Imikhiqizo yama-earphone, amathuluzi nezinto zokusebenza, izinto zikagesi zabathengi, izinto zikagesi zasendlini, imikhiqizo yokuvikela, okokusebenza kwe-hi-fi, okokusebenza kwe-acoustic

Amandla efekthri:

Ineminyaka engu-13 yesipiliyoni sembonini, inkampani isiphasile isitifiketi se-ISO9001, izitifiketi eziningi zelungelo lobunikazi, amakhasimende asebenzisanayo angaphezu kuka-5300, amakhasimende amaningi ezinkampani ezisohlwini, abasebenzi abayi-106, izibhakela zehardware eziyi-12, imishini yokubumba imijovo eyi-18, imishini yokuhlanganisa ezenzakalelayo engama-26 egcwele. , imishini yokuhlola ezenzakalelayo engama-32, imishini yokuhlola i-semi-automatic engama-21, imishini yokuhlola impilo eyi-12 kanye nezinye izinto zokuhlola ezingama-25

Umkhiqizo wethu uhlangabezana nezidingo ezingezansi futhi ungaphumelela lezi zivivinyo ezingezansi:

1) izinga lokushisa:sebenzisa ngaphakathi -30 ~ 70ºc

2) ububanzi obujwayelekile bezimo zomkhathi zokwenza izilinganiso nokuhlola bumi kanje:

(1) phakathi komzimba nomqhubi: 5ºc kuya ku-35℃

(2) phakathi kwabaqhubi akufanele baxhumane:45% ukuya ku-85%

(3) ingcindezi:86kpa ukuya ku-106kpa

3) amandla okuxhuma kanye nokunqamula

ukulinganisa kuzokwenziwa ngemuva kokuxhuma nokunqanyulwa kusetshenziswa i-plug gauge ejwayelekile izikhathi ezi-3, ukuxhuma kanye namandla okunqamula 5-15n

4) amandla esiphetho

umthwalo omile ongu-0.1n/m(1kgf/cm) uzosetshenziswa ekugcineni kwetheminali iminithi elingu-1 kunoma iyiphi indlela .

angeke kube khona umonakalo kutheminali njengokuqhekeka, ukuxega noma ukudlala ugesi, futhi izici zemishini zizokwaneliswa.

5) ukumelana nokuxhumana

kulinganiswa kumanje omncane(100m noma ngaphansi）1000hz , ukumelana nokuxhumana ≤30mω

6) ukumelana nokwahlukanisa

sebenzisa i-voltage engu-500v dc iminithi elingu-1 ezingxenyeni ezilandelayo ngemva kwalokho okuzokwenziwa ukukala:

(1) phakathi komzimba nomkhondakta

(2) phakathi kwabaqhubi akufanele baxhumane

(3) phakathi kwama-conductor akufanele kube lapho ipulaki ifakiwe i-dc 500v 1 min insulation resistance ≥100mω

7) isilinganiso:dc 30v 0.2a

8) amandla e-dielectric:ac 250v ims(50~60hz) iminithi elingu-1 lohambo lwamanje:0.5ma

(1) phakathi komzimba nomkhondakta

(2) phakathi kwama-conductor akufanele axhumane

(3) phakathi kwamakhondaktha akufanele kube lapho ipulaki ifakiwe dc 250v 1 min

9) ukuhlolwa solderability

ingaphezulu lamatheminali lizocwiliswa ngo-1mm kubhavu we-solder ongu-240±5℃ imizuzwana engu-3±0.5

10) ukumelana nezimo ze-soldering zokuhlola ukushisa kabusha kwe-solder:

preheat: izinga lokushisa phezu ucwecwe zethusi surface kufanele sifinyelele 180 ℃.120s ngemva pcb

yangena emishinini yokuhlanganisa.izinga lokushisa eliphakeme kunawo wonke: izinga lokushisa endaweni ye-copper foil kufanele lifinyelele izinga lokushisa eliphakeme elingu-260±5℃ ngemizuzwana engu-20.

11) ukumelana nokuhlolwa kokushisa kwe-solder

Indlela ye-Soldering iron:

izinga lokushisa elincane 330±5℃ isicelo

isikhathi sokugcwalisa i-iron3±0.5 sec

nokho ukucindezela okukhulu akumele kusetshenziswe kutheminali

13) ukuhlolwa komswakama

ujeke uzogcinwa ezingeni lokushisa

ka-40±2℃ kanye nomswakama ongu-90% kuya ku-96% amahora angu-96, khona-ke ujeke uzogcinwa usesimweni esijwayelekile somoya ihora elingu-1 kwezinye izinqubo.

14) ukuhlolwa kokushisa

Iifoniujeke uzogcinwa ezingeni lokushisa elingu-70±2℃ amahora angama-96,futhi emva kwalokho izofakwa ngaphansi kwembasurbm yokutakula elawulwayo

15) ukuhlolwa okubandayo

ujeke uzogcinwa ekushiseni okungama-25±3℃ amahora angama-96 bese ubekwa ngaphansi kwezimo ezilawulwayo zokuthola kabusha ihora elingu-1 ngemuva kwalokho.

16) ukuhlolwa kwempilo

esimweni sokulinganisa(umthwalo ongenayo inductive）

uxhumano kanye nokunqanyulwa kuzokwenziwa 5000 imijikelezo ngesivinini 10 ukuze 20 imijikelezo / min.

17) ukuhlolwa kokushaqeka okubandayo nokushisa

ujeke uzobhekana nemijikelezo emi-5 yalezi zimo ezilandelayo ezikhonjiswe emfanekisweni, bese ibuya futhi ivunyelwe ukuhlala esimweni segumbi imizuzu engama-30..

Tlapha ngeke kube khona ukuwohloka noma imifantu engxenyeni ebunjiwe.Ukufakwa&amandla okukhipha:3 kuya ku-20n

ukumelana nokuxhumana: max.30mω

ukumelana nokwahlukanisa: min.100 mω

I-dielectric withstanding voltage: 500vac/min(phakathi kwamatheminali)
