Abstract
The utility model discloses a metal casing secondary battery terminal sealed insulation structure, and is composed of a metal casing battery cover and terminal of a secondary battery, and between which are provided with an insulating mat; the insulating mat and an O-shaped seal ring are matted from internal to external between the internal side of the battery cover and the terminal, of which the O-shaped seal ring is arranged higher than the insulating mat, and is in compression deformation under the using state; a T-shaped insulating mat is arranged between the external side of the battery cover and the terminal binding bolt for compression. By using the battery of the utility model, the cost is cost, and the insulatibity between the battery terminal and the metallic casing is excellent, and has excellent sealability.
Description
Technical field
The utility model relates to the sealed insulation structure of battery electrode column, relates in particular to a kind of sealed insulation structure of using the metal shell secondary cell pole of liquid electrolyte.
Background technology
Cylinder type secondary battery adopts metal shell more both at home and abroad at present, and electrolyte again more adopts liquid electrolyte, and has only one deck insulation cushion between the battery cover of metal shell and pole, so often there is the solution leakage phenomenon to take place, needs to be resolved hurrily.This just requires should insulate between pole and the housing, again good airproof performance.
Summary of the invention
The purpose of this utility model provides a kind of sealed insulation structure that guarantees the metal shell secondary cell pole of good airproof performance between metal shell battery cover and pole.
For achieving the above object, the utility model is taked following design: a kind of metal shell secondary cell electrode column sealing insulation system, the metal shell battery cover and the pole that comprise secondary cell, the two is equipped with an insulation cushion, also be lined with insulation cushion and O RunddichtringO between battery cover inboard and pole from the inside to the outside, the O RunddichtringO is higher than insulation cushion and is the crimp attitude under user mode; The battery cover outside and compressing with being furnished with T type insulation cushion between the pole fastening bolt.
The utility model has the advantages that: adopt the lithium ion battery low cost of manufacture of this kind structure, good insulation preformance between battery electrode column and the metal shell has excellent sealing performance.
Description of drawings
Fig. 1 is electrode column sealing insulation system figure of the present utility model.
Embodiment
As shown in Figure 1, the utility model metal shell secondary cell electrode column sealing insulation system, the metal shell battery cover 4 and the pole 1 that comprise secondary cell, the two is equipped with an insulation cushion 2, between battery cover inboard and pole, also be lined with insulation cushion 5 and O RunddichtringO 3 from the inside to the outside, battery cover 4 outsides and compressing with being furnished with T type insulation cushion 6 between the pole fastening bolt 7.
Above-mentioned O RunddichtringO 3 should be higher than insulation cushion 5, and in the process that use compresses, under the effect of pole fastening bolt 2 and insulation cushion 5,2 and T type insulation cushion 6, extruding O RunddichtringO 3 is deformation state, makes the sealing effectiveness of structure satisfy sealed insulation requirement between pole and metal shell.
Described T type insulation cushion 6 can guarantee that pole 1 and pole fastening bolt 7 and battery cover 4 be not by short circuit.
Its assembling process: successively insulation cushion 2, O RunddichtringO 3, insulation cushion 5 are sleeved on pole 1, the pole 1 that insulation cushion, sealing ring have been installed is sleeved on the battery cover 4,, then compress assembly of formation with pole fastening bolt 7 by last T type insulation cushion 6.
The material of described pole 1 and battery cover 4 can be a metallic aluminium.
Insulating material such as described insulation cushion 2,5 and T type insulation cushion 6 usefulness polytetrafluoroethylene, polyvinyl chloride are made; O RunddichtringO 3 selects for use acid and alkali-resistance, resistant to elevated temperatures specific rubbers such as acrylic acid fat, Ethylene Propylene Terpolymer, fluorine glue to make.
In the embodiment that adopts technical solutions of the utility model making 40Ah, 30Ah, 25Ah, 17Ah column lithium ion battery, sealed insulation is functional between the battery cover of metal shell and pole, battery container is all not charged, and battery the solution leakage phenomenon all do not occur in the process of using.
