考えられる。From the test results, no leakage was observed in the battery A using the PPS insulating packing of the present invention.
This is because the PPS resin of the present invention has a glass transition point of 90.
Because the temperature is in ° C, the rigidity does not change in the temperature range of -30 ° C to + 70 ° C, it can sufficiently withstand the compressive force caused by tightening the nut, and the sealing property between the terminal and nut and the cover plate can be maintained. It can be seen that it can be used in a wide temperature range. On the other hand, the battery B using the conventional insulating packing made of polypropylene resin leaked 60%. This is because the glass transition point of polypropylene resin is −10 ° C., and at −10 ° C. or lower, the rigidity of the resin changes and cannot withstand the compressive force of the nut. It is considered that the sex was not maintained.

From this, it can be seen that the packing sufficiently withstands the compressive force caused by the tightening of the nut (7), maintains the sealing properties between the terminal and the nut and the cover plate even when vibration is applied, and is excellent in earthquake resistance. . On the other hand, in the battery B using the conventional polypropylene resin insulating packing, 50% of the liquid leakage occurred.
From this, it is understood that the sealing property of the insulating packing of the polypropylene resin is not one that can withstand vibration.
