Background

For household appliance capacitors, the requirements of common enterprises meet the requirements of GB/T3667.1, a safety film is a common safety component of the capacitor, and the requirements of the capacitor mean that the capacity check and the explosion-proof check of the safety film must reach the standard. However, the explosion-proof capacitor sold in the market at present mainly has two defects of unreliable explosion-proof performance and unstable and poor consistency of the service life of the capacitor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a netted rupture disk, the explosion-proof performance and the experimental GB/T3667.1 requirement that accords with of self-healing nature of this rupture disk to overcome prior art's not enough.

The technical proposal of the utility model for solving the technical problem is that: a netted safety film comprises a plastic film, wherein a metal coating is arranged on the surface of the plastic film, and the netted safety film is characterized in that: the metal coating divides the plastic film into a grid part square resistance area and a grid edge part, the grid edge part is respectively arranged at two sides of the grid part square resistance area, the grid part square resistance area and the grid edge part are separated by a plurality of grid square resistances, if no grid strip is plated at the edge part of a dry grid, two adjacent grid edge parts are connected in a safety way by the grid edge part, the grid part square resistance area comprises a plurality of grid square resistances, a single grid square resistance is arranged at an angle of 45 degrees, and adjacent grids are arranged in a staggered mode by a single grid square resistance and a double grid square resistance, so that a row of triangular grids is formed on the edge adjacent to the grid edge part; the grid square resistors are separated by blank net edges, and each blank net edge is provided with a grid part safety.

The middle part of the grid part square resistance area is provided with a screen belt, and the screen belt extends along the extension direction of the membrane, so that the grid part square resistance area is divided into an upper part and a lower part.

Three rows of grid square resistors which are arranged in a diamond shape are distributed in the grid square resistor area, and the upper part and the lower part of the grid square resistor area are symmetrical.

The utility model has the advantages that:

compared with the prior art, the utility model provides a netted safety film hinders by the side with, net limit portion constitutes, hinders regional centre in both sides with the screen area setting, and this structure is two electric capacities of staying the limit and pairing two strings of structures in for, can become the film thickness 3.5um by original 7.0um attenuation. Thereby reducing the volume of the capacitor and enabling the capacitor to be more miniaturized.

The specific meaning of the above terms in the present invention can be understood in specific cases for those skilled in the art.

Referring to fig. 1, a netted safety film comprises a plastic film and a metal coating on the surface of the plastic film, wherein the plastic film is divided into a grid part square resistance area 1 and a grid edge part 2 by the metal coating, the grid edge part 2 is respectively arranged on two sides of the grid part square resistance area 1, the grid part square resistance area 1 and the grid edge part 2 are divided by grid strips 4 which are not plated on the edge part of a dry net, and two adjacent grid edge parts are connected by grid edge part safety 5 which is not plated on the edge part of the dry net. The grid bars which are not plated on the net edge part are rectangular, and the gaps formed by the grid bars which are not plated on the adjacent net edge part are filled with the net edge part insurance formed by the metal plating layer.

Three rows of grid square resistances 11 which are arranged in a diamond shape are distributed in the grid square resistance area 1, a single grid square resistance 11 is arranged at an angle of 45 degrees, and adjacent rows of grids are arranged in a staggered mode in a single-double-number grid mode, so that a row of triangular grids 12 is formed on the side adjacent to the net edge. The four blank net edges 13 enclose an area of the grid square resistor 11, and the two blank net edges 13 enclose a triangular grid 12. Each blank net edge 13 is provided with a grid part safety 15, and when the current is overlarge, the safety strip is melted off, so that the metal coating is disconnected with other layers, and the safety performance is ensured.
