Problems solved by technology
In the traditional electrolytic capacitor assembly technology, when assembling the seal, the position of the waist is not on the rubber particles or the position of the waist is seriously shifted to the bottom or top of the plug (the rubber particles), so that the sealing is poor or even impossible. The role, which directly leads to the leakage of the electrolyte inside the electrolytic capacitor or the appearance of the bottom of the electrolytic capacitor, has a great impact on the life of the electrolytic capacitor

The invention discloses an electrolytic condenser. Sealing is carried out through a waist beam of a rectangular or trapezoid groove. The phenomenon that the beam waist and a plug (colloidal particles) relatively slide easily when the beam waist is formed cannot occur, the contact area between the beam waist and the plug is increased due to a large contact face existing at the bottom of the groove, the sealing performance of the electrolytic condenser is further improved, the possibility of electrolyte leakage is reduced, and the service life of the electrolytic condenser is prolonged. The invention further discloses a manufacturing method of the electrolytic condenser.
Description
technical field [0001] The invention relates to electronic components, in particular to an electrolytic capacitor and a manufacturing method thereof. Background technique [0002] With the development of light, thin and small electronic products, and the wide application of surface mount technology in electronic technology, correspondingly higher and higher requirements are put forward for the aluminum electrolytic capacitors used, and the volume of aluminum electrolytic capacitors is also increasing. develop in a smaller and smaller direction. The smaller the volume of the aluminum electrolytic capacitor, the higher the tightness of the internal structure of the capacitor is required, so the plug (colloid) that acts as a seal is also required to be thin. In the traditional electrolytic capacitor assembly technology, when assembling the seal, the position of the waist is not on the rubber particles or the position of the waist is seriously shifted to the bottom or top of th...
