RCA Jacks: He alakaʻi hoʻomaʻamaʻa no nā hui OEM a me ODM

Nā mea lawe nui

• RCA jackshe mau mea hoʻohui leo/wikiō wahine i hana mua ʻia e Radio Corporation of America i nā makahiki 1930.
• Hoʻohana lākou i kahi pine kikowaena 3.175 mm a me ke apo o waho 8.25 mm; Makemake ʻia ʻo 75 Ω no nā ala wikiō.
• Nā kala maʻamaukōkua laina hui: ʻulaʻula (leo ʻākau), keʻokeʻo/ʻeleʻele (leo hema), melemele (video composite), ʻalani (S/PDIF).
• Pono nā papahana hana e hōʻoia MOQ, nā mea pale, a me nā pōʻai hoʻāʻoi ka wā o ka haʻi ʻōlelo.
• Nānā maikaʻie komo pū me ka pale ʻana i ka pilina, ka pale insulation, ka ikaika hoʻokomo, a me ka nānā ʻana o RoHS.
• ʻO ke kaomi kaulahao o kēia manawa ʻo ia ka mea hana hou a me nā kauoha volume hiki ke hoʻolōʻihi i ka lawe ʻana i nā puka makani he 40 mau pule i hala.

1. Hoʻolauna

Inā kūkulu ʻoe a hoʻokumu paha i nā lako ʻike leo, e hana pū ʻoe me nā jacks RCA ma hope a i ʻole. Noho lākou ma luna o nā turntables, nā pahu hoʻonohonoho i luna, nā pedal guitar, a me nā mea hoʻāʻo. Pane kēia ʻatikala i ka nīnau "he aha nā jacks RCA"ʻoiai e hāʻawi ana i nā hui ʻenekinia i nā kikoʻī e pono ai lākou no nā kaha kiʻi, BOM, a me nā hoʻolālā kūʻai.

2. He aha nā RCA Jacks?

ʻO An Jack RCAʻo ia ka hapalua wahine o ka ʻōnaehana hoʻohui coaxial ʻelua ʻāpana, kaulike ʻole. Lawe ʻia ka hōʻailona ke kumu waena o ka jack i ka wā e pili ana ka pūpū i ka lepo. ʻO ka hapalua kāne - i kapa ʻia ʻo RCA plug - nā hoa ma ka hakakā. Hōʻike ʻia nā ʻano like ʻole ma lalo o nā inoa e like me mea hoʻohui phono, mea hoʻopili cinch, a maʻalahi paha Jack A/V.

Ma muli o ka maʻalahi o ka hoʻolālā, haʻahaʻa, a liʻiliʻi hoʻi, ua maʻa mau ia i nā mea kūʻai aku. ʻO kahi jack RCA ma kahi PCB e hahai maʻamau i kahi kapuaʻi ma waena o ka puka, ʻoiai aia nā ʻāpana mauna i luna no nā laina kau kiʻekiʻe.

3. He Moolelo Pokole

4. Anatomy a me na mea nui

4.1 Nā hiʻohiʻona mīkini

Hoʻololi nā koho waiwai i ke kumukūʻai a me ka hana. ʻO ke keleawe me ka nickel hana no nā hana komo; ʻO ke keleawe keleawe me 15 µin gula e kūʻē i ka oxidation ma nā SKU premium.

4.2 Kiʻi Uila

• ʻO kēia manawa: a hiki i ka 1 A ma 12 V DC (hoʻohana mea kūʻai maʻamau).
• Hoʻopili kūʻē: 30 mΩ mua, 80 mΩ ma hope o ka ho'āʻo ola.
• Kūleʻa hoʻokaʻawale: ≥100 MΩ ma 500 V DC.
• E kū i ka uila: 500 V AC no 60 s.
• Ka hoʻopalekana:

• Leo: ʻaʻole i hoʻopaʻa ʻia, maʻamau 50–100 Ω.
• Composite a i ʻole S/PDIF: pahuhopu 75 Ω; pae pinepine ʻia nā ʻāpana honua ma kahi kokoke i 45–60 Ω ma muli o nā palena geometry.

ʻO nā pūpū pā lahilahi a ʻoi aku ka paʻa o ka dielectric spacing e hoʻomaikaʻi i ka impedance maoli akā hoʻohui i ke kumukūʻai.

5. Hoʻopili kala a me nā kuleana hōʻailona

I ka wā e kūkulu ʻia ai ka laina, pale nā kala like i ka hui ʻana a kōkua i nā hui nānā e hopu koke i nā hewa.

6. Nā Lae Hana Hana a me ka Hoʻolako

6.1 MOQ a me nā mea hana

Hoʻomaka pinepine nā kapuaʻi maʻamau i 1,000-5,000 pcs. Hiki ke hoʻokuʻu i ka MOQ ma luna o 10,000 pcs i ka mea hoʻohana i nā mea hana hou a me ka ʻokiʻoki. Hoʻouna pinepine ʻia nā laʻana mua i ʻelua pule ma hope o PO; pono nā mea paʻahana paʻakikī hou elima a ʻeono pule.

6.2 Lead-Time Drift

ʻO nā kumu kūʻai keleawe, nā ʻauwaʻa galvanic plating, a me ka congestion port e hoʻohui i ka maopopo ʻole. Nui nā mea kūʻai aku i kēia manawa i nā kauoha blanket ʻeono a ʻewalu mau mahina ma mua e laka i ka manawa slot. Inā makemake ʻoe i kahi ʻōpala hou, e hoʻopaʻa i ka papahana ma kahi mahina ʻē aʻe.

6.3 Nā ʻanuʻu maikaʻi

1. Ke komo mai nei: X-ray plating mānoanoa, plastic resin palapala hōʻoia.
2. I ka hana: ʻAna anawaena pine, hoʻāʻo ikaika hoʻokomo i kēlā me kēia neʻe.
3. Puhi-i: 500 pōʻai pōʻaiapili / wehe i ka laʻana hailona.
4. hope loa: Hoʻomau ka nānā ʻana, kiʻekiʻe-pot, optics no nā niho.
5. Hoʻokō: RoHS, REACH, a me nā noi kikoʻī o nā mea kūʻai aku.
6. RCA Jack vs. Nā mea hoʻohui ʻē aʻe

Hoʻomaka ka RCA ma kahi e kū ai ke kumukūʻai a me ka ʻike ma luna o ka bandwidth. No ka holo lōʻihi a i ʻole impedance koʻikoʻi, lanakila ka BNC a i ʻole XLR.

8. Nā ho'āʻo maikaʻi ma ka kikoʻī

E palapala i kēia mau laina i ka hoʻolālā hoʻomalu i kaʻana like ʻana o ka hui QC o ka hale hana a me kāu poʻe loiloi i hoʻokahi ʻōlelo.

9. Manaʻo kōkua no nā hui papahana

• E kaʻana like i ke kikoʻī pili pili. ʻAʻole hiki ke hoʻopaʻa ʻia kahi jack i hoʻopaʻa ʻia no kahi kaula Hi-Fi lohi i kahi puʻupuʻu leo kaʻa.
• Laka i ka papa mua. ʻO ka hoʻololi ʻana i ka nickel no ke gula ma hope o ka papa kuhikuhi e kono mai i ka hoʻokō hou ʻana.
• E noi i nā ʻāpana impedanceinā hele nā hōʻailona wikiō a i ʻole S/PDIF i 10 kapuaʻi.
• E nānā i ka hoʻopili ʻana(tape-and-reel, tray, or bulk) e kūpono me SMT a i ʻole nā laina nalu.
• E mālama i kahi pahu laʻana gulai loko o ke keʻena hana; e holo i ka plug-fit spot checks ke hiki mai na mele.
