Zomwe zimayambitsa kuwonongeka kwa terminal ndi njira zodzitetezera

Chifukwa chiyani ma oxidation ndikuda kwa ma terminals?

Njira yogwiritsira ntchito makampani otsiriza nthawi zambiri imabweretsa chitukuko cha mavuto osiyanasiyana, monga kwa ife akhoza kukhala oxidation wakuda wakuda, ngati oxidation yakuda yakuda kunja padzakhala wosanjikiza wa zinthu monga mwaye, womwe umapangidwa ndi okosijeni, ndi kupanga zinthu zakuda, kugwiritsa ntchito sandpaper kapena fayilo pogaya.

Monga tonse tikudziwira, ma terminals omwe ali ndi kuchuluka kwa makina opangira mafakitale komanso zofunikira zowongolera mafakitale zimakhala zolimba kwambiri, ndipo kuchuluka kwa ma terminal kumakwera pang'onopang'ono. Ndi chitukuko cha mafakitale a zamagetsi, kugwiritsa ntchito ma terminals mochulukirapo, ndi mitundu yambiri. Terminals kuti atsogolere kugwirizana kwa mawaya ndi ntchito, ndi gawo la chisindikizo mu insulating pulasitiki pamwamba golide, malekezero onse ali ndi mabowo kuti akhoza anaikapo mu waya, ndipo pali zomangira yomanga kapena kumasula, monga awiri. mawaya, nthawi zina amafunika kulumikizidwa, nthawi zina amafunika kulumikizidwa, nthawi ino mutha kugwiritsa ntchito ma terminals kuti muwalumikize ndipo amatha kulumikizidwa nthawi iliyonse, osawawotcherera kapena zopindika pamodzi, ndizosavuta komanso zachangu.

Komabe, nthawi zina pakhoza kukhala mtundu woterewu wa kumasulidwa kwamtunduwu chifukwa cha kukana kukhudzana ndi anthu kukhala kwakukulu, motero kumatulutsa kutentha; ma terminals sakhala otayirira, koma chifukwa cha dera chifukwa chazifukwa zina zosadziwika zachilengedwe komanso kutentha kwapang'onopang'ono, monga makonzedwe amagetsi amagetsi ndi okwera kwambiri, kapena kutsika kwafupipafupi, komwe kungayambitsenso makutidwe ndi okosijeni omaliza ndikuda. Choncho, zomwe zimayambitsa makutidwe ndi okosijeni ndi mavuto akuda a ma terminals akuphatikizapo mfundo ziwiri zotsatirazi.

1.magetsi ndi okwera kwambiri. Itha kufufuzidwa kuchokera ku gwero, thiransifoma yachiwiri voteji voteji mu bokosi yogawa - voteji wa aliyense zida mphamvu. Ma sockets amathanso kukhala ndi zomangira zomangirira komanso zotsekera. Kumangirira msonkhano kumatha kusewera molimba kwambiri pa bolodi la PCB, kutseka kotseka kumatha kukhazikitsidwa mukamaliza kutseka mayi ndi socket.

Mapangidwe osiyanasiyana a socket alipo kuti agwirizane ndi njira zosiyanasiyana zoyikamo akazi, monga zopingasa, zoyima, kapena zopindika ku PCB. Ma metric ndi ma standard wire geji onse alipo.

2. cholakwika chapansi. Mukhozanso kuyang'ana kuchokera ku thiransifoma kumeneko, ndiyeno ku gawo logawa bokosi. Kuyika pansi kuyenera kukhala kokhazikika, pomwe mawaya anthawi zonse ayenera kuchotsedwa ku zolakwika zapansi. Itha kuzimitsidwa ndi mita ya insulated kapena kugwedeza tebulo kuti muyeze, ndi miyeso ya gawo, kuyesa magawo a zingwe, mawaya, zowononga dera, masiwichi, ndi mizere ina yamagetsi ndi kugawa, ndikovuta kugawa mlanduwo, ikutulutsa zida zofooka, zida zomverera, ma fuse.

Chinsinsi cha kuyika pansi ndi kukana kwapansi kuyenera kukhala kotsika, pomwe malo olumikizirana ayenera kukhala akulu. Yoyambayo imatha kuonetsetsa kuti malo oyambira ali ndi kuthekera pafupi ndi kuthekera kwa dziko lapansi motsika momwe angathere ziro, zomwe zingakulepheretseni kuganiza za bingu, kapena mphezi kuchokera pamzere woyambira kumbuyo kupita, kuthamangira kutheka kwa magetsi. dera.

Omalizawa amatha kuonetsetsa kuti pali mphamvu zokwanira zoperekera njira yolakwika, kuphatikizapo mphezi kapena zolakwika zafupipafupi ndi zina zotero. Chifukwa ndondomeko yeniyeni yomangayi yakhazikitsidwa pa chiphunzitso cha zamakono zamakono ndi kusintha kwaumisiri ndi kusintha, njira yokhazikitsirayi ndi yotheka, yabwino kapena yoipa, komanso kuona momwe ndondomeko yatsopanoyi ikugwiritsidwira ntchito.

Kulumikizana komaliza ndi vuto loyipa

Ma Terminals mu unsembe ndondomeko, ngati pali kugwirizana zoipa, zidzakhudza ntchito yachibadwa anthu, ndipo n'zosavuta oxidize wakuda.

Kuyika kolondola ndi kugwiritsa ntchito ma terminals kumatha kuwonetsetsa kuti makina opanga magetsi kuti apewe kuchitika kwa zolakwika za waya, chifukwa chake, kukhazikitsa ma terminal ndikofunikira kwambiri. Ngati pali kusowa kwa njira zamakono zogwirira ntchito pomanga, ntchito yoyenera ya ma terminals sangathe kusewera kwathunthu. Choncho, tcheru chiyenera kuperekedwa ku gulu lapadera la ma terminals, chifukwa mitundu yosiyanasiyana ya njira zoyikira zofanana ndizosiyana kwambiri. Mwachitsanzo, mtundu wa plug-in uyenera kulowetsedwa bwino kuti upereke kusewera koyenera. Mtundu wa block block ndi mtundu wa zochulukirapo, unsembe uyenera kutengera momwe zinthu zilili posankha njira yoyenera.

Mukayika, muyenera kusankha ma terminal omwe ali ndi luso loyenera kupewa zovuta zachitetezo zomwe zimayambitsidwa ndi zinthu zosayenerera. Mukayika ma terminals, muyenera kusankha zinthu zoyenera kukula molingana ndi momwe zilili, ndikugawa moyenerera katundu wa magawo atatu, osati kungoganizira za chuma chamagetsi, komanso kuzindikira chitetezo chamagetsi. Mukayika chipika cholumikizira, malo olumikiziranawo ayenera kupukutidwa bwino ndikukutidwa ndi phala la conductive, kuti chotchinga cha terminal ndi cholumikizira cholumikizira chikhale chabwino kuti chikwaniritse zofunikira za mphamvu ziwiri zolumikizirana ndi magwiridwe antchito amagetsi kuti muchepetse mwayi wotulutsa kutentha. . Momwe zingakhudzire chitetezo cha mizere yokhudzana ndi ma terminal, ziyenera kukonzedwa mwachangu. Iyenera kuyang'aniridwa nthawi zonse ndi chingwe chotsogolera ku mzere wogawa, kuchepetsa zotumphukira zolakwika ndi mizere yogawa zoopsa zachilengedwe.

Ngati chipikacho chiwonongeka chikugwiritsidwa ntchito, sichingagwiritsidwe ntchito popanga kwenikweni. Zomwe zimayambitsa kuwonongeka ndi chiyani? Ngati mawaya odulidwa a block block ndiafupi kwambiri, malo omangira masika amakhala ochepa, zomwe zingayambitse kuthamangitsidwa. Kwa kuvula, osati kukhala ndi chidziwitso chochuluka chogwiritsira ntchito, komanso kukhala ndi chida chapadera chochotsera kuti chikonze kutalika kwa kuvula. Ma Terminals ali ndi zofunikira zosiyanasiyana pagawo la waya. Ngati sichikukwaniritsa zofunikira, ma waya amatha kulowetsedwa mokwanira m'mabowo a ma terminals, zomwe zimapangitsa kuchepa kwa conductivity ndi mavuto obisika.

Kutalika kwa crimp ndi makulidwe a block block ayenera kukwaniritsa zofunikira. Pamene wayayo ndi woonda kwambiri, chifukwa cha kusungunula pakati pa waya ndi malo okhudzana nawo komanso kuponderezedwa kwa nthawi yaitali kwa waya, ma conductivity a waya amawonongeka, motero amawotcha ma terminals.
