JM36111-KD20-4F Single Port 8P8C Modular JackRJ45T/H Cholumikizira

Chifukwa chiyani cholumikizira cha RJ chikuwoneka cholumikizira chabodza chogulitsa RJ?Tidatsegula cholumikizira cha RJ, ndipo tidawona kuti zida za solder zinali zabodza, kapena waya wamkuwa adasweka.Chifukwa chiyani izi?Imayesedwa kwathunthu pamapeto opangira RJ.Koma ndichifukwa chiyani amatsitsidwa ku pulogalamu ya kasitomala asanadziwike?
Zida zoyesera zomwe zimagwiritsidwa ntchito kwambiri ndi LCR Meter, yomwe ndi inductance capacitance resistance tester.Kuperewera kwa zida zoyeserera zamtunduwu ndikuti sikungathe kuyeza kukana kwa DC, kutsekeka kwa AC kokha, komanso kulumikizana kwa mzere woyeserera ndiutali, ndipo kulumikizidwa kumafunika, komwe kumawonjezera mosawoneka mtengo wamtundu wa AC wa mzere wonse woyeserera, kotero AC impedance Malire oyesera sangakhazikitsidwe ang'onoang'ono, nthawi zambiri amakhala 5ohms, apo ayi zolumikizira zambiri za RJ zolumikizira mizere yabwino zidzalembedwanso kuti ndizolakwika ndipo sizingapangidwe.
Pazida zoyeserera zamtunduwu, titha kuyesa kukana kwa DC, ndipo malire a mayeso amatha kukhala 1.5ohms kapena ngakhale pansi pa 1ohm.Mwanjira imeneyi, cholumikizira chilichonse cha RJ chokhala ndi mizere yocheperako pang'ono chikhoza kulembedwa ngati chinthu cholakwika Chepetsani chiopsezo cha kutayikira kumbali ya ntchito.
