Short Sheet Hlau Screws

Cov neeg feem ntau siv 0.8 txog 1.2 hli tuab steel daim hlau los ua cov khoom siv hauv tsev xws li tshuab ntxhua khaub ncaws thiab microwave ncu. Koj tuaj yeem kho lawv yooj yim nrog ST 3.5 × 8 mm luv daim ntawv hlau ntsia hlau. Lub 1.0 hli steel phaj nrog ib lub hau ntswj tuaj yeem tuav txog 2,500 N ntawm kev rub lub zog, uas yog ntau tshaj li 500 N kev ruaj ntseg yuav tsum tau rau cov khoom siv hauv tsev. Cov xov luv luv, ntawm qhov tod tes, yuav tsis nkag mus rau hauv lub casing thiab ua mob rau cov circuits sab hauv.

Cov neeg feem ntau siv cov ntawv hlau luv luv los txuas qhov rooj trims, dashboards, thiab lwm yam khoom yas rau cov ntawv hlau. Cov kev ntsuam xyuas tau pom tias qhov rub- tawm quab yuam ntawm ST 4.2 × 10 mm screws ntawm 2.0 mm yas phaj tuaj yeem ncav cuag 800 N, txawm tias lub tsheb vibration ib puag ncig tsuas yog xav tau lub zog tuav ntawm 200 N. Nws tsis mus dhau ntawm lub nraub qaum ntawm tus ncej vim nws luv (tsawg dua lossis sib npaug li 10 hli), yog li nws tsis tau txais txoj hauv kev.

Cov pa cua nrog cov phab ntsa nyias tsuas yog 0.6 txog 0.8 hli tuab thiab xav tau luv AB - hom ntawv hlau ntsia hlau nrog cov lus qhia taw qhia. Muab piv rau lub sij hawm installation ntawm 12mm screws thiab 20mm screws qhia tau hais tias tapping ib 12mm ntsia hlau tsuas yog siv 4 lem, uas txuag 35% ntawm lub sij hawm installation. Nws kuj tseem yuav tsis ua kom lub pob rau ntawm sab nraud ntawm cov pa cua, uas ua rau sab hauv ntawm cov pa cua du thiab txo cov suab nrov ntawm cov pa tawm.

EMI shielding npog ntawm lub xov tooj txawb chaw nres tsheb thiab router yog 0.3 hli tuab thiab xav tau luv micro screws uas yog 2.2 × 4 hli. Cov ntaub ntawv qhia tau hais tias cov ntsia hlau no tsuas yog ntsia tau nrog lub zog ntawm 0.3 N·m, uas nws tsuas tuaj yeem ntsia tau rau hauv qhov tob ntawm 2 hli, thiab nws yuav tsis kov lub rooj tsav xwm hauv qab no. Nws muaj qhov tawv tawv ntawm ntau dua HV 500 thiab tuaj yeem yooj yim tau los ntawm cov ntawv hlau galvanized los ntawm tus kheej -tapping.

Cov hlua txuas txuas ntxiv tuaj yeem tho rau sab hauv ntawm qhov hollow profiles lossis nyias -cov phab ntsa phab ntsa, ua rau kev ua haujlwm tsis zoo. Qhov luaj li cas ntawm compact screws tuaj yeem txwv rau feem ntau ob npaug ntawm phab ntsa thickness. Qhov no ua kom muaj kev nyab xeeb thiab kev cia siab rau, vim tias txoj hauv kev ntawm kev tawg tau raug tshem tawm thaum qhov kev sib koom ua ke tseem tuaj yeem tiv taus 1500 N ntawm kev tawm dag zog.

Thaum kho ib feem uas twb muaj ua ntej - xov lub qhov, compact screws yeej tsis txuas mus rau lub qhov hauv qab. Yog tias cov kab noj hniav ntsuas tsuas yog 12 hli hauv qhov tob, xaiv 10 hli luv fasteners tawm 2 hli tiv thaiv kev tshem tawm, tshem tawm cov kab nrib pleb ntawm ob qho kawg. Cov txheej txheem no boosts lub neej kev pab cuam ntawm lub kho kev sib koom tes los ntawm ntau tshaj 50%.

Hauv cov chaw kaw, cov hlua txuas ntev dua feem ntau tsis tuaj yeem tsav ncaj nraim vim muaj kev cuam tshuam los ntawm cov khoom nyob ib puag ncig. Compact screws ntsuas nyob rau hauv 25 hli nyob rau hauv ntev yog zoo tagnrho rau nruj sib dhos qhov sib txawv ntawm qhov chaw tsuas yog 30 hli. Qhov no tiv thaiv cov cuab yeej sib tsoo nrog cov khoom nyob ib sab thiab txhim kho thawj zaug - lub sijhawm sib dhos ua tiav ntau dua 25%.

Ua tsaug rau lawv qhov chaw sib tiv tauj tsawg, cov screws compact tsim tsawg triboelectric them thaum lub sij hawm tsim hluav taws xob. Kev ntsuas qhia tau hais tias ST 2.9 × 6 mm fasteners txhim kho tus nqi zoo li qub ntawm kwv yees li 200 V tom qab taug kev los ntawm lub tais ntim khoom yas. Conversely, 20 mm ntev screws tsim ib tug static voltage ntawm 500 V. Lub tom kawg muaj ib tug ntau dua nyiam nyiam plua plav hais los yog puas rhiab Cheebtsam.
