Abstract

This utility model relates to the field of combined capacitor technology, specifically to a modular combined capacitor, including a circuit board and individual capacitors. The individual capacitors are disposed on the top of the circuit board, and a series mechanism is provided on the outside of the individual capacitors. This utility model places multiple individual capacitors in a collar, and then inserts the multiple individual capacitors into the circuit board and fixes them with solder. By simultaneously inserting multiple individual capacitors, the installation efficiency of the individual capacitors is improved. After multiple sets of individual capacitors are fixed, the pin of the first positioning frame is inserted through multiple end blocks to position the collar. The individual capacitors are limited by the convex plates. At this time, the first positioning frame and the second positioning frame insert the individual capacitors on both sides, and cooperate with the two adjacent convex blocks to synchronously limit the multiple sets of individual capacitors, ensuring the installation stability of multiple sets of individual capacitors and preventing the individual capacitors from bending after installation.

Description

Technical Field

[0001] This utility model relates to the field of combined capacitor technology, specifically a modular combined capacitor. Background Technology

[0002] A combined capacitor is a device composed of multiple capacitors connected in a specific way. It is mainly used for reactive power compensation and harmonic control. It is usually composed of core components such as intelligent measurement and control unit, zero-crossing switching relay, and power capacitor. It can be used independently or networked to form a compensation system, supporting three-phase or phase-by-phase compensation.

[0003] Currently, when assembling a modular capacitor, multiple capacitors are usually installed and positioned one by one. However, modular capacitors are usually assembled from a large number of capacitors. Each capacitor is plugged into a circuit board, and holes need to be aligned and then soldered, which makes the assembly process relatively slow.

[0004] Therefore, a modular combined capacitor is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a modular combined capacitor, which solves the problem that current combined capacitors are usually assembled by installing and positioning multiple capacitors one by one. However, combined capacitors are usually assembled from a large number of capacitors, and each capacitor needs to be plugged into a circuit board and then soldered, which results in slow assembly efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a circuit board and a single capacitor. The single capacitor is disposed on the top of the circuit board. A series mechanism is provided on the outside of the single capacitor. The series mechanism includes a collar, a through slot, a side plate, a convex plate, a protrusion, and a connecting block. The collar is sleeved on the outside of the single capacitor. The through slot is formed on the outside of the collar. The side plate is integrally formed at the port of the collar. The convex plate is integrally formed on the outside of one end of the side plate. The protrusion is integrally formed on the outside of the side plate. The connecting block is disposed between two adjacent collars.

[0007] Preferably, the connecting block is integrally formed on the outside of the collar, and the two collars are integrally formed on the outside of the connecting block.

[0008] Preferably, the convex plate abuts against one end of the single capacitor, and the side plate is attached to the outside of the single capacitor.

[0009] Preferably, one end of the end collar is integrally formed with an end block, a through hole is provided on the outer side of the end block, and a positioning mechanism is provided on the outer side of the end block.

[0010] Preferably, the positioning mechanism includes a first positioning frame, a second positioning frame, a groove, a pin, a sleeve, a nut, and a bracket. The first positioning frame and the second positioning frame are respectively disposed at both ends of the circuit board. The groove is formed on the outer side of the first positioning frame and the second positioning frame. The pin is fixedly connected to both ends of the first positioning frame. The sleeve is fixedly connected to the end of the second positioning frame. The nut is threadedly connected to one end of the pin. The bracket is fixedly connected to the bottom of the first positioning frame and the second positioning frame.

[0011] Preferably, the bracket has an L-shaped structure, and a groove is provided at the connection between the bracket and the first positioning frame, with the inner wall of the groove fitting against the outer wall of the circuit board.

[0012] Preferably, the first positioning frame and the second positioning frame are connected to the single capacitor through a groove, the pin slides through the through hole, the inner wall of the through hole fits with the outer wall of the pin, and the pin slides through the sleeve.

[0013] Compared with the prior art, this utility model provides a modular combined capacitor with the following features:

[0014] Beneficial effects:

[0015] 1. Multiple individual capacitors are placed inside the collar, and then the multiple individual capacitors are plugged into the circuit board and soldered to fix them. By setting up multiple individual capacitors to be plugged in simultaneously, the installation efficiency of individual capacitors is improved.

[0016] 2. After the multiple sets of individual capacitors are fixed, the pin of the first positioning frame is inserted through multiple end blocks to position the collar. The individual capacitors are limited by the convex plate. At this time, the individual capacitors on both sides of the first and second positioning frames are inserted and the two adjacent convex blocks are fitted together to synchronously limit the multiple sets of individual capacitors, ensuring the stable installation of the multiple sets of individual capacitors and preventing the individual capacitors from bending after installation.

[0022] 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.

[0023] Example:

[0024] Please see Figures 1-4 This embodiment of a modular combined capacitor includes a circuit board 1 and a single capacitor 2. The single capacitor 2 is disposed on the top of the circuit board 1. A series mechanism is disposed on the outside of the single capacitor 2. The series mechanism includes a collar 3, a through groove 4, a side plate 5, a protruding plate 6, a protrusion 7, and a connecting block 8. The collar 3 is sleeved on the outside of the single capacitor 2. The through groove 4 is opened on the outside of the collar 3. The side plate 5 is integrally formed at the port of the collar 3. The protruding plate 6 is integrally formed on the outside of one end of the side plate 5. The protrusion 7 is integrally formed on the outside of the side plate 5. The connecting block 8 is disposed between two adjacent collars 3.

[0025] Multiple individual capacitors 2 are placed inside the collar 3, and then the multiple individual capacitors 2 are plugged into the circuit board 1 and soldered to fix them. By setting up the simultaneous plugging of multiple individual capacitors 2, the installation efficiency of individual capacitors 2 is improved.

[0026] Furthermore, the connecting block 8 is integrally formed on the outside of the collar 3, and the two collars 3 are integrally formed on the outside of the connecting block 8.

[0027] Furthermore, the protruding plate 6 abuts against one end of the single-cell capacitor 2, and the side plate 5 is attached to the outside of the single-cell capacitor 2.

[0028] Furthermore, one end of the end collar 3 is integrally formed with an end block 9, and a through hole 10 is provided on the outer side of the end block 9. A positioning mechanism is provided on the outer side of the end block 9.

[0029] Furthermore, the positioning mechanism includes a first positioning frame 11, a second positioning frame 12, a groove 13, a pin 14, a sleeve 15, a nut 16, and a bracket 17. The first positioning frame 11 and the second positioning frame 12 are respectively disposed at both ends of the circuit board 1. The groove 13 is formed on the outer side of the first positioning frame 11 and the second positioning frame 12. The pin 14 is fixedly connected to both ends of the first positioning frame 11. The sleeve 15 is fixedly connected to the end of the second positioning frame 12. The nut 16 is threadedly connected to one end of the pin 14. The bracket 17 is fixedly connected to the bottom of the first positioning frame 11 and the second positioning frame 12.

[0030] After the multiple sets of individual capacitors 2 are fixed, the first positioning frame 11 and the second positioning frame 12 are connected to the circuit board 1 through the bracket 17, so that the pin 14 of the first positioning frame 11 passes through and inserts multiple end blocks 9, and the sleeve 15 of the second positioning frame 12 is inserted and fixed with the nut 16, thereby positioning the collar 3. The individual capacitors 2 are limited by the protrusion 6. At this time, the first positioning frame 11 and the second positioning frame 12 are inserted into the individual capacitors 2 on both sides, and the two adjacent protrusions 7 are in contact, thereby synchronously limiting the multiple sets of individual capacitors 2, ensuring the stable installation of the multiple sets of individual capacitors 2, and preventing the individual capacitors 2 from bending after installation.

[0031] Furthermore, the bracket 17 has an L-shaped structure, and a groove is provided at the connection between the bracket 17 and the first positioning frame 11. The inner wall of the groove is in contact with the outer wall of the circuit board 1.

[0032] Furthermore, the first positioning frame 11 and the second positioning frame 12 are inserted into the single capacitor 2 through the groove 13, and the pin 14 slides through and inserts into the through hole 10. The inner wall of the through hole 10 fits against the outer wall of the pin 14, and the pin 14 slides through and inserts into the sleeve 15.

[0033] The working principle of the above embodiment is as follows: multiple individual capacitors 2 are placed inside the collar 3, and then the multiple individual capacitors 2 are inserted into the circuit board 1 and soldered to fix them. By setting the multiple individual capacitors 2 to be inserted synchronously, the installation efficiency of the individual capacitors 2 is improved. After the multiple sets of individual capacitors 2 are fixed, the first positioning frame 11 and the second positioning frame 12 are inserted into the circuit board 1 through the bracket 17, so that the pin 14 of the first positioning frame 11 passes through and inserts multiple end blocks 9, and inserts the sleeve 15 of the second positioning frame 12 and fixes it with the nut 16, thereby positioning the collar 3. The individual capacitors 2 are limited by the protrusion 6. At this time, the first positioning frame 11 and the second positioning frame 12 insert the individual capacitors 2 on both sides, and cooperate with the two adjacent protrusions 7 to fit together, thereby synchronously limiting the multiple sets of individual capacitors 2, ensuring the stable installation of the multiple sets of individual capacitors 2, and preventing the individual capacitors 2 from bending after installation.
