一、整車線束是什么東西

整車線束是汽車電(dian)路(lu)的網絡(luo)主(zhu)體，沒有(you)線束也(ye)就不(bu)存在汽車電(dian)路(lu)。

線(xian)(xian)束是(shi)指(zhi)由銅材(cai)沖制(zhi)而(er)成的接(jie)觸件(jian)(jian)端子（連(lian)接(jie)器(qi)）與電線(xian)(xian)電纜壓接(jie)后(hou)，外面再塑(su)壓絕緣體或外加金屬殼體等(deng)，以(yi)線(xian)(xian)束捆扎形(xing)成連(lian)接(jie)電路的組件(jian)(jian)。

二、整車線束是用來干什么的

有人做了(le)一個(ge)形象比(bi)喻。如(ru)果把微(wei)機、傳感(gan)器(qi)、執(zhi)(zhi)行器(qi)的功能(neng)比(bi)作人體，那么(me)微(wei)機可以說相當于人的大腦，傳感(gan)器(qi)相當于感(gan)覺器(qi)官。執(zhi)(zhi)行器(qi)相當于運(yun)動(dong)機構。然后束是神(shen)經和血管。

整車線束作用是連接汽車的(de)電(dian)(dian)(dian)(dian)(dian)氣(qi)和電(dian)(dian)(dian)(dian)(dian)子元件。目前，無論是豪華車還是經濟型普通車，線束的(de)形式(shi)基本相同，由電(dian)(dian)(dian)(dian)(dian)線、插(cha)件、打包帶組成。必(bi)須保證電(dian)(dian)(dian)(dian)(dian)信號和連接電(dian)(dian)(dian)(dian)(dian)路的(de)可(ke)靠性，為電(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)氣(qi)元件提供規定的(de)電(dian)(dian)(dian)(dian)(dian)流值。防止對周圍電(dian)(dian)(dian)(dian)(dian)路產生電(dian)(dian)(dian)(dian)(dian)磁干(gan)擾，消除電(dian)(dian)(dian)(dian)(dian)氣(qi)短路。

整車線(xian)(xian)(xian)束(shu)在功能上是分開(kai)的(de)，有兩條(tiao)電(dian)源(yuan)(yuan)(yuan)線(xian)(xian)(xian)承(cheng)載驅動執行(xing)器(qi)（執行(xing)器(qi)）的(de)電(dian)源(yuan)(yuan)(yuan)，而信(xin)號線(xian)(xian)(xian)則(ze)傳(chuan)(chuan)輸傳(chuan)(chuan)感器(qi)輸入(ru)命(ming)令。電(dian)源(yuan)(yuan)(yuan)線(xian)(xian)(xian)是承(cheng)載大電(dian)流的(de)粗(cu)線(xian)(xian)(xian)，信(xin)號線(xian)(xian)(xian)是不(bu)承(cheng)載電(dian)力(li)的(de)細(xi)線(xian)(xian)(xian)（光纖通信(xin)）。例如信(xin)號回路中(zhong)使(shi)用的(de)導線(xian)(xian)(xian)截面積分別(bie)為0.3和(he)0.5平方毫米。
