Specific embodiment
In order to the technical solution of the utility model is explained further, this utility model is entered below by specific embodiment Row elaborates.
As shown in Fig. 2 being a kind of square nickel-metal hydride battery group that this utility model discloses, including square casing 1, electrode converging Block 2, conductive plate 4 and plural monomer electricity stamen 3.
Plural monomer electricity stamen 3 is sequentially placed in square casing 1, passes through conductive plate 4 between adjacent two monomer electricity stamens 3 Isolation, conductive plate 4 opens up intercommunicating pore 41 makes each monomer electricity stamen 3 connection share electrolyte.
Monomer electricity stamen 3 includes multiple positive plates 31, multiple negative plate 32 and continuous rugosity barrier film 33, positive plate 31 and negative Pole plate 32 is respectively placed in the both sides of continuous rugosity barrier film 33 and is separated completely.Positive plate 31 and negative plate 32 part are stretched out It is in close contact with conductive plate 4 after continuous rugosity barrier film 33, thus realizing the series connection between each monomer electricity stamen 3.Square casing 1 Two ends are respectively mounted electrode converging block 2, for connecting power supply with external member.
Wherein between positive plate 31 and positive plate 31, and between negative plate 32 and negative plate 32, then pass through continuous rugosity Barrier film 33 fold of itself separates, and the version of preferred monomer electricity stamen 3 has following two.
The first, as shown in figure 3, every piece of positive plate 31 and negative plate 32 doubling are V-shaped.Positive plate 31 is plugged on continuously On the crest 331a of rugosity barrier film 33 side fold, between adjacent two positive plates 31 the one crest 331a in interval be used for by each just Pole plate 31 separates.Negative plate 32 is plugged on the crest 331b of continuous rugosity barrier film 33 opposite side fold, adjacent two negative poles Between plate 32, one, interval crest 331b is used for separating each negative plate 32.This kind of situation when being stressed, positive plate 31 He To mutually restrict between negative plate 32, therefore between positive plate 31 and negative plate 32, positional stability is good, larger power can be born, Evenly tight with the contact of following conductive plates 4.
Second, as shown in figure 4, positive plate 31 and negative plate 32 are in flat shape.Each positive plate 31 is plugged on continuously respectively At the trough 332a of rugosity barrier film 33 side fold, each negative plate 32 is plugged on continuous rugosity barrier film 33 opposite side pleat respectively At the trough 332b of wrinkle.This kind of situation, mutually restricts few, during by larger pressure, partly just between positive plate 31 and negative plate 32 Pole plate 31 and negative plate 32 also unbalance stress and tilt, though can contact with following conductive plates 4, contact force inequality.
As shown in figure 1, multiple monomer electricity stamens 3 and one layer of organic insulation of electrode converging block 2 outer cladding seal gallbladder 5, make electrode The electric stamen 3 of block 2, conductive plate 4 and plural monomer that confluxes forms the entirety of a sealing.
Wherein two electrode converging block 2 the inner has radial flange 21, and the two ends that organic insulation seals gallbladder 5 are coated on radial convex On edge 21.
Radial flange 21 is located at and is provided with insulating pad 6 on organic insulation sealing gallbladder 5, is provided with insulating pad 6 Metal platen 7, square casing 1 is metal shell.
During installation, first determine the quantity of monomer electricity stamen 3 by required voltage size, then by each monomer electricity put well in order The block set that confluxes at stamen 3, conductive plate 4 and two ends, is together inserted in heating pyrocondensation in the thermoplastic tube with machine insulated enclosure gallbladder 5, finally Formed and there is the set of cells group stamen that organic insulation seals gallbladder 5 overcoat.Set of cells group stamen is placed in square casing 1, then two ends Insulating pad 6 and metal platen 7 is put successively at radial flange 21.Apply inside thrust to metal platen 7, thrust reaches and sets After definite value(I.e. positive plate 31 and negative plate 32 respectively with conductive plate 4 intimate electrical contact), by metal platen 7 and square casing 1 Spot welding is fixed.Finally in square casing 1 two ends packing matcrial.
At least one of two electrode converging blocks 2, open up the installing hole 22 connecting with monomer electricity stamen 3, peace in installing hole 22 Dress can not answer relief valve 8.As shown in figure 5, relief valve 8 can not be answered include valve body 81, spring base 82, compression spring 83, valve seat 84 With ball valve core 85.In valve body 81, outer end is respectively mounted spring base 82 and valve seat 84, and spring base 82 opens up and connects with cell stamen 3 Perforation 86, the two ends of compression spring 83 are separately mounted on spring base 82 and ball valve core 85.Valve seat 84 inner surface is formed and ball valve The spherical balls valve element 85 that core 85 combines, in the presence of compression spring 83, is closely pressed on valve seat 84 inner surface and completes to seal.
Before installation can not answer relief valve 8, first pass through this installing hole 22 to set of cells group stamen inside evacuation, then pour into Electrolyte, electrolyte, by flowing into each monomer electricity stamen 3 after the intercommunicating pore 41 of conductive plate 4, makes each monomer electricity stamen 3 share electrolyte, And common gas.Then install and can not answer relief valve 8.
After set of cells life-time service, the super safety value of pressure in valve body 81(More than the Opening pressure that typically can answer relief valve Value)When, ball valve core 85 backs down valve seat 84, opens and can not answer relief valve 8, discharges gas or liquid.Because external pressure is less, with And in the presence of the extrapolability of compression spring 83 so that ball valve core 85 can not possibly self-return, battery failure.Avoid existing electricity Pond pressure release repeatedly, causes irreversible injury to inside battery, improves the probability that reverse electrode phenomena occurs, and reduces cell safety hidden danger.
Wherein electrode converging block 2 also opens up screwed hole 23, and screwed hole 23 is used for installing screw rod 24, and screw rod 24 is provided with crimping Nut 25.By the cooperation of screw rod 24 and crimping nut 25, for connecting with external structure.
The present embodiment passes through multiple monomers electricity stamen 3 is directly connected and is placed in same square casing 1, each monomer electricity stamen Connected by conductive plate 4 between 3.Rather than first make complete cell as prior art, then cell is led to Cross multiple structure such as lug, electrode block, electrode column and electric connection block to connect, the set of cells that therefore this utility model provides drops significantly Low internal resistance.
Why monomer electricity stamen 3 of the present utility model can directly connect, and it is critical only that the positive plate of each monomer electricity stamen 3 31 and negative plate 32 all separated completely so that positive plate 31 and negative plate 32 do not connect by one piece of continuous rugosity barrier film 33 Tactile probability, that is, positive plate 31 and negative plate 32 can bear longitudinal pressure it is ensured that positive plate 31 and negative plate 32 and conductive plate 4 Can closely make electrical contact with.Simultaneously the fold of continuous rugosity barrier film 33 can also by between positive plate 31 and positive plate 31, and It is spaced apart between negative plate 32 and negative plate 32.
These are only preferred embodiment of the present utility model, not the restriction to protection domain of the present utility model.All according to The equivalent variations that the mentality of designing of this case is done, each fall within the protection domain of this case.
