Abstract
The invention discloses a safe capacitor. The safe capacitor comprises a shell; a locating sleeve and a core are arranged in the shell, the core is connected with a pin located outside the shell, and the locating sleeve is used for locating the core and locating a connection wire of the pin; meanwhile, the shell is filled with a filler; moreover, the core and the locating sleeve are prepared from a PP material, the shell is an aluminum shell, and the core is externally provided with a PET external coating film. The safe capacitor has the advantage of relatively steady structure. The invention also discloses a preparation method of the safe capacitor.
Description
Technical field
The present invention relates to electronic component technology field, especially relate to a kind of safety type capacitor.The invention still further relates to the preparation method of this safety type capacitor.
Background technology
Capacitor, English name: Capacitor is one of a large amount of electronic component used in electronic equipment, be widely used in circuit every aspects such as straight-through friendship, coupling, bypass, filtering, resonant tank, power conversion, controls.A kind of capacitor wherein comprises housing, is provided with fuse in housing, and the pin of fuse is positioned at the outside of housing, and has the inserts such as oil in housing.Such capacitor to a certain extent, uses more for convenience.But, there is the defect that structure is stable not and fail safe is poor.
Summary of the invention
For the deficiency that above-mentioned prior art exists, the object of this invention is to provide a kind of safety type capacitor, it has structure and comparatively stablizes, uses safer feature.The invention also discloses the preparation method of this safety type capacitor.
To achieve these goals, the technical solution adopted in the present invention is: safety type capacitor, comprises housing, is provided with positioning sleeve and fuse in this housing, this fuse is connected with the pin being positioned at this outside, this positioning sleeve, for locating the connecting line of this fuse and positioning pins, meanwhile, is filled with inserts in this housing, and, this fuse and positioning sleeve adopt the preparation of PP material, and this housing adopts aluminium shell, and described outside core is provided with PET peplos.
Described inserts is dry insulating air or six-component force balance gas.
The preparation method of previous security type capacitor, include conventional housing preparation, prepare fuse, peplos is set for fuse, load positioning sleeve and fuse, seal casinghousing, insert the step of inserts, the described mode arranging peplos for fuse is: first at the one side precoating PUR of PET peplos, then this PET peplos is wound around 8 ~ 20 circles at outside core, afterwards, toast under the constant temperature of any one temperature spot in 100 ~ 110 DEG C, until peplos is wrapped in the outside of fuse closely.
The present invention is compared to the prior art advantageously: structure is comparatively stablized, it is safer to use.The fuse of safety type capacitor of the present invention is same as the preparation of prior art many employings PP material, and the peplos of outside core adopts PET material preparation, due to PP material there is negative temperature characteristic, PET material has positive temperature characterisitic, thus the structure of this capacitor tended towards stability.Meanwhile, inserts adopts dry air or six-component force balance gas, not only reduces the weight of product, reduces product cost, and inserts is nontoxic, can not burn, and adds fail safe when capacitor uses.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the front sectional view of the safety type capacitor of embodiments of the invention.
In figure:
10, housing;
20, fuse;
30, pin;
40, inserts;
50, positioning sleeve.
Embodiment
Embodiment, as shown in Figure 1: safety type capacitor, comprises housing 10, is provided with positioning sleeve 50 and fuse 20 in this housing 10, and this fuse 20 is connected with the pin 30 being positioned at this housing 10 outside.This positioning sleeve 50 is for locating the connecting line of this fuse 20 and positioning pins 30.Meanwhile, inserts 40 is filled with in this housing 10.And this fuse 20 and positioning sleeve 50 adopt PP material to prepare, this housing 10 adopts aluminium shell.
Further say, this fuse 20 outside is provided with PET peplos.Like this, due to PP material there is negative temperature characteristic, PET material has positive temperature characterisitic, thus the structure of this capacitor tended towards stability.
Further say, this inserts 40 is dry insulating air or six-component force balance gas.Wherein, especially six-component force balance gas not only nontoxic, do not burn, have more excellent insulation and arc extinction performance, improve the fail safe of product.
The preparation method of previous security type capacitor, includes conventional housing preparation, prepares fuse, arranges peplos for fuse, loads positioning sleeve and fuse, seal casinghousing, inserts the step of inserts.Difference is, the mode arranging peplos for fuse is: first at the one side precoating PUR of PET peplos, then this PET peplos is wound around 8 ~ 20 circles at outside core.Such as, 8 circles, 12 circles or 20 circles are wound around.Certainly, there is the one side of PUR inwardly.Afterwards, toast under the constant temperature of any one temperature spot in 100 ~ 110 DEG C, until peplos is wrapped in the outside of fuse closely.Bake process can carry out in constant temperature roaster, and set temperature can be 100 DEG C, 105 DEG C or 110 DEG C.Like this, these peploses define the surrounding layer of fuse, are conducive to the stability improving capacitor.
The foregoing is only the preferred embodiments of the present invention; not thereby the scope of the claims of the present invention is limited; every utilize specification of the present invention and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
