在選擇矩形電連接器時，有多個關鍵因(yin)素需要考慮。先是電(dian)(dian)氣性(xing)能，包括額定(ding)電(dian)(dian)壓、額定(ding)電(dian)(dian)流和接(jie)觸電(dian)(dian)阻(zu)等。額定(ding)電(dian)(dian)壓和電(dian)(dian)流決定(ding)了連接(jie)器能夠安全承載的電(dian)(dian)能大小，如果選擇不當(dang)，可(ke)能會導(dao)致連接(jie)器過熱甚至損壞。接(jie)觸電(dian)(dian)阻(zu)則影(ying)響信號傳(chuan)輸的穩定(ding)性(xing)，低接(jie)觸電(dian)(dian)阻(zu)可(ke)以(yi)減(jian)少信號衰減(jian)和能量損耗。

 其(qi)次是(shi)機械(xie)(xie)性(xing)(xing)(xing)(xing)能(neng)(neng)，如插(cha)拔(ba)(ba)力、機械(xie)(xie)壽命(ming)和抗振(zhen)(zhen)(zhen)(zhen)性(xing)(xing)(xing)(xing)等(deng)。合(he)適(shi)的(de)(de)插(cha)拔(ba)(ba)力可以保證連(lian)接(jie)的(de)(de)便(bian)利性(xing)(xing)(xing)(xing)和可靠性(xing)(xing)(xing)(xing)，機械(xie)(xie)壽命(ming)長意味著(zhu)連(lian)接(jie)器(qi)(qi)能(neng)(neng)夠經(jing)受多次插(cha)拔(ba)(ba)而(er)不(bu)損壞。抗振(zhen)(zhen)(zhen)(zhen)性(xing)(xing)(xing)(xing)對于在(zai)振(zhen)(zhen)(zhen)(zhen)動環(huan)境(jing)中使(shi)用的(de)(de)連(lian)接(jie)器(qi)(qi)尤為重要，它能(neng)(neng)確保在(zai)振(zhen)(zhen)(zhen)(zhen)動情況(kuang)下連(lian)接(jie)依然穩定。此外，環(huan)境(jing)適(shi)應性(xing)(xing)(xing)(xing)也是(shi)不(bu)可忽視的(de)(de)因素，如溫度范圍、濕度、鹽霧等(deng)。不(bu)同(tong)(tong)的(de)(de)工作環(huan)境(jing)對連(lian)接(jie)器(qi)(qi)的(de)(de)性(xing)(xing)(xing)(xing)能(neng)(neng)有(you)不(bu)同(tong)(tong)的(de)(de)要求，須根(gen)據實(shi)際情況(kuang)選擇(ze)合(he)適(shi)的(de)(de)連(lian)接(jie)器(qi)(qi)。
