The direction of the internal force of the core wire crimping portion itself in the state of being crimped to 0 is as shown in FIG. 1 (a), and this is schematically shown in FIG. 1 (b). .
This is because the left and right side surfaces 31 gradually linearly approach each other as they become deeper toward the bottom surface 32 having a semicircular cross section, and are smoothly connected to each other to form a deep groove 30 having a U-shaped cross section, and the crimper 3 is slightly concave. Anvil 4 with curved pressing end 41
Can be achieved by pressure molding the core wire crimping portion 11 having a U-shaped cross section using. As a result, the core wire portion 2 does not require as much compressive force as the Ω crimp.
The crimping force for 0 can be increased, and the electric wire is not easily scratched.
