DETAILED DESCRIPTION

[0029] (Implementation Method)

[0030] Hereinafter, the collector device 1 of the embodiment will be described using the accompanying drawings. However, the embodiment described below is only one of the various embodiments disclosed herein. The embodiment described below can be modified in various ways according to the design, etc., as long as the purpose of the present disclosure can be achieved. In addition, the figures described in the following embodiments are schematic figures, and the size and thickness ratios of the components in the figures do not necessarily reflect the actual size ratios.

[0031] (summary)

[0032] Figure 1 The current collector 1 of this embodiment is shown. The current collector 1 is mounted on a mobile device 9 (see Figure 3 The mobile device 9 is a device that uses electric power to move. The mobile device 9 is, for example, a self-propelled trolley or a crane. The mobile device 9 is moved from a trolley wire T1 (see Fig.12 The mobile device 9 uses the power thus obtained as a power source to move along the track.

[0033] The current collector 1 of this embodiment transmits power from the trolley wire T1 to the mobile device 9. Figure 1 to Figure 4 As shown, the current collector 1 includes an arm 6 for supporting the current collector 2. The current collector 2 is in contact with the sliding wire T1. The arm 6 has a first surface 64a, a first rib 61, and a through hole 641. The first surface 64a is in contact with a cable 8 for electrically connecting the current collector 2 to the mobile device 9. The first rib 61 sandwiches the cable 8 between the first rib 61 and the first surface 64a and holds the cable 8. The through hole 641 allows the cable 8 to pass through.

[0034] According to the above configuration, the cable 8 is sandwiched between the first rib 61 and the first surface 64a and passed through the through hole 641, thereby suppressing positional deviation of the cable 8. Therefore, it is possible to suppress the cable 8 from becoming loose or being pulled.

[0035] In addition, the current collector 1 of this embodiment transmits power from the trolley wire T1 to the mobile device 9. Figure 1 to Figure 3 As shown, the current collector 1 includes a fixing portion F1 and an arm 6. The fixing portion F1 is mounted on a base 7, and the base 7 is fixed to a moving device 9. The arm 6 includes a first mounting portion 66 mounted on the fixing portion F1 and a second mounting portion 67, and the current collector 2 is mounted on the second mounting portion 67. The current collector 2 is in contact with the sliding wire T1. The fixing portion F1 includes a first hook portion 41 and a second hook portion 42 that can be hooked on corresponding portions of the base 7. By releasing the hooks of the first hook portion 41 and the second hook portion 42 from the base 7, the fixing portion F1 can be removed from the base 7.

[0036] According to the above structure, it is possible to perform work on the current collector 1 after removing the fixing portion F1 and the arm 6 from the base 7 and moving them. The work is, for example, replacement work of the components (collector 2, etc.) of the current collector 1. According to the above structure, it is possible to move the fixing portion F1 and the arm 6 to a place suitable for work, such as a wide place. Therefore, compared with the case where the work is performed while the fixing portion F1 and the arm 6 are kept attached to the base 7, it is easier to perform the work.

[0037] (Details)

[0038] (1) Overall structure

[0039] In the following figures, the X-axis direction is defined as the left-right direction, the Y-axis direction is defined as the front-back direction, and the Z-axis direction is defined as the up-down direction. Furthermore, the positive direction of the X-axis direction is defined as the left side, the positive direction of the Y-axis direction is defined as the front side, and the positive direction of the Z-axis direction is defined as the upper side. However, the above directions are examples and are not intended to limit the directions in which the current collector 1 is used. For example, the current collector 1 may be used in such a way that the positive direction of the Y-axis becomes the upper side. In addition, the arrows indicating the directions in the drawings are merely marked for the purpose of explanation and are not accompanied by entities.

[0040] like Figure 1 As shown, the current collector 1 includes two current collectors 2, two connector parts 3, two fixing parts F1, two compression springs S1, two arms 6, a base 7, and two cables 8. However, the base 7 and the two cables 8 may not be components of the current collector 1. The two fixing parts F1 each include a base 4 and a holder 5.

[0041] (2) Current collector

[0042] The structure of the two current collectors 2 is common. Here, the description will be made focusing on one current collector 2.

[0043] like Figure 4 As shown, the current collector 2 has a contact portion 21 , a cover 22 , a penetration portion 23 , and a shaft portion 24 .

[0044] The contact part 21 is a conductor. The contact part 21 is formed of, for example, a metal material. The contact part 21 is connected to the sliding wire T1 (see Fig.12 The length direction of the contact portion 21 is along the X-axis direction.

[0045] The cover 22 has electrical insulation properties. The cover 22 is formed of, for example, synthetic resin. The cover 22 covers a portion of the contact portion 21. One end (positive side of the Y axis) of the contact portion 21 is exposed to the outside of the cover 22.

[0046] The penetration portion 23 is formed of, for example, synthetic resin and includes a connecting portion 231 , a column portion 232 , and two protruding pieces 233 .

[0047] The connection portion 231 is connected to the cover 22. More specifically, the shaft portion 24 passes through through holes provided in the connection portion 231 and the cover 22, thereby connecting the connection portion 231 to the cover 22. The cover 22 can rotate together with the contact portion 21 around the connection portion (shaft portion 24) with the connection portion 231. The shaft portion 24 is, for example, a screw.

[0048] The column 232 is cylindrical in shape. The length direction of the column 232 is along the Y-axis direction. The column 232 protrudes from the connecting portion 231. The column 232 has a slit 2320 at the top end (negative side of the Y-axis) on the side opposite to the connecting portion 231. The slit 2320 is a recessed portion that is recessed from the top end of the column 232 toward the connecting portion 231 side.

[0049] The two protrusions 233 protrude from the top end of the column 232 on the side opposite to the connecting portion 231 in a direction intersecting the length direction of the column 232. The protrusion direction (left direction) of one of the two protrusions 233 is opposite to the protrusion direction (right direction) of the other protrusion 233. A slit 2320 is formed between the two protrusions 233.

[0050] (3) Connector

[0051] The two connector portions 3 (first connector portions) correspond one-to-one to the two current collectors 2. Each connector portion 3 is formed integrally with the cover 22 of the corresponding current collector 2.

[0052] The two connector parts 3 have a common structure. Here, the description will be made focusing on one connector part 3.

[0053] like Figure 4 As shown, the connector part 3 has an outer shell 31 and a terminal housed in the outer shell 31. The outer shell 31 has electrical insulation. The outer shell 31 is formed of, for example, a synthetic resin. The outer shell 31 protrudes from the cover 22 of the current collector 2. More specifically, the outer shell 31 protrudes from the cover 22 in the negative direction of the Y axis. The terminal is electrically connected to the contact portion 21 of the current collector 2.

[0054] The connector portion 3 is configured to be connectable to a cable 8 .

[0055] (4) Cables

[0056] The two cables 8 correspond to the two connector portions 3 in a one-to-one manner. Each cable 8 is connected to the corresponding connector portion 3 .

[0057] The two cables 8 have a common structure. Here, the description will be made focusing on one cable 8 .

[0058] like Figure 4 As shown, the cable 8 has a cable body 81 and a second connector part 82. The cable body 81 includes a linear conductor and an insulating coating 811 covering the conductor. The cable body 81 is flexible. The second connector part 82 is connected to one end of the cable body 81. The second connector part 82 is configured to be connectable to the connector part 3 (first connector part). In addition, the second connector part 82 is configured to be disconnected from the connector part 3. In more detail, the second connector part 82 and the connector part 3 are connected by pressing the second connector part 82 into the connector part 3. In addition, the connection between the second connector part 82 and the connector part 3 is disconnected by pulling the second connector part 82 out of the connector part 3.

[0059] (5) Arm

[0060] The two arms 6 correspond one-to-one to the two current collectors 2. To each arm 6, a corresponding current collector 2 is mounted.

[0061] In addition, the two arms 6 correspond to the two cables 8 in a one-to-one manner. Each arm 6 holds the corresponding cable 8 .

[0062] The structure of the two arms 6 is common. Here, the description will be made focusing on one arm 6.

[0063] like Figure 3 , Figure 4 As shown, the arm 6 includes a first rib 61 , two second ribs 62 , a third rib 63 , an arm body 64 , a wall portion 65 , a first mounting portion 66 , a second mounting portion 67 , a second guide portion 68 , and a second spring arrangement portion 69 .

[0064] The longitudinal direction of the arm body 64 is along the X-axis direction. The arm body 64 has a rectangular parallelepiped shape.

[0065] The arm body 64 has a first surface 64a and a second surface 64b. The first surface 64a is a surface (front surface) on the positive side of the Y axis. The first surface 64a is in contact with the sliding line T1 (see Fig.12 The second surface 64b is a surface (rear surface) on the opposite side to the first surface 64a. The second surface 64b is a surface facing the base 7.

[0066] The arm body 64 has a through hole 641 (first through hole) and a second through hole 642 .

[0067] The through hole 641 is provided on the first surface 64 a and penetrates the arm body 64 along the Y-axis direction.

[0068] The second through hole 642 is provided on the first surface 64a and penetrates the arm body 64 along the Y-axis direction (see Figure 7 ). The second through hole 642 is provided on the positive side of the X axis with respect to the through hole 641.

[0069] Furthermore, the arm body 64 has a third through hole 643. The third through hole 643 penetrates the arm body 64 in the Z-axis direction. The first mounting portion 66 passes through the third through hole 643.

[0070] The wall portion 65 protrudes from the first surface 64a along the normal direction of the first surface 64a. That is, the wall portion 65 protrudes from the first surface 64a along the positive direction of the Y axis. The wall portion 65 protrudes from the end on the positive side of the Z axis in the arm body 64. The thickness direction of the wall portion 65 is along the Z axis direction. The length direction of the wall portion 65 is along the X axis direction.

[0071] The first rib 61 protrudes from the wall portion 65. More specifically, the first rib 61 protrudes from the wall portion 65 in the negative direction of the Z axis. The first rib 61 is cylindrical in shape. The top end of the first rib 61 is rounded and formed in a dome shape.

[0072] The part 80d of the cable 8 (see Fig. 9 ) is sandwiched between the first surface 64a and the first rib 61. The cable 8 is arranged along the wall portion 65 (see Fig. 9 The longitudinal direction of the wall portion 65 is along the extending direction (X-axis direction) of the cable 8 between the first surface 64 a and the first rib 61 .

[0073] The two second ribs 62 protrude from the first surface 64a along the normal direction of the first surface 64a. That is, the second ribs 62 protrude from the first surface 64a along the positive direction of the Y axis. The second ribs 62 protrude from the end of the arm body 64 on the negative side of the Z axis. The second ribs 62 are plate-shaped. The thickness direction of the second ribs 62 is along the Z axis direction. The second ribs 62 are opposite to the wall portion 65.

[0074] The two second ribs 62 are arranged along the X-axis direction. Hereinafter, one of the two second ribs 62 is also referred to as the second rib 62a, and the other of the two second ribs 62 is also referred to as the second rib 62b. The second rib 62b is provided on the positive side of the X-axis relative to the second rib 62a. In the arm body 64, a third through hole 643 is provided on the negative side of the Y-axis relative to the second rib 62a. The third through hole 643 is provided on the negative side of the Y-axis relative to the first surface 64a. In addition, the third through hole 643 is provided between the first rib 61 and the through hole 641.

[0075] The first rib 61 is provided at a position visible through the gap between the two second ribs 62. Specifically, the first rib 61 is provided at a position visible through the gap between the two second ribs 62 when viewed from the negative side (lower side) of the Z axis.

[0076] like Figure 7 , Fig.12As shown, the distance L1 between the two second ribs 62 at the height position of the first rib 61 is longer than the shortest distance L2 between the wall portion 65 and the two second ribs 62. The distance L1 between the two second ribs 62 at the height position of the first rib 61 is the length of a line segment that overlaps the first rib 61 and connects the two second ribs 62 along the X-axis direction when viewed from the Z-axis direction.

[0077] like Figure 3 , Figure 4 As shown, the third rib 63 protrudes from the wall portion 65. More specifically, the third rib 63 protrudes from the wall portion 65 in the negative direction of the Z axis. The third rib 63 is in a plate shape. The thickness direction of the third rib 63 is along the Y axis direction. The third rib 63 faces the first surface 64a.

[0078] The third rib 63 is provided between the first rib 61 and the through hole 641. In addition, the third rib 63 is provided between the second rib 62a and the through hole 641.

[0079] The first mounting portion 66 is, for example, a screw. The first mounting portion 66 is mounted on the fixing portion F1. More specifically, the first mounting portion 66 passes through the third through hole 643 and the fourth through hole 521 of the fixing portion F1 (see Figure 4 ) The arm body 64 is rotatably mounted on the holder 5 of the fixing portion F1.

[0080] The second mounting portion 67 is provided at the end on the negative side of the X-axis in the arm body 64. The second mounting portion 67 is a portion where the current collector 2 is mounted. The second mounting portion 67 has a mounting hole 671. The current collector 2 is mounted on the second mounting portion 67 by inserting the through portion 23 of the current collector 2 into the mounting hole 671. The width of the through portion 23 is larger than the width of the mounting hole 671, but when the through portion 23 is clamped, the width of the through portion 23 becomes smaller than the width of the mounting hole 671. Thus, the through portion 23 can be inserted into the mounting hole 671.

[0081] In more detail, the width of the column portion 232 in the through portion 23 is smaller than the width of the mounting hole 671. The width of the top end portion of the through portion 23 provided with the two protrusions 233 is larger than the width of the mounting hole 671. By clamping the two protrusions 233 from both sides, the through portion 23 is elastically deformed so as to narrow the width of the slit 2320, and the width of the top end portion of the through portion 23 is reduced. By inserting the top end portion of the through portion 23 into the mounting hole 671 in this state, the current collector 2 is mounted on the second mounting portion 67.

[0082] The mounting hole 671 penetrates the second mounting portion 67 in the Y-axis direction. The tip of the through portion 23 is inserted from the opening on the positive side of the Y-axis in the mounting hole 671 and protrudes from the opening on the negative side of the Y-axis (see Figure 2). Then, the two protrusions 233 are elastically restored, so that the width of the top end of the through-portion 23 increases. Therefore, the two protrusions 233 function as anti-dropping parts that prevent the through-portion 23 from coming out of the mounting hole 671.

[0083] In addition, when the two protruding pieces 233 are clamped from both sides in a state where the through-portion 23 is inserted into the mounting hole 671, the through-portion 23 is elastically deformed so as to narrow the width of the slit 2320, thereby reducing the width of the top end of the through-portion 23. Furthermore, by moving the through-portion 23 (together with the current collector 2 as a whole) in the positive direction of the Y axis, the through-portion 23 can be pulled out from the mounting hole 671 and the current collector 2 can be removed from the arm 6. In this way, the current collector 2 can be moved in one direction and removed from the arm 6. Therefore, the current collector 2 can be easily replaced.

[0084] like Figure 3 , Fig.10 As shown in FIG. 1 , the second guide portion 68 protrudes from the arm body 64. More specifically, the second guide portion 68 protrudes from the second surface 64b of the arm body 64. The second guide portion 68 is provided on the positive side of the X axis with respect to the first mounting portion 66.

[0085] like Figure 3 As shown, the second spring arrangement portion 69 protrudes from the arm body 64. More specifically, the second spring arrangement portion 69 protrudes from the second surface 64b of the arm body 64. The second spring arrangement portion 69 is provided at a position closer to the negative side of the X axis than the first mounting portion 66.

[0086] The arm 6 is rotatable about the first mounting portion 66. The distance L3 between the first mounting portion 66 and the first rib 61 (see Figure 7 ) is greater than the distance L4 between the first mounting portion 66 and the second mounting portion 67 (see Figure 7 ) is short. Therefore, even if a force is applied to the arm body 64 during the operation of sandwiching the cable 8 between the first rib 61 and the first surface 64a, the displacement of the first rib 61 is relatively small. Therefore, the operation is easy.

[0087] (6) Fixed part

[0088] like Figure 1 As shown, the two fixing portions F1 correspond one-to-one to the two arms 6. The corresponding arm 6 is attached to each fixing portion F1.

[0089] Each fixing portion F1 includes a holder 5 and a base 4 , and the holder 5 is attached to the base 4 .

[0090] The two fixing portions F1 correspond to the two compression springs S1 in a one-to-one manner, and each fixing portion F1 holds the corresponding compression spring S1.

[0091] The two fixing portions F1 have a common structure. Here, the description will be made focusing on one fixing portion F1.

[0092] (6.1) Retaining parts

[0093] like Figure 3 , Figure 4 As shown, the holder 5 includes a support portion 51 , a coupling portion 52 , a first retaining portion 53 , a spring seat 54 , and a first spring placement portion 55 .

[0094] The support portion 51 is columnar in shape. The axial direction of the support portion 51 is along the Y-axis direction. The coupling portion 52 protrudes from the top end portion 511 in the positive direction of the Y-axis in the support portion 51. The coupling portion 52 is a portion where the arm 6 is mounted. The width of the coupling portion 52 in the Z-axis direction is smaller than the width of the support portion 51 in the Z-axis direction. The coupling portion 52 has a fourth through hole 521. The fourth through hole 521 penetrates the coupling portion 52 in the Z-axis direction. The support portion 51 has a recessed portion 512 on the surface on the negative side of the Y-axis.

[0095] The first mounting portion 66 is mounted on the holder 5. More specifically, the first mounting portion 66 passes through the third through hole 643 of the arm body 64 and the fourth through hole 521 of the holder 5. Thus, the first mounting portion 66 rotatably mounts the arm body 64 on the holder 5. In addition, the arm body 64 faces the top end portion 511 of the support portion 51. The arm 6 can rotate around the first mounting portion 66 until the arm body 64 contacts the top end portion 511.

[0096] The first retaining portion 53 protrudes from the side surface of the support portion 51. More specifically, the first retaining portion 53 protrudes from the support portion 51 in the positive direction of the X axis.

[0097] The spring seat 54 protrudes from the side surface of the support portion 51. More specifically, the first anti-detachment portion 53 protrudes from the support portion 51 in the negative direction of the X axis. The spring seat 54 has a recess 541 on the surface on the positive side of the Y axis. The compression spring S1 is inserted into the recess 541.

[0098] The first spring arrangement portion 55 protrudes from the spring seat 54 . More specifically, the first spring arrangement portion 55 protrudes from the bottom surface of the recessed portion 541 of the spring seat 54 .

[0099] More specifically, the compression spring S1 is a compression coil spring. Figure 3 As shown, the first end of the compression spring S1 is opposite to the spring seat 54 of the retainer 5. In addition, the first spring arrangement portion 55 is inserted into the first end of the compression spring S1. The second end of the compression spring S1 is opposite to the second surface 64b of the arm body 64. In addition, the second spring arrangement portion 69 is inserted into the second end of the compression spring S1. Thus, the compression spring S1 can be retained.

[0100] The compression spring S1 supports the arm 6. That is, the compression spring S1 applies a spring force in the positive direction of the Y axis to the arm body 64.

[0101] The compression spring S1 is sandwiched between the area between the first mounting portion 66 and the second mounting portion 67 in the second surface 64b (the area where the second spring arrangement portion 69 is provided) and the spring seat 54 of the holder 5 of the fixing portion F1. When the compression spring S1 pushes the arm body 64 in the positive direction of the Y axis, the arm 6 rotates around the first mounting portion 66 in such a manner that the second mounting portion 67 of the arm 6 moves in the positive direction of the Y axis. As a result, the collector 2 is subjected to a force in the positive direction of the Y axis, so that the collector 2 and the sliding wire T1 (see FIG. 1 ) can be secured. Fig.12 ) contact pressure.

[0102] (6.2) Base

[0103] like Figure 3 , Figure 5 , Figure 6 As shown, the base 4 includes a first hook portion 41 , a second hook portion 42 , a main body 43 , a stopper 44 , a cylindrical portion 45 , and a second anti-detachment portion 46 .

[0104] The body 43 includes a bottom portion 431 and a side portion 432 .

[0105] The bottom 431 is in a plate shape. The thickness direction of the bottom 431 is along the Y-axis direction. The bottom 431 has a first outer surface 431a. The normal line of the first outer surface 431a is along the negative direction of the Y-axis. The bottom 431 includes a recessed portion 431e formed on the first outer surface 431a.

[0106] The side portion 432 protrudes from the bottom portion 431. More specifically, the side portion 432 protrudes from the positive side of the X-axis in the bottom portion 431 toward the positive direction of the Y-axis. The side portion 432 has a first guide portion 47 at the top end in the positive direction of the Y-axis. The first guide portion 47 is a V-shaped groove. The side portion 432 includes a second outer surface 432b. The normal line of the second outer surface 432b is along the positive direction of the X-axis.

[0107] Thus, the main body 43 includes the first outer surface 431a and the second outer surface 432b having different normal directions. The first hook portion 41 protrudes from the first outer surface 431a, and the leaf spring-shaped second hook portion 42 protrudes from the second outer surface 432b.

[0108] The first hook portion 41 protrudes in the negative direction of the X axis from the top end on the negative side of the X axis in the bottom portion 431 including the first outer surface 431a. The first outer surface 431a has the above-mentioned recessed portion 431e at a position on the positive side of the X axis relative to the first hook portion 41.

[0109] The second hook portion 42 includes a leaf spring portion 421 and a claw portion 422. The leaf spring portion 421 includes a first portion 421c and a second portion 421d. The first portion 421c of the leaf spring portion 421 protrudes from the second outer surface 432b in the positive direction of the X axis, and the second portion 421d of the leaf spring portion 421 protrudes from the top of the first portion 421c in the positive direction of the Y axis. Thus, the second hook portion 42 is formed in the shape of the letter L. The boundary portion between the first portion 421c and the second portion 421d (the portion corresponding to the corner of the letter L) is rounded.

[0110] The second hook portion 42 has a leaf spring portion 421 and is easily elastically deformed. The elastic modulus of the second hook portion 42 is smaller than the elastic modulus of the first hook portion 41.

[0111] The claw portion 422 protrudes from the second portion 421d of the leaf spring portion 421. More specifically, the claw portion 422 protrudes in the positive direction of the X-axis.

[0112] The stopper 44 protrudes from the tip of the second portion 421d. More specifically, the stopper 44 protrudes in the positive direction of the X axis. The stopper 44 is provided on the positive side of the Y axis with respect to the claw 422. The stopper 44 is provided with a gap between it and the claw 422.

[0113] The cylindrical portion 45 protrudes from the bottom portion 431. More specifically, the cylindrical portion 45 protrudes in the positive direction of the Y axis. The cylindrical portion 45 is provided on the negative side of the X axis with respect to the side portion 432.

[0114] The second retaining portion 46 protrudes from the side portion 432. More specifically, the second retaining portion 46 protrudes in the negative direction of the X-axis.

[0115] like Figure 3 As shown in the figure, the holder 5 is mounted on the base 4. That is, the holder 5 is moved in the negative direction of the Y axis and the cylindrical portion 45 of the base 4 is inserted into the recess 512 of the holder 5, so that the holder 5 is mounted on the base 4. In addition, at this time, the first anti-detachment portion 53 of the holder 5 is arranged on the negative side of the Y axis relative to the second anti-detachment portion 46 of the base 4 and is opposite to the second anti-detachment portion 46, so that the holder 5 can be prevented from being separated from the base 4. More specifically, in a state where the cylindrical portion 45 of the base 4 is inserted into the recess 512 of the holder 5, the holder 5 is rotated around the cylindrical portion 45, whereby the first anti-detachment portion 53 is arranged on the negative side of the Y axis relative to the second anti-detachment portion 46.

[0116] (7) Base

[0117] The base 7 is formed of, for example, a metal material. More specifically, the base 7 is formed by, for example, punching and bending a metal plate.

[0118] like Figure 3 , Figure 5 As shown, the base 7 includes a bottom plate 71 and side plates 72 .

[0119] The bottom plate 71 includes a bottom plate body 710 , two third hook portions 711 , and two protrusions 712 .

[0120] The bottom plate body 710 is formed in a plate shape. The thickness direction of the bottom plate body 710 is along the Y-axis direction. The bottom plate body 710 includes two fifth through holes 7101 and two sixth through holes 7102 .

[0121] The two third hooks 711 correspond to the two fifth through holes 7101 in a one-to-one manner. Each third hook 711 is provided at a position covering a portion of the corresponding fifth through hole 7101. Each third hook 711 protrudes from the bottom plate body 710. More specifically, each third hook 711 protrudes in the positive direction of the Y axis.

[0122] The two third hooking parts 711 correspond to the two bases 4 one by one. The first hooking part 41 of the corresponding base 4 is hooked to each third hooking part 711. Figure 3 As shown, the first hook portion 41 passes through the fifth through hole 7101 and is arranged on the negative side of the Y axis relative to the third hook portion 711. In the Y axis direction, the first hook portion 41 and the third hook portion 711 are in contact with each other. Thus, the movement of the base 4 in the positive direction of the Y axis can be restricted. Furthermore, in the X axis direction, the base 4 and the third hook portion 711 are in contact with each other. Thus, the movement of the base 4 in the negative direction of the X axis can be restricted.

[0123] The two fifth through holes 7101 are provided in a region facing the two first hooking portions 41 .

[0124] The two protrusions 712 correspond one-to-one to the two sixth through holes 7102. Each protrusion 712 is provided at a position covering a portion of the corresponding sixth through hole 7102. Each protrusion 712 protrudes from the bottom plate body 710. More specifically, each protrusion 712 protrudes in the positive direction of the Y axis.

[0125] The two protrusions 712 correspond to the two bases 4 one-to-one. Each protrusion 712 is inserted into the corresponding concave portion 431e of the base 4. In the X-axis direction, the inner surfaces of the protrusion 712 and the concave portion 431e contact each other. Thus, the movement of the base 4 in the negative direction of the X-axis can be restricted.

[0126] like Figure 3 As shown, the two sixth through holes 7102 respectively include bolt holes for passing the fastening members 110 (bolts) for connecting the base 7 and the moving device 9 .

[0127] The side plate 72 includes a side plate body 721 and a fourth hook portion 722 .

[0128] The side plate body 721 is in a plate shape and protrudes from the bottom plate body 710 in the thickness direction (in the positive direction of the Y axis) of the bottom plate body 710. The thickness direction of the side plate body 721 is along the X axis direction.

[0129] The shape of the fourth hook portion 722 is plate-like. The fourth hook portion 722 protrudes from the top end (top end on the positive side of the Y axis) of the side plate body 721 in the negative direction of the X axis. The thickness direction of the fourth hook portion 722 is along the Y axis direction. The second hook portion 42 of each of the two bases 4 is hooked to the fourth hook portion 722. The second hook portion 42 is hooked to the fourth hook portion 722 with elastic deformation. That is, the second hook portion 42 is snap-fitted with the fourth hook portion 722.

[0130] The connection between the base 7 and the fixing part F1 is achieved simply by hooking the base 7 and the fixing part F1 (the first hook part 41 and the second hook part 42). Therefore, compared with the case where the base 7 and the fixing part F1 are connected using a fastening member such as a bolt, connection and disconnection are simple.

[0131] The side plate 72 has two through holes 73 (seventh through holes). The two through holes 73 correspond to the two bases 4 one-to-one. Each through hole 73 is provided in a region opposite to the second hook portion 42 of the corresponding base 4. In addition, the two through holes 73 are provided across the side plate body 721 and the fourth hook portion 722.

[0132] (8) Installation of the base unit on a mobile device

[0133] like Figure 3 As shown, the base 7 is fixed to the mobile device 9. The base 7 is fixed to the mobile device 9 using, for example, two fastening members 110. That is, the mobile device 9 has two through holes at positions overlapping with the two sixth through holes 7102 of the base 7, and the fastening members 110 are passed through the through holes of the mobile device 9 and the sixth through holes 7102 overlapping with the through holes. In addition, a washer 120 and a nut 130 are attached to each fastening member 110, for example.

[0134] (9) Removal of the base from the base

[0135] Two bases 4 are mounted on the base 7. Here, focus on one of the two bases 4, and refer to Figure 12 to Figure 14 An example of the procedure for removing the base 4 from the base 7 is described. Fig.12 , Fig.13 , the base 7 and the base 4 are each partially cross-sectionally shown.

[0136] First, if Fig.12As shown, the operator passes a tool 140 such as a flat-blade screwdriver through the through hole 73 of the base 7. The through hole 73 is opposite to the second hook portion 42 in the X-axis direction. Then, the operator performs an operation of pushing the second hook portion 42 using the tool 140. That is, the operator performs an operation of pushing the second hook portion 42 in the negative direction of the X-axis. As a result, the second hook portion 42 is elastically deformed, and the second hook portion 42 is displaced in the negative direction of the X-axis. As a result, the hooking of the second hook portion 42 and the fourth hook portion 722 is released. In more detail, as Fig.13 As shown, the base 4 is pressed by the tool 140 and rotates around the contact point between the first hook portion 41 and the third hook portion 711 .

[0137] After that, the operator separates the first hook portion 41 from the third hook portion 711, and pulls out the first hook portion 41 from the fifth through hole 7101 provided with the third hook portion 711. Fig.14 As shown, the base 4 is removed from the base 7 .

[0138] (10) Installation of the base to the base

[0139] The base 4 can be mounted on the base 7 by the reverse procedure of the procedure for removing the base 4 from the base 7. Fig.12 , Fig.13 An example of a procedure for attaching the susceptor 4 to the base 7 will be described.

[0140] like Fig.13 As shown, the first hook portion 41 of the base 4 is inserted into the fifth through hole 7101 and arranged at a position in contact with the third hook portion 711 from the negative side of the Y axis. At this time, the orientation of the base 4 becomes an orientation that is rotated around the contact point between the first hook portion 41 and the third hook portion 711 compared to when the base 4 is mounted on the base 7.

[0141] In the state where the first hook portion 41 is hooked on the third hook portion 711 of the base 7, the fixing portion F1 is rotated around the first hook portion 41, thereby the second hook portion 42 can be hooked on the fourth hook portion 722 of the base 7. That is, the operator rotates the fixing portion F1 so that the fixing portion F1 is automatically rotated. Fig.13 Status like Fig.12 As a result, the second hook portion 42 contacts the fourth hook portion 722. More specifically, the claw portion 422 of the second hook portion 42 contacts the fourth hook portion 722. The second hook portion 42 receives a reaction force in the negative direction of the X-axis from the fourth hook portion 722 and elastically deforms, and the claw portion 422 of the second hook portion 42 passes over the fourth hook portion 722. Therefore, as Fig.12 As shown, the fourth hook portion 722 moves to between the claw portion 422 and the stopper 44 .

[0142] The second hook portion 42 moves in a predetermined direction (a direction along the negative direction of the Y axis) and is hooked on the fourth hook portion 722 of the base 7. The stopper 44 restricts the second hook portion 42 hooked on the fourth hook portion 722 of the base 7 from moving in the predetermined direction. That is, after the second hook portion 42 is hooked on the fourth hook portion 722, even if a force in a direction to move the second hook portion 42 in the predetermined direction is applied to the fixing portion F1, the stopper 44 can hit the fourth hook portion 722 to hinder the movement of the second hook portion 42.

[0143] As described above, the elastic modulus of the second hook portion 42 is smaller than the elastic modulus of the first hook portion 41. Therefore, when the base 4 is mounted on the base 7, after the first hook portion 41 is hooked on the base 7, the second hook portion 42 is elastically deformed and hooked on the base 7. In addition, when the base 4 is removed from the base 7, after the second hook portion 42 is elastically deformed and removed from the base 7, the first hook portion 41 is removed from the base 7. Thus, the removal and installation operations are facilitated.

[0144] (11) Current collector replacement steps

[0145] Next, refer to Figure 12 to Figure 14 An example of a replacement procedure of the current collector 2 will be described. The replacement procedure of the current collector 2 includes a work of disassembling the structure of the current collector device 1 and a work of assembling the structure of the current collector device 1.

[0146] First, the operation of disassembling the structure of the current collector 1 will be described. Fig.12 As shown, the operator removes the cable 8 from the connector portion 3. More specifically, the operator removes the cable 8 from the connector portion 3 by pulling the second connector portion 82 of the cable 8.

[0147] Next, if Fig.12 As shown, the operator performs the operation of pushing the second hook portion 42 using the tool 140. As a result, the hooking of the second hook portion 42 and the fourth hook portion 722 is released, and as shown in FIG. Fig.13 As shown, the fixing portion F1 rotates around the contact point between the first hook portion 41 and the third hook portion 711 .

[0148] Afterwards, if Fig.14 As shown, the operator removes the fixing part F1 from the base 7. At this time, the fixing part F1, the arm 6 and the current collector 2 are connected as a whole. The operator moves the fixing part F1, the arm 6 and the current collector 2 to a place where the operation is easy. Fig.14 As shown, the operator removes the current collector 2 from the second mounting portion 67 .

[0149] The above is the operation of disassembling the structure of the current collector 1. Next, the operator performs the operation of assembling the structure of the current collector 1. The operation of assembling the structure of the current collector 1 includes the operation of mounting the replacement current collector 2 on the second mounting portion 67. The operation of assembling the structure of the current collector 1 is performed in the reverse order of the operation of disassembling the structure of the current collector 1.

[0150] In the work of assembling the structure of the current collector 1, first, Fig.13 As shown in FIG. 1 , the operator installs the replacement current collector 2 on the second installation portion 67. Next, as shown in FIG. Fig.13 As shown in FIG. 1 , the operator hooks the first hook portion 41 on the third hook portion 711 of the base 7. Furthermore, the operator rotates the fixing portion F1 around the first hook portion 41, thereby Fig.12 As shown, the second hook portion 42 is hooked on the fourth hook portion 722 of the base portion 7. Finally, the operator connects the cable 8 to the connector portion 3. The above is the work of assembling the structure of the current collector 1.

[0151] As described above, the current collector 2 can be replaced without removing the base 7 from the mobile device 9. Furthermore, since the fixing portion F1 can be removed from the base 7 by a simple operation of pressing the second hook portion 42, the current collector 2 can be easily replaced.

[0152] In addition, the operator can replace the current collector 2 after moving the fixing portion F1, the arm 6, and the current collector 2 to a place where the operation is easy. Specifically, the current collector 2 can be pulled out from the second mounting portion 67 after being separated from the trolley wire T1. Therefore, when the current collector 2 is pulled out from the second mounting portion 67, interference between the current collector 2 and the trolley wire T1 can be suppressed.

[0153] (12) Steps for holding the cable on the arm

[0154] The two arms 6 hold corresponding cables 8. The cables 8 electrically connect the current collector 2 to the mobile device 9. The first surface 64a of the arm 6, the first rib 61, the two second ribs 62, the third rib 63 and the through hole 641 are a fixing structure 600 for fixing the cables 8 (see FIG. Figure 4 ).

[0155] The cable 8 can be held on the arm 6 when the arm 6 is mounted on the fixing portion F1 and the current collector 2 is mounted on the arm 6. The cable 8 can be held on the arm 6 when the arm 6 is separated from at least one of the fixing portion F1 and the current collector 2.

[0156] Below, refer to Figure 8 , Fig. 9An example of a procedure for holding the cable 8 on the arm 6 will be described.

[0157] The operator first inserts the cable 8 into the through hole 641 of the arm body 64. The first end of the cable 8 passes through the through hole 641 and is led out to the second surface 64b side of the arm body 64 (see Figure 3 ). The second end of the cable 8 is arranged on the first surface 64 a side of the arm body 64 .

[0158] Next, the operator arranges the portion of the cable 8 on the first surface 64 a side (including the parts 80 b to 80 e of the cable 8 ) on the positive side of the Y axis with respect to the first rib 61 .

[0159] Furthermore, the operator moves the portion of the cable 8 on the first surface 64a side in the negative direction of the Y axis. Figure 8 That is, the operator passes the cable 8 through the gap between the third rib 63 and the second rib 62a, and Figure 8 As shown in FIG. 8 , a portion 80b of the cable 8 is disposed between the third rib 63 and the first surface 64a. Figure 8 As shown, the operator places the portion 80c of the cable 8 between the second rib 62a and the wall 65. In addition, the operator bends the portion 80d of the cable 8 around the first rib 61 and places the portion 80d of the cable 8 on the negative side of the Z axis relative to the first rib 61. Figure 8 As shown, the worker places a part 80 e of the cable 8 between the second rib 62 b and the wall portion 65 .

[0160] The parts 80b, 80c, 80d, and 80e of the cable 8 are arranged in this order along the X-axis direction.

[0161] In order to arrange the part 80d of the cable 8 around the first rib 61, the distance from the first rib 61 to each of the two second ribs 62 is preferably, for example, 0.9 to 1.2 times the width of the cable 8. In order to arrange the part 80d of the cable 8 around the first rib 61, it is preferable that the first rib 61 is provided at a position where it can be visually recognized through the gap between the two second ribs 62 as described above.

[0162] Next, the operator pushes the portion 80d of the cable 8 through the gap between the two second ribs 62 (via the gap) to insert the portion 80d of the cable 8 between the first rib 61 and the first surface 64a. For example, the operator inserts a finger or a tool into the gap between the two second ribs 62, pushes the portion 80d of the cable 8 with the finger or the tool, and thereby inserts the portion 80d of the cable 8 between the first rib 61 and the first surface 64a. Fig. 9As shown, the bending of the part 80d of the cable 8 is eliminated. The direction in which the operator pushes the part 80d of the cable 8 is the positive direction of the Z axis ( Figure 8 in the direction of arrow P1).

[0163] Through the above steps, the cable 8 can be held by the arm 6 .

[0164] Here, the cable 8 is pressed between the first surface 64a and the first rib 61. More specifically, a portion 80d of the cable 8 is pressed between the first surface 64a and the first rib 61. That is, the diameter of the cable 8 is the same as or slightly smaller than the distance between the first surface 64a and the first rib 61, and the cable 8 is fixed between the first surface 64a and the first rib 61 in a slightly compressed manner. Therefore, the cable 8 is not easy to move in the extension direction of the cable 8. The movement of the cable 8 in the extension direction of the cable 8 refers to, for example, a situation equivalent to the following: the portion 80d of the cable 8 that was between the first rib 61 and the first surface 64a at the moment before the movement moves to a position between the second rib 62a and the wall portion 65, or a position between the second rib 62b and the wall portion 65, etc.

[0165] For example, even if the portion 80a on the second surface 64b side of the cable 8 (see Fig. 9 ) is pulled, the cable 8 is not easy to move in the direction of the pulling force. In addition, for example, the situation in which the cable 8 moves along the extension direction of the cable 8 due to its own weight can be suppressed.

[0166] If the cable 8 does not move in the extending direction, the length L5 of the cable 8 from the through hole 641 to the connector portion 3 (see Figure 2 Therefore, the weight of the cable 8 from the through hole 641 to the connector part 3 is also constant.

[0167] Therefore, it is possible to prevent the current collector 2 from tilting due to the weight of the cable 8 due to the increase in the length L5 (that is, the cable 8 is loosened). Fig.12 ) when the contact area is reduced.

[0168] Furthermore, when the cable 8 is pulled in the direction that reduces the length L5 (the positive direction of the X axis), it is possible to suppress the negative force of the Y axis from being applied to the current collector 2 via the cable 8. This can suppress the current collector 2 from being displaced in the negative direction of the Y axis and separated from the sliding wire T1.

[0169] In addition, the cable 8 is inserted between the wall portion 65 and the two second ribs 62. As a result, it is possible to suppress the displacement of the cable 8 in the relative direction (Z-axis direction) between the wall portion 65 and the two second ribs 62. In particular, when the negative direction of the Z-axis coincides with the direction of gravity, it is possible to suppress the displacement of the cable 8 due to its own weight. Therefore, it is possible to suppress the cable 8 from contacting the surrounding structure (another cable 8, etc.).

[0170] The cable 8 is inserted between the first surface 64a and the third rib 63. This can prevent the cable 8 from being displaced away from the first surface 64a. Therefore, the cable 8 can be prevented from contacting the surrounding structure (such as the trolley wire T1).

[0171] (13) First guide portion and second guide portion

[0172] like Fig.10 As shown, the base 4 of the fixing portion F1 has a first guide portion 47. The arm 6 has a second guide portion 68. The first guide portion 47 and the second guide portion 68 are structures for restricting the direction of the arm 6 from deviating from a predetermined direction.

[0173] The first guide portion 47 is a groove portion, and the second guide portion 68 is a convex portion inserted into the groove portion.

[0174] The groove (first guide portion 47) is concave toward the negative direction of the Y axis. The negative side of the Y axis in the groove corresponds to the inner side of the groove. The groove becomes narrower as it moves toward the inner side. More specifically, the groove is formed in a V-shape.

[0175] The convex portion (second guide portion 68) is opposite to the groove portion. The convex portion is convex in the negative direction of the Y axis. The width of the convex portion is narrower as it approaches the negative side of the Y axis. More specifically, the convex portion is formed in a V-letter shape.

[0176] The compression spring S1 applies a spring force to the arm 6 at the right side (negative side of the X-axis) of the first mounting portion 66, which is the rotation center of the arm 6. In addition, the second guide portion 68 is provided at the left side of the first mounting portion 66. Therefore, when the compression spring S1 pushes the arm 6, the second guide portion 68 moves toward the first guide portion 47. In other words, when the compression spring S1 pushes the arm 6, the second guide portion 68 moves in the negative direction of the Y-axis.

[0177] Fig.10 This indicates a state in which the orientation of the arm 6 is correct. At this time, the tip 471 on the negative side of the Y axis in the first guide portion 47 and the tip 681 on the negative side of the Y axis in the second guide portion 68 face each other in the Y axis direction.

[0178] The holder 5 can be formed by the cylindrical portion 45 of the base 4 (see Figure 3) as the axis. The arm 6 can rotate with the holder 5 about the cylindrical portion 45 as the axis. By rotating the arm 6 around an axis parallel to the Y axis, as shown in FIG. Fig.11 As shown in FIG. 1 , it is assumed that the direction of the arm 6 is offset. In this case, the top end 471 of the first guide portion 47 and the top end 681 of the second guide portion 68 are opposite to each other in a direction intersecting the Y axis. Furthermore, the top end 681 of the second guide portion 68 contacts the inclined surface of the first guide portion 47. The spring force applied to the arm 6 by the self-compression spring S1 is used to apply (receive) force to the second guide portion 68 in the negative direction of the Y axis. Therefore, the arm 6 is moved along the inclined surface of the first guide portion 47 (along the Y axis). Fig.11 Finally, the arm 6 rotates until the top 681 of the second guide portion 68 and the top 471 of the first guide portion 47 are opposite to each other. Fig.10 As shown, the direction of the arm 6 becomes the correct direction. In this way, the deviation of the direction of the arm 6 can be corrected using the spring force of the compression spring S1.

[0179] (Variation Example)

[0180] The following are modified examples of the embodiments. The following modified examples can also be implemented in appropriate combinations. The structure of the above-mentioned embodiment is referred to as a basic example.

[0181] (Variant 1)

[0182] Below, use Fig.15 , Fig.16 A description will be given of a current collector 1A according to Modification 1. The same components as those of the basic example are denoted by the same reference numerals and description thereof will be omitted.

[0183] The current collector 1A of the first modification is different from the basic example in that it includes three current collectors 2, three arms 6, three fixing portions F1, three compression springs S1, and three cables 8. It is also different from the basic example in that each current collector 2 has two contact portions 21 and two covers 22.

[0184] In addition, the base 7 has a structure for hooking and installing the three fixing parts F1 respectively. Specifically, the base 7 has three third hook parts 711, and the first hook part 41 of the corresponding fixing part F1 is hooked to each third hook part 711. In addition, the base 7 has a fourth hook part 722, and the second hook part 42 of each of the three fixing parts F1 is hooked to the fourth hook part 722. The base 7 has three through holes 73 respectively facing the three second hook parts 42.

[0185] The three current collectors 2 have a common structure. Here, the description will be made focusing on one current collector 2.

[0186] The current collector 2 has two contact portions 21 , two covers 22 , a penetration portion 23 (first penetration portion), a shaft portion 24 , a connecting shell 25 , a second penetration portion 26 , and two shaft portions 27 .

[0187] The structure of the penetration portion 23 is the same as that of the basic example.

[0188] The shaft portion 24 rotatably connects the connection housing 25 to the penetration portion 23. That is, the connection housing 25 is rotatable about the shaft portion 24.

[0189] The longitudinal direction of the connection housing 25 is along the X-axis direction. The connection housing 25 has third mounting portions 251 at both ends in the longitudinal direction. That is, the connection housing 25 has two third mounting portions 251.

[0190] The structure of each of the two third mounting portions 251 is the same as that of the second mounting portion 67 of the arm 6. That is, the third mounting portion 251 has a mounting hole 2511.

[0191] The structure of each of the two second penetration portions 26 is the same as that of the penetration portion 23. The two second penetration portions 26 correspond to the two covers 22 one-to-one. Each second penetration portion 26 connects the corresponding cover 22 and the connection housing 25.

[0192] More specifically, the second penetration portion 26 includes a connecting portion 261 , a column portion 262 , and two protruding pieces 263 .

[0193] The connection part 261 is connected to the cover 22. More specifically, the connection part 261 is connected to the cover 22 by passing the shaft 27 through through holes provided in the connection part 261 and the cover 22. The cover 22 can rotate together with the contact part 21 around the connection part (shaft 27) with the connection part 261.

[0194] The column 262 is cylindrical in shape. The length direction of the column 262 is along the Y-axis direction. The column 262 protrudes from the connecting portion 261. The column 262 has a slit 2620 at the top end (negative side of the Y-axis) on the side opposite to the connecting portion 261. The slit 2620 is a concave portion that is concave from the top end of the column 262 toward the connecting portion 261 side.

[0195] The two protrusions 263 protrude from the top end of the column 262 on the side opposite to the connecting portion 261 in a direction intersecting the length direction of the column 262. The protrusion direction (left direction) of one of the two protrusions 263 is opposite to the protrusion direction (right direction) of the other protrusion 263. A slit 2620 is formed between the two protrusions 263.

[0196] The width of the top end portion of the second through-hole 26, where two protrusions 263 are provided, is larger than the width of the column portion 262. By clamping the two protrusions 263 from both sides, the second through-hole 26 is elastically deformed so as to narrow the width of the slit 2620, and the width of the top end portion of the second through-hole 26 is reduced. In this state, by inserting the top end portion of the second through-hole 26 into the mounting hole 2511, the cover 22 is mounted on the connecting housing 25 via the second through-hole 26.

[0197] In this modification 1, the structure consisting of the second penetration portion 26, the cover 22 and the contact portion 21 can be disassembled and replaced by pulling out the second penetration portion 26 from the mounting hole 2511 of the connecting housing 25. In addition, by pulling out the penetration portion 23 from the mounting hole 671 of the arm 6, the current collector 2 can also be disassembled and replaced.

[0198] (Other Modifications of Embodiment)

[0199] Other modified examples of the embodiment are listed below.

[0200] In the structure of the recessed part and the convex part in the basic example, the recessed part and the convex part may be interchanged. For example, in the basic example, the first guide part 47 is a groove part (recessed part) and the second guide part 68 is a convex part inserted into the groove part, but the second guide part 68 may be a groove part (recessed part) and the first guide part 47 may be a convex part inserted into the groove part. In addition, for example, in the basic example, the cylindrical part 45 (convex part) of the base 4 is inserted into the recessed part 512 of the holder 5, but the convex part of the holder 5 may be inserted into the recessed part of the base 4 on the contrary.

[0201] In the basic example, the second hook portion 42 is configured to be released from the base 7 by pushing the second hook portion 42. In contrast, in a modified example, at least one of the first hook portion 41 and the second hook portion 42 may be configured to be released from the base 7 by pushing the at least one. Therefore, for example, the first hook portion 41 may be configured to have elasticity.

[0202] In the basic example, the second hooking portion 42 is pushed and elastically deformed, and the hooking between the second hooking portion 42 and the base 7 is released. In contrast, in a modified example, at least one of the first hooking portion 41 and the second hooking portion 42 may be configured to be pushed and elastically deformed, and the hooking between the at least one and the base 7 may be released. Therefore, for example, the first hooking portion 41 may be pushed and elastically deformed through the fifth through-hole 7101 provided in the area of ​​the base 7 facing the first hooking portion 41, and the hooking between the first hooking portion 41 and the base 7 may be released. Therefore, the base 7 may have a through-hole in the area facing at least one of the first hooking portion 41 and the second hooking portion 42.

[0203] The current collector 1 of the basic example includes two current collectors 2, two connector portions 3, two fixing portions F1, two compression springs S1, two arms 6, a base portion 7, and two cables 8. However, the number of each of the above components can be changed appropriately.

[0204] The arm 6 of the basic example has two second ribs 62. However, the number of the second ribs 62 may be one or three or more.

[0205] In the basic example, a plurality of components described as mutually independent components may be appropriately constituted as one component. For example, the holder 5 and the base 4 may be constituted by one component.

[0206] In the basic example, the plurality of structures described as one member may be manufactured as separate members and then connected. For example, the wall portion 65 and the first rib 61 may be manufactured as separate members and then connected.

[0207] The first rib 61 may not protrude from the wall portion 65 but may protrude from a columnar member protruding from the first surface 64 a , for example.

[0208] The first hook portion 41 and the second hook portion 42 may be formed on the same surface. For example, the first hook portion 41 and the second hook portion 42 may be formed on the bottom portion 431 of the base 4.

[0209] The current collector 1 may include a tension spring instead of the compression spring S1. The tension spring applies force to the arm 6 in a direction to displace the second mounting portion 67 of the arm 6 in the positive direction of the Y axis. This ensures contact pressure between the current collector 2 and the trolley wire T1.

[0210] (Summarize)

[0211] According to the above-described embodiments and the like, the following aspects are disclosed.

[0212] The current collector 1, 1A of the first embodiment transmits electric power from the trolley wire T1 to the mobile device 9. The current collector 1, 1A includes an arm 6 that supports the current collector 2. The current collector 2 is in contact with the trolley wire T1. The arm 6 has a first surface 64a, a first rib 61, and a through hole 641. The first surface 64a is in contact with a cable 8 for electrically connecting the current collector 2 to the mobile device 9. The first rib 61 sandwiches the cable 8 between the first rib 61 and the first surface 64a, and holds the cable 8. The through hole 641 allows the cable 8 to pass through.

[0213] According to the above configuration, the cable 8 is sandwiched between the first rib 61 and the first surface 64a and passed through the through hole 641, thereby suppressing positional deviation of the cable 8. Therefore, it is possible to suppress the cable 8 from becoming loose or being pulled.

[0214] In the current collector 1 or 1A of the second embodiment, in addition to the first embodiment, the cable 8 is pressed between the first surface 64 a and the first rib 61 .

[0215] According to the above-mentioned configuration, positional deviation of the cable 8 can be further suppressed.

[0216] In the current collector 1 or 1A of the third embodiment, in addition to the first or second embodiment, the arm 6 further includes a wall portion 65 protruding from the first surface 64 a in the normal direction of the first surface 64 a . The first rib 61 protrudes from the wall portion 65 .

[0217] According to the above-described structure, the cable 8 can be held on the surface of the wall portion 65 .

[0218] In the fourth embodiment, the current collector 1 or 1A is configured according to the third embodiment, wherein the longitudinal direction of the wall portion 65 is along the extending direction of the cable 8 between the first surface 64 a and the first rib 61 .

[0219] According to the above-described configuration, the cable 8 can be arranged along the longitudinal direction of the wall portion 65 .

[0220] In the fifth embodiment, the current collector 1 or 1A is configured according to the third or fourth embodiment, wherein the arm 6 further includes a second rib 62 protruding from the first surface 64a in the normal direction of the first surface 64a. The second rib 62 faces the wall 65. The cable 8 is inserted between the wall 65 and the second rib 62.

[0221] According to the above-described configuration, it is possible to suppress the cable 8 from being displaced in the direction opposite to the wall portion 65 (the negative direction of the Z axis).

[0222] In the sixth aspect, the current collector 1 or 1A is configured according to the fifth aspect, wherein the arm 6 has two second ribs 62. The first rib 61 is provided at a position where it can be visually recognized through a gap between the two second ribs 62.

[0223] According to the above configuration, by passing a part of the cable 8 through the gap between the two second ribs 62 , the cable 8 can be easily inserted between the first rib 61 and the first surface 64 a .

[0224] In the current collector device 1 or 1A of the seventh embodiment, in addition to the sixth embodiment, a distance L1 between the two second ribs 62 at a height position of the first rib 61 is longer than a shortest distance L2 between the wall portion 65 and the two second ribs 62 .

[0225] According to the above-mentioned structure, it is easy to pass a part of the cable 8 through the gap between the two second ribs 62 .

[0226] In the eighth embodiment, the current collector 1 or 1A is configured according to any one of the first to seventh embodiments, wherein the arm 6 further includes a third rib 63 facing the first surface 64a. The cable 8 is inserted between the first surface 64a and the third rib 63.

[0227] According to the above-described configuration, it is possible to suppress the cable 8 from being displaced in a direction away from the first surface 64 a .

[0228] In addition, the current collector device 1, 1A of the ninth embodiment is provided with a fixing portion F1 and a compression spring S1 in addition to any one of the first to eighth embodiments. The fixing portion F1 has a coupling portion 52 to which the arm 6 is mounted. The arm 6 also has: a first mounting portion 66 mounted on the fixing portion F1; a second mounting portion 67 to which the current collector 2 is mounted; and a second surface 64b which is a surface on the side opposite to the first surface 64a. The arm 6 can rotate around the first mounting portion 66. The compression spring S1 is sandwiched between the fixing portion F1 and the area between the first mounting portion 66 and the second mounting portion 67 in the second surface 64b.

[0229] According to the above configuration, the contact pressure between the current collector 2 and the trolley wire T1 can be ensured by the spring force of the compression spring S1. In addition, the current collector 1, 1A can be easily miniaturized compared to the case where a tension spring is used instead of the compression spring S1.

[0230] In the current collector device 1 or 1A of the tenth embodiment, in addition to the ninth embodiment, the fixing portion F1 further includes a first guide portion 47, and the arm 6 further includes a second guide portion 68. The first guide portion 47 and the second guide portion 68 restrict the direction of the arm 6 from deviating from a predetermined direction. One of the first guide portion 47 and the second guide portion 68 is a groove portion, and the other is a protrusion inserted into the groove portion.

[0231] According to the above-mentioned structure, it is possible to suppress deviation of the orientation of the arm 6 .

[0232] In the current collector device 1 or 1A of the eleventh embodiment, in addition to the tenth embodiment, when the compression spring S1 presses the arm 6, the second guide portion 68 moves toward the first guide portion 47. The groove portion has a narrower width toward the inner side.

[0233] According to the above-described configuration, the deviation in the orientation of the arm 6 can be corrected using the spring force of the compression spring S1 .

[0234] In addition, the current collector device 1 or 1A of the twelfth embodiment is provided with a fixing portion F1 in addition to any one of the first to eleventh embodiments. The arm 6 further includes a first mounting portion 66 mounted on the fixing portion F1 and a second mounting portion 67 to which the current collector 2 is mounted. The arm 6 is rotatable about the first mounting portion 66. The distance L3 between the first mounting portion 66 and the first rib 61 is shorter than the distance L4 between the first mounting portion 66 and the second mounting portion 67.

[0235] According to the above configuration, since the distance L3 between the first rib 61 and the first mounting portion 66 as the rotation center is relatively short, the displacement of the first rib 61 can be reduced during the operation of inserting the cable 8 between the first rib 61 and the first surface 64a. Therefore, the operation is easy.

[0236] Furthermore, in the current collector 1 or 1A of the thirteenth aspect, in addition to any one of the first to twelfth aspects, a through hole 641 through which the cable 8 is passed is provided in the first surface 64a.

[0237] According to the above configuration, the cable 8 can be arranged in a region overlapping the arm 6 when viewed from a direction facing the first surface 64a. Therefore, the possibility of the cable 8 contacting the surrounding structure of the current collector 1 or 1A can be reduced.

[0238] The structures other than the first embodiment are not essential to the current collectors 1 and 1A and can be omitted as appropriate.

[0239] Furthermore, the arm 6 of the fourteenth aspect is used for the current collector 1 or 1A of any one of the first to thirteenth aspects.

[0240] According to the above-mentioned configuration, positional deviation of the cable 8 can be suppressed.
