Entire terminal cover explosion proof construction for capacitor

Abstract

The invention discloses a whole end cover blast-resistance structure of a capacitor. A blast-resistance sheet (2) is arranged on the end cover (1); a rivet (3) is adopted as a wire connecting terminal of the capacitor; a blast-resistance copper foil (4) is arranged on the surface of the blast-resistance sheet (2); and an end part, which faces to the inside of the capacitor, of the rivet (3) is connected with the blast-resistance copper foil (4). The invention adopts the novel, safer and more reliable whole end cover structure without the requirement of assembly, and the structure can be used directly when in assembly, so that the time and the cost for manufacturing the product are saved at the same time. Moreover, the whole end cover doesn't need welding, thereby saving tin wires and material costs.

Description

Technical field [0001] The invention belongs to the technical field of electronic products, and relates to an explosion-proof structure of a capacitor. More specifically, the invention relates to an explosion-proof structure of an integral end cover of a capacitor. Background technique [0002] The end cover of the traditional CBB65 capacitor is assembled by the end cover, explosion-proof wire, explosion-proof disc, and welding piece. [0003] In the process of assembling the end cap into a finished product, the explosion-proof wire must be welded to the end cap first, and then assembled with the explosion-proof disk. After positioning, the excessively long explosion-proof wire must be cut off (the reason for the excessively long explosion-proof wire Yes: The high temperature generated during welding makes the explosion-proof wire very hot, so only put the length of the explosion-proof wire first, so that the welding personnel can operate it; after the welding is completed, manua...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned end cover structure requires a lot of manpower, material resources and financial resources during production, and the assembly time is long and the efficiency is low.

After two times of welding, a large amount of solder wire is used, and welding requires a lot of power consumption

In addition, solder particles are often splashed during soldering, and the splashed solder particles are easy to stick to the end cap of the finished product. When the end cap is assembled into a product, the solder particles will be left inside the product, which is very likely to cause Unqualified electrical performance of the product
