(Schematic configuration of distribution board 1)
First, a schematic configuration of the distribution board 1 according to an embodiment of the present invention will be described with reference to FIGS. 4 and 5. FIG. 4 is a plan view of the distribution board 1. 5A shows a plan view of the distribution board 1 with the main handle cover 11 and the branch handle cover 12 removed, and FIG. 2B shows a perspective view of the distribution board in this state. Show.

  The distribution board 1 includes a base 2 (case), a main body cover 3 (cover), a main switch 4, a plurality of branch switches 5, a main handle cover 11, and a branch handle cover 12. The main switch 4 includes a main handle 4a for performing an opening / closing (conduction / cutoff) switching operation. The branch switch 5 includes a branch handle 5a for performing an opening / closing switching operation. 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 wiring (such as busbars) 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 a second opening window 3b (opening) at a position corresponding to the branch handle 5a. The second opening window 3b is provided with a plurality of erection parts 16 at a predetermined interval. Here, the base 2, the main body cover 3, the main handle cover 11, and the branch handle cover 12 are made of resin, but are not limited thereto, and may be made of metal.

  The main body cover 3 is provided with two handle portions 6. The handle portion 6 is a member for fixing the main body cover 3 to the base 2 and a member for removing the main body cover 3 from the base 2. The handle portion 6 will be described in detail later with reference to FIGS. 1 and 2. As will be described later, the removal of the main body cover 3 is facilitated by providing the handle portion 6. Thereby, the maintenance work of the distribution 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 portions and concave portions are provided around the first opening window 3 a of the main handle cover 11 and the main body cover 3. The main handle cover 11 is fixed to the main body cover 3 by engaging the convex portion and the concave portion. The main handle cover 11 can be attached / detached (opened / closed) by the user's hand from the outside without using a tool.

  Note that the main handle cover 11 is not detachable, and may be configured to rotate around a fixed axis and open. However, the detachable main handle cover 11 does not break the shaft or the like and does not require a space for the main handle cover 11 to rotate forward, compared to the rotary type, so the distribution board can be used in a small space. 1 can be used (installed).

(Base 2 and body cover 3)
Next, schematic configurations of the base 2 and the main body cover 3 will be described with reference to FIG. Although various members other than the terminal block 15 (wiring device) described below are shown in FIG. 3, the members other than the terminal block 15 are not described because they are not related to this embodiment. .

  FIGS. 3A and 3B are views showing the external appearance of the base 2 with the main body cover 3 removed from the distribution board 1. FIG. 3A is a plan view of the base 2, and FIG. 3B is a perspective view of the base 2.

  As shown in FIG. 3, a terminal block 15 for connecting and fixing various wirings inside the distribution board 1 is attached to the base 2. Note that, as described above, the base 2 functions as a case that accommodates the wiring in the distribution board 1 and the terminal block 15. The main body cover 3 functions as a protective member (cover) that protects the wiring and the terminal block 15 so as to cover them.

  3, a direction from the lower surface of the base 2 toward the upper surface of the main body cover 3 when the base 2 and the main body cover 3 are attached is referred to as a z direction (a height direction) (described later in FIG. 1). And see also FIG. The lower surface of the base 2 may be understood as a surface on which the terminal block 15 is provided. Further, the upper surface of the main body cover 3 may be understood as a surface parallel to the lower surface of the base 2.

  Each of the base 2 and the main body cover 3 has a rectangular cross-sectional shape. Here, the long side direction of the base 2 and the main body cover 3 is referred to as the x direction, and the short side direction is referred to as the y direction. In FIG. 3, the x direction, the y direction, and the z direction are directions orthogonal to each other.

  However, for example, the distribution board 1 can be manufactured so that the angle at which the above-described long side direction and the short side direction intersect is other than 90 °. Thus, the x direction, the y direction, and the z direction do not necessarily have to be orthogonal to each other.

(Handle 6)
Next, the configuration of the handle portion 6 will be described in detail with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a schematic configuration of the handle portion 6. FIG. 2 is a cross-sectional view showing a detailed configuration of the handle portion 6.

  First, the handle portion 6 will be schematically described with reference to FIG. A cover recess 31 is provided on each of two opposite side surfaces of the main body cover 3. Each of these cover recesses 31 is a recess space for disposing the handle portion 6. In the present embodiment, the cover recess 31 is provided on two opposing side surfaces of the main body cover 3 in the y direction (short side direction).

  And the handle part 6 is arrange | positioned inside the cover recessed part 31, respectively. The handle 6 is arranged so as to be movable in the cover recess 31. For example, the handle portion 6 may be a handle-like member that can be manually operated by the user. For this reason, the user can remove the main body cover 3 from the base 2 by placing the hand on the handle 6 and moving the handle 6 in a predetermined direction.

  By the way, depending on the installation conditions of the distribution board, it may be required to install the distribution board in a narrow space. For example, a distribution board for a house may need to be installed in a narrow space near the ceiling of a house.

  In such a case, the distribution board is installed in a narrow space where the top, bottom, left, and right are in close contact with the wall. For this reason, when the maintenance work of the distribution board is performed, the work space for removing the cover of the distribution board also becomes very narrow. Therefore, conventionally, it has been difficult to remove the cover of the distribution board arranged in such a narrow space from the case.

  However, according to the distribution board 1 of the present embodiment, even when at least one of the side surfaces of the main body cover 3 provided with the cover recess 31 is in close contact with the wall, the user can A hand can be easily put on the handle portion 6.

Therefore, even when the work space for removing the main body cover 3 from the base 2 is narrow, the user can operate the handle portion 6 with his / her hand, so that the main body cover 3 can be easily removed. It becomes possible. For example, the user can remove the main body cover 3 to the front side of the distribution board 1 (the positive direction of the y axis in FIG. 1).
Thus, according to the distribution board 1 of this embodiment, even if the work space for putting a hand on the side surface of the main body cover 3 is not sufficiently secured, the removal work of the main body cover 3 is conventionally performed. Can be made easier.

  Moreover, according to the distribution board 1 of this embodiment, the work space required in order to remove the cover of a distribution board can be reduced rather than before. For this reason, the freedom degree of installation of the distribution board 1 can be improved rather than before. Thus, according to the distribution board 1 of this embodiment, it becomes possible to cope with the installation conditions in which the size of the installation space is strictly limited.

  In the above-described FIG. 1, the configuration in which each of the two handle portions 6 is provided in the cover recess 31 is illustrated. However, only one handle 6 may be provided in only one of the cover recesses 31. In other words, the handle 6 may be provided in at least one of the cover recesses 31.

  In addition, when providing the handle part 6 only in one of the cover recessed parts 31, in order to fix the base 2 to the side surface of the main body cover 3 in which the other cover recessed part 31 in which the handle part 6 is not provided is located. Another fixing mechanism may be added. For example, the fixing mechanism may include a claw portion that engages with a part of the base 2. The claw portion has a structure in which the main body cover 3 can be removed from the base 2 by shifting the relative positions of the main body cover 3 and the base 2. Thereby, even when the number of the handle portions 6 is one, the main body cover 3 can be stably fixed to the base 2.

  In addition, when the number of the handle portions 6 is one, the number of the cover recesses 31 can be one. That is, the cover recess 31 only needs to be provided on at least one of the two opposing side surfaces of the main body cover 3.

  In addition, as FIG. 1 shows, it is preferable that the cover recessed part 31 is provided in the two opposing side surfaces of the y direction in the main body cover 3. As shown in FIG. According to the said structure, compared with the case where the cover recessed part 31 is provided in the two opposing side surfaces of the x direction (long side direction) in the main body cover 3, the base 2 and the main body cover 3 are fitted (engaged). It is possible to further improve the stability of the.

  Moreover, according to the said structure, the removal operation | work of the main body cover 3 can be made more efficient compared with the case where the cover recessed part 31 is provided in the two opposing side surfaces of the x direction in the main body cover 3. FIG. However, as shown in a modification example to be described later, the cover concave portion 31 can be provided on two opposite side surfaces in the x direction of the main body cover 3.

  Next, a preferred configuration of the handle portion 6 will be described with reference to FIG. Each configuration shown below is a configuration for further facilitating the work of removing the main body cover 3 even when the work space is narrow. In FIG. 2, only one side surface in the y direction of the main body cover 3 is illustrated, so that the handle 6 and the cover recess 31 are illustrated one by one.

  As shown in FIG. 2, the handle portion 6 has a fixing portion 64 that fixes the base 2. The fixing portion 64 may be a claw-like member that engages with a part of the base 2. When the handle portion 6 is provided as a handle-like member, the handle portion 6 is preferably rotatable in the cover recess 31.

  In addition, the handle portion 6 may be provided with a grip portion 63 for the user to grip and operate the handle portion 6. And the handle part 6 may be comprised so that it may rotate by being pulled outside the cover recessed part 31 (positive direction of the z-axis in FIG. 2).

  In this case, the fixing part 64 can be separated from the base 2 as the handle part 6 rotates. For example, consider a case where the user grips the grip portion 63 and performs an operation of pulling the handle portion 6 to the outside of the cover recess 31. In this case, with the user's pulling operation, the gripping portion 63 rotates so as to move in the positive direction of the x axis.

  Here, as shown in FIG. 2, the center of rotation of the handle portion 6 may be understood to be inside the main body cover 3 than the grip portion 63 (the positive direction of the x axis in FIG. 2, inside the cover recess 31). ). Accordingly, when the gripping part 63 rotates so as to move in the positive direction of the x axis, the fixing part 64 rotates so as to move in the negative direction of the x axis. As a result, the fixing portion 64 is separated from the base 2.

  As described above, the handle portion 6 is pulled by pulling the handle portion 6 to the outside of the cover concave portion 31 (the z-axis positive direction in FIG. 2 and the direction in which the main body cover 3 is removed from the base 2). , And the fixing part 64 can be separated from the base 2. For this reason, it becomes possible to remove the main body cover 3 from the base 2.

  According to the said structure, the removal operation | work of the main body cover 3 is made still easier compared with the structure which pushes the handle part 6 inside the cover recessed part 31 (positive direction of the x-axis in FIG. 2) and removes the main body cover 3. Can do.

  In addition, the handle portion 6 is preferably provided with a handle recess 61. The handle recess 61 is a recess space in which a user can place a hand on at least a part of the handle 6. Providing the handle recess 61 makes it easier for the user to place a hand on the handle 6.

  Moreover, it is preferable that the slope 62 which inclines along the z direction (height direction) is provided in the lower part of the handle recessed part 61. FIG. As shown in FIG. 2, the inclined surface 62 is a surface including a position where the z coordinate is minimized among the surfaces of the handle recess 61.

  By providing the inclined surface 62, the opening area of the handle recess 61 increases, so that the user can easily put the hand into the handle recess 61. For this reason, it becomes easier for the user to place a hand on the handle portion 6.

  By the way, operation of the handle part 6 for removing the main body cover 3 from the base 2 is not limited to the above-mentioned thing. For example, the handle 6 may be configured to be able to remove the main body cover 3 by being pushed in the positive direction of the x axis in FIG. 2 (inside the cover recess 31). In such a case, by providing the slope 62, it is possible to make the user particularly easily perform an operation of pushing the handle 6 in the positive direction of the x-axis.

  The dimension of the handle recess 61 in the z direction may be a size that allows the user to insert a finger. For example, if the handle portion 6 is configured to be operable by the user's finger, the user can put the one finger into the handle recess 61 and remove the main body cover 3.

  As described above, according to the preferred configuration of the handle portion 6 shown in FIG. 2, the work of removing the main body cover 3 can be further facilitated.

(Effect of distribution board 1)
As described above, according to the distribution board 1 of the present embodiment, even when the work space for removing the cover from the case is narrow, the work for removing the case can be made easier than before. . The distribution board 1 of the present embodiment can be applied to a residential distribution board, but is particularly suitable for a gaming machine (for example, a pachinko machine or a slot machine). The reason will be described below.

  Generally, a plurality of gaming machines are electrically controlled for each of a plurality of groups called islands. And the distribution board (control board) for performing the electrical control of the above-mentioned island is called an island board.

  For example, when the gaming machine is a pachinko machine, it is standard that the island board is installed on the upper part of the machine. On the other hand, when the gaming machine is a slot base, it is standard that the island board is installed in a lower part of the base.

  Thus, generally, the installation position of the island board is often limited. Therefore, the island board is installed in a narrow space where the top, bottom, left and right are in close contact with the wall. For this reason, conventionally, it has been difficult to remove the island board cover arranged in such a narrow space from the case.

  However, according to the distribution board 1 of the present embodiment, as described above, even when the work space for removing the main body cover 3 from the base 2 is narrow, the work for removing the main body cover 3 is easier than before. Can be For this reason, even in the case of an island board that is required to be installed in a narrow space, the main body cover 3 can be easily removed from the base 2.

  As described above, the distribution board 1 of the present embodiment has a configuration that is particularly suitable for an island board for gaming machines. In addition, the structure of the distribution board 1 of this embodiment was newly discovered by the inventor of the present application for the purpose of improving the efficiency of maintenance work for island boards for gaming machines and improving the degree of freedom of installation. is there.

[Modification]
In the above-described first embodiment, the configuration in which the cover recess 31 is provided on the two opposing side surfaces in the y direction of the main body cover 3 has been exemplified. However, by devising the structure of at least one of the main body cover 3 and the base 2, it is possible to provide cover concave portions on two opposite side surfaces of the main body cover 3 in the x direction.

  For example, in the case where cover concave portions are provided on two opposite side surfaces of the main body cover 3 in the x direction, auxiliary fitting portions may be provided at the corner portions (four corners) of the base 2 and the main body cover 3. . This is because the stability of the engagement between the base 2 and the main body cover 3 can be ensured by providing these auxiliary fitting portions.

  Moreover, when providing a cover recessed part in the two opposing side surfaces of the x direction in the main body cover 3, you may provide a slope (for example, the inclined surface which inclines along the y direction which is a short side direction) in the said cover recessed part. . Hereinafter, in order to explain the advantage of the configuration, a case where the distribution board according to one embodiment of the present invention is applied to an island board for a gaming machine will be considered.

  In the island board for gaming machines, when a relatively long cover recess in the x direction is provided on two opposing side surfaces in the x direction, which is the long side direction of the main body cover 3, a pachinko ball is caught in the cover recess. These pachinko balls may stay in the cover recess. For this reason, there is a concern that the pachinko ball staying in the cover recess may hinder the proper operation of the handle portion arranged in the cover recess.

  However, when the cover recess is provided with a slope inclined along the y direction, even if the pachinko ball is caught in the cover recess, the pachinko ball rolls in the y direction along the slope, Will be discharged. Therefore, the risk of the pachinko balls hindering the operation of the handle portion disposed in the cover recess can be reduced.

  A similar slope may be provided in the cover recess 31 of the first embodiment. For example, a slope inclined along the x direction may be provided in the cover recess 31 in order to reduce a risk that the operation of the handle portion 6 is hindered by the pachinko balls.
