Maqaarka qaniinay (garaac qoto dheer)

　　Waxay loola jeedaa ifafaalaha in kirishbooyada qabsada qaybta qabsata dahaarka (caag). Waxaa jira dahaar gudaha qaybta qaboojinta kirishbooyada, taas oo aan fududeyn oo kaliya in la jebiyo, haddii cidhiidhigu aad u adag yahay, xiriirka ka dhexeeya siliga xudunta ah iyo terminalka waa la dhimi doonaa, taas oo keeneysa iska caabin xad dhaaf ah Kordhinta dhererka waxay keeni doontaa shilal waaweyn. sida kulaylka iyo gubashada. Marka maqaarku daboolan yahay, sida sawirka hoose ka muuqata, way fududahay in la helo marka dhammaan la xidho, laakiin sida ka muuqata sawirka midigta, qaybta qabata kaari waxay sidoo kale yeelan kartaa xaalad qaniinyo ah xaalado gaar ah. Xaaladdan oo kale, way adag tahay in la helo. Ogaysiis. Sidaa darteed, waxaa jirta sabab loo filayo in saamiga siliga xudunta ah iyo dahaarka la filayo inuu noqdo 1:1. caarada siliga xudunta u ah kama muuqato cidhifka kaarida. ka soocay xajinta dahaadhka. Sababo la xiriira xoogag dibadeed, Waa sababta jabinta siliga cidhifka qabsashada.

Wire backward (light hitting)

　　It refers to the state where the position of the wire is deviated, and the tip of the core wire is not visible from the tip of the conductor grip.

　　Due to the reduction of the effective pressing area, not only the tensile.

　　Neck hanging refers to the phenomenon that the covering (peeling) is separated from the insulating grip. Due to external forces, It is the cause of wire breakage at the edge of the grip.
