  The distribution board 1 includes a case 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 case 2.

  The main body cover 3 is attached to the case 2 so as to cover wiring (such as busbars) provided in 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 case 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 6 is a member for fixing the main body cover 3 to the case 2 and a member for removing the main body cover 3 from the case 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).

(Case 2 and body cover 3)
Next, schematic configurations of the case 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 appearance of the case 2 in a state in which the main body cover 3 is removed from the distribution board 1. 3A is a plan view of the case 2, and FIG. 3B is a perspective view of the case 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 case 2. As described above, the case 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, the direction from the lower surface of the case 2 toward the upper surface of the main body cover 3 when the case 2 and the main body cover 3 are attached is referred to as a z direction (height direction) (described later in FIG. 1 and FIG. 2). The lower surface of the case 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 case 2.

  Each of the case 2 and the main body cover 3 has a rectangular cross-sectional shape. Here, the long side direction of the case 2 and the main body cover 3 is referred to as an x direction, and the short side direction is referred to as a 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 30 is provided on each of two opposite side surfaces of the main body cover 3. Each of these cover recesses 30 is a recess space for arranging the handle portion 6. In the present embodiment, the cover recess 30 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 30, respectively. The handle portion 6 is disposed so as to be movable in the cover recess 30. 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 case 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 if at least one of the side surfaces of the main body cover 3 provided with the cover recess 30 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 case 2 is narrow, the user can operate the handle portion 6 with his / her hand, so the main body cover 3 can be easily removed. It becomes. 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 30 is illustrated. However, one handle portion 6 may be provided in only one of the cover recesses 30. That is, the handle portion 6 only needs to be provided in at least one of the cover recesses 30.

  In addition, when providing the handle part 6 only in one of the cover recessed parts 30, it is for fixing the case 2 to the side surface of the main body cover 3 in which the other cover recessed part 30 in which the handle part 6 is not provided is located. Another fixing mechanism may be added. The fixing mechanism may include a claw portion that engages with a part of the case 2, for example. The claw portion has a structure in which the main body cover 3 can be removed from the case 2 by shifting the relative position between the main body cover 3 and the case 2. Thereby, even when the number of the handle portions 6 is one, the main body cover 3 can be stably fixed to the case 2.

  Further, when the number of the handle portions 6 is one, the number of the cover concave portions 30 can be one. That is, the cover recess 30 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 30 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 30 is provided in the two opposing side surfaces of the x direction (long side direction) in the main body cover 3, the fitting (engagement) of the case 2 and the main body cover 3 is more. Stability can be further improved.

  Moreover, according to the said structure, compared with the case where the cover recessed part 30 is provided in the two opposing side surfaces of the x direction in the main body cover 3, the removal operation | work of the main body cover 3 can be made more efficient. However, as shown in a modification example to be described later, the cover recess 30 can be provided on two opposing side surfaces in the x direction of the main body cover 3.

  Subsequently, 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 portion 6 and the cover recess portion 30 are illustrated one by one.

  As shown in FIG. 4, the handle portion 6 includes a fixing portion 64 that fixes the case 2. The fixing portion 64 may be a claw-like member that engages with a part of the case 2. When the handle portion 6 is provided as a handle-like member, the handle portion 6 is preferably rotatable in the cover recess 30.

  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 30 (positive direction of the z-axis in FIG. 2).

  In this case, the fixing portion 64 can be separated from the case 2 as the handle portion 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 30. 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. 4, the rotation center 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 30. ). 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 case 2.

  As described above, by pulling the handle portion 6 to the outside of the cover recess 30 (the z-axis positive direction in FIG. 2 and the direction in which the main body cover 3 is removed from the case 2), the handle portion 6 is pulled. The fixing part 64 can be separated from the case 2 by rotating. For this reason, the main body cover 3 can be removed from the case 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 30 (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 case 2 is not limited to the above. For example, the handle portion 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 30). 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. 4, the work of removing the main body cover 3 can be further facilitated.

  In FIG. 5, the rotation state of the handle part 6 when the handle part 6 is pressed is shown. When the handle portion 6 is pressed in this state, the handle portion 6 rotates about the rotation shafts 65 and 66, and the engagement between the fixing portion 64 and the engaging portion 21 of the fixing portion is released. The main body cover 3 can be removed from the case 2 by pulling the main body cover 3 forward (upward in the figure).

(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. .

  Next, in FIG. 6, a procedure for attaching the handle 6 to the main body cover 3 will be described. FIG. 6 shows a state in which the spring member 7 is fitted to the shaft portions 65 and 66 with respect to the handle portion 6. A double torsion spring is used as the spring member 7.

  First, the both end pieces 71 and 72 of the double torsion spring are pushed in the direction of the handle portion 6 and are inserted in the direction of the handle portion 6 attachment portion of the main body cover 3. When both end pieces 71 and 72 of the double torsion spring reach the portion of the spring receiving wall portion 35 provided on the main body cover 3, the both end pieces 71 and 72 pressed in the direction toward the handle portion 6 are separated and further Insert the handle 6. The spring receiving wall portion 35 is a wall portion standing from the back side of the main body cover 3.

  At this time, the shaft portions 65 and 66 abut against the shaft guide portions 31 and 32 having a concave shape with respect to the traveling direction of the handle portion 6, and are further attracted in the direction of the bearing hole portions 33 and 34. The shaft guide portions 31 and 32 guide the shafts 65 and 66 while being bent, and the shaft portions 65 and 66 reach the bearing hole portions 33 and 34, and the attachment of the handle portion 6 is completed. The shaft guide portions 31 and 32 are wall portions erected from the back surface side of the main body cover 3, similarly to the spring receiving wall portion 35. In addition, a gap portion (d) is provided between the spring receiving wall portion 35 and the shaft guide portions 31 and 32 so that both end pieces 71 and 72 of the spring member can enter.

  After the handle portion 6 is attached, the fitting between the bearing hole portions 33 and 34 and the shaft portions 65 and 66 is held by the elastic force of the shaft guide portions 31 and 32, so that the handle portion 6 can be easily detached. There is no end.

  Both end pieces 71 and 72 of the spring member 7 are located inside a region constituted by the spring receiving wall portion 35 and the shaft guide portions 31 and 32 and are concealed. For this reason, the end pieces 71 and 72 of the spring member do not protrude on the back side of the main body cover 3. Therefore, when the main body cover 3 is attached to the case 2, it does not get caught or damaged by the electric wires arranged inside the distribution board, and keeps the safety of the operator while maintaining the electrical safety. Can do.

In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.
For example, the distribution board is exemplified and described as a cabinet to which the handle structure according to the present invention is applied. However, the present invention is not limited thereto, and the handle structure according to the present invention can be applied to various cabinets.

  For example, the main body cover 3 using the handle structure of the present invention can be applied to a metal cover instead of a general resin.

For example, in the first embodiment, the handle portion 6 can be applied not only to the side surface of the main body cover 3 but also to the surface, top surface, or bottom surface.
