Abstract
The utility model discloses a store formula lithium thionyl chloride cell actuating device, including outer tube (2), the one end of outer tube (2) links to each other with straight tube (8) through connecting (7), and the other end of outer tube (2) passes through screw (10) to be connected with base (1), is provided with inner tube (3) in outer tube (2), and the one end of inner tube (3) is connected through laser beam welding and base (1), and the other end links to each other with tubulose cutter (6), and tubulose cutter (6) one end is metal seal membrane (5), has between outer tube (2) and inner tube (3) air cavity (11). The utility model provides a problem of not corrosion -resistant, the blow -by of conventional reserve cell actuating device.
Description
Technical field
The utility model relates to stocks formula lithium thionyl chloride cell, particularly battery activated device.
Background technology
Stock formula lithium thionyl chloride cell by active device, the isolating metal film between liquid reservoir with dry battery to be communicated with, by external force, electrolyte to be entered in battery with electrode contact thus activated batteries.Owing to stocking lithium, the thionyl chloride chance water meeting vigorous reaction in formula lithium thionyl chloride cell, battery pile and electrolyte must carry out air-tightness isolation with the external world, cell stack case, liquid reservoir, active device need adopt all-sealed structure to design, and thionyl chloride electrolytic corrosion is extremely strong, available encapsulant only has stainless steel, nickel, glass, polytetrafluoroethylene.In addition, thionyl chloride is positive active material, can constantly consume in discharge process, if adding amount is not enough, electrical property not only can be caused to reduce, time serious, Local Dry district can be caused, cause cell safety problem, therefore, stock formula lithium thionyl chloride cell active device extremely important.For these reasons, activation and Sealing Technology that formula lithium thionyl chloride cell can not adopt conventional reserve cell is stocked.
Summary of the invention
The technical problems to be solved in the utility model is: provide one to stock formula lithium thionyl chloride cell active device, the problems such as conventional reserve cell active device is not corrosion-resistant to solve, blow-by.
In order to solve the problems of the technologies described above, the utility model takes following technical scheme: one stocks formula lithium thionyl chloride cell active device, comprise outer tube, one end of outer tube is connected with straight tube by joint, and the other end of outer tube is connected with base by screw, is provided with interior pipe in outer tube, one end of interior pipe is connected with base by Laser Welding, the other end is connected with Tubular tool, and Tubular tool one end is metal sealing film, has air cavity between outer tube and interior pipe.Described Tubular tool refers in a tubular form and the sharply sharp structural member in end.
Interior tube and tube shape cutter junction is provided with O RunddichtringO, is provided with O RunddichtringO between Tubular tool and outer tube.
Air cavity is communicated with gas generator.
Base, outer tube, interior pipe and Tubular tool all adopt stainless steel.
O RunddichtringO adopts fluorubber.
Relative to prior art, active device structural member of the present utility model all adopts stainless steel, and sealing O type circle adopts fluorubber material, and stainless steel can tolerate electrolytic corrosion, and fluorubber can tolerate electrolytic corrosion within the short time such as activation and operating time; Active device adopts gas generator as power source, access electro activation signal before activating, and gas generator provides source of the gas, in airtight cavity, form air pressure; Cutter pipe (Tubular tool) tracheae adopts unique " nested type " design, and (nested type refers to that Tubular tool is enclosed within outside interior pipe, insert again in outer tube), namely cutter pipe (Tubular tool) by O type snare on inner pipe, and assembling within the outer tube, form airtight air cavity between interior pipe and outer tube, under air pressure drives, make cutter pipe (Tubular tool) mobile, promote Tubular tool and pierce through barrier film, be somebody's turn to do " nested type " project organization compact, be conducive to miniaturization.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is Fig. 1 left view;
Fig. 3 is the partial enlarged drawing of Fig. 1.
Embodiment
Be described in further detail below in conjunction with accompanying drawing the utility model:
As shown in FIG. 1 to 3, stock formula lithium thionyl chloride cell active device primarily of compositions such as base 1, outer tube 2, interior pipe 3, O RunddichtringO 4, metal sealing film 5, Tubular tool 6, joint 7, straight tube 8, gas generator 9, screws 10, a gas generator 9 drives No. four cutter pipes (Tubular tool 6) simultaneously, interior pipe 3 is connected with base 1 by Laser Welding, Tubular tool 6 and corresponding O RunddichtringO 4 are loaded interior pipe 3, and overlap upper exterior tube 2, then by screw 10, outer tube 2 is connected with base 1, last installing gas generator 9.During activation, first access electro activation signal, gas generator 9 acts on and produces source of the gas, air pressure is formed in airtight cavity, promote Tubular tool 6 by air cavity 11 move and pierce through metal sealing film 5, make the pipeline connection between liquid reservoir and dry battery, electrolyte just can be made under external force to enter in battery with electrode contact thus activated batteries.
