RCA Jacks: Iyo Inoshanda Inotungamira yeOEM uye ODM Matimu
Key Takeaways
- RCA jacksndeechikadzi odhiyo / vhidhiyo yekubatanidza yakatanga kugadzirwa neRadio Corporation yeAmerica kuma1930s.
- Vanoshandisa pini yepakati 3.175 mm uye mhete yekunze ye8.25 mm; 75 Ω inosarudzwa nzira dzevhidhiyo.
- Standard mavaramitsara yegungano rekubatsira: tsvuku (kurudyi odhiyo), chena/dema (kuruboshwe odhiyo), yero (vhidhiyo inoumbwa), orenji (S/PDIF).
- Mapurojekiti ekugadzira anofanirwa kusimbisa MOQ, plating zvinhu, uye bvunzo kutendererapanguva yekotesheni.
- Kuongorora kwehutanosanganisira kuramba kubata, kudzivirira kumisa, simba rekuisa, uye RoHS kuongorora.
- Ikozvino kugovera-cheni kudzvanywa kunoreva kutsva kwekushandisa uye vhoriyamu maodha anogona kutambanudza kuburitsa windows mavhiki makumi mana apfuura.
- Nhanganyaya
Kana iwe ukavaka kana kuburitsa odhiyo-inotaridzika hardware, iwe uchashanda neRCA jacks munguva pfupi kana gare gare. Vanogara pamaturntables, set-top boxes, gitare pedals, uye even test gear. Ichi chinyorwa chinopindura mubvunzo "chii chinonzi RCA jacks” uku vachipa zvikwata zveinjiniya ruzivo rwavanoda kudhirowa, maBOM, uye zvirongwa zvekutenga.
- Chii chinonzi RCA Jacks?
An RCA jackndiyo hafu yechikadzi yezvikamu zviviri, isina kuenzana coaxial connector system. Iyo jack's center socket inotakura chiratidzo apo goko rinosungirira pasi. Hafu yechirume-inonzi RCA plug-vakaroorana nekukakavadzana. Variants vanoonekwa pasi pemazita akadai phono connector, cinch connector, kana kuti zviri nyore A/V jekiseni.
Nekuti dhizaini iri nyore, yakaderera-mutengo, uye diki, inoramba yakajairika mugiya revatengi. Iyo RCA jack paPCB inowanzo tevera kuburikidza-gomba tsoka, kunyange nzvimbo-yepamusoro-soro zvikamu zviripo kune yakakwirira-kumhanya yekuisa mitsetse.

Sarudzo dzezvinhu zvinopesvedzera mutengo nemashandiro. Brass ine nickel inoshanda yekupinda-level mabasa; alloy yemhangura ine 15 µin goridhe inopikisa oxidation pane ekutanga SKUs.
4.2 Magetsi Figures
- Current: kusvika ku1 A pa12 V DC (yakajairika kushandiswa kwevatengi).
- Bata kuramba: 30 mΩ kutanga, 80 mΩ mushure mekuedzwa kwehupenyu.
- Insulation resistance: ≥100 MΩ pa500 V DC.
- Kushingirira voltage: 500 V AC ye60 s.
- Impedance:
- Odhiyo: haina kutaurwa zvakasimba, kazhinji 50–100 Ω.
- Composite kana S/PDIF: chinangwa 75 Ω; nzvimbo dzepasirese dzinowanzomhara padyo ne45–60 Ω nekuda kwemiganhu yejometri.
Matete-madziro mabhomba uye yakasimba dielectric spacing inovandudza impedance chaiyo asi wedzera mutengo.
- Ruvara Coding uye Signal Mabasa
| Color | Primary Kushandisa | Extra Notes |
| Tsvuku | Kurudyi-chiteshi audio | Nguva dzose yakabatanidzwa nemuchena kana dema |
| Muchena / Mutema | Kuruboshwe-chiteshi audio | Dema rinoonekwa pane mamwe maAsia chigadzirwa mitsara |
| Yero | Composite vhidhiyo | PAL/NTSC SD vhidhiyo nzira |
| Orenji | S/PDIF digital audio | 0.5 V pp coax spec |

| Tsvuku | Pr (Cr) chikamu | Inogovanisa ruvara rweganda nerunyoro rwekurudyi - nyora zvikamu zvakajeka |
Panguva yekugadzira mitsara, mavara anoenderana anodzivirira kusanganiswa uye anobatsira zvikwata zvekuongorora kubata kukanganisa nekukurumidza.
- Manufacturing and Supply Chain Points
6.1 MOQ uye Tooling
Mitsipa yetsoka inowanzotanga pa 1,000–5,000 pcs. Yakasiyana-siyana plating, kona, kana ruvara inogona kusunda MOQ pamusoro 10,000 pcs sezvo fekitori inogadzirisa zvishandiso zvitsva uye kucheka. Masampuli ekutanga anowanzo kutumira mavhiki maviri mushure mePO; midziyo yakaoma inoda mamwe mavhiki mashanu kusvika matanhatu.
6.2 Kutungamira-Nguva Drift
Mitengo yemhangura, galvanic plating slots, uye congestion yechiteshi inowedzera kusagadzikana. Vatengi vazhinji vava kuisa maodha egumbeze mwedzi mitanhatu kusvika misere pamberi kuti vavhare slot nguva. Kana iwe uchida mold itsva, gadzirisa purogiramu nemumwe mwedzi.
6.3 Hunhu Matanho
- Incoming: X-ray plating ukobvu, epurasitiki resin chitupa cheki.
- In-process: Pin dhayamita geji, yekuisa simba kuyedza shanduko yega yega.
- Kusvirwa: 500 cycle plug / unplug pane sampuli yakawanda.
- Final: Kuenderera mberi scan, high-pot, optics yemazino.
- Kuteerera: RoHS, REACH, pamwe nechero mutengi-zvakananga zvikumbiro.
- RCA Jack vs. Zvimwe Zvibatanidza
| Connector | Signal Nature | Kukiya | Max Distance (taipa.) | Mutengo Weyuniti (yakawanda) |
| RCA | Unbalanced | Friction | 2–3 m odhiyo | Low |
| XLR | Balanced | Latch | 100 m+ odhiyo | Mid |
| BNC | 75 Ω | Bayonet | 50 m SDI | Mid |
| 3.5 mm TRS | Unbalanced | Friction | 1–2 m | Yakaderera kwazvo |
RCA inopenya uko mutengo uye kujairana kunogara pamusoro pe bandwidth. Kwekumhanya kwenguva refu kana kuomesera impedance, BNC kana XLR inohwina.
