Abstract
The utility model relates to a high-reliability power supply thermal battery which comprises a battery shell, a battery cover and an ignition head, wherein an ignition fire circuit fixed outside an electric pile is arranged in the battery shell, and the battery cover is welded with the binding post of an external circuit; and the high-reliability power supply thermal battery is characterized in that the ignition head is positioned at the bottom of the battery shell and is connected with the binding post into a whole through a lead; and a fire circuit isolation pad is arranged between the ignition fire circuit in the shell and the battery cover. Because the ignition head is arranged at the bottom of the battery, the distance between the ignition position of the ignition head and the binding post on the battery cover is increased, and the fire circuit isolation pad is additionally arranged between the ignition fire circuit in the shell and the battery cover, so that thermal shock generated by the binding post on the battery cover in the ignition fire circuit is effectively prevented, the binding post is prevented from desoldering with the external circuit due to thermal shock, and the normal operation of the thermal battery is guaranteed; and moreover, by adopting a thermal insulation pad of the battery cover, heat transfer to a battery cover body in the process of operating the battery is reduced, the temperature rise of the binding post is delayed, and the normal operation of the thermal battery is ensured.
Description
Technical field
The utility model belongs to the thermal cell technical field, particularly relates to a kind of highly reliable power supply thermal cell.
Background technology
Thermal cell is to become ionic conductor to nonconducting solid-state salt electrolyte heating and melting and the nonrecoverable reserve cell of self entering operating state with heating component own.
Present known thermal cell is the upper end igniting, and promptly igniter head is arranged at the battery top, is fixed on the battery lid.After this structure thermal cell applied activation signal, igniter head momentary action produced great amount of heat; The thermal shock that fiery road produces of in addition igniting causes that the binding post temperature raises rapidly on the battery cover; Through test; The binding post temperature raises and can reach more than 30 ℃ behind the 20s; The binding post temperature raises more than 100 ℃ behind the 2min, later stage even cause binding post because of thermal shock causes melts soldering tin and external circuit sealing-off, causes the thermal cell can not normal power supply.
Summary of the invention
The utility model provides a kind of binding post of avoiding because of thermal shock and external circuit sealing-off for solving the technical problem that exists in the known technology, guarantees the highly reliable power supply thermal cell of thermal cell operate as normal.
The technical scheme that the utility model is taked is:
A kind of highly reliable power supply thermal cell comprises battery case, battery cover and igniter head; The fiery road of igniting that is fixed on the pile outside is arranged in the battery case; Be fixed with the binding post that welds external circuit through insulator on the battery cover, be characterized in: said igniter head is positioned at the battery case inner bottom part, and is connected as a single entity through lead-in wire and binding post; Ignite in the housing and be equipped with fiery road isolating pad between fiery road and the battery cover.
The said fiery road of igniting is that zirconium powder adds the medicine of a warm nature.
Battery cover above the isolating pad of said fiery road simultaneously is pasted with the battery cover heat keeper.
Said fiery road isolating pad and battery cover heat keeper are asbestos.
Said insulator is a glass material.
Advantage and the good effect that the utlity model has are:
1, the utility model is owing to place battery bottom with igniter head; Increased the distance of binding post on igniter head armed position and the battery cover; In housing, ignite in addition and be equipped with fiery road isolating pad between fiery road and the battery cover; Effectively blocked the fiery road of igniting to the thermal shock that binding post on the battery cover produces, avoided binding post, guaranteed the operate as normal of thermal cell because of thermal shock and external circuit sealing-off.
2, the utility model has been owing to adopted the battery cover heat keeper, reduced in the battery operated process to the heat transmission of battery lid, delayed the rising of binding post temperature, guarantees that further binding post because of overheated that cause and external circuit sealing-off, guarantees the thermal cell operate as normal.

Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
A kind of highly reliable power supply thermal cell comprises battery case, battery cover and igniter head; The fiery road of igniting that is fixed on the pile outside is arranged in the battery case; Be fixed with the binding post that welds external circuit through insulator on the battery cover.
The innovative point of the utility model is:
Said igniter head is positioned at the battery case inner bottom part, and is connected as a single entity through lead-in wire and binding post; Ignite in the housing and be equipped with fiery road isolating pad between fiery road and the battery cover; The said fiery road of igniting is that zirconium powder adds the medicine of a warm nature; Battery cover above the isolating pad of said fiery road simultaneously is pasted with the battery cover heat keeper; Said fiery road isolating pad and battery cover heat keeper are asbestos; Said insulator is a glass material.
All paste one deck asbestos as insulation material at stainless steel battery case 2 inner bottom parts and inwall; Paste one deck asbestos pad identical as battery cover heat keeper 7 in the one side of stainless steel battery cover 8, be fixed with glass insulator 9 on the battery cover on the hole wall of link post 10 with the internal surface of battery shell diameter; Select for use nickel strap as lead-in wire 5, an end tie point duration and degree of heating 1 of lead-in wire, the other end of lead-in wire connect binding post, the acting as through soldering welding external circuit of said binding post.Igniter head is placed the bottom in the battery case, paste the zirconium powder of one deck around the pile 4, be placed in the battery case then as the fiery road 3 of igniting; Select for use flexible asbestos material as fiery road isolating pad 6, fiery road isolating pad is filled up the pile top that is pasted with zirconium powder, the diameter of fiery road isolating pad is greater than the diameter of pile.Said fiery road isolating pad is equivalent to " stopper ", plays the fiery road burned flame of igniting is stoped the effect below the isolating pad of fiery road, prevents that flare from scurrying to battery cover.Battery cover is pasted one of asbestos pad face down, binding post passes hole and the sealing and fixing of battery cover on battery cover, at last battery cover seal weld is connected on the battery case oral area, processes highly reliable power supply thermal cell.
After the highly reliable power supply thermal cell of the utility model activated 20s, the binding post temperature raise and is no more than 2 ℃; After activating 2min, temperature raises and is no more than 10 ℃, and omnidistance temperature raises and is no more than 30 ℃, has guaranteed the high reliability power supply of thermal cell.
