Description

[Technical field]

[0001] The present disclosure relates to a method for manufacturing a terminal block and a terminal body. [Background technology]

[0002] In general, a terminal block is used to electrically connect a first conductive member and a second conductive member. For example, a terminal block 100 in Patent Document 1 has a configuration in which a first terminal 101 and a second terminal 102 are inserted into a main housing 104 in a state in which they are electrically connected by a braided wire 103, as shown in Fig. 42.

[0003] At this time, the first terminal 101 is held by the main housing 104 via the first sub-housing 105 so as to be movable in a direction perpendicular to the penetration direction of the bolt insertion hole 101a of the first terminal 101. Also, the second terminal 102 is held by the main housing 104 via the second sub-housing 106 so as to be movable in a direction perpendicular to the penetration direction of the bolt insertion hole 102a of the second terminal 102.

[0004] As a result, even if the position of the first conductive member electrically connected to the first terminal 101 is misaligned with respect to the first terminal 101, the braided wire 103 deforms and the first terminal 101 moves with respect to the main housing 104, absorbing the misalignment between the first conductive member and the first terminal 101 and allowing them to be electrically connected to the nut 107 provided on the first sub-housing 105 in a good condition.

[0005] Furthermore, even if the position of the second conductive member electrically connected to the second terminal 102 is misaligned with respect to the second terminal 102, the braided wire 103 deforms and the second terminal 102 moves with respect to the main housing 104, absorbing the misalignment between the second conductive member and the second terminal 102 and allowing them to be satisfactorily electrically connected to the nut 108 provided on the second sub-housing 106. Such a terminal block 100 is attached to a device via a flange member 109. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2022-61147 Summary of the Invention [Problem to be solved by the invention]

[0007] Terminal block 100 of Patent Document 1 is configured to absorb misalignment of the first conductive member relative to first terminal 101 and misalignment of the second conductive member relative to second terminal 102 by deformation of braided wire 103. When braided wire 103 absorbs the mutual misalignment in this manner, a length of braided wire 103 is required, which poses a problem of terminal block 100 becoming larger.

However, the present disclosure is not limited to the following embodiments. In addition, in order to clarify the explanation, the following description and drawings are appropriately simplified. Here, in the following description, in order to clarify the explanation, a three-dimensional (XYZ) coordinate system is used. Note that the Z axis is the first axis, the Y axis is the second axis, and the X axis is the third axis.

[0022] <Embodiment 1> The configuration of the terminal block of the present embodiment will be described. Fig. 1 is a perspective view of the terminal block of the present embodiment as seen from the Z axis + side. Fig. 2 is a view of the terminal block of the present embodiment as seen from the Z axis + side. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2. Fig. 4 is an exploded perspective view of the terminal block of the present embodiment.

[0023] 1 to 4, the terminal block 1 is used to electrically connect a first conductive member 2 and a second conductive member 3. Here, the first conductive member 2 is, for example, a substantially cylindrical bus bar extending in the Z-axis direction. The second conductive member 3 is, for example, a flat bus bar substantially parallel to the XY plane and extending in the Y-axis direction.

[0024] As shown in Figures 1 to 4, the terminal block 1 includes a terminal 4 and a housing 5. As shown in Figures 3 and 4, the terminal 4 includes a terminal body 6, a first connection portion 7, and a second connection portion 8. The terminal body 6, which will be described in detail later, is a folded body obtained by folding a conductive material such as a strip-shaped metal plate extending in the Y-axis direction into a flat, approximately spiral shape.

[0025] Fig. 5 is a perspective view of the terminal body of the terminal block of the present embodiment as viewed from the Z-axis + side. Fig. 6 is a perspective view of the terminal body of the terminal block of the present embodiment as viewed from the Z-axis - side. Fig. 7 is a view of the terminal body of the terminal block of the present embodiment as viewed from the Z-axis + side.

[0026] As shown in Figures 4 to 7, the terminal body 6 includes a first flat plate portion 6a, a second flat plate portion 6b, a first connecting portion 6c, a third flat plate portion 6d, and a second connecting portion 6e. The first flat plate portion 6a is substantially parallel to the XY plane and extends in the Y-axis direction. When viewed from the Z-axis direction, the first flat plate portion 6a is, for example, substantially trapezoidal in shape with a width dimension in the X-axis direction narrowing toward the Y-axis + side.

[0027] 1 to 7, the first flat plate portion 6a is formed with a first through hole 6f penetrating the first flat plate portion 6a in the Z-axis direction. The first through hole 6f is, for example, substantially circular when viewed from the Z-axis direction. The first through hole 6f is, for example, disposed in substantially the center of the first flat plate portion 6a when viewed from the Z-axis direction.

[0028] As shown in Figures 4 to 7, the second flat plate portion 6b is generally parallel to the XY plane and extends in the Y-axis direction. The second flat plate portion 6b is generally rectangular when viewed from the Z-axis direction. The width dimension in the X-axis direction of the second flat plate portion 6b is generally equal to the width dimension in the X-axis direction of the end portion on the negative Y-axis side of the first flat plate portion 6a. The second flat plate portion 6b is overlapped with the first flat plate portion 6a in the Z-axis direction.

[0029] In detail, the second flat plate portion 6b is disposed on the negative side of the Z axis with respect to the first flat plate portion 6a, as shown in Figures 3 to 7. The negative end of the second flat plate portion 6b on the Y axis is disposed at a position substantially equal to the negative end of the first flat plate portion 6a on the Y axis when viewed from the Z axis direction. The positive end of the second flat plate portion 6b on the Y axis protrudes toward the positive side of the Y axis with respect to the positive end of the first flat plate portion 6a on the Y axis when viewed from the Z axis direction.

[0030] 3 to 6, the second flat plate portion 6b has a second through hole 6g formed therein, penetrating the second flat plate portion 6b in the Z-axis direction. The second through hole 6g has, for example, a substantially circular shape when viewed from the Z-axis direction, and is disposed so as to substantially overlap with the first through hole 6f.

[0031] A third through hole 6h penetrating the second plate portion 6b in the Z-axis direction is formed at the end portion on the Y-axis + side of the second plate portion 6b as shown in Figures 3 to 6. The third through hole 6h functions as a second connection portion 8 as described later.

[0032] Here, the end portion on the +Y-axis side of the second flat plate portion 6b may be wider in the X-axis direction than the other portions, as shown in Fig. 3. The end portion on the +Y-axis side of the second flat plate portion 6b may be in an inverted C-shape as viewed from the Y-axis direction, as shown in Figs. 4 to 6. That is, rising portions 6i may rise from both ends in the X-axis direction at the end portion on the +Y-axis side of the second flat plate portion 6b toward the +Z-axis side. The rising portions 6i may be, for example, substantially rectangular as viewed from the X-axis direction.

[0033] As shown in Figures 4 to 6, the second flat plate portion 6b has a cutout portion 6j having a shape of a substantially right-angled triangle so that the width dimension in the X-axis direction narrows toward the portion where the raised portion 6i is formed at the end portion on the Y-axis + side of the second flat plate portion 6b when viewed from the Z-axis direction; however, this may be omitted.

[0034] 3 to 6, the first connecting portion 6c connects the end portion on the negative Y-axis side of the first flat plate portion 6a and the end portion on the negative Y-axis side of the second flat plate portion 6b. The first connecting portion 6c has, for example, a flat plate shape that is substantially parallel to the XZ plane. The first connecting portion 6c has a substantially rectangular shape when viewed from the Y-axis direction.

[0035] The width dimension in the X-axis direction of the first connecting portion 6c is approximately equal to the width dimension in the X-axis direction of the end portion on the Y-axis negative side of the first flat plate portion 6a, as shown in Fig. 7. The end portion on the Z-axis positive side of the first connecting portion 6c is continuous with the end portion on the Y-axis negative side of the first flat plate portion 6a, as shown in Figs. 3 to 6, and the end portion on the Z-axis negative side of the first connecting portion 6c is continuous with the end portion on the Y-axis negative side of the second flat plate portion 6b.

[0036] As shown in Figures 3 to 6, the third flat plate portion 6d is approximately parallel to the XY plane and extends in the Y-axis direction. The third flat plate portion 6d is approximately rectangular when viewed from the Z-axis direction. The width dimension in the X-axis direction of the third flat plate portion 6d is approximately equal to the width dimension in the X-axis direction of the end portion on the Y-axis + side of the first flat plate portion 6a. The third flat plate portion 6d is disposed between the first flat plate portion 6a and the second flat plate portion 6b.

[0037] The length of the third flat plate portion 6d in the Y-axis direction is shorter than the length of the first flat plate portion 6a in the Y-axis direction, as shown in Figures 3 to 6. The end portion on the Y-axis + side of the third flat plate portion 6d is disposed at a position substantially equal to the end portion on the Y-axis + side of the first flat plate portion 6a when viewed from the Z-axis direction. The end portion on the Y-axis - side of the third flat plate portion 6d is disposed on the Y-axis - side of the first through hole 6f when viewed from the Z-axis direction.

[0038] 3 to 6, the third flat plate portion 6d is formed with a fourth through hole 6k penetrating the third flat plate portion 6d in the Z-axis direction. The fourth through hole 6k may be, for example, substantially circular when viewed from the Z-axis direction and disposed substantially concentrically with the first through hole 6f. The fourth through hole 6k has a width that allows the male screw portion 2a formed at the end portion on the Z-axis negative side of the first conductive member 2 to pass therethrough.

[0039] 3 to 6, the second connecting portion 6e connects the end portion on the Y-axis + side of the first flat plate portion 6a and the end portion on the Y-axis + side of the third flat plate portion 6d. The second connecting portion 6e has, for example, a curved shape that is convex toward the Y-axis + side when viewed from the X-axis direction.

[0040] The width dimension in the X-axis direction of the second connecting portion 6e is approximately equal to the width dimension in the X-axis direction of the end portion on the Y-axis + side of the first flat plate portion 6a, as shown in Fig. 7. The end portion on the Z-axis + side of the second connecting portion 6e is continuous with the end portion on the Y-axis + side of the first flat plate portion 6a, and the end portion on the Z-axis - side of the second connecting portion 6e is continuous with the end portion on the Y-axis - side of the third flat plate portion 6d, as shown in Figs.

[0041] The terminal body 6 has a shape in which the first flat plate portion 6a, the second flat plate portion 6b, and the third flat plate portion 6d are overlapped in the Z-axis direction and arranged substantially parallel to each other. The terminal body 6 has a shape in which the third flat plate portion 6d, the second connecting portion 6e, the first flat plate portion 6a, the first connecting portion 6c, and the second flat plate portion 6b are folded into a continuous flat spiral shape.

[0042] Here, a flow of manufacturing the terminal body 6 in the terminal block 1 of this embodiment will be described. Figures 8 to 11 are diagrams for explaining the flow of manufacturing the terminal body in the terminal block of this embodiment. First, as shown in Figure 8, a strip-shaped material 9 in which a fourth through hole 6k, a first through hole 6f, a second through hole 6g, and a third through hole 6h are formed in this order and a notch 6j is formed at a predetermined position is punched out from a conductive material such as a metal plate.

[0043] 9 and 10, the portion of the strip-shaped material 9 between the fourth through hole 6k and the first through hole 6f is folded to form the third flat plate portion 6d and the second connecting portion 6e. Then, as shown in FIG. 11, the portion of the strip-shaped material 9 between the first through hole 6f and the second through hole 6g is folded to form the first flat plate portion 6a.

[0044] Next, the portion of the strip-shaped material 9 that is bent to form the first flat portion 6a is bent toward the second through hole 6g, i.e., the third flat portion 6d is bent so as to wrap around it, thereby forming the first connecting portion 6c and the second flat portion 6b.

[0045] Thereafter, by forming a rising portion 6i at the end portion on the + side of the Y axis of the second flat plate portion 6b, the terminal body 6 can be manufactured as shown in Figures 5 to 7. By folding the strip-shaped material 9 into a flat spiral shape in this manner, the terminal body 6 can be easily manufactured. The rising portion 6i may be formed before folding the strip-shaped material 9.

[0046] 3, the first connection portion 7 is disposed on the third flat plate portion 6d which is one end portion of the terminal body 6. The first connection portion 7 is, for example, configured with a nut which is a representative example of a connection member into which the male threaded portion 2a of the first conductive member 2 is screwed. The first connection portion 7 is fixed to the surface on the Z-axis + side of the third flat plate portion 6d in a state where it is disposed substantially concentrically with the fourth through hole 6k as viewed from the Z-axis direction.

[0047] At this time, it is preferable that the end portion on the Z-axis + side of the first connection portion 7 protrudes from the first through hole 6f to the Z-axis + side while being passed through the first through hole 6f of the terminal body 6, as shown in Fig. 3. It is also preferable that a gap is formed between the outer peripheral side surface of the first connection portion 7 and the peripheral portion of the first through hole 6f of the terminal body 6 to allow displacement of the first connection portion 7 in the X-axis and Y-axis directions.

[0048] 6 and 7, the second connection portion 8 is disposed at the end portion on the Y-axis + side of the second flat plate portion 6b, which is the other end portion of the terminal body 6. The second connection portion 8 is constituted by a third through hole 6h, for example, as shown in FIG. 3, through which the bolt 10 that is passed through the through hole 3a formed in the second conductive member 3 is passed.

[0049] The housing 5 accommodates the terminal 4 as shown in Figs. 1 to 3. The housing 5 is, for example, a molded part made of an insulating material such as resin. Fig. 12 is a perspective view of the housing in the terminal block of the present embodiment as seen from the Z-axis + side. Fig. 13 is a perspective view of the housing in the terminal block of the present embodiment as seen from the Z-axis - side. Fig. 14 is a view of the housing in the terminal block of the present embodiment as seen from the Y-axis + side.

[0050] 12 to 14, the housing 5 has a hollow, generally rectangular parallelepiped shape, and the Y-axis + side and the Z-axis + side of the housing 5 are open. That is, the housing 5 includes a first side wall portion 5a, a second side wall portion 5b, a third side wall portion 5c, and a bottom portion 5d. The first side wall portion 5a has a flat plate shape generally parallel to the YZ plane, and extends in the Y-axis direction.

[0051] As shown in Figures 12 to 14, the second side wall portion 5b is disposed to face the first side wall portion 5a in the X-axis direction and is disposed on the negative side of the X-axis with respect to the first side wall portion 5a. The second side wall portion 5b has a flat plate shape substantially parallel to the YZ plane and extends in the Y-axis direction. The distance in the X-axis direction between the first side wall portion 5a and the second side wall portion 5b is, for example, substantially equal to the width dimension of the end portion on the positive side of the Y-axis of the second flat plate portion 6b of the terminal 4 as shown in Figure 1.

[0052] 12 to 14, a first protrusion 5e protruding to face each other in the X-axis direction may be formed on a corner of the first side wall 5a on the +Y-axis side and the +Z-axis side, and a corner of the second side wall 5b on the +Y-axis side and the +Z-axis side, respectively. The first protrusion 5e is, for example, substantially rectangular when viewed from the X-axis direction.

[0053] 1, the thickness in the X-axis direction of the first protrusion 5e may be approximately equal to the thickness in the X-axis direction of the rising portion 6i of the terminal 4. In addition, an inclined surface 5f may be formed on the end portion on the Z-axis + side of the first protrusion 5e, inclining toward the other first protrusion 5e as it approaches the Z-axis - side.

[0054] As shown in Figures 12 to 14, the third side wall portion 5c has a flat plate shape substantially parallel to the XZ plane and extends in the X-axis direction. The end of the third side wall portion 5c on the X-axis + side is continuous with the end of the first side wall portion 5a on the Y-axis - side, and the end of the third side wall portion 5c on the X-axis - side is continuous with the end of the second side wall portion 5b on the Y-axis - side. Therefore, when viewed from the Z-axis direction, the first side wall portion 5a, the second side wall portion 5b, and the third side wall portion 5c form a substantially C-shape.

[0055] The bottom 5d is substantially rectangular when viewed from the Z-axis direction, as shown in Figures 12 and 13. The bottom 5d is generally a flat plate shape substantially parallel to the XY plane. A first side wall 5a protrudes toward the Z-axis + side from an end of the bottom 5d on the X-axis + side, a second side wall 5b protrudes toward the Z-axis + side from an end of the bottom 5d on the X-axis - side, and a third side wall 5c protrudes toward the Z-axis + side from an end of the bottom 5d on the Y-axis - side.

[0056] The surface of the bottom 5d on the +Z-axis side is stepped as shown in Fig. 12. That is, a first portion 5g and a second portion 5h disposed on the +Z-axis side of the first portion 5g are formed on the surface of the bottom 5d on the +Z-axis side. The first portion 5g is, for example, substantially rectangular when viewed from the Z-axis direction.

[0057] In the space on the +Z-axis side of the first portion 5g, a portion on the -Y-axis side of the end portion on the +Y-axis side of the second flat plate portion 6b of the terminal 4 is disposed as shown in Fig. 1 to Fig. 3. The first portion 5g is formed with a second protruding portion 5i that protrudes toward the +Z-axis side as shown in Fig. 12. The second protruding portion 5i is, for example, in a circular ring shape as viewed from the Z-axis direction, and the outer diameter of the second protruding portion 5i is smaller than the diameter of the second through hole 6g of the terminal 4.

[0058] The second portion 5h is disposed on the +Y-axis side with respect to the first portion 5g as shown in Fig. 12, and has, for example, a substantially rectangular shape as viewed from the Z-axis direction. As shown in Figs. 1 to 3, the end portion on the +Y-axis side of the second flat plate portion 6b of the terminal 4 is disposed in the space on the +Z-axis side with respect to the second portion 5h.

[0059] 3, 12 and 13, a through hole 5j is formed in the second portion 5h, through which the bolt 10 passed through the third through hole 6h of the terminal 4 is passed. Here, the distance between the surface of the second portion 5h on the Z-axis + side and the end of the first protruding portion 5e on the Z-axis - side may be approximately equal to the height of the rising portion 6i of the terminal 4 in the Z-axis direction, as shown in FIG.

[0060] 1, with the terminal 4 accommodated inside the housing 5, the end of the second flat plate portion 6b of the terminal 4 on the Y-axis + side is placed on the surface of the second portion 5h of the bottom portion 5d of the housing 5 on the Z-axis + side, and the rising portion 6i of the terminal 4 is inserted between the second portion 5h and the first protrusion 5e. At this time, the surface of the second portion 5h of the bottom portion 5d of the housing 5 on the Z-axis + side functions as a definition surface that determines the height position of the terminal 4 inside the housing 5 in the Z-axis direction.

[0061] 3, the third through hole 6h of the terminal 4 and the through hole 5j of the housing 5 are arranged substantially concentrically when viewed from the Z-axis direction. Also, the second protrusion 5i of the housing 5 is passed through the second through hole 6g of the terminal 4 with a gap being formed between the second flat plate portion 6b of the terminal 4 and the first portion 5g of the bottom portion 5d of the housing 5 in the Z-axis direction.

[0062] At this time, a gap is formed between the terminal 4 and the inner side surface of the housing 5, allowing the portion of the second flat portion 6b of the terminal 4 on the negative side of the Y axis to deform in the X-axis direction, the Y-axis direction, and the Z-axis direction relative to the end portion on the positive side of the Y axis.

[0063] Next, a flow of assembling the terminal block 1 of this embodiment will be described. First, while accommodating the terminal 4 inside the housing 5 from the Z axis + side, the terminal 4 is pushed into the Z axis - side so that the rising portion 6i of the terminal 4 gets over the first protrusion 5e of the housing 5 to the Z axis - side. At this time, if the first protrusion 5e has an inclined surface 5f, the terminal 4 can be smoothly pushed into the Z axis - side.

[0064] Then, the end of the second flat plate portion 6b of the terminal 4 on the Y-axis + side is placed on the surface of the second portion 5h of the bottom portion 5d of the housing 5 on the Z-axis + side, while inserting the rising portion 6i of the terminal 4 between the second portion 5h and the first protrusion 5e. At the same time, while passing the second protrusion 5i of the housing 5 through the second through hole 6g of the terminal 4, the third through hole 6h of the terminal 4 and the through hole 5j of the housing 5 are arranged substantially concentrically as viewed from the Z-axis direction. This completes the assembly of the terminal block 1.

[0065] In this case, if the distance in the X-axis direction between the first side wall portion 5a and the second side wall portion 5b of the housing 5 is approximately equal to the width dimension of the Y-axis + side end of the second flat portion 6b of the terminal 4, and the distance between the Z-axis + side surface of the second portion 5h of the bottom 5d of the housing 5 and the Z-axis - side end of the first protrusion 5e is approximately equal to the Z-axis height of the raised portion 6i of the terminal 4, the housing 5 can restrain the position of the terminal 4 in the X-axis and Z-axis directions when the terminal block 1 is assembled.

[0066] Next, a flow of electrically connecting the first conductive member 2 and the second conductive member 3 to the terminal block 1 of this embodiment will be described. First, for example, the first conductive member 2 is passed through the first through hole 6f of the terminal 4 from the Z-axis + side, while the male screw portion 2a of the first conductive member 2 is screwed into the first connection portion 7 of the terminal 4. At this time, it is preferable to pass the end portion of the male screw portion 2a of the first conductive member 2 on the Z-axis + side through the fourth through hole 6k of the terminal 4.

[0067] On the other hand, for example, the second conductive member 3 is placed on the end of the second flat plate portion 6b of the terminal 4 on the Y-axis + side from the Z-axis + side, and when viewed from the Z-axis direction, the through hole 3a of the second conductive member 3, the third through hole 6h of the terminal 4, and the through hole 5j of the housing 5 are arranged approximately concentrically.

[0068] Then, from the Z-axis + side, the bolt 10 is passed through the through hole 3a of the second conductive member 3, the third through hole 6h of the terminal 4, and the through hole 5j of the housing 5, and screwed into, for example, a female thread of an electronic component (not shown). This electrically connects the first conductive member 2 and the second conductive member 3 to the terminal block 1, and also fixes the terminal block 1 to the electronic component.

[0069] Next, the deformed state of the terminal 4 in the terminal block 1 of this embodiment will be described. Fig. 15 is a view from the X-axis + side of the terminal in the terminal block of this embodiment when the terminal is deformed to the Z-axis - side. Fig. 16 is a view from the Z-axis + side of the terminal in the terminal block of this embodiment when the terminal is deformed to the X-axis - side. Fig. 17 is a view from the X-axis + side of the terminal body in the terminal block of this embodiment when the terminal is deformed to the X-axis - side. Fig. 18 is a view from the X-axis + side of the terminal in the terminal block of this embodiment when the terminal is deformed to the Y-axis + side.

[0070] 15, when a force acts on the first connection portion 7 of the terminal 4 toward the negative side of the Z axis and the first connection portion 7 is displaced toward the negative side of the Z axis, the third plate portion 6d of the terminal 4 is pushed toward the negative side of the Z axis. Accordingly, the first plate portion 6a of the terminal 4 deforms so as to tilt toward the negative side of the Z axis as it moves toward the + side of the Y axis, and the second plate portion 6b of the terminal 4 deforms so as to tilt toward the negative side of the Z axis as it moves toward the negative side of the Y axis.

[0071] In this way, the first flat plate portion 6a and the second flat plate portion 6b deform in different directions, and the mutual deformations are offset, so that the third flat plate portion 6d is maintained in a state substantially parallel to the XY plane. At this time, the third flat plate portion 6d contacts the second protrusion portion 5i of the housing 5, and it is preferable that the deformation of the third flat plate portion 6d toward the negative side of the Z axis is restricted.

[0072] 16 and 17, when a force acts on the first connection portion 7 of the terminal 4 toward the negative side of the X axis and the first connection portion 7 is displaced toward the negative side of the X axis, the third plate portion 6d of the terminal 4 is pushed toward the negative side of the X axis. Accordingly, the first plate portion 6a deforms so as to rotate counterclockwise when viewed from the positive side of the Z axis, and the second plate portion 6b deforms so as to rotate clockwise.

[0073] As shown in Figure 17, when viewed from the Y-axis + side, the first flat plate portion 6a and the second flat plate portion 6b of the terminal 4 twist clockwise as they move toward the Y-axis - side, and the third flat plate portion 6d of the terminal 4 twists counterclockwise as it moves toward the Y-axis - side.

[0074] In this manner, the first plate portion 6a, the second plate portion 6b, and the third plate portion 6d are twisted in different directions, and the mutual twists are offset, so that the third plate portion 6d is maintained in a state approximately parallel to the XY plane.

[0075] In this case, if the first flat portion 6a of the terminal 4 has a generally trapezoidal shape in which the width dimension in the X-axis direction narrows toward the Y-axis + side, when the first connecting portion 7 is displaced in the X-axis direction, the first flat portion 6a can be prevented from coming into contact with the housing 5, and the first connecting portion 7 can be displaced in the X-axis direction smoothly.

[0076] 18, when a force acts on the first connection portion 7 of the terminal 4 toward the + side of the Y axis and the first connection portion 7 is displaced toward the + side of the Y axis, the third plate portion 6d of the terminal 4 is pushed toward the + side of the Y axis. Accordingly, the third plate portion 6d of the terminal 4 is pushed toward the + side of the Y axis, and the first plate portion 6a and the second plate portion 6b are deformed so as to tilt toward the + side of the Z axis as they move toward the - side of the Y axis. Then, the third plate portion 6d of the terminal 4 is deformed so as to tilt toward the - side of the Z axis as it moves toward the - side of the Y axis.

[0077] In this way, the first and second flat plate portions 6a and 6b, and the third flat plate portion 6d deform in different directions, and the mutual deformations are offset, so that the third flat plate portion 6d is maintained in a state approximately parallel to the XY plane.

[0078] The terminal block 1 of the present embodiment is configured such that the terminal body 6 can be deformed overall in the X-axis direction, the Y-axis direction, and the Z-axis direction to absorb misalignment of the first conductive member 2 with respect to the terminal block 1. Therefore, the terminal block 1 of the present embodiment can satisfactorily connect the first conductive member 2 to the terminal block 1.

[0079] Moreover, the terminal body 6 of this embodiment has a shape in which the first flat plate portion 6a, the second flat plate portion 6b, and the third flat plate portion 6d are overlapped in the Z-axis direction and arranged substantially parallel to each other. Therefore, the deformations of the flat plate portions of the terminal body 6 are offset, and the third flat plate portion 6d can be maintained substantially parallel to the XY plane as described above, so that the first conductive member 2 can be easily connected to the first connection portion 7 of the terminal 4. In other words, the terminal block 1 of this embodiment has high connectivity of the first conductive member 2.

[0080] As described above, the terminal body 6 of this embodiment has a shape in which the third flat plate portion 6d, the second connecting portion 6e, the first flat plate portion 6a, the first connecting portion 6c, and the second flat plate portion 6b are bent into a continuous flat spiral shape. In other words, since the third flat plate portion 6d is folded back toward the inside of the terminal body 6, it is possible to absorb the positional deviation of the first conductive member 2 with respect to the terminal block 1 while suppressing the increase in size of the terminal body 6 and therefore the terminal block 1. Therefore, it is possible to contribute to the miniaturization of the terminal block 1.

[0081] Moreover, the terminal body 6 of this embodiment can be easily manufactured by folding the strip-shaped material 9 into a flat spiral shape.

[0082] <Embodiment 2> The configuration of the terminal block of this embodiment will be described. Fig. 19 is a perspective view of the terminal block of this embodiment as seen from the Z axis + side. Fig. 20 is a view of the terminal block of this embodiment as seen from the Z axis + side. Fig. 21 is a cross-sectional view taken along line XXI-XXI of Fig. 20. Fig. 22 is an exploded perspective view of the terminal block of this embodiment. Fig. 23 is a view of the terminal block of this embodiment as seen from the Z axis - side. Note that the terminal block 21 of this embodiment has a configuration substantially the same as that of the terminal block 1 of embodiment 1, and therefore repeated explanations will be omitted.

[0083] 19 to 23, the terminal block 21 includes a terminal 22 and a housing 23. The terminal 22 includes a terminal body 24, a first connection portion 25, and a second connection portion 26. The terminal body 24 is also a folded body formed by folding a conductive material such as a strip-shaped metal plate into a generally spiral shape.

[0084] Fig. 24 is a perspective view of the terminal body in the terminal block of this embodiment as viewed from the Z-axis + side. Fig. 25 is a perspective view of the terminal body in the terminal block of this embodiment as viewed from the Z-axis - side. Fig. 26 is a view of the terminal body in the terminal block of this embodiment as viewed from the Z-axis + side. Fig. 27 is a view of the terminal body in the terminal block of this embodiment as viewed from the X-axis + side.

[0085] As shown in Figures 24 to 27, the terminal body 24 includes a first flat portion 24a, a second flat portion 24b, a first connecting portion 24c, a third flat portion 24d, and a second connecting portion 24e, and further includes a first slit portion 24f and a second slit portion 24g.

[0086] As shown in Figures 24 to 26, the first slit portion 24f is formed so as to be continuous with the first flat plate portion 24a, the first connecting portion 24c, and the second flat plate portion 24b, so as to reach the Y-axis -side end of the first flat plate portion 24a via the first connecting portion 24c to the Y-axis -side end of the second flat plate portion 24b.

[0087] The first slit portion 24f, for example, as shown in Figures 24 to 26, passes through the surfaces of the first flat portion 24a, the first connecting portion 24c, and the second flat portion 24b, and is positioned on a line connecting the center of the first through hole 24h of the first flat portion 24a and the center of the second through hole 24i of the second flat portion 24b.

[0088] Here, a bent portion 24j is formed at the end portion on the Y-axis + side of the second flat plate portion 24b as shown in Figures 24 to 26. The bent portion 24j is, for example, substantially L-shaped when viewed from the Z-axis direction, and extends to the X-axis + side and further to the Y-axis + side.

[0089] A third through hole 24k is formed at the tip end (Y-axis + side) of the bent portion 24j as shown in Figures 24 to 26. Further, a fourth through hole 24l is formed at the base end (Y-axis - side) of the bent portion 24j with a gap in between in the X-axis direction.

[0090] The second slit portion 24g is formed so as to be continuous with the first flat plate portion 24a, the second connecting portion 24e, and the third flat plate portion 24d, for example, as shown in Figures 24 to 26, so as to reach the end of the third flat plate portion 24d on the Y-axis + side through the second connecting portion 24e from the first through hole 24h of the first flat plate portion 24a.

[0091] The second slit portion 24g, for example, as shown in Figures 24 to 26, passes through the surfaces of the first flat plate portion 24a, the second connecting portion 24e, and the third flat plate portion 24d, and is positioned on a line connecting the center of the first through hole 24h of the first flat plate portion 24a and the center of the fifth through hole 24m of the third flat plate portion 24d.

[0092] 21, the first connection portion 25 is composed of a bolt, which is a representative example of a connection member, screwed into a female thread portion 27a formed at an end portion on the Z-axis negative side of the first conductive member 27. The first connection portion 25 is fixed to the third flat plate portion 24d of the terminal body 24 by being sandwiched from the Z-axis direction by a crimping tool passed through the first through hole 24h and the second through hole 24i of the terminal body 24 with the shaft portion 25a of the first connection portion 25 passed through the fifth through hole 24m of the terminal body 24 from the Z-axis negative side.

[0093] 21, the second connection portion 26 is composed of a bolt, which is a representative example of a connection member, passed through a through hole 28a formed in an end portion on the Y-axis negative side of the second conductive member 28 and the third through hole 24k of the terminal body 24. The second connection portion 26 is fixed to the second flat plate portion 24b of the terminal body 24 by being clamped from the Z-axis direction by a crimping tool with the shaft portion 26a of the second connection portion 26 passed through the third through hole 24k of the terminal body 24 from the Z-axis negative side.

[0094] The housing 23 accommodates the terminals 22 as shown in Fig. 21 and Fig. 23. Fig. 28 is a perspective view of the housing in the terminal block of the present embodiment as seen from the Z-axis -side. Fig. 29 is a different perspective view of the housing in the terminal block of the present embodiment as seen from the Z-axis -side. Fig. 30 is a view of the housing in the terminal block of the present embodiment as seen from the Z-axis -side.

[0095] 28 to 30, the housing 23 is generally in the shape of a hollow rectangular parallelepiped, and the negative Z-axis side of the housing 23 is open. That is, the housing 23 includes a first side wall portion 23a, a second side wall portion 23b, a third side wall portion 23c, a fourth side wall portion 23d, and a ceiling portion 23e.

[0096] The first side wall portion 23a and the second side wall portion 23b are disposed to face each other in the X-axis direction, as shown in Figures 28 to 30. The third side wall portion 23c and the fourth side wall portion 23d are disposed to face each other in the Y-axis direction.

[0097] As shown in Figures 19 and 23, a notch 23f is formed at the end on the Z-axis negative side of the fourth side wall portion 23d arranged on the Y-axis positive side to allow the tip of the bent portion 24j of the terminal 22 to protrude to the Y-axis positive side from the housing 23. The surface on the Z-axis positive side of the notch 23f is a flat surface approximately parallel to the XY plane, for example, as shown in Figures 28 to 30.

[0098] As shown in Fig. 28 to Fig. 30, a boss 23g that is passed through the fourth through hole 24l of the terminal 22 protrudes to the negative side of the Z axis from the surface of the cutout portion 23f on the Z axis + side. As shown in Fig. 21 and Fig. 23, when the boss 23g is passed through the fourth through hole 24l of the terminal 22 and the second flat plate portion 24b of the terminal 22 is in approximate surface contact with the surface of the cutout portion 23f on the Z axis + side of the housing 23, the end of the boss 23g on the negative side of the Z axis is crushed by heat, thereby fixing the terminal 22 to the housing 23. At this time, the surface of the cutout portion 23f on the positive side of the Z axis functions as a regulating surface that determines the height position of the terminal 22 in the Z axis direction inside the housing 23.

[0099] Here, as shown in Figures 28 to 30, a first reinforcing rib 23h may be formed on the third side wall portion 23c so as to protrude from the third side wall portion 23c toward the Y-axis + side. The first reinforcing rib 23h extends in the Z-axis direction and has a substantially rectangular shape when viewed from the X-axis direction. The first reinforcing rib 23h is disposed inside the first slit portion 24f of the terminal 22, as shown in Figures 21 and 23.

[0100] Also, as shown in Figures 28 to 30, a second reinforcing rib 23i may be formed on the fourth side wall portion 23d so as to protrude from the fourth side wall portion 23d to the negative Y-axis side. The second reinforcing rib 23i extends in the Z-axis direction and has a substantially rectangular shape when viewed from the X-axis direction. The second reinforcing rib 23i is disposed inside the second slit portion 24g of the terminal 22 as shown in Figure 21.

[0101] In this manner, by forming the first reinforcing rib 23h and the second reinforcing rib 23i on the housing 23, it is possible to improve the rigidity of the housing 23. Moreover, since the first reinforcing rib 23h is disposed inside the first slit portion 24f of the terminal 22 and the second reinforcing rib 23i is disposed inside the second slit portion 24g of the terminal 22, it is possible to prevent the terminal block 21 from becoming large.

[0102] As shown in Figures 28 to 30, the fourth side wall portion 23d is formed with a fixing portion 23j that protrudes from an end portion on the X-axis negative side of the fourth side wall portion 23d toward the Y-axis positive side. The fixing portion 23j has a flat plate shape that is approximately parallel to the XY plane and is approximately rectangular when viewed from the Z-axis direction. In this case, it is preferable that a chamfered portion 23k is formed at the end portion on the Y-axis positive side of the fixing portion 23j.

[0103] Moreover, the fixing portion 23j may be reinforced by third reinforcing ribs 23l from both sides in the X-axis direction of the fixing portion 23j as shown in Figures 28 and 29. The third reinforcing rib 23l has, for example, a substantially right-angled triangular shape when viewed from the X-axis direction.

[0104] As shown in Figures 28 to 30, a first through hole 23m is formed in the fixing portion 23j. As shown in Figure 23, a collar 30 through which a bolt 29 used to fix the terminal block 21 to an electronic component is passed is disposed inside the first through hole 23m.

[0105] As shown in Figures 28 and 30, a second through hole 23n is formed in the ceiling portion 23e. As shown in Figures 19 to 21, a first conductive member 27 is passed through the second through hole 23n.

[0106] Next, a flow of assembling the terminal block 21 of this embodiment will be described. First, the portion of the terminal 22 on the negative Y-axis side with respect to the bent portion 24j is housed inside the housing 23 from the negative Z-axis side, while the tip of the bent portion 24j of the terminal 22 is caused to protrude from the cutout portion 23f of the housing 23 to the positive Y-axis side.

[0107] At this time, the boss 23g of the housing 23 is passed through the fourth through-hole 24l of the terminal 22, and the second flat plate portion 24b of the terminal 22 is brought into approximate surface contact with the Z-axis + side surface of the cutout portion 23f of the housing 23. In addition, the first reinforcing rib 23h of the housing 23 is disposed inside the first slit portion 24f of the terminal 22, and the second reinforcing rib 23i of the housing 23 is disposed inside the second slit portion 24g of the terminal 22.

[0108] Next, the negative end of the boss 23g of the housing 23 on the Z-axis side is crushed by heat, and the bent portion 24j of the terminal 22 is sandwiched between the negative end of the boss 23g of the housing 23 on the Z-axis side and the surface of the cutout portion 23f on the Z-axis + side, thereby fixing the terminal 22 to the housing 23. This completes the assembly of the terminal block 21.

[0109] Next, a description will be given of a process for fixing the terminal block 21 of this embodiment to an electronic component and electrically connecting the first conductive member 27 and the second conductive member 28 to the terminal block 21. First, the collar 30 is placed inside the first through hole 23m of the housing 23, and the bolt 29 is passed through the collar 30 and screwed into the female thread of the electronic component, thereby fixing the terminal block 21 to the electronic component.

[0110] Next, for example, while passing the first conductive member 27 through the second through hole 23n of the housing 23 and the first through hole 24h of the terminal 22 from the Z-axis + side, the shaft portion 25a of the first connection portion 25 of the terminal 22 is screwed into the female threaded portion 27a of the first conductive member 27, thereby electrically connecting the first conductive member 27 to the terminal block 21.

[0111] On the other hand, for example, from the Z-axis + side, the shaft portion 26a of the second connection portion 26 is passed through the through hole 28a of the second conductive member 28, the second conductive member 28 is placed on the tip portion of the bent portion 24j of the terminal 22, and a nut 31 is screwed onto the shaft portion 26a of the second connection portion 26 to electrically connect the second conductive member 28 to the terminal block 21. This makes it possible to fix the terminal block 21 to the electronic component and electrically connect the first conductive member 27 and the second conductive member 28 to the terminal block 21.

[0112] Like the terminal block 1 of the first embodiment, the terminal block 21 has a configuration in which the terminal body 24 is entirely deformed in the X-axis direction, the Y-axis direction, and the Z-axis direction to absorb positional deviation of the first conductive member 27 with respect to the terminal block 21. Therefore, the terminal block 21 of the present embodiment can satisfactorily connect the first conductive member 27 to the terminal block 21.

[0113] Moreover, the terminal body 24 of this embodiment also has a shape in which the first flat plate portion 24a, the second flat plate portion 24b, and the third flat plate portion 24d are overlapped in the Z-axis direction and arranged approximately parallel to each other. Therefore, deformations of the flat plate portions of the terminal body 24 are offset, the third flat plate portion 24d can be maintained approximately parallel to the XY plane, and the first conductive member 27 can be easily connected to the first connection portion 25 of the terminal 22. In other words, the terminal block 21 of this embodiment also has high connectivity of the first conductive member 27.

[0114] In addition, in the terminal body 24 of the present embodiment, the third flat plate portion 24d is also folded back toward the inside of the terminal body 24, so that it is possible to absorb the positional deviation of the first conductive member 27 with respect to the terminal block 21 while suppressing the increase in size of the terminal body 24 and therefore the terminal block 21. Therefore, it is possible to contribute to the miniaturization of the terminal block 21.

[0115] In particular, since the terminal body 24 of the present embodiment has the first slit portion 24f and the second slit portion 24g, the terminal body 24 is more easily deformed than the terminal body 6 of the first embodiment. Therefore, the terminal block 21 of the present embodiment can absorb the positional deviation of the first conductive member 27 with respect to the terminal block 21 more easily than the terminal block 1 of the first embodiment, and the first conductive member 27 can be connected to the terminal block 21 satisfactorily.

[0116] Furthermore, when the first reinforcing rib 23h and the second reinforcing rib 23i are formed on the housing 23, it is possible to improve the rigidity of the housing 23. Moreover, when the first reinforcing rib 23h is disposed inside the first slit portion 24f of the terminal 22 and the second reinforcing rib 23i is disposed inside the second slit portion 24g of the terminal 22, it is possible to prevent the terminal block 21 from becoming large.

[0117] In the present embodiment, the terminal body 24 is formed with the first slit portion 24f and the second slit portion 24g, but either one of them may be formed or the first slit portion 24f may be omitted. In addition, the first slit portion 24f is formed so as to be continuous with the first flat plate portion 24a, the first connecting portion 24c, and the second flat plate portion 24b of the terminal body 24, but it does not have to be continuous with the first slit portion 24f, and it is sufficient that the first slit portion 24f is formed at at least one of the first flat plate portion 24a, the first connecting portion 24c, and the second flat plate portion 24b.

[0118] Similarly, the second slit portion 24g is formed so as to be continuous with the first flat portion 24a, the second connecting portion 24e, and the third flat portion 24d of the terminal body 24, but it does not have to be continuous with them, and it is sufficient that the second slit portion 24g is formed in at least one of the first flat portion 24a, the second connecting portion 24e, and the third flat portion 24d.

[0119] <Embodiment 3> The configuration of the terminal block of this embodiment will be described. Fig. 31 is a perspective view of the terminal block of this embodiment as seen from the Z axis + side. Fig. 32 is a perspective view of the terminal block of this embodiment as seen from the Z axis - side. Fig. 33 is a view of the terminal block of this embodiment as seen from the Z axis + side. Fig. 34 is a cross-sectional view taken along line XXXIV-XXXIV of Fig. 33. Note that the terminal block 41 of this embodiment has a configuration substantially the same as that of the terminal block 1 of embodiment 1, and therefore repeated explanations will be omitted.

[0120] 31 to 34, the terminal block 41 includes terminals 42 on the X-axis positive side and the X-axis negative side, and a housing 43. Since the terminal 42 on the X-axis positive side and the terminal 42 on the X-axis negative side have the same configuration, the configuration of the terminal 42 on the X-axis positive side will be described as a representative example.

[0121] 34, terminal 42 has a configuration substantially similar to terminal 22 of the second embodiment, and includes a terminal body 44, a first connecting portion 45, and a second connecting portion 46. Terminal body 44 is also a folded body formed by folding a conductive material such as a strip-shaped metal plate into a substantially spiral shape.

[0122] Fig. 35 is a perspective view of the terminal body in the terminal block of this embodiment as viewed from the Z axis + side. Fig. 36 is a perspective view of the terminal body in the terminal block of this embodiment as viewed from the Z axis - side. Fig. 37 is a view of the terminal body in the terminal block of this embodiment as viewed from the Z axis + side. Fig. 38 is a view of the terminal body in the terminal block of this embodiment as viewed from the Z axis - side.

[0123] As shown in Figures 34 to 38, the terminal body 44 has a first flat plate portion 44a, a second flat plate portion 44b, a first connecting portion 44c, a third flat plate portion 44d, a second connecting portion 44e, a first slit portion 44f, and a second slit portion 44g.

[0124] As shown in Fig. 34 to Fig. 38, the first flat plate portion 44a is formed with a first through hole 44h through which a crimping jig on the Z-axis + side is passed for fixing the first conductive member 27 and the first connecting portion 45 to the third flat plate portion 44d. The second flat plate portion 44b is formed with a second through hole 44i through which a crimping jig on the Z-axis - side is passed for fixing the first connecting portion 45 to the third flat plate portion 44d. Here, the first connecting portion 45 can be formed of, for example, a bolt, similar to the first connecting portion 25 of the second embodiment.

[0125] 34 to 38, a third through hole 44j is formed in the end of the second flat plate portion 44b on the Y-axis + side, and the second connecting portion 46 is fixed with the shaft portion 46a of the second connecting portion 46 passing through the third through hole 44j. Here, the second connecting portion 46 can be formed of, for example, a bolt, similar to the second connecting portion 26 of the second embodiment.

[0126] 35 to 38, the end portion on the Y-axis + side of the second flat plate portion 44b does not have the bent portion 24j and the fourth through hole 24l as compared to the terminal body 24 of the second embodiment. Further, the end portion on the Y-axis + side of the second flat plate portion 44b is formed with a widened portion 44k that is wider in the X-axis direction than the other portions.

[0127] The widening portion 44k has a substantially triangular shape as viewed from the Z-axis direction, as shown in Fig. 37 and Fig. 38. In this case, the widening portion 44k may have an inclined portion such that the width dimension in the X-axis direction becomes wider toward the Y-axis + side as viewed from the Z-axis direction.

[0128] 37 and 38, the widened portions 44k on the X-axis + side are spaced apart in the Y-axis direction, and the widened portions 44k on the X-axis - side are spaced apart in the Y-axis direction. The widened portions 44k on the X-axis + side and the widened portions 44k on the X-axis - side are arranged to face each other in the X-axis direction.

[0129] As shown in Figures 34 to 38, a fourth through hole 44l is formed in the third flat plate portion 44d, and the first connection portion 45 is fixed with the shaft portion 45a of the first connection portion 45 passed through the fourth through hole 44l.

[0130] The first slit portion 44f is formed so as to be continuous with the first flat plate portion 44a, the first connecting portion 44c, and the second flat plate portion 44b. In this case, the first slit portion 44f may be formed to a position beyond the second through hole 44i in the second flat plate portion 44b on the Y-axis + side, as shown in Figs. 36 and 38. The second slit portion 44g is formed so as to be continuous with the first flat plate portion 44a, the second connecting portion 44e, and the third flat plate portion 44d.

[0131] 31 and 32, the housing 43 accommodates the terminals 42. The housing 43 includes a plurality of (for example, two) accommodation portions 47 arranged in the X-axis direction according to the number of the terminals 42, and a fixing portion 48. Since each accommodation portion 47 has the same shape, the accommodation portion 47 on the +X-axis side will be described as a representative example.

[0132] Fig. 39 is a perspective view of the housing of the terminal block of this embodiment as viewed from the Z axis + side. Fig. 40 is a perspective view of the housing of the terminal block of this embodiment as viewed from the Z axis - side. Fig. 41 is a perspective view of the terminals accommodated in the housing of the terminal block of this embodiment as viewed from the Z axis + side.

[0133] As shown in Figures 39 and 40, the storage section 47 includes a main body 47a, a protruding section 47b, a reinforcing rib 47c, and an insertion section 47d. The main body 47a is generally a hollow rectangular parallelepiped. The main body 47a includes a first side wall 47e, a second side wall 47f, a third side wall 47g, a ceiling section 47h, and a bottom section 47i.

[0134] The first side wall portion 47e and the second side wall portion 47f are disposed to face each other in the X-axis direction as shown in Fig. 39 to Fig. 41. The distance in the X-axis direction between the first side wall portion 47e and the second side wall portion 47f is approximately equal to the width dimension in the X-axis direction from the end of the widened portion 44k on the X-axis + side to the end of the widened portion 44k on the X-axis - side in the terminal 42. Here, the second side wall portion 47f is common to the first side wall portion 47e of the main body portion 47a adjacent on the X-axis - side.

[0135] As shown in Figures 39 and 40, the third side wall portion 47g is continuous with the end portion on the negative Y-axis side of the first side wall portion 47e and the end portion on the negative Y-axis side of the second side wall portion 47f. The ceiling portion 47h covers the negative Y-axis side portion of the space surrounded by the first side wall portion 47e, the second side wall portion 47f, and the third side wall portion 47g from the positive Z-axis side. Therefore, a continuous first opening portion 47j is formed on the positive Y-axis side of the main body portion 47a and on the positive Y-axis side of the ceiling portion 47h.

[0136] As shown in Fig. 39 to Fig. 41, the ceiling portion 47h is formed with a through hole 47k and a notch portion 47l. The shaft portion 45a of the first connection portion 45 passes through the through hole 47k. At this time, the through hole 47k, the first through hole 44h of the terminal 42, and the shaft portion 45a of the first connection portion 45 are arranged substantially concentrically as viewed from the Z-axis direction. The through hole 47k is, for example, substantially circular as viewed from the Z-axis direction, and the diameter of the through hole 47k is slightly larger than the diameter of the first conductive member 27.

[0137] 39 to 41, the cutout portion 47l is formed in the ceiling portion 47h, and extends from the through hole 47k to the Y-axis + side to reach the end of the ceiling portion 47h on the Y-axis + side. The width dimension of the cutout portion 47l in the X-axis direction is slightly wider than the diameter of the shaft portion 45a of the first connection portion 45.

[0138] 39 and 40, the bottom portion 47i spans between a corner portion on the Y-axis + side and the Z-axis - side of the first side wall portion 47e and a corner portion on the Y-axis + side and the Z-axis - side of the second side wall portion 47f. Therefore, a second opening portion 47m is formed on the Y-axis - side of the bottom portion 47i in the main body portion 47a.

[0139] 41, an end portion on the Y-axis + side of the second flat plate portion 44b of the terminal 42 is placed on the Z-axis + side surface of the bottom portion 47i. At this time, the Z-axis + side surface of the bottom portion 47i functions as a regulation surface that determines the height position of the terminal 42 in the Z-axis direction inside the main body portion 47a.

[0140] As shown in Fig. 39 to Fig. 41, the protruding portion 47b protrudes from the ceiling portion 47h to the Z-axis + side so as to surround the through hole 47k. The protruding portion 47b may be, for example, substantially annular when viewed from the Z-axis direction, and the outer peripheral side surface of the protruding portion 47b may be substantially conical in shape with a diameter decreasing toward the Z-axis + side. The protruding portion 47b is formed with a through hole 47n and a notch portion 47o.

[0141] 39 to 41, the through hole 47n is formed inside the protruding portion 47b and is continuous with the through hole 47k of the main body portion 47a in the Z-axis direction. The shaft portion 45a of the first connection portion 45 passes through the through hole 47n. The diameter of the through hole 47n is approximately equal to the diameter of the through hole 47k of the main body portion 47a.

[0142] As shown in Fig. 39 to Fig. 41, the cutout portion 47o is formed by cutting the protruding portion 47b toward the + side of the Y axis. The cutout portion 47o is continuous with the cutout portion 47l of the main body portion 47a in the Z axis direction. The width dimension of the cutout portion 47o in the X axis direction is approximately equal to the width dimension of the cutout portion 47l of the main body portion 47a in the X axis direction.

[0143] Similar to the first reinforcing rib 23h of the housing 23 of the second embodiment, the reinforcing rib 47c protrudes from the third side wall portion 47g of the main body portion 47a toward the Y-axis + side as shown in Figures 39 and 40. The reinforcing rib 47c is disposed inside the first slit portion 44f of the terminal 42 as shown in Figures 32 and 34.

[0144] In this case, it is preferable that the reinforcing rib 47c has a horizontal portion 47p that protrudes from an end portion of the reinforcing rib 47c on the negative side of the Z axis toward the positive side of the Y axis, as shown in Figures 39 and 40. The horizontal portion 47p is disposed on the negative side of the Z axis with respect to the end portion of the third flat plate portion 44d of the terminal 42 on the negative side of the Y axis, as shown in Figures 32 and 34.

[0145] The horizontal portion 47p comes into contact with the Y-axis negative end of the third flat plate portion 44d of the terminal 42 when the Y-axis negative end of the third flat plate portion 44d is displaced a predetermined amount toward the Z-axis negative side, thereby making it possible to limit the amount of displacement of the Y-axis negative end of the third flat plate portion 44d.

[0146] The insertion portion 47d is used when inserting the terminal 22 into the inside of the main body portion 47a, as described later. As shown in Fig. 39 to Fig. 41, the insertion portion 47d is formed by a first opening portion 47j of the main body portion 47a, a notch portion 47l of the main body portion 47a, and a notch portion 47o of the protrusion portion 47b.

[0147] As shown in Fig. 39 to Fig. 41, the fixing portion 48 has substantially the same shape as the fixing portion 23j of the housing 23 of the second embodiment, and for example, protrudes to the X-axis - side from the accommodation portion 47 on the X-axis - side. A through hole 48a is formed in the fixing portion 48. A collar 50 is disposed inside the through hole 48a, as shown in Fig. 32, through which a bolt 49 used to fix the terminal block 41 to an electronic component is passed.

[0148] Next, a flow of assembling the terminal block 41 of this embodiment will be described. First, the terminal 42 is inserted into the inside of the main body 47a from the first opening 47j of the main body 47a in the insertion portion 47d of the housing 43 toward the negative side of the Y axis.

[0149] Then, the shaft portion 45a of the first connection portion 45 of the terminal 42 is passed through the cutout portion 47l of the main body portion 47a and the cutout portion 47o of the protrusion portion 47b in the insertion portion 47d of the housing 43, and further, the shaft portion 45a of the first connection portion 45 of the terminal 42 is passed through the through hole 47k of the main body portion 47a and the through hole 47n of the protrusion portion 47b.

[0150] At this time, when viewed from the Z-axis direction, the shaft portion 45a of the first connection portion 45 of the terminal 42, the first through hole 44h of the terminal 42, the through hole 47k of the main body portion 47a, and the through hole 47n of the protrusion portion 47b are arranged approximately concentrically.

[0151] At the same time, the Y-axis + side end of the second flat plate portion 44b of the terminal 42 is placed on the Z-axis + side surface of the bottom portion 47i of the main body portion 47a. At this time, the distance in the X-axis direction between the first side wall portion 47e and the second side wall portion 47f of the main body portion 47a in the housing 43 is approximately equal to the width dimension in the X-axis direction from the X-axis + side end of the X-axis + side widened portion 44k of the terminal 42 to the X-axis - side end of the X-axis - side widened portion 44k.

[0152] Therefore, the end portion on the Y-axis + side of the second flat plate portion 44b of the terminal 42 is sandwiched and held between the first side wall portion 47e and the second side wall portion 47f of the main body portion 47a of the housing 43, and as a result, the terminal 42 can be restrained by the housing 43. This completes the assembly of the terminal block 41.

[0153] Next, a description will be given of a process for fixing the terminal block 41 of this embodiment to an electronic component and electrically connecting the first conductive member 27 and the second conductive member 28 to the terminal block 41. First, a collar 50 is placed inside the through hole 48a of the fixing portion 48 of the housing 43, and a bolt 49 is passed through the collar 50 and screwed into the female thread of the electronic component, thereby fixing the terminal block 41 to the electronic component.

[0154] Next, for example, the first conductive member 27 is passed from the Z-axis + side through the through hole 47k of the main body 47a of the housing 43 and the through hole 47n of the protrusion 47b, and through the first through hole 44h of the terminal 42, while the shaft portion 45a of the first connection portion 45 of the terminal 42 is screwed into the female threaded portion 27a of the first conductive member 27, thereby electrically connecting the first conductive member 27 to the terminal block 41.

[0155] At this time, the first conductive member 27 is surrounded by the protruding portion 47b of the housing portion 47, and the first conductive member 27 comes into contact with the protruding portion 47b when the first conductive member 27 vibrates. This makes it possible to limit the vibration of the first conductive member 27.

[0156] On the other hand, for example, the second conductive member 28 is placed on the end portion on the Y-axis + side of the second flat plate portion 44b of the terminal 42 by passing the shaft portion 46a of the second connection portion 46 through the through hole 28a of the second conductive member 28 from the Z-axis + side via the first opening 47j of the main body portion 47a in the insertion portion 47d of the housing 43.

[0157] Then, the nut 51 is screwed onto the shaft portion 46a of the second connection portion 46 to electrically connect the second conductive member 28 to the terminal block 41. This makes it possible to fix the terminal block 41 to the electronic component and electrically connect the first conductive member 27 and the second conductive member 28 to the terminal block 41.

[0158] Like the terminal block 1 of the first embodiment, the terminal block 41 has a configuration in which the terminal body 44 is entirely deformed in the X-axis, Y-axis, and Z-axis directions to absorb positional deviation of the first conductive member 27 with respect to the terminal block 41. Therefore, the terminal block 41 of the present embodiment can satisfactorily connect the first conductive member 27 to the terminal block 41.

[0159] Moreover, the terminal body 44 of this embodiment also has a shape in which the first flat plate portion 44a, the second flat plate portion 44b, and the third flat plate portion 44d are overlapped in the Z-axis direction and arranged substantially parallel to each other. Therefore, deformations of the flat plate portions of the terminal body 44 are offset, the third flat plate portion 44d can be maintained substantially parallel to the XY plane, and the first conductive member 27 can be easily connected to the first connection portion 45 of the terminal 42. In other words, the terminal block 41 of this embodiment also has high connectivity of the first conductive member 27.

[0160] Moreover, in the terminal body 44 of the present embodiment, the third flat plate portion 44d is also folded back toward the inside of the terminal body 44, so that it is possible to absorb the positional deviation of the first conductive member 27 with respect to the terminal block 41 while suppressing the increase in size of the terminal body 44 and therefore the terminal block 41. This can contribute to the miniaturization of the terminal block 41.

[0161] In particular, since the housing 43 of the terminal block 41 of this embodiment is formed with the protruding portion 47b, when the first conductive member 27 deflects, the first conductive member 27 comes into contact with the protruding portion 47b, thereby limiting the deflection of the first conductive member 27. Moreover, since the reinforcing rib 47c of the housing 43 of the terminal block 41 is formed with the horizontal portion 47p, when the end portion on the Y-axis negative side of the third flat plate portion 44d of the terminal 42 is displaced to the Z-axis negative side by a predetermined amount of displacement, the horizontal portion 47p comes into contact with the end portion on the Y-axis negative side of the third flat plate portion 44d, thereby limiting the amount of displacement of the end portion on the Y-axis negative side of the third flat plate portion 44d.

[0162] In addition, since the housing 43 of the terminal block 41 of the present embodiment is formed with the insertion portion 47d, the terminal 42 can be easily inserted into the accommodating portion 47 of the housing 43 toward the Y-axis negative side. Therefore, the assembly of the terminal block 41 is easy.

[0163] The present disclosure is not limited to the above-described embodiment, and can be modified as appropriate without departing from the spirit and scope of the present disclosure.

[0164] The numbers of terminals 4, 22, 42 of the terminal blocks 1, 21, 41 in the above-described embodiments are merely examples and can be changed as appropriate. In this case, the shape of the housing can be changed as appropriate so as to accommodate the terminals 4, 22, 42 depending on the numbers of the terminals 4, 22, 42.

[0165] Although the terminal blocks 1, 21, and 41 in the above-described embodiments are fixed to an electronic component, the type of fixed component to which the terminal block is fixed is not important. The number, arrangement, or shape of the fixing parts of the housing is not important as long as the terminal block can be fixed to the fixed component. Moreover, the means for fixing the terminal block to the fixed component is also not important.

[0166] The first conductive members 2, 27 and the second conductive members 3, 28 electrically connected to the terminal blocks 1, 21, 41 in the above-described embodiments are merely examples, and may have any shape that allows them to be electrically connected to the terminals 4, 22, 42. In addition, there is no restriction on the means by which the first conductive members and the second conductive members are electrically connected to the terminals.

[0167] The shapes of the terminal bodies 6, 24, 44 and the housings 5, 23, 43 of the terminal blocks 1, 21, 41 in the above embodiments are merely examples, and in short, it is sufficient that the third flat plate portion, the second connecting portion, the first flat plate portion, the first connecting portion and the second flat plate portion are folded into a flat spiral shape, and the first conductive member is provided with a terminal that can be electrically connected to the third flat plate portion through a through hole formed in the first flat plate portion.
