Iindaba

Ngoku,izithuthi zamandla amatshaziphuhlisa kwicala lamandla ombane aphezulu kunye nomgangatho ophezulu wangoku.Ezinye ii-high-voltage systems ziyakwazi ukumelana nomthamo wombane ukuya kutsho kuma-800V kunye nemisinga ukuya kuma-660A.Imisinga emikhulu ngolo hlobo kunye nombane uya kuvelisa imitha ye-electromagnetic, eya kuphazamisana nokusebenza okuqhelekileyo kwamanye amacandelo e-elektroniki.

Kukho iindlela ezixhaphakileyo zokukhusela uphazamiseko lwe-electromagnetic kwi-high-voltage intambo yokubopha:

(1) I-conductor inomaleko wayo okhuselayo

Beephantsi ngumzobo weskim sesakhiwo socingo olulodwa olungundoqo olunombane olukhuselayo, oludla ngokuqulunqwa ngamaleko amabini ezinto eziqhubela phambili zesinyithi kunye nemigangatho emibini yezinto zokugquma, ukusuka ngaphakathi ukuya ngaphandle ngundoqo. , i-insulation layer, i-shielding layer, i-insulation layer.I-core core yenziwe ngobhedu okanye i-aluminium, engumthwali wangoku.Xa umsinga udlula kumbindi wocingo, ukuphazamiseka kwe-electromagnetic kuya kuveliswa, kwaye indima yomaleko okhuselayo kukukhusela ukuphazamiseka kwe-electromagnetic, ukuze ukuphazamiseka kwe-electromagnetic kuqale kumbindi wocingo kwaye kume kumaleko okukhusela, kwaye akuyi kukhutshwa. ukuphazamisana nezinye izixhobo zombane.

Ulwakhiwo oluqhelekileyo lokhuselo lunokwahlulwa lube ngamatyala amathathu,

① Isikhuselo esilukiweyo ngefoyile yentsimbi

Ngokuqhelekileyo iqulunqwe ngamacandelo amabini: i-metal foil kunye ne-braided shielding layer.I-foil yensimbi idla ngokuba yi-aluminium foil, kwaye i-braided shielding layer ivame ukuphonswa ngocingo olunobhedu olulukiweyo, kwaye izinga lokugquma ngu-≥85%.I-foil yensimbi isetyenziselwa ikakhulu ukukhusela ukuphazamiseka kwe-high-frequency, kunye nekhaka eliphothiweyo kukuthintela ukuphazamiseka okuphantsi.Ukusebenza kokukhusela intambo ephezulu ye-voltage iquka iinxalenye ezimbini, i-impedance yokudlulisa kunye nokukhusela ukukhusela, kunye nokusebenza kakuhle kokukhusela intambo yocingo ngokuqhelekileyo kufuna ukufikelela ≥60dB.

I-conductor ene-shielding layer ifuna kuphela ukukhupha i-insulation layer xa ihlutha ucingo, kwaye emva koko i-crimp i-terminal, ekulula ukuyiqonda imveliso ezenzekelayo.Ucingo olunomqolo okhuselayo lusebenzisa uyilo lwesakhiwo se-coaxial, ukuba ufuna ukufezekisa unyango lwe-peeling yemigangatho emibini yokugquma kwisixhobo, ucingo ngokwalo luyafuneka ukuba lube neqondo eliphezulu le-coaxial, kodwa oku kunzima ukufezekisa kwinkqubo yokuvelisa yokwenene yocingo, ngoko ukuze ungonakalisi i-core wire xa ukhulula ucingo, kuyimfuneko ukuphatha iileya ezimbini zokugquma ngokwahlukileyo.Ukongeza, umaleko okhuselayo nawo ufuna unyango olukhethekileyo.Ngocingo olunoluhlu lwalo olukhuselayo, inkqubo ye-wiring harness processing kunye nenkqubo yokuvelisa ibandakanya amanyathelo angaphezulu afana nokuxobula, ukusika i-aluminium foil, ukusika umnatha okhuselayo, i-mesh yokugubungela, kunye ne-crimping shielding ring, njengoko kubonisiwe kuMfanekiso 3. Inyathelo ngalinye lifuna izixhobo ezandisiweyo. kunye nokufakwa ngesandla.Ukongeza, ukuba kukho ukushiyeka xa kusingathwa i-shield layer, okukhokelela ekudibaneni phakathi kwe-shield layer kunye ne-core, kuya kubangela iingxaki ezinzulu zomgangatho.

② Ikhaka elinye eliphothiweyo

Esi sakhiwo sekhebula esiphezulu siyafana nekhaka eliphothiweyo kunye nesakhiwo se-foil yensimbi ekhankanywe ngasentla, kodwa i-shield layer isebenzisa kuphela ikhaka ephothiweyo kwaye akukho foil yensimbi, njengoko kuboniswe kulo mfanekiso ulandelayo.Ekubeni i-foil yesinyithi isetyenziselwa ukuthintela ukuphazamiseka kwe-high-frequency, impembelelo yokukhusela kwesi sakhiwo sokuphazamiseka kwe-electromagnetic high-frequency imbi kakhulu kunokukhusela okuphothiweyo kunye ne-foil yesinyithi, kwaye uluhlu lwesicelo alubanzi njengokhuselo olulukiweyo kunye ne-foil yesinyithi. ukukhusela, kunye nenkqubo yokuvelisa i-wiring harness, ngamanyathelo amancinci kuphela okusika i-aluminium foil, kwaye yonke inkqubo yemveliso ayilungiswanga kakuhle.

Ukuze kuphuculwe iingxaki zokusetyenzwa okubangelwa yindlela yokukhusela yemveli, abanye abaphengululi bafunda isikhuselo sentambo enevoltage ephezulu eyenziwe ngefoyile yobhedu enobubanzi obuyi-13 ~ 17mm kunye nobukhulu be-0.1 ~ 0.15mm kwindawonI-engile ye-30 ~ 50, kunye ne-1.5 ~ 2.5mm ejikelezayo phakathi komnye nomnye.Eli khaka lisebenzisa kuphela ifoyile yesinyithi, ukuphelisa amanyathelo okusika umnatha, ukuguqula umnatha, ukucinezela umsesane wekhaka, njl. njl., eyenza lula kakhulu inkqubo yokuvelisa i-wire harness, inciphisa iindleko zocingo, kwaye igcine utyalo-mali lwezixhobo zokunqanda ikhaka. umsesane.

③ Ikhaka lefoyile yentsimbi enye

Ezi ndlela zininzi zingentla kuyilo lokhuselo locingo oluphezulu lombane.Ukuba uqwalasela ngokwembono yokunciphisa iindleko kunye nokuphucula uyilo lwesinxibelelanisi kunye nenkqubo yokuvelisa intambo yokubopha, ungasusa ngokuthe ngqo umaleko okhuselayo wocingo ngokwawo, kodwa kuyo yonke inkqubo ye-high-voltage, i-EMC kufuneka iqwalasele, ngoko ke kuyimfuneko ukuba yongeza amacandelo anemisebenzi yokukhusela kwezinye iindawo.Okwangoku, isisombululo esiqhelekileyo kwiintambo zombane ophezulu kukongeza umkhono okhuselayo ngaphandle kocingo okanye ukongeza isihluzo kwisixhobo.

(2)Yongeza umkhono okhuselayo ngaphandle kocingo;

Le ndlela yokukhusela ibonwa ngomkhono wocingo ongaphandle okhuselayo.Isakhiwo socingo oluphezulu lwe-voltage ngeli xesha luluhlu lwe-insulation kuphela kunye nomqhubi.Olu lwakhiwo lwengcingo luya kunciphisa iindleko zababoneleli ngocingo;Kubavelisi beentambo zocingo, inokwenza lula inkqubo yokuvelisa kunye nokunciphisa igalelo lezixhobo;Ukuyila i-high-voltage connectors, isakhiwo se-high-voltage connector siye saba lula ngenxa yesidingo sokuqwalasela ukuyila amakhonkco okukhusela.

I-2024 Beijing Automotive Wiring Harness and Connector Exhibition iya kuphinda ibambe i-Automotive wiring harness kunye neForam yeNgqungquthela yeNgqungquthela ngaxeshanye, imema imibutho yoshishino kunye nabaphathi beenkampani ukuba babelane ngezihloko ezishushu ezifana nokufakwa kwesicelo sokumisa i-automotive wiring harness kuphuhliso lwabakrelekrele. ushishino lweemoto oludityanisiweyo kunye neendlela zophuhliso lwexesha elizayo.Ngokuthatha inxaxheba, abantu banokuqonda ngokukhawuleza ubume bophuhliso kunye neendlela zokusika zeshishini.

Izithuthi zamandla amatsha zibeka phambili iimfuneko ezahlukeneyo neziphezulu nangaphezulu kwiintambo zokubopha iintambo kunye nezihlanganisi.Njengenxalenye ebalulekileyo yeendawo zemoto, iintambo zokubopha iintambo kunye nezihlanganisi kufuneka zisebenzise ngakumbi itekhnoloji yokulawula ucingo ukufezekisa inqanaba eliphezulu lolawulo lokuqhuba ngobukrelekrele.I-harness yokulawula ephethe imiqondiso yedijithali ithatha indawo ye-hydraulic okanye i-wire control components yesiqhelo ukuphumeza ulawulo olukhawulezayo noluchaneke ngakumbi lwesithuthi olufana ne-braking kunye ne-steering.Njengoko inkqubo iya isiba nzima ngakumbi, i-harness yesithuthi isengozini ngakumbi kungquzulwano, ukungqubana, izinyibilikisi ezahlukeneyo kunye nolunye ukhukuliseko lokusingqongileyo lwangaphandle kunye nokusilela kwesekethe kunye nezinye iintsilelo, ngoko ukhuseleko kunye nokuqina kwe-harness nayo yenye yeepropati ezibalulekileyo ukuba kufuneka ukuhlangabezana.
