(2) background technology
Electrokinetic cell is the battery that uses with being used as power, the big capacity energy storage of the capacity that is often referred to more than 10 ampere-hours (Ah) is with battery (comprising metal fuel battery, storage battery, ultracapacitor etc.), it is widely used on electric tool, electronic toy, electric bicycle, electric automobile, the electric ship, as its energy source.Commonly used have lead acid accumulator, a lithium-ions battery.Because battery cell voltage is low, or off-capacity, can not satisfy the use needs, a plurality of cell serial or parallel connections need be used usually, this just needs to use suitable connection lead, also is (power) cell connector.
The existing connection lead that is used for the electrokinetic cell serial or parallel connection is that cell connector mainly contains three kinds: first kind is with traditional copper core cable, it is cut into a bit of of respective length by two cell distance between electrodes, corresponding battery electrode splicing ear forms on two ends press-fit again, so its composition generally comprises splicing ear, copper core and outpacking rubber and overlaps three parts; Second kind is to use the metal wire knitted band, be cut into a bit of of respective length by two cell distance between electrodes, corresponding battery electrode splicing ear and punching on two ends press-fit again, in order to insulate, generally also can be outside the metal wire knitted band suit heat-shrink tube, so its composition generally comprises splicing ear, conductive core line (metal wire knitted band) and overcoat heat-shrink tube three parts; The third then is special, normally with the very thin conducting metal sheet material (being generally copper material) of the about 0.3～0.7mm of thickness, with the method for punching press its punching out is become two ends band connecting hole, length and two sheet metals that the cell distance between electrodes is suitable, again 3～5 such foils alignment overlap (the monolithic conductive cross-sectional area is not enough), position suit heat-shrink tube pyrocondensation is tightened up and is formed between two connecting holes of sheet metal, therefore it forms the slightly letter than the former two, have only two kinds of assemblies of special sheet metal and heat-shrink tube, its splicing ear directly on the conductive core line sheet material punching out process, become one with conductive core line, thereby designs simplification.
The deficiency of its existence is: at first, these connect conductor structure and manufacture craft slightly complicated, and cost is higher; Secondly, serious is, the conductive core line of these leads is made up of multiply fine wire or multi-disc foil, and it is too big to expose aerial surface area, and oxidized easily later on, corrosion of experience a period of time and can not continue to use must replacing.
(3) summary of the invention
The objective of the invention is: improve above-mentioned deficiency, invent a kind of structure relative with manufacture craft simple, cost is lower, exposed surface area is little, the corrosion-resistant durable electrokinetic cell of resistance to oxidation connects lead.
For achieving the above object, the present invention adopts following technical scheme: single cell battery connecting strip, be a kind of connection lead that is used for the electrokinetic cell serial or parallel connection, comprise splicing ear, conductive core line, it is characterized in that: its conductive core line only adopts a metal sheet or a metal bar.
Owing to taked above-mentioned technical scheme, the present invention compares with existing technology, has that structure and manufacture craft are simple, cost is low, and exposed surface area is little, the corrosion-resistant durable advantage of resistance to oxidation.
(4) description of drawings
Contrast accompanying drawing below, the embodiment of the invention is described in further details.
Fig. 1 is the embodiment of the invention 1 structural representation.
Fig. 2 is the embodiment of the invention 2 structural representations.
(5) embodiment
As shown in Figure 1; generally speaking the embodiment of the invention 1 is one and connects lead; the serial or parallel connection that is used for electrokinetic cell; comprise splicing ear 1, conductive core line 2; in order to insulate; usually also will be outside conductive core line 2 suit heat-shrink tube 3; in the present embodiment; conductive core line 2 only adopts a metal sheet; the method of common employing punching press processes the required hole, garden of battery electrode connection and (is used to lock screw at its two ends; Kong Zhouying chamfering, deburring are in order to avoid it hinders joint face to fit), constitute splicing ear 1, and be shaped to required shape (as figure).Certainly, this piece metal sheet is enough thick, so that enough sectional areas are arranged, satisfies electrokinetic cell output power needs.Concrete thickness can calculate according to correlation formula.
Fig. 2 is the embodiment of the invention 2, is another kind of situation of the present invention.Embodiment 2 also comprises splicing ear 1, conductive core line 2, in order to insulate, usually also will be outside conductive core line 2 suit heat-shrink tube 3.Different with embodiment 1, the conductive core line of embodiment 2 is a metal bar but not sheet material, and certainly, this root metal bar is wanted enough slightly, so that enough sectional areas are arranged, satisfy electrokinetic cell output power needs.Concrete external diameter can calculate according to correlation formula.Because conductive core line 2 is bars; splicing ear 1 is the sheet shape of broad; the two differences in shape is too big; be difficult for realizing directly processing generation splicing ear 1 (unless adopting special thermoforming process) by conductive core line 2; therefore the two is not one usually; must adopt the pressure assembling to link together by specific purpose tool (Crimping Pliers), good in order to guarantee the junction contact, usually also will be with the junction wicking.This makes its structure and manufacture craft than embodiment 1 slightly complicated, but its conductive core line is yielding thereby use and show slightly convenient than embodiment 1, and exposed surface area is littler, can be used for the connection of lead-acid power accumulator.
If the present invention is used for the connection of lead-acid power accumulator, because of can the overflow sulfuric acid of severe corrosive of battery, conductive core line should adopt copper material, and with the splicing ear wicking.Connect if be used for lithium-ion-power cell, do not contact corrosive substances such as sulfuric acid during use, conductive core line 2 can attempt adopting the aluminum or aluminum alloy material, can further reduce cost like this; In addition, can carry out polishing to connection end face 4, this helps to connect fitting tightly of end face 4 and battery electrode face, and enhancement connects the also effective prevention air of effect, steam enters the connection end face is caused oxidation, corrosion.
Certainly, adopt the present invention, conductive core line 2 monolithics or single sectional area increase, and intensity increases, and is not yielding, in case run into two holes between battery electrode not coplanar, dislocation, will be difficult for assembling.Solution is: guarantee battery manufacturing and series-parallel assembly precision, guarantee the pitch of holes and the same flatness of two battery electrodes; Guarantee two of the cell connector same flatness that connect end faces simultaneously, enlarge the aperture of connecting hole, guarantee splicing ear length and be beneficial to its distortion, find have problem to finely tune when using with the radian that is connected between the conductive core line, etc.In a word, be the accuracy of manufacture and the tolerance that improves battery and intercell connector, and adjust flexibly in use.
Technical scheme of the present invention can be generalized to like product: electric motor car, electric ship electric power transfer wire.Common and the complete use of the present invention (because the electrokinetic cell connection in series-parallel is mainly used in electric motor car, electric ship) of the latter, and in essence, with the invention belongs to same series products: be connected lead, it also comprises splicing ear, conductive core line, electrokinetic cell and electric motor car, the motor of ship, power consumption equipment are coupled together, the electric power of transmission electrokinetic cell can be referred to as electronic cable.Present this electronic cable, usually usefulness is the filament cable, its conductive core line is made up of many fine wires, tinsel footpath＜0.5mm, use the filament cable, mainly be to consider its heart yearn jewelry, expensive clothing and other valuables, be convenient on electric motor car, ship, install, but ignored too big, the easy problem of deterioration by oxidation of its exposed surface area, therefore also should improve.Improved plan has two kinds: a kind of crin cable that is to use, and its conductive core line adopts the crude metal silk thread, and tinsel footpath 〉=0.5mm is referred to as the electronic cable of crin; Another kind just is to use the single-core cable line, and its conductive core line only adopts a metal sheet or a metal bar (enough thick), is referred to as the electronic cable of single core.After the improvement, the exposed surface area of the conductive core line of electronic cable reduces greatly, is difficult for oxidized, corrosion, thereby prolongs greatly useful life.Although line footpath overstriking causes cable intensity to increase, be difficult for bending and installs, this influence is of short duration, can overcome with methods such as pre-formed and back mechanical shapings, takes a long view, and it is useful doing like this.
Obviously, the electronic cable of single core not only can be used for electronic car and boat, also can be used as common electric power transfer lead, becomes the single-core power cables line, comprises splicing ear, conductive core line, can compare with current common electric power cable line.Current common electric power cable line, the conductive core line cross section is at 6mm usually
2When following, just adopt the single piece of metal wire rod, the cross section is at 6mm
2When above, adopt many heavy wire to lump together usually, consider that mainly the cross section is at 6mm
2When above,
If adopt single piece of metal wire rod or bar, intensity is too big, not flexible and installation.Do like this and show slightly conservative in fact.In fact, as conductive core line sectional area＞6mm
2The time, as reach 50mm
2(～Φ 8mm) only adopts a metal bar, though its bending and installation show slightly difficulty, problem is little in fact; And conductive core line is when only adopting a metal sheet, core section is long-pending can be discussed, because still do not have the single-core power cables line that heart yearn is a sheet type at present, and sheet material can be done widely and flat, be convenient to flexible bending, connection and installation, reasonable purposes should be arranged.
Adopt the advantage of single-core power cables line still to be: to reduce the exposed surface area of conductive core line, slow down its aerial oxidation, corrosion rate, thereby prolong the useful life of power cable.
The present power cable that uses, standardization seriation as using the single-core power cables line, can be set up corresponding new series and standard with reference to it.
Set up after the corresponding new series and standard, the single-core power cables line can be made long coiled strip, but the electronic cable of single core is generally the fixed length material, because electric motor car, ship space are limited.The latter can be raw material with the former, processes according to designing requirement is pre-formed, and also scene processing when mounted or reprocessing, palpus is noted the bending radius requirement when processing and installation, in case overbending is damaged conductive core line or outsourcing insulation.
Above-mentioned single cell battery connecting strip, the electronic cable of single core, the electronic cable of crin, single-core power cables line, and the common power cable that uses at present, etc., all be the lead that is used for transmitting the power electricity, can be referred to as the power transfer wire.These leads are all wanted the bigger operating current of bearing ratio in use, and conductive core line heating, easy oxidation and aging problem all can be arranged, and adopt the present invention, are one of means that address this problem.But can be not limited thereto in fact, in fact, if on the using method of power transfer wire, work hard, also can obtain certain effect, as: adopt methods such as gluing (certainly, this glue should be that be easy to peel off, thin, be beneficial to maintenance, heat radiation), encapsulation process (sealing the outlet of insulating sleeve) is carried out in the wire interconnecting piece position, make conductive core line and isolate from outer air, for the conductive core line oxidation that delays lead and aging, extension lead useful life, also can play certain useful effect; Can also adopt methods such as gluing, encapsulation process is carried out in the wire interconnecting piece position, make connecting portion also with isolate from outer air, this is for the oxidation of the connecting portion that delays lead and aging, in the useful life of extension lead connecting portion, also can play certain useful effect; Even if blow-by, only adopt heat-shrink tube, outlet, the pyrocondensation of wire interconnecting piece position of the insulating sleeve of lead are sealed, prevent wire interconnecting piece position short circuit (it is particularly important that this point connects occasion at battery electrode) for intercepting the air oxidation burn into, certain useful effect is all arranged, be worth adopting.
Splicing ear wicking, connecting hole chamfering, deburring, link mirror polish, pre-formed, seal insulating sleeve outlet etc., can list the order requirement of cell connector, electronic cable in, be easy to use like this.
The power transfer wire should be avoided using and easily decompose the insulating barrier that produces corrosive gas, and as polyvinyl chloride (PVC), produce hydrogen chloride (HCl) corrosive gas easy the decomposition, and conductive core line is caused deep-etching, should avoid use.Regrettably: present many power transfer wires should improve using this insulating barrier.
