Awọn ebute ni akọkọ ni awọn ohun-ini ipilẹ mẹta: awọn ohun-ini ẹrọ, awọn ohun-ini itanna ati awọn ohun-ini ayika.

　　1. Iṣẹ itanna

　　Nigbati a ba lo ebute naa bi okun waya asopọ, ni akọkọ, iṣẹ naa gbọdọ jẹ iṣẹ itanna.

　　Ni akọkọ pẹlu: resistance resistance, idabobo idabobo ati agbara dielectric. awọn olubasọrọ ati laarin awọn olubasọrọ ati awọn ikarahun.

　　3. Agbara dielectric jẹ foliteji resistance ati dielectric withstand foliteji. asopo. Fi sii ati agbara isediwon ati igbesi aye ẹrọ ti ebute naa ni ibatan si ọna olubasọrọ (titẹ to dara), didara ibora ti apakan olubasọrọ (alafisọfitiwia sisun sisun) ati deede iwọn (titete) ti iṣeto olubasọrọ.

3. Iṣẹ ayika

　　Awọn ohun-ini ayika ti o wọpọ pẹlu: resistance otutu, resistance ọriniinitutu, resistance sokiri iyọ, gbigbọn ati idena mọnamọna, ati bẹbẹ lọ.

　　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.
