1.Exposed core

　　Waxa ay la macno tahay in gobolka halka ama in ka badan oo fiilada xudunta ah ay ka soo baxaan xajinta kirishbooyada loo yaqaan fiilooyin core oo bannaan. Intaa waxaa dheer, haddii u janjeera silig xudunta u janjeera qaybta crimping waa dabacsan, iska caabin ah ayaa kordhin doona, ma aha in la xuso xoogga dhufto ah waa la wiiqi doonaa. Way fududahay in la helo marka ay caddahay, laakiin inta badan kiisaska Gunta, dusha sare ee qaybta xajinta ayaa laga yaabaa inay burburiso ama jebiso siliga xudunta u ah. Xaaladda siliga cusub ee xudunta u ah ee lagu tilmaamay qoraalka soo socda way adag tahay in la helo. Waxay sababi doontaa soo-gaadhista siliga xudunta u ah xad-dhaafka ah, ku habboonaanta liidata, ciddida ka saarista, rakibidda terminalka liidata, iwm. Waxay u badan tahay inay dhacdo. haba yaraatee. Waxay kordhin doontaa caabbinta qaybta curyaaminta waxayna daciifin doontaa xoogga xajinta. mid ka mid ah (ama in ka badan) oo ka mid ah siligga xudunta u ah ayaa ku jira xaalad dheer, taas oo laga yaabo inay sameeyaan wareeg gaaban oo leh wareegyo kale, ku haboonaansho liidata, iyo cidiyaha dabacsan. Sug xun

　　Only the exposed core wire will cause the wire to become thinner. In addition, if the core wire compression tendency of the crimping part is loose, the resistance will increase, not to mention the tensile strength will be weakened. It is easier to find when it is obvious, but in most cases Bottom, the surface of the gripping part may crush or break the core wire. The state of the new core wire described in the following note is difficult to find.

　　2.Excessive core wire exposure

　　Even if the covering position is correct, if the exposed size of the core wire is too long, it will cause excessive core wire exposure, poor fitting, nail removal, poor terminal installation, etc. It is very likely to occur.

　　3.No core wire exposed

　　This refers to the state where the thread opening is not exposed at all. It will increase the resistance of the crimping part and weaken the tensile strength.

　　3.Uneven cores (cores lead out)

　　It means that the wire opening of the wire is pressed when the core wire is not neat, and one (or more than one) of the exposed core wire is in a long state, which may form a short circuit with other circuits, poor fitting, and loose nails. Wait bad.
