The fixing auxiliary member 7 is configured so that the lower surface of the fixing plate 72 and the lower surface of the bottom plate 2a of the box body 2 are substantially parallel to each other with a distance of the support piece 73, and the shape, size, and arrangement of each part are set. Is set. Further, the fixing plate 72 has a pair of long holes 72a and 72a provided at substantially the center in the front-rear direction at the time of attachment at both ends in the width direction, and the long holes 72a have a circuit track shape that is long in the width direction. The fixture 65 can be attached.

  The fixing part constituted by the fixing auxiliary member 7 and the fixing tool 65 is a fixing part different from the one fixing part when the fixing part constituted by the fixing member 6 and the fixing tool 65 is one fixing part. Correspondingly, of the front end side and the rear end side of the box body 2, it is provided on the side opposite to the installation side of the one fixed portion.

[Mounting and branching of bus duct branching device of embodiment to bus duct]
Next, the mounting of the bus duct branching device 1 of the embodiment to the bus duct 10, in other words, the assembly of the bus duct branching structure will be described. FIG. 8A is a side view showing a separated state of the bus duct branching device and the bus duct of the embodiment, FIG. 8B is a plan view of the bus duct, and FIG. 9A is a guide member of the bus duct branching device of the embodiment. FIG. 9B is an enlarged explanatory view, FIG. 10A and FIG. 10B are side explanatory views for explaining fixing by the fixing member of the bus duct branching device of the embodiment, and FIG. FIG. 11B is a partially longitudinal front view for explaining the fixing by the fixing member of FIG. 10.

  First, the bus duct 10 of this example to which the bus duct branching device 1 of the embodiment is attached will be described. As shown in FIGS. 8 to 11, the bus duct 10 is configured to connect the bus duct units 11 and 11 to be connected to each other through a separate connection unit 12. The bus duct unit 11 is provided with insulatively coated flat three-phase conductors 111 arranged in parallel in the thickness direction, and pipe spacers 112 having a substantially rectangular shape in plan view are arranged on both sides of the conductor 111 in the width direction. The conductor 111 and the pipe spacer 112 are collectively sandwiched between side plates 113 and 113 having a substantially U-shaped cross-sectional view, and bolts 114a and nuts 114b inserted through the side plates 113 are fastened and fixed.

  First and second reinforcing portions 113a are bent at substantially right and left ends in the thickness direction of the conductor 111 at the upper and lower end edges of the side plate 113 and extend laterally. A second reinforcing portion 113b is extended substantially inward in the width direction of 111, and the strength of the bus duct unit 11 is increased. As shown in FIG. 8C, a plurality of chevron-shaped knurled grooves 112a are formed on both sides of the pipe spacer 112 in the width direction of the conductor 111, and the surface area is increased by the knurled grooves 112a to enhance the heat radiation effect. ing. Further, the knurled groove 112a is not engraved in the middle of the bus duct unit 11 in the width direction, and an area where the knurled groove 112a is not engraved is used as a reference line indicating the center of the bus duct unit 11 in the width direction. It is done.

  The connection unit 12 is disposed along the outer surface in the thickness direction of the end portion exposed from the insulating coating of the in-phase conductors 111 and 111 disposed opposite to the bus duct units 11 and 11 to be connected, and the in-phase conductors 111 and 111. A conductive connecting member 121 that electrically connects the conductors, and the outermost conductors that are electrically connected by the conductive connecting member 121 and between the different-phase conductors 111 and 111 that are electrically connected by the conductive connecting member 121. 111 and an insulating separator 122 that insulates between the connection side plates 123 arranged outside thereof, and a connection side plate 123 that clamps them from the outside, and these are fastened by a fastening tool 124 so that the bus duct unit 11. 11 are connected to each other.

  Connection plates 115 are provided on both sides in the width direction of the conductor 111 between the connection unit 12 and the connection end portions of the bus duct units 11 and 11 connected to the connection unit 12, and conductive connection members 121 of the connection unit 12, The insulating separator 122, the connection side plate 123, and the side plate 113 of the bus duct unit 11 and the pipe spacer 112 are collectively covered so as to protect the connection portion of the bus duct 10. The connection plate 115 is inserted with a bolt 116a inserted through the first reinforcing portion 113a of the bus duct unit 11, and is fixed to the bus duct unit 11 by tightening a nut 116b. In the bus duct 10, the outer surface of the connection plate 115 becomes a mounted surface (surface on which the bus duct branching device 1 is mounted) in a portion where the connection plate 115 is attached, and a bus duct in a portion where the connection plate 115 is not attached. A surface formed on the outer side of the side plate 113 and the pipe spacer 12 of the unit 11 is a mounted surface.

  In addition, as shown in FIG. 8B, a pair of guide holes 115a and 115a are formed in one connection plate 115 as guide openings at both ends in the width direction of the connection plate 115 and on one side in the longitudinal direction. The guide hole 115 a is disposed on the upper side of the one bus duct unit 11 and is provided at a position slightly outside the one bus duct unit 11. Further, one connection plate 115 is provided with an insertion port 115b serving as an opening when the branching terminal 5 is inserted so that the branching terminal 5 comes into contact with the conductive connection member 121 in the connection unit 12. When not used for branching, the insertion opening 115b is closed and protected by a lid 115c that can be freely opened and closed. For example, if the guide holes 115a are provided at both ends in the width direction of the connection plate 115 and at both sides in the longitudinal direction, the directionality when the bus duct branching device 1 is attached to the bus duct 10 can be eliminated. . Alternatively, the guide holes 115a may be provided alone without being provided in pairs, or a plurality or a plurality of pairs may be provided.

  When branching from the bus duct 10 with the bus duct branching device 1 of the embodiment, the bus duct branching device 1 is arranged in the vicinity of the connection unit 12 as shown in FIG. The arranged bus duct branching device 1 is a state in which the fixing portion composed of the fixing member 6 and the fixing device 65 is rotated up to the front wall 2c side of the box body 2 and is deformed in a direction away from the mounting surface of the bus duct 10. In the closed state, the binding string 68 attached to the fixing member 6 is bound to the handle 2f to maintain the deformed state. The step of changing to the deformed state can be performed at an appropriate time before the bus duct branching device 1 is attached to the bus duct 10.

  Then, as shown in FIG. 9, the box 2 is brought close to the bus duct 10 while the attachment path of the box 2 is regulated by the pair of regulating members 9, 9, and the guide hole 115 a of the connection plate 115 is placed under the fixing member 6. The guide piece 32 of the guide member 3 provided on the side is inserted and introduced, and the protruding locking portion 32a of the guide piece 32 is hooked on the locking edge of the guide hole 115a. By introducing the guide piece 32 into the guide hole 115a, the box 2 is moved so that the mounting surface of the box 2 is arranged on the mounting surface of the bus duct 10 while accurately regulating the position or mounting path of the box 2. 2 is guided to the mounting position.

  When the locking portion 32a is introduced until it is hooked on the locking edge of the guide hole 115a, as shown in FIG. 10 (a), the guide member 3 is used as an axis, and the locking portion 32a and the guide are described in more detail. The box body 2 is rotated with the locking edge of the hole 115a as an axis until the box body 2 is in a state along the bus duct 10, so that the branching terminal 5 is electrically connected to the conductive connection member 121 in the connection unit 12. The mounting members 4 provided on both sides in the width direction of the box body 2 are engaged with the second reinforcing portions 113b of the bus duct unit 11, and the bus duct branching device 1 is simply fixed to the bus duct 10 and attached. It is done. The attachment member 4 constantly urges the hook-like attachment portion 41 inward by an elastic spring, and the attachment portion 41 is brought into contact with the region near the boundary between the first reinforcement portion 113a and the second reinforcement portion 113b. The mounting portion 41 that has moved outward and has overcome the second reinforcing portion 113b is engaged with the second reinforcing portion 113b by the urging force. In this way, the bus duct branching device 1 is in an attached state in which it is physically and electrically attached to the bus duct 10.

  In the guide piece 32 of the guide member 3, when the bus duct branching device 1 is inserted into the guide hole 115 a and attached to the bus duct 10, a color that stands out from the outside by the connection plate 115 is conspicuous. If a tape is applied or a paint is applied, the success or failure of insertion of the guide piece 32 into the guide hole 115a can be determined by the color, and the operation becomes easier.

  Further, the guide opening is not limited to the guide hole 115a of the present embodiment, and guides the guide member 3 to be introduced by inserting, engaging, fitting, hooking, etc. the guide member 3 such as a notch, a recess, a clasp, etc. It is appropriate if possible, and the shape is not particularly limited. Further, since the guide piece 32 is inserted into the guide hole 115 a that is opened at the end of the connection unit 12 in the width direction, it does not affect the energization of the bus duct 10.

  Due to the restricted arrangement, the branch terminal 5 can be inserted into the bus duct 10 without visually confirming the position of the branch terminal 5. In addition, when the mounting surface of the box body 2 is disposed on the surface to which the bus duct 10 is to be mounted or after the mounting, the fixing member 6 or the fixing portion constituted by the fixing member 6 and the fixing tool 65 is attached to the bus duct 10. Since the deformed state is separated from the surface, it is possible to avoid a situation in which the fixing member 6 or the fixture 65 interferes with the bus duct 10 and obstructs the introduction of the guide member 3 or the insertion of the branching terminal 5, and the bus duct branches. The attachment work of the apparatus 1 can be performed easily. In addition, the operator can easily visually recognize the introduction portion of the guide piece 32 into the guide hole 115a, and the attachment work can be easily performed in this respect.

  Incidentally, even when the bus duct branching device 1 is not in a deformed state in advance, the fixing member 6 or the fixing portion constituted by the fixing member 6 and the fixing tool 65 can be rotated by the hinge 61, so that the introduction angle of the box body 2 can be adjusted. Accordingly, the fixing member 6 or the fixing portion is pushed by the mounting surface of the bus duct 10 and is rotated and tilted. Therefore, the mounting operation of the bus duct branching device 1 is easier than the configuration in which the fixing member 6 or the fixing portion does not open and close. . In addition, since the fixing member 6 or the fixing portion can be easily lifted by a hand or the like to be in a deformed state separated from the mounting surface, the operator can visually recognize the introduction portion of the guide piece 32 into the guide hole 115a. In this case, the fixing member 6 or the fixing part can be lifted up and visually recognized. In this respect, the mounting operation of the bus duct branching device 1 is facilitated as compared with the configuration in which the fixing member 6 or the fixing part does not open and close. It should be noted that it is preferable that two guide portions 32 are introduced into the guide hole 115a so that the operator can visually recognize at least one of the two. By introducing the guide piece 32 into the guide hole 115a, it is possible to easily introduce the other on the basis of the introduced side.

  Thereafter, the bus duct branching device 1 removes the binding string 68 with a tool or the like in the attached state attached to the bus duct 10 shown in FIG. 10A, and the fixing member 6 or the fixing member 6 and the fixing tool 65 are used. A step of returning the configured fixing portion from the deformed state is performed. In the returning step, as shown in FIG. 10B, the fixing member 6 or the fixing member composed of the fixing member 6 and the fixing tool 65 is opened and the guide member 3 protruding from the front wall 2c of the box 2 is provided. The base plate 31 is rotated to a position where the lower surface of the fixing plate 63 comes into contact with a part of the upper surface of the base 31. In other words, as shown in FIG. It rotates to the position where the connection plate 115 is disposed, and is in an open state with respect to the box 2.

  In the open state, the bolt 66a and the nut 66b of the fixture 65 are loosened, and the second piece of the bus duct unit 11 is placed on the clamping piece 653 of the fixture 65 as shown in FIGS. 10 (b) and 11 (b). Get over the reinforcing part 113b. Then, the fixing tool 65 is moved in the long hole 63b of the fixing plate 63, and moved to the inner side in the width direction of the fixing plate 63 to a position where the upper end of the support leg 652 and the back surface of the fixing plate 63 abut. The first reinforcing portion 113a and the side plate 113 are clamped by the support piece 64 at the front end of the metal plate and the clamping piece 653 of the fixture 65. Further, the bolt 66a and the nut 66b are fastened, and a part of the upper surface of the base portion 31 of the guide member 3 protruding from the front wall 2c of the box body 2 is pressed to the bus duct 10 side by the fixing plate 63, so that the bus duct branching device 1 Is fixed to the bus duct 10. In other words, the fixing part constituted by the fixing member 6 and the fixing tool 65 fixes the box body 2 to the bus duct 10 such that the protruding portion of the guide member 3 is pressed against the attached surface side of the bus duct 10. In the fixed state, the bus leg branching device 1 is fixed to the bus duct 10 with the support leg 652 serving as a fulcrum, the bolt 66a and the nut 66b serving as a power point, and the holding piece 653 serving as an operating point.

  In the fixed state, the clamping piece 653 is provided obliquely with respect to the base portion 651 in the fixing tool 65, and as shown in FIG. 11B, this is the boundary between the side plate 113 and the first reinforcing portion 113a. The front end of the holding piece 653 can be brought into contact with the inside of the corner portion, and the front end of the holding piece 653 can be brought into contact with both the side plate 113 and the first reinforcing portion 113a. With the above-described configuration, it is possible to avoid a problem such as deformation as compared with a case where the force required for fixing is distributed to the side plate 113 and the first reinforcing portion 113a and the force is applied only to one side.

  In addition, although the fixing tool 65 of this embodiment was made into the substantially U-shaped shape as a whole, another shape may be sufficient, for example, it is good also as a thing without the support leg 652. In that case, if a fixing wall higher than at least the second reinforcing portion 113b of the bus duct unit 11 is provided below the fixing plate 63 in the width direction of the fixing member 6, the fixing tool 65 without the support leg 652 is the same as described above. Can be fixed to. In addition, a rubber member having a circular cross-sectional view may be provided at the tip of the sandwiching piece 653, whereby a tighter fixation can be obtained. Further, it is preferable that the fixing device 65 is fixed by moving the head portion of the bolt 66a toward the inside in the width direction so as to be applied to the second reinforcing portion 113b of the bus duct unit 11 or the end portion of the connection plate 115. As a result, the stability at the time of fixing can be further increased.

  Further, in fixing the fixing auxiliary member 7, the bolt 66 a and the nut 66 b of the fixing tool 65 attached to the fixing auxiliary member 7 are loosened, and as shown in FIG. The second reinforcing portion 113b of the bus duct unit 11 is overcome. Then, the fixing tool 65 is moved in the long hole 72 a of the fixing plate 72, and moved to the inner side in the width direction of the fixing plate 72 to a position where the upper end of the support leg 652 and the back surface of the fixing plate 72 abut. The first reinforcing portion 113a and the side plate 113 are sandwiched between the support piece 73 at the tip of the first piece and the sandwiching piece 653 of the fixture 65. Further, the bolt 66a and the nut 66b are fastened to fix the bus duct branching device 1 to the bus duct 10. In fixing the bus duct branching device 1 to the bus duct 10, it is possible to obtain a necessary strength by fixing the fixing portion composed of the fixing member 6 and the fixing tool 65, but the fixing auxiliary member 7 and the fixing tool are further provided. It becomes possible to fix still more firmly by fixing with another fixing part comprised by these.

  When the bus duct branching device 1 is fixed to the bus duct 10, the width of the fixing member 6 and the fixing auxiliary member 7 including the fixture 65 in the fixed state is equal to or less than the width of the box 2. In other words, the width of the fixing part constituted by the fixing member 6 and the fixing tool 65, and the width of another fixing part constituted by the fixing auxiliary member 7 and the fixing tool 65 are set to be the width. The width is set to be equal to or less than the width of 2, and is provided so as not to protrude to the side of the box 2. With the above configuration, when a plurality of bus ducts 10 are installed in parallel, it is possible to avoid a situation in which the space between adjacent bus ducts 10 and 10 is reduced due to the installation of the bus duct branching device 1. Workability at the time can be improved.

  In the fixed state, as shown in FIG. 10, the fixing plate 63 is separated from the mounting surface of the bus duct 10 by the height of the support piece 64 of the fixing member 6 and is inserted into the first reinforcing portion 113 a of the bus duct unit 11. The bolt 116 a is not pressed by the fixing plate 63. With the above-described configuration, it is possible to prevent the bolt 116a from being blocked by the bolt 116a and preventing the bolt 116a from being damaged by the pressing of the fixing plate 63, so that the bus duct branch device 1 can be securely attached to the bus duct 10. It can be fixed stably. Further, since the fixing plate 72 and the support piece 73 of the auxiliary fixing member 7 are configured in the same manner, the same effect can be obtained. In addition, the structure corresponding to the fixing member 6 of the fixing auxiliary member 7 has the same effect as the fixing member 6. In the fixed state, the bolt 66a and the nut 66b of the fixing tool 65 are provided outside the fixing plates 63 and 72, and the nut 66b is screwed onto the shaft portion of the bolt 66a on the outside. When fixing the tool 65, a situation where a tool or the like is inserted from the side of the bus duct 10 can be avoided, and workability can be greatly improved when a plurality of bus ducts 10 are installed in parallel.

  In the bus duct branching device 1 of the embodiment, the fixing portion constituted by the fixing member 6 and the fixing tool 65 can be separated from the mounting surface of the bus duct 10, and when attached to the bus duct 10, The introduction portion of the guide piece 32 of the guide member 3 is exposed in a direction facing the surface to be mounted, and can be easily and clearly seen by an operator, and is configured by the fixing member 6 and the fixing tool 65 after the mounting. It is securely fixed to the bus duct 10 by the fixing portion. In other words, the bus duct branching device 1 can achieve both workability and reliability in mounting with a simple configuration in which the fixing member 6 or the fixing portion opens and closes. Further, a part of the upper surface of the base 31 of the guide member 3 protruding from the front wall 2c of the box body 2 is pressed and fixed to the bus duct 10 side by the fixing plate 63, so that a lateral shift or the like with respect to the pressing is fixed to the guide member 3. It can be fixed while being regulated by engagement with the guide hole 115a, and can be fixed to the bus duct 10 more reliably.

  Further, when the bus duct branching device 1 is inserted into the bus duct 10 at an angle, the fixing member 6 or the fixing portion is opened and closed (deformed), thereby preventing the fixing member 6 from obstructing the mounting operation. The workability in mounting the bus duct branching device 1 can be further improved. Further, since the fixing member 6 or the fixing portion can be maintained in a state where the fixing member 6 or the fixing portion is lifted in advance (a closed state or a deformed state apart from the mounting surface of the bus duct 10) by the binding string 68, the fixing member 6 or the fixing portion interferes with the bus duct 10. Therefore, it is possible to prevent the attachment work from being obstructed, and the work to lift the fixing member 6 or the fixing portion is not forced.

[Modifications of Bus Duct Branching Device of Embodiment]
In the bus duct branching apparatus 1 of the above embodiment, the fixing member 6 having the hinge 61 is used. However, the fixing member of the present invention is not limited to this, and for example, the fixing member 200 of the first modification shown in FIGS. 12 and 13. Etc. may be used. The fixing member 200 has a substantially Z-shape when viewed from the side as shown in FIG. 12, and is bent from the other end in the short side direction, with a fixing base 201 having a width approximately equal to or less than the width of the box 2. A fixed plate 202 that is extended, and a support piece 203 that is bent and extended at the front end of the fixed plate 202 and that corresponds to a spacing holding portion that protrudes toward the attached surface of the bus duct 10 while being attached to the bus duct 10. Have In the fixing member 200, as shown in FIG. 13, in the open state with respect to the box body 2, the fixed base 201 is arranged along the front wall 2c on the lower end side (bottom plate 2a side) of the front wall 2c of the box body 2. The fixed plate 202 is bent at a substantially right angle from the lower end side of the fixed base 201 and extends forward. The support piece 203 is extended downward on the bus duct 10 side.

  In the open state positioned on the lower side, the fixing member 200 is arranged so that the lower surface of the fixing plate 202 and the lower surface of the bottom plate 2a of the box body 2 are substantially parallel with each other being separated by the support piece 203. The shape, dimensions, and arrangement of the parts are set. In addition, an opening 201 a is provided at substantially the center of the fixed base 201. Further, the fixing plate 202 has an opening 202a provided near the center in the width direction at a position near the tip, and a pair of lengths provided near the center in the front-rear direction at the time of attachment at positions near both ends in the width direction. The long hole 202b has a circuit track shape that is long in the width direction, and the fixture 65 can be attached to the long hole 202b.

  The fixing member 200 is attached to the front wall 2c of the box body 2 through the rail member 210 by inserting the rail member 210 into the opening 201a of the substantially U-shaped rail member 210 attached to the front wall 2c of the box body 2, for example. It is done. In the open state of the fixing member 200, as shown in FIG. 13A, the lower surface of the fixing plate 202 of the fixing member 200 is formed on a part of the upper surface of the base portion 31 of the guide member 3 protruding from the front wall 2 c of the box 2. Abut or approach slightly apart. In the closed state, as shown in FIG. 13B, the fixing member 200 or the entire fixing portion composed of the fixing member 200 and the fixing tool 65 is rotated along the rail member 210. It moves upward (deforms), and the bundling string 68 is passed through the opening 202a and the handle 2f and tied together to hold it in a closed state (the state in which it is deformed).

  In the fixing member 200 of this example or the fixing portion by the fixing member 200, the rail member 210 replaces the hinge 61, and the same effect as the fixing portion by the fixing member 6 can be obtained. Further, while the wing plate of the hinge 61 is attached to the front wall 2c and the other is attached to the fixing member 6, the rail member 210 is attached only to the front wall 2c, and the fixing member 200 is simply provided with an opening 201a. Therefore, it can be manufactured relatively easily. Further, in the configuration of the fixing member 200 and the rail member 210, it is possible to move the fixing member 200 above the bus duct branching device 1 compared to the fixing member 6 by selecting the shape of the rail member 210. Workability can be further improved.

  The rail member 210 may be attached to the front wall 2c at two U-shaped points to ensure high strength, or may be attached to the front wall 2c at one point to reduce manufacturing costs. Further, the rail member 210 is not limited to the U shape, and may be another shape such as a rectangle, or may be a J shape having an open upper end or lower end. In this case, the fixing member 200 is detached from the bus duct branching device 1. It becomes possible. Moreover, the part which does not mention in particular in the 1st modification is the same as that of the structure corresponding to the bus duct branching apparatus 1 of embodiment, and is the same also about the modification mentioned later.

  Further, the fixing member 200 can be further modified. FIGS. 14A to 14D are views showing fixing members of second to fifth modified examples. In the second modification, as shown in the three-sided view of FIG. 14 (a), two arc-shaped rail portions 210b are formed at the lower end of the flat plate-like base portion 210a attached to the front wall 2c of the box 2 in a sectional view. The fixing member 200 is formed with two openings 201a corresponding to the rail portions 210b of the rail member 210, and the two rail portions 210b are inserted into the openings 201a. As a guide, the fixing member 200 or the fixing portion composed of the fixing member 200 and the fixing tool 65 is rotated and deformed. The rail part 210b and the opening 201a may be an appropriate plural number such as appropriate three or four other than two. In the second modification, the fixed member 200 after moving can be held relatively stably by rotating and deforming the fixed member 200 using the plurality of rail portions 210b as guides.

  Further, in the third modified example, as shown in the three views of FIG. 14B, a sectional view is shown at the lower end of the flat base 210 a attached to the front wall 2 c of the box 2 with respect to one fixing member 200. Two rail members 210 each having one arc-shaped rail portion 210b are provided, and two openings 201a corresponding to the rail portions 210b of each rail member 210 are formed in the fixing member 200. Each rail part 210b is inserted, and the fixing part 200 or the fixing part composed of the fixing member 200 and the fixing tool 65 is rotated and deformed with the rail part 210b of each rail member 210 as a guide. The rail member 210 and the opening 201a may be an appropriate plural number such as three or four other than two. Further, the fixing member 200 of the third modified example is provided with a plurality of pairs of long holes 202b such as two pairs, which are shifted in the front-rear direction when the fixing plate 202 is attached. It is possible to increase the fixing force by attaching the fixing device 65, and according to the state of the surface of the first reinforcing portion 113a and the side plate 113 on the fixed side (for example, a state where screws or labels are provided) It is possible to select the mounting position of the fixture 65.

  Further, in the fourth modified example, as shown in a trihedral view of FIG. 14 (c), a relatively large arc-shaped rail portion in a cross-sectional view is provided at the lower end of the flat base portion 210a attached to the front wall 2c of the box body 2. 210b has two rail members 210 formed, the fixing member 200 has two openings 201a corresponding to the rail portions 210b of the rail member 210, and each rail portion 210b is inserted into each opening 201a. Using the two rail portions 210b as a guide, the fixing member 200 or the fixing portion composed of the fixing member 200 and the fixing tool 65 is rotated and deformed. The rail part 210b and the opening 201a may be an appropriate plural number such as appropriate three or four other than two. In the fourth modification, the fixing member 200 can be largely rotated and deformed upward by an amount corresponding to the size of the rail portion 210b, and workability can be further improved. Further, the fixing member 200 of the fourth modified example is cut out at the center on the front end side (supporting piece 203 side) of the fixing plate 202 and both ends on the rear end side (fixing base 201 side) of the fixing plate 202, Before and after the attachment, the operator can easily see the state of the surface to be attached and the portion where the guide member 3 is inserted into the guide hole 115a.

  Further, in the fifth modified example, as shown in a three-sided view of FIG. 14 (d), rails having a substantially rectangular shape in a cross-sectional view are provided at the lower ends of both sides of a horizontally long flat base 210a attached to the front wall 2c of the box 2. It has a rail member 210 in which two portions 210b are formed, a pair of fixing members 200 are provided, an opening 201a corresponding to the rail portion 210b of the rail member 210 is formed in each fixing member 200, and each opening 201a The rail part 210b is inserted, and the two rail parts 210b are used as guides to rotate and deform the fixing member 200 or the fixing part composed of the fixing member 200 and the fixing tool 65. In the fifth modified example, since the pair of fixing members 200 are provided as separate members at both ends of the rail member 210, for example, the mounting surface is not formed at a uniform height due to a step. Secure fixing is possible without being affected. Further, since there is no member that hides the mounting surface between the pair of fixing members 200, the operator visually recognizes the state of the mounting surface and the portion where the guide member 3 is inserted into the guide hole 115a before and after mounting. It is easy to do.

  Moreover, the fixing member of the present invention may be, for example, a fixing member 300 of a sixth modification shown in FIGS. 15 and 16. The fixing member 300 includes a long plate-like fixed base 301 having a width approximately equal to the width of the front wall 2c of the box 2, and a fixed plate 302 that is bent and extended at an acute angle from one end side of the fixed base 301. , A spring member 303 provided substantially at the center of the fixed base 301, and a support piece 304 bent obliquely from the front end of the fixed plate 302. The fixed base 301, the fixed plate 302, and the support piece Reference numeral 304 denotes a substantially Z-shape in cross section. The spring member 303 includes a spring presser 303a formed of a bolt and a nut, and a spring 303b that is held around the bolt screw portion of the spring presser 303a. An opening (not shown) is formed substantially at the center of the fixed base 301, and a spring retainer 303a of the spring member 303 is inserted through the opening. The fixing plate 302 is formed with a pair of long holes 302 a and 302 a provided in the vicinity of the center in the front-rear direction on both ends in the width direction. The long holes 302 a are long in the width direction of the fixing member 300. It has a circuit track shape, and the above-described fixture 65 can be attached.

  The fixed member 300 has its fixed base portion 301 disposed on the lower end side (bottom plate 2a side) of the front wall 2c of the box 2, and one end (one of the spring retainers 303a) located outside the fixed base portion 301 of the spring member 303. The end) is attached to the front wall 2c of the box 2 and attached to the bus duct branching device 1. In the attached state, as shown in FIG. 16A, the spring 303b located between the other end of the spring retainer 303a and the fixed base 301 urges the fixed base 301 toward the front wall 2c, and the spring The fixing member 300 is deformed and arranged so that the fixing base 301 is in close contact with the front wall 2c by the spring force of the member 303, and the state is maintained. That is, the spring member 303 or the spring 303b serves as a holder that holds the deformed state. The fixed plate 302 in the deformed state (closed state) is bent and extended upward at an acute angle from the lower end side of the fixed base 301, and is separated from the surface formed by the bottom plate 2a.

  When the fixing member 300 is pressed with a force exceeding the spring force of the spring member 303, the lower surface of the fixing plate 302 and the lower surface of the bottom plate 2a of the box 2 are slightly separated from each other as shown in FIG. In this state, the lower surface of the fixing plate 302 of the fixing member 300 comes into contact with a part of the upper surface of the base portion 31 of the guide member 3 protruding from the front wall 2c of the box 2 or slightly. It will be in the separated state and will be in an open state. The open fixing member 300 restored from the deformation is fixed to the bus duct 10 by the fixing device 65. In the sixth modification, it is possible to obtain substantially the same effect as that of the fixing member 6 of the above embodiment by using the spring member 303 and pressing the fixing member 65 at the time of fixing.

  Moreover, in the said embodiment, although the fixing member 6 was demonstrated in the bus duct branching apparatus 1 via the hinge 61, it replaced with the hinge 61 and replaced with a sheet-like member, a string member, a bellows member, etc. You may make it attach. When these members are used, the fixing member 6 is prepared separately from the bus duct branching device 1, and after the bus duct branching device 1 is attached to the bus duct 10, the fixing member 6 is connected to the bus duct branching device 1 with these members. It is also possible to fix the bus duct 10 by attaching it. Even in the configuration of these bus duct branch structures, it is possible to obtain substantially the same effect as in the above embodiment.

  In the above embodiment, the fixing member 6 having an opening / closing mechanism is provided on the front wall 2c on the installation end side of the guide member 3 on which the guide member 3 is installed, and the opening / closing mechanism is provided on the rear wall 2d on the opposite side. However, the fixing member having an opening / closing mechanism such as the fixing member 6 or the fixing auxiliary member 7 configured to be opened and closed by the hinge is also provided on the rear wall 2d opposite to the installation end side of the guide member 3. You may make it install. That is, both the one fixing portion provided on the installation side of the guide member 3 and the other fixing portion provided on the opposite side are configured by a fixing member having an opening / closing mechanism.

  Moreover, in the said embodiment, the structure which presses a part of upper surface of the base 31 of the guide member 3 which protrudes from the front wall 2c of the box 2 with the fixing member 6, and fixes the bus duct branching apparatus 1 to the bus duct 10 was demonstrated. However, the location of the guide member 3 pressed by the fixing member 6 is not limited and is appropriate, and the positional relationship between the guide member 3 and the fixing member 6 is not particularly limited. Furthermore, it is good also as a structure which does not press a part of guide member 3 with the fixing member 6, or the structure which fixes the bus duct branching apparatus 1 with the fixing member 6 without pressing a part of guide member 3 and not via the guide member 3. . Also in this case, as in the above embodiment, the bus duct branching device 1 can be separated from the mounting surface of the bus duct 10 by opening and closing the fixing member 6 or the fixing portion. The introduction of the guide member 3 (guide piece 32) to 115a can be easily recognized by the operator, and after the bus duct branching device 1 is attached, the fixing member 6 can securely fix it. Workability and reliability in mounting the bus duct branching device 1 can be achieved with a simple configuration in which the fixing member 6 opens and closes. In the configuration in which the guide member 3 is not interposed in the fixing by the fixing member 6, the guide member 3 may not be provided.

  Moreover, although the said embodiment demonstrated the structure which the base 31 of the guide member 3 protruded from the front wall 2c of the box 2, the positional relationship of the guide member 3 with respect to the box 2 is not limited, and is appropriate. The base 31 may not protrude from the front wall 2c. Even in such a case, since the fixing member 6 and the fixture 65 as the fixing portion are deformed in a direction away from the mounting surface of the bus duct 10, when attaching the bus duct branching device 1 to the bus duct 10, the operator can Since the guide member 3 can be inserted into the guide hole 115a while visually recognizing the guide member 3 and the guide hole 115a from the diagonally upper side or the side, it has excellent workability.

  In the above embodiment, the configuration using the substantially U-shaped fixing device 65 for fixing the fixing member 6 has been described. However, other shape fixing devices may be used, and simple bolt fixing or rivet fixing may be used. It is also possible to use welding fixing or the like, and the configuration for fixing the fixing member 6 to the bus duct 10 is not particularly limited.

  Moreover, although the said embodiment demonstrated the structure attached to the bus duct 10 rotating the bus duct branch apparatus 1, you may make it attach the bus duct branch apparatus 1 perpendicularly | vertically with respect to the bus duct 10. FIG. Further, in this case, if the workability in mounting the bus duct branching device 1 may be sacrificed to some extent, it is possible not to provide a fixing member opening / closing mechanism. By pressing a part of the upper surface of the base portion 31 of the guide member 3 protruding from the wall 2c with the fixing member, it is possible to fix the lateral displacement with respect to the pressing while being regulated by the engagement between the guide member 3 and the guide hole 115a, It can be reliably fixed to the bus duct 10.
