And the unnecessary portion 103c on the right side of the tab terminal 101f are punched at the same time.

【発明が解決しようとする課題】従来、タブ端子１０１
の幅は２．３mm以上が主流であったが、近年、ヒューズ
の細分化や圧接コネクタの普及により１．３mmや１．０
mm幅のタブ端子１０１が必要になってきている。Conventionally, the tab terminal 101 is used.
The width of 2.3 mm or more was the mainstream, but in recent years, due to the subdivision of fuses and the spread of pressure contact connectors, 1.3 mm and 1.0
The tab terminal 101 having a width of mm is required.
【０００６】しかしながら、タブ端子１０１の幅が狭く

る。However, when the width of the tab terminal 101 becomes narrow, a blade of a thin press die is required to manufacture the tab terminal 101. In addition, when the area of the portions (unnecessary portions 102a to 102c, 103a to 103d) to be punched by the press die is large, the load applied to the press die during punching becomes large. Therefore, when both side walls of each tab terminal 101 are formed by punching at once, the blade of the press die spills and the life of the press die is shortened. Therefore, as described above, the one side wall of each tab terminal 101 is punched and formed, and then the other side wall of the tab terminal 101 is punched and formed, thereby extending the life of the press die.

る。By the way, since the unnecessary portions 102a to 102c are removed in the first punching formation, each tab terminal 101 is drawn to the press die in the second punching formation. As a result, as shown in FIG. 5C, the tab terminal 101 tilts to the left and right, and a dimensional error t1 occurs. Further, as shown in FIG. 5D, the tab terminal 101
In, the cross-sectional shape of the portion drawn to the press die becomes thin, and the deformed portion 104 occurs. Then, as shown in FIG. 6, when the root portion 105 of the tab terminal 101 is bent in this state, each tab terminal 101 tilts toward the deforming portion 104, and a dimensional error t2 occurs. As a result, a large dimensional error t3 (= t1 + t2), which is the sum of the dimensional errors t1 and t2, occurs in the tab terminal 101.

One side wall of the tip portion 10a of (11 to 16) is punched out. That is, the unnecessary portion 3a between the tab terminal 11 and the tab terminal 12, the unnecessary portion 3b between the tab terminal 13 and the tab terminal 14, and the unnecessary portion 3c between the tab terminal 15 and the tab terminal 16 are simultaneously punched and formed.

い。Subsequently, as shown in FIG. 1B , the other side wall of the tip end portion 10a of each of the plurality of tab terminals 11 to 16 is punched out. That is, the unnecessary portion 4a on the left side of the tab terminal 11, the unnecessary portion 4b between the tab terminal 12 and the tab terminal 13, the unnecessary portion 4c between the tab terminal 14 and the tab terminal 15, and the unnecessary portion on the right side of the tab terminal 16. 4d is punched and formed at the same time. At this time, the tip portion 1 of each tab terminal 10
0a are connected to each other via the connecting portion 2.
Therefore, even if the force of pulling each tab terminal 10 to the press die is exerted at the time of punching formation, each tab terminal 10
The front end portion 10a of each of the tab terminals 10 is locked by the connecting portion 2, and the tab terminals 10 are not pulled to the press die. Therefore, each tab terminal 10 does not tilt to the left and right, and
The dimensional error t1 as shown in (c) does not occur.

設定されている。Next, as shown in FIG. 1C, the unnecessary portion 5 between the root portions 10b of the plurality of tab terminals 10 is punched and formed at once with a press die. The area of the unnecessary portion 5 between the root portions 10b is set smaller than the area of the unnecessary portions 3a to 3c and 4a to 4d. Therefore, even if both side walls of the root portion 10b of each tab terminal 10 are formed by punching at once, no blade spill of the press die occurs. To put it the other way around, the area of the unnecessary portion 5 is set so that even if the unnecessary portion 5 is punched and formed at once, the blade of the press die does not spill.

可能性がある。Subsequently, as shown in FIG. 1D, the connecting portion 2 is separated from each tab terminal 10. Here, since both side walls of the root portion 10b of each tab terminal 10 are formed by punching at once, the both side walls are attracted to the press metal.
As a result, as shown in FIG. 2, deformed portions 10c are formed on both side walls of the root portion 10b of each tab terminal 10. However, since the force from the press die is evenly applied to both side walls of the root portion 10b of each tab terminal 10, the deformation degree of the deformation portion 10c is smaller than that of the deformation portion 104 shown in FIG. 5D. It will be very small. Therefore, even if bending is performed in this state, a large dimensional error t3 as shown in FIG. 6 does not occur in each tab terminal 10. However, since there is a small deformed portion 10c, the root portion 10b of each tab terminal 10 is
A slight dimensional error may occur during the bending process.

The root portion 10b of each tab terminal 10 has a substantially quadrangular cross section. In that state, as shown in FIG. 3, each tab terminal 10
At the root portion 10b of the tab terminal 10, a line extending in the width direction of the tab terminal 10 is
When the bending process is performed in the connector, each tab terminal 10 having high dimensional accuracy can be obtained.

タブ端子の製作方法。 1. By punching out unnecessary parts
A first step of punching and forming only the tip portions of the tab terminals in a state where the tip portions of the tab terminals are connected by the connecting portion; and a second step of punching and forming the root portions of the tab terminals by punching and forming unnecessary portions . A step, a third step of separating the connecting portion from the tip portion, and a fourth step of bending the tab terminal at the root portion , and the first step includes tip portions of a plurality of tab terminals. One side wall
After punching at the same time, the tips of multiple tab terminals
The other side wall of the part is punched at the same time.
In the second step, the unnecessary portion of the root of each of the plurality of tab terminals is
At a time with an area smaller than the unnecessary portion of the tip of the tab terminal
Punch and form both side walls at the base of the tab terminal.
That is, following the third step, the cross-sectional shape of the root portion of each tab terminal
Is pressed to make it approximately square and bent at the line extending in the width direction of each tab terminal.
The width of the peeled root is set wider than the width of the tip
How to make tab terminals.
