Vim muaj kev sib txuas sib txawv thiab cov qauv kev ua haujlwm,tub rog connectorsnrog cov khoom tsim nyog, kev tsim qauv tsim thiab kev siv yuav tsum tau xaiv. Cov tub rog sib txuas siv tau tuaj yeem tsim kom muaj kev ua haujlwm zoo dua qub los ntawm kev txuag cov nqi thiab txhim kho kev ua haujlwm ntawm lub tshuab. Ntxiv rau kev txheeb xyuas txiv neej thiab poj niam, cov tub rog muaj ntau yam haujlwm, suav nrog cov qauv ntawm lub cev, qhov loj me, kev tiv thaiv kev tiv thaiv, rwb thaiv tsev ntawm cov pins, dej tsis kam, siab sealing, siab ua haujlwm siab, kev pab lub neej ntev thiab kev sib txuas yooj yim thiab kev sib txuas.
Tsis tas li ntawd, qee qhov kev sib txuas yog "keyed", uas txhais tau hais tias qee qhov khoom siv ntawm cov khoom sib txuas yuav tiv thaiv kev sib txuas, thiab tshwj tsis yog siv cov khoom sib txuas kom raug, nws yuav ua rau kev sib txuas tsis raug lossis kev puas tsuaj. Qee cov tub rog sib txuas yog tsim los nrog lub kaw lus, xws li bayonet vaj tse, uas tuaj yeem tiv thaiv kev tsis sib haum xeeb lossis kev sib khi tsis zoo, qhov no suav nrog kev tiv thaiv dej thiab plua plav thiab kev tiv thaiv hauv thaj chaw muaj kev cuam tshuam loj.
Cov khoom sib txuas feem ntau yog tsim los ua kom tau raws li qee cov qauv kev lag luam, suav nrog cov qauv tsim los ntawm International Electrotechnical Commission (IEC), uas tsim cov qauv loj ntawm cov khoom sib txuas. Vim muaj coob tus connectors tsim, tshwj xeeb connector tsim yam tseem ceeb heev. Interoperability ntawm connectors yog ib qho tseem ceeb vim hais tias muaj ntau manufacturers tsim cov khoom uas siv tib connector style, thiab cov qauv tsim ntawm ib tug tshwj xeeb connector yuav cuam tshuam rau qhov haum rau daim ntawv thov.
