Claims (1)
入してなる被覆発熱線１を、所定の金属外筒５内に収容
させると共に該金属外筒５の端面部に定着される金属蓋
６に粉末充填ロアを開設し、該充填ロアより、金属外筒
５の内周と被覆発熱線１との間の空隙部８に金属粉末を
充填させ、周側面要所に金属粉末の係入し得る高所１０
を穿設した金属栓９を前記充填ロアへ嵌挿してその上端
部周縁を充填ロアの口縁に密接させた状態において、加
熱により、被覆発熱線１と金属外筒５との間に金属粉末
の凝結して形成された伝熱媒体１１を介在させると共に
、前記高所１０内における金属粉末の凝結により金属栓
９の脱出を防止し得るよう構成した、密閉型電気発熱体
における金属粉末充填口の閉塞構造。A coated heating wire 1, which is formed by enclosing a heating wire 4 in a metal tube 2 via an electrical insulator 3, is accommodated in a predetermined metal outer cylinder 5, and a metal is fixed to the end face of the metal outer cylinder 5. A powder filling lower is provided in the lid 6, and the gap 8 between the inner periphery of the metal outer cylinder 5 and the coated heating wire 1 is filled with metal powder from the filling lower, and the metal powder is attached to key points on the circumferential side. 10 high places you can enter
When the metal stopper 9 with a perforated hole is inserted into the filling lower and its upper end periphery is brought into close contact with the mouth edge of the filling lower, metal powder is formed between the coated exothermic wire 1 and the metal outer cylinder 5 by heating. A metal powder filling port in a closed electric heating element is configured to have a heat transfer medium 11 formed by condensation of the metal powder interposed therebetween and to prevent the metal plug 9 from escaping due to the condensation of the metal powder in the high place 10. occlusion structure.
