It is manufactured by punching a thin plate of copper alloy or the like into a predetermined shape and then bending it. For example, as shown in Figure 8, it is a semicircular shape with a tab terminal inserted at one longitudinal end. An electrical contact portion 30 having elastic pieces 31, 31 is provided, and a covering crimping portion 20 having a substantially U-shaped cross section similar to the core wire crimping portion 10 having a substantially U-shaped cross section is provided on the other end side. .
Here, on the inner surface of the core wire crimping part 10, a plurality of serrations 11 extending in a direction perpendicular to the longitudinal direction are provided.
are formed at appropriate intervals.

次のように表される。 FIGS. 9 and 10 show a state in which the wire 40 is crimped and held on the wire crimp terminal. In this case, first, the insulation coating 41 is peeled off to expose the core wire 42 made up of multiple strands, and the end portion of the wire is removed.
Insert into the core wire crimping part 10 and the covering crimping part 20,
Next, by a crimping device (not shown), the core wire 42 is crimped by the core crimping part 10, and the insulation coating 41 is crimped by the sheath crimping part 20, so that the electric wire 40 is crimped and held. Note that the tip portion 42a of the core wire 42 is configured to protrude from one end edge 10a of the core wire crimping portion 10. Further, the compression ratio when crimping the core wire 42 is set to 100% or less. This compression ratio is expressed as follows.
圧縮率＝圧着内側断面積／圧着前素線計算断面積×
100％
ここで、芯線４２部分についてみると、第１１

100% Here, if we look at the core wire 42 part, the 11th
As shown in the figure, the tip end portion 42a that is compressed by the core wire crimping portion 10 and protrudes from the core wire crimping portion 10 expands in a ragged shape and comes into contact with the edge 10a of the core wire crimping portion 10, while the core wire 42a protrudes from the core wire crimping portion 10. Some of them are in the serration 11. In this case, the resistance force against the force that causes the core wire 42 and the core wire crimping portion 10 to separate from each other, that is, the crimping holding force (the force that maintains the crimping tensile strength) is
0, the reaction force of the force trying to pull out the core wire 42 biting into the serrations 11, and the force generated at the end edge 10a against the force trying to compress the tupular expansion of the tip portion 42a. The force is the sum of the reaction force and the reaction force.

60277号公報参照）。 In addition, as another wire crimp terminal, for example, the 12th
As shown in the figure, it has been proposed that a plurality of slits 12 are provided in the core wire crimping section 10 instead of the serrations 11, and a portion of the core wire 42 is bitten into the slits 12 (in 1987). −

恐れがあつた。(Problems to be Solved by the Invention) However, the edge portions of the serrations 11 are likely to be damaged by the edge portions 42 of the slits 12, causing core wire breakage, etc., and there is a fear that the crimp holding force may be reduced.

る。[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides an electric wire crimper having a core wire crimping portion for crimping and holding the core wire of an electric wire consisting of a large number of strands. At the terminal,
The core wire tip end side edge of the core wire crimping portion is formed into a concave shape.
It is characterized by being formed in a convex or uneven shape.

ある。 In this invention, "formed in a concave, convex, or uneven shape" means formed in a concave, convex, or uneven shape from the viewpoint of increasing the contact length between the edge of the core wire crimping part and the core wire. However, the concave shape is not limited to a simple arcuate concave shape, and the concave and convex shape includes not only a gently wavy shape but also a sawtooth shape.

ぼめる力に対する反力が増加する。(Function) When the core wire is crimped with the core wire crimping part, the tip of the core wire spreads out in a loose shape, and the tip comes into contact with the edge of the core wire crimping part, but this edge has a concave, convex, or uneven shape. Since the terminal is shaped like a straight line, the contact length with the core wire is larger than that of a conventional wire crimp terminal that is formed in a straight line, and the reaction force against the force that compresses the tip increases accordingly.

以下、この発明の一実施例を図面を参照して詳
細に説明する。(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

保持力を向上させた点である。 In other words, the wire crimp terminal shown here is also manufactured by punching a thin plate of copper, copper alloy, etc. into a predetermined shape, and then bending it, and it has a semicircular shape into which a tab terminal is inserted at one longitudinal end. An electrical contact portion 30 having elastic pieces 31, 31 having a shape of 32 is provided, and a covering crimping portion 20 having a substantially U-shaped cross section similar to the core wire crimping portion 10 having a substantially U-shaped cross section is provided on the other end side.
is provided. An important point in this invention is that the core wire tip end side edge 10b of the core wire crimping portion 10 and the core wire 4
The point is that the contact length with the wire 2 is increased to improve the crimp holding force of the wire 40.

加締め部１０や被覆加締め部２０等と同時に形成
される。 In this first embodiment, the end edge 10 on the side from which the tip portion 42a of the core wire 42 consisting of a large number of strands protrudes
By forming b so as to be concave (concave) in a substantially circular arc shape, the length of contact with the core wire 42 is increased. This edge 10b is formed at the same time as the core wire crimping part 10, the covering crimping part 20, etc. when punching out the expansion plate of the wire crimp terminal (see FIG. 1).
このようにすると、芯線加締め部１０で芯線４

このためラツパ状に拡がつた芯線４２の先端部分
４２ａをつぼめようとする力に対する反力が増
す。 In this way, the core wire crimping part 10
2 is crimped, the contact length between the edge 10b and the tip portion 42a of the core wire 42 is larger than that of the conventional straight edge 10a (see FIG. 9).
For this reason, the reaction force against the force that tends to compress the distal end portion 42a of the core wire 42, which has spread out in a convoluted shape, increases.
また、端縁１０ｂはほぼ円弧状に凹んでいるた

４２との間の摩擦力の低下も防止される。 In addition, since the end edge 10b is concave in a substantially arc shape, some of the core wires 42 are pushed sideways when a force is applied to compress the tip portion 42a, and the straight end edge 10a The core wires 42 interfere with each other in a more complicated manner than in the case of , and this interference generates a new reaction force against the force that attempts to pull out the core wire 42 from the core wire crimping part 10 . Furthermore, since the core wires 42 interfere with each other in a complicated manner, changes in the relative positional relationship between the core wire crimping portion 10 and the core wire 42 are reduced, and the frictional force between the inner surface of the core wire crimping portion 10 and the core wire 42 is reduced. This also prevents a decrease in
この結果、セレーシヨン１１（第８図、第１１

うなおそれがなく、圧着保持力を向上させること
が出来る。 As a result, serration 11 (Fig. 8, 11
The crimp holding force of the electric wire 40 can be improved without providing the slit 12 (see FIG. 12) or the slit 12 (see FIG. 12). In other words, there is no fear that the core wire will break, and the crimp holding force can be improved.
第６図及び第７図はこの発明の第２実施例を示
すもので、端縁１０ｂを凹凸状に形成しており、
他の点については上記第１実施例と同じである。 6 and 7 show a second embodiment of the present invention, in which the edge 10b is formed in an uneven shape,
The other points are the same as the first embodiment.
このようにすると、端縁１０ｂと芯線４２との

の発明を適用出来ることは勿論である。 Note that the edge 10b may be formed in a convex shape. Further, the core wire crimping part 10 is formed to have a substantially U-shaped cross section, and the bundle of core wires 42 is divided into two by the crimping pieces 13, 13.
Although the case is shown in which the parts are divided and held by pressure (see FIG. 5), the invention is not limited to this. moreover,
The edge of the covering crimped portion 20 may also be formed into a concave, convex, or uneven shape. Furthermore, it goes without saying that the present invention can also be applied to a so-called wire crimping terminal of the type in which the core wires are crimped together, which does not include the covering crimping part 20 or the electrical contact part 30.
