電吹風是(shi)常用(yong)(yong)(yong)的小(xiao)家電，由于(yu)電熱(re)絲發熱(re)功率大，發熱(re)集中(zhong)，其連接(jie)部分(fen)很容易松(song)動(dong)。常見的連接(jie)方法(fa)是(shi)用(yong)(yong)(yong)黃(huang)(huang)銅鉚(liu)釘將電熱(re)絲等導(dao)線鉚(liu)緊在(zai)云母板(ban)上。黃(huang)(huang)銅、鎳鉻(ge)絲、銅導(dao)線三者(zhe)的熱(re)膨脹(zhang)(zhang)系數(shu)不(bu)同，使用(yong)(yong)(yong)一段(duan)時間后(hou)鉚(liu)接(jie)點就(jiu)會松(song)動(dong)，導(dao)致(zhi)接(jie)觸(chu)不(bu)良甚至打火。找一根醫用(yong)(yong)(yong)１０號以上的不(bu)銹(xiu)鋼注射(she)針頭，切(qie)取5～10ｍｍ長的一小(xiao)段(duan)，穿(chuan)卡在(zai)原來的黃(huang)(huang)銅鉚(liu)釘孔(kong)中(zhong)作(zuo)支(zhi)點。因為(wei)紫銅的熱(re)脹(zhang)(zhang)系數(shu)比(bi)不(bu)銹(xiu)鋼大，當(dang)溫度升高后(hou)不(bu)但不(bu)會松(song)動(dong)，反而會接(jie)觸(chu)得更緊，筆者(zhe)用(yong)(yong)(yong)此法(fa)修理(li)過多種電熱(re)器件(jian)都很成功，長時間使用(yong)(yong)(yong)導(dao)電都十分(fen)良好。
