Capacitor Insulated Terminal Cover

Abstract

The invention discloses a capacitor insulating terminal cover, which includes a cover plate, a connecting terminal and a power cord, the connecting terminal includes an "L" shaped connecting part and a connecting cylinder, the connecting cylinder is in the shape of a waist drum with a thick middle, and the cover plate There is a connection hole on the top, the connection hole is the same drum shape as the connection cylinder, the wiring part includes a vertical part connected with the external wire and a horizontal part connected with the connection cylinder, the horizontal part is provided with A soldering hole coaxially arranged on the connecting cylinder, the bottom end of the connecting cylinder is provided with a bending portion extending toward the center of the connecting cylinder; the conductive core of the power cord extends into the connecting cylinder through the bending portion, the The conductive core of the power cord and the connecting barrel are fixed by soldering filling. The capacitor insulating terminal cover of the present invention can avoid the problem that the soldering part is easy to fall off from both ends of the connecting cylinder after aging; the conductive core body of the power cord is fixed by the bending part, avoiding the complicated process of auxiliary fixing of the power cord, and improving the welding efficiency .

Description

technical field [0001] The invention belongs to the technical field of capacitors, in particular to a capacitor insulating terminal cover. Background technique [0002] Usually, the capacitor insulating terminal cover is formed by fixing the quick-connect terminal on the upper surface of the cover made of insulating material by rivets, and the rivet fixes the welding piece on the lower surface of the cover at the same time, through the welding piece and the inside of the capacitor. Solder the power cord. This traditional structure uses many parts with poor consistency, which is easy to cause large contact resistance, and the welding area of ​​the welding piece and the internal power line is small, which is easy to fall off or false welding, and when the welding piece is riveted, it is easy to cause The larger the spacing, the larger the creepage distance of the power supply. The patent application document with the application number CN201410441563.4 protects a capacitor i...

Problems solved by technology

This traditional structure uses many parts with poor consistency, which is easy to cause large contact resistance, and the welding area of ​​the welding piece and the internal power line is small, which is easy to fall off or false welding, and when the welding piece is riveted, it is easy to cause Large spacing, resulting in large creepage distance of the power supply

The patent application document with the application number CN201410441563.4 protects a capacitor insulating terminal cover, but this structure has the following problems: (1) Due to the soft quality of the internal power cord, the inner core of the power cord and the connection There is a gap between the barrels. If the internal power line is not fixed, the internal power line will fall during soldering and the welding will not be firm; (2) The use environment of the capacitor is complicated, and it is often bumped or bumped. Once the thin waist drum-shaped soldering part is aged, it is easy to fall off from both ends of the connecting cylinder, which will affect the conductivity of the capacitor
