[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting method and a connecting device for a flat cable and a flat cable connecting terminal used for electric wiring of electric equipment, automobiles and the like.

[0002]

2. Description of the Related Art FIG.
As shown in FIG. 6, a plurality of flat conductors 1 made of strip-shaped conductors such as copper and aluminum arranged in parallel and having a thickness of 0.15 mm and a width of 1.5 mm to 3.0 mm are
Flat cables 3 having a structure in which they are collectively covered with a flat insulating coating 2 made of plastic such as polyethylene terephthalate have come to be used.

In such a flat cable 3, a crimp piece 6 and a holding piece 7 are arranged on both sides of the terminal plate portion 5 connected to the female terminal body 4 in the width direction, and the crimp pieces 6 and the holding pieces 7 are located at different positions in the longitudinal direction of the terminal plate portion 5. The flat cable connecting terminal 8 having a structure in which it is erected on the same side of the terminal plate portion 5 is used.
Then, the terminal connecting portions 9 are formed by connecting the flat conductors 1 at the respective positions. In this example,
The crimp pieces 6 are staggered in a staggered manner, and the holding pieces 7 are stood facing each other.

Before the flat cable connecting terminal 8 is connected to the flat cable 3, the flat cable 3 is independently provided with a cutoff portion 10 on the tip end side of the flat cable 3 in the flat insulating coating 2 between the adjacent flat conductors 1. The flat cable portion 3A is formed.

Further, in the flat cable connection terminal 8, as shown in FIGS. 7A and 7B, the standing width of the crimp piece 6 in the width direction of the terminal plate portion 5 is the flat conductor 1 of the flat cable portion 3A. Is set to Wc so that the flat plate portion 3A can be held in the width direction, and the standing width of the holding piece 7 in the width direction of the terminal plate portion 5 is set to Wi that is wider than Wc. There is.

The terminal connection portion 9 is formed by piercing the crimp piece 6 of the flat cable connection terminal 8 into the flat cable portion 3A at a position corresponding to the flat conductor 1 to connect the corresponding flat conductor 1 and the connection terminal 7. The crimp pieces 6 that pass through the flat cable portion 3A are bent, and the tip portions of the crimp pieces 6 are bent and swaged so that the flat cable portion 3A is present between the adjacent holding pieces 7 and the tip side of these holding pieces 7 is bent. By doing so, the flat cable portion 3A is held by the tip portion of each holding piece 7 and the terminal plate portion 5.

At this time, the method of piercing and crimping the crimp piece 6 into the flat cable portion 3A and the method of crimping the holding piece 7 to the flat cable portion 3A are performed by using the flat cable receiving metal fitting 11 shown in FIG. Is going. This flat cable receiving fitting 11 has a flat cable portion 3A.
On the receiving surface, a pair of crimp piece receiving grooves 12 are provided on both sides of the partitioning protrusion 13 so as to fit within the width of the flat conductor 1, and the flat cable portion 3A is separated from the pair of crimp piece receiving grooves 12. Holding piece receiving groove 14 within the width of
Is provided on both sides of the partition protrusion 15.

The flat cable portion 3A is positioned with respect to the flat cable receiving metal fitting 11 as shown by a broken line, and each crimp piece 6 and each holding piece 7 of the connecting terminal 7 are crimp piece receiving groove 12 of each crimp piece 6. The flat piece 3A is pierced at the position of each of the holding pieces 7 and the holding pieces 7 are positioned at both sides of the flat cable portion 3A at the holding piece receiving groove 14, and then the tips of the crimp pieces 6 that penetrate the flat cable portion 3A The terminal piece 9 is formed by bending in a circular arc shape and caulking, and also bending the tip side of each holding piece 7 to hold the flat cable portion 3A.

The specific steps will be described with reference to FIGS. 9 (A) to 9 (F).

In the flat cable portion 3A, as shown in FIG. 9 (A), the flat conductor 1 is a pair of crimp piece receiving grooves 1 of which one is a pair.
2 is arranged below the flat cable receiving metal fitting 11 so as to exist, and in such a state, the anvil 16 is raised by the guide of the guide member 17, and the flat cable connecting terminal 8 is raised by the rise of the anvil 16. Each crimp piece 6 is pierced into the flat cable portion 3A at the location of the flat conductor 1.

As a result, as shown in FIG. 9B, each crimp piece 6 is pierced by the flat cable portion 3A at the location of the flat conductor 1 and becomes conductive with the flat conductor 1 and the tip portion of each crimp piece 6 is brought into contact therewith. Is the flat cable section 3
It is led out on the opposite side of A and fits into the pair of crimp piece receiving grooves 12.

At the same time as this step, as shown in FIG. 9 (D), each holding piece 7 also rises due to the rise of the flat cable connecting terminal 8 accompanying the rise of the anvil 16, and as shown in FIG. 9 (E). As the holding pieces 7 enter the holding piece receiving grooves 14, the flat protrusions 3A are pushed by the partitioning projections 15 and are inserted between the holding pieces 7.

After that, the flat cable receiving fitting 11
To remove the tip end of each crimp piece 6 from each crimp piece receiving groove 12 and then the flat cable receiving metal fitting 1
1 is moved in the horizontal direction, and at the position where the tip of each crimp piece 6 faces the crimp piece bending caulking concave portion 18 shown in FIG. 9 (C) provided at another place of the flat cable receiving metal fitting 11. After stopping, the flat cable receiving metal fitting 11 is lowered at such a position, and the tip end portion of each crimp piece 6 is bent in the crimp piece bending crimping concave portion 18 as shown in FIG. .

Further, along with this step, the flat cable receiving metal fitting 11 is lifted to remove the tip end of each holding piece 7 from each holding piece receiving groove 14, and then the flat cable receiving metal fitting 11 is moved in the horizontal direction to hold each holding piece. Piece 7 is holding piece receiving groove 1
9 (F) provided at a position different from 4 and is stopped at a position facing the holding piece bending caulking concave portion 18 shown in FIG. As shown in FIG. 10B, the holding piece curved crimping concave portion 19 is bent and crimped in an arc shape.

[0015]

However, in the conventional flat cable connecting terminal 8, as shown in FIG. 11, the size of each holding piece 7 is sufficient to secure a sufficient crimping margin of the flat cable portion 3A. From the size of piece 6 h1
It was only high. Therefore, when the crimp pieces 6 are pierced into the flat cable portion 3A, the holding pieces 7 always come into contact with the flat cable portion 3A first, so that the crimp pieces 6 are pierced into the correctly positioned flat cable portion 3A. Before, the flat cable portion 3A itself may move or be displaced, so that the crimp pieces 6 do not pierce the flat conductor 1 at the correct position, and as shown in FIG.
There is a problem in that the flat cable portion 3A is pierced at an insulation position outside the above range, electrical continuity with the flat conductor 1 is not sufficiently obtained, and the connection reliability is reduced.

An object of the present invention is to provide a connecting method and a connecting device for a flat cable and a flat cable connecting terminal, in which the holding piece does not obstruct the crimp piece and the flat cable can be properly pierced into the flat cable.

[0017]
