Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and in particular to a capacitor core that is easy to assemble and a capacitor thereof. Background Technology

[0002] Film capacitors are capacitors constructed by overlapping metal foil as electrodes with plastic films such as polyethylene, polypropylene, polystyrene, or polycarbonate at both ends and then winding them into a cylindrical shape. After the capacitor core is wound, it needs to be fixed inside the casing by potting epoxy resin and connected to the outside of the casing via busbars to achieve sealing and facilitate connection. In existing technology, the busbars are usually connected to the electrodes of the capacitor core by welding. This structure causes current to concentrate at a small number of solder joints, resulting in excessive localized heating of the capacitor core. At the same time, welding increases the capacitor manufacturing process and raises production costs. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a capacitor core and capacitor that are easy to assemble. The first conductive block is stably fixed to the capacitor core through the connecting part, which avoids excessive heat generation caused by current concentration and improves the working stability and service life of the capacitor.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] In a first aspect, this application provides a capacitor core that is easy to assemble, comprising: a main body, a conductive portion, and a connecting portion. The conductive portion includes a first conductive block connected to the main body and a second conductive block extending outward. The connecting portion includes a first spray layer and a second spray layer. The first spray layer is located between the first conductive block and the main body. The first conductive block is provided with a plurality of conductive sheets, and a notch is provided between adjacent conductive sheets. The second spray layer covers the conductive sheets and the notch to fix the first conductive block to the outside of the first spray layer.

[0006] The aforementioned easy-to-assemble capacitor core has at least the following beneficial effects: By providing conductive and connecting parts, the second spray layer can stably fix the conductive sheet to the electrode of the main body and connect it to external equipment through the second conductive block, effectively increasing the contact area between the first conductive block and the main body, improving the connection stability between the conductive part and the main body, eliminating the welding production step, and improving the production efficiency of the easy-to-assemble capacitor core; by providing the main body and connecting parts, the first spray layer is located between the first conductive block and the main body, ensuring the conductivity between the main body and the conductive part, and improving the working stability and service life of the capacitor core.

[0007] Furthermore, multiple conductive sheets are distributed parallel to each other at the lower end of the conductive part. By setting multiple parallel conductive sheets, the contact area between the first conductive block and the main body can be effectively increased, avoiding concentrated heat generation between the first conductive block and the main body, which would affect the working stability of the capacitor core and improve the load capacity of the easily assembled capacitor core.

[0008] Furthermore, the second conductive block is located on one side of the conductive portion, and the conductive sheets are evenly distributed at the lower end of the conductive portion. This structure ensures that the second conductive block can be flexibly connected to the outside of the main body, and also ensures that the conductive sheets can stably and evenly contact the electrodes of the main body, improving the working stability and ease of use of the easily assembled capacitor core.

[0009] Furthermore, the thickness of the conductive sheet is less than the thickness of the second conductive block. This structure ensures that the second sprayed layer can stably adhere to the conductive sheet and the notch, and stably connect the first conductive block to the electrode of the main body, improving the structural integrity of the easily assembled capacitor core.

[0010] Furthermore, the first sprayed layer is distributed on both sides of the main body to form two electrodes of the main body. This structure ensures that the first sprayed layer can fully cover both ends of the main body, facilitating the rapid and stable fixing of the conductive part and the second sprayed layer onto the main body, thereby improving the production efficiency of easily assembled capacitor cores.

[0011] Furthermore, the thickness of the second coating layer is greater than that of the first coating layer. This structure ensures that the second coating layer can stably fix the conductive sheet to both ends of the main body, preventing the second coating layer from falling off, saving coating material, and reducing the production cost of the easily assembled capacitor core.

[0012] Furthermore, the second sprayed layer is rectangular. This structure ensures that the second sprayed layer can completely cover the first conductive block, so that the conductive sheet is stably fixed at both ends of the main body, avoiding the conductive part from becoming loose from the main body, and improving the structural integrity of the capacitor core that is easy to assemble.

[0013] Furthermore, the length of the first conductive block is greater than the length of the second conductive block. This structure facilitates the flexible connection of the second conductive block to external devices and effectively increases the contact area between the first conductive block and the main body, thereby improving the flexibility and stability of the easily assembled capacitor core.

[0014] Furthermore, the first conductive block and the second conductive block are integrally formed from copper busbars. Copper busbars are an indispensable conductive material for power distribution installation wires. The integral forming of the first conductive block and the second conductive block from copper busbars ensures the conductivity of the conductive parts and also reduces the production cost of the capacitor core, which is easy to assemble.

[0015] In a second aspect, a capacitor includes a capacitor core as described above for easy assembly.

[0016] The beneficial effects of the above-mentioned capacitor are as follows: By setting the conductive part and the connecting part, the second spray layer can stably fix the conductive sheet to the electrode of the main body and connect it to the external device through the second conductive block, effectively increasing the contact area between the first conductive block and the main body, improving the connection stability between the conductive part and the main body, eliminating the welding production step, and improving the production efficiency of the easily assembled capacitor core; by setting the main body and the connecting part, the first spray layer is located between the first conductive block and the main body, ensuring the conductivity between the main body and the conductive part, and improving the working stability and service life of the capacitor core; by setting multiple parallel conductive sheets, the contact area between the first conductive block and the main body can be effectively increased, avoiding concentrated heat generation between the first conductive block and the main body, which would affect the working stability of the capacitor core and improve the load capacity of the easily assembled capacitor core.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

During assembly, the conductive portion 200 needs to be soldered to both sides of the main body 100 to form solder joints 400.

The second spray layer 320 covers the conductive sheets 211 and the notch 212 so that the first conductive block 210 is fixed to the outside of the first spray layer 310.

[0026] The aforementioned easy-to-assemble capacitor core has at least the following beneficial effects: By providing the conductive part 200 and the connecting part 300, the second spray layer 320 can stably fix the conductive sheet 211 to the electrode of the main body 100, and connect it to external devices through the second conductive block 220, effectively increasing the contact area between the first conductive block 210 and the main body 100, improving the connection stability between the conductive part 200 and the main body 100, eliminating the welding production step, and improving the production efficiency of the easy-to-assemble capacitor core; By providing the main body 100 and the connecting part 300, the first spray layer 310 is located between the first conductive block 210 and the main body 100, ensuring the conductivity between the main body 100 and the conductive part 200, and improving the working stability and service life of the capacitor core.

[0027] In another embodiment, multiple conductive sheets 211 are distributed parallel to each other at the lower end of the conductive portion 200. By providing multiple parallel conductive sheets 211, the contact area between the first conductive block 210 and the main body 100 can be effectively increased, avoiding concentrated heat generation between the first conductive block 210 and the main body 100, which would affect the working stability of the capacitor core and improve the load capacity of the easily assembled capacitor core.

[0028] In another embodiment, the second conductive block 220 is located on one side of the conductive portion 200, and the conductive sheets 211 are evenly distributed at the lower end of the conductive portion 200. This structure ensures that the second conductive block 220 can be flexibly connected to the outside of the main body 100, and also ensures that the conductive sheets 211 can stably and evenly contact the electrodes of the main body 100, thereby improving the working stability and ease of use of the easily assembled capacitor core.

[0029] In another embodiment, the thickness of the conductive sheet 211 is less than the thickness of the second conductive block 220. This structure ensures that the second spray layer 320 can be stably attached to the conductive sheet 211 and the notch 212, and stably connects the first conductive block 210 to the electrode of the body 100, thereby improving the structural integrity of the easily assembled capacitor core.

[0030] In another embodiment, the first spray layer 310 is distributed on both sides of the main body 100 to form two electrodes of the main body 100. This structure ensures that the first spray layer 310 can fully cover both ends of the main body 100, which facilitates the quick and stable fixing of the conductive part 200 and the second spray layer 320 onto the main body 100, thereby improving the production efficiency of the easily assembled capacitor core.

[0031] In another embodiment, the thickness of the second spray layer 320 is greater than the thickness of the first spray layer 310. This structure ensures that the second spray layer 320 can stably fix the conductive sheet 211 to both ends of the main body 100, preventing the second spray layer 320 from falling off, saving spraying material, and reducing the production cost of the easily assembled capacitor core.

[0032] In another embodiment, the second spray layer 320 is rectangular. This structure ensures that the second spray layer 320 can completely cover the first conductive block 210, so that the conductive sheet 211 is stably fixed at both ends of the main body 100, avoiding the situation where the conductive part 200 is loosened from the main body 100, and improving the structural integrity of the capacitor core that is easy to assemble.

[0033] In another embodiment, the length of the first conductive block 210 is greater than the length of the second conductive block 220. This structure facilitates the flexible connection of the second conductive block 220 to external devices and also effectively increases the contact area between the first conductive block 210 and the main body 100, improving the flexibility and stability of the easily assembled capacitor core.

[0034] In another embodiment, the first conductive block 210 and the second conductive block 220 are integrally formed from copper busbars. Copper busbars are an indispensable conductive material for power distribution installation wires. The integral forming of the first conductive block 210 and the second conductive block 220 from copper busbars ensures the conductivity of the conductive part 200 and also reduces the production cost of the capacitor core, which is easy to assemble.

[0035] This utility model embodiment also provides a capacitor, including the capacitor core described above that is easy to assemble.

[0036] In the production process of the easily assembled capacitor core in this embodiment, firstly, a conductive part 200 of corresponding size is selected according to the specifications of the capacitor core 300. The upper and lower ends of the conductive part 200 are respectively provided with a second conductive block 220 and a first conductive block 210. The first conductive block 210 is provided with a plurality of conductive sheets 211, and a notch 212 is provided between adjacent conductive sheets 211. Next, metal is sprayed on both sides of the capacitor core 300 to form a first spray layer 310 to form two electrodes of the main body 100. Then, the lower part of the conductive part 200 is fixed to the outside of the first spray layer 310, so that the conductive sheets 211 are electrically connected to the electrodes of the main body 100. Finally, metal is sprayed again on the outside of the conductive sheets 211 and the notch 212 to form a second spray layer 320, and the first conductive block 210 is stably fixed to the first spray layer 310, so that the conductive part 200 can lead the two electrodes of the main body 100 to the upper part of the main body 100 through the first conductive block 210 and the second conductive block 220. This completes the production of an easily assembled capacitor core. The entire process is controllable and efficient, eliminating the welding process between the main body 100 and the conductive part 200 in traditional capacitor core manufacturing, thus ensuring the production efficiency of the easily assembled capacitor core. During use, current flows into or out of the two electrodes of the main body 100 through the conductive sheet 211. Because multiple conductive sheets 211 are arranged parallel and evenly at the lower end of the conductive part 200, the current is distributed at multiple points through the connection point between the conductive sheet 211 and the first spray layer 310, reducing the current at a single point, decreasing heat generation, and avoiding current concentration and increased heat generation. This improves the working stability and load capacity of the easily assembled capacitor core and its capacitor.

[0037] As can be seen from the above description, the easily assembled capacitor core and its capacitor of this utility model, by setting the conductive part 200 and the connecting part 300, the second spray layer 320 can stably fix the conductive sheet 211 to the electrode of the main body 100, and connect to external devices through the second conductive block 220, effectively increasing the contact area between the first conductive block 210 and the main body 100, improving the connection stability between the conductive part 200 and the main body 100, eliminating the welding production step, and improving the production efficiency of the easily assembled capacitor core; by setting the main body 100 and the connecting part 300, the first spray layer 310 is located between the first conductive block 210 and the main body 100, ensuring the conductivity between the main body 100 and the conductive part 200, improving the working stability and service life of the capacitor core; by setting multiple parallel conductive sheets 211, the contact area between the first conductive block 210 and the main body 100 can be effectively increased, avoiding concentrated heat generation between the first conductive block 210 and the main body 100, which would affect the working stability of the capacitor core, and improving the load capacity of the easily assembled capacitor core.
