RCA Jacks: Chitsogozo Chothandiza cha Magulu a OEM ndi ODM

Zofunika Kwambiri

• Zithunzi za RCAndi zolumikizira zachikazi / makanema zomwe zidayamba kupangidwa ndi Radio Corporation of America m'ma 1930s.
• Amagwiritsa ntchito pini yapakati ya 3.175 mm ndi mphete yakunja ya 8.25 mm; 75 Ω imakondedwa pamakanema amakanema.
• Mitundu yokhazikikamizere yothandizira: yofiira (yomvera kumanja), yoyera / yakuda (yomvera yakumanzere), yachikasu (kanema wamagulu), lalanje (S/PDIF).
• Ntchito zopanga ziyenera kutsimikiziridwa MOQ, plating zakuthupi, ndi miyeso yoyesererapa siteji ya mawu.
• Macheke abwinokuphatikiza kukana kukhudzana, kukana kutsekereza, kuyika mphamvu, ndi kuwunika kwa RoHS.
• Kupanikizika kwaposachedwa kwapaintaneti kumatanthauza zida zatsopano kuphatikiza ma voliyumu amatha kutambasula mawindo apitawa masabata 40.

1. Mawu Oyamba

Ngati mupanga kapena kupanga zida zowonera, mudzagwira ntchito ndi ma jacks a RCA posachedwa. Amakhala pa ma turntables, mabokosi apamwamba, ma gitala, ngakhale zida zoyesera. Nkhaniyi ikuyankha funso lakuti “ma RCA jacks ndi chiyani” popatsa magulu a uinjiniya tsatanetsatane wa zojambula, ma BOM, ndi mapulani ogula.

2. Kodi ma RCA Jacks ndi chiyani?

An Chithunzi cha RCAndi theka lachikazi la magawo awiri, osagwirizana ndi coaxial cholumikizira. Soketi yapakati ya jack imanyamula chizindikiro pomwe chipolopolocho chimamangirira pansi. Theka lachimuna-lotchedwa RCA plug-anzako mwa kukangana. Zosiyanasiyana zimawonekera pansi pa mayina monga cholumikizira phono, cholumikizira cha cinch, kapena mophweka A/V jack.

Chifukwa mapangidwe ake ndi osavuta, otsika mtengo, komanso ochepa, amakhalabe ofala pamagetsi ogula. Jack wa RCA pa PCB nthawi zambiri amatsata njira yodutsa-bowo, ngakhale kuti mbali zokwera pamwamba zimakhalapo pamizere yothamanga kwambiri.

3. Mbiri Yachidule

4. Anatomy ndi Zofunika Kwambiri

4.1 Mawonekedwe a Makina

Zosankha zakuthupi zimakhudza mtengo ndi magwiridwe antchito. Brass yokhala ndi faifi tambala imagwira ntchito zolowera mulingo; aloyi yamkuwa yokhala ndi 15 µin golide imakana oxidation pa ma SKU apamwamba.

4.2 Zithunzi Zamagetsi

• Panopa: mpaka 1 A pa 12 V DC (kugwiritsa ntchito ogula).
• Kulimbana ndi kukana: 30 mΩ koyambirira, 80 mΩ pambuyo poyesedwa moyo.
• Insulation resistance: ≥100 MΩ pa 500 V DC.
• Kulimbana ndi magetsi: 500 V AC kwa 60 s.
• Kusokoneza:

• Zomvera: sizinatchulidwe mwamphamvu, nthawi zambiri 50-100 Ω.
• Zophatikizika kapena S/PDIF: chandamale 75 Ω; madera enieni a dziko nthawi zambiri amakhala pafupi ndi 45–60 Ω chifukwa cha malire a geometry.

Zipolopolo zamakhoma zoonda komanso malo ocheperako a dielectric amapangitsa kuti pakhale vuto lenileni koma amawonjezera mtengo.

5. Ma Coding amitundu ndi Maudindo a Signal

Pakupanga mizere, kufananitsa mitundu kumalepheretsa kusakanikirana ndikuthandiza magulu owunikira kuti azindikire zolakwika mwachangu.

6. Kupanga ndi Supply Chain Points

6.1 MOQ ndi Zida

Mipando yokhazikika nthawi zambiri imayambira pa 1,000-5,000 ma PC. Kuyika kwapadera, ngodya, kapena mtundu ukhoza kukankhira MOQ pamwamba pa ma PC 10,000 pamene fakitale imapanga zida zatsopano ndi kudula. Zitsanzo zoyamba zimatumiza masabata awiri pambuyo pa PO; zida zolimba zimafunika milungu ina isanu kapena isanu ndi umodzi.

6.2 Kuthamanga Kwanthawi Yotsogola

Mitengo yamkuwa, mipata ya galvanic plating, ndi kuchulukana kwa madoko kumawonjezera kusatsimikizika. Ogula ambiri tsopano amayitanitsa mabulangete miyezi isanu ndi umodzi mpaka eyiti kuti atseke nthawi yotsekera. Ngati mukufuna nkhungu yatsopano, sungani ndondomekoyi mwezi wina.

6.3 Njira Zabwino

1. Obwera: X-ray plating makulidwe, pulasitiki utomoni satifiketi cheke.
2. Zili mkati: Pin diameter gauge, kuyika mphamvu kuyesa kusintha kulikonse.
3. Kuwotcha mkati: 500 cycle plug / unplug pa zitsanzo zambiri.
4. Chomaliza: Kusanthula mosalekeza, mphika wapamwamba, ma optics a mano.
5. Kutsatira: RoHS, REACH, kuphatikiza zopempha zilizonse zokhudzana ndi kasitomala.
6. RCA Jack vs. Zolumikizira Zina

RCA imawala pomwe mtengo ndi kuzolowera kumakhala pamwamba pa bandwidth. Kwa nthawi yayitali kapena kulepheretsa mwamphamvu, BNC kapena XLR imapambana.

8. Mayeso a Ubwino Mwatsatanetsatane

Lembani mizere iyi mu dongosolo lowongolera kuti gulu la QC la fakitale ndi owerengera anu azigawana chilankhulo chimodzi.

9. Malangizo Othandizira Magulu a Ntchito

• Gawani mapulagi a mating. Jack wokongoletsedwa ndi chingwe chaching'ono cha Hi-Fi mwina sangagwire pulagi yagalimoto yamawu.
• Tsekani plating molawirira. Kusinthanitsa nickel ndi golidi mochedwa mu dongosolo kumapangitsa kuti munthu ayenererenso.
• Funsani ziwembu za impedancengati kanema kapena S/PDIF zizindikiro kuwoloka 10 ft.
• Onani zoyikapo(tepi-ndi-reel, tray, kapena zochuluka) kuti zigwirizane ndi SMT kapena mizere yoweyula.
• Khalani ndi zida zagolidemu labu; yendetsani macheke a plug-fit malo akafika ma reel.
