Dab tsi yog hom D-sub connectors?
D-Sub, raws li ib qho ntawm cov tshuab sib txuas sib txuas, muaj ntau hom kev sib txuas nyob ntawm txoj kev teeb tsa.
Kev tsis zoo sab nraum zoov lossis sab hauv tsev tuaj yeem ua rau cov khoom siv hluav taws xob puas. Standard D-sub connectors tsis tiv taus cov kab mob xws li dej thiab hmoov av. Cov hlau txuas no muaj nyob rau hauv cov txiv neej lossis poj niam qauv hauv DB9, DB15, DB25, thiab HD15 qhov ntau thiab tsawg. Lawv tuaj yeem phim cov kab hluav taws xob ntawm 30-20AWG. Nws cov qauv nta kub-plated tooj liab hu, nickel plated steel vaj tse, thiab ib lub nplhaib silicone rwb thaiv tsev. Qhov siab tshaj plaws ntawm lub vaj huam sib luag yog 0.078 nti.
Piv rau crimped connectors, ntau DIY cov neeg siv nyiam xaiv soldered D-sub connectors. Cov DB15 connectors no ua raws li cov qauv kev lag luam kev lag luam thiab tuaj yeem ua ke nrog txhua qhov sib xws DB15 connector. Hu rau electroplating flash kub, connector rwb thaiv tsev raws li UL94V-0 tus qauv. Qhov siab tshaj plaws hlau loj yog 20 AWG.
Nyob rau ntawm qhov chaw txiav cov poj niam connectors muab ib txoj hauv kev yooj yim thiab yooj yim rau ntawm - qhov chaw txiav cov cables. Tag nrho 9 tus pins ntawm lub connector, nrog rau hauv av, yog nruab nrog cov ntsiab lus sib txuas. Lub thawv sib txuas tsim nrog cov ntsia hlau txuas muab kev sib txuas hluav taws xob txhim khu kev qha yam tsis tas yuav muaj cov cuab yeej tshwj xeeb. Kom meej meej kos lub junction box cheeb tsam kom paub tseeb tias foolproof thiab raug txiav.
Siv rau kev txiav cov ntaub ntawv ntau tus neeg xyuas pib thiab cov yeeb yaj kiab cables, cov kev xaiv vuam thiab crimping muaj, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev loj - nplai cable ntau lawm.
Txoj cai kaum D-Sub PCB connectors feem ntau yog siv nyob rau hauv ntau yam I/O daim ntawv thov. Lub rooj tsavxwm xauv muab kev ruaj ntseg PCB txuas thiab yooj yim rau solder txhua lub sijhawm. Lub connector muaj DB9, DB15, DB25, DB37, thiab HD15 specifications.
