The reliability and safety of entire battery system is rung, therefore the reliability promotion of its detection device has become inevitable requirement.
Test device of suppressing existing at present only can realize compression to battery and fixation by hold-down bolt, then also need
It will manually with sharp instrument, for inflating, the device be time-consuming and laborious, consistency is poor and is easy to puncture for trepanning on the shell of rectangular cell
Electric core membrane causes battery core internal short-circuit.The utility model test device reserves enough intrinsic silicon spaces and hold-down bolt length
Meet different size battery testing demand, and hold-down bolt internal openings and passes through spiral shell outside end face internal thread connection ventilation thimble
Line, the thimble that can be ventilated by adjusting are threaded into depth to control the testing requirement of different wall thickness battery, are compressing electricity in this way
Tap operation may be implemented while pond, wherein O-ring seal is pressed between battery side wall and hold-down bolt end face and plays gas
Sealing function is flowed, to improve the consistency of testing efficiency and test sample, reduce test sample fraction defective and realize and survey
The versatility that trial assembly is set.
Utility model content
The purpose of this utility model is to provide a kind of quadrate lithium battery and suppresses test device, and realization is compressed to battery
The device of tap operation can also be realized while fixed.
A kind of quadrate lithium battery suppresses test device, including ventilation thimble and the babinet for placing rectangular cell, described
Be threaded with hold-down bolt on one end side wall of babinet, the screw rod end of the hold-down bolt is located at cabinets cavity, and with ventilation
Thimble is connected through a screw thread；The sealing ring for being sealed with rectangular cell is arranged on the ventilation thimble.
The screw rod end of further scheme, the hold-down bolt offers bolt bore, and the bolt bore is equipped with internal thread；
The external screw thread to match with the internal thread of the bolt bore is offered on the end of the ventilation thimble；By adjusting ventilation top
Depth of the needle in hold-down bolt come control ventilation thimble length.
Further scheme offers the stomata to connect with the bolt bore inside the ventilation thimble.
Further scheme, the cavity volume of the babinet are more than the volume of rectangular cell.
This test device is not implemented only in and is fixed to battery, can also realize to battery tap operation；It is promoted
Testing efficiency, test accuracy and versatility, it is ensured that the battery of different size can quickly and accurately be completed to suppress test.
The volume of the cabinets cavity volume ratio rectangular cell of the present apparatus is big, so as to meet different size battery testing need
It asks.
The screw rod end of hold-down bolt is connected through a screw thread ventilation thimble in the present apparatus, the screw thread for the thimble that can be ventilated by adjusting
Depth is screwed into control the length of ventilation thimble, that is, adapts to the testing requirement of different wall thickness battery, it is made to compress battery
Simultaneously tap operation may be implemented, to improve testing efficiency and test sample consistency, reduce test sample fraction defective with
And realize the versatility of test device.
It determines that ventilation thimble is screwed into the depth in hold-down bolt according to the wall thickness of tested battery, makes to be located at outside clamping screw
Ventilation thimble length it is consistent with the thickness of shell of battery；Same batch battery only needs to adjust the length of primary ventilation thimble.
When trepanning, need to only screw hold-down bolt can make ventilation thimble be pierced into the purpose that battery case realizes trepanning.So the present apparatus saves
The consistency of Shi Shengli, trepanning are good, and the depth for being pierced into battery is controllable, will not puncture electric core membrane and cause battery core internal short-circuit.
When operation, first determines that ventilation thimble is screwed into the depth in hold-down bolt according to the wall thickness for being tested battery, make to be located at pressure
The length of ventilation thimble outside tight screw rod is consistent with the thickness of shell of battery；Then tested battery is installed on to the inner cavity of babinet
In, then hold-down bolt is tightened, so that the front end of ventilation thimble is resisted battery, sealing ring is pressed in the spiral shell of battery side wall and hold-down bolt
Between bolt end face, play the role of it is air current sealed, to improve testing efficiency and test sample consistency, reduce test sample
Fraction defective and the versatility for realizing test device.Hold-down bolt is further screwed, the front end of ventilation thimble is made to fully penetrate electricity
The side wall in pond；Outer gas stream is finally accessed, air-flow enters inside battery by hold-down bolt endoporus and ventilation thimble, to realize
Fixation, trepanning and sealing to battery；Battery is finally observed to air-tightness into the water and record the blowing pressure is completed to survey
Examination.
