AI Technical Summary

Technical Problem

When the leads of existing capacitors are connected to the capacitor body, the effective contact area of ​​the soldering is limited, which makes the solder joints prone to cracking and the leads to fall off. In addition, the conductive area is insufficient and the current carrying capacity is poor.

Method used

The design adopts a lead body with the connecting section extending circumferentially around the center of the lead section and surrounding the outer perimeter, forming a ring or polygonal contact surface, making multiple contacts with the capacitor end face, increasing the contact area and dispersing stress, and using copper material to ensure conductivity and connection strength.

Benefits of technology

It improves the connection strength between the lead and the capacitor, reduces the risk of detachment due to external forces, enhances the current carrying capacity of the current conduction path, and reduces heat loss and uneven current density.

Abstract

The utility model discloses a kind of lead structures of capacitor, including lead body, the lead body includes connecting section and lead-out section, the lead-out section is connected with the connecting section, and it extends along its own axial direction;The end of the connecting section is connected with the end of the lead-out section, the other end of the connecting section is peripherally extended around the center of the lead-out section, and is surrounded in the periphery of the lead-out section.A kind of capacitor, including core element and the lead structure of the capacitor described, the connecting section is electrically connected with the core element.The lead structure is electrically connected with the end surface of capacitor by connecting section, since the connecting section of lead body is peripherally extended around the center of lead-out section, and is surrounded in the periphery of the lead-out section, so that the contact area of lead structure and capacitor increases, reduces the risk of lead drop;At the same time, effectively reduce contact resistance, reduce heat loss when current transmission, enhance overcurrent capacity.
