Description
Technical field
The invention belongs to thermal cell technical field, be specifically related to a kind of thermal cell insulated type lead set flow assembly method.
Background technology
Thermal cell is typically to be made up of element cell, electric interfaces and mechanical interface, and wherein element cell is that thermal cell produces
The core component of raw electric energy, its performance determines whether the output of battery meets technology requirement, and can decide thermal cell normal
Complete preplanned mission.Pile is again the core component of element cell, and pile is made up of multiple cell connection in series-parallel, and can pile
Normal output regulation electric energy is to determine the key that thermal cell the most normally works.Pile passes through the gold that on flow collection sheet, electric conductivity is good
Belonging to lead-in wire bar and externally transmit electric energy, the insulation protection of lead-in wire bar is related to the work that battery is the most normal, safe.
Thermal cell be the heating system with battery itself nonconducting solid state salt electrolyte add heat fusing in from
Subtype conductor and enter a kind of hot activation reserve cell of duty.Its internal electrolyte is by two or more nothing
The eutectic of machine salt composition, during room temperature, electrolyte is non-conductive solid；During use, molten salt electrolyte melts and conducts electricity, and swashs
Battery alive, exports electric energy.Therefore, thermal cell operationally its internal temperature is usually maintained in more than 400 DEG C, at this moment, and lead-in wire
The isolation protective material of bar requires at least to be in non-conductive state in 450 DEG C of environmental conditions of high temperature.By retrieving domestic and international patent
And document, do not find the relevant report of lead-in wire bar safeguard protection.
Bar is exposed causes cell to prevent lead-in wire the most generally to use polyimide insulative adhesive tape parcel lead-in wire bar
Between short circuit.Polyimide insulative adhesive tape life-time service temperature range is at-200 DEG C ~ 300 DEG C, although short-term job maximum temperature
Can reach 680 DEG C, therefore, after bar may cause work if thermal cell simply uses polyimide insulative adhesive tape protection lead-in wire
Between phase cell, short circuit, ultimately results in thermal cell and there is potential safety hazard, therefore have battery use compress after battery pile
Installing mica strip the method wrapping up asbestos on lead-in wire bar, the method is suitable for the battery that pile is relatively large in diameter, the bar that goes between is few.But
Volume is progressively moved towards less along with missile weapon system, the most portable, to thermal cell product used in missile weapon system also
Have higher requirement, it is desirable to thermal cell output of products is more powerful, volume is less, weight is lighter.Thermal cell is straight at present
Footpath only has Φ 28mm, and wherein core part cell diameter only has Φ 22mm, and pile three tunnel exports, and has at five and goes between
Bar, removes battery container wall thickness and pile insulation protection layer thickness, and the thickness leaving often place's lead-in wire bar protection for is only 1mm, space
Less, be not suitable for assembling mica strip and asbestos sliver after compressing battery pile, therefore the insulated type of thermal cell output electric energy drawn
The assembling structure of line flow collection sheet proposes requirements at the higher level, on the premise of guaranteeing reliable in quality, improves assembling structure, improves work
Efficiency.

It is shorter than the length of the drainage strip of protection.
Further, when fixing mica strip with polyimide insulative adhesive tape, mica strip flushes with flow collection sheet edge, adhesive tape and cloud
Master bar is with width, length 10mm, each viscous 5mm on flow collection sheet and mica strip.
Further, described asbestos sliver uses 905/2 type thermal cell asbestos paper, width and mica strip with wide, to be shorter in length than
Mica strip；Before using, first by described asbestos sliver calcination half an hour under 500 DEG C of high temperature.
Further, during with polyimide insulative adhesive tape parcel asbestos sliver, asbestos sliver also should flush with flow collection sheet edge.
The thermal cell insulated type lead set flow that the present invention provides can preparation before pile assembling, will prepare during use
The lead-in wire bar of insulated type lead set flow is folded up, and has asbestos sliver one side near pile, convenient and swift.Polyimide insulative
Adhesive tape is ground floor protection, and asbestos sliver is second layer protection, and mica strip is third layer protection, prevents in pile between cell
It is short-circuited.
