电路图符号大全

电(dian)(dian)路图(tu)主要由元(yuan)(yuan)件(jian)(jian)(jian)符号(hao)、连线、结点、注释(shi)四大部分组(zu)成。元(yuan)(yuan)件(jian)(jian)(jian)符号(hao)表(biao)示(shi)实(shi)(shi)际电(dian)(dian)路中(zhong)(zhong)的(de)(de)(de)(de)元(yuan)(yuan)件(jian)(jian)(jian)，它的(de)(de)(de)(de)形(xing)(xing)状(zhuang)(zhuang)与实(shi)(shi)际的(de)(de)(de)(de)元(yuan)(yuan)件(jian)(jian)(jian)不一(yi)(yi)(yi)定相(xiang)(xiang)似，甚(shen)至完全不一(yi)(yi)(yi)样(yang)。但(dan)是(shi)它一(yi)(yi)(yi)般(ban)都(dou)表(biao)示(shi)出了元(yuan)(yuan)件(jian)(jian)(jian)的(de)(de)(de)(de)特(te)点，而且引脚的(de)(de)(de)(de)数(shu)目都(dou)和(he)(he)实(shi)(shi)际元(yuan)(yuan)件(jian)(jian)(jian)保持一(yi)(yi)(yi)致。连线表(biao)示(shi)的(de)(de)(de)(de)是(shi)实(shi)(shi)际电(dian)(dian)路中(zhong)(zhong)的(de)(de)(de)(de)导(dao)(dao)线，在(zai)(zai)(zai)(zai)原(yuan)理图(tu)中(zhong)(zhong)虽然是(shi)一(yi)(yi)(yi)根线，但(dan)在(zai)(zai)(zai)(zai)常用(yong)的(de)(de)(de)(de)印刷电(dian)(dian)路板中(zhong)(zhong)往(wang)往(wang)不是(shi)线而是(shi)各(ge)(ge)种形(xing)(xing)状(zhuang)(zhuang)的(de)(de)(de)(de)铜(tong)箔块，就(jiu)(jiu)像收(shou)音机原(yuan)理图(tu)中(zhong)(zhong)的(de)(de)(de)(de)许(xu)多连线在(zai)(zai)(zai)(zai)印刷电(dian)(dian)路板图(tu)中(zhong)(zhong)并(bing)不一(yi)(yi)(yi)定都(dou)是(shi)线形(xing)(xing)的(de)(de)(de)(de)，也可(ke)以(yi)是(shi)一(yi)(yi)(yi)定形(xing)(xing)状(zhuang)(zhuang)的(de)(de)(de)(de)铜(tong)膜(mo)。结点表(biao)示(shi)几个(ge)元(yuan)(yuan)件(jian)(jian)(jian)引脚或(huo)几条导(dao)(dao)线之间相(xiang)(xiang)互(hu)的(de)(de)(de)(de)连接(jie)关系。所(suo)有和(he)(he)结点相(xiang)(xiang)连的(de)(de)(de)(de)元(yuan)(yuan)件(jian)(jian)(jian)引脚、导(dao)(dao)线，不论数(shu)目多少(shao)，都(dou)是(shi)导(dao)(dao)通(tong)的(de)(de)(de)(de)。注释(shi)在(zai)(zai)(zai)(zai)电(dian)(dian)路图(tu)中(zhong)(zhong)是(shi)十分重(zhong)要的(de)(de)(de)(de)，电(dian)(dian)路图(tu)中(zhong)(zhong)所(suo)有的(de)(de)(de)(de)文(wen)字(zi)都(dou)可(ke)以(yi)归入注释(shi)—类。细看以(yi)上(shang)各(ge)(ge)图(tu)就(jiu)(jiu)会发现(xian)，在(zai)(zai)(zai)(zai)电(dian)(dian)路图(tu)的(de)(de)(de)(de)各(ge)(ge)个(ge)地方都(dou)有注释(shi)存(cun)在(zai)(zai)(zai)(zai)，它们被用(yong)来(lai)说(shuo)明元(yuan)(yuan)件(jian)(jian)(jian)的(de)(de)(de)(de)型号(hao)、名(ming)称等等。

电(dian)(dian)子设备中(zhong)有(you)各(ge)(ge)种(zhong)(zhong)(zhong)各(ge)(ge)样的(de)(de)图(tu)(tu)。能(neng)够说(shuo)明(ming)它(ta)(ta)(ta)们(men)工(gong)作(zuo)原理的(de)(de)是(shi)电(dian)(dian)原理图(tu)(tu)，简(jian)称(cheng)电(dian)(dian)路(lu)(lu)(lu)(lu)图(tu)(tu)。电(dian)(dian)路(lu)(lu)(lu)(lu)图(tu)(tu)有(you)两种(zhong)(zhong)(zhong)，一(yi)种(zhong)(zhong)(zhong)是(shi)说(shuo)明(ming)模(mo)(mo)拟电(dian)(dian)子电(dian)(dian)路(lu)(lu)(lu)(lu)工(gong)作(zuo)原理的(de)(de)。它(ta)(ta)(ta)用(yong)(yong)各(ge)(ge)种(zhong)(zhong)(zhong)图(tu)(tu)形符(fu)号表示电(dian)(dian)阻器(qi)(qi)、电(dian)(dian)容器(qi)(qi)、开关(guan)、晶体管等实物，用(yong)(yong)线条把(ba)(ba)元(yuan)(yuan)器(qi)(qi)件和单(dan)元(yuan)(yuan)电(dian)(dian)路(lu)(lu)(lu)(lu)按工(gong)作(zuo)原理的(de)(de)关(guan)系(xi)(xi)连(lian)接(jie)起来(lai)(lai)。这种(zhong)(zhong)(zhong)图(tu)(tu)长期(qi)以来(lai)(lai)就一(yi)直被叫做电(dian)(dian)路(lu)(lu)(lu)(lu)图(tu)(tu)。另一(yi)种(zhong)(zhong)(zhong)是(shi)说(shuo)明(ming)数(shu)字电(dian)(dian)子电(dian)(dian)路(lu)(lu)(lu)(lu)工(gong)作(zuo)原理的(de)(de)。它(ta)(ta)(ta)用(yong)(yong)各(ge)(ge)种(zhong)(zhong)(zhong)图(tu)(tu)形符(fu)号表示门、触发器(qi)(qi)和各(ge)(ge)种(zhong)(zhong)(zhong)逻(luo)(luo)辑(ji)部(bu)(bu)件，用(yong)(yong)线条把(ba)(ba)它(ta)(ta)(ta)们(men)按逻(luo)(luo)辑(ji)关(guan)系(xi)(xi)连(lian)接(jie)起来(lai)(lai)，它(ta)(ta)(ta)是(shi)用(yong)(yong)来(lai)(lai)说(shuo)明(ming)各(ge)(ge)个(ge)逻(luo)(luo)辑(ji)单(dan)元(yuan)(yuan)之间的(de)(de)逻(luo)(luo)辑(ji)关(guan)系(xi)(xi)和整机(ji)(ji)的(de)(de)逻(luo)(luo)辑(ji)功能(neng)的(de)(de)。为(wei)了(le)和模(mo)(mo)拟电(dian)(dian)路(lu)(lu)(lu)(lu)的(de)(de)电(dian)(dian)路(lu)(lu)(lu)(lu)图(tu)(tu)区别开来(lai)(lai)，就把(ba)(ba)这种(zhong)(zhong)(zhong)图(tu)(tu)叫做逻(luo)(luo)辑(ji)电(dian)(dian)路(lu)(lu)(lu)(lu)图(tu)(tu)，简(jian)称(cheng)逻(luo)(luo)辑(ji)图(tu)(tu)。除了(le)这两种(zhong)(zhong)(zhong)图(tu)(tu)外，常用(yong)(yong)的(de)(de)还(hai)有(you)方框图(tu)(tu)。它(ta)(ta)(ta)用(yong)(yong)一(yi)个(ge)框表示电(dian)(dian)路(lu)(lu)(lu)(lu)的(de)(de)一(yi)部(bu)(bu)分，它(ta)(ta)(ta)能(neng)简(jian)洁明(ming)了(le)地说(shuo)明(ming)电(dian)(dian)路(lu)(lu)(lu)(lu)各(ge)(ge)部(bu)(bu)分的(de)(de)关(guan)系(xi)(xi)和整机(ji)(ji)的(de)(de)工(gong)作(zuo)原理。
