The first and second coupling portions 21 a and 21 b are rotatable between a first position (first rotation position) and a second position (second rotation position) by operating the lever 212 . The first position is a position where the pair of projections 213, 213 are aligned in the longitudinal direction of the body portion 24. As shown in FIG. The second position is a position where the pair of projections 213, 213 are aligned in the width direction of the body portion 24. As shown in FIG. For example, in FIG. 6, the first coupling portion 21a and the second coupling portion 21b are in the first position . In addition , in FIG. 9, the first coupling portion 21a at the first position is indicated by a chain double-dashed line , and the first coupling portion 21a at the second position is indicated by a solid line . In other words, the first and second coupling portions 21a and 21b can pass through the opening 43 at the first position, but cannot pass through the opening 43 at the second position.

The first coupling portion 21 a and the second coupling portion 21 b are attached to the body portion 24 using attachment holes 2401 of the body portion 24 . That is, each of the first coupling portion 21a and the second coupling portion 21b is inserted into the mounting hole 2401 such that the protrusion 211 can rotate about its central axis. Here, around the attachment hole 2401 in the body portion 24, there are a connecting portion 26 and a support portion 27. As shown in FIG. As shown in FIG. 7, the support portion 27 is located within the recess 2403 of the first surface 240a, and the attachment hole 2401 is exposed through the opening 27a of the support portion 27. As shown in FIG. In addition, the connecting portion 26 is located inside the concave portion 2403 of the main body portion 24, and the support portion 27 is fitted in the fitting cavity 260a. Therefore, the projecting portion 211 is inserted into the mounting hole 2401 through the opening 27a of the supporting portion 27. As shown in FIG. The flat plate portion 260 and the support portion 27 of the connecting portion 26 are between the first surface 240 a and the lever 212 . Thereby, the strength of fixing the connecting portion 26 to the main body portion 24 can be improved. In this embodiment, the support portion 27 has a thickness greater than that of the flat plate portion 260 . Therefore, the support portion 27 supports the lever 212 so as not to contact the connecting portion 26 (the flat plate portion 260). In particular, since the support portion 27 has an annular shape surrounding the projecting portion 211, the support of the lever 212 by the support portion 27 is stable. As described above, the connecting portion 26 has the locking protrusion 260c. The locking projection 260c fits into a locking hole 2121 (see FIG. 4) on the surface of the lever 212 on the side of the connecting portion 26 when the lever 212 of the duct connecting portion 21 is at a predetermined position. Here, the predetermined position is the position of the lever 212 when the protrusion 211 is in a position where it cannot pass through the opening 43 (that is, the second position). In other words, by fitting the locking protrusion 260c into the locking hole 2121, the possibility of the lever 212 unintentionally moving from the predetermined position can be reduced. This reduces the possibility that the first coupling portion 21a or the second coupling portion 21b moves from the second position to the first position unintentionally. That is, it is possible to reduce the possibility that the duct connection portion 21 will unintentionally come off the wiring duct 40 .

Such a communication interface based on power line carrier communication may have a conventionally well-known configuration, so detailed description thereof will be omitted.

The first communication section 31 is electrically connected to the duct connection section 21 . More specifically, the first communication section 31 is electrically connected to the first and second terminals 214a, 214b of the first coupling section 21a of the duct connection section 21. As shown in FIG. Therefore, by attaching the duct connection portion 21 to the wiring duct 40 , the first communication portion 31 is electrically connected to the wiring duct 40 via the duct connection portion 21 .

(1.3) Attachment Method The connection device 10 is attached to the wiring duct 40 as follows. First, if necessary, the lever 212 is operated to set the first and second coupling portions 21a and 21b to the first position. In this state, the first and second coupling portions 21 a and 21 b are inserted into the case 42 through the opening 43 of the wiring duct 40 . At this time, if the connection device 10 is positioned incorrectly with respect to the wiring duct 40, the duct facing surface 2411 of the base portion 241 hits the tip of the protrusion 44, so that the wiring duct 40 of the first and second coupling portions 21a and 21b is displaced. is blocked from being inserted into the case 42 . Therefore, erroneous connection can be prevented. In other words, it is possible to reduce the possibility of attaching the connection device 10 to the wiring duct 40 in a wrong way. On the other hand, if the connection device 10 is positioned correctly with respect to the wiring duct 40 , the duct-facing surface 2411 of the base portion 241 does not contact the tip of the projection 44 . Therefore, the insertion of the wiring duct 40 into the case 42 of the first and second coupling portions 21a and 21b is not hindered. Therefore, the first and second coupling portions 21 a and 21 b can be inserted into the case 42 of the wiring duct 40 .

After inserting the first and second coupling portions 21a and 21b into the case 42 through the opening 43 of the wiring duct 40, the lever 212 is operated to move the first and second coupling portions 21a and 21b from the first position to the second position. 2 position. As a result, as shown by solid lines in FIG. 9, the pair of projections 213, 213 are physically attached to both edges of the opening 43 of the case 42 of the wiring duct 40 at each of the first and second coupling portions 21a, 21b. supported by Also, in the first coupling portion 21a, the first, second and third terminals 214a, 214b and 214c are electrically connected to the first, second and third conductors 41a, 41b and 41c of the wiring duct 40, respectively. .

Therefore, at least one of the first and second wall portions 242 a and 242 b can function as a portion that reduces the shaking of the main body portion 24 along the width direction of the wiring duct 40 . Therefore, according to the connection device 10, the stability of the mechanical connection with the wiring duct 40 can be improved.

Furthermore, the connection device 10 has a first contact portion (first projection 244a) and a second contact portion (second projection 244b) on the first region 2411a and the second region 2411b of the duct facing surface 2411 facing the wiring duct 40. Each has. When the main body portion 24 is held by the wiring duct 40 at the duct connection portion 21 , the first contact portion (the first protrusion 244 a ) contacts the first portion 424 of the wiring duct 40 . Also, the second contact portion (second protrusion 244 b ) contacts the second portion 425 of the wiring duct 40 . Therefore, at least one of the first and second contact portions can function as a portion that reduces shaking of the main body portion 24 along the width direction of the wiring duct 40 . Therefore, according to the connection device 10, the stability of the mechanical connection with the wiring duct 40 can be improved.

In particular, the connecting portion 26 is a separate member from the body portion 24 and is fixed to the body portion 24 . Therefore, the connecting portion 26 can be made of a material having a higher strength than the main body portion 24 . Therefore, when the connection device 10 is hung on the wiring duct 40 by the string-like body 93, the possibility that the connecting portion 26 will be damaged and the connection device 10 will fall can be reduced. Therefore, the connection device 10 and the wiring duct 40 can be easily connected by the string-like body 93 and the possibility of the connection device 10 falling from the wiring duct 40 can be reduced by the presence of the connecting portion 26 .

A second end of the string-like body 93 is fixed to a connector 94 . Examples of the string-like body 93 include strings and wires. Although the string-like body 93 is not particularly limited, it is desirable that it has strength enough to withstand at least the weight of the connection device 10 . The connecting tool 94 is used to easily attach the string-like body 93 to the connecting portion 26 . The connector 94 is connected to the connecting part 26 by passing a part of the connecting tool 94 through the connecting hole 26 a of the connecting part 26 .

These restricting portions 2485a and 2485b are provided to restrict the rotation range of the lever 212. As shown in FIG. Excessive turning of the lever 212 can be prevented by the restricting portions 2485a and 2485b. Therefore, the possibility of damage to the duct connecting portion 21 can be reduced. More specifically, the restricting portions 2485 a and 2485 b limit the rotation range of the lever 212 by coming into contact with the lever 212 . The restricting portions 2485a and 2485b set the rotation range of the lever 212 to the position where the corresponding coupling portion (first coupling portion 21a or second coupling portion 21b) is located at the first position, and the position where the corresponding coupling portion (first coupling portion 21b) is located at the first position. The position where the portion 21a or the second coupling portion 21b) is positioned at the second position.

As shown in FIG. 25, a mounting hole 2401 for mounting the duct connecting portion 21 is formed in the first surface 240a in the thickness direction of the body portion 24D. Two mounting holes 2401 are provided in the first surface 240a. A plurality of (here, two) screw holes 2402 are formed around each mounting hole 2401 on the first surface 240a. A recess 2403 is formed in the first surface 240a in a region including the mounting hole 2401 and two corresponding screw holes 2402. As shown in FIG. The recess 2403 is rectangular. A mounting hole 2401 and two corresponding threaded holes 2402 are in the bottom surface of the recess 2403 . Further, a support portion 2408 is formed around each mounting hole 2401 on the first surface 240a. The supporting portion 2408 and the lever 212 support the connecting portion 26D so as not to come into contact with it. The support portion 2408 has a tubular shape surrounding the mounting hole 2401 on the first surface 240a. The support portion 2408 is formed integrally with the first surface 240a of the body portion 24D. Support portion 2408 is lower than restricting portions 2485a and 2485b. A locking hole 2409 is provided in the first surface 240a in the thickness direction of the body portion 24D. Two locking holes 2409 are provided in the first surface 240a. The two locking holes 2409 are positioned corresponding to the connecting hole 2486a of the first wall 248a and the connecting hole 2486b of the second wall 248b.

The connecting portion 26D is used to connect the connection device 10D to the wiring duct 40 using the string-like body 93 (see FIGS. 3 and 4). The connecting portion 26D is made of metal. As an example, the connecting portion 26D can be formed by punching and bending a metal plate. The connecting portion 26D is a separate member from the body portion 24D and is fixed to the body portion 24D. The connecting portion 26D has a connecting hole 26a for connection with the string-like body 93. As shown in FIG. More specifically, the connecting portion 26</b>D has a flat portion 262 , a projecting portion 263 and a locking portion 264 . The flat plate portion 262 has a rectangular plate shape as a whole. Also, the flat plate portion 262 has a size that fits in the concave portion 2403 of the main body portion 24D. Here, the depth of recess 2403 is smaller than the thickness of flat plate portion 262 . The flat plate portion 262 has an opening 262a. The opening 262a is provided to expose the mounting hole 2401 and the support portion 2408. As shown in FIG. In addition, the flat plate portion 262 has a plurality of (here, two) holes 262b. The hole 262b is used to fix the connecting portion 26D to the main body portion 24D with a screw S14. Further, the connecting portion 26D has a locking projection 262c. The locking protrusion 262c is formed on the flat plate portion 262 so as to fit into the locking hole 2121 of the lever 212 of the duct connection portion 21 when the lever 212 is at a predetermined position. The protruding portion 263 protrudes from the flat plate portion 262 in a direction away from one surface (first surface 240a) of the main body portion 24D. The protruding portion 263 protrudes from one longitudinal end of the flat plate portion 262 . The projecting portion 263 is plate-shaped. Here, the connecting hole 26 a is provided in the projecting portion 263 . As a result, the projecting portion 263 appears to be U-shaped. Since the connecting hole 26a is provided in the projecting portion 263, the connecting device 10D and the wiring duct 40 can be easily connected by the string-like body 93. As shown in FIG. The locking portion 264 extends along the length direction of the flat plate portion 262 from the one longitudinal end of the flat plate portion 262 . The locking portion 264 has a rectangular plate shape.

As shown in FIG. 26, the connecting portion 26D is arranged in the concave portion 2403 of the main body portion 24D, and the supporting portion 2408 provided on the main body portion 24D is exposed from the opening 262a of the connecting portion 26D. At this time, the locking portion 264 is inserted into the body portion 24D from the locking hole 2409 of the body portion 24D. The connecting portion 26D is fixed to the main body portion 24D by connecting the screw S14 through the hole 262b of the flat plate portion 262 to the screw hole 2402 of the main body portion 24D. Since the connection portion 26D can be fixed to the main body portion 24D by the flat plate portion 262 in this way, the strength of fixing the connection portion 26D to the main body portion 24D can be improved. Further, the engaging portion 264 of the connecting portion 26D enters the body portion 24D through the engaging hole 2409. As shown in FIG. This also improves the strength of fixing the connecting portion 26D to the main body portion 24D. Here, in the connecting portion 26D corresponding to the first connecting portion 21a, as shown in FIG. 26, the connecting hole 26a faces the connecting hole 2486b of the second wall 248b. That is, the string-like body 93 is connected to the connecting device 10D using the connecting holes 26a and 2486b. Also, in the connecting portion 26D corresponding to the second connecting portion 21b, the connecting hole 26a is connected to the connecting hole 2486a of the first wall 248a. That is, the string-like body 93 is connected to the connecting device 10D using the connecting holes 26a and 2486b. Thereby, the string-like body 93 is directly connected to both the connecting portion 26D and the main body portion 24D. Therefore, the strength of connection of the string-like body 93 to the connection device 10D can be improved.

Also in this modified example, the first and second coupling portions 21a and 21b of the duct connection portion 21 are attached to the body portion 24D using the attachment holes 2401 of the body portion 24D. That is, each of the first coupling portion 21a and the second coupling portion 21b is inserted into the mounting hole 2401 such that the protrusion 211 can rotate about its central axis. Here, there is a support portion 2408 around the attachment hole 2401 in the body portion 24D. As shown in FIG. 26, the flat plate portion 262 of the connecting portion 26D is between the first surface 240a and the lever 212. As shown in FIG. The support portion 2408 supports the lever 212 so that it does not come into contact with the connecting portion 26D (the flat plate portion 262).

The connection device 10D is attached to the wiring duct 40 as follows. First, if necessary, the lever 212 is operated to set the first and second coupling portions 21a and 21b to the first position as indicated by the two-dot chain line in FIG. In this state, the first and second coupling portions 21 a and 21 b are inserted into the case 42 through the opening 43 of the wiring duct 40 . At this time, if the connection device 10D is positioned incorrectly with respect to the wiring duct 40, the duct facing surface 2411 of the base portion 241 hits the tip of the projection 44, so that the wiring duct 40 of the first and second coupling portions 21a and 21b is not moved. is blocked from being inserted into the case 42 . Therefore, erroneous connection can be prevented. In other words, it is possible to reduce the possibility of attaching the connection device 10D to the wiring duct 40 in a wrong manner. On the other hand, if the connection device 10</b>D is positioned correctly with respect to the wiring duct 40 , the duct-facing surface 2411 of the base 241 does not contact the tip of the projection 44 . Therefore, the insertion of the wiring duct 40 into the case 42 of the first and second coupling portions 21a and 21b is not hindered. Therefore, the first and second coupling portions 21 a and 21 b can be inserted into the case 42 of the wiring duct 40 .

After inserting the first and second coupling portions 21a and 21b into the case 42 through the opening 43 of the wiring duct 40, the lever 212 is operated to move the first and second coupling portions 21a and 21b from the first position to the second position. 2 position. As a result, as shown by solid lines in FIG. 27, the pair of protrusions 213, 213 are physically attached to both edges of the opening 43 of the case 42 of the wiring duct 40 in each of the first and second coupling portions 21a, 21b. supported by Also, in the first coupling portion 21a, the first, second and third terminals 214a, 214b and 214c are electrically connected to the first, second and third conductors 41a, 41b and 41c of the wiring duct 40, respectively. . Thereby, the duct connection portion 21 is physically attached to the wiring duct 40 and electrically connected thereto.

The connection device 10D has first and second wall portions 2480a and 2480b projecting from the center of the duct facing surface 2411 facing the wiring duct 40. As shown in FIG. When the main body 24D is held by the wiring duct 40 at the duct connecting portion 21, the first and second wall portions 2480a and 2480b face the first and second side surfaces 4211 and 4221 of the wiring duct 40, respectively. Therefore, even when the body portion 24D swings along the width direction of the wiring duct 40, at least one of the first and second wall portions 2480a and 2480b hits the wiring duct 40, thereby reducing the swinging of the body portion 24D. . Therefore, according to the connection device 10D, the stability of the mechanical connection with the wiring duct 40 can be improved.

Further, the connection device 10D has a first contact portion (first projection 244a) and a second contact portion (second projection 244b). Therefore, even when the body portion 24D swings along the width direction of the wiring duct 40, at least one of the first and second contact portions is in contact with the wiring duct 40, so that the swinging of the body portion 24D is reduced. Therefore, according to the connection device 10D, the stability of the mechanical connection with the wiring duct 40 can be improved.

Furthermore, the connection device 10D has a connection portion 26D having a connection hole 26a for connection with the string-like body 93. As shown in FIG. Therefore, the connection device 10D can be connected to the wiring duct 40 using the string-like body 93, and even when the duct connection portion 21 of the connection device 10D is detached from the wiring duct 40, the connection device 10D can be connected to the string-like body 93. is suspended from the wiring duct 40. Therefore, it is possible to reduce the possibility that the connection device 10D will fall. In particular, the connecting portion 26D is a separate member from the body portion 24D and is fixed to the body portion 24D. Therefore, the connecting portion 26D can be made of a material having a higher strength than the main body portion 24D. Therefore, when the connection device 10D is suspended from the wiring duct 40 by the string-like body 93, the possibility that the connecting portion 26D will be damaged and the connection device 10D will fall can be reduced.

Further, the connection device 10D includes a pair of extensions 2484a, 2484a and a pair of extensions 2484b, 2484b. These extensions 2484a and 2484b can protect the first and second joints 21a and 21b. For example, it is possible to reduce the possibility that the first and second coupling portions 21 a and 21 b are unintentionally hit by an object and rotate, thereby releasing the coupling with the wiring duct 40 . Moreover, since the first and second coupling portions 21a and 21b are hidden by the extension portions 2484a and 2484b, the appearance (design) of the connection device 10D can be improved.

(2.5) Other Modifications In one modification, as shown in FIG. 28, the body portion 24 may further include a first rib 249a and a second rib 249b. In FIG. 28, a plurality of (here, three) first ribs 249a and a plurality of (here, three) second ribs 249b are provided.

The first rib 249a protrudes from a surface (inner surface) 2422a of the first wall portion 242a on the duct facing surface 2411 side. Furthermore, the three first ribs 249a are arranged at equal intervals along the length direction of the first wall portion 242a. The first rib 249a is arranged side by side with the first reinforcing portion 243a in the width direction (horizontal direction in FIG. 28) of the first wall portion 242a. In other words, the first reinforcing portion 243a also serves to reinforce the first rib 249a.

As shown in FIG. 29, the first rib 249a extends in the height direction of the first wall portion 242a. Here, the angle of the first rib 249a with respect to the duct facing surface 2411 is greater than the angle of the inner side surface 2422a of the first wall portion 242a with respect to the duct facing surface 2411 . In other words, the first rib 249a gets closer to the first side surface 4211 of the wiring duct 40 than the first wall portion 242a as it separates from the duct facing surface 2411 . However, the angle of the first rib 249a with respect to the duct facing surface 2411 is 90° or less.

The second rib 249b protrudes from a surface (inner surface) 2422b of the second wall portion 242b on the duct facing surface 2411 side. Furthermore, the three second ribs 249b are arranged at equal intervals along the length direction of the second wall portion 242b. The second rib 249b is arranged side by side with the second reinforcing portion 243b in the width direction (horizontal direction in FIG. 28) of the second wall portion 242b. That is, the second reinforcing portion 243b also helps reinforce the second rib 249b.

As shown in FIG. 29, the second rib 249b extends in the height direction of the second wall portion 242b. Here, the angle of the second rib 249b with respect to the duct facing surface 2411 is greater than the angle of the inner side surface 2422b of the second wall portion 242b with respect to the duct facing surface 2411. In other words, the second rib 249b gets closer to the second side surface 4221 of the wiring duct 40 than the second wall portion 242b as it separates from the duct facing surface 2411 . However, the angle of the second rib 249b with respect to the duct facing surface 2411 is 90° or less.

The connection device 10 has first and second wall portions 242 a and 242 b projecting from both sides of a duct facing surface 2411 facing the wiring duct 40 . 28 and 29, the connection device 10 has first and second ribs 249a, 249b projecting from the first and wall portions 242a, 242b toward the wiring duct 40. As shown in FIGS. Therefore, when the body portion 24 is held by the wiring duct 40 at the duct connection portion 21, the first and second wall portions 242a and 242b and the first and second ribs 249a and 249b extend in the width direction of the wiring duct 40. They face the first and second side surfaces 4211 and 4221, respectively. Even when the body portion 24 swings along the width direction of the wiring duct 40, the first wall portion 242a hits the wiring duct 40 via the first rib 249a, or the second wall portion 242b hits the wiring duct 40 via the second rib 249b. It hits the wiring duct 40 . As a result, shaking of the main body portion 24 is reduced.

Furthermore, the first rib 249a approaches the first side surface 4211 of the wiring duct 40 more than the first wall portion 242a as it separates from the duct facing surface 2411 . Furthermore, the second rib 249b approaches the second side surface 4221 of the wiring duct 40 more than the second wall portion 242b as it separates from the duct-facing surface 2411 . Therefore, the space between the first wall portion 242a and the second wall portion 242b can be widened. This facilitates attachment of the wiring duct 40 to the connection device 10 . In addition, the first and second ribs 249a and 249b make it easier for the first wall portion 242a and the second wall portion 242b to contact the wiring duct 40 indirectly. This makes it easier to reduce the shaking of the body portion 24 and improves the stability of the mechanical connection with the wiring duct 40 . That is, the stability of the mechanical connection with the wiring duct 40 can be improved while facilitating the attachment of the wiring duct 40 to the connection device 10 .

Such first ribs 249a and second ribs 249b can also be applied to the connection device 10B of the second modification and the connection device 10D of the fourth modification. Note that the number of first ribs 249a does not have to be two or more. Also, the number of the second ribs 249b does not have to be two or more. Also, the first rib 249a and the second rib 249b may not be provided at the same time, and one of the first rib 249a and the second rib 249b may be provided.

Also, the locking projection 260c does not necessarily have to be provided on the connecting portion 26. As shown in FIG. For example, the locking protrusion 260c may be provided on the main body portion 24 . Also, the locking projection 260c can be omitted. This point is the same for the locking projection 262c.

In one variation, the support portion 27 does not necessarily have to be separate from the body portion 24 . The support portion 27 may be formed integrally with the body portion 24 . Moreover, the support part 27 can be omitted.

In one modification, the first surface 240a includes a base portion 241, first and second wall portions 242a and 242b, a plurality of first and second reinforcing portions 243a and 243b, and a plurality of first and second projections. 244a, 244b and all of the plurality of restricting portions 245 may not be provided. Also, these may be separate from the body portion 24 .

In a modified example, the platform 241 may not be rectangular in plan view, but may be polygonal or circular. Further, the duct facing surface 2411 may be a part of the upper surface of the base portion 241 instead of the entire upper surface. Further, the base portion 241 may not have the step 2412 on the duct facing surface 2411 .

In a modified example, the first and second walls 242a and 242b are arranged such that when the main body 24 is held by the wiring duct 40 at the duct connecting portion 21, the first and second side surfaces 4211 and 4211 in the width direction of the wiring duct 40, respectively. 4221 may be directly contacted. In addition, not all of the first and second walls 242a and 242b may face each other in the width direction of the duct facing surface 2411, and the first and second walls 242a and 242b may face the duct. They do not necessarily have to face each other in the width direction of the surface 2411 . In short, the first and second walls 242a and 242b should only protrude from one surface (first surface 240a) of the main body 24 on the side of the wiring duct 40 and be positioned on both sides of the duct facing surface 2411 . Each of the first and second walls 242a and 242b is composed of a plurality of small walls aligned in the length direction of the wiring duct 40 when the main body 24 is held by the wiring duct 40 at the duct connection portion 21. may have been Also, the height of each of the first and second wall portions 242a and 242b is not particularly limited. For example, the heights of the first and second walls 242a and 242b are such that, in the attached state, the center of the wiring duct 40 is the first and second walls 242a in the thickness direction of the wiring duct 40 (vertical direction in FIG. 9). , 242 b and the duct facing surface 2411 . This point also applies to the first and second wall portions 2480a and 2480b.

In a modified example, the number of first and second reinforcing portions 243a, 243b is not limited to five as in the above embodiment. The numbers of the first and second reinforcing parts 243a and 243b may each be one or more. In a modified example, the structure of the first and second reinforcing parts 243a and 243b is not limited to the structure of the above embodiment. The first and second reinforcing portions 243a and 243b may have a structure capable of reinforcing the first and second wall portions 242a and 242b.

In one modification, the heights of the first protrusion 244a and the second protrusion 244b are not particularly limited. Therefore, the height of the first contact portion (first projection 244 a ) is the same as the dimension between the pair of projections 213 of the first coupling portion 21 a or the second coupling portion 21 b and the first contact portion of the wiring duct 40 . It does not have to be smaller than the thickness of one portion 424 .
