Description
Technical field
The invention belongs to thermal cell technical fields, and in particular to a kind of thermal cell insulated type lead flow collection sheet assembly method.
Background technique
Thermal cell is usually to be made of element cell, electric interfaces and mechanical interface, and wherein element cell is that thermal cell produces
The core component of raw electric energy, performance determine whether the output of battery meets technical requirements, decide that can thermal cell normal
Complete preplanned mission.Pile is the core component of element cell again, and pile is made of in series and parallel multiple single batteries, and can pile
Normal output regulation electric energy is the key that determine whether thermal cell works normally.Pile passes through gold with good conductivity on flow collection sheet
Belong to lead item and externally transmit electric energy, the insulation protection of lead item is related to whether battery normal, work of safety.
Thermal cell be with the heating system of battery itself nonconducting solid state salt electrolyte heating melting be in from
A kind of hot activation reserve cell of subtype conductor and entrance working condition.Its internal electrolyte is the nothing by two or more
The eutectic of machine salt composition, when room temperature, electrolyte is non-conductive solid；In use, molten salt electrolyte melts and conduction, swash
Battery living, exports electric energy.Therefore, its internal temperature is usually maintained in 400 DEG C or more, at this moment, lead to thermal cell at work
The isolation protective material of item 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, the relevant report of lead safeguard protection is not found.
At home usually using polyimide insulative adhesive tape package lead item to prevent lead item is exposed from causing single battery
Between short circuit.Polyimide insulative adhesive tape long-term use temperature range is at -200 DEG C ~ 300 DEG C, although short-term job maximum temperature
Can reach 680 DEG C, therefore, if thermal cell be only used only polyimide insulative adhesive tape protection lead item may cause work after
Short-circuit between phase single battery, eventually leading to thermal cell, there are security risks, therefore have battery to exist later using compression battery pile
The method installed mica strip on lead item and wrap up asbestos, this method are suitble to the battery that pile is relatively large in diameter, lead item is few.But
It is more portable as gradually to move towards volume smaller for missile weapon system, to thermal cell product used in missile weapon system
More stringent requirements are proposed, it is desirable that thermal cell output of products is more powerful, volume is smaller, weight is lighter etc..Thermal cell is straight at present
Diameter only has Φ 28mm, and wherein core part-single battery diameter only has Φ 22mm, and the output of three tunnel of pile shares lead at five
Item removes battery case wall thickness and pile insulating protective layer thickness, and the thickness for leaving every place's lead item protection for is only 1mm, space
It is smaller, be not suitable for assembling mica strip and asbestos sliver after compressing battery pile, therefore draw the insulated type of thermal cell output electric energy
The assembling structure of line flow collection sheet proposes requirements at the higher level, under the premise of ensuring reliable in quality, improves assembling structure, improves work
Efficiency.
Summary of the invention
Problems solved by the invention is that the prior art lacks the insulation protection to low profile thermal battery-use lead item；To solve
Described problem, the present invention provide a kind of thermal cell insulated type lead flow collection sheet assembly method.
Thermal cell insulated type lead flow collection sheet assembly method provided by the invention, comprising: Step 1: preparation band lead afflux
Two lead items are respectively symmetrically put and are welded in flow collection sheet two sides by piece；Step 2: selection mica strip, with polyimide insulative adhesive tape
Two panels mica strip is separately fixed at band lead flow collection sheet two sides；Step 3: overlayed on the mica strip of side with an asbestos sliver again,
It is wrapped up with polyimide insulative adhesive tape.
Further, lead item and flow collection sheet overlapping length about 8mm, it is totally eight two rows of that solder joint is symmetrically uniformly distributed.
Further, the material of the mica strip is natural mica, and long-term safety operating temperature is 600 DEG C, proof voltage 2KV
In the case where without breakdown, insulation resistance is greater than 2 × 109Ω (normality).
Further, the mica strip is rectangular parallelepiped structure, 2mm wider than lead item, with a thickness of 0.07mm ~ 0.09mm, length
The length for the drainage strip shorter than protected.
Further, when fixing mica strip with polyimide insulative adhesive tape, mica strip is flushed with flow collection sheet edge, adhesive tape and cloud
Master bar is same wide, length 10mm, each viscous 5mm on flow collection sheet and mica strip.
Further, the asbestos sliver uses 905/2 type thermal cell asbestos paper, width and mica strip with width, is shorter in length than
Mica strip；Before use, first by the asbestos sliver under 500 DEG C of high temperature calcination half an hour.
Further, when wrapping up asbestos sliver with polyimide insulative adhesive tape, asbestos sliver should also be flushed with flow collection sheet edge.
Thermal cell insulated type lead flow collection sheet provided by the invention can before pile assembles preparation, will prepare when use
The lead item of insulated type lead flow collection sheet is folded up, and has asbestos sliver one side close to pile, convenient and efficient.Polyimide insulative
Adhesive tape is first layer protection, and asbestos sliver is second layer protection, and mica strip is third layer protection, is prevented in pile between single battery
Short circuit occurs.
