2. Description of the Related Art In a conventional method for manufacturing a connector connecting piece, a plan view of FIG. 4A shows a state in which a punching process is performed, and a certain pressure is applied to a corresponding connecting piece (not shown). Contact portion 31 having a length L to be contacted by
And a state in which a plurality of connection pieces 37 each formed of a connection portion 32 having a length M that is a portion around which a conductive wire is wound when used as a connector are punched out of a metal plate. Here, the carrier 34 is a portion where the metal plate is mounted on the punching press and the metal plate is moved, and the metal plate is fed in a direction of an arrow, for example, by using holes at a predetermined pitch N and punched out. Here, the pitch 33 and the gap 3 between the connection piece 37 punched perpendicularly to the end face 38 of the carrier and the adjacent connection piece 37 are provided.
6 is made as narrow as possible as long as the conditions for reducing the waste material of the metal plate and the size of the punching die of the punching press allow. The half cut 35 is a portion to be cut off as a connection piece 37 of an individual piece, and has a slightly cut shape. Finally, the carrier 34 at the half cut 35
Then, as shown in the plan view of FIG. 4B, the connection piece 37 is manufactured as an individual piece.

[0005] Next, a method of assembling the connection piece 37 into a connector is performed by arranging a required number of holes 38 provided in a connector body 37 formed of resin or the like as shown in a perspective view of FIG. The connection piece 37 is inserted into these holes 38 by one.
It was press-fitted individually. Therefore, the pitch 15B of the holes in the connector body is different from the pitch 33 between the connecting pieces in FIG. 4A, and the pitch 33 is set to a narrow width in order to reduce waste material.

[0004]

In this conventional method of manufacturing a connector connecting piece, a large number of steps are required since the connecting piece is cut off from the carrier and the single piece is pressed into the hole of the connector. There is a disadvantage that the assembly efficiency is poor.

An object of the present invention is to provide a method for producing a plurality of connecting pieces with as little waste material as possible. In addition, the connection piece of the connector, taking into account the step of incorporating in advance connector

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a plan view of an embodiment of the present invention, and FIG.
(A) shows a state in which a plurality of connection pieces 10 each including a contact portion 11 and a connection portion 12 are punched out of a metal plate by a punching press. FIG. 1B shows a state in which a plurality of connection pieces 10 punched out in FIG. 1A are bent. FIG. 2 shows FIG.
It is explanatory drawing which shows the assembling process which press-fits the several connection piece 10 with the carrier 14 of the state of (b) being connected in the corresponding hole 38 of a connector main body.

[0008] Next, the manufacturing process of the present embodiment is described first with reference to FIG.
In FIG. 2A, a plurality of connecting pieces 10 punched from a metal plate have an integral structure with a carrier 14. Each connecting piece 10 holds a predetermined gap 16 and
4 are arranged at an angle θ smaller than 90 ° with respect to the end face 18. The angle θ has a value as small as possible within a range in which there is no breakage due to bending in the bending step described with reference to FIG. 1B and the pitch 15A between the connection pieces can maintain a predetermined dimension described later. Here, assuming that the width of the metal plate to be stamped is the length L + M of the connection piece, (L + M) Sin θ
And the interval 16 is small, so that the smaller the angle θ, the less the metal plate material and waste material.

Next, in the bending step shown in FIG. 1 (b), each connection piece 10 has a connection portion 11 having a length L and a connection portion 12 having a length M having the same functions as the conventional example. And a half cut 13 serving as a cutting portion, and a carrier 14 integrated with each connection piece 10. Here, the bent portion 17 of the connecting piece 10 is a place where the center line of each connecting piece 10 is bent so as to be perpendicular to the end face 18 connecting the connecting pieces of the carrier 14. In this bent state, the pitch 15A is the pitch 15B of the hole of the connector 37 described later.
It is formed in the same size as.

Next, the assembly process will be described with reference to FIG. The connector body 37 has the same structure as the conventional example shown in FIG. 5, but only four holes 38 corresponding to the connection pieces 10 are shown. Here, the pitch 15B between the centers of the adjacent holes 38 is the same as the pitch 15A of the adjacent connecting pieces 10. Therefore, the plurality of connection pieces 10 connected to the carrier 14 can be formed in the corresponding holes 38 by one press-fitting operation.
Is inserted into. After the press-fitting operation is completed, the plurality of connection pieces 10 are cut at a half cut 13 by one cutting operation. As described above, the work of the assembling process is greatly simplified. As a means for reducing waste materials due to punching in the first manufacturing process, as shown in the plan view of FIG. 3, a plurality of connection pieces 21 and connections 22 respectively connected to carriers 23 and 24 are provided with a gap. There is also a method of alternately arranging them using the number 25. However, in this case, the pitch 15A between the connecting pieces 10 needs to be matched with the pitch 15B of the hole of the connector as described above, so that the width of the connecting pieces fits between the gaps 25, and the punching die has room. Limited to certain cases. In this case, the bending step described above is of course unnecessary.

[0011]

As described above, according to the present invention, a step of forming a connecting piece at an angle with a carrier, a step of bending near a connecting portion between the carrier and the connecting piece, and a step of attaching to a carrier are provided. By adopting a manufacturing method that employs an assembling step of inserting a plurality of connection pieces as they are into the hole of the connector by a single press-fitting operation, it is possible to reduce the amount of metal sheet material for punching and waste material for punching. Further, there is an effect that the number of steps required for inserting the connecting piece in the assembling process can be significantly reduced.
