The current fuse comprises an insulating box body with a cavity, a first electric conductor, a second electric conductor and a conductive spring plate; the inner ends of the first electric conductor and the second electric conductor are positioned inside the cavity; the outer ends of the first electric conductor and the second electric conductor extend out of the insulating box body; a gap is arranged between the inner ends of the first electric conductor and the second electric conductor; a first end of the conductive spring plate is fixed; a second end of the conductive spring plate is pre-pressed, extends to the gap, and is integrally welded with the inner ends of the first electric conductor and the second electric conductor; accordingly, when short circuit happens, a large amount of heat is produced instantly at the positions of welding spots and can not timely dissipate, and the heat capacity of the positions of thewelding spots is extremely small, thereby the welding spots are enabled to fuse in a very short period; the conductive spring plate overcomes the surface tension of welding spot materials and externalresistance and then bounces off, thereby the current fuse has extremely high switch-off reliability.
Description
Technical field
The utility model relates to the power battery technology field, more particularly, and the electrokinetic cell that relates to a kind of current fuse and have this current fuse.
Background technology
Day by day exhausted in non-renewable resources such as oil, under the serious all the more background of environmental pollution, people express very big expectation to new-energy automobile.Electrokinetic cell then is the heart of new-energy automobile, and it is storing huge electric energy.Because the mobility that has of automobile and the uncertainty of outdoor road conditions guarantee that the safety of electrokinetic cell becomes problem demanding prompt solution, especially to the short-circuit protection of electrokinetic cell.
Please refer to Fig. 1, in order to realize short-circuit protection to electrokinetic cell, the way of prior art be the soldering connected mode at cell 2 ' adopt lug butt joint, overlap joint be provided with fusing structure (fuse) 1 '.When cell 2 ' when being short-circuited, electric current be about to fuse structure 1 ' the solder joint fusing, the melt after the fusing comes off under the effect of gravity, thereby realizes the short circuit to electrokinetic cell.The defective of this way is:
The reliability that the fusing structure disconnected when one, short circuit took place is not enough
Weld after the fusing structure 1 ' design, cell 2 ' be assembled into power brick with cell 2 ' employing integral type.Like this, cell 2 ' between inevitably can have stress.The high temperature that electric current produces during short circuit can make be connected and fixed cell 2 ' backing plate softening; cell 2 ' the position can stress release and be moved; may make the fusing structure 1 that this has disconnected ' overlap again, thereby lose the effect of short-circuit protection.And actual application also shows, the fusing structure 1 of employing butt joint and overlapping mode setting ' because weld seam is little and stress release causes moving of cell 2 ' position, make in most cases, though fusing structure 1 ' the solder joint fusing but still can not effectively disconnect.
Two, arcing phenomenon
Cell 2 ' all fusing structures all can not be avoided the arcing phenomenon effectively.Even do not consider moving of monomer battery location under the welding stress effect, because the distance of fusing structure 1 ' weld seam is very little, fusing structure 1 ' when reality disconnected, the voltage at the structure that fuses 1 ' two ends was very big, can produce very strong arcing.Because the battery inclusion under normal circumstances just may produce some fuel gas; the amount that produces fuel gas in the time of short circuit is bigger; if do not carry out the arc extinguishing protection effectively; the high temperature that arcing produces is enough to ignited flammable gas; cause potential safety hazard, even may be because the arcing that continues make the structure 1 that fuses ' the lose effect of short-circuit protection.
Three, the short-circuit protection response time is oversize
In the prior art, the fusing structure 1 of docking mode setting ' in 1000A short circuit current following opening time is 40-50s.And the minimum unit of fusing structural defence is 2 monomers between cell, and the electric current of 2 cell short circuits only has the time dimension of 10-15s to be held between the 1000-1300A.Therefore, for this electrokinetic cell that is made of 2 cells, the response speed of short-circuit protection is nowhere near.
Four, manufacturing and later maintenance trouble
In the power brick manufacture process, because fusing structure and cell are integrated designs, the welding of fusing structure must be carried out after the assembling of battery inclusion is finished, because the inclusion volume and weight is very big, will inevitably influence the consistency of welding efficiency, welding quality and welding.In addition, in the power brick later maintenance, if short circuit or other reason cause between monomer the fusing structure fusing to occur or produce can not the damage of reparation property, the repair meeting of integral structure battery is very loaded down with trivial details, in the time must changing the fusing structure, usually need to change the entire cell monomer, rehabilitation cost will be very high and pretty troublesome.

Please refer to Fig. 2 and Fig. 3, preferred embodiment for the utility model current fuse, this current fuse comprises the insulation box body 1 and first with cavity, second electric conductor 2,3, first, second electric conductor 2,3 the inners are positioned at described cavity, described insulation box body 1 is extended in the outer end, described first, second electric conductor 2, has slit 4 between the inner of 3, this current fuse also comprises an electroconductive elastic sheet 5, first end of described electroconductive elastic sheet 5 is fixed, and its second end is extended to described slit 4 by precompressed and with described first, second electric conductor 2, the inner of 3 welds together.Like this; because first end of described electroconductive elastic sheet 5 is fixed; its second end is extended to described slit 4 and welds together with the inner of described first, second electric conductor 2,3 by precompressed; when short circuit takes place; because electric current is very big; moment produces a large amount of heat at the solder joint position and has little time to distribute; and the thermal capacitance at solder joint position is very little; therefore can make the solder joint fusing in very short time; electroconductive elastic sheet 5 promptly overcomes the surface tension of welding material and external drag and flicks; thereby realize protection, have very high disconnection reliability battery.
Below above-mentioned each part is described in detail respectively.
Please in conjunction with reference Fig. 4 and Fig. 5, described insulation box body 1 comprises upper cartridge body 11 and lower box body 12, described cavity is surrounded by described upper and lower box body 11,12 and forms, and is become upper and lower two seal chambers 13,14 at interval by described first, second electric conductor 2,3 that welds together and electroconductive elastic sheet 5.Upper and lower box body 11,12 is made by material high temperature resistant, corrosion resistance.Because current fuse adopts the stand alone type design, when being short-circuited, under the situation of backing plate (in order to be connected and fixed the member of battery cell) because of hot mastication, the rigidity of insulation box body 1 is enough to overcome owing to moving because of Installation Stress discharges the position that produces between cell 7 (please refer to Fig. 7), has overcome the defective that the fusing structure can not effectively disconnect in the prior art.In the present embodiment, described upper and lower box body 11,12 is respectively equipped with first, second groove 111,121 so that the inner space of described upper and lower seal chamber 13,14 to be provided respectively.Described first, second electric conductor 2,3 that welds together and electroconductive elastic sheet 5 between described first, second groove 111,121 to realize the sealing of described upper and lower seal chamber 13,14.Described electroconductive elastic sheet 5 is positioned at described second groove, 121 1 sides, and its width is narrower than described second groove 121.Electroconductive elastic sheet 5 can effectively not eject and interfere with lower seal cavity 14 when short circuit is taken place, and the height of lower seal cavity 14 is greater than the described height of going up seal chamber 13.The correspondence position of described upper cartridge body 11, electroconductive elastic sheet 5, first, second electric conductor 2,3, lower box body 12 is provided with a plurality of screws, and by screw 6 fastening (please refer to Fig. 3).First end of electroconductive elastic sheet 5 (being the long limit 52 of aftermentioned) is clamped between first electric conductor 2 and the lower box body 12 to realize the location.
In order to realize the arc extinguishing function, on described, be filled with arc-extinguishing medium quartz sand in the seal chamber 13, like this, when solder joint fusing and electroconductive elastic sheet 5 flick slit 4, quartz sand promptly under the effect of gravity can from seal chamber 13 4 flow into lower seal cavitys 14 through the slit, the influence that can effectively eliminate arcing and caused is eliminated arcing high temperature hidden danger when disconnecting stability strengthening.Certainly, described arc-extinguishing medium can also be for having the other materials of similar functions.In the present embodiment, the sidewall of described upper cartridge body 11 offer with described on the screw 112 that connects of seal chamber 13, described quartz sand promptly pours into via described screw 112, and after quartz sand poured into, described screw 112 can pass through screw (not shown) sealing and fixing.
Described electroconductive elastic sheet 5 is a spring steel plate, and spring steel plate has better elastic, but can not carry out soldering, and copper has solderability and corrosion resistance preferably, thus the spring steel plate that processes can be made copper plating treatment, to improve its weldability and corrosion resistance.Spring steel is used very extensive, and with respect to the melt material-copper and the silver of at present big current fuse main flow, its price is quite cheap, and has good elasticity and creep-resistant property, but electric conductivity is low.And present embodiment utilizes poor slightly conductivity of spring steel plate and better elastic just.In the present embodiment, the cross section of described electroconductive elastic sheet 5 is L-shaped, and the minor face 51 at its second end place is extended to described slit 4 and welds together with the inner of described first, second electric conductor 2,3 by precompressed.The long limit 52 at its first end place to the perk of the outside of electroconductive elastic sheet 5, like this, in the time of in minor face 51 is welded in slit 4, just stores on the long limit 52 and makes the elastic potential energy of electroconductive elastic sheet 5 to described lower seal cavity 14 directions motion under nature.When short circuit took place, when solder joint is melted, elastic potential energy promptly discharged, and makes minor face 51 thoroughly break away from slits 4, thereby realizes disconnecting reliably.Changed and relied on gravity that the melt residue is come off to realize the mode of short-circuit protection in the prior art merely.
In the present embodiment, described first, second electric conductor 2,3 all is tabular, and being conductive section is the T2 copper coin.Wherein portion is provided with respectively for screw 6 and wears fixing threaded hole 21,31, and its outer end is respectively equipped with the installing hole 22,32 that is connected with battery cell 7 for whole current fuse, and its inner is the trapezium structure that narrows down gradually.This structure of its inner can suitably increase the resistance between first, second electric conductor 2,3, and the temperature of solder joint is quickened the fusing of solder joint when improving the short circuit generation.
Present embodiment is when satisfying normal overcurrent and having certain overload capacity, and the energy quick fuse is reduced to minimum to the damage of battery unusually with short circuit when short circuit, convenient simultaneously the manufacturing and later maintenance.Because during operate as normal, the heat that the current fuse bond pad locations is distributed has time enough to pass to cell and heat management system by first, second electric conductor 2,3, and some heat is absorbed by arc quenching material quartz sand.The temperature basically identical of the local temperature of bond pad locations and first, second electric conductor 2,3, thus commissure local electrical resistance and first, second electric conductor 2,3 can be considered as one, and overall electrical resistance is little, therefore has stronger conveyance capacity.And electric current is very big during short circuit, and the speed that the solder joint amount of localized heat increases is enhanced about 10 times.Most of heat has little time to distribute, and the local quality of solder joint is very little with respect to first, second electric conductor 2,3 and quartz sand, so hot melt is also very little, thereby makes the temperature of commissure raise rapidly and reaches fusing point, solder joint fusing, electroconductive elastic sheet 5 are promptly rebounded and are gone up seal chamber 13.
Describe below in conjunction with experiment, first, second electric conductor 2,3 of experiment exemplar is of a size of the T2 copper coin of 1.7*40mm and 2*40mm for conductive section, weld seam (being slit 4) distance is 1.5mm, and the conductive section of electroconductive elastic sheet 5 is of a size of 15*1.7mm, thick 0.4mm.The overall electrical resistance of current fuse is the 0.1-0.13 milliohm, weld seam local electrical resistance 0.04-0.05 milliohm.Under the situation of 350A overload, current fuse can guarantee 15 minutes overload at least; Under the 1000A short-circuit conditions, the time of current fuse fusing only is 18-20s.On the other hand; the minimum battery unit that current fuse is protected has two cells; and test records when two cell short circuits, and the average current of preceding 20s is 1023A, so the response time of present embodiment can be satisfied the requirement of two cell short-circuit protections.
In addition, the fusing structure between cell should have conductivity preferably, has the good short-circuit protection response time again.Because the overall electrical resistance of current fuse is more little, overload capacity is strong more; The weld seam local electrical resistance is big more, and the short-circuit protection response time is short more.Present embodiment can be easily by increasing the weld seam local electrical resistance, reducing the response time that the local quality of weld seam shortens short-circuit protection.The structure by adjusting first, second electric conductor 2,3 and the thickness of electroconductive elastic sheet 5 can effectively be adjusted the local electrical resistance of weld seam and the overall electrical resistance and the thermal capacitance of current fuse, make it can satisfy different requirements.Because when the fusing structural material was determined, it was contradiction that the shortening of fusing time and overall electrical resistance reduce.It is melt that existing big current fuse adopts silver or copper more, by increasing the melt local electrical resistance, reducing the response time that local quality shortens short-circuit protection.And in the present embodiment electroconductive elastic sheet 5 owing to adopt spring steel plate, can be by selecting suitable welding material for use and adjusting the local conductive area of weld seam (being slit 4), make the conductivity and the short circuit response time of current fuse realize good balance, range of application is wider.For example can increase the conductive section of first, second electric conductor 2,3 and reduce the local conductive area of weld seam and increase the thickness of electroconductive elastic sheet 5, can realize reducing the overall electrical resistance of current fuse, and increase the purpose of weld seam local electrical resistance.
Please refer to Fig. 6, during production, can carry out according to following steps:
(1) concern according to illustrated position that with first, second electric conductor 2,3 with by the electroconductive elastic sheet 5 of pre-compressive strain clamping makes long limit 52 straightenings of electroconductive elastic sheet 5 on weld jig 8, minor face 51 extends to the slit 4 between first, second electric conductor 2,3;
(2) with instrument solder(ing) paste is coated in the slit 4 uniformly, the minor face 51 of electroconductive elastic sheet 5 is coated in the solder(ing) paste, finish welding with welding equipment then, first, second electric conductor 2,3 and electroconductive elastic sheet 5 are connected as a single entity;
(3) above-mentioned first, second electric conductor 2,3 that is welded as a whole and electroconductive elastic sheet 5 are placed upper and lower box body 11,12 and fastening by screw 6, upwards fill quartz sand in the seal chamber 13, seal with screw at last from the screwed hole 112 of upper cartridge body 11 sides.
Because present embodiment adopts the stand alone type design, can the production of current fuse is independent from the production link of power brick, separately current fuse is produced in batches, not only can effectively be enhanced productivity, reduce production costs, but also can improve consistency of product.And the operability of current fuse production and maintenance is improved.
Please refer to Fig. 7, the utility model also provides a kind of electrokinetic cell, and described electrokinetic cell comprises at least two cells, is provided with at least one above-mentioned current fuse between the described cell.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
