Abstract-A press-fit connector for automobile airbag electronic
control units (ECUs) idapangidwa ndikusamutsidwa ku misagawo lopanga ndi Sumitomo Wiring Systems, LtdAutoNetworks Technologies, Ltd. mu 2005.
Kulumikizidwe kokwanira kwa makina osindikizira ndi kulumikiza kwamagetsi kosagulitsateknoloji, yomwe imagwiritsa ntchito mphamvu yolumikizana ndi makina opangidwapakati pa mabowo pa bolodi losindikizidwa (PCB) ndimatheminali okhala ndi m'lifupi okulirapo pang'ono kuposa bowo lodutsaawiri.
Tekinoloje iyi yadziwika kwambiri posachedwa ngati muyesomotsutsana ndi "Zofunikira Zaulere Zotsogola" zazinthu zomwe zilizida zamagetsi / zamagetsi.
Pogwiritsa ntchito ukadaulo uwu pa zolumikizira zamagalimoto,tiyenera kuganizira zovuta kwambiri zachilengedwezofunikira.
Chifukwa chake, cholumikizira chofikira pama airbag ECUsyapangidwa bwino ndikupangidwa mochuluka kuyambira 2005.
Komanso, olemba apanganso mtundu watsopano wa zovutakuyika malata pamaterminals, motero kuletsa kuti malata asachotsedwepanthawi yolowetsamo, zomwe zingayambitse kufupikitsaku PCB.

A. Kutsogola Kwaulere Chofunikira ndi Kulumikizana ndi Press-fit
Pali chizoloŵezi chapadziko lonse chofuna kuchotsa zinthu zoopsa
zipangizo zochokera kumagetsi/zida zamagetsi (monga RoHSMalangizo [1]).Makamaka, chitukuko cha lead free solderndichofunika kwambiri m'mafakitale amagetsi/magetsipadziko lonse lapansi.
Komano, m'dera la magalimoto zamagetsicontrol units (ECUs), pali chidwi ndi solderless press-fitukadaulo wolumikizira pakuyika mtundu wolowetsa ngakhale-bowozigawo, monga zolumikizira, zomwe zidakwaniritsidwa kale ndi anjira yozungulira kapena yowongolerera.
Ngakhale teknoloji iyi yakhala ikuvomerezedwa mwachizolowezim'dera la zida zoyankhulirana pazaka zingapo zapitazi
kwa zaka zambiri, pakhala pali ziyembekezo zazikulu pakugwiritsa ntchito kwawo kolumikizira magalimoto, posachedwa kutengera miyeso yomwe imayang'anira zofunikira zaulere.
Kulumikizana ndi makina osindikizira ndi njira yaukadaulo yolumikizira magetsi, yomwe imagwiritsa ntchito mphamvu yolumikizirana yamakina yomwe imapangidwa pakati pa mabowo pa bolodi losindikizidwa (PCB) ndi ma terminals okulirapo pang'ono kuposa kukula kwa dzenje, monga tawonera mkuyu. . 1.
Ukadaulowu ulinso ndi maubwino owonjezera a (I) Palibe njira yowonjezera yotenthetsera pazida zokwera pamwamba, (2) Palibe chifukwa chogwiritsa ntchito mapulasitiki osamva kutentha panyumba yolumikizira, chifukwa njira yoyikira ma terminal (ie Press-fit Connection) imachitika pa kutentha kwa chipinda komwe kufotokozedwa mu Table I.
Kugwiritsa ntchito kovomerezeka kumangokhala: Cornell University Library.Adatsitsidwa pa Novembara 11,2022 nthawi ya 05:14:29 UTC kuchokera ku IEEE Xplore.Zoletsa zikugwira ntchito.
