FIG. DETAILED DESCRIPTION OF THE INVENTION

[0013] [Embodiment] 〔composition〕 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Figures 1 to 19 show the present embodiment. [Configuration of power supply and receiving system] First, the configuration of the power supply and reception system according to this embodiment will be described. FIG. 1 is a schematic diagram showing an example of the configuration of a power supply and reception system including a power supply and reception device 1 according to this embodiment. As shown in FIG. 1, the power supply and reception system includes a power supply and reception module 100 and an external device 200. The power supply / reception module 100 has a configuration in which a plurality of power supply / reception devices 1 according to this embodiment are connected in a ladder shape via power supply / reception sockets 2 and a pair of transmission units 30. The power supply / reception device 1 includes a power supply / reception socket 2 and a power supply / reception unit 6. Inside the power supply / reception unit 6, a power supply / reception body 8 is arranged.

[0014] Depending on the characteristics of the power supply / receiver 8 constituting the power supply / receive device 1, if the power supply / receiver 8 has the characteristics of a power supply such as a solar cell, the external device 200 will be a device equipped with a target for supplying generated energy such as a storage battery. On the other hand, if the power supply / receiver 8 has the characteristics of a power receiver that operates by receiving electrical energy such as an LED, the external device 200 will be a device equipped with a power source such as a battery. In the present embodiment, the configuration of a power supply / reception system in which the power supply / reception device 8 is a solar cell will be described below.

[0015] In this case, the power supply / receiving device 1 is a solar cell device, and the power supply / receiving module 100 is a solar cell module made up of a plurality of solar cell devices and a pair of transmission units 30. In addition, the external device 200 is a device that constitutes a solar power generation system together with the power supply / receiving module 100.

[0016] The power supply / reception module 100 supplies electrical energy generated by receiving light such as sunlight to an external device 200 via a transmission unit 30. A male connector 110 and a female connector 120 are attached to one end of the transmission unit 30, and a female connector 120 and a male connector 110 are attached to the other end. In the example shown in Fig. 1, one end of bus cables 150A and 150B are connected via the male connector 110 of one transmission unit 30 and the female connector 120 of the other transmission unit 30, respectively.

The bus cables 150A and 150B are connected to the power receiving connector 230 via connectors (not shown) attached to the other ends of the respective bus cables. The external device 200 charges the storage battery 210 with the generated energy received from the power supply / reception module 100 via the power receiving connector 230. At this time, the charging operation of the storage battery 210 is controlled by the charging control unit 220.

[0018] 1, the power supply and receiving system is configured by a power supply and receiving module 100 including a plurality of power supply and receiving devices 1, but the configuration is not limited to this. For example, the system may be configured by one power supply and receiving device 1, or the number of power supply and receiving devices 1 constituting the power supply and receiving module 100 may be different. [Configuration of power supply / receive socket 2] Next, the detailed configuration of the power supply / reception socket 2 according to this embodiment will be described.

FIG. 3 is a diagram showing the configuration of the power supply / receive socket 2 according to this embodiment, where (a) is a front view and (b) is a right side view. FIG. 4(a) is a rear view of the power supply / receive socket 2 according to this embodiment, and (b) is a diagram showing the arrangement of a current-carrying member 5 in the rear view of (a). FIG. 5(a) is a perspective view including the top, left side, and rear of the power supply / receive socket 2, and (b) is a perspective view including the bottom and rear of the power supply / receive socket 2. FIG. 6 is a diagram showing a specific example of the current-carrying member 5, where (a) is a plan view and (b) is a side view. In the following description, the flat surface side will be referred to as the top surface side and the bottom surface side as the bottom surface side. The same applies to Figure 7 and subsequent figures.

[0020] As shown in Figures 2(a) to 5(b), the power supply / reception socket 2 includes a connecting portion 3, an attachment portion 4, a current-carrying member 5, and a connecting member 50 (described later). The connecting portion 3 and the attachment portion 4 are integrally formed to form the socket body. The socket body is made of a resin material such as plastic. The connecting portion 3 is a portion that is connected to the transmission unit 30 of the power supply / reception socket 2, and has a configuration in which the lower end protrudes downward beyond the lower end of the attachment portion 4.

[0021] A circular countersink 31 is formed in the center of the upper surface of the connecting portion 3 when viewed from above. A through hole 32 is formed in the bottom surface of the countersink 31, and is concentric with the center of the countersink 31. The through hole 32 passes through the connecting portion 3 in the vertical direction.

[0022] At the connecting end 33, which is the lower end of the connecting part 3, a square frame 33a is formed along the outer edge when viewed from the bottom side, and a circular frame 33b is formed in the center inside the square frame 33a. The center of the circular frame 33b is concentric with the center of the through hole 32. Specifically, the square frame 33a and the circular frame 33b are formed by removing weight from the space between them, leaving a small area between them. When viewed from the front, the power supply / reception socket 2 has a generally semi-elliptical shape with rounded left and right corners at the top end.

[0023] The mounting portion 4 is a mounting portion for mounting the power supply / reception socket 2 to the power supply / reception unit 6. The mounting portion 4 extends straight toward the rear side in a direction perpendicular to the up-and-down direction of the connecting portion 3. The mounting portion 4 is cylindrical as shown in FIG. 4(a), and appears approximately circular when viewed from the rear side. The rear end of the mounting portion 4 is open, forming an opening 41. The internal space of the mounting portion 4 is in communication with the internal space of the connecting portion 3. On the inner peripheral surface of the end portion of the mounting portion 4 on the opening 41 side, a plurality of slit-shaped slit grooves 43 are formed at equal intervals along the circumferential direction and extending straight from the opening 41 side toward the connecting portion 3 side.

[0024] An internal space 36 is formed vertically in the center of the connecting portion 3 in the left-right direction when viewed from the front side. A first holding portion 34 and a second holding portion 35 are formed within the internal space 36. The first holding portion 34 has a first pillar portion 34a extending downward from the upper side of the inner periphery of the connecting portion 3. The first pillar portion 34a is cylindrical and concentric with the through hole 32. A first groove portion 34b is formed at the lower end of the first pillar portion 34a, opening to the rear side and having an inner periphery shaped to match the outer periphery of the current-carrying member 5. The second holding portion 35 has a second pillar portion 35a extending upward from the lower side of the inner periphery of the connecting portion 3. The second pillar portion 35a is cylindrical and concentric with the through hole 32. A second groove portion 35b is formed at the upper end of the second pillar portion 35a, opening to the rear side and having an inner periphery shaped to match the outer periphery of the current-carrying member 5. The lower end of the first pillar portion 34a and the upper end of the second pillar portion 35a are spaced apart from each other.

[0025] In the example shown in FIG. 4(b) and FIGS. 6(a) and 6(b), the current-carrying member 5 is a hexagonal nut. The current-carrying member 5 has six rectangular faces 5s in a side view and a screw hole 5h. With this configuration, the shapes of the inner peripheries of the first groove portion 34b and the second groove portion 35b are shaped to follow the shapes of three adjacent faces, including the face opposite to the one face 5s, so that one of the six faces 5s faces the back side of the current-carrying member 5.

[0026] As shown in Fig. 4(b), the current-carrying member 5 is disposed relative to the first and second groove portions 34b and 35b so as to straddle the space between them. Furthermore, the first and second pillar portions 34a and 35a have through-holes 32 formed concentrically with the center of the cylinders. That is, the through-hole 32 is comprised of an upper through-hole portion formed from the top surface of the connecting portion 3 to the first holding portion 34, and a lower through-hole portion formed from the second holding portion 35 to the connecting end 33 with the internal space 36 interposed therebetween. [Configuration of power supply / receive unit 6] Next, the detailed configuration of the power supply / receive unit 6 according to this embodiment will be described. Figure 7(a) is a diagram showing a portion of the power supply / reception socket 2 and the power supply / reception unit 6 according to this embodiment, and (b) is a front view showing a portion of the power supply / reception device 1 in a state in which the power supply / reception socket 2 according to this embodiment is attached to the end of the power supply / reception unit 6. 1, the power supply / reception device 1 includes two power supply / reception sockets 2 and one power supply / reception unit 6. That is, one power supply / reception socket 2 is attached to one end and one power supply / reception unit 6 to the other end. As shown in FIGS. 7(a) and 7(b), the power supply / reception unit 6 includes a cylindrical body 7, a power supply / reception body 8, two stems 9, two leads 10, and two power supply / reception members 11. The cylindrical body 7 has a cylindrical shape and is made of a transparent material such as transparent glass or a transparent resin material. In this embodiment, the cylindrical body 7 is made of glass that is sufficiently transparent to allow the solar cell inside to receive light.

[0027] In this embodiment, the power donor / receiver 8 is configured, for example, by a perovskite solar cell using perovskite crystals. A perovskite solar cell is manufactured by sequentially applying a solution (a mixture of a solvent and a solute) onto a substrate using printing technology to stack multiple layers, forming a sheet-like body.

[0028] That is, the power supply / receiver 8 is formed by rolling a sheet-like perovskite solar cell into a cylindrical shape and is placed inside the cylindrical body 7. This allows it to cover a circumferential range of 0 to 360°, making it possible to receive light and generate power at any angular position. In other words, it has a configuration with a high degree of installation flexibility. In addition, one end and the other end of the power supply / receiver 8 are each provided with a connection wire 81, one end of which is connected to the positive electrode of the power supply / receiver 8 and the other end of which is connected to the negative electrode. The connection wire 81 is formed, for example, from a single-core thin-wire electric cable. The power supply / receive unit 6 is not limited to a perovskite solar cell, and may be formed from other solar cells such as amorphous solar cells, semiconductor polymer solar cells, etc., as long as they can be deformed or configured into a cylindrical shape.

[0029] The two stems 9 are made of, for example, glass and are provided at one end and the other end of the cylindrical body 7. Each stem 9 is disk-shaped and provided so as to close the opening of the cylindrical body 7. A through-hole for attaching a lead 10 is provided in the center of each stem 9, penetrating the center of the disk surface, and bosses for supporting the lead 10 are provided on the outer disk surface and communicate with the through-holes.

[0030] The two leads 10 are cylindrical and made of metal. Each of the two leads 10 is inserted into a through-hole in the stem 9 and fixed to the stem 9, and is provided at one end and the other end of the cylindrical body 7 so that one end protrudes outward and the other end protrudes inward along the longitudinal direction. The other end of the lead 10 is connected to the other end of the connection wire 81 by soldering or the like. The lead 10 is cylindrical during manufacturing so that the inside of the cylindrical body 7 can be filled with nitrogen gas, but after filling with nitrogen gas, the ends of the cylindrical body 7 are closed by crimping or the like to seal them.

[0031] In this embodiment, the two power supply / reception members 11 are each made of a metal conical coil spring, and the small diameter end thereof is attached to the other outer end of the lead 10 at one end or the other end of the cylindrical body 7. Specifically, the inner diameter of the small diameter end of the power supply / reception member 11 is configured to be the same diameter as or slightly larger than the outer diameter of the lead 10, and the other end of the lead 10 is inserted inside the member 11 and attached. [Configuration of transmission unit 30] Next, a detailed configuration of the transmission unit 30 according to this embodiment will be described.

[0032] FIG. 8(a) is a plan view of the transmission unit 30, and (b) is a plan view of the transmission board 25 that constitutes the transmission unit 30. FIG. 9A is a diagram showing the storage member 20 that constitutes the transmission unit 30, where (a) is a plan view, (b) is a side view, (c) is a bottom view, and (d) is a plan view when a grommet 23 is attached. FIG. 9B is a diagram showing a specific configuration of the storage member 20. FIG. 10 is a diagram showing an example configuration of the grommet 23, where (a) is a plan view and (b) is a side view. FIG. 11(a) is a cross-sectional view taken along line A-A' in FIG. 8(a), and (b) is a cross-sectional view taken along line B-B' in FIG. 8(a). The transmission unit 30 includes a housing member 20, a plurality of grommets 23, and a transmission board 25, as shown in FIGS. 8(a) to 11(b). The storage member 20 includes an upper frame 21 and a lower frame 22. The upper frame 21 includes a cover portion 21a that is rectangular in plan view and has the same width as the lower frame 22, and a pair of legs 21b that extend downward from both ends of the cover portion 21a in the width direction (short side direction). The pair of legs 21b extend downward slightly, then bend outward at an angle of 90 degrees, and then extend straight downward again. The upper frame 21 further includes a pair of claws 21c that support a transmission board 25 provided on the inner upper part of the pair of legs 21b. Furthermore, the upper frame 21 has a plurality of through holes 21h that are equally spaced along the longitudinal direction and for attaching grommets 23. The lower frame 22 includes a receiving portion 22a and a pair of retaining portions 22b for preventing the leg portions 21b of the upper frame 21 from coming off. The receiving portion 22a includes a base portion having a rectangular, elongated plate shape when viewed from the bottom, and side wall portions having a rectangular, elongated plate shape when viewed from the side and erected at both ends of the upper surface of the base in the width direction. That is, the receiving portion 22a is substantially U-shaped when viewed from one end in the longitudinal direction. The pair of retaining portions 22b are provided on the inner upper part of the side wall portions and are formed to protrude inward from each other. By joining the upper frame 21 and lower frame 22 configured as described above, the lower part of the retaining portion 22b of the lower frame 22 abuts against the upper part of the shoulder formed by a 90° bend of the leg portion 21b of the upper frame 21. In addition, the lower surfaces of both ends of the covering portion 21a abut against the upper ends of the side wall portions of the receiving portion 22a of the lower frame 22. This forms a rectangular cylindrical storage member 20. With this configuration, maintenance such as repairs and part replacement can be easily performed by removing the lower frame 22 from the upper frame 21.

[0033] The storage member 20 can be made of, for example, a metal material such as aluminum or a resin material. Note that the storage member 20 is often installed outdoors when installed for the purpose of solar power generation. Therefore, it is desirable to make the storage member 20 from a lightweight and sturdy material in consideration of portability and durability such as corrosion resistance. As shown in Figures 10(a) and (b), the grommet 23 has an upper portion 23a, a lower portion 23b, an intermediate portion 23c formed between the upper portion 23a and the lower portion 23b, and a through hole 23h that passes vertically through the upper portion 23a, the intermediate portion 23c, and the lower portion 23b.

[0034] The upper portion 23a has an outer diameter larger than that of the upper end portion of the lower portion 23b, and the upper end portion of the lower portion 23b has an outer diameter larger than that of the intermediate portion 23c. The outer diameters of the upper portion 23a and the intermediate portion 23c are each approximately uniform from top to bottom, while the outer diameter of the lower portion 23b becomes smaller as it goes downward.

[0035] Here, the outer diameter of the upper portion 23a is configured to be approximately the same as or slightly larger than the inner diameter of the circular frame 33b of the connecting portion 3 of the power supply / reception socket 2. Furthermore, the outer diameter of the lower end portion of the lower portion 23b is configured to be smaller than the inner diameter of the through hole 21h of the storage member 20, and the outer diameter of the upper end portion of the lower portion 23b is configured to be larger than the inner diameter of the through hole 21h. Furthermore, the length in the vertical direction of the middle portion 23c is configured to be approximately the same as the plate thickness of the upper surface portion of the storage member 20, and the outer diameter of the middle portion 23c is configured to be approximately the same as or slightly larger than the inner diameter of the through hole 21h. Note that the grommet 23 is configured from an elastic material such as rubber.

[0036] With this configuration, when the lower portion 23b of the grommet 23 is pushed into the through-hole 21h from above, the lower portion 23b deforms and passes through the through-hole 21h, becoming positioned inside the storage member 20. At this time, the upper end of the lower portion 23b returns to its original state from its deformed state, causing the upper end to become bent, preventing the grommet 23 from falling out of the through-hole 21h. Furthermore, the upper portion 23a, which has a larger diameter than the through-hole 21h, abuts against the upper surface of the storage member 20, preventing the grommet 23 from being pushed in any further. Furthermore, the lower end of the grommet 23 abuts against the upper surface of the transmission board 25 (see FIG. 11(b)). In this manner, the grommet 23 is attached to the storage member 20 via the through-hole 21h. In the examples shown in FIGS. 8(a) and 9A(d), the grommets 23 are attached to every other one of the multiple through-holes 21h.

[0037] When the transmission board 25 is placed inside the housing member 20, through holes (not shown) are provided at positions concentric with the through holes 21h, and press-fit nuts 26 are press-fitted into these through holes. As shown in Figures 11(a) and 11(b), after the press-fit nuts 26 are press-fitted into the transmission board 25, the lower end of the press-fit nuts 26 protrudes downward from the lower surface of the transmission board 25. The press-fit nuts 26 also have a screw hole that passes through them vertically. The surface of the transmission board 25 is coated with a metal material, and this metal coating forms a transmission line pattern 25mc. The transmission line pattern 25mc is electrically connected to the press-fit nut .

[0038] Furthermore, connection portions 27 for connecting cables are provided at one end and the other end of the transmission board 25 in the longitudinal direction. For example, a male connector 110 or a female connector 120 is attached to the connection portions 27 via a short cable. The transmission board 25 is inserted between the claw portions 21c of the housing member 20 and disposed inside the housing member 20. As a result, both ends of the transmission board 25 in the lateral direction are supported by the claw portions 21c. [Configuration of connection of power supply / reception socket 2 to transmission unit 30] Next, a connection structure between the power supply / reception socket 2 and the transmission unit 30 according to this embodiment will be described.

[0039] 12(a), 12(b), and 12(c) are diagrams showing a procedure for connecting the power supply and receiving socket 2 to the transmission unit 30, as viewed from one end of the transmission unit 30 in the longitudinal direction. FIGS. 13(a) and 13(b) are diagrams showing an example of a connecting member 50. FIGS. 14A(a), 14A(b), and 14A(c) are partially enlarged views showing detailed steps for screwing the connecting member 50 into the press-fit nut 26. The power supply and receiving socket 2 is not shown in FIGS. 14A(a) to 14A(c). FIG. 14B is a diagram for explaining how the power supply and receiving socket 2 rotates relative to the transmission unit 30. FIG. 15(a) is a plan view showing the power supply and receiving socket 2 connected to the transmission unit 30, and FIG. 15(b) is a cross-sectional view taken along line CC' in FIG. 15(a). First, we will explain the connecting member 50. The connecting member 50 is a member for connecting the power supply / reception socket 2 to the transmission unit 30. In this embodiment, the connecting member 50 is made up of one screw member, as shown in Figures 13(a) and (b).

[0040] Specifically, as shown in FIGS. 13(a) and 13(b), the connecting member 50 is mainly composed of a hexagon socket bolt having a screw head 50h and a screw shaft 50a. Specifically, an unthreaded portion 50r without threads is formed around a portion of the entire circumference of the screw shaft 50a on the tip end 50t side of the hexagon socket bolt. The surface of the unthreaded portion 50r is, for example, a smooth surface. The screw head 50h has a diameter larger than the diameter of the screw shaft 50a, and a hexagon socket 50p is formed in the center of the screw head 50h when viewed from above. In other words, the connecting member 50 is composed of a normal hexagon socket bolt with threads removed from a portion of the entire circumference on the tip end side.

[0041] The length of the unthreaded portion 50r of the connecting member 50 is longer than the length of the threaded hole of the press-fit nut 26. Furthermore, the overall length of the connecting member 50 is such that the tip portion 50t extends through the threaded hole of the press-fit nut 26 when the lower end of the screw head 50h abuts against the bottom surface of the counterbore 31 of the connecting portion 3. Specifically, the length is such that the end of the tip portion 50t opposite to the tip side abuts against the lower end of the press-fit nut 26 or can abut against the lower surface by applying a force to the connecting member 50 in the opposite direction to the tip side. Next, a procedure for connecting the power supply / reception socket 2 to the transmission unit 30 will be described. 12(a), the power supply / reception socket 2 is attached to the grommet 23 attached to the housing member 20. Specifically, the power supply / reception socket 2 is attached to the grommet 23 by fitting the grommet 23 inside the circular frame 33b of the connecting portion 3. Next, as shown in Figure 12(b), the connecting member 50 is inserted from the top side into the through hole 32 of the connecting portion 3, and then screwed into the threaded holes of the conductive member (hex nut) 5 arranged in the first holding portion 34 and the second holding portion 35 using a hex wrench.

[0042] As the connecting member 50 is screwed into the current-carrying member 5, the tip portion 50t of the connecting member 50 passes through the current-carrying member 5. As the connecting member 50 is further screwed, the tip portion 50t passes through the internal space 36 and the through hole 32 formed in the second holding portion 35, and is inserted into the through hole 23h of the grommet 23. As the connecting member 50 is continuously screwed, the tip portion 50t advances inside the grommet 23 and enters the inside of the storage member 20, as shown in FIG. 14A(a).

[0043] 14A(b), by continuing to screw the connecting member 50 into the current-carrying member 5, the tip 50t passes through the grommet 23, and the passed tip 50t is screwed into the threaded hole of the press-fit nut 26. By further screwing, the tip 50t of the connecting member 50 passes through the press-fit nut 26 and comes out to the underside of the transmission board 25 and the press-fit nut 26, as shown in FIGS. 12(c) and 14(c).

[0044] In this state, as shown in FIG. 15(b), the upper end of the current-carrying member 5 abuts against the lower end surface of the first holding portion 34, and the unthreaded portion 50r is positioned within the threaded hole of the press-fit nut 26. Therefore, the connecting member 50 cannot be screwed in any further. The elastic grommet 23 extends downward (pressed against the upper surface of the transmission board 25), and the reaction force presses the upper end of the tip portion 50t against the lower end of the press-fit nut 26. The state shown in FIG. 15(b) establishes electrical continuity between the current-carrying member 5 and the connecting member 50, and also between the connecting member 50 and the press-fit nut 26, thereby establishing electrical continuity between the current-carrying member 5 and the press-fit nut 26. The press-fit nut 26 is electrically connected to the transmission line pattern 25mc of the transmission board 25, establishing electrical continuity between the current-carrying member 5 and the transmission line pattern 25mc of the transmission board 25. In order to ensure electrical continuity between the current-carrying member 5 and the connecting member 50, a conductor may be provided between the current-carrying member 5 and the connecting member 50.

[0045] Furthermore, the power supply / receiving socket 2 is in an unconstrained state because the unthreaded portion 50r of the connecting member 50 is disposed in the threaded hole of the press-fit nut 26, and the connecting member 50 is also in an unconstrained state within the through-hole 23h of the grommet 23, although it is somewhat tightened by the elastic force of the grommet 23. Therefore, as shown in Fig. 14B, the entire power supply / receiving socket 2 can be rotated relative to the transmission unit 30 with the connecting member 50 as the rotation axis. The connecting member 50 can be removed by using a hexagonal wrench to turn the connecting member 50 in the direction that loosens the screw.

[0046] After connecting the power supply / reception socket 2 to the transmission unit 30, the cap 60 is attached to cover the screw head 50h, as shown in FIG. 15(a). The cap 60 has a disk-shaped covering portion and a cylindrical shank portion that protrudes concentrically from the underside of the covering portion and has a smaller diameter than the covering portion. Specifically, by inserting the shank portion of the cap 60 so as to cover the upper end of the screw head 50h, the covering portion covers the entire upper part of the screw head 50h. The cap 60 is made of an insulating material such as rubber, and serves not only a cosmetic purpose but also a role in preventing electric shock because current flows to the connecting member 50 via the current-carrying member 5. 15(b), a groove can be provided around the through-hole 32 on the bottom surface of the counterbore 31, and an O-ring 70 can be placed between this groove and the lower end of the screw head 50h. This prevents water from entering the interior through the through-hole 32. Furthermore, the press-fit nut 26 and the tip portion 50t of the connecting member 50 may be coated with adhesive (for example, silicon adhesive) to ensure waterproofing. [Assembly process of power supply / receive unit 6] Next, the assembly process of the power supply / receive unit 6 will be described. FIG. 16 is a diagram for explaining an example of an assembly process for the power supply / receive unit 6. In FIG. First, a cylindrical body 7, a power supply / reception body 8 (made of a solar cell sheet), a stem 9 with two leads 10, and two power supply / reception members 11 made of conical coil springs are prepared. Although not shown, the stem 9 with the lead 10 has a cylindrical lead 10 attached to the center of the disk-shaped main body of the stem 9 before it is attached to the cylindrical body 7, penetrating the disk surface.

[0047] Next, as shown in Fig. 16(1), the cylindrically rolled power supply / receiver 8 is placed inside the tube 7. Subsequently, as shown in Fig. 16(2), connection wires 81 extending from one end and the other end of the power supply / receiver 8 are electrically connected to one end of the lead 10, which has been attached to the stem 9 in advance, by soldering, welding, or the like.

[0048] Subsequently, for example, a dedicated heat treatment device (not shown) is used to attach the disk-shaped stem 9 to one end and the other end of the cylindrical body 7 by heat treatment. For example, this heat treatment device is configured to attach the stem 9 by melting the end of the cylindrical body 7 with heat, and is configured to apply heat to the end of the cylindrical body 7 while cooling the other parts. Note that this configuration is not limited to this, and a configuration in which the flare stem is formed by a dedicated machine may also be used. Next, a nitrogen purge machine (not shown) is used to first remove air (oxygen, etc.) from the inside of the cylindrical body 7 via cylindrical leads 10 provided on one end and the other end of the cylindrical body 7, creating a vacuum. Thereafter, nitrogen gas is filled into the inside of the cylindrical body 7 via the cylindrical leads 10.

[0049] Next, as shown in Fig. 16(3), the small diameter portion of the power supply / reception member 11 is attached to the other end of each lead 10. In Fig. 16(3), only a portion of the lead 10 protruding outside the cylindrical body 7 is shown on the right side to explain deformation due to crimping.

[0050] Specifically, the other end of the lead 10 is inserted into the small-diameter end of the power supply / receive member 11. Next, the tip of the lead 10 on one end side and the other end side of the cylindrical body 7 is crimped to form a crimped portion 10k. As shown in the right diagram of Figure 16 (3), the crimped portion 10k becomes wider as it approaches the tip. This seals nitrogen gas inside the cylindrical body 7. In other words, the inside of the cylindrical body 7 is oxygen-free, making it possible to suppress oxidation of the power supply / receive member 8. With the above, the assembly of the power supply / receive unit 6 is completed.

[0051] The width of the tip of the crimping portion 10k is configured to be longer than the diameter of at least the small-diameter end of the power supply / reception member 11. That is, by crimping the tip of the lead 10 after attaching the power supply / reception member 11, the crimping portion 10k acts as a stopper to prevent the power supply / reception member 11 from falling off the lead 10. [Assembly process of power supply / reception device 1] Next, the assembly process of the power supply / reception device 1 will be described. FIG. 17 is a diagram for explaining an example of an assembly process for the power supply and reception device 1. In FIG. The assembly process for the power supply / reception device 1 will be described below. First, as shown in FIG. 17(1), the power supply / reception unit 6 and two power supply / reception sockets 2 are prepared. Next, as shown in the cross-sectional view of the power supply / reception socket 2 in Figure 17 (2), an application device such as a dispenser (not shown) is used to apply, for example, a slow-drying adhesive 500 along the slit groove 43 on the inside of the power supply / reception socket 2.

[0052] 17(3), one end of the power supply / receiving unit 6 is inserted into the power supply / receiving socket 2 to which the adhesive 500 has been applied, and the power supply / receiving socket 2 is attached to one end of the power supply / receiving unit 6. As a result, the large diameter end of the power supply / receiving member 11 is pressed against the current-carrying member 5, and the power supply / receiving member 11 enters a contracted state. In this way, the current-carrying member 5 and the power supply / receiving member 11 are brought into an electrically conductive state, and the power supply / receiving member 11 is electrically conductive with the transmission board 25 via the connecting member 50 which is electrically conductive with the current-carrying member 5 and the transmission board 25.

[0053] Next, with the power supply / receiving socket 2 fixed, the power supply / receiving unit 6 is rotated in one direction (for example, the direction of the arrow in FIG. 17(3)). As a result, the power supply / receiving unit 6 rotates while the large-diameter end of the power supply / receiving member 11 slides on the surface 5s of the current-carrying member 5. As a result, the adhesive 500 applied to the slit groove 43 of the power supply / receiving socket 2 is applied to almost the entire portion of one end of the power supply / receiving unit 6 that faces the slit groove 43.

[0054] Next, although not shown, before the adhesive 500 on one end of the power supply / receiving unit 6 dries, slow-drying adhesive 500 is similarly applied along the slit groove 43 on the inside of another power supply / receiving socket 2, and the other end of the power supply / receiving unit 6 is inserted into this power supply / receiving socket 2. Thereafter, with both power supply / receiving sockets 2 fixed, the power supply / receiving unit 6 is rotated in the same direction, and the adhesive 500 applied in the slit groove 43 is applied to almost the entire portion of the other end of the power supply / receiving unit 6 that faces the slit groove 43. Thereafter, the adhesive 500 is dried at both ends of the power supply / receiving unit 6 using a drying device (not shown) or by natural drying, whereby the power supply / receiving sockets 2 are fixed to both ends of the power supply / receiving unit 6, and the power supply / receiving device 1 is completed as shown in (4) of Figure 17. Here, FIG. 18 is a perspective view showing how the power supply / reception socket 2 of the power supply / reception device 1 is connected to the transmission unit 30. As shown in FIG.

[0055] 14A(a) to 14A(c) and 14B have been described with reference to an example where a single power supply / reception socket 2 is connected to the transmission unit 30. In reality, as shown in FIG. 18, the power supply / reception socket 2 is attached to both ends of the power supply / reception unit 6, and then the power supply / reception socket 2 is connected to the transmission unit 30. [Regarding the rotational movement of the power supply / receive device 1] Next, a rotational operation in the state of the power supply / reception module 100 including a plurality of power supply / reception devices 1 will be described. 19(a), (b) and (c) are diagrams showing the deformation state of the power supply and reception module 100 due to the rotational movement of a plurality of power supply and reception devices 1. FIG.

[0056] The power supply and reception module 100 can rotate each power supply and reception device 1 in the rotation direction (or the reverse direction) shown in FIG. 19(b) from the straight ladder-like state shown in FIG. 19(a). As a result, one side of the transmission unit 30 can be moved upward and the other side can be moved downward in a plan view of the paper surface of FIG. 19. Finally, as shown in FIG. 19(c), it can be rotated until there is no gap between the power supply and reception devices 1. Thereby, the width dimension W1 shown in FIG. 19(a) can be narrowed to the width dimension W2 (<W1) shown in FIG. 19(c). This width dimension W2 can be further narrowed by widening the gap between the power supply and reception devices 1 and expanding the rotation range. 〔Effects of the Embodiment〕

[0057] In this embodiment, the power supply and reception socket 2 includes a connection portion 3 for connecting to a transmission unit 30 including a transmission substrate 25 for transmitting power and a rectangular tube-shaped storage member 20 for storing the transmission substrate 25, and a cylindrical attachment portion 4 extending in a direction orthogonal to the connection direction (vertical direction of the connection portion 3) of the connection portion 3 for attachment to the power supply and reception unit 6, a socket body, an energization member 5 disposed inside the connection portion 3 and exposed toward the opening of the attachment portion 4 so as to contact a power supply and reception member 11 provided at an end of the power supply and reception unit 6, and a connection member 50 configured by a conductor attached so as to extend from the connection portion 3 to the inside of the storage member 20, for conducting the energization member 5 and the transmission line pattern 25mc of the transmission substrate 25 and connecting the socket body rotatably about its own axis.

[0058] With such a configuration, the power supply and reception socket 2 can be rotated around the axis of the connection member with respect to the transmission unit 30. For example, if a power supply and reception module 100 having a configuration in which a plurality of power supply and reception devices 1 are connected to a pair of transmission units 30 is installed on a building wall. In this case, when the building moves due to distortion or shaking of the building, the power supply and reception unit can rotate to absorb the movement of the building. As a result, the load applied to each component of the power supply and reception module 100 can be reduced, so that it is possible to prevent or reduce damage to the power supply and reception module 100 caused by the movement of the building.

[0059] Furthermore, in a power supply / receive module 100 configured such that multiple power supply / receive devices 1 are connected in a ladder-like manner to a pair of transmission units 30, the power supply / receive module 100 can be folded by rotating each power supply / receive socket 2, thereby increasing the length but reducing the width to create a compact, easy-to-carry state.

[0060] Furthermore, in this embodiment, the connecting member 50 is composed of a single screw member, the current-carrying member is composed of a nut, the connecting portion 3 is provided with a through hole 32 through which the connecting member 50 can be inserted and which is concentric with the screw hole of the nut, and at a position corresponding to the through hole 32 on the surface of the side of the storage member 20 that connects to the connecting portion 3, a through hole 21h is provided that penetrates the surface and through which the connecting member 50 can be inserted, and the connecting member 50 is configured so that its tip reaches the transmission board 25 stored in the storage member 20 via the through hole 32, the screw hole of the nut and through hole 21h.

[0061] Furthermore, the connecting member 50 is configured to have an unthreaded portion 50r that has no threads around the entire circumference and is formed on a part of the tip side of the screw shaft 50a, and the transmission board 25 has a substrate on which a transmission line pattern 25mc is formed, and this substrate is provided with a conductive press-in nut 26 that has a threaded hole into which the connecting member 50 can be screwed and that is shorter than the length of the unthreaded portion 50r, and the connecting member 50 is configured to have a length such that when the socket body is connected to the transmission unit 30, the tip portion 50t that has threads beyond the unthreaded portion 50r can pass through the end of the screw-in direction of the screw hole of the press-in nut 26.

[0062] With this configuration, the connecting member 50 can be threaded into the threaded hole of the current-carrying member 5 via the through hole 32, and can also be threaded into the threaded hole of the press-fit nut 26 in the storage member 20 via the through hole 21h. In addition, the tip 50t of the connecting member 50 can be removed from the end of the threaded hole of the press-fit nut 26. As a result, the unthreaded portion 50r is positioned within the threaded hole of the press-fit nut 26, and the connecting member 50 cannot be threaded any further. The unthreaded portion 50r allows the connecting member 50 to rotate freely, and the power supply / receiving socket 2 can be rotated around the connecting member 50 as the rotation axis. Furthermore, the power supply / reception device 1 can be easily attached to and detached from the transmission unit 30 by attaching and detaching the connecting member 50, which is a screw member.

[0063] In addition, in this embodiment, a grommet 23 having a through hole 23h with a diameter smaller than the outer diameter of the connecting member 50 and made of an elastic material is attached to the through hole 21h, and the connecting member 50 is inserted into the inside of the storage member 20 through the through hole 23h of the grommet 23. With this configuration, the grommet 23 can support the connecting member 50 in a stable state, and the reaction force of the grommet 23 can maintain electrical continuity between the tip 50t of the connecting member 50 and the press-fit nut 26. In addition, in this embodiment, when the power supply / reception socket 2 is attached to the power supply / reception unit 6, the power supply / reception member 11 and the current-carrying member 5 are in contact with each other but are not fixed to each other. In this embodiment, the power supply / reception member 11 is configured as a coil spring, the current-carrying member 5 is configured as a hexagonal nut, and the coil spring is in contact with the surface 50s of the hexagonal nut in a contracted state.

[0064] With this configuration, when bonding the power supply / receiving socket 2 to the power supply / receiving unit 6 with the adhesive 500, the power supply / receiving unit 6 can be rotated with the power supply / receiving socket 2 attached so that the adhesive 500 is evenly applied. In other words, even when the power supply / receiving unit 6 is rotated, the coil spring slides on the surface 50s while being pressed against the surface 50s, so problems such as disconnection or poor contact due to rotation do not occur. In addition, in this embodiment, the mounting portion 4 has a cylindrical inner surface, and at least on the opening side of the inner surface, it is configured to have a plurality of slit-shaped slit grooves 43 extending from the opening toward the connecting portion 3 and formed at equal intervals in the circumferential direction.

[0065] With this configuration, after applying adhesive 500 to slit groove 43, power supply / receiving socket 2 can be attached to power supply / receiving unit 6, and in this state power supply / receiving unit 6 can be rotated to evenly apply adhesive 500. Furthermore, by drying, power supply / receiving socket 2 can be reliably fixed to the end of power supply / receiving unit 6.

[0066] In this embodiment, the socket body is configured to have an internal space 36, a first holding portion 34, and a second holding portion 35, which are open toward the opening of the attachment portion 4 inside the connecting portion 3 of the socket body and are used to place the current-carrying member 5. With this configuration, the current-carrying member 5 can be easily placed inside the connecting portion 3. In addition, in this embodiment, in a state where the socket body is connected to the transmission unit 30, a cap 60 for covering the head (screw head 50h) of the connecting member 50 is provided. With this configuration, the screw head 50h can be covered without being exposed, which can make up for poor appearance and prevent electric shock due to contact with bare hands, etc. In addition, in this embodiment, the connecting portion 3 is provided with a countersink 31 that accommodates the screw head 50h of the connecting member 50 that is arranged to surround the upper end of the through hole 32, and an O-ring 70 is interposed between the screw head 50h accommodated in the countersink 31 and the bottom surface of the countersink 31. With this configuration, it is possible to prevent water from entering the inside of the socket body through the through-hole 32. [Correspondence] In this embodiment, the transmission board 25 corresponds to the transmission member, the conductive member 5 corresponds to the conductive portion, the through hole 32 corresponds to the first through hole, the through hole 21h corresponds to the second through hole, the through hole 23h corresponds to the third through hole, and the press-fit nut 26 corresponds to the support member. In this embodiment, the grommet 23 and the press-fit nut 26 correspond to the support portion, and the cap 60 corresponds to the covering member. [Modification]

[0067] In the above embodiment, the storage member 20 is configured to have each cylindrical shape by joining two members, but is not limited to this configuration and may be configured from a single rectangular cylindrical body. Furthermore, in the above embodiment and its modified examples, a slit-shaped slit groove 43 is provided on the inner periphery of the mounting portion 4 of the power supply / reception socket 2, but this configuration is not limited to this, and a spiral groove may also be formed.

[0068] Furthermore, in the above embodiment and its modified examples, the connecting member 50, which is mainly composed of a hexagon socket bolt, is configured to be screwed into the threaded hole of the current-carrying member 5, which is composed of a hexagonal nut, but this configuration is not limited to this. As long as the current-carrying member 5 and the connecting member 50 can be electrically connected, other configurations may be used, such as using a hexagonal nut with a larger diameter than the outer diameter of the connecting member, inserting the connecting member 50 into the threaded hole of the hexagonal nut without screwing it in, and establishing electrical connection between the current-carrying member 5 and the connecting member 50 via a copper sheet or the like in the threaded hole of the hexagonal nut. Furthermore, in the above embodiment and its modified examples, the current-carrying member 5 is configured as a hexagonal nut, but is not limited to this configuration and may be configured as another polygonal nut such as a square nut. Furthermore, in the above-described embodiments and their modifications, the power supply / reception sockets 2, 2A are configured to be substantially cylindrical, but are not limited to this configuration, and the outer shape may be other shapes as long as only the inside is cylindrical.

[0069] In the above embodiment and its modified examples, the power supply / receive member 11 is configured from a conical coil spring, but is not limited to this configuration. As long as the electrical connection between the lead 10 and the current-carrying member 14 can be ensured, the power supply / receive member 11 may be configured from other spring members or non-elastic members.

[0070] In the above embodiment and its modified examples, the power supply / reception unit 6 is attached to the power supply / reception socket 2 configured to connect the power supply / reception unit 6 to the transmission unit 30, but the present invention is not limited to this configuration. It is also applicable to sockets with other configurations as long as they have a similar current-carrying configuration with the power supply / reception member 11.

[0071] Furthermore, although specific embodiments and modifications thereof have been described above, these embodiments and modifications are merely examples and are not intended to limit the scope of the present invention.
