Iko kudikanwa kwemunyu wekupfapfaidza bvunzo ye wiring harness connectors.Zvingave zvezvishandiso zvewaya, zvakaita semakonitani, materminals, clips, kana mawiring harness assemblies, bvunzo yeDV haigone kudarika bvunzo yekupfapfaidza munyu.Kana motokari kana rori ichifamba, nzvimbo yezvibatanidza zvewaya zvinogona kusangana nemvura inopfachukira pamatairi, kunyanya mushure mechando muchando chekuchamhembe, uko munyu unoshandiswa kukurumidza kunyunguduka kwechando mumugwagwa.Aya ma-connectors anowanzoda munyu wekupfapfaidza bvunzo kuti aone kuramba kwavo ngura.
Muyero we wiring harness munyu wekupfapfaidza bvunzo bvunzo ndeyekutarisa kuvimbika kwekupokana kwekubata, kwete kutarisa kutaridzika.Izvi zvinobatanidza zvinowanzo shandiswa nezvisimbiso kuvandudza munyu pfapfaidzo kuramba.
Wire harness connector munyu pfapfaidzo bvunzo zvinoenderana nechiyero.

Ndezvipi zvinobatanidza zvinoda kuongororwa munyu?Nzvimbo dzekupfapfaidza munyu dzinonyanya kushandiswa mumauto, mota dzakakosha uye zvikumbiro zvemugungwa.Kazhinji, muyedzo wekupfapfaidza munyu unoitwa mukamuri yekupfapfaidza munyu ine 5% munyu mhinduro, uye nguva yekuratidzira ndeye 48-96 maawa.
Kupfapfaidza munyu kunoparadza zvakanyanya kune zvinhu zvakawanda uye kwakaratidza kukonzeresa kutadza kweakawanda macontact plating masisitimu, anosanganisira akakosha uye asina-akakosha masimbi ekuputira.Kana yakaedzwa nemunyu wekupfapfaidza, zvibatanidza izvo zvaive zvakakodzera nharaunda yekushandisa zvinokundikana panguva yekuedzwa.Chinangwa chebvunzo yekupfapfaidza munyu ndechekuongorora kushanda kwechigadzirwa, kwete kuchikuvadza.Munyu wekupfapfaidza bvunzo yezvibatanidza zvakafanira nharaunda dzemugungwa.Hunhu hweyedzo yekupfapfaidza munyu hunowanzo tarisa chitarisiko, kuongorora huremu uye kuyerwa kwekuramba.
Ndezvipi zvigadzirwa zvisingade kuita munyu spray test?
Kunzvimbo dzakachengetedzwa dzemotokari (semuenzaniso makabhini), kuyedzwa kwemunyu wekupfapfaidza munzvimbo dzakadai hazvidiwi.Mumashandisirwo aya, pakushandiswa kwesimbi yakakosha, nzira dzinowanzokundikana ndeye porosity corrosion uye corrosion creep, iyo inoongororwa neMFG (mixed gas flow of HCl, SO2, H2S, etc.) kuyedza.Kune iyo yekubatanidza interface yeasina kukosha esimbi machira, iyo huru yekutadza dhizaini ndeye fretting corrosion, iyo inoongororwa nekudengenyeka uye yakakwirira frequency tembiricha uye humidity bhasikoro bvunzo.
Munyu wekupfapfaidza bvunzo yetinned zvigadzirwa zve connector terminals.
Makambani mazhinji anoshandisa munyu akapfapfaidza kuongorora zvinopinda matin-plated zvigadzirwa zve connector terminals uye kutarisa chitarisiko chavo.
Izvo zvinobatanidza zvakaedzwa zvinogona kunge zvisingaonekwe kune munyu kana nharaunda dzemugungwa zvachose kana zvashandiswa, uye zvigadzirwa izvi zvinogona kuiswa munzvimbo yakachengetedzwa uko kushandiswa kwemunyu kupfapfaidza kuyedzwa kusingaratidzi kuenderana nekushandisa chaiko.
Pane firimu reoxide pamusoro pechigadzirwa che-tin-plated pachayo, uye nzira yayo huru yekutadza kushungurudza corrosion mushure mekukodzera.Muchiitiko ichi, bvunzo yekupfapfaidza yemunyu haina chekuita nekutadza kwayo.Kunyangwe iyo oxide layer iri pamusoro ikaita dema mushure mebvunzo yekupfapfaidza munyu, mukushandiswa chaiko, iyo yekumisikidza inogona kuramba iri nyore kusundira kunze kweiyo oxide firimu uye kubata tin yakachena mukati kuti igadzire simbi yekubatanidza.
Muyedzo wekupfapfaidza munyu hauna kukwidziridza, uye maawa makumi mana nemasere emunyu wekupfapfaidza haimiriri makore mangani chigadzirwa chichagara pasi pemamwe mamiriro.
Environmental kuvimbika kuyera michina.
Kuvimbika kwezvakatipoteredza kuyedza michina inoshandiswa zvakanyanya mukupisa, hunyoro hunoramba huchichinja, kushandura tembiricha uye hunyoro, munyu wekupfapfaidza bvunzo kubva kune yakabikwa, chikamu chikamu, redunhu bhodhi/module level, kupedzisa muchina zvemagetsi, midziyo yemagetsi, simba remagetsi nezvimwe. zvigadzirwa.Yakasanganiswa gasi bvunzo, ozone kuchembera bvunzo, UV yakamhanyisa kuchembera bvunzo, xenon mwenje kuchembera bvunzo, sulfur dioxide corrosion test, high-altitude low pressure test, IPX1～8 mvura isingapinde muyedzo, guruva/jecha bvunzo, donhwe bvunzo, combustion test, hafu sine wave / Trapezoidal wave acceleration shock bvunzo, sine/random vibration bvunzo, crash simulation bvunzo, donhwe bvunzo, tensile simba bvunzo, kuneta bvunzo, kudengenyeka kwepasi, kukurumidza kukurumidza kwehupenyu kuchembera uye kushushikana kutarisisa uye kumwe kuyedza kwemakanika uye mechini kwezvakatipoteredza, mamiriro ekunze bvunzo uye yakazara Environmental test project.
