Zolumikizira zolumikizira magalimotom'munda wa zomangira mawaya magalimoto ndi mbali yofunika ya munda, komanso mwachindunji kudziwa cholumikizira chizindikiro ndi mphamvu kufala mfundo zofunika. Ndi chitukuko chofulumira chamakampani opanga magalimoto ku China, kupititsa patsogolo kopitilira muyeso kwa gawo lamagalimoto kumalimbikitsanso cholumikizira chagalimoto kuti chitukuke komanso chodalirika.
Powunikiranso zovuta zam'mbuyomu pakugwiritsa ntchito zolumikizira zolumikizira, tapeza kuti zotsatirazi zikhudza kuthekera kotumizira ma terminals: zida, kapangidwe kake, mawonekedwe apamwamba, komanso kupindika.
Zinthu za terminal
Poganizira magwiridwe antchito ndi chuma, makampani olumikizira m'nyumba nthawi zambiri amagwiritsa ntchito zida ziwiri: mkuwa ndi mkuwa. Mkuwa nthawi zambiri umakhala wabwino, koma mkuwa wosinthika kwambiri. Popeza mapulagi ndi ma socket terminals momwe amasiyana, nthawi zambiri amaika patsogolo kugwiritsa ntchito mapulagi m'malo mwa mkuwa wowongolera. Ma socket terminals nawonso amakhala ndi mawonekedwe osinthika, poganizira zofunikira za conductivity, ndipo nthawi zambiri amasankha zida zamkuwa kuti zitsimikizire kudalirika kwa ma terminal shrapnel.
Pazofunikira zokhazikika zazitsulo zazitsulo, chifukwa cha kusinthika kwa zinthu zamkuwa zomwe sizikutha kukwaniritsa zofunikira, chizoloŵezi chachikulu ndicho kusankha zipangizo zamkuwa zamkuwa, poganizira zolakwika za zinthu zamkuwa zomwe zimakhala zosasinthika, elasticity idzachepa. Pamapangidwewo onjezerani chokhazikika chothandizira kuti muwonjezere kusungunuka kwa ma terminals. Monga momwe chithunzi (1).
Chithunzi 1 Chithunzi chojambula cha socket terminal yokhala ndi chithandizo cholimba
M'mafotokozedwe omwe ali pamwambawa a mawonekedwe otsiriza omwe ali ndi chithandizo chokhwima mu Chithunzi (2), mawonekedwe okhwima othandizira amawongolera kupanikizika kwabwino kwa conductive laminating pamwamba, motero kumapangitsa kudalirika kwa mankhwala.
Chithunzi 2 Chithunzi cha socket terminal yokhala ndi chithandizo cholimba
Mapangidwe a mapangidwe
M'malo mwake, kapangidwe kake kamangidwe kameneka kamakhala kotseguka kuti achepetse mtengo wazinthu zopangira, ndikusunga mphamvu zotumizira ma terminals. Chifukwa chake, ma terminals olumikizira amakhala pachiwopsezo chachikulu cha kufalikira kwa mphamvu monga gawo la "bottleneck" yawo, yomwe imatanthawuza ma terminals omwe ali pamtunda wowongolera wagawo laling'ono kwambiri la kapangidwe kake. Monga momwe tawonetsera mu Chithunzi (3), kapangidwe kameneka kakukhudza mwachindunji mphamvu yonyamulira ya terminal.
Chithunzi 3 Chithunzi chojambula cha kukula kwa ma terminal
Chithunzi 3b chikuwonetsa kuti gawo la S1 ndilokulirapo kuposa S2, kotero gawo la BB lili m'botolo. Izi zikuwonetsa kuti, popanga mapangidwe, gawo lodutsa liyenera kukwaniritsa zofunikira za terminal.
Kuyika pamwamba
Pazolumikizira zambiri, plating ndi njira yodziwika bwino yopumira. Kuipa kwa plating plating kumaphatikizapo izi ziwiri: choyamba, plating plating idzachepetsa kusungunuka komanso kuwonjezereka kwa kukhudzana, zomwe makamaka zimachokera ku plating ndi zitsulo intermetallic chitetezo pakati pa zitsulo. Kachiwiri, zinthu zolumikizana nazo zimakhala ndi mikangano yapamwamba kwambiri poyerekeza ndi zitsulo zopangidwa ndi zitsulo, zomwe zimapangitsa kuti pakhale mphamvu yowonjezera yolumikizira, makamaka pazitsulo zamawaya ambiri.
Chifukwa chake, pakuyika zolumikizira za ma multiwire, njira zatsopano zomangira zimagwiritsidwa ntchito ngati kuli kotheka kuwonetsetsa kusuntha kwa kulumikizana ndikuchepetsa kuyika kwapano. Mwachitsanzo, plating golide ndi njira yabwino plating.
Kuchokera pamawonedwe ang'onoang'ono, malo aliwonse osalala amakhala ndi malo ovuta komanso osagwirizana, kotero kukhudzana kwa ma terminals ndiko kukhudzana ndi mfundo osati kukhudzana ndi pamwamba. Kuonjezera apo, malo ambiri azitsulo amaphimbidwa ndi osayidi osayendetsa-conductive ndi mitundu ina ya zigawo za filimu, kotero kokha m'lingaliro lenileni la malo okhudzana ndi magetsi - otchedwa "conductive spots - ndizotheka kukhala ndi magetsi.
Monga ambiri a kukhudzana ndi kudzera filimu kukhudzana, pamene panopa ndi kudzera mbali ziwiri kukhudzana kwa mawonekedwe, izo kuganizira anthu ang'onoang'ono conductive mawanga.
Choncho, pafupi ndi madontho a conductive a mzere wamakono adzakhala mgwirizano, zomwe zimabweretsa kuwonjezeka kwa kutalika kwa njira yomwe ikuyenda panopa, ndipo malo oyendetsa bwino amachepetsedwa. Kukaniza kumeneku kumatchedwa "shrinkage resistance" ndipo kumapangitsa kuti ma terminals azitha komanso kufalikira kwa ma terminals.
Pakalipano, pali njira ziwiri zowunika momwe plating ikuyendera: choyamba, kuwunika makulidwe a plating. Njira imeneyi imawunika ubwino wa zokutira poyesa makulidwe a zokutira. Chachiwiri, mtundu wa plating umawunikidwa pogwiritsa ntchito mayeso oyenera opopera mchere.
Kuthamanga kwabwino kwa ma terminal shrapnel
Connector terminal positive pressure ndi chizindikiro chofunikira cha magwiridwe antchito a cholumikizira, chomwe chimakhudza mwachindunji mphamvu yoyika ma terminal ndi mphamvu zamagetsi. Zimatanthawuza cholumikizira pulagi terminal ndi socket terminal contact surface perpendicular to contact surface force.
Pogwiritsa ntchito ma terminals, vuto lomwe limafala kwambiri ndi mphamvu yoyika pakati pa terminal ndi terminal control siyikhazikika. Izi zimachitika chifukwa cha kupanikizika kosakhazikika kwa shrapnel, komwe kumayambitsa kukana kwa malo olumikizana ndi terminal. Izi zimabweretsa kuwonjezeka kwa kutentha kwa ma terminals, zomwe zimapangitsa kuti cholumikizira chiwotchedwe komanso kutayika kwa conductivity, kapena ngakhale zitavuta kwambiri, kutopa.
Malinga ndi QC/T417 [1], kukana kukhudzana ndi kukana pakati pa malo olumikizirana ndi cholumikizira ndipo kumaphatikizapo zinthu izi: kukana kwapakatikati kwa ma terminals, kukana komwe kumabwera chifukwa cha crimping ya ma conductor, kukana kwa waya. pa mfundo, ndi kukana kwa shrapnel wa pulagi ndi zitsulo materminal kukhudzana (mkuyu. 4).
Zinthu za terminal zimakhudza kwambiri kukana kwamkati, mtundu wa crimping wa chinthucho umakhudza kukana komwe kumapangidwa ndi conductor crimp, plug terminal ndi socket terminal shrapnel pokhudzana ndi kukana kopangidwa ndi mawonekedwe a terminal, komanso kukwera kwa kutentha kwa kufunika kwachikoka chachikulu. Choncho, pakupanga mfundo zazikuluzikulu.
Chithunzi4 Chithunzi chojambula cha kukana kukhudzana
Kuthamanga kwabwino pa terminal kumadalira kutha kwa kumapeto kwa lilime lachipolopolo. Radiyo yopindika R ndi kutalika kwa cantilever L ya lilime imakhala ndi chikoka chachindunji pamtengowu ndipo iyenera kuganiziridwa panthawi yopanga. Mapangidwe a ma terminal shrapnel akuwonetsedwa Chithunzi 5.

Kuphwanya mchira
Ubwino wotumizira wa terminal umakhudzidwa mwachindunji ndi mtundu wa crimping wa terminal. Kutalika ndi kutalika kwa crimp kumakhudza kwambiri khalidwe la crimp. Crimp yolimba imakhala ndi mphamvu zamakina komanso mphamvu zamagetsi, kotero miyeso ya gawo la crimp iyenera kuyendetsedwa mosamalitsa. Kuchuluka kwa waya ndi chinthu chofunikira chomwe chimapangitsa kuti crimping ichitike pakati pa terminal ndi waya.
Kuphatikiza apo, waya wokha ndiwofunikanso kuphunzira, chifukwa zinthu zapakhomo ndi zakunja zili ndi mawonekedwe awoawo. Pakupanga kwenikweni, mfundo zotsatirazi ziyenera kuwonedwa: chingwe cha waya chiyenera kufanana ndi mapeto a terminal, kutalika kwa mutu wa mutu uyenera kukhala wochepa, ndi nkhungu yoyenera ya crimping, crimping pambuyo pa mayeso a Rattori.
Yang'anani njira zowonongera ma terminal kuphatikiza kuyang'ana mbiri ya terminal crimping ndi mphamvu yokoka. Poyang'ana mbiriyo, mutha kuyang'ana zotsatira za crimping kuti muwonetsetse kuti palibe zolakwika monga kusowa kwa mawaya amkuwa kapena kutsika. Kuonjezera apo, mphamvu yokoka imayesa kudalirika kwa crimp.
