Description

[Technical Field]

[0001] This invention relates to a wiring harness box and a wiring harness device. Specifically, this invention relates to a wiring harness box and a wiring harness device having an openable and closable cover. [Previous Technology]

[0002] Document 1 (Japanese Patent Publication No. 2018-174114) discloses a wiring device box having a cover body covering the wiring device. The wiring device box of Document 1 includes: a housing for holding the wiring device, a cover body, and a shaft for connecting the housing and the cover body.

[0003] The cover body is mounted on the housing in a rotatable state, between a position covering the wiring device and a position exposing the wiring device. The cover body has a bearing portion with a bearing cavity into which the shaft can be inserted, and a hook portion is provided on the outer peripheral surface of the bearing portion. The housing has a limiting protrusion located on the trajectory of the hook portion when the cover body moves from the closed position to the open position. When the cover body is in the closed position, the wiring device is covered by the cover body. When the cover body is moved from the closed position to the open position, the hook portion extends beyond the limiting protrusion. When the cover body is in the open position, the movement of the cover body towards the closed position is restricted by the contact between the limiting protrusion and the hook portion, thereby exposing the wiring device. [Summary of the Invention]

[0006] One aspect of the wiring device of the present invention includes: a wiring device housing and a wiring device held by the housing.

Implementation Method

[0008] Hereinafter, the wiring harness box and wiring harness device of the embodiments will be described in detail with reference to the drawings. However, the dimensional ratios of the components in the schematic diagrams of the following embodiments are not necessarily required to reflect the actual dimensional ratios. Furthermore, the configurations described in the following embodiments are merely examples of the present invention. The present invention is not limited to the following embodiments, and various modifications can be made according to the design, etc., as long as the effects of the present invention can be achieved.

[0009] (Embodiment) (1) Schematic diagram 1 is an exploded perspective view of the wiring device 1 of the wiring device box 2 of this embodiment.

[0010] The wiring device box 2 of this embodiment includes: a housing 10, a cover 20 and a middle frame 30.

[0011] The housing 10 can hold the wiring device 60 and can be installed on the construction surface 100.

[0012] The cover 20 is supported in a rotatable manner relative to the housing 10 between a closed position that covers the wiring device 60 held by the housing 10 and an open position that exposes the wiring device 60 held by the housing 10.

[0013] The middle frame 30 has a plate-shaped portion 31 with a window 32 that exposes the wiring device 60 held by the housing 10, and is disposed on the opposite side of the construction surface 100 to the housing 10.

[0014] The housing 10 has a wall portion 14 facing the periphery of the plate-shaped portion 31. A first fitting portion is provided in the wall portion 14 at the location facing the plate-shaped portion 31. A mounting piece 33A is provided at the periphery of the plate-shaped portion 31, protruding from the plate-shaped portion 31 along the normal direction of the plate-shaped portion 31. A second fitting portion is provided on the mounting piece 33A, which can fit into the first fitting portion. The position of the second fitting portion is offset from the position of the plate-shaped portion 31 along the normal direction of the plate-shaped portion 31.

[0015] Here, in this embodiment, for example, the first fitting portion of the housing 10 is a fitting protrusion 19 provided in the wall portion 14 facing the plate-shaped portion 31, and the second fitting portion of the middle frame 30 is provided in the recess 34 of the mounting piece 33A (refer to FIG. 9). The fitting protrusion 19 provided in the wall portion 14 of the housing 10 fits into the recess 34 of the mounting piece 33A, thereby mounting the middle frame 30 onto the housing 10.

[0016] Here, in the normal direction of the plate-shaped portion 31, the position of the second fitting portion is offset from the position of the plate-shaped portion 31. If the two surfaces in opposite directions in the normal direction (i.e., the thickness direction) of the plate-shaped portion 31 are designated as the first surface 31A and the second surface 31B, then the position of the second surface 31B when the middle frame 30 is installed on the housing 10 with the first surface 31A facing the construction surface 100 is offset from the position of the first surface 31A when the middle frame 30 is installed on the housing 10 with the second surface 31B facing the construction surface 100, in the normal direction. Therefore, when there are two types of wiring harnesses 60 with different distances from the mounting frame 70 to the front of the wiring harness 60 while the wiring harness 60 is held by the mounting frame 70, the inner and outer surfaces of the middle frame 30 can be replaced to fit the size of the wiring harness 60 and installed on the housing 10. Therefore, the wiring fixture box 2 of this embodiment can accommodate two different sizes of wiring fixtures 60, thereby reducing the number of items in the wiring fixture box 2.

[0017] Furthermore, the wiring device 1 of this embodiment includes: a wiring device box 2 and a wiring device 60 held by the housing 10.

[0018] Since the wiring device 1 is equipped with the wiring device box 2, it can install two different sizes of wiring devices 60, thereby reducing the number of items in the wiring device box 2.

[0019] Furthermore, the wiring device box 2 of this embodiment, in addition to the aforementioned housing 10 and cover 20, also includes a rotating shaft 40 and a leaf spring portion 51.

[0020] The rotating shaft 40 is fixed to the housing 10 in a rotatable state. The rotating shaft 40 has a polygonal cylindrical shaft portion 41 with a cross-section orthogonal to the axial direction.

[0021] The housing 10 is provided with a shaft insertion hole 11 for inserting the polygonal cylindrical shaft portion 41 of the rotating shaft 40 into a rotatable state.

[0022] The cover 20 has a shaft hole 25 into which a portion of the rotating shaft 40 can be inserted. The cover 20, by rotating together with the rotating shaft 40 inserted into the shaft hole 25, can rotate relative to the housing 10 between a closed position that covers the wiring device 60 held by the housing 10 and an open position that exposes the wiring device 60 held by the housing 10.

[0023] The leaf spring portion 51 can contact the polygonal cylindrical shaft portion 41 that is inserted into the shaft insertion hole 11.

[0024] The cover 20 can hold the rotational position of the leaf spring portion 51 when it makes face contact with at least one of the plurality of faces 42 of the polygonal column shaft portion 41.

[0025] Here, by inserting the polygonal cylindrical shaft portion 41 of the rotating shaft 40 into the shaft insertion hole 11 of the housing 10 in a rotatable state, the rotating shaft 40 is fixed in a state in which it can rotate relative to the housing 10.

[0026] The cover 20 is provided with a shaft hole 25 into which a portion of the rotating shaft 40 can be inserted. The cover 20 and the rotating shaft 40 inserted into the shaft hole 25 rotate together, thereby allowing the cover 20 to rotate between a closed position and an open position. Furthermore, the leaf spring portion 51 is disposed in the shaft insertion hole 11 into which the polygonal column shaft portion 41 can be inserted. By the leaf spring portion 51 making surface contact with at least one surface 42 of the polygonal column shaft portion 41, the rotation of the polygonal column shaft portion 41 is stopped, thus securing the cover 20 in that position. Here, since the polygonal column shaft portion 41 and the leaf spring portion 51 are disposed inside the shaft insertion hole 11, even if the polygonal column shaft portion 41 wears and generates wear dust, the wear dust is unlikely to adhere to the surface of the cover 20, thereby reducing the possibility of wear dust adhering to the surface of the cover 20.

[0027] (2) Details are as follows: the wiring device box 2 and the wiring device device 1 of this embodiment will be described in detail with reference to the drawings.

[0028] In this embodiment, the "construction surface" is the surface on which the wiring device 60 can be installed, for example, the surface of the exterior wall of a building.

[0029] Figure 6 is a front view of the wiring device 1 installed on the construction surface 100 (e.g., the exterior wall of a building) after the cover 20 has been removed. Furthermore, in the following description, the X-axis direction in Figure 1, etc., is defined as the left-right direction, the Y-axis direction as the front-back direction (depth direction), and the Z-axis direction as the up-down direction. Moreover, the positive direction of the X-axis is set to the right, the positive direction of the Y-axis is set to the front, and the positive direction of the Z-axis is set to the top. However, these directions are merely examples and are not intended to limit the orientation of the wiring device box 2 and the wiring device 1 during use. Also, the arrows showing each direction in the figures are for illustrative purposes only and do not represent actual objects.

[0030] (2.1) As described above, the wiring device 1 includes: a wiring device box 2 and a wiring device 60. In this embodiment, the wiring device 1 further includes: a mounting frame 70, an insulating cover 80 and a waterproof gasket 90.

[0031] Hereinafter, the wiring device box 2, wiring device 60, mounting frame 70, insulating cover 80 and waterproof gasket 90 of the wiring device device 1 will be described with reference to Figures 1 to 14.

[0032] (2.1.1) Wiring fixture and mounting frame The wiring fixture 60 is, for example, a power socket. The wiring fixture 60 is installed with its rear part embedded in a recessed hole 101 (see FIG. 12) provided in the construction surface (e.g., the surface of the wall material) 100 using a mounting frame 70 for recessed wiring fixtures. The mounting frame 70 is integrally mounted to the wiring fixture 60 of this embodiment.

[0033] The wiring device 60 has a rectangular parallelepiped body 61. The body 61 is formed by combining a rear housing 62 and a front cover 63 (see Figure 12). On the front of the body 61 (i.e., the front of the cover 63), there are two plug insertion ports 64 for connecting electrical appliances. When the wiring device 60 is installed on the construction surface 100 and the power cord from an AC power source such as a commercial power supply is connected to the wiring device 60, when the plug of an electrical appliance is connected to the plug insertion port 64, power is supplied from the wiring device 60 to the electrical appliance.

[0034] The wiring device 1 further includes a mounting frame 70 that can be installed on the construction surface 100 while the wiring device 60 is held in place. The phrase "the mounting frame 70 can be installed on the construction surface 100" can include "the mounting frame 70 being directly installed on the construction surface 100" and "the mounting frame 70 being installed on the construction surface 100 via other components." In this embodiment, for example, an insulating cover 80 is disposed between the mounting frame 70 and the construction surface 100, and the mounting frame 70 is installed on the construction surface 100 via the insulating cover 80.

[0035] The mounting frame 70 is formed into a rectangular frame shape with an opening 71 for mounting the wiring device 60, for example, by means of a metal material (refer to Figures 12 and 13). The mounting frame 70 is installed on the construction surface 100 with its long side parallel to the vertical direction. The mounting frame 70 has a pair of horizontal pieces 72 facing each other with the opening 71 sandwiched in the long side direction, and a pair of vertical pieces 73 facing each other with the opening 71 sandwiched in the short side direction. The upper ends of the pair of vertical pieces 73 are connected by the upper horizontal pieces 72, and the lower ends of the pair of vertical pieces 73 are connected by the lower horizontal pieces 72. That is, the pair of horizontal pieces 72 and the pair of vertical pieces 73 form a rectangular frame shape, and the space enclosed by the pair of horizontal pieces 72 and the pair of vertical pieces 73 is the opening 71.

[0036] Each of the pair of longitudinal plates 73 has two U-shaped slits 74 that can be inserted into protrusions respectively provided on the sides of the housing 62 and the cover 63. When the housing 62 and the cover 63 are joined, with the cover 63 overlapping the front side of the housing 62, the housing 62 and the cover 63 are inserted into the opening 71 from the rear side of the mounting frame 70. Then, with the protrusions on the sides of the housing 62 and the cover 63 inserted into the slits 74, the rear part of the slits 74 is deformed, and the housing 62 and the cover 63 are joined by the mounting frame 70, so that the wiring device 60 is mounted on the mounting frame 70.

[0037] With a portion of the back side of each of the pair of transverse plates 72 facing the construction surface 100 (specifically, the periphery of the embedded hole 101 in the construction surface 100), an insertion hole 75 is provided at a position that does not overlap with the periphery of the embedded hole 101. The insertion hole 75 is elliptical in shape with the left-right direction as its major axis. A screw for locking the mounting frame 70 to a fixing member disposed on the inner side of the construction surface 100 is inserted into the insertion hole 75. Examples of fixing members include a wiring box embedded on the inner side of the construction surface 100, a C-shaped clamp disposed on the inner side of the construction surface, etc.

[0038] Furthermore, each of the pair of transverse pieces 72 has an L-shaped hole 76 on the left and right sides of the insertion hole 75 for mounting the clamping member.

[0039] Furthermore, each of the pair of horizontal plates 72 is provided with a screw hole 77 for locking a screw into the housing 10 of the wiring device box 2. That is, a mounting frame 70 for wiring devices can be installed on the housing 10, and a pair of screw holes 77 are provided on both sides of the opening 71 where the wiring device 60 is disposed on the mounting frame 70.

[0040] (2.1.2) The wiring device 1 of this embodiment further includes an insulating cover 80 disposed between the mounting frame 70 and the working surface 100.

[0041] The insulating cover 80 is installed between the mounting frame 70 and the construction surface 100 to provide electrical insulation between the metal mounting frame 70 and the construction surface 100.

[0042] The insulating cover 80 is formed into a rectangular frame shape with a window 81 into which the wiring device 60 can be inserted, by means of, for example, a synthetic resin material (see Figures 1 and 12).

[0043] An insulating cover 80 is installed on the construction surface 100 with its long side parallel to the vertical direction. The insulating cover 80 has: a pair of horizontal pieces 82 facing each other with the window opening 81 sandwiched in the long side direction, and a pair of vertical pieces 83 facing each other with the window opening 81 sandwiched in the short side direction. The upper ends of the pair of vertical pieces 83 are connected by the upper horizontal pieces 82, and the lower ends of the pair of vertical pieces 83 are connected by the lower horizontal pieces 82. That is, the pair of horizontal pieces 82 and the pair of vertical pieces 83 form a rectangular frame, and the space enclosed by the pair of horizontal pieces 82 and the pair of vertical pieces 83 is the window opening 81.

[0044] A pair of horizontal pieces 82 are configured to overlap with the rear side of a pair of horizontal pieces 72 of the mounting frame 70.

[0045] Each of the pair of horizontal plates 82 has an elliptical through hole 84 at a position corresponding to the insertion hole 75 of the mounting frame 70, which is connected to the insertion hole 75. Each of the pair of horizontal plates 82 has a rib 88 protruding forward from the periphery of the through hole 84. The rib 88 seen from the front is elliptical in shape, and when the insulating cover 80 is installed behind the mounting frame 70, the rib 88 is inserted into the insertion hole 75 of the mounting frame 70.

[0046] Furthermore, each of the pair of horizontal pieces 82 is provided with two snap-fit ​​parts 85. Each of these two snap-fit ​​parts 85 is snap-fitted into two holes 76 respectively provided on the pair of horizontal pieces 72. The two snap-fit ​​parts 85 provided on the horizontal pieces 82 are arranged on the left and right sides with the through hole 84 as the center. The snap-fit ​​parts 85 protrude forward from the horizontal piece 82 and have a plate-shaped part 86 at the front end that can move in the left and right direction. At the front end of the plate-shaped part 86, there is a claw 87 protruding toward the through hole 84.

[0047] When the insulating cover 80 is brought closer from the rear of the mounting frame 70 to insert the wiring device 60, which is held by the mounting frame 70, into the window hole 81, the rib 88 is inserted into the insertion hole 75, and at the same time, the plate-shaped portion 86 of the snap-fit ​​engagement part 85 is inserted into the hole 76. At this time, the rib 88 contacts the end face of the insertion hole 75, thereby positioning the insulating cover 80 with the mounting frame 70. Furthermore, when the plate-shaped portion 86 is inserted into the hole 76, the claw 87 at the front end of the plate-shaped portion 86 presses against the end face of the hole 76, thereby causing the plate-shaped portion 86 to elastically deform. Next, when the plate-shaped portion 86 is further inserted into the hole 76 and the claw 87 passes through the end face of the hole 76, the plate-shaped portion 86 returns to its state before elastic deformation. By hooking the front of the cross piece 72 with the claw 87, the snap-fit ​​engagement part 85 is prevented from loosening, and the insulating cover 80 is installed on the mounting frame 70.

[0048] Furthermore, with the insulating cover 80 mounted on the mounting frame 70, pushing the two snap-fit ​​portions 85 (plate-shaped portions 86) respectively provided on the pair of cross plates 82 in a direction that widens the distance between them will cause the claws 87 to disengage from the periphery of the hole 76. With the claws 87 disengaged from the periphery of the hole 76, when the insulating cover 80 is moved away from the mounting frame 70 (rearward), the plate-shaped portions 86 will protrude outside the hole 76, and the snap-fit ​​portions 85 will disengage from the hole 76. In this way, the insulating cover 80 can be removed from the mounting frame 70.

[0049] As described above, the insulating cover 80 is provided with a snap-fit ​​part 85 that can be attached to and detached from the hole 76 provided in the mounting frame 70. Therefore, the insulating cover 80 can be installed and removed from the mounting frame 70 without the need for fastening components such as screws or special tools.

[0050] When the insulating cover 80 is sandwiched between the mounting frame 70 and the construction surface 100, and the mounting frame 70 is installed on the construction surface 100, the pair of transverse pieces 82 of the insulating cover 80 contact the periphery of the embedded hole 101 in the construction surface 100. Therefore, the mounting frame 70 is installed on the construction surface 100 while being electrically insulated from the construction surface 100 by the insulating cover 80.

[0051] (2.1.3) Wiring fixture box The wiring fixture box 2 includes: a housing 10, a cover 20 and a rotating shaft 40. Furthermore, the wiring fixture box 2 also includes: a spring member 50, a spring holding member 56 and a middle frame 30.

[0052] <Shell> Shell 10 is a molded article made of, for example, synthetic resin material.

[0053] A mounting frame 70 for holding the wiring device 60 can be installed on the housing 10. In other words, the housing 10 is fixed to the construction surface 100 by mounting the housing 10 on the mounting frame 70 fixed to the construction surface 100. That is, the housing 10 can be installed on the construction surface 100. Here, "the housing 10 can be installed on the construction surface 100" can mean that the housing 10 is directly installed on the construction surface 100, or that the housing 10 is installed on the construction surface 100 via other components. In this embodiment, the housing 10 is installed on the construction surface 100 via, for example, the mounting frame 70 and the insulating cover 80.

[0054] The housing 10 has a frame portion 13 with a rectangular through hole 12 into which a wiring device 60 held by the mounting frame 70 can be inserted. In other words, the housing 10 has a through hole 12 into which a wiring device 60 held by the mounting frame 70 can be inserted.

[0055] At one end (e.g., the upper end) along the long side of the frame portion 13, a semi-cylindrical first bearing portion 111 with openings on both sides and the rear side in the left-right direction is provided. The first bearing portion 111 is located in the central part in the left-right direction of the upper end of the frame portion 13. In this embodiment, since the polygonal cylindrical shaft portion 41 of the rotating shaft 40 is inserted into the first bearing portion 111 from the left and right sides, the left and right openings of the first bearing portion 111 become shaft insertion holes 11.

[0056] A spring member 50 having the above-mentioned leaf spring portion 51 is disposed on the inner side of the first bearing portion 111. Specifically, a spring member 50 and a spring holding member 56 for holding the spring member 50 are disposed on the inner side of the first bearing portion 111 (refer to Figures 3 and 5).

[0057] Furthermore, a wall portion 14 protruding forward from the periphery of the through hole 12 is provided in the frame portion 13 of the housing 10.

[0058] On two of the four inner sides of the wall portion 14 that face each other in the vertical direction, there is a mounting plate 15 that is an isosceles trapezoid in shape when viewed from above. The mounting plate 15 has a through hole 150 for screws that are locked into the screw holes 77 of the mounting frame 70 to pass through. That is, the housing 10 has a pair of through holes 150 through which a pair of screws that are locked into the screw holes 77 of the mounting frame 70 can be inserted.

[0059] Here, in the mounting frame 70, corresponding to the size difference of the wiring device 60 mounted on the mounting frame 70, there are a first mounting frame and a second mounting frame with different spacing between a pair of screw holes 77. For example, the mounting frame 70 with a first spacing between a pair of screw holes 77 is called the first mounting frame, and the mounting frame 70 with a second spacing between a pair of screw holes 77 that is shorter than the first spacing is called the second mounting frame. The housing 10 of this embodiment is configured to be mounted in either the first mounting frame or the second mounting frame.

[0060] Specifically, the shape of each of the pair of through holes 150 is the shape formed by connecting the first through hole 151 and the second through hole 152 (refer to Figures 13 and 14). The first through hole 151 is a hole into which a screw that is locked into the pair of screw holes 77 can be inserted when the interval between the pair of screw holes 77 is a first interval W1. The second through hole 152 is a hole into which a screw that is locked into the pair of screw holes 77 can be inserted when the interval between the pair of screw holes 77 is a second interval W2. Here, on the inner side of each of the pair of through holes 150, near the boundary between the first through hole 151 and the second through hole 152, there is a protrusion 153 that protrudes inward. Therefore, when a screw is inserted into the first through hole 151, it has the advantage that the screw inserted into the first through hole 151 abuts against the protrusion 153, making it difficult to move towards the second through hole 152. Similarly, when the screw is inserted into the second through hole 152, it has the advantage that the screw inserted into the second through hole 152 abuts against the protrusion 153, making it difficult to move towards the first through hole 151. Furthermore, it is not necessary to provide the protrusion 153 on the inner surface of each of the pair of through holes 150, and the shape of each of the pair of through holes 150 can also be an elliptical shape formed by connecting the first through hole 151 and the second through hole 152.

[0061] Furthermore, on the two inner sides facing each other in the left-right direction among the four inner sides of the wall portion 14, each is provided with three sets of protrusions 16 extending in the front-back direction, separated by a predetermined interval in the up-down direction. The three sets of protrusions 16 are each provided on the upper, middle and lower parts of the inner side.

[0062] Furthermore, in each of the two sets of protrusions 16 located on the upper and lower parts of the inner side, a dome-shaped fitting protrusion 19 is provided between the two protrusions 16 in each set. Here, the fitting protrusion 19 becomes a second fitting part that fits into the recess 34 of the plate-shaped portion 31 of the middle frame 30. Also, the second fitting part, i.e., the fitting protrusion 19, is located between the two protrusions 16. That is, in the wall portion 14 of the housing 10, at the portion facing the plate-shaped portion 31 of the middle frame 30, a protrusion 16 is provided in a manner parallel to the first fitting part, i.e., the fitting protrusion 19. In other words, in the wall portion 14 of the housing 10, at the portion facing the plate-shaped portion 31, a protrusion 16 is provided in a manner parallel to the first fitting part (e.g., the fitting protrusion 19 in this embodiment).

[0063] Furthermore, the housing 10 is provided with a limiting protrusion 18 that protrudes from the rear end of the inner surface of the wall portion 14 (or the inner surface of the through hole 12) toward the center of the through hole 12.

[0064] Furthermore, at the lower right corner of the wall portion 14, a plate-shaped hook portion 17 is provided, protruding upward from the front end of the inner side of the lower side of the wall portion 14. When the cover 20 is in the closed position, and the locking member 95 rotates to the locked position where the locking piece 98 protrudes downward from the shaft portion 96, the hook portion 17 is positioned to overlap with at least a portion of the locking piece 98 in the front-rear direction. Furthermore, when the cover 20 is in the closed position, and the locking member 95 rotates to the unlocked position where the locking piece 98 protrudes to the left from the shaft portion 96, the cover 20 can be moved from the closed position to the open position because the locking piece 98 moves to a position where the entire locking piece 98 does not overlap with the locking piece 98 in the front-rear direction.

[0065] <Rotation Shaft> The rotation shaft 40 is, for example, a resin molded article. In this embodiment, the wiring device box 2 has two rotation shafts 40, and the cover 20 is rotatably supported on the housing 10 through the two rotation shafts 40.

[0066] The two rotating shafts 40 are, for example, molded articles made of synthetic resin. Furthermore, the two rotating shafts 40 have the same shape.

[0067] The rotating shaft 40 has a cylindrical shaft body 43 (refer to FIG. 4). At the first end of the shaft body 43 in the direction of rotation axis, there is a large-diameter portion 46 in the shape of a disk with a diameter larger than that of the shaft body 43. At the second end of the shaft body 43 in the direction of rotation axis, there is a polygonal prism shaft portion 41 with a cross-sectional shape orthogonal to the axial direction. The cross-sectional shape of the polygonal prism shaft portion 41 is, for example, a regular hexagon, but it can be a square or a regular octagon.

[0068] Furthermore, a groove 45 extending in the circumferential direction is formed on the surface of the shaft body 43 of the rotating shaft 40, covering the entire circumference of the shaft body 43. Also, a raised portion 44 extending from the large diameter portion 46 to the middle of the shaft body 43 is provided on the surface of the shaft body 43 along the axial direction of the shaft body 43. Furthermore, when the wiring harness housing 2 is assembled, the raised portion 44 is positioned from the large diameter portion 46 to the position contacting the spring holding member 56.

[0069] <Spring Member and Spring Holding Member> The spring member 50 is formed by bending sheet metal of metal such as stainless steel. In this embodiment, since the left and right openings of the first bearing portion 111 allow the insertion of rotating shafts 40, two leaf spring portions 51 are disposed inside the first bearing portion 111, each contacting the polygonal column shaft portions 41 of the two rotating shafts 40 inserted from the left and right openings (shaft insertion holes 11) of the first bearing portion 111. In this embodiment, the spring member 50 disposed inside the first bearing portion 111 has two leaf spring portions 51.

[0070] As shown in Figures 4 and 5, the leaf spring portion 51 has a pair of flat plates 52 facing each other and a curved surface portion 53 connecting the ends of the pair of flat plates 52 to each other. Viewed from the axial direction of the rotation axis 40, the leaf spring portion 51, including the pair of flat plates 52 and the curved surface portion 53, has a U-shaped shape. The leaf spring portion 51 is arranged such that the normal directions of the pair of flat plates 52 are parallel to the vertical direction. Furthermore, the leaf spring portion 51 is arranged such that the pair of flat plates 52 clamp the polygonal column shaft portion 41 from both sides. Also, the curved surface portion 53 is arranged such that it is located on the opposite side of the construction surface 100 from the pair of flat plates 52. Thus, the curved surface portion 53 connects the front ends of the pair of flat plates 52 to each other, and the curved surface portion 53 is curved such that the middle portion of the curved surface portion 53 protrudes further forward than the two ends of the curved surface portion 53.

[0071] Furthermore, the spring member 50 includes: a connecting piece 54A that connects the upper flat plate portions 52 of the two leaf spring portions 51; and a connecting piece 54B that connects the lower flat plate portions 52 of the two leaf spring portions 51. Two rearwardly protruding retaining springs 55 are provided at the rear ends of each of the connecting pieces 54A and 54B. The two retaining springs 55 provided on the upper connecting piece 54A and the two retaining springs 55 provided on the lower connecting piece 54B are aligned vertically. The front ends of the two retaining springs 55 provided on the upper connecting piece 54A and the front ends of the two retaining springs 55 provided on the lower connecting piece 54B are bent into a mountain shape and protrude towards each other.

[0072] The spring retaining member 56 is, for example, a molded article of synthetic resin. The spring retaining member 56 is disposed inside the first bearing portion 111 of the housing 10 in the state of retaining the spring member 50.

[0073] The spring holding member 56 has a base 57 that is long in the left-right direction and has a cuboid shape.

[0074] On the top surface of the base 57, there are two mounting grooves 573 for inserting two retaining springs 55, each of which is inserted into the connecting piece 54A disposed on the upper side of the spring member 50. Although the figure is omitted, on the bottom surface of the base 57, there are also two mounting grooves 573 for inserting two retaining springs 55, each of which is inserted into the connecting piece 54B disposed on the lower side of the spring member 50.

[0075] A recess 574 for inserting a spring member 50 is provided on the front side of the base 57. A pivot support 58 is provided on the base 57 with round holes for inserting a rotating shaft 40 on the left and right sides of the recess 574. Furthermore, a shaft stop 571 is provided at the right end of the base 57 to prevent the rotating shaft 40 inserted into the pivot support 58 on the right side of the base 57 from becoming loose. A shaft stop 571 is provided at the left end of the base 57 to prevent the rotating shaft 40 inserted into the pivot support 58 on the left side of the base 57 from becoming loose.

[0076] In this embodiment, the rotating shaft 40 is rotatably supported on the spring holding member 56 by passing the rotating shaft 40 through the circular hole of the pivot support portion 58 of the spring holding member 56, and the rotating shaft 40 is rotatably supported on the housing 10 by installing the spring holding member 56. Furthermore, the rotating shaft 40 stops at a position where the two surfaces 42 of the polygonal prism shaft portion 41 of the rotating shaft 40 make surface contact with a pair of flat plates 52 of the leaf spring portion 51 of the spring member 50, thus securing the cover 20 at the stopped position of the rotating shaft 40. Also, in this embodiment, the rotating shaft 40 is rotatably supported on the spring holding member 56 by passing the rotating shaft 40 through the circular hole of the pivot support portion 58, but it is also possible to rotatably support the rotating shaft 40 by clamping it between the spring holding member 56 and the spring member 50 held by the spring holding member 56.

[0077] The shaft stopping part 571 is formed in the shape of a fork with a pair of clamping pieces 572 that clamp the rotating shaft 40 from the upper and lower sides. On the opposite side of the pair of clamping pieces 572, there are claws that can be inserted into the grooves 45 of the rotating shaft 40.

[0078] Furthermore, at the left and right ends of the base 57, there are protrusions 575 that are cantilevered and supported on the base 57 and whose front ends can be bent in the left and right directions. On the inner side of the housing 10 facing the internal space of the first bearing portion 111, there are recesses that can fit into the protrusions 575.

[0079] <Lid> The lid 20 is a molded article made of synthetic resin (refer to Figures 1-4). The lid 20 includes: a front wall 21, which is a longitudinally elongated rectangle when viewed from the front; a lower wall 23, which protrudes rearward from the lower end of the front wall 21; an upper wall 24, which protrudes obliquely upward and backward from the upper end of the front wall 21; and left and right side walls 22, which each protrude rearward from the right and left ends of the front wall 21. The lid 20 is formed into a box shape with a rear opening by the front wall 21, lower wall 23, upper wall 24, and left and right side walls 22.

[0080] At the upper end of the upper wall 24, a recess 242 is provided for inserting the first bearing portion 111 of the housing 10 into the central portion in the left-right direction. At the upper end of the upper wall 24, a pair of second bearing portions 241 are provided on both sides of the recess 242. Each pair of second bearing portions 241 is provided with a shaft hole 25 into which a rotating shaft 40 can be inserted. The central axis of each pair of shaft holes 25 in the pair of second bearing portions 241 is aligned when viewed from the left-right direction. Each pair of shaft holes 25 is provided with a keyway 251 into which a protrusion 44 of the rotating shaft 40 can be inserted (see Figure 4).

[0081] A recess 27 for threading is provided in the center of the lower wall 23 in the left-right direction. The recess is recessed into a rectangle from the rear end edge of the lower wall 23.

[0082] A circular hole 26 is provided on the lower right part of the surface of the front wall 21 (refer to Figure 2). A cylindrical hub 28 with a through hole continuous with the circular hole 26 is provided on the back side of the front wall 21.

[0083] A locking member 95 is configured in a rotatable state in the round hole 26 of the cover 20.

[0084] The locking member 95 has: a cylindrical shaft portion 96 and a disc-shaped operating portion 97 provided at a first end in the axial direction of the shaft portion 96. A rectangular plate-shaped locking piece 98 is installed at a second end in the axial direction of the shaft portion 96.

[0085] The locking member 95, with the shaft portion 96 at the front, is inserted into the circular hole 26 of the cover 20. When the operating part 97 is inserted into the circular hole 26 and the shaft portion 96 is inserted into the hub 28, the front end of the shaft portion 96 protrudes from the rear end of the hub 28. A locking piece 98 is installed on the front end of the shaft portion 96 that protrudes from the rear end of the hub 28. Thus, the locking member 95 has an operating part 97 protruding to the outside of the cover 20, and is held in a rotatable state relative to the cover 20 with the operating part 97 protruding to the outside of the cover 20. The locking piece 98 protrudes from the locking member 95 (specifically, the second end of the shaft portion 96) in a direction intersecting the direction along the rotation center of the locking member 95, i.e., the central axis (the direction of the central axis of the shaft portion 96). By rotating together with the locking member 95, the locking piece 98 can move between a locked position that engages with the hook portion 17 of the housing 10 and an unlocked position that disengages from the hook portion 17.

[0086] When the cover 20 is moved to the closed position covering the wiring device 60 (that is, the rear ends of the side wall 22 and lower wall 23 of the cover 20 are in contact with the front of the housing 10), when the locking member 95 is rotated, the locking piece 98 moves from the shaft portion 96 to the downward protruding locking position, and the hook portion 17 overlaps with the locking piece 98 in the front-rear direction. In this state, when it is desired to rotate the cover 20 from the closed position to the open position, the locking piece 98 abuts against the hook portion 17 and prevents the cover 20 from rotating, thus fixing the cover 20 in the closed position.

[0087] On the other hand, when the cover 20 is moved to the closed position and the locking piece 98 of the locking member 95 is moved to the locked position, if the locking member 95 is rotated 90 degrees clockwise, the locking piece 98 moves from the shaft portion 96 to the unlocked position protruding to the left. At this time, since the locking piece 98 moves to a position where it does not overlap with the hook portion 17 in the front-back direction, the cover 20 can be rotated from the closed position to the open position.

[0088] Here, the tool for rotating the locking member 95 includes a first tool T1 and a second tool T2 with different front end shapes. (Refer to FIG2). Therefore, the operating part 97 is provided with a first hole 99 into which the front end portion 200 of the first tool T1 can be inserted, and a second hole 94 into which the front end portion 210 of the second tool T2 can be inserted.

[0089] The first tool T1 is, for example, a flathead screwdriver, and the first hole 99 is a rectangular hole into which the front end portion 200 of the first tool T1 can be inserted. That is, the first hole 99 is a rectangular hole when viewed from above. The first hole 99 is provided along a line segment L1 (refer to FIG2) that passes through the center of the operating part 97 and is orthogonal to the central axis of the locking member 95.

[0090] The second tool T2 is a dedicated tool for the wiring device box 2. The second tool T2 has a rectangular plate-shaped flat plate portion 211. At both ends of the front end portion of the flat plate portion 211, there is a pair of rectangular protrusions 212. Here, the front end portion 210 of the second tool T2 includes one pair of protrusions 212 provided at the front end of the flat plate portion 211. Since the front end portion 210 of the second tool T2 includes a pair of protrusions 212, a pair of second holes 94 are provided in the operating portion 97, each of which can be inserted into one of the pair of protrusions 212.

[0091] The size of each of the pair of protrusions 212 is smaller than the front end portion 200 of the first tool T1. Therefore, the size of the second hole 94 in top view is smaller than the size of the first hole 99 in top view. Here, the pair of second holes 94 are provided along a line segment L2 (refer to FIG. 2) that passes through the center of the circular operating part 97 in top view and is orthogonal to the long side direction of the first hole 99 (the direction parallel to line segment L1). In other words, the two second holes 94 are provided side by side along a line segment L2 that passes through the center position in the long axis direction of the first hole 99 and is orthogonal to the long axis direction of the first hole 99.

[0092] Thus, the operating part 97 is provided with a first hole 99 into which the front end portion 200 of the first tool T1 can be inserted, and a second hole 94 into which the front end portion 210 of the second tool T2 can be inserted. Therefore, the locking member 95 can be rotated regardless of whether either the first tool T1 or the second tool T2 is used. Furthermore, when the shape of the operating part 97 is circular when viewed from above, the second hole 94 is provided at the part of the operating part 97 where the width is greatest in the direction orthogonal to the long axis of the first hole 99, thus providing an advantage in easily ensuring space for the second hole 94.

[0093] Furthermore, in this embodiment, the operating part 97 is provided with two second holes 94. The two second holes 94 are provided along line segment L2 and on both sides of the first hole 99. When the shape of the operating part 97 is circular when viewed from above, since the two second holes 94 are provided at the part of the operating part 97 where the width is greatest in the direction orthogonal to the long axis of the first hole 99, the interval between the two second holes 94 can be widened as much as possible. When the interval between the two second holes 94 is widened, it is easier to use the second tool T2 to rotate the locking member 95.

[0094] <Middle Frame> Molded articles of 30 series synthetic resin, for example (refer to Fig. 1, Fig. 6~9).

[0095] The middle frame 30 has a plate-like portion 31 that is elongated rectangular when viewed from above. The middle frame 30 is disposed in the space surrounded by the wall portion 14 of the housing 10. Furthermore, the middle frame 30 is disposed on the opposite side of the housing 10 from the working surface 100. The plate-like portion 31 of the middle frame 30 is provided with a window opening 32 for exposing the wiring device 60 held by the housing 10.

[0096] On the left side of the plate-shaped portion 31, three mounting pieces 33 are provided at positions corresponding to the three sets of protrusions 16 provided on the inner left side of the wall portion 14 of the housing 10. Two of the mounting pieces 33A located above and below the left side of the plate-shaped portion 31 have recesses 34 that engage with the fitting protrusions 19 provided on the wall portion 14. Furthermore, on the left side of the plate-shaped portion 31, six recesses 35 are provided that engage with the six protrusions 16 provided on the inner left side of the wall portion 14 of the housing 10. That is, the middle frame 30 has recesses 35 into which the protrusions 16 of the housing 10 can be inserted.

[0097] Similarly, on the right side of the plate-shaped portion 31, three mounting pieces 33 are provided at positions corresponding to the three sets of protrusions 16 provided on the inner side of the right side of the wall portion 14 of the housing 10. Among the three mounting pieces 33, the two mounting pieces 33A located above and below the right side of the plate-shaped portion 31 are provided with recesses 34 that engage with the fitting protrusions 19 provided on the wall portion 14. Furthermore, on the right side of the plate-shaped portion 31, six recesses 35 are provided that engage with the six protrusions 16 provided on the inner side of the right side of the wall portion 14 of the housing 10.

[0098] Here, the fitting protrusion 19 provided on the wall portion 14 becomes the first fitting portion, and the recess 34 provided on the mounting piece 33A becomes the second fitting portion that can fit with the first fitting portion, i.e., the fitting protrusion 19. That is, a mounting piece 33A protruding from the plate-shaped portion 31 along the normal direction of the plate-shaped portion 31 is provided on the periphery of the plate-shaped portion 31, and a second fitting portion that can fit with the first fitting portion is provided on the mounting piece 33A.

[0099] Here, in the normal direction of the plate-shaped portion 31, the positions of the recesses 34 provided in the four mounting pieces 33A are offset from the position of the plate-shaped portion 31 (refer to FIG. 9). That is, in the normal direction of the plate-shaped portion 31, the position of the second fitting portion is offset from the position of the plate-shaped portion 31. Furthermore, the position of the recess 34 in the normal direction of the plate-shaped portion 31 is the position where the depth of the recess 34 is the deepest, and this position is offset from the position of the plate-shaped portion 31 in the normal direction of the plate-shaped portion 31.

[0100] The plate-shaped portion 31 has a first surface 31A and a second surface 31B facing each other in the normal direction of the plate-shaped portion 31. In this embodiment, as shown in FIG9, when the middle frame 30 is arranged with the first surface 31A facing upward and the second surface 31B facing downward, the position of the recess 34 provided in the mounting piece 33A is located lower than the first surface 31A.

[0101] Therefore, the position of the middle frame 30 on the first surface 31A when the second surface 31B of the plate-shaped portion 31 faces the construction surface 100 is offset from the position of the middle frame 30 on the second surface 31B when the first surface 31A of the plate-shaped portion 31 faces the construction surface 100 in the normal direction.

[0102] In detail, the distance D1 from the first surface 31A to the back of the waterproof gasket 90 in the first installation state (refer to Figure 9) is greater than the distance D2 from the second surface 31B to the back of the waterproof gasket 90 in the second installation state (refer to Figure 11) (refer to Figure 11). The first installation state is an installation state in which the housing 10 with the middle frame 30 is installed on the construction surface 100 with the second surface 31B facing rearward and the first surface 31A facing forward. The second installation state is an installation state in which the housing 10 with the middle frame 30 is installed on the construction surface 100 with the first surface 31A facing rearward and the second surface 31B facing forward.

[0103] For example, as wiring harnesses 60, there are two types, 60A and 60B, with different front-to-back dimensions of the body 61. It is assumed that wiring harness 60A has a longer distance from the work surface 100 to the front of the body 61 compared to wiring harness 60B. In this case, the front of wiring harness 60A, mounted on the work surface 100 via the mounting frame 70, is further forward than the front of wiring harness 60B, which is also mounted on the work surface 100 via the mounting frame 70. When wiring harness 60A is mounted on the work surface 100, as shown in FIG9, simply mounting the middle frame 30 to the housing 10 with the first surface 31A facing forward reduces the height difference between the front of wiring harness 60A and the first surface 31A of the middle frame 30. On the other hand, when the wiring device 60B is installed on the construction surface 100, as shown in FIG11, the middle frame 30 can be installed on the housing 10 with the second side 31B facing forward, which can reduce the height difference between the front of the wiring device 60B and the second side 31B of the middle frame 30.

[0104] Furthermore, when the middle frame 30 is disposed on the housing 10 with the second surface 31B of the plate-shaped portion 31 facing the construction surface 100, the middle frame 30 is restricted from moving further toward the construction surface 100 by contacting the limiting protrusion 18 of the housing 10 with the rear end of the mounting piece 33. Thus, the housing 10 is provided with a limiting protrusion 18 that restricts the movement of the middle frame 30 toward the construction surface 100 by contact with the middle frame 30. Therefore, the movement of the middle frame 30 toward the construction surface 100 side can be suppressed, preventing a height difference from forming between the second surface 31B of the middle frame 30 and the front surface of the wiring device 60.

[0105] (2.1.4) The waterproof liner wiring device 1 further includes a waterproof liner 90 installed between the housing 10 and the construction surface 100.

[0106] The waterproof pad 90 is formed into a rectangular frame shape by means of an elastic material such as synthetic rubber.

[0107] With the waterproof gasket 90 sandwiched between the housing 10 and the construction surface 100, the housing 10 and the waterproof gasket 90 are fixed to the construction surface 100 by screwing the screw through the insertion hole 150 of the housing 10 into the screw hole 77 of the mounting frame 70 fixed to the construction surface 100 through the mounting frame 70.

[0108] When the waterproof gasket 90 is sandwiched between the housing 10 and the construction surface 100, and the housing 10 is fixed to the construction surface 100, the gap between the housing 10 and the construction surface 100 is sealed by the waterproof gasket 90. Therefore, the possibility of water flowing into the gap between the housing 10 and the construction surface 100 and intruding into the wiring device 60 can be reduced, and the possibility of short circuits and other defects can be reduced.

[0109] (2.2) Explanation of the installation method on the construction surface: The installation method of installing the wiring device 1 of this embodiment on the construction surface 100 will be explained. Furthermore, the installation method described below is only one example, and the installation sequence may be appropriately changed.

[0110] First, the insulating cover 80 is installed on the mounting frame 70, which is integrally mounted with the wiring device 60. As shown in FIG12, the insulating cover 80, with the face of the snap-fit ​​part 85 facing forward, is brought closer to the rear of the mounting frame 70, and the rib 88 is inserted into the insertion hole 75, while the snap-fit ​​part 85 is inserted into the hole 76. At this time, the mounting frame 70 positions the insulating cover 80 by the rib 88 contacting the end face of the insertion hole 75. Furthermore, when the snap-fit ​​part 85 is inserted into the hole 76, the claw 87 at the front end of the plate-shaped part 86 is pressed against the end face of the hole 76, thereby causing the plate-shaped part 86 to elastically deform in a direction away from the end face of the hole 76. Thus, when the plate-shaped part 86 is further inserted into the hole 76 and the claw 87 passes through the end face of the hole 76, the plate-shaped part 86 returns to the state before elastic deformation. At this time, the claw 87 hooks onto the front of the horizontal piece 72, thereby preventing the snap-fit ​​part 85 from loosening, and allowing the insulating cover 80 to be installed on the mounting frame 70.

[0111] Next, the mounting frame 70 is fixed to the construction surface 100. The rear part of the wiring device 60 installed on the mounting frame 70 is inserted into the recessed hole 101 provided in the construction surface 100, and the pair of cross plates 82 of the insulating cover 80 installed on the mounting frame 70 are brought into contact with the periphery of the recessed hole 101 in the construction surface 100. Then, the mounting frame 70 with the insulating cover 80 is fixed to the construction surface 100 by screwing the screws 300 (refer to FIG. 13) inserted into the insertion hole 75 of the mounting frame 70 and the through hole 84 of the insulating cover 80 into the screw holes of the wiring box embedded in, for example, the inside of the construction surface 100.

[0112] Next, install the wiring device box 2 into the mounting frame 70 fixed to the construction surface 100.

[0113] First, with the retaining springs 55 facing rearward, insert the spring member 50 from the front into the recess 574 of the spring retaining member 56, and insert the four retaining springs 55 into the four mounting grooves 573 provided on the base 57 (refer to FIG. 4). Next, when the spring member 50 is inserted until the bent portions of the four retaining springs 55 engage with the rear end of the base 57, the spring member 50 is mounted on the spring retaining member 56 by the engagement of the four retaining springs 55 with the rear end of the base 57. With the spring member 50 mounted on the spring retaining member 56, the four retaining springs 55 abut against the left and right end faces of the four mounting grooves 573, thereby restricting the movement of the spring member 50 in the left and right directions.

[0114] Subsequently, the spring retaining member 56 for retaining the retaining spring 55 is inserted from the rear of the housing 10 into the internal space of the first bearing portion 111. When the spring retaining member 56 is inserted until the pivot support portion 58 contacts the inner surface of the first bearing portion 111, the protrusion 575 of the spring retaining member 56 hooks into the recess of the housing 10, thereby restricting the rearward movement of the spring retaining member 56. Furthermore, by the base 57 and the pivot support portion 58 contacting the inner surface of the first bearing portion 111, the forward movement and vertical movement of the spring retaining member 56 are respectively restricted. In this way, the spring retaining member 56, on which the retaining spring 55 is mounted, is retained by the housing 10. With the spring holding member 56, on which the holding spring 55 is installed, held by the housing 10, the circular hole of the pivot support portion 58 of the spring holding member 56 and the two leaf spring portions 51 of the spring member 50 are arranged between the left and right shaft insertion holes 11 of the first bearing portion 111.

[0115] Next, with the waterproof gasket 90 overlapping the rear side of the housing 10, the housing 10 and the waterproof gasket 90 are positioned on the construction surface 100 such that the mounting frame 70 is inserted into the inner side of the wall portion 14 of the housing 10. In this state, the housing 10 is fixed to the mounting frame 70 (see FIG. 7) by screwing the screw 310 through the insertion hole 150 of the housing 10 into the screw hole 77 of the mounting frame 70. In this way, the housing 10 is mounted on the construction surface 100 via the mounting frame 70 and the insulating cover 80.

[0116] Next, the middle frame 30 is installed on the housing 10. For example, with the first surface 31A facing forward, when the middle frame 30 is inserted from the front into the space surrounded by the wall portion 14 of the housing 10, the six mounting pieces 33 respectively provided on the left and right sides of the plate-shaped portion 31 are each inserted between the corresponding two protrusions 16. At this time, the four fitting protrusions 19 provided on the wall portion 14 abut against their respective corresponding mounting pieces 33A, causing the mounting pieces 33A to bend inward. When the middle frame 30 is pressed further back, the fitting protrusions 19 enter the recesses 34 of the mounting pieces 33A, so that the fitting protrusions 19 and the recesses 34 fit together, thereby installing the middle frame 30 on the housing 10.

[0117] Subsequently, the cover 20 is brought closer to the front of the housing 10, and the first bearing portion 111 of the housing 10 is inserted into the recess 242 located on the upper side of the cover 20. Next, when the rotating shaft 40 is inserted into a pair of shaft holes 25 provided on the left and right side walls 22 of the cover 20, the front end of the rotating shaft 40 is inserted into the shaft insertion hole 11 of the first bearing portion 111. At this time, the polygonal cylindrical shaft portion 41 at the front end of the rotating shaft 40 is inserted between a pair of flat plates 52 of the leaf spring portion 51 through the round hole of the pivot support portion 58. Furthermore, the claws of the pair of clamping pieces 572 of the shaft stopping portion 571 are engaged in the groove 45 of the rotating shaft 40, thereby preventing the rotating shaft 40 from protruding from the shaft insertion hole 11. Furthermore, the protruding portion 44 of the rotating shaft 40 is inserted into the keyway 251 of the cover 20, thereby restricting the rotation of the cover 20 relative to the rotating shaft 40, and causing the rotating shaft 40 and the cover 20 to rotate as a unit. Also, since the rotating shaft 40 is inserted into the circular hole of the pivot support portion 58 of the spring holding member 56 mounted on the housing 10, the rotating shaft 40 is supported in a rotatable manner relative to the housing 10, and the cover 20 is rotatably supported on the housing 10 via the rotating shaft 40. Thus, the cover 20 is supported in a rotatable manner relative to the housing 10 with the central axis of the rotating shaft 40 as the center of rotation. Furthermore, since the polygonal columnar shaft portion 41 of the front end of the rotating shaft 40 is inserted between a pair of flat plate portions 52 of the leaf spring portion 51, the cover 20 is stably held at the positions where the two surfaces 42 of the polygonal columnar shaft portion 41 in opposite directions contact the surfaces of the pair of flat plate portions 52. That is, the cover 20 can be fixed in a rotational position where the two surfaces 42 of the pair of flat plates 52 and the polygonal prism shaft 41 are in surface contact. Here, when the cover 20 is rotated to a position where the rear ends of the side wall 22 and the lower wall 23 of the cover 20 are in contact with the front of the housing 10 (this position is called the closed position), the rotation shaft 40 is mounted on the cover 20 such that the two surfaces 42 of the polygonal prism shaft 41 in opposite directions are in surface contact with the pair of flat plates 52. Since the cross-sectional shape of the polygonal prism shaft 41 is a regular hexahedron, when the cover 20 is rotated 60 degrees or 120 degrees from the closed position, the two surfaces 42 of the polygonal prism shaft 41 in opposite directions are in surface contact with the pair of flat plates 52. Therefore, the cover 20 is stably fixed in a position rotated 60 degrees from the closed position or in a position rotated 120 degrees. Figure 5 shows the state in which the cover 20 is fixed in a position rotated 120 degrees from the closed position. Furthermore, the cover 20 can be rotated to a position where, for example, the upper wall 24 of the cover 20 contacts the work surface 100, and any position between the position of the cover 20 when the upper wall 24 of the cover 20 contacts the work surface 100 and the closed position becomes the open position of the cover 20.

[0118] (2.3) Explanation of usage method The usage method of the wiring device 1 is explained with the wiring device 1 installed on the construction surface 100.

[0119] With the locking member 95 rotated to the unlocked position, the cover 20 can be opened and closed. The user rotates the cover 20 from the closed position to, for example, 120 degrees, thus opening the cover 20. In this state, when the user connects the plug of an electrical appliance to the plug insertion port 64 of the wiring device 60, power is supplied from the wiring device 60 to the electrical appliance.

[0120] In this state, the user rotates the cover 20 to the closed position, and sets it to a position where the cable of the electrical device whose plug is connected to the plug insertion port 64 is pulled out to the outside through the recess 27 of the cover 20. Subsequently, when the user uses the first tool T1 or the second tool T2 to rotate the locking member 95 from the unlocked position to the locked position, the locking piece 98 on the locking member 95 interferes with the hook portion 17 of the housing 10, thereby securing the cover 20 in the closed position. Therefore, it is possible to prevent the plug of the electrical device connected to the plug insertion port 64 from being removed by a third party.

[0121] Furthermore, when the user removes the plug of the electrical device connected to the plug socket 64, the user uses the first tool T1 or the second tool T2 to rotate the locking member 95 from the locked position to the unlocked position. At this time, since the locking piece 98 provided on the locking member 95 moves to a position where it does not interfere with the hook portion 17 of the housing 10, the cover 20 can be moved from the closed position to the open position. With the cover 20 in the open position, the user can remove the plug of the electrical device connected to the plug socket 64.

[0122] (3) Modifications The above embodiments are only one of the various embodiments of the present invention. The above embodiments can be modified in various ways, such as design, as long as the purpose of the present invention can be achieved.

[0123] Hereinafter, variations of the above embodiments are listed. The variations described below can be combined and applied appropriately.

[0124] In the above embodiment, the wiring device 60 is a power socket, but the wiring device 60 may also be a switch or the like.

[0125] In the above embodiment, the first fitting part of the housing 10 provided on the inner side of the wall portion 14 is a fitting protrusion 19, and the second fitting part provided on the mounting piece 33A is a recess 34. Alternatively, the second fitting part may be a protrusion and the first fitting part may be a recess.

[0126] In the above embodiment, the shape and arrangement of the first hole 99 and the second hole 94 provided in the operating part 97 of the locking member 95 are one example, but can be appropriately changed. Also, in the above embodiment, the number of the second hole 94 is two, but the number of the second hole 94 can be one or more.

[0127] (Conclusion) The following pattern is revealed from the above-described implementation forms, etc.

[0128] The first-state wiring device box (2) includes: a housing (10), a cover (20), and a middle frame (30). The housing (10) can hold the wiring device (60) and can be installed on the construction surface (100). The cover (20) is supported between a closed position that covers the wiring device (60) held by the housing (10) and an open position that exposes the wiring device (60) held by the housing (10) in a rotatable manner relative to the housing (10). The middle frame (30) has a plate-shaped portion (31) with a window (32) that exposes the wiring device (60) held by the housing (10), and is disposed on the opposite side of the construction surface (100) to the housing (10). The housing (10) has a wall portion (14) facing the periphery of the plate-shaped portion (31). A first fitting portion (19) is provided in the wall portion (14) opposite to the plate-shaped portion (31). A mounting piece (33A) protruding from the plate-shaped portion (31) along the normal direction of the plate-shaped portion (31) is provided at the periphery of the plate-shaped portion (31). A second fitting portion (34) is provided on the mounting piece (33A) that can fit into the first fitting portion (19). The position of the second fitting portion (34) is offset from the position of the plate-shaped portion (31) in the normal direction of the plate-shaped portion (31).

[0129] If the two surfaces of the plate-shaped portion (31) in opposite directions in the normal direction (i.e., the thickness direction) are designated as the first surface (31A) and the second surface (31B), then the position of the second surface (31B) when the middle frame (30) is installed on the housing (10) with the first surface (31A) facing the construction surface (100) is offset from the position of the first surface (31A) when the middle frame (30) is installed on the housing (10) with the second surface (31B) facing the construction surface (100) in the normal direction. Therefore, when there are two types of wiring harnesses (60) with different distances from the mounting frame (70) to the front of the wiring harness (60) while the wiring harness (60) is held by the mounting frame (70), the inner and outer surfaces of the middle frame (30) can be replaced according to the size of the wiring harness (60) and installed on the housing (10). Therefore, the wiring harness box (2) based on this state has the advantage of being able to install two different sizes of wiring harnesses (60).

[0130] In the wiring harness box (2) of the second state sample, in the first state sample, the plate-shaped part (31) has a first surface (31A) and a second surface (31B) in opposite directions in the normal direction. The position of the first surface (31A) when the second surface (31B) of the plate-shaped part (31) is facing the construction surface (100) is offset from the position of the second surface (31B) when the plate-shaped part (31) is facing the construction surface (100) and the position of the second surface (31B) when the plate-shaped part (31) is facing the construction surface (100) is offset in the normal direction.

[0131] Based on this configuration, it has the advantage of being able to install two different sizes of wiring devices (60).

[0132] In the wiring harness box (2) of the third state sample, in the first or second state sample, a protrusion (16) is provided in the part of the wall portion (14) opposite to the plate portion (31) in a manner parallel to the first fitting portion (19). A recess (35) is provided in the middle frame (30) into which the protrusion (16) can be inserted.

[0133] According to this configuration, the protrusion (16) can be inserted into the recess (35), thereby positioning the middle frame (30) against the housing (10).

[0134] In the wiring fixture box (2) of the fourth state sample, in the third state sample, a limiting protrusion (18) is provided in the housing (10) to restrict the movement of the middle frame (30) towards the construction surface (100) by contact with the middle frame (30).

[0135] According to this configuration, the middle frame (30) can be restricted to moving towards the construction surface (100) beyond the position of abutting the restricting protrusion (18) in the normal direction of the plate-shaped part (31).

[0136] In the wiring device box (2) of the fifth type, in any of the first to fourth types, a mounting frame (70) for mounting wiring devices can be installed on the housing (10). In the mounting frame (70), a pair of screw holes (77) are provided on both sides of the opening (71) where the wiring device (60) is disposed. In the housing (10), a pair of through holes (150) are provided for inserting one of the pair of screws (300) locked into the pair of screw holes (77). The shape of each of the pair of through holes (150) is formed by connecting the first through hole (151) and the second through hole (152). The first through hole (151) is a hole in which a screw (300) locked into the pair of screw holes (77) can be inserted when the interval between the pair of screw holes (77) is the first interval (W1). The second through hole (152) is a hole into which a screw (300) that is locked into a pair of screw holes (77) can be inserted when the interval between the two screw holes (77) is the second interval (W2).

[0137] Based on this configuration, the housing (10) can be installed in either the mounting frame (70) with a first interval (W1) between a pair of screw holes (77) or the mounting frame (70) with a second interval (W2) between a pair of screw holes (77).

[0138] In the wiring harness box (2) of the sixth embodiment, in any of the first to fifth embodiments, a locking member (95) and a locking piece (98) are further provided. The locking member (95) has an operating part (97) protruding to the outside of the cover (20), and is held in a rotatable state relative to the cover (20) with the operating part (97) protruding to the outside of the cover (20). The locking piece (98) protrudes from the locking member (95) in a direction intersecting the direction along the rotation center, i.e., the central axis of the locking member (95). By rotating together with the locking member (95), the locking piece (98) can move between a locked position that engages with the hook part (17) of the housing (10) and an unlocked position that disengages from the hook part (17). The tools for rotating the locking member (95) include a first tool (T1) and a second tool (T2) with different front end shapes. The operating part (97) is provided with a first hole (99) for inserting the front end portion (200) of the first tool (T1) and a second hole (94) for inserting the front end portion (210) of the second tool (T2).

[0139] Based on this configuration, the locking member (95) can be moved between the unlocked position and the locked position using either the first tool (T1) or the second tool (T2).

[0140] In the wiring fixture box (2) of the seventh state sample, in the sixth state sample, the first hole (99) is a rectangular hole when viewed from above. A second hole (94) is provided along a line segment (L2) that passes through the center of the long axis of the first hole (99) and is orthogonal to the long axis of the first hole (99).

[0141] Based on this configuration, it has the advantage of making it easy to operate the part (97) to ensure space for the second hole (94).

[0142] In the wiring harness box (2) of the eighth state sample, and in the seventh state sample, two second holes (94) are provided in the operation section (97). The two second holes (94) are arranged on both sides of the first hole (99) along the line segment (L2).

[0143] Based on this configuration, it has the advantage of making it easy to operate the part (97) to ensure space for the second hole (94).

[0144] The wiring device (1) of the ninth state includes: a wiring device box of any one of the first to eighth states, and a wiring device (60) held by the housing (10).

[0145] Based on this configuration, it has the advantage of being able to install two different sizes of wiring devices (60).

[0146] The wiring device device (1) of the 10th state, compared with the 9th state, further includes a mounting frame (70) that can be installed on the construction surface (100) while holding the wiring device (60). The housing (10) can be fitted with the mounting frame (70) for holding the wiring device (60). The housing (10) is provided with a through hole (12) into which the wiring device (60) held by the mounting frame (70) can be inserted.

[0147] Based on this configuration, it has the advantage of being able to install two different sizes of wiring devices (60).

[0148] The wiring device (1) of the 11th state, which is the same as that of the 10th state, further includes: an insulating cover (80) disposed between the mounting frame (70) and the working surface (100). The insulating cover (80) is provided with a snap-fit ​​part (85) that can be attached to and detached from the hole (76) provided in the mounting frame (70).

[0149] Based on this configuration, the insulating cover (80) can be installed on the mounting frame (70) without the need for special tools.

[0150] The wiring device (1) of the 12th type, which is in any of the 9th to 11th types, further includes: a waterproof gasket (90) installed between the housing (10) and the working surface (100).

[0151] Based on this configuration, the gap between the housing (10) and the construction surface (100) can be sealed by a waterproof gasket (90).

[0152] For the configuration of states 2 to 8, the wiring device box (2) is not a necessary component and can be omitted appropriately. For the configuration of states 10 to 12, the wiring device device (1) is not a necessary component and can be omitted appropriately. [Simplified Explanation of the Diagram]
