Terminalku waxay inta badan leeyihiin 3 siyaalood oo aasaasi ah: Qalabka farsamada, guryaha korantada iyo guryaha deegaanka.

　　1. Waxqabadka korontada @　　Inta badan waxaa ka mid ah: caabbinta xiriirka, caabbinta dahaarka iyo xoogga dielectric. Xidhiidhada iyo inta u dhaxaysa xidhiidhada iyo qolofka. xiriiriyaha. Gelitaanka iyo soo saarista xoogga iyo nolosha farsamada ee terminalku waxay la xiriiraan qaab dhismeedka xiriirka (cadaadiska togan), tayada daahan ee qaybta xiriirka (isku-dhafka qulqulaya qulqulaya) iyo saxnaanta cabbirka (isugeynta) habka xiriirka.

3. Waxqabadka deegaanka

　　Alaabooyinka deegaanka ee caadiga ah waxaa ka mid ah: caabbinta heerkulka, caabbinta huurka, iska caabinta milixda, gariir iyo caabbinta shoogga, iwm.

　　1. Contact resistance, high-quality electrical connectors should have low and stable contact resistance.

　　2. Insulation resistance, a measure of the insulation performance between terminal contacts and between the contacts and the shell.

　　3. The dielectric strength is the withstand voltage and the dielectric withstand voltage.

　　2. Mechanical properties

　　The mechanical performance mainly includes the insertion force and the mechanical life of the connector. The insertion and extraction force and mechanical life of the terminal are related to the contact structure (positive pressure), the coating quality of the contact part (the sliding friction coefficient ) and the dimensional accuracy (alignment) of the contact arrangement.

　　3. Environmental performance

　　Common environmental properties include: temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance, etc.
