Description
Technical field
The utility model relates to field of electrical components, relates in particular to the thickened metalized polypropylene film capacitor in a kind of edge.
Background technology
Capacitor is the main electronic component that constitutes electronic circuit, uses during the capacitor of various materials and different structure developing and use.Wherein paper tinsel formula film capacitor occupies very big market; Paper tinsel formula film capacitor comprises two metal foil electrodes of being processed by aluminium foil; By separating as dielectric a slice plastic film, said plastic film can be polyester, polypropylene or Merlon etc. between these two electrodes; The thickness range of said plastic film is generally 2 μ m to 24 μ m; And the thickness of common said thin dielectric film as described below is derived from the rated voltage of capacitor, and the thickness range of said aluminium foil is 4 μ m to 9 μ m, and paper tinsel formula film capacitor can be reeled in two ways: sensing mode and no sensing mode are arranged; The inductance of paper tinsel formula film capacitor is by the width decision of said dielectric film, and this itself is a shortcoming, because in the big rated capacity device, the width of said dielectric film can increase; Thereby the inductance that causes this big rated capacity device unit to provide also can increase; When being applied to high voltage said is on the capacitor of insulator the time in theory, because the cause that paper tinsel formula electrode structure can't self-healing, this capacitor can be punctured by said electric charge, cause short circuit; And its exit is to draw through CP line box electrode aluminium foil welding, and welding resistance is big, and reliability is low.Our company research and development singly stay the limit metalizing polypropylene thin film capacitor, its capacitor body comprises the two-layer limit layer of metallized film of singly staying that is superimposed with each other, described be superimposed with each other two-layer singly stay the limit layer of metallized film stay the limit mutual dislocation; Have that volume is little, self-healing property is strong, good reliability, the strong advantage of little, the anti-pulse ability of loss, but along with complete electronic set the update continuous shortening in cycle and the compact raising that requires with digitlization; When singly staying limit metalizing polypropylene thin film capacitor work; Because the rising of temperature has brought very big loss, reliability of products can be poor; Anti-pulse shock ability; Particularly in alternating current-direct current occasions such as interference occasion, electronic arc-control device resonant circuit such as power supply cross-line road, because the line design length and the complexity of electronic product cause disturbing and clutter; Cause electronic circuit reliability ability and Electro Magnetic Compatibility poor, limited its application.
Summary of the invention
Not enough for solving prior art; The utility model provides little, inner little, the excellent flame of heating up of a kind of volume, reliability is high, anti-pulse shock performance is good, can bear overvoltage impacts; Be applied to interference occasions such as power supply cross-line road, the thickened metalized polypropylene film capacitor in edge of alternating current-direct current occasions such as the demagnetization arc extinguishing of the startup of unidirectional asynchronous motor, thyristor, relay.
The microminiature film capacitor.
The utility model adopts following technical scheme: the thickened metalized polypropylene film capacitor in edge; Comprise two lead-in wires, body and capacitor bodies; Described capacitor body comprises the two-layer limit layer of metallized film of singly staying that is superimposed with each other; The described limit layer of metallized film of singly staying comprises polypropylene-base rete and the aluminium lamination of vapor deposition on the polypropylene-base rete, and it is characterized in that: the edge of described aluminium lamination is provided with the thickening aluminium lamination.
Being of uniform thickness of the thickness of described thickening aluminium lamination and aluminium lamination is thick.
The length of described thickening aluminium lamination is 1 millimeter.
Spacing between said two lead-in wires is 7.5 millimeters.
The thickened metalized polypropylene film capacitor in the utility model edge, owing to be provided with the thickening aluminium lamination in the edge of aluminium lamination, thus reducing the contact resistance of end face, loss is little, thus it is little to reach temperature rise, and reliability is high, improves the anti-pulse shock performance of product.
The utlity model has following technique effect:
The thickened metalized polypropylene film capacitor volume in the utility model edge is little, inner little, the excellent flame of heating up, reliability is high, anti-pulse shock performance is good, can bear overvoltage impacts; Be applied to interference occasions such as power supply cross-line road; The thickened metalized polypropylene film capacitor in edge of alternating current-direct current occasions such as the demagnetization arc extinguishing of the startup of unidirectional asynchronous motor, thyristor, relay; Capacitor installing hole spacing 7.5mm on the circuit board can be used for, the requirement of film capacitor development trend can be satisfied.
