PCB接線端子作為射頻連接器的一種，是電氣設備制造行業中的一個關鍵部件，起著不能取代、不容忽視的功效，因工程項目專業技術人員在維修時最 先也是以插口查驗，也就是說接線端子下手，因而接線端子排的設計方(fang)案(an)至(zhi)關重要。

商品的設計方案是集于：產品執行標準、原材料、構造、電鍍工藝、驗證(zheng)、磨具、及生產制(zhi)造加(jia)工工藝的一種綜合型設計方案(an)，接線端(duan)子也(ye)是如此。

（一）產品執行標準起著總體指導方針，基本上全部的考慮到都以它為根據，人們插拔式接線端子型號設(she)計規(gui)范最 先以UL和CSA為(wei)標準，但是在(zai)一些電氣設(she)備主要參數層(ceng)面還可以以別的規(gui)范為(wei)根(gen)據，如高低溫試(shi)驗。
