Xa kuyilwa iinkqubo zolawulo lwemizi-mveliso, ukhetho lwezinto zoqhagamshelo lombane lunokwenza okanye luphule ukuthembeka kwexesha elide. Phakathi kwezixhumi eziguquguqukayo nezisetyenziswa kakhulu kwi-automation yemizi-mveliso kukho iibhloko zesiphelo ezinokuxhunywa—izinto ezidibanisa ukhuseleko loomatshini lokuphelisa izikrufu kunye nokulula kokutshintshwa kwentsimi engenazixhobo. Sekunjalo ayizizo zonke iibhloko zesiphelo ezinokuxhunywa ezidalwe zilingana, kwaye umahluko phakathi kwesixhumi sephithi se-3.5mm kunye nesixhumi sephithi se-5.08mm ubaluleke ngakumbi kunokuba unokubonakala ekuqaleni. Ukuqonda loo mahluko—kunye nendlela iindlela zokutshixa ezisebenzisana ngayo neendawo ezithambekele ekungcangcazeleni—kubalulekile kuyo nayiphi na injineli okanye ingcali yokuthenga evela kwingcali ethembekileyo. umenzi weebhloko zesiphelo ezinokutsalwa.

Eli nqaku lingena nzulu kwiingcamango zobugcisa, zokusebenza, kunye nezinga lesicelo ezahlula le migangatho mibini yepitch, lihlola ingqiqo yobunjineli engasemva koyilo lwe-lock latch kwiindawo zokungcangcazela, kwaye libonelela ngesakhelo esisebenzayo sokufanisa ukhetho lwe-connector neemeko zoshishino zehlabathi lokwenyani.

Yintoni iTerminal Block Pitch, kwaye kutheni ibalulekile?

Iphithi yebhloko yesiphelo ibhekisa kumgama ophakathi ukuya embindini phakathi koqhagamshelwano olukufutshane. Ngokwendlela esebenzayo, imisela ukuba ungayifaka kangakanani i-PCB (ibhodi yesekethe eprintiweyo) okanye indibano yereyile ye-DIN enonxibelelwano. Iphithi encinci ithetha iisekethe ezingaphezulu kwiindawo ezincinci zezindlu; iphithi enkulu ithetha iindawo ezinkulu eziqhuba umbane, ukulinganiswa kwevolthi ephezulu, kunye nokufakelwa kweentambo ngesandla okulula.

Kwiibhloko zesiphelo ezinokutsalwa, imigangatho emibini ephambili yepitch yile 3.5mm kwaye 5.08mm. La manani awananto ingaqhelekanga—abonakalisa amashumi eminyaka okwenziwa kwemigangatho yemizi-mveliso malunga nomgama wegridi ye-PCB, ukufikelela kwi-screwdriver, kunye nomthamo wokuthwala umbane. I-pitch ye-3.5mm ihambelana nokwandiswa kwegridi ye-PCB ye-0.1-intshi esetyenziswa rhoqo kwiimodyuli zemizi-mveliso ezincinci, ngelixa i-5.08mm ihambelana malunga ne-0.2 intshi—isithuba esibonelela ngemida yoomatshini ekhululekileyo yokufaka intambo ngesandla kwiindawo zekhabhinethi yokulawula.

Umthengisi weebhloko zesiphelo sendlela ezixhunywayo ofanele ukuqwalaselwa nguwe uya kubonelela zombini iintsapho zepitch ukujongana neemfuno zesicelo ezipheleleyo. I-Ningbo J-Guang Electronics (J-Guang) ngomnye wabavelisi abanjalo, evelisa iibhloko zesiphelo sendlela ezixhunywayo kwiintsapho zepitch ze-3.5mm, 5.08mm, kunye nezinye iintsapho zepitch kwiimarike zoshishino zehlabathi. Ukufikelela kuluhlu olubanzi lwemveliso kuthetha ukuba umthengisi unokusebenza njengomthombo omnye weemfuno ezininzi zoqhagamshelo kumatshini okanye kwisityalo, okwenza kube lula ukuthengwa kunye nokunciphisa umngcipheko weentsapho zekhonkco ezingahambelaniyo kwindibano enye.

Iibhloko zesiphelo sePitch eziyi-3.5mm: Uyilo oluQhelekileyo lwezicelo ezixineneyo

Ibhloko yesiphelo sepitch ye-3.5mm yeyona ikhethwayo xa indawo yebhodi iphezulu. Ezi zihlanganisi zincinci zifumaneka rhoqo kwi:

Iimpawu zoMbane nezoMechanical

Kwi-pitch eyi-3.5mm, iindawo ezinqamlezileyo zomqhubi zihlala zilinganiselwe kwi-1.5mm² ephezulu kwintambo eqinileyo okanye ebambekileyo. I-pitch encinci ithintela ububanzi bolwimi loqhagamshelwano lwesinyithi, nto leyo ethintela umthamo wokuthwala umbane—ngokubanzi ukuya kwi-10A–13A kuxhomekeke kumenzi kunye nobushushu be-ambient. Into ethintelayo kubushushu: ujongano loqhagamshelwano luchitha ubushushu kancinci kwiindawo ezincinci, kwaye ukudubaduba kukhaba ngamandla njengoko ubushushu be-ambient bunyuka.

I-geometry yoqhagamshelwano enciphileyo ikwathetha amandla aphantsi entwasahlobo ngomjikelo ngamnye wokufaka, nto leyo enokuchaphazela uzinzo lokumelana noqhagamshelwano lwexesha elide. Kwii-applications zenqanaba lesiginali (ii-24V DC sensor loops, izixhobo ze-4–20mA, kunye nezibonakaliso zedijithali eziphantsi kwamandla), oku akusoloko kuyingxaki. Nangona kunjalo, ngokusasazwa kwamandla, usapho lwe-pitch ye-3.5mm lufikelela kwimida yalo esebenzayo, kwaye ukuzama ukusebenzisa ezi zihlanganisi kwiinxibelelwano ezazingadalelwanga zona yenye yezona zizathu zixhaphakileyo zokusilela kwentsimi okulandelelwa ekukhetheni izihlanganisi.

Izinto ekufuneka ziqwalaselwe malunga nokungcangcazela kwi-3.5mm Pitch

Ngenxa yokuba iibhloko zesiphelo se-pitch eziyi-3.5mm zihlala zifakwa kwiindawo ezixineneyo apho kukho khona ukujikeleza kobushushu kunye nokudlidliza koomatshini, i-latch yokutshixa ayisiyonto inokwenzeka—yinto efunekayo. Ngaphandle kokubandakanyeka okuhle, iplagi inokusebenza iphume kwi-header phantsi kokudlidliza okungapheliyo okungapheliyo, okukhokelela kwiisekethe ezivulekileyo kunye nokusilela kwentsimi okubizayo.

I-J-Guang ijongana nale nto ngokuhlanganisa i-dual-point locking latch kuluhlu lwayo lwe-3.5mm pluggable series: i-latch point enye phezulu komzimba we-plug edibanisa i-header shroud, kunye ne-wire entry guard yesibini ecinezela i-conductor xa i-screw i-torqued. Olu gcino lwezigaba ezibini lunciphisa amandla okurhoxisa i-plug kakhulu xa kuthelekiswa noyilo olungabotshwanga, lugcina ukuthembeka konxibelelwano nangaphantsi. Iiprofayili zokungcangcazela ze-sinusoidal ze-EN 60068-2-6 Ukukhawulezisa ukuya kuthi ga kwi-15g. Indlela ye-dual-point isebenza ngokukodwa kuba ijongana namandla okukhupha i-axial (imo yokusilela ephambili ekungcangcazeleni) kunye namandla okukhupha intambo anokuvela kwiimpazamo zolawulo lwentambo ngexesha lokufakwa okanye inkonzo.

Ibhloko yesiphelo sendlela eyi-5.08mm: Ukusebenza okuqinileyo kwizicelo zamandla kunye nezemizi-mveliso

Usapho lwepitshi oluyi-5.08mm lunyuka phantse kuzo zonke iimetrikhi zoomatshini nezombane. Ngomgama wepitshi omalunga ne-45% ngaphezulu, ezi zihlanganisi zithwala iinxalenye ezinkulu zentambo, zibonelela ngemilinganiselo ephezulu yamandla ombane, kwaye zibonelela ngeqonga elikhulu leemetrikhi zezipringi zoqhagamshelwano kunye nezinto zezikrufu. Indawo eyongezelelweyo ayisiyonto nje yokuthuthuzela—imalunga nokuvumela ubunjineli obuqinileyo kwiindawo ezixineneyo.

Iimeko eziphambili zesicelo seebhloko zesiphelo ezinokutsalwa ngephimbo le-5.08mm ziquka:

• Iziphelo zombane apho umbane udlula oko izihlanganisi zepitch eziyi-3.5mm zinokukuphatha ngokukhuselekileyo
• Iindawo zoqhagamshelo lweemoto kwiikhabhathi zolawulo, kuquka izigaba zokukhupha i-VFD (variable frequency drive) kunye neesekethe ezithambileyo zokuqalisa
• Iibhloko zokusasazwa kwesitimela se-DIN apho isixhumi sisebenza njengolawulo lwentambo kunye nendawo yokudibanisa intsimi yeebhasi zamandla
• Ii-inverters zoshishino kunye neenkqubo zokuqhuba, ingakumbi kwizicelo ezifuna ukuthotyelwa kwemvume ye-UL 508A
• Iiphaneli zolawulo lwe-process automation apho ukuthembeka kungaxoxiswananga khona kwaye iimfuno zenkonzo zifuna izihlanganisi ezixhunywayo

Iimpawu zoMbane nezoMechanical

Kwi-pitch ye-5.08mm, i-J-Guang's standard offer ixhasa ubungakanani be-wire ukuya kuthi ga kwi-2.5mm² (kunye noqwalaselo oluthile olufikelela kwi-4mm²), okuvumela ukulinganiswa kwangoku kwe-15A–24A kuxhomekeke kuqwalaselo kunye nee-curves eziqhekekayo. I-pitch ebanzi ibonelela nge-contact interface enkulu, ethetha ngokuthe ngqo ukuba i-contact resistance yokuqala iphantsi kwaye i-thermal dissipation ingcono ngaphakathi kwe-cabinet. I-contact resistance ephantsi ithetha ukuba i-self-heat incinci kwindawo yokudibana, nto leyo ethetha ukuba i-connector isebenza ngaphantsi komda wayo wobushushu, nto leyo enegalelo kubomi benkonzo ende.

Kwizicelo ezifuna i-voltage ephezulu, ukwanda kwemigama yokuqhekeka kunye nokwahlulwa kweendawo ezinxulumene nesithuba se-5.08mm kudla ngokubangela ukuba i-voltage ifikelele kwi-300V (xa ithelekiswa ne-150–200V eqhelekileyo kwi-3.5mm pitch). Oku kwenza usapho lwe-5.08mm lube lolona khetho lwendalo uqhagamshelo lwe-mains-voltage ngaphakathi kweendawo zokuvala zoshishino, ingakumbi apho uyilo lweebhloko ze-PCB screw terminal block kufuneka luhlangabezane neemfuno ze-IEC 60947-1 zokuqhekeka kunye nokususwa kwezinto ukuze kugqunywe ubushushu obusebenzayo.

I-Locking Latch kwiindawo zokungcangcazela: Inyani yoBunjineli

Ukungcangcazela lutshaba loqhagamshelo olukhululekileyo, kwaye iindawo zoshishino—iicompressors, ii-conveyor drives, iinkqubo ze-hydraulic, kunye noomatshini abajikelezayo—zivelisa ukungcangcazela kwi-wide frequency spectrum. Umceli mngeni kuye nawuphi na umenzi weebhloko zesiphelo ezinokuxhunywa kukugcina unxibelelwano oluthembekileyo phakathi kwesinyithi nesinyithi phantsi kweemeko apho intshukumo phakathi kweplagi kunye nentloko izama ngamandla ukwahlula uqhagamshelo.

Indlela yokutshixa evalayo isebenza njengeyona nto iphambili yokugcina izinto. Kukho iifilosofi ezimbini eziphambili zoomatshini:

Ilatshi yokungqubana: Ukuzibandakanya okuqinileyo okuxhomekeke ekuguquguqukeni kwezinto kunye nokudibana namandla aqhelekileyo ukuze kuthintelwe ukutsalwa. Kulula kwaye akubizi kakhulu, kodwa kulula ukuphumla xa kushukuma rhoqo—ingakumbi kumaqondo obushushu aphezulu apho izinto zendlu yenylon zithambileyo. Iilatshi zokungqubana ziyamkeleka kwizixhobo ezimileyo kwiindawo ezilawulwa yimozulu kodwa ziba yingozi kuyo nayiphi na indlela yokusebenzisa ukujikeleza kobushushu okubalulekileyo okanye ukuvuseleleka koomatshini.

Ilatshi yokutshixa echanekileyo: I-interlock yoomatshini efuna ukwenziwa ngabom (ukukhululwa kweqhosha, i-screwdriver cam, okanye i-twist-lock) ukuze isuswe. Olu luyilo olukhethwayo kwii-applications ezibalulekileyo zokungcangcazela. Iibhloko zesiphelo ze-J-Guang ze-5.08mm ezinokuxhunywa ziquka indlela ye-pawl yokutshixa eqinisekisayo ukumelana namandla okukhupha angaphezulu kwe-50N ngoqhagamshelwano ngalunye, nokuba emva kwemijikelo yobushushu engama-500 phakathi kwe--40°C kunye ne-+85°C. Uyilo lwe-positive-lock lususa ngokupheleleyo imo yokungaphumeleli kokuphumla kwe-creep kuba i-interlock yoomatshini igcina ukubandakanyeka nokuba izinto ezihlala kuyo zithambile.

I-latch yokutshixa ibaluleke kakhulu kwizicelo ze-5.08mm kuba i-pitch enkulu idla ngokuhambelana nomsinga ophezulu. Uqhagamshelo olukhululekileyo kwi-20A luvelisa ubushushu obukhulu kwindawo yokujonga (P = I²R), lukhawulezisa i-oxidation kwaye lunokubangela ingozi yomlilo. Ukudibanisa i-latch yokutshixa eqinileyo kunye namandla aqhelekileyo oqhagamshelwano afanelekileyo akunyanzelekanga ukuba kusetyenziswe izixhobo zoshishino eziqinisekisiweyo ngokhuseleko—yimfuno yokusebenza esisiseko ekufuneka iqinisekiswe ngovavanyo, ingathathwa kwizimangalo zedatha kuphela.
