Fig. 2 is the nickel-hydrogen secondary cell structural representation of an execution mode.
Embodiment
Below in conjunction with embodiment and accompanying drawing, nickel-hydrogen secondary cell is described in further detail.
See also Fig. 1, nickel-hydrogen secondary cell 100 housings 110 of an execution mode, pole piece 120, insulation barrier assembly 130, lug 140 and cap assemblies 150.
Housing 110 comprises bottom 112 and the sidewall 114 that links to each other with the bottom, housing, and bottom 112 forms open-topped cavity with sidewall 114, and cavity can be cylinder, cuboid or square etc., is used for accommodating the each several part assembly of battery.Housing 110 is the box hat of nickel plating, gets rusty preventing, in other embodiments, also can be box hat or aluminum hull.Bottom 112 and sidewall 114 can be one-body molded, form open-topped hollow cavity, adopt disposable punch forming, and bottom 112 and sidewall 114 form seamless link, can better accommodate an assembly.On sidewall 114, be provided with the protuberance 116 that extends to enclosure interior near top open part.Protuberance 116 can also can form protuberance 116 by modes such as welding or riveted joints at sidewall 114 by with inwardly extruding formation of sidewall 114 when sidewall 114 moulding after sidewall 114 moulding.Protuberance 116 can be used for supporting cover assembly 120.
Pole piece 120 is contained in the housing 110, and is fixed on the bottom 112 of housing 110.Pole piece 130 contacts with the inwall of sidewall 114, and the diameter at the top of pole piece 130 is slightly less than the internal diameter of housing 110, leaves the space and be used for placing insulation barrier assembly 130 between pole piece 120 and housing 110.
Insulation barrier assembly 130 comprises side wall portion 132 and the isolation part 134 that links to each other with side wall portion 132.See also Fig. 1, side wall portion 132 can contact with sidewall 114, and the top of side wall portion 132 and the downside of protuberance 116 offset at this moment, in the bottom insertion pole piece 120 and the space between the housing 110 of side wall portion 132.See also Fig. 2, side wall portion 132 can not contact with sidewall 114 yet, this moment, side wall portion 132 had certain distance with sidewall 114, and the top of side wall portion extends upwardly to cap assemblies 150 and offsets, isolation part 144 extends to sidewall 114 to sidewall 114 and contacts, and in the space that sidewall 114 inserts between pole piece 120 and the housing 110.Isolation part 134 is isolated in the downside of isolation part 134 with pole piece 120, but offers intercommunicating pore 136 simultaneously, and the diameter minimum of intercommunicating pore 136 is 1 millimeter, be to the maximum housing 110 internal diameter 95%, pass and the gases output that produces in the pole piece 120 can be gone for lug.Insulation barrier assembly 130 and cap assemblies 150 form the separate cavities 138 of hollows.The size of separate cavities 138 is relevant along the length of the direction of sidewall 114 with side wall portion 132, and the length of side wall portion 142 is more long, and the space of the separate cavities 138 of formation is more big.The length of side wall portion 132 can arrange as required, and in the present embodiment, the length of side wall portion 132 is 1/10 ~ 7/10 of sidewall 114 length.When accident appearred in battery, when producing gas in the housing 110, separate cavities 138 can have enough space savings gas, avoids battery explosion.The barrier assembly 130 that insulate simultaneously can directly adopt polypropylene (Polypropylene, PP), polyamide (polyamide, PA), polyethylene (polyethylene, PE) or polyvinyl chloride (polyvinylchloride, PVC) etc. insulating material is made, the insulation barrier assembly 130 also can adopt supporting role preferably steel make, put insulating sleeve then; Play insulating effect, cause battery short circuit for preventing that lug 140 from contacting with housing 110.
Lug 140 is arranged on the top of pole piece 120.The metallic conductor of lug 140 essence for from pole piece 120, both positive and negative polarity being extracted.Lug 140 passes intercommunicating pore 136 and separate cavities 138 and is electrically connected cap assemblies 150 and pole piece 120.
Cap assemblies 150 is arranged on the protuberance 116, offsets with protuberance 116, is used for the open top of seal casinghousing 110.On cap assemblies 150 and protuberance 116, seal 152 can be set, be used for seal cover assembly 150 and housing 110.Seal 152 can be sealing gasket or fluid sealant.
In the above-mentioned nickel-hydrogen secondary cell 100, comprise housing 110, pole piece 120, insulation barrier assembly 130, lug 140 and cap assemblies 150.Pole piece 120 is contained in the housing 110, is fixed on the bottom 112 of housing 110; Insulation barrier assembly 130 is kept apart lug 140 and housing 110, and the intercommunicating pore 136 that lug 140 passes insulation barrier assembly 130 is electrically connected cap assemblies 150 and pole piece 120.And insulation barrier assembly 130 and cap assemblies 150 form the separate cavities 138 of hollows.Press increase to cause the danger of exploding in can avoiding when producing gas in the housing 110, simultaneously, lug 140 is arranged in the separate cavities 138 of insulation barrier assembly 130, has avoided lug 140 in use, because the accident distortion contacts the generation that causes short circuit with housing 110.Nickel-hydrogen secondary cell 100 can be preferably fixedly pole piece 120, isolate lug 140 and housing 110, simultaneously simple in structure, number of fitting parts is few, therefore can reduce the installation step of battery.
The above embodiment has only expressed execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
