另一個(gè)重要的機(jī)械性能是連接器的機(jī)械壽命。機(jī)械壽命實(shí)際上是一種耐久性(durability)指標(biāo),在國(guó)標(biāo)GB5095中把它叫作機(jī)械操作。它是以一次插入和一次拔出為一個(gè)循環(huán),以在規(guī)定的插拔循環(huán)后連接器能否正常完成其連接功能(如接觸電阻值)作為評(píng)判依據(jù)。連接器的插拔力和機(jī)械壽命與接觸件結(jié)構(gòu)(正壓力大小)接觸部位鍍層質(zhì)量(滑動(dòng)摩擦系數(shù))以及接觸件排列尺寸精度(對(duì)準(zhǔn)度)有關(guān)。
電氣性能
電氣性能連接器的主要電氣性能包括接觸電阻、絕緣電阻和抗電強(qiáng)度。
①接觸電阻高質(zhì)量的電連接器應(yīng)當(dāng)具有低而穩(wěn)定的接觸電阻。連接器的接觸電阻從幾毫歐到數(shù)十毫歐不等。
②絕緣電阻衡量電連接器接觸件之間和接觸件與外殼之間絕緣性能的指標(biāo),其數(shù)量級(jí)為數(shù)百兆歐至數(shù)千兆歐不等。
③抗電強(qiáng)度或稱耐電壓、介質(zhì)耐壓,是表征連接器接觸件之間或接觸件與外殼之間耐受額定試驗(yàn)電壓的能力。
環(huán)境性能
環(huán)境性能常見的環(huán)境性能包括耐溫、耐濕、耐鹽霧、振動(dòng)和沖擊等。
