Terminals tumadi nwere 3 isi Njirimara: n'ibu Njirimara, eletriki Njirimara na gburugburu ebe obibi Njirimara.

　　1. Eletriki arụmọrụ

　　Mgbe a na-eji ọnụ ọnụ dị ka eriri njikọ, nke mbụ, arụmọrụ ga-abụrịrị arụmọrụ eletrik. @　　Tuchaa gụnyere: nguzogide kọntaktị, nguzogide mkpuchi na ike dielectric. kọntaktị na n'etiti kọntaktị na shei.

　　3. The dielectric ike bụ iguzogide voltaji na dielectric na-eguzogide voltaji. njikọ. Ntinye na mmịpụta ike na ndụ igwe nke ọdụ ụgbọ ala jikọtara ya na nhazi kọntaktị (nrụgide dị mma), mma mkpuchi nke akụkụ kọntaktị (ntụgharị esemokwu sliding) na nha nha (nhazi) nke nhazi kọntaktị.

3. Environmental performance

　　Akụkọ gburugburu ebe obibi na-agụnye: okpomọkụ na-eguzogide, iru mmiri na-eguzogide, nnu ịgba mmiri, vibration na ujo iguzogide, wdg.

　　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.
