[0013] The following describes an embodiment of the invention. As can be understood from Figs. 1 to 4, the power distribution device mounting member 1 of this embodiment includes a fixing hole 11 into which a fixing screw fs can be inserted, a receiving surface 12 to which force is applied from the fixing screw fs inserted into the fixing hole 11, a leg 13 that abuts against the mounting surface 93, and a protrusion 14 that can abut against the power distribution device 91. This power distribution device mounting member 1 is configured such that the protrusion 14 is provided on one side of the fixing hole 11 and the leg 13 is provided on the other side of the fixing hole 11, and the protrusion 14 can be moved rearward by the force applied from the fixing screw fs to the receiving surface 12 by tightening the fixing screw fs inserted into the fixing hole 11 with the leg 13 abutting against the mounting surface 93. For this reason, it is possible to increase the binding force on the power distribution device 91 by moving the protrusion 14 rearward by the force applied from the fixing screw fs to the receiving surface 12 by tightening the fixing screw fs. This makes it possible to provide a power distribution device mounting member 1 from which the power distribution device 91 is less likely to come off. Furthermore, by tightening the fixing screw fs, it is possible to both attach the power distribution device mounting member 1 to the mounting surface 93 and improve the binding force of the power distribution device 91. The protrusions 14 are provided in two parallel locations. The protrusions 14 provided at the two parallel locations are provided at positions symmetrical with respect to the fixing hole 11, and by tightening the fixing screw fs inserted into the fixing hole 11, the protrusions 14 provided at the two parallel locations can be moved rearward.
[0014] In the following, a switch will be described as an example of the power distribution device 91 attached to the power distribution device mounting member 1, but other types of power distribution device 91 may be used. Specifically, the power distribution device 91 may be a breaker, a terminal block, or the like.
[0015] As can be seen from Figures 1 and 2, the electric power distribution equipment mounting member 1 of the embodiment uses a fixing screw fs when fixing to the mounting surface 93. As can be seen from Figures 1 to 4, this fixing screw fs is not intended to come into direct contact with the electric power distribution equipment 91. However, when mounting the electric power distribution equipment mounting member 1 to the mounting surface 93, a part of the electric power distribution equipment mounting member 1 can be moved by the force applied to the electric power distribution equipment mounting member 1 from the head fsa of the fixing screw fs. The movement of the part of the electric power distribution equipment mounting member 1 moved in this way is used to increase the restraining force on the electric power distribution equipment 91.
[0016] The power distribution device mounting member 1 of the embodiment includes a fixing hole 11 into which a fixing screw fs can be inserted, a receiving surface portion 12 to which force is applied from the fixing screw fs inserted into the fixing hole 11, a back surface portion 15 located rearward of the receiving surface portion 12, legs 13 that come into contact with a mounting surface 93, and a protruding portion 14 that can be inserted into a recessed portion 91a of the power distribution device 91. The power distribution device mounting member 1 of the embodiment is configured such that the protruding portion 14 that can be inserted into the recessed portion 91a provided in the power distribution device 91 can be moved by tightening the fixing screw fs inserted into the fixing hole 11.
[0017] In order to make the protrusion 14 movable, the protrusion 14 is provided on one side of the fixing hole 11, and the leg 13 is provided on the other side of the fixing hole 11. The leg 13 provided on the other side of the fixing hole 11 extends rearward from the back surface 15, where the tip of the leg 13 faces the mounting surface 93. Therefore, a gap Va can be generated between the back surface 15 and the mounting surface 93. When the fixing screw fs inserted into the fixing hole 11 is tightened, it is difficult to push the leg 13 side rearward, but the protrusion 14 side can be pushed rearward because there is a gap Va between the back surface 15 and the mounting surface 93. In other words, the protrusion 14 can be moved rearward by the force applied to the receiving surface 12 from the fixing screw fs inserted into the fixing hole 11. Therefore, it is possible to increase the restraining force on the power distribution device 91.
[0018] 1 and 3, the power distribution device mounting member 1 of the embodiment is configured so that the protrusions 14 are inserted into the recesses 91a provided on both sides of the power distribution device 91. Therefore, a certain degree of restraining force of the power distribution device 91 to the power distribution device mounting member 1 exists even if the protrusions 14 are not moved rearward. However, in order to further increase the restraining force from this state, the protrusions 14 are moved rearward. Therefore, it is possible to prevent the power distribution device 91 from coming off the power distribution device mounting member 1.
[0019] 3 and 4, the length of the protrusion 14 in the front-rear direction is similar to the length of the recess 91a provided in the power distribution device 91 in the front-rear direction, so there is little room for the protrusion 14 to move rearward, but it is still possible for the protrusion 14 to move rearward to some extent. Even in such a situation, the protrusion 14 can move rearward to some extent, thereby increasing the restraining force on the power distribution device 91.
[0020] On the other hand, even if the length of the protrusion 14 in the front-rear direction is not the same as the length of the recess 91a provided in the power distribution device 91 in the front-rear direction, the restraining force on the power distribution device 91 can be increased. For example, as shown in FIG. 5, a gap is formed on the rear side of the protrusion 14. In this state, the power distribution device mounting member 1 restrains the power distribution device 91 to an extent that allows some movement in the front-rear direction. In this state, when the fixing screw fs is tightened, the receiving surface portion 12 is tilted and the protrusion 14 moves rearward (see FIG. 6). In this way, by filling the gap between the power distribution device 91 and the protrusion 14 that was present on the rear side of the protrusion 14, the degree of restraint on the power distribution device 91 can be increased.
[0021] Incidentally, when inserting the protrusion 14 into the recess 91a provided in the power distribution device 91, a part of the power distribution device 91 is inserted into the insertion part 25 provided between the protrusion 14 and the power distribution device facing surface part 21. In order to facilitate this operation, in the embodiment, a through hole part 21a is provided at a position facing the protrusion 14 of the power distribution device facing surface part 21. In this way, the space behind the protrusion 14 can be widened, so that the operation of inserting a part of the power distribution device 91 into the insertion part 25 can be easily performed. It is not necessary that the through hole part 21a is provided in the power distribution device facing surface part 21 penetrating in the front-rear direction. For example, only the front side of the power distribution device facing surface part 21 may be cut out to provide a notch part. In this case, the rear side of the power distribution device facing surface part 21 is not cut out, so that the thickness of a part of the power distribution device facing surface part 21 is thinned. Even in this way, the space behind the protrusion 14 can be widened.
[0022] As will be understood from these descriptions, it is preferable that the power distribution device facing surface portion 21 is configured to have a notch portion or a through hole portion 21 a at a position facing the protrusion portion 14.
[0023] Furthermore, in the case of a power distribution equipment mounting member 1 in which the fixing parts 10 are provided on both sides of the power distribution equipment facing surface 21, it may be difficult to insert the protrusions 14 of the power distribution equipment mounting member 1 into the recesses 91a provided in the power distribution equipment 91. In consideration of this, it is preferable that the power distribution equipment facing surface 21 is configured to be elastically deformable. By providing the fixing parts 10 on both sides of the elastically deformable power distribution equipment facing surface 21, it is possible to reduce the burden of the work of inserting the protrusions 14 into the recesses 91a.
[0024] In addition, in order to facilitate the insertion of the protrusion 14 of the power distribution device mounting member 1 into the recess 91a of the power distribution device 91, it is preferable to make the tip of the protrusion 14 somewhat smaller. However, in order to make it difficult for the power distribution device 91 to move after the protrusion 14 has been inserted into the recess 91a, it is preferable to configure the base end of the protrusion 14 to be larger than the tip. In order to enable such a configuration, it is preferable that the power distribution device mounting member 1 is configured to have a width adjustment portion 14a on at least a part of the side surface of the protrusion 14, the width of which gradually increases from the tip side to the base end side of the protrusion 14. The rear surface side of the protrusion 14 in FIG. 5 is configured to have such a width adjustment portion 14a, and the side surface of the protrusion 14 shown in FIG. 7 has such a width adjustment portion 14a formed in a protruding shape.
[0025] In addition, it is preferable to provide the position restricting portion 17 on both sides of the power distribution device facing surface portion 21, so that the movement range of the power distribution device 91 can be restricted (see FIG. 3). If the power distribution device mounting member 1 is provided with the position restricting portion 17 behind the protrusion 14, the variation in the positional relationship between the protrusion 14 and the power distribution device 91 can be restricted. Therefore, the restriction of the movement of the power distribution device 91 using the protrusion 14 is likely to function appropriately. In the example shown in FIG. 4, the position restricting portion 17 is in contact with the power distribution device 91, but the position restricting portion 17 does not have to be in contact with the power distribution device 91 when the power distribution device 91 is mounted on the power distribution device mounting member 1. It is sufficient that the position restricting portion 17 and the power distribution device 91 are adjacent to each other to an extent that position restriction is possible.
[0026] Incidentally, the power distribution device mounting member 1 does not necessarily have to have two fixing parts 10 each having a receiving surface 12, a fixing hole 11, a protrusion 14, and a leg 13. For example, the power distribution device mounting member 1 may have the fixing part 10 only on one side of the power distribution device facing surface 21. Even in this case, it is preferable that the fixing part 10 is configured to be able to suppress the movement of the power distribution device 91 on the side opposite to the side where the fixing part 10 suppresses the movement of the power distribution device 91 (the other side of the power distribution device facing surface 21). For example, it is preferable to provide a protrusion that can be inserted into a recess 91a provided on the power distribution device 91. This protrusion may or may not be able to move rearward.
[0027] The power distribution device mounting member 1 may not have the power distribution device facing surface portion 21. For example, the power distribution device mounting member 1 may be configured only with the fixing portion 10 having the receiving surface portion 12, the fixing hole 11, the protrusion portion 14, and the leg portion 13. In this case, it may not be possible to attach the power distribution device mounting member 1 and the power distribution device 91 to the mounting surface 93 in a state where they are connected in advance, but the power distribution device mounting member 1 may be attached to the mounting surface 93 at the same time as the power distribution device 91 is fixed to the mounting surface 93. However, in consideration of convenience, it is preferable that the power distribution device mounting member 1 is configured to have the fixing portion 10 and the power distribution device facing surface portion 21. In this way, it is possible to attach the power distribution device mounting member 1 and the power distribution device 91 to the mounting surface 93 in a state where they are connected in advance.
[0028] Furthermore, in the case of a power distribution device mounting member 1 having a fixing portion 10 and a power distribution device-facing surface portion 21, it is preferable to provide an insertion portion 25 into which a power distribution device 91 can be inserted between the protruding portion 14 and the power distribution device-facing surface portion 21. When the protruding portion 14 is moved rearward, it becomes possible to sandwich the power distribution device 91 between the protruding portion 14 and the power distribution device-facing surface portion 21.
[0029] Moreover, it is preferable that the leg 13 provided on the other side of the fixing hole 11 has a configuration in which the tip of the leg 13 extends rearward beyond the power distribution equipment-facing surface 21. Since a gap Vr can be provided between the power distribution equipment-facing surface 21 and the mounting surface 93, the protrusion 14 can be moved rearward with a simple structure. Moreover, with such a configuration, the force applied from the fixing screw fs inserted into the fixing hole 11 to the receiving surface 12 moves the protrusion 14 rearward, thereby making it possible to increase the restraining force applied to the power distribution equipment 91 between the protrusion 14 and the power distribution equipment-facing surface 21.
[0030] As can be understood from these descriptions, it is preferable to have a configuration including a fixing part 10 having a receiving surface part 12, a fixing hole 11, a protrusion 14, and a leg part 13, a power distribution equipment-facing surface part 21 that can abut against the back surface of the power distribution equipment 91, and an insertion part 25 into which the power distribution equipment 91 can be inserted between the protrusion 14 and the power distribution equipment-facing surface part 21. It is also preferable to have a configuration in which the tip of the leg part 13 provided on the other side of the fixing hole 11 extends rearward beyond the power distribution equipment-facing surface part 21.
[0031] Although the present invention has been described above by taking the embodiment as an example, the present invention is not limited to the above embodiment and can be implemented in various forms. For example, the power distribution device mounting member can be used for power distribution devices that do not have a recessed portion. This is because the movement of the power distribution device can be suppressed by making the protrusion provided on the power distribution device mounting member press the pressed portion provided on the power distribution device.
