Abstract
The utility model belongs to the technical field of capacitors, particularly relates to a composite film capacitor. With the composite film capacitor adopted, technical problems such as unreasonable design and poor dissolution-resisting performance can be solved. The composite film capacitor includes a winding body; the winding body is provided with two radial lead-out lines which are arranged correspondingly and are parallel to each other. The composite film capacitor is characterized in that the distance between the two radial lead-out lines is from 4mm+/-1.2mm; the winding body is provided with a flame retardant encapsulation layer coated on the exterior of the winding body; the thickness of the flame retardant encapsulation layer is 1.3mm; and the winding body is flat, and the thickness of the winding body is from 4.5 mm+/-0.6mm. Compared with the prior art, the composite film capacitor of the utility model has the advantages of more reasonable design, simple structure, easiness in installation and disassembly, strong practicability and excellent moisture resistance and dissolution resistance, and accords with current social development trends.
Description
Technical field
The utility model belongs to the capacitor technology field, especially relates to a kind of bifilm capacitor.
Background technology
Bifilm capacitor is mainly used in all kinds of complete machines, along with making rapid progress of electronic information technology, the update speed of digital electronic goods is more and more faster, with panel TV, notebook computer, the products such as digital camera are main consumer electronics product volume of production and marketing sustainable growth, driven the capacitor industrial growth, the storage electric charge that the electrode that conductor approaching by two and mutually insulated is made forms and the device capacitor of electric energy are one of a large amount of electronic components that use in the electronic equipment, be widely used in handing over every straight-through in the circuit, coupling, bypass, filtering, resonant tank, power conversion, the aspects such as control.In order to improve the safety in utilization of bifilm capacitor, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of metallic film capacitor [application number: CN02225590.7], it is by terminal, end seat sealing ring, loam cake, explosion-proof line connects wire, the loam cake sealing ring, on mould cover, plug, capacitance core, shell, under mould cover and form, in the shell upper of capacitor the groove of one infolding is arranged, a terminal directly is connected with capacitance core with explosion-proof line, another terminal directly is connected with the capacitor core other end by electric capacity plug centre bore with connecting wire, is provided with a groove between the groove of the shell upper infolding of capacitor and capacitor case top.In addition, Chinese patent literature also discloses another kind of capacitor [application number: 201020698211.4], include body, sleeve, end cap and binding post, one end of sleeve is socketed on the body, the other end of sleeve connects end cap, binding post links to each other with body and stretches out in outside the end cap, it is characterized in that: the spinosity sheet also is set between described body and the sleeve, the thorn sheet includes inserted sheet and the plug that is connected on this inserted sheet, be provided with flexure strip on the plug, one end of flexure strip is connected on this plug, and the other end of flexure strip sticks up to turning up towards the inserted sheet lateral direction, and the inner chamber of sleeve is provided with the socket that can match with plug; The both sides of inserted sheet respectively interval are provided with a plurality of hangnails, and above-mentioned two schemes has improved prior art to a certain extent, but its complex structure of capacitor here, are difficult for installing and the shortcoming such as anti-dissolubility is poor but also exist, and can't satisfy instructions for use.
The utility model content
The purpose of this utility model is for the problems referred to above, provides a kind of simple in structure, is easy to install the bifilm capacitor good with anti-dissolubility.
For achieving the above object, the utility model has adopted following technical proposal: this bifilm capacitor comprises the coiling body, be provided with two corresponding radially lead-out wires that arrange and be parallel to each other at the coiling body, it is characterized in that, the described radially spacing between the lead-out wire is 4mm ± 1.2mm, described coiling body is provided with the fire-retardant encapsulated layer that is covered in this coiling body exterior, and described fire-retardant encapsulated layer thickness is 1.3mm, and described coiling body is flat and thickness is 4.5mm ± 0.6mm.Obviously, it is more reasonable to the utlity model has design, and structure is simpler, easily installation and removal, and practical, in addition, its moisture-proof and anti-dissolubility are all very good, meet the trend of current social technical development.
As preferably, in above-mentioned bifilm capacitor, described fire-retardant encapsulated layer is fire retarding epoxide resin.
As preferably, in above-mentioned bifilm capacitor, described coiling body thickness is 4.6mm.
Compared with prior art, the advantage of this bifilm capacitor is: it is more reasonable to design, and structure is simpler, easily installation and removal, and practical, in addition, its moisture-proof and anti-dissolubility are all very good, meet the trend of current social technical development.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Fig. 2 is another visual angle structural representation that the utility model provides.
Among the figure, coiling body 1, radially lead-out wire 2, fire-retardant encapsulated layer 3.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, this bifilm capacitor comprises coiling body 1, be provided with two corresponding radially lead-out wires 2 that arrange and be parallel to each other at coiling body 1, prioritization scheme, spacing between the radially lead-out wire 2 here is 4mm ± 1.2mm, described coiling body 1 is provided with the fire-retardant encapsulated layer 3 that is covered in this coiling body 1 outside, and described fire-retardant encapsulated layer 3 thickness are 1.3mm, and described coiling body 1 is flat and thickness is 4.5mm ± 0.6mm.Obviously, the present embodiment design is more reasonable, and structure is simpler, easily installation and removal, and practical, in addition, its moisture-proof and anti-dissolubility are all very good, meet the trend of current social technical development.
Specifically, the fire-retardant encapsulated layer 3 of present embodiment is fire retarding epoxide resin.As the optimized scheme of present embodiment, coiling body 1 thickness here is 4.6mm, and radially the spacing between the lead-out wire 2 is 4mm.
Specific embodiment described herein only is to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has more used coiling body 1, the term such as lead-out wire 2, fire-retardant encapsulated layer 3 radially, do not get rid of the possibility of using other term.Using these terms only is in order to describe more easily and explain essence of the present utility model; They are construed to any additional restriction all is contrary with the utility model spirit.
