Description
Technical field
The utility model relates to fuse technologies field, is specially a kind of melt of Intelligent fuse band current-limiting function.
Background technology
Any fuse especially Intelligent fuse all the protected electric equipment of demand fulfillment propose time, current characteristics; and the requirement that all kinds of fuses produced now have part-time, current characteristics does not reach protected electric equipment; that is protective value can not meet the demands; for this reason, we propose a kind of melt of Intelligent fuse band current-limiting function.
Summary of the invention
The purpose of this utility model is the melt providing a kind of Intelligent fuse band current-limiting function, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of melt of Intelligent fuse band current-limiting function, comprise melt mainboard, quick link, draw-in groove, louvre, melt groove, solder bath and metal coating, two sides of the front and back of described melt mainboard are symmetrically distributed with 12 draw-in grooves, draw-in groove is fixed on insulating base, the left and right sides of melt mainboard be all provided with quick link, the centre position of the panel of described melt mainboard is provided with solder bath, described solder bath is connected with six the melt grooves being symmetrically distributed in melt mainboard both sides by splitter box, scolding tin is provided with in solder bath, the both sides of described melt groove all symmetrical the louvre arranged of three row two, the left side head of described melt mainboard and right side head are all provided with metal coating.
Preferably, described quick hanging head also can be groove and hook.
Preferably, described solder bath is the kidney-shaped groove of a 0.1cm more shallow than the thickness of melt mainboard.
Preferably, described metal coating thickness is no more than 0.3mm.
Compared with prior art, the beneficial effects of the utility model are: the melt of this Intelligent fuse band current-limiting function, the solder bath adopted, when short circuit, scolding tin in solder bath groove dissolves at first, then melt groove is flowed into, good metallurgical effect can be produced, melt is at melt groove quick fuse, substantially increase the sensitivity of fusing, the metal backing of one or more layers of different materials is laid with at the two ends of melt mainboard, its resistivity is different, when electric current is by melt, the distribution of different electric current is produced between them, the feature utilizing this electric current to distribute can change different heat condition and radiating condition, effectively can control the temperature rise of bath surface, because section ratio is small in ends, and power consumption is large, and it is positioned at again the centre of whole melt, large and the weak heat-dissipating of caloric value, when there is overload current, middle just easily fusing, thus the time of adjustable fuse, current characteristics.
Accompanying drawing explanation
Fig. 1 is vertical view of the present utility model;
Fig. 2 is front view of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technical scheme: a kind of melt of Intelligent fuse band current-limiting function, comprise melt mainboard 1, quick link 2, draw-in groove 3, louvre 4, melt groove 5, solder bath 6 and metal coating 7, two sides of the front and back of described melt mainboard 1 are symmetrically distributed with 12 draw-in grooves 3, draw-in groove 3 is fixed on insulating base for melt, the left and right sides of melt mainboard 1 be all provided with quick link 2, binding post for melt and fuse realizes Fast Installation, described quick hanging head 2 also can be other device for quickly disassembling such as groove and hook, the centre position of the panel of described melt mainboard 1 is provided with solder bath 6, described solder bath 6 is the kidney-shaped groove of a 0.1cm more shallow than the thickness of melt mainboard 1, and solder bath 6 is connected with six the melt grooves 5 being symmetrically distributed in melt mainboard 1 both sides by splitter box, scolding tin is provided with in solder bath 6, when short circuit, scolding tin in solder bath 6 groove dissolves at first, then melt groove 5 is flowed into, good metallurgical effect can be produced, melt is at melt groove 5 quick fuse, substantially increase the sensitivity of fusing, the both sides of described melt groove 5 all symmetrical three row two arrange louvre 4, the left side head of described melt mainboard 1 and right side head are all provided with metal coating 7, the effect of metal coating 7 mainly makes the melt mainboard 1 made can meet the proposed time, current characteristics, the concrete cross-sectional sizes of metal material determines according to the rated current of design, general single melt is in the scope of 5A-15A, metal coating 7 thickness is no more than 0.3mm, the method of coating can be compacting, brush plating or plating.Due to the metal coating 7 at the two ends of melt mainboard 1 of the present utility model, its resistivity is different, when electric current passes through the middle part non-matel coated coating 7 of melt mainboard 1, the distribution of different electric current is created between the middle part of melt mainboard 1 and both ends, be provided with layer of metal coating 7, the resistivity of internal layer melt mainboard 1 is greater than the resistivity of metal coating 7, then being distributed by electric current is obviously the electric current that the electric current of melt mainboard 1 is less than metal coating 7, otherwise, then the electric current of melt mainboard 1 is greater than the electric current of metal coating 7, utilize this distribution feature, different heat condition and radiating condition can be changed, effectively can control the temperature rise of bath surface, and the section ratio two ends of melt mainboard 1 mid portion are much smaller, and power consumption is much bigger, be positioned at again the middle part of whole melt, large and the weak heat-dissipating of caloric value, when there is overload current, middle part is easily fusing just, thus the time of adjustable fuse, current characteristics, utilize this principle can reach the different time required, current characteristics.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to execution mode, but not each execution mode only comprises an independently technical scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technical scheme in each embodiment also through appropriately combined, can form other execution modes that it will be appreciated by those skilled in the art that.
