需連(lian)接(jie)(jie)(jie)的導線種類和連(lian)接(jie)(jie)(jie)形式不同(tong)，其連(lian)接(jie)(jie)(jie)的方法(fa)也不同(tong)常用的連(lian)接(jie)(jie)(jie)方法(fa)有絞合連(lian)接(jie)(jie)(jie)緊壓連(lian)接(jie)(jie)(jie)焊接(jie)(jie)(jie)等連(lian)接(jie)(jie)(jie)前應小心地剝除(chu)導線連(lian)接(jie)(jie)(jie)部位的絕緣層，注意不可損傷其芯線。
絞合(he)連(lian)接(jie)(jie)是指將(jiang)需(xu)連(lian)接(jie)(jie)導線的(de)芯線直接(jie)(jie)緊密(mi)絞合(he)在一起銅導線常用絞合(he)連(lian)接(jie)(jie)。
單(dan)股銅(tong)導線(xian)(xian)的直接連(lian)接小截面單(dan)股銅(tong)導線(xian)(xian)連(lian)接方法如圖1所示，先將兩導線(xian)(xian)的芯線(xian)(xian)線(xian)(xian)頭(tou)作X形交叉，再將它們(men)相互纏繞2～3圈(quan)(quan)后扳(ban)直兩線(xian)(xian)頭(tou)，然后將每個線(xian)(xian)頭(tou)在另一(yi)芯線(xian)(xian)上緊貼密繞5～6圈(quan)(quan)后剪去多余線(xian)(xian)頭(tou)即可。

大截(jie)(jie)面單股銅導(dao)線(xian)(xian)(xian)(xian)(xian)連接(jie)方法如圖2所示，先在兩導(dao)線(xian)(xian)(xian)(xian)(xian)的(de)芯線(xian)(xian)(xian)(xian)(xian)重疊(die)處填入(ru)一(yi)根(gen)相同直徑(jing)的(de)芯線(xian)(xian)(xian)(xian)(xian)，再用一(yi)根(gen)截(jie)(jie)面約1.5mm2的(de)裸(luo)(luo)銅線(xian)(xian)(xian)(xian)(xian)在其上緊密纏(chan)繞(rao)(rao)，纏(chan)繞(rao)(rao)長度(du)為導(dao)線(xian)(xian)(xian)(xian)(xian)直徑(jing)的(de)10倍左(zuo)右，然后將被連接(jie)導(dao)線(xian)(xian)(xian)(xian)(xian)的(de)芯線(xian)(xian)(xian)(xian)(xian)線(xian)(xian)(xian)(xian)(xian)頭(tou)分別折回，再將兩端的(de)纏(chan)繞(rao)(rao)裸(luo)(luo)銅線(xian)(xian)(xian)(xian)(xian)繼(ji)續(xu)纏(chan)繞(rao)(rao)5～6圈(quan)后剪去多余(yu)線(xian)(xian)(xian)(xian)(xian)頭(tou)即可(ke)。

不同截(jie)面單股銅導線連接方法如圖3所示(shi)，先將細導線的芯線在粗導線的芯線上緊密纏繞(rao) 5～6圈，然后(hou)將粗導線芯線的線頭折回緊壓在纏繞(rao)層上，再(zai)用(yong)細導線芯線在其上繼續纏繞(rao)3～4圈后(hou)剪(jian)去(qu)多余線頭即可(ke)。

單股(gu)銅導線(xian)(xian)(xian)的分(fen)支連(lian)接單股(gu)銅導線(xian)(xian)(xian)的T字(zi)分(fen)支連(lian)接如(ru)圖4所示，將支路(lu)(lu)芯線(xian)(xian)(xian)的線(xian)(xian)(xian)頭(tou)(tou)緊(jin)密纏繞(rao)在(zai)干(gan)路(lu)(lu)芯線(xian)(xian)(xian)上5～8圈后剪(jian)去多余線(xian)(xian)(xian)頭(tou)(tou)即可(ke)對于較小截(jie)面的芯線(xian)(xian)(xian)，可(ke)先將支路(lu)(lu)芯線(xian)(xian)(xian)的線(xian)(xian)(xian)頭(tou)(tou)在(zai)干(gan)路(lu)(lu)芯線(xian)(xian)(xian)上打一(yi)個環繞(rao)結，再(zai)緊(jin)密纏繞(rao)5～8圈后剪(jian)去多余線(xian)(xian)(xian)頭(tou)(tou)即可(ke)。
