[0007] [Problem to be Solved by the Present Disclosure] When connecting another bus bar to the above-mentioned bus bar, a special method such as ultrasonic welding, TOX (registered trademark) caulking, or laser joining is generally used.

[0008] However, such a method requires a special device, and thus has problems such as an increase in operating cost. However, in the power supply device of Patent Document 1, such a problem is not considered and cannot be solved.

[0009] Therefore, an object is to provide a connecting component which can connect conductive plates to each other more simply and at a lower cost.

[0010] [Effects of the Present Disclosure] According to the present disclosure, it is possible to provide a connection component that can connect conductive plates to each other more simply and at low cost.

[0011] [Description of Embodiments of the Invention] First, embodiments of the present disclosure will be described by way of example. In addition, at least a portion of the embodiments described below may be arbitrarily combined.

[0012] (1) A connection component according to an embodiment of the present disclosure connects a plurality of stacked conductive plates, and includes a cylindrical frame into which the conductive plates are inserted, and a protruding portion that protrudes toward the inside of the cylindrical frame.

[0013] In this embodiment, the outer main surfaces of the plurality of conductive plates inserted into the cylindrical frame and stacked are pressed by the protruding portion, so that the plurality of conductive plates are electrically connected.

[0014] (2) In the connection member according to the embodiment of the present disclosure, the protruding portion includes a first bent plate portion that is continuously provided at an edge of one wall of the cylindrical frame and is bent toward the inside of the cylindrical frame.

[0015] In this embodiment, when the stacked plurality of conductive plates are inserted into the cylindrical frame, the first curved plate portion is deformed, and the outer main surfaces of the plurality of conductive plates are pressed by the deformed first curved plate portion, so that the plurality of conductive plates are electrically connected.

[0016] (3) In the connection member according to the embodiment of the present disclosure, the protruding portion includes a second curved plate portion that is continuously provided at an edge of the other wall facing the first wall and is bent toward the inside of the cylindrical frame, and the first curved plate portion and the second curved plate portion face each other.

[0017] In this embodiment, when the overlapping plurality of conductive plates are inserted into the cylindrical frame, the first curved plate portion and the second curved plate portion are deformed, and the two outer main surfaces of the plurality of conductive plates are pressed in the overlapping direction by the deformed first curved plate portion and the second curved plate portion, respectively. Therefore, the plurality of conductive plates are electrically connected.

[0018] (4) In the connection member according to the embodiment of the present disclosure, the end portion of the first curved plate portion and the end portion of the second curved plate portion are separated from the inner surface of the cylindrical frame.

[0019] In this embodiment, the end of the first curved plate portion and the end of the second curved plate portion are separated from the inner surface of the cylindrical frame, so when the overlapping plurality of conductive plates are inserted into the cylindrical frame, the first curved plate portion and the second curved plate portion are easily deformed. The deformed first curved plate portion and the second curved plate portion respectively press the two outer main surfaces of the plurality of conductive plates in the overlapping direction. Therefore, the plurality of conductive plates are electrically connected.

[0020] (5) In the connection member according to the embodiment of the present disclosure, the end portion of the first curved plate portion and the end portion of the second curved plate portion are bent toward the one wall and the other wall, respectively.

[0021] In this embodiment, the end of the first curved plate portion and the end of the second curved plate portion are bent toward the one wall and the other wall, respectively. Therefore, when the overlapping plurality of conductive plates are inserted into the cylindrical frame, the first curved plate portion and the second curved plate portion are deformed and their respective ends abut against the one wall and the other wall, and the restoring force to restore to the original shape becomes larger. Therefore, the deformed first curved plate portion and the second curved plate portion more strongly press the two outer main surfaces of the plurality of conductive plates in the overlapping direction.

[0022] (6) In the connection member according to the embodiment of the present disclosure, the protrusion includes an embossed portion that partially raises one wall of the cylindrical frame.

[0023] In this embodiment, when the stacked plurality of conductive plates are inserted into the cylindrical frame, the embossed portion is deformed, and the outer main surfaces of the plurality of conductive plates are pressed by the deformed embossed portion, so that the plurality of conductive plates are electrically connected.

[0024] (7) The connection member according to the embodiment of the present disclosure includes a pair of semi-cylindrical portions which are provided on the side facing the one wall and are arranged side by side in the radial direction.

[0025] In this embodiment, when the overlapping plurality of conductive plates are inserted into the cylindrical frame, in addition to the embossed portion, the pair of semi-cylindrical portions are also deformed, and the two outer main surfaces of the plurality of conductive plates are pressed in the overlapping direction by the deformed embossed portion and the pair of semi-cylindrical portions, respectively. Therefore, the plurality of conductive plates are electrically connected.

[0026] (8) In the connection member according to the embodiment of the present disclosure, each semi-cylindrical portion is convexly curved toward the outside of the cylindrical frame.

[0027] In this embodiment, when the overlapping plurality of conductive plates are inserted into the cylindrical frame, the embossed portion and the pair of semi-cylindrical portions are deformed, and the circumferential ends of each semi-cylindrical portion and the protruding ends of the embossed portion are respectively in contact with the two outer main surfaces of the plurality of conductive plates. In this state, the deformed embossed portion and the pair of semi-cylindrical portions respectively press the two outer main surfaces of the plurality of conductive plates in the overlapping direction. Therefore, the plurality of conductive plates are electrically connected.

[0028] (9) In the connection member according to the embodiment of the present disclosure, the pair of semi-cylindrical portions are disconnected from each other.

[0029] In this embodiment, since the pair of semi-cylindrical parts are disconnected from each other, the degree of freedom of deformation of each semi-cylindrical part is increased. That is, when the plurality of conductive plates are deformed by being inserted into the cylindrical frame, each semi-cylindrical part can be deformed freely according to the concavo-convexity of the outer main surface of the conductive plate. Therefore, the plurality of conductive plates can be connected more reliably.

[0030] [Details of the Embodiment of the Invention] Hereinafter, the connection components according to the embodiment of the present disclosure will be described with reference to the accompanying drawings. It should be noted that the present invention is not limited to these examples, but is indicated by the claims, and is intended to include all changes within the meaning and scope equivalent to the claims.

[0031] (Embodiment 1) Hereinafter, an embodiment will be described based on the drawings. Figure 1 is a perspective view showing the connecting member 100 according to the first embodiment from one side. Figure 2 is a perspective view showing the connecting member 100 according to the first embodiment from the other side. Figure 3 yes Figure 1 Cross-sectional view along line III-III.

[0032] The connection member 100 according to Embodiment 1 electrically connects a plurality of conductive plates. For example, the connection member 100 electrically connects a plurality of bus bars by sandwiching a plurality of overlapping bus bars from opposite outer sides so that the main surfaces of the bus bars contact each other.

[0033] The connection member 100 includes a cylindrical frame 30 into which a plurality of conductive plates to be connected are inserted, and a first curved plate portion 10 (protruding portion) and a second curved plate portion 20 (protruding portion) protruding into the cylindrical frame 30 to sandwich the plurality of conductive plates.

[0034] The cylindrical frame 30 is in the shape of a square cylinder with a rectangular cross section and is made of a material with excellent elasticity such as steel. The first facing wall 31 and the second facing wall 33 facing each other are respectively provided with a first curved plate portion 10 and a second curved plate portion 20. The first facing wall 31 and the second facing wall 33 are rectangular, and the facing long edges are connected to each other by side walls 32 and 34. The first facing wall 31, the second facing wall 33, and the side walls 32 and 34 are formed integrally. That is, the cylindrical frame 30 is composed of a sheet material and is manufactured by bending the sheet material.

[0035] In addition, the end portion 341 of the side wall 34 close to the first facing wall 31 is bent toward the first facing wall 31 to cover the outer side of the first facing wall 31. Therefore, the first facing wall 31 is prevented from opening in a direction away from the second facing wall 33.

[0036] In the length direction, the first curved plate portion 10 and the second curved plate portion 20 are continuously provided at one end of the cylindrical frame 30. Specifically, the first curved plate portion 10 is continuously provided at a short edge in the length direction of the first facing wall 31, and the second curved plate portion 20 is continuously provided at a short edge in the length direction of the second facing wall 33.

[0037] The first curved plate portion 10 is made of a rectangular plate made of the same material as the cylindrical frame 30. The edge of one end side of the first curved plate portion 10 in the longitudinal direction is continuously provided on the one short edge of the first opposing wall 31, and is bent toward the inner side of the cylindrical frame 30. That is, the first curved plate portion 10 is bent toward the inner side of the cylindrical frame 30 at one end 11. In addition, the other end 12 of the other end side of the first curved plate portion 10 in the longitudinal direction is bent toward the first opposing wall 31. At this time, the edge of the other end 12 is arranged separately from the first opposing wall 31 (refer to Figure 3 ). The first curved plate portion 10 protrudes from the first opposing wall 31 toward the inner side of the cylindrical frame 30. For example, the curvature radius of the other end portion 12 is larger than the curvature radius of the one end portion 11.

[0038] The second curved plate portion 20 is formed of a rectangular plate made of the same material as the cylindrical frame 30, similarly to the first curved plate portion 10. The edge of one end side of the second curved plate portion 20 in the longitudinal direction is continuously provided on the one short edge of the second opposing wall 33, and is bent toward the inner side of the cylindrical frame 30. That is, the second curved plate portion 20 is bent toward the inner side of the cylindrical frame 30 at one end 21. In addition, the other end 22 of the other end side of the second curved plate portion 20 in the longitudinal direction is bent toward the second opposing wall 33. At this time, the edge of the other end 22 is arranged separately from the second opposing wall 33 (refer to Figure 3 That is, the second curved plate portion 20 is an inverted shape of the first curved plate portion 10, and the second curved plate portion 20 protrudes from the second opposing wall 33 toward the inside of the cylindrical frame 30. For example, the curvature radius of the other end portion 22 is larger than the curvature radius of the one end portion 21.

[0039] like Figure 3 As shown, the first curved plate portion 10 and the second curved plate portion 20 face each other, and the interval between one end 11 of the first curved plate portion 10 and one end 21 of the second curved plate portion 20 is wider than the interval between the other end 12 of the first curved plate portion 10 and the other end 22 of the second curved plate portion 20. That is, in the middle portion in the length direction, the interval between the first curved plate portion 10 and the second curved plate portion 20 becomes narrower as it moves from one end to the other end of the cylindrical frame 30. The cylindrical frame 30 and the first curved plate portion 10 and the second curved plate portion 20 are integrally formed.

[0040] Figure 4 1 is an explanatory diagram showing a state in which the connection member 100 according to the first embodiment electrically connects two overlapping bus bars 200 and 300 . Figure 5 yes Figure 4 The bus bars 200 and 300 are made of conductive plates such as copper, and their main surfaces are rectangular with the same size, but the bus bar 200 is thinner than the bus bar 300.

[0041] The user presses the bus bars 200 and 300 into the connecting member 100 (the cylindrical frame 30) from one end side of the cylindrical frame 30, that is, from between the one end 11 of the first curved plate portion 10 and the one end 21 of the second curved plate portion 20, while overlapping the bus bars 200 and 300 with their main surfaces in contact with each other (see Figure 4 ). As a result, the busbars 200 and 300 are interposed between the first curved plate portion 10 and the second curved plate portion 20 in an overlapping state. At this time, the first curved plate portion 10 and the second curved plate portion 20 are deformed toward the first opposing wall 31 and the second opposing wall 33, respectively, so a restoring force to restore the original shape acts. Therefore, the first curved plate portion 10 and the second curved plate portion 20 press and clamp the outer main surfaces of the overlapping busbars 200 and 300 from both sides toward each other.

[0042] That is, the flat center portion of the first curved plate portion 10 abuts against the outer main surface of the bus bar 200 to apply force to the bus bar 200 toward the bus bar 300, and the flat center portion of the second curved plate portion 20 abuts against the outer main surface of the bus bar 300 to apply force to the bus bar 300 toward the bus bar 200 (see Figure 5 ). As a result, the inner main surfaces of the bus bars 200 and 300 are in contact with each other, so that the bus bars 200 and 300 are electrically connected.

[0043] In addition, if Figure 5 As shown, when the busbars 200 and 300 are interposed between the first bent plate portion 10 and the second bent plate portion 20, the edge of the other end portion 12 of the separated first bent plate portion 10 abuts against the first facing wall 31, and the edge of the other end portion 22 of the separated second bent plate portion 20 abuts against the second facing wall 33. In addition, as described above, the other end portion 12 of the first bent plate portion 10 is bent toward the first facing wall 31, and the other end portion 22 of the second bent plate portion 20 is bent toward the second facing wall 33. Therefore, the other end portion 12 of the first bent plate portion 10 and the other end portion 22 of the second bent plate portion 20 further act stress (restoring force) outward in the radial direction. That is, the other end portion 12 of the first bent plate portion 10 and the other end portion 22 of the second bent plate portion 20 act as a spring. By the restoring force of the other end portion 12 and the other end portion 22, the inner main surfaces of the busbars 200 and 300 are in contact with each other more firmly.

[0044] In addition, the bus bars 200 and 300 may be provided with engaging portions and engaged portions corresponding to the engaging portions, respectively, so that when the user overlaps the bus bars 200 and 300 and presses them into the connecting component 100 (the cylindrical frame 30) from one end side of the cylindrical frame 30, the positional displacement of the bus bars 200 and 300 will not occur.

[0045] Figure 6 1 is an illustrative diagram illustrating an engaging portion 201 formed on the bus bar 200 and an engaged portion 301 formed on the bus bar 300 . Specifically, the relatively thin bus bar 200 is subjected to embossing at the long side end, a concave portion is formed on the outer main surface of the bus bar 200, and the engaging portion 201, which is a convex portion, is formed on the inner main surface on the opposite side. In addition, the relatively thick bus bar 300 is subjected to embossing at a position facing the engaging portion 201 of the bus bar 200 on the inner main surface, forming the engaged portion 301, which is a concave portion. The engaging portion 201 and the engaged portion 301 are formed to have a semicircular cross-section, and the curvature radius of the engaging portion 201 (convex) is larger than the curvature radius of the engaged portion 301 (concave).

[0046] Therefore, when the bus bars 200 and 300 overlap (see Figure 6), the engaging portion 201 and the engaged portion 301 are engaged, and in the state where the engaging portion 201 and the engaged portion 301 are engaged, the bus bars 200 and 300 are pressed into the cylindrical frame 30 (refer to Figure 4 ). Therefore, the connection between the bus bar 200 (engaging portion 201 ) and the bus bar 300 (engaged portion 301 ) can be ensured, and positional deviation when the bus bars 200 , 300 are pressed into the cylindrical frame 30 can be suppressed.

[0047] In the above description, the engaging portion 201 and the engaged portion 301 are formed at the ends of the long sides of the bus bars 200 and 300 , but the present invention is not limited thereto and may be formed at other locations such as the central portion of the bus bars 200 and 300 .

[0048] As described above, in the connection component 100 of the first embodiment, the conductive plates can be electrically connected to each other simply by overlapping the plurality of conductive plates and pressing the plurality of conductive plates into the connection component 100 (cylindrical frame 30). Therefore, the connection component 100 of the first embodiment does not use a special device, etc., and can electrically connect the conductive plates to each other more simply and at a low cost.

[0049] In the connection member 100 of the first embodiment, the interval between the first curved plate portion 10 and the second curved plate portion 20 is narrowed as the distance from one end to the other end of the cylindrical frame 30 in the length direction is increased. Therefore, the plurality of overlapping conductive plates can be easily inserted into the cylindrical frame 30, and the plurality of conductive plates can be reliably clamped (connected).

[0050] Furthermore, in the above, the case where the connecting member 100 of the first embodiment includes both the first curved plate portion 10 and the second curved plate portion 20 is described as an example, but the present invention is not limited thereto, and either one of the two may be omitted.

[0051] In addition, the above description takes the case where the plurality of conductive plates are of a size that can be pressed into the connecting member 100 (cylindrical frame 30) as an example, but the present invention is not limited thereto. In the case where the plurality of conductive plates are of a size that cannot be pressed into the cylindrical frame 30, protrusions may be formed on each conductive plate, and the overlapping protrusions may be pressed into the cylindrical frame 30.

[0052] (Implementation method 2) Figure 7 is a perspective view showing the connecting member 100 according to the second embodiment from one side. Figure 8 is a perspective view showing the connecting member 100 according to the second embodiment from the other side. Fig. 9 yes Figure 7 The connection member 100 according to the second embodiment electrically connects the plurality of conductive plates by, for example, sandwiching the plurality of conductive plates stacked on top of each other from opposite outer sides so that the main surfaces of the conductive plates abut against each other.

[0053] The connecting component 100 comprises: a cylindrical frame 30A, inside which a plurality of conductive plates to be connected are inserted; an embossed portion 20A (protrusion) protruding toward the inside of the cylindrical frame 30A and used for clamping the plurality of conductive plates; and a semi-cylindrical portion 10A, arranged opposite to the embossed portion 20A and used for clamping the plurality of conductive plates.

[0054] The cylindrical frame 30A is roughly cylindrical and is made of a material with excellent elasticity such as steel. The cylindrical frame 30A has a flat plate portion 33A in the shape of a flat rectangular plate, and an embossed portion 20A is formed in the central portion of the flat plate portion 33A. A pair of semi-cylindrical portions 10A are provided at a position facing the flat plate portion 33A, and the flat plate portion 33A and the pair of semi-cylindrical portions 10A are connected by side walls 32 and 34. The flat plate portion 33A, the side walls 32 and 34, and the pair of semi-cylindrical portions 10A are formed integrally. That is, the cylindrical frame 30A is composed of a sheet material, and is manufactured by bending and embossing the sheet material.

[0055] Fig.10 3D is a perspective view of the connecting component 100 showing the outer side of the flat plate portion 33A. As described above, an embossed portion 20A is formed in the central portion of the flat plate portion 33A so that the flat plate portion 33A is partially raised by embossing. The embossed portion 20A protrudes from the flat plate portion 33A to the inner side of the cylindrical frame 30A. That is, the embossed portion 20A forms a concave portion on the outer side of the flat plate portion 33A and a convex portion on the inner side of the flat plate portion 33A. The embossed portion 20A is roughly rectangular in a cross section along the surface direction of the flat plate portion 33A, and the end face of the protruding front end is a flat rectangular face.

[0056] The side walls 32 and 34 are respectively provided continuously at the two long edges of the flat plate portion 33A. The side walls 32 and 34 are of the same size and are in the shape of long strips extending along the long edges of the flat plate portion 33A, and are vertically provided relative to the flat plate portion 33A. That is, the two long edges of the flat plate portion 33A are respectively provided continuously with one long edge of the side walls 32 and 34.

[0057] As described above, a pair of semi-cylindrical portions 10A are provided at positions facing the flat plate portion 33A. Specifically, the semi-cylindrical portions 10A are provided continuously at the other long edges of the side walls 32 and 34. Each semi-cylindrical portion 10A is formed into a semi-cylindrical shape extending along the length direction of the flat plate portion 33A, and the pair of semi-cylindrical portions 10A are provided side by side in a manner adjacent to each other in the radial direction.

[0058] One of the two radially opposing ends of each semi-cylindrical portion 10A is provided continuously with the other long edge of the side walls 32, 34. In addition, the pair of semi-cylindrical portions 10A are disconnected from each other. That is, in the pair of semi-cylindrical portions 10A, one of the circumferential ends is provided continuously with the side walls 32, 34 as described above, and the other circumferential ends are not connected to each other but are arranged adjacent to each other in this state.

[0059] The pair of semi-cylindrical portions 10A have the same curvature radius and are convexly curved toward the outside of the cylindrical frame 30A. That is, the circumferential end of the other of the pair of semi-cylindrical portions 10A extends toward the embossed portion 20A and faces the embossed portion 20A.

[0060] Fig.11 1 is an explanatory diagram showing a state in which the connection member 100 according to the second embodiment electrically connects two overlapping bus bars 200 and 300 . Fig.12 yes Fig.11 The bus bars 200 and 300 are made of a conductive plate material such as copper, and their main surfaces are rectangular with the same size, but the bus bar 200 is thinner than the bus bar 300 .

[0061] The user presses the bus bars 200 and 300 into the connection member 100 (the cylindrical frame 30A) from one end side of the cylindrical frame 30A while overlapping the bus bars 200 and 300 with their main surfaces in contact with each other (see Fig.11 ). As a result, the busbars 200 and 300 are placed in an overlapping state between a pair of semi-cylindrical portions 10A (the circumferential end of the other side) and the embossed portion 20A. At this time, each semi-cylindrical portion 10A is deformed toward the outside of the cylindrical frame 30A in the direction facing each other (hereinafter referred to as the facing direction) with the embossed portion 20A, and the embossed portion 20A is subjected to a pressing force toward the outside of the cylindrical frame 30A in the facing direction. In contrast, a restoring force to restore the original shape acts on each curved semi-cylindrical portion 10A, and a reaction force toward the inside of the cylindrical frame 30A is generated in the convexly formed embossed portion 20A. Therefore, a pair of semi-cylindrical portions 10A and the embossed portion 20A press and clamp the outer main surfaces of the overlapping busbars 200 and 300 from both sides toward each other.

[0062] That is, the other circumferential end of each semi-cylindrical portion 10A abuts against the outer main surface of the bus bar 200 to apply force to the bus bar 200 toward the bus bar 300, and the flat front end surface of the embossed portion 20A abuts against the outer main surface of the bus bar 300 to apply force to the bus bar 300 toward the bus bar 200 (see Fig.12 ). As a result, the inner main surfaces of the bus bars 200 and 300 are in contact with each other, so that the bus bars 200 and 300 are electrically connected.

[0063] In addition, similar to the first embodiment, an engaging portion and an engaged portion corresponding to the engaging portion may be provided on the bus bars 200 and 300, respectively, so that when the user overlaps the bus bars 200 and 300 and presses them into the connecting component 100 (cylindrical frame 30A) from one end side of the cylindrical frame 30A, the bus bars 200 and 300 will not be misaligned.

[0064] As described above, in the connection component 100 of the second embodiment, the conductive plates can be electrically connected to each other simply by overlapping the plurality of conductive plates and pressing the plurality of conductive plates into the connection component 100 (cylindrical frame 30A). Therefore, the connection component 100 of the second embodiment does not use a special device, etc., and can electrically connect the conductive plates to each other more simply and at a low cost.

[0065] In addition, since the connection member 100 of the second embodiment uses the cylindrical frame 30A with both sides open in the longitudinal direction, a plurality of conductive plates can be inserted into the cylindrical frame 30A from both ends in the longitudinal direction. Therefore, the degree of freedom in operation can be improved.

[0066] In addition, in the connection component 100 of the second embodiment, a pair of semi-cylindrical parts 10A are disconnected from each other. Therefore, the degree of freedom of deformation of each semi-cylindrical part 10A in the facing direction is increased. That is, one semi-cylindrical part 10A can be deformed without being affected by the other semi-cylindrical part 10A. Therefore, even if the surface of the conductive plate of the object is uneven and there is a local convex part, each semi-cylindrical part 10A deforms independently to increase the contact points, and the conductive plates can be properly electrically connected to each other.

[0067] In the above, in the connection component 100 of the second embodiment, the case where one embossed portion 20A is formed on the flat plate portion 33A is described as an example, but the present invention is not limited to this, and a structure in which a plurality of smaller embossed portions 20A are formed on the flat plate portion 33A may also be adopted.

[0068] In the above, in the connection member 100 of the second embodiment, the pair of semi-cylindrical portions 10A are described as being disconnected from each other, but the present invention is not limited thereto. The pair of semi-cylindrical portions 10A may be connected to each other, that is, the other circumferential ends may be connected to each other.

[0069] In addition, although the above description takes the case where the pair of semi-cylindrical portions 10A are convexly curved toward the outside of the cylindrical frame 30A as an example, the present invention is not limited thereto. The pair of semi-cylindrical portions 10A may be configured to be convexly curved toward the inside of the cylindrical frame 30A.

[0070] The same parts as those in Embodiment 1 are denoted by the same reference numerals and detailed description thereof will be omitted.

[0071] The technical features (constituent elements) described in Embodiment 1 to Embodiment 2 can be combined with each other, and new technical features can be formed by combination.
