Furthermore, if the device 50 is a digital signage, the management device 60 can cause the device 50 to display information. The management device 60 can be realized by, for example, a personal computer (desktop computer, laptop computer, etc.). Note that the management device 60 may be, for example, a mobile information terminal such as a smartphone or a tablet terminal.

Next, the connection device 10 will be explained. The connection device 10 is a device for connecting a device 50 to the wiring duct 40. In other words, the connecting device 10 functions as a plug for connecting the device 50 to the wiring duct 40.

FIG. 1 shows a block diagram of the connection device 10, and FIG. 2 is a perspective view of the connection device 10. As shown in FIGS. 1 and 2, the connection device 10 includes a housing 20 and a circuit block 30 housed in the housing 20.

As shown in FIG. 1, the housing 20 includes a duct connection section 21, a device connection section 22, and an auxiliary power supply section 23. Furthermore, the housing 20 includes a housing section 24 and a holding section 25, as shown in FIGS. 2 to 4.

The accommodating section 24 is a box and is configured to accommodate the circuit block 30. As shown in FIGS. 2 to 4, the accommodating portion 24 is shaped like a rectangular parallelepiped box. The accommodating portion 24 has a length, a width, and a thickness.

Further, the housing section 24 is provided with a duct connection section 21, a device connection section 22, and an auxiliary power supply section 23.

The duct connection part 21 is used to attach the connection device 10 to the wiring duct 40. The duct connecting portion 21 is provided on the first surface (the upper surface in FIG. 2) of the housing portion 24 in the thickness direction. The duct connection section 21 includes first and second coupling sections 21a and 21b. The first and second coupling parts 21a and 21b are arranged on both sides of the first surface of the housing part 24 in the thickness direction. In particular, in the present embodiment, the first and second coupling parts 21a and 21b are located on both sides of the housing part 24 in the length direction on the first surface in the thickness direction of the housing part 24, and In the center of the direction.

The first and second coupling parts 21a and 21b each include a protrusion 211, a lever 212, and a pair of protrusions 213, 213. The protrusion 211 protrudes from the first surface of the housing portion 24 in the thickness direction. The protrusion 211 has a cylindrical shape and is rotatable around its central axis. Further, the protrusion 211 itself has a size that allows it to pass through the opening 43 of the case 42. The lever 212 is a member for rotating the protrusion 211 around its central axis. The lever 212 protrudes from the protrusion 211 in a direction intersecting its central axis. A pair of protrusions 213, 213 protrude from the protrusion 211 on both sides. The width of the pair of protrusions 213, 213 is less than or equal to the diameter of the protrusion 211.

Moreover, the first coupling portion 21a further includes first and second terminals 214a and 214b. The first and second terminals 214a and 214b are electrically connected to the first and second conductors 41a and 41b of the wiring duct 40, respectively. In this embodiment, the first and second terminals 214a and 214b are associated with the first and second conductors 41a and 41b of the wiring duct 40, respectively. Therefore, connecting the first and second terminals 214a and 214b to the first and second conductors 41a and 41b, respectively, is a positive connection, but connecting the first and second terminals 214a and 214b to the second and first conductors 41b , 41a would be an incorrect connection. The first and second terminals 214a and 214b protrude from the protrusion 211 on both sides similarly to the pair of protrusions 213 and 213. The first and second terminals 214a, 214b are located closer to the tip of the protrusion 211 than the pair of protrusions 213, 213, and overlap with the pair of protrusions 213, 213 when viewed from the direction along the central axis of the protrusion 211. are doing.

The first and second coupling parts 21a and 21b are rotatable between a first position (first rotational position) and a second position (second rotational position) by operating the lever 212. The first position is a position where the pair of protrusions 213, 213 are lined up in the length direction of the accommodating part 24. The second position is a position where the pair of protrusions 213, 213 are lined up in the width direction of the accommodating portion 24. For example, in FIG. 2, the first coupling part 21a is in the second position and the second coupling part 21b is in the first position. Further, in FIG. 3, both the first and second coupling portions 21a and 21b are in the second position. Moreover, in FIG. 5, the first coupling part 21a in the first position is shown by a solid line, and the first coupling part 21a in the second position is shown by a two-dot chain line. That is, the first and second coupling parts 21a and 21b can pass through the opening 43 in the first position, but cannot pass through the opening 43 in the second position.

The device connection section 22 is a part for connecting with the device 50. In this embodiment, the device connection section 22 is connected to the device 50 via a connection line 80. The device connection unit 22 is, for example, a port compatible with Ethernet. In particular, the device connection section 22 also supports Power over Ethernet (PoE). In this embodiment, as shown in FIG. 2, the device connection section 22 is provided on a side surface of the housing section 24 (particularly on one side surface in the longitudinal direction of the housing section 24).

The auxiliary power supply unit 23 is a part for supplying the first power conveyed by the wiring duct 40. The auxiliary power supply section 23 is a connector equipped with a terminal for supplying power. As an example, the auxiliary power supply section 23 may be an outlet (for example, an outlet for a plug) used for feeding commercial AC power. In this embodiment, the auxiliary power supply section 23 is provided on a side surface of the housing section 24 (particularly on a side surface opposite to the side surface on which the device connection section 22 is located).

Further, the accommodating portion 24 has a rib 240 on the first surface (the upper surface in FIG. 2) of the accommodating portion 24 in the thickness direction. When the connection device 10 (particularly the accommodating portion 24) is in the correct position with respect to the wiring duct 40, the rib 240 does not come into contact with the tip (lower end in FIG. 5) of the protrusion 44 of the wiring duct 40. On the other hand, if the connection device 10 (particularly the accommodating portion 24) is in the wrong position with respect to the wiring duct 40, the rib 240 comes into contact with the tip (lower end in FIG. 5) of the protrusion 44 of the wiring duct 40. Here, if the rib 240 is in contact with the protrusion 44, the rib 240 and the protrusion 44 will get in the way, and even if the first and second coupling parts 21a and 21b are in the first position, they will not be inserted into the opening 43 of the wiring duct 40. Can not. In this embodiment, the rib 240 has a rectangular parallelepiped shape and has a step 241 so as not to come into contact with the protrusion 44 when the accommodating portion 24 is in the correct position with respect to the wiring duct 40. The correct position of the connection device 10 with respect to the wiring duct 40 is the position where the first and second terminals 214a, 214b are connected to the first and second conductors 41a, 41b, respectively. The incorrect position of the connection device 10 with respect to the wiring duct 40 is a position where an incorrect connection occurs in which the first and second terminals 214a, 214b are connected to the second and first conductors 41b, 41a, respectively.

The connection device 10 including the duct connection portion 21 as described above is attached to the wiring duct 40 in the following manner. First, the lever 212 is operated as necessary to bring the first and second coupling parts 21a and 21b into the first position. In this state, the first and second coupling parts 21a and 21b are inserted into the case 42 through the opening 43 of the wiring duct 40. At this time, if the connecting device 10 is in the wrong position with respect to the wiring duct 40, the rib 240 will hit the tip of the protrusion 44, so the first and second coupling parts 21a and 21b will not enter the case 42 of the wiring duct 40. Insertion is inhibited. Therefore, erroneous connections can be prevented. In other words, the possibility of attaching the connection device 10 to the wiring duct 40 in an incorrect manner can be reduced. On the other hand, if the connecting device 10 is in the correct position with respect to the wiring duct 40, the rib 240 will not come into contact with the tip of the protrusion 44. Therefore, insertion of the first and second coupling parts 21a and 21b into the case 42 of the wiring duct 40 is not hindered. Therefore, the first and second coupling parts 21a and 21b can be inserted into the case 42 of the wiring duct 40.

After inserting the first and second coupling parts 21a and 21b into the case 42 through the opening 43 of the wiring duct 40, operate the lever 212 to move the first and second coupling parts 21a and 21b from the first position to the second position. Set to 2nd position. As a result, as shown by the two-dot chain line in FIG. Physically supported. Further, in the first coupling portion 21a, the first and second terminals 214a and 214b are electrically connected to the first and second conductors 41a and 41b of the wiring duct 40, respectively. Thereby, the duct connection part 21 is physically attached to the wiring duct 40 and electrically connected. In particular, in the present embodiment, the duct connection section 21 is physically attached to the wiring duct 40 at two locations (first and second coupling sections 21a and 21b). Therefore, the connection device 10 can be more firmly attached to the wiring duct 40, and furthermore, heavier equipment 50 can be attached.

The holding section 25 is a member for physically holding the device 50. In this embodiment, the holding section 25 is separate from the housing section 24 and is physically attached to the housing section 24 .

The holding part 25 includes a first holder 26 and a second holder 27, as shown in FIGS. 2 to 4. The first holder 26 and the second holder 27 are made of a strong material such as a metal material.

The first holder 26 includes a rod 261, a first attachment part 262, and a second attachment part 263, as shown in FIGS. 3 and 4. Rod 261 has a cylindrical shape. The first mounting portion 262 is a portion that becomes a pedestal on which the device 50 is fixed. The first attachment portion 262 is provided at the first end (lower end in FIG. 4) of the rod 261. The first attachment part 262 is disc-shaped, and has a fixing part 262a, which is a screw used for fixing the device 50, in the center. The second attachment part 263 is a part for attaching the first holder 26 to the accommodating part 24. The second attachment part 263 is provided at the second end (the upper end in FIG. 4) of the rod 261. The second attachment portion 263 has a plate shape (in this embodiment, a disk shape).

The second holder 27 includes a base 271 and a plurality of (four in the illustrated example) arm portions 272. The base 271 is a part for fixing the second holder 27 to the accommodating part 24. The base 271 has a plate shape (in this embodiment, a rectangular plate shape). The base 271 is attached to the housing portion 24 by screws or the like. Each arm portion 272 protrudes from the side of the base 271 toward the first holder 26 side. The arm portion 272 is coupled to the first holder 26 at its distal end side.

In the holding part 25, the second holder 27 is attached to the holding part 24 by fixing the base 271 to the second surface (lower surface in FIG. 4) of the holding part 24 in the thickness direction using screws or the like. Here, the second holder 27 is located at the center of the second surface of the accommodating portion 24 in the thickness direction. Further, the first holder 26 is attached to the second holder 27 by fixing the second attachment part 263 to the plurality of arm parts 272 of the second holder 27 by screwing or the like. Thereby, as shown in FIG. 2, the holding part 25 (the first holding tool 26 and the second holding tool 27) is attached to the accommodating part 24. According to the holding part 25, the device 50 can be fixed to the holding part 25 using the fixing part 262a.

As shown in FIG. 1, the circuit block 30 includes a first communication section 31, an output section 32, a processing section 33, a power supply section 34, a notification section 35, and an operation section 36.

The first communication unit 31 includes a communication interface compliant with power line carrier communication, and has a function of transmitting and receiving communication signals based on power line carrier communication. Note that various well-known standards can be adopted as the power line carrier communication, and for example, it is preferable to adopt high-speed power line communication (High Definition Power Line Communication). A communication interface conforming to such power line carrier communication may have a conventionally well-known configuration, so a 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 and 214b of the first coupling section 21a of the duct connection section 21. Therefore, by attaching the duct connection part 21 to the wiring duct 40, the first communication part 31 is electrically connected to the wiring duct 40 via the duct connection part 21. Therefore, the first communication unit 31 has a function (receiving function) of receiving a communication signal (first communication signal) by power line carrier communication from the wiring duct 40 through the duct connection unit 21. The first communication unit 31 also has a function (transmission function) of transmitting a communication signal (second communication signal) by power line carrier communication to the wiring duct 40 through the duct connection unit 21. That is, bidirectional communication by the first communication unit 31 is possible.

The output section 32 is an electric circuit including a second communication section 321 and a conversion section 322, as shown in FIG.

The second communication unit 321 is a circuit for communicating with the device 50 using a communication standard (communication protocol) different from power line carrier communication in accordance with the first communication signal received by the first communication unit 31.

In this way, the second communication section 321 communicates with the device 50 through the connection line 80 connected to the device connection section 22.

The converter 322 is a circuit that generates second power of a power standard different from the first power based on the first power acquired from the wiring duct 40 through the duct connection part 21 and supplies it to the device 50. As described above, the first power is AC power (for example, 60/50Hz, 100/200V commercial AC power), and the second power is power that complies with the PoE standard, for example, 48V DC power. It is electricity. Therefore, the conversion unit 322 may be configured by a power conversion circuit including an ACDC converter. As shown in FIG. 1, the conversion section 322 is connected to the device connection section 22. Therefore, the converting unit 322 outputs the second power having a different power standard from the first power to the device connecting unit 22. That is, the converting section 322 supplies the second power to the device 50 through the connection line 80 connected to the device connecting section 22 .

In the present embodiment, the output unit 32 complies with the Power over Ethernet standard, and functions as so-called power sourcing equipment. Furthermore, the power supply method is either a method of superimposing current on two pairs of connection lines 80 used for communication (Alternative A) or a method of supplying power using two unused pairs of connection wires 80 (Alternative B2). You can. That is, the output section 32 uses the device connection section 22 for communication with the device 50 and for supplying power to the device 50. Therefore, connection between the connection device 10 and the device 50 for communication and power supply can be easily performed.

The processing unit 33 is a control circuit that controls the operation of the connection device 10. The processing unit 33 can be realized, for example, by a computer system including one or more processors (microprocessors) and one or more memories. That is, one or more processors function as the processing unit 33 by executing one or more programs stored in one or more memories. In the present embodiment, the processing unit 33 converts the first communication signal received from the wiring duct 40 through the duct connection unit 21 into a signal of a communication standard (communication protocol) different from power line carrier communication by the second communication unit 321. It is configured to output as follows. Further, the processing unit 33 converts the signal received by the second communication unit 321 from the device 50 through the connection line 80 into a communication signal (second communication signal) conforming to power line carrier communication by the first communication unit 31. is configured to print. That is, the processing section 33 may have a function of simply relaying signals between the first communication section 31 and the second communication section 321. In addition, the processing unit 33 may have a function of controlling the device 50 according to the first communication signal received by the first communication unit 31. Further, the processing unit 33 may have a function of collecting information from the device 50 using the second communication unit 321 and sending the information from the first communication unit 31 to the management device 60 through the wiring duct 40.

The power supply section 34 is a circuit for supplying operating power to the processing section 33. In this embodiment, the power supply section 34 generates the power necessary for driving the processing section 33 using the output (second power) of the conversion section 322 of the output section 32 . The power supply section 34 may be a power supply circuit including one or more DC/DC converters. Such a power supply circuit may have a conventionally well-known configuration, so a detailed explanation will be omitted.

The notification section 35 may include one or more display devices. Examples of display devices include lamps such as light emitting diodes. Note that the notification unit 35 may include an electroacoustic transducer such as a speaker and a buzzer in addition to or in place of the display device. That is, the notification by the notification unit 35 is not limited to visual notification, but may be auditory notification. For example, the processing unit 33 may notify the status of the connection device 10 (whether the connection device 10 is operating normally or has stopped due to an abnormality) using the notification unit 35. Alternatively, the processing unit 33 may cause the notification unit 35 to make a notification according to the first communication signal received by the first communication unit 31.

The operation unit 36 is a circuit for changing and initializing settings of the connection device 10. The operation unit 36 may include, for example, one or more switches. Examples of the switch include conventionally known switches such as a dip switch, a slide switch, and a push switch. An example of changing the settings of the connection device 10 is master/slave switching.

Furthermore, the connection device 10 uses the converter 322 of the output unit 32 to generate second power of a different standard from the first power based on the first power acquired from the wiring duct 40 through the duct connection unit 21, and supplies the second power to the device 50. supply Therefore, according to the connection device 10, even if the device 50 has a power standard different from that of the wiring duct 40, communication and power supply using the wiring duct 40 can be performed.

Further, since the position of the connection device 10 on the wiring duct 40 can be easily changed, it is not necessary to accurately determine the position of the equipment 50 from the beginning when installing the equipment system. Therefore, installation of the equipment system becomes easier. In particular, in this embodiment, the connection device 10 includes a holding section 25 for holding the device 50. Therefore, by changing the position of the connection device 10 on the wiring duct 40, the position of the device 50 can also be changed. Therefore, the position of the device 50 can be easily changed. Further, the holding section 25 is separate from the housing section 24 and is physically attached to the housing section 24 . Therefore, when attaching the device 50 to the connection device 10, the holding portion 25 may be removed from the housing portion 24, the device 50 may be attached to the holding portion 25, and then the holding portion 25 may be attached to the housing portion 24. In this way, when attaching the device 50 to the connection device 10, there is no need to remove the connection device 10 itself from the wiring duct 40. Therefore, the work of attaching the device 50 to the connection device 10 becomes easier.

2. Modifications Embodiments of the present disclosure are not limited to the above embodiments. The embodiments described above can be modified in various ways depending on the design, etc., as long as the objects of the present disclosure can be achieved. Modifications of the above embodiment are listed below.

2.1 First Modification FIG. 6 and FIG. 7 show a connection device 10A of a first modification. The connecting device 10A has a housing 20A that is different from the housing 20 of the connecting device 10. The housing 20A includes a housing section 24A and a holding section 25A that are different from the housing section 24 and holding section 25 of the housing 20.

The accommodation section 24A is different from the accommodation section 24 in the location of the device connection section 22. As shown in FIG. 7, the device connection portion 22 is provided on the second surface (lower surface in FIG. 7) of the housing portion 24A in the thickness direction. In particular, the device connection section 22 is located at the center of the second surface of the housing section 24A in the thickness direction. Also in the accommodating part 24A, the holding part 25A is fixed to the central portion of the second surface in the thickness direction of the accommodating part 24A. Therefore, the holding portion 25A and the device connection portion 22 are on the same side of the housing 20A.

The holding portion 25A is separate from the accommodating portion 24A, and is physically attached to the accommodating portion 24A. The holding portion 25A includes a first holder 26A and a second holder 27A, as shown in FIGS. 6 and 7. The first holder 26A and the second holder 27A are made of a strong material such as a metal material. Like the first holder 26, the first holder 26A includes a rod 261, a first attachment part 262, and a second attachment part 263. Furthermore, the first holder 26A has a guide hole 264 through which the connection wire 80 is passed. The guide hole 264 is a hole that connects the center portion of the second attachment portion 263 and the side surface of the rod 261, as shown in FIG. Like the second holder 27, the second holder 27A includes a base 271 and a plurality of (four in the illustrated example) arm parts 272. Furthermore, the second holder 27A has an opening 273 through which the connection wire 80 is passed. The opening 273 is located in the central portion of the base 271, as shown in FIG. 7, and exposes the device connection portion 22. Therefore, the connection line 80 can be connected to the device connection section 22 through the opening 273.

In the connection device 10A, the holding section 25A and the device connection section 22 are on the same side of the housing 20A. Therefore, compared to the connection device 10, the distance between the device connection section 22 and the device 50 can be made closer. Therefore, the connection between the device connection section 22 and the device 50 using the connection line 80 becomes easy. Furthermore, in the first modification, the connection wire 80 can be connected to the device connection section 22 through the guide hole 264 of the holding section 25A. Thereby, the connection wire 80 can be protected by the holding portion 25A. Therefore, the possibility that an object gets caught on the connection line 80 and the connection line 80 is disconnected can be reduced. Furthermore, there is also the advantage that the connection line 80 becomes less noticeable.

2.2 Second Modification FIGS. 8 to 10 show a second modification of the connecting device 10B. As shown in FIG. 8, the connection device 10B includes a housing 20B and a circuit block 30 housed in the housing 20B.

The housing 20B includes a housing section 24B and a holding section 25B. Note that, unlike the holding part 25, the holding part 25B has only the second holding tool 27.

The accommodating portion 24B is a box and is configured to accommodate the circuit block 30. The housing portion 24B has a cylindrical box shape. Moreover, the center of the first surface (upper surface in FIG. 8) in the thickness direction of the accommodating portion 24B protrudes in a cylindrical shape. Further, the accommodating portion 24B is provided with a duct connecting portion 21B, a device connecting portion 22, and an auxiliary power feeding portion 23. The device connection section 22 and the auxiliary power supply section 23 are provided on the side surface of the housing section 24B. In addition, in FIG. 8, the auxiliary power supply section 23 is located on the opposite side to the device connection section 22 and is not visible.

The duct connection portion 21B is used to attach the connection device 10B to the wiring duct 40, as shown in FIGS. 9 and 10. The duct connecting portion 21B is provided on the first surface (the upper surface in FIG. 8) of the housing portion 24B in the thickness direction. The duct connection section 21B includes one coupling section 21c. The coupling portion 21c is located at the center of the first surface of the housing portion 24B in the thickness direction.

Like the first coupling part 21a, the coupling part 21c includes a protrusion 211, a pair of protrusions 213, 213, and first and second terminals 214a, 214b. However, unlike the first coupling part 21a, the coupling part 21c does not have the lever 212, and the protrusion 211 is not configured to be rotatable.

Further, the housing portion 24B further includes a rib 240B. The rib 240B is provided on the first surface of the accommodating portion 24B in the thickness direction. The rib 240B does not come into contact with the tip of the protrusion 44 of the wiring duct 40 when the connecting device 10B (particularly the accommodating portion 24B) is in the correct position with respect to the wiring duct 40. On the other hand, the rib 240B contacts the tip of the protrusion 44 of the wiring duct 40 when the connection device 10B (particularly the accommodating portion 24B) is in the wrong position with respect to the wiring duct 40. Here, if the rib 240B hits the tip of the protrusion 44, the rib 240B and the protrusion 44 will get in the way, making it impossible to insert the coupling part 21c into the opening 43 of the wiring duct 40. As shown in FIGS. 9 and 10, the rib 240B includes a guide portion 242 and first and second positioning portions 243 and 244. The guide portion 242 is located on the outer side of the accommodating portion 24B than the connecting portion 21c when viewed from the direction along the central axis of the connecting portion 21c. The guide portion 242 has an arc shape centered on the central axis of the coupling portion 21c. As an example, the central angle of the guide portion 242 is about 90 to 120 degrees. The first positioning part 243 protrudes from the first end of the guide part 242 toward the coupling part 21c. The first positioning portion 243 is a linear protrusion that extends in the direction in which the pair of protrusions 213, 213 of the coupling portion 21c are lined up. The second positioning part 244 protrudes from the second end of the guide part 242 toward the coupling part 21c. The second positioning portion 244 is a linear protrusion that extends in a direction perpendicular to the direction in which the pair of protrusions 213, 213 of the coupling portion 21c are lined up.

The connection device 10B is attached to the wiring duct 40 as follows. First, as shown in FIG. 9, the accommodating part 24B is aligned with respect to the wiring duct 40 so that the direction in which the pair of protrusions 213, 213 of the coupling part 21c are lined up is along the length direction of the wiring duct 40. In this state, the coupling portion 21c is inserted into the case 42 through the opening 43 of the wiring duct 40. At this time, if the connecting device 10B is in the wrong position with respect to the wiring duct 40, the rib 240B comes into contact with the tip of the protrusion 44. For example, if the housing portion 24B is at a position rotated 180 degrees around its central axis from the position shown in FIG. 9, the rib 240B will come into contact with the tip of the protrusion 44. In this case, insertion of the coupling portion 21c into the case 42 of the wiring duct 40 is inhibited. Therefore, erroneous connections can be prevented. In other words, the possibility of attaching the connecting device 10B to the wiring duct 40 in an incorrect manner can be reduced. On the other hand, if the connecting device 10B is in the correct position with respect to the wiring duct 40 (the position shown in FIG. 9), the rib 240B does not come into contact with the tip of the protrusion 44. Therefore, insertion of the coupling portion 21c into the case 42 of the wiring duct 40 is not hindered. Therefore, the coupling portion 21c can be inserted into the case 42 of the wiring duct 40.

After the coupling part 21c is inserted into the case 42 through the opening 43 of the wiring duct 40, the housing part 24B is inserted so that the direction in which the pair of protrusions 213, 213 of the coupling part 21c are lined up is orthogonal to the length direction of the wiring duct 40. rotate around its central axis. Specifically, in FIG. 9, the accommodating portion 24B is rotated in the direction indicated by arrow A10. As a result, as shown in FIG. 10, the pair of protrusions 213, 213 are physically supported by both edges of the opening 43 of the case 42 of the wiring duct 40 at the coupling portion 21c. Further, the first and second terminals 214a and 214b are electrically connected to the first and second conductors 41a and 41b of the wiring duct 40, respectively. Thereby, the duct connecting portion 21B is physically attached to the wiring duct 40 and electrically connected.

Note that when attempting to rotate the housing portion 24B from the position shown in FIG. 9 in the opposite direction of the arrow A10, the rib 240B (especially the first positioning portion 243) hits the side surface (the left side surface in FIG. 9) of the protrusion 44. Rotation of the housing portion 24B in the opposite direction can be prevented. Furthermore, when the housing section 24B is in the position shown in FIG. 10, the rib 240B (especially the second positioning section 244) hits the side surface of the protrusion 44 (the left side surface in FIG. 9), so that the housing section 24B may be rotated too much. can be prevented. Therefore, attachment of the connection device 10B to the wiring duct 40 becomes easy.

Further, the rib 240B does not contact the tip of the protrusion 44 but contacts the case 42 during a positive connection in which the first and second terminals 214a and 214b are connected to the first and second conductors 41a and 41b, respectively. . In FIGS. 9 and 10, the case 42 is contacted at the rib 240B. More specifically, the rib 240B contacts one surface 420 of the case 42 (see FIG. 4) with a flat surface at the tip. Therefore, when trying to rotate the accommodating part 24B, the accommodating part 24B can be brought into contact with the case 42. This makes it easier to rotate the accommodating portion 24B with respect to the case 42. In other words, the rib 240B can be used as a guide when attaching the connecting device 10B to the wiring duct 40, making it easier to attach the connecting device 10B to the wiring duct 40.

2.3 Third Modified Example FIG. 11 shows a third modified example of a connecting device 10C. The connecting device 10C has a housing 20C that is different from the housing 20 of the connecting device 10. The housing 20C includes a housing part 24C and a holding part 25C that are different from the housing part 24 and the holding part 25 of the housing 20.

The accommodating portion 24C is a box and is configured to accommodate the circuit block 30. The housing portion 24C has a flat box shape, as shown in FIGS. 11 to 13. Further, the accommodating portion 24C is square in plan view. The housing portion 24C has a first surface (upper surface in FIGS. 11 to 13) and a second surface (lower surface in FIGS. 11 to 13) in the thickness direction. The second surface (lower surface in FIG. 11) in the thickness direction of the accommodating portion 24C is a mounting surface 245 for physically attaching the holding portion 25C. As shown in FIG. 12, four screw holes 245a are formed in the mounting surface 245. The four screw holes 245a are located at four-fold rotational symmetry with respect to the center of the mounting surface 245. Further, the housing portion 24C has an outer circumferential surface 246 surrounding the mounting surface 245. The outer peripheral surface 246 includes four outer surfaces 246a to 246d. The outer surfaces 246a and 246c are opposite surfaces, and the outer surfaces 246b and 246d are opposite surfaces.

Further, as shown in FIG. 12, the accommodating portion 24C has a protrusion (first positioning portion) 247 on the mounting surface 245. The protruding portion 247 protrudes from the edge of the mounting surface 245 along the thickness of the housing portion 24C. In particular, the protruding portion 247 protrudes from the edge of the mounting surface 245 toward the holding portion 25C so as to surround the mounting surface 245. The protrusion 247 has a rectangular frame shape in plan view.

The accommodating portion 24C is provided with a duct connecting portion 21, a device connecting portion 22, and an auxiliary power feeding portion 23. The first and second coupling parts 21a and 21b of the duct connection part 21 are provided on the first surface (the upper surface in FIG. 11) of the housing part 24C in the thickness direction. A connector 91 of a connection line 90 with the device 50 is connected to the device connection section 22 . In this modification, the device connection section 22 is a modular jack. The device connection portion 22 is located on an outer surface different from the mounting surface 245 in the housing portion 24C. More specifically, the device connection portion 22 is on the outer circumferential surface 246. In particular, the device connection portion 22 is provided on an outer surface 246a that is a part of the outer peripheral surface 246 of the housing portion 24C. In other words, the device connection section 22 only needs to be in a position where the connection wire 90 can be connected in the accommodation section 24C even when the holding section 25C is attached to the accommodation section 24C. The auxiliary power supply section 23 is provided on an outer surface 246c that is a part of the outer peripheral surface 246 of the housing section 24C. Furthermore, the operating section 36 is exposed on the outer surface 246b of the housing section 24C. Note that the device connection section 22 may have a lid (shutter) that can be opened and closed. Furthermore, the housing 20C may include a lid that covers the device connection section 22. Even in this case, the device connection portion 22 is still located on the outer surface of the housing portion 24C.

As shown in FIGS. 12 and 13, the holding portion 25C is separate from the accommodating portion 24C, and is physically attached to the mounting surface 245 of the accommodating portion 24C. As shown in FIGS. 12, 13, and 14, the holding portion 25C includes a main body 28C and a plurality of (here, eight) fittings 29C. Here, each fixture 29C is a nut. In particular, each fixture 29C is a metal nut.

The main body 28C is a molded product made of an insulating resin material. The main body 28C includes a mounting plate 280, a peripheral wall 281, a plurality of (here, four) bosses 282, and a plurality of (here, eight) holders 283.

The mounting plate 280 is a part to which the device 50 is attached. The mounting plate 280 has a rectangular shape (particularly a square shape) in plan view. The mounting plate 280 has an opening (first opening) 280a. The opening 280a is used to pass the connection wire 90 (see FIG. 13) for connecting the device 50 to the device connection section 22. Opening 280a is located at the center of mounting plate 280. Further, the opening 280a has a generally rectangular shape and is approximately 1/9 the size of the mounting plate 280.

The peripheral wall 281 protrudes from the edge of the mounting plate 280 along the thickness of the mounting plate 280. In particular, the peripheral wall 281 protrudes from the edge of the mounting plate 280 toward the housing portion 24C so as to surround the mounting plate 280. The peripheral wall 281 has a rectangular frame shape in plan view. The peripheral wall 281 has four side walls 281a to 281d. Among the four side walls 281a to 281d, side walls 281a and 281c face each other, and side walls 281b and 281d face each other. Further, the peripheral wall 281 has an opening (second opening) 281e. The opening 281e is used to pass the connection wire 90 (see FIG. 13) for connecting the device 50 to the device connection section 22. Opening 281e is in side wall 281a. Further, the opening 281e has a generally rectangular shape. The opening 281e has a cutout shape, and the side opposite to the mounting plate 280 is open. Further, the tip of the peripheral wall 281 constitutes a protrusion (second positioning portion) 281f. The protruding portion 281f has a rectangular frame shape and protrudes from the tips of the four side walls 281a to 281d of the peripheral wall 281 (excluding the portion corresponding to the opening 281e). As shown in FIG. 15, the protrusion 281f is formed to fit into the protrusion 247 of the accommodating part 24C. More specifically, the tip (protrusion 281f) of the peripheral wall 281 fits inside the protrusion 247 of the mounting surface 245 of the housing portion 24C. In this way, the accommodating portion 24C has a structure (the protrusion 247) in which the tip (the protrusion 281f) of the peripheral wall 281 fits into the attachment surface 245. However, the extent to which the tip of the peripheral wall 281 fits into the protrusion 247 of the mounting surface 245 may be such that the holding portion 25C can be positioned with respect to the accommodating portion 24C. In other words, it is not necessary to firmly fix the holding portion 25C to the accommodating portion 24C by fitting the tip of the peripheral wall 281 into the protrusion 247 of the mounting surface 245. Further, as shown in FIG. 12, the outer surface of the projection 281f is closer to the center of the peripheral wall 281 than the outer surfaces of the corresponding side walls 281a to 281d. As a result, the outer circumferential surface of the peripheral wall 281 is flush with the outer circumferential surface 246 surrounding the mounting surface 245 of the housing portion 24C.

A plurality of (here, four) bosses 282 are used to attach the holding portion 25C to the housing portion 24C with screws 500. Four bosses 282 are provided on the mounting plate 280, as shown in FIG. The four bosses 282 protrude from the mounting plate 280 toward the housing portion 24C. Each boss 282 is cylindrical. Each boss 282 is open on the mounting plate 280 side, but is closed on the opposite side from the mounting plate 280. However, in each boss 282, a hole 282a through which the shaft of the screw 500 passes is provided on the side opposite to the mounting plate 280. The four bosses 282 are located at four-fold rotational symmetry with respect to the center of the mounting plate 280, as shown in FIG. More specifically, the four bosses 282 are located near the center of each of the four side walls 281a to 281d of the peripheral wall 281.

The plurality of (here, eight) holders 283 are parts for holding a plurality of (here, eight) fixtures 29C, respectively. Eight holders 283 are provided on the mounting plate 280, as shown in FIG. The eight holders 283 protrude from the mounting plate 280 toward the housing portion 24C. Each holder 283 has a cylindrical shape. Each holder 283 is open on the side opposite to the mounting plate 280, but is closed on the side of the mounting plate 280. However, in each holder 283, a hole 283a is provided on the mounting plate 280 side, through which the shaft of a screw for attaching the device 50 passes. Eight fixtures 29C are arranged in the eight holders 283, respectively. In some cases, the fixture 29C is fixed to the holder 283 by thermocompression bonding or the like. The eight holders 283 are located at two-fold rotationally symmetrical positions with respect to the center of the mounting plate 280. More specifically, four of the eight holders 283 are between the side wall 281a and the opening 280a, and the remaining four are between the side wall 281c and the opening 280a.

The holding portion 25C is physically attached to the mounting surface 245 so that the mounting plate 280 faces the mounting surface 245 (see FIGS. 12 and 13). More specifically, by screwing the screws 500 into the four screw holes 245a of the accommodating part 24C through the holes 282a of the four bosses 282 of the holder 25C, the holder 25C is physically attached to the mounting surface 245 of the accommodating part 24C. It is attached. When the holding portion 25C is attached to the accommodating portion 24C, as shown in FIG. 15, the tip of the peripheral wall 281 (the protruding portion 281f) fits inside the protruding portion 247 of the accommodating portion 24C. This stabilizes the connection between the holding part 25C and the accommodating part 24C. Further, the outer circumferential surface of the peripheral wall 281 is flush with the outer circumferential surface 246 surrounding the mounting surface 245 of the housing portion 24C. This also stabilizes the connection between the accommodating portion 24C and the holding portion 25C.

To attach the device 50 to the holding portion 25C, screws may be fixed to the mounting tool 29C through the holes of the device 50 and the holes 283a of the holder 283. Furthermore, when connecting the device 50 and the device connection portion 22 with the connection wire 90, the connection wire 90 is passed through the opening 280a of the mounting plate 280 and the opening 281e of the peripheral wall 281, and the connector 91 of the connection wire 90 is connected to the device connection portion 22. All you have to do is connect. In this modification, a portion of the connection wire 90 can be accommodated in the holding portion 25C. This reduces the exposure of the connection line 90, so that the connection line 90 can be protected. Furthermore, the appearance of the device 50 when attached to the connection device 10C is improved.

Here, the holding part 25C can be attached to the accommodating part 24C at a plurality of positions. Any one of the plurality of positions is a position rotated around a rotation axis along the direction in which the mounting surface 245 of the accommodating part 24C and the mounting plate 280 of the holding part 25C face each other with respect to the rest of the plurality of positions. It is. Specifically, since the four bosses 282 and the four screw holes 245a are each arranged four-fold rotationally symmetrically, the holding part 25C can be attached to the accommodating part 24C at four positions.

Specifically, the four positions are the following first to fourth positions. The first position is a position where the side wall 281a of the holding part 25C and the outer surface 246a of the accommodating part 24C are on the same side of the housing 20C, as shown in FIG. In the first position, the device connection section 22 and the second opening 281e are on the same side of the housing 20C. In this case, exposure of the connection line 90 connecting the device connection section 22 and the device 50 can be reduced. Furthermore, as shown in FIG. 15, the device connection section 22 and the second opening 281e are offset in the direction in which the mounting surface 245 of the housing section 24C and the mounting plate 280 of the holding section 25C face each other. In other words, the device connection portion 22 and the second opening 281e are not lined up in the direction in which the mounting surface 245 of the housing portion 24C and the mounting plate 280 of the holding portion 25C face each other. Therefore, compared to the case where the device connecting portion 22 and the second opening 281e are lined up in the direction in which the mounting surface 245 of the accommodating portion 24C and the mounting plate 280 of the holding portion 25C face each other, the device connecting portion 22 and the device 50 are The amount of bending of the connecting wire 90 to be connected can be reduced. Note that it is sufficient that the device connecting portion 22 and the second opening 281e have at least their center positions shifted in the direction in which the mounting surface 245 of the accommodating portion 24C and the mounting plate 280 of the holding portion 25C face each other. Preferably, the device connecting portion 22 and the second opening 281e do not overlap in the direction in which the mounting surface 245 of the accommodating portion 24C and the mounting plate 280 of the holding portion 25C face each other. Note that the second opening 281e may be made larger than the device connection portion 22 so that the position from which the connection wire 90 is pulled out can be selected to some extent. This also makes it possible to reduce the amount of bending of the connection wire 90 that connects the device connection section 22 and the device 50.

The second position is a position where the side wall 281a of the holding part 25C and the outer surface 246b of the accommodating part 24C are on the same side of the housing 20C, as shown in FIG. In other words, in the second position, the holding part 25C is moved from the first position around the rotation axis along the direction in which the mounting surface 245 of the accommodating part 24C and the mounting plate 280 of the holding part 25C face each other in plan view. This is the position rotated 90 degrees clockwise. The third position is a position where the side wall 281a of the holding part 25C and the outer surface 246c of the accommodating part 24C are on the same side of the housing 20C. That is, the third position is a position where the holding portion 25C is rotated 180 degrees clockwise in plan view around the above-mentioned rotation axis from the first position. The fourth position is a position where the side wall 281a of the holding part 25C and the outer surface 246d of the accommodating part 24C are on the same side of the housing 20C. That is, the fourth position is a position where the holding portion 25C is rotated 270 degrees clockwise in plan view from the first position around the above-mentioned rotation axis.

In this way, the holding part 25C can be attached to the accommodating part 24C at a plurality of positions. Therefore, the degree of freedom in attaching the device 50 is improved.

2.4 Fourth Modification The connection device of the fourth modification, as shown in FIGS. 17 to 19, has a holding portion 25D that is different from the holding portion 25C of the connection device 10C of the third modification. The connection device of the fourth modification can employ the accommodating portion 24C of the connection device 10C of the third modification.

The peripheral wall portion 280b surrounds the entire circumference of the opening 280a. Each hole 283b is provided for passing the shaft of a screw for attaching the device 50.
The eight holes 283b are located at two-fold rotationally symmetrical positions with respect to the center of the mounting plate 280. More specifically, four of the eight holes 283b are between the side wall 281a and the opening 280a, and the remaining four are between the side wall 281c and the opening 280a.

Main body 28D further includes a plurality of (four in this case) bosses 284 and protrusions 285.

The plurality of bosses 284 (four in this case) are used to attach the fixing plate 29D to the main body 28D with screws 501, as shown in FIG. Four bosses 284 are provided on the mounting plate 280. The four bosses 284 protrude from the mounting plate 280 toward the fixed plate 29D. Each boss 284 is cylindrical. Each boss 284 has a screw hole 284a corresponding to the screw 501 at the tip. The four bosses 284 are located at four-fold rotational symmetry with respect to the center of the mounting plate 280. More specifically, the four bosses 284 are located near the four corners of the mounting plate 280.

The protrusion 285 is used to position the fixing plate 29D with respect to the main body 28D. The protrusion 285 is provided on the mounting plate 280. The protrusion 285 is L-shaped in plan view. The protrusion 285 is located near one of the four bosses 284. Here, the protrusions 285 are arranged to correspond to the corners of the side walls 281c and 281d.

The fixed plate 29D is a metal plate. The fixing plate 29D has a rectangular shape (particularly a square shape) in plan view. The fixed plate 29D is smaller in size than the mounting plate 280.

Furthermore, the eight screw holes 290b are formed in the fixing plate 29D at positions facing the eight holes 283b of the main body 28D, respectively. The four holes 290c are used to fix the fixing plate 29D to the main body 28D. The four holes 290c are formed in the fixing plate 29D at positions facing the four bosses 284 of the main body 28D, respectively. Here, the four holes 290c are located near the four corners of the fixing plate 290.

To fix the fixing plate 29D to the mounting plate 280 (main body 28D), screws 501 can be fixed to the screw holes 284a of the four bosses 284 through the four holes 290c. At this time, the fixing plate 29D can be easily positioned on the main body 28D by placing any corner of the fixing plate 29D against the inner corner of the protrusion 285 of the main body 28D. Further, by fitting the peripheral wall portion 280b of the main body 28D into the opening 290a of the fixing plate 29D, the fixing plate 29D can be temporarily held on the main body 28D, making it easier to perform the joining operation using the screws 501.
