WIRE HARNESS, METHOD OF CONNECTING TERMINAL AND COATED WIRE, AND MOLD

WIPO Patent Application WO/2015/064763

A1

The height (F) of a protruding portion (7) is less than the thickness of a crimping portion (5) before crimping. If the height (F) of the protruding portion (7) is greater than the thickness of the crimping portion (5), then a recess is prone to form in the inner surface of the crimping portion (5). In other words, because there is more metal flowing outwards, a recess corresponding to the metal flow is prone to form on the inner surface side. If such a recess does form, adhesion with a covered area (27) is likely to deteriorate. This is problematic because such a gap would be a path allowing the ingress of moisture. On the other hand, if the height (F) of the protruding portion (7) is less than the thickness of the crimping portion (5) before crimping, then when the crimping portion (5) is compressed during crimping, the amount of metal flowing towards the protruding portion (7) diminishes, making it possible to suppress the formation of a receding portion on the inner surface of the crimping portion (5).
