網(wǎng)絡(luò)優(yōu)化資料:


連接器工作時,電流在接觸點產(chǎn)生熱量,導(dǎo)致溫升,所以一般認(rèn)為工作溫度應(yīng)該等于環(huán)境溫度和接觸點溫升之和。在一些規(guī)范中,明確規(guī)定了額定工作電流下連接器的允許溫升。

②防潮性的侵入會影響連接H和生銹金屬部件的絕緣性能。恒定濕熱試驗條件為相對濕度90%~95%,溫度+40±20℃,試驗時間按產(chǎn)品規(guī)定至少96小時。濕熱交替試驗更厲害。

③耐鹽霧連接器在含有濕氣和鹽的環(huán)境中工作時,金屬結(jié)構(gòu)件和接觸件的表面處理層可能發(fā)生電化學(xué)腐蝕,pin針標(biāo)準(zhǔn)可能影響連接器的物理和電氣性能。為了評估電連接器承受這種環(huán)境的能力,規(guī)定了鹽霧試驗。連接器懸掛在溫控試驗箱中,形成鹽霧環(huán)境,pin針其暴露時間至少為產(chǎn)品規(guī)范規(guī)定的48小時。

(4)振動和沖擊抗振動和沖擊是電連接器的重要性能,是檢驗電連接器機械結(jié)構(gòu)牢固性和電接觸可靠性的重要指標(biāo)。相關(guān)測試方法有明確規(guī)定。沖擊試驗中應(yīng)規(guī)定峰值加速度和電氣連續(xù)性的中斷時間。

⑤其他環(huán)境性能根據(jù)使用要求,電連接器的其他環(huán)境性能包括密封性能和低氣壓。
