(Embodiment)
Hereinafter, a power supply device 1 according to an embodiment will be described using the drawings. However, the embodiment described below is only one of various embodiments of the present disclosure. The embodiments described below can be modified in various ways depending on the design, etc., as long as the objective of the present disclosure can be achieved. In addition, each figure described in the following embodiments is a schematic diagram, and the ratio of the size and thickness of each component in the figure does not necessarily reflect the actual size ratio. .

(overview)
As shown in FIG. 1, the power supply device 1 of this embodiment supplies power to a mobile device 9 (see FIG. 10). The mobile device 9 is movable along the rail 3. The power supply device 1 includes a trolley wire 2 and a connection member. The trolley wire 2 has an electric wire 20. The electric wire 20 is used as a power supply path to the mobile device 9 by being electrically connected to the mobile device 9 . The connecting member is a member for arranging the trolley wire 2 along the rail 3. Here, the description will focus on the second joint 7 (see FIGS. 6 and 15), which is an example of the connection member. The connecting member (second joint 7) includes a terminal portion 71 and a body 70. The terminal portion 71 is electrically connected to the electric wire 20. The body 70 holds the terminal portion 71. The terminal portion 71 includes a pair of

arms

711 and 712 and an opening/closing opening OP1 provided between the pair of

arms

711 and 712. The opening/closing opening OP1 changes the opening interval by an external force applied between the pair of

arms

711 and 712. The pair of

arms

711 and 712 sandwich the electric wire 20 inserted into the opening/closing opening OP1 from the front of the opening/closing opening OP1 while changing the opening interval of the opening/closing opening OP1 (Figs. 2, 6, 7, 13, 15) reference).

According to the above configuration, a worker or the like inserts the electric wire 20 of the trolley wire 2 into the opening/closing opening OP1 from the front, inserts the electric wire 20 between the pair of

arms

711 and 712 of the terminal part 71, and then inserts the electric wire 20 into the opening/closing opening OP1 from the front. 20 can be electrically connected to the terminal portion 71. In this way, the work of installing the trolley wire 2 can be simplified.

Moreover, the power supply device 1 of this embodiment can be assembled by the following construction method. The construction method of this embodiment is a construction method of the power supply device 1 that supplies power to the mobile device 9. The mobile device 9 is movable along the rail 3. The power supply device 1 includes a trolley wire 2 and a connection member. The trolley wire 2 has an electric wire 20. The electric wire 20 is used as a power supply path to the mobile device 9 by being electrically connected to the mobile device 9 . The connecting member is a member for arranging the trolley wire 2 along the rail 3. Here, the description will focus on the second joint 7 (see FIGS. 6 and 15), which is an example of the connection member. The connecting member (second joint 7) includes a terminal portion 71 and a body 70. The terminal portion 71 is electrically connected to the electric wire 20. The body 70 holds the terminal portion 71. The terminal portion 71 includes a pair of

arms

711 and 712 and an opening/closing opening OP1 provided between the pair of

arms

711 and 712. The construction method includes a first step and a second step. In the first step, the body 70 of the connecting member is attached to the rail 3. In the second step, after the first step, the electric wire 20 is inserted into the opening/closing opening OP1 from the front of the opening/closing opening OP1, and the electric wire 20 is sandwiched between the pair of

arms

711 and 712 while changing the opening interval of the opening/closing opening OP1.

Further, as shown in FIG. 1, the power supply device 1 of this embodiment supplies power to the mobile device 9. The mobile device 9 is movable along the rail 3. The power supply device 1 includes a trolley wire 2 and a plurality of supporters S1. As shown in FIG. 5, the trolley wire 2 includes an electric wire 20 and a covering member 21. The electric wire 20 is used as a power supply path to the mobile device 9 by being electrically connected to the mobile device 9 . The covering member 21 has electrical insulation properties. The covering member 21 covers a part of the electric wire 20. A plurality of supporters S1 are arranged along the rail 3 and support the trolley line 2. The covering member 21 covers at least the rear surface of the electric wire 20 and protrudes rearward from the rear surface of the electric wire 20. The distance I1 (thickness) in the front-rear direction from the rear surface of the electric wire 20 to the rear end of the covering member 21 is longer than the width (width W1 or W2) of the electric wire 20.

According to the above configuration, the interval I1 is longer than the width W1 or W2, that is, the trolley wire 2 is relatively long in the front-rear direction. Therefore, the possibility that the trolley wire 2 is bent is reduced.

For example, when attaching the trolley wire 2 to the supporter S1, force may be applied to the trolley wire 2 and the trolley wire 2 may be bent. Furthermore, when the mobile device 9 pushes the electric wire 20 via a current collector 90 (described later), the trolley wire 2 may be bent. Therefore, by making the trolley wire 2 relatively long in the front-rear direction as described above, it is possible to reduce the possibility that the trolley wire 2 will bend.

The terms "up and down," "front and back," and "left and right" as used in the present disclosure merely represent the relative positional relationship of the configuration of the power supply device 1, and are not intended to limit the direction in which the power supply device 1 is used. Therefore, for example, the power supply device 1 may be used in an orientation in which "front" in the present disclosure refers to top, bottom, rear, left, or right.

The arrows representing up and down, front and back, left and right in FIG.

(detail)
(1) Overall configuration The power supply device 1 supplies power to the mobile device 9 (see FIG. 10). The mobile device 9 is, for example, a self-propelled trolley or a hoist. The mobile device 9 receives power from an electric wire 20 installed on the rail 3 (see FIG. 3). The mobile device 9 moves along the rail 3 using the electric power obtained in this way as a power source.

The power supply device 1 and the mobile device 9 are used, for example, in a distribution warehouse or a factory. The mobile device 9 is used, for example, as a transport device for transporting articles.

As shown in FIG. 10, the mobile device 9 of this embodiment includes a current collector 90, and a plurality of current collectors 97 of the current collector 90 contact the electric wire 20. Further, the electric wire 20 is electrically connected to an external power source via a power line C1 (see FIG. 8). As a result, power is supplied from the external power source to the mobile device 9 via the electric wire 20 and the current collector 90.

FIG. 4 is an overall view of the power supply device 1. As shown in FIG. 4, the power supply device 1 is used together with a plurality of (two) rails 3. The power supply device 1 includes a plurality (eight) of trolley wires 2 and a plurality (nine) of supporters S1.

The nine supporters S1 include two first end members 4, three hangers 5, one first joint 6, one second joint 7, and two second end members 8. Note that when the two first end members 4 and the two second end members 8 are not distinguished, they are each referred to as "end member E1." That is, the first terminating member 4 and the second terminating member 8 are each an example of the terminating member E1. The termination member E1 supports the right end or left end of the electric wire 20. Furthermore, when the first joint 6 and the second joint 7 are not distinguished, they are each referred to as a "joint J1." That is, the first joint 6 and the second joint 7 are each an example of the joint J1. Joint J1 electrically connects two electric wires 20. The first end member 4 and the first and

second joints

6 and 7 are each an example of a connecting member. The connection member is a member that is responsible for at least one of relaying the electrical connection between the power line C1 and the electric wire 20, and relaying the electrical connection between the electric wires 20. The plurality of connection members are arranged in the left-right direction.

Furthermore, hereinafter, the eight trolley wires 2 may be distinguished and referred to as

trolley wires

2A, 2B, 2C, 2D, 2E, 2F, 2G, and 2H. Furthermore, below, the two rails 3 may be distinguished and referred to as

rails

3A and 3B.

(2) Trolley wire As shown in FIG. 8, the trolley wire 2 includes an electric wire 20 and a covering member 21. The electric wire 20 is made of a conductive material such as copper. The covering member 21 is made of electrically insulating synthetic resin or the like.

The longitudinal direction of the electric wire 20 is along the left-right direction. The covering member 21 covers a part of the electric wire 20. For example, when the trolley wire 2 is manufactured in a factory, the covering member 21 is provided from the left end to the right end of the electric wire 20. Then, a worker or the like uses a tool such as a cable cutter at the construction site of the power supply device 1 to peel off a portion of the covering member 21, for example, both end portions. Accordingly, in the power supply device 1 installed at the construction site, the covering member 21 is provided only in a part of the section between both ends of the electric wire 20 in the left-right direction (from the left end to the right end). In FIG. 8, a portion including the right end of the electric wire 20 is not provided with the covering member 21 and is exposed over the entire circumference. The exposed portion of the electric wire 20 is electrically connected to the terminal portion 41 of the connection member (for example, the first termination member 4 in FIG. 8).

As shown in FIG. 5, the trolley wire 2A and the trolley wire 2B are aligned in the vertical direction. Furthermore, the respective longitudinal directions of the trolley wire 2A and the trolley wire 2B are along the same direction (left-right direction). That is, the trolley wire 2A and the trolley wire 2B are arranged in parallel. The trolley wire 2A and the trolley wire 2B are connected to each other at the covering member 21. In other words, the covering member 21 of the trolley wire 2A is connected to the covering member 21 of the trolley wire 2B. In this embodiment, these two covering members 21 are connected via a connecting portion 22. The connecting portion 22 is configured integrally with the two covering members 21 described above. Thereby, the two covering members 21 are integrally formed.

Further, similar to the relationship between the trolley wire 2A and the trolley wire 2B, the trolley wire 2C (see FIG. 4) and the trolley wire 2D are vertically lined up and connected to each other at the covering member 21. Similarly, the trolley wire 2E and the trolley wire 2F are vertically lined up and connected to each other at the covering member 21. Similarly, the trolley wire 2G and the trolley wire 2H are vertically lined up and connected to each other at the covering member 21.

From left to right,

trolley wires

2A, 2C, 2E, and 2G are lined up in this order. From left to right,

trolley wires

2B, 2D, 2F, and 2H are lined up in this order.

The current collector 90 (see FIG. 10) includes four current collectors 97 (only two are shown in FIG. 10). Each current collector 97 is in contact with the electric wire 20 of one of the trolley wires 2 depending on the position of the current collector 90. Two of the four current collectors 97 are in contact with the electric wires 20 of one or two of the trolley wires 2 among the

trolley wires

2A, 2C, 2E, and 2G depending on the position of the current collector 90. There is. The remaining two current collectors 97 are in contact with the electric wires 20 of one or two of the trolley wires 2 among the

trolley wires

2B, 2D, 2F, and 2H depending on the position of the current collector 90. For example, when the current collector 90 moves to the right from a state in which the four current collectors 97 are in contact with the electric wires 20 of the

trolley wires

2A, 2B, the four current collectors 97 contact the electric wires 20 of the

trolley wires

2A, 2B, The state changes to a state in which it is in contact with the electric wires 20 of 2C and 2D. As the current collector 90 moves further to the right, the four current collectors 97 are brought into contact with the respective electric wires 20 of the

trolley wires

2C and 2D.

The shape of the electric wire 20 is the same among the plurality of trolley wires 2. As shown in FIG. 5, the electric wire 20 has a contact portion 201 and a protrusion 202.

The contact portion 201 is formed into a plate shape whose thickness direction is along the front-rear direction. The longitudinal direction of the contact portion 201 is along the left-right direction. Contact portion 201 has a front surface 2010. In a cross section perpendicular to the left-right direction, the center portion of the front surface 2010 is recessed toward the rear. Front surface 2010 is exposed to the outside. More specifically, the front surface 2010 is exposed without being covered by the covering member 21 in any section between both ends of the contact portion 201 in the left-right direction.

The vertical width W2 of the protruding portion 202 is smaller than the vertical width W1 of the contact portion 201. The vertical width W1 of the contact portion 201 is the maximum width of the electric wire 20 in the vertical direction.

The protruding part 202 protrudes from the rear surface of the contact part 201 and is formed along the longitudinal direction of the electric wire 20. More specifically, in a cross section perpendicular to the left-right direction, the protruding portion 202 protrudes from the center of the rear surface of the contact portion 201. The protruding portion 202 is a portion sandwiched between the pair of arms of the terminal portion along the longitudinal direction of the electric wire 20. Regarding the terminal portion 41 of the first termination member 4 (see FIG. 11), the protruding portion 202 is sandwiched between the pair of

arms

411 and 412 of the terminal portion 41. In other words, the pair of

arms

411, 412 sandwich the protrusion 202 inserted into the opening/closing opening OP1 between the pair of

arms

411, 412. According to this configuration, the width of the opening between the pair of

arms

411 and 412 can be made smaller compared to the case where the entire electric wire 20 is sandwiched between the pair of

arms

411 and 412. Therefore, it becomes easier for workers and the like to install the electric wires 20.

Below, first, the structure of the covering member 21 of the trolley wire 2A among the plurality of trolley wires 2 will be explained. The covering member 21 includes a covering main body 211, a plurality of (two in FIG. 5) rear ribs 212, and a plurality of (two in FIG. 5) front ribs 213.

The covering body 211 covers at least the rear surface of the electric wire 20. The covering body 211 is formed along the shape of the electric wire 20. More specifically, the covering body 211 is a portion of the covering member 21 where the thickness measured from the surface of the electric wire 20 is equal to or less than a threshold value. In the present embodiment, a portion of the covering member 21 whose thickness as measured from the surface of the electric wire 20 exceeds the threshold corresponds to the rear rib 212 or the front rib 213.

The covering main body 211 of this embodiment includes a front side part 2111 and a rear side part 2112. The front side portion 2111 covers an area of the contact portion 201 excluding a part of the front surface 2010. In a cross section perpendicular to the left-right direction, the front side portion 2111 has a C-shape with an open front. The rear side portion 2112 covers the entire protrusion 202 . In a cross section perpendicular to the left-right direction, the shape of the rear side portion 2112 is a U-shape with an open front.

The covering member 21 has a window 2011 that exposes the front surface of the electric wire 20, more specifically, the front surface 2010 of the contact portion 201. Window 2011 is an opening. The window 2011 is provided in the covering body 211 of the covering member 21.

The two rear ribs 212 protrude rearward from the covering body 211. More specifically, the two rear ribs 212 protrude from the rear side 2112 of the covering body 211. The rear rib 212 extends in the longitudinal direction (left-right direction) of the electric wire 20.

One of the two rear ribs 212 protrudes from the upper end of the rear side portion 2112. The other of the two rear ribs 212 protrudes from the lower end of the rear side portion 2112. The protrusion amounts of the two rear ribs 212 are equal to each other. "Equal" as used in the present disclosure is not limited to completely equal states, but also includes different states within a range that poses no practical problem.

The two front ribs 213 protrude forward from the covering body 211. More specifically, the two front ribs 213 protrude from the front side 2111 of the covering body 211.

The two front ribs 213 protrude forward from the edge of the covering body 211 forming the window 2011 and extend in the longitudinal direction (horizontal direction) of the electric wire 20. The two front ribs 213 are opposed to each other. More specifically, one front rib 213T (first front rib) of the two front ribs 213 projects forward from above the window 2011. The other front rib 213U (second front rib) of the two front ribs 213 projects forward from below the window 2011. In this way, since the front ribs 213 are provided on the upper and lower sides of the window 2011, these two front ribs 213 prevent the operator's fingers and the like from moving closer to the electric wire 20. Therefore, the possibility that the operator's fingers or the like will come into contact with the electric wire 20 can be reduced. Furthermore, the insulation distance between the two electric wires 20 is extended compared to the case where there is no front rib 213U.

Further, the amount of protrusion of the front rib 213U is larger than the amount of protrusion of the front rib 213T. In this way, since the amount of protrusion of the front rib 213U is relatively large, the insulation distance between the two electric wires 20 is relatively long.

The shapes of the

trolley wires

2C, 2E, and 2G are the same as the trolley wire 2A. On the other hand, the shapes of the

trolley wires

2B, 2D, 2F, and 2H are different from the shape of the trolley wire 2A with respect to the shapes of the two front ribs 213. More specifically, the trolley wire 2B is vertically symmetrical with respect to the trolley wire 2A. The shapes of the

trolley wires

2B, 2D, 2F, and 2H are the same.

One front rib 213V of the two front ribs 213 of the trolley wire 2B projects forward from above the window 2011. The other front rib 213W of the two front ribs 213 projects forward from below the window 2011. The amount of protrusion of the front rib 213V is larger than the amount of protrusion of the front rib 213W.

Here, the covering member 21 of the trolley wire 2A is referred to as a first covering member. The covering member 21 of the trolley wire 2B is called a second covering member. The first covering member is arranged above the second covering member. The first covering member and the second covering member each have two front ribs 213 facing each other. The two front ribs 213 protrude forward from the edge of the covering member 21 that forms the window 2011 and extend in the length direction (horizontal direction) of the electric wire 20. Of the two

front ribs

213T and 213U of the first covering member, the front rib 213U located on the inside protrudes more than the front rib 213T located on the outside of the first covering member and the second covering member. Of the two

front ribs

213V and 213W of the second covering member, the front rib 213V located on the inner side of the first covering member and the second covering member has a larger protrusion amount than the front rib 213W located on the outer side of the first covering member and the second covering member.

As described above, the thickness from the rear surface of the electric wire 20 to the rear end of the covering member 21 is longer than the width of the electric wire 20. Here, the thickness from the rear surface of the electric wire 20 to the rear end of the covering member 21 is, more specifically, the distance I1 from the rear surface of the electric wire 20 to the rear end of the covering member 21 in the front-back direction. Here, the width of the electric wire 20 that is compared with the interval I1 is the width of a predetermined portion of the electric wire 20 in the vertical direction.

The width of the electric wire 20 to be compared with the interval I1 may be the largest width W1 among the widths of each region of the electric wire 20. More specifically, the width of the electric wire 20 compared with the interval I1 may be the maximum width W1 of the electric wire 20 in the vertical direction.

Alternatively, the width of the electric wire 20 that is compared with the interval I1 may be the width W2 of the protrusion 202. More specifically, the width of the electric wire 20 that is compared with the interval I1 may be the width W2 of the protrusion 202 in the vertical direction.

In this embodiment, the interval I1 is longer than either of the widths W1 and W2. Further, the amount P1 of the rear rib 212 protruding from the covering body 211 in the front-rear direction is longer than either of the widths W1 and W2.

(3) Rail As shown in FIGS. 3 and 4, the rail 3A is arranged to the left of the rail 3B. The longitudinal direction of each rail 3 is along the left-right direction.

Although the

rails

3A and 3B have different lengths in the left-right direction, they have the same configuration in other respects. The configuration of the rail 3A will be described below with reference to FIG. 2.

The rail 3 is installed on the travel route of the mobile device 9 (see FIG. 10). The rail 3 is fixed to the frame of a building that constitutes a distribution warehouse or a factory, for example. The rail 3 is made of aluminum, for example.

Viewed from the left and right direction, the rail 3 has a C-shape with an open front. The rail 3 has a bottom wall 31, a first side wall 32, and a second side wall 33.

The thickness direction of the bottom wall 31 is along the front-rear direction. A plurality of supporters S1 are fixed to the bottom wall 31. More specifically, a plurality of supporters S1 are fixed to the bottom wall 31 by, for example, screws.

The first side wall 32 projects forward from the upper end of the bottom wall 31. The front end of the first side wall 32 is bent downward.

The second side wall 33 projects forward from the lower end of the bottom wall 31. The front end of the second side wall 33 is bent upward.

(4) Supporters As shown in FIGS. 3 and 4, a plurality of (seven in FIG. 3) supporters S1 are fixed to the rail 3A in a row in the left-right direction. More specifically, the seven supporters S1 fixed to the rail 3A are, in order from the left, the second end member 8, the hanger 5, the second joint 7, the hanger 5, the first joint 6, the hanger 5, and the first end.

arms

411 and 412 on the front surface of the terminal portion 41. The opening/closing opening OP1 can be opened/closed in the vertical direction. That is, in the terminal portion 41, the distance between the pair of

arms

411 and 412 can change. A connecting portion 413 is located behind the opening/closing opening OP1.

The terminal portion 41 has spring properties. More specifically, the configuration consisting of the pair of

arms

411, 412 and the connecting portion 413 has spring properties. When no external force is applied to the pair of

arms

411, 412, the opening/closing opening OP1 is closed due to the spring properties of the terminal portion 41. In the present disclosure, "the opening/closing port OP1 is closed" refers to a state in which the opening interval of the opening/closing port OP1 is relatively small. In the present disclosure, "the opening/closing port OP1 is open" refers to a state where the opening interval of the opening/closing port OP1 is relatively large. When the opening/closing port OP1 is closed, the tips of the pair of

arms

411 and 412 do not need to be in contact with each other. That is, when the opening/closing port OP1 is closed, the tips of the pair of

arms

411 and 412 may be opposed to each other with a gap between them.

In the process of inserting the protruding portion 202 of the electric wire 20 into the opening/closing opening OP1, the pair of

arms

411 and 412 are elastically deformed in the direction of opening the opening/closing opening OP1. The protruding portion 202 is sandwiched between the pair of

arms

411 and 412 due to the force of the pair of

arms

411 and 412 attempting to elastically return. At this time, the contact portion 201 of the electric wire 20 is located in front of the pair of

arms

411, 412 without being sandwiched between them. The terminal portion 41 of the first termination member 4 contacts (is sandwiched between) the right end portion or the left end portion of the electric wire 20 .

Please refer to FIG. 7 for the manner in which the terminal portion 41 sandwiches the protrusion portion 202 between the pair of

arms

411 and 412. Although FIG. 7 shows a state in which the terminal portion 71 of the second joint 7 sandwiches the protruding portion 202 between the pair of

arms

711 and 712, the terminal portion 41 also sandwiches the protruding portion 202 in the same manner. Further, FIG. 20A shows the opening interval WO1 when the opening/closing opening OP1 between the pair of

arms

411 and 412 of the terminal portion 41 is closed. FIG. 20B illustrates the opening interval WO2 when the opening/closing opening OP1 between the pair of

arms

411 and 412 of the terminal portion 41 is open. The opening interval WO2 is larger than the opening interval WO1. The protrusion 202 is inserted into the opening/closing opening OP1 with the opening/closing opening OP1 open, and then the opening/closing opening OP1 is closed, so that the protruding part 202 is sandwiched between the pair of

arms

411 and 412.

(10) Installation method Next, an example of a procedure for installing the power supply device 1 in a facility such as a distribution warehouse or a factory will be described. Note that the order of the following steps may be changed as appropriate. Further, steps may be added or omitted as appropriate.

The worker first fixes the plurality of supporters S1 to each of the plurality of rails 3. That is, as shown in FIG. 1, the worker fixes the plurality of supporters S1 to the front surface of the bottom wall 31 of the rail 3 so that the plurality of supporters S1 are lined up in the left-right direction. The worker attaches the supporter S1 to the rail 3 by, for example, passing a bolt through a penetration part provided in the supporter S1 and a hole provided in the bottom wall 31, and then passing the bolt through a nut on the rear surface of the rail 3. Fixed to.

Next, the worker fixes the rail 3 to, for example, the building frame. A worker fixes the rail 3 to the frame using, for example, bolts and nuts.

Next, the operator connects the two power lines C1 to the two power terminals 414 (see FIG. 11) of the first termination member 4 among the plurality of supporters S1. Further, the operator covers the two power lines C1 with the insulating cover 42 and attaches the insulating cover 42 to the body 40 using the fastening member 43. The operator also connects the two power lines C1 to the two power terminals 714 (see FIG. 15) of the second joint 7. Further, the operator covers the two power lines C1 with the insulating cover 72 and attaches the insulating cover 72 to the body 70 using the fastening member 73.

Next, the operator processes the covering member 21 of each of the plurality of trolley wires 2 as necessary. More specifically, the operator uses a tool to peel off a portion of the covering member 21.

For example, as shown in FIG. 8, the operator strips off the covering member 21 at the tip portion (first section) of the trolley wire 2 to completely expose the electric wire 20. The first section is a section including a portion of the trolley wire 2 that is sandwiched between the terminal portions 41.

Further, the operator cuts the plurality of rear ribs 212 of the covering member 21 in the second section adjacent to the first section of the electric wire 20, for example, as shown in FIG. The second section is a section including a portion of the electric wire 20 that is inserted into the body 40. Further, the second section is a section including a portion of the electric wire 20 that faces the insulating cover 42. In the second section, since the electric wire 20 is covered with the covering member 21, the electricity between the electric wire 20, the fastening member 43, and the power line C1 is lower than when the electric wire 20 in the second section is completely exposed. Higher insulation.

After peeling off a portion of the covering member 21 as necessary, the operator moves the plurality of trolley wires 2 from the front of the plurality of supports S1 so as to press them against the plurality of supports S1. Thereby, as shown in FIG. 2, the plurality of trolley wires 2 are inserted into each of the plurality of supporters S1. Note that the two vertically connected trolley wires 2 (for example,

trolley wires

2A and 2B) are inserted into each of the plurality of supporters S1 at once.

Furthermore, when the trolley wire 2 is inserted into the second joint 7, the protruding portion 202 of the electric wire 20 is sandwiched between the terminal portions 71, as shown in FIG. Further, when the trolley wire 2 is inserted into the first terminal member 4, the protruding portion 202 of the electric wire 20 is sandwiched between the terminal portions 41, as shown in FIG. Further, when the trolley wire 2 is inserted into the first joint 6, the protruding portion 202 of the electric wire 20 is sandwiched between the terminal portions 61. That is, the pair of arms 411, 412 (or 611, 612, or 711, 712) sandwich the electric wire 20 inserted into the opening/closing opening OP1 from the front of the opening/closing opening OP1 along the longitudinal direction of the electric wire 20. More specifically, the pair of arms 411, 412 (or 611, 612, or 711, 712) connect the electric wire 20 inserted into the opening/closing opening OP1 from the front of the opening/closing opening OP1 with the longitudinal direction of the electric wire 20 oriented in the left-right direction. sandwich.

The construction is completed when the worker inserts the corresponding trolley wires 2 into all the supporters S1. FIG. 4 shows the power supply device 1 in a state where construction has been completed.

As described above, among the plurality of supporters S1, the first terminating member 4 is a connecting member having a terminal portion 41 electrically connected to the electric wire 20, and the terminal portion 41 of the first terminating member 4 is a connecting member having a terminal portion 41 that is electrically connected to the electric wire 20. A pair of

arms

Similarly, among the plurality of supporters S1, the first joint 6 is a connecting member having a terminal portion 61 that is electrically connected to the electric wire 20, and the terminal portion 61 of the first joint 6 is a protruding portion of the electric wire 20. It includes a pair of

arms

611 and 612 that sandwich 202 between them. Similarly, among the plurality of supporters S1, the second joint 7 is a connecting member having a terminal portion 71 that is electrically connected to the electric wire 20, and the terminal portion 71 of the second joint 7 is a protruding portion of the electric wire 20. It includes a pair of

arms

711 and 712 that sandwich 202 between them.

In addition, the covering member 21 exposes the electric wire 20 in a part (first section) extending from the end (left end or right end) of the electric wire 20, and the pair of

arms

411, 412 of the terminal part 41, The electric wire 20 in the above-mentioned part of the section is sandwiched. Similarly, the pair of

arms

711 and 712 of the terminal portion 71 sandwich the electric wire 20 in the above-mentioned part of the section. Similarly, the pair of

arms

611 and 612 of the terminal portion 61 sandwich the electric wire 20 in the above-mentioned partial section.

Moreover, the first terminal member 4 among the plurality of connecting members includes an electrically insulating insulating cover 42 disposed between the power line C1 and the electric wire 20, a fastening member 43 that fastens the insulating cover 42 to the body 40, has. The above-mentioned partial section (first section) in which the electric wire 20 is exposed is a section different from the section (second section) in which the fastening member 43 is provided. Thereby, electrical insulation between the fastening member 43 and the electric wire 20 can be ensured.

Similarly, the second joint 7 among the plurality of connecting members includes an electrically insulating cover 72 arranged between the power line C1 and the electric wire 20, a fastening member 73 that fastens the insulating cover 72 to the body 70, has. The above-mentioned partial section (first section) in which the electric wire 20 is exposed is a section different from the section (second section) in which the fastening member 73 is provided.

(11) Advantages As mentioned above, the operator can simply move the trolley wire 2 from the front to the rear and insert it into the terminal section 41 (or 61 or 71), and the electric wire 20 and terminal section 41 (or 61 or 71) ) connection is completed. There is no need to use any tools in this process, and the operation of the trolley wire 2 can be as simple as moving the trolley wire 2 backward. In other words, the attachment of the trolley wire 2 is completed with one touch. Therefore, even if the power supply device 1 is installed in a narrow place, construction is easy.

Furthermore, in the power supply device 1 of this embodiment, even if the trolley wire 2 is made of a member that is difficult to bend, it is unlikely to cause problems during construction. Therefore, the trolley wire 2 can be manufactured from a material that is difficult to bend. Moreover, the trolley wire 2 can be formed into a shape that is difficult to bend.

The covering member 21 of the trolley wire 2 has a plurality of rear ribs 212. Further, the covering member 21 has a plurality of front ribs 213. Thereby, the trolley wire 2 is formed into a relatively long shape in the front-rear direction. Therefore, the possibility that the trolley wire 2 is bent about the axis along the vertical direction is reduced.

Further, the electric wire 20 of the trolley wire 2 has a contact portion 201 having a length in the vertical direction, and a protrusion portion 202 that protrudes rearward from the contact portion 201. Thereby, the cross-sectional shape of the electric wire 20 is Y-shaped. Due to this shape of the electric wire 20 and the fact that the covering member 21 has the rear rib 212 and the front rib 213, the section modulus of the trolley wire 2 becomes relatively large, so that the trolley wire 2 is difficult to bend.

Furthermore, since the trolley wire 2 is difficult to bend, the installation interval of the supporters S1 can be made relatively long. That is, the number of supporters S1 included in the power supply device 1 can be reduced.

Further, if the trolley wire 2 is easily bent, the trolley wire 2 may be bent as the moving device 9 moves while pushing the electric wire 20 backward by the current collector 97. Then, the electric wire 20 may separate from the current collector 97, and the electrical connection between the current collector 97 and the electric wire 20 may be broken. On the other hand, since the trolley wire 2 is formed to be difficult to bend as described above, the electrical connection between the current collector 97 and the electric wire 20 is difficult to be broken.
