DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, several embodiments for carrying out the present disclosure will be described. In each embodiment, parts corresponding to matters described in the preceding embodiment will be assigned the same reference numerals, and duplicate explanations may be omitted. In each embodiment, when only a part of the configuration is described, the other previously described embodiments may be applied to the other parts of the configuration.

[0015] In addition, it is not only possible to combine parts that are explicitly stated as being possible in each embodiment, but it is also possible to partially combine embodiments, embodiments and variants, and variants even if not explicitly stated, as long as there are no particular problems with the combination.

[0016] (First embodiment) An electric device 1 according to this embodiment will be described with reference to FIG. 1. The electric device 1 is applied to, for example, a vehicle control device. The electric device 1 includes a substrate 10, a terminal 40, and a fixing base 50. In describing the components included in the electric device 1, the thickness direction of the substrate 10 may be referred to as the Z direction. Two directions perpendicular to the thickness direction of the substrate 10 may be referred to as the X direction and the Y direction. The X direction and the Y direction are directions of maximum width in a through hole 12, which will be described later. In this embodiment, the maximum width corresponds to any diameter direction in the circular through hole 12. The X direction and the Y direction correspond to orthogonal directions. The Z direction corresponds to the thickness direction.

[0017] <Substrate> The substrate 10 includes an insulating base material 11, and electronic components and wiring patterns disposed on the base material 11. The substrate 10 has a flat shape with a small thickness in the Z direction. The substrate 10 has a front surface 10A and a back surface 10B that are spaced apart in the Z direction by the thickness of the substrate 10. The front surface 10A and the back surface 10B each extend along an XY plane that is perpendicular to the Z direction.

[0018] A through hole 12 is formed in the substrate 10, penetrating in the Z direction. The through hole 12 has openings 13A and 13B formed on the front surface 10A and back surface 10B. The opening 13A formed on the front surface 10A may be referred to as the front surface opening 13A. The opening 13B formed on the back surface 10B may be referred to as the back surface opening 13B. The through hole 12 has a substantially perfect circular shape in the XY plane.

[0019] A conductive member 14 is provided continuously on the inner wall 12A of the through hole 12, the edge of the front opening 13A, and the edge of the back opening 13B. The conductive member 14 is also referred to as through-hole plating. The main component metal of the plating may include at least one of Sn, Cu, Ni, Pd, and Ag. For ease of explanation, the portion of the conductive member 14 provided on the inner wall 12A may be referred to as the conductive inner wall 14A. The conductive inner wall 14A corresponds to the inner wall of the through hole 12. An elastic force is applied to the conductive inner wall 14A from the terminal 40.

[0020] <Terminal> The terminal 40 in the electrical device 1 includes a main body 20 and a relative mover 30. The main body 20 includes conductive terminals that are inserted into the through holes 12. The terminal 40 serves to electrically connect electronic components provided on the substrate 10 to external devices. The relative mover 30 has a shape that allows its position relative to the shaft 21 to be adjusted in the Z direction.

[0021] <Main body> The main body 20 includes a shaft 21 and four displacement portions 22. The shaft 21 and each of the four displacement portions 22 are made of metal. The shaft 21 and the four displacement portions 22 are continuous in the Z direction and made of a common material. The shaft 21 is columnar. The shaft 21 is cylindrical. The shaft 21 extends along the Z direction. The shaft 21 has a cylindrical shape. A cross section of the shaft 21 cut along a plane along the XY plane is circular. The shaft 21 has ends on both ends in the Z direction. The four displacement portions 22 are connected to one of the two ends, which is lower in the Z direction. Hereinafter, the end of the shaft 21 that is connected to the displacement portion 22 may be referred to as the tip portion 21A. The upper end of the shaft 21 opposite the tip portion 21A may be referred to as the base portion 21B. In this embodiment, an example will be described in which four displacement portions 22 are provided on the main body portion 20, but the number of displacement portions 22 is not limited to four. The number of displacement portions 22 may be at least two or more.

[0022] <Displacement section> Each of the four displacement portions 22 has an end portion at both ends in the Z direction. The ends of the four displacement portions 22 are continuous at the tip portion 21A by a common material. Each of the four displacement portions 22 extends from the tip portion 21A toward the base portion 21B. The portion of each of the four displacement portions 22 connecting the end on the tip portion 21A side with the end on the base portion 21B side is called an extension portion. The extension portions of the four displacement portions 22 are spaced apart by 90 degrees in the circumferential direction. The distance between any two adjacent displacement portions 22 among the four displacement portions 22 is equal. When the terminal 40 is viewed from the tip portion 21A side as shown in FIG. 2, the four displacement portions 22 and the tip portion 21A appear to form a cross.

[0023] Two of the four displacement portions 22 extend away from each other in the X direction from the shaft portion 21. Another two of the four displacement portions 22 extend away from each other in the Y direction from the shaft portion 21. Two of the four displacement portions 22 are arranged symmetrically with respect to the X direction with respect to the shaft portion 21. Another two of the four displacement portions 22 are arranged symmetrically with respect to the Y direction with respect to the shaft portion 21. The four displacement portions 22 are shaped so that they can be displaced away from each other. Each of the four displacement portions 22 is cantilevered by the tip portion 21A. Each of the four displacement portions 22 extends in the X direction or the Y direction at an angle away from the shaft portion 21. The outer circumferential length of the four displacement portions 22 along the circumferential direction increases from the tip portion 21A toward the base end portion 21B.

[0024] The four displacement portions 22 in the electric device 1 are combined to form an umbrella shape with the base widening from the tip end 21A to the base end 21B. The four displacement portions 22 are fixed to the tip end 21A like the ribs of an umbrella, and their extending portions are spaced apart from one another in the circumferential direction around the shaft portion 21. The four displacement portions 22 are spaced apart in the circumferential direction via slits. Like an umbrella, the four displacement portions 22 have a shape in which the width of the slits changes depending on the degree of opening in the X direction or Y direction. The multiple displacement portions 22 are spaced apart in the circumferential direction via slits whose width changes depending on the displacement in the X direction or Y direction.

[0025] Each of the four displacement portions 22 includes a lower displacement portion 22A and an upper displacement portion 22B that are connected in the Z direction. The lower displacement portion 22A and the upper displacement portion 22B each have ends at both ends in the Z direction. The end of the lower displacement portion 22A is connected to the tip portion 21A. The lower displacement portion 22A extends obliquely upward from the tip portion 21A toward the base end 21B, moving away from the shaft portion 21. Two of the four lower displacement portions 22A extend in different directions from each other in the X direction, from the tip portion 21A toward the base end 21B, gradually moving away from the shaft portion 21. Two of the four lower displacement portions 22A extend in different directions from each other in the Y direction, from the tip portion 21A toward the base end 21B, gradually moving away from the shaft portion 21. Two of the four lower displacement portions 22A are disposed symmetrically with respect to the shaft portion 21 in the X direction. Another two of the four lower displacement portions 22A are disposed symmetrically with respect to the shaft portion 21 in the Y direction.

[0026] Furthermore, an end of the upper displacement portion 22B is connected to an end of each of the four lower displacement portions 22A opposite to the end connected to the tip end portion 21A. Therefore, two of the four upper displacement portions 22B are arranged symmetrically with respect to the X direction with respect to the shaft portion 21. Another two of the four upper displacement portions 22B are arranged symmetrically with respect to the Y direction with respect to the shaft portion 21. The upper displacement portion 22B extends in the Z direction toward the base end portion 21B so as to move away from the lower displacement portion 22A. The upper displacement portion 22B extends in the Z direction from the end connected to the lower displacement portion 22A toward the end opposite to the end connected to the lower displacement portion 22A. In the electric device 1, the two upper displacement portions 22B arranged symmetrically with respect to the X direction with respect to the shaft portion 21 are separated by a constant first predetermined distance. In the electric device 1, the two upper displacement portions 22B arranged symmetrically with respect to the Y direction with respect to the shaft portion 21 are separated by a constant second predetermined distance equal to the first predetermined distance. Hereinafter, the first predetermined distance and the second predetermined distance may be collectively referred to simply as the predetermined distance.

[0027] The distance between the two displacing lower portions 22A arranged symmetrically with respect to the shaft portion 21 increases from the tip portion 21A toward the base portion 21B. In the electric device 1, the distance between the two displacing lower portions 22A arranged symmetrically with respect to the shaft portion 21 is a predetermined distance at the end portion connected to the displacing upper portion 22B. The distance between the two displacing upper portions 22B arranged symmetrically with respect to the shaft portion 21 is a predetermined distance as described above. The displacing portion 22 extends along the Z direction while bending between the displacing lower portion 22A and the displacing upper portion 22B.

[0028] <Relative mover> The relative mover 30 comprises a base 31 and a wedge portion 32. The relative mover 30 is formed from resin. The base 31 has ends at both ends in the Z direction. The wedge portion 32 is connected to the end of the base 31 on the lower side in the Z direction. The base 31 and the wedge portion 32 are made of a common material and are continuous in the Z direction. The base 31 is a cylinder extending in the Z direction. The wedge portion 32 has a mountain-like shape that narrows as it moves away from the end of the base 31 on the lower side in the Z direction. The relative mover 30 has a shape similar to a pencil holder, with the base 31 and the wedge portion 32 combined. If the relative mover 30 is likened to a pencil holder, the shaft portion 21 can be likened to the pencil lead.

[0029] The relative mover 30 has a cylindrical through-hole penetrating the interior from the base 31 to the wedge portion 32 in the Z direction. The base 31 has an opening in the Z direction at its upper end. The wedge portion 32 has an opening in the Z direction at its lower end away from the base 31. The opening in the Z direction at the upper end of the base 31 and the opening in the Z direction at the lower end of the wedge portion 32 are each circular in the XY plane. The opening at the upper end of the base 31, the opening at the lower end of the wedge portion 32, and the through-hole formed inside the relative mover 30 are connected in the Z direction to form a cylindrical shaft passage 31A through which the shaft 21 can pass. A cross section of the shaft passage 31A cut along the XY plane is circular.

[0030] <Fixed stand> The fixing base 50 includes a terminal fixing portion 51 that fixes the terminal 40 and a substrate fixing portion 52 that is fixed to the substrate 10. The terminal fixing portion 51 is plate-shaped and has a thickness in the Z direction. The terminal fixing portion 51 is provided with a fixing hole 51A through which the shank 21 passes and that determines the position of the shank 21 in the X and Y directions. This prevents the shank 21 from tilting relative to the Z direction. The position of the shank 21 in the X and Y directions may be determined by fixing the edge of the fixing hole 51A to the outer periphery of the shank 21. Furthermore, the terminal fixing portion 51 is provided with a push-in hole 51B at a position that is mutually adjacent to the base 31 in the Z direction, for inserting a push-in jig 70 (described later).

[0031] <Board and terminals> In the electrical device 1, the terminal 40 is inserted into the through hole 12 of the substrate 10. Specifically, the through hole 12 is provided with a tip portion 21A, a portion of the shank 21, four displacement portions 22, a portion of the base portion 31, and a wedge portion 32. The shank 21 is provided in the through hole 12 so that the tip portion 21A is flush with the rear surface opening 13B. The shank 21 is provided in the through hole 12 so that it passes through the center of the through hole 12 in the XY directions orthogonal to the Z direction. The shank 21 is provided in the through hole 12 perpendicular to the rear surface opening 13B. The shank 21 extends along the Z direction.

[0032] The relative mover 30 is provided around the shaft portion 21 in the circumferential direction. The shaft portion 21 passes through the shaft portion passage 31A. The relative mover 30 has a shape that allows its relative position to be adjusted in the movement direction with respect to the shaft portion 21. The shaft portion 21 determines the position of the relative mover 30 in a direction perpendicular to the movement direction, and also serves as a guide in the movement direction. As described above, the shaft portion 21 extends in the Z direction. That is, the relative mover 30 has a shape that allows its relative position to be adjusted in the Z direction with respect to the shaft portion 21. The shaft portion 21 serves as a guide for movement of the relative mover 30 in the Z direction.

[0033] The four displacement portions 22 are shaped so as to be displaceable toward the conductive inner wall 14A. Because the relative mover 30 is provided around the shaft portion 21 in the circumferential direction, the four displacement portions 22 are spread out toward the conductive inner wall 14A. The four lower displacement portions 22A are spread out from the tip portion 21A in the X direction or Y direction toward the conductive inner wall 14A of the through hole 12. The upper displacement portions 22B are spread out in the X direction or Y direction toward the conductive inner wall 14A.

[0034] In the Z direction, the wedge portion 32 is provided closer to the tip portion 21A than the base portion 31. In the X and Y directions, the wedge portion 32 is provided between the displacing lower portion 22A and the shaft portion 21. Two displacing lower portions 22A aligned in the X direction are pressed against the conductive inner wall 14A in the X direction by the wedge portion 32. Two displacing lower portions 22A aligned in the Y direction are pressed against the conductive inner wall 14A in the Y direction by the wedge portion 32. In the electric device 1, the wedge portion 32 has a shape that allows the amount of displacement of the displacing lower portions 22A with respect to the conductive inner wall 14A to be determined depending on the relative position of the wedge portion 32 with respect to the shaft portion 21 in the Z direction.

[0035] Furthermore, the base 31 is located closer to the base end 21B than the wedge portion 32 in the Z direction. The base 31 is located between the displacement upper portion 22B and the shaft portion 21 in the X and Y directions. Two displacement upper portions 22B aligned in the X direction are pressed against the conductive inner wall 14A in the X direction by the base 31. Two displacement upper portions 22B aligned in the Y direction are pressed against the conductive inner wall 14A in the Y direction by the base 31. In the electric device 1, the displacement amount of the displacement upper portions 22B relative to the conductive inner wall 14A can be determined depending on the relative position of the base 31 with respect to the shaft portion 21 in the Z direction. In this way, the four displacement portions 22 are pressed against the conductive inner wall 14A by the relative mover 30. In the electric device 1, the displacement amount of the displacement portion 22 relative to the conductive inner wall 14A can be determined depending on the position of the relative mover 30 with respect to the shaft portion 21 in the Z direction.

[0036] The distance between two lower displacement portions 22A or upper displacement portions 22B aligned in the X direction is longer than the distance between two lower displacement portions 22A or upper displacement portions 22B aligned in the X direction before they are inserted into the through-holes 12. In other words, the distance between two displacement portions 22 aligned in the X direction is longer than the distance between two displacement portions 22 aligned in the X direction before they are inserted into the through-holes 12. The distance between two lower displacement portions 22A or upper displacement portions 22B aligned in the Y direction is longer than the distance between two lower displacement portions 22A or upper displacement portions 22B aligned in the Y direction before they are inserted into the through-holes 12. In other words, the distance between two displacement portions 22 aligned in the Y direction is longer than the distance between two displacement portions 22 aligned in the Y direction before they are inserted into the through-holes 12. The distance between two of the four displacement portions 22 aligned in the X or Y direction is equal to the diameter of the cross section of the relative mover 30 along the XY plane.

[0037] Furthermore, the displacement upper part 22B is formed with a first fitting portion 23 that is recessed from the opposing surface facing the base part 31 toward the rear surface behind the opposing surface. The first fitting portion 23 has a groove shape that extends along the outer periphery of the base part 31. Conversely, the base part 31 is formed with a second fitting portion 33 that protrudes from the outer surface facing the displacement upper part 22B toward the opposing surface. The second fitting portion 33 has a headband shape that extends around the entire periphery of the base part 31. In the electrical device 1, the first fitting portion 23 and the second fitting portion 33 are fitted together. By fitting the first fitting portion 23 and the second fitting portion 33 together, the position of the relative mover 30 in the Z direction is fixed.

[0038] <Terminal before being inserted into the through-hole> As shown in FIGS. 3 to 5, the terminal 40 before being inserted into the through-hole 12 has the same components as the terminal 40 included in the electric device 1. For ease of explanation, the terminal 40 before being inserted into the through-hole 12 may be referred to as the terminal 40 before being inserted. In the terminal 40 before being inserted, the four displacement lower portions 22A extend away from the shaft portion 21. In the terminal 40 before being inserted, the four displacement upper portions 22B extend toward the shaft portion 21. The four displacement portions 22 combine to form an umbrella shape different from that of the terminal 40 included in the electric device 1. In the terminal 40 before being inserted, the four displacement portions 22 are shaped so as to be displaceable toward or away from the shaft portion 21.

[0039] In the terminal 40 before insertion, the relative mover 30 is provided on the shaft 21 at a position closer to the base end 21B than the displacement portion 22. Alternatively, the relative mover 30 is provided on the shaft 21 with the wedge portion 32 hooked onto the displacement upper portion 22B. In the terminal 40 before insertion, the shaft 21 also determines the position of the relative mover 30 in a direction perpendicular to the direction of movement and serves as a guide in the direction of movement. In the terminal 40 before insertion, the shape allows the amount of displacement of the displacement portion 22 relative to the shaft 21 in the X or Y direction to be determined depending on the position of the relative mover 30 in the Z direction relative to the shaft 21. As shown in FIG. 4, when the terminal 40 before insertion is viewed from the tip end 21A side, the four displacement portions 22 and the tip end 21A appear to form a cross.

[0040] <Manufacturing methods for electrical equipment> The electric device 1 is manufactured through a plurality of steps including a jig step, a placement step, a movement step, and an approach step.

[0041] <Jig process> 6, in a jig process, a pressing jig 60 is placed on the back surface 10B side so as to close the back surface opening 13B. The pressing jig 60 is a jig for preventing the tip portion 21A of the shaft portion 21 from moving downward in the Z direction beyond the back surface opening 13B.

[0042] <Placement process> Next, in the placement process, the terminal 40 is placed in the through-hole 12 so that the shank 21 abuts against the holding jig 60. As shown in FIG. 7 , the terminal 40 is inserted into the through-hole 12 in the Z direction from the front opening 13A toward the holding jig 60 on the back opening 13B side. The shank 21 is inserted into the through-hole 12 until the tip 21A abuts against the holding jig 60. Note that in the placement process, the distance between opposing displacement portions 22 of the four displacement portions 22 placed in the through-hole 12 is smaller than the diameter of the through-hole 12. Also, the relative mover 30 has been passed through the shank 21 in advance. The wedge portions 32 fit between the four displacement upper portions 22B, and the position of the relative mover 30 in the Z direction with respect to the shank 21 is defined.

[0043] <Moving process> Next, as an example, the shaft portion 21 is fixed to the terminal fixing portion 51 on the base end portion 21B side of the relative mover 30 so that the shaft portion 21 is perpendicular to the holding jig 60. For example, the shaft portion 21 is passed through the fixing hole 51A, and the shaft portion 21 is fixed to the edge of the fixing hole 51A. In this way, with the relative mover 30 passed through the shaft portion 21, the shaft portion 21 is perpendicular to the holding jig 60. With the relative mover 30 passed through the shaft portion 21, the shaft portion 21 is fixed in a state extending along the Z direction.

[0044] Next, as shown in Figures 8 to 10, a pressing jig 70 is passed through pressing hole 51B formed in terminal fixing portion 51 from base end portion 21B toward tip end 21A. Pressing jig 70 is a jig for applying a load to relative mover 30 toward tip end 21A. When a load is applied from pressing jig 70 to relative mover 30 toward tip end 21A in the Z direction, wedge portion 32 moves further toward tip end 21A. Note that, because shaft 21 is passed through shaft passage 31A, relative mover 30 moves in the Z direction using shaft 21 as a guide to tip end 21A.

[0045] <Approach process> During the movement process, the relative mover 30 advances toward the tip end 21A using the shaft 21 as a guide, and during the approach process, the wedge 32 enters between the four displacement portions 22, displacing the displacement portions 22 in the X or Y direction. When the relative mover 30 advances toward the tip end 21A during the movement process, as shown in FIGS. 7 and 8, the upper displacement portions 22B are displaced in the X and Y directions toward the conductive inner wall 14A along the slopes connecting the top and bottom ends of the mountain-shaped wedge portions 32. Accordingly, the lower displacement portions 22A are also displaced in the X and Y directions toward the conductive inner wall 14A. The displacement portions 22 are displaced in the X and Y directions toward the conductive inner wall 14A.

[0046] As the relative mover 30 further advances toward the tip 21A, as shown in FIGS. 9 and 10 , the base 31 enters between the four upper displacement portions 22B, and the upper displacement portions 22B are further displaced in the X and Y directions toward the conductive inner wall 14A and come into contact with the conductive inner wall 14A. With the displaced upper displacement portions 22B in contact with the conductive inner wall 14A, the relative mover 30 pushes along the shaft 21 until the wedge portions 32 contact the lower displacement portions 22A. The pushing motion stops when the wedge portions 32 butt against the upper displacement portions 22B. At the position where the wedge portions 32 contact the lower displacement portions 22A, the upper displacement portions 22B come into contact with the conductive inner wall 14A over a wide area. The contact area between the upper displacement portions 22B and the conductive inner wall 14A is maximized.

[0047] Furthermore, at the same time that the wedge portion 32 contacts the lower displacement portion 22A, the first fitting portion 23 and the second fitting portion 33 are fitted together. This prevents the position of the relative mover 30 from fluctuating in the Z direction with respect to the shaft portion 21, even if the pushing jig 70 is removed after the approaching step. The position of the relative mover 30 is maintained in the Z direction. As a result, a force that expands the displacement portion 22 toward the conductive inner wall 14A continues to be generated. The contact between the displacement portion 22 and the conductive inner wall 14A is maintained.

[0048] In this embodiment, as described above, in the manufacturing process, the wedge portions 32 are inserted between the four displacement portions 22, and the displacement portions 22 are expanded toward the conductive inner wall 14A, thereby bringing the displacement portions 22 into contact with the conductive inner wall 14A. This prevents the displacement portions 22 from rubbing against the conductive member 14 and generating metal chips when the terminal 40 is inserted into the through hole 12. This also prevents the generation of unintended conductive paths due to the generation of metal chips.

[0049] <Action and effect> The relative mover 30 has an inner shaft passage 31A through which the shaft 21 can pass, and is shaped so that its relative position in the Z direction with respect to the shaft 21 can be adjusted. The relative mover 30 is provided with wedge portions 32 that fit between the four displacement portions 22 of the shaft and determine the positions of the displacement portions 22 with respect to the conductive inner wall 14A. The four displacement portions 22 are pushed and spread toward the conductive inner wall 14A by the wedge portions 32, thereby bringing the displacement portions 22 into contact with the conductive inner wall 14A. Because the relative mover 30 is passed through the shaft 21 extending in the Z direction, the relative mover 30 is prevented from being inserted obliquely into the through hole 12 with respect to the Z direction. The wedge portions 32 are prevented from being inserted obliquely between the four displacement portions 22 with respect to the Z direction. The relative positions of the conductive inner wall 14A and the displacement portions 22 are prevented from becoming uneven in the X and Y directions. This prevents uneven contact between the conductive inner wall 14A and the displacement portion 22. This prevents stress concentration in the displacement portion 22.

[0050] The displacement upper portion 22B is formed with a first fitting portion 23 that is recessed from the opposing surface facing the base portion 31 toward the rear surface behind the opposing surface. The base portion 31 is formed with a second fitting portion 33 that protrudes from the outer surface facing the displacement upper portion 22B toward the opposing surface. The first fitting portion 23 and the second fitting portion 33 are fitted together. This defines the position of the relative mover 30 in the Z direction relative to the shaft portion 21. Accordingly, the position of the displacement portion 22 relative to the shaft portion 21 is defined. Furthermore, it is possible to maintain the state in which the relative mover 30 is inserted into the shaft portion 21 along the Z direction. The uniformity of the contact state between the displacement portion 22 and the conductive inner wall 14A is maintained.

[0051] The shaft 21 is passed through the shaft passage 31A. The cross section of the shaft 21 taken along a plane along the XY plane is circular. The cross section of the shaft passage 31A taken along a plane along the XY plane is circular. As a result, even if the relative position between the relative mover 30 and the shaft 21 varies in the circumferential direction, the relative mover 30, which also has a circular cross section, is passed through the shaft 21, which has a circular cross section, so the relative mover 30 is prevented from getting caught on the shaft 21 in the Z direction. As a result, the relative mover 30 is prevented from being inserted into the through hole 12 at an angle with respect to the Z direction.

[0052] The shaft portion 21 and each of the four displacement portions 22 are made of metal. The relative mover 30 is made of resin. This prevents metal pieces from peeling off from the shaft portion 21 or the displacement portions 22 even if the shaft portion 21 or the displacement portions 22 rub against the relative mover 30 when the relative mover 30 moves in the Z direction to the tip end 21A using the shaft portion 21 as a guide during the manufacturing process. This prevents the formation of an unintended current path in the electric device 1 due to the peeled-off metal pieces.

[0053] The four displacement portions 22 are shaped like an umbrella, with slit widths that vary depending on the degree to which they open in the X and Y directions. The four displacement portions 22 are separated from one another via slits whose widths vary depending on their own displacements in the X and Y directions. This makes it possible to adjust the relative positions of the four displacement portions 22 in the X and Y directions when the relative mover 30 is inserted into the shaft portion 21 depending on the relative position of the relative mover 30 in the Z direction.

[0054] In the manufacturing method of the electrical device 1, the terminal 40 is provided perpendicular to the holding jig 60 with the relative mover 30 inserted through the shaft portion 21. The shaft portion 21 extends along the Z direction with the relative mover 30 inserted through the shaft portion passage 31A. Because the shaft portion 21 of the relative mover 30 is inserted through the shaft portion passage 31A, the shaft portion 21 can be used as a guide to move in the Z direction to the tip portion 21A. This prevents the relative mover 30 from being inserted obliquely into the through hole 12. In the subsequent approaching step, the displacement portion 22 is more likely to be displaced uniformly toward the conductive inner wall 14A in the X and Y directions. In the approaching step, the multiple displacement portions 22 are more likely to come into uniform contact with the conductive inner wall 14A in the X and Y directions. This helps prevent the electrical connection between the multiple displacement portions 22 and the conductive inner wall 14A from becoming unstable.

[0055] (Second embodiment) In the second embodiment, as shown in FIGS. 11 to 15, main body 20 includes shaft 21 and wedge 232. Shank 21 extends cylindrically in the Z direction. Wedge 232 is connected to tip 21A of shaft 21. Wedge 232 has a mountain-like shape that widens in a direction perpendicular to the Z direction as it moves away from tip 21A in the Z direction. In a cross section along the Z direction, shaft 21 and wedge 232 are joined together to form a broom-like shape in main body 20.

[0056] In the second embodiment, as shown in FIGS. 12 and 13, the relative mover 30 includes a base 31 and four displacement portions 222. The base 31 is a cylinder extending in the Z direction. The four displacement portions 222 are spaced apart from each other in the circumferential direction via slits. The four displacement portions 222 are shaped so that the width of the slits can be varied in accordance with their own displacement in a direction perpendicular to the Z direction. The four displacement portions 222 arranged in the circumferential direction are connected to the edge of the end portion located on the lower side of the base 31. As shown in FIG. 14, the space defined by the inner wall constituting the cylinder of the base 31 and the space defined by the inner walls of the four displacement portions are connected in the Z direction. This forms a shaft passage 31A through which the main body 20 can pass.

[0057] In the electric device 1 of the second embodiment, a terminal 40 is inserted into a through hole 12. A part of the shaft portion 21, a displacement portion 222, a part of the base portion 31, and a wedge portion 232 are provided in the through hole 12. A main body portion 20 is provided in the through hole 12 so as to pass through the center of the through hole 12 in the XY directions perpendicular to the Z direction. The wedge portion 232 is provided in the through hole 12 so that the end portion remote from the tip portion 21A is flush with the rear surface opening 13B. A relative mover 30 is provided around the shaft portion 21 and the wedge portion 232 in the circumferential direction. The main body portion 20 is passed through the shaft passage 31A.

[0058] In the electric device 1, the wedge portion 232 extends diagonally downward toward the conductive inner wall 14A as it moves away in the Z direction from the connection point with the base portion 31. Furthermore, the length between two opposing ones of the four displacement portions 22 is longer than the distance between the two opposing ones of the four displacement portions 22 before being inserted into the through-hole 12. The distance between two opposing ones of the four displacement portions 22 matches the diameter of the cross section of the wedge portion 232 along the XY plane.

[0059] In the second embodiment, the main body 20 also extends in the Z direction. The relative mover 30 has a shape that allows its relative position to be adjusted in the Z direction with respect to the main body 20. The main body 20 determines the position of the relative mover 30 in a direction perpendicular to the Z direction and also serves as a guide in the Z direction. Furthermore, in the Z direction, the wedge portion 232 is provided closer to the rear surface opening 13B than the shaft portion 21. In the direction perpendicular to the Z direction, the wedge portion 232 is provided between the four displacement portions 222. In the direction perpendicular to the Z direction, the wedge portion 232 is in contact with each of the four displacement portions 222. In the direction perpendicular to the Z direction, the two opposing displacement portions 222 are pushed apart toward the conductive inner wall 14A by the wedge portion 232.

[0060] Further, the displacement portion 222 is formed with a first fitting portion 223 that is recessed from the opposing surface facing the wedge portion 232 toward the rear surface behind the opposing surface. The first fitting portion 223 has a groove shape that extends along the outer periphery of the wedge portion 232. Conversely, the wedge portion 232 is formed with a second fitting portion 233 that protrudes from the outer surface facing the displacement portion 222 toward the opposing surface. The second fitting portion 233 has a headband shape that extends around the entire periphery of the wedge portion 232. In the electrical device 1, the first fitting portion 223 and the second fitting portion 233 are fitted together. This determines the position of the relative mover 30 in the Z direction. Accordingly, the position of the displacement portion 22 with respect to the main body portion 20 is determined.

[0061] Like the electric device 1 of the first embodiment, the electric device 1 of the second embodiment is manufactured through a plurality of steps including a jig step, an arrangement step, a movement step, and an approach step. As shown in Fig. 16, in the arrangement step, the terminal 40 is arranged in the through hole 12 so that the wedge portion 232 abuts against the holding jig 60. Note that in the arrangement step, the diameter of the wedge portion 232 arranged in the through hole 12 is smaller than the diameter of the through hole 12. Also, the relative mover 30 is passed through the shaft portion 21 in advance. The four displacement portions 222 cover the wedge portion 232, thereby defining the position of the relative mover 30 in the Z direction with respect to the main body portion 20.

[0062] Next, the shaft portion 21 is fixed perpendicular to the holding jig 60 by the same means as in the first embodiment. Then, in the moving step shown in FIGS. 17 and 18 , a load is applied to the relative mover 30 in the Z direction toward the holding jig 60 via the pressing jig 70. Then, the relative mover 30 moves along the wedge portion 232 to the holding jig 60, covering the wedge portion 232. The relative mover 30 moves in the Z direction using the shaft portion 21 and the wedge portion 232 as guides until it reaches the holding jig 60. At this time, in the approaching step, the displacement portion 22 is displaced in a direction perpendicular to the Z direction. Accordingly, the displacement portion 22 comes into contact with the conductive inner wall 14A. At this time, the first fitting portion 223 and the second fitting portion 233 are fitted together.

[0063] In the manufacturing method of the second embodiment, as shown in FIG. 19 , the electric device 1 can be manufactured without performing the jig process. In this case, in the arranging process, the main body 20 is arranged in the through-hole 12 so that the tip end 21A of the shaft 21 is provided in the through-hole 12. In the arranging process, the main body 20 is arranged in the through-hole 12 so that the wedge portion 232 is exposed from the rear opening 13B. The position of the main body 20 is then fixed using a fixing tool or the like. Next, the shaft 21 is passed through the shaft passage 31A from the base end 21B toward the wedge portion 232. When the relative mover 30 advances, using the shaft 21 as a guide, toward the end of the wedge portion 232 remote from the shaft 21, the relative mover 30 becomes caught on the wedge portion 232. In the arranging process, the relative mover 30 is held in a state in which it is provided on the shaft 21 closer to the base end 21B than the wedge portion 232. Then, the position of the relative mover 30 is fixed using a fixing tool or the like.

[0064] Next, in the moving step, the main body 20 is pulled up in the direction from the rear opening 13B toward the front opening 13A, using the shaft passage 31A as a guide. The shaft 21 moves along the shaft passage 31A in the direction from the rear opening 13B toward the front opening 13A. At this time, the wedge portion 232 enters the four displacement portions 222. In the approaching step, the diameters of the four displacement portions 222 expand in a direction perpendicular to the Z direction as the wedge portion 232 passes between the four displacement portions 222. The four displacement portions 22 approach the conductive inner wall 14A. Then, the four displacement portions 22 come into contact with the conductive inner wall 14A.

[0065] (Third embodiment) In the main body 20 of the third embodiment, as shown in FIGS. 20 to 22, four displacement portions 322 are connected to the distal end portion 21A, as in the first embodiment. As shown in FIGS. 21 and 22, the four displacement portions 322 extend toward the base end portion 21B so as to move away from the distal end portion 21A. The distance between two adjacent displacement portions 322 of the four displacement portions 322 changes significantly as the distance from the distal end portion 21A increases. When the terminal 40 is viewed from the distal end portion 21A side, the four displacement portions 322 and the distal end portion 21A appear to form a petal shape. In the third embodiment, the width of the slits in the four displacement portions 322 is variable depending on the degree to which they are opened in a direction perpendicular to the Z direction, like an umbrella. An electric device 1 may be formed using the main body 20 of the third embodiment.

[0066] In the third embodiment, as shown in FIG. 23 , the relative mover 30 has a generally C-shaped columnar shape in the XY plane. The cylindrical shaft passage 31A communicates with a notch 31B cut out of the base 31. By providing the shaft passage 31A and the notch 31B in the relative mover 30, the relative mover 30 has a generally C-shaped columnar shape in top view. The shape of the surface of the base 31 along the XY plane is C-shaped. The shape of the surface of the wedge portion 332 along the XY plane is C-shaped. In this case, too, the effects described above are achieved. Furthermore, during the manufacturing process, the relative mover 30 can be easily attached to the main body 20. Note that the electrical device 1 may be formed using the relative mover 30 of the third embodiment. The relative mover 30 having a C-shaped columnar shape may be applied to another embodiment.

[0067] (Fourth embodiment) In the main body 20 of the fourth embodiment, as shown in FIGS. 24 and 25 , two displacement portions 422 having a thickness in the Z direction are provided on the tip portion 21A. The two displacement portions 422 are lined up in the circumferential direction with a slit interposed between them. The two displacement portions 422 are integrally connected via a connecting portion 424. The two displacement portions 22 extend away from each other in a direction perpendicular to the Z direction from the tip portion 21A, and then extend in an arc clockwise direction from there. When the terminal 40 is viewed from the tip portion 21A side, the two displacement portions 22 and the tip portion 21A appear to form an S-shape. The two displacement portions 422 deform so that their arc portions move away from the shaft portion 21, thereby changing the width of the slit.

[0068] In the fourth embodiment, as shown in FIGS. 26 and 27 , the shaft portion 21 is shaped other than a cylinder in order to restrict rotation of the relative mover 30 relative to the shaft portion 21. For example, the shaft portion 21 is a prism. The shaft portion 21 extends along the Z direction. The shaft portion 21 may have any shape as long as it is a prism, and the number of vertices is not limited. The portion of the shaft portion 21 connected to the displacement portion 422 has a locally narrowed, approximately pyramidal shape to match the thickness of the displacement portion 422. Furthermore, in accordance with the main body 20, the relative mover 30 is formed with a prism-shaped shaft passage 31A through which the shaft portion 21 can pass and a groove 31C through which the connecting portion 424 connecting the two displacement portions 422 passes. The electrical device 1 may be formed using the terminal 40 of the fourth embodiment. The wedge portion 432 has a mountain-like shape that narrows as it moves away from the lower end of the base 31 in the Z direction.

[0069] (Fifth embodiment) In the fifth embodiment, the electrical device 1 is provided with a plurality of terminals 40. As shown in FIG. 28 , the shafts 21 of the plurality of terminals 40 are passed through through holes 81 formed in a plate 80 so that their positions are restricted in a direction perpendicular to the Z direction. The plate 80 is shaped to be movable in the Z direction along the shafts 21 of the terminals 40. In the fifth embodiment, the plate 80 is moved toward the rear surface opening 13B, thereby applying a load to the relative mover 30 toward the rear surface opening 13B. Even if the plate 80 is used instead of the pressing jig 70 described in the first to fourth embodiments, the same effects as those of the first to fourth embodiments can be achieved. Furthermore, instead of the pressing jig 70, a load toward the rear surface opening 13B may be applied to the relative mover 30 by a terminal of an external connector connected to the terminal 40.
