- the required lengths of the terminal body 3 and the crimping portion 5 are defined, and the upper surface of the terminal body 3 needs to have a specified length in consideration of connectivity. That is, only the terminal body 3 cannot be shortened. Therefore, when the transition portion 4 is gently raised, there is a problem that the total length of the terminal becomes long.
- the transition portion 4 can gently rise from the side portion 8a to the side portion 8b. That is, there is no sudden rise from the end portion of the sealing portion 22 toward the upper portion of the terminal body 3 (for example, a substantially vertical rise with respect to the bottom portion 6a). For this reason, the distance between the terminal body 3 and the sealing portion 22 is increased, and the force applied to the terminal body 3 causes the base portion of the transition portion 4 (near the boundary portion with the sealing portion 22) or the upper portion of the terminal body 3 to be close. It is possible to suppress the occurrence of stress concentration.
- the formation of the surface 14 becomes easier by providing the notch 12. Further, the rise of the surface 14 does not become abrupt.
- the shape of the notch 12 is not limited to that shown in FIG. That is, as shown in FIG. 6, the notch 12 is not formed in the side portion 8b from the lower side of the side portion 8b until reaching the upper portion of the terminal body, but another form may be adopted.

- the notch 12 may be continuously formed not only on the side portion 8 b but also on the upper portion of the terminal body 3. That is, the notch 12 may be formed continuously from the side surface of the terminal body 3 to the upper surface of the terminal body 3, and a part of the upper portion of the terminal body 3 may be cut away. Thus, even if the notch 12 is formed in the side portion and part of the upper portion while ensuring the length of the terminal body 3, the same effect can be obtained.
- the form of the notch 12 may be any. However, it is desirable that the shape of the notch 12 be formed with a curve that is as gentle as possible.
- the shape of the surface 14 is not limited to that shown in FIG.
- the surface 14 may be formed to be curved downward.
- a sealing mold matched to the curved shape may be used. By setting it as such a curved shape, the intensity
- the shape like the surface 14 may be formed not only on the upper surface of the transition portion 4, but also on the lower surface. That is, you may form so that the bottom part 6a may bulge below as it goes to the terminal main body 3 from the sealing part 22.
- the bottom portion 6a to the bottom portion 6b may not be formed straight, but may be formed so that the surface 14 and the bottom portion 6a spread vertically from the sealing portion 22 as a starting point.
- FIG. 11 is a partial plan view of the transition section 4.
- the sealing shape of the sealing portion 22 is different. That is, in the above-described example, as shown in FIG. 3, the sealing portion 22 is formed over the entire width direction (left-right direction in the drawing) of the terminal 1, and the length of the sealing portion 22 (up-down direction in the drawing). The length is formed in a substantially rectangular shape regardless of the width position.
- the form of the sealing portion 22 changes depending on the width position.
- the vicinity of the substantially central portion in the width direction of the sealing portion 22 protrudes toward the transition portion 4 side with respect to both end portions in the width direction of the sealing portion 22. It becomes a form. That is, the sealing portion 22 has a tapered shape so that the sealing length gradually decreases from the vicinity of the center portion.
- the taper shape may be a straight line or a curved line.
- the surface 14 mentioned above can be formed more easily by shortening the sealing length near the both ends of the width direction of the sealing part 22. Further, in the vicinity of both end portions of the sealing portion 22, the form in which the surface 14 gradually moves away from the bottom portion 6 a toward the terminal body 3 from the sealing portion 22 side can be made gentler.
- the substantially central portion of the sealing portion 22 has a length that can be reliably sealed, the water tightness of the crimping portion 5 can be ensured.
- FIG. 12 is a perspective view of the terminal 1f
- FIG. 13 (a) is a longitudinal sectional view of the terminal 1f.
- the terminal 1f has substantially the same configuration as that of the terminal 1 except that the surface 14 is not formed, and the process for forming the wire harness is also the same.
- a notch 12 is provided in a part of the side surface of the terminal body 3.
- the transition part 4 is formed so as to be connected to the notch 12 from the end part (transition part 4 side) of the sealing part 22. That is, the bottom part of the transition part 4 is continuous with the bottom part of the terminal body 3, and at least a part of the side part rising from the sealing part 22 of the transition part 4 is continuous with the side part of the terminal body 3.
- the sealing part 22 like FIG. 3 or FIG.
- FIG. 13 (b) is a cross-sectional view taken along the line DD of FIG. 13 (a)
- FIG. 13 (c) is a cross-sectional view taken along the line EE of FIG. 13 (a).
- the bottom portion 6a of the transition portion 4 and the bottom portion 6b of the terminal body 3 are continuous.
- the side portion 8 a of the transition portion 4 gradually rises from the sealing portion 22 side and continues to the notch 12 formed in the side portion 8 b of the terminal body 3.
- the notch 12 As described above, by providing the notch 12, it is possible to make the sudden rise of the portion connected to the terminal main body 3 from the end of the sealing portion 22 (end on the transition portion 4 side). For this reason, the stress concentration generated at the boundary between the transition portion 4 and the terminal body 3 can be reduced by the force generated in the terminal body 3 when the terminal 1 is molded or used.
- the shape of the notch 12 is not limited to that shown in FIG. That is, as shown in FIG. 13, the notch 12 is not formed in the side portion 8b from the lower side of the side portion 8b until reaching the upper portion of the terminal body, but another form may be adopted.
- the notch 12 is not formed so as to reach the upper part of the terminal body 3, but a part of the side part 8 b is notched and the edge (transition) of the upper part of the terminal body 3 is formed. You may form so that it may connect with the upper edge part of the part 4 side. Further, as shown in FIG. 14B, even if the notch 12 is formed only in a part of the side portion 8b without connecting to the upper portion of the terminal body 3, the effect can be obtained.
- the notch 12 may be continuously formed not only on the side portion 8 b but also on the upper portion of the terminal body 3. That is, the notch 12 may be formed continuously from the side surface of the terminal body 3 to the upper surface of the terminal body 3, and a part of the upper portion of the terminal body 3 may be cut away. Thus, even if the notch 12 is formed in the side portion and part of the upper portion while ensuring the length of the terminal body 3, the same effect can be obtained.
- the form of the notch 12 may be any. However, it is desirable that the shape of the notch 12 be formed with a curve that is as gentle as possible.
- a plurality of wire harnesses according to the present invention can be bundled and used.
- a structure in which a plurality of wire harnesses are bundled in this way is referred to as a wire harness structure.
