Abstract
The utility model belongs to a lithium ion battery bank cover, which comprises battery cover, pole that passes through insulating mat and pole shim and is fixed on battery cover, injection joint fixed on battery cover, the utility model is characterized in that: periphery contact surface of said pole with insulating mat is conical surface, stop shim is provided between insulating mat and pole shim on the said pole, end end is round hole, the other end is opening groove, supersedes eccentric body of pole opening groove, simplifies process, reduces cost; pole and insulating mat adopt cone fit, increases airtightness of battery cover; in order to guarantee sealing effect of battery pack cover more effectively, tetrafluoro sealant is applied between sealing surfaces uniformly; since a stop shim is connected between pole and injection joint to prevent pole rotation, ensure safe and reliable connection of battery pole, applicable to combined cover of various large capacity lithium ion storage batteries.
Description
Technical field
The utility model belongs to the structure of battery corer technical field, particularly relates to a kind of lithium-ions battery combination cover.
Background technology
Electric automobile and hybrid vehicle development at present is very fast, and U.S. government requires the sale output value of each motor corporation's environmental-protecting type electric automobile in 2010 will reach 20%.Various countries, each major company are more and more higher to performance requirements such as the lighting of car load, environmental protection, and the research and development department of high-capacity lithium-ion storage battery is in the keen competition state thereupon.Fix a pole on the existing lithium-ions battery combination cover, the end that this pole is positioned at inside battery is just connecting battery by lug, the negative pole group, cause the short circuit of inside battery utmost point group in order to prevent that pole from rotating, pole is arranged to have eccentric face, by locking pin the hole and the battery cover of the eccentric face of pole is fixed into one, with nut pole is fixed on the battery cover, this battery cover can prevent that in a short time pole is loosening, this structure battery combination lid structure is complicated, and after using a period of time, have the holder of pole and nut pine, cause the phenomenon of battery external circuit virtual connection.
The utility model content
The utility model is for solving problems of the prior art, a kind of simple in structure, good sealing effect is provided, has been convenient to processing, and effectively prevented the lithium-ions battery combination cover that pole and nut pine are held in the palm.
The utility model for solving the technical scheme that technical problem adopted that exists in the known technology is: the lithium-ions battery combination cover, comprise battery cover, pass insulation cushion cover and pole spacers at the pole on the battery cover be fixed on fluid injection joint on the battery cover, be characterized in: described pole is a taper seat with the circumferential contact face of insulation cushion cover, and being provided with an end between insulation cushion cover and the pole pad on the described pole is that circular hole, the other end are the spline pad of open slot.
The utility model can also adopt following technical measures to realize: evenly be coated with between the mating surface of described insulation cushion cover and described battery cover between polytetrafluoroethylsealed sealed glue, described insulation cushion cover and the described pole mating surface and evenly be coated with polytetrafluoroethylsealed sealed glue; Mating holes between described insulation cushion cover and the described pole is 6 °～11 ° taper holes; It is flat that described pole taper seat small end is provided with the location that cooperates with described pole gasket for transition; Described fluid injection joint is 2 or 3; Described pole is copper alloy nickel plating or Hardmetal materials; Described pole is injection-moulded in the insulation cushion cover; Described insulation cushion cover material is the elastomeric material of anti-electric corrosion; Described insulation cushion cover material is poly-inferior acyl ammonia or polytrifluorochloroethylene; Described spline gasket material is high rigidity and high-intensity insulating material or polysulfone material.
Advantage and the good effect that the utlity model has are: because pole has removed eccentric face, simplified technology, reduced cost; Pole is a cone match with the insulation cushion cover, has improved the sealing of battery cover; For the sealing effectiveness of more effective assurance battery combination lid, evenly having applied material between sealing surface is the fluid sealant of tetrafluoro; Owing to be connected a spline pad between pole and fluid injection joint, prevented the pole rotation, guarantee the advantage such as safe and reliable of battery electrode column connection, be applicable to the combination cover of various high-capacity lithium-ion storage batterys.
