本考案は電線に導電端子を圧着接続するために
用いられる端子圧着用の歯型構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a terminal crimping tooth structure used for crimping and connecting a conductive terminal to an electric wire.

Conventionally, in order to connect a crimp terminal to an electric wire, a terminal crimp tooth mold including an upper tooth mold 1 and a lower tooth mold 2 is used, as shown in FIG. 4, for example. The lower tooth mold 2 is formed into a male shape. An upper tooth mold 1 formed into a female mold is located above the lower tooth mold 2. During the connection work, a U-shaped crimp portion 3 of the conductive terminal is positioned between the upper tooth mold 1 and the lower tooth mold 2.
Further, a plurality of electric wires 4 are guided inside the crimp portion 3.

円弧に沿つて形成されている。 A gently curved shallow recess 5 is formed on the upper surface of the lower tooth mold 2. The bottom part 6 of the crimp part 3 is located on the inner surface of the recessed part 5. The inner surface of the upper tooth mold 1 has two arched portions 8 that are plane symmetrical with respect to a vertical imaginary plane including the central portion 7 thereof. These arched portions 8 are formed along one arc of radius R.

The tip 9 of the crimp part 3 is the arched part 8 of the upper tooth mold 1.
along the lines, they are pressed and bent toward each other toward the central portion 7. In this way, the electric wire 4 is finally rounded and crimped to surround it.

However, when the crimping part 3 is positioned in an inclined state, the position of its tip 9 becomes unbalanced. Possible causes of this include, for example, the conductive terminal itself being deformed, or the center of the conductive terminal and the center of the tooth pattern not matching. Therefore, in this case, when crimping, one tip 9 of the crimping part 3 will first hit the inner wall of the arched part 8 of the upper mold 1, so as shown in FIG. The tip 9 of the crimping part 3 is bent first. Finally, as shown in FIG. 6, the crimp portion 3 divides the plurality of electric wires 4 and causes the crimp terminal to be twisted. In particular, since the wire 4 does not enter the crimp part 3 evenly, the crimp becomes unstable, creating a gap between the wire 4 and the inside of the crimp part 3, and as a result, the crimp strength is insufficient, causing the wire to become unstable. 4
There is also a risk that it may come off.

According to the present invention, in the tooth type structure in which the crimp part of the conductive terminal and the electric wire arranged inside the crimp part are positioned between the upper tooth mold and the lower tooth mold to perform the crimp connection, The inside of the tooth mold has two arched portions arranged adjacent to each other and symmetrical in plane, and each of the curved lines forming the arched portions extends from a point on an imaginary straight line that crosses the curved line to the other arch. It has a first circular arc portion extending toward the shape part side and a second circular arc portion extending toward the opposite side, and the first circular arc portion and the second circular arc portion substantially point at mutually different points on the imaginary straight line. A tooth-shaped structure for terminal crimping is obtained, characterized in that the center of curvature is set at a center of curvature, and the radius of curvature of the first circular arc portion is larger than the radius of curvature of the second circular arc portion.

1 and 2 show an embodiment of the present invention. Further, FIG. 3 shows the crimp portion after the crimp connection has been completed. The tooth mold for terminal crimping includes an upper tooth mold 11 formed in a female mold and a lower tooth mold 2 formed in a male mold. A U-shaped crimp portion 3 of a conductive terminal is positioned between the upper tooth mold 11 and the lower tooth mold 2. Furthermore, a plurality of electric wires 4 are guided inside the crimp portion 3. A gently curved shallow recess 5 is formed on the upper surface of the lower tooth mold 2, and the bottom 6 of the crimp part 3 is located in the recess 5.

分８を形成する。 The inner surface of the upper tooth mold 11 has two arched portions 8 adjacent to each other and symmetrical with respect to a vertical virtual plane P including the central portion 7 thereof. Each of the curves forming these arched portions 8 has an apex T P located symmetrically with respect to the plane P. And a vertical virtual straight line l including this vertex T P
The circular arcs 12 and 13 on the left and right sides of are formed with respective radii R 1 and R 2 that are substantially centered on the virtual straight line l. Moreover, arc 1 on the virtual plane P side
The radius R 1 of arc 2 is larger than the radius R 2 of arc 13 on the opposite side. The resulting respective arcs 12, 13 are smoothly connected to each other and form an arcuate portion 8 as a whole.

込み力を必要とする。 When crimping work, first arc 1 indicated by radius R 2
3, the tip portions 9, 9' of the crimp portion 3 move.
At this time, if the right and left tips 9, 9' of the crimp part 3 are in an unbalanced state, the tips 9, 9' of the crimp part 3 will be on one side at the boundary between the arcs 12, 13 due to the difference in the arcs 12, 13. The movement of the tip 9 of is restricted. The restriction continues until the other lagging tip 9' comes to the same position. The radius R 2 of the arc 13 is
It is made smaller than the radius R1 of the circular arc 12. Therefore, in order for one tip 9 to move from arc 13 to arc 12 at the boundary between each arc 12 and 13, a larger force is required than when moving in arc 13, that is, one tip 9 is required to move from arc 13 to arc 12. Requires a large force to encircle.

電線４を均等に取り囲んでまるめられる。 Therefore, in this state, the balance of forces in the rotational movement direction of the left and right tips 9, 9' of the crimping part 3 is disrupted, so the other tip 9' does not rotate until the left and right forces are balanced. do. Therefore, one tip 9 of the crimp portion 3 is temporarily restrained at the boundary between the arcs 12 and 13. Thereafter, as shown in FIG. 2, when the left and right tips 9, 9' of the crimp section 3 become even, the pressing and bending operation of one tip 9 is restarted. In this way, finally, the crimp portion 3 evenly surrounds and curls the plurality of electric wires 4.

とは言うまでもない。 Although the curve forming the arched portion 8 is obtained by a combination of two circular arcs 12 and 13 with different radii, the same effect can be obtained by combining three or more circular arcs with different radii. Needless to say, it plays.

As described above, according to the tooth-shaped structure for terminal crimping of the present invention, the final crimping is performed after the tip of the crimping part is evenly positioned during the crimping operation.
Twisting of crimp terminals can be prevented. Further, since the electric wire is evenly surrounded within the crimp portion, the strength of the crimp connection becomes uniform, and a stable crimp connection can be obtained.
