Abubuwan cika ruwa na toshe ruwa yawanciyarn mai toshe ruwa(igiya) da foda mai hana ruwa. Ana amfani da foda mai toshe ruwa mafi yawa don toshe ruwa tsakanin murɗaɗɗen muryoyin madugu. Lokacin da foda mai toshe ruwa yana da wuyar haɗawa zuwa monofilament na madubi, ana iya amfani da mannen ruwa mai kyau a waje da mai sarrafa ruwa, kuma ana iya nannade foda mai hana ruwa a waje da mai gudanarwa. Ana amfani da yarn mai toshe ruwa (giya) sau da yawa don cike giɓi tsakanin igiyoyi masu matsakaicin matsa lamba uku.
3 Gabaɗaya tsarin juriya na ruwa na USB
Dangane da yanayi daban-daban na amfani da buƙatun, tsarin juriya na ruwa na kebul ya haɗa da tsarin hana ruwa na radial, tsayin daka (ciki har da radial) tsarin juriya na ruwa da tsarin juriya na kowane zagaye. Ana ɗaukar tsarin toshe ruwa na kebul na matsakaicin matsakaicin matsakaicin cibiya uku a matsayin misali.
3.1 Radial hana ruwa tsarin uku-core matsakaici irin ƙarfin lantarki na USB
Radial waterproofing na uku-core matsakaici irin ƙarfin lantarki na USB gabaɗaya rungumi dabi'ar Semi-conductive ruwa tarewa tef da roba mai gefe biyu tef aluminum don cimma ruwa juriya aiki. Babban tsarinsa shine: madugu, madugu garkuwa Layer, rufi, rufi garkuwa Layer, karfe garkuwa Layer (Copper tef ko jan karfe waya), talakawa ciko, Semi-conductive ruwa tarewa tef, biyu-gefe roba mai rufi aluminum tef a tsaye kunshin, m kwasfa. .
3.2 Uku-core matsakaici irin ƙarfin lantarki na USB a tsaye tsarin juriya
Kebul na matsakaicin matsakaici mai mahimmanci uku kuma yana amfani da tef ɗin toshe ruwa mai ɗaukar nauyi da tef ɗin alumini mai rufi mai gefe biyu don cimma aikin juriya na ruwa. Bugu da ƙari, ana amfani da igiya mai toshe ruwa don cike gibin da ke tsakanin manyan igiyoyi guda uku. Tsarinsa na gabaɗaya shine: madugu, madubi garkuwa Layer, rufi, rufi garkuwa Layer, Semi-conductive ruwa tarewa tef, karfe garkuwa Layer (na jan karfe tef ko jan karfe waya), ruwa tarewa igiya cika, Semi-conductive ruwa tarewa tef, waje kwasfa.
3.3 Uku-core matsakaici irin ƙarfin lantarki na USB duk-zagaye ruwa juriya tsarin
Tsarin toshe ruwa na kebul na kowane zagaye yana buƙatar cewa mai gudanarwa shima yana da tasirin toshe ruwa, kuma tare da buƙatun hana ruwa na radial da toshe ruwa mai tsayi, don cimma nasarar toshe ruwa. Tsarinsa na gabaɗaya shi ne: madugu mai hana ruwa, madubin garkuwar kariya, rufin, rufin garkuwa, tef ɗin hana ruwa mai ɗaukar nauyi, Layer garkuwar ƙarfe (tef ɗin jan ƙarfe ko waya ta jan ƙarfe), cika igiya mai hana ruwa, tef ɗin toshe ruwa mai ƙarfi. , Fakitin madaidaiciyar tef mai gefe biyu filastik mai rufi, kwasfa na waje.
Za a iya inganta kebul na toshe ruwa mai guda uku zuwa sifofin kebul na toshe ruwa guda uku (mai kama da tsarin kebul ɗin da aka keɓe na iska mai guda uku). Wato ana fara samar da kowace cibiyar sadarwa ta USB ne bisa tsarin kebul mai hana ruwa guda daya, sannan a karkatar da igiyoyi daban-daban guda uku ta hanyar kebul domin maye gurbin na USB mai hana ruwa guda uku. Ta wannan hanyar, ba wai kawai inganta juriya na ruwa na kebul ba, amma kuma samar da dacewa don sarrafa na USB da kuma shigarwa daga baya da kuma shimfiɗawa.
