5. Cov kev xav tsis zoo txog tooj dag Screws & Polarity
Txhawm rau teb tag nrho "Puas yog tooj dag screws nruab nrab lossis kub?", peb yuav tsum tau debunk tsis tu ncua dab neeg:
5.1 Lus dab neeg: "Brass Screws Kub Vim Lawv yog tooj dag-xim"
False-xim tsis muaj feem xyuam rau polarity. Cov ntsia hlau tooj dag yog tooj dag-xim vim lawv cov tooj liab-zinc alloy, tsis yog vim lawv nqa cov xov hlau kub. Silver screws (feem ntau npib tsib xee-plated steel) feem ntau muaj kev ruaj ntseg ntawm cov xov hlau tsis zoo, tab sis qhov no yog kev lag luam kev sib cog lus, tsis yog cov khoom siv.
5.2 Myth: "Conductive Brass Screws Tsim Short Circuits"
Tsis tseeb- tooj dag ntsia hlau tsuas yog ua rau luv luv yog tias lawv kov lwm qhov chaw ua haujlwm (xws li, lub xov hlau kub ntawm lub hau ntswj kov lub xov tooj nruab nrab ntawm lub davhlau ya nyob twg). Cov khoom tsim tau zoo (xws liJOYEAR's stamping qhov chaw) muaj insulated los yog sib cais terminals los tiv thaiv qhov no.
5.3 Myth: "Brass Screws yuav tsum tsuas yog siv nrog cov hlau kub"
False- tooj dag screws ua haujlwm nrog cov xaim nruab nrab, cov xaim kub, lossis cov xaim hauv av, tsuav yog lawv txuas nrog lub davhlau ya nyob twg raug. Lawv conductivity thiab corrosion kuj ua rau lawv ntau yam rau tag nrho peb lub luag hauj lwm.
