Description

[Brief explanation of the drawing]

The attached drawings, FIGS. 1 to 11, show preferred embodiments of the present invention. FIG. 1 is a perspective view that simply shows the correspondence between the crimp terminal and each tooth type, and FIG. 2 is a male crimp tooth type. Figure 3 is a plan view of the crimp terminal.
Fig. 4 is a right side view of the crimp terminal, Fig. 5 is a cross-sectional view of the insulation coating crimp section taken along the Y-Y line in Fig. 4, and Fig. 6 is a cross-sectional view taken along the Z-Z line in Fig. 4. 7 to 11 are diagrams sequentially showing the steps of crimping the insulating coating, and FIGS. 12 to 15 show the conventional example, and FIGS. 12
The figure shows the shape of a conventional insulation coating crimping part before crimping, Figure 13 is an explanatory diagram of the crimping process using a conventional crimping male tooth die, and Figures 14 and 15 are cross-sections of the insulation coating crimping part. In the figure, 9 is a male tooth type for core wire crimping, 10 is a male tooth type for insulation coating crimping, 11a, 11
b indicates a linear guide wall, 12a and 12b indicate curved guide walls, and 13a and 13b indicate inclined guide walls.

Claims (1)

[Claim for Utility Model Registration] For crimping and fixing the core wire 7 of the electric wire 6 to the core wire crimping part 4 of the crimp terminal 1, or crimping and fixing the insulation coating part 8 of the electric wire 6 to the insulation coating crimping part 5 of the crimp terminal 1. In a crimp male tooth mold for a crimp terminal for crimping or fixing both of them; When this tooth mold moves downward toward each crimp part, the left and right crimp pieces forming the crimp part It has symmetrical inclined guide walls 13a and 13b which are tilted upward as they go left and right, starting from the virtual center line N of this tooth shape, respectively, for positioning at the center of the tooth shape. Each inclined guide wall 13
a, 13b, and by drawing arcs in the left and right directions, the upper portions of the left and right crimp pieces constituting the crimp portion are mutually connected as the tooth shape further moves downward. It has symmetrical curved guide walls 12a and 12b for moving the left and right crimp pieces inward and deforming them so that they come into close contact with each other, and for curving the upper ends of the left and right crimp pieces outward so as to separate them from each other,
and the left and right curved guide walls 12a, 12b.
The crimping portions are continuous with each other at the end point of the tooth shape, and extend downward with a slight inclination, so that as the tooth shape further moves downward, the crimp portions forming the above-mentioned crimp portions are curved in the left-right direction. A crimp male tooth type for a crimp terminal, characterized in that it has left and right symmetrical linear guide walls 11a and 11b for further curving the upper ends of the left and right crimp pieces.
