Ferrule

No laila he aha ka ferrule? Ma ka ʻōlelo maʻamau, ʻo kēlā me kēia ʻano o ke kaula a i ʻole ka clip i hoʻohana ʻia e hoʻohui, hoʻoikaika a paʻa paha i nā mea. hoʻohana ʻia e hoʻopili i nā kaula uea.
ʻO ka ferrule uea he paipu metala palupalu i ʻoki ʻia a hiki i ka hopena o kahi uea i hoʻopaʻa ʻia e hoʻomaikaʻi i nā ʻano pili o ka uea. a me ka lōʻihi. Akā naʻe, ʻoi aku ka nui o ka ferrule ma mua o ka cylinder maʻalahi - he lehelehe a i ʻole ka lapalapa ma kekahi ʻaoʻao e hōʻiliʻili a hoʻohui i ke kaula hoʻokahi o ke kaula i ka wā e hoʻokomo ʻia ai ka ferrule.
ʻAʻole ʻike koke ʻia ka lapalapa i loko o ka hapa nui o nā ferrules no ka mea, ua wahī ʻia ia i loko o kahi lima hoʻokomo ʻia i loko o ka lima. ferrule. ʻAʻole like me nā pili crimp maʻamau, ʻaʻole i hoʻopaʻa ʻia ka lima plastik o ka ferrule i ka wā o ka hoʻokomo ʻana. ʻO ka hapa nui o nā lima lima ferrule i hoʻopaʻa ʻia no ka nui uea i ka maʻamau DIN 46228, ʻo ia hoʻi, me ka huikau, ʻelua mau code ʻokoʻa, Farani a me Kelemania, i nā millimeters square no ka ʻāpana cross-sectional like.
Inā ʻoi aku ka leo o ka ferrule i kahi mea ʻEulopa ma mua o kahi mea ʻAmelika, ʻo ia ke kumu maikaʻi. No ka loaʻa ʻana o ka hōʻoia CE, pono nā mea uila e hoʻopau i nā uea stranded i ka screw a i ʻole ka puna puna me nā ferrules. ʻAʻole maʻamau ka hoʻohana ʻana i nā ferrules i nā polokalamu US. Akā, he mau pono kikoʻī ko nā ferrules i paʻakikī ke hōʻole ʻia, a ʻike ʻia ka laha ʻana o kā lākou hoʻohana ʻana no ka mea ʻoi aku ka maikaʻi o ka ʻenekinia.
No ka hoʻomaopopo ʻana pehea, e hoʻopaʻa i kahi ʻāpana pōkole o ka uea i hoʻopaʻa ʻia i hoʻopaʻa ʻia. , ma kekahi hapa no ka mea e uhi ana ka insulation i na kaula o ka conductor, e hoomau ana ia lakou i ka pili pili ana a me ka malama ana i na kaula o kela mea keia mea i wili a waiho i waho. Hoʻopilikia ʻia nā kaula - wehe iki lākou.
ʻO kēia ka pilikia maʻamau e hoʻoponopono ai nā ferrules: Ma hope o ka wehe ʻana, mālama lākou i kahi paʻa paʻa ma waena o nā kaula i loko o ka conductor a ʻae i ka pilina e hoʻokō i kāna manawa helu piha. ʻO nā kaula hoʻokahi e hoʻopaʻa paʻa me ka terminal. ʻO kēia hoʻopauʻana heʻoi aku ka kiʻekiʻe o ke kū'ēʻana ma mua o ka pilina ferrule pono.
ʻOi aku ka hana o nā pilina Ferrule ma mua o ka hoʻohaʻahaʻa ʻana i ke kū'ē, ʻoiai. E like me nā pili crimp ʻē aʻe, ua hoʻokau ʻia nā kaula uwea i loko o kahi ferrule i hoʻopili pono ʻia i ka puʻe nui, e kikoo axially a me ka deforming radially i ke kaʻina. ʻO nā kaula, ʻoiai ʻo ka radial compression e hoʻoneʻe i nā lewa ma waena o nā kaula.
No laila, ʻo nā hoops ke ala e hele ai no ka poʻe pāʻani ʻohana? Ma ke ʻano holoʻokoʻa, e ʻōlelo wau ʻae. Loaʻa i nā Ferrules nā pōmaikaʻi ma mua o ka uea stranded maʻamau, a ma nā noi kiʻekiʻe o kēia manawa e hoʻopili wau i ka hoʻohana ʻana iā lākou me nā terminals screw, a i ʻole nā ​​wahi āpau i ka pale kahi o ke kaumaha. hoʻomaha.Plus, hāʻawi lākou i nā papahana i kahi nānā maʻemaʻe, ʻoihana, no laila makemake wau e hoʻokomo iā lākou i loko o kaʻu mau uea stranded inā ʻaʻole koʻikoʻi ka noi. me nā ferrules like ʻole a me nā mea hana ratcheting crimping pono, ʻaʻole ia he hewa.
"He maʻalahi ka uea i hoʻopaʻa ʻia, ʻo ia kekahi o nā kumu o ka hoʻohana ʻana i ka uea stranded ma mua o ka uea paʻa i nā noi kelepona a me ka hiki ke haʻalulu."
ʻAʻohe loulou i ka kamaʻilio āu i hoʻopuka ai i kekahi mau pule i hala aku nei e pili ana i ka hoʻopili ʻana i nā ʻāpana paipu a me ka hoʻohana ʻana i nā ferrules?
Hana ʻo Phoenix Contact i kahi mea paahana maikaʻi loa e komo ana i nā makasina (e like me nā pū) i hoʻouka mua ʻia me nā ferrules o nā ʻano nui e paheʻe i loko o ka hāmeʻa.

ʻAʻole maikaʻi. Hoʻokumu ia i kahi wahi nāwaliwali ma hope koke o ka hui solder, a ʻoi aku ka nui o ke kulou ʻana i ke kaula hiki ke hōʻino i ke kaula i kēlā kiko kikoʻī.
ʻAʻole paʻa maoli ka tin, akā e hoʻololi ʻia i ka manawa. ʻO ka hopena, hiki ke wehe ʻia nā pilina i hoʻopaʻa ʻia i ka wā o ka hoʻokomo ʻana. he aha ka mea e hana nei
Hiki nō hoʻi ke komo i ka pahu i loko o ka insulation a lilo i wahi paʻakikī ma kahi mamao aku o ka pahu - inā ʻaʻole ʻoe i laki, ʻo ia kahi e hoʻomaka ai nā kaula hoʻokahi o ka uea e haki, e hōʻeha ana i nā hemahema ʻike ʻole ʻia.
ʻO ka pilikia nui, ma ka ʻoiaʻiʻo he palupalu loa ka tin a i ʻole ka hui ʻana o ke kēpau maʻamau, ʻo ke tin "kahe anuanu" mai loko mai o ka wīwī ma o ke kaʻa uila a me ke koʻikoʻi, ma hope a i ʻole e hana i ke kūpaʻa pili nui.
ʻO ke kumu ʻekolu aʻu i lohe ai e kūʻē i ke kūʻai ʻana, ʻo ia ka palupalu o ka solder a ma hope o ka manawa e hemo ai nā pilina.
ʻO ke kahe anuanu ma lalo o ke kaomi ʻo ia ke kumu e weliweli ai nā kaula mana alumini kahiko. I ka wā lōʻihi, lilo nā pilina, piʻi ke kūpaʻa + hiki i nā pilina maikaʻi ke kumu i ka arcing.
ʻAʻole au makemake e loaʻa iā ia ma ka pūnaewele. He paʻakikī a maʻalahi ka mea kūʻai aku, no laila ʻaʻole e hoʻopaʻa a paʻa ka pahu pahu e like me ke keleawe stranded palupalu. Hoʻokomo nā crimpers Ferrule i nā serrations ma ka crimp, no laila ʻoi aku ka maikaʻi ma mua o ka solder.
