Sechinhu chakajairwa chekubatanidza kune ese mainjiniya, materminal blocks ave achishandiswa kwemakore mazhinji kupa semi-chisingaperi yakachengeteka wiring kune akasiyana maapplication.Terminal block, inozivikanwawo seye terminal block, terminal yekubatanidza, kana threaded terminal, ine modular imba uye insulator inobatanidza waya mbiri kana anopfuura pamwechete.Nekuti iyo yekubatanidza ndeye semi-yechigarire, iyo terminal block inobatsira kurerutsa iyo munda yekuongorora uye kugadzirisa maitiro.Kunyangwe chiri chikamu chakareruka, asi pamberi pekusarudzwa kweiyo terminal block uye mataurirwo ayo ane yekutanga kunzwisisa kana yakanaka.
Iyi nhaurirano ichabata akajairwa materminal block marudzi, akakosha emagetsi uye emuchina kufunga, uye nekupa humwe ruzivo rwekubatsira mainjiniya nekusarudza.
Common configuration
PCB gomo mhando, fenzi mhando uye yakatwasuka-kuburikidza nemhando ndiwo matatu akajairika terminal block mhando mukugadzira.Tafura inotevera inonyora mhando nhatu dzakasiyana uye chikonzero chadzo, kuisirwa, uye kumisikidzwa.
Yakakosha Magetsi mataurirwo
Pane akati wandei akakosha emagetsi maratidziro ekufunga panguva yedhizaini, inovhara zvakajairika terminal block mhando.Kunyanya zvinosanganisira:
Rated current.Kazhinji, iyo yakatarwa inoda kutariswa zvakanyanya mujunction bhokisi dhizaini ndiyo yakayerwa ikozvino.Izvi zvinobva pazvikamu zvitatu: magetsi emagetsi ematerminals, nzvimbo ye-cross-sectional uye kukwira kwekushisa kunoenderana.Paunenge uchisarudza zvivharo zvekupedzisira, zvinokurudzirwa kuti iyo yakatemerwa ikozvino ive inokwana 150% yehukuru hunotarisirwa ikozvino hwehurongwa.Kana iyo yakatemerwa ikozvino yeiyo terminal block isina kunaka uye iyo inoshanda ikozvino yakanyanya, iyo terminal block inogona kupisa uye kukuvadzwa, zvichikonzera matambudziko akakomba ekuchengetedza.
Yakatemerwa voltage: Iyo yakayerwa voltage chikamu cheiyo terminal block inokanganiswa ne spacing uye dielectric simba reimba yayo.Nenzira imwechete iyo yakatemerwa ikozvino inosarudzwa, iyo yakatemerwa voltage yeiyo terminal block inofanira kunge yakakura kupfuura iyo yakanyanya voltage yehurongwa, ichifunga nezve chero voltage inokwira inogona kukanganisa kubatana.
Nhamba yemapango: Huwandu hwemapango inzira yakajairika yekutaridza huwandu hwemaseketi akazvimirira ari muvhavhavhavha.Iyi tsanangudzo inowanzosiyana kubva kune unipolar kusvika ku24.
Spacing: Iyo spacing inotsanangurwa sechinhambwe chepakati pakati pemapango ari padhuze, iyo inotarwa nechiyero chese cheiyo terminal block uye inosanganisira zvinhu zvakaita secreepage chinhambwe, voltage / ikozvino, uye clearance.Mimwe mienzaniso yakajairika yepakati inosanganisira 2.54mm, 3.81mm, 5.0mm, nezvimwe.
Saizi/Rudzi rwewaya: KuNorth America, waya inogamuchirwa kune zvivharo zvekupedzisira iri muAmerican Wire gauge (AWG), iyo inotsanangura saizi yewaya kana geji inogamuchirika kune module kuti ive nechokwadi chekuti waya inokwana mudzimba.Sezvineiwo, mazhinji mabhuraki ekupedzisira ane kushivirira kunogona kugarisa huwandu hwesaizi waya senge 18 kusvika 4 kana 24 kusvika 12AWG.Mukuwedzera kune tambo yegeji, funga nezvemhando yewaya zvichienderana nerudzi rwemodule yakasarudzwa.Waya dzakamonyoroka kana dzakawanda-musimboti dzakanakira materminals ane threaded, nepo single-core waya dzinowanzobatanidzwa nemapush-in terminal blocks.
Yakakosha ma mechanical specifications
Tevere kunouya iyo mechaniki yakatarwa, ine hukama nehukuru hweiyo terminal block, kutaridzika, uye nyore kubata kwekubatanidza mudhizaini.Zvinhu zvakakosha zvema mechanical zvinosanganisira:
Wiring directions: Horizontal (90°), vertical (180°) uye 45° ndiwo matatu anonyanyozivikanwa materminal block directions.Iyi sarudzo inoenderana nekurongeka kweiyo dhizaini uye ndeipi nzira yakanyatsokodzera uye yakanakira wiring.
Mufananidzo 1: Yakajairika terminal block yekutarisa (Mufananidzo sosi: CUI Devices)
Kugadziriswa kwewaya: Zvakafanana nekutarisa, kune nzira nhatu dzakajairwa dzekugadzirisa waya kune zvivharo zvekupedzisira: tambo dzakarukwa, push-mabhatani, kana kusundira mukati.Zvose zvitatu zvezvikamu izvi zvakakodzerwa nezita racho.Terminal ine threaded kana screw-type terminal block ine sikuruu iyo, kana yakasungwa, inovhara chisungiso kuchengetedza conductor kune conductor.Basa rebhatani riri nyore kwazvo, ingo dzvanya bhatani, vhura clip kuti ubvumire waya kuisa, buritsa bhatani uye vhara clip kuti ubatanidze waya.Kune ma-push-in terminal blocks, waya inogona kuiswa yakananga mudzimba uye chinongedzo chinogona kumiswa pasina screw kana bhatani kuvhura mbambo.
Mufananidzo 2: Yakajairika waya yekugadzirisa nzira (Mufananidzo sosi: CUI Devices)
Interlock mhando uye imwechete mhando: terminal block inogona kunge iri interlock mhando kana imwechete mhando imba.Interlocking terminal blocks anowanzo kuwanikwa mu2 - kana 3-pole shanduro, zvichibvumira mainjiniya kuti akurumidze kuwana nhamba dzakasiyana dzemapango kana kubatanidza mavara akasiyana emhando imwe chete module pamwechete.Monomer terminal block hapana mubvunzo kuti mapango ese arimo mumodule, zvinoenderana nezvinodiwa zvekugadzira, kuitira kuti ive nepamusoro kuomarara uye kusimba.
Mufananidzo 3: Kupindirana kurwisa monomer terminal blocks (Kwakabva: CUI Zvishandiso)
Wire-to-shell: Plug - mumaterminal blocks isarudzo yakanaka yekubatanidza kazhinji uye kubviswa kwekubatanidza kukuru.Izvi zvinoitwa nekupinza waya mumodular plug uye wozobatanidza plug kune yakagadzika socket paPCB, zvichiita kuti zvive nyore kudzima pasina kubata newaya dzega.
Mufananidzo 4: Plug uye socket yekubatanidza plug uye plug terminal block (Mufananidzo sosi: CUI Devices)
Mazinga ekuchengetedza uye zvimwe zvinotariswa
UL neIEC ndiwo makuru ekuchengetedza masangano ekusimbisa zvivharo zvekupedzisira.UL uye/kana IEC chengetedzo mazinga anowanzo kunyorwa mumaterminal block maratidziro, uye parameter tsika dzinowanzosiyana.Izvi zvinodaro nekuti imwe neimwe nzira inoshandisa akasiyana bvunzo zviyero, saka mainjiniya anofanirwa kunzwisisa zvinodikanwa zvekuchengetedza zvehurongwa hwavo hwese kuti vasarudze mabhuroki akakodzera.
Nepo zvimwe zvinhu zvingave zvekufungidzira mune akawanda madhizaini, zvinobhadhara kuisa ruvara kugadzirisa imba kana mabhatani eiyo terminal block.Nekusarudza akasarudzika mavara ezvivharo zvekupedzisira, mainjiniya anogona nyore kubatanidza mapoinzi mumasisitimu akaomarara pasina kuabatanidza.
Chekupedzisira, munzvimbo kana maapplication anobata nekupisa kwakanyanya, materminal blocks ane epamusoro tembiricha mamakisi anogona zvakare kusarudzwa.
