  However, the techniques described in Patent Documents 1 and 2 do not connect a wiring cable to a terminal block (a movable terminal block in Cited Document 1 and a female type in Cited Document 2). Here, if the wiring cable is connected to the terminal block, the wiring cable may be loosened when the terminal block is slid, which may cause entanglement with other components. Furthermore, if it is entangled with other parts, the terminal block may not be pulled out or the wiring cable may be detached from the terminal block.

  As described above, in the technologies described in Patent Documents 1 and 2, if the wiring cable is connected to the terminal block, the above-described problem occurs when the terminal block is pulled out, and it is difficult to smoothly pull out the terminal block. There is a technical problem.

  Therefore, in view of the above-described conventional situation, the object of the present invention is to move a member that can improve workability during installation by smoothly pulling out the terminal block when pulling out the terminal block outside the apparatus. An object is to provide a mechanism and a power storage device.

  In order to achieve the above object, a member moving mechanism according to the present invention includes a moving means for moving a predetermined first member from the inside of an apparatus including the predetermined second member to the outside, and the first And a supporting means for supporting the string-like member connecting the second member, and after detecting the separation of the first member from a predetermined region inside the device, at least a part of the first member is While staying inside the apparatus, the string-like member at the position of the first member where the movement by the moving means is completed comes into contact with the inside of the apparatus only at the second member and the supporting means. Positioning means for positioning the support means.

  In order to achieve the above object, a power storage device according to the present invention includes the member moving mechanism and the string-like member.

  According to the present invention, when the terminal block is pulled out of the apparatus, the workability at the time of installation can be improved by smoothly pulling out the terminal block.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First embodiment)
An embodiment (first embodiment) of the present invention will be described with reference to FIGS. 1 and 2. 1 and 2 show an internal configuration of a power storage device 100 including a member moving mechanism 110 according to the present embodiment (first embodiment), and show first and second states of the member moving mechanism 110. FIG. It is an internal block diagram.

  In the present embodiment, the first state refers to a state where the terminal block 120 is housed inside the power storage device 100. The second state refers to a state where the terminal block 120 is pulled out to a work position outside the power storage device 100.

  Referring to FIGS. 1 and 2, the power storage device 100 includes a member moving mechanism 110 and a device internal cable (string member) 170. The member moving mechanism 110 includes a moving unit 111, a support unit 130, and a positioning unit 150.

  The moving means 111 moves the terminal block (first member) 120 from the inside of the power storage device (device) 100 including the breaker (second member) 160 to the outside. The support means 130 supports the device internal cable 170 that connects the terminal block 120 and the breaker 160. The positioning unit 150 detects the detachment from the predetermined area inside the power storage device 100 of the terminal block 120 and then supports the support unit 130 while the at least part of the terminal block 120 stays inside the power storage device 100. Position it at the position. Here, the predetermined position is a position where the device internal cable 170 at the position of the terminal block 120 where the movement is completed by the moving means 111 contacts the inside of the power storage device 100 only at the breaker 160 and the support means 130.

  Here, the case where the terminal block 120 is detached from the predetermined area inside the power storage device 100 is, for example, a case where the operator pulls the terminal block 120 to the working position. At this time, the device internal cable 170 connected to the terminal block 120 may be loosened. For this reason, it may be entangled with other parts. Furthermore, if it is entangled with other parts, the terminal block 120 may not be pulled out, or the device internal cable 170 may be disconnected from the terminal block 120.

  On the other hand, as shown in FIG. 2, when the terminal block 120 is moved away from the storage position, the member moving mechanism 110 has the device internal cable 170 at the position of the terminal block 120 where the movement is completed by the moving means 111. Only the breaker 160 and the support means 130 can be located at a position where they contact each other inside the power storage device 100. The member moving mechanism 110 makes it easy to pull the device internal cable 170 by the terminal block 120 without causing the device internal cable 170 to interfere with other components when the terminal block 120 moves away from the storage position. The member moving mechanism 110 can smoothly pull out the terminal block 120 when the operator pulls the terminal block 120 to the working position.

  Therefore, according to this embodiment, when pulling out the terminal block 120 to the outside of the power storage device 100, the workability at the time of installation can be improved by smoothly pulling out the terminal block 120.

(Second Embodiment)
Another embodiment (second embodiment) of the present invention will be described with reference to FIGS. First, the structure of the member moving mechanism 210 of this embodiment and the electrical storage apparatus 200 which comprises this member moving mechanism 210 is demonstrated using FIG. FIG. 3 is an internal configuration diagram illustrating an internal configuration of the power storage device 200 including the member moving mechanism 210 according to the present embodiment (second embodiment), and illustrating a first state of the member moving mechanism 210. In the present embodiment, the first state refers to a state before the device external cable 271 is connected to the terminal block 210 and a state in which the terminal block 210 is housed inside the power storage device 200.

  Referring to FIG. 3, the power storage device 200 includes a member moving mechanism 210 and a device internal cable (cable) 270. The member moving mechanism 210 includes a terminal block 220, support means 230, detection means 240, and positioning means 250.

  Since the terminal block 220 is a well-known technique, a specific description thereof is omitted, but it has a device internal cable terminal and a device external cable terminal (not shown). The terminal block 220 connects the device internal cable 270 and the device external cable 271 to these terminals, and connects an external distribution board (not shown) and the breaker 260.

  In the present embodiment, the terminal block 220 is movable between a storage position inside the power storage device 200 and a work position outside the power storage device 200. In order to enable the terminal block 220 to move, the member moving mechanism 210 includes a rail 211 and a handle 212. Rail 211 is formed in a plate shape and is provided to be slidable along the width direction of power storage device 200. A terminal block 220 is placed on the top surface of the rail 211. A handle 212 is provided on a side surface of the rail 211. As a result, the operator can grasp the handle 212 and pull out the rail 211. Since the terminal block 220 is placed on the rail 211 as described above, the terminal block 220 can be pulled out to the working position by pulling out the rail 211. Further, by returning the rail 211 to the original position, the terminal block 220 can be returned to the storage position. Note that the storage position refers to a position where the terminal block 220 is stored in a predetermined position inside the power storage device 200. The work position refers to a position where the terminal block 220 is pulled out of the power storage device 200.

  The member moving mechanism 210 includes a support portion (support means) 230 that supports the device internal cable 270. The support part 230 is formed in a cylindrical shape. The support unit 230 inserts the device internal cable 270 therein and supports the device internal cable 270.

  The support unit 230 supports the device internal cable 270 so as to be slidable inside. The device internal cable 270 is supported with play in the support portion 230 without being completely restrained by the support portion 230. Therefore, as described later, when the support section 230 is positioned on a straight line connecting the terminal block 220 and the breaker 260, when the terminal block 220 is pulled out by the user, the device internal cable 270 is stretched in a straight line. It is possible to cross.

  The support part 230 supports the central part of the equipment internal cable 270. For this reason, the support part 230 can push up and pull down the apparatus internal cable 270 with good balance.

  In addition, the member moving mechanism 210 includes a detection unit 241 and a detection sensor 242 as detection means 240 in order to detect whether or not the terminal block 220 is located at the storage position. The detection unit 241 is placed on the rail 211. The detection sensor 242 is provided on the wall surface of the housing. The detection unit 241 is located at a position detected by the detection sensor 242 when the terminal block 220 is located at the storage position. On the other hand, the detection unit 241 is located at a position that is not detected by the detection sensor 242 when the terminal block 220 moves away from the storage position. That is, the detection sensor 242 detects whether or not the terminal block 220 is located at the storage position.

  Further, the member moving mechanism 210 includes an elevating mechanism (positioning means) 250 that positions the support portion 230. In the present embodiment, the elevating mechanism 250 includes a control board 251, a stepping motor 252, a pulley 253, a belt 254, a crank 255, a rod 256, a slider 257, a slider guide 258, and a connecting member 259.

  The control board 251 is connected to the detection sensor 242 and the stepping motor 252. The control board 251 performs control to rotate the stepping motor 252 clockwise, for example, after the detection unit 241 is detected by the detection sensor 242. Further, when the detection unit 241 is not detected by the detection sensor 242, the control board 251 performs control to rotate the stepping motor 252 counterclockwise, for example. The stepping motor 252 is a well-known technique and will not be specifically described.

  A belt 254 is wound around the rotating shaft of the stepping motor 252 and the outer periphery of the pulley 253. For this reason, when the stepping motor 252 rotates, the pulley 253 rotates in conjunction with this rotation.

  One end of the crank 255 is fixed to the center of the pulley 253. The crank 255 is extended along the surface of the pulley 253. The other end of the crank 255 is located in the vicinity of the outer peripheral edge of the pulley 253. For this reason, when the pulley 253 rotates, the other end of the crank 255 moves in the vicinity of the outer peripheral edge of the pulley 253 in conjunction with this rotation.

  One end of a rod 256 is connected to the other end of the crank 255 so as to be rotatable. A slider 257 is fixed to the other end of the rod 256. The rod 256 is composed of a telescopic rod. The slider 257 is provided so as to be slidable on the slider guide 258. For this reason, when the stepping motor 252 rotates, the slider 257 moves up and down.

  A connecting member 259 is fixed to the slider 257, and the above-described support portion 230 is fixed to the connecting member 259. For this reason, when the slider 257 moves up and down, the connecting member 259 and the support portion 230 also move up and down in accordance with the lifting operation. Thereby, a part of the device internal cable 270 supported by the support unit 230 is pushed up or pulled down.

(Operation)
Next, the operation of the member moving mechanism 210 according to the present embodiment will be described with reference to FIGS. 4 to 6 show the internal configuration of the power storage device 200 including the member moving mechanism 210 according to the present embodiment (second embodiment). The second state, the third state, and the member moving mechanism 210 are shown in FIG. It is an internal block diagram which shows a 4th state.

  In the present embodiment, the second state is a state before the device external cable 271 is connected to the terminal block 220, and is a state in which the terminal block 220 is pulled out to a work position outside the power storage device 200. Say. The third state refers to a state in which the device external cable 271 is connected to the terminal block 220 drawn to the work position. The fourth state refers to a state in which the terminal block 220 to which the device external cable 271 is connected is returned to the storage position inside the power storage device 200.

  An operator holds the handle 212 and slides the rail 211. Referring to FIG. 4, the terminal block 220 placed on the rail 211 is pulled out to the working position. At this time, the detection unit 241 is separated from the detection sensor 242. The detection sensor 242 detects that the terminal block 220 has moved away from the storage position. When the detection sensor 242 detects that the terminal block 220 has moved away from the storage position, the control board 251 rotates the stepping motor 252 clockwise. When the stepping motor 252 is rotated clockwise, the slider 257 is pushed upward, and the support portion 230 is positioned on a straight line connecting the terminal block 220 and the breaker 260. Thus, the support part 230 is positioned on a straight line, and the device internal cable 270 is stretched in a straight line. For this reason, when the terminal block 220 is pulled out, the terminal block 220 can be pulled out smoothly.

  Referring to FIG. 5, device external cable 271 is connected to terminal block 220 drawn out of power storage device 200. Thus, when the device external cable 271 is connected to the terminal block 220, the terminal block 220 is pulled out of the power storage device 200, so that the work area can be enlarged. Thereby, workability | operativity can be improved.

  When the device external cable 271 is connected to the terminal block 220, the handle 212 is gripped and the rail 211 is pushed and slid to return the terminal block 220 to its original position. Referring to FIG. 6, when the terminal block 220 is returned to the original position, the terminal block 220 is returned to the inside of the power storage device 200. When the detection unit 241 is detected by the detection sensor 242, the control board 251 rotates the stepping motor 252 counterclockwise. Then, the slider 257 is pulled down. When the slider 257 is pulled down, a part of the device internal cable 270 is pulled into the space inside the power storage device 200. As described above, a part of the device internal cable 270 is pulled downward, thereby preventing the device internal cable 270 from being entangled. For this reason, when pulling out the terminal block 220 again, it becomes possible to eliminate the concern that the device internal cable 270 cannot be pulled out due to the entanglement.

  Thus, the member moving mechanism 210 can stretch the device internal cable 270 in a straight line when the operator pulls the terminal block 220 to the working position, and can smoothly pull out the terminal block 220. It becomes possible.

  Therefore, according to this embodiment, when pulling out the terminal block 220 to the outside of the power storage device 200, the terminal block 220 can be pulled out smoothly, and workability at the time of installation can be improved.
