Bad terminal crimping factors (4)

　　1.Mold damage

　　Due to abnormal operations (secondary crimping, etc.) and mold overload, the upper and lower crimping molds are scarred or cracked. Therefore, the inability to extrude the regular shape will cause big problems like burrs. Die abnormalities can be found by observing the crimping part.

　　Terminal deformation

　　The allowable range varies depending on the terminal, and is generally within ±5°. The twisted terminal will produce the same defect as the side bend.

　　2.Terminal deformation

　　Bend up：

　　The allowable range varies according to different terminals, generally within 3°. Terminals that are bent upward cannot be inserted into the shell. Even if they can be inserted, they will come off the nail and cause poor fitting on the other side 1.

　　Bend down：

　　The allowable angle varies somewhat depending on the terminal, and is generally within 3°. Terminals that are bent downward cannot be inserted into the shell, and even if the shell can be inserted, the nail will come off, and it will cause poor fitting at the other end.
