Improved capacitor base

Abstract

The invention discloses an improved capacitor base. The improved capacitor base comprises a base body, a plurality of arc-shaped bosses are arranged at the top of the base body, two symmetrical electrode extraction holes are arranged in the middle of the base body, electrode lead grooves are arranged at the bottom of the base body, one ends of the electrode lead grooves are communicated with the electrode extraction holes, the other ends of the electrode lead grooves are communicated with an outer edge of the base body, a plurality of semispherical bumps which are distributed evenly and have the equal size are arranged on the inner arc-shaped surfaces of the arc-shaped bosses, and an incircle cavity formed by the semispherical bumps is fitted with the excircle of a chip capacitor; and two tin melting channels are also arranged at the bottom of the base body. According to the improved capacitor base, the fixing of the capacitor is enhanced, the shaking of the capacitor in high-speed automatic assembling process is reduced, and a vibration reduction effect is achieved; and the phenomenon that the break between the two pins is caused by the flowing of the molten soldering tin when the pins and a circuit board are subjected to tin soldering and then blow-welding can be effectively avoided, so that the normal use of the whole circuit board can be ensured.

Description

technical field [0001] The invention relates to an improved capacitor base, in particular to a base for loading chip capacitors, and belongs to the technical field of electronic components. Background technique [0002] The capacitor base is an important accessory of the SMD aluminum electrolytic capacitor. It plays a supporting and heat insulating role for the SMD capacitor. The large electrolytic capacitor has a large volume and may shake during transportation or during high-speed automatic assembly. , it is easy to cause the lead wire to be broken. Since there is no isolation measure between the two pins of the chip aluminum electrolytic capacitor, when reflow blowing soldering is performed after soldering with the circuit board, it is easy to cause the melted solder to flow from the base side to the On the other side, a short circuit occurs between the two polarities of the capacitor, which affects the normal and practical use of the entire circuit board.
