却しなければならないと−う問題があった。According to the seal relay manufacturing method explained in the conventional example, 1
This is a problem with the sealing method that completely seals the relay with multiple sealing operations. There is a point where the bulging deformation of the relay housing caused by the heated air inside the sealed relay after high-temperature heating will no longer occur because the heated air is released to the outside from the secondary seal hole. It is necessary to inspect the characteristics after the manufacturing is completed (even if the characteristics are inspected and adjusted before sealing, ?1Fls will be applied during sealing, and the relay's characteristics will change due to the heating.
There is no point in testing the characteristics until after the final production is completed.)
After the relay has been sealed, the seal cannot be removed again, so the characteristics cannot be readjusted and the relay has to be discarded as a product with defective characteristics.
本発明は前記問題点に看目し改善を図ったものであって
