Wopereka Malo Olumikizirana: Kukhazikitsa Kopanda Zida ndi Kusunga Mphamvu ya Ma Panel Owongolera

Ngati mukufuna kampani yogulitsa zinthu zosungiramo zinthu zomwe zimagwiritsa ntchito makina osungira zinthu popanda kugwiritsa ntchito zida, nayi mfundo yofunika kwambiri: Ku Ningbo J-Guang Electronics Co., Ltd., takhala zaka 15 zapitazi tikupanga ma DIN-rail push-in terminal blocks omwe amachotsa screwdriver yonse pamene akupereka mphamvu yokhazikika komanso yopanda kukonza. PCT-211 yathu yokankhira mu terminal block imagwiritsa ntchito makina osindikizira achitsulo chosapanga dzimbiri omwe amapanga mphamvu yolumikizirana ya 32 N mpaka 48 N pa waya uliwonse woyikidwa. — kaya katswiri ali pa nthawi yoyamba ya m'mawa kapena 500th. Chifukwa palibe screw yoti amange, palibe torque yoti atsimikizire, palibe kusuntha kwa calibration kuchokera ku zida zakale, komanso palibe kukonzanso komwe kumachitika chifukwa cha maulumikizidwe osakhazikika omwe amalephera panthawi yoyambitsa ma panel. Kasupe wothira mphamvu kale amalimbitsa kutentha ndi kugwedezeka zokha, chinthu chomwe kulumikizana kwa screw-torque yokhazikika sikungathe kuchita. Mu mayeso athu olowetsa-mphamvu ya fakitale m'magawo 1,000 otsatizana, PCT-211 idasunga kukana kwa kulumikizana pansi pa 3.2 mΩ popanda kuwonongeka koyezeka mu mphamvu ya masika - zotsatira zake timazitsimikizira pa gulu lililonse lopanga. Kuphatikiza uku kwa kukhazikitsa kopanda zida komanso kusunga torque yokhazikika ndichifukwa chake omanga ma control panel m'magawo a njanji, magalimoto, ndi mafakitale nthawi zonse amasankha J-GUANG ngati othandizira ma terminal block kuti agwiritse ntchito mawaya ambiri.

N’chifukwa Chiyani Muyenera Kusankha Kankhirani mu Terminal Block M’malo mwa Ma Connection a Screw-Type a Control Panels?

Kusiyana kwakukulu ndikuti kukankhira mu terminal block kumalowa m'malo mwa torque yodalira anthu ndi makina a spring oyendetsedwa ndi fakitale., kuchotsa chosinthika chachikulu kwambiri pa mtundu wa kutha kwa magetsi. Mu mabuloko amtundu wa screw, kudalirika kwa kulumikizana kumadalira mphamvu ya magetsi yomwe katswiri amagwiritsa ntchito — nthawi zambiri 0.5 Nm mpaka 0.8 Nm ya kondakitala wa 2.5 mm² — ndipo kafukufuku wokhudza mawaya amafakitale nthawi zonse akuwonetsa kuti mpaka 15% ya kutha kwa screw m'mapanelo osonkhanitsidwa m'munda kumagwera kunja kwa zenera la mphamvu ya magetsi lomwe latchulidwa.

Mosiyana ndi zimenezi, ukadaulo wokakamiza umachotsa luso loyika zinthu kuchokera ku luso la wogwiritsa ntchito. Kasupe amalimbikitsidwa kale popanga kuti akhale ndi mphamvu yokwanira yomwe imakwaniritsa zofunikira za IEC 60947-7-1 pa waya wonse (0.14 mm² mpaka 6 mm² pa PCT-211 yathu). Katswiri amangoyika kondakitala yokonzedwa mpaka itakhala, ndipo kasupeyo amagwiritsa ntchito mphamvu yake yolumikizira - nthawi iliyonse, mofanana. Kusasinthasintha kumeneku ndi chifukwa chimodzi chokha chomveka chochokera kwa kampani yopereka ma terminal block yomwe imapanga makina ake a masika mkati mwake., monga momwe J-GUANG amachitira, chifukwa magwiridwe antchito a masika amatsimikiziridwa ndi kapangidwe ka zinthu, kutentha, komanso kulondola kwa magawo — osati chowongolera mphamvu pa benchi logwirira ntchito la wopanga panel.

Ine ndekha ndaona mizere yolumikizirana ya control panel pomwe kusintha kuchokera ku screw-type kupita ku push-in terminal blocks kunachepetsa kulephera kwa first pass kuchoka pa 8.3% kufika pansi pa 0.5%, ndipo nthawi yolumikizirana ya panel ndi 52%. Izi si kusintha kwamalingaliro - zimachokera ku deta yeniyeni yopangira m'malo atatu a makasitomala omwe adasintha pakati pa 2023 ndi 2025.

Kodi Kukanikiza mu Terminal Block Kumapereka Bwanji Kusunga Koyenera kwa Torque?

Kusunga mphamvu ya magetsi mu terminal block si chinthu chomwe mungayang'ane mukakhazikitsa - ndi chinthu chopangidwa ngati chitsulo cha spring. Mosiyana ndi cholumikizira cha screw komwe mphamvu yolumikizira imachepa pamene screw imapumula pansi pa kutentha (chomwe chimadziwika kuti "kupumula kwa embedment"), makina olumikizira masika amasunga mphamvu yake mwa kusintha kwa elasticity ya chinthu chachitsulo chosapanga dzimbiri.

Nayi mfundo ya uinjiniya: Pamene cholumikizira cha screw chamangiriridwa, bolt imatambasulidwa mozungulira kuti ipange mphamvu yolumikizira. Koma ngati waya ikanikiza kapena kugwera pansi pa mutu wa screw - zomwe ma conductors amkuwa amachita mosalephera, makamaka kutentha kwambiri - mphamvu ya bolt imatsika chifukwa kutalika kwa elastic kumakhala kokhazikika. Mosiyana ndi zimenezi, kasupe wokankhira mkati umagwira ntchito pa mtunda wautali woyenda, nthawi zambiri kutalika kwa kasupe kumakhala pakati pa 1.5 mm ndi 2.5 mm. Pamene kondakitala yakhazikika kapena kukanikiza, kasupe amangobwerera mkati mwa malire ake otanuka, kusunga mphamvu yosasinthasintha. Ichi ndichifukwa chake ma terminal blocks okankhira mkati amapambana mayeso a IEC 60947-7-1 okweza kutentha ndi kukula kwa waya kuyambira 0.5 mm² mpaka 4 mm² pomwe ma screw block nthawi zina amalephera pa mayeso omwewo pamene screw siimangitsidwanso pambuyo pa kutentha koyamba — sitepe yomwe omanga mapanelo ambiri amalephera kuchita.

Ku J-GUANG, timatsimikizira kusunga kwa torque kudzera mu mayeso ofulumira a kutentha: ma cycle 200 kuyambira −40°C mpaka +105°C, ndi kukana kwa kukhudzana komwe kumayesedwa pambuyo pa ma cycle 25 aliwonse. Mndandanda wathu wa PCT-211 nthawi zonse umasunga kukana kwa kukhudzana pansi pa 3.2 mΩ panthawi yonse yoyeserera, popanda kusintha koyezeka mu kukula kwa kusiyana kwa masika. Tinafalitsa deta iyi ngati gawo la zolemba zathu zabwino, ndipo kasitomala aliyense akhoza kupempha lipoti la mayeso pamodzi ndi chitsanzo cha oda yawo.

Zimene Muyenera Kuyang'ana Mukamayesa Wogulitsa Push In Terminal Block

Si ogulitsa onse omwe amapereka ma terminal block omwe amawapanga mofanana, ndipo kusiyana kwake n'kofunika - makamaka pamene ma control panel anu akufunika kuvomerezedwa ndi UL 508A kapena kutsatira IEC 60204-1. Kutengera ndi zomwe ndakumana nazo poyesa ogulitsa ku China, Europe, ndi Southeast Asia, nazi mfundo zisanu zomwe ndikupangira magulu ogula zinthu kuti aziika patsogolo:

Choyamba, onetsetsani kuti wogulitsayo akupanga okha ma connectors a spring mkati mwa kampani m'malo mogula ma inserts a generic. Tinayika ndalama mu mzere wathu wolondola wosindikizira masika a PCT-211 chifukwa mawonekedwe a mphamvu yolumikizirana amatanthauzidwa ndi mawonekedwe a kasupe, makulidwe a zinthu, ndi chithandizo cha kutentha - kulekerera komwe ogulitsa ochokera kunja samakhala nako nthawi zambiri mpaka ± 0.03 mm. Kupatuka kwa 0.05 mm mu kusiyana kwa kasupe kumatha kusintha mphamvu yolowetsa ndi 15%, zomwe zimakhudza mwachindunji zomwe ogwiritsa ntchito akukumana nazo (kutopa kwambiri kwa mphamvu yaukadaulo) komanso kudalirika kwa kukhudzana.

Chachiwiri, tsimikizirani kuti njira yokankhira zinthu yayesedwa motsatira IEC 60947-7-1 ndi UL 1059, osati "yongopangidwira kutsatira." Timatumiza gulu lililonse la opanga — osati zitsanzo zokha — ku IEC 60947-7-1 Kuyesa kwa anthu ena kuti aone ngati kutentha kwakwera, mphamvu ya dielectric, komanso kupirira kwa makina kuli koyenera. Lipotilo la mayeso likupezeka pa pempho lililonse la kasitomala.

Chachitatu, fufuzani momwe woperekayo amakhudzira waya. Kufunika kwakukulu kwa ogulitsa ma terminal block kuyenera kuphimba kuyambira 0.14 mm² (AWG 26) mpaka osachepera 6 mm² (AWG 10) kudutsa mzere wawo wa DIN-rail. Mndandanda wathu wa PCT-211 umaphimba mtunda uwu m'lifupi mwa nyumba imodzi ya 5.2 mm, ndi mitundu yosiyanasiyana ya imvi (yolowera), buluu (yogawa mbali zonse), ndi wobiriwira-wachikasu (yopanda nthaka).

Chachinayi, funsani za njira zopakira ndi kulemba. Timapereka chizindikiro cha laser, ma CD a tepi ndi reel kuti tigwirizane ndi makina, komanso chizindikiro chachinsinsi cha zilembo — zomwe ndizofunikira mukaphatikiza mabuloko mu chinthu chokhazikika chowongolera.

Chachisanu, pemphani lipoti la mayeso a kugwedezeka. Wopereka chithandizo chapadera ayenera kukhala ndi chidziwitso choyesera cha chipani chachitatu pa IEC 60068-2-6 kapena zofanana. Mu mayeso athu, PCT-211 spring-clamp imasunga kupitiliza kwa magetsi pansi pa 5 g sinusoidal vibration kuyambira 10 Hz mpaka 150 Hz, popanda kulankhulana kapena kutseguka kwakanthawi. Ichi ndi chofunikira chomwecho chomwe chafotokozedwa pazida zolumikizira njanji - chizindikiro chomwe chimalekanitsa ma terminal blocks a grade component ndi ma grade a mafakitale.

Mfundo yofunika kwambiri: Ndikamayang'ana ogulitsa makasitomala athu omanga mapanelo, nthawi zonse ndimanena kuti ogulitsa ma terminal block ndi abwino ngati kasupe wawo — china chilichonse (nyumba, kulemba chizindikiro, kulongedza) chikhoza kupezeka, koma kasupe ndiye mtima wa chinthucho. Ngati wogulitsa sakulamulira kupanga kwawo kwa masika, mulibe chitsimikizo chakuti magwiridwe antchito osungira omwe adagwira ntchito mu prototype adzabwerezanso mu dongosolo lonse la kupanga.

Kodi Kusunga Nthawi Yochuluka Motani Mu Ma Terminal Blocks Mu Control Panel?

Kusunga nthawi kuchokera ku mawaya opanda zida sikungowonjezera nthawi - kukuwonetsa kusintha kwakukulu pakuyenda bwino kwa makina, ndipo manambalawa akuwonetsa izi m'magawo angapo odziyimira pawokha. Malo olumikizirana a Phoenix Contact zalembedwa kuti zikhale zosavuta kwambiri pamakina olumikizirana mawaya, ndipo kufananiza kodziyimira pawokha kumafotokoza kuti ma terminal olumikizirana amatha kuchepetsa nthawi yolumikizirana mawaya ndi 40% poyerekeza ndi ma terminal okhala ndi masika. Ma Aositerminals ikutsimikiziranso kuti m'mapanelo anzeru owunikira nyumba, ma terminal olowetsa magetsi amachepetsa nthawi yolumikizira mawaya ndi pafupifupi 40%.

Ndiloleni ndikupatseni chitsanzo chenicheni kuchokera kwa kasitomala amene timagwira naye ntchito. Kampani yopanga ma control panel aku Europe yomwe imasonkhanitsa ma panel 600 pamwezi, iliyonse yokhala ndi ma terminal a DIN-rail okwana 180, inasintha kuchoka pa screw-type kupita ku ma block athu a PCT-211 push-in kumayambiriro kwa chaka cha 2024. Asanasinthe magetsi, gulu lawo la akatswiri 12 linkagwiritsa ntchito maola 2.8 pa gulu lililonse poyesa kulumikiza magetsi ndi kutsimikizira mphamvu ya magetsi. Pambuyo pa kusinthaku, gulu lomwelo linkafunika maola 1.2 - kuchepetsedwa ndi 57%. Kusunga nthawi kunachokera ku kusintha kutatu: kusagwiritsa ntchito screwdriver pa nthawi iliyonse yomaliza (kusunga masekondi 12 pa waya uliwonse pa avareji), palibe njira yotsimikizira mphamvu (kusunga masekondi 8 pa waya uliwonse), ndipo palibe kukonzanso kuchokera ku maulumikizidwe otayirira omwe adapezeka panthawi yowunikira QC (kusunga avareji ya mphindi 18 pa gulu lililonse).

Pa ma panel 600 pamwezi, kasitomalayo adapeza maola ogwira ntchito pafupifupi 960 pamwezi. — zofanana ndi kuwonjezera akatswiri asanu ndi mmodzi ogwira ntchito nthawi zonse popanda kulemba ntchito aliyense. Kwa wopanga mapanelo omwe amayang'anira malire ochepa, ziwerengerozi sizongoyerekeza za magwiridwe antchito okha; zimakhudza mwachindunji phindu ndi mphamvu yotumizira.

Ndingawonjezere chenjezo apa: ndalama zomwe zasungidwa zikuganiza kuti kapangidwe ka panel kamagwiritsa ntchito ma conductor olimba kapena mawaya osweka omwe ali ndi ma ferrule. Ngati malo anu amagwira ntchito makamaka ndi mawaya osweka opanda ma ferrule, muyenera kuwonjezera sitepe yotsekereza ma ferrule, yomwe imachotsa pang'ono nthawi yomwe ikuwonjezeka. Mu malo osakanikirana mawaya, nthawi zambiri timawona kusunga nthawi yokwanira 40% mpaka 50% m'malo mwa 60%+ yomwe ingatheke ndi mawaya opangidwa ndi mawaya onse. — akadali ofunika, koma ndi koyenera kuganizira mu kusanthula kwanu kwa ntchito.

Kodi Ukadaulo Wokakamiza Umagwira Ntchito pa Ma Circuits Olamulira Amphamvu Kwambiri?

Inde, koma pokhapokha ngati wogulitsa magetsi ofunikira apanga njira yoyenera yonyamulira magetsi — ndipo vuto la uinjiniya si kasupe koma bala lamagetsi ndi kasamalidwe ka kutentha. Mndandanda wathu wa PCT-211 uli ndi ma 24 A pa 800 V ndi kondakitala wa 2.5 mm² (32 A ndi 4 mm²), womwe umaphimba ma signal ambiri a panel yowongolera ndi ma power circuits ambiri. Pa ntchito zogwiritsa ntchito mphamvu zamagetsi zambiri, timagwira ntchito ndi makasitomala kusankha mabuloko oyenera okhala ndi ngalande zazikulu zoyendetsera magetsi ndi mipiringidzo yayikulu yamagetsi., nthawi zambiri mpaka 125 A pogwiritsa ntchito ma conductor a 35 mm².

Chida chofunikira kwambiri chopangira ma block opondereza amphamvu kwambiri ndi kukana kwa ma interface pakati pa kukhudzana kwa kasupe ndi bala lamagetsi. Mu block yopondereza, mutu wa screw umakanikiza kondakitala mwachindunji motsutsana ndi bala, ndikupanga mawonekedwe achitsulo ndi chitsulo okhala ndi kukana kochepa - nthawi zambiri 0.1 mΩ mpaka 0.3 mΩ. Mu block yopondereza, kuthamanga kwa kasupe kuyenera kukhala ndi kukana kofanana kwa ma interface pogwiritsa ntchito mphamvu ya kasupe yokha, popanda ubwino wa makina ngati screw yolumikizidwa. Ichi ndichifukwa chake PCT-211 yathu imagwiritsa ntchito bala lamagetsi la mkuwa lopangidwa ndi zitini lophatikizidwa ndi kasupe wachitsulo chosapanga dzimbiri womwe umapanga mphamvu yolumikizira yosachepera 32 N pa kondakitala aliyense. — yokwanira kukwaniritsa kukana kwa mawonekedwe osakwana 0.15 mΩ popanga, motsatira zomwe IEC 60947-7-1 imafuna za ≤ 3.2 mΩ kukana konse kwa dera.

Timatsimikiza izi pa gulu lililonse lopanga pogwiritsa ntchito waya wa micro-ohmmeter wa 4-wire, ndipo index yathu ya process capability (Cpk) yotsutsana ndi kukhudzana nthawi zonse imakhala pamwamba pa 1.33 - zomwe zikutanthauza kuti 99.99% ya mayunitsi opanga amakwaniritsa zomwe zafotokozedwazo. Ngati mukufuna ma terminal blocks a ma circuits opitilira 32 A, ndikupangira kuti mukambirane za nthawi yanu yapano komanso yantchito yanu ndi gulu lathu la mainjiniya., chifukwa momwe kutentha kumagwirira ntchito zimasiyana malinga ndi mpweya wolowera m'chipinda ndi kulumikizidwa kwa conductor, zonse ziwiri zimakhudza kupotoka kwa curve.

Kumvetsetsa Malo Ovomerezeka a Ma Push In Terminal Blocks

Pamene gulu lanu lowongolera likufunika kupititsa patsogolo UL 508A kapena kukwaniritsa zofunikira pakulemba chizindikiro cha CE, chitsimikizo cha block iliyonse ya terminal chimakhala gawo la unyolo wotsatira malamulo a gululo. Ichi ndi chinthu chomwe ndikugogomezera kwa kasitomala aliyense watsopano: chipika chotsika mtengo kwambiri pamsika ndichokwera mtengo kwambiri ngati chingapangitse kuti gulu lanu lisayang'ane bwino komaliza.

Miyezo yayikulu yomwe imayang'anira ma terminal blocks a ma control panel ndi awa:

IEC 60947-7-1 — Iyi ndi njira yoyesera padziko lonse lapansi ya ma terminal blocks m'mafakitale. Imafotokoza kupirira kwa dielectric (osachepera 2.5 kV), kukwera kwa kutentha (≤ 45 K pamwamba pa mlengalenga pamagetsi ovoteledwa), kupirira kwa makina (≥ ma insertion cycles 50 osalephera), ndi kukana lawi (kuyesa lawi la singano). Wogulitsa ma terminal block aliyense amene amanena kuti akutsatira malamulo ayenera kupereka lipoti loyesa kuchokera ku labotale yovomerezeka.

UL 1059 — Pa ma panel aku North America, UL 1059 ndiye muyezo woyenera. Kusiyana kwakukulu kuchokera ku IEC 60947-7-1 ndikuti UL 1059 imafuna ma voltages okwera a dielectric test ndi magulu ena owonjezera a zoopsa zamoto. Ma block athu a PCT-211 adapangidwa kuti akwaniritse miyezo yonse iwiri nthawi imodzi, ndi nyumba ya PA66 yovotera V0 pa UL 94 kuyesa kuyaka ndi chiyerekezo chofananira chotsata (CTI) cha 600 V.

Kutsatira malamulo a RoHS ndi REACH — Izi ndi zofunika kuti msika wa EU ufike. Ma block a J-GUANG amagwiritsa ntchito zitsulo zamkuwa zophimbidwa ndi tin ndi PA66 popanda zinthu zoletsedwa, ndipo zikalata zotsatizana zimaperekedwa pa oda iliyonse.

Ndaona magulu ogula zinthu akuwononga milungu ingapo akuyesa ogulitsa omwe ma block awo adanena kuti "akutsatira malamulo a IEC" popanda zikalata zotsimikizira mayeso. Malangizo anga: funsani dzina lenileni la labotale yoyesera ndi nambala ya lipoti musanapemphe zitsanzoWopereka chithandizo chapadera adzakhala ndi izi - timasunga laibulale ya malipoti oyesa omwe angapezeke kudzera mu fomu yosavuta yopempha.

Momwe J-GUANG Amafananizira ndi Ogulitsa Ena a Push In Terminal Block

Ndilankhula momveka bwino: pa kuchuluka kwa kupanga kosaphika, J-GUANG ndi yaying'ono kuposa Phoenix Contact kapena Weidmüller. Koma pamapulojekiti apakati a OEM ndi ODM — zidutswa 5,000 mpaka 500,000 pa oda iliyonse — timapereka zabwino zomwe ogulitsa akuluakulu sangafanane nazo.

Timapanga zinthu zosiyanasiyana zomwe zimafunika kukonzedwa bwino, zomwe zikutanthauza kuti zimakhala ndi khalidwe labwino kwambiri pa chiwerengero chilichonse cha zinthu. Pamene wogulitsa wamkulu angapereke ma SKU 50,000 m'mabanja 15 azinthu, PCT-211 ndi PCB screw terminal block yathu 301-5.0 ndizo zambiri mwa zomwe timapanga. Cholinga ichi chimatithandiza kukhala ndi kuwongolera kwambiri njira zathu zogwirira ntchito — mitengo yathu ya Cpk imayesedwa molingana ndi miyezo yabwino kwambiri yamakampani a terminal block, osati kungodutsa "zofunikira" zochepa.

Timapereka mitengo mwachindunji ku fakitale popanda chizindikiro cha ogulitsa m'deralo. Mukagwira ntchito ndi J-GUANG monga wogulitsa zinthu zogulira zinthu zogulira zinthu, mukugula pamtengo womwewo monga wogulitsa zinthu waku Germany amene amagula kuchokera ku kampani ya ku China yotchedwa OEM ndipo amafika pa 25% mpaka 40% pamsika waku Germany. MOQ yathu yokhazikika ndi zidutswa 500 pa nambala ya gawo lililonse, ndi kuchuluka kwa zitsanzo zomwe zikupezeka kuti ziwunikidwe mkati mwa masiku 7 mpaka 10 ogwira ntchito khomo ndi khomo kudzera pa mthenga wachangu.

Timapereka zosintha za OEM zomwe ogulitsa akuluakulu nthawi zambiri amakana. Mukufuna chizindikiro cha mtundu, mtundu winawake wa phukusi la mzere wanu wosankha ndi kuyika, kapena chizindikiro chachinsinsi pakhoma la nyumba? Izi ndi zopempha zomwe timachita nthawi zonse. mzere wonse wazinthu imaphatikizapo ma DIN-rail push-in blocks, ma PCB screw terminal blocks, ndi ma connector solutions ena omwe angasinthidwe malinga ndi kapangidwe ka panel yanu.

Zinthu Zofunika Kuziganizira Posintha Kupita ku Ma Terminal Blocks

Ngati mukuyang'ana kusintha kuchokera ku ma terminal blocks a screw-type kupita ku push-in mu mapangidwe anu a control panel, zinthu zitatu zofunika kuziganizira zidzatsimikizira momwe kusinthaku kudzayendera bwino.

Choyamba, sinthani miyezo yanu yokonzekera waya. Ma block oponderezedwa amagwira ntchito bwino ndi ma conductor olimba kapena ma waya opindika okhala ndi ma ferrule. Ngati miyezo yanu ya mawaya imalola ma conductor opindika opanda kanthu (omwe amafanana ndi ma screw terminals), muyenera kuwonjezera ma ferrule crimping ku BOM yanu ndi akatswiri ophunzitsa kusankha ma ferrule - ferrule iyenera kufanana ndi waya woyezera komanso kukula kwa ngalande ya terminal block. Timapereka chitsogozo chosankha ma ferrule ndi chitsanzo chilichonse kuti kusinthaku kukhale kosavuta.

Chachiwiri, ganizirani za njira yophunzirira. Malinga ndi zomwe takumana nazo, akatswiri omwe akhala akugwiritsa ntchito ma screw terminals kwa zaka zoposa 10 poyamba amakana ma push-in blocks chifukwa "sizimamveka ngati kulumikizana kolimba" popanda kukhudza kwa screw komwe kumangika. Kukana kumeneku nthawi zambiri kumatha mkati mwa milungu iwiri kapena itatu mutagwiritsa ntchito, koma ndi chinthu chenicheni panthawi yoyambitsa. Tikukulimbikitsani kuti muphunzire maola awiri ndi ma sampuli blocks musanasinthe mizere yopangira — Timapereka maphunziro awa kwaulere kwa makasitomala oyamba.

Chachitatu, onetsetsani kuti kapangidwe ka gulu kakugwirizana. Ma block opukutira mkati ali ndi DIN-rail footprint yofanana ndi ma block ofanana ndi screw-type mu rating yofanana ya current - onse amaikidwa pa ma NS 35/7.5 kapena NS 35/15 rails wamba - kotero mapangidwe anu a panel ndi kukula kwa enclosure kumakhalabe kovomerezeka. Kusiyana kokhako kwa kukula kwa block ndi kutalika kwa block: ma block opukutira mkati nthawi zambiri amakhala afupiafupi ndi 2 mm mpaka 4 mm kuposa ma block ofanana ndi screw chifukwa palibe screw tower, zomwe zimapangitsa kuti mpweya upite bwino komanso kuti waya ukhale wopindika mkati mwa enclosure.

Kuchokera pakuwona kwa unyolo wogulira zinthu, kusinthaku ndikosavuta. Mumasintha nambala imodzi ya gawo ndi ina, kusintha malangizo anu ogwirira ntchito, ndipo gawo lonselo — kugawa mphamvu, ma PLC, ma relays, ma contactor — amakhalabe chimodzimodzi. Njira yachangu yotsimikizira izi ndikuyitanitsa zitsanzo za PCT-211 ikankhira mu terminal block kuti pakhale gulu loyesera. Kutumiza kwathu kwa zitsanzo nthawi zambiri kumakhala ndi zidutswa 50 pa nambala iliyonse ya gawo yomwe yapemphedwa, ndipo palinso pepala laukadaulo ndi lipoti loyesera la IEC 60947-7-1.

Malingaliro Olakwika Omwe Amafala Pankhani Yokankhira M'ma Terminal Blocks — Operekedwa

Pambuyo pa zaka zambiri zokambirana ndi omanga mapanelo ndi mainjiniya ogula zinthu, ndimamva nkhawa zomwezo mobwerezabwereza. Nazi malingaliro olakwika omwe amafala kwambiri okhudza ukadaulo wolimbikitsa ndi zenizeni za uinjiniya zomwe zili kumbuyo kwa chilichonse.

Lingaliro Lolakwika 1: "Kulumikizana ndi Push-in sikuli kotetezeka kwambiri kuposa kulumikizana ndi screw." Maganizo olakwika amenewa akupitirira chifukwa chakuti kukhudza kwa screw force kumapangitsa kuti munthu akhale ndi "chitetezo" m'maganizo mwake chomwe push-in block, yokhala ndi single-click insertion, sichichita. M'malo mwake, mphamvu yosungira masika mu push-in block yopangidwa bwino — 32 N mpaka 48 N pa PCT-211 yathu — imaposa mphamvu yomangirira ya screw M3 forced mu mapangidwe ambiri a screw-terminal. Takhala ndi ma conductor ambirimbiri omwe achotsedwa omwe adayesedwa: waya wotchinga umalephera kutulutsidwa masika asanatuluke.

Lingaliro Lolakwika 2: "Ma block opukutira mkati sangathe kuthana ndi kusintha kwa kutentha." Zosiyana ndi zimenezi. Popeza makina a kasupe amalimbana ndi kukulitsa kutentha, ma push-in blocks amachita bwino kuposa ma screw terminals mu mayeso a thermal cycling. Mayeso athu ofulumira okalamba pa 200 cycles kuyambira -40°C mpaka +105°C sakusonyeza kusintha kulikonse koyezeka pa kukana kukhudzana - zotsatira zomwe ma screw terminals amangopeza ngati screw yabwezeretsedwanso pambuyo pa kutentha koyamba.

Lingaliro Lolakwika 3: "Ma block okankhira ndi a ma currents a level signal okha." Mabuloko athu a PCT-211 ali ndi mavoti a 24 A continuous pa 800 V okhala ndi ma conductor a 2.5 mm², omwe amaphimba ma power feed a contactors, motor starters, ndi control transformers m'ma panels ambiri a mafakitale. Pa ma circuit amphamvu okwana 125 A, tikupangira ma block athu akuluakulu opumulirako omwe ali ndi mphamvu ya 35 mm² conductor — izi zimagwiritsidwa ntchito kwambiri pogawa magetsi ndi ma main feeder circuits.

Lingaliro Lolakwika 4: "Ma block oyikamo zinthu amawononga ndalama zambiri kuposa mitundu ya ma screw." Pa gawo la zigawo, chipika chokakamiza nthawi zambiri chimadula 15% mpaka 25% kuposa chipika chofanana ndi screw-type. Koma mukaganizira mtengo woyikidwa — kuphatikizapo ntchito, kutsimikizira mphamvu, kukonzanso, ndi zotsalira za panel — mtengo wonse wa umwini nthawi zambiri umakhala wotsika pa ma push-in blocks. Kutsika kwa 57% kwa makasitomala athu pantchito yolumikizira mawaya kumatanthauza kutsika kwa 32% pa mtengo womaliza pa panel, ngakhale mtengo wokwera wa zigawo.
