Abstract
Description
[Technical field]
[0001] The present invention relates to an electric device built-in panel. [Background technology]
[0002] Patent Document 1 discloses a residential distribution board in which a protective cover is provided on a mounting base to cover a power supply bar portion that supplies power to a terminal block of a breaker provided on the mounting base. In this residential distribution board, the protective cover is formed of an insulating plate bent into a U-shape, fixing bosses are provided on both sides of the mounting base, and engagement notches into which the fixing bosses are press-fitted are provided at the ends of both legs of the protective cover. The engagement notches are formed in an Ω shape with a press-fit opening provided at one end of a hexagonal hole, and the opening width is slightly smaller than the diagonal width of the engagement portion of the hexagonal cross-section of the fixing boss.
[0003] By aligning the openings of the engagement notches provided on both leg pieces with the engagement portions of the fixing boss and pressing both ends of the central piece of the protective cover, the engagement notches are pressed into engagement with the engagement portions, and the protective cover is attached to the mounting base.

[0004] [Patent Document 1] Public Disclosure No. 61-126712 Summary of the Invention [Problem to be solved by the invention]
[0005] However, in the residential distribution board described in Patent Document 1, the opening width of the engagement notch is slightly smaller than the diagonal width of the engagement portion. Therefore, when attaching the protective cover to the mounting base, it is necessary to press both ends of the central piece to forcibly press-fit the engagement notch into the engagement portion. Furthermore, when removing the protective cover from the mounting base, the press-fit engagement notch gets caught on the engagement portion, making it difficult to release the engagement between the engagement notch and the engagement portion. Therefore, the residential distribution board described in Patent Document 1 has a problem in that it is difficult to attach and remove the protective cover to and from the mounting base.
[0006] Such problems are not limited to the residential distribution board, but occur in general electrical equipment built-in boards that house electrical equipment having conductive terminal portions.
[0007] SUMMARY OF THE PRESENT DISCLOSURE An object of the present invention is to provide an electric equipment built-in panel in which a conductive cover can be easily attached to and detached from an attachment portion. [Means for solving the problem]
[0008] The present invention relates to a housing having a front and a rear; a circuit structure disposed within the housing and including at least one electrical device; a conductive cover disposed in the housing and covering, from a front side, a conductive portion exposed toward a front side of the circuit structure; a mounting portion disposed within the housing and adapted to mount the conductive cover; the conductive cover includes a covering portion that covers the conductive portion and a locking portion that locks onto the mounting portion, The attachment portion includes an insertion / removal portion having an insertion / removal hole through which the locking portion can be inserted and removed, and a locked portion to which the locking portion is locked in a removal direction, The locking portion is an electric equipment built-in panel configured to be movable while inserted into the insertion hole between an insertion / removal position where it can be inserted into and removed from the insertion hole and a locking position where it locks with the locked portion in the removal direction.
[0009] According to the above configuration, the conductive cover can be attached to the mounting portion by moving the engaging portion inserted into the insertion / removal hole from the insertion / removal position to the engaging position, and the conductive cover can be removed from the mounting portion by moving the engaging portion from the engaging position to the insertion / removal position and removing it from the insertion / removal hole.
[0010] In addition, in the present invention, the conductive cover includes a connecting portion that connects the covering portion and the locking portion, the connecting portion is configured to be elastically deformable so that the locking portion moves from the locking position to the insertion / removal position, The locking portion at the insertion / removal position may be biased toward the locking position by elastic deformation of the connecting portion.
[0011] According to the above configuration, the locking portion at the insertion / removal position is biased toward the locking position by the elastic deformation of the connecting portion, so that the locking portion can be easily moved from the insertion / removal position to the locking position.
[0012] In addition, in the present invention, the locking portion includes a neck portion extending in an insertion / removal direction in which the locking portion is inserted into and removed from the insertion / removal portion, and a locking body portion extending from the neck portion in a direction intersecting the insertion / removal direction and the movement direction, The insertion hole of the insertion / removal portion is formed so that the neck portion and the locking main body portion can be inserted and removed in the insertion / removal direction, The engaging portion may be formed with an engaging main body portion that engages with the engaging main body portion in the removal direction, and a neck insertion hole that is adjacent to the engaging main body portion and communicates with the insertion / removal hole, through which the neck portion is inserted.
[0013] According to the above configuration, the conductive cover can be attached to the mounting part by inserting the neck portion and the locking main body portion into the insertion / removal hole, then moving the neck portion to the neck insertion hole and locking the locking main body portion to the locked main body portion, and the conductive cover can be removed from the mounting part by moving the neck portion from the neck insertion hole to the insertion / removal hole and then removing the neck portion and the locking main body portion from the insertion / removal hole.
[0014] In addition, in the present invention, the locking portion is rotatable between a first rotation position and a second rotation position about an insertion / removal direction in which the locking portion is inserted into and removed from the insertion / removal portion, the insertion / removal portion includes a removal prevention portion that is adapted to lock the locking portion at the first pivot position in the removal direction, The insertion / removal hole may be formed so that the locking portion rotated from the first rotation position to the second rotation position can be inserted and removed.
[0015] According to the above configuration, in order to insert or remove the locking portion into or from the insertion / removal hole, the locking portion needs to be rotated from the first rotation position to the second rotation position. Therefore, for example, it is possible to prevent the locking portion inserted into the insertion / removal hole from coming out of the insertion / removal hole due to vibration during transportation. Effect of the Invention
[0016] As described above, according to the present invention, the conductive cover can be attached and detached from the mounting portion by moving the engaging portion inserted into the insertion / removal hole between the insertion / removal position and the engaging position, making it easy to attach and detach the conductive cover from the mounting portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0019] In the following description, the direction corresponding to the left-right direction in Fig. 1 is referred to as the "first direction X", the direction corresponding to the top-bottom direction in Fig. 1 is referred to as the "second direction Y", and the direction in which the front and back of the electrical equipment built-in panel are lined up is referred to as the "front-rear direction Z". In Fig. 1, one side X1 of the first direction X is the right side, and the other side X2 of the first direction X is the left side. Also, in Fig. 1, one side Y1 of the second direction Y is the upper side, and the other side Y2 of the second direction Y is the lower side. Furthermore, one side Z1 of the front-rear direction Z is the front side, which is the front side of the paper in Fig. 1, and the other side Z2 of the front-rear direction Z is the rear side, which is the back side of the paper in Fig. 1.
[0020] In addition to the above-mentioned directions, when describing the configuration of the housing 2, the mounting base 3, and the conductive cover 6, the horizontal direction of each is defined as the "horizontal direction x", the vertical direction of each is defined as the "vertical direction y", and the height direction of each is defined as the "height direction z". The horizontal direction x, the vertical direction y, and the height direction z are mutually perpendicular. In FIG. 1, one side x1 of the horizontal direction x is the right side, the other side x2 of the horizontal direction x is the left side, one side y1 of the vertical direction y is the upper side, and the other side y2 of the vertical direction y is the lower side. Also, one side z1 of the height direction z is the front side of the paper in FIG. 1, and the other side z2 of the height direction z is the back side of the paper in FIG. 1.
[0021] As shown in FIG. 1, the electric device-containing panel 1 includes a housing 2, a mounting base 3, a circuit structure, and a conductive cover 6.
[0022] 1, the housing 2 is a box-shaped member for arranging the mounting base 3, the circuit structure, and the conductive cover 6 inside the housing 2. Therefore, the housing 2 has a front surface and a rear surface that face each other in the height direction z, and a peripheral surface that covers the periphery in the height direction z. The housing 2 includes a storage section 20, an inner lid section 21, and an outer lid section 22. The storage section 20 is for storing the mounting base 3, the circuit structure, and the conductive cover 6. The storage section 20 includes a frame section 200, and a storage main body section 201 located inside the frame section 200.
[0023] As shown in Fig. 1, the frame portion 200 defines the periphery of the housing 2 in the vertical direction y and the horizontal direction x. The frame portion 200 is configured in a circumferential ring shape. In this embodiment, the frame portion 200 is configured in a rectangular shape in which the horizontal direction x is longer than the vertical direction y when viewed from the front. Also, as shown in Figs. 3 and 4, the frame portion 200 extends in the height direction z to ensure the depth of the housing 2 in the height direction z.
[0024] The storage body 201 is used, for example, when mounting the housing 2 on a wall. The storage body 201 is configured in a planar shape extending in the vertical direction y and the horizontal direction x. As shown in FIG. 1, the storage body 201 of this embodiment is rectangular in shape with the horizontal direction x being longer than the vertical direction y. As shown in FIGS. 3 and 4, the storage body 201 is located on the other side z2 of the frame 200 in the height direction z. Therefore, the storage unit 20 is a box-like shape in which the storage body 201 is the rear surface of the housing 2, the frame 200 is the peripheral surface rising from the periphery of the storage body 201 to one side z1 in the height direction z, and the one side z1 in the height direction z facing the storage body 201 is open. The storage body 201 is formed with an insertion hole 20a penetrating in the height direction z. This insertion hole 20a is used when inserting into the housing 2 a first conductor electrically connected to a first power source which is a commercial power source (such as a power generation facility), a second conductor electrically connected to a second power source which is a distributed power source (e.g., a storage battery), or a load conductor electrically connected to a load.
[0025] As shown in Fig. 1, the inner lid portion 21 is intended to cover the mounting base 3, the circuit structure, and the conductive cover 6 from one side Z1 in the front-rear direction Z when the mounting base 3, the circuit structure, and the conductive cover 6 are accommodated in the accommodation portion 20. The inner lid portion 21 is configured in a flat plate shape extending in the horizontal direction x and the vertical direction y. The inner lid portion 21 of this embodiment is rectangular in shape with the horizontal direction x being longer than the vertical direction y. Also, the inner lid portion 21 of this embodiment is formed with a window portion (not numbered) in accordance with the position of the electric device 4 described later.
[0026] As shown in FIG. 1, the outer lid part 22 is for covering the inside of the storage part 20 from one side Z1 in the front-rear direction Z. Therefore, the outer lid part 22 constitutes the front surface of the housing 2. The outer lid part 22 includes an outer lid main body part 220 attached to the storage part 20, and an outer lid door part 221 that covers the outer lid main body part 220. The outer lid main body part 220 has an opening 22a for exposing a part of the inside of the storage part 20. The outer lid door part 221 covers the opening 22a from one side Z1 in the front-rear direction Z. The outer lid door part 221 of this embodiment is attached to one side x1 in the horizontal direction x of the outer lid main body part 220. In addition, the outer lid door part 221 of this embodiment is configured to be switchable between a closed position that covers the opening 22a of the outer lid main body part 220 and an open position that opens the opening 22a by rotating around the one side x1 in the horizontal direction x as a rotation fulcrum in the vertical direction y.
[0027] The mounting base 3 is a plate-like member extending in the vertical direction y and the horizontal direction x. The mounting base 3 in this embodiment is configured in a rectangular shape with the horizontal direction x being longer than the vertical direction y. As shown in Figures 3 and 4, the mounting base 3 has a mounting surface 30 configured on one side z1 in the height direction z, and a back surface 31 configured on the other side z2 in the height direction z.
[0028] 3 and 5, the mounting surface 30 of this embodiment is provided with a positioning structure (not numbered) that protrudes to one side z1 in the height direction z, and a connection support portion 30a that supports a breaker conductor, which will be described later. The positioning structure includes a switching positioning portion 301 for determining the mounting position of a changeover switch 40, which will be described later, relative to the mounting base 3, and a main positioning portion 302 for determining the mounting position of a main breaker 41, which will be described later, relative to the mounting base 3.
[0029] As shown in Figs. 3 and 5, the switching position determining unit 301 extends in the horizontal direction x. As shown in Figs. 1 and 3, in this embodiment, the switching position determining unit 301 is disposed on one side y1 and the other side y2 in the vertical direction y. Thus, the pair of switching position determining units 301, 301 are disposed opposite each other in the vertical direction y. As shown in Figs. 3 and 5, the main trunk position determining unit 302 is disposed on one side x1 in the horizontal direction x of the switching position determining unit 301. The main trunk position determining unit 302 extends in the vertical direction y. Specifically, the pair of main trunk position determining units 302, 302 are disposed opposite each other in the horizontal direction x.
[0030] As shown in Fig. 5, the mounting base 3 of this embodiment is formed with a through hole 30A penetrating in the height direction z. As shown in Fig. 7, the through hole 30A includes a second through hole 30B formed on the other side x2 in the horizontal direction x and a first through hole 30C formed on one side x1 in the horizontal direction x.
[0031] As shown in FIG. 7, the other through hole 30B is a hole that extends in the horizontal direction x and the vertical direction y. The other through hole 30B of this embodiment is a quadrilateral hole in which the vertical direction y is longer than the horizontal direction x. The other through hole 30B of this embodiment is configured to be inclined with respect to the vertical direction y. Specifically, the other through hole 30B is inclined so that it is disposed on one side x1 of the horizontal direction x toward one side y1 of the vertical direction y. The other through hole 30B of this embodiment is configured to have the same length in the horizontal direction x throughout the entire area of the vertical direction y.
[0032] As shown in FIG. 7, the first through hole 30C of this embodiment is configured to have a trapezoidal shape in which the length in the horizontal direction x increases toward the other side y2 in the vertical direction y. The length in the vertical direction y of this first through hole 30C is shorter than that of the other through hole 30B. Moreover, the first through hole 30C is disposed on the one side x1 in the horizontal direction x of the other through hole 30B. Specifically, the first through hole 30C communicates with the other through hole 30B in the horizontal direction x. Furthermore, the other end of the first through hole 30C of this embodiment in the vertical direction y is disposed at the same position as the other end of the other through hole 30B in the vertical direction y. Thus, the through hole 30A of this embodiment is configured to have a substantially L-shape when viewed in the height direction.
[0033] 5, the through hole 30A in this embodiment is disposed on one side x1 in the horizontal direction relative to the trunk positioning portion 302. Also, the through hole 30A is disposed on the other side y2 in the vertical direction y relative to the connection support portion 30a.
[0034] The mounting base 3 is configured to be shorter than the storage main body 201 in the vertical direction y and the horizontal direction x. The mounting base 3 is attached to the storage main body 201 from one side Z1 in the front-rear direction Z. As a result, the mounting base 3 is disposed in the housing 2. Specifically, as shown in Figs. 3 and 4, the mounting base 3 is attached to the storage main body 201 so that the rear surface 31 is the other side Z2 in the front-rear direction Z and the mounting surface 30 is the one side Z1 in the front-rear direction Z. Also, as shown in Fig. 1, the mounting base 3 is disposed on one side X1 in the first direction X with respect to a part of the insertion hole 20a. Furthermore, as shown in Fig. 3, in the mounting base 3 attached to the storage main body 201, the switching positioning portion 301 is disposed on the other side X2 in the first direction X with respect to the main positioning portion 302.
[0035] The circuit structure is for configuring an electric path in the electric device built-in board 1. This circuit structure is disposed inside a housing 2. As shown in Figs. 2 and 3, the circuit structure of this embodiment includes a plurality of electric devices 4 and a connecting conductor 5 that electrically connects the plurality of electric devices 4.
[0036] 1, in this embodiment, the multiple electric devices 4 are change-over switches 40 and breakers (specifically, a main breaker 41 and branch breakers 42). Therefore, the electric device built-in panel 1 of this embodiment is a change-over switch built-in panel that has the change-over switch 40 built-in.
[0037] The changeover switch 40 is for switching the power supply system that supplies electricity to a load between a first power supply and a second power supply. The changeover switch 40 is disposed at one end in the height direction z, and has a front part (not numbered) that extends in the horizontal direction x and the vertical direction y. As shown in FIG. 5, the front part of this embodiment has cutouts at ends on one side y1 and the other side y2 in the vertical direction y. Therefore, the front part has a front main body part 40A configured as one end in the height direction z, a front base part 40B, and a rear base part 40C.
[0038] As shown in Fig. 5, the front base portion 40B is disposed on one side y1 and the other side y2 in the vertical direction y from the front main body portion 40A. The front base portion 40B is disposed on the other side z2 in the height direction z from the front main body portion 40A. The rear base portion 40C is disposed on the other side z2 in the height direction z from the two front base portions 40B, 40B. This rear base portion 40C is disposed on the other side y2 in the vertical direction y from the front base portion 40B on the other side y2.
[0039] The front base portion 40B and the rear base portion 40C are provided with wall portions protruding to one side z1 in the height direction z. As shown in Fig. 3, the wall portions include a pair of side wall portions 400, 400 arranged in the lateral direction x, and a partition wall portion 401 arranged between the pair of side wall portions 400, 400.
[0040] As shown in Fig. 1, the changeover switch 40 includes a first side terminal portion 40a electrically connectable to a first conductor, a second side terminal portion 40b electrically connectable to a second conductor, and a load side terminal portion 40c electrically connectable to a load conductor. The changeover switch 40 of this embodiment has a changeover handle (not numbered) for switching the power source to the first power source or the second power source. Therefore, the changeover switch 40 of this embodiment is a manual changeover switch. The changeover handle is provided on the front main body portion 40A.
[0041] The first side terminal portion 40a, the second side terminal portion 40b, and the load side terminal portion 40c are conductive. As shown in Figs. 1, 2, and 3, in this embodiment, the first side terminal portion 40a, the second side terminal portion 40b, and the load side terminal portion 40c are so-called "insertion type" terminal portions that are fixed by inserting a screw. In addition, the first side terminal portion 40a, the second side terminal portion 40b, and the load side terminal portion 40c in this embodiment include a terminal portion for a first phase and a terminal portion for a second phase that are arranged side by side in the horizontal direction x. Therefore, the changeover switch 40 in this embodiment is a changeover switch 40 used in a single-phase two-wire circuit.
[0042] 1, the second terminal portion 40b is provided on one side y1 in the vertical direction y. In this embodiment, the first-phase and second-phase terminal portions are disposed between the side wall portion 400 and the partition wall portion 401 in the front base portion 40B disposed on one side y1 in the vertical direction y.
[0043] As shown in Figs. 2 and 5, the first side terminal portion 40a and the load side terminal portion 40c are provided on the other side y2 in the vertical direction y. In this embodiment, the first side terminal portion 40a is provided on the front side base portion 40B, and the load side terminal portion 40c is provided on the rear side base portion 40C. Therefore, the load side terminal portion 40c is disposed on the other side z2 in the height direction z than the first side terminal portion 40a. Also, as shown in Fig. 3, in the first side terminal portion 40a and the load side terminal portion 40c, the first phase terminal portion and the second phase terminal portion are disposed between the side wall portion 400 and the partition wall portion 401.
[0044] As described above, in the first side terminal portion 40a, the second side terminal portion 40b, and the load side terminal portion 40c, the terminal portion for the first phase and the terminal portion for the second phase are arranged between the side wall portion 400 and the partition wall portion 401. Therefore, in this embodiment, the first side terminal portion 40a, the second side terminal portion 40b, and the load side terminal portion 40c are arranged so as to be exposed toward one side z1 in the height direction z. Note that, as shown in Figs. 1, 2, and 3, in this embodiment, the first side terminal portion 40a and the second side terminal portion 40b are covered by the terminal cover portion 4X from one side z1 in the height direction z.
[0045] The changeover switch 40 is installed on the mounting base 3. As shown in Figs. 1 and 3, in this embodiment, the changeover switch 40 is installed on the mounting base 3 in a state where the horizontal direction x, vertical direction y, and height direction z are aligned with the first direction X, the second direction Y, and the front-rear direction Z, respectively, so that the changeover handle is located on one side Z1 in the front-rear direction Z, the first side terminal portion 40a is located on the other side Y2 in the second direction Y, and the second side terminal portion 40b is located on one side Y1 in the second direction Y. Here, the changeover switch 40 of this embodiment is configured such that the length in the vertical direction y is shorter than the distance between the pair of changeover positioning parts 301, 301. Therefore, the changeover switch 40 is disposed between the pair of changeover positioning parts 301, 301. Specifically, the changeover switch 40 of this embodiment is installed on the mounting base 3 in a state where one side y1 and the other side y2 in the vertical direction y are abutted against the pair of changeover positioning parts 301, 301. Therefore, the changeover switch 40 installed on the mounting base 3 is disposed inside the housing 2.
[0046] The breaker is disposed on the load side of the electric circuit relative to the changeover switch 40. As shown in FIG.
[0047] The main breaker 41 is for cutting off an electric circuit to protect equipment on the load side. As shown in Figs. 1 and 2, the main breaker 41 includes a main input terminal section 41a and a main output terminal section 41b. The main input terminal section 41a and the main output terminal section 41b are conductive. As shown in Fig. 2, the main input terminal section 41a of this embodiment is a so-called "insertion type" terminal section that is fixed by inserting a screw. In this embodiment, the main output terminal section 41b is also a so-called "insertion type" terminal section. In addition, the main input terminal section 41a and the main output terminal section 41b of this embodiment include a terminal section for a first phase and a terminal section for a second phase that are arranged side by side in the horizontal direction x.
[0048] 1 and 2, in the main breaker 41 of this embodiment, the main output terminal portion 41b is disposed on one side y1 in the vertical direction y, and the main input terminal portion 41a is disposed on the other side y2 in the vertical direction y. The main input terminal portion 41a and the main output terminal portion 41b are disposed in an exposed state on one side z1 in the height direction z.
[0049] As shown in Figs. 3, 4 and 5, the main breaker 41 of this embodiment is provided with a main mounting portion 41c that is used when installing the main breaker 41 on the mounting base 3. The main mounting portion 41c is configured as a plate extending in the horizontal direction x and the vertical direction y. The main mounting portion 41c is also formed with a screw hole for inserting a screw in the height direction z. The main mounting portion 41c is provided at the end of the other side y2 of the main breaker 41 in the vertical direction y. Furthermore, the length of the main mounting portion 41c in the horizontal direction x is shorter than the separation distance between the pair of main positioning portions 302, 302. Therefore, the main mounting portion 41c can be positioned between the pair of main positioning portions 302, 302.
[0050] The main breaker 41 is installed on the mounting base 3. As shown in Figs. 1 and 2, in this embodiment, the main breaker 41 is installed on the mounting base 3 so that the main output terminal portion 41b is located on one side Y1 of the second direction Y and the main input terminal portion 41a is located on the other side Y2 of the second direction Y. Also, as shown in Figs. 3, 4 and 5, the main breaker 41 is installed on the mounting base 3 so that the main mounting portion 41c is located between a pair of main positioning portions 302, 302. Therefore, the main breaker 41 installed on the mounting base 3 is arranged within the housing 2.
[0051] 1, 2 and 3, when the main breaker 41 is installed on the mounting base 3, it is disposed on one side X1 in the first direction X with respect to the changeover switch 40. Specifically, in the first direction X, the main input terminal portion 41a is disposed on one side X1 of the first side terminal portion 40a and the load side terminal portion 40c, and the main output terminal portion 41b is disposed on one side X1 of the second side terminal portion 40b.
[0052] The branch breaker 42 is for protecting equipment on the load side by cutting off the electric circuit. The branch breaker 42 is arranged on the load side of the electric circuit relative to the main breaker 41. As shown in Fig. 1, the branch breaker 42 is arranged on one side X1 in the first direction X relative to the main breaker 41. In this embodiment, a plurality of (specifically, two) branch breakers 42, 42 are arranged side by side in the second direction Y.
[0053] The connection conductor 5 electrically connects the multiple electrical devices 4. As shown in Figs. 2, 3 and 5, the connection conductor 5 of this embodiment includes a switching conductor 50 that electrically connects the changeover switch 40 and the main breaker 41, and a breaker conductor (not shown and not numbered) that electrically connects the main breaker 41 (specifically, the main output terminal portion 41b) and the branch breaker 42.
[0054] The switching conductor 50 is made of a conductive material. In this embodiment, the switching conductor 50 is made of a conductive plate-like material (specifically, a copper plate). As shown in FIG. 2, the switching conductor 50 includes a conductor main body 500, a switching conductive part 501 connected to the load side terminal 40c, and a main conductive part 502 connected to the main input terminal 41a.
[0055] As shown in Figs. 3 and 5, in this embodiment, the switching conductor 50 for the first phase and the switching conductor 50 for the second phase are provided. Specifically, the switching conductor 50 for the first phase is disposed on one side Z1 in the front-rear direction Z, and the switching conductor 50 for the second phase is disposed on the other side Z2 in the front-rear direction Z. In addition, in this embodiment, the shape of the conductor body 500 is different between the switching conductor 50 for the first phase and the switching conductor 50 for the second phase. Specifically, as shown in Fig. 3, the conductor body 500 in the switching conductor 50 for the first phase is configured in a stepped shape (specifically, in a three-step shape) that is disposed closer to the one side Z1 in the front-rear direction Z as it proceeds to the one side X1 in the first direction X. In contrast, the conductor body 500 in the switching conductor 50 for the second phase is configured in a flat plate shape extending along the first direction X.
[0056] The switching conductive portion 501 and the main conductive portion 502 are terminal portions of a so-called "insertion type" that are fixed by inserting a screw. As shown in Fig. 2, the switching conductive portion 501 and the main conductive portion 502 extend from the conductor main body portion 500 to one side Y1 in the second direction Y. Specifically, the switching conductive portion 501 is disposed on the other side X2 in the first direction X, and the main conductive portion 502 is disposed on one side X1 in the first direction X. The conductor main body portion 500 is connected to the switching conductive portion 501 and the main conductive portion 502, and extends in the first direction X.
[0057] The switching conductor 50 is installed in the accommodation section 20 after the changeover switch 40 and the main breaker 41 are installed. In the first-phase switching conductor 50, the switching conductive part 501 is connected to the load side terminal part 40c for the first phase, and the main conductive part 502 is connected to the main input terminal part 41a for the first phase. In the second-phase switching conductor 50, the switching conductive part 501 is connected to the load side terminal part 40c for the second phase, and the main conductive part 502 is connected to the main input terminal part 41a for the second phase. As shown in FIG. 2, the conductor main body part 500 is arranged to extend in the first direction X on the other side Y2 of the second direction Y than the changeover switch 40 and the main breaker 41. Therefore, in this embodiment, the changeover switch 40 and the main breaker 41 can be electrically connected by the switching conductor 50. Furthermore, as shown in FIG. 5, the switching conductor 50 is arranged to be exposed to one side Z1 in the front-rear direction Z when installed in the accommodation section 20. Therefore, it is possible to check the switching conductor 50 from one side in the front-rear direction Z.
[0058] As described above, the load side terminal portion 40c, the main input terminal portion 41a, and the switching conductor 50 are conductive. Therefore, in this embodiment, the load side terminal portion 40c, the main input terminal portion 41a, and the switching conductor 50 form a conductive portion in the circuit structure. As shown in Fig. 5, this conductive portion is exposed toward one side Z1 in the front-rear direction Z, which is the front side of the circuit structure.
[0059] The conductive cover 6 is for covering the conductive portion from the front side. As shown in FIG. 2, the conductive cover 6 of this embodiment is configured to cover the load side terminal portion 40c, the main input terminal portion 41a, and the switching conductor 50.
[0060] The conductive cover 6 is made of a plate-like member. The conductive cover 6 is made of an insulating member (specifically, resin). As shown in Figs. 2 and 3, the conductive cover 6 includes a cover portion 7 that covers the conductive portion, and a cover attachment portion 8 that is used to attach the conductive cover 6 to the attachment base 3.
[0061] As shown in Figure 2, the covering portion 7 of this embodiment includes a switching covering portion 70 that covers the load side terminal portion 40c and the switching conductive portion 501, a main trunk covering portion 71 that covers the main trunk input terminal portion 41a and the main trunk conductive portion 502, and a covering main body portion 72 that covers the conductor main body portion 500 and connects the switching covering portion 70 and the main trunk covering portion 71.
[0062] The switching cover 70 is formed in a flat plate shape extending in the horizontal direction x and the vertical direction y. The switching cover 70 of this embodiment is formed to have a length in the horizontal direction x that allows it to cover the first-phase and second-phase terminal portions of the load-side terminal portion 40c. As shown in Figs. 2 and 3, the switching cover 70 of this embodiment is formed so as to be attachable to the side wall portion 400 of the rear base portion 40C from one side z1 in the height direction z.
[0063] The main trunk covering portion 71 is configured in a flat plate shape extending in the horizontal direction x and the vertical direction y. As shown in Fig. 2, the main trunk covering portion 71 is configured to have a length in the horizontal direction x that allows it to cover the first-phase and second-phase terminal portions of the main trunk input terminal portion 41a. In addition, the main trunk covering portion 71 is disposed on one side x1 in the horizontal direction x of the switching covering portion. As shown in Figs. 3 and 5, the main trunk covering portion 71 of this embodiment is disposed on one side z1 in the height direction z of the switching covering portion 70.
[0064] The covering body portion 72 is configured to have a length capable of covering the conductor body portion 500 in the horizontal direction x. In this embodiment, the covering body portion 72 is configured in a stepped shape (specifically, in a two-step shape) that is disposed on one side z1 in the height direction z as it proceeds to one side x1 in the horizontal direction x. The covering body portion 72 is disposed on the other side y2 in the vertical direction y relative to the switching covering portion 70 and the main trunk covering portion 71. Specifically, the covering body portion 72 is connected to the main trunk covering portion 71 on one side x1 in the horizontal direction x, and connected to the switching covering portion 70 on the other side x2 in the horizontal direction x.
[0065] 6, the cover attachment part 8 is made of a plate-like member that has a thickness in the horizontal direction x and extends in the vertical direction y and the height direction z. The cover attachment part 8 includes a locking part 80 disposed on the other side z2 in the height direction z, and a connecting part 81 that connects the covering part 7 and the locking part 80.
[0066] The locking portion 80 includes a neck portion 800 extending in the height direction z and a locking body portion 801 extending from the neck portion 800. As shown in FIG. 6, the neck portion 800 extends in the vertical direction y and the height direction z. The neck portion 800 is shorter than the other through hole 30B and the one through hole 30C in the horizontal direction x and the vertical direction y. Therefore, the neck portion 800 is configured to be insertable into the other through hole 30B and the one through hole 30C. Furthermore, the neck portion 800 of this embodiment is longer than the mounting base 3 in the height direction z. Therefore, as shown in FIG. 4, the neck portion 800 is configured to be insertable into the through hole 30A of the mounting base 3.
[0067] 4 and 6, the locking body 801 of this embodiment extends from the neck 800 to one side y1 in the vertical direction y. In this embodiment, the locking body 801 is provided at the other end of the neck 800 in the height direction z. Therefore, the locking part 80 of this embodiment is configured to be substantially L-shaped when viewed in the horizontal direction.
[0068] The length in the vertical direction y of the neck portion 800 and the locking main body portion 801 combined is shorter than the length in the vertical direction y of the other through hole 30B. Therefore, the locking portion 80 is configured to be insertable into and removable from the other through hole 30B. In other words, the other through hole 30B is configured to allow the neck portion 800 and the locking main body portion 801 to be inserted and removable. On the other hand, the length in the vertical direction y of the neck portion 800 and the locking main body portion 801 combined is shorter than the length in the vertical direction y of the one through hole 30C. Therefore, the locking portion 80 is configured to be non-insertable from and removable from the one through hole 30C.
[0069] 6, the connecting portion 81 of this embodiment is a plate-like member configured to be longer in the height direction z than in the vertical direction y. The connecting portion 81 of this embodiment includes one connecting portion 810 disposed on one side z1 in the height direction z, and the other connecting portion 811 disposed on the other side z2 in the height direction z.
[0070] The one connecting part 810 extends in the height direction z and the vertical direction y. One end of the one connecting part 810 in the height direction z is connected to one end of the cover part 7 in the horizontal direction x. The other end of the one connecting part 810 in the height direction z of this embodiment is disposed on one side x1 or the other side x2 in the horizontal direction x relative to the one end of the height direction z. Specifically, the one connecting part 810 is inclined with respect to the height direction z so that the other end of the one connecting part 810 in the height direction z is disposed on one side x1 in the horizontal direction x relative to the one end of the height direction z. Therefore, as shown in FIG. 3, the cover attachment part 8 in this embodiment is disposed so as to be inclined with respect to the height direction z.
[0071] The other connection part 811 is connected to the one connection part 810 and the neck part 800 in the height direction z. In this embodiment, the other connection part 811 is shorter than the one connection part 810 in the vertical direction y. Therefore, as shown in FIG. 6, in this embodiment, the other end in the vertical direction y on the other side z2 in the height direction z of the connecting part 81 is cut out. Also, the other connection part 811 is longer than the locking part 80 in the vertical direction y. Furthermore, the other connection part 811 is longer than the through hole 30A in the vertical direction y. Therefore, the connecting part 81 cannot be inserted into the through hole 30A.
[0072] The connecting portion 81 of this embodiment is configured to be elastically deformable in a direction intersecting the height direction z. Specifically, the connecting portion 81 is configured to be elastically deformable so as to bend within an elastic range so as to move the other side z2 in the height direction z to the other side x2 in the lateral direction x. Also, the connecting portion 81 is elastically deformable so as to be twisted around the height direction z within the elastic range.
[0073] The conductive cover 6 is placed in the housing 2 after the circuit structure is placed in the housing 2. When placing the conductive cover 6 in the housing 2, the conductive portion is covered with the covering portion 7, and the cover attachment portion 8 is attached to the mounting base 3. Therefore, in this embodiment, the mounting base 3 is the attachment portion for attaching the conductive cover 6.
[0074] 2, when covering the conductive portion with the covering portion 7, the covering portion 7 is disposed on one side Z1 in the front-rear direction Z of the conductive portion so that the switching covering portion 70 covers the load side terminal portion 40c and the switching conductive portion 501, the main trunk covering portion 71 covers the main trunk input terminal portion 41a and the main trunk conductive portion 502, and the covering body portion 72 covers the conductor body portion 500. Here, in this embodiment, when disposing the covering portion 7 on one side Z1 in the front-rear direction Z of the conductive portion, the switching covering portion 70 is attached to the side wall portion 400 of the rear base portion 40C. This fixes the covering portion 7 to the circuit structure.
[0075] When the cover mounting part 8 is attached to the mounting base 3, it is necessary to engage the locking part 80 with the mounting part. First, the connecting part 81 is elastically deformed in a direction intersecting the height direction z. In this embodiment, in order to align the cover mounting part 8 with the height direction z, the other side z2 of the cover mounting part 8 in the height direction z is moved to the other side x2 of the horizontal direction x, and the connecting part 81 is elastically deformed so as to bend. In addition, the connecting part 81 is elastically deformed so as to be twisted around the height direction z so that the other side y2 of the vertical direction y moves to the other side x2 of the horizontal direction x. The twisting of the connecting part 81 causes the locking part 80 to rotate around the height direction z. The locking part 80 is then rotatable between a first rotation position, which is a position before the rotation, and a second rotation position, which is a position after the rotation.
[0076] Here, as shown in Fig. 7, the mounting base 3, which is the mounting part, includes an insertion / removal part 3B in which an insertion / removal hole 30B into which the locking part 80 can be inserted and removed is formed. Therefore, the locking part 80 rotated to the second rotation position by twisting the connecting part 81 can be inserted and removed into the other through hole 30B, which is the insertion / removal hole 30B. Therefore, the locking part 80 is inserted into the other through hole 30B in the front-rear direction Z, which is the insertion / removal direction. Then, as shown in Fig. 8(a), the locking part 80 inserted into the other through hole 30B is disposed at an insertion / removal position where it can be inserted and removed into the other through hole 30B.
[0077] Next, the twist of the connecting portion 81 is released by the elastic force of the connecting portion 81 around the height direction z. As a result, the locking portion 80 inserted into the other through hole 30B rotates from the second rotation position to the first rotation position. As a result, as shown in FIG. 8(b), the locking main body portion 801 is arranged to overlap the back surface 31 of the mounting base 3 in the front-rear direction Z. Therefore, the locking portion 80 in the first rotation position is locked in the removal direction by the removal prevention portion 3b (specifically, the back surface 31 of the mounting base 3) formed in the insertion / removal portion 3B.
[0078] Next, the elastic force of the connecting portion 81 biases the locking portion 80 so as to return the connecting portion 81 to the state before it was bent. Here, as shown in Fig. 7, the mounting base 3, which is the mounting portion, has a locked portion 3C that is locked to the locking portion 80 in the removal direction. Then, due to the bias caused by the elastic deformation of the connecting portion 81, the locking portion 80 moves from the insertion / removal position to a locking position where it is locked to the locked portion 3C in the removal direction.
[0079] 8(c), when the locking portion 80 moves to the locking position, the neck portion 800 is inserted into the one-way through hole 30C, and the locking main body portion 801 is arranged to overlap the back surface 31 of the mounting base 3 in the front-rear direction Z. That is, the neck portion 800 is inserted into the one-way through hole 30C, which is the neck insertion hole 30C formed in the locked portion 3C, and the locking main body portion 801 is locked in the removal direction to the locked main body portion 3c (specifically, the back surface 31 of the mounting base 3) formed in the locked portion 3C and arranged adjacent to the neck insertion hole 30C. In this manner, the cover mounting portion 8 is attached to the mounting base 3.
[0080] On the other hand, when removing the conductive cover 6 from the mounting base 3, the procedure is reversed from that for mounting. That is, the cover portion 7 is removed from the circuit structure, the locking portion 80 is moved from the locking position to the insertion / removal position, and the locking portion 80 is rotated from the second rotation position to the first rotation position. Then, the locking portion 80 is removed from the other through hole 30B.
[0081] As described above, according to this embodiment, the conductive cover 6 can be attached to the mounting portion by moving the locking portion 80 inserted into the insertion / removal hole 30B from the insertion / removal position to the locking position, and the conductive cover 6 can be removed from the mounting portion by moving the locking portion 80 from the locking position to the insertion / removal position and removing it from the insertion / removal hole 30B.
[0082] In addition, in this embodiment, the locking portion 80 at the insertion / removal position is biased toward the locking position by the elastic deformation of the connecting portion 81, so that the locking portion 80 can be easily moved from the insertion / removal position to the locking position.
[0083] In this embodiment, the neck portion 800 and the locking main body portion 801 are inserted into the insertion hole 30B, and then the neck portion 800 is moved to the neck insertion hole 30C, and the locking main body portion 801 is locked to the locked main body portion 3c, thereby allowing the conductive cover 6 to be attached to the attachment portion. Furthermore, the neck portion 800 is moved from the neck insertion hole 30C to the insertion hole 30B, and then the neck portion 800 and the locking main body portion 801 are removed from the insertion hole 30B, allowing the conductive cover 6 to be removed from the attachment portion.
[0084] Furthermore, in this embodiment, in order to insert or remove the locking portion 80 into or from the insertion / removal hole 30B, it is necessary to rotate the locking portion 80 from the first rotation position to the second rotation position. Therefore, for example, it is possible to prevent the locking portion 80 inserted into the insertion / removal hole 30B from coming out of the insertion / removal hole 30B due to vibration during transportation.
[0085] In this embodiment, the locking portion 80 is configured to be substantially L-shaped when viewed in the lateral direction. Therefore, the locking portion 80 can be easily formed in the cover attachment portion 8.
[0086] In this embodiment, the other connection part 811 is shorter than the one connection part 810 in the vertical direction y. As shown in Fig. 6, the other end of the connection part 81 in the vertical direction y on the other side z2 in the height direction z is cut out in the connection part 81 in this embodiment. Therefore, when the cover attachment part 8 is attached to the attachment base 3, interference of the connection part 81 with the frame part 200 can be suppressed.
[0087] In this embodiment, the switching covering part 70 is configured to be attachable to the side wall part 400 of the rear base part 40C from one side z1 in the height direction z. The switching covering part 70 is attached to the side wall part 400 of the rear base part 40C, whereby the covering part 7 is fixed to the circuit structure. This makes it possible to prevent the covering part 7 from rattling relative to the changeover switch 40, and ensures that the covering part 7 covers the conductive part.
[0088] It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.
[0089] In the above embodiment, the mounting base 3 is configured in a rectangular shape with the horizontal direction x being longer than the vertical direction y. However, this is not limited thereto, and the mounting base 3 may be, for example, a square shape with approximately the same length in the horizontal direction x and the vertical direction y. The mounting base 3 may also be a shape other than a square, such as a triangular shape or a circular shape.
[0090] In the above embodiment, the mounting base 3 is the mounting portion, but the present invention is not limited to this. For example, the circuit structure or the housing main body 201 may be provided with a mounting portion.
[0091] Furthermore, in the above embodiment, the circuit structure includes a plurality of electric devices 4 and the connecting conductor 5. However, this is not limited thereto, and the circuit structure may be configured to include at least one electric device 4. Thus, for example, the circuit structure may be configured to include only one electric device 4. In this case, the conductive portion is a terminal portion of the electric device 4. The conductive cover 6 covers the terminal portion, which is the conductive portion.
[0092] In the above embodiment, the electric device 4 is the changeover switch 40 and the breaker. However, the present invention is not limited to this, and the electric device 4 may be, for example, a terminal block having a terminal portion.
[0093] In the above embodiment, the load side terminal portion 40c, the trunk input terminal portion 41a, and the switching conductor 50 constitute the conductive portion. However, this is not limited thereto, and for example, the conductive portion may be constituted by only the switching conductor 50, or by only the load side terminal portion 40c and the trunk input terminal portion 41a. In this case, the conductive cover 6 may be a busbar cover that covers only the switching conductor 50, or a terminal cover that covers only the load side terminal portion 40c and the trunk input terminal portion 41a.
[0094] In the above embodiment, the connecting conductor 5 (specifically, the switching conductor 50) is configured from a conductive plate-like member. However, the present invention is not limited to this, and the connecting conductor 5 may be a conductive linear member (specifically, a conductor wire).
[0095] In the above embodiment, the locking main body 801 extends from the neck 800 to one side y1 in the vertical direction y. However, the locking main body 801 may extend from the neck 800 in a direction intersecting the insertion / removal direction and the movement direction in which the locking portion moves.
[0096] In the above embodiment, the locking portion 80 is configured to move due to elastic deformation of the connecting portion 81. However, the present invention is not limited to this, and the locking portion 80 may be configured to move due to, for example, sliding of the connecting portion 81 relative to the covering portion 7 in the first direction X or the second direction Y.
[0097] The shape of the through hole 30A is not limited to the shape shown in Fig. 7, and may be, for example, a shape as shown in Fig. 9 and 10. Specifically, as shown in Fig. 9 and 10, the other through hole 30B and the one through hole 30C may be formed along the vertical direction y. Also, as shown in Fig. 9, the one through hole 30C may be configured such that the other end in the vertical direction y is disposed on one side y1 of the other end in the vertical direction y of the other through hole 30B, and the one end in the vertical direction y is disposed on one side y1 of the one end in the vertical direction y of the other through hole 30B.
[0098] In the above embodiment, the locking portion 80 is moved by utilizing both the bending and twisting of the connecting portion 81. However, this is not limited thereto, and as shown in Fig. 10, for example, only the bending of the connecting portion 81 may be utilized to move the locking portion 80 only in the first direction X. Furthermore, as shown in Figs. 9(a), (b-1), (b-2), (c), and (d), the locking portion 80 inserted into the through hole 30A may be moved in the first direction X or the second direction Y to move the locking portion 80 between the insertion / removal position and the locking position without utilizing the elastic deformation of the connecting portion 81.
[0099] As shown in FIG. 11, the locking portion 80 may include a pair of necks 800, 800 facing each other in the vertical direction y, and a locking body portion 801 extending between the pair of necks 800, 800. A spacer portion 82 may be formed between the locking portion 80 and the connecting portion 81. As shown in FIG. 12, the shape of the through hole 30A may be changed according to the shape of the locking portion 80. Specifically, the other through hole 30B may be configured to allow the pair of necks 800, 800 and the locking body portion 801 to be inserted therein, and two one through holes 30C may be arranged in the vertical direction y with the locked body portion 3c sandwiched therebetween. Then, as shown in FIG. 12(a), the locking portion 80 is inserted into the other through hole 30B, and then the locking portion 80 is moved to one side X1 in the first direction X. As a result, the pair of neck portions 800, 800 are inserted into the two one-way through holes 30C, 30C, respectively, and the locking main body portion 801 is locked to the locked main body portion 3c in the removal direction.
