USB-IF Association yav dhau los tau tshaj tawm ntawm Type-C tus qauv kev hloov pauv kev hloov pauv hloov pauv (Hom-C Spec ECN), lubUSB Hom-C Cable thiab ConnectorSpecification R2.2 specification los hloov kho cov ntsiab lus ntawm lub neej yav tom ntej ntawm USB cable, connector thiab ntaus ntawv forensics hais txog cov ntsiab lus, nrog rau kev hloov kho rau lub cable Qhov hloov tshiab rau USB hom-C Cable thiab Connector Specification R2.2 npog rau yav tom ntej ntawm USB cables, connectors thiab ntaus ntawv pov thawj, nrog rau kho qhov ntau thiab tsawg cable thiab qhib USB 3.1 Gen1 hom-C legacy cable ntawv pov thawj.
Dab tsi yog qhov kev hloov pauv uas tsim nyog tau txais kev mloog ntawm kev lag luam txuas?
Tshwj xeeb, USB-IF tseem tab tom siv version 2.1b ntawm cable connector daim ntawv pov thawj xeem specification (Universal Serial Bus Type-C Connectors thiab Cable Assemblies Ua Raws Li Cov Ntaub Ntawv Kho 2.1b/2021). Cov kev hloov tshiab hauv qab no yuav tsum tau muab coj los siv thaum qhov txuas ntxiv ntawm qhov kev xeem ntawv pov thawj tau muab tso tawm.
Cable Standards
Ua ntej, USB Hom-C cable ntsaws qhov ntev tau hloov kho kom kho cov kab hluav taws xob sab nraud molding dav. Qhov dav ntawm cov pwm sab nrauv ntawm lub cable tau hloov kho los ntawm qhov siab tshaj plaws ntawm 12.35mm mus rau qhov siab tshaj plaws ntawm 12.85mm; Tsis tas li ntawd, qhov tuab ntawm cov pwm sab nraud ntawm lub cable tau raug kho, thiab qhov dav ntawm cov pwm sab nraud ntawm lub cable tau hloov kho los ntawm qhov siab tshaj plaws ntawm 6.5mm mus rau qhov siab tshaj plaws ntawm 7.0mm; Nyob rau tib lub sijhawm, qhov sib txawv ntawm qhov yuav tsum tau ua rau ntau yam USB Hom-C txuas kuj tau hloov kho, thiab qhov kev ncua deb ntawm cov khoom sib txuas tau hloov kho los ntawm qhov tsawg kawg nkaus ntawm 12.85mm mus rau qhov tsawg kawg nkaus ntawm 13.35 hli.Vertical nrug ntawm qhov sib txuas ntawm qhov sib txuas los ntawm qhov tsawg kawg nkaus ntawm 7mm hloov kho kom tsawg kawg ntawm 7.50mm.
Qhov thib ob, cov ntsiab lus tseem hloov kho cov qauv ntawv pov thawj cable, qhib USB 3.1 Gen1 Type-C legacy cable certification. Cov lus qhia yav dhau los tau teev tseg tias USB 3.1 Hom-C legacy cable tsuas yog tso cai Gen2 hom kab ntawv pov thawj, qhov kev hloov tshiab no yuav tso cai rau Gen1 hom kab ntawv pov thawj, qhov qhib tshiab ntawm ob hom cable rau USB 3.1 Gen1 Standard-A rau Hom-C Cable thiab USB 3.1 Gen1 Hom-C rau Micro-B cable, USB 3.1 Gen1 Hom-C rau Micro-B cable. Cov cables txhawb 5Gbps kis tau tus mob thiab tuaj yeem ntev txog 2m.
