Ndichithe iminyaka emininzi ndifaka iintambo kwiiphaneli zolawulo lwemizi-mveliso, kwaye ukuba kukho into enye endiyifundileyo, kukuba yonke imizuzu echithwayo xa ndilwa ne-screw terminal elukhuni ichitha umzuzu. Xa ndandiqala ukudibana nayo,Iibhloko zesiphelo sendlela yokutyhala umzila we-DIN, Bendingaqinisekanga — ingaba indlela yokusebenza nge-spring-clamp inokuba njani inokuthenjwa njengoqhagamshelo lwezikrufu oluqinileyo? Emva kweminyaka elishumi elinesibini namakhulu eephaneli, ndingumntu otshintshe i-1000V, kwaye ndifuna ukunichazela ukuba kutheni i-1000V-rated push-in terminal block ngoku iyindlela yam emiselweyo kuyo nayiphi na iphaneli yokulawula apho i-voltage yenkqubo idlula i-400V.

Kweli nqaku, ndiza kuthetha ngezinto ezisisiseko zobuchwepheshe be-terminal block, isizathu sokuba umlinganiselo we-1000V ubaluleke kakhulu kwiindawo zoshishino, inkqubo yocingo engenazixhobo inyathelo ngenyathelo, indlela yokukhetha ibhloko efanelekileyo yoyilo lwephaneli yakho, kunye nemigangatho efanelekileyo elawula ezi nxalenye. Nokuba ungunjineli wombane ochaza iinxalenye zephaneli okanye umakhi wephaneli ofuna ukuphucula umbane, ndicinga ukuba uza kufumana into eluncedo apha.

Yintoni i-DIN Rail Push-In Terminal Block?

AIbhloko yesiphelo sendlela yokutyhala umzila we-DIN sisixhobo soqhagamshelo lombane esifakelwa kwi-DIN rail esemgangathweni (ngesiqhelo yi-35 mm × 7.5 mm okanye 35 mm × 15 mm) kwaye sisebenzisa indlela yentwasahlobo ukuqinisa ukufakwa kweentambo ngaphandle kokufuna i-screwdriver. Uyilo lwe-push-in lune-port encinci yokufakelwa ecaleni kwe-spring clamp - uyayisusa intambo, uyifake ngqo kwi-port, kwaye i-spring ibamba ngokuzenzekelayo i-conductor. Ukukhulula intambo, usebenzisa isixhobo esincinci sokukhulula okanye i-screwdriver ukuze usebenze indlela yokukhulula ecaleni kwe-port yokufakela.

Umahluko ophambili kwizithetheiibhloko zesiphelo se-screw-clamp yindlela yokusebenza yespring-clamp. Kwibhloko yescrew-clamp, ucingo luqiniswa ngokuqinisa isikrufu esibamba umqhubi. Ngokuhamba kwexesha, ukungcangcazela kunye nokujikeleza kobushushu kunokubangela ukuba uqhagamshelo lweskrufu lukhululeke — indlela eyaziwayo yokusilela kwiindawo zoshishino. Iiterminal zespring ezityhalelwa ngaphakathi ziyayisusa le ndlela yokusebenza yokusilela kuba ispring isebenzisa uxinzelelo loqhagamshelwano oluqhubekayo nokuba iimeko zobushushu zinjani na, kwaye akukho sikrufu esinokusikhulula.

I-Ningbo J-Guang Electronics, umenzi owasekwa ngo-2010 ogxile kwiibhloko zesiphelo kunye nezihlanganisi, uvelisa uluhlu lwe Iibhloko zesiphelo sendlela yokutyhala umzila we-DIN kuquka uthotho lwabo lwe-JGTD kunye neentlobo ze-plug-in ze-PCT-211 endizichazileyo kwiiprojekthi ezininzi zephaneli yokulawula. Ifektri yabo iphumelele isiqinisekiso solawulo lomgangatho se-ISO 9001:2008, kwaye iimveliso zabo zinemvume ye-SGS, ROHS, REACH, CE, CQC, kunye ne-UL - oku kundinika ukuzithemba xa ndichaza ezi nxalenye zeephaneli zokuthumela ngaphandle ekufuneka zihlangabezane neemfuno zokuthobela imithetho yamazwe ngamazwe.

Ukuqonda i-1000V Rating: Kutheni Kubalulekile kwiiphaneli zoLawulo lwezeMizi-mveliso

I-voltage elinganisiweyo yebhloko yesiphelo yi-voltage ephezulu isixhobo esinokuyinyamezela ngokukhuselekileyo phantsi kweemeko zovavanyo ezichaziweyo. Kwiiphaneli zolawulo zemizi-mveliso, amanqanaba e-voltage ayahluka kakhulu ngokuxhomekeke kwisicelo:

• I-24V DC / 24V AC: Iisekethe zenqanaba lesignali, iingcingo zesensor, iimodyuli ze-PLC I/O. Ibhloko yesiphelo sendlela enereyithingi ye-600V yanele ngokwaneleyo.
• I-AC engama-230V / 400V: Ii-motor feeders eziqhelekileyo, usasazo lwamandla ngaphakathi kwephaneli. Le yeyona voltage ixhaphakileyo yokusebenza kwiiphaneli zemizi-mveliso, kwaye ibhloko elinganisiweyo ye-600V ukuya kwi-1000V ifanelekile.
• I-AC ye-480V: Iimoto eziqhutywa ngamandla aphezulu, ii-amplifiers ezinkulu ze-servo. Kule nqanaba le-voltage, iimfuno ze-creepage kunye ne-clearance phakathi kwee-conductors ziba zibalulekileyo, kwaye ndisoloko ndichaza ubuncinane be-1000V rating.
• I-AC ye-690V: Iimoto zokuqala ezisindayo kwimizi-mveliso, iibha zebhasi ezidityanisiweyo. Kulapho ke ireyithingi ye-1000V iba yinto ebalulekileyo khona — nantoni na engaphantsi kwereyithingi ye-1000V inobungozi bokukhutshelwa ngaphandle kwenxalenye kunye nokusilela kokulandelela ngexesha lokusebenza kwephaneli.

IUvavanyo lwe-1000V Ibonelela ngomda wokhuseleko omalunga ne-45% ngaphezulu kwe-voltage yokusebenza ye-690V emele umda ophezulu wosasazo oluqhelekileyo lwezigaba ezintathu zemizi-mveliso. Lo mda awuxhomekekanga — uchaza ii-voltage transients, i-peak inrush currents, kunye nesiphumo esiqokelelweyo sokukhupha okungaphelelanga kwiindawo ezingcolisiweyo okanye ezifumileyo. I-IEC 61076-2-101: Umgangatho ka-2012 Kwizihlanganisi ezijikelezayo ze-M12 ezisetyenziswa ekulinganiseni nasekulawuleni inkqubo yemizi-mveliso, zichaza iimfuno zojongano lwekhonkco ezihambelana nomlinganiselo wevolthi yebloko yesiphelo - ngokukodwa, imigama egobileyo, imigama yokwahlulwa, kunye nolungelelwaniso lokufakelwa kwe-insulation olumisela umlinganiselo wevolthi walo naluphi na ujongano lombane oludityanisiweyo kwiphaneli yokulawula.

Into enye endihlala ndiyijonga: umlinganiselo we-voltage kufuneka uchazwe kwi- ubushushu obugciniwe apho iphaneli iza kusebenza khona. Abavelisi abaninzi beebhloko zesiphelo bapapasha ukulinganiswa kombane kwi-23°C, kodwa kwi-55°C ambient (eqhelekileyo kwiindawo ezivaliweyo zemizi-mveliso), ukulinganiswa kombane kunokufuneka kuncitshiswe nge-10% ukuya kwi-20%. Amaphepha edatha kaJ-Guang adla ngokuquka i-derating curve, kwaye ndiyaqinisekisa ukuba ndiyayijonga le meko yendawo ngaphambi kokuba ndigqibezele ukukhetha icandelo.

Ucingo Olungenazo Izixhobo: Inkqubo Yoqhagamshelo Lokungena Inyathelo Ngenyathelo

Inkqubo yokufakela iingcingo kwi-terminal block ilula, kwaye emva kokudibanisa okumbalwa kokuqala, uninzi lwabasebenzi be-panel wire bayifumana ngokukhawuleza kune-screw clamping. Nantsi inkqubo endiyifundisayo kuyo yonke i-panel build:

Inyathelo 1: Khetha ubungakanani bentambo obuchanekileyo

Iibhloko zesiphelo sendlela ezityhalwayo zilinganiswe ngokweegeyiji ezithile zentambo. Kwiibhloko zesiphelo sendlela ezityhalwayo ze-J-Guang ze-PCT-211 series DIN, iibhloko zesiphelo sendlela ezityhalwayo eziqhelekileyoii-conductors eziqinileyo ukusuka kwi-0.5 mm² ukuya kwi-2.5 mm² kwaye ii-conductors ezixineneyo ukusuka kwi-0.5 mm² ukuya kwi-2.5 mm² ngeeferrules. Ndisoloko ndiqinisekisa uluhlu oluchanekileyo lwentambo kwiphepha ledatha lomenzi kuba ezinye iibhloko zokutyhala azizamkeli ii-conductors ze-fine-strand (Class5 okanye Class 6) ezingenazo iiferrules — indlela yentwasahlobo inokucinezela ii-fine strands kwaye inciphise uxinzelelo loqhagamshelwano ngokuhamba kwexesha.

Inyathelo lesi-2: Hluba intambo ibe bubude obuchanekileyo

Ubunzulu bokufakelwa — ubude bomqhubi ongenanto ekufuneka bufakwe — buhlala buphawulwa kwindawo yokugcina iibhloko zesiphelo okanye buchazwe kwiphepha ledatha. Kwiibhloko ezininzi zesiphelo se-DIN rail push-in, ubude be-strip buyi 8 mm ukuya kwi-12 mmNdisebenzisa iseti yesixhobo sokucoca iingcingo esihlengahlengiswayo esinobude obuchanekileyo be-strip kwibhloko ethile endiyidibanisayo, kwaye ndiyaqinisekisa ubude be-strip kuyo yonke ibhetshi entsha yengcingo ekuqaleni kweshifti nganye. Ubude be-strip obufutshane kakhulu bubangela ubunzulu bokufakelwa obungonelanga kunye noqhagamshelo oluxhathisayo kakhulu; i-conductor inde kakhulu, kwaye ivele ngaphandle kwendlu, nto leyo edala ingozi yokutshayiswa.

Inyathelo lesi-3: Faka iWire — Akukho Sixhobo Sifunekayo

Kwizikhonthi eziqinileyo kunye nezikhonthi ezifakwe i-ferruled ngokufanelekileyo, ukufakwa akunazixhobo. Ndibamba ucingo ngesandla esinye, ndifake isiphelo esihluliweyo ngqo kwi-insertion port, ndize ndityhale ndide ndive ukukhululwa kwe-spring resistance njengoko i-wire ihleli kwi-clamp. I-spring mechanism ibamba ucingo ngamandla oqhagamshelwano aqhele ukuba yi-8 N ukuya kwi-15 N ngoqhagamshelwano ngalunye — ngokwaneleyo ukuqinisa ucingo ngaphandle kokonakalisa imicu ye-conductor. Ngenxa yokuba akukho skru yokujika kwaye akukho ngcaciso ye-torque yokuqinisekisa, umgangatho wonxibelelwano uyahambelana nokuba ngubani ofake i-wire panel.

Inyathelo lesi-4: Qinisekisa uQhagamshelo

Emva kokufaka, ndinika intambo nganye uvavanyo lokutsala kancinci — ukutsala ngamandla amalunga ne-5 N ukuya kwi-10 N ukuqinisekisa ukuba i-spring grip iyasebenza. Ngokwamava am, uqhagamshelo olufanelekileyo lokutyhala aluyi kukhululwa phantsi kokuphathwa okuqhelekileyo. Ukuba intambo iphuma ngamandla okukhanya, oko kuthetha ukuba i-wire gauge ikumda woluhlu olulinganisiweyo lwebhloko okanye ubude be-strip alwanelanga.

Inyathelo lesi-5: Ukukhululwa (Xa Kufuneka)

Ukuze ndikhulule intambo kwi-terminal yokutyhala, ndifaka i-screwdriver encinci ethe tyaba (ngokuvamile ububanzi be-2.0 mm ukuya kwi-2.5 mm) kwi-port yokukhulula ecaleni kwe-port yokungenisa, ndityhale ngaphakathi ukuze ndiqalise ukukhululwa kwentwasahlobo, kwaye ngaxeshanye nditsale intambo ngaphandle. Isenzo sokukhulula sithatha malunga nemizuzwana emi-2 ngoqhagamshelo ngalunye — sisakhawuleza kakhulu kunokukhulula i-terminal yesikrufu, nto leyo efuna ukuba i-screwdriver ibekwe kwakhona kwaye iqiniswe xa ixhunywa kwakhona.

Ukuthelekisa i-Push-In kunye ne-Screw-Clamp: Ixesha lokukhetha nganye

Ndizisebenzise kakhulu zombini ezi teknoloji, kwaye ukukhetha phakathi kwe-push-in kunye ne-screw-clamp akusoloko kulula. Nantsi intelekelelo yam esebenzayo ngokusekelwe kumava entsimi:

• Isantya socingo: Ukungena ngokukhawuleza kuyaphumelela ngokucacileyo. Kwiizifundo zexesha elilawulwayo endizenzileyo, ukudibana ngokukhawuleza ngokukhawuleza nge-30% ukuya kwi-40% ngoqhagamshelo xa umntu osebenza ngocingo eqeqeshwa. Inzuzo ibonakala kakhulu kwii-solid conductors kunye nee-ferruled stranded wires - iintlobo zee-wire ezixhaphakileyo kakhulu kwii-control panel zoshishino.
• Ukuthembeka koqhagamshelo: Ii-push-in spring clamps azikwazi ukungcangcazela kwaye zigcina uxinzelelo oluqhubekayo lokudibana nge-thermal cycling. Uqhagamshelo lwe-screw-clamp lunokukhululeka ngokuhamba kwexesha ukuba aluna-torque efanelekileyo. Ngenxa yokuba andinakuqinisekisa ukuba yonke iphaneli eyakhiwe ngumenzi-mveliso wesithathu iya kuba noqinisekiso olufanelekileyo lwe-torque, ndikhetha i-push-in kwiiphaneli eziya kubona i-continuous vibration okanye i-thermal cycling - eyona misebenzi iphambili kwimizi-mveliso.
• Ukuhambelana kohlobo lwentambo: Iiterminal ze-screw-clamp zamkela uluhlu olubanzi lweentambo, kuquka nee-conductors ze-fine-strand ezingena-ferruled. Iibhloko ze-Push-in zifuna ii-ferrules kwi-stranded wire kwiimeko ezininzi. Kwiiphaneli ezisebenzisa ii-conductors ezininzi ze-Class 5 okanye ze-Class 6 eziguquguqukayo ezingenazo ii-ferrules, i-screw-clamp inokuba lolona khetho lusebenzayo.
• Uhlengahlengiso lwentsimi: I-screw-clamp iyaphumelela apha — kwiimeko zasentsimini apho iphaneli inokutshintshwa ziingcali ezinezixhobo ezinqongopheleyo, i-screwdriver isoloko ikhona ngelixa isixhobo sokukhulula i-push-in sisenokungabi njalo. Ndichaza i-screw-clamp yoqhagamshelo olunentambo yasentsimini kwiiphaneli apho ndilindele khona utshintsho oluqhubekayo.
• Ixabiso: Iibhloko zesiphelo ezifakwayo zihlala zibiza ngaphezulu nge-10% ukuya kwi-30% ngebhloko nganye kuneenguqulelo ezifanayo ze-screw-clamp. Kwiphaneli enee-connections ezingama-200, oku kunokongeza i-$200 ukuya kwi-$500 kwixabiso lezinto eziphathekayo - ixabiso elifanelekileyo lesantya socingo kunye neenzuzo zokuthembeka.
