Abstract
The utility model relates to the technical field of a lithium ion battery, and in particular relates to an insulation flame retardant protection device of an aluminum-shell laminated battery pole. The insulation flame retardant protection device is an insulation sleeve which can be sleeved on a pole of an aluminum-shell laminated battery and can completely sleeve the pole of the aluminum-shell battery. The insulation flame retardant protection device of the aluminum-shell laminated battery pole is safe to use, high in reliability, recyclable, low in machining cost and convenient to use, and can effectively protect the pole of the battery under the states of application, storage or transportation, can prevent the short circuit and can reduce the safety potential danger.
Description
Technical field
The utility model relates to technical field of lithium ion, is specifically related to a kind of aluminum hull laminated batteries pole insulation fire-resisting protection device.
Background technology
Lithium ion battery compare with the battery of other types such as plumbic acid, cadmium nickel have that specific capacity is big, operating voltage is high, charging rate is fast, operating temperature range is wide, have extended cycle life, volume is little, advantage such as in light weight.At present, be widely used in fields such as mobile phone, notebook computer, electric tool, and its range of application more and more widely.
Along with the maturation of electric vehicle engineering and perfect day by day, the dream that electric automobile, hybrid vehicle are come into daily life has become possibility, and is breeding huge business opportunity in the process that electric automobile is popularized.And the quality of vehicle-mounted great-capacity power battery performance directly affects the overall performance of electric automobile.This is electric automobile vehicle mounted dynamic battery have higher requirement (such as will having higher fail safe, more outstanding performance, weight is lighter).The reliability of battery, fail safe also are that to make the technological difficulties in the storage process and the fail safe of emphasis, particularly battery and the protection of positive and negative terminals all be directly to influence the important step of battery performance and potential safety hazard to great-capacity power battery.
When if lithium battery causes the both positive and negative polarity short circuit in use or storage process, battery container will can sharply rise by heating temp, will cause the decay of battery performance and cycle life, and internal resistance increases, influence the various performance parameters of lithium battery, finally cause battery can't continue to use.
The now big vehicle-mounted dynamic lithium battery positive and negative terminals of capacity not protection does not have insulator yet, and positive and negative terminals is had not a particle of protective effect, causes the both positive and negative polarity short circuit easily, and very big potential safety hazard is arranged.
The utility model content
The purpose of this utility model is that a kind of aluminum hull laminated batteries pole insulation fire-resisting protection device is provided in order to overcome shortcoming of the prior art; the pole that is intended to solve existing aluminum hull laminated batteries not protection does not have the insulator protection yet; cause the both positive and negative polarity short circuit of battery easily, have the problem of potential safety hazard.
A kind of aluminum hull laminated batteries pole insulation fire-resisting protection device, it is one can be set on the pole of aluminum hull laminated batteries and the pole of described aluminum hull laminated batteries can be placed in fully insulating case in it.
The top of described insulating case is provided with wiring hole.
Described wiring hole is arranged on the top centre of described insulating case.
Inwall at described insulating case has the thread groove structure that matches with described pole.
It is processed by an injection moulding of plastic material.
It is injection molded by polyethylene BP material.
The utility model aluminum hull laminated batteries pole insulation fire-resisting protection device, the safety and reliability height, and can recycle; processing cost is low, and is easy to use, under the situation of using, store, transporting at battery; can protect the pole of battery effectively, reduce potential safety hazard.

Figure 1 shows that the structural representation of the aluminum hull laminated batteries pole insulation fire-resisting protection device that the utility model provides.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with accompanying drawing.
Referring to Fig. 1, the figure shows the structure of a kind of aluminum hull laminated batteries pole insulation fire-resisting protection device that the utility model provides.For convenience of explanation, only show the relevant part of the utility model.
A kind of aluminum hull laminated batteries pole insulation fire-resisting protection device, it is one can be set on the pole of aluminum hull laminated batteries and the pole of described aluminum hull laminated batteries can be placed in fully insulating case in it.
Referring to shown in Figure 1, described insulating case comprises a body 1, is provided with circular edges along 2 in described body 1 bottom, and described body 1 is the hexahedron shape.
Further, the top of described insulating case is provided with wiring hole.
More excellent, described wiring hole is arranged on the top centre of described insulating case.
Wherein, has thread groove structure with described pole respective outer side edges at the inwall of described insulating case.By being provided with the thread groove structure,, can prevent that this insulating case from coming off under the situation of using, storing or transport by cooperating with battery electrode column.
It is processed by an injection moulding of plastic material.
It is injection molded by polyethylene BP material.
The utility model aluminum hull laminated batteries pole insulation fire-resisting protection device, the safety and reliability height, and can recycle; processing cost is low, and is easy to use, under the situation of using, storing or transport at battery; can protect the pole of battery effectively, reduce potential safety hazard.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
