Ubonakalisa ukhetho lwezinto eziphathekayo, i-screw geometry, kunye neengcamango zolawulo lobushushu eziqhekekayo ukuba indawo yokufaka iyaphambuka kwiimeko zovavanyo. Ndichithe iminyaka ndibukele amaqela okuthenga ekhetha iibhloko zesiphelo ngokusekelwe kwixabiso ngepali nganye ngelixa ndingayinaki imeko yentsimi egqiba ukuba ezo pali ziphila iminyaka emihlanu okanye iinyanga ezintlanu. Umsantsa phakathi kovavanyo lwekhathalogu kunye nokusebenza kwehlabathi lokwenyani kulapho uninzi lokusilela kokusasazwa kuvela khona.

Kutheni i-5.0mm Pitch iyindawo emnandi yokusasazwa kwemizi-mveliso

Ipitshi ye-5.0mm ivele njengesivumelwano. Iipitshi ezincinci azikwazi ukusingatha i-wire gauge okanye uxinano lwangoku olufunekayo ekusasazweni kwamandla. Iipitshi ezinkulu zichitha i-PCB real estate kwaye zonyusa unyawo lwephaneli yokulawula. Kubavelisi abajolise kulawulo lweemoto zoshishino, ukwenziwa kwezinto ngokuzenzekelayo, kunye nee-inverters zamandla avuselelekayo, isithuba se-5.0mm simele ibhalansi phakathi kweemfuno zesithuba sombane kunye noxinano loomatshini. Imigama yokuqhekeka kunye nokususwa kweli pitshi yanele kwiinkqubo ze-1000V phantsi I-IEC 60947-7-1 xa izinto ezisisiseko zilinganiswe ngokufanelekileyo, yiyo loo nto lo mgangatho ujongana ngqo neebhloko zesiphelo sezixhobo zoshishino ezinee-voltage ezilinganisiweyo ukuya kuthi ga kwi-1000V.

Ukuhambelana kweWire Gauge: 14AWG ukuya kwi-10AWG Ngaphandle kokuguqulwa kweZixhobo

Enye inzuzo esebenzayo ye-5.0mm pitch kukuba i-wire range iyakwazi ukuyithwala ngaphandle kokunyanzela umfaki ukuba atshintshe ii-crimping dies okanye ubude be-strip. Uthotho lwee-terminal block olunye lunokuphatha ii-14AWG conductors zezibonakaliso zolawulo kunye nee-10AWG conductors ze-power feeders. Oku kubalulekile kwivenkile. Ukuba ingcali yombane kufuneka ivale iphaneli exutyiweyo ene-signal kunye ne-power wiring, ukusebenzisa usapho lwe-terminal block enye kunciphisa ukusetyenziswa kwezixhobo kunye noqeqesho. Indlela yokwenza i-screw clamp kwi-standard Ibhloko yesiphelo se-PCB yesikrufu se-5.0mm isebenzisa uyilo lwekheji olunyukayo oluphakamisa umqhubi ngokuchasene nomda wangoku njengoko isikrufu siqina. Olu yilo lwamkela ucingo oluqinileyo, ucingo oluxineneyo, kunye nee-conductors ezine-ferruled ngaphandle kwe-adapter inserts, yiyo loo nto i-pitch ye-5.0mm ilawula iiprojekthi zokulungisa apho iintlobo zentambo ezikhoyo zingenakuqikelelwa.

Iimfuneko ze-IEC 60947-7-1 zeCreepage kunye neClearance kwi-1000V

Ukuqhekeka kunye nokususwa kwezixhobo akubonakali. Kwi-1000V, ukuqhekeka phakathi kweepali ezikufutshane kunokutshabalalisa yonke indibano ye-PCB. Ipitch ye-5.0mm inika malunga ne-5mm yomsantsa womoya phakathi kweendawo eziqhubayo, nto leyo eyanelisa iimfuno zokuqhekeka kwesigaba se-III sombane ogqithisileyo kwi-1000V kwiindawo ezicocekileyo. Umgama wokuqhekeka kumphezulu weplastiki mde kuba i-terminal block geometry ibandakanya imiqobo okanye imingxunya enyanzela indlela yokuvuza ukuba ijike. Yingakho abavelisi bechaza inqanaba longcoliseko 2 okanye 3 ratings ngokuxhomekeke kuyilo lwezindlu. Ndibone iiphaneli zifakelwa kwiindawo zezolimo apho ukuqokelelwa kothuli kunciphisa umgama wokuqhekeka osebenzayo kwiminyaka emibini, nto leyo ebangela ukusilela kokulandelela uyilo lokuqala olungazange lulindele. Umgangatho uthatha indawo elawulwayo. Inyani ayisoloko isebenzisana.

Umthamo wangoku we-150A: Isayensi yezinto eziluncedo emva kovavanyo

Ireyithingi ye-150A ayisiyo ngcebiso. Ngumda wobushushu obalwe phantsi kweemeko ezithile: ubushushu obuphakathi obuyi-40°C, ukufakwa komaleko omnye, kwaye akukho mithombo yobushushu ekufutshane. Tshintsha naziphi na ezo zinto kwaye amandla okwenyani ayawa. Ibha yangoku ngaphakathi kwebhloko yesiphelo idla ngokuba yi-brass okanye i-copper alloy, kwaye umahluko wokuqhuba ubalulekile. I-brass alloy enomxholo we-60% we-copper ithwala malunga ne-75% ye-conductivity ye-copper ecocekileyo. Kwi-150A, loo ntsilelo ye-25% iguqulela ekufudumaleni kwe-joule eyongezelelweyo ngaphakathi kwebhloko yesiphelo apho ubushushu bungenakuphela lula. Isikrufu ngokwaso sidla ngokuba yintsimbi ene-zinc plating, eyingxaki yobushushu kuba intsimbi iqhuba ubushushu kakubi xa ithelekiswa ne-copper. Ukunyuka kobushushu kwindawo yoqhagamshelwano phakathi kwentambo kunye ne-current bar kulapho kuqala khona ukungaphumeleli. Imigangatho ye-IEEE kwizixhobo zokusasaza umbane zibonelela ngesikhokelo esongezelelweyo malunga nolawulo lobushushu kunye nokubalwa koxinano lwangoku oluhambelana neenkcukacha zezinto ze-IEC.

Ubhedu vs Ukuqhuba Umzimba weCopper kunye nokuguqulwa koomatshini

I-Brass ilawula ishishini leebhloko zesiphelo kuba itshiza kakuhle, imelana nokugqwala, kwaye ixabisa kancinci kune-copper. Utshintsho lukukuqhuba. Kwi-150A continuous load, i-brass current bar ene-2.5mm cross-section iya kushushu ngakumbi kune-copper bar efanayo. Umahluko awubi yintlekele, kodwa iyaqokelelana. Kwiphaneli eneebhloko zesiphelo ezingamashumi amahlanu ezithwala i-current ephantse yalinganiswa, umthwalo wobushushu oqokelelweyo unokunyusa ubushushu be-internal ambient nge-15°C okanye ngaphezulu, ngokufanelekileyo unciphise ibhloko nganye ngaxeshanye. Ii-copper current bar ziyafumaneka kwi-premium series, kodwa zibiza ngaphezulu kwaye zifuna i-nickel plating ukuthintela i-oxidation. Ukuguquguquka phantsi kwe-screw torque yenye into. I-brass ivelisa i-torque ephantsi kune-copper, oko kuthetha ukuba ukuqina kakhulu kuphazamisa ukubandakanyeka kwentambo kwaye kudala i-loose joint emva kweenyanga ezintandathu. Ndizikrazule iibhloko zesiphelo ezingaphumelelanga apho intambo yentsimbi yayityumkile ngokubonakalayo. Umfakeli usebenzise i-torque efanayo ayisebenzisayo kwiibhloko zentsimbi. Izinto azixoleli loo ngcinga.

Iinkcukacha zeTorque yeScrew kunye neempazamo zokufakelwa kwentsimi

Eyona ndlela ixhaphakileyo yokusilela kwiibhloko zesiphelo se-screw yi-under-torque okanye i-over-torque. I-under-torque ishiya umsantsa phakathi komqhubi kunye ne-current bar. Ukumelana koqhagamshelwano kuyanyuka, ukufudumala kwendawo kukhawulezisa i-oxidation, kwaye i-joint ekugqibeleni iyasilela ngenxa yokufudumala. I-over-torque isusa umsonto, iguqule umqhubi, okanye iqhekeze indlu. Inkcazelo ye-torque eprintiweyo kwiphepha ledatha idla ngokuba yi-0.5 ukuya kwi-0.8 Nm kwiibhloko ze-pitch ze-5.0mm. Uninzi lwabasebenza ngombane abanayo i-screwdriver ye-torque elinganiswe kwi-Newton-meters. Bayaqina ide ivakale iqinile. Eso sigqibo sobuqu asichanekanga malunga nesinye kwisithathu sexesha, ngokusekelwe kuphando lwam olungacwangciswanga lwabasebenzi bokulungisa. Izinga lempazamo yokufakwa kwentsimi yimfihlo engcolileyo yoshishino lweebhloko zesiphelo. Abavelisi bacinga ukuba ukufakwa okugqibeleleyo. Abakhi beepaneli bayazi ngcono.

I-Screw Clamp vs I-Push-In Spring: I-Vibration Trade-Off

Iiterminal zentwasahlobo ezityhalwayo zikhawuleza ukufakwa. Leyo yindlela yazo yonke yokubaluleka. Ukhupha ucingo uze ulutyhale ngaphakathi. Akukho screwdriver, akukho ngxaki ye-torque, akukho ntambo eqhaqhwayo. Itshintshiselwano kumthamo wangoku kunye nokumelana nokungcangcazela. Iicontacts zentwasahlobo zixhomekeke kumandla oomatshini ahlala esetyenziswa yi-spring steel clip eyenziweyo. Loo mandla anele ukufakwa okungaguqukiyo kwiindawo ezilawulwa yimozulu. Kwiiphaneli zolawulo lweemoto zoshishino, ukungcangcazela lutshaba. Iicompressors, iipompo, kunye nee-conveyors zivelisa ukungcangcazela okuqhubekayo okukhathaza intsimbi yentwasahlobo ngokuhamba kwexesha. Amandla oqhagamshelwano ayawohloka. Ukumelana nokuqhagamshelana kuyaphakama. Ekugqibeleni ijoyinti iyasilela. Ukuqiniswa kwesikrufu kugcina amandla oqhagamshelwano ngokucinezelwa koomatshini komqhubi ngokuchasene nebha yangoku. Ijoyinti yesikrufu eqhotsiweyo ngokufanelekileyo ayikhululeki phantsi kokungcangcazela kwe-5g kuba ukungqubana kwintambo kudlula amandla okufuduka okushukumayo. Oku akuyonto ithethwayo. Yiyo loo nto amagumbi ecompressor esasebenzisa iiterminal zesikrufu phantse kuphela.

Ukonga Ixesha Lokungena Nokuzincama Kwamandla Angoku

I-terminal yokutyhala igcina malunga nemizuzwana esi-8 ngocingo xa ithelekiswa ne-terminal yesikrufu. Kwiphaneli eneziphelo ezingama-200, oko kuthetha imizuzu engama-27 yomsebenzi. Kwabakhi beephaneli ezinomthamo ophezulu, ukonga komsebenzi kuyinyani. Kodwa amandla angoku aphantsi. Ii-contacts zasentwasahlobo zinendawo encinci yoqhagamshelwano xa kuthelekiswa noxinzelelo olubanzi lomphezulu we-screw clamp. Kwi-150A, indawo yoqhagamshelwano lwasentwasahlobo kuya kufuneka ibe nkulu kakhulu ukuze kugcinwe uxinano lwamandla akhuselekileyo. Uninzi lwee-terminal zokutyhala ziphuma phezulu kwi-32A okanye kwi-41A ngenxa yesi sizathu. I-pitch ye-5.0mm ene-150A rating ayifumaneki kwimo yokutyhala. I-physics ayikuvumeli oko. I-spring kuya kufuneka ibe nkulu kangangokuba indlu ayisayi kuhambelana nesithuba se-5.0mm. Yiyo loo nto usasazo lwamandla kweli nqanaba langoku luhlala luyindawo yokubethela isikrufu.

Ibhloko yesiphelo sesiphelo se-PCB ye-5.0mm ene-150A rating kunye ne-dual certification idla ngokuba lolona khetho luphela oluhlangabezana nayo yonke imiqathango emine ngaxeshanye. Yiyo loo nto iyinto eqhelekileyo yoluhlu lwezinto ezithengiswayo kubasasazi abakhonza kwimarike yolondolozo lwemizi-mveliso.

FAQ

Yeyiphi igeyiji yentambo ephezulu kwibhloko yesiphelo sephithi ye-5.0mm?

Uninzi lweebhloko zesiphelo se-PCB zepitch eziyi-5.0mm zamkela ukuya kuthi ga kwi-10AWG (6mm²). Ezinye iiseries ezinee-housings ezinde zithwala i-8AWG (10mm²), kodwa uluhlu oluqhelekileyo luyi-14AWG ukuya kwi-10AWG. Jonga iphepha ledatha elithile loluhlu lweentambo.

Ndingayisebenzisa i-ferrules ene-screw terminal blocks?

Ewe. Iiferrule ziphucula umgangatho wokuphela kwee-conductors ezixineneyo kwaye zithintela ukuqhekeka kwee-strand. Indlela yokusebenza ye-screw clamp kwiibhloko ezininzi ze-pitch ze-5.0mm yenzelwe ukwamkela ii-conductors ezixineneyo ngaphandle kokutshintshwa. Ububanzi beferrule kufuneka buhambelane noluhlu lwe-terminal block wire range.

Kutheni ibhloko yam yesiphelo isebenza kakhulu kwi-80A xa ilinganiswe kwi-150A?

Uvavanyo lwe-150A luthatha iimeko ezithile: i-ambient engama-40°C, ukufakwa komaleko omnye, kunye ne-torque efanelekileyo. Ukuba iphaneli ixinene, i-ambient iphezulu, okanye i-torque ayilunganga, amandla okwenyani ayehla. Linganisa ubushushu nge-thermocouple kwindawo yokudibanisa. Ukuba idlula i-45°C ukunyuka ngaphezu kwe-ambient, phanda iimeko zokufakela ngaphambi kokuba ugxeke imveliso.

Ngaba ndifuna isiqinisekiso esiphindwe kabini sokuthumela impahla eMexico?

IMexico iyayamkela imigangatho ye-NOM kunye neyehlabathi. Kwizixhobo zoshishino, kufuneka isiqinisekiso se-NOM, kodwa ibhloko yesiphelo enokwaziwa kwe-UL ingasetyenziswa njengecandelo elivunyiweyo kwindibano eqinisekisiweyo ye-NOM. Imfuneko ethile ixhomekeke kudidi lwemveliso yokugqibela. Nxibelelana nequmrhu lesiqinisekiso sendawo ukuze ufumane isikhokelo esicacileyo.

Yeyiphi i-screwdriver ye-torque endifanele ndiyisebenzise kwiibhloko zesiphelo se-pitch eziyi-5.0mm?

Isikrufulu se-torque esilinganisiweyo esinoluhlu lwe-0.1 ukuya kwi-1.0 Nm sifanelekile. Inkcazelo eqhelekileyo yi-0.5 ukuya kwi-0.8 Nm. Musa ukusebenzisa umqhubi wamandla one-slip clutch ngaphandle kokuba i-clutch ilinganisiwe kwaye iqinisekisiwe, kuba ukungcangcazela okuvela kumqhubi kunokukhulula ii-terminals ezikufutshane.
