(Embodiment 1)

(1) Overview

The power supply system 10 which concerns on this embodiment is equipped with the power supply path 1, the terminal device 2, and the fastening device 3, as shown to FIG. 1 and FIG. In addition, in the example of FIG. 1 and FIG. 2, the power supply system 10 is further equipped with the duct rail 4 as an installation object. However, the power supply system 10 may not include the installation object (duct rail 4) as a component. In addition, the power supply system 10 should just contain the power supply path 1 and the terminal device 2 in a component at least, and does not need to include the fastening device 3 as a component. In other words, the power supply system 10 may be composed of the power supply path 1 and the terminal device 2.

The power supply system 10 is a so-called insulated trolley which is used, for example, for feeding power to a mobile device moving in a facility in a facility such as an automated warehouse or a factory. As an example of a mobile device, there are an electric cart etc. which convey an article in a facility, and withdraw an article to a shelf or the like. The mobile device operates by receiving electric power from the power supply system 10. Specifically, the power feed passage 1 includes at least one core wire 11a, 11b electrically connected to an external power source. The mobile device is equipped with the electrical power collector 5 (refer FIG. 1) which has an electrical power collector. The current collector 5 moves in the extending direction of the core wires 11a and 11b in a state in which the current collectors are brought into contact with the core wires 11a and 11b. As a result, the mobile device can move (run) along the extension directions of the core wires 11a and 11b while receiving power from the power feeding path 1 to the current collector 5. In FIG. 1, the schematic shape of the electrical power collector 5 is shown by imaginary line (two dashed-dotted line).

In the present embodiment, a power supply system 10 for direct current, which feeds power to a mobile device that operates by receiving a supply of DC power with a DC motor, will be described as an example. In order to supply DC power to the current collector 5, this power supply system 10 employs a pair (two) of core wires 11a and 11b as a core wire of the power feeding path 1. have. In this case, it is assumed that the mobile device is a so-called light load device having a relatively low power consumption, and that the allowable current of the power feeding path 1 is relatively small. When the pair of core wires 11a and 11b are not particularly distinguished, each of the core wires 11a and 11b is also referred to simply as the "core wire 11".

The feed path 1 is installed in an installation object (here, the duct rail 4). In this embodiment, as an example, it is assumed that power is supplied to a mobile device moving in the horizontal direction, and the power supply path 1 is provided in the duct rail 4 provided along the horizontal direction. Hereinafter, the direction perpendicular to the horizontal plane (orthogonal) with respect to the horizontal plane in the state where the feed passage 1 is provided on the duct rail 4 will be described as "up and down direction", and the lower (vertical direction) will be described as "downward". . In addition, as the direction orthogonal to the up-down direction, the direction in which the power feeding path 1 and the current collector 5 face each other is "front and rear direction", and the current collector 5 is "front" when viewed from the power feeding path 1. It demonstrates as follows. In addition, the longitudinal direction of the duct rail 4, ie, the moving direction of the mobile device, will be described as "left and right direction", and the right side will be described as "right" and the left side as "left" from the front view of the feed passage 1 from the front. . Arrows indicating "up and down direction", "front and rear direction", and "left and right direction" in the drawings are merely shown for explanation and do not involve an entity. However, this direction is not intended to limit the use direction (installation direction) of the feed path 1. For example, "front" as defined here may be downward (vertical direction) in the installation state of the actual feeder 1.

By the way, there are two types of feed paths 1, a tension type and a connection type (non-tension type). The tension type feeding path 1 is used in the state in which the tension | pulling acted with respect to the core wire 11 from the both sides of the core wire 11 in the extending direction (left-right direction). Specifically, in the tension type feeder 1, both ends of the core wire 11 in the extending direction (left and right directions) are, for example, the duct rail 4 through the terminal device 2 and the tightening device 3. It is installed in). In this case, one end (first end 111) of the core wire 11 is provided on the duct rail 4 via the tightening device 3, and the other end (second end 112) of the core wire 11. Is installed in the duct rail 4 via the terminal device 2. The tension with respect to the core wire 11 is generated by the fastening device 3. However, the tightening device 3 is not an essential configuration as a configuration in which tension is applied to the core wire 11. For example, when the feeding path 1 is relatively short (for example, about several tens of centimeters), a pair of terminal devices 2 are provided on both sides in the extending direction of the feeding path 1, and power feeding in a state where tension is applied. It is also possible to construct the furnace 1 between a pair of terminal apparatuses 2.

In the tension type feeder 1, the feeder 1 is cut from the sufficiently long feeder 1 by the length required by the contractor. Therefore, in the tension type feeder 1, the feeder 1 of sufficient length (for example, 50m) is wound in the annular shape of the several tens of cm radius (henceforth an "overlapping state"). It is brought to the construction site (facilities) in). On the other hand, the connection type feed path 1 does not act on tension with respect to the core wire 11, and is used in the state which connected the some feed path 1 to the extension direction of the core wire 11, and is used. In the case of the connected feeder 1, when the feeder 1 is installed in the facility, the feeder 1 of a predetermined length (for example, 3 m) is connected and used as necessary. Therefore, in the connection type feeder 1, the some feeder 1 is carried in to the construction site (facilities) in the state which overlapped (henceforth "laminated state"). In addition, in any of the feed paths 1 of the tension type and the connection type, the feed path 1 is held by the holding member fixed to the duct rail 4 at appropriate intervals in the extending direction (left and right directions). Thereby, even when the electric power feeding path 1 is pushed back by the electrical power collector 5, the curvature of the electric power feeding path 1 is suppressed.

Comparing the tension type and the connection type, the tension type feeding path 1 can realize a relatively long feeding path seamlessly, and it is not necessary to connect a plurality of feeding paths 1 at the time of construction. There is an advantage that it can be omitted. Moreover, also about the installation space | interval of the holding member which hold | maintains the feeding path 1, the tension type feeding path 1 can be made wider than the connection type feeding path 1. In other words, since the tension-type feed path 1 is provided in a state where the warpage of the feed path 1 is suppressed by the tension, the feeder 1 of the tension type is the same as the connection type feeder 1 even if the holding member is wide. Difficulty in bending can be realized. For example, when the installation interval of the holding member in the connection type is 50 cm, the installation interval of the holding member in the tension type can be widened to about 2 m. Therefore, the tension type feeder 1 can reduce the labor of the installation for providing a holding member. On the other hand, if it is the connection type feeder 1, it is not necessary to apply tension with respect to the core wire 11, and the fastening apparatus 3 becomes unnecessary.

In this embodiment, as shown in FIG. 1 and FIG. 2, the case where the power feeding path 1 is a tension type is demonstrated as an example. In the present embodiment, the current collector 5 may be changed from the tension feeder 1 to the feeder of another facility such as a traverser or a turntable, which may be a tensioner or a connection. Assume the case. The "traverser" as used herein is, for example, a facility for moving the mobile device in the vertical direction or in the front-rear direction in parallel. In addition, the "change" here means, for example, when the mobile device operating in the facility X moves to the facility Y adjacent to the facility X, the electrical power collector 5 of the mobile device leaves the feeding path of the facility X, and installs the facility Y. It means to change to the feeder. Generally, a pair of feed paths which can be changed are provided side by side on the same straight line with an interval of about 1 mm to several cm.

In this case, as for the tension type feeder 1, the one end part (1st end part 111) of the extension direction in the core wire 11 is hold | maintained by the fastening apparatus 3, and the other end part (2nd end part) is carried out. The end 112 is maintained as the terminal unit 20 of the terminal device 2. The terminal unit 20 has a holding function for holding the power feeding passage 1 in a state where tension is applied from the tightening device 3, and a current collecting device between the power feeding passage 1 and the power feeding passage of another facility ( It has a guide function that enables changing of 5). As a result, in the power supply path 1, the power supply paths of other equipment adjacent to each other at the second end 112, which is an end portion of the terminal unit 20 side, of both ends in the extension direction in the core wire 11. It is possible to change the current collector 5 in between. On the other hand, in the 1st edge part 111 which is an edge part of the fastening device 3 side among the both ends of the extension direction in the core wire 11, the current collector 5 is not changed.

In the power supply system 10 according to the present embodiment, the terminal unit 20 further has a connection function for electrically connecting the power supply path 1 to an external circuit (here, an external power supply). Therefore, in the power supply system 10 which concerns on this embodiment, the power supply path 1 is electrically connectable with an external power supply to the terminal device 2 containing the terminal unit 20, and is connected from an external power supply. The power feeding to the power feeding path 1 is enabled by the terminal device 2. Thus, for example, even when the fastening device 3 is disposed at a position relatively far from the power distribution board, the power supply path 1 can be connected to the power distribution board by the terminal device 2, so that the external power supply (distribution board) and the power supply path 1 are provided. The length of the wire for electrically connecting the wire can be shortened. The holding function, the guide function, and the connection function of the terminal unit 20 will be described in detail in the section "(2.4) terminal device".

(2) Details

Hereinafter, the detail of each part of the power supply system 10 which concerns on this embodiment is demonstrated.

(2.1) Installation object

In this embodiment, the installation object consists of an elongate duct rail 4 extended in the left-right direction, as shown to FIG. 1 and FIG. The duct rail 4 is made of metal, for example. The duct rail 4 is, for example, installed between a pair of struts provided at regular intervals in the horizontal direction.

The duct rail 4 has a rear wall 41 disposed along a plane orthogonal to the front-rear direction, an upper wall 42 protruding forward from the upper edge of the rear wall 41, and a front of the lower edge of the rear wall 41. It has lower wall 43 which protruded by the front wall, and the front wall 44 which protruded downward from the front-end edge of the upper wall 42. As shown in FIG. Here, the rear wall 41, the upper wall 42, the lower wall 43, and the front wall 44 are integrally formed. In other words, the rear wall 41, the upper wall 42, the lower wall 43, and the front wall 44 are made of one metal plate. Moreover, the duct rail 4 has the opening part 45 between the lower edge of the front wall 44 and the front edge of the lower wall 43. The opening part 45 is formed over the full length of the duct rail 4 in a left-right direction. The rear wall 41 of the duct rail 4 is provided with a hole for fixing the terminal device 2 and the fastening device 3.

With respect to such a duct rail 4, the power feeding path 1 is provided on the front surface of the rear wall 41 at least by the terminal device 2 and the fastening device 3. In the state where the feed path 1 is provided in the duct rail 4, as shown in FIG. 1, a feed path (in the space surrounded by the rear wall 41, the upper wall 42, the lower wall 43, and the front wall 44) ( 1) is accommodated and the feed path 1 is exposed to the front through the opening part 45. The rear wall 41 of the duct rail 4 holds the feed path 1 at a suitable interval in the extension direction (left and right directions) between the terminal device 2 and the tightening device 3. The holding member may be fixed. By using the duct rail 4, even if there is no structure such as a wall or a ceiling, the holding member can be provided at a desired interval, and the feed path 1 can be provided. In addition, the duct rail 4 also has a function of protecting the power feeding passage 1 by surrounding the feeding passage 1.

(2.2) feeder

As shown in FIGS. 1-3, the power feeding path 1 is equipped with the at least 1 core wire 11a, 11b and the coating member 12. As shown in FIG.

In this embodiment, since the power supply path 1 supplies DC power as mentioned above, the power supply path 1 is equipped with the pair of core wires 11a and 11b of a positive electrode and a negative electrode. .

The core wire 11 is an elongate member that has conductivity and extends in the extension direction. In this embodiment, "extension direction" of the core wire 11 is set to "left-right direction". Here, as an example, the core wire 11 is made of metal such as copper or a copper alloy, and is a flat wire in which the cross-sectional shape orthogonal to the extension direction becomes a rectangular shape. In this embodiment, among the directions orthogonal to the extension direction, the short direction of the cross section of the core wire 11 is "front-back direction", and the long direction of the cross section of the core wire 11 is "up-down direction". In other words, the front-rear direction is the thickness direction of the core wire 11, and the up-down direction is the width direction of the core wire 11.

The covering member 12 has an electrical insulation and is an elongate member which covers the core wire 11. In other words, the covering member 12 is an elongated member extending in the extending direction (left and right directions) similarly to the core wire 11. In this embodiment, as an example, the coating member 12 is made of synthetic resin such as hard vinyl chloride. In the front surface of the covering member 12, the groove | channel opened forward is formed along the left-right direction, and the core wire 11 is accommodated in the groove | channel. Here, the groove is formed over the entire length of the covering member 12 in the left-right direction. As a result, the core wire 11 is exposed forward through the opening of the groove. In other words, the covering member 12 covers the core wire 11 so that the core wire 11 is exposed through the opening of the groove.

In the present embodiment, since the feed path 1 includes a pair of core wires 11a and 11b, a pair of grooves are also provided in the covering member 12 so as to correspond to the pair of core wires 11a and 11b. Formed. The pair of grooves are formed side by side with a predetermined interval in the vertical direction. That is, the pair of core wires 11a and 11b accommodated in the pair of grooves are arranged side by side in the vertical direction. In this way, the current collector 5 of the current collector 5 can be brought into contact with the core wire 11 in the groove by abutting the current collector 5 from the front with respect to the power feed passage 1. Power supply from the core wire 11 to the current collector 5 becomes possible.

The core wire 11 has the 1st end part 111 (refer FIG. 2) and the 2nd end part 112 (refer FIG. 2) in the both ends of an extending direction. The first end 111 protrudes from the covering member 12 to one side (here, left) in the extending direction, and the second end 112 protrudes from the covering member 12 to the other side (here, right) in the extending direction. . That is, one end part which protruded to the left side from the covering member 12 becomes the 1st end 111 among the both ends of the pair of core wires 11a and 11b in the extending direction, respectively, and it goes to the right side from the covering member 12 The other end that protrudes becomes the second end 112.

(2.3) Fastening device

The tightening apparatus 3 is equipped with the main body 31 and the tension generation part 32, as shown to FIG. 1 and FIG. The tightening device 3 is a device that exerts a tension in the extension direction with respect to the core 11 of the feed path 1. In other words, the tightening device 3 exerts a force (tension) on the core wire 11 in the direction to be pulled from both sides in the extension direction (left and right directions) of the core wire 11.

The housing constituting the outline of the main body 31 is made of synthetic resin, for example, and has electrical insulation properties. The main body 31 is accommodated in the duct rail 4 in a state in which the rear surface of the main body 31 is in contact with the front surface of the rear wall 41 of the duct rail 4. The housing of the main body 31 functions as an insulator for securing electrical insulation between the core wire 11 of the feed path 1 and the duct rail 4 and the tension generator 32.

The main body 31 has a holding function for holding the power feeding passage 1 similarly to the terminal unit 20 of the terminal device 2 described later. In the present embodiment, the main body 31 further has a connection function for electrically connecting the power supply path 1 to an external circuit (here, an external power source) similarly to the terminal unit 20. Specifically, the main body 31 houses the holding terminal portion (corresponding to the first terminal portion 21) and the electric wire terminal portion (corresponding to the second terminal portion 22) in the housing. The holding terminal portion mechanically holds the first end 111, which is one end in the extending direction of the core wire 11, and is electrically connected to the core wire 11. The electric wire terminal portion is a terminal for connecting the electric wire 7 (see FIG. 4) and is electrically connected to the holding terminal portion. As a result, the core wire 11 of the power feeding passage 1 can be electrically connected to an external circuit through the electric wire 7 in the main body 31. However, in this embodiment, the case where the electrical connection of the core wire 11 and an external circuit is performed by the terminal unit 20 of the terminal device 2 instead of the main body 31 of the fastening device 3 is demonstrated. do. Therefore, the electric wire 7 for electrically connecting the core wire 11 with an external circuit is not connected to the main body 31 of the fastening apparatus 3, but is connected to the terminal unit 20. FIG.

The tension generating unit 32 has a main shaft 321 made of a headless screw (stud bolt), a nut 322, and a compression coil spring 323.

One end (right end) in the longitudinal direction (left and right directions) of the main shaft 321 is fixed to the main body 31. The main shaft 321 is supported by the supporting jig 6 (refer FIG. 1 and FIG. 2) which consists of general-purpose jigs, such as L angle. The supporting jig 6 is fixed to the rear wall 41 of the duct rail 4, and the main shaft 321 is supported by the supporting jig 6 in a state where the supporting jig 6 penetrates in the left-right direction.

The nut 322 is attached to the end part (left end part) on the opposite side to the main body 31 in the longitudinal direction of the main shaft 321. The compression coil spring 323 is combined with the main shaft 321 so that the main shaft 321 may penetrate the inside of the compression coil spring 323. The compression coil spring 323 is arrange | positioned between the support jig 6 and the nut 322 in the left-right direction.

According to this structure, the magnitude | size of the tension acting on the core wire 11 through the main body 31 from the tension generation part 32 by moving the nut 322 in the left-right direction by operating the nut 322 I can regulate it. That is, for example, when the nut 322 moves in the direction closer to the supporting jig 6, the compression coil spring 323 is compressed between the nut 322 and the supporting jig 6, and the compression coil spring 323 By the elastic force of), the nut 322 receives a force in a direction away from the supporting jig 6. At this time, the nut 322 receives a force in the left direction from the compression coil spring 323, and the main shaft 321 is pulled in the left direction together with the nut 322. Therefore, the tension (the force which pulls the core wire 11 to the left direction) which acts on the core wire 11 of the feed path 1 from the tension generation part 32 becomes large. On the contrary, when the nut 322 moves away from the supporting jig 6, the elastic force of the compression coil spring 323 decreases, and the force in the left direction acting on the nut 322 from the compression coil spring 323 is reduced. Becomes smaller. Therefore, the tension (force that pulls the core wire 11 to the left) acting on the core wire 11 of the feed path 1 from the tension generating portion 32 becomes small.

In other words, the terminal device 2, together with the tightening device 3, exerts a force (tension) on the core wire 11 in a direction in which the core wire 11 is pulled from both sides in an extension direction (left and right directions) of the core wire 11. .

The terminal unit 20 holds the power feeding path 1. The feed path 1 is a tension type feed path in which tension along the extension direction acts on the core wire 11 from the first end 111 (see FIG. 2) as described above. The terminal unit 20 holds the 2nd end part 112 (refer FIG. 2) on the opposite side to the 1st end part 111 which the tightening apparatus 3 hold | maintains in the both ends of the extension line of the core wire 11. .

It has a pair of 2nd terminal part 22a, 22b. When the pair of first terminal portions 21a and 21b are not particularly distinguished, each of the first terminal portions 21a and 21b is also referred to simply as the "first terminal portion 21". When the pair of second terminal portions 22a and 22b are not particularly distinguished, each of the second terminal portions 22a and 22b is also referred to simply as the "second terminal portion 22".

The first terminal portion 21 mechanically holds the second end 112 of the core wire 11 and is electrically connected to the core wire 11. In the present embodiment, the first terminal portion 21 is a screw terminal, and the tightening screw 211 is tightened in a state in which the second end 112 of the core wire 11 is inserted into a metal plate formed in a prismatic shape. This is connected to the core wire 11. Here, two fastening screws 211 are used with respect to one 1st terminal part 21, and the pair of 1st terminal parts 21a and 21b hold a pair of core wires 11a and 11b, respectively. Keep it. Therefore, the holding | maintenance function which hold | maintains the feeding path 1 of the state in which the tension acted from the tightening apparatus 3 is implement | achieved. Moreover, each fastening screw 211 is a screw which has an overload protection function (torque limiter), and is comprised so that a head part may be folded when it is tightened by the torque more than specified torque.

The second terminal portion 22 is a terminal for connecting the electric wire 7 and is electrically connected to the first terminal portion 21. The electric wire 7 here is a 2-wire type (two core type) electric wire corresponding to a pair of 2nd terminal part 22a, 22b. In this embodiment, the 2nd terminal part 22 is a screw type terminal, and the terminal screw 221 is tightened, and is connected mechanically and electrically with the electric wire 7. The electric wire 7 connected to the pair of second terminal portions 22 is connected to an external circuit (here, an external power supply). As a result, the pair of core wires 11a and 11b in the feed path 1 includes a pair of first terminal portions 21a and 21b, a pair of second terminal portions 22a and 22b, and an electric wire ( It is electrically connected to an external circuit (external power supply) via 7). Therefore, the connection function for electrically connecting the power supply path 1 to an external circuit (external power supply) is implemented.

The second terminal portion 22 is held by the unit body 23 in the direction in which the electric wire 7 connected to the second terminal portion 22 is drawn out toward the first end 111 side (left side) in the extending direction. . That is, as shown in FIG. 6, the electric wire 7 connected to the 2nd terminal part 22 is pulled out from the unit main body 23 to the same side (left side) as the power feeding path 1. Here, one 1st terminal part 21a and one 2nd terminal part 22a are integrally formed with one metal plate. Similarly, the other 1st terminal part 21b and the other 2nd terminal part 22b are integrally formed with the metal plate of 1 sheet.

The unit main body 23 and the cover 24 both have electrical insulation properties. Here, the unit main body 23 and the cover 24 are all made of synthetic resin. The cover 24 is provided on the rear (rear) side of the unit main body 23. The unit main body 23 holds the 1st terminal part 21 and the 2nd terminal part 22. As shown in FIG. The terminal unit 20 is accommodated in the duct rail 4 in a state in which the rear surface of the unit main body 23 is in contact with the front surface of the rear wall 41 of the duct rail 4. The unit main body 23 functions as an insulator for ensuring electrical insulation between the core wire 11 and the electric wire 7, and the duct rail 4 and the fixing member 8.

On the back surface of the unit main body 23, a storage recess 237 (see Fig. 5) for accommodating the first terminal portion 21 and the second terminal portion 22 is formed. The cover 24 is provided with respect to the unit main body 23 so as to cover the storage recess 237. That is, in the back side (rear) of the unit main body 23 in the front-back direction, between the unit main body 23 and the cover 24, the 1st terminal part 21 by the storage recessed part 237. And a space for accommodating the second terminal portion 22.

Moreover, as shown in FIG. 6, the unit main body 23 further has the partition wall 238 which divides the internal space of the accommodating recess 237 in the up-down direction. The first terminal part 21a and the second terminal part 22a are accommodated in the space above the partition wall 238 among the internal spaces of the storage recessed part 237. The 1st terminal part 21b and the 2nd terminal part 22b are accommodated in the space below the partition wall 238 among the internal space of the storage recessed part 237.

Moreover, the line passing hole 239 for passing the electric wire 7 connected to the 2nd terminal part 22 is formed in the left surface of the accommodating recessed part 237 in the unit main body 23. As shown in FIG. The line passing hole 239 is connected to the storage recess 237 and extends to the left side from the storage recess 237. Thereby, the electric wire 7 connected to the 2nd terminal part 22 is pulled out from the unit main body 23 to the same side (left side) as the power feeding path 1 through the wire passage hole 239.

As shown in FIG.4 and FIG.5, the cover 24 is screwed with respect to the unit main body 23 using a pair of assembly screw 251 and a pair of assembly nut 252. As shown in FIG. The pair of assembling nuts 252 are insert nuts and are embedded in a pair of assembling holes 253 formed in the rear surface of the unit main body 23. At the left end of the cover 24, a pair of transmission holes 241 for passing the pair of assembling screws 251 is formed. In other words, the pair of assembling screws 251 pass through the cover 24 and are fastened to the pair of assembling nuts 252 embedded in the unit main body 23. As a result, the cover 24 is provided with respect to the unit main body 23.

In addition, a pair of protruding walls 242 (see FIG. 4) and ribs 243 (see FIG. 4), which face each other in the up-down direction, are provided on the opposing surface (front surface) of the cover 24 with the unit body 23. Formed. The pair of protruding walls 242 are disposed at positions where the cover 24 interferes with the head of the fastening screw 211 in a state where the cover 24 is provided in the unit main body 23. As a result, in the state where the head of the tightening screw 211 having the overload protection function (torque limiter) is not folded, that is, the tightening screw 211 is not tightened with a torque higher than the specified torque, the cover 24 To the unit main body 23 is regulated. That is, if the head part of the fastening screw 211 remains, the right end part of the cover 24 will be in the state which floated from the back surface of the unit main body 23, and will block the restricting part 235 mentioned later, and to the fixing member 8 Installation of the terminal unit 20 is prohibited.

The rib 243 is located between the pair of transmission holes 241. In the state where the cover 24 is provided in the unit main body 23, the rib 243 functions as suppressing the tension of the electric wire 7 connected to the 2nd terminal part 22. In other words, the rib 243 is inserted between the second terminal portion 22 and the line passing hole 239 by the electric wire 7 between the rear surface of the unit body 23 to extend the direction ( The movement of the wire 7 in the right and left directions is regulated. The cover 24 is screwed to the unit main body 23 with a pair of assembling screws 251 through a pair of transmission holes 241 located on both sides of the rib 243 in the vertical direction. Therefore, by tightening the assembling screw 251, the rib 243 can be penetrated into the electric wire 7, and the tension of the electric wire 7 can be suppressed more firmly.

By the way, in the terminal unit 20 which concerns on this embodiment, the unit main body 23 has at least 1 guide groove 231a, 231b and the tension receiving part 232, as shown in FIG. .

The guide grooves 231a and 231b are grooves for accommodating the core wire 11 of the power feeding path 1 and are formed between the both ends in the extension direction on the front surface 233 of the unit main body 23. In other words, the guide grooves 231a and 231b are formed between both ends of the front surface 233 of the unit main body 23 in the direction along the extension direction of the core wire 11. That is, the guide grooves 231a and 231b are opened to the front, and are formed in the form which penetrates the unit main body 23 over the full length of an extension direction. In the present embodiment, since the feed path 1 includes a pair of core wires 11a and 11b, the pair of guide grooves also correspond to the pair of core wires 11a and 11b in the unit main body 23 as well. (231a, 231b).

The pair of guide grooves 231a and 231b are formed side by side at a predetermined interval in the vertical direction. In addition, an opening 230 for arranging the pair of first terminal portions 21a and 21b accommodated in the storage recess 237 is provided in a part of the bottom and the inner surface of the pair of guide grooves 231a and 231b. Formed. In other words, the space in the storage recess 237 continues to the space in the guide groove 231 through the opening 230. The 1st terminal part 21 accommodated in the storage recessed part 237 is exposed through the opening 230 from a part of the bottom face and the inner side face of the guide groove 231.

The core wire 11a is introduced into the guide groove 231a from the left side of the unit main body 23 and is connected to the first terminal portion 21a in the guide groove 231a. The core wire 11b is introduce | transduced into the guide groove 231b from the left side of the unit main body 23, and is connected to the 1st terminal part 21b in the guide groove 231b. That is, the pair of core wires 11a and 11b accommodated in the pair of guide grooves 231a and 231b are arranged side by side in the vertical direction. When the pair of guide grooves 231a and 231b are not particularly distinguished, each of the guide grooves 231a and 231b is also referred to simply as a "guide groove 231".

Thereby, the current collector 5 of the current collector 5 is guided by abutting the current collector 5 from the front with respect to the unit main body 23 in the state of holding the second end 112 of the core wire 11. The core wires 11 in the grooves 231 can be brought into contact with each other, whereby the electric power feeding from the power feeding path 1 to the current collector 5 becomes possible. In addition, since the guide groove 231 is formed between both ends of the unit main body 23 in the extending direction, the current collector of the current collector 5 moves the unit main body 23 through the guide groove 231. Can pass in the extension direction. That is, in the state of continuing to feed power from the power feeding path 1 to the current collector 5, the current collector 5 can move so as to pass through the terminal unit 20 along the extension direction. And when passing through the terminal unit 20, the electrical power collector 5 is guided so that it may move to an extension direction by restrict | limiting the movement to an up-down direction by the guide groove 231. As shown in FIG. Therefore, the guide function which enables the change of the electrical power collector 5 between the power feeding path 1 and the power feeding path of other facilities is implement | achieved.

Here, the width dimension (the dimension in the vertical direction) of the guide groove 231 is set smaller than the dimension in the vertical direction of the first terminal portion 21 except for the portion where the opening 230 is formed in the guide groove 231. have. Therefore, the 1st terminal part 21 arrange | positioned in the opening 230 cannot move in the guide groove 231 along an extension direction. Thus, the first terminal portion 21 is held in the unit main body 23 in a state arranged in the opening 230, and even if a force in the left direction with respect to the first terminal portion 21 acts from the core wire 11, the first terminal portion 21 is maintained. The terminal portion 21 is stopped in the opening 230.

In addition, the guide groove 231 has the width expansion part 236 at the edge part (right end part) on the opposite side (right side) to the 1st end part 111 in an extension direction, as shown to FIG. 7 (a). Have The width expansion part 236 makes the width dimension (dimension of the up-down direction) of the guide groove 231 wider than the outer side (right side) of the unit main body 23. As shown in FIG. As a result, at the time of changing the current collector 5, the width-expansion portion 236 is guided and shifted even if there is a positional shift in the vertical direction between the feed path before the change and the feed path after the change. Riding is possible.

The tension receiving portion 232 regulates the movement of the unit main body 23 in the direction approaching the first end 111, and thus, the unit main body () from the feed passage 1 via the first terminal portion 21. 23) It is the part that receives the tension acting on it. In the present embodiment, the tension receiving portion 232 is a vertical plane that faces the first end 111 side (left side) in the extension direction and is perpendicular to the extension direction. In other words, the left side of the unit main body 23 constitutes the tension receiving portion 232. The term "orthogonal" as used herein is not limited to the state of being strictly crossed at 90 degrees, but includes a state that is orthogonal to approximately 90 degrees. The tension receiving portion 232 is in contact with the contact surface 81 of the fixing member 8, which will be described later, so as to restrict the movement of the unit main body 23 in the direction closer to the first end 111 (left direction). Consists of. That is, the unit main body 23 makes the power feeding path 1 by making the left side surface of the unit main body 23 used as the tension receiving part 232 contact a part of the fixing member 8 (contact surface 81). ) Is subjected to the tension in the left direction acting on the unit main body 23 via the first terminal portion 21.

Moreover, the unit main body 23 is the 1st end part 111 from the vertical surface (left side surface of the unit main body 23) which is the tension receiving part 232, as shown to FIG.7 (a) and FIG.7 (b). It further has a pair of positioning protrusion 234 which protrudes to () side (left side). The pair of positioning projections 234 are provided at both ends in the vertical direction at the rear end of the left surface of the unit main body 23. The unit main body 23 places the positioning projection 234 on the positioning recess 832 of the fixing member 8 described later, thereby positioning the front and rear directions with respect to the fixing member 8. However, the positioning projection 234 is not limited to one pair but may be provided only one.

Moreover, the unit main body 23 further has the control part 235 which regulates the movement to the front of the unit main body 23, as shown in FIG. The restricting part 235 is a through hole formed in the right side surface of the storage recessed part 237 in the unit main body 23 in this embodiment. In the restricting portion 235, the restricting piece 84 of the fixing member 8 described later is inserted from the storage recess 237 side (left side). In other words, when the restricting piece 84 is caught by the restricting portion 235, the forward movement of the unit main body 23 is restricted, and the unit main body 23 from the rear wall 41 of the duct rail 4 is restricted. Injury is regulated.

The fixing member 8 is a member for fixing the unit main body 23 of the terminal unit 20 to the duct rail 4 (installation object). In this embodiment, the fixing member 8 is a fixing tool (fixing jig) made of metal, such as iron, for example.

As shown in FIG. 8, the fixing member 8 has the contact surface 81 which contact | connects the tension receiving part 232 from the 1st end part 111 side (left side) in an extension direction. The tension receiving portion 232 is configured to restrict the movement of the unit main body 23 in the direction closer to the first end 111 by being in contact with the contact surface 81. Specifically, as shown in FIG. 4 and FIG. 5, the fixing member 8 includes a contact surface 81, a fixing piece 82, a pair of side wall portions 83, and a restricting piece 84. Have The fixed piece 82, the pair of side wall portions 83, and the restricting piece 84 are integrally formed of one metal plate.

The fixing piece 82 is a strip | belt-shaped board long in an extending direction (left-right direction). The fixing piece 82 is provided with a pair of mounting holes 821 arranged in the extending direction. The fixing piece 82 is attached to the rear wall 41 of the duct rail 4 by a pair of mounting bolts 91 passing through the pair of mounting holes 821. The mounting mechanism 92 is attached to the front end of the mounting bolt 91 that penetrates the rear wall 41. The installation mechanism 92 has an installation nut 92a, a spring washer 92b, and a flat washer 92c. Thereby, the fixing member 8 is provided in the duct rail 4 so that a part of the rear wall 41 of the duct rail 4 may be interposed between the installation mechanism 92, and the duct rail 4 Is fixed without rattling.

Here, in this embodiment, the mounting bolt 91 is a welding bolt and is integrated with the fixed piece 82 by welding. Therefore, compared with general bolts, such as a hexagonal bolt, the height (protrusion amount from the front surface of the fixing piece 82) of the head part of the mounting bolt 91 can be suppressed low. This avoids the interference between the mounting bolt 91 and the electric wire 7 connected to the second terminal portion 22.

The pair of side wall portions 83 protrude forward from both ends in the vertical direction of the fixing piece 82. Here, a pair of side wall part 83 is provided only in the 1st edge part 111 side (left side) rather than the center of the longitudinal direction (extension direction) of the fixing piece 82. As shown in FIG. Here, the contact surface 81 is a cross section (right side) of the opposite side (right side) to the 1st end part 111 of the extension direction in the pair of side wall part 83. As shown in FIG. The contact surface 81 is in contact with the tension receiving portion 232 of the terminal unit 20 from the first end 111 side (left side) in the extension direction. Thereby, as shown in FIG. 8, even if tension X1 of the left direction acts on the unit main body 23 from the feed route 1 via the 1st terminal part 21, it moves to the left side of the unit main body 23. As shown in FIG. It is regulated by this fixing member 8, and the tension receiving part 232 can receive the tension X1.

Moreover, the positioning recessed part 832 is formed in the rear end part of the contact surface 81 in the pair of side wall part 83. As shown in FIG. The positioning protrusion 234 of the unit main body 23 is caught by this positioning recessed part 832, and positioning of the front-back direction of the terminal unit 20 with respect to the fixing member 8 is performed.

Here, the tension receiving part 232 is provided in the range which becomes rearward from the front-end edge of the core wire 11 in the front-back direction. Specifically, as shown in FIG. 8, the front surface of the pair of side wall portions 83 is positioned on the fixing member 8 such that the front surface of the pair of side wall portions 83 is located at a distance rearward from the front edge of the core wire 11 by a distance D1. The height (protrusion amount from the front surface of the fixing piece 82) of the pair of side wall portions 83 is set. That is, the whole left side (vertical surface) of the unit main body 23 does not comprise the tension receiving part 232, but the part which contacts the contact surface 81 among the left side (vertical surface) of the unit main body 23 is tensioned. The receiving part 232 is comprised. Therefore, the height of the pair of side wall portions 83 having the contact surface 81 is suppressed to be low, so that the range that functions as the tension receiving portion 232 among the left surfaces (vertical surfaces) of the unit body 23 is limited. I can narrow it down. Thereby, the tension receiving part 232 is provided in the range which becomes rearward from the front-end edge of the core wire 11 in the front-back direction.

In addition, the height (protrusion amount from the front surface of the fixing piece 82) of the pair of side wall portions 83 is lower toward the first end 111 side (left side) in the extension direction. Therefore, the front end surface of a pair of side wall part 83 comprises the inclined surface 831 inclined toward the left side. Thus, in this embodiment, the dimension of the front-back direction of a pair of side wall part 83 becomes small, so that it moves away from the contact surface 81 (right side surface of a pair of side wall part 83) in an extension direction.

The restricting piece 84 protrudes from an end (right end) on the opposite side (right side) to the first end 111 in the extending direction of the fixing piece 82. The restricting piece 84 protrudes toward the opposite side (right side) from the first end 111. As shown in FIG. 8, the restricting piece 84 restricts movement to the front of the unit main body 23 by being inserted into the restricting portion 235 of the unit main body 23. In other words, when the restricting piece 84 is caught by the restricting portion 235, the injury of the unit main body 23 from the fixing piece 82 is restricted.

Here, the tension receiving portion 232 and the restricting portion 235 are arranged so that the tension receiving portion 232 is the first end 111 side (left side) in the extending direction. In other words, the restricting portion 235 is located on the opposite side (right side) from the first end 111 with respect to the tension receiving portion 232 in the extending direction. With such a positional relationship, as shown in FIG. 8, when the tension X1 of the left direction acts on the unit main body 23 from the feed route 1 via the 1st terminal part 21, the unit main body 23 is carried out. In response to the moment X2 acting on, the rotation of the unit main body 23 is efficiently regulated by the restricting portion 235.

(3) Modification

The power supply system 10 which concerns on Embodiment 1 is only one of the various embodiment of this invention. As for the power supply system 10 which concerns on Embodiment 1, if the objective of this invention can be achieved, various changes can be made according to a design. Hereinafter, the modified example of Embodiment 1 is listed. Modifications described below can be applied in appropriate combinations.

The mobile device which operates by receiving electric power supply from the power supply system 10 is not limited to an electric trolley | bogie, For example, a crane and the vehicle for carrying a person may be sufficient. The facility to which the power supply system is applied is not limited to an automatic warehouse or a factory, but may be, for example, a amusement facility or a store. In addition, the power supply system 10 is not limited to indoors and may be for outdoor use used outside of a building.

The power supply system 10 is not limited to the supply of DC power, but may be used to supply AC power such as, for example, single-phase two-wire or three-phase three-wire. In addition, the power supply system 10 may be used for the communication which transmits signals, such as a control signal, with a load (mobile device here, for example), for example. In other words, the power feeding path 1 is not limited to a two-wire system having a pair (two) of core wires 11, but may have one core wire or three or more core wires 11.

The fixing member 8 is not limited to metal, but may be made of synthetic resin, for example.

In addition, although Embodiment 1 demonstrated the case where the power feeding path 1 extended in linear form, the power feeding path 1 may extend along a curve. For example, when the moving path of the mobile device which receives electric power from the power supply system 10 is a curved path, the power feeding path 1 is curved along this moving path. Even in such a case, by subdividing the feeding path 1 in the extending direction of the feeding path 1, the extending direction of the feeding path 1 is defined as a linear extension direction. In other words, in the curved feeding path 1, the tangential direction in each part of the subdivided feeding path 1 becomes an extension direction.

In addition, the cross-sectional shape orthogonal to the extension direction of the core wire 11 is not limited to a rectangular shape, For example, the groove | channel of cross-sectional V shape or cross-sectional U shape may be formed in the whole surface of the core wire 11, for example.

In addition, although the example in which the restricting piece 84 of the fixing member 8 is inserted into the restricting part 235 of the unit main body 23 was shown in Embodiment 1, the control part 235 and the restricting piece 84 are shown. The relationship between unevenness may be reversed. In other words, a recess may be formed in the restricting piece 84 of the fixing member 8, and a projection inserted into the recess may be formed in the restricting portion 235 of the unit body 23.

In addition, the unit main body 23 of the terminal unit 20 may be integrated with the fixing member 8. In this case, instead of the tension receiving part 232 having the same vertical surface as that of the first embodiment, the portion corresponding to the fixing piece 82 of the fixing member 8 is the unit main body 23 in the unit main body 23. It constitutes a tension receiving part that receives the tension acting on.

In addition, the fixing member 8 may be integrated with the duct rail 4 so that a part of the duct rail 4 functions as the fixing member 8. In this case, the terminal unit 20 is directly attached to the installation object (duct rail 4) without using the fixing member 8. In this case, the terminal device 2 is comprised only by the terminal unit 20, and does not contain the fixing member 8 in a component.

In addition, the second terminal portion 22 may be electrically connected to the first terminal portion 21. For example, the second terminal portion 22 and the first terminal portion 21 are formed of respective metal plates, and the braided wire ( It may be electrically connected with a braided wire or the like.

In addition, the tension receiving part 232 and the restricting part 235 may be arranged so that the tension receiving part 232 may be opposite to the first end 111 (right side) in the extending direction. In other words, the restricting portion 235 may be located on the first end 111 side (left side) with respect to the tension receiving portion 232 in the extending direction.

In addition, the cover 24 is not limited to the structure screwed with respect to the unit main body 23, For example, the cover 24 may be provided with the snap-fit structure with respect to the unit main body 23. As shown in FIG. .

In addition, also about the fastening apparatus 3, it is not limited to the structure demonstrated by Embodiment 1, It can change suitably. For example, the tension generator 32 is not limited to the structure in which tension is applied to the core wire 11 by the elastic force of the compression coil spring 323, and may be applied to the core wire 11 in another manner. For example, the tightening device 3 may have a plurality of tension generating portions 32.

In addition, the installation object is not limited to the duct rail 4, For example, it may be a structure, such as a wall or a ceiling. In other words, the feed path 1 may be directly installed in a structure such as a wall or a ceiling without passing through the duct rail 4.

(Embodiment 2)

As shown in FIG. 9, as for the terminal apparatus 2A which concerns on this embodiment, the structure of the contact surface 81A of the tension receiving part 232A of the terminal unit 20, and the fixing member 8A is embodiment. It differs from the terminal device 2 related to 1. Hereinafter, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and description is abbreviate | omitted suitably.

In the present embodiment, the tension receiving portion 232A is inclined to face toward the first end 111 side (left side) in the extending direction (left and right directions) and inclined forward with respect to a plane orthogonal to the extending direction. . That is, the inclined surface which is a part of the unit main body 23A and faces to the left front constitutes the tension receiving portion 232A.

According to this structure, the unit main body 23A is provided in the fixing member 8A in the form which the tension receiving part 232A enters behind the right end part of the side wall part 83 of the fixing member 8A. Therefore, the rise of the unit main body 23A from the fixing piece 82 becomes more difficult.

The configuration of Embodiment 2 can be applied in appropriate combination with the various configurations (including modifications) described in Embodiment 1.

(theorem)

As described above, the terminal units 20 and 20A according to the first aspect have at least one core wire 11 having both ends in the extending direction as the first end 111 and the second end 112. The feed path 1 is maintained. In the feed path 1, the tension along the extension direction acts on the core wire 11 from the first end 111 side. The terminal units 20 and 20A include a first terminal portion 21, a second terminal portion 22, and unit main bodies 23 and 23A. The first terminal portion 21 mechanically holds the second end portion 112 and is electrically connected to the core wire 11. The second terminal portion 22 is electrically connected to the first terminal portion 21 and is a terminal portion for connecting the electric wire 7. The unit main bodies 23 and 23A hold the 1st terminal part 21 and the 2nd terminal part 22. As shown in FIG. The unit main bodies 23 and 23A have guide grooves 231 and tension receiving portions 232 and 232A. The guide groove 231 is formed between the both ends of the extension direction in the front surface 233 of the unit main bodies 23 and 23A, and accommodates the core wire 11. The tension receiving portions 232 and 232A regulate the movement of the unit main bodies 23 and 23A in the direction closer to the first end 111, thereby opening the first terminal portion 21 from the feed path 1. The tension acting on the unit main bodies 23 and 23A is received.

According to this configuration, the power supply path 1 (core wire) is provided by abutting the current collector 5 from the front with respect to the unit main bodies 23 and 23A in a state where the second end 112 of the core 11 is held. Power supply to the current collector 5 from (11) becomes possible. Since the guide groove 231 is formed between both ends of the unit main body 23, 23A in the extension direction, it is a current collector (with the power supply from the power feeding path 1 to the current collector 5 being continued). 5) may pass through the terminal units 20 and 20A along the extending direction. In addition, since the terminal units 20 and 20A have a second terminal portion 22, a connection function for electrically connecting the feed path 1 to an external circuit is realized. Therefore, when the fastening device 3 is arrange | positioned in the position comparatively far from an external circuit, the feed path 1 can be electrically connected with the external circuit by the terminal units 20 and 20A. As a result, the length of the electric wire 7 for electrically connecting the external circuit and the power feeding path 1 can be shortened.

As for the terminal unit 20 which concerns on a 2nd aspect, in the 1st aspect, the tension receiving part 232 is a vertical surface which faces the 1st edge part 111 in an extension direction, and is orthogonal to an extension direction. It is preferable. According to this structure, the tension receiving part 232 can receive the tension which acts on the unit main body 23 from the feeding path 1 efficiently.

As for the terminal unit 20 which concerns on a 3rd aspect, in the 2nd aspect, the positioning body 234 which protrudes toward the 1st end part 111 from the vertical surface which is the tension receiving part 232 is a part. It is preferable to have more). According to this structure, positioning of the terminal unit 20 with respect to the fixing member 8 is attained.
