Abstract
The utility model discloses an insulation device for a battery pack. The insulation device comprises an insulation board and an insulation meson which are arranged on a top cap of the battery pack in a press-fitting manner. The insulation device is characterized in that the insulation board and the insulation meson are respectively provided with holes corresponding to connection points of the positive and negative polarities of the battery pack in position; the central part of the insulation board is provided with a strip-shaped groove; and the middle part of the insulation meson is provided with a bulge matched with strip-shaped groove. By virtue of the battery pack, the problems of short circuit caused by connection between the battery pack and a connection piece as well as short circuit caused by contact between positive and negative polarity lugs of the battery pack are effectively solved, the qualified rate of the battery pack is improved, production waste is reduced, and the production safety is necessarily guaranteed.
Description
Technical field
The utility model belongs to the technical field that battery pack is processed process in groups, relates in particular to a kind of seal that is used for battery pack.
Background technology
The lithium-ion-power cell that we produce owing to present stage can't be realized the compatibility of capacity and multiplying power on performance, so the normally back use in groups of used for electric vehicle lithium ion battery.Usually battery pack all is that cell is taked parallel connection through metal connecting sheet or the mode of series connection is formed by connecting.Simultaneously, the operation of subsequent assembly for ease, usually the battery pack of little module draw just/negative lug is long, and because used for electric vehicle lithium ion battery group is series-parallel mode through repeatedly makes up, operation is various.Like this; In the production and assembly process of battery pack; Be easy to occur owing to outside human factor cause battery container with just/contact caused when negative pole was connected short circuit; And the positive and negative lug contact short circuit of little module battery pack, bring a lot of unsafe factors and unnecessary material waste to production.
The utility model content
The purpose of the utility model is in order to remedy the deficiency of prior art; A kind of seal that is used for battery pack is provided; Solved being connected and the short circuit that causes between battery pack and the brace; And the short circuit that causes of the contact between the positive and negative lug of battery pack, there is potential safety hazard, problems such as material waste.
The utility model is realized through following technical scheme:
A kind of seal that is used for battery pack; Include the insulation board and insulation meson that are fitted on the battery pack top cover; It is characterized in that: have the corresponding perforate in both positive and negative polarity tie point position on said insulation board and the insulation meson with battery pack; The middle part of said insulation board is provided with bar-shaped trough, and the middle part of said insulation meson is provided with the convexity that matches with bar-shaped trough.
The convex cross section of described insulation meson is an arch, and height is at 5mm～15mm, and bottom width is 8mm～10mm; And the insulation meson can be 2,3,4 and or how also, concrete parallel way is adjusted according to the parallel way of battery pack.
The width of the bar-shaped trough at described insulation board middle part is 8mm～10mm, and length is according to the length adjustment of battery pack.
The material of said insulation board is an epoxy plate, and the material of said insulation meson is engineering plastics or the resin with fire-retardant composition.
Its principle is: the seal between top cover and the brace is made up of the insulation meson and the epoxy plate that contain flame-retardant composition; And be attached on the top cover through the colloid of insulation meson bottom, can prevent in process of production to cause brace and top cover contact short circuit owing to be welded to connect the sheet misoperation; Seal between the both positive and negative polarity mainly is to pass the middle square groove of epoxy plate by the bossing on the insulation meson that contains flame-retardant composition; At a distance from the middle of the both positive and negative polarity of battery pack; The two poles of the earth are separated, can prevent in assembling process because the both positive and negative polarity contact short circuit that misoperation causes.
The utility model has the advantages that:
The utility model has effectively solved being connected and the short circuit that causes between battery pack and the brace; And the short circuit that causes of the contact between the positive and negative lug of battery pack; Improved battery qualification rate in groups, reduced and produced waste, necessary guarantee is provided for simultaneously the fail safe of producing.
