Umlinganiselo ofanelekileyo woxinzelelo kwi-High-Current Terminal Crimping | Isikhokelo esipheleleyo

Kwiimeko ezinombane ophezulu ezifana namandla amatsha, ubunjineli bamandla kunye nolawulo lwemizi-mveliso, ukugoba isiphelo sendlela yeyona nkqubo iphambili yokuqinisekisa uqhagamshelo lombane olukhuselekileyo. Izibalo zibonisa ukuba i-35% yemililo yombane ibangelwa kuqhagamshelo lwesiphelo olukhululekileyo okanye olubi. Njengepharamitha ephambili yenkqubo yokugoba, umlinganiselo wokugoba umisela ngokuthe ngqo amandla oomatshini kunye nokuqhuba kombane koqhagamshelo. Eli nqaku lichaza uluhlu olufanelekileyo lomlinganiselo wokugoba, ifomula yokubala, izinto ezichaphazelayo kunye nezinto ezibalulekileyo zokusebenza ezisebenzayo zokugoba isiphelo sendlela, ezinokuthi zisetyenziswe ngoko nangoko.

I. Yintoni iCompression Ratio? Qonda intsingiselo yayo ephambili kuqala

Umlinganiselo woxinzelelo (okwaziwa ngokuba yi-compression rate okanye i-compaction rate) ulinganisa umlinganiselo wotshintsho lwe-conductor cross-sectional area ngaphambi nasemva kwe-crimping, ebonisa ukuqina kokulingana phakathi kwe-conductors kunye nee-terminals. Kukho iindlela ezimbini zokubala eziphambili kushishino.

I-USCAR-21 (Isetyenziswa rhoqo kwiindawo zeemoto kunye namandla, izinga lokucinezelwa)

Umlinganiselo woxinzelelo (%) = 100×(1 - Indawo enqamlezileyo yomqhubi emva kokugoba / Indawo enqamlezileyo yomqhubi oqhelekileyo ngaphambi kokugoba)

Umzekelo: Umqhubi we-50mm² ngaphambi kokuba aqanduselwe unendawo yakhe enqamlezileyo encitshiswe ngama-20% emva kokuba eqanduselwe, kunye nomlinganiselo woxinzelelo we-20%.

I-VW 60330 (Isetyenziswa kakhulu kwimigangatho yaseJamani nakwiindawo zoshishino, umlinganiselo wokuxinana)

Umlinganiselo woxinzelelo (%) = Indawo enqamlezileyo yomqhubi emva kokugoba / Indawo enqamlezileyo yomqhubi oqhelekileyo ngaphambi kokugoba × 100%

Umzekelo: Ukuba indawo yomqhubi we-post-crimp ibandakanya i-80% yendawo yokuqala, umlinganiselo woxinzelelo yi-80%.

 

II. Uluhlu olufanelekileyo lweCompression Ratio lweHigh-Current Terminal Crimping

Iimfuno eziphambili zezicelo zombane ophezulu (ii-copper conductors, 6–400mm²): ukumelana okuncinci kokuthintana, amandla aphezulu okutsalwa, ukumelana okugqwesileyo kobushushu kunye nokumelana nokungcangcazela. Uluhlu olufanelekileyo luyahluka ngokwezinto ezisetyenziswayo kunye nemeko yokusebenza.

Amandla okutsala angonelanga, angaphantsi kwama-80% exabiso eliqhelekileyo, athambekele ekukhululekeni nasekuweni xa kungcangcazela.

Izikhewu ezinkulu zivumela ukungena komswakama kunye nothuli, nto leyo ekhawulezisa ukubola kunye nokugqwala.

✅ Umlinganiselo woxinzelelo oluphezulu kakhulu (>30%)

Ukuguquka kakhulu okanye ukwaphuka kweentambo zobhedu, ukunciphisa amandla okuthwala umbane.

Ukuqhekeka kodonga lwesiphelo kunye nokuguqulwa kwendlela okukhokelela ekulahlekelweni kwamandla oomatshini.

Uxinzelelo lwengingqi lubangela ukuqhekeka phantsi kokwanda nokuncipha kobushushu bexesha elide.
