Description

Technical Field

[0001] This utility model relates to the field of capacitor manufacturing technology, and in particular to a positioning-free capacitor mounting structure. Background Technology

[0002] When assembling a capacitor assembly, the capacitors need to be filled in advance, and then the filled capacitors are placed into the mounting housing before assembly is completed.

[0003] This assembly method requires two production processes. In addition, since the capacitor has a separate housing, and the housing is then fitted into the mounting housing, the entire capacitor assembly structure is relatively large, requiring a large installation space, which is not conducive to the production needs of modern integrated and miniaturized equipment.

[0004] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a positioning-free capacitor mounting structure, making it more valuable for industrial applications. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a positioning-free capacitor mounting structure.

[0006] This utility model discloses a positioning-free capacitor mounting structure, including a housing with a recessed mounting compartment in the middle. Inside the mounting compartment, an insulating frame, a lower copper busbar, a core, and an upper copper busbar are placed sequentially from bottom to top. The lower copper busbar contacts the lower terminal block, and the upper copper busbar contacts the upper terminal block. The lower and upper terminal blocks are fixed to the two sides of the mounting compartment in the housing by bolts.

[0007] This positioning-free capacitor mounting structure allows the mounting compartment inside the casing to directly mount the lower copper busbar, core, upper copper busbar, lower terminal block, and upper terminal block structure of the capacitor, avoiding secondary operations and effectively reducing the size of the capacitor after installation.

[0008] Furthermore, there is an opening on one side of the storage compartment, and a lower terminal block is installed in the opening.

[0009] The opening on one side of the placement compartment is used to install the lower terminal block, providing installation limits for the lower terminal block.

[0010] Furthermore, the lower terminal block includes a vertical lower terminal support plate with a recessed slot. The front side of the support plate has two recessed lower terminal limiting grooves with a fixing screw hole in the middle. The front end of the lower terminal limiting groove is a forward-extending lower fixing plate with a through hole for fixing.

[0011] The lower terminal block is secured to the opening by the lower terminal block stand plate at its tail end, thus completing the limiting installation. The lower terminal block is used to limit the installation of the lower copper busbar.

[0012] Furthermore, there is also an opening on the other side of the storage compartment, and an upper terminal block is installed in the opening.

[0013] The opening on the other side of the placement compartment is used to install the upper terminal block, providing installation limits for the upper terminal block.

[0014] Furthermore, the upper surface of the upper terminal block has multiple upper terminal limiting grooves, the middle of the upper terminal limiting grooves has a fixing screw hole, and both ends of the upper terminal block have vertical upper terminal slots and upper fixing plates.

[0015] The upper terminal block is secured to the opening by the upper terminal block upright plates at both ends, thus completing the limiting installation. The upper terminal block is used to limit the installation of the upper copper busbar.

[0016] By means of the above solution, the present invention has at least the following advantages: This positioning-free capacitor mounting structure has a housing compartment for the capacitor mounting area. After the corresponding lower copper busbar, core, upper copper busbar, lower terminal block and upper terminal block are placed into the housing compartment, they are then fixed and finally potted. This effectively improves the capacitor mounting efficiency and reduces the overall volume.

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] See Figures 1-4 This positioning-free capacitor mounting structure uses a housing 1 for mounting capacitor components. A recessed mounting compartment 2 is located in the center of the housing 1. The insulating frame 3 of the capacitor structure is first placed inside the mounting compartment 2. From bottom to top, using the insulating frame 3 as the base, the lower copper busbar 4, the core 5, and the upper copper busbar 6 are sequentially arranged. The lower copper busbar 4 and the upper copper busbar 6 are respectively fixedly connected to the lower terminal block 7 and the upper terminal block 8. Finally, the lower terminal block 7 and the upper terminal block 8 are fixed inside the housing 1, completing the fixing process. Finally, the fixed capacitor structure is potted with adhesive, thus completing the installation and fixing of the capacitor assembly. This improves the installation efficiency of the capacitor assembly and reduces the overall structure volume.

[0028] See Figure 3 and Figure 5 The opening on one side of the mounting compartment 2 is for installing the lower terminal block 7, which facilitates the lead-out of the lower copper busbar 4 connected to the lower terminal block 7.

[0029] See Figure 5 The rear end of the lower terminal block 7 is the lower terminal stand plate 9. The two ends of the lower terminal stand plate 9 have slots that can be inserted into the corresponding installation position of the placement compartment 2 to complete the locking and fixing. The lower terminal limiting groove 10 of the lower terminal block 7 is used to place the pins led out from the lower copper busbar 4. After placement, the bolts are screwed into the screw holes of the lower terminal limiting groove 10 to complete the fixing of the pins of the lower copper busbar 4. The lower fixing plate 11 at the front end of the lower terminal block 7 is used to contact the outer shell 1. The through holes on the lower fixing plate 11 are matched with the corresponding screw holes and bolts to complete the fixed installation of the lower terminal block 7.

[0030] See Figure 4 and Figure 6 The opening on the other side of the placement compartment 2 is for installing the upper terminal block 8, which facilitates the lead-out of the upper copper busbar 6 connected to the upper terminal block 8.

[0031] See Figure 6 The upper terminal block 8 has recessed upper terminal slots 13 on both sides. The upper terminal slots 13 cooperate with the inner sidewall of the opening of the mounting compartment 2 to provide guidance for fixing the upper terminal block 8. There are multiple upper terminal limiting slots 12 on the surface of the upper terminal block 8. These upper terminal limiting slots 12 are used to fix the pins of the upper copper busbar 6. There are multiple screw holes in the middle of the upper terminal limiting slots 12. When fixing the pins of the upper copper busbar 6, it is only necessary to use the corresponding bolts to pass through the through holes of the pins of the upper copper busbar 6 and tighten them. There are also integrally formed upper fixing plates 14 on both sides of the upper terminal block 8. The upper fixing plates 14 have through holes. These through holes are connected to the corresponding screw holes on the outer shell 1. When fixing, the bolts pass through the copper holes and are screwed into the screw holes to complete the fixing.

[0032] Finally, the potting process is performed to complete the encapsulation of the lower copper busbar 4, the core 5, and the upper copper busbar 6.
