Abstract
The utility model relates to an internal insulating gasket structure of a battery and particularly relates to an internal upper insulating gasket structure of a lithium-ion power battery. The structure is characterized in that the whole insulating gasket is a concave structure, and a portion of the concave structure, which extends along the length direction, is a plane; stopping plates which are perpendicular to the plane are arranged at two ends of the concave structure and inside the concave portion respectively and divide the whole insulating gasket into two concave structure bodies; and through-holes are arranged on stopping plates, so that two concave structure bodies are communicated with each other and the concave structure is communicated with the outside. The structure can meet discharging and insulating requirements of a large current capacity power battery of three multiplying power, simultaneously, the assembly efficiency of the battery is greatly improved, the assembly process procedure is simplified, the production cost and the product cost are reduced, the assembly quality of products is improved, and the market competitiveness of products are enhanced.
Description
Technical field
The utility model relates to insulation spacer structure in a kind of battery, especially a kind of lithium-ion-power cell built-in electrical insulation Upper gasket structure.
Background technology
At present; The range of application of lithium ion battery more and more widely; Particularly capacity is fast-developing especially in the development of the above battery of 50Ah in recent years; Therefore also to the built-in electrical insulation of battery utmost point group, comprise between utmost point group and the housing, the insulation between pole and the cap, and battery utmost point group positioned internal etc. has proposed higher requirement.
If in use the utmost point group of lithium battery and housing are short-circuited and can produce serious safety problem, even can cause battery explosion, thus the insulation safety property of battery be electrokinetic cell make and design process in key technology emphasis and requirement.Slim lower gasket insulation simple in structure, function singleness that the most at present big vehicle-mounted dynamic lithium battery internal poles of capacity group insulation are generally adopted; This insulation mode only produces insulation effect to a certain degree; Can't more effectively play the effect of insulation fully, thereby have very big potential safety hazard.Therefore a kind of last insulation spacer to lithium-ion-power cell internal poles group location and insulating effect of specialized designs is to have very much the production practices meaning.
The utility model content
The purpose of the utility model is through insulation spacer structure on a kind of lithium-ion-power cell inside is provided, and then has solved the problem that exists in the above-mentioned background technology.
For solving the problems of the technologies described above, the technical scheme of the utility model is: described insulation Upper gasket structure is the two ends composite type, and global shape is concave structure, and the part that concave structure extends along its length is the plane.Be respectively arranged with in two ends of concave structure and the spill thereof and the perpendicular catch in above-mentioned plane, this catch is divided into two concave structures with described insulation spacer overall structure; Said catch is provided with penetrating hole, makes between two concave structures, communicates between concave structure and the outside.
The concave structure of the utility model can be rectangle, uses PP to be material.
When actual design; Can with the utility model and cell integrated shape and battery electrode column is corresponding design; With playing the location pole after the said pad combination, be used with battery utmost point group pole insulating surfaces, and with shell wall and the effective insulating effect of isolating of utmost point group; And then guaranteed greatly the fail safe of battery to prevent the generation of short circuit phenomenon.The utility model can satisfy the electric current great-capacity power battery discharge insulating requirements of 3 multiplying powers simultaneously; Improve simultaneously the battery efficiency of assembling greatly, simplify the assembly technology operation, reduce the cost of production and product; Improve product assembly quality, strengthen the competitiveness of product in market.
Description of drawings
Accompanying drawing 1 is the main sketch map of the utility model;
Accompanying drawing 2 is back sketch mapes of accompanying drawing 1;
Accompanying drawing 3 is left sketch mapes of accompanying drawing 1;
Accompanying drawing 4 is perspective view of the utility model.
Among the figure: concave structure 1, length direction 2, plane 3, catch 4, catch 5, hole 6.
Embodiment
For further specifying the utility model, existing conjunction with figs. is set forth in detail:
Structure of the utility model and shape are shown in accompanying drawing 1, and global shape is the concave structure 1 of solid rectangle, and three of concave structure 2 extensions along its length is mutual vertically disposed plane 3.Two ends of concave structure are respectively arranged with and above-mentioned plane 3 vertically disposed catch 4; Be provided with in the middle of the concave structure equally and the 3 vertical settings of above-mentioned plane; And the catch 5 parallel with catch 4, catch is divided into two uniform concave structures with described insulation spacer overall structure.Be respectively arranged with penetrating hole 6 on the said catch, make between two concave structures, communicate between concave structure and the outside.
In use can earlier the concave structure 1 of putting into the utility model be closed in the whole utmost point assembly of lithium ion battery; Formation is to the insulation protection of utmost point group; Together put into battery case again; Can shell wall and utmost point group be isolated, realize the complete isolated insulation of whole utmost point group in battery case played necessary insulation protection and positioning action.Make battery under extreme service condition, operate as normal to use, thereby guarantee the fail safe that battery uses, effectively prevent the possibility of battery short circuit,
The PP material punching press injection moulding that concave structure 1 uses high anticorrosive, high temperature resistant, low temperature resistant, long-time use can not be out of shape contraction is processed, and cleaning surfaces does not have greasy dirt, and neatly smooth, edge does not have burr.
Claims (2)
1. a lithium-ion-power cell built-in electrical insulation Upper gasket structure is characterized in that the insulation spacer global shape is concave structure, and the part that concave structure extends along its length is the plane; Be respectively arranged with in two ends of concave structure and the spill thereof and the perpendicular catch in above-mentioned plane, this catch is divided into two concave structures with described insulation spacer integral body; Said catch is provided with penetrating hole, makes between two concave structures, communicates between concave structure and the outside.
2. lithium-ion-power cell built-in electrical insulation Upper gasket structure according to claim 1 is characterised in that described concave structure is a rectangle.
