Ongororo pakusarudzwa kwemotokari wiring harness terminal coating

[Abstract] Panguva ino, kuitira kuti tive nechokwadi chekusangana uye kubatanidzwa kwepamusoro kwemabasa emagetsi emotokari, uye kusangana nekugadzirwa kwechigadzirwa chitsva chemagetsi emagetsi, iyo inowanzosarudzwa yekubatanidza ine dhigirii yekubatanidza (kwete chete kutumira yakakwirira. ikozvino uye yakakwira simba rekupa, asiwo kuendesa yakaderera-voltage uye yakaderera-ikozvino analog masaini), sarudza akasiyana mazinga ekubatanidza zvimiro zveakasiyana mabasa uye akasiyana zvigaro kuti ave nechokwadi chekuti hupenyu hwesevhisi hwekubatanidza haufanirwe kunge hwakaderera pane hupenyu hwesevhisi. yemotokari dzakajairwa, mukati meiyo inotenderwa kukanganisa dhairekitori Kutepfenyura kwakagadzika kwemagetsi uye masaini ekudzora kunofanirwa kuve nechokwadi;ma-connectors akabatanidzwa kuburikidza nematerminals, uye materminal echirume neakadzi anogadzirwa nesimbi conductive zvinhu.Unhu hwekubatanidza kwekupedzisira hunokanganisa zvakananga kuvimbika kwemabasa emagetsi emotokari.

1. Nhanganyaya

Iwo mawaya materminal ekufambiswa kwazvino mumotokari wiring harness majoini anowanzo kudhindwa kubva kumhando yepamusoro yemhangura alloys.Chimwe chikamu chematerminals chinofanirwa kusungirirwa kugomba repurasitiki, uye chimwe chikamu chinofanira kunge chakabatana nemagetsi kune mating terminals.The alloy yemhangura Kunyange zvazvo iine yakanaka mechanical properties, kushanda kwayo mumagetsi conductivity haigutsi;Kazhinji, zvinhu zvine maitiro akanaka emagetsi ane mavhareji emagetsi emagetsi, akadai setin, ndarama, sirivha, nezvimwe zvakadaro.Naizvozvo, plating inonyanya kudiwa kuti ipe materminals anogamuchirwa emagetsi conductivity uye michina zvinhu panguva imwe chete.

2 Mhando dzePlating

Nekuda kwemabasa akasiyana ematerminals uye akasiyana ekushandisa nharaunda (yakakwira tembiricha, kutenderera kwemafuta, humidity, kudedera, vibration, guruva, nezvimwewo), iyo yakasarudzwa terminal plating zvakare yakasiyana, kazhinji kuburikidza neyakakura inoenderera tembiricha, plating ukobvu, mutengo, kubatanidza Iyo yakakodzera plating layer yeiyo mating terminal ndeyekusarudza materminal ane akasiyana plating layer kuti asangane nekugadzikana kwebasa remagetsi.

3 Kuenzanisa kweCoatings

3.1 Tin-plated zviteshi
Tin plating kazhinji ine kugadzikana kwakanaka kwezvakatipoteredza uye mutengo wakaderera, saka inoshandiswa zvakanyanya, uye kune akawanda marata ekurovesa anoshandiswa muzvinhu zvakasiyana, senge rima rakasviba, rinopenya, uye inopisa dip tin.Kuenzaniswa nemamwe machira, kusamira kwekupfeka kwakashata, kusingasviki gumi kutenderera kutenderera, uye kuita kwekubata kunoderera nekufamba kwenguva uye tembiricha, uye inowanzoshandiswa mumamiriro ekunze ari pasi pe125 ° C.Paunenge uchigadzira tin-plated terminals, yakakwirira yekubata simba uye kudiki kusimuka kunofanirwa kutariswa kuve nechokwadi kugadzikana kwekusangana.

3.2 Silver Plated Terminals
Silver plating kazhinji ine yakanaka point contact performance, inogona kushandiswa nguva dzose pa150 ° C, mutengo wacho unodhura, zviri nyore kuita ngura mumhepo pamberi pesarufa nechlorine, yakaoma kupfuura tin plating, uye resistivity yayo zvishoma. yakakwirira kupfuura kana yakaenzana netin, iyo inogona kuitika electromigration phenomenon inotungamira zviri nyore kune dzingangove njodzi mukubatanidza.

3.3 Goridhe-yakaiswa zviteshi
Goridhe-yakaputirwa materminal ane yakanaka kuonana kuita uye kugadzikana kwezvakatipoteredza, iyo inoenderera tembiricha inogona kudarika 125 ℃, uye ine yakanakisa friction kuramba.Goridhe rakaomarara kudarika tin nesirivheri, uye rine kupesana nekukweshana kwakanaka, asi mutengo waro wakakwirisa, uye kwete yese terminal inoda goridhe plating.Kana simba rekubatanidza radzikira uye tin plating layer yapfekwa, goridhe rinoiswa panzvimbo.Terminal.

4 Kukosha kweiyo Terminal Plating application

Iyo haigone chete kuderedza kukora kweiyo terminal zvinhu zvepasi, asi zvakare kugadzirisa iyo yekuisa simba mamiriro.

4.1 Deredza kupokana uye kuderedza kuisa simba
Zvinhu zvikuru zvinokanganisa coefficient of friction pakati pematerminals zvinosanganisira: zvinhu, kushata kwepamusoro, uye kurapwa kwepamusoro.Kana iyo terminal inogadziriswa, iyo friction coefficient pakati pematerminal inogadziriswa, uye roughness yakaenzana yakakura.Kana iyo pamusoro peiyo terminal ichibatwa nejasi, iyo yekupfekedza zvinhu, ukobvu hwekufukidzira, uye kupera kwekuputira zvine mhedzisiro yakanaka pane friction coefficient.

4.2 Dzivirira oxidation uye ngura mushure mekunge terminal plating yakuvadzwa
Mukati menguva gumi dzinoshanda dzekupura uye kuburitsa, materminal anodyidzana nemumwe kuburikidza nekukanganisa kukwana.Kana paine kudzvinyirirwa kwekubatana, kutama kwehama pakati pechirume nechikadzi kunokuvadza plating pane iyo terminal kana kuikwenya zvishoma panguva yekufamba.Tsananguro dzinotungamira mukukora kusina kuenzana kana kufumurwa kwejasi, zvichikonzera shanduko yemuchina, kukwenya, kunamatira, kupfeka marara, kutamisa zvinhu, nezvimwewo, pamwe nekugadzirwa kwekupisa. Nguva zhinji dzekupura uye kuburitsa, kunowedzera kujeka mavanga ari pamusoro peiyo terminal.Pasi pechiito chebasa renguva refu uye mamiriro ekunze, iyo terminal iri nyore kwazvo kukundikana.Izvo zvinonyanya kukonzerwa neiyo oxidative corrosion inokonzerwa nediki diki kufamba kwenzvimbo yekusangana, kazhinji 10 ~ 100μm hama yekufamba;kufamba kwechisimba kunogona kukonzeresa kupfeka kunokuvadza pakati penzvimbo dzekusangana, kuzunguzika kushoma kunogona kukonzera friction corrosion, kuvhunduka kwemafuta uye kupesvedzera kwezvakatipoteredza kunomhanyisa maitiro.

5 Mhedziso

Kuwedzera plating layer kune iyo terminal haingogone kuderedza ngura pamusoro peiyo terminal zvinhu, asi zvakare kunatsiridza mamiriro ekuisa simba.Zvisinei, kuitira kuti uwedzere basa uye hupfumi, iyo plating layer inonyanya kureva mamiriro anotevera ekushandiswa: inogona kumira mamiriro chaiwo ekushisa kweiyo terminal;kuchengetedza kwezvakatipoteredza, kusaora;kugadzikana kwemakemikari;yakavimbiswa terminal kuonana;kuderedza kukakavara uye kupfeka insulation;mutengo wakaderera.Sezvo nzvimbo yemagetsi yemotokari yose inowedzera uye yakaoma uye nguva itsva yesimba iri kuuya, chete nekugara uchiongorora teknolojia yekugadzira yezvikamu uye zvikamu zvinogona kukurumidza kudzokorora kwemabasa matsva.
