Description

Technical Field

[0001] The present invention relates to a housing formed by connecting wall bodies.

Background Art

[0002] In a switchboard or the like provided with predetermined electrical equipment, it is configured with a box-shaped housing. In such a housing, a configuration in which two or more wall bodies are arranged and connected on the same plane or in orthogonal directions is known. A configuration for connecting wall bodies is disclosed in Patent Documents 1 and 2.

[0003] Patent Document 1 discloses a structure in which a flange portion is formed on a case member serving as two wall bodies, and a clip is attached to and connected to such a flange portion. The clip includes an elongated plate-like portion and engaging claw portions formed on both sides in the short-side direction of the plate-like portion and engaging with the flange portion.

[0004] In Patent Document 1, when connecting two case members, the clip is applied so as to cover the two flange portions in the combined state from the outside, and the plate-like portion is strongly pushed in. As a result, the entire clip is elastically deformed, and the engaging claw portions are deformed so as to expand outward and then return to their original shape, thereby engaging with the flange portion, and the two flange portions are clamped by the clip.

[0005] Patent Document 2 connects two wall bodies via a sheath member. A bent portion is provided on one side of the wall body, and a locking edge portion is formed by bending the leading edge of the bent portion at an acute angle toward the wall body side. The sheath member has a predetermined length and is formed in a substantially arrow-shaped cross section. The sheath member includes two parallel edge portions that project while maintaining a gap from a sheath portion having a substantially triangular insertion hole.

[0006] In Patent Document 2, when connecting two wall bodies, the two bent portions are positioned in contact with each other so that their locking edges are back to back. In this state, the locking edges are inserted into the insertion holes of the sheath portion of the sheath member, and the sheath member is attached across the two bent portions. This connects the two wall bodies by sandwiching the bent portions with the parallel end edges, maintaining the state in which the two bent portions are in contact. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Utility Model Publication No. 6-51514 [Patent Document 2] Japanese Patent Publication No. 2001-65068 [Overview of the initiative] [Problems that the invention aims to solve]

[0008] In Patent Document 1, the force required to press the plate-shaped part in order to elastically deform the entire clip becomes large, which increases the workload involved in attaching the clip and, consequently, connecting the two case members.

[0009] Furthermore, in Patent Document 2, the locking edge of the wall is inserted into the insertion hole of the sheath from either end in the extension direction of the bent portion and slid to attach the sheath member. As a result, it is necessary to secure space at both ends in the extension direction of the bent portion to allow the sheath member to be inserted, which leads to structural constraints such as shortening the bent portion or making the housing itself larger.

[0010] This invention has been made in view of these circumstances, and aims to provide a housing that can suppress the increased burden of the work of connecting two wall bodies and alleviate structural constraints. [Means for solving the problem]

[0011] A housing according to one aspect of the present invention is a housing composed of a plurality of walls, wherein at least two adjacent walls are connected via a connector, the walls comprising a main surface portion that forms the outer circumferential surface of the housing, and a joining surface portion that is connected to the outer edge of the main surface portion as the base end and has its tip on the inside or outside of the housing, the joining surface portion comprising a hole through which the internal spaces communicate with each other when the joining surface portions of the two walls are in contact with each other, the connector comprising an insertion piece that is inserted into the hole in the two walls, and a notch formed in the insertion piece, the notch being provided so as to fit into the forming edge of the hole and sandwich the joining surface portions of the two walls when the insertion piece is inserted into the hole in the thickness direction of the joining surface portion of each of the two walls. The hole is formed in a region including the boundary position between the joining surface portion and the main surface portion, and the insertion piece portion makes surface contact with the main surface portion while the notch portion sandwiches the joining surface portion in the two wall bodies. It is characterized by the following. Another embodiment of the present invention is a housing composed of a plurality of walls, wherein at least two adjacent walls are connected via a connector, the walls comprising a main surface portion that forms the outer circumferential surface of the housing and a joining surface portion that is connected to the outer edge of the main surface portion as a base end and has its tip on the inside or outside of the housing, the joining surface portion having a hole through which the internal spaces communicate with each other when the joining surface portions of two of the walls are in contact, and the connector is the same for the two of the walls The wall comprises an insertion piece that is inserted into a hole, a notch formed in the insertion piece, and a support piece that is connected to the insertion piece and oriented in a direction intersecting the insertion piece, and that makes surface contact with the joining surface, wherein the notch is provided so as to fit into the forming edge of the hole in each of the two wall bodies when the insertion piece is inserted into the hole in the thickness direction of the joining surface, thereby sandwiching the joining surface of the two wall bodies, and a single support piece has multiple insertion pieces formed on it. A housing in yet another aspect of the present invention is a housing composed of a plurality of walls, wherein at least two adjacent walls are connected via a connector, the walls comprising a main surface portion that forms the outer circumferential surface of the housing, and a joining surface portion that is connected to the outer edge of the main surface portion as a base end and has its tip on the inside or outside of the housing, the joining surface portion having a hole through which the internal spaces communicate with each other when the joining surface portions of the two walls are in contact, the connector comprising an insertion piece that is inserted into the hole in the two walls, and the insertion piece The wall comprises a notch formed in the section, and a support piece that is connected to the insertion piece and oriented in a direction intersecting the insertion piece, and making surface contact with the joining surface, wherein the notch is provided so as to fit into the forming edge of the hole in each of the two wall bodies when the insertion piece is inserted through the hole in the thickness direction of the joining surface, thereby sandwiching the joining surface of the two wall bodies, and further comprises a reinforcing piece that is located on the opposite side of the insertion piece from the support piece in the thickness direction of the support piece, and makes surface contact with the main surface. [Effects of the Invention]

[0012] According to the present invention, when connecting multiple wall bodies with a connector, the insertion piece can be inserted into the hole by moving the connector in the thickness direction of the joining surface. Subsequently, by moving the connector so as to slide the insertion piece inside the hole, the notch is fitted into the formed edge of the hole, sandwiching the two joining surfaces, and the wall bodies can be connected by the connector. This eliminates the need for an operating force that would elastically deform the connector itself, thereby reducing the burden on the work of connecting the wall bodies, and furthermore, it can alleviate structural constraints such as securing space for the connector to slide on both sides in the extending direction of the joining surface.

Mode for Carrying Out the Invention

[0014] Hereinafter, the housing according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Note that the present invention is not limited to the following embodiments, and can be appropriately modified and implemented within the scope of not changing the gist thereof. In the following figures, for convenience of explanation, some configurations may be omitted. Also, in the following description, unless otherwise specified, "up", "down", "left", "right", "front", and "rear" are used based on the directions indicated by the arrows in each figure. However, the orientation of each configuration is only an example and can be changed to any orientation.

[0015] FIG. 1 is a schematic perspective view of a housing according to an embodiment. The housing 10 shown in FIG. 1 has a predetermined accommodation space inside, and houses, for example, predetermined electrical equipment such as a switchboard, a control panel, and a circuit breaker (not shown) in the accommodation space. The housing 10 is formed by connecting a plurality of panel-shaped wall bodies. More specifically, the housing 10 includes an upper wall body 11, a lower wall body 12, and a plurality of side wall bodies 20 provided between the upper wall body 11 and the lower wall body 12. In the present embodiment, a plurality (four in FIG. 1) of side wall bodies 20 are provided side by side on both the front and rear sides of the upper wall body 11 and the lower wall body 12. Each of the wall bodies 11, 12, and 20 is not particularly limited, but can be formed of a metal plate such as a steel plate, for example.

[0016] Subsequently, the connection structure of two adjacent side wall bodies 20 in the left-right direction will be described. Here, as a representative example, the connection structure of two side wall bodies 20 indicated by reference numerals 20A and 20B in FIG. 1 will be described. Hereinafter, the side wall body 20 located relatively on the left side and indicated by reference numeral 20A will be referred to as the first wall body 20A, and the side wall body 20 located relatively on the right side and indicated by reference numeral 20B will be referred to as the second wall body 20B.

[0017] FIG. 2 is a perspective view for explaining two adjacent side wall bodies in the left-right direction in the embodiment. FIG. 3 is an exploded perspective view for explaining the connection structure of the wall bodies in the embodiment. As shown in FIGS. 2 and 3, the right end portion of the first wall body 20A and the left end portion of the second wall body 20B are formed by being bent and are connected adjacent to each other. The first wall body 20A and the second wall body 20B each include a main surface portion 21 and a joining surface portion 22.

[0018] Here, the joining surface portion 22 is formed on both the left and right sides or one end side of the left and right of the side wall body 20 according to the installation position of the side wall body 20 in the housing 10. In FIGS. 2 to 10, the case where the joining surface portion 22 is formed at the right end portion of the first wall body 20A and the left end portion of the second wall body 20B will be described.

[0019] The main surface portion 21 is provided parallel to the vertical and horizontal directions and forms the outer circumferential surface of the housing 10 (see Figure 1). The main surface portion 21 has a rectangular shape that is substantially the same as the planar shape of the first wall 20A and the second wall 20B, and has two long sides extending vertically on both the left and right sides.

[0020] The joining surface portion 22 is formed projecting rearward (inward into the housing 10) from the outer edge forming the long side of the main surface portion 21. Therefore, the joining surface portion 22 is connected to the outer edge side of the main surface portion 21 as its base end and has its tip facing inward into the housing 10. The joining surface portion 22 is oriented in a direction approximately perpendicular to the main surface portion 21. Furthermore, the joining surface portion 22 has a shape that extends along the outer edge forming the long side of the main surface portion 21. In other words, the joining surface portion 22 is formed with the vertical direction as its extension direction.

[0021] When forming the housing 10, the first wall 20A and the second wall 20B are arranged so that their respective main surfaces 21 are on the same plane and their respective joining surfaces 22 are in contact with each other (as shown in Figure 3). In this state, the leading edges (rear ends) of the joining surfaces 22 of the first wall 20A and the second wall 20B are positioned at the same location in the front-to-back direction and are aligned in the left-to-right direction.

[0022] The first wall 20A and the second wall 20B are provided with holes 22a that serve as slot holes (the holes 22a of the first wall 20A are not shown in Figure 3). Multiple holes 22a (three in this embodiment) are formed in the vertical direction in the first wall 20A and the second wall 20B.

[0023] The holes 22a extend in the vertical direction, which is the direction in which the outer edge of the main surface portion 21 extends. The holes 22a are also formed in a region that includes the corner portion, which is the boundary position between the joining surface portion 22 and the main surface portion 21. In the state shown in Figure 3, the holes 22a of the first wall 20A and the second wall 20B are formed at the same position in the vertical and front-to-back directions, and the internal spaces are mutually connected in the left-to-right direction (see Figure 7A). In this state, the connector 30 is attached across the first wall 20A and the second wall 20B.

[0024] The connector 30 is made of a metal material such as aluminum or stainless steel, or an appropriate resin material. As shown in Figure 3, the connector 30 has a single support piece 31 that is flat or plate-shaped, with the vertical direction as the longitudinal direction, the front-to-back direction as the short direction, and the left-to-right direction as the thickness direction. The connector 30 also has a plurality of insertion pieces 32 and a plurality of reinforcing pieces 33 that are formed in conjunction with the front end side of the support piece 31 and protrude in the left-to-right direction with the front-to-back direction as the thickness direction. In other words, the support piece 31 is formed facing the front-to-back direction, which intersects with the insertion pieces 32 and the reinforcing pieces 33.

[0025] The vertical length of the support piece 31 extends over approximately the entire vertical length of the joint surface 22 in the first wall 20A and the second wall 20B. More specifically, it is formed to be slightly shorter than the joint surface 22 so as not to protrude from the upper and lower ends of the joint surface 22. In addition, round holes 31a are formed on both the upper and lower sides of the support piece 31. Here, round holes 22b are also formed on both the upper and lower sides of the joint surface 22 of the first wall 20A and the second wall 20B (see Figure 2). In the vertical direction, the distance between the two round holes 31a of the support piece 31 and the distance between the two round holes 22b of the joint surface 22 are set to be the same, and fastening members 38 (see Figure 10) can be inserted through each of the round holes 31a and 22b.

[0026] Multiple insertion pieces 32 are formed on a single support piece 31 at predetermined intervals in the longitudinal direction (vertical direction) (three in this embodiment). The insertion pieces 32 are formed at vertical intervals that are the same as those of the holes 22a in the first wall 20A and the second wall 20B. In other words, each hole 22a is formed at a vertical position corresponding to the formation position of the three insertion pieces 32. In this embodiment, the spacing between the upper insertion piece 32 and the central insertion piece 32 is set to be the same as the spacing between the central insertion piece 32 and the lower insertion piece 32.

[0027] The insertion piece 32 is connected to the front end of the support piece 31 and is formed to protrude to the left such that the angle between it and the support piece 31 is approximately right angle. Therefore, the right end of the insertion piece 32, which is connected to the front end of the support piece 31, is considered the base end, and the left end on the opposite side is considered the tip end.

[0028] Multiple reinforcing pieces 33 are formed on a single support piece 31 at predetermined intervals in the longitudinal direction (vertical direction) (four in this embodiment). The insertion piece 32 and the reinforcing pieces 33 are formed at different vertical positions. Therefore, when viewed from the front-to-back direction, the insertion piece 32 and the reinforcing pieces 33 are formed alternately in the vertical direction. In other words, the reinforcing pieces 33 are provided on both the upper and lower sides of the insertion piece 32.

[0029] The reinforcing piece 33 is formed in conjunction with the front end of the support piece 31 and is located on the opposite side of the insertion piece 32, sandwiching the support piece 31 in the left-right direction. The reinforcing piece 33 is formed to protrude to the right such that the angle between it and the support piece 31 is approximately right angle, and is positioned in the same front-rear position as the insertion piece 32, and is provided on the same plane as the insertion piece 32. The left end of the reinforcing piece 33, which is connected to the front end of the support piece 31, is considered the base end, and the right end on the opposite side is considered the tip end.

[0030] Here, the vertical lengths (length in the vertical direction) of the support piece 31, insertion piece 32, and reinforcing piece 33 will be described. Of the four reinforcing pieces 33, the two reinforcing pieces 33 on both the upper and lower sides are formed to have a shorter vertical length than the insertion piece 32, while the other two reinforcing pieces 33 are formed to have a longer vertical length than the insertion piece 32.

[0031] In the connector 30, the sum of the vertical lengths of all four reinforcing pieces 33 is longer than the sum of the vertical lengths of all three insertion pieces 32. Furthermore, the insertion pieces 32 and reinforcing pieces 33 are formed only on the support piece 31, not the entire vertical length. As a result, in the connector 30, the vertical lengths are increased in the following order: the sum of the vertical lengths of all insertion pieces 32, the sum of the vertical lengths of all reinforcing pieces 33, and the overall vertical length of the support piece 31.

[0032] Figure 4 is a rear view of the state just before inserting the insertion piece into the hole in each wall in the embodiment. Figure 5 is a rear view of the state immediately after inserting the insertion piece into the hole in each wall in the embodiment. Figure 6 is a rear view of the state in which the notch is fitted into the hole in each wall in the embodiment. In Figures 4 to 6, only the joint surface portion 22 of the first wall 20A and the second wall 20B is shown in a front cross-sectional view at the position where the hole 22a is formed.

[0033] As shown in Figures 4 and 5, the insertion piece 32 is inserted through the holes 22a of the first wall 20A and the second wall 20B from the left-right direction (thickness direction of the joint surface 22). A notch 35 is formed on the lower end side near the base end (right end) of each insertion piece 32. The notch 35 is formed in an L-shape that opens downwards at a position adjacent to the left surface of the support piece 31.

[0034] The left-right width of the notch 35 is formed to be the same as or slightly larger than twice the thickness of the joining surface 22. As a result, as shown in Figure 6, when the insertion piece 32 is inserted through each hole 22a, the notch 35 fits into the lower edge of the hole 22a, and the two joining surface 22 can be sandwiched between the notch 35. More specifically, with the hole 22a fitted into the notch 35, the two joining surface 22 that are in surface contact with the notch 35 and the support piece 31 can be sandwiched from the left and right directions, thereby restricting the relative displacement of each wall 20A, 20B in the left-right direction.

[0035] Figure 7A is a partial cross-sectional view of Figure 4, and Figure 7B is a partial cross-sectional view of Figure 6. As shown in Figures 7A and 7B, the thickness (front-to-back width) of the insertion piece 32 is formed to be the same as or slightly smaller than the front-to-back dimension between the rear surface of the main surface 21 and the rear forming edge of the hole 22a. Therefore, with the insertion piece 32 inserted through the holes 22a of the first wall 20A and the second wall 20B, the front surfaces of the insertion piece 32 and the reinforcing piece 33 are in surface contact with the rear surface of the main surface 21, and the rear surface of the insertion piece 32 is in contact with the rear forming edge of the hole 22a. This restricts the relative movement of the first wall 20A and the second wall 20B in the front-to-back direction.

[0036] Next, the method for connecting the first wall 20A and the second wall 20B using the connector 30 will be described below with reference to Figures 3 to 7, as well as Figures 8 to 10. Figure 8 is a perspective view similar to Figure 3, showing the state immediately before inserting the insertion piece into the hole of each wall in the embodiment. Figure 9 is a perspective view similar to Figure 3, showing the state immediately after inserting the insertion piece into the hole of each wall in the embodiment. Figure 10 is a perspective view similar to Figure 3, showing the state in which the wall connection in the embodiment is completed.

[0037] First, as shown in Figure 3, the joint surfaces 22 of the first wall 20A and the second wall 20B are aligned in the front-to-back direction and arranged so that the joint surfaces 22 make surface contact with each other. As a result, the holes 22a of the first wall 20A and the second wall 20B are connected from left to right.

[0038] In this state, as shown in Figures 4 and 8, the front surfaces of the insertion piece 32 and reinforcing piece 33 of the connector 30 are in surface contact with the rear surface of the main surface 21 of the second wall 20B, and the vertical position of the connector 30 is aligned with respect to each hole 22a. Then, as also shown in Figure 7A, the connector 30 is approached from right to left (lateral direction) with respect to the holes 22a of the joining surface 22 of the second wall 20B. This approach involves sliding the insertion piece 32 and reinforcing piece 33 against the main surface 21, and sliding the connector 30 to the left (horizontally) so that the insertion piece 32 is inserted from the right side of each hole 22a.

[0039] As shown in Figures 5 and 7B, the sliding movement of the connector 30 is restricted by the surface contact (abutment) of the support piece 31 with the joint surface 22 of the second wall 20B, thereby positioning the connector 30 in the left-right direction. In this positioned state, the connector 30 is slid downward while maintaining surface contact between the joint surface 22 and the support piece 31. As a result, as shown in Figure 6, the notch 35 of the insertion piece 32 inserted into the hole 22a fits into the lower edge of the hole 22a, and the two joint surfaces 22 that are in surface contact with the notch 35 and the support piece 31 are sandwiched from the left-right direction. This restricts the relative displacement of each wall 20A, 20B in the left-right direction.

[0040] When the notch 35 fits into the formed edge of the hole 22a, the walls 20A and 20B are temporarily fixed by the connector 30, as shown in Figure 9. At this time, the vertical positions of the round hole 22b of the joint surface 22 and the round hole 31a of the support piece 31 (not shown in Figure 9, see Figure 8) are aligned and in communication. In this state, as shown in Figure 10, fastening members 38, such as bolts, are inserted through the round holes 22b and 31a and screwed into nuts or female threads (not shown). As a result, the two joint surface 22 and the support piece 31 are fastened from the left and right directions, and the connector 30 is attached to the walls 20A and 20B, connecting the walls 20A and 20B via the connector 30.

[0041] As described above, according to this embodiment, the process of changing from the state in Figure 3 to the state in Figure 8 is simply a matter of positioning the insertion piece 32 and the reinforcing piece 33 so that they are in surface contact with the main surface portion 21 of the second wall 20B. Furthermore, the process of changing from the state in Figure 8 to the state in Figure 9 is simply a matter of sliding the connector 30 to the left and downward so that the notch 35 of the insertion piece 32 fits into the hole 22a. Therefore, in this embodiment, the operation of connecting each wall 20A and 20B does not require any operating force that deforms the connector 30 or each wall 20A and 20B, thus preventing an increase in the workload.

[0042] Furthermore, in this connection process, the insertion piece 32 can be inserted into the hole 22a from the upper-lower intermediate portion of the joint surface 22, which is in the extending direction, and the notch 35 can be fitted with only a slight downward movement of the connector 30. This eliminates the need to provide space for the connector 30 to slide up and down at positions that protrude vertically from the upper or lower ends of the joint surface 22. Therefore, structural constraints such as shortening the vertical length of the joint surface 22 or changing the size of the housing 10 itself can be alleviated.

[0043] Furthermore, in the above embodiment, a hole 22a is formed at the boundary position between the joining surface portion 22 and the main surface portion 21, and the insertion piece portion 32 is inserted through this hole 22a. Therefore, when the connector 30 is installed, the insertion piece portion 32 is in surface contact with the rear surface of the main surface portion 21 of the first wall body 20A, and the reinforcing piece portion 33 is in surface contact with the rear surface of the main surface portion 21 of the second wall body 20B, on the joining surface portion 22 side which forms the connecting portion of each wall body 20A, 20B. As a result, the rigidity of the connecting portion of each wall body 20A, 20B can be increased by the connector 30, and deformation of the connecting portion can be effectively prevented.

[0044] Furthermore, the support piece 31, which is oriented in a direction intersecting the insertion piece 32 and the reinforcing piece 33, can reinforce the insertion piece 32 and the reinforcing piece 33 to suppress deflection deformation, thereby further increasing the rigidity at the connecting portion of each wall body 20A, 20B.

[0045] Furthermore, since the connector 30 has a length that extends almost the entire length of the joint surface 22 in the vertical direction, it is possible to secure a wide area in the vertical direction for connecting and reinforcing each wall body 20A, 20B with the connector 30. This increases the rigidity of the connecting portion of each wall body 20A, 20B and allows for better maintenance of the connection strength of each wall body 20A, 20B.

[0046] It should be noted that the present invention is not limited to the embodiments described above, and can be implemented with various modifications. In the embodiments described above, the size, shape, orientation, etc., shown in the accompanying drawings are not limited thereto, and can be appropriately modified within the scope that allows the present invention to exert its effects. Furthermore, it can be implemented with appropriate modifications as long as it does not deviate from the scope of the objectives of the present invention.

[0047] In the above embodiment, a single connector 30 is provided along substantially the entire length of the joint surface 22 in the vertical direction, but the invention is not limited to this configuration.

[0048] For example, the vertical length of the connector 30 may be made shorter than that of the joining surface portion 22, and separate connectors 30 may be provided at separate locations on both ends of the joining surface portion 22 in the vertical direction (the direction in which the joining surface portion 22 extends).

[0049] Another example is the modified configuration shown in Figure 11. Figure 11 is a perspective view similar to Figure 10, showing the completed connection of the wall bodies in the modified configuration. In the modified configuration of Figure 11, two connectors 30 are provided, and the two connectors 30 are arranged adjacent to each other in the vertical direction. In other words, the modified configuration is configured to divide the connector 30 of the above embodiment into two parts, vertically. Therefore, in the modified configuration, the connectors 30 are provided over substantially the entire vertical length of the joint surface 22 by the two connectors 30, and this also increases the rigidity of the connection portion of each wall body 20A, 20B. Fastening members 38 are provided on both the upper and lower sides of each of the two connectors 30 and fastened to the joint surface 22.

[0050] Thus, the vertical length, mounting position, and number of connectors 30 are not particularly limited and can be arbitrarily changed according to various conditions such as the size, dimensions, weight, and thickness of each wall 20A and 20B, as well as the intended use of the housing 10.

[0051] Furthermore, in the case of the connector 30, the number of insertion pieces 32 may be one or more than three instead of three, and the number of reinforcing pieces 33 may be one or more than four instead of four. Here, when there are multiple insertion pieces 32, the insertion pieces 32 may be provided at equal intervals in the extending direction of the joint surface 22, or the spacing of the insertion pieces 32 in the part that increases the connection strength from the viewpoint of vibration suppression, etc., may be narrower than in the other parts.

[0052] Furthermore, the angle between the main surface portion 21 and the joining surface portion 22 may be an acute angle instead of a right angle. In this case, in the connector 30, the angle between the support piece portion 31 and the insertion piece portion 32 will be other than a right angle, and the angle of the reinforcing piece portion 33 will also be changed according to the angles of the main surface portion 21 and the joining surface portion 22.

[0053] Furthermore, in the case of the connector 30, the support piece 31 may be omitted, and an insertion piece 32 may be arranged to straddle the two joining surfaces 22, with a notch 35 formed in the insertion piece 32 at a position corresponding to the hole 22a to sandwich the joining surfaces 22. Moreover, in the case of the connector 30, a part or all of the reinforcing piece 33 may be omitted. However, forming the support piece 31 and the reinforcing piece 33 as in the above embodiment makes it possible to better demonstrate the connecting strength of each wall body 20A, 20B.

[0054] Furthermore, in the case of the hole 22a, the formation position on each wall body 20A, 20B may be changed, for example, by forming it in the center of the front-to-back direction of the joint surface 22, as long as it can be fitted into the notch 35 and the two joining surface portions 22 can be sandwiched by the insertion piece 32.

[0055] Furthermore, the shape of the main surface portion 21 only needs to form the outer circumferential surface of the housing 10, and in addition to being formed flat, it may also be a curved shape along an arc or a bent shape.

[0056] Furthermore, the wall bodies connected by the connector 30 can be adjacent wall bodies, and may include the side wall body 20 and the upper wall body 11 or the lower wall body 12. In this case, the angle between the main surface portion 21 and the joint surface portion 22 may become acute, or the main surface portion 21 may take on a bent shape.

[0057] Furthermore, although the above embodiment describes a configuration in which the connector 30 is provided inside the housing 10, it may also be provided outside the housing 10. In this configuration, the joint surface portion 22 has its tip facing outward (forward) from the housing 10. [Explanation of symbols]
