  Hereinafter, a bus duct system according to an embodiment of the present invention will be described with reference to the drawings. The bus duct system of the present invention is not limited to the following embodiments (first to third embodiments) and other embodiments.

<< First Embodiment >>
First, the bus duct system of 1st Embodiment is demonstrated using FIGS.
As shown in FIG. 5, the bus duct system of the first embodiment includes a bus duct 10 having a housing in which a plug-in hole 31 is provided, and a branch device 20 that is detachably attached to the bus duct 10.
As will be described later, the housing of the bus duct 10 includes a pipe spacer 112 and a side plate 113 of the bus duct unit 11, and a connection side plate 123 and a connection upper and lower plate 30 of the connection unit 12, as shown in FIG. Yes.

Further, the branch device 20 is provided with a track portion 60 that indicates a track of movement of the branch device 20 with respect to the bus duct 10 when it is attached to the bus duct 10 (a predetermined position of the bus duct 10) (see FIGS. 3 and 5).
The housing of the bus duct 10 is provided with an opening / closing door 40 that opens and closes the plug-in hole 31 and a reference portion 50 that serves as a reference when the branch device 20 is moved along the track indicated by the track portion 60 ( (See FIGS. 1 and 5). The reference portion 50 is hidden in the track portion 60 when the orbit of the movement of the branching device 20 with respect to the bus duct 10 when attached to the bus duct 10 deviates from or appears to deviate from the track indicated by the track portion 60. It is formed so as to be invisible or difficult to see from the outside.

  According to the above configuration, when the orbit when attaching the branch device 20 to the bus duct 10 deviates from or is about to deviate from the orbit indicated by the orbit 60, the reference portion 50 is hidden by the orbit 60. It becomes invisible or difficult to see from outside. Therefore, the operator can determine whether or not the branching device 20 can be appropriately moved according to how the reference unit 50 is seen (that is, the attachment work of the branching device 20 is appropriately executed according to how the reference unit 50 is seen). And as a result, it helps to move the branching device properly (helps to attach the branching device 20 to the appropriate position of the bus duct 10).

  Next, each structure of the bus duct system of 1st Embodiment is demonstrated in order.

First, the configuration of the bus duct 10 will be described with reference to FIGS. 1 and 2.
As shown in FIGS. 1 and 2, the bus duct 10 has a structure in which a conductor 111a with an insulation coating is covered with a housing, and the bus duct units 11 and 11 are connected to each other via a separate connection unit 12. Is formed. That is, the bus duct 10 of the first embodiment has a configuration including a plurality of bus duct units 11 and a connection unit 12 that connects the bus duct units 11 arranged adjacent to each other.

  As shown in FIG. 2A, the bus duct unit 11 includes a three-phase insulating coated conductor 111 (insulated coated conductor 111 formed by coating a flat plate-shaped power transmission conductor 111a with an insulator). Are arranged in parallel, and pipe spacers 112 having a substantially rectangular shape in plan view are arranged on both sides in the width direction of the insulating coated conductor 111. The bus duct unit 11 includes a pair of side plates 113 and 113 each having a substantially U-shaped cross section, and a clamp member such as a bolt 114a and a nut 114b inserted into the side plate 113. It is fastened and fixed.

  The side plate 113 has a first reinforcing portion 113a extending at a substantially right angle from the sandwiched insulation-coated conductor 111 at both upper and lower ends of the side plate 113, and at the edge of the first reinforcing portion 113a. In the direction facing each other, the second reinforcing portion 113b extends substantially at a right angle to maintain the strength of the bus duct unit 11 and the bus duct 10 itself. In the bus duct unit 11, the pipe spacer 112 and the side plate 113 correspond to a housing.

Further, as shown in FIG. 2B, the connection unit 12 includes a conductive connection member 121 that electrically connects the in-phase conductors 111a and 111a of the bus duct units 11 and 11 to be connected, an insulating separator 122, A connection side plate 123 that clamps them from the outside and a pressing member 124 disposed outside the connection side plate 123 are provided, and these are fastened by a fastener 126 that is inserted through an insulating sleeve 125. The bus duct units 11 and 11 are connected to each other, and are temporarily fastened by the fastening tool 126 before the connection.
The insulating separator 122 is installed at a position that insulates between the conductors 111 a and 111 a of different phases including the conductive connecting member 121 and between the outermost conductor 111 a including the conductive connecting member 121 and the connection side plate 123.

When connecting the bus duct units 11 and 11 with the connecting unit 12 to form the bus duct 10, the end portions of the conductors 111 a and 111 a of the bus duct units 11 and 11 to be connected are inserted between the in-phase conductive connecting members 121 and 121. The bus duct side plate 113 and the connection side plate 123 are fixed with a fastening tool such as a bolt and nut, and then the temporarily fastened fastening tool 126 is fastened. Are fixed to the bus duct units 11 and 11 by screws or the like, and the open surfaces are closed to complete the connection between the bus duct units 11 and 11. At this time, a plug-in hole 31 is formed in at least one of the connection upper and lower plates 30 (in this case, the upper surface side), and the plug-in hole 31 is closed by the open / close door 40 so as to be opened and closed. In this manner, the housing of the bus duct 10 is the expansion unit expanded in the thickness direction of the bus duct in the connection unit 12 forming the peripheral portion of the plug-in hole 31 (the expansion of the left bus duct unit 11 in FIG. 1B). A portion sandwiched between the side portion 115 and the right bulging side portion 115) is formed. In the connection unit 12, the connection side plate 123, the connection upper / lower plate 30, and the opening / closing door 40 correspond to a housing.
The connection upper and lower plates 30 are configured to have a flat plate-like base portion 32 and reinforcing pieces 34 formed by bending and extending both side edges of the base portion 32 at substantially right angles.

Next, the branch device 20 will be described with reference to FIG.
As shown in FIG. 3, the branching device 20 includes a box-shaped box body 22 that supports a branching terminal 23. The box 22 has a plate-like bottom surface 22a, and side walls 22b and 22b, front walls 22c, and a rear wall 22d, which are peripheral walls, are erected from the bottom surface 22a. Is provided.

  The track portion 60 and the first fixing member 24 are provided in this order from the rear side to the middle of the branch terminal 23 on the bottom surface 22a, and the second fixing member 25 and the third fixing member 26 are provided on the front wall 22c and the rear wall 22d, respectively. Is provided. In the box 22, a terminal block 23a for fixing the branching terminal 23, a breaker 23b, and a connection conductor 23c for electrically connecting the terminal block 23a and the breaker 23b are installed. Electric power is branched from the connecting conductor 23c to the outside of the box body 22 through the breaker 23b.

  As shown in FIGS. 4A to 4C, the track portion 60 includes a flat plate-like base portion 61, and track pieces 62 and 62 formed by bending and extending both side edges of the base portion 61 at substantially right angles. have. The track piece 62 may be only on one side.

  As shown in FIG. 4B, the track pieces 62 and 62 are formed in a substantially rectangular shape as a whole, and, for example, a linear track groove 63 is formed so as to divide the center in the front-rear direction from the bottom to the top. Has been. The track piece 62 may not be substantially rectangular, and the track groove 63 may not be linear but may be a curved shape or a combined shape of a straight line and a curved line.

Further, the shape of the track groove 63 is the trajectory of the movement of the branch device 20 relative to the bus duct 10 when the branch device 20 is attached to the bus duct 10 (more specifically, the motion trajectory of the portion where the track portion 60 is provided). And, in combination with a reference portion 50, which will be described later, shows the insertion path of the branching terminal 23 to the plug-in hole 31 indirectly.) At least a part of the bus duct 10 is shown at a predetermined position. In the middle of moving the branching device 20 toward the bus duct 10 along this track, the branching terminal 23 of the branching device 20 and the housing of the bus duct 10 are designed so as not to contact each other.
As shown in FIG. 3B, the track portion 60 is displaced in the horizontal direction from the branch terminal 23 in a side view of the branch device 20. Therefore, the track groove 63 indirectly indicates an insertion track of the branch terminal 23 with respect to the plug-in hole 31. However, the present invention is not limited to this, and the track portion 60 may be installed at a position overlapping the branch terminal 23 in a side view of the branch device 20 to directly indicate the insertion track.

Next, the structure corresponding to the track portion 60 of the branching device 20 provided on the bus duct 10 side will be described.
Since the bus duct unit 11 of the bus duct 10 has a continuous housing structure with the connection side plate 123 of the connection unit 12, the bulging side portion 115 (FIG. b)) is formed. The bulging side portion 115 is indirectly provided with a position for attaching the branch device 20, and a reference portion 50 is formed as a reference when the branch device 20 is moved along the track indicated by the track portion 60. Yes.

  The reference portion 50 is formed, for example, by being painted so that a region having substantially the same width as the raceway groove 63 is conspicuous in the vertical direction of the bulging side portion 115 (substantially the same as the raceway groove 63). The shape is painted, but not limited to this, and may be intermittent or partial.) The color of the reference portion 50 is not particularly limited as long as it is conspicuous but has high contrast to surrounding colors, and may be a pattern, a character, a figure, or the like. The method is not limited to painting, and is appropriate such as processing and pasting of members.

  Next, the construction procedure for attaching the branching device 20 to the bus duct 10 and the movement at that time will be described with reference to FIG.

  First, as shown in FIG. 5A, the operator opens the opening / closing door 40 of the connection unit 12 to expose the plug-in hole 31. Thereafter, the operator moves and arranges the branching device 20 in the vicinity of the connection unit 12, and then brings the branching device 20 closer to the bus duct 10 while maintaining substantially parallelism. At this time, as shown in FIG. 5B, in the side view of the bus duct 10, the position of the branch device 20 is adjusted so that the reference portion 50 can be seen between the track grooves 63 on the branch device 20 side. The branch device 20 is moved closer to the bus duct 10 (moved toward the bus duct 10) while maintaining the state where the reference portion 50 is visible during the period, that is, while maintaining the state where the reference portion 50 is not hidden by the track portion 60.

Next, from the state shown in FIG. 5B, the operator further brings the branching device 20 closer to the bus duct 10 while maintaining the state where the reference portion 50 is not hidden by the track portion 60 (in the illustrated example, vertically downward). 5 (c), the branch terminal 23 is inserted into the plug-in hole 31, and in this state, the one-fix fixing is performed by the first fixing member 24.
The box 22 of the branching device 20 is connected to the bus duct 10 by holding the base 32 of the connection upper and lower plates 30 with the second fixing member 25 and holding the first reinforcing portion 113 a of the bus duct 10 with the third fixing member 26. Fixed to.

  As described above, when the branching device 20 is fixedly attached to the bus duct 10, the branching terminal 23 of the branching device 20 is connected to the inside of the housing of the bus duct 10 via the plug-in hole 31 of the connection upper and lower plates 30. Inserted and inserted between the in-phase conductive connecting members 121 and 121 of the connecting unit 12 of the bus duct 10, the branching terminal 23 and the conductor 111 of the bus duct 10 are electrically connected (not shown). . In addition, the branch apparatus 20 once attached can be removed by performing the reverse procedure of the procedure described above.

  On the other hand, as shown in FIG. 5 (d), the operator, in the step of attaching the branch device 20 to the bus duct 10, the track when the branch device 20 is attached to the bus duct 10 is indicated by the track groove 63 of the track portion 60. When it is likely to come off, the reference portion 50 is hidden by the track portion 60 in the side view and becomes difficult to see. Thereby, the operator can recognize that the branching apparatus 20 cannot be moved appropriately. That is, the operator can determine whether or not the attaching operation of the branching device 20 can be appropriately executed according to how the reference unit 50 is seen.

  Thus, according to the first embodiment, in the step of attaching the branch device 20 to the bus duct 10, the track at the time of mounting the branch device 20 to the bus duct 10 deviates from the track indicated by the track groove 63 of the track portion 60. When or when it is likely to be detached, the reference portion 50 is hidden by the track portion 60 in the side view, or becomes invisible. Therefore, the operator can determine whether or not the branching device 20 can be appropriately moved according to how the reference unit 50 is seen. As a result, the reference unit 50 and the track unit 60 appropriately move the branching device 20. Therefore, it functions as an auxiliary mechanism (for safely inserting the branching terminal 23 into the plug-in hole 31). The track portion 60 and the reference portion 50 may be installed not only on the side wall 22b side of the branching device 20, but also on the front wall 22c side or the rear wall 22d side, or a combination thereof.

<< Modification of First Embodiment >>
In the first embodiment, it is possible to determine whether or not the branching device 20 can be appropriately moved by allowing the operator to visually recognize the reference portion 50 through the raceway groove 63 of the raceway portion 60. It is not limited. You may comprise like the modification shown below.

Specifically, the raceway groove 63 is not formed in the raceway piece 62 of the raceway portion 60, but the shape of the raceway piece 62 itself is such that the bus duct 10 when the branch device 20 is attached to the bus duct 10 as shown in FIG. It may be formed in a shape indicating the trajectory of the movement of the branching device 20 with respect to. In this case, two reference portions 50 and 50 are formed on the bulging side portion 115 of the bus duct 10 so as to be separated by the width dimension of the track piece 62 shown in the figure. The reference portions 50 are formed so as to be continuous in the vertical direction and are arranged in parallel to each other.
Then, in a side view of the bus duct 10, the operator determines whether or not the branching device 20 can be appropriately moved depending on whether or not the track piece 62 of the track portion 60 enters between the two reference portions 50 and 50. It may be. In this case, the track piece 62 may be only on one side.

  In addition to the above, the connection upper and lower plates 30 of the bus duct 10 are provided with an opening (not shown) into which the track piece 62 of the track portion 60 shown in FIG. 6 can be inserted, and in the opening (not shown), The track piece 62 shown in FIG. 6 may be inserted. In this case, the function of the reference portion 50 of the first embodiment described above is fulfilled by both the opening (not shown) and the two reference portions 50 and 50. In addition, when providing said opening (not shown), even if it does not provide the two reference | standard parts 50 * 50, said opening (not shown) connects the branch apparatus 30 along the track | orbit which the track | orbit part 60 shows. In order to move, it fulfills the function (the same function as the reference unit 50 of the first embodiment described above).

  In the first embodiment, it is possible to determine whether or not the branching device 20 can be appropriately moved by making the reference portion 50 a conspicuous color tone and allowing the operator to visually recognize it through the raceway groove 63. It is not limited.

For example, as shown in FIG. 7 (a), a rod-like shape made of screws, bolts, or the like in the side direction (in the direction protruding perpendicularly to the side surface) from the side surface (in this case, the bulging side portion 115) of the bus duct 10. The reference portion 150 may be provided in a projecting manner, and the reference portion 150 may be moved in the raceway groove 63. In this case, when the track when the branch device 20 is attached to the bus duct 10 deviates from or is likely to deviate from the track indicated by the track groove 63 of the track portion 60, the reference portion 150 is the groove edge of the track groove 63. There is a high possibility that a load is applied to the movement of the branching device 20 in contact with 63a. This makes it easier for the operator to determine whether or not the branching device 20 can be moved appropriately, and as a result, it helps to move the branching device 20 properly (the branching device 20 is placed at an appropriate position in the bus duct 10). A mounting aid, ie, a safe insertion of the branch terminal 23 into the plug-in hole 31).
It is more effective if the reference unit 150 and the reference unit 50 are used in combination.

  Further, in place of the reference portion 150, as shown in FIG. 7B, the side surface of the bus duct 10 (in this case, the bulging side portion 115) extends in the side direction (a direction perpendicular to the side surface). The reference portion 250 having a shape along the shape of the raceway groove 63 (in this case, a linear shape and a shape narrower than the groove width of the raceway groove 63) may be projected. By doing so, when the branching device 20 is attached to the bus duct 10 because the angle of the branching device 20 with respect to the bus duct 10 is deviated from the track indicated by the track groove 63 of the track part 60, or Even when it is likely to come off, the reference portion 250 comes into contact with the groove edge 63a of the raceway groove 63 and a load is applied to the movement of the branching device 20. This makes it easier for the operator to determine whether or not the branching device 20 can be moved appropriately, and as a result, it helps to move the branching device 20 properly (the branching device 20 is placed at an appropriate position in the bus duct 10). A mounting aid, ie, a safe insertion of the branch terminal 23 into the plug-in hole 31). In this case, the reference portion 250 can be regarded as “the above-described track portion 60 of the first embodiment” and the track portion 60 can be regarded as “the above-described reference portion 50 of the first embodiment”. The effect obtained is the same.

  In addition to such a configuration, the above-described reference portions 150 and 250 are configured to slide after contacting the groove edge 63a of the raceway groove 63. In other words, even if the branching device 20 is likely to be moved in an inappropriate manner, the track portion 60 and the reference portions 150 and 250 are slid (function as a guide) to be corrected to an appropriate motion. be able to.

It is the schematic diagram which showed.

  In the following description, the same or similar components as those in the first embodiment are denoted by the same reference numerals and description thereof is omitted. In the second embodiment, the “track portion 60” in the first embodiment is changed to the “track portion 160”, and the “reference portion 50” in the first embodiment is changed to the “reference portion 150 (a modification of the first embodiment). The same configuration as the example) ”,“ opening / closing door 40 ”of the first embodiment is changed to“ opening / closing door portion 140 ”, and“ branching terminal 23 ”of the first embodiment is changed to“ branching terminal 223 ”. As a result, a “positioning hole 33 (bus duct side positioning portion)” is provided in the upper and lower plates 30 of the bus duct 10, and a “branch side positioning portion 70” and an “opening / closing door storage portion 22 f” are provided in the branch device 20.

  First, the structure different from 1st Embodiment among the bus ducts 10 of 2nd Embodiment is demonstrated.

In the second embodiment, the opening / closing door 40 of the first embodiment is changed to an opening / closing door portion 140.
Specifically, as shown in FIG. 8, the opening / closing door 140 is provided with an opening / closing box 141 (an opening / closing box 141 whose bottom surface is open) protruding above the bus duct 10 and an opening / closing box provided above the opening / closing box 141. The box 141 has a pair of open / close doors 142 that can be opened and closed in a double door manner, and a lock member 80 that locks the opening of the open / close door 142, and has a function as a part of the housing of the bus duct 10. Yes.

The open / close box 141 protrudes so as to cover the periphery of the plug-in hole 31 and is formed, for example, to a height that does not interfere with the internal components of the connection unit 12 when the open / close door 142 is opened inside. Yes.
The open / close door 142 is normally biased in the closing direction by a spring (not shown), so that the plug-in hole 31 is normally closed, but is pressed from above to below with a predetermined force or more. Is configured to open the plug-in hole 31.

  The lock member 80 is disposed below the end portion of the opening / closing door 142 and is locked (locked) so that it does not open even when the door 142 is pressed downward from above. When it is pressed from the side, it slides outward in the lateral direction from the lower side of the end portion of the opening / closing door 142 to release the lock. The area of the lock member 80 exposed upward in plan view is preferably smaller than the area of the open / close door 142 so that an operator or the like does not accidentally press it, but the size and position are appropriate. is there.

  In the second embodiment, the upper and lower plates 30 of the bus duct 10 are provided with “positioning holes 33 (bus duct side positioning portions)”. Specifically, as shown in FIG. 8, the connection upper and lower plates 30 of the second embodiment receive the “positioning pieces 72 and 72 of the branch side positioning portion 70” described later, that is, the connection upper and lower plates in this embodiment. A positioning hole 33 (bus duct side positioning portion) is formed on the front end side of the plate 30.

  Next, the structure different from 1st Embodiment among the branching apparatuses 20 of 2nd Embodiment is demonstrated.

  In the second embodiment, a track portion 160 shown in FIGS. 9 and 10 is provided instead of the track portion 60 of the first embodiment. Specifically, the track portion 160 of the second embodiment is different from the track portion 60 of the first embodiment (bending and extending both ends of the base portion 61 to form a pair of track pieces 62). ) To (c), the base portion 161 is divided into two in advance, and the race piece 162 is formed by bending and extending the respective end edges substantially at a right angle. In the second embodiment, as a matter of course, the track piece 162 may be only on one side.

Only the root part of the track piece 162 is formed long on the front side of the branching device 20. This is intended to improve both the strength of the entire track portion 160 and ensure the visibility of the branch terminal 23 in a side view when the branch device 20 is attached to the bus duct 10. Is appropriate. A track groove 163 is provided in the track piece 162. The track groove 163 is formed in a substantially arc shape from the top to the bottom of the track piece 162 and is open so as to divide the track piece 162 on the lower end side of the track piece 162. Note that the shape of the track groove 163 is the same as that of the first embodiment, in which the branch device 20 moves relative to the bus duct 10 when the branch device 20 is attached to the bus duct 10 (more specifically, the track portion 160 is provided). This is a movement trajectory of the portion that is present, and shows an insertion trajectory of the branching terminal 23 with respect to the plug-in hole 31 (opening / closing door 142) indirectly when used in combination with the reference portion 150. It has a shape (may be formed intermittently rather than continuously, or a shape that shows a single trajectory as a whole by combining a plurality of portions).
As shown in FIG. 9B, the track portion 160 is also displaced in the horizontal direction from the branching terminal 223 in a side view of the branching device 20. Therefore, the track groove 163 indirectly indicates an insertion track of the branch terminal 223 with respect to the plug-in hole 31. However, the present invention is not limited thereto, and the track portion 160 may be installed at a position overlapping the branch terminal 223 in a side view of the branch device 20, and the insertion track may be directly indicated by the track groove 163.

  Moreover, in 2nd Embodiment, the box-shaped box 22 is formed in the shape different from 1st Embodiment. Specifically, as shown in FIG. 9, the bottom surface 22a of the box 22 is formed with a recess 22f having a shape capable of accommodating the open / close box 141 of the bus duct 10, and the branching terminal is formed in the recess 22f. 223 is provided. The branching terminal 223 can be electrically connected to the conductor 111 by being inserted between the in-phase conductive connecting members 121 and 121 of the connecting unit 12 of the bus duct 10 in the same manner as the branching terminal 23 of the first embodiment. It is configured as follows.

  Further, an unlocking member 90 for unlocking the door 142 of the bus duct 10 is formed on the terminal block 223a of the branch terminal 223 (from one end (front end) of the terminal block 223a to the unlocking member 90). Is protruding). The lock release member 90 has a shape (bar shape or plate shape) whose tip is sharpened at an acute angle, for example, so that the lock member 80 provided in the bus duct 10 can be pressed downward from above.

  Further, the branching device 20 of the second embodiment is provided with a branch side positioning portion 70 for positioning the mounting position of the bus duct 10 with respect to the housing so as to protrude forward from the front wall 22c on the front side of the bottom surface 22a of the box body 22. ing.

  As shown in FIG. 11, the branch side positioning portion 70 has a flat plate-like base 71 and positioning pieces 72 and 72 formed by bending and extending both side edges of the side of the base 71 substantially at right angles. . The positioning piece 72 may be only on one side.

  The positioning piece 72 has a locking portion 72a that can be locked to the front edge of the positioning hole 33 (bus duct 10 side positioning portion) formed in the connection upper and lower plates 30 of the bus duct 10 in front of the positioning piece 72. In addition, the positioning piece 72 has a shape in which a rectangle is inclined in a side view (in this case, about 45 °). If the branching device 20 is not inclined at that angle, the positioning piece 72 is formed in the positioning hole 33 of the connection upper and lower plates 30. Although it is formed so that it cannot be inserted or is difficult to insert, its shape and angle are not limited thereto.

  In the bus duct system of the second embodiment configured as described above, when attaching the branching device 20 to the bus duct 10, the operator first places the branching device 20 in the vicinity of the connection unit 12 as shown in FIG. As shown in FIG. 12B, the positioning holes 33 provided in the connection upper and lower plates 30 are brought close to the bus duct 10 in a state where the entire wall is inclined so that the front wall 22c side of the branching device 20 faces downward. The positioning piece 72 of the branching side positioning portion 70 of the branching device 20 is inserted into the positioning device 72, and the locking portion 72 a of the positioning piece 72 is locked to the front edge of the positioning hole 33. By this operation, the branch device 20 is positioned on the bus duct 10.

  Then, with the positioning piece 72 as a fulcrum, when the entire branching device 20 is rotated toward the bus duct 10 (that is, when the branching device 20 is moved appropriately to be attached to the bus duct 10), first, an unlocking member is formed. 90 slides sideways by pressing the lock member 80 from above, and the door 142 is unlocked. Next, as shown in FIG. 12 (c), the opening / closing door 142 is opened downward by pressing the branching terminal 223, and the branching terminal 223 is inserted into the plug-in hole 31 through the opening / closing door 140. The reference portion 150 of the bus duct 10 enters between the grooves of the substantially arc-shaped track groove 163 of the track portion 160. At this time, the reference portion 150 does not abut against the track groove 163 or does not hinder the movement of the branching device 20 by sliding even if it comes into contact with the raceway 163. Therefore, the operator moves the branch device 20 along the track groove 163. It can be easily determined that it is moving properly.

Then, when the operator further brings the branch device 20 closer to the bus duct 10 side from the state shown in FIG. 12C, as shown in FIG. 12D, the recess 22f of the branch device 20 (see FIG. 9B). ) And the branching terminal 223 is inserted into the plug-in hole 31, and in this state, is fixed by one touch by the first fixing member 24 (not shown). The branching device 20 grips the first reinforcing portion 113a of the bus duct 10 with the third fixing member 26 (not shown), so that the locking portion 72a, the first fixing member 24, and the third fixing member 26 are three. It is fixed to the bus duct 10 at a place. In the second embodiment, the second fixing member 25 is not provided because it interferes when the branch device 20 is attached to the bus duct 10, but a fixing member having a shape that does not interfere when attaching is provided in advance or retrofitted. You may make it fix the branch apparatus 20 more firmly by installing the 2nd fixing member 25 and another fixing member.
The opening and closing of the opening / closing door 142 is not limited to the branch terminal 223, and a dedicated opening portion may be provided, and the opening / closing door 142 may be pressed and opened by the opening portion. It is only necessary to open 142 by using any component on the branching device 20 side.

On the other hand, for example, when the positioning piece 72 and the positioning hole 33 are not properly aligned and the branching device 20 cannot be moved appropriately with respect to the bus duct 10, as shown in FIGS. 13A and 13B, the bus duct 10. The branching device 20 cannot be attached to.
In this case, the reference portion 150 is locked to the lower end of the track piece 162 as shown in FIG. 13A, or the groove edge 163a inside the track groove 163 as shown in FIG. 13B. The reference portion 150 comes into strong contact, and the branching device 20 can no longer move toward the bus duct 10 side. Therefore, the operator can easily determine that the branching device 20 is not properly moved along the track groove 163. At this time, when the branching device 20 side members such as the branching terminal 223 and the unlocking member 90 are designed not to interfere with the housing of the bus duct 10, the branching device 20 cannot be moved appropriately. In addition, it is possible to prevent as much as possible the components on the branching device 20 side such as the branching terminal 223 and the unlocking member 90 from coming into contact with the housing of the bus duct 10, and as a result, the branching terminal 223, the unlocking member 90, the opening / closing door part 140, etc. The risk of damaging the constituent members can be reduced.

  Thus, according to the second embodiment, in the step of attaching the branch device 20 to the bus duct 10, the orbit when attaching the branch device 20 to the bus duct 10 deviates from the orbit indicated by the track portion 160, or comes off. When this happens, the reference portion 150 is locked to the track portion 160, the reference portion 150 abuts the track portion 160, making it difficult to move the branching device 20, or moving to the bus duct 10 side. Thus, the operator can easily determine whether or not the branching device 20 can be moved appropriately, and as a result, the reference unit 150 and the track unit 160 can use the auxiliary mechanism (bus duct) for appropriately moving the branching device 20. 10 to help attach the branching device 20 to the appropriate position, that is, to safely insert the branching terminal 23 into the plug-in hole 31. A function as an auxiliary mechanism) for.

  For example, when the branching device 20 is moved slightly off the track indicated by the track groove 163 due to a slight shift of the insertion of the positioning piece 72 into the positioning hole 33, the track groove By sliding after the reference portion 150 comes into contact with the groove edge 163a inside 163, it may function as a so-called guide. By doing so, the movement of the branching device 20 is corrected to an appropriate state together with the position of the branching device 20, and the usability is good.

<< Modification of Second Embodiment >>
Further, in the second embodiment, the trajectory clearly indicated by the track portion 160 does not necessarily have to be the track groove 163, for example, a track edge 165 of the track piece 162 as shown in FIG. Even in this case, the same effect as described above can be obtained.

  Moreover, in 2nd Embodiment, as shown to FIG.14 (b) and (c), you may make it form the latching | locking part 166 in the groove edge 163a inside the track groove 163. FIG. By doing so, the reference portion 150 is locked to the locking portion 166 when the track when the branching device 20 is attached to the bus duct 10 deviates from the track indicated by the track portion 160 or when it is likely to come off. Therefore, the movement of the branching device 20 can be stopped, which is convenient.

  Further, as shown in FIG. 15A, the reference portion 150 of the second embodiment is changed to a reference portion 350 of a noticeable color tone having a substantially arc shape like the reference portion 50 of the first embodiment, and is passed through the raceway groove 163. It may be possible to determine whether or not the branching device 20 can be appropriately moved by making the worker visually recognize. By doing so, an effect similar to that of the first embodiment can be obtained.

  Further, as shown in FIG. 15B, the reference portion 450 may be formed by projecting a plurality of screws and bolts from the side surface of the bus duct 10 along the raceway groove 163. (The reference portion 450 may be formed by projecting a plurality of convex portions). By doing so, an effect similar to that of the reference portion 250 in FIG. 7B can be obtained. In this case as well, the reference portion 450 can be regarded as a track portion, and the track portion 160 can be regarded as a reference portion. In this case, the same effect can be obtained.

  In the second embodiment, in addition to such a configuration, the lock member 80 is provided closer to the positioning hole 33 than the plug-in hole 31 (that is, the lock member 80 is provided on the rotation fulcrum side). Thereby, even if the lock release member 90 of the branch device 20 is formed to be relatively small, the lock release member 90 can be designed to press the lock member 80 before the branch terminal 223 presses the door 142. Can be made more compact. Further, since the force is easily applied by the lever principle, the lock member 80 can be slid with a small force.

<< Third Embodiment >>
Next, the bus duct system of 3rd Embodiment is demonstrated using FIGS.

  Here, FIG. 16 is a figure for demonstrating the connection up-and-down board (track part) of 3rd Embodiment, (a) is a top view, (b) is a side view, (c) is It is a rear view. FIG. 17 is a view for explaining a reference portion provided in the branching device of the third embodiment, where (a) is a plan view, (b) is a side view, and (c) is a rear view. It is. FIG. 18 is a schematic diagram showing the construction procedure of the bus duct system of the third embodiment, wherein (a) is a schematic diagram showing a working state in which a branch device is mounted on the bus duct, and (b) is a bus duct. It is the schematic diagram which showed the state by which the branching device was mounted | worn.

  In the following, the same or similar configurations as those in the first embodiment and the second embodiment are denoted by the same reference numerals, and the description thereof is omitted. In the third embodiment, the “connection upper and lower plates 30” and “track portion 160” of the second embodiment are changed to “connection upper and lower plates 130 having the function of the track portion” and provided on the bus duct 10 side. The “reference unit 150” in the second embodiment is changed to “reference unit 550” and provided on the branching device 20 side.

  As shown in FIGS. 16A to 16C, the connection upper and lower plates 130 of the third embodiment have substantially the same side edges as the connection upper and lower plates 30, in addition to the configuration with the same reference numerals. The reinforcing piece 134 is formed by bending and extending at a right angle, and the track piece 135 is formed by extending a part of the rear end side of the reinforcing piece 134 downward. The track piece 135 is provided with a track groove 136, which is formed in a substantially arc shape from the top to the bottom, and is open so as to divide the track piece 135 on the lower end side of the track piece 135.

  As shown in FIGS. 17A to 17C, the reference portion 550 of the third embodiment is a support in which a flat base portion 551 and both side edges of the base portion 551 are bent and extended substantially at right angles. It has pieces 552 and 552 and a reference convex part 553 made of a screw, a bolt or the like that protrudes inward near the tip of the support piece 552. The support piece 552 and the reference convex portion 553 may be provided on only one side.

  In the bus duct system of the third embodiment configured as described above, when attaching the branching device 20 to the bus duct 10, first, the operator places the front wall 22 c side of the branching device 20 as shown in FIG. The positioning piece 72 of the branching side positioning portion 70 of the branching device 20 is inserted into the positioning hole 33 provided in the connection upper and lower plates 130 in a state where the whole is inclined so as to be downward, The locking portion 72 a is locked to the front side edge of the positioning hole 33. By this operation, the branch device 20 is positioned on the bus duct 10.

  Then, using the positioning piece 72 as a fulcrum, when the entire branching device 20 is rotated toward the bus duct 10 (ie, the branching device 20 is appropriately moved to be attached to the bus duct 10), the connection upper and lower plates 130 The reference portion 550 (reference convex portion 553) of the branching device 20 enters between the grooves of the substantially arc-shaped track groove 136. At this time, the reference convex portion 553 does not abut against the raceway groove 163 or does not hinder the movement of the branching device 20 by sliding even if it comes into contact with the raceway 163. It can be easily judged that it can be moved appropriately along.

  That is, in the bus duct system of the third embodiment, the installation relationship of the track part (connection upper and lower plates 130) and the reference 550 part with respect to the bus duct 10 side and the branching device 20 side is opposite to the case of the bus duct system of the second embodiment. It has become. The effect similar to 2nd Embodiment can be acquired also by such a structure of 3rd Embodiment.

As described above, according to the present embodiment (first to third embodiments and modifications thereof), when the branch device 20 is attached to the bus duct 10, the branch device 20 can be easily moved appropriately. That is, it becomes easy to attach the branch device 20 to the bus duct 10.
The present invention is not limited to the above-described embodiments (first to third embodiments and other embodiments), and various modifications can be made within the scope of the gist thereof.

  For example, in the first to third embodiments and the modifications thereof, the case where the insulation-covered bus duct 10 is used has been described. However, the present invention is not limited to this and may be an air-insulated bus duct.

  In the first to third embodiments and the modifications thereof, the case where one set or two sets of the track portion and the reference portion are provided for the bus duct 10 and the branching device 20 has been described. More than that may be provided.

  In the first to third embodiments and modifications thereof, the case where the plug-in hole is provided in the connection unit 12 related to the bus duct 10 has been described, but the present invention is not limited to this. For example, if it is an insulation coating type bus duct, it may be applied to the case where an expanded portion is formed by expanding a part of the bus duct unit 11 in the thickness direction of the bus duct, and a plug-in hole is formed therein, In addition, if it is an air-insulated bus duct, it may be applied to a case where a plug-in hole is provided at an arbitrary position of the housing, and in any case, it is the same as in the first to third embodiments and the modifications described above. Can have an effect.

Further, in the first to third embodiments and the modifications thereof, the case where the track portion and the reference portion are permanently installed with respect to the bus duct 10 and the branching device 20 has been described, but the present invention is not limited thereto, At least one of the track portion and the reference portion may be detachable so that it can be attached only when necessary. In addition, a portion protruding from the bus duct 10 or the branching device 20 in the track portion and the reference portion may be configured to be foldable or retractable, and may be used only when necessary. The same effects as those of the first to third embodiments and the modifications thereof can be obtained.
Further, in the first to third embodiments and the modified examples thereof, the case where the track portion indirectly indicates the insertion track of the branch terminal (23/223) with respect to the plug-in hole 31 has been described. However, the present invention is not limited thereto, and may be an insertion track of the unlocking member 90 with respect to the locking member 80 or the like. That is, the track portion may indicate a track of a specific component member on the branch device 20 side with respect to a specific component member on the bus duct side when the branch device 20 is attached to the bus duct 10. Controlling the relationship between the constituent members by the track portion and the reference portion leads to appropriately moving the entire branching device 20 with respect to the bus duct 10.

  As mentioned above, although the bus duct system of 1st thru | or 3rd embodiment and its modification was demonstrated, this invention is not limited to this, If it is a range which can implement this invention, each structure of embodiment and other embodiment A configuration in which each configuration of the embodiment or modification is partially extracted, or a part or all of each configuration in the embodiment or modification is arbitrarily extracted and combined. The form is also widely included.

In addition, embodiment of this invention mentioned above can be shown as follows by another expression.
Specifically, a bus duct (bus duct 10) having a housing provided with a plug-in hole (plug-in hole 31), and a branching device (branching device 20) attached to the position of the plug-in hole (plug-in hole 31) A first bus duct side positioning portion (positioning hole 33) for positioning a mounting position of the branch device (branch device 20), and the branch device (branch device 20). ) For positioning the mounting position of the second bus duct (reference portion 150, reference portion 450, track piece 135), and the branching device (branching device 20) has a mounting position with respect to the housing.

It is desirable that the third distance between the second bus duct side positioning portion (the reference portion 150, the reference portion 450, and the track piece 135) is set to be longer. It is possible to achieve better compatibility between easy alignment and accurate alignment.

  Further, the above invention can be further expressed by another expression: a bus duct (bus duct 10) having a housing provided with a plug-in hole (plug-in hole 31), and the plug-in hole (plug-in hole 31). And a branching device (branching terminal) inserted into the plug-in hole (plug-in hole 31) in the branching device (branching device 20). 223), a branch-side positioning part (branch-side positioning part 70) for positioning the mounting position with respect to the housing, and a branch-side protection part (track part 160 / reference part 550) for protecting the constituent members of the bus duct system. Is formed in the housing for positioning of the mounting position of the branching device (branching device 20). When the alignment between the bus duct side positioning portion (positioning hole 33) and the bus duct side positioning portion (positioning hole 33) and the branch side positioning portion (branch side positioning portion 70) is insufficient, the branch side protection is performed. A bus duct side protection portion (reference portion 150, reference portion 450, track piece 135) that abuts on the portion (track portion 160, reference portion 550) is formed.

  This configuration not only facilitates proper movement of the branching device when attaching the branching device to the bus duct, but if the positioning is insufficient, the housing on the bus duct side and the member on the branching device side The possibility of interference can be reduced.

  In this case, at least the branch terminal (in the state where the branch side protection part (track part 160, reference part 550) and the bus duct side protection part (reference part 150, reference part 450, track piece 135) are in contact with each other). It is desirable that the branch terminal 223) is designed so as not to interfere with the housing on the bus duct (bus duct 10) side, so that in the unlikely event that the alignment is insufficient, the housing on the bus duct side The possibility of interference with the branching terminal can be reliably eliminated.
