Abstract
The utility model discloses a kind of two melts of Intelligent fuse, together with described upper melt is symmetrically welded with lower melt, described upper melt and lower melt just facing to all upwards, two sides of the front and back of described melt mainboard are symmetrically distributed with 12 draw-in grooves, the overlap of the left and right sides of melt mainboard is all provided with quick hanging head, the centre position of the panel of described melt mainboard is provided with solder bath, and solder bath is connected with six the melt grooves being symmetrically distributed in melt mainboard both sides by splitter box, is provided with scolding tin in solder bath.Two melts of this Intelligent fuse, the two melt structures adopted can meet normal requirement of withstand voltage, again can not because of the too thick phenomenon causing improper fusing of melt, when short circuit, scolding tin in solder bath groove dissolves at first, then flows into melt groove, can produce good metallurgical effect, melt, at melt groove quick fuse, substantially increases the sensitivity of fusing.
Description
Technical field
The utility model relates to fuse technologies field, is specially a kind of two melts of Intelligent fuse.
Background technology
Fuse is simply a kind of and effective protective device.Mainly play short-circuit protection effect in circuit.Primarily of melt and insulated tube (insulating base) composition installing melt.The shape of melt is divided into thread and banded two kinds, and banded melt will offer some through holes usually from the teeth outwards, and these through holes play heat radiation and produce the effect of fracture muscle.The shape of these through holes is circular or some irregular shapes substantially, the gap of this some holes is as fracture muscle during short circuit fault, need according to electric current and voltage grade through accurate Calculation, the thickness of melt also will strictly control simultaneously, the too thick or too thin result of use that all can affect fuse, too thin do not reach dangerous fusing value will by improper fusing, too thick spontaneous heat production will be very large, also easily there is improper fusing, the situation of the latter is particularly evident in the circuit of high pressure high load capacity, for this reason, we propose a kind of two melts of Intelligent fuse.
Summary of the invention
The purpose of this utility model is the two melts providing a kind of Intelligent fuse, 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 two melts of Intelligent fuse, comprise melt and lower melt, together with described upper melt is symmetrically welded with lower melt, described upper melt and lower melt just facing to all upwards, upper melt and lower melt all comprise melt mainboard, quick hanging head, draw-in groove, louvre, melt groove and solder bath, two sides of the front and back of described melt mainboard are symmetrically distributed with 12 draw-in grooves, the overlap of the left and right sides of melt mainboard is all provided with quick hanging head, the centre position of the panel of described melt mainboard is provided with solder bath, and 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.
Preferably, described upper melt and lower melt are all the groove structure of band left and right sides band overlap.
Preferably, the distance between the groove formed between described upper melt and lower melt is at 0.5-1cm, and best at 0.6cm.
Preferably, described solder bath is the rectangular recess of a 0.2cm more shallow than the thickness of melt mainboard.
Preferably, described quick hanging head can be other device for quickly disassembling such as groove, link or hook.
Compared with prior art, the beneficial effects of the utility model are: two melts of this Intelligent fuse, the two melt structures adopted can meet normal requirement of withstand voltage, again can not because of the too thick phenomenon causing improper fusing of melt, when short circuit, scolding tin in solder bath groove dissolves at first, then flows into melt groove, can produce good metallurgical effect, melt, at melt groove quick fuse, substantially increases the sensitivity of fusing.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model.
In figure: melt, 2 times melts, 11 melt mainboards, 12 quick hanging heads, 13 draw-in grooves, 14 louvres, 15 melt grooves and 16 solder baths on 1.
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 two melts of Intelligent fuse, comprise melt 1 and lower melt 2, together with described upper melt 1 is symmetrically welded with lower melt 2, described upper melt 1 and lower melt 2 are all the groove structure of band left and right sides band overlap, described upper melt 1 and lower melt 2 just facing to all upwards (face of overlooking in Fig. 2 is front), two melt structures like this can meet normal requirement of withstand voltage, again can not because of the too thick phenomenon causing improper fusing of melt, distance between the groove formed between described upper melt 1 and lower melt 2 is at 0.5-1cm, and it is best at 0.6cm.
Upper melt 1 and lower melt 2 all comprise melt mainboard 11, quick hanging head 12, draw-in groove 13, louvre 14, melt groove 15 and solder bath 16, two sides of the front and back of described melt mainboard 11 are symmetrically distributed with 12 draw-in grooves 13, draw-in groove 13 is fixed on insulating base for melt, the overlap of the left and right sides of melt mainboard 11 is all provided with quick hanging head 12, binding post for melt and fuse realizes Fast Installation, described quick hanging head 12 can be groove, other device for quickly disassembling such as link or hook, the centre position of the panel of described melt mainboard 11 is provided with solder bath 16, described solder bath 16 is the rectangular recess of a 0.2cm more shallow than the thickness of melt mainboard 11, and solder bath 16 is connected with six the melt grooves 15 being symmetrically distributed in melt mainboard 11 both sides by splitter box, scolding tin is provided with in solder bath 16, when short circuit, scolding tin in solder bath 16 groove dissolves at first, then melt groove 15 is flowed into, good metallurgical effect can be produced, melt is at melt groove 15 quick fuse, substantially increase the sensitivity of fusing, the both sides of described melt groove 15 all symmetrical the louvre 14 arranged of three row two.
