Abstract
The utility model belongs to the technical field of lighting equipment accessories, in particular to a polyester film capacitor used for an electronic energy-saving lamp. With the polyester film capacitor adopted, technical problems such as unreasonable design and short service life in the prior art can be solved. The polyester film capacitor used for the electronic energy-saving lamp is characterized in that the capacitor comprises a flat winding portion; one side of the winding portion is provided with two correspondingly-arranged extending portions, wherein the extending portions and the winding portion are connected together so as to form one entity, one extending portion is provided with a positive-pole wire lead pin, and the other extending portion is provided with a negative-pole wire lead pin; the positive-pole wire lead pin and the negative-pole wire lead pin are parallel to each other and are separated by 4mm +/- 1mm; and the capacitor further comprises a protection layer which is encapsulated on the exteriors of the winding portion and the extending portions. Compared with the prior art, the polyester film capacitor used for the electronic energy-saving lamp of the utility model has the advantages of more reasonable design, simpler structure, little possibility of being fractured of the wire lead pins, reduced use cost, low manufacturing cost and long service life.
Description
Technical field
The utility model belongs to lighting apparatus accessory technical field, especially relates to a kind of polyester film condenser for electronic energy-saving lamp.
Background technology
Along with making rapid progress of electronic information technology, the update speed of digital electronic goods is more and more faster, take products such as panel TV, notebook computer, digital cameras as 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 prolong the useful life of capacitor, for this reason, people have carried out long-term exploration, have proposed various solutions.
For example, Chinese patent literature discloses a kind of capacitor [application number: 03264728.X], consisted of by shell, fuse, binding post and grounding screw, described fuse is arranged on enclosure, described grounding screw is arranged on the bottom end face of shell, described binding post is arranged at the top end face of shell, also is provided with some projections on the bottom end face of described shell.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 the two schemes here still exists wiring to fracture easily, and useful life is short, and in addition, cost is higher.
The utility model content
The purpose of this utility model is for the problems referred to above, and the polyester film condenser that is used for electronic energy-saving lamp of the low and long service life of a kind of cost is provided.
For achieving the above object; the utility model has adopted following technical proposal: this is used for the polyester film condenser of electronic energy-saving lamp; it is characterized in that; this capacitor comprises the winder that is flat; have two corresponding extensions that arrange and be connected as a single entity with winder in a side of winder; an extension therein is provided with the positive wire pin; be provided with the negative wire pin at another extension; described positive wire pin and negative wire pin be parallel to each other and between spacing be 4mm ± 1mm, this capacitor also comprises the protective layer that is encapsulated in respectively winder and extension outside.
At the above-mentioned polyester film condenser that is used for electronic energy-saving lamp, described protective layer is made by epoxy resin.
At the above-mentioned polyester film condenser that is used for electronic energy-saving lamp, described positive wire pin and negative wire pin are fixed on the extension by electric welding respectively.
Compared with prior art, this advantage that is used for the polyester film condenser of electronic energy-saving lamp is: it is more reasonable to design, and structure is simpler, terminal pin is frangibility not, has virtually reduced use cost, in addition, its low cost of manufacture, long service life meets the trend of current social technical development.
Description of drawings
Fig. 1 is the structural representation that the utility model provides.
Fig. 2 is the side-looking structural representation that the utility model provides.
Among the figure, winder 1, extension 2, positive wire pin 21, negative wire pin 22, protective layer 3.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Shown in Fig. 1-2; this polyester film condenser that is used for electronic energy-saving lamp comprises the winder 1 that is flat; have two corresponding extensions 2 that arrange and be connected as a single entity with winder 1 in a side of winder 1; an extension 2 therein is provided with positive wire pin 21; be provided with negative wire pin 22 at another extension 2; described positive wire pin 21 and negative wire pin 22 be parallel to each other and between spacing be 4mm ± 1mm, this capacitor also comprises the protective layer 3 that is encapsulated in respectively winder 1 and extension 2 outsides.Obviously, present embodiment design is more reasonable, and structure is simpler, and terminal pin is frangibility not, has virtually reduced use cost, in addition, its low cost of manufacture, long service life meets the trend of current social technical development.
Specifically, the protective layer 3 of present embodiment is made by epoxy resin.In addition, as a kind of prioritization scheme, here positive wire pin 21 and negative wire pin 22 are fixed on the extension 2 by electric welding respectively.
As the scheme of optimizing the most of present embodiment, the spacing between positive wire pin 21 and the negative wire pin 22 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 the terms such as winder 1, extension 2, positive wire pin 21, negative wire pin 22, protective layer 3, 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.
