  In the electricity distribution panel described in Patent Document 1, since the handle of the branch switch protrudes from the cover, the handle may be operated carelessly. In order to avoid such a disadvantage, it is conceivable to arrange the handle in the cover so that the handle does not protrude from the protrusion even if it is exposed at the protrusion. In such a configuration, it is necessary for the user to insert a finger into the protruding hole to operate the handle. However, although the projecting hole is usually formed to a width that allows the handle to move, it may not be formed wide enough to insert a finger to operate the handle. The handle operation becomes difficult.

  On the other hand, in the case of the distribution board described in Patent Document 2, all the branch switches are exposed from the window holes of the cover, so the operability of the handle is not impaired as described above. However, when the cover has a large window hole, when the cover is produced by resin molding, the fluidity of the resin in the mold is not good, and it is difficult to efficiently carry out the resin molding. Specifically, as shown in FIG. 9, since the resin injected from the injection port 101a of the mold 101 wraps around from both sides of the convex portion 101b for forming the window hole as shown by a broken line, the mold It takes time until the resin is injected into the whole of 101.

  An object of the present invention is to realize a distribution board which can efficiently carry out resin molding of a main body cover without impairing the operability of the handle of the branch switch.

A distribution board according to an aspect of the present invention includes a resin main body cover having an opening formed to expose a handle provided for each of a plurality of branch switches, the main body cover comprising: The opening has at least one bridging portion bridged along the moving direction of the handle so as to cross the opening in an area excluding the area where the handle moves, and the extending portion is provided on both sides thereof The plurality of branch switches are provided at positions where they are present.

According to the above configuration, since the plurality of branch switches are disposed in the area divided by the bridging portion of the opening, a sufficiently large space for operating the branch handle is secured. Therefore, the operability of the branch handle is not impaired. Further, according to the above configuration, since the resin also flows to the installation portion at the time of resin molding, it becomes possible to efficiently carry out the resin molding, and the molding time can be shortened.

In the distribution board, a plurality of the installation parts may be provided. Thereby, the strength at the opening of the main body cover can be improved.

  In the distribution board, adjacent ones of the installation parts may be disposed between a predetermined number of the branch switches. As a result, since a predetermined number of branch switches are arranged in each area formed by dividing the opening by the plurality of erected portions, all the branch switches are divided into groups of each area. Therefore, branch switches can be easily counted by multiplying the number of branch switches in the group by the number of groups.

  In the distribution board, the bridging portion may be formed such that the outer surface of the bridging portion is higher than the highest position of the operating range of the handle of the branching switch. Thereby, when arranging the cover for protecting the handle of a branch switch on the construction part, the said cover does not contact with a handle. In addition, even if the cover is pressed, it does not sink by being supported by the erected portion, and therefore does not contact the handle. Therefore, erroneous operation of the steering wheel can be avoided.

  According to one aspect of the present invention, it is possible to efficiently perform resin molding of the main body cover without impairing the operability of the handle of the branch switch.

The top view of the electricity distribution panel concerning one embodiment of the present invention is shown. (A) shows a plan view of the distribution board with the main handle cover and the bifurcated handle cover removed, and (b) shows a perspective view of the distribution board in that state. The top view of the said branch handle cover is shown. It is sectional drawing of the said electricity distribution panel which passes along a branch switch.

It is a top view which expands and shows the location of the 2nd opening window of the electricity distribution panel in the state which attached the branch handle cover (closed). FIG. 7 is a cross-sectional view taken along the line A-A in FIG. 6 schematically showing the bifurcated handle cover and the recess. It is a figure which shows the state in which resin flows in the metal mold | die for resin-molding the main body cover of the said electricity distribution panel.

(Schematic configuration of distribution board)
FIG. 1 shows a plan view of a distribution board 1 according to an embodiment of the present invention. FIG. 2A shows a plan view of the distribution board 1 with the main handle cover and the bifurcated handle cover removed, and FIG. 2B shows a perspective view of the distribution board in that state.

  The distribution board 1 includes a base 2, a body cover 3, a main switch 4, a plurality of branch switches 5, a main handle cover 11, and a branch handle cover 12 (handle cover). The main switch 4 is provided with a main handle 4a for performing switching operation of opening and closing (conduction / shutoff). The branch switch 5 includes a branch handle 5a (handle) for performing switching operation of opening and closing. The main switch 4 and the plurality of branch switches 5 are attached to the base 2. The main body cover 3 is attached to the base 2 so as to cover a wire (bus or the like) provided inside the distribution board 1. The main body cover 3 has a first opening window 3a at a position corresponding to the main handle 4a, and has a second opening window 3b (opening) at a position corresponding to the plural branch handles 5a. The second opening window 3b is provided with a plurality of bridging portions 16 at a predetermined interval. Here, although the base 2, the main body cover 3, the main handle cover 11, and the branch handle cover 12 are made of resin, the present invention is not limited to this, and metal may be used except for the main body cover 3.

  Further, two handle portions 6 are provided on the main body cover 3. The handle portion 6 is a member for fixing the main body cover 3 to the base 2, and is a member for removing the main body cover 3 from the base 2. In addition, the space of the recessed part for arrange | positioning each handle part 6 is provided in each of two mutually opposing side surfaces in the main body cover 3. As shown in FIG. The handle 6 is disposed to be movable in the space of the recess. Thus, the removal operation of the main body cover 3 is facilitated by providing the handle portion 6 in the space of the recess. Thereby, the maintenance work of the panel board 1 is facilitated.

  The main handle cover 11 is attached to the main body cover 3 so as to cover the first opening window 3a. Corresponding convex parts and concave parts are provided around the main handle cover 11 and the first opening window 3 a of the main body cover 3. The main handle cover 11 is fixed to the main body cover 3 by the engagement of the projection and the recess. The main handle cover 11 can be attached and detached (opened and closed) by the user's hand from the outside without using a tool.

  The main handle cover 11 may not be removable but may be configured to rotate about a fixed shaft. However, compared to the pivoting type, the detachable main handle cover 11 does not break the shaft etc. and there is no need for a space where the main handle cover 11 pivots to the front side, so the distribution board can be small in space 1 can be used (installed).

(Branch handle cover)
FIG. 3 shows a plan view of the bifurcated handle cover 12. The branch handle cover 12 is a plate-like member and has a rectangular outer shape. The branch handle cover 12 is made of resin and has a thin plate shape, so it can be elastically deformed. The bifurcated handle cover 12 has a plurality of (here, four) cutouts 12a. Here, the notch 12a has an arc shape, but may have a triangle shape, a square shape, or any shape. The plurality of notches 12 a may be formed in the bifurcated handle cover 12 so as to be symmetrical with respect to at least one central axis of the bifurcated handle cover 12. For example, in the case where the plurality of notches 12a are formed symmetrically with respect to the longitudinal central axis, the branch handle cover 12 is rotated 180 ° with respect to the longitudinal central axis as in the original state. The bifurcated handle cover 12 can be attached to the body cover 3. The same applies to the case of symmetry about the horizontal central axis and the case of symmetry about the center. The bifurcated handle cover 12 is preferably at least partially transparent or translucent. Thus, even when the bifurcated handle cover 12 is closed (attached), the user can view the state of the bifurcated handle 5a through the bifurcated handle cover 12 from the outside.

  FIG. 4 is a cross-sectional view of the distribution board 1 through the branch switch 5. FIG. 4 shows how the branch handle 5a moves from (a) to (c). The bifurcated handle cover 12 is arranged such that the bifurcated handle 5a does not interfere with the moving trajectory. That is, the bifurcated handle cover 12 is disposed outside the operating range of the bifurcated handle 5a, more specifically, at a position higher than the highest position of the operating range of the bifurcated handle 5a. Each branch switch 5 is connected to two of the three types of bus bars 17 for supplying power to the distribution board 1.

  FIG. 5 is a plan view showing an enlarged part of the second opening window 3b of the distribution board 1 in a state in which the branch handle cover 12 is removed (opened). The body cover 3 has a cover support surface 13 (support surface) for supporting the bifurcated handle cover 12 along the periphery of the second opening window 3b. The cover support surface 13 is provided on the substantially entire edge of the second opening window 3 b in order to support the edge of the bifurcated handle cover 12. The main body cover 3 has a plurality of claws 14 which are projections projecting from the main body cover 3. The bifurcated handle cover 12 is held by being sandwiched between the cover support surface 13 and the claws 14. The cover support surface 13 may not be formed where the claws 14 are formed. With such a configuration, it becomes easy to pull out of the mold at the time of resin molding of the main body cover 3. The claws 14 may be protrusions (protrusions) extending along the cover support surface 13 so as to form a groove with the cover support surface 13.

  The cover support surface 13 is provided with a plurality of recesses 15. The cover support surface 13 has recesses 15 at opposing positions of two opposing sides (long sides) of the second opening window 3b. The recess 15 is disposed at a position adjacent to the short side of the second opening window 3 b or in the vicinity of the short side. In the present embodiment, the recess 15 is disposed adjacent to the cover support surface 13 provided along the short side of the second opening 3b. Further, a claw 14 a is provided on the short side of the second opening 3 b on the side where the recess 15 is disposed. The claws 14, 14 a hold the branch handle cover 12 and fix it.

  The second opening window 3 b may be separated by a plurality of bridging portions 16 provided in the main body cover 3. Here, the plurality of erected portions 16 are stretched across the second opening 3b. The upper surfaces (outer surfaces) of the plurality of bridging portions 16 are aligned with the same surface as the cover support surface 13 and, as shown in (a) to (c) of FIG. It is in a higher position. The lower surfaces of the plurality of bridging portions 16 are disposed in the gaps between the adjacent branch handles 5a. The plurality of bridging portions 16 support the bifurcated handle cover 12 together with the cover support surface 13. The installation section 16 does not overlap the branch handle 5a when viewed in plan (when viewed from the front of the distribution board 1), for each of the plurality of branch switches 5, between the adjacent branch switches 5 Be placed. The installation part 16 is provided in the position where several branch switches 5 exist in the both sides. Moreover, the adjacent installation parts 16 are arrange | positioned in a predetermined number (here three) branch switch 5 between.

  FIG. 6 is an enlarged plan view showing a portion of the second opening window 3b of the distribution board 1 in a state where the branch handle cover 12 is attached (closed). When attaching the branch handle cover 12 to the main body cover 3, the plate-like branch handle cover 12 is inserted between the cover support surface 13 and the claws 14, and the branch handle cover 12 is slid. The bifurcated handle cover 12 is held on the cover support surface 13 and the bridging portion 16 in a state of being attached to the main body cover 3.

  FIG. 7 is a cross-sectional view taken along line A-A in FIG. 6, schematically showing the bifurcated handle cover 12 and the recess 15. As shown in FIG. (A) of FIG. 7 shows a state in which the bifurcated handle cover 12 is attached to the main body cover 3, and (b) of FIG. 7 shows a state in which the bifurcated handle cover 12 is pushed in from the outside. Here, the second opening window 3 b is surrounded by a rectangular wall protruding from the cover support surface 13. Here, the bottom surface of the recess 15 is an arc in a side view, but the present invention is not limited to this, the recess 15 may have any shape such as a triangle or a square in a side view (a cross section of the recess seen from the side) It may be shaped. In a state where the bifurcated handle cover 12 is attached to the second opening window 3b, the end of the short side of the bifurcated handle cover 12 is inserted between the cover support surface 13 and the claws 14a.

  When removing the bifurcated handle cover 12 from the main body cover 3, the user presses the position corresponding to the recess 15 of the bifurcated handle cover 12 from outside with a finger or the like. Since the bifurcated handle cover 12 is elastically deformed along the curved surface of the recess 15, a part (end of the short side) of the bifurcated handle cover 12 is lifted from the cover support surface 13. Thus, the short end of the bifurcated handle cover 12 is disengaged from the claw 14a. In this state, the user can hold the raised end of the bifurcated handle cover 12 with a finger or the like, and can withdraw the bifurcated handle cover 12. Further, since the bridging portion 16 supports the bifurcated handle cover 12, it is possible to prevent the pressed bifurcated handle cover 12 from being bent in an unintended direction and coming into contact with the bifurcated handle 5a.

  When attaching the branch handle cover 12 to the main body cover 3, the end (short side) of the branch handle cover 12 is disposed on the cover support surface 13, and the branch handle cover 12 is slid along the cover support surface 13. Then, after the position of the bifurcated handle cover 12 is aligned with the second opening window 3b, the user once presses the position corresponding to the recess 15 of the bifurcated handle cover 12 with a finger or the like and then releases it. As a result, the end (short side) of the bifurcated handle cover 12 is once drawn into the recess 15 and then returns to the original position. As a result, the bifurcated handle cover 12 enters under the claws 14a located on the short side of the second opening window 3b. Even if the bifurcated handle cover 12 does not enter under the claws 14a only by sliding the bifurcated handle cover 12, as described above, providing the recess 15 in the cover support surface 13 makes it possible to branch easily and reliably. The handle cover 12 can be inserted under the claws 14a. The bifurcated handle cover 12 can be attached and detached (opened and closed) by the user's hand from the outside without using a tool.

When the end of the bifurcated handle cover 12 is arranged on the cover support surface 13 for attachment, the notch 12a of the bifurcated handle cover 12 corresponds to the claw 14 of the main body cover 3 (the notch 12a is a claw 14 ), The position of the bifurcated handle cover 12 may be aligned. From this position, the branch handle cover 12 can be easily inserted between the cover support surface 13 and the claws 14 by pressing the branch handle cover 12 against the cover support surface 13 and sliding it. Further, since the notch 12a is curved in an arc shape (curved shape), the branch handle cover 12 can easily get under the claw 14 when it is slid. In the bifurcated handle cover 12, the angle θ between the side provided with the notch 12a and the side (here, an arc) of the notch 12a adjacent to the side is preferably less than 90 ° (see FIG. 3). ). Therefore, it is particularly preferable that the notch 12a has an arc shape or a triangle shape. Thus, when the branch handle cover 12 is slid, the end of the notch 12a is not caught by the claws 14, so that the branch handle cover 12 can be easily inserted between the claws 14 and the cover support surface 13.

  Compared with the pivoting type that pivots and opens around a fixed shaft, the detachable type handle cover 12 does not break the shaft etc., and there is a space where the branch handle cover 12 pivots to the front side. unnecessary. Therefore, the distribution board 1 can be used (installed) in a small space. In addition, since the branch handle cover 12 of the present embodiment is plate-like, it can be manufactured by cutting out a commercially available resin plate. Therefore, the manufacturing cost can be reduced as compared with the rotary type.

  The bifurcated handle cover 12 may not be removable but may be configured to be pivoted open about a fixed shaft. Even if the bifurcated handle cover 12 is pivotable, the bifurcated handle cover 12 is sufficient in size to cover the second opening window 3 b corresponding to the bifurcated handle 5 a of the bifurcated switch 5. Therefore, the space on the front side for opening the branch handle cover 12 may be small.

  In addition, although the electricity distribution panel 1 of this embodiment is applicable also to the electricity distribution panel for houses, it is especially suitable for game machines (for example, a pachinko machine or slot machine). The reason is described below.

  Generally, in a plurality of gaming machines, electrical control is performed for each of a plurality of groups called islands. And a distribution board (control board) for performing the above-mentioned island electrical control is called an island board. When the gaming machine is a pachinko machine, it is standard that the island be installed on the upper part of the table. On the other hand, when the gaming machine is a slot base, it is standard that the island be installed in the lower part of the base. Thus, generally the installation position of the island is often limited. Therefore, the island is installed in a narrow space in which the top, bottom, left, and right are in close contact with the wall. For this reason, when performing maintenance work on the island, the work space for attaching the island cover also becomes very narrow.

  However, according to the distribution board 1 of the present embodiment, as described above, the main handle cover 11 is provided at a position corresponding to the main handle 4a of the main switch 4 and a position corresponding to the branch handle 5a of the branch switch 5 Is provided with a bifurcated handle cover 12. Therefore, the distribution board 1 can be arranged in a narrow space. Further, in the distribution board 1, since the main handle 4a and the branch handle 5a are covered by the main handle cover 11 and the branch handle cover 12 respectively, an object such as a pachinko ball or coin is used as the main handle 4a and the branch handle 5a. It is possible to prevent contact.

  As mentioned above, the electricity distribution panel 1 of this embodiment is a structure suitable especially for the island board for game machines. The configuration of the distribution board 1 of the present embodiment is newly discovered by the inventor of the present application for the purpose of improving the efficiency of maintenance work of the island board for a gaming machine.

(Resin molding of the main body cover)
FIG. 8 is a view showing a state in which resin flows in a mold for resin-molding main body cover 3 of distribution board 1. When producing the main body cover 3 by resin molding, for example, a mold 21 as shown in FIG. 8 is used. The mold 21 is provided with an injection port 21 a for injecting a resin at a substantially central portion of a side wall on one long side of the mold 21. Further, inside the mold 21, a plurality of convex portions 21b are provided. These convex portions 21 b are portions for forming a plurality of divided (here, three) regions in which the branching switch 5 is disposed in the second opening window 3 b. Further, an inter-wall portion 21c for forming the bridging portion 16 is formed between the opposing side walls of the adjacent convex portions 21b. In FIG. 8, for the sake of convenience, the illustration of the portion for forming the first opening window 3 a is omitted.

  In resin molding, the resin injected from the injection port 21a not only wraps around between the convex portion 21b at both ends and the side wall portion on the short side of the mold 21 as shown by a broken line in FIG. It also flows into the inter-wall portion 21c and reaches the side wall portion side opposite to the side wall portion provided with the inlet 21a (opposite to the inlet 21a). As a result, the amount of the resin flowing to the opposite side of the injection port 21a increases compared to the resin molding using the conventional mold 101 shown in FIG. Time can be shortened.

(Effect of distribution board)
As described above, according to the distribution board 1 of the present embodiment, the bridging portion 16 provided in the second opening window 3b for exposing the branching handle 5a is a region where the branching handle 5a moves in the second opening window 3b. A plurality of branch switches 5 are disposed on both sides of the installation portion 16 in the area except for. As a result, since the plurality of branch switches 5 are disposed in the area of the second opening window 3b divided by the bridging portion 16, a space for operating the branch handle 5a is secured sufficiently wide. Therefore, the operability of the branch handle 5a is not impaired. Moreover, the strength of the second opening window 3 b of the main body cover 3 can be improved by providing a plurality of the installation parts 16. Since each installation part 16 is formed in plate shape, the intensity | strength in the 2nd opening window 3b can be raised.

  Moreover, the adjacent installation parts 16 are arrange | positioned in the space between the branch switches 5 of predetermined number (three pieces in this embodiment). As a result, in the distribution board 1, the three branch switches 5 are arranged in each of the four areas formed by the second opening window 3b being divided by the three installation portions 16, so that 12 The branch switch 5 is divided into four groups. Therefore, the branch switch 5 can be easily counted by multiplying the number of branch switches 5 in the group by the number of groups. Of course, the number of branch switches 5 included in one group is not limited to the above three.

  In addition, in a state where the bifurcated handle cover 12 is not provided, even if the bifurcated handle 5a is accidentally turned off during the operation and the bifurcated handle 5a may be turned off, the misaligned within the divided range. The contact can be stopped, and the spread range of the electrical influence can be suppressed within a predetermined range.

  Furthermore, the installation part 16 is formed so that the outer surface of the installation part 16 may be higher than the highest position of the operation range of the bifurcated handle 5a. As a result, even when the bifurcated handle cover 12 is closed, the bifurcated handle cover 12 does not contact the bifurcated handle 5a. Moreover, since the branch handle cover 12 does not sink when being held down by being supported by the bridging portion 16, it does not contact the branch handle 5a. Therefore, the erroneous operation of the branch handle 5a can be avoided.
