接線端子的塑膠絕緣層材料和導電性構件立即關聯到接線端子的品質，他們各自決策了接線端子的介電強度能和導電率能。一切一個接線端子無效都將造成 全部自動化控制的不成功。這些方面世界各國產生的血的教訓是十分刻骨銘心的。防止是目地，剖析是基本。從某種程度上講，防止無效比剖析無效更關鍵。它對確保接線端子的品質和可靠性具備更實際的實際意義.　　接線端子從應用視角講，應當做到的作用是：接觸位置該通斷的地區務必通斷，接觸可靠。絕緣層位置不應該通斷的地區務必絕緣層可靠。接線端子普遍的致命性常見故障方式有下列三種：1.接觸欠佳　　接線端子內部的金屬材料電導體是接線端子的關鍵零件，它將來源于外界電纜線或電纜線的工作電壓，電流量或數據信號傳送到兩者之間般配的射頻連接器相(xiang)(xiang)匹配(pei)的(de)(de)(de)(de)(de)(de)(de)(de)接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)上。故(gu)(gu)接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)務(wu)必(bi)具(ju)有(you)(you)(you)優(you)質(zhi)(zhi)的(de)(de)(de)(de)(de)(de)(de)(de)構造，平穩(wen)可靠的(de)(de)(de)(de)(de)(de)(de)(de)接(jie)(jie)(jie)觸(chu)維持力和優(you)良的(de)(de)(de)(de)(de)(de)(de)(de)導(dao)電(dian)(dian)率能(neng)。因為(wei)接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)總體設計(ji)不(bu)(bu)(bu)科(ke)學(xue)，原(yuan)材(cai)(cai)料(liao)(liao)采用不(bu)(bu)(bu)正(zheng)確，模貝不(bu)(bu)(bu)穩(wen)定(ding)(ding)(ding)，生(sheng)(sheng)產加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)規(gui)格(ge)偏(pian)差，表(biao)(biao)面不(bu)(bu)(bu)光(guang)滑(hua)，熱處(chu)理(li)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)電(dian)(dian)鍍工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)等(deng)表(biao)(biao)面工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)處(chu)理(li)不(bu)(bu)(bu)科(ke)學(xue)，拼裝(zhuang)不(bu)(bu)(bu)善，存儲應用艱苦環境和實(shi)際操作(zuo)錯誤操作(zuo)，都(dou)是會在接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)的(de)(de)(de)(de)(de)(de)(de)(de)接(jie)(jie)(jie)觸(chu)位(wei)置和相(xiang)(xiang)互(hu)配(pei)合(he)(he)位(wei)置導(dao)致(zhi)(zhi)接(jie)(jie)(jie)觸(chu)欠佳(jia)(jia)。2.絕(jue)緣(yuan)(yuan)(yuan)層(ceng)(ceng)欠佳(jia)(jia)　　絕(jue)緣(yuan)(yuan)(yuan)體的(de)(de)(de)(de)(de)(de)(de)(de)功效是使接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)維持恰當的(de)(de)(de)(de)(de)(de)(de)(de)部位(wei)排序，并使接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)與(yu)接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)中間(jian)，接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)與(yu)罩殼中間(jian)互(hu)相(xiang)(xiang)絕(jue)緣(yuan)(yuan)(yuan)層(ceng)(ceng)。故(gu)(gu)絕(jue)緣(yuan)(yuan)(yuan)層(ceng)(ceng)件(jian)(jian)(jian)務(wu)必(bi)具(ju)有(you)(you)(you)優(you)質(zhi)(zhi)的(de)(de)(de)(de)(de)(de)(de)(de)電(dian)(dian)氣(qi)設備特性，物(wu)理(li)性能(neng)和加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)成(cheng)(cheng)形特性。尤其是伴(ban)隨(sui)著(zhu)密(mi)度(du)高(gao)的(de)(de)(de)(de)(de)(de)(de)(de)，微(wei)型化接(jie)(jie)(jie)線端子的(de)(de)(de)(de)(de)(de)(de)(de)普遍應用，絕(jue)緣(yuan)(yuan)(yuan)體的(de)(de)(de)(de)(de)(de)(de)(de)合(he)(he)理(li)壁厚愈(yu)來愈(yu)薄。這對絕(jue)緣(yuan)(yuan)(yuan)層(ceng)(ceng)材(cai)(cai)料(liao)(liao)，塑(su)料(liao)(liao)模具(ju)精(jing)密(mi)度(du)和成(cheng)(cheng)形加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)等(deng)明(ming)確提出了更苛嚴的(de)(de)(de)(de)(de)(de)(de)(de)規(gui)定(ding)(ding)(ding)。因為(wei)絕(jue)緣(yuan)(yuan)(yuan)體表(biao)(biao)面或(huo)內(nei)部存有(you)(you)(you)金屬材(cai)(cai)料(liao)(liao)不(bu)(bu)(bu)必(bi)要(yao)物(wu)，表(biao)(biao)面浮(fu)塵，助焊劑等(deng)環境污染(ran)返(fan)潮，有(you)(you)(you)機材(cai)(cai)料(liao)(liao)進(jin)行(xing)析出物(wu)及有(you)(you)(you)害物(wu)質(zhi)(zhi)吸咐膜與(yu)表(biao)(biao)面收縮水(shui)結合(he)(he)產生(sheng)(sheng)正(zheng)離子性導(dao)電(dian)(dian)性安(an)全(quan)通(tong)道，受潮，發霉，絕(jue)緣(yuan)(yuan)(yuan)層(ceng)(ceng)材(cai)(cai)料(liao)(liao)脆(cui)化等(deng)緣(yuan)(yuan)(yuan)故(gu)(gu)，都(dou)是會導(dao)致(zhi)(zhi)短路(lu)故(gu)(gu)障(zhang)(zhang)，走電(dian)(dian)，穿透，接(jie)(jie)(jie)地電(dian)(dian)阻(zu)劣等(deng)絕(jue)緣(yuan)(yuan)(yuan)層(ceng)(ceng)安(an)全(quan)隱(yin)患。3.固定(ding)(ding)(ding)不(bu)(bu)(bu)動(dong)欠佳(jia)(jia)　　絕(jue)緣(yuan)(yuan)(yuan)體不(bu)(bu)(bu)但起(qi)絕(jue)緣(yuan)(yuan)(yuan)層(ceng)(ceng)功效，一(yi)般(ban)也為(wei)外伸的(de)(de)(de)(de)(de)(de)(de)(de)接(jie)(jie)(jie)觸(chu)件(jian)(jian)(jian)出示精(jing)準的(de)(de)(de)(de)(de)(de)(de)(de)對中合(he)(he)維護，另外還具(ju)備安(an)裝(zhuang)精(jing)準定(ding)(ding)(ding)位(wei)，卡緊固定(ding)(ding)(ding)不(bu)(bu)(bu)動(dong)在機器設備上的(de)(de)(de)(de)(de)(de)(de)(de)作(zuo)用。固定(ding)(ding)(ding)不(bu)(bu)(bu)動(dong)欠佳(jia)(jia)，輕(qing)則危害接(jie)(jie)(jie)觸(chu)可靠導(dao)致(zhi)(zhi)一(yi)瞬間(jian)關閉電(dian)(dian)源，比(bi)較嚴重(zhong)的(de)(de)(de)(de)(de)(de)(de)(de)便是商品(pin)(pin)瓦解(jie)。瓦解(jie)就是指接(jie)(jie)(jie)線端子在插(cha)合(he)(he)情況下，因為(wei)原(yuan)材(cai)(cai)料(liao)(liao)，設計(ji)方案(an)，加(jia)工(gong)(gong)(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)(gong)(gong)藝(yi)(yi)等(deng)緣(yuan)(yuan)(yuan)故(gu)(gu)造成(cheng)(cheng)
