The widened portion 12 formed in this way is configured as a step of integrally forming the shaft-shaped portion 11. In this widened portion forming step S101, as shown in FIG. 10 (b), the end portion on the tip side of the shaft-shaped member 20 fed out from the reel 21 is subjected to press work, and has an elliptical outer shape. The widened portion 12 is formed in a flattened state where no hole 12a is formed.

  In the drilling step S102, as shown in FIG. 10 (c), the hole 12a is formed on the widened portion 12 formed on the end of the shaft-like member 20 on the front end side and flattened in an elliptical shape. Processing is performed. The hole 12a is formed by forming a cut with respect to the center of the widened portion 12 that is flattened into an elliptical shape and expanding the cut portion.

  In the length measuring step S103, a length dimension necessary for the press-fit terminal 2 is measured from the end on the tip side of the shaft-like member 20 in which the widened portion 12 is formed at the end on the tip side.

  In the cutting step S104, the shaft-shaped member 20 is cut so that the press-fit terminal 2 having the length measured in the length measuring step S103 is obtained. Thereby, as shown in FIG.10 (d), the shaft-shaped part 11 will be isolate | separated from the shaft-shaped member 20 comprised as a wire or a bar with which the plating layer which coat | covers the surface was formed. And the plating layer which coat | covered the surface is formed in the surrounding side surface of the shaft-shaped part 11 and the wide part 12 before the wide part 12 is formed. The end portion of the shaft-shaped portion 11 cut from the shaft-shaped member 20 constitutes the other end portion 11a described above.

  In the stepped portion forming step S <b> 105, the stepped portion 13 to which a biasing force is applied when the widened portion 12 is press-fitted into the substrate 100 is formed by forming the stepped portion in the shaft-shaped portion 11. It is comprised as a process formed integrally. In the stepped portion forming step S105, the stepped portion 13 including the bent portion 13a is formed by performing a bending process at a position near the widened portion 12 in the shaft-shaped portion 11.

  A plurality of press-fit terminals 2 are manufactured by repeating the steps (S101 to S105) described above. Then, the shaft-shaped member 20 wound around the reel 21 is sequentially drawn out from the reel 21, and the steps (S101 to S104) from the widened portion forming step S101 to the cutting step S104 are repeatedly performed. The plurality of press-fit terminals 2 are press-fitted into the respective through holes of the housing 3 and are held by the housing 3 as described above. Then, the other end 11a side of the shaft-like portion 11 in each press-fit terminal 2 press-fitted into each through hole of the housing 3 is bent, and the connector 1 is completed.

  As described above, according to the present embodiment, a plating layer covering the surface before the widened portion 12 is formed is formed on the peripheral side surfaces of the shaft-shaped portion 11 and the widened portion 12. The shaft-shaped member 20 configured as a wire or a rod with a plating layer covering the surface is separated. For this reason, the plating process process after the member corresponding to the press fit terminal 2 is isolate | separated becomes unnecessary. Therefore, since the plating process process which performs a plating process separately on a small member becomes unnecessary, the increase in a manufacturing man-hour can be suppressed and manufacturing cost can also be reduced. Further, in the press-fit terminal 2, the shaft-like portion 11 in which the widened portion 12 and the step-like portion 13 are integrally formed is separated from the shaft-like member 20 configured as a wire or a rod, so that the material yield is increased. Will be improved.

  Furthermore, the press-fit terminal 2 is provided with a stepped portion 13 that is formed in a step shape in the shaft-shaped portion 11 and is formed integrally with the shaft-shaped portion 11. Then, by applying a biasing force to the stepped portion 13, the widened portion 12 formed integrally with the shaft-shaped portion 11 is press-fitted into the substrate. For this reason, it is possible to easily press-fit the press-fit terminal 2 into the substrate 100 by directly applying an urging force to the press-fit terminal 2. Therefore, it is possible to relax the restriction in the work process of press-fitting the press-fit terminal 2 into the substrate 100.

  Therefore, according to the press-fit terminal 2 of the present embodiment, the connector 1 of the present embodiment, and the manufacturing method, the material yield can be improved and the member corresponding to the press-fit terminal 2 is separated. A plating process is not required, and further, restrictions on the work process of press-fitting the press-fit terminal 2 into the substrate 100 can be relaxed.

  Further, according to the press-fit terminal 2, the stepped portion 13 is provided at a location close to the widened portion 12, so that an urging force can be efficiently applied when the widened portion 12 is press-fitted into the substrate 100. it can.

  Moreover, according to the press-fit terminal 2, the widening part 12 is formed in the shaft-shaped member 20 comprised as the wire or the bar in which the plating layer which coat | covers the surface was formed, and the widening part 12 is integrally formed after that. The formed shaft-shaped portion 11 is separated from the shaft-shaped member 20. For this reason, the work of forming the widened portion 12 and the work of separating the shaft-shaped portion 11 can be continuously and efficiently processed while sequentially feeding the shaft-shaped member 20. Therefore, the manufacturing efficiency of the press-fit terminal 2 can be improved.

  In addition, according to the press-fit terminal 2, the widened portion 12 can be easily and efficiently formed by pressing while the shaft-shaped member 20 is sequentially fed out. Therefore, the manufacturing efficiency of the press-fit terminal 2 can be further improved.

  According to the press-fit terminal 2, a hole 12 a is provided by forming a cut at the center of the widened portion 12 and further widening it. For this reason, in the widened portion 12 formed by press working, a structure that can secure a large amount of elastic deformation for improving the mountability when being press-fitted into the through hole 100a of the substrate 100 is easily achieved with a simple configuration. Can be realized.

  Further, according to the press-fit terminal 2, the stepped portion 13 includes the bent portion 13 a in the body portion of the shaft-like portion 11. Therefore, the stepped portion 13 to which the urging force can be easily applied can be realized with a simple structure, and the stepped portion 13 can be easily formed at a desired location in the trunk portion of the shaft-shaped portion 11. Therefore, the restrictions in the work process of press-fitting the press-fit terminal 2 into the substrate 100 can be further relaxed.

  Further, according to the press-fit terminal 2, the stepped portion 13 is formed only by bending the shaft-shaped portion 11, so that the stepped portion 13 can be formed more easily.

  Further, according to the connector 1, each press-fit terminal 2 is press-fitted perpendicularly to the substrate 100 at the widened portion 12, and with respect to the terminals of other connectors that fit into the housing 3 in a direction parallel to the substrate 100. The end portion on the opposite side to the widened portion 12 (the end portion 11a on the other side) can be connected. A connector 1 in which a plurality of press-fit terminals 2 are densely held in the width direction and the height direction of the housing 3 can be realized. Further, in the connector 1, a plurality of press-fit terminals 2 arranged side by side in the width direction of the housing 3 at the position where the other end 11 a side of the shaft-like portion 11 is adjacent to each other in the height direction of the housing 3 are provided. The housing 3 is disposed at a position shifted in the width direction so as not to overlap each other in a direction parallel to the height direction. For this reason, when the urging force for press-fitting the widened portion 12 of each press-fit terminal 2 into the substrate 100 is applied to the stepped portion 13, the other end 11 a side of the shaft-shaped portion 11 is in the height direction of the housing 3. The press-fit terminals 2 arranged at adjacent positions are unlikely to interfere with each other, and a space for applying an urging force to the stepped portion 13 can be easily secured.
