Iimveliso ze-earphone, izixhobo kunye nezixhobo, i-electronics abathengi, izixhobo zasekhaya, iimveliso zokhuseleko, izixhobo ze-hi-fi, izixhobo ze-acoustic

Amandla efektri:

Iminyaka eli-13 yamava oshishino, inkampani iphumelele isatifikethi se-ISO9001, inani lezatifikethi zelungelo elilodwa lomenzi wechiza, ngaphezulu kwama-5300 abathengi abasebenzisanayo, abathengi abaninzi beenkampani ezidwelisiweyo, abasebenzi abali-106, iipuntshi ezili-12 zehardware, oomatshini bokubumba abali-18, oomatshini bokuhlanganisa abangama-26 abazenzekelayo. , 32 oomatshini bovavanyo oluzenzekelayo olupheleleyo, 21 oomatshini bokuvavanya semi-automatic, 12 oomatshini bokuvavanya ubomi kunye nezinye izixhobo zovavanyo ezingama-25

Imveliso yethu ihlangabezana nezi mfuno zingezantsi kwaye inokuphumelela olu vavanyo lungezantsi:

1) uluhlu lobushushu:sebenzisa ngaphakathi -30 ~ 70ºc

2) uluhlu olusemgangathweni lweemeko zomoya wokwenza imilinganiselo kunye neemvavanyo zilandelayo:

(1) phakathi komzimba kunye nomqhubi: 5ºc ukuya kuma-35℃

(2) phakathi kwabaqhubi ukuba bangadibanisi:45% ukuya kuma-85%

(3) uxinzelelo:86kpa ukuya kwi-106kpa

3) uxhumano kunye namandla okuqhawula

umlinganiselo uya kwenziwa emva kokudibanisa kunye nokuqhawula usebenzisa i-gauge yeplagi eqhelekileyo ngamaxesha ama-3, ukudibanisa kunye nokuqhawula amandla 5-15n

4) amandla esiphelo

umthamo ongatshintshiyo we-0.1n/m(1kgf/cm) uya kufakwa kwincam yetheminali kangangemizuzu eyi-1 kulo naliphi na icala.

akusayi kubakho monakalo kwitheminali njengokuqhekeka, ukukhululeka okanye ukudlala umbane, kwaye iimpawu zomatshini ziya kwaneliswa.

5) ukuchasana noqhagamshelwano

kulinganiswa kumsinga omncinci(100m a okanye ngaphantsi）1000hz , ukuchasana noqhagamshelwano ≤30mω

6) ukuxhathisa ukugquma

sebenzisa amandla ombane angama-500v dc kangangemizuzu eyi-1 kumacandelo alandelayo emva koko kuya kwenziwa umlinganiselo:

(1) phakathi komzimba kunye nombhexeshi

(2) phakathi kwabaqhubi ukuba bangadibanisi

(3) phakathi kwee-conductor akufuneki kubekho xa iplagi ifakiwe idc 500v 1 min insulation resistance ≥100mω

7) ukukala:dc 30v 0.2a

8) amandla e-dielectric: ac 250v ims(50~60hz) umzu o-1 wohambo lwangoku:0.5ma

(1) phakathi komzimba kunye nombhexeshi

(2) phakathi kwabaqhubi akufuneki baqhagamshelane

(3) phakathi kwabaqhubi akufuneki kubekho xa iplagi ifakiwe dc 250v 1 min

9) uvavanyo solderability

Umphezulu weetheminali uya kuthi nkxu nge-1mm kwibhafu ye-solder engama-240±5℃ kangange-3±0.5 imizuzwana.

10) ukuxhathisa iimeko zokuthengisela uvavanyo lobushushu kwakhona:

preheat: ubushushu kumphezulu wefoyile yobhedu kufuneka ifikelele 180 ℃.120s emva pcb

yangena kwisixhobo sokuthengisa.elona qondo lobushushu lide:iqondo lobushushu kumphezulu wefoyile yobhedu kufuneka lifikelele kwiqondo lobushushu eliyi-260±5℃ngemizuzwana engama-20.

11) ukuchasana nokuvavanya ukushisa kwe-solder

indlela yentsimbi yokuthambisa:

bit lobushushu 330±5℃ isicelo

ixesha lokuthambisa intsimbi3±0.5 sec

nangona kunjalo uxinzelelo olugqithisileyo aluyi kusetyenziswa kwi-terminal

13) uvavanyo lokufuma

ijack iya kugcinwa kwiqondo lobushushu

ye-40±2℃ kunye nokufuma kwe-90% ukuya kwi-96% ye-96 hr, ijekhi iya kugcinwa ikwimeko esemgangathweni ye-atmospheric ye-1 yeyure kwezinye iinkqubo.

14) uvavanyo lobushushu

IifowuniIjekhi iya kugcinwa kubushushu obuyi-70±2℃ iiyure ezingama-96,kwaye ke iya kuba phantsi kwembasurbm elawulwayo yokubuyisela

15) uvavanyo olubandayo

Ijekhi iya kugcinwa kubushushu obuyi-25±3℃ kangangeeyure ezingama-96 kwaye emva koko iya kulawulwa ziimeko zokubuyisela ezilawulwayo ngeyure enye emva koko.

16) uvavanyo lobomi

kwimeko yokukala(umthwalo non-inductive）

uqhagamshelo kunye nokuqhawulwa kuya kwenziwa imijikelo engama-5000 ngesantya esiyi-10 ukuya kuma-20 imijikelo / ngomzuzu.

17) uvavanyo lokothuka kwengqele nobushushu

Ijekhi iya kuxhomekeka kwimijikelo emi-5 yale miqathango ilandelayo iboniswe kumfanekiso, kwaye emva koko iya kubuya kwaye ivunyelwe ukuba ihlale kwindawo yegumbi kangangemizuzu engama-30..

TApha akuyi kubakho siphene okanye iintanda kwindawo ebunjiweyo.Ukufakwa&amandla okukhutshwa:3 ukuya kuma-20n

ukuxhathisa uqhagamshelwano: max.30mω

ukumelana nokugquma: min.100 mω

I-dielectric ukumelana nombane: 500vac/min(phakathi kweetheminali)
