. The plug-in block 5 is plugged into the other empty slot block 2.

[0025] Please see Figure 3 A reinforcing opening 6 is provided on the upper side of the other side of the two empty slot blocks 2, a locking groove 7 is provided on the upper side of the plug-in block 5, a locking mechanism 8 that cooperates with the locking groove 7 is provided on the upper side of the other side of the two empty slot blocks 2, a limiting mechanism 9 that cooperates with the toggle block 4 is provided on the upper side of one of the two empty slot blocks 2, and a compression spring 10 is fixedly connected between the plug-in block 5 and the empty slot block 2.

[0026] Please see Figure 4 and Figure 5 The locking mechanism 8 includes a U-shaped frame 801 fixedly connected to the upper side of the empty slot block 2, a spring piece 802 disposed on the upper side of the inner wall of the U-shaped frame 801, and a locking tongue 803 disposed at the lower end of the spring piece 802 and slidably engaged inside the locking groove 7. The locking tongue 803 is inserted into the reinforcing opening 6. Relying on the U-shaped frame 801 fixed to the upper side of the empty slot block 2, the spring piece 802 disposed on the upper side of its inner wall pushes the lower end of the locking tongue 803, causing the locking tongue 803 to slide into the locking groove 7 and engage with the locking mechanism 803. The six-phase reinforcing port is plugged in to lock the relevant components. Both sides of the locking tongue 803 are fixedly connected to the force plate 13. The force plate 13 and the locking tongue 803 are integrally cast. Since the locking tongue 803 is fixedly connected to the two sides of the locking tongue 803 and integrally cast with it, when it is necessary to unlock, external force can be applied to the force plate 13. With the help of its integral structure with the locking tongue 803, the locking tongue 803 can be moved more conveniently and effortlessly, thereby realizing the unlocking operation.

[0027] Please see Figure 5 The limiting mechanism 9 includes a movable groove 901 opened on one of the two empty slot blocks 2, a movable block 902 slidably fitted on the inner wall of the movable groove 901, and a limiting plate 903 fixedly connected to the upper side of the movable block 902. The limiting plate 903 cooperates with the actuating block 4. By pushing the movable block 902 to move inside the movable groove 901, the limiting plate 903 can restrict one side of the actuating block 4. A pressing pad 14 is fixedly connected to one side of the limiting plate 903. The pressing pad 14 and the actuating block 4 abut against each other. When the pressing pad 14 abuts against the actuating block 4, it will produce a certain damping effect on the actuating block 4, making it difficult to move, and can limit the actuating block 4.

[0028] The implementation principle of a snap-fit ​​modular metallized film capacitor in this application embodiment is as follows: When multiple capacitor bodies 1 need to be installed, the two sides of the capacitor body 1 are respectively used as "female end" and "female end". One side of the empty slot block 2 has a sliding plug block 5 built in, and the other side of the empty slot block 2 has a reserved plug channel. When multiple capacitor bodies 1 are installed, after installation, the corresponding plug block 5 will be inserted into the empty slot block 2 of the corresponding capacitor body 1 under the compression of the compression spring 10, so that two adjacent capacitor bodies 1 can be spliced. After splicing, the overall impact resistance is significantly improved, effectively solving the problem of easy loosening in traditional independent installation.

[0029] When the plug block 5 is inserted into the empty slot block 2, the spring piece 802 on the upper side of the inner wall of its U-shaped frame 801 will press the locking tongue 803. After the locking tongue 803 is inserted into the locking groove 7 on the upper side of the plug block 5, the plug block 5 is locked a second time, which can further improve the locking and improve the stability.

[0030] Once the actuating block 4 is fixed, the movable block 902 can slide inside the movable groove 901, causing the limiting plate 903 to press against one side of the actuating block 4, thereby limiting the actuating block 4 and preventing the compression spring 10 from exerting force, thus ensuring its stability during use.

[0031] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
