[0002] Horn electrolytic capacitors are a type of electrolytic capacitor. Horn electrolytic capacitors are a popular name, and a more professional name is a conductive foil electrolytic capacitor; compared with other conductive needle electrolytic capacitors, horn electrolytic capacitors generally have large capacity and high voltage resistance.

[0003] Since the pin spacing of conventional bull-horn electrolytic capacitors is fixed, they can only be installed on circuit boards of fixed models. It is difficult to significantly change the spacing and install circuit boards with different docking hole widths, resulting in the problem that the pin spacing of conventional bull-horn electrolytic capacitors is inconvenient to adjust.

[0004] Therefore, we propose a plug-in welding pin adjustable horn capacitor to solve the above problems. Summary of the invention

During assembly, first pre-tighten the threaded button on the conductive pin, and then put the conductive pin on the conductive foot. Similarly, after assembling the two conductive pins and the threaded button, use the two threaded buttons to block each other to prevent the threaded button from rotating in the direction of excessive loosening, thereby preventing the threaded button from falling off. Then put the two insulating buckle shells on the capacitor body, buckle the spring buckle and the first buckle block, and use the conductive foot to press on the insulating buckle shell to facilitate the insulating buckle shell to remain on the capacitor body. During adjustment, slide the conductive pin along the conductive foot to adjust the spacing between the two conductive pins to match the gap of the target circuit board. After determining the gap, tighten the threaded button so that the threaded button presses the conductive foot downward to fix the conductive pin on the conductive foot. At the same time, use the insulating buckle shell to buckle the threaded button to prevent the threaded button from rotating, which is convenient for adjusting the spacing between the conductive pins and fixing the adjustment results of the conductive pins.

[0008] Preferably, the conductive foot comprises a guide block, a guide bar and a connecting bar, the guide bar is fixedly connected between the guide block and the connecting bar, and the guide block, the guide bar and the connecting bar are an integrated structure.

[0017] In summary, the technical effects and advantages of the present invention are as follows:

[0018] 1. During assembly, first pre-tighten the threaded button onto the conductive pin, and then put the conductive pin onto the conductive foot. Similarly, after assembling the two conductive pins and the threaded button, use the two threaded buttons to block each other to prevent the threaded button from rotating in an excessively loose direction, thereby preventing the threaded button from falling off.
