Edge Connector Bevelling: Chii Chayo, Nei Chichidiwa, uye Angle Yakakodzera Bevel

Kukwesha chinobatanidza chemucheto ndiko kukwesha chinobatanidza chemupendero weminwe yegoridhe yePCB kuitira kuti bhodhi ritsvedzerere zvakanaka musokisi rine makadhi pasina kubaya, kukwesha, kana kukuvadza minwe yacho. Inzira diki yekupedzisa ine mhedzisiro huru pakuvimbika kwekuisa uye hupenyu hwekubatana. Gwaro iri rinotsanangura kuti kukwesha chii, nei kuchidikanwa, makona akafanana e bevel, kuti kunoenderana sei neminwe yegoridhe, uye kuti Highleap Electronics inogadzira sei mabhodhi e edge-connector nemazvo.

1. Chii chinonzi edge connector bevelling?

Kukwesha kubatanidza makona (kunonziwo chamfering kana contour bevelling) inzira yekugadzira makona inokwesha chamfer yakakombama pamucheto wePCB panenge paine makona egoridhe neminwe, zvichiita kuti mucheto webhodhi upinde zvakanaka mu socket ine makadhi akafanana. Panzvimbo pe mativi matete, akapfava anobata ma connectors echitubu e socket, bevel inogadzira lead-in yakatsetseka inotungamira bhodhi.

Inoitwa pamabhodhi akagadzirirwa kubatanidza zvakananga mu connector ne edge modules dzavo - memory modules, expansion cards, uye akawanda backplane uye add-in boards. Bevel inochekwa mushure mekuputirwa kwegoridhe-minwe, ichiumba edge chaiyo inoenderana ne socket. Nekuti yakabatana ne gold contacts, bevelling chikamu chemaitiro akakura egoridhe-minwe pane danho rega rega, uye kunzwisisa hwaro hwema PCB egoridhe-minwe kunoita kuti chinangwa chayo chijeke.

2. Sei kucheneswa kwesimbi kuchidikanwa pakubatanidza kwemakadhi?

Kuchekerera kunodiwa nekuti mupendero webhodhi rechikwere unokwenya nekumanikidza matinji echitubu esoketi panguva yekuiswa, zvichikonzera matinji akakuvara, kukwenya kwegoridhe kwakakwenya, uye kubatana kusina kuvimbika - chamfer inopa lead-in yakatsetseka inodzivirira bhodhi nesoketi. Matinji emakadhi-edge anobata bhodhi nematinji akatsvuka pasi pekumanikidzwa, uye kumanikidza mupendero wakapfava pakati pawo ndiko kunokonzera kusakara uye kubatana kunoitika panguva yekuiswa kakawanda.

Bevel inogadzirisa matambudziko akati wandei panguva imwe chete: inoita kuti simba rekuisa rive nyore, inodzivirira mucheto wepamberi kuti usabvise goridhe (kuchengetedza conductivity yavo uye hupenyu hwavo), uye inobatsira kurongedza bhodhi mu socket. Kune zvigadzirwa zvinoiswa uye zvabviswa kakawanda, izvi zvinokanganisa zvakananga kugara kwenguva refu kwe connector uye kuvimbika kwechiratidzo. Ndiyo imwe yenzira dzekupedzisa dziri nyore kufuratira mukugadzirwa asi dzinoonekwa pachena mumunda kana dzisipo, ndosaka dzichifanira kutarisirwa zvakafanana netekinoroji yegoridhe.

3. Ndeipi kona ye bevel inoshandiswa (20°, 30°, 45°)?

Mabhevel emucheto anowanzo temwa pamakona akadai se20°, 30°, kana 45°, nekona chaiyo uye kudzika kwakasarudzwa kuti zvienderane nezvinodiwa neconnector uye ukobvu hwebhodhi. Hapana kona imwe chete yepasi rose — zvinoenderana nesoketi iyo bhodhi rinosangana nayo, saka datasheet yeconnector kana standard ndiyo inosarudza zvinodiwa:

Kona inoyerwa kubva pamusoro pebhodhi, uye pamwe nekudzika kwebevel inofanira kusiya matinji egoridhe akavhurika zvakanaka uku ichienderana ne lead-in yesocket. Nekuti chinodiwa chinobva kuconnector, tsika yakachengeteka ndeyekutora kona nekudzika kubva pa standard yeconnector pane kufungidzira, uye kuzvitaura zvakajeka kumugadziri. Bevel isiriyo inogona kuita kuti bhodhi riome kuisa kana kuratidza zvishoma (kana zvakawandisa) zvecontact.

4. Minwe inopenya negoridhe: mashandiro azvinoita pamwe chete

Chigunwe chinochekwa mushure mekunge zvigunwe zvaiswa jira, saka chinoumba mucheto wepamberi wezvigunwe zvatopedzwa. Pamwe chete zvinopa kubatana kwakavimbika, kunodzokororwa:

• Zvigunwe zvegoridhe dzakaputirwa negoridhe rakasimba pamusoro penickel kuti dzisaparare uye dzisabatane zvakanyanya, sezvo dzakagadzirirwa kuiswa nekubviswa kakawanda — pakati pe chigunwe chegoridhe patani.
• The bevel inoumba mupendero weminwe iyoyo kuitira kuti kuiswa kwacho kuve kwakatsetseka uye kuti matinji asakanganiswe, zvichipedzisa chinongedzo.

Kubatana uku ndiko kunoita kuti kugadzira ma "edge-connector" kuve nehunyanzvi hwakasiyana: goridhe rinofanira kugara kwenguva refu, ma "contacts" akaiswa zvakanaka, uye "bevel" rinofanira kuchekwa nemazvo zvichienderana ne "connector spec". Mugadziri ane mukurumbira we "gold-fingers" anoita zvese izvi senzira imwe chete yakabatana pane kutora "bevel" senzira yekufunga nezveramangwana.

5. Maitiro ekutsanangura mucheto webevel nemazvo

Kuti utsanangure kuchekwa kwemucheto nemazvo, taura kona yebhevel uye kudzika kubva pachiyero chekubatanidza, taura kuti ndeapi mucheto uye matinji akachekwa, uye simbisa kuti jira regoridhe-minwe rakachekwa uye ukobvu hwebhodhi kuitira kuti bevel ienderane nesoketi. Tsanangudzo yakajeka inodzivirira bhodhi risingapindi zvakanaka kana kuburitsa matinji zvisiri izvo. Isa pane zvinyorwa zvekugadzira:

• Kona yebhevel uye kudzika zvakatorwa kubva pane zvakataurwa ne connector, kwete kufungidzira.
• Mupendero upi uye kusvika papi bevel inomhanya, uye iyo inobatana nayo inovhara.
• Kuputira neminwe yegoridhe ruzivo, sezvo bevel nekubatana kwegoridhe kwakaoma zviri system imwe chete — ona tekinoroji yeminwe yegoridhe.
• Bhodhi gobvu, iyo pamwe chete nekona zvinosarudza geometry yemucheto wapera.

Kuisa izvi pamberi kunoita kuti mugadziri acheke bevel zvakanaka kekutanga. Sezvineiwo nedanho ripi zvaro rekupedzisa, iyi ndiyo mhando chaiyo yechinhu chinosimbiswa neongororo yekugadzira isati yagadzirwa bhodhi risati ragadzirwa, saka mupendero unoenderana nechinobatanidza charinofanira kubatana nacho.

6. Magadzirirwo anoitwa mabhodhi eHighleap anobatana nemucheto

Highleap inogadzira mabhodhi ekubatanidza ane makadhi ane goridhe rakasimba uye mabhevel emucheto akachekwa nemazvo anoenderana nezvinodiwa neconnector yako, senzira imwe chete yekupedzisa yakabatana. Zvigunwe zvegoridhe zvakaputirwa kuti zvigare kwenguva refu uye kuti zvisabatane zvakanyanya, uye bevel yacho inogadzirwa nekona yakatarwa uye kudzika kwayo kuitira kuti bhodhi ripinde zvakanaka uye mabhevel acho adzivirirwe pamusoro pekusangana kakawanda.

Nekuti minwe yebevel negoridhe inofanira kushanda pamwe chete nesoketi yakasarudzwa, kuwana plating, contact geometry, uye bevel right zvinoonekwa sehunyanzvi hwakanyanya mukugadzirwa kwePCB , uye bhodhi rakazadzwa nevanhu rinotsigirwa kuburikidza nekubatanidza. Ongororo yekugadzira inosimbisa kuti bevel angle, plating, uye ukobvu hwebhodhi zvinoenderana neconnector yako isati yagadzirwa. Paunokumbira mutengo, ipa connector kana standard iyo bhodhi inoenderana nayo, bevel angle uye kudzika, zvinodiwa neminwe yegoridhe, uye ukobvu hwebhodhi kuitira kuti mupendero ugadziriswe nemazvo.

7. Mibvunzo Inowanzo bvunzwa pamusoro pekubatanidza mucheto

Chinangwa chekubatanidza PCB edge connector ndechei?

Bevel inoita kuti bhodhi ripinde zvakanaka uye rakatetepa kuitira kuti bhodhi ripinde mu soketi ine mativi emakadhi pasina mativi emucheto akakweshwa kana kukuvadza ma spring contacts esocket, zvichidzivirira ma contacts ese ari maviri pamwe ne gold plating uye zvichivandudza kuvimbika kwe connection.

Ndeipi kona ye bevel yakajairika yekubatanidza mupendero?

Makona akajairika anosanganisira 20°, 30°, uye 45°, asi akakodzera anoiswa nezvinodiwa neconnector uye ukobvu hwebhodhi, kwete default yakajairika. Nguva dzose tora kona nekudzika kubva pa connector standard iyo bhodhi inoenderana nayo.

Kupenya kwemucheto kwakafanana here neminwe yegoridhe?

Kwete — minwe yegoridhe ndiyo inonamira madziro inotakura zviratidzo, ukuwo kupenya madziro ndiko kumucheto kwakaita semuchina unoibvumira kupinda zvakanaka. Izvikamu zviviri zvehurongwa hwekubatanidza makadhi, nekucheka minwe mushure mekunge minwe yanamira.
