Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of capacitors, in particular to a solid electrolytic capacitor. Background Art
[0002] Electrolytic capacitors are generally divided into polar and non-polar types, but sometimes non-polar ones are also called bipolar electrolytic capacitors. Polar electrolytic capacitors, that is, those with negative electrodes, generally have positive electrodes composed of oxide film metal substrate materials, while the negative electrode is composed of electrolytes and positive metals. Bipolar electrolytic capacitors can be understood as capacitors formed by directly connecting two electrolytic capacitor cathodes or anodes in series. The characteristic of this type of capacitor is that there is no distinction between positive and negative.
[0003] Existing solid electrolytic capacitors generally use aluminum casings, which are easily deformed when subjected to pressure. Repairing them after damage requires removing the entire capacitor and then re-fixing it, but this is time-consuming and labor-intensive. Therefore, we propose a solid electrolytic capacitor. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
[0022] A solid electrolytic capacitor provided by some embodiments of the present utility model is described below in conjunction with the accompanying drawings.
[0023] Combination Figure 1-2 As shown, the utility model provides a solid electrolytic capacitor, including: a capacitor component 100 and a connecting mechanism 200; the capacitor component 100 includes a shell 110 and a capacitor core 120 arranged in the shell 110, the connecting mechanism 200 is arranged on the capacitor component 100, and the capacitor component 100 also includes a heat dissipation hole 130 opened on the shell 110, which can facilitate the heat dissipation of the capacitor core 120.
[0024] Among them, the connecting mechanism 200 includes a connecting mechanism arranged on the shell 110 and the capacitor core 120 and a fastening mechanism 300 installed on the shell 110; the connecting mechanism includes an insulating block 210 installed at the bottom of the shell 110, a connecting block 220 embedded in the insulating block 210, a lead 230 connected to the outside of the connecting block 220, a connecting wire 240 fixed to the bottom of the capacitor core 120 and arranged corresponding to the connecting block 220, and a docking groove 250 respectively opened in the connecting block 220 and the connecting wire 240. Through the connecting mechanism 200, the capacitor core 120 can be directly placed in the shell 110, and the connecting block 220 and the connecting wire 240 are used to complete the docking, and the docking groove 250 on the connecting block 220 can make the end of the connecting wire 240 pressed when entering, and then deformed under the action of the docking groove 250 in the connecting wire 240, and finally make the outer side of the connecting wire 240 close to the inner side of the connecting block 220, and the connection is more fully and stably.
[0025] Specifically, the docking groove 250 is a trapezoidal groove structure, which can make the connecting line 240 deform inward when pressed downward, and then move downward closely along the inner wall of the connecting line 240 to fully complete the docking.
[0026] Furthermore, the fastening mechanism 300 includes an end cover 310 disposed on the top of the housing 110, a screw hole 320 opened in the middle of the end cover 310, a screw rod 330 threadedly connected to the screw hole 320, a pressing block 340 sleeved on the inner end of the screw rod 330, a protective frame 350 fixed to the screw rod 330 and covering the outside of the capacitor core 120, a threaded ring 360 fixed to the inner side of the bottom of the protective frame 350, and a screw threaded ring 360 disposed on the outer side of the insulating block 210. The external thread 370 is threadably connected to the threaded ring 360 on the side. Through the fastening mechanism 300, the protective frame 350 can be directly placed into the outer shell 110, and then the end cover 310 is placed on the end of the outer shell 110. At this time, the screw 330 is turned to screw the threaded ring 360 onto the external thread 370 to complete the fixation. At this time, the pressure block 340 is also pressed on the capacitor core 120, which has a pressing and fixing effect on the connection of the capacitor core 120 below, thereby ensuring the stability of the capacitor core 120.
[0027] Specifically, a buffer pad 351 is fixed to the outer side of the protection frame 350 , which can play a buffering role when the housing 110 is subjected to external pressure, and cooperates with the protection frame 350 to play a variety of protective effects on the capacitor core 120 .
[0028] Furthermore, the pressing block 340 is made of a soft rubber pad, which can play a tightening role without causing damage to the capacitor core 120, which is more reasonable.
[0029] The working principle and use process of the utility model are as follows: first, the capacitor core 120 is directly placed in the shell 110, and then the capacitor core 120 is appropriately pressed down, and the docking groove 250 on the connecting block 220 can be used to make the end of the connecting wire 240 be compressed when entering, and then deform under the action of the docking groove 250 in the connecting wire 240, so that the outer side of the connecting wire 240 is close to the inner side of the connecting block 220, forming an inclined surface, and then the protective frame 350 is directly placed in the shell 110, and then the end cover 310 is placed on the end of the shell 110, and at this time, the screw 330 is turned to screw the threaded ring 360 on the external thread 370 to complete the fixation, and at this time, the pressing block 340 is also pressed on the capacitor core 120, which has a pressing and fixing effect on the connection of the capacitor core 120 below.
