IiJacks zeRCA: Isikhokelo esiSebenzayo se-OEM kunye namaQela e-ODM
Izinto eziphambili zokuThatha
- Iijacks zeRCAziziqhagamshelo zeaudio/ zevidiyo ezaveliswa okokuqala yiRadio Corporation yaseMelika ngeminyaka yoo-1930.
- Basebenzisa i-pin ye-3.175 mm yeziko kunye ne-8.25 mm yangaphandle; 75 Ω ikhethwa kwiindlela zevidiyo.
- Imibala eqhelekileyoimigca yokuhlanganisa uncedo: obomvu (umsindo ochanekileyo), omhlophe / omnyama (umsindo osekhohlo), umthubi (ividiyo edibeneyo), i-orange (S / PDIF).
- Iiprojekthi zokuvelisa kufuneka ziqinisekise MOQ, imathiriyeli yokucola, kunye nemijikelo yovavanyongexesha lekowuteshini.
- Iitshekhi zomgangathozibandakanya ukumelana noqhagamshelwano, ukumelana nokugquma, amandla okufaka, kunye nokuhlolwa kweRoHS.
- Uxinzelelo lwangoku lonikezelo luthetha isixhobo esitsha kunye neodolo yevolumu inokolula ukuhanjiswa kweefestile kwiiveki ezingama-40 ezidlulileyo.
- Intshayelelo
Ukuba uyakha okanye uvelisa ihardware yeaudio-visual, uya kusebenza ngeejacks zeRCA kungekudala okanye kamva. Bahlala kwii-turntables, ii-set-top boxes, iipedali zesiginci, kunye nezixhobo zokuvavanya. Eli nqaku liphendula umbuzo othi “yintoni iijacks zeRCA” ngelixa enika amaqela obunjineli iinkcukacha ezifunekayo kwimizobo, ii-BOM, kunye nezicwangciso zokuthenga.
- Yintoni iiJacks zeRCA?
An I-RCA jacksisiqingatha sowesifazane secandelo elibini, inkqubo yokudibanisa i-coaxial engalinganiyo. Isokethi esembindini kajack ithwala umqondiso ngelixa iqokobhe libophelela emhlabeni. Isiqingatha sendoda-esibizwa ngokuba yi-RCA plug-amaqabane ngokukhuhlana. Ukwahluka kuvela phantsi kwamagama anje isinxibelelanisi sephono, cinch isinxibelelanisi, okanye ngokulula Ijekhi yeA/V.
Ngenxa yokuba uyilo lulula, lunexabiso eliphantsi, kwaye luncinci, luhlala luxhaphakile kwizixhobo zabathengi. Ijekhi ye-RCA kwi-PCB idla ngokulandela umngxuma wokuhamba komngxuma, nangona iindawo eziphezu komhlaba zikhona kwimigca yokubeka enesantya esiphezulu.
- Imbali emfutshane
| Unyaka | Isiganeko esibalulekileyo | Phawula |
| 1937 | Ukusetyenziswa kokuqala kwangaphakathi kwi-RCA U-109 irediyo/igramafoni | Iingcali zenkonzo zinokukhupha iimodyuli ngaphandle kwe-soldering |
| 1940s | Iijekhi zephaneli yangasemva koonomathotholo betabletop | Kuvunyelwe abathengi ukuba baqhoboshele abadlali berekhodi bangaphandle |

- I-Anatomy kunye neNgcaciso eziphambili
4.1 Iimpawu zoomatshini
| Uphawu | Ixabiso eliqhelekileyo | Injongo |
| Isikhonkwane esisembindini Ø | 3.175 mm | Ithwala umqondiso |
| Iqokobhe Ø | 8.25 mm | Umhlaba kunye nekhaka |
| Intambo enkulu Ø | 7 mm | Yamkela i-coax eqhelekileyo |
| Imijikelo yokukhwelana | 100–5,000 | Ibakala lokuqina |
| Amandla okukhwelana | 0.5–3 kgf | Ukuziva komsebenzisi + umqondiso wemfezeko |
Izinto eziphathekayo zinefuthe kwiindleko kunye nokusebenza. Ibrass ene-nickel isebenza kwimisebenzi yenqanaba lokungena; ialloyi yobhedu ene-15 µin yegolide ixhathisa i-oxidation kwii-SKU zeprimiyamu.
4.2 Amanani oMbane
- Okwangoku: ukuya kuthi ga kwi-1 A kwi-12 V DC (ukusetyenziswa komthengi oqhelekileyo).
- Ukuchasana noqhagamshelwano: 30 mΩ yokuqala, 80 mΩ emva kovavanyo lobomi.
- Ukumelana ne-insulation: ≥100 MΩ kwi-500 V DC.
- Ukumelana nombane: I-500 V AC ye-60 s.
- Impedance:
- Umsindo: awuchazwanga ngokuqinileyo, idla ngokuba yi-50–100 Ω.
- I-Composite okanye i-S/PDIF: ithagethi 75 Ω; iindawo zehlabathi lokwenyani zihlala kufutshane ne-45–60 Ω ngenxa yemida yejometri.
Amaqokobhe anodonga olucekeceke kunye nesithuba esiqinileyo se-dielectric siphucula i-impedance yokwenyani kodwa yongeza iindleko.
- Ukufakwa kweKhowudi yoMbala kunye neendima zoMqondiso
| Umbala | Ukusetyenziswa okuPhambili | Amanqaku awongezelelweyo |
| Bomvu | Isandi sejelo lasekunene | Njalo zidibaniswe nomhlophe okanye omnyama |
| Mhlophe / Mnyama | Isandi setshaneli yasekhohlo | Umnyama ubonakala kwimigca ethile yemveliso yaseAsia |
| Lubhelu | Ividiyo ehlanganisiweyo | PAL/NTSC SD indlela yevidiyo |
| Orenji | Isandi sedijithali S/PDIF | 0.5 V pp coax spec |
| Luhlaza | Y (luma) icandelo | HD ekwaziyo |
| Luhlaza | Pb (Cb) icandelo |
|
| Bomvu | Pr (Cr) icandelo | Wabelana ngombala weqokobhe kunye nesandi esilungileyo-leyibhile iindawo ngokucacileyo |
Ngexesha lokwakhiwa komgca, imibala ehambelanayo ithintela ukuxubana kwaye inceda amaqela okuhlola ukubamba iimpazamo ngokukhawuleza.
- Iindawo zokuVelisa kunye neeNgcaciso zoBonelelo
6.1 MOQ kunye nezixhobo
Imizila yeenyawo esemgangathweni ihlala iqala 1,000-5,000 iipcs. Iplating ekhethekileyo, i-engile, okanye umbala unokutyhala i-MOQ ngaphezulu kwe-10,000 iipcs njengoko umzi-mveliso unciphisa izixhobo kunye nokulungisa. Iisampulu zokuqala zidla ngokuthunyelwa kwiiveki ezimbini emva kwePO; izixhobo ezinzima kufuneka ezinye iiveki ezintlanu ukuya ezintandathu.
6.2 I-Lead-Time Drift
Amaxabiso obhedu, iindawo zokubeka i-galvanic, kunye nokuxinana kwezibuko zongeza ukungaqiniseki. Abathengi abaninzi ngoku bafaka iiodolo zengubo kwiinyanga ezintandathu ukuya kwezisibhozo ngaphambili ukuze batshixe ixesha lokuvala. Ukuba ufuna isikhunta esitsha, lungisa ishedyuli ngenye inyanga.
6.3 Amanyathelo asemgangathweni
- Okungenayo: X-ray plating ubukhulu, iplastiki resin yokukhangela isatifikethi.
- Kwinkqubo: I-Pin yegeyiji yedayamitha, uvavanyo lwamandla okufakwa kwishifti nganye.
- Ukutshiswa-ngaphakathi: Iplagi ye-500 ye-cycle / unplug kwiqashiso lesampuli.
- Okokugqibela: Ukuqhubeka nokuskena, imbiza ephezulu, i-optics yamazinyo.
- Ukuthobela: RoHS, REACH, kunye naziphi na izicelo ezijoliswe kumthengi.
- RCA Jack vs. Ezinye iziqhagamshelo
| Isidibanisi | Ubume boMqondiso | Ukutshixa | Umgama omKhulu (uchwethezo.) | Iindleko zeYunithi (ubuninzi) |
| RCA | Ukungalungelelani | Ukukhuhlana | 2–3 m yomsindo | Phantsi |
| XLR | Ilungelelene | Latch | I-100 m+ yomsindo | Mid |
| I-BNC | 75 Ω | Ibhayonet | 50 m SDI | Mid |
| 3.5 mm TRS | Ukungalungelelani | Ukukhuhlana | 1–2 m | Isezantsi kakhulu |
I-RCA ikhanya apho ixabiso kunye nokuqhelana kuhlala ngaphezu kwe-bandwidth. Ukuqhuba ixesha elide okanye ukuthintela okungqongqo, iBNC okanye iXLR iyaphumelela.
- Iimvavanyo zoMgangatho ngokweNkcukacha
| Uvavanyo | Indlela | Dlula umda | Isizathu Sokuba Kubalulekile |
| Ukuchasana noqhagamshelwano | 20 mV, 100 mA ezine-wire | ≤30 mΩ | Ilahleko ephantsi |
| Ukumelana ne-insulation | I-500 VDC, i-1 min | ≥100 MΩ | Thintela unxibelelwano |
| Amandla e-Dielectric | 500 V AC, 60 s | Akukho flashover | Ukhuseleko |
| Izinyo letyuwa | iiyure ezingama-48, 5% NaCl | Akukho mhlwa obomvu | Izixhobo zaselwandle / zemoto |
| Imijikelo yokukhwelana | Isixhobo esinemoto | Akukho plating igugile | Ukuqina |
Bhala le migca kwisicwangciso solawulo ukuze iqela le-QC lomzi-mveliso kunye nabaphicothi-zincwadi babelane ngolwimi olunye.
- Iingcebiso zokufumana amaQela eProjekthi
- Yabelana ngeplagi yokukhwelana. Ijekhi elungiselelwe intambo ye-Hi-Fi ebhityileyo ayinakubamba iplagi yemoto evakalayo.
- Tshixa iplating kwangethuba. Ukutshintshela i-nickel yegolide emva kwexesha kwishedyuli kumema ukufaneleka.
- Buza iiploti ze-impedanceukuba ividiyo okanye iimpawu ze-S/PDIF ziwela i-10 ft.
- Jonga ukupakishwa(itheyiphu-ne-reel, itreyi, okanye isambuku) ukuze ilingane ne-SMT okanye imigca yamaza.
- Gcina ikiti yesampulu yegolideelebhu; sebenzisa ii-plug-fit spot checks xa iireels zifika.
- FAQ
- Kutheni ividiyo yam i75 Ω ngamanye amaxesha ilinganisa ngaphantsi kwe60 Ω kwijekhi yeRCA?
