接線板接頭的基本性能。

對接線板連接件的基本性能可以分為三類:機械性能、電氣性能和環(huán)境性能。

聯(lián)接功能而言,拉力對地面的機械性簡易牛角能至關(guān)重要。拉拔力分為拉拔力和拉拔力(又稱分離力),二者對拉拔力的要求有所不同。相關(guān)標(biāo)準(zhǔn)中規(guī)定了大插接力和最小分離力,這表明從使用角度看,插接力較小(因此LIF的插接力較低,ZIF的結(jié)構(gòu)的插接力較低),分接力排針單排如果過小,將影響觸點的可靠性。

另外重要的機械性能是板對接頭的機械壽命。機器壽命實際上是一種耐久性指標(biāo),國標(biāo)GB5095將其稱為機械操作壽命。以插入式和拔出式為一個循環(huán),以連接器在規(guī)定的插拔式循環(huán)之后是否能正常完成其連接功能(如接觸電阻值)為判斷標(biāo)準(zhǔn)。

對中接頭的拉力和機械壽命與觸點結(jié)構(gòu)(正壓面)接觸部位的鍍層質(zhì)量(滑動摩擦系數(shù))和觸點排列尺寸精度(對中)有關(guān)。
