Umthengisi weTerminal Block: Ukufakwa okungenazo izixhobo kunye nokugcinwa kweTorque kwiiphaneli zoLawulo

Ukuba ufuna umthengisi we-push in terminal block odibanisa ukufakelwa okungenazixhobo kunye nokugcinwa kwe-torque okuqinisekisiweyo, nantsi eyona nto ibalulekileyo: Apha eNingbo J-Guang Electronics Co., Ltd., sichithe iminyaka eli-15 edlulileyo senza ubunjineli beebhloko ze-DIN-rail push-in terminal ezisusa ngokupheleleyo i-screwdriver ngelixa zinika amandla okubamba ahlala ehleli, angenakulungiswa. I-PCT-211 yethu yokutyhala kwi-terminal block isebenzisa indlela yentwasahlobo yentsimbi engagqwaliyo egxinyiweyo evelisa amandla oqhagamshelwano angama-32 N ukuya kuma-48 N kuyo yonke into yokufaka ucingo. — nokuba ingcali ikwisiphelo sayo sokuqala kusasa okanye kwi-500th. Ngenxa yokuba akukho skrubu yokuqinisa, akukho torque yokuqinisekisa, akukho kushukuma kokulinganisa kwizixhobo ezigugileyo, kwaye akukho kulungiswa okubangelwa kuqhagamshelo olungaguqukiyo olungasebenziyo ngexesha lokufakwa kwepaneli. Intwasahlobo efakwe umfutho ngaphambili ihlawulela ukwanda kobushushu kunye nokungcangcazela ngokuzenzekelayo, into engenakukwazi ukuyenza kuqhagamshelo lwezikrufu olune-fixed-torque. Kwiimvavanyo zethu zokufakelwa kwamandla efektri kwimijikelo eli-1,000 elandelelanayo, i-PCT-211 igcine ukumelana noqhagamshelwano ngaphantsi kwe-3.2 mΩ ngaphandle kokuwohloka okulinganiselweyo kumandla entwasahlobo - isiphumo esisiqinisekisayo kuyo yonke imveliso. Olu qhagamshelo lokufakelwa okungenazixhobo kunye nokugcinwa kwe-torque okuqhubekayo yingakho abakhi beepaneli zolawulo kwicandelo leendlela zikaloliwe, iimoto, kunye nezoshishino bekhetha rhoqo i-J-GUANG njengomthengisi wabo webhloko yesiphelo kwizicelo zeentambo ezinoxinano oluphezulu.

Kutheni Ukhetha i-Push In Terminal Block phezu kwee-Screw-Type Connections kwii-Control Panels?

Umahluko oyintloko kukuba ukutyhala kwi-terminal block kuthatha indawo ye-torque exhomekeke ebantwini nge-spring mechanism elinganiswe ngumzi-mveliso., kususa eyona nto itshintshayo inkulu kumgangatho wokuphela kwento. Kwiibhloko zohlobo lwezikrufu, ukuthembeka koqhagamshelo kuxhomekeke kwi-torque esetyenziswa yingcali — ngesiqhelo ukusuka kwi-0.5 Nm ukuya kwi-0.8 Nm kwi-conductor ye-2.5 mm² — kwaye izifundo kwi-industrial wiring zibonisa rhoqo ukuba ukuya kuthi ga kwi-15% ye-screw terminations kwiiphaneli ezidityaniswe endle ziwela ngaphandle kwefestile ye-torque echaziweyo.

Ngokwahlukileyo koko, iteknoloji yokungena ngaphakathi iyawucombulula umgangatho wofakelo kwisakhono somsebenzisi. Intwasahlobo ifakwa umfutho ngexesha lokwenziwa ukuya kumandla abaliweyo ahlangabezana neemfuno ze-IEC 60947-7-1 kuluhlu olupheleleyo lwe-wire cross-section (0.14 mm² ukuya kwi-6 mm² kwi-PCT-211 yethu). Ingcali ifaka nje umqhubi olungiselelweyo ide ihlale, kwaye intwasahlobo isebenzisa amandla ayo okubamba ayilwe ngawo — ngalo lonke ixesha, ngokufanayo. Olu lungelelwano lolona sizathu sibalulekileyo sokufumana ulwazi kumthengisi weebhloko zesiphelo ovelisa iindlela zakhe zentwasahlobo ngaphakathi., njengoko uJ-GUANG esenza, kuba ukusebenza kwentwasahlobo kuxhomekeka kulwakhiwo lwezinto, unyango lobushushu, kunye nokuchaneka kobukhulu — kungekhona i-torque driver kwibhentshi yokusebenza yomakhi wephaneli.

Ndizibonele ngokwam imigca yokuhlanganisa iiphaneli zolawulo apho ukutshintsha ukusuka kwiibhloko zesiphelo ukuya kwi-push-in terminal kunciphisa izinga lokungaphumeleli kokudlula kokuqala ukusuka kwi-8.3% ukuya ngaphantsi kwe-0.5%, kunye nexesha lokujikeleza kwendibano yeephaneli ngama-52%. Ezi azizophuculo zethiyori - zivela kwidatha yokwenyani yemveliso kuzo zonke izibonelelo zabathengi ezintathu ezenze utshintsho phakathi kowama-2023 nowama-2025.

I-Push In Terminal Block ikwenza njani ukuba ugcine iTorque yokwenyani?

Ukugcinwa kwe-torque kwi-terminal block etyhalelwa ngaphakathi ayisiyonto uyijongayo xa uyifaka — yimpahla ebonakalayo eyilwe ngentsimbi yesipringi. Ngokungafaniyo nesikrufu apho amandla okubamba ehla khona njengoko isikrufu siphumla phantsi kobushushu obuqhelekileyo (into eyaziwa ngokuba yi-"embedment relaxation"), indlela ye-spring-clamp igcina amandla ayo ngokuguqula i-elastic steel stainless spring element.

Nantsi isiseko sobunjineli: Xa i-terminal yesikrufu iqinisiwe, i-bolt yolula ngokuthambileyo ukuze idale amandla okubamba. Kodwa ukuba ucingo luyacinezela okanye luhamba phantsi kwentloko yesikrufu - into engenziwa ngabaqhubi bekopolo, ingakumbi kumaqondo obushushu aphezulu - uxinzelelo lwe-bolt luyehla kuba i-elongation ye-elastic izinzile. Intwasahlobo etyhalwayo, ngokwahlukileyo, isebenza kumgama omde wokuhamba othambileyo, ngesiqhelo isuka kwi-1.5 mm ukuya kwi-2.5 mm yokuphambuka kwentwasahlobo. Xa umqhubi ehlala okanye ecinezeleka, intwasahlobo ijika nje ngaphakathi komda wayo wokunwebeka, igcina amandla ahlala ehleli. Yingakho iibhloko zesiphelo ezityhalelwa ngaphakathi ziphumelela uvavanyo lwe-IEC 60947-7-1 lokunyuka kobushushu kunye nobukhulu beengcingo ukusuka kwi-0.5 mm² ukuya kwi-4 mm² ngelixa iibhloko zezikrufu ngamanye amaxesha ziyasilela kuvavanyo olufanayo xa isikrufu singaqiniswanga kwakhona emva komjikelo wokuqala wobushushu — inyathelo uninzi lwabakhi beepaneli abalitsibayo xa besenza njalo.

Apha e-J-GUANG, siqinisekisa ukugcinwa kwe-torque ngovavanyo olukhawulezileyo lwe-thermal cycling: imijikelo engama-200 ukusuka kwi-−40°C ukuya kwi-+105°C, kunye nokumelana nokudibana okulinganiselweyo emva kwemijikelo engama-25. Uthotho lwethu lwe-PCT-211 luhlala lugcina ukumelana nokudibana okungaphantsi kwe-3.2 mΩ kulo lonke uvavanyo, ngaphandle kotshintsho olulinganisekayo kumlinganiselo wesithuba sentwasahlobo. Sipapashe le datha njengenxalenye yamaxwebhu ethu omgangatho, kwaye nawuphi na umthengi angacela ingxelo yovavanyo kunye ne-odolo yakhe yesampulu.

Yintoni Omele Uyijonge Xa Uvavanya Umthengisi wePush In Terminal Block

Ayizizo zonke iinkampani ezithengisa iibhloko zesiphelo ezizisebenzisayo ezizivelisa ngomgangatho ofanayo, kwaye umahluko ubalulekile — ingakumbi xa iiphaneli zakho zokulawula kufuneka ziphumelele uhlolo lwe-UL 508A okanye zithobele i-IEC 60204-1. Ngokusekelwe kumava am okuvavanya ababoneleli kulo lonke elaseTshayina, eYurophu, naseMzantsi-mpuma Asia, nazi iindlela ezintlanu endicebisa ukuba amaqela okuthenga abeke phambili:

Okokuqala, qinisekisa ukuba umthengisi uzenzela ezakhe izixhobo zokudibanisa iintyatyambo zasentwasahlobo endaweni yokuthenga izinto ezisetyenziswa njengesiqhelo. Sityale imali kumgca wethu wokunyathela ngokuchanekileyo kwizipringi zePCT-211 kuba iprofayili yamandla oqhagamshelwano ichazwa yijiyometri yentwasahlobo, ubukhulu bezinto, kunye nonyango lobushushu — ukunyamezelana okungaqhelekanga ukuba ababoneleli abangaphandle babambelele kwi-±0.03 mm. Ukuphambuka kwe-0.05 mm kwisithuba sentwasahlobo kunokutshintsha amandla okufakwa ukuya kuthi ga kwi-15%, nto leyo echaphazela ngokuthe ngqo amava omsebenzisi (ukudinwa kwamandla agqithisileyo kwingcali) kunye nokuthembeka konxibelelwano.

Okwesibini, qinisekisa ukuba indlela yokutyhala ivavanyiwe ngokwe-IEC 60947-7-1 kunye ne-UL 1059, ayiphelelanga nje "eyenzelwe ukuthobela." Sithumela yonke imveliso — kungekuphela nje iiprototype — I-IEC 60947-7-1 Uvavanyo lomnye umntu olujonga ukunyuka kobushushu, amandla e-dielectric, kunye nokunyamezela koomatshini. Ingxelo yovavanyo iyafumaneka kuyo nayiphi na isicelo somthengi.

Okwesithathu, jonga indlela umthengisi agubungela ngayo uluhlu lweengcingo. Uxinzelelo olukhulu kumthengisi weebhloko zesiphelo kufuneka lugubungele ukusuka kwi-0.14 mm² (AWG 26) ukuya kuthi ga kwi-6 mm² (AWG 10) kumgca wemveliso yabo ye-DIN-rail. Uthotho lwethu lwe-PCT-211 lugubungele olu luhlu kububanzi bendlu enye ye-5.2 mm, kunye neendidi ezinemibala ezingwevu (ezityalwe ngendlela), eziluhlaza okwesibhakabhaka (ezisasazwayo ngendlela engakhethi cala), kunye neziluhlaza-mthubi (ezisemhlabeni).

Okwesine, buza malunga neendlela zokupakisha kunye nokumakisha. Sinikezela ngokumakisha nge-laser, ukupakishwa kwe-tape-and-reel ukuze kuhlanganiswe ngokuzenzekelayo, kunye nophawu lwelebheli lwabucala — amandla abalulekileyo xa udibanisa iibhloko kwimveliso yephaneli yokulawula esemgangathweni.

Okwesihlanu, cela ingxelo yovavanyo lokungcangcazela. Umthengisi weebhloko zesiphelo esifanelekileyo kufuneka akwazi ukubonelela ngedatha yovavanyo lomntu wesithathu ngokwe I-IEC 60068-2-6 okanye into efanayo. Kwiimvavanyo zethu, i-PCT-211 spring-clamp igcina umbane uqhubeka phantsi kwe-5 g sinusoidal vibration ukusuka kwi-10 Hz ukuya kwi-150 Hz, ngaphandle kwengxoxo yokunxibelelana okanye ukuvulwa okungaqhelekanga. Le yimfuno efanayo echazwe kwizixhobo zokubonisa uloliwe - uphawu oluhlulahlula iibhloko zesiphelo secandelo kwizakhiwo zezimboni.

Eyona nto ibalulekileyo: xa ndivavanya ababoneleli ngabathengi bethu abakha iipaneli, ndisoloko ndisithi umthengisi weebhloko zesiphelo ulungile kuphela njengesipringi sabo - yonke enye into (izindlu, ukumaka, ukupakishwa) inokufunyanwa, kodwa isipringi sisentliziyweni yemveliso. Ukuba umthengisi akalawuli ukwenziwa kwentwasahlobo, awunaso isiqinisekiso sokuba ukusebenza kokugcinwa okwasebenza kwiprototype kuya kuphinda kulandelelwe yonke i-odolo yemveliso.

Lingakanani Ixesha Lokuhlanganisa Elinokugcinwa KwiiBloko Zesiphelo Kwiphaneli Yolawulo?

Ukonga ixesha ngenxa yentambo yokuxhuma engenazixhobo akunyuswanga kancinci - kubonisa utshintsho olukhulu kwindlela yokusebenza kwendibano, kwaye amanani abonisa oku kwiindlela ezininzi ezizimeleyo. Iibhloko zesiphelo sePhoenix Contact push-in zibhalwe phantsi ukuze kube lula kakhulu iinkqubo zocingo, kwaye uthelekiso oluzimeleyo luxela ukuba ii-terminals zokufaka umbane zinokunciphisa ixesha locingo ukuya kuthi ga kwi-40% xa kuthelekiswa nee-terminals ezine-spring-loaded. Ii-Aositerminals iqinisekisa ngakumbi ukuba kwiiphaneli zokukhanyisa zekhaya ezikrelekrele, ii-push-in terminals zinciphise ixesha lokufakelwa kweentambo phantse ngama-40%.

Makhe ndikunike umzekelo wokwenyani ovela kumthengi esisebenza naye. Umenzi wephaneli yokulawula yaseYurophu ohlanganisa iiphaneli ezingama-600 ngenyanga, nganye ine-avareji yee-terminals ze-DIN-rail ezili-180, utshintshe ukusuka kwi-screw-type ukuya kwiibhloko zethu ze-PCT-211 push-in ekuqaleni kuka-2024. Ngaphambi kokutshintsha, iqela labo lobuchwephesha abali-12 lichithe umyinge weeyure ezingama-2.8 kwiphaneli nganye ekuqinisekiseni ukufakelwa kwentambo kwisiphelo kunye nokuqinisekiswa kwe-torque. Emva kokutshintsha, iphaneli efanayo yafuna iiyure ezili-1.2 - ukwehla kwama-57%. Ukonga ixesha kuvele kwiinguqu ezintathu ezithile: ukungaphathwa kwesikrudrayivu ngexesha ngalinye lokucima (kugcinwe imizuzwana eli-12 ngocingo ngalunye ngokomndilili), akukho nyathelo lokuqinisekisa i-torque (kugcinwe imizuzwana esi-8 ngocingo ngalunye), kwaye akukho kulungiswa kwakhona kwiiqhagamshelo ezikhululekileyo ezifunyenweyo ngexesha lokuhlolwa kwe-QC (kugcinwe umyinge wemizuzu eli-18 ngephaneli nganye).

Kwiiphaneli ezingama-600 ngenyanga ngokunciphisa ngama-57%, loo mthengi wafumana iiyure zomsebenzi ezingama-960 ngenyanga. — kufana nokongeza iingcali ezintandathu zentambo ezisebenza ixesha elizeleyo ngaphandle kokuqesha mntu. Kumakhi wephaneli olawula iimajini ezincinci, la manani ayizo nje iindlela zokulinganisa ukusebenza kakuhle; achaphazela ngokuthe ngqo inzuzo kunye namandla okuhambisa.

Ndingongeza isilumkiso apha: ezi mali zigcinayo zicinga ukuba uyilo lwephaneli lusebenzisa ii-conductors eziqinileyo okanye iintambo ezifakwe i-ferrule. Ukuba indawo yakho isebenza kakhulu ngeentambo ezifakwe i-fine-stranded ezingenazo ii-ferrule, kuya kufuneka wongeze inyathelo lokuqhekeza i-ferrule, elinciphisa kancinci i-time gain. Kwiindawo ezixutyiweyo, sihlala sibona ukonga ixesha eliyi-40% ukuya kwi-50% kunokuba sibone ukonga ixesha eliyi-60% nangaphezulu ngocingo olune-ferruled. — isebalulekile, kodwa kufanelekile ukuqwalaselwa kuhlalutyo lwakho lomsebenzi.

Ngaba iTekhnoloji yokuThunyelwa kweMishini iyasebenza kwiiSekethe zePhaneli zoLawulo eziKhawulezayo?

Ewe, kodwa kuphela ukuba umthengisi we-push in terminal block uyila indlela yokuthwala umsinga ngokuchanekileyo - kwaye umngeni wobunjineli awusiwo umsinga kodwa yi-current bar kunye nolawulo lobushushu. Uthotho lwethu lwe-PCT-211 lulinganiswe nge-24 A kwi-800 V kunye nomqhubi we-2.5 mm² (32 A ene-4 mm²), ogubungela uninzi lwesignali yephaneli yokulawula kunye neesekethe zamandla. Kwizicelo zamandla aphezulu, sisebenzisana nabathengi ukukhetha iibhloko ezifanelekileyo ezinee-conductor tunnels ezinkulu kunye nee-current bar ezibanzi, ngesiqhelo ukuya kuthi ga kwi-125 A kusetyenziswa ii-conductors ezingama-35 mm².

Ipharamitha yoyilo oluphambili lweebhloko zokutyhala ezinombane ophezulu kukuxhathisa ujongano phakathi koqhagamshelwano lwentwasahlobo kunye nebha yangoku. Kwibhloko yezikrufu, intloko yezikrufu icinezela umqhubi ngqo kwibha, idala ujongano lwesinyithi-kwisinyithi olunokumelana okuphantsi — ngesiqhelo ukusuka kwi-0.1 mΩ ukuya kwi-0.3 mΩ. Kwibhloko yokutyhala, uxinzelelo lwentwasahlobo kufuneka lufikelele kukumelana okulinganayo kojongano kusetyenziswa amandla entwasahlobo kuphela, ngaphandle kwenzuzo yoomatshini yesikrufu esinemisonto. Yingakho i-PCT-211 yethu isebenzisa ibha yamandla e-copper alloy efakwe ngetin edityaniswe nentwasahlobo yentsimbi engenasici evelisa ubuncinci i-32 N yamandla oqhagamshelwano ngomqhubi ngamnye. — yanele ukufikelela kuxhathiso lwe-interface olungaphantsi kwe-0.15 mΩ kwimveliso, ngaphakathi kwemfuneko ye-IEC 60947-7-1 yoxhathiso lwesekethe iyonke ye-≤ 3.2 mΩ.

Siqinisekisa oku kwibhetshi nganye yemveliso sisebenzisa i-micro-ohmmeter ene-wire 4, kwaye isalathisi sethu sobuchule benkqubo (Cpk) sokumelana noqhagamshelwano sihlala singaphezulu kwe-1.33 - oko kuthetha ukuba i-99.99% yeeyunithi zemveliso ziyahlangabezana nemimiselo. Ukuba ufuna iibhloko zesiphelo sesekethe ezingaphezulu kwama-32 A, ndicebisa ukuba uxoxe ngomjikelo wakho wangoku kunye nomsebenzi wakho neqela lethu lobunjineli., kuba ukusebenza kobushushu kuyahluka ngokwendlela umoya ovalekileyo kunye nokubopha i-conductor, zombini ezi zinto zichaphazela i-derating curve.

Ukuqonda iSiqinisekiso seNdawo yeeBloko zeTerminal eziPhushayo

Xa iphaneli yakho yokulawula kufuneka iphumelele uvavanyo lwe-UL 508A okanye ihlangabezane neemfuno zokumakisha ze-CE, ukuqinisekiswa kwebhloko nganye yesiphelo kuba yinxalenye yekhonkco lokuthobela imithetho yephaneli. Le yinto endiyigxininisayo kumthengi ngamnye omtsha: ibhloko yesiphelo ebiza kakhulu kwimarike yeyona ibiza kakhulu ukuba ibangela ukuba iphaneli yakho ingaphumeleli kuhlolo lokugqibela.

Imigangatho ephambili elawula iibhloko zesiphelo ezityhalelwayo kwiiphaneli zolawulo yile:

I-IEC 60947-7-1 — Le yindlela yokulinganisa yehlabathi yeebhloko zesiphelo kwizicelo zoshishino. Ichaza ukumelana ne-dielectric (ubuncinci be-2.5 kV), ukunyuka kobushushu (≤ 45 K ngaphezu kwe-ambient kwi-current elinganisiweyo), ukunyamezela koomatshini (≥ imijikelo yokufakelwa engama-50 ngaphandle kokusilela), kunye nokumelana nelangatye (uvavanyo lwelangatye lenaliti). Nawuphi na umthengisi webhloko yesiphelo otyhalela phambili othi uyathobela kufuneka anike ingxelo yovavanyo evela kwilabhoratri evunyiweyo.

UL 1059 — Kwiifektri zaseMntla Melika, i-UL 1059 ngumgangatho ofanelekileyo. Umahluko ophambili kwi-IEC 60947-7-1 kukuba i-UL 1059 ifuna ii-voltages zovavanyo lwe-dielectric eziphezulu kunye nohlu olongezelelweyo lweengozi zomlilo. Iibhloko zethu ze-PCT-211 zenzelwe ukuhlangabezana nemigangatho yomibini ngaxeshanye, kunye ne-PA66 housing elinganiswe yi-V0 nganye. UL 94 uvavanyo lokutsha kunye ne-comparative tracking index (CTI) ye-600 V.

Ukuthobela iRoHS kunye neREACH — Ezi ziyimfuneko ukuze kufikelelwe kwimarike ye-EU. Iibhloko zesiphelo se-J-GUANG zisebenzisa ii-alloys zobhedu ezifakwe kwi-tin kunye ne-PA66 ngaphandle kwezinto ezithintelweyo, kunye namaxwebhu okuthobela umthetho anikezelwa kwi-odolo nganye.

Ndibone amaqela okuthenga echitha iiveki evavanya ababoneleli abathi "bayawuthobela umthetho we-IEC" ngaphandle kwamaxwebhu ovavanyo axhasayo. Ingcebiso yam: cela igama lelabhoratri yovavanyo kunye nenombolo yengxelo ngaphambi kokuba ucele iisampuluUmthengisi weebhloko zesiphelo ofanelekileyo uya kuba nazo ezi zinto zilungile — sigcina ithala leencwadi leengxelo zovavanyo ezifumanekayo ngefomu yesicelo elula.

Indlela iJ-GUANG ethelekiswa ngayo nabanye ababoneleli bePush In Terminal Block

Ndiza kuthetha ngqo: malunga nomthamo wemveliso eluhlaza, i-J-GUANG incinci kunePhoenix Contact okanye iWeidmüller. Kodwa kwiiprojekthi ze-OEM kunye ne-ODM eziphakathi - iziqwenga ezi-5,000 ukuya kwezi-500,000 nge-odolo nganye - sinikezela ngeenzuzo ezingenakulinganiswa nabathengisi abakhulu.

Senza uluhlu lwemveliso olugxile kwingqwalasela, nto leyo ethetha ukuba umgangatho ophezulu uhambelana nenani lenxalenye nganye. Apho umthengisi omkhulu enokubonelela ngee-SKU ezingama-50,000 kwiintsapho ezili-15 zemveliso, i-PCT-211 kunye ne-PCB screw terminal block yethu 301-5.0 zibangela uninzi lomthamo wemveliso yethu. Olu gxininiso lusenza sikwazi ukugcina ulawulo lwenkqubo oluqinileyo — amaxabiso ethu e-Cpk alinganiswa ngokwemilinganiselo engcono kakhulu kushishino lwe-terminal block, kungekhona nje "ukudlula" ubuncinci beenkcukacha.

Sinikezela ngamaxabiso ngqo emveliso ngaphandle kophawu lokusasaza lwengingqi. Xa usebenza ne-J-GUANG njengomthengisi wakho weebhloko zesiphelo, uthenga ngexabiso elifanayo nomsasazi waseJamani othenga kwi-OEM yaseTshayina aze afumane amanqaku aphezulu ukusuka kwi-25% ukuya kwi-40% kwimarike yaseJamani. I-MOQ yethu esemgangathweni yiziqwenga ezingama-500 ngenombolo yenxalenye nganye, kunye nobungakanani besampulu obufumanekayo ukuze buvavanywe zingadlulanga iintsuku ezisi-7 ukuya kwezili-10 zokusebenza, ungena emnyango nomnyango nge-courier ekhawulezayo.

Sibonelela ngeenkonzo ze-OEM ngokwezifiso ezidla ngokungafunwa ngababoneleli abakhulu. Ngaba ufuna uphawu lombala olucwangcisiweyo, ifomathi ethile yokupakisha yomgca wakho wokukhetha nokubeka, okanye ilebheli yabucala ecaleni kwendlu? Ezi zizicelo zesiqhelo kuthi. umgca opheleleyo wemveliso ibandakanya iibhloko zokutyhala ze-DIN-rail, iibhloko zesiphelo se-PCB screw, kunye nezisombululo ezongezelelweyo zesixhumi ezinokwenziwa ngokwezifiso ngokwesakhiwo sephaneli yakho.

Izinto Ezibalulekileyo Omele Uziqwalasele Xa Utshintshela Kwi-Push In Terminal Blocks

Ukuba uvavanya utshintsho ukusuka kwiibhloko zesiphelo sendlela ukuya kwiibhloko zesiphelo sendlela kuzo zonke iiphaneli zakho zolawulo, izinto ezintathu ekufuneka ziqwalaselwe ziya kugqiba ukuba utshintsho luhamba kakuhle kangakanani.

Okokuqala, hlaziya imigangatho yakho yokulungiselela ucingo. Iibhloko zokutyhala zisebenza kakuhle ngee-conductors eziqinileyo okanye iintambo ezixineneyo ezine-ferrule. Ukuba imigangatho yakho yocingo yangoku ivumela ii-conductors ezingenanto ezixineneyo (ezifana nee-screw terminals), kuya kufuneka wongeze i-ferrule crimping kwi-BOM yakho kwaye uqeqeshe iingcali ekukhetheni i-ferrule - i-ferrule kufuneka ihambelane ne-wire gauge kunye nobubanzi be-tunnel ye-terminal block. Sinikezela ngesikhokelo sokukhetha i-ferrule kuyo yonke i-oda yesampuli ukuze kube lula olu tshintsho.

Okwesibini, jonga indlela yokufunda. Ngokwamava ethu, iingcali ebezisebenzisa ii-screw terminals iminyaka engaphezu kwe-10 ekuqaleni ziyazichasa ii-push-in blocks kuba "azivakali ngathi ziqinile" ngaphandle kokuba i-tactile feedback yokuqinisa i-screw. Olu xhathiso luhlala luphela kwiiveki ezimbini ukuya kwezintathu emva kokusetyenziswa, kodwa yinto ebalulekileyo ngexesha lokuqaliswa. Sicebisa iseshoni yoqeqesho lweeyure ezi-2 kunye nee-sample blocks ngaphambi kokutshintsha imigca yemveliso — Sinikezela olu qeqesho simahla kubathengi abaqalayo.

Okwesithathu, qinisekisa ukuhambelana koyilo lwephaneli. Iibhloko zePush-in zine-DIN-rail footprint efanayo neebhloko ze-screw-type ezifanayo kwireyithingi efanayo yangoku — zombini zifakelwa kwiireyili ze-NS 35/7.5 okanye ze-NS 35/15 eziqhelekileyo — ngoko ke uyilo lwephaneli yakho ekhoyo kunye nobukhulu be-enclosure buhlala busebenza. Umahluko kuphela wobukhulu bubude beebhloko: iibhloko ze-push-in zihlala zimfutshane nge-2 mm ukuya kwi-4 mm kuneebhloko ze-screw ezifanayo kuba akukho nqaba ye-screw, nto leyo ephucula ukuhamba komoya kunye nendawo yokugoba ucingo ngaphakathi kwe-enclosure.

Ngokwembono yothungelwano lokubonelela ngeenkonzo, utshintsho lulula. Utshintsha inombolo yenxalenye enye ngenye, uhlaziye imiyalelo yakho yokusebenza kwendibano, kwaye yonke enye iphaneli — usasazo lwamandla, ii-PLC, iirelayini, iicontactor — zihlala zifana ncamashi. Eyona ndlela ikhawulezayo yokuqinisekisa oku kuku-odola iisampulu zethu I-PCT-211 ityhala kwibhloko yesiphelo ukwakhiwa kwephaneli yovavanyo. Ukuthunyelwa kwethu kwesampulu okuqhelekileyo kubandakanya iziqwenga ezingama-50 ngenombolo yenxalenye nganye eceliweyo, kunye nephepha ledatha lobuchwephesha kunye nengxelo yovavanyo ye-IEC 60947-7-1 ifakiwe.

Iingcamango Ezingachanekanga Eziqhelekileyo Malunga Nokutyhala Kwi-Terminal Blocks — Zijongiwe

Emva kweminyaka ndithetha nabakhi beephaneli kunye neenjineli zokuthenga, ndiva izikhalazo ezifanayo ngokuphindaphindiweyo. Nazi iingcamango ezingaqhelekanga malunga netekhnoloji yokuqalisa kunye nenyani yobunjineli emva kwayo nganye.

Ingcamango ephosakeleyo 1: "Uqhagamshelo lwe-Push-in alukhuselekanga kangako njengoqhagamshelo lwe-screw." Le ngcamango iphosakeleyo iyaqhubeka kuba impendulo echukumisekayo yokuqinisa izikrufu idala ingqiqo yengqondo "yokhuseleko" njengoko ibhloko yokutyhala, enokufakwa kwayo kokucofa kube kanye, ingenalo. Enyanisweni, amandla okugcina intwasahlobo kwibhloko yokutyhala eyilwe ngokufanelekileyo — 32 N ukuya kwi-48 N kwi-PCT-211 yethu — idlula amandla okubamba esikrufu se-M3 esiqinisiweyo kwiindlela ezininzi zoyilo lwe-screw-terminal. Siye savavanya amawaka ee-tranfer eziphelelweyo: i-wire sheath iyasilela ngaphambi kokuba i-spring ikhutshwe.

Ingcamango ephosakeleyo yesi-2: "Iibhloko zokutyhala azikwazi ukumelana nokujikeleza kobushushu." Okuchasene noko kuyinyani. Ngenxa yokuba indlela esebenza ngayo intwasahlobo ihlawula ngamandla ukwanda kobushushu, iibhloko zokutyhala zisebenza ngcono kunee-screw terminals kwiimvavanyo zokujikeleza kobushushu. Uvavanyo lwethu olukhawulezileyo lokwaluphala kwimijikelo engama-200 ukusuka kwi-−40°C ukuya kwi-+105°C alubonisi tshintsho lulinganisekayo ekuchaseni uqhagamshelwano - isiphumo sokuba ii-screw terminals zifezekiswa kuphela ukuba i-screw iqiniswe kwakhona emva komjikelo wokuqala wokufudumeza.

Ingcamango engeyiyo 3: "Iibhloko zokutyhala zenzelwe kuphela imisinga yenqanaba lesiginali." Iibhloko zethu ze-PCT-211 zilinganiswe nge-24 A eqhubekayo kwi-800 V kunye nee-conductors ze-2.5 mm², ezigubungela ukutya kwamandla kwiicontactors, iziqalisi zeemoto, kunye nee-control transformers kwiiphaneli ezininzi zemizi-mveliso. Kwiisekethe zamandla aphezulu ukuya kuthi ga kwi-125 A, sicebisa iibhloko zethu ezinkulu ze-cross-section push-in ezinomthamo we-35 mm² conductor — ezi zisetyenziswa rhoqo kwi-power distribution kunye ne-main feeder circuits.

Ingcamango engeyiyo 4: "Iibhloko zokutyhala zibiza kakhulu kuneentlobo zezikrufu." Kwinqanaba lecandelo, ibhloko yokutyhala idla ngokubiza ngaphezulu kwe-15% ukuya kwi-25% kunebhloko yohlobo lwesikrufu elinganayo. Kodwa xa uqwalasela iindleko ezifakiweyo — kubandakanya umsebenzi, ukuqinisekiswa kwe-torque, ukulungiswa kwakhona, kunye ne-scrap yenqanaba lephaneli — ixabiso lilonke lobunini lidla ngokuba liphantsi kwiibhloko zokutyhala. Ukuncipha kwama-57% kwabathengi bethu kubasebenzi bocingo kuguqulelwe ekuncipheni kwama-32% kwixabiso lokuphelisa iphaneli nganye, nokuba ixabiso lecandelo liphezulu.

Imibuzo ebuzwa qho

Yintoni i-push kwi-terminal block? I-push in terminal block sisixhumi sombane esifakwe kwi-DIN-rail esisebenzisa indlela ye-spring-clamp eqinisiweyo ngaphambili ukubopha iingcingo ngaphandle kokufuna ii-screwdriver okanye izixhobo ze-torque. Ii-conductors eziqinileyo kunye neengcingo ezidityanisiweyo ezinee-ferrules zifakwa ngqo kwiyunithi ye-clamping, apho i-spring isebenza kwaye igcina amandla oqhagamshelwano angaguquguqukiyo.

Ukutyhala kwi-terminal block kufezekisa njani ukugcinwa kwe-torque?
