Siza kubandakanya idatha yokwenyani evela kumgca wethu wemveliso—njenge Ibhloko yesiphelo se-PCB screw 301-5.0—ukuze sibonise oko kudlulayo noko kungaphumeleliyo. Masiqale ngesiseko: ukuqinisekiswa kwezinto.
1. Isiqinisekiso seMpahla: Ngaphaya kweKhadi eliMthubi le-UL
Amaqela okuthenga awamkeli ikhadi eliphuzi le-UL ngexabiso elibonakalayo. Afuna iingxelo zovavanyo lwezinto ezithile (ii-MTR) kwi-resin lot nganye esetyenziswa kwi-terminal block housing. Kwii-PA66 housings zethu, oko kuthetha ukuqinisekisa umlinganiselo wokutsha kwe-UL 94 V-0 ngedatha yovavanyo lokutsha: ixesha lokutsha emva kwelangabi kufuneka libe ngaphantsi kwemizuzwana eli-10 ngesampuli nganye, kwaye akukho manzi avuthayo anokutshisa isalathisi sekotoni. Sibone abahloli bephepha belahla i-batch kuba i-MTR ibonise i-afterflame yemizuzwana eli-12 kwisampuli enye—nangona umyinge wawuyimizuzwana esi-8. Umgangatho ngowomzekelo ngamnye, hayi umyinge.
Ngaphaya kokutsha, bajonga umxholo wefayibha yeglasi kwi-PA66. I-spec eqhelekileyo yi-30% ±2% yokuzaliswa kweglasi ukuze kuqinisekiswe uzinzo olulinganayo. Abahloli basebenzisa uhlalutyo lwe-thermogravimetric (TGA) ukuqinisekisa oku. Ukuba umxholo weglasi wehla uye kwi-27%, indlu inokugoba ngexesha lokutywinwa kwamaza, okubangela ukungalungelelani kwephini. Sigcina amandla e-TGA angaphakathi ukuqinisekisa kwangaphambili yonke ibhetshi ngaphambi kokuthunyelwa. Kwisinyithi sesiphelo, amaqela okuthenga acela uhlalutyo lwe-spectrographic ukuqinisekisa ukwakheka kobhedu (ngesiqhelo i-C36000 okanye i-C37700) kunye nomxholo wobhedu ongaphezulu kwe-57% kunye nomxholo we-lead ophakathi kwe-1.5% kunye ne-3.5% yokulungiswa komatshini. Sinikezela ngale datha kwi-intanethi yethu. uxwebhu lwemveliso kuyo yonke iodolo enkulu.
Iilabhoratri zangaphandle ezifana Iinkonzo zovavanyo lwezinto ze-UL zisetyenziswa rhoqo ekuqinisekisweni komntu wesithathu. Amaqela okuthenga angacela ingxelo yovavanyo oluvunyiweyo yi-ISO 17025 kwilebhu yomthengisi. Apha e-J-GUANG, sinesatifikethi se-ISO 9001:2015 kwaye sigcina iirekhodi zokulinganisa zonke izixhobo zovavanyo, ezihlolwa ngabaphicothi ngexesha lokuhlolwa kwefektri.
2. Ukuthobela Umlinganiselo Phantsi Kwemayikroskopu: Umthetho we-0.1mm
Uhlolo olunemilinganiselo lulapho uninzi lokuhlolwa kwe-bulk order luba khona khona. Amaqela okuthenga asebenzisa oomatshini bokulinganisa abalungelelanisiweyo (CMM) okanye ii-optical comparators ukujonga ubukhulu obubalulekileyo kubungakanani besampulu yeengcezu ezili-125 ngeqashiso ngalinye (ngokwe-IEC 60512-1). Kwibhloko yesiphelo sepitch ye-5.0mm, ubukhulu obuphambili zezi: isithuba sepitch (5.0mm ±0.2mm), ububanzi bepitch (1.0mm ±0.05mm), ubude obupheleleyo (10.0mm ±0.3mm), kunye ne-hole center offset (≤0.1mm). Sibone abahloli begatya ibhetshi kuba ububanzi bepinch kwiisampulu ezi-3 kwezili-125 bulinganiswe yi-0.94mm—yi-0.01mm kuphela ngaphantsi komda we-spec osezantsi. Ukunyamezelana kuphelele.
Kodwa uphononongo lokwenyani luza kwi-interface yokudibana: ubunzulu bentambo yesikrufu kunye nokuvulwa kwe-wire clamp. Kwimodeli yethu ye-301-5.0, intambo yesikrufu ye-M2.5 kufuneka ibe nobunzulu be-4.0mm ±0.1mm, kwaye ukuvulwa kokungena kwentambo kufuneka kube yi-2.5mm ±0.15mm. Abahloli basebenzisa ii-go/no-go gauges kwezi sheke. Ukuba ubunzulu bentambo abunzulu kakhulu, i-screw ayizukubonelela ngamandla aneleyo okubamba kwintambo ye-14 AWG; ukuba inzulu kakhulu, i-screw inokuphuma ezantsi ize ihlulwe. Siqulunqe itheyibhile yokuthelekisa kwiirekhodi zethu zophicotho-zincwadi ezibonisa amazinga aqhelekileyo okupasa/okusilela:
| Ubukhulu | Umda weSpecial | Izinga lokupasa (Imveliso yethu) | Izinga Lokwaliwa Kweshishini |
|---|---|---|---|
| Isithuba sepitshi | 5.0mm ±0.2mm | 99.8% | 2-5% |

Abahloli bayakuthanda ukubona iitshathi ze-SPC—kubonisa ukuba siyasebenza, asiyiyo impendulo. Ukuze ufumane okungakumbi ngenkqubo yethu yomgangatho, jonga yethu isishwankathelo somgca wemveliso.
3. Uvavanyo loMbane oluphantsi koMthwalo: Ukumelana neDielectric kunye noKuchasana noQhagamshelwano
Amaqela okuthenga awavavanyi nje kuphela iibhloko zesiphelo kubushushu begumbi. Avavanya kumaqondo obushushu aphezulu (85°C iiyure ezili-1000 ngokwe-IEC 60998-2-1) nasemva kokuvezwa kukufuma (95% RH iiyure ezingama-48). Iiparameter ezimbini ezibalulekileyo zombane yi-dielectric ukumelana ne-voltage kunye nokumelana nokuxinana. Kwibhloko yesiphelo elinganiswe yi-300V, uvavanyo lwe-dielectric yi-1500V AC umzuzu omnye ngaphandle kokuqhekeka okanye ukuvuza komsinga odlula i-5mA. Sibone abahloli besebenzisa i-1800V imizuzwana emi-5 njengovavanyo lwe-margin—ukuba ayiphumeleli, yonke indawo iyavalelwa.
Ukumelana nokuchukumisa kulinganiswa kusetyenziswa indlela yeKelvin eneengcingo ezine. I-spec idla ngokuba yi-≤5 milliohms yokuqala, kunye ne-≤10 milliohms emva kwemijikelo yokufakwa/yokurhoxisa engama-50. Kodwa nantsi into ebanjiweyo: amaqela okuthenga ahlala evavanya ngentambo yokwenyani (14 AWG stranded copper) endaweni yepini yokuvavanya, kuba ujongano lwentambo ukuya kwisiphelo sendlela yeyona nto ibalulekileyo ebaleni. Ukuba amandla okubamba izikrufu awanelanga, ukumelana nokuchukumisa kunokunyuka kuye kwi-20 milliohms emva kokujikeleza kobushushu. Sivavanya kwangaphambili yonke ibhetshi ngombane we-10A kwimijikelo eli-1000 ukuqinisekisa uzinzo. Iilabhoratri zangaphandle ezifana Iinkonzo zovavanyo zombane zeTÜV Rheinland Nika ubungqina obuzimeleyo kubathengi ababufunayo.
Olunye uphicotho esilubambe kunyaka ophelileyo lubandakanya iqela lokuthenga elivela kumenzi we-solar inverter. Bazise isixhobo sabo sovavanyo baza benza uvavanyo lwe-dielectric lwe-2000V kwiisampuli ezingama-50. Bonke baphumelele, kodwa baqaphele ukuba umgama wokunyuka kwimodeli yethu ye-301-5.0 wawuyi-6.2mm—ngaphezulu kwe-5.5mm ubuncinci kwi-300V ungcoliseko lwe-2. Loo mda wongezelelweyo usinike isikhundla somthengisi okhethwayo. Uvavanyo lombane alupheleli nje ekuphumeleleni/ekusileleni; lumalunga nokubonisa ukuqina koyilo.
4. Ukunyaniseka kwePlating kunye nokumelana nokugqwala: Inyani yeTyuwa yokutshiza
Iiterminal zebloko zesiphelo zihlala zizezobhedu olufakwe i-nickel, ubukhulu beplating buyi-2-5 microns. Amaqela okuthenga ayakuqinisekisa oku esebenzisa ii-analyzers ze-X-ray fluorescence (XRF). Ukuba umaleko we-nickel ungaphantsi kwe-2 microns, isiphelo sinokubola kwiindawo ezinomswakama ophezulu, nto leyo ekhokelela ekunyukeni kokumelana nokuchukumisa. Sibone abahloli bephepha belahla iqela apho ubukhulu be-nickel obuqhelekileyo babuyi-1.8 microns—nangona i-spec yathi yi-2-5 microns. Umda ophantsi awugqibekanga.
Kodwa uvavanyo lokwenyani yi-salt spray nganye kwi-ASTM B117. Kwiibhloko ze-terminal zemizi-mveliso, iiyure ezingama-48 zokuvezwa kwe-salt spray ngaphandle komhlwa obomvu kumphezulu we-terminal ziqhelekile. Ezinye iinkcukacha zezinga leemoto zifuna iiyure ezingama-96. Siqhuba uvavanyo lwe-salt spray kuyo yonke indawo yemveliso kwaye sinikezela ngengxelo. Ngexesha lophicotho-zincwadi olunye, iqela lokuthenga elivela kwinkampani ye-electronics yaselwandle licele i-salt spray yeeyure ezili-120—siphumelele ngaphandle kokubola, kodwa kuphela kuba inkqubo yethu yokufaka iplating ibandakanya umaleko we-nickel we-3 microns ubuncinci ngaphambi kokugqitywa kwe-nickel yokugqibela. Obo bukhulu bungaphezulu busibiza malunga ne-$0.002 nge-terminal nganye, kodwa kufanelekile ukuvunywa.
Abahloli bajonga nokuba akukho plating adhesion besebenzisa iteyiphu yovavanyo (ASTM D3359). Ukuba kukho na plating flakes, isiphelo siyaliwa. Siphucule ikhemistri yethu yeplating bath ukuqinisekisa ukunamathela, kwaye sibhala phantsi ulwakhiwo lwebhafu kunye nobushushu bayo yonke ishifti. Ukuze ufumane okungakumbi ngenkqubo yethu yeplating, jonga iinkcukacha zobugcisa kwi-intanethi yethu. iphepha lemveliso.
5. Ukuqinisekiswa koPakethe: Asiyobhokisi nje
Ii-odolo ezinkulu zeebhloko ezingama-50,000 zesiphelo zifuna ukupakishwa okuthintela umonakalo ngexesha lokuthunyelwa nokugcinwa. Amaqela okuthenga ahlola ukupakishwa kwezinto ezintathu: ukhuseleko oluchasene nokuma, umqobo wokufuma, kunye nokucushwa koomatshini. Iibhloko zesiphelo ezinee-PA66 housings zi-hygroscopic—ukuba zibekwe kwi->60% RH ngaphezulu kweeyure ezingama-48, zinokufunxa ukufuma kwaye zibangele iziphene zokunyibilikisa (ukugquma) ngexesha lokutywina ngamaza. Abahloli bajonga ukuba ukupakishwa kuquka ibhegi yomqobo wokufuma ene-desiccant kunye nekhadi lesalathisi sokufuma. Ukuba ikhadi libonisa umbala opinki (obonisa i->60% RH), yonke indawo iyaliwa.
Ukulungiswa kwe-cushion ngoomatshini kuqinisekiswa kusetyenziswa uvavanyo lokuwa: ibhokisi yeebhloko zesiphelo iwiswa ukusuka kwi-1.2 yeemitha ukuya kumgangatho wekhonkrithi. Ukuba ngaphezulu kwe-1% yeeyunithi zibonisa izindlu eziqhekekileyo okanye iiphini ezigobileyo, uyilo lokupakisha luyasilela. Sisebenzisa i-foam inserts ezenziwe ngokwezifiso ezinee-cutouts kumqolo ngamnye weebhloko zesiphelo, kwaye siphumelele uvavanyo ngalunye lokuwa kwiminyaka emithathu edlulileyo. Amaqela okuthenga akwajonga ukupakishwa okukhuselekileyo kwe-ESD (ukumelana nomphezulu
Ukubhala ilebheli yenye indawo yokuhlolwa: ibhokisi nganye kufuneka ibe nelebheli enenombolo yenxalenye, ubungakanani, ikhowudi yomhla, kunye nenombolo yelothi. Iibhakhowudi kufuneka zithobele i-GS1-128 kwiinkqubo zokugcina impahla ezizenzekelayo. Sibone abahloli begatya ukuthunyelwa kwempahla kuba ibhakhodi yayingcolile kwaye ayinakuskenwa. Yinkcukacha encinci, kodwa ibalulekile kwimpahla ethwala abantu abaninzi.
6. Amaxwebhu Ukuntywila nzulu: Ukulandeleka ukusuka kwiResin ukuya ekuThunyelweni
