HFJV1-2450RLMe ka LED 1×1 Vertical 10/100BASE-THoʻohui RJ45

Hiki ke hoʻokaʻawale ʻia nā hana kumu o ka mea hoʻohui i ʻekolu mau ʻāpana: ka hana mechanical, ka hana uila a me ka hana kaiapuni.
2, hana uila
ʻO nā hana uila nui o ka mea hoʻohui e pili ana i ka paʻi paʻi, ka pale insulation a me ka ikaika dielectric.Pili nui nā hana uila i nā mākau electroplating.ʻOiaʻiʻo, hilinaʻi nui nā mea hoʻohui i ka hopena conduction o ka papa conductive waho.
①Hoʻopā i ke kūʻē.Pono nā mea hoʻopili uila kiʻekiʻe me ka haʻahaʻa a me ke kūpaʻa paʻa.ʻO ke kūpaʻa hoʻopā o ka mea hoʻohui mai kahi mau milliohms a i ʻumi miliohms.I kēia manawa, ʻo ia ka nui o ke kūʻē ʻana o ka uhi ʻili.
②Ka pale ʻana i ka insulation.ʻO ka pahuhopu o ke ana ʻana i ka hana insulation ma waena o nā ʻāpana hoʻopā o ka mea hoʻopili uila a ma waena o ka ʻāpana paʻi a me ka pūpū, ʻo ke ʻano o ka nui mai nā haneli megohms a i kekahi mau tausani megohms.
③ Ka ikaika uila.ʻIke pū ʻia ʻo ia ʻo ke kūpaʻa kūpaʻa a me ka dielectric withstand voltage, hōʻike ia i ka hiki ke kū i nā voltage hoʻāʻo hou ma waena o nā ʻāpana hoʻopā o ka mea hoʻohui a i ʻole ma waena o nā ʻāpana pā a me ka pūpū.
④ Nā hana uila ʻē aʻe.ʻO ka electromagnetic interference leakage attenuation ka loiloi ʻana i ka hopena pale pale electromagnetic interference o ka mea hoʻohui, a hoʻāʻo maʻamau ia ma ke alapine o 100MHz ~ 10GHz.
No nā mea hoʻohui coaxial radio frequency, aia kekahi mau pahuhopu uila e like me ka impedance hiʻohiʻona, ka nalowale o ke komo ʻana, ka coefficient noʻonoʻo, a me ka ratio kū ʻana o ka hawewe (VSWR).Ma muli o ka hoʻomohala ʻana i nā mākau kikohoʻe, i mea e hoʻopili ai a hoʻouna i nā hōʻailona pulse kikohoʻe kiʻekiʻe, hōʻike ʻia kahi ʻano mea hoʻohui hou, ʻo ia hoʻi ka mea hoʻohui hōʻailona kiʻekiʻe.No laila, i nā ʻōlelo o nā hana uila, ma kahi o ka impedance hiʻohiʻona, hōʻike ʻia kekahi mau pahuhopu uila hou., E like me crosstalk (crosstalk), hoʻopaneʻe hoʻouna (delay), lag manawa (skew) a pēlā aku.
