Gradual changing square resistance metal metallized safety film, the cover board include capacitor cover plate ontology and binding post, and the cover board body is equipped with
With the mutually matched groove of binding post, the wiring column outer wall and wiring groove inner wall are provided with the screw thread being mutually matched, institute
The bottom for the cover board body stated is provided with the low metalwork of contact resistance, and described metalwork one end is logical with top low capacity capacitance
It crosses soldering to be attached, the other end is attached by electric arc rivet welding.
Further, the depth of the wiring groove is equal to the height of binding post.
Further, the quantity of the binding post and wiring groove is equal.
The present invention is effective to be：It is designed using the double-deck core structures, using low capacity capacitive absorption high-frequency harmonic, using big
Capacity is realized the feature that condenser voltage rate of climb is high, high frequency performance is good, energy storage density is big, is had by high current
Very high sensitivity, and self-healing can be effectively isolated self-healing breakdown part, compared with prior art, covering plate structure of the invention is machine
