The thermal battery comprises a binding post, a battery cover and a battery body, wherein the binding post and the battery cover are integrally sintered by use of a glass insulator which is coated with a high temperature-resistant sealant, wherein the coating thickness is 0.5 to 1 millimeter. An insulating protective pad which is as large as the battery cover is arranged on the sealant; the insulating protective pad is 0.1+/-0.02 millimeters and is made of natural mica. The thermal battery is capable of achieving the effect that the insulation resistance between each circuit of the battery and a metal part of a housing and the insulation resistance between the circuits meet the use requirements in a severe storage environment.
Description
Technical field
The utility model relates to a kind of thermal cell, belongs to thermal cell technical field.
Background technology
Usually, be 15 DEG C～35 DEG C in temperature, under the condition that humidity is 20%～80%, between the metal position of the each loop of thermal cell and shell, between the each independent loop of thermal cell, insulation resistance should be not less than 50M Ω; Under other environmental condition, between the metal position of the each loop of thermal cell and shell, between the each independent loop of thermal cell, insulation resistance should be not less than 2M Ω.Thermal cell in the preparation, is all produced in relative humidity is less than 2% environment, and after element cell produces, 100% use helium mass analyzer is hunted leak, and requires leak rate to be not more than 0.3Pacm
3/ s.Therefore, the internal structure of thermal cell can not affect the insulation resistance of battery.As shown in Figure 1, between each loop of outside batteries and the metal position of shell and be to insulate by sintered glass insulator on battery cover between each independent loop, after glass sintering, require the insulation resistance between binding post (output loop) and battery cover to be greater than 400M Ω, meet the requirement of thermal cell to insulation resistance.But battery is in storage process, due to the impact of external environment condition, change at normal temperatures water and may cover above glass insulator as stored after battery or low tempertaure storage the frost of battery surface under at wet environment, cause the insulation resistance between the metal position of the each loop of battery and shell, between each independent loop to reduce, can not meet the requirement of thermal cell to insulation resistance, thereby affect the electrical property of thermal cell.Or in harsh mechanical environment; due to the vibration friction between output lead and metal battery cover; may there are the insulating protective layer wearing and tearing of wire; outside being exposed to, wire contacts with metal battery cover; cause insulation resistance between the metal position of cell circuit and shell to decline, can not meet the requirement of thermal cell to insulation resistance.
Summary of the invention
The utility model, in order to overcome prior art deficiency, provides a kind of thermal cell.
Technical solution of the present invention:
A kind of thermal cell; comprise binding post, battery cover and battery body; integral by glass insulator johning knot between described binding post and described battery cover, on described glass insulator, be coated with fluid sealant, on it, there is the insulating protection pad that a slice is identical with described battery cover size.
Described fluid sealant is NQ-704 silicon rubber.
The coating thickness of described fluid sealant is about 0.5mm～1mm.
Described insulation protection mat thickness is 0.1 ± 0.02mm.
Described insulating protection pad is natural mica material.
The utility model beneficial effect compared with prior art:
Be combined in and be integrally formed one deck insulating protective layer by fluid sealant and insulating protection pad, greatly improved the insulation resistance of thermal cell.The thermal cell that uses insulation protection, the insulation resistance under rugged environment condition between the metal position of the each loop of its battery and shell, between each independent loop is all greater than 100M Ω.Avoided in harsh mechanical environment the vibration friction between output lead and metal battery cover by insulation blocking simultaneously.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of thermal cell, comprise binding post 1, battery cover 3 and battery body 6, between described binding post 1 and described battery cover 3, be sintered into one by glass insulator 2, on described glass insulator 2, be coated with resistant to elevated temperatures fluid sealant 5, NQ-704 silicon rubber in the present embodiment, coating thickness is about 0.5mm～1mm.On fluid sealant 5, have the insulating protection pad 4 that a slice is identical with described battery cover 3 sizes, thickness is 0.1 ± 0.02mm, and material is natural mica.
Making the concrete operating procedure of thermal cell of the present utility model is:
First by battery cover surface alcohol swab wiped clean, then fluid sealant is coated on glass insulator uniformly, in the 3min after fluid sealant applies, insulating protection pad is placed up, after placement, press lightly insulating protection pad with hand, insulating protection pad and fluid sealant are bonded together; Finally thermal cell is at room temperature left standstill to 4h～12h, allow fluid sealant and insulating protection pad be solidified togather.
This thermal cell is carried out to insulation protection; then this kind of battery carried out respectively to low temperature-45 DEG C storage 6h test; temperature 40 is spent, the humid heat test of humidity 95%, time 96h; vibration level is the vibration test that 39.95g, time of vibration are 10min; after test, carry out the test of insulation resistance at 30min; measurement result is: the insulation resistance between the metal position of each loop and shell, between each independent loop is all greater than 100M Ω, is far superior to the requirement of thermal cell to insulation resistance.
Above-described embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only embodiment of the present utility model; and be not used in limit protection range of the present utility model; all within spirit of the present utility model and principle, any amendment of making, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
