- a metal mold was prepared by cutting a plurality of grooves on a metal member to form a convex portion having a predetermined shape. Using this mold, a metal plate made of a copper alloy whose surface was plated with tin was pressed, and further bent to produce a terminal fitting. The thickness dimension of the metal plate material was 0.25 mm.

Thereafter, the terminal fitting and the electric wire were each held with a jig, and a tensile test was performed. The pulling speed was 100 mm / sec. The stress when the electric wire was detached from the wire barrel of the terminal fitting was defined as the value of the fixing force. Ten samples were tested and the average values are listed in Table 1.
- the first hole edge intersects with the extending direction of the core wire at an angle of 85 ° or more and 95 ° or less.
- the angle formed between the first hole edge and the extending direction of the core wire is less than 85 °.
- the angle formed with the direction in which the core wire extends exceeds 95 °. For this reason, when the force along the extending direction of the electric wire is applied to the core wire, it is considered that the movement of the core wire cannot be sufficiently held depending on the edge formed in the first hole edge. Then, the core wire moves in a direction away from the surface of the wire barrel, and as a result, a portion that does not contribute to electrical connection with the wire barrel is generated on the new surface of the core wire. Thereby, it is considered that the electrical resistance between the electric wire and the terminal fitting could not be sufficiently reduced.
- the fixing force between the electric wire and the terminal fitting in Comparative Examples 1-1 to 1-4 was 55 N or less.

An electric wire with a terminal fitting was produced.
- Example 2-1 For Examples 2-1 to 2-3 and Comparative Example 2-1, the fixing force was measured in the same manner as in Example 1, and the electrical resistance was measured. The results are summarized in Table 2.
- the recesses adjacent to each other in the extending direction of the electric wire The first hole edge is arranged so as to overlap in the extending direction of the electric wire (see FIG. 7).
- region where the edge formed in the 1st hole edge of a recessed part bites into a core wire necessarily exists about the extension direction of an electric wire.
- the electrical resistance between the core wire and the terminal fitting was 1.5 m ⁇ , whereas with the terminal fitting according to Examples 2-1 to 2-3.
- the electric resistance between the core wire and the terminal fitting in the electric wire was 0.5 m ⁇ , which was reduced by about 67% compared to Comparative Example 2-1.
- Examples 3-1 to 3-3 and Comparative Examples 3-1 and 3-2> The angle formed by the first hole edge with respect to the direction in which the electric wire extends is 90 °, and the first inclined surface and the surface of the wire barrel on the side where the core wire is disposed and the portion where no recess is formed
- An electric wire with a terminal fitting was produced in the same manner as in Example 1 except that the angle formed by (hereinafter also referred to as the angle formed by the first inclined surface) was set to the values described in Table 3.
- the angle formed by the first inclined surface is less than 90 °, the angle formed by the first inclined surface becomes an overhang, so that the terminal fitting cannot be formed by press working.
- the concave portion is formed by pressing the convex portion formed in the mold against the metal plate material.
- the angle formed by the first inclined surface is a right angle or an obtuse angle in order to easily release the convex portion of the mold after pressing.
- the angle formed by the first inclined surface is 90 ° or more and 110 ° or less, and the right angle or the obtuse angle is relatively small.
- the edge formed in the 1st hole edge of a recessed part is a comparatively sharp thing.
- the edge formed at the edge of the first hole bites into the core wire, so that the oxide film formed on the core wire is surely peeled off, and the new surface of the core wire and the terminal fitting are in contact with each other. Thereby, it is thought that the electrical resistance between a core wire and a terminal metal fitting was reduced.
- Examples 4-1 to 4-4 and Comparative Examples 4-1 and 4-2> The angle formed by the first hole edge with respect to the direction in which the electric wire extends is 90 °, and the second inclined surface and the surface of the wire barrel on the side where the core wire is disposed and the portion where no recess is formed
- An electric wire with a terminal fitting was produced in the same manner as in Example 1 except that the angle formed by (hereinafter also referred to as the angle formed by the second inclined surface) was set to the values described in Table 4.

- Examples 4-1 to 4-4 in which the angle formed by the second inclined surface is 115 ° to 140 ° the electrical resistance between the core wire and the terminal fitting is 0.7 m ⁇ or less. It was. Thus, by setting the angle formed by the second inclined surface to 115 ° or more and 140 ° or less, the electrical resistance between the core wire and the terminal fitting could be reduced by about 50%. In Examples 4-1 to 4-3, since the electrical resistance between the core wire and the terminal fitting is 0.5 m ⁇ , the angle formed by the second inclined surface is preferably 115 ° to 130 °.
- the wire barrel is crimped so as to wind from the outside of the core wire. For this reason, when the wire barrel is crimped so that the wire barrel is wound around the core wire, the recess formed in the inner peripheral surface of the wire barrel is deformed so that the opening area of the hole edge portion is reduced. At this time, if the angle formed by the second inclined surface is excessively small, there is a concern that the opening area of the hole edge portion of the recess becomes excessively small and may be closed in some cases. Then, it is considered that the second hole edge of the concave portion cannot be brought into sliding contact with the core wire, and it becomes difficult to expose the new surface of the core wire. For the reasons as described above, in Comparative Example 4-1, it is considered that the electrical resistance between the core wire and the terminal metal fitting is relatively large at 1.4 m ⁇ .
- Example 1 except that the angle formed by the first hole edge with respect to the extending direction of the electric wire is 90 °, and the first pitch interval of the plurality of recesses in the extending direction of the core wire is set to the value described in Table 5. In the same manner, an electric wire with terminal fittings was produced.

- the plurality of recesses are arranged side by side with a relatively small first pitch interval of 0.3 mm or more and 0.8 mm or less in the extending direction of the electric wire. This increases the number of recesses per unit area. Then, the edge area formed at the hole edge of the recess per unit area increases. Thereby, the area
- the electrical resistance between the core wire and the terminal metal fitting was 1.2 m ⁇ , whereas in Examples 5-1 to 5-4, there was a gap between the core wire and the terminal metal fitting.
- the electrical resistance was 0.8 m ⁇ .
- the first pitch interval is preferably 0.3 mm or more and 0.5 mm or less.
- Examples 6-1 to 6-4 and Comparative Example 6-2> The angle formed by the first hole edge with respect to the extending direction of the first hole edge is set to 90 °, and the first pitch interval of the plurality of recesses in the extending direction of the core wire is set to a value described in Table 6. Produced the electric wire with a terminal metal fitting similarly to Example 1.
- FIG. 1 An example of Example 6-1 to 6-4 and Comparative Example 6-2> The angle formed by the first hole edge with respect to the extending direction of the first hole edge is set to 90 °, and the first pitch interval of the plurality of recesses in the extending direction of the core wire is set to a value described in Table 6.
- the plurality of recesses are arranged side by side with a relatively small first pitch interval of 0.3 mm or more and 0.8 mm or less in the wire extending direction. This increases the number of recesses per unit area. Then, the edge area formed at the hole edge of the recess per unit area increases. Thereby, the area
- the electrical resistance between the core wire and the terminal metal fitting was 1.2 m ⁇
- the electrical resistance between the core wire and the terminal metal fitting was between.
- the electric resistance was 0.7 m ⁇ .
- the second pitch interval is preferably 0.3 mm or more and 0.5 mm or less.
- the length dimension of the first hole edge 19 is set to 0.38 mm.
- the interval L1 between the recesses 18 adjacent to each other in the extending direction of the first hole edge 19 is adjacent to the extending direction of the core wire 13 (the direction indicated by the arrow A in FIG. 11). It is set to be narrower than the interval L2 between the matching recesses 18.
- the interval L1 is set to 0.12 mm
- the interval L2 is set to 0.19 mm.
- first region 40 located between the adjacent recesses 18 in the extending direction of the first hole edge 19 extends in the extending direction of the second hole edge 20 (the direction indicated by the arrow C in FIG. 11). As described above, the extending direction of the second hole edge 20 forms an angle of 30 ° with respect to the extending direction of the core wire 13.
- the second region 41 located between the adjacent recesses 18 in the extending direction of the core wire 13 is formed to extend in the extending direction of the first hole edge 19 (direction orthogonal to the extending direction of the core wire 13).
- the wire barrel 16 When the wire barrel 16 is pressure-bonded to the core wire 13, the first region 40 and the second region 41 located between the plurality of adjacent recesses 18 in the wire barrel 16 are pressed against the outer peripheral surface of the core wire 13. Then, the oxide film formed on the outer peripheral surface of the core wire 13 is destroyed, and the new surface of the core wire 13 is exposed. When the new surface comes into contact with the wire barrel 16, the core wire 13 and the wire barrel 16 are electrically connected.
- the interval L1 between the recesses 18 adjacent to each other in the extending direction of the first hole edge 19 is set to be narrower than the interval L2 between the recesses 18 adjacent to each other in the extending direction of the core wire 13. Therefore, the first region 40 located between the adjacent recesses 18 in the extending direction of the first hole edge 19 is wider than the second region 41 positioned between the adjacent recesses 18 in the extending direction of the core wire 13. It is formed narrowly.
- the first region 40 is formed relatively narrow, it is easy to bite into the core wire 13. As a result, the first region bites into the outer peripheral surface of the core wire 13, whereby the electrical resistance between the core wire 13 and the female terminal fitting 12 can be reduced.
- the first region 40 extends at an angle of 30 ° with respect to the extending direction of the core wire 13. For this reason, the first region 40 bites into the core wire 13 in a posture inclined with respect to the extending direction of the core wire 13. Therefore, as compared with the case where the first region 40 is formed orthogonal to the extending direction of the core wire 13, the core wire 13 is prevented from being broken by the first region 40 biting into the core wire 13. Thereby, it can suppress that the retention strength (adhesion force) between the electric wire 11 and the female terminal metal fitting 12 falls.
- the second region 40 extending perpendicularly to the extending direction of the core wire 13 also bites into the outer peripheral surface of the core wire 13 when the wire barrel 16 is crimped to the core wire 13. However, since the second region is formed relatively wide, the core wire 13 is prevented from being broken.
- the present invention is not limited to the embodiments described with reference to the above description and drawings.
- the following embodiments are also included in the technical scope of the present invention.
- the first pitch P1 in the extending direction of the core wire 13 of the plurality of recesses 18 formed in the wire barrel 16 is 0.4 mm, and in the extending direction of the core wire 13
- the second pitch interval P2 in the direction orthogonal to each other is 0.5 mm.
- the present invention is not limited to this, and both pitch intervals can be arbitrarily set as necessary. Further, both pitch intervals may be different from each other or may be the same value.
- the length of the 1st hole edge 19 which comprises the hole edge of the recessed part 18 is set to 0.25 mm, and the length of the 1st hole edge 19 which concerns on Embodiment 2 is set.
- the thickness was set to 0.38 mm, the length is not limited to this, and the length of the first hole edge 19 constituting the hole edge of the recess 18 can be arbitrarily set as necessary.
- an aluminum electric wire is used, but even when a copper electric wire is used, the adhesion force between the electric wire and the terminal metal fitting is not as great as that of the aluminum electric wire due to the adhesive force, etc. Compared to the prior art, there is no drawback caused by the electrical resistance between the electric wire and the terminal fitting. For this reason, this invention can also be used for copper electric wires, and this invention can also be used for the terminal metal fitting applicable to both a copper electric wire and an aluminum electric wire.
