Chiyambi cha Ntchito ya Zophimba Zachitsulo pa Ma Terminal Blocks

Ntchito za zokutira zitha kugawidwa m'magulu atatu: ntchito zoteteza, ntchito zamagetsi, ndi ntchito zamakina/njira.
1. Ntchito yoteteza (kukana dzimbiri ndi kulimba)
Iyi ndiye ntchito yofunika kwambiri komanso yofunika kwambiri ya chophimba.
- Kuletsa kukhuthala kwa substrate ndi dzimbiri: Copper imatha kupanga copper oxide kapena copper sulfide ikakumana ndi mpweya wonyowa kapena malo okhala ndi sulfure. Mankhwalawa ali ndi mphamvu yotsika kwambiri yoyendetsera mpweya ndipo amatha kupanga chotetezera kutentha, zomwe zimapangitsa kuti pakhale kukana kwadzidzidzi kwa kukhudzana, zomwe zingayambitse kulephera kwa kutentha kapena ngakhale kulephera kwa dera. Chophimbacho chimagwira ntchito ngati "chotchinga" cholimba, chomwe chimalekanitsa substrate ndi malo akunja.
- Kupititsa patsogolo kusinthasintha kwa chilengedwe: Pa malo osiyanasiyana ogwiritsira ntchito (monga kutentha kwambiri ndi chinyezi, kupopera mchere, ndi mpweya wa mankhwala m'mafakitale), kusankha chophimba choyenera kungathandize kwambiri kukana dzimbiri kwa malo osungiramo zinthu. Mwachitsanzo, nickel kapena chromium plating imagwira ntchito bwino kwambiri m'malo ovuta a mafakitale.

2. Ntchito yamagetsi (kutsimikizira magwiridwe antchito a conductive)
- Kukhazikitsa ndi kuchepetsa kukana kukhudzana: Kupereka malo oletsa kukhudzana: zokutira monga tin ndi siliva zimakhala ndi mphamvu yabwino yoyendetsera magetsi ndipo sizimawotchedwa, zomwe zimapangitsa kuti magetsi aziyenda bwino komanso azikana kukhudzana ndi magetsi.
- Kuswa mafilimu oteteza okosijeni: Zophimba zambiri (makamaka zitsulo za tin ndi tin) zimakhala zofewa. Pamene zophimbazo zapindika kapena zomangira zalimbikitsidwa, zophimbazo zimatha kusintha pang'ono ndikuyenda, kuboola waya kapena filimu ya okosijeni pamwamba pa zolumikizira, zomwe zimathandiza kuti kukhudzana mwachindunji pakati pa chitsulo ndi chitsulo (monga "kukhudzana kwachitsulo"), zomwe zimachepetsa kwambiri kukana kukhudzana.
- Kusunga kukhazikika kwa magetsi kwa nthawi yayitali: Zophimba zapamwamba zimatha kusunga mawonekedwe awo pamwamba pakapita nthawi, kupewa kukana kwa dzimbiri komanso kuonetsetsa kuti magetsi akugwirizana bwino nthawi yonse ya moyo wa chinthucho.

Ntchito za Makina ndi Kukonza
Konzani Kugwirizana kwa Kugwirizana: Pa ma terminal omwe amafunikira kuwotcherera (monga ma terminal a PCB), kuwotcherera ndikofunikira kwambiri. Kuwotcherera kwa tin ndi tin-lead alloy kumakhala ndi kuthekera kogwirizana bwino kwambiri, kuonetsetsa kuti zolumikizira zolumikizana zimakhala zachangu, zolimba, komanso zodalirika. Kugwirizana kwa mkuwa woyera kumachepa kwambiri pambuyo pa kusungunuka kwa pamwamba, ndipo kuwotcherera kumapereka malo ogwirizana ogwirizana kwa nthawi yayitali.
Kuonjezera Kukana Kuvala: Ma terminal nthawi zambiri amachitidwa ntchito monga kulumikiza ndi kuchotsa ma plug kapena kulimbitsa ma screws akagwiritsidwa ntchito. Zophimba zolimba monga nickel kapena chrome plating zimatha kuwonjezera kuuma kwa pamwamba, kuchepetsa kuwonongeka chifukwa choziyika mobwerezabwereza, ndikuwonjezera nthawi ya ntchito. Zimathandizanso kupewa kuwonekera kwa zinthu zowononga zomwe zili pansi chifukwa cha kuwonongeka.
Chepetsani Kukangana kwa Malo Okhudzana ndi Kukhudza: Ma plating ena (monga tin) ali ndi mphamvu zodzipaka okha, zomwe zimapangitsa kuti zomangira za screw zikhale zosalala, mphamvu yolimba, komanso kuchepetsa kusokonekera kwa zitsulo.
