[0010] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be listed and described.

[0011] The press-fit terminal of the present disclosure is as follows.

[0012] (1) A press-fit terminal including a conductive wire connection part connected to a conductive wire and a press-fit part inserted into a press-fit hole, wherein the thickness of the conductive wire connection part is different from the thickness of the press-fit part.

[0013] According to the present disclosure, by making the thickness of the conductive wire connection part different from the thickness of the press-fit part, the thickness suitable for connecting the conductive wire connection part to the conductive wire can be achieved, and the thickness suitable for press-fitting and connecting the press-fit part into the press-fit hole can be achieved. Thereby, the connectivity of the press-fit terminal to the conductive wire and the press-fit hole can be further improved.

[0014] (2) The press-fit terminal according to (1), wherein the thickness of the conductive wire connection part may be smaller than the thickness of the press-fit part.

[0015] By relatively increasing the thickness of the press-fit part, the thickness suitable for press-fitting and connecting the press-fit part into the press-fit hole can be achieved. Also, by relatively reducing the thickness of the conductive wire connection part, the thickness suitable for connecting the conductive wire connection part to the conductive wire can be achieved.

[0016] (3) The press-fit terminal according to (2), wherein the conductive wire connection part may include a conductive wire crimping part that is crimped and connected to the conductive wire.

[0017] The conductive wire crimping part with a relatively small thickness can be easily deformed according to the thickness of the conductive wire. Therefore, the conductive wire crimping part is well crimped to the conductive wire.

[0018] (4) Any one of the press-fit terminals from (1) to (3), wherein the thickness change step may be located away from the conductive wire connection part toward the press-fit part side.

[0019] By using the thickness change step as a guide, and positioning the tip of the conductive wire closer to the press-fit section than the conductive wire connection section, it becomes easier to connect the conductive wire to the conductive wire connection section.

[0020] (5) A press-fit terminal according to any one of (2) to (4), wherein the thickness change step is located away from the conductive wire connection portion on the press-fit portion side and on the side of the conductive wire connection portion where the conductive wire is arranged.

[0021] By utilizing the thickness change step, the tip of the conductive wire is positioned closer to the press-fit section than the conductive wire connection section, making it easier to connect the conductive wire to the conductive wire connection section.

[0022] (6) A press-fit terminal according to any one of (2) to (5), further comprising a protruding piece located between the conductive wire connection portion and the press-fit portion, wherein a thickness-changing step may be located on the conductive wire connection portion side of the protruding piece portion.

[0023] In this case, the thickness of the protruding portion can be made relatively larger. Therefore, the process of pressing the press-fit portion into the press-fit hole can be easily performed using the protruding portion.

[0024] Furthermore, the wiring components of this disclosure are as follows:

[0025] (7) A wiring component comprising a first press-fit terminal, a second press-fit terminal, and a conductive wire, wherein each of the first press-fit terminal and the second press-fit terminal is one of the press-fit terminals from (1) to (6), and the conductive wire includes a first end connected to the first press-fit terminal and a second end connected to the second press-fit terminal.

[0026] The first and second press-fit terminals are connected via a conductive wire. Therefore, the relative positions of the first and second press-fit terminals can be easily adjusted. The wiring component can be used to connect components in various layouts.

[0027] [Details of the embodiments of this disclosure] Specific examples of the press-fit terminals and wiring components of this disclosure are described below with reference to the drawings. However, this disclosure is not limited to these examples and is intended to include all modifications within the meaning and scope of the claims as indicated by the claims.

[0028] [Embodiment 1] The press-fit terminal according to Embodiment 1 will be described below. Figure 1 is a plan view showing the press-fit terminal 20. Figure 2 is a side view showing the press-fit terminal 20. Figure 3 is a rear view showing the press-fit terminal 20. Figure 4 is a plan view showing the press-fit terminal 20W with conductive wire. Figure 5 is a side view showing the press-fit terminal 20W with conductive wire. Figure 6 is a cross-sectional view taken along line VI-VI in Figure 4. Note that dimensions may be exaggerated in each figure for ease of understanding. For example, the thickness is exaggerated compared to the width and longitudinal length.

[0029] The press-fit terminal 20 comprises a conductive wire connection portion 28 and a press-fit portion 22.

[0030] The conductive wire connection portion 28 is connected to the conductive wire 10. The press-fit portion 22 is inserted into the press-fit hole 16h (see Figure 4). A conductive layer 15 is formed on the inner circumference of the press-fit hole 16h.

[0031] When the press-fit portion 22 is pressed into the press-fit hole 16h, the conductive wire 10 and the conductive layer 15 are electrically connected via the press-fit terminal 20.

[0032] The press-fit terminal 20 is formed, for example, by press-forming a metal plate. In other words, the conductive wire connection portion 28 and the press-fit portion 22 are each part of a single, continuously connected metal plate. The metal plate is made of a metal such as copper or a copper alloy. A plating layer of tin, a tin alloy, or the like may be formed on the surface of the press-fit terminal 20.

[0033] With the press-fit portion 22 inserted into the press-fit hole 16h, the press-fit portion 22 is pressed against the inner circumferential surface of the press-fit hole 16h. This keeps the press-fit portion 22 inserted into the press-fit hole 16h. In addition, the press-fit portion 22 and the conductor layer 15 are kept in contact and electrically connected.

[0034] Here, the press-fit hole 16h is, for example, a hole formed in the circuit board 14. The conductive layer 15 is electrically connected to the circuit formed in the circuit board 14. Therefore, the conductive wire 10 and the circuit formed in the circuit board 14 are electrically connected via the press-fit terminal 20.

[0035] The press-fit hole 16h is, for example, a through-hole that penetrates the circuit board 14. The press-fit hole 16h may also be a bottomed hole.

[0036] More specifically, the press-fit portion 22 is formed in an elongated plate shape that extends in a straight line overall.

[0037] The press-fit portion 22 includes a tip portion 22a and a wide portion 22b. The tip portion 22a extends from the wide portion 22b on the opposite side of the conductive wire connection portion 28. The wide portion 22b is narrower than the tip portion 22a. An elongated opening 22bs is formed in the center of the width direction of the wide portion 22b. The opening 22bs is sometimes called an eye hole.

[0038] The width of the wide portion 22b is greater than the inner diameter of the press-fit hole 16h. The width of the tip portion 22a is smaller than the inner diameter of the press-fit hole 16h. When the press-fit portion 22 is inserted into the press-fit hole 16h, both sides of the wide portion 22b come into contact with the inner circumferential surface of the press-fit hole 16h. As the press-fit portion 22 is inserted, the wide portion 22b deforms in such a way that it narrows the width of the opening 22bs and reduces the width of the wide portion 22b. Then, with the wide portion 22b pressed into the press-fit hole 16h, the wide portion 22b is pressed against the conductive layer 15 on the inner circumferential surface of the press-fit hole 16h.

[0039] The conductive wire connection part 28 is the part that is connected to the conductive wire 10.

[0040] The conductive wire 10 may be the core wire in an insulated wire in which the core wire is covered with an outer covering, or it may be a bare conductor in which the entire core wire is exposed. The core wire may be a stranded wire or a single-core wire. The core wire may be made of copper, a copper alloy, aluminum, or an aluminum alloy. The conductive wire may be a braided wire, a circuit in an FPC (Flexible Printed Circuit), or a conductor in an FFC (Flexible Flat Cable).

[0041] The thickness tC of the conductive wire connection portion 28 and the thickness tP of the press-fit portion 22 are different.

[0042] For example, the thickness tP of the press-fit portion 22 is set to a size suitable for press-fitting into the press-fit hole 16h and for maintaining the press-fit state. Specifically, if the thickness tP of the press-fit portion 22 is too small, when the press-fit portion 22 is pressed into the press-fit hole 16h, the force pressing the press-fit portion 22 against the conductor layer 15 may be insufficient, or the force holding the press-fit portion 22 in the press-fit state may be insufficient.

[0043] By setting the thickness tP of the press-fit portion 22 to a size suitable for press-fit connection to the press-fit hole 16h, it is possible to reduce contact resistance, increase holding force, and achieve other improvements.

[0044] Furthermore, the thickness tC of the conductive wire connection portion 28 is set to a size suitable for connecting the conductive wire 10. For example, in this embodiment, the conductive wire connection portion 28 is a conductive wire crimping portion that is crimped to the conductive wire 10. For example, the conductive wire connection portion 28 is formed in a U-shape to be suitable for crimping to the conductive wire 10. With the conductive wire 10 placed inside the conductive wire connection portion 28, both sides of the conductive wire connection portion 28 are deformed so that they overlap the conductive wire 10 (see Figure 6). The conductive wire connection portion 28 is crimped to the conductive wire 10 by being surrounded between the central part in the width direction of the conductive wire connection portion 28 and both sides of the conductive wire connection portion 28.

[0045] In this case, the thickness tC of the conductive wire connection portion 28 is set to a size that allows it to deform to surround the conductive wire 10 according to the thickness of the conductive wire 10. For example, if the thickness of the conductive wire connection portion 28 is too large, it may be difficult for the conductive wire connection portion 28 to bend significantly to surround the conductive wire 10. Also, if the conductive wire connection portion 28 is bent too much, cracks may occur in the conductive wire connection portion 28. In particular, when the conductive wire 10 is thin, it is required to bend the conductive wire connection portion 28 significantly, that is, to bend it with a small radius of curvature.

[0046] Thus, the appropriate thickness for the press-fit portion 22 and the conductive wire connection portion 28 may differ depending on their respective roles. In this embodiment, if the press-fit portion 22 is too thin, the pressing force against the press-fit hole 16h will be insufficient, and if the conductive wire connection portion 28 is too thick, it may not be possible to properly crimp it to the conductive wire 10.

[0047] Therefore, the thickness tC of the conductive wire connection portion 28 is set to be smaller than the thickness tP of the press-fit portion 22. This makes it easier to crimp the conductive wire connection portion 28 to the conductive wire 10 while ensuring sufficient pressing force from the press-fit portion 22 when the press-fit portion 22 is pressed into the press-fit hole 16h.

[0048] Since the press-fit portion 22 and the conductive wire connection portion 28 have different thicknesses, a thickness-changing step 21 exists between the press-fit portion 22 and the conductive wire connection portion 28 to change the thickness.

[0049] The thickness-changing step 21 may be a step that is inclined with respect to the press-fit portion 22 and the conductive wire connection portion 28, or it may be a step that is perpendicular to the press-fit portion 22 and the conductive wire connection portion 28. The thickness-changing step 21 may be a flat surface, a curved surface, or a step that is a mixture of a flat surface and a curved surface.

[0050] In this embodiment, the thickness-changing step 21 is a step that includes a slope that gradually rises from the conductive wire connection portion 28 toward the press-fit portion 22.

[0051] The thickness-changing step 21 may be located at any position between the press-fit portion 22 and the conductive wire connection portion 28. The thickness-changing step 21 may be located at the edge boundary of the press-fit portion 22 on the side of the conductive wire connection portion 28, or at the edge boundary of the conductive wire connection portion 28 on the side of the press-fit portion 22, or between the edge boundary of the press-fit portion 22 and the edge boundary of the conductive wire connection portion 28.

[0052] The thickness-changing step 21 may be formed on any surface of the press-fit terminal 20. In this embodiment, it is formed on the surface of the press-fit terminal 20 on which the conductive wire 10 is placed. In this case, when placing the conductive wire 10 on the press-fit terminal 20, the positional relationship between the thickness-changing step 21 and the conductive wire 10 can be easily confirmed from the same surface.

[0053] In this embodiment, a connecting portion 24 exists between the press-fit portion 22 and the conductive wire connection portion 28. The connecting portion 24 is the part that connects the edge boundary of the press-fit portion 22 and the edge boundary of the conductive wire connection portion 28. In other words, the press-fit portion 22, the connecting portion 24, and the conductive wire connection portion 28 are arranged linearly in this order.

[0054] The connecting portion 24 is a narrow, elongated plate-like portion that is narrower than the wide portion 22b. In this embodiment, the width of the connecting portion 24 is the same as the width of the tip portion 22a.

[0055] The thickness-changing step 21 is located at the boundary between the conductive wire connection portion 28 and the connecting portion 24. More specifically, the thickness-changing step 21 is formed on an inclined surface that gradually rises from the boundary between the conductive wire connection portion 28 and the connecting portion 24 toward the connecting portion 24. In this embodiment, the portion of the connecting portion 24 that is closer to the press-fit portion 22 than the thickness-changing step 21 has the same thickness tP as the press-fit portion 22.

[0056] The tip of the conductive wire 10 may be located in front of the thickness change step 21, may be touching the thickness change step 21, or may be riding over the thicker portion beyond the thickness change step 21.

[0057] Furthermore, in this embodiment, the press-fit terminal 20 further includes a protruding piece portion 26 located between the conductive wire connection portion 28 and the press-fit terminal 20.

[0058] More specifically, a pair of protruding pieces 26 protrude from both sides of the longitudinal middle portion of the connecting portion 24. The protruding pieces 26 can be used to receive the pressing force for pressing the press-fit portion 22 into the press-fit hole 16h. For this purpose, the edge of the protruding piece 26 on the conductive wire connection portion 28 side should extend perpendicular to the longitudinal direction of the connecting portion 24. In this embodiment, the protruding piece 26 is rectangular in shape. The protruding piece 26 may also be triangular or have other shapes.

[0059] The thickness-changing step 21 may be located on the conductive wire connection portion 28 side of the protruding piece portion 26. In other words, the thickness-changing step 21 should be located between the protruding piece portion 26 and the conductive wire connection portion 28 in the longitudinal direction of the press-fit portion 22. In this case, it is easier to form the protruding piece portion 26 to the same thickness as the press-fit portion 22. If the thickness of the protruding piece portion 26 is large, the force when press-fitting the press-fit portion 22 can be more easily absorbed by the protruding piece portion 26.

[0060] With the press-fit portion 22 pressed into the press-fit hole 16h, the protruding portion 26 may be in contact with the substrate 14 or may be separated from the substrate 14.

[0061] In this embodiment, the thickness-changing step 21 is located at the boundary between the conductive wire connection portion 28 and the connecting portion 24. The thickness-changing step 21 may be located in the longitudinal middle portion of the connecting portion 24, between the base of the pair of protruding pieces 26 on the conductive wire connection portion 28 side. The thickness-changing step 21 may be located on the side of the protruding piece 26 that is further from the boundary between the conductive wire connection portion 28 and the connecting portion 24.

[0062] The presence of the protruding portion 26 is not mandatory, and it may be omitted. Furthermore, the protruding portion may be provided on the portion extending away from the press-fit portion 22 relative to the conductive wire connection portion 28.

[0063] The press-fit terminal 20 described above is formed, for example, by punching out a plate-shaped irregularly shaped sheet material in which portions of different thicknesses are adjacent to each other across a boundary line.

[0064] With the press-fit terminal 20 configured in this way, the thickness tC of the conductive wire connection portion 28 and the thickness tP of the press-fit portion 22 are different, making the conductive wire connection portion 28 suitable for connecting to the conductive wire 10 and the press-fit portion 22 suitable for press-fitting into the press-fit hole 16h. This further improves the connectivity of the press-fit terminal 20 to the conductive wire 10 and the press-fit hole 16h.

[0065] Furthermore, if the thickness tC of the conductive wire connection portion 28 is smaller than the thickness tP of the press-fit portion 22, the thickness of the press-fit portion 22 can be made relatively larger to a thickness suitable for press-fitting the press-fit portion 22 into the press-fit hole 16h. Also, by relatively reducing the thickness tC of the conductive wire connection portion 28, it is easier to make the conductive wire connection portion 28 a thickness suitable for connecting the conductive wire 10.

[0066] For example, let's assume that the conductive wire connection part 28 is a conductive wire crimping part that is crimped to the conductive wire 10. In this case, if the thickness tC of the conductive wire connection part 28 is relatively small, it is easier to deform the conductive wire connection part 28 so as to wrap around the conductive wire 10. For example, it is easier to bend the conductive wire connection part 28 to a small bending radius according to the thickness of the conductive wire 10. Also, even if the conductive wire connection part 28 is bent to a small bending radius, cracks are less likely to occur in the conductive wire connection part 28. For this reason, the conductive wire connection part 28 is easily crimped to the conductive wire 10.

[0067] For example, even if the conductive wire 10 is thin, the conductive wire connector 28 can be easily bent to a small bending radius in accordance with the thinness of the conductive wire 10, and the conductive wire connector 28 is firmly crimped to the thin conductive wire 10. If the conductive wire 10 is thin, the conductive wire 10 extending from the press-fit portion 22 can be easily routed according to the wiring path, making the wiring work easier.

[0068] Furthermore, if the conductive wire connection portion 28 is securely crimped to the conductive wire 10, the press-fit terminal 20 does not require an insulation barrel for crimping to the coating. However, the press-fit terminal may have an insulation barrel.

[0069] The appropriate thickness for connecting the conductive wire connection part 28 to the conductive wire 10 may vary depending on the configuration for the connection.

[0070] For example, the conductive wire 10 may be welded to the conductive wire connection portion 28. The welding may be ultrasonic welding, resistance welding, or laser welding. In these cases, if the conductive wire connection portion 28 is thin, it is easier to apply welding energy to the part where the conductive wire 10 and the conductive wire connection portion 28 are in contact. Therefore, when the conductive wire 10 and the conductive wire connection portion 28 are welded, if the thickness tC of the conductive wire connection portion 28 is smaller than the thickness tP of the press-fit portion 22, it is easier to weld the conductive wire connection portion 28 to the conductive wire 10.

[0071] Furthermore, since the thickness-changing step 21 is located on the conductive wire connection portion 28 side of the protruding piece portion 26, the thickness of the protruding piece portion 26 can be made relatively larger. Therefore, the process of press-fitting the press-fit portion 22 into the press-fit hole 16h using the protruding piece portion 26 can be easily performed.

[0072] Modified examples of this embodiment are shown in Figures 7 and 8. Figure 7 is a side view showing a modified press-fit terminal 120, and Figure 8 is a side view showing a press-fit terminal 120W with a conductive wire attached, to which a conductive wire 10 is connected.

[0073] In this press-fit terminal 120, the thickness-changing step 121 corresponding to the thickness-changing step 21 is located away from the conductive wire connection part 28, on the press-fit part 22 side.

[0074] Therefore, when placing the conductive wire 10 on the conductive wire connection part 28, it is easy to place the conductive wire 10 on the conductive wire connection part 28 using the thickness change step 121 as a guide. For example, it is easy to make the conductive wire 10 protrude from the conductive wire connection part 28 towards the press-fit part 22, and to position the tip surface of the conductive wire 10 at a fixed position using the thickness change step 121 as a reference.

[0075] In this state, connecting the conductive wire connector 28 to the conductive wire 10 makes it easier to stabilize the connection between the conductive wire connector 28 and the conductive wire 10.

[0076] Furthermore, if the thickness-changing step 121 is located on the side where the conductive wire 10 is placed, it is easy to simultaneously check the tip surface of the conductive wire 10 and the thickness-changing step 121 from the same direction.

[0077] Furthermore, the tip of the conductive wire 10 can be pressed against the thickness-changing step 121 to easily position the conductive wire 10.

[0078] These points also contribute to a more stable connection between the conductive wire connection part 28 and the conductive wire 10.

[0079] [Embodiment 2] The wiring component 200 according to Embodiment 2 will be described below. Figure 9 is a plan view showing the wiring component 200.

[0080] The wiring component 200 comprises a first press-fit terminal 20A, a second press-fit terminal 20B, and a conductive wire 10.

[0081] The first press-fit terminal 20A and the second press-fit terminal 20B may be the press-fit terminal 20 or the press-fit terminal 120.

[0082] The conductive wire 10 may be the core wire of an insulated electric wire.

[0083] One end of the conductive wire 10 is the first end 10a. The other end of the conductive wire 10 is the second end 10b.

[0084] A first press-fit terminal 20A is connected to the first end 10a. A second press-fit terminal 20B is connected to the second end 10b. In this embodiment, the first press-fit terminal 20A is crimp-connected to the first end 10a, and the second press-fit terminal 20B is crimp-connected to the second end 10b.

[0085] The conductive wire 10 is relatively easy to bend. If the conductive wire 10 is easily deformable, the positional relationship between the first press-fit terminal 20A and the second press-fit terminal 20B can be easily adjusted by deforming the conductive wire 10.

[0086] For example, as shown in Figure 10, suppose that the first press-fit terminal 20A of the wiring component 200 is press-fitted into the press-fit hole 16Ah formed in the first circuit board 14A, and the second press-fit terminal 20B is press-fitted into the press-fit hole 16Bh formed in the second circuit board 14B.

[0087] Let's assume that the first press-fit terminal 20A and the second press-fit terminal 20B are integrally formed from a metal plate. In this case, the first press-fit terminal 20A and the second press-fit terminal 20B are integrally connected via a relay portion formed from a metal plate.

[0088] Suppose the design has been modified so that the press-fit hole 16Bh is positioned significantly away from the position opposite the press-fit hole 16Ah compared to the original design. There is a limit to the amount of displacement of the intermediate section, and it may be difficult to accommodate the change in the positions of the press-fit holes 16Ah and 16Bh. In this case, it may be necessary to start the construction of a new mold in order to mold a wiring component in which the first press-fit terminal 20A and the second press-fit terminal 20B are integrally connected via the intermediate section.

[0089] According to this embodiment, the conductive wire 10 is easily deformable. For example, if the conductive wire 10 is a stranded wire, it is even more easily deformable. Therefore, by deforming the conductive wire 10 according to the relative positions of the press-fit holes 16Ah and 16Bh, the first press-fit terminal 20A can be press-fitted into the press-fit hole 16Ah, and the second press-fit terminal 20B can be press-fitted into the press-fit hole 16Bh. Furthermore, even if the press-fit holes 16Ah and 16Bh are far apart, this can be accommodated by changing the length of the conductive wire 10.

[0090] Furthermore, as shown in Figure 11, even if the second circuit board 14B is positioned so as to intersect the first circuit board 14A, for example, in an orthogonal position, the conductive wires 10 are arranged in a bent manner so that the first press-fit terminal 20A can be press-fitted into the press-fit hole 16Ah and the second press-fit terminal 20B can be press-fitted into the press-fit hole 16Bh.

[0091] Furthermore, as shown by the dashed line in Figure 11, even if the second circuit board 14B is placed next to the first circuit board 14A, the conductive wires 10 are arranged in a bent manner so that the first press-fit terminal 20A can be press-fitted into the press-fit hole 16Ah and the second press-fit terminal 20B can be press-fitted into the press-fit hole 16Bh.

[0092] Therefore, the wiring component 200 can easily accommodate changes in the positions of the press-fit holes 16Ah and 16Bh, improving the layout flexibility of the circuit boards 14A and 14B.

[0093] Furthermore, the above-mentioned wiring component 200 can easily accommodate positional errors in the press-fit holes 16Ah and 16Bh.
