Description
Technical field
The present invention relates to thin film capacitor manufacturing metallized film materials, more particularly to a kind of composite construction
Safety diaphragm.
Background technology
For thin film capacitor because it is used widely with good resistance to pressure and self-healing property, metallized film is thin-film electro
The important materials of container production manufacture, by high purity metal（Such as AL, ZN）It melts, evaporate under high vacuum state, being deposited to Jie
On matter basement membrane, the film after medium membrane surface forms one layer of very thin coat of metal is exactly metallized film；Existing market
The metal metallized safety film generally used is to be separated into many with very narrow gap strip epilamellar metallization coating is vaporized on
More fritters plates layer unit, and each small plating layer unit has had fuse（Fuse）The filament of effect is connected, this knot
When on the film of structure if any electric weak point breakdown, disruptive discharge electric current can be thin the metal connected outside the small coating cell block where the point
Silk is blown, and is made to be isolated with integral capacitor device electrode plate with the small plating layer unit at electric weakness, is formed an insulation layer and reach
Self-healing can reduce the self-healing time of thin film capacitor, reduce the damage to medium, though and integral capacitor device has lost and is isolated
The capacitance of small plating layer unit, can but continue to keep normal work, to make capacitor improve operating voltage and service life, specially
It is exactly such a metal metallized safety film that sharp document CN105428063A is disclosed.But there is disadvantages for metal metallized safety film：1.
Because coating is divided into many plating layer units, the pole plate that many gap strips account for about 5-10% effective using many gap strips
Area is also unfavorable for the volume miniaturization of thin film capacitor so the manufacturing cost of thin film capacitor increases；2. when have breakdown and
When self-healing occurs, although being isolated the area very little of small plating layer unit, the phase compared with normally breakdown self-healing point plate areas
Difference is very big, so capacity loss values are more great many times than common metal membrane capacitance standard index value, it is effective that there are layer electrodes
Area utilization low defect certainly will increase the volume of capacitor in this way.
Invention content
The purpose of the present invention is being directed to the deficiencies in the prior art, a kind of safety diaphragm of composite construction is provided, is had both
The pole plate effective area of the advantages of common safe metalized film and common metal film, thin film capacitor manufacture increase, when having
Capacitance loss rate is low when breakdown occurs with self-healing, and the volume for being conducive to thin film capacitor minimizes.
Technical solution：
To achieve the above object, present invention employs following technical schemes：A kind of safety diaphragm of composite construction, including basement membrane, steaming
It is in that the metal coated strip of longitudinal branch and blank stay sideband to be plated in basement membrane vapor deposition face；The metal coated strip includes that coating thickeies
Band, universal metalized film coating band, safe metalized film coating band；The safe metalized film coating band is provided with to be arranged in matrix
The plating layer unit of row；By playing fuse between each plating layer unit（Fuse）The filament equipotential of effect is electrically connected
It connects.
Preferably, the width ratio of the safe metalized film coating band and universal metalized film coating band is 1：1~1.2.
Compared with prior art, the present invention haing the following advantages：
Universal metalized film coating band and safe metalized film coating band are vaporized on same basement membrane, it is made to have both commonly
The advantages of safe metalized film and common metal film, the safety diaphragm of composite construction is formed, one layer of conventional use can be substituted
Safety diaphragm and one layer of common metal film collocation wound capacitor fuse technology mode；Using the peace of two layers of composite construction of the present invention
Full film layer folds misalignment wound capacitor fuse, and pole plate effective area increases, and when having breakdown and self-healing occurs, capacitance loss rate is low,
It is minimized conducive to the volume of thin film capacitor.
