Izici Zikagesi Nezomshini

Ku-pitch engu-5.08mm, ukunikezwa okujwayelekile kwe-J-Guang kusekela osayizi bezintambo abafika ku-2.5mm² (ngokucushwa okuthile okufinyelela ku-4mm²), okuvumela izilinganiso zamanje ze-15A–24A kuye ngokucushwa kanye nama-curve aqhekekayo. I-pitch ebanzi inikeza isikhombikubona esikhulu sokuxhumana, okuhunyushwa ngokuqondile ekunciphiseni ukumelana kokuqala kokuxhumana kanye nokuhlakazeka okungcono kokushisa ngaphakathi kwendlu. Ukumelana okuphansi kokuxhumana kusho ukuzifudumeza okuncane endaweni yokuhlangana, okusho ukuthi isixhumi sisebenza ngaphansi komkhawulo waso wokushisa, okunegalelo empilweni yesevisi ende.

Ezinhlelweni zokusebenza ezidinga i-voltage ephezulu, ukwanda kwamabanga okuhamba kanye nokwehlukaniswa okuhambisana nesikhala esingu-5.08mm kuvame ukuveza izilinganiso ze-voltage ezifika ku-300V (uma kuqhathaniswa no-150–200V ovamile ku-pitch engu-3.5mm). Lokhu kwenza umndeni ongu-5.08mm ube ukukhetha kwemvelo kwalokhu. ukuxhumeka kwe-mains-voltage ngaphakathi kwezindawo zokuvala zezimboni, ikakhulukazi lapho imiklamo yamabhulokhi esikulufo se-PCB kufanele ihlangabezane nezidingo ze-IEC 60947-1 zokudonsa nokususa izinto zokuvikela ezisebenza kahle.

I-Locking Latch Ezindaweni Zokudlidliza: Iqiniso Lobunjiniyela

Ukudlidliza kuyisitha sokuxhumeka okuxekethile, futhi izindawo zezimboni—ama-compressor, ama-conveyor drive, izinhlelo ze-hydraulic, kanye nemishini ejikelezayo—zikhiqiza ukudlidliza kuyo yonke imvamisa ebanzi. Inselele yanoma yimuphi umenzi we-terminal block oxhumaniswayo ukugcina ukuxhumana okuthembekile phakathi kwensimbi nensimbi ngaphansi kwezimo lapho ukunyakaza okuhlobene phakathi kwe-plug ne-header kuzama ngenkuthalo ukuhlukanisa ukuxhumana.

Indlela yokukhiya iyasebenza njengento eyinhloko yokugcina izinto. Kunezindlela ezimbili ezivelele zokusebenzisa imishini:

I-latch yokungqubuzana: Ukuzibandakanya okuqinile okuncike ekuguquguqukeni kwezinto ezibonakalayo kanye nokuxhumana namandla avamile ukuze kumelwane nokukhishwa. Kulula futhi akubizi, kodwa kuthinteka ekuphumuleni kokukhukhuleka ngaphansi kokudlidliza okuqhubekayo—ikakhulukazi emazingeni okushisa aphezulu lapho izinto zokwakha ze-nylon zithambile khona. Ama-latch okuguquguquka ayamukeleka emishinini emile ezindaweni ezilawulwa yisimo sezulu kodwa aba yimbangela kunoma yikuphi ukusetshenziswa ngokujikeleza kokushisa okunenjongo noma ukuvusa ngomshini.

I-latch yokukhiya okuhle: I-interlock yemishini edinga ukusebenza ngamabomu (ukukhululwa kwenkinobho, ikhamera ye-screwdriver, noma i-twist-lock) ukuze isuswe. Lona umklamo okhethwayo wezinhlelo zokusebenza ezibucayi zokudlidliza. Amabhulokhi e-terminal axhumekayo angu-5.08mm ka-J-Guang afaka indlela ye-pawl ye-positive-lock emelana namandla okukhipha angaphezu kuka-50N ngokuxhumana ngakunye, ngisho nangemva kwemijikelezo yokushisa engu-500 phakathi kuka--40°C no-+85°C. Umklamo we-positive-lock uqeda ngokuphelele imodi yokwehluleka kokuphumula kwe-creep ngoba i-interlock yemishini igcina ukuzibandakanya kungakhathaliseki ukuthi izinto ezihlala kuyo ziyathamba.

I-latch yokukhiya ibaluleke kakhulu ekusetshenzisweni okungu-5.08mm ngoba iphimbo elikhulu livame ukuhlobana nogesi ophezulu. Ukuxhumeka okuxekethile ku-20A kudala ukushisa okukhulu esibonakalayo (P = I²R), kusheshise i-oxidation futhi kungadala ingozi yomlilo. Ukuhlanganiswa kwe-latch yokukhiya eqinile kanye namandla ajwayelekile okuxhumana anele akuyona into ongayikhetha emishinini yezimboni eqinisekisiwe ngokuphepha—kuyisidingo esiyisisekelo sokusebenza okumele siqinisekiswe ngokuhlolwa, hhayi okucatshangwayo ezimangalweni zedatha kuphela.
