Monga cholumikizira wamba kwa mainjiniya onse, midadada yotsekera yakhala ikugwiritsidwa ntchito kwa zaka zambiri kuti ipereke mawaya otetezeka osakhazikika pazogwiritsa ntchito zosiyanasiyana.Chotsekera, chomwe chimatchedwanso terminal block, terminal cholumikizira, kapena cholumikizira cha ulusi, chimakhala ndi modular nyumba ndi insulator yomwe imalumikiza mawaya awiri kapena kuposerapo palimodzi.Chifukwa cholumikizira ndi chokhazikika, chotchinga cha terminal chimathandizira kuyang'anira ndikukonza njira.Ngakhale ndi gawo losavuta, koma musanasankhidwe kwa block terminal ndi mafotokozedwe ake ali ndi chidziwitso choyambirira kapena chabwino.

Kukambitsiranaku kudzakhudza mitundu yofananira ya block block, zofunikira zamagetsi ndi zamakina, ndikupereka zina zambiri zothandizira mainjiniya pakusankha.

Kukonzekera wamba

Mtundu wokwera wa PCB, mtundu wa mpanda ndi mtundu wowongoka ndi mitundu itatu yodziwika bwino ya block block pamapangidwe.Gome lotsatirali likutchula mitundu itatu yosiyanasiyana ndi zomveka, kukhazikitsa, ndi kasinthidwe.

Zofunika Zamagetsi

Pali zofunikira zingapo zamagetsi zomwe ziyenera kuganiziridwa panthawi yopangira, zomwe zimakhudza mitundu ya block terminal.Muphatikizepo:

Zovoteledwa panopa.Nthawi zambiri, zomwe zimafunikira chidwi kwambiri pakupanga bokosi lolumikizana ndizomwe zidavotera.Izi zimachokera pazigawo zitatu: madulidwe amagetsi a ma terminals, malo odutsa ndi kutentha kofananako.Posankha midadada yama terminal, tikulimbikitsidwa kuti zomwe zidavotera zizikhala zosachepera 150% yazomwe zikuyembekezeka pakali pano.Ngati mphamvu yovotera ya terminal block ndi yolakwika ndipo ntchitoyo ili yokwera kwambiri, chotchinga cha terminal chikhoza kutenthedwa ndikuwonongeka, zomwe zimabweretsa zovuta zachitetezo.
Ma voliyumu ovoteledwa: Gawo la voliyumu lovotera la terminal block limakhudzidwa ndi malo komanso mphamvu ya dielectric ya nyumba yake.Momwemonso momwe ma voliyumu amasankhidwa, ma voliyumu ovotera a terminal block ayenera kukhala akulu kuposa ma voliyumu apamwamba a dongosololi, poganizira kuchuluka kwamagetsi komwe kungawononge kulumikizana.
Chiwerengero cha mitengo: Chiwerengero cha mitengo ndi njira yodziwika bwino yofotokozera kuchuluka kwa mabwalo odziyimira pawokha omwe ali mu block block.Izi nthawi zambiri zimasiyanasiyana kuchokera ku unipolar mpaka 24.
Kutalikirana: Kutalikirana kumatanthauzidwa ngati mtunda wapakati pakati pa mizati yoyandikana, yomwe imatsimikiziridwa ndi mlingo wonse wa chipika cha terminal ndipo imaphatikizapo zinthu monga creepage mtunda, magetsi / panopa, ndi chilolezo.Zitsanzo zina zodziwika bwino zamatalikirana ndi 2.54mm, 3.81mm, 5.0mm, ndi zina.
Kukula kwa waya/Mtundu: Ku North America, mawaya ovomerezeka ku midadada ya terminal ali mu American Wire gauge (AWG), yomwe imatchula kukula kwa waya kapena geji yovomerezeka ya module kuti zitsimikizire kuti wayayo ikulowa mnyumbamo.Mwamwayi, mipiringidzo yambiri imakhala ndi zololera zomwe zimatha kutengera kukula kwa waya monga 18 mpaka 4 kapena 24 mpaka 12AWG.Kuphatikiza pa kuwunika kwa waya, ganizirani mtundu wa waya kutengera mtundu wa module yosankhidwa.Mawaya opindika kapena amitundu yambiri ndi abwino kwa ma terminals okhala ndi ulusi, pomwe mawaya amtundu umodzi nthawi zambiri amalumikizidwa ndi midadada yolowera mkati.
Zofunikira zamakina

Kenako pamabwera mawonekedwe amakina, omwe amakhudzana ndi kukula kwa chotchinga chotchinga, komwe kumayendera, komanso kusavuta kugwiritsa ntchito kulumikizana pamapangidwewo.Zofunikira zamakina ndi izi:

Mayendedwe a mawaya: Chopingasa (90°), ofukula (180°) ndi 45° ndi njira zitatu zodziwika bwino za midadada.Kusankha kumeneku kumadalira kamangidwe kameneka ndi komwe kuli koyenera komanso kosavuta kwa mawaya.
Chithunzi 1: Njira yokhazikika yotsekera (chithunzi chazithunzi: Zipangizo za CUI)

Kukonza mawaya: Mofanana ndi kulunjika, pali njira zitatu zodziwika bwino zoyankhira mawaya a ma terminals: ma terminals, mabatani, kapena kukankhira mkati.Magulu onse atatuwa ndi oyenera kutchulidwa.Terminal yokhala ndi ulusi kapena screw-type terminal block imakhala ndi screw yomwe, ikamangidwa, imatseka chotchinga kuti kondakitala atetezeke.The batani ntchito ndi losavuta, ingodinani batani, kutsegula kopanira kulola waya amaika, kumasula batani ndi kutseka kopanira achepetsa waya.Pama block-in terminal blocks, waya amatha kulowetsedwa mwachindunji mnyumbamo ndipo kulumikizana kumatha kukhazikitsidwa popanda screw kapena batani kuti mutsegule chotchinga.
Chithunzi 2: Njira yokhazikika yawaya (Magwero azithunzi: Zipangizo za CUI)

Mtundu wa interlock ndi mtundu umodzi: chipika cha terminal chikhoza kukhala chamtundu wa interlock kapena nyumba yamtundu umodzi.Mipiringidzo yolumikizirana nthawi zambiri imapezeka mumitundu ya 2 - kapena 3-pole, zomwe zimalola mainjiniya kuti akwaniritse manambala osiyanasiyana amitengo kapena kulumikiza mitundu yosiyanasiyana yamtundu womwewo wa module pamodzi.Monomer terminal block mosakayikira mizati yonse ili mu gawo, molingana ndi zofunikira za mapangidwe, kuti ikhale yolimba komanso yolimba.
Chithunzi 3: Kulumikizana motsutsana ndi midadada yama terminal (Magwero: Zida za CUI)

Waya-to-chipolopolo: Pulagi - mu midadada yotsekera ndi chisankho chabwino cholumikizira pafupipafupi ndikudula cholumikizira chachikulu.Izi zimachitika polowetsa waya mu pulagi yokhazikika kenako ndikulumikiza pulagi ku socket yokhazikika pa PCB, kupangitsa kuti ikhale yosavuta kulumikiza popanda kuthana ndi mawaya amodzi.
Chithunzi 4: Pulagi ndi socket yolumikizira pulagi ndi plug terminal block (Gwero la zithunzi: Zida za CUI)

Miyezo yachitetezo ndi malingaliro ena

UL ndi IEC ndi mabungwe akuluakulu achitetezo otsimikizira midadada yama terminal.Miyezo yachitetezo ya UL ndi/kapena IEC nthawi zambiri imalembedwa m'magawo a terminal, ndipo ma parameter nthawi zambiri amasiyana.Izi ndichifukwa choti makina aliwonse amagwiritsa ntchito mayeso osiyanasiyana, chifukwa chake mainjiniya ayenera kumvetsetsa zofunikira zachitetezo pamakina awo onse kuti asankhe midadada yoyenera.

Ngakhale zinthu zina zitha kukhala zongoganiziridwa m'mapangidwe ambiri, zimalipira kukongoletsa nyumba kapena mabatani a block block.Posankha mitundu yapadera yama block block, mainjiniya amatha kulumikiza mfundo mosavuta pamakina ovuta popanda kuwalumikiza.

Pomaliza, m'malo kapena mapulogalamu omwe akukumana ndi kutentha kwambiri, zotchingira zokhala ndi magiredi okwera amathanso kusankhidwa.
