1.Exposed core

　　It betsjut dat de steat dêr't ien of mear kearn triedden wurde bleatsteld út de dirigint grip hjit bleatsteld kearn triedden.

　　Allinne de bleatsteld kearn tried sil feroarsaakje de tried te wurden tinner. Dêrneist, as de kearn wire kompresje oanstriid fan de crimping diel is los, it ferset sil tanimme, net te hawwen oer de tensile sterkte wurdt ferswakke. It is makliker te finen as it is fanselssprekkend, mar yn de measte gefallen Bottom kin it oerflak fan de gripende diel crush of brekke de kearn tried. De steat fan de nije kearn tried beskreaun yn de folgjende notysje is lestich te finen. sil feroarsaakje oermjittich kearn wire bleatstelling, minne fitting, spiker fuortheljen, minne terminal ynstallaasje, ensfh It is tige wierskynlik. heulendal. It sil tanimme de wjerstân fan de crimping diel en ferswakke de treksterkte. ien (of mear as ien) fan 'e bleatsteld kearn tried is yn in lange steat, dat kin foarmje in koartsluting mei oare circuits, min fitting en losse nagels. Wachtsje min.

　　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.
