Abstract
The invention relates to a metallic safe membrane capacitor with double fuse and high safety, an upper positioning sleeve and a lower positioning sleeve are mounted in the casing, cores are arranged between the positioning sleeves; an explosion-proof block is arranged above the upper positioning sleeve, a cap body is arranged above the explosion-proof block. A lower end of a terminal on the cap body is connected with a rivet, an explosion-proof line welded on the rivet is connected with a metal block by an through-hole on the explosion-proof block. The corresponding through-hole is arranged on the upper positioning sleeve, a wire leaded out on the core is welded on the metal block after passing through the through-hole of the upper positioning sleeve, thereby leading out two electrodes of the capacitor; the cap body is pressed in the casing by the curled edge outwards on the casing. The cores are packed between the upper positioning sleeve and the lower positioning sleeve by the epoxy resin to solve leakage problem of the dipping material. The cores use two layers of metallic safe membranes, each layer of the metallic safe membrane divides into a gridding area and a II-shaped area along a longitudinal center line, which solves the technical problem that the capacitor cores coiled by common metallic membranes are not propitious to the safety of the capacitor.

The metallized safety film capacitor of described double-safety high-safety is characterized in that: this fuse has the metal metallized safety film of two stacked volumes, and every layer of metal metallized safety film longitudinally center line divided grid regions and ∏ shape district; In grid regions, coating is divided into many small sizes unit by narrower space bar, has narrow shape plated film contact to link to each other between the adjacent small size unit; The edge of ∏ shape district one side is provided with the white edge of leaving a blank; The metal metallized safety film of two stacked volumes, the ∏ shape district on upper strata is corresponding with the grid regions of lower floor, and the grid regions on upper strata is corresponding with the ∏ shape district of lower floor; One side of joining in grid regions and ∏ shape district is provided with the additional clearance groove is separated by, and has the narrow shape plated film contact between the additional clearance groove to link to each other between ∏ shape district and adjacent small size unit.
The metallized safety film capacitor of described double-safety high-safety is characterized in that: this capacitor body by epoxy encapsulation between upper and lower positioning sleeve and shell.
The metallized safety film capacitor of described double-safety high-safety is characterized in that: fuse adopts two-layer safety diaphragm, and in the ∏ of safety diaphragm shape district, coating is formed large stretch of ∏ cell block by space row culture horizontal partition.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention can avoid because the maceration extract seepage that the crimp quality problem causes;
2, the present invention uses the safety film capacitor fuse with special construction, has further improved the security performance of capacitor.
