Terminals galibi suna da kaddarorin asali guda 3: kayan aikin injiniya, kayan lantarki da kaddarorin muhalli.

　　1. Aikin lantarki

　　Lokacin da ake amfani da tashar a matsayin hanyar haɗi, da farko, aikin dole ne ya zama aikin lantarki.

　　Yawanci sun haɗa da: juriya na lamba, juriya na insulation da ƙarfin dielectric. Lambobin sadarwa da tsakanin lambobin sadarwa da harsashi.

　　3. Ƙarfin dielectric shine tsayayyar ƙarfin lantarki da ƙarfin lantarki mai jurewa. mai haɗawa. Ƙarfin shigarwa da cirewa da rayuwar injiniya na tashar tashar suna da alaƙa da tsarin lamba (matsi mai kyau), ingancin suturar sashin lamba (madaidaicin juzu'i mai zamewa) da daidaiton girman (daidaitawa) na tsarin lamba.

3. Ayyukan muhalli

　　Kayan abubuwan muhalli na yau da kullun sun haɗa da: juriya na zafin jiki, juriya na zafi, juriya na feshin gishiri, rawar jiki da juriya, da sauransu.

　　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.
