Description

  The present invention relates to a cabinet structure of equipment used by being installed on a wall surface.

  In recent years, due to increasing environmental awareness, there are an increasing number of houses and stores equipped with solar panels for photovoltaic power generation. The electric power generated by the solar panel is adjusted by a power regulator installed on an indoor or outdoor wall surface (hereinafter referred to as “wall surface”) and supplied to an indoor distribution line or a transmission line of an electric power company. . The power regulator is installed by being hooked on an installation plate fixed to the wall surface (see, for example, Patent Documents 1 and 2). For example, the installation plate is installed using a pattern, or is fixed by checking the level using a level or the like in order to obtain the horizontal accuracy of the installed power regulator.

  Stores and the like require a lot of electric power, so multiple power regulators are installed. In general, a plurality of power regulators are arranged in one place on the wall surface due to the installation space and the like, and are usually installed side by side. Each power conditioner includes a terminal portion for connecting a wire connected to the connection box. This wiring is drawn to the wall side from the connection hole provided on the wall, but it can be applied to various restrictions such as where the wiring behind the wall passes and the empty space on the wall, the convenience of construction, and the wall surface of the house. There are cases where only one connection hole for drawing the wiring from the back of the wall can be opened due to reasons such as poor appearance of opening a plurality of connection holes.

  In this way, when a number of wires corresponding to a plurality of power regulators are pulled out and connected to the terminal portions of each power regulator through a connection hole provided in one place on the wall, the power regulator is outside the cabinet. It is inevitable that the wiring is exposed. It is desirable to make the exposed length as short as possible in order to make the exposed wiring cause noise and make it difficult to install the power regulator.

Japanese Utility Model Publication No. 6-084216 JP-A-11-132551

  In view of the above circumstances, the present invention provides a cabinet structure for a wall-mounted device capable of neatly wiring a number of wires corresponding to a plurality of devices installed side-by-side on a wall surface while passing through the inside of the cabinet. The purpose is to do.

  The present invention proposes a cabinet structure suitable for connecting the wiring for each device to the terminal portion of each device by pulling it out collectively from a connection hole provided in one place on the wall. The cabinet structure of the present invention has a first wiring space, a second wiring space, a first knockout portion, and a second knockout portion. The first wiring space is opened in the rear surface of the cabinet, and one end of the first wiring space is arranged to face the connection hole, and is formed in the depth direction in the cabinet. The other end of the first wiring space is continuous with the second wiring space, and is formed over the entire length in the width direction in the cabinet. One end of the second wiring space is continuous with the first knockout portion and is formed on one side of the cabinet. The second knockout portion is formed on the other side of the cabinet, with the other end of the second wiring space continuing.

  According to this cabinet structure, when a plurality of devices are installed side by side on the wall surface, for two adjacent devices, the first knockout portion on one side of the cabinet of one device and the second side of the other side of the cabinet of the other device. The two knockout portions are in a positional relationship facing each other. Alternatively, the second knockout portion on the other side surface of the cabinet of one device and the first knockout portion on one side surface of the cabinet of the other device are in a positional relationship facing each other.

  Therefore, a plurality of wires corresponding to a plurality of devices installed in parallel on the wall surface are drawn out from a connection hole provided at one location on the wall, and the plurality of devices are extracted from the first knockout portion of the cabinet of one device. Are introduced into the cabinet of the one device and passed through the first wiring space in the cabinet of the one device. Then, only the wiring for the one device is connected to the terminal portion of the one device. On the other hand, the wiring for the other device passes through the second wiring space in the cabinet of the one device, and is derived by knocking out the first knockout portion or the second knockout portion of the cabinet of the one device. Furthermore, the second knockout part or the first knockout part of the cabinet of another device is knocked out and introduced into the cabinet of the other device, and the wiring for the other device is connected to the terminal portion of the other device. Connecting.

  In order to effectively use the dead space in the cabinet as the wiring space, it is desirable to form the first wiring space and the second wiring space along the lower surface of the cabinet. In this case, if the first wiring space is formed along one side surface of the cabinet, the wiring can be easily attached.

  The cabinet is formed in a cylindrical shape as an example, and has a bent portion in which a part of the end surface is folded inward in an L shape. Thereby, the first wiring space is formed in the bent portion. A bridge plate may be erected in the cabinet vertical direction. Thereby, the second wiring space is constituted by the bridge plate and the cabinet.

  By adopting a bridge plate shape in which the end of the bridge plate on the side of the second knockout portion is inclined in the depth direction of the cabinet, the bridge plate is arranged in the depth direction of the cabinet. It becomes possible to provide it behind the position where it stands. At this time, since the wiring passed through the second wiring space is gently bent along the inclination of the bridge plate, the stress acting on the bent portion of the wiring can be reduced.

  Further, by forming the cabinet in a cylindrical shape as described above, it is possible to detachably configure one side surface and the lower surface of the first wiring space with a cover. According to this, since the first wiring space is opened by removing the cover during wiring and connection work, workability is improved. In this case, if the first knockout portion is provided in the cover, the first knockout portion can be knocked out with the cover removed, so that the operation is easy.

  In addition, when the first knockout portion is continuously formed from the upper end of the cover, the wiring can be slid from the upper end of the cover and passed through the first knockout portion.

  According to the present invention, a number of wires corresponding to a plurality of devices installed side by side on a wall surface can be pulled out from a connection hole provided at one place on the wall, and can be neatly routed while passing through the inside of the cabinet. . That is, most of the wiring is hidden inside the cabinet, and only a minimum length of wiring is exposed outside the cabinet, so that the installation state of the equipment is not unsightly. Further, since only one connection hole is provided in the wall, the workability of the construction is good.

It is formed over. In the present embodiment, the front wall of the second wiring space 13 is common to the front cabinet 30. Therefore, although the front side of the second wiring space 13 is open in a state where the front cabinet 30 is removed, a wall may be formed on the front side. The first wiring space 12 and the second wiring space 13 are formed in directions orthogonal to each other, and are continuous at the front end of the first wiring space 12.

  A first knockout portion 14 that is continuous from the upper end of the left surface of the cover 50 is formed on the left surface of the cover 50 that covers the left surface of the main cabinet 20 and corresponding to the left wall surface of the second wiring space 13. In the present embodiment, the first knockout portion 14 is formed continuously from a left upper end of the cover 50 to a circular knockout portion formed on the left surface of the cover 50 via a straight line. The first knockout portion 14 is normally closed with a detachable knockout-type lid piece 141 so that the appearance of the main cabinet 20 is not noticeable. The knockout-type lid piece 141 is connected to the cover 50 at two points, for example, and when the first knockout portion 14 is opened, the lid piece 141 is knocked out and separated as shown in FIG. As a result, the first knockout hole 142 is opened in the first knockout portion 14 and a part of the left surface of the first wiring space 13 is opened. The opened first knockout hole 142 is cut out from the upper left end of the cover 50. In the present embodiment, the first knockout portion 14 is provided on the left surface of the cover 50, so that the lid piece 141 can be knocked out and the first knockout hole 142 can be opened.

  On the other hand, a circular second knockout portion 15 is formed on the right surface of the main cabinet 20 and corresponding to the right wall surface of the second wiring space 13. As described above, the second knockout portion 15 is closed by a normally detachable knockout-type lid piece 151 so that the appearance of the main cabinet 20 is not conspicuous. For example, the knockout-type lid piece 151 is connected to the right surface 22 at two points. When the second knockout portion 15 is opened, the lid piece 151 is knocked out as shown in FIG. Thereby, the second knockout hole 152 is opened in the second knockout portion 15, and the right end (the other end) of the second wiring space 13 is opened.

  The power conditioner 10 before being attached to the wall 600 includes a main body 100 in which a heat sink 72, a semiconductor 73, a substrate 70 and the like are incorporated in the main cabinet 20 and covered with a back plate 40, a front cabinet 30, and an installation The board 400 is divided into a cover 50 and a wiring 300.

  In the cabinet structure configured as described above, wiring and connection work when a plurality of power regulators are installed side by side on a wall surface will be described below with reference to FIG. The description will be supplemented partially using FIGS. 1 and 3 to 5. In the present embodiment, as shown in the figure, three power regulators 10A to 10C are installed in such a manner that other power regulators 10B and 10C are arranged on both sides of the central power regulator 10A as a reference. An example will be described. Note that the number of power regulators and the order of arrangement are not limited thereto. 6 shows a state after the power regulator is installed, it is assumed that the front cabinet 30 and the cover 50 (see FIG. 1) are removed during the wiring and connection work.

  Three adjacent power conditioners 10A to 10C are attached at the same height and at the same interval, and the first knockout portion 14A on the left surface 21 of the cabinet of the central power conditioner 10A and the left power conditioner 10B are adjacent to each other. The second knockout portion 15B on the right side 22 of the cabinet faces each other, the second knockout portion 15A on the right side 22 of the cabinet of the central power regulator 10A, and the first side of the left side 21 of the cabinet of the right side power regulator 10C. The 1 knockout portion 14C is in a positional relationship facing each other.

  First, the installation plate 400 on which the central power conditioner 10 </ b> A is installed is installed on the wall 600, and a connection hole 601 is formed at one place on the wall 600 corresponding to the installation plate escape portion 403 of the installation plate 400. The connection hole 601 is a hole for connecting the three wirings 300 </ b> A to 300 </ b> C connected to the terminal boxes 71 of the three power regulators 10 </ b> A to 10 </ b> C and the connection box at the back of the wall 600. In the present embodiment, all the wirings of the three power regulators 10A to 10C are wired to the one connection hole 601 through the cabinet of the central power regulator 10A.

  As shown in FIG. 3, the hooking portion 41 formed on the back plate 40 of the main body portion 100 is locked to the hook portion 401 of the center installation plate 400 to attach the main body portion 100 to the wall 600. At this time, the main body 100 and the installation plate 400 may be fixed with screws or the like, and may be fixed more firmly. The power regulators 10B and 10C adjacent to the left and right are also attached to the wall 600 in the same manner. Then, the wiring 300A is pulled out from the connection hole 601, and the terminal of the wiring 300A is connected to the terminal block 71 through the first wiring space 12A of the central power regulator 10A.

  The right surface of the central power regulator 10A and the cover pieces 141 and 151 of the first and second knockout portions 14A and 15A of the cover 50 are removed (see FIGS. 4 and 5), and the first and second knockout holes 142A and 152A are removed. Open. Similarly, the second knockout portion 15B on the right side of the power adjuster 10B adjacent to the left of the central power adjuster 10A also opens the second knockout hole 152B, and further the cover 50 of the power adjuster 10C adjacent to the right. Similarly, the first knockout portion 14C opens the first knockout hole 142C. At this time, the first knock-out portion 14B of the cover 50 of the power regulator 10B and the second knock-out portion 15C of the power regulator 10B, which are on the outer sides, are attached to both the power regulators 10B and 10C with the cover pieces 141 and 151 being attached. The outside is not exposed. Therefore, it is possible to prevent creatures such as mice and geckos from entering the cabinet.

  The wiring 300B of the power regulator 10B on the left is introduced from the second knockout hole 152B to the power regulator 10B, and is connected to the terminal block 71 of the power regulator 10B from the second wiring space 13B. The wiring 300C of the power regulator 10C on the right is connected to the terminal block 71 of the power regulator 10C through the second wiring space 13C released from the second knockout hole 152A of the central power regulator 10A.

  In this way, the three wires 300A to 300C are pulled out from one connection hole 601 from the connection box at the back of the wall 600, all led from the first wiring space 12A of the central power regulator 10A, and three powers The regulators 10A to 10C are connected to the respective terminal blocks 71.

  After the wiring is completed, the cover 50 of the power regulators 10A to 10C is attached to the main cabinet 20, and finally the front cabinet 30 covers the front, whereby the installation of the power regulator 10 is completed. At this time, since the first knockout portions 14A and 14C of the cover 50 of the power adjusters 10A and 10C are continuously opened from the upper left end of the cover 50, the first knockout portion 14A continuous from the upper end of the cover 50 is used. , 14C can be slid on the straight portion of 14C and passed through the first knockout portion 14A, 14C circular portion. This eliminates the need to work with the cover 50 attached in advance through the first knockout portions 14A and 14C from the tips (terminal portions) of the wirings 300B and 300C. Accordingly, since the cover 50 can be attached after the wiring connection work, the wiring attachment work can be easily and efficiently performed without obstructing the cover 50 during the connection work.

  The first and second knockout portions 14 and 15 can be provided near the center of the main cabinet 20 in the depth direction. At this time, the second knockout portion 15 side of the bridge plate 80 is inclined in the depth direction so that the second knockout hole 152 is positioned in front of the bridge plate 80. By doing so, the wiring 300B and 300C drawn out from the connection hole 601 pass through the first and second knockout portions 14A, 15B, 15A, and 14C, and the wiring 300 that is connected to the terminals of the power regulators 10B and 10C is suddenly changed. The stress applied to the wiring 300 can be reduced without being bent to an angle. Further, the first and second knockout portions 14, 15 can be recessed inside the power regulator 10. Since the step is formed at the peripheral edges of the first and second knockout portions 14 and 15 by being recessed, the step can be knocked out using the step as a guide. Further, a circular rubber lid capable of opening can be attached to the opened first and second knockout portions 14 and 15. By attaching a rubber lid, opening the rubber lid and passing the wiring 300, the rubber lid covers the gap between the opened first and second knockout portions and the wiring 300, and unnecessary creatures such as mice and geckos are unnecessary. Intrusion can be prevented. The first knockout portion 14 formed in the cover 50 is opened with a rubber lid from the front end of the wiring 300 in advance before connecting the terminals, and the upper end of the left surface of the cover 50 with the wiring 300 passing through the rubber lid. The rubber lid can be slid from the straight line portion that is continuous to the circular portion and introduced into the circular portion. Alternatively, by attaching a rubber lid to the opened first knock-out portion 14 in advance and making a notch from the straight portion that remains open (upper portion of the rubber lid), the straight line portion that continues the wiring 300 from the upper end of the cover 50 And can be introduced into a circular portion.

  According to the present embodiment, a number of wires corresponding to a plurality of devices installed side by side on the wall surface can be routed together in a connection hole provided at one place on the wall, and can be neatly routed while passing through the inside of the cabinet. That is, most of the wiring is hidden inside the cabinet and only a minimum length of wiring is exposed outside the cabinet, so it is not unsightly. Further, since only one connection hole is provided in the wall, the workability of the construction is good. The hole that pulls out or pulls the wiring inside the cabinet is a detachable knockout part, and an appropriate opening is provided as necessary, so unnecessary holes do not have to be formed in advance, and there is no need for creatures such as mice and geckos. Intrusion into the cabinet can be prevented if necessary.
