Description
Technical field
The utility model relates to field of capacitor manufacture, particularly a kind of modified model shell type capacitor.
Background technology
Capacitor is a kind of element can storing electric charge, is also one of the most frequently used electronic component.In DC circuit, capacitor is equivalent to open circuit.The simplest capacitor is made up of the pole plate at two ends and middle insulation dielectric (comprising air).After energising, pole plate is charged, coating-forming voltage (electrical potential difference), but due to the megohmite insulant of centre, so whole capacitor is nonconducting.But, such situation is under the precondition of the critical voltage not exceeding capacitor (puncture voltage).We know, any material is all opposing insulation, and the voltage when material two ends is increased to a certain degree, and material can conduct electricity, and we claim this voltage puncture voltage.Electric capacity is no exception, after electric capacity is breakdown, has been not just insulator.But at middle school period, such voltage be can not see in circuit, so all work below puncture voltage, can be seen by as insulator.
Along with making rapid progress of electronic information technology, the update speed goes of digital electronic goods is fast, based on the consumer electronics product volume of production and marketing sustainable growth of the products such as panel TV (LCD and PDP), notebook computer, digital camera, capacitor industry has been driven to increase.And having driven the development of associated materials, equipment Industry, China has become global capacitor big producing country.
And at present, film capacitor in commercially using can only be used for some little circuit, and waterproof and dampproof performance is not high, and under higher operating mode is needed for some security performances, can overlap again outward at capacitor and load onto a housing, and water last layer epoxy resin to improve its fire resistance.
And find when capacitor being loaded housing, because the specification of capacitor is many, its size is inconsistent, when loading housing, if the capacitor of often kind of specification is all equipped with the housing of a model, not only make trouble, and cost is higher, and if use the housing of same model, for the capacitor that some sizes are little, it is easily subjected to displacement after fitting into housing in housing, and impact uses normally.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of modified model shell type capacitor, can be good at well assembling between capacitor main body and housing and locating.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of modified model shell type capacitor, and its innovative point is: the housing comprising capacitor main body and the embedding of accommodation capacitor main body;
Described capacitor main body comprises a capacitor body, described capacitor body be by intermediate layer be dielectric, two-layer be up and down the cylinder of the inclined parallel shape of the winding film that the coat of metal is formed, be equipped with red brass metal derby at the two ends of capacitor body, two red brass metal derbies are welded with a pair symmetrically arranged L shape electrode respectively;
Described housing is the hollow cuboid of a flat, has the opening that an appearance capacitor main body embeds, the inwall of housing is provided with and carries out spacing position-limit mechanism to electrode in one end of housing.
Further, described position-limit mechanism comprises a pair symmetrically arranged spacing preiection, and described spacing preiection extends from the bottom of housing to opening direction, and between two spacing preiections, leave the space holding electrode and insert.
Further, described position-limit mechanism one has two, is symmetrically distributed on the madial wall of housing long axis direction both sides.
The utility model has the advantage of: in the utility model, by the setting of position-limit mechanism, when capacitor main body is carried out fitting in housing, position-limit mechanism is utilized to carry out spacing to the electrode of capacitor main body, ensure its installation site, after installation is complete, can also carry out spacing to electrode simultaneously, avoid capacitor main body to be subjected to displacement, affect follow-up use.
By the setting of two groups of position-limit mechanisms, better can guarantee that capacitor main body fits into after in housing can well be located, and avoids capacitor main body to offset in housing, affects follow-up use.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of capacitor main body in modified model shell type capacitor of the present utility model.
Fig. 2 is the schematic diagram of modified model shell type capacitor middle shell of the present utility model.
Embodiment
Schematic diagram is as shown in Figure 1 and Figure 2 known, and modified model shell type capacitor of the present utility model comprises capacitor main body and holds the housing 3 of capacitor main body embedding.
Capacitor main body comprises a capacitor body 1, capacitor body 1 be by intermediate layer be dielectric, two-layer be up and down the cylinder of the inclined parallel shape of the winding film that the coat of metal is formed, be equipped with red brass metal derby at the two ends of capacitor body 1, two red brass metal derbies are welded with a pair symmetrically arranged L shape electrode 2 respectively.
Housing 3 is the hollow cuboid of a flat, has the opening that an appearance capacitor main body embeds, the inwall of housing 3 is provided with and carries out spacing position-limit mechanism to electrode in one end of housing 3.
Position-limit mechanism comprises a pair symmetrically arranged spacing preiection 4, and spacing preiection 4 extends from the bottom of housing 3 to opening direction, and between two spacing preiections 4, leave the space holding electrode 2 and insert.
Position-limit mechanism one has two, is symmetrically distributed on the madial wall of housing long axis direction both sides.
Operation principle: when assembling capacitor, the motor 2 at capacitor main body 1 two ends is aimed at respectively the space formed between two spacing preiections 4, and insert in housing 3, thus the assembling achieved between capacitor main body and housing, in addition, after assembling completes, two spacing preiections, 4 pairs of electrodes are utilized to carry out spacing, avoid it to be subjected to displacement, thus ensure that capacitor integral position is not subjected to displacement.
