The connection member 6 is accommodated within the housing 5 . The connection member 6 is electrically connected with the plug 2 . The front surface 501 is formed with an insertion port 7 for inserting the plug 2 . At least a portion of the front surface 501 is an undulating surface 8 that includes at least one of a plurality of recesses 801 (see FIG. 5A) and a plurality of protrusions 802 (see FIG. 5A).

According to the configuration described above, since at least part of the front surface 501 is the undulating surface 8 , various functions can be provided by the undulating surface 8 to the front surface 501 of the housing 5 in which the insertion port 7 is formed. . As an example of the function of the undulating surface 8, there is a function of making dirt less likely to adhere (easier to remove), less likely to be scratched, or less likely to cause excessive light reflection. For example, when dirt is less likely to adhere, changes in the electrical properties of the outlet device 1 due to dirt are less likely to occur. As described above, the outlet device 1 according to the present embodiment has the advantage that various functions can be provided to the outlet device 1 without adding a separate member such as an outlet cover to the outlet device 1. .

In the outlet system 10 according to this embodiment, at least a portion of the surface 411 of the outlet plate 4 is the undulating surface 8 .

(2) Details Hereinafter, configurations of the outlet device 1 and the outlet system 10 according to the present embodiment will be described in detail with reference to FIGS. 1 to 5B.

(2.1) Premises In the present embodiment, as the outlet device 1, a two-outlet type outlet for AC 100 V without a ground pole and to which two plugs 2 can be connected is exemplified. Further, in this embodiment, an indoor outlet used inside a building is exemplified as the outlet device 1 . The building in which the outlet device 1 is used is, for example, a residential facility such as a detached house or collective housing, or a non-residential facility such as an office, store, school, factory, hospital, or nursing care facility.

Moreover, in this embodiment, as an example, a case where the outlet device 1 is fixed to the wall of a residential facility will be described. That is, the mounting object 3 is a wall of a residential facility (building). Furthermore, in the present embodiment, as an example, the case where the outlet device 1 is an “embedded” wiring device whose rear part is embedded in the installation hole 31 (see FIG. 3) of the mounting object 3 will be described.

Hereinafter, the direction perpendicular to (perpendicular to) the horizontal plane in the state where the outlet device 1 is fixed to the wall of the housing facility, which is the mounting object 3, is defined as the "vertical direction", and the outlet device 1 is viewed from the front. The downward direction (vertical direction) may be described as “downward”. Further, the direction orthogonal to the vertical direction and parallel to the surface of the mounting object 3 is defined as the "left and right direction", the right direction as viewed from the front of the outlet device 1 is defined as the "right direction", and the left direction is defined as the "left direction". may explain. Further, the direction orthogonal to both the vertical direction and the horizontal direction, that is, the direction orthogonal to the surface of the mounting object 3 is defined as the "front-back direction", and the back side (wall back side) of the mounting object 3 is defined as the "rear". sometimes. However, these directions are not intended to limit the directions when the outlet device 1 is used.

In addition, the front surface 501 of the housing 5 basically faces forward when the outlet device 1 is fixed to the wall of the housing facility, which is the mounting object 3. However, the front surface 501 faces forward. It is not intended to limit For example, when the outlet device 1 is installed on the ceiling, the front surface 501 faces downward (in the direction of gravity).

As used in this disclosure, a "relief surface" means a surface that includes at least one of a plurality of recesses 801 (see FIG. 5A) and a plurality of protrusions 802 (see FIG. 5A). That is, the undulating surface 8 may be composed only of the plurality of concave portions 801 or may be composed only of the plurality of convex portions 802 . Furthermore, the undulating surface 8 may be composed of a plurality of concave portions 801 and one convex portion 802 . In this case, as an example, the undulating surface 8 is composed of one net-like convex portion 802 and a plurality of concave portions 801 formed of mesh portions surrounded by the convex portion 802 . Similarly, as an example, the undulating surface 8 may be composed of one mesh-like concave portion 801 and a plurality of convex portions 802 formed of mesh portions surrounded by the concave portion 801 .

As an example in this embodiment, the undulating surface 8 includes a plurality of concave portions 801 and a plurality of convex portions 802 . The plurality of concave portions 801 and the plurality of convex portions 802 on the undulating surface 8 have extremely small sizes that cannot be individually identified with the naked eye, and one undulating surface 8 has a large number of concave portions 801 and a large number of convex portions. 802 will be included. That is, the concave portions 801 and the convex portions 802 are finer than the entire undulating surface 8 . As a result, when a person looks at the undulating surface 8, the recesses 801 and the projections 802 make the undulating surface 8 look like a rough “satin finish”. The undulating surface 8 including a large number of such minute concave portions 801 and convex portions 802 is formed by texturing, for example.

Such an undulating surface 8 has, as a whole, a pattern (uneven shape) such as a satin finish, wrinkle pattern (emboss), wood grain, rock grain, sand grain, or geometric pattern due to a large number of concave portions 801 and convex portions 802. It will be.

In addition, the size of such minute concave portions 801 and convex portions 802 can be represented by the surface roughness of the undulating surface 8 . is reflected in the roughness curve of Therefore, the size of the concave portions 801 and the convex portions 802 on the undulating surface 8 corresponds to the arithmetic mean roughness (Ra) of the undulating surface 8 .

In each figure (FIGS. 1A and 1B, etc.) in the present disclosure, the range (region) where the undulating surface 8 is formed is hatched (dot hatching). In other words, the hatching that represents the undulating surface 8 is merely added for convenience to represent the range of the undulating surface 8, and the actual undulating surface 8 is not shaded. Furthermore, as will be described in detail in the section "(2.4) Undulating surface", the undulating surface 8 can be It is classified into a first undulating surface 81 and a second undulating surface 82 . Therefore, the first undulating surface 81 and the second undulating surface 82 are distinguished from each other even in the drawing by changing the type of meshing between the first undulating surface 81 and the second undulating surface . However, when the first undulating surface 81 and the second undulating surface 82 are not particularly distinguished, each of the first undulating surface 81 and the second undulating surface 82 is simply referred to as "the undulating surface 8".

In addition, the term “perpendicular” as used in the present disclosure means not only a state in which they intersect at exactly 90 degrees, but also a state in which they are substantially perpendicular to each other within a certain margin of error. In other words, the angle between the surface of the mounting object 3 and the front-rear direction is within a certain range of error (for example, 10 degrees or less) with respect to 90 degrees. In this embodiment, as an example, the angle between the surface of the mounting object 3 and the front-rear direction is 90 degrees. Similarly, the term “parallel” as used in the present disclosure includes not only a state where the angle between the two is strictly 0 degrees, but also a state where the two are substantially parallel within a certain margin of error.

(2.2) Overall Configuration First, the overall configuration of the outlet system 10 will be described with reference to FIGS. 2 and 3. FIG.

The outlet system 10 according to this embodiment includes the outlet device 1 and the outlet plate 4 as described above. Here, the outlet device 1 is fixed to the mounting object 3 using the mounting frame 43 . In this embodiment, the mounting frame 43 is included as a component of the outlet system 10, but it is not essential that the outlet system 10 includes the mounting frame 43 as a component.

In this embodiment, since the outlet device 1 is an embedded wiring device as described above, it is attached to the attachment object 3 (wall in this case) using an attachment member such as an embedded switch box. be done. That is, a mounting hole 31 is formed in the mounting object 3, and the outlet device 1 passes through the mounting hole 31 to a mounting member such as a switch box arranged on the back side (wall back) of the mounting object 3. It is attached.

The mounting frame 43 is, for example, a mounting frame for a large-sized connected wiring device standardized by Japanese Industrial Standards. In this embodiment, the mounting frame 43 is integrated with the outlet device 1 . Specifically, the mounting frame 43 is formed in a rectangular frame shape when viewed from the front. The outlet device 1 and the mounting frame 43 are integrated so that the outlet device 1 is positioned inside the mounting frame 43 . A cover 51 and a body 52 that constitute the housing 5 of the outlet device 1 are coupled by a mounting frame 43 , which will be described in detail in the section “(2.3) Structure of outlet device”.

The mounting frame 43 is made of metal, for example. A pair of mounting holes 431 and a pair of plate fixing holes 432 are formed in the mounting frame 43 . The mounting frame 43 is attached to the mounting object 3 by tightening the pair of mounting screws 44 to a mounting member such as a switch box through the pair of mounting holes 431 .

The outlet plate 4 has a decorative plate 41 and a fixing plate 42 . That is, in this embodiment, the outlet plate 4 is composed of two members, the decorative plate 41 and the fixing plate 42 . The outlet plate 4 (the decorative plate 41 and the fixing plate 42) is made of, for example, a thermoplastic resin such as PBT (Polybutylene Terephthalate), ABS resin, or PC (Polycarbonate). In particular, in the present embodiment, the resin constituting the outlet plate 4 is a so-called original dyed (raw material colored) resin that is colored at the raw material stage before molding by containing a pigment in the base material. By using this type of base resin, the outlet plate 4 (decorative plate 41 and fixing plate 42) can be colored in white, gray, or the like even without coating.

The fixed plate 42 is fixed to the mounting frame 43 . The decorative plate 41 is attached to the fixed plate 42 so as to cover the front surface of the fixed plate 42 (frame surface 421). In this manner, the decorative plate 41 is indirectly fixed via the fixing plate 42 to the mounting frame 43 integrated with the outlet device 1 . A window hole 401 is formed in the decorative plate 41 , and when the outlet plate 4 is attached to the mounting frame 43 , the front surface 501 of the outlet device 1 is exposed through the window hole 401 .

That is, the outlet plate 4 is a frame-like member having a window hole 401 and is combined with the outlet device 1 so that the front surface 501 of the outlet device 1 is exposed through the window hole 401 . In other words, when the outlet device 1 and the outlet plate 4 are assembled together, the front surface 501 of the outlet device 1 is located inside the outlet plate 4 (decorative plate 41) (inside the window hole 401) in a front view. As a result, the outlet plate 4 covers the periphery of the outlet device 1 in a state where the outlet plate 4 is attached to the mounting object 3 together with the outlet device 1, and the mounting frame 43, the construction hole 31, etc. are not exposed. It looks better.

More specifically, the decorative plate 41 is formed in a rectangular frame shape when viewed from the front. A window hole 401 is formed in the central portion of the decorative plate 41 so as to pass through the decorative plate 41 in the front-rear direction. The decorative plate 41 has a surface 411 and side surfaces 412 . A surface 411 corresponds to the front surface of the decorative plate 41 and is located around the window hole 401 . Moreover, the side surface 412 corresponds to the outer peripheral surface of the decorative plate 41 , intersects with the surface 411 and is adjacent to the surface 411 . The decorative plate 41 is mechanically coupled to the fixed plate 42 in a detachable manner by means of a snap-fit structure. In other words, the decorative plate 41 and the fixed plate 42 utilize the elasticity of at least one of the decorative plate 41 and the fixed plate 42 to hook the claws of one of the decorative plate 41 and the fixed plate 42 to the holes of the other, so that the machine can be fixed. are connected systematically.

Further, the fixing plate 42 is formed in a rectangular frame shape when viewed from the front. The fixed plate 42 has a frame surface 421 and a frame side surface 422 . The frame surface 421 corresponds to the front surface of the fixed plate 42 , and the frame surface 421 is covered with the decorative plate 41 when the decorative plate 41 is attached to the fixed plate 42 . Further, the frame side surface 422 corresponds to the outer peripheral surface of the fixing plate 42 and is a surface that intersects the frame surface 421 and is adjacent to the frame surface 421 . Furthermore, a pair of through holes 423 are formed in the fixing plate 42 . The fixing plate 42 is attached to the mounting frame 43 by tightening the pair of fixing screws 45 into the pair of plate fixing holes 432 of the mounting frame 43 through the pair of through holes 423 .

When the outlet plate 4 configured in this manner is attached to the mounting object 3 together with the outlet device 1, only the surface 411, the side surface 412 and the frame side surface 422 of the outlet plate 4 are exposed as shown in FIG. do. That is, when the outlet system 10 is installed, the surface 411 and the side surface 412 of the decorative plate 41 and the frame side surface 422 of the fixing plate 42 of the outlet plate 4 are exposed, and the other surfaces are not exposed. Therefore, in this embodiment, in addition to the surface 411 , at least a part of the side surface 412 and the frame side surface 422 is also the undulating surface 8 . That is, at least a part of the surface 411 , the side surface 412 and the frame side surface 422 of the outlet plate 4 is the undulating surface 8 .

Details will be described in the section of "(2.4) Relief surface". 2 undulating surfaces 82;

(2.3) Configuration of Outlet Device Next, the configuration of the outlet device 1 will be described in more detail with reference to FIGS. 1A, 1B, and 4A to 4D.

The outlet device 1 includes the housing 5 and the connection member 6 as described above. Further, the outlet device 1 includes terminals and the like for connecting wiring (electric wires).

The housing 5 has a cover 51 and a body 52 .

The cover 51 is formed in a box shape having an opening on the rear surface. The body 52 is combined with the cover 51 from behind to cover the opening surface (rear surface) of the cover 51 . The body 52 is formed in a box-like shape having an opening on the front surface facing the cover 51 . In this embodiment, both the cover 51 and the body 52 are formed in a rectangular shape that is longer in the vertical direction than in the horizontal direction when viewed from the front. Furthermore, the cover 51 and the body 52 have substantially the same shape when viewed from the front.

The rectangular parallelepiped housing 5 is configured by combining the cover 51 and the body 52 in the front-rear direction. The housing 5 accommodates the connection member 6 and internal parts such as a terminal plate that constitutes a terminal. In short, the socket device 1 has a housing 5 consisting of a cover 51 and a body 52, and the cover 51 and the body 52 are joined together so as to house internal parts in the internal space of the housing 5. As shown in FIG.

Here, both the cover 51 and the body 52 that constitute the housing 5 are made of synthetic resin having electrical insulation. The cover 51 and the body 52 are made of a thermosetting resin having excellent tracking resistance, such as urea resin. In particular, in this embodiment, the portion of the housing 5 including the front surface 501, that is, the cover 51 is made of urea resin. Further, in this embodiment, not only the cover 51 but also the body 52 are made of urea resin. If at least one of the cover 51 and the body 52 is made of a thermoplastic resin, one of the cover 51 and the body 52 is provided with a claw and the other is provided with a hole into which the claw is fitted, so that the cover 51 can be secured by a snap-fit structure. and bodies 52 are feasible. That is, the cover 51 and the body 52 can be connected by fitting the claws into the holes while elastically deforming either the cover 51 or the body 52 .

On the other hand, when the cover 51 and the body 52 are made of a thermosetting resin as in the present embodiment, it is difficult to impart sufficient elasticity to the cover 51 and the body 52. structure is difficult to adopt. Therefore, in the outlet device 1 according to the present embodiment, the cover 51 and the body 52 are mechanically coupled by the mounting frame 43 which is a separate member from the cover 51 and the body 52, as described above.

In this embodiment, as an example, the mounting frame 43 mechanically couples the cover 51 and the body 52 at four points. Specifically, the cover 51 has first protrusions 512 that protrude from both lateral end surfaces (cover side surfaces 511 ) of the cover 51 . Similarly, the body 52 has second protrusions 522 that protrude from both lateral end surfaces (body side surfaces 521 ) of the body 52 . The mounting frame 43 couples the body 52 and the cover 51 by being attached to the housing 5 so as to hold the first protrusion 512 and the second protrusion 522 from both sides in the front-rear direction. In other words, the mounting frame 43 sandwiches the first protrusion 512 and the second protrusion 522 in the front-rear direction in a state in which the body 52 and the cover 51 are combined in the front-rear direction. It prevents the two protrusions 522 from being relatively separated. As a result, the body 52 and the cover 51 are prevented from opening, and the body 52 and the cover 51 are joined together.

In this embodiment, two pairs (two sets) of first protrusions 512 are provided on both end surfaces (left end surface and right end surface) of the cover 51 in the left-right direction. The two pairs of first protrusions 512 are provided at four corners of the housing 5 when viewed from the front so as to be vertically aligned on each of the lateral end faces (left end face or right end face) of the housing 5 . Similarly, two pairs (two sets) of second protrusions 522 are provided on both end surfaces (left end surface and right end surface) of the body 52 in the left-right direction. The two pairs of second protrusions 522 are provided at the four corners of the housing 5 when viewed from the front so as to be aligned in the vertical direction on each end surface (left end surface or right end surface) of the housing 5 in the left-right direction. Therefore, the body 52 and the cover 51 are joined at the four corners of the housing 5 viewed from the front.

More specifically, cover 51 has a front surface 501 and cover side surfaces 511 . The front face 501 corresponds to the front face 501 of the housing 5 . The cover side surface 511 corresponds to the outer peripheral surface of the cover 51 and is a surface that intersects with the front surface 501 and is adjacent to the front surface 501 . A plurality of insertion openings 7 for inserting the plugs 2 are formed on the front surface 501 . The plug 2 is electrically connected to the outlet device 1 by inserting the insertion pieces 21 of the plug 2 into the plurality of insertion openings 7 . Here, as shown in FIG. 4A, the outlet device 1 has two pairs of receptacles 7 to fit a plug 2 having a pair of power poles (L pole and N pole). there is Each set of insertion openings 7 is formed in a shape adapted to the A-type plug 2 . The two receptacles 7 of each set are arranged side by side in the left-right direction. Furthermore, the two sets of insertion openings 7 are arranged side by side in the vertical direction.

Furthermore, the inner peripheral surface 71 of the receptacle 7 has a tapered surface 701 and an inner surface 702 as shown in FIGS. 1B and 4C. The tapered surface 701 is inclined with respect to the front-rear direction (the direction in which the plug 2 is inserted) so that the cross-sectional area of the insertion port 7 perpendicular to the direction in which the plug 2 is inserted increases toward the front end. The inner side surface 702 is a surface continuous with the rear end portion of the tapered surface 701 and orthogonal to the front surface 501 . In other words, a tapered surface 701 directed obliquely forward is provided near the front end (opening surface) of the inner peripheral surface 71 of the insertion port 7 . That is, near the front end (opening surface) of the insertion port 7 , the cross-sectional area of the insertion port 7 is made smaller toward the rear end side by the tapered surface 701 . Therefore, when the insertion piece 21 of the plug 2 is inserted into the insertion opening 7, the insertion piece 21 is guided by the tapered surface 701 and is inserted to the area surrounded by the inner surface 702. Become.

The body 52 also has body side surfaces 521 . The body side surface 521 corresponds to the outer peripheral surface of the body 52 and is a surface that intersects the front surface 501 . The body side surface 521 constitutes the outer peripheral surface 502 of the housing 5 together with the cover side surface 511 . A terminal hole for connecting an electric wire (wiring) is formed in the rear surface of the body 52 which is the rear surface of the housing 5 . A terminal portion including a terminal plate and the like is accommodated at a position corresponding to the terminal hole in the housing 5 . The terminal portion is a so-called quick connection terminal of an electric wire insertion type to which an electric wire is connected by inserting the electric wire from a terminal hole.

The front surface 501 of the cover 51 corresponds to the front surface 501 of the housing 5 as described above. The cover side surface 511 and the body side surface 521 constitute an outer peripheral surface 502 of the housing 5 . In other words, the outer peripheral surface 502 of the housing 5 includes cover side surfaces 511 and body side surfaces 521 .

When the outlet device 1 configured in this way is attached to the mounting object 3 together with the outlet plate 4, as shown in FIG. Only a portion of the inner peripheral surface 71 of the inlet 7 is exposed. That is, when the outlet system 10 is installed, the front surface 501 of the housing 5, part of the outer peripheral surface 502 of the housing 5, and part of the inner peripheral surface 71 of the receptacle 7 of the outlet device 1 are Exposed, other faces are not exposed. Therefore, in the present embodiment, as shown in FIGS. 4A to 4D, in addition to the front surface 501, at least a portion of the outer peripheral surface 502 and at least a portion of the inner peripheral surface 71 of the insertion port 7 also have the undulating surface 8. is. That is, at least a part of the front surface 501 of the housing 5 , the outer peripheral surface 502 and the inner peripheral surface 71 of the insertion port 7 are the undulating surfaces 8 .

Details will be described in the section "(2.4) Undulating surface". The surface 502 and the inner peripheral surface 71 of the insertion port 7 are the second undulating surface 82 .

(2.4) Relief Surface Next, the relief surface 8 will be described in more detail with reference to FIGS. 2 to 5B.

As described above, the undulating surface 8 is formed on at least part of the front surface 501 and the outer peripheral surface 502 of the housing 5 of the outlet device 1 in this embodiment. Furthermore, at least part of the inner peripheral surface 71 of the insertion port 7 is the undulating surface 8 . In other words, at least a portion of the front surface 501 of the housing 5 , the outer peripheral surface 502 and the inner peripheral surface 71 of the receptacle 7 are the undulating surfaces 8 . Of the front surface 501, the outer peripheral surface 502, and the inner peripheral surface 71 of the insertion port 7, the front surface 501 is the first undulating surface 81, and the outer peripheral surface 502 and the inner peripheral surface 71 of the insertion port 7 are the second undulating surfaces. surface 82 (see FIGS. 4A-4D).

Here, in the present embodiment, as shown in FIG. 4A, the entire front surface 501 is the undulating surface 8 (first undulating surface 81). That is, a plurality of concave portions 801 and a plurality of convex portions 802 are formed on the front surface 501 of the housing 5 substantially evenly over the entire area. In this embodiment, as shown in FIGS. 4B and 4D, the corner between the front surface 501 of the cover 51 and the cover side surface 511 is formed in an R (R) shape when viewed from the side. That is, the corner between the front surface 501 and the outer peripheral surface 502 (cover side surface 511) of the housing 5 is formed in a rounded shape. Therefore, the corner between the front surface 501 and the outer peripheral surface 502 of the housing 5 is visible in front view and is included in the front surface 501 of the housing 5 . Therefore, the corner between the front surface 501 and the outer peripheral surface 502 of the housing 5 is the undulating surface 8 (first undulating surface 81).

As for the outer peripheral surface 502 (cover side surface 511), as shown in FIGS. 4B to 4D, when the outer peripheral surface 502 is divided into two areas in the front-rear direction, only the front end side (front surface 501 side) is provided. is the undulating surface 8 (second undulating surface 82). That is, when the cover side surface 511 is divided into two in the front-rear direction, a plurality of concave portions 801 and a plurality of convex portions 802 are formed only in a region on the front end side (front surface 501 side). 52 side), the concave portion 801 and the convex portion 802 are not formed. Furthermore, in the front end side (front surface 501 side) of the cover side surface 511, the undulating surface 8 (including the concave portions 801 and the convex portions 802) is formed along the entire periphery so as to surround the front surface 501 in a front view. A second undulating surface 82) is formed.

4C, of the tapered surface 701 and the inner surface 702, only the tapered surface 701 is the undulating surface 8 (second undulating surface 82). In other words, on the inner peripheral surface 71 of the insertion port 7 , a plurality of concave portions 801 and a plurality of convex portions 802 are formed only in a region that serves as a tapered surface 701 directed obliquely forward, forming an inner surface 702 . A concave portion 801 and a convex portion 802 are not formed in the region. Further, the tapered surface 701 is formed with an undulating surface 8 (second undulating surface 82) including concave portions 801 and convex portions 802 along the entire circumference so as to surround the insertion port 7 in a front view. .

Further, as described above, the undulating surface 8 is also formed on the surface 411, the side surface 412 and the frame side surface 422 of the outlet plate 4 in this embodiment. In other words, at least a portion of the surface 411 , the side surface 412 and the frame side surface 422 of the outlet plate 4 are the undulating surfaces 8 . Of the surface 411, the side surface 412, and the frame side surface 422, the surface 411 is the first undulating surface 81, and the side surface 412 and the frame side surface 422 are the second undulating surface 82 (see FIGS. 2 and 3).

Here, in the present embodiment, as shown in FIG. 2, the entire surface 411 is the undulating surface 8 (first undulating surface 81). In other words, a plurality of concave portions 801 and a plurality of convex portions 802 are formed on the surface 411 of the outlet plate 4 substantially evenly over the entire surface. In this embodiment, the corner between the surface 411 and the side surface 412 of the outlet plate 4 is formed in an R (R) shape when viewed from the side. That is, the corner between the surface 411 and the side surface 412 of the outlet plate 4 is formed into a rounded shape. Therefore, the corner between the surface 411 and the side surface 412 of the outlet plate 4 is visible in front view and is included in the surface 411 of the outlet plate 4 . Therefore, the corner between the surface 411 and the side surface 412 of the outlet plate 4 is the undulating surface 8 (first undulating surface 81).

Moreover, as shown in FIG. 2, the whole area of the side surface 412 and the frame side surface 422 of the outlet plate 4 is the undulating surface 8 (second undulating surface 82). That is, on the side surface 412 and the frame side surface 422 of the outlet plate 4, a plurality of concave portions 801 and a plurality of convex portions 802 are formed substantially evenly over the entire area. Furthermore, with respect to the side surface 412 and the frame side surface 422 of the outlet plate 4 , the undulating surface 8 (second undulating surface 82 ) including the concave portions 801 and the convex portions 802 is provided along the entire periphery so as to surround the surface 411 in a front view. is formed.

By the way, in the present embodiment, the first undulating surface 81 and the second undulating surface 82 as the undulating surface 8 have the sizes of the concave portions 801 and the convex portions 802 included in the undulating surface 8 (that is, the arithmetic mean roughness of the undulating surface 8). classified by That is, the first undulating surface 81 and the second undulating surface 82 differ in the depth of each concave portion 801 or the height of each convex portion 802 included in the undulating surface 8 . The depth of each concave portion 801 or the height of each convex portion 802 is smaller than that of the undulating surface 81 . In other words, the arithmetic mean roughness (Ra) of the second undulating surface 82 is smaller than the arithmetic mean roughness (Ra) of the first undulating surface 81 . Furthermore, in other words, the first undulating surface 81 is rougher than the second undulating surface 82 because the concave portions 801 and the convex portions 802 are larger in size.

As an example in this embodiment, the ten-point average roughness (Rzjis) of the first undulating surface 81 is 1 μm or more and 100 μm or less. Here, the ten-point average roughness (Rzjis) of the first undulating surface 81 is preferably 10 μm or more. Also, the ten-point average roughness (Rzjis) of the first undulating surface 81 is preferably 35 μm or less. More preferably, the ten-point average roughness (Rzjis) of the first undulating surface 81 may be 25±10 μm. More preferably, the ten-point average roughness (Rzjis) of the first undulating surface 81 may be 25±5 μm. The ten-point average roughness here is a surface roughness parameter standardized by "JIS B 0601-2001".

And, as described above, the housing 5 has an outer peripheral surface 502 that intersects the front surface 501 and is adjacent to the front surface 501 . Here, at least part of the outer peripheral surface 502 is the undulating surface 8 (second undulating surface 82). The undulating surface 8 (second undulating surface 82 ) of the outer peripheral surface 502 has a depth of each of the plurality of concave portions 801 or a depth of the plurality of convex portions 802 compared to the undulating surface 8 (first undulating surface 81 ) of the front surface 501 . Each height is small. As a result, for example, when the housing 5 is molded, even if the mold M1 (see FIG. 6A) is released in a direction orthogonal to the front surface 501, the concave portion of the undulating surface 8 (second undulating surface 82) of the outer peripheral surface 502 is The 801 or the convex portion 802 is hard to crush (collapse).

Further, in this embodiment, not only the outer peripheral surface 502 but also the inner peripheral surface 71 (tapered surface 701) of the insertion port 7 is the second undulating surface 82 . Therefore, the undulating surface 8 (second undulating surface 82 ) of the inner peripheral surface 71 of the insertion port 7 is deeper than the undulating surface 8 (first undulating surface 81 ) of the front surface 501 of each of the plurality of recesses 801 . The width or height of each of the plurality of protrusions 802 is small.

Furthermore, in the outlet plate 4 as well, the surface 411 is the first undulating surface 81 , and the side surface 412 and the frame side surface 422 are the second undulating surfaces 82 . Therefore, the undulating surface 8 (second undulating surface 82) of the side surface 412 and the frame side surface 422 has a depth or more of each of the plurality of recesses 801 compared to the undulating surface 8 (first undulating surface 81) of the surface 411. , the height of each projection 802 is small.

By the way, in the present embodiment, the undulating surface 8 has a substantially uniform pattern (that is, uneven shape) within the same plane. For example, the undulating surface 8 on the front surface 501 has a substantially uniform pattern over its entire area. In other words, if any two portions of the undulating surface 8 included in the same plane (for example, the front surface 501) are partially cut out and compared, these two portions will include substantially the same pattern. However, the undulating surface 8 only has a substantially uniform pattern, and does not have exactly the same pattern continuously like a geometric pattern.

Furthermore, in the present embodiment, the undulating surface 8 has an isotropic pattern (that is, uneven shape) within the same plane. For example, the undulating surface 8 on the front surface 501 has substantially the same pattern in any of two directions (vertical direction and horizontal direction) that are parallel to the front surface 501 and perpendicular to each other. In other words, for the undulating surface 8 included in the same plane (for example, the front surface 501), if a longitudinal section (a section along the vertical direction) and a transverse section (a section along the horizontal direction) are cut out and compared, these two sections can be obtained. contains substantially the same concave and convex shape.

More specifically, as shown in FIGS. 5A and 5B, the undulating surface 8 adopts an asymmetrical shape instead of a symmetrical shape for the concave portion 801 and the convex portion 802 . In particular, in the present embodiment, the concave portion 801 and the convex portion 802 are different in shape so that the minimum radius of curvature of the concave portion 801 is larger than the minimum radius of curvature of the convex portion 802 . In other words, the concave portions 801 of the undulating surface 8 form a smoother surface than the convex portions 802 . Furthermore, as described above, the undulating surface 8 does not have exactly the same continuous pattern, so the plurality of concave portions 801 and the plurality of convex portions 802 have non-uniform shapes. .

By adopting such asymmetrical shapes for the concave portion 801 and the convex portion 802, for example, even if a fine foreign matter X1 adheres to the undulating surface 8 as shown in FIG. Foreign matter X1 is easily discharged from recess 801 . As a result, foreign matter X1 such as dirt is less likely to accumulate on the undulating surface 8, and the undulating surface 8 has a remarkable effect that, for example, dirt such as fingerprints or dust is less likely to adhere (becomes easier to remove). . As a result, for example, changes in the electrical properties of the outlet device 1 due to contamination are less likely to occur. The shape of the undulating surface 8 as shown in FIGS. 5A and 5B is applicable to both the first undulating surface 81 and the second undulating surface 82 .

The functions of the undulating surface 8 as described above are enumerated below.

First, the undulating surface 8 formed on the front surface 501 is such that the above-described dirt is less likely to adhere (becomes easier to remove), less likely to be scratched, less likely to cause excessive light reflection, and more comfortable to the touch. Or it has a function such as anti-slip. In particular, since excessive light reflection is less likely to occur, for example, the difference in appearance between the outlet device 1 and the mounting object 3 (such as a wall) around the outlet device 1 is reduced, and the outlet device 1 is installed. It becomes easy to adapt to the object 3 (wall etc.). Moreover, the undulating surface 8 improves the texture in terms of appearance and touch, and produces a high-class feeling. As a result, even when the function of the outlet device 1 is installed everywhere in the room, for example, the presence of the outlet device 1 is not overemphasized, and there is an advantage that the atmosphere in the room is less likely to be disturbed. Furthermore, the undulating surface 8 can also have a cushioning function that, for example, when a relatively hard object collides with the front surface 501, the protrusions 802 are crushed to reduce the impact of the collision.

In addition, the undulating surface 8 formed on the outer peripheral surface 502 is less likely to be soiled, less likely to be scratched, less likely to cause excessive light reflection, more comfortable to touch, anti-slip, or In addition to the function of cushioning, it has the function of reducing frictional resistance. That is, when the undulating surface 8 slides on the mating member, the tip of the projection 802 comes into contact with the mating member, and the contact area with the mating member is smaller than that of the flat surface. As a result, the frictional resistance with the mating member is reduced. Particularly, in this embodiment, when the outlet system 10 is attached to the mounting object 3 , the outlet device 1 is combined with the outlet plate 4 so that the front surface 501 is exposed through the window hole 401 of the outlet plate 4 . At this time, since the outer peripheral surface 502 of the outlet device 1 slides against the inner peripheral surface of the window hole 401 in the outlet plate 4 , the undulating surface 8 reduces the frictional resistance between the outlet plate 4 and the outlet device 1 . reduction can be achieved.

Similarly, the undulating surface 8 formed on the inner peripheral surface 71 (tapered surface 701) of the insertion port 7 is also less likely to be stained, scratched, or excessively reflected. In addition to the anti-slip or cushioning function that improves the feeling of touch, it has the function of reducing frictional resistance. In particular, on the inner peripheral surface 71 of the receptacle 7, when the plug 2 is inserted into or removed from the receptacle device 1, the insertion piece 21 of the plug 2 slides. 2 (insertion piece 21) and the outlet device 1 can be reduced in frictional resistance.

In addition, the undulating surface 8 formed on the outlet plate 4 also has the function of preventing dirt from adhering to it, preventing it from being scratched, preventing excessive light reflection from occurring, improving the feeling of touch, preventing slippage, and providing cushioning. have. In particular, since the outlet plate 4 is positioned around the front surface 501 of the outlet device 1, by matching the texture with the front surface 501 of the outlet device 1, the appearance of the outlet system 10 is less likely to cause discomfort.

As described above, the outlet device 1 according to the present embodiment has the advantage that various functions can be provided to the outlet device 1 without adding a separate member such as an outlet cover to the outlet device 1. .

(3) Manufacturing Method Hereinafter, a manufacturing method of the outlet device 1 according to the present embodiment will be described with reference to FIGS. 6A to 6C.

The method for manufacturing the socket device 1 includes a molding step for molding the housing 5 . In this manufacturing method, in the molding process, the uneven surface 8 is formed by transferring the uneven shape of the transfer surface M11 to the front surface 501 of the housing 5 using the mold M1 having the uneven shape on the transfer surface M11.

That is, the cover 51 and the body 52 that constitute the housing 5 are produced by resin molding using a mold M1, as shown in FIG. 6A. In this embodiment, as an example, compression molding is employed in the molding process. In other words, in the molding process, the housing 5 (the cover 51 and the body 52) is produced by putting a molding material (resin material) into the cavity of the heated mold M1, pressing it with a compression molding machine, and hardening it.

Here, when the resin material is cured, the mold M1 is separated from the housing 5 (cover 51 in this case) by moving the transfer surface M11 of the mold M1 away from the front surface 501 as shown in FIG. 6B. "Releasing" is performed to allow the As shown in FIG. 6C, the transfer surface M11 has an uneven shape. The uneven shape on the transfer surface M11 of the mold M1 is formed by, for example, a chemical treatment such as etching, or a physical treatment such as sandblasting or polishing without mirror finishing.

As described above, during compression molding, the uneven shape of the transfer surface M11 is transferred to the front surface 501 of the housing 5 (cover 51), and the undulating surface 8 is formed on the front surface 501. FIG. Thus, the undulating surface 8 is formed by texturing (embossing). The undulating surface 8 other than the front surface 501 is also formed by transferring the uneven shape of the transfer surface M11 of the mold M1 to the housing 5. As shown in FIG.

That is, in this embodiment, even if the housing 5 of the outlet device 1 is not painted (paintless), it is possible to realize a configuration in which the front surface 501 and the like are formed with the undulating surface 8 .

According to the manufacturing method of the outlet device 1 as described above, the undulating surface 8 can be integrally formed with the housing 5 when the housing 5 (the cover 51 and the body 52) is molded. Therefore, for example, compared to the case where the undulating surface 8 is formed on the front surface 501 of the housing 5 by sandblasting or the like after the housing 5 is molded, the number of steps can be reduced and the productivity is improved.

The undulating surface 8 can also be formed on the outlet plate 4 (decorative plate 41 and fixing plate 42 ) by the same manufacturing method as that for the housing 5 .

(4) Modifications Embodiment 1 is merely one of various embodiments of the present disclosure. Embodiment 1 can be modified in various ways according to design and the like, as long as the object of the present disclosure can be achieved. Each drawing described in this disclosure is a schematic drawing, and the ratio of the size and thickness of each component in each drawing does not necessarily reflect the actual dimensional ratio.

Modifications of the first embodiment are listed below. Modifications described below can be applied in combination as appropriate. In the following, configurations similar to those of the first embodiment are denoted by common reference numerals, and descriptions thereof are omitted as appropriate.

As a modification of the first embodiment, as shown in FIGS. 7A to 7C, the cross-sectional shape of the undulating surface 8, that is, the shape of the concave portions 801 and the convex portions 802 included in the undulating surface 8 can be changed as appropriate. In the example of FIG. 7A, the undulating surface 8A has a configuration in which a plurality of concave portions 801 having the same shape and a plurality of convex portions 802 having the same shape are regularly arranged so that the same pattern is strictly continuous. . That is, the undulating surface 8A has a strictly uniform shape. In addition, in the example of FIG. 7B, the undulating surface 8B adopts a symmetrical shape with respect to the concave portion 801 and the convex portion 802 . That is, in the undulating surface 8B, the minimum radius of curvature of the concave portion 801 and the minimum radius of curvature of the convex portion 802 are substantially the same. Further, in the example of FIG. 7C, the undulating surface 8C has different shapes between the concave portions 801 and the convex portions 802 so that the minimum radius of curvature of the concave portions 801 is smaller than the minimum radius of curvature of the convex portions 802. there is In other words, the convex portions 802 of the undulating surface 8C form a smoother surface than the concave portions 801. As shown in FIG.

Further, as a modification of Embodiment 1, as shown in FIGS. 8A to 8C, the range of the undulating surface 8 in the outlet device 1 or outlet system 10 can be changed as appropriate.

In the example of FIG. 8A, the undulating surface 8 is formed only on the outlet device 1 of the outlet system 10 . That is, in the example of FIG. 8A, the undulating surface 8 is not formed on the outlet plate 4 . Further, in the example of FIG. 8A , the front surface 501 of the outlet device 1 has counterbore portions 72 formed around the insertion openings 7 . The counterbore portion 72 is a depression formed in the front surface 501 so as to gradually deepen as it approaches the periphery of the insertion port 7 . Therefore, when the insertion piece 21 of the plug 2 is inserted into the insertion opening 7 , the insertion piece 21 is guided to the insertion opening 7 by the bottom surface of the counterbore portion 72 . In the example of FIG. 8A, the undulating surface 8 (second undulating surface 82) is also formed on the bottom surface of the counterbore portion 72. In the example of FIG.

In the example of FIG. 8B, the undulating surface 8 is formed only on the outlet device 1 of the outlet system 10 . Furthermore, in the example of FIG. 8B, the undulating surface 8 is formed not on the entire front surface 501 of the outlet device 1 but on the range excluding the outer peripheral portion of the front surface 501 . In other words, the undulating surface 8 is not formed on the outer peripheral portion of the front surface 501 .

In the example of FIG. 8C, the undulating surface 8 is formed only on the outlet device 1 of the outlet system 10 . Furthermore, in the example of FIG. 8C , the undulating surface 8 is not formed on the inner peripheral surface 71 of the receptacle 7 in the outlet device 1 .

Further, it is not essential that the undulating surface 8 is classified into the first undulating surface 81 and the second undulating surface 82 as in the first embodiment. That is, for example, the undulating surfaces 8 formed on the outlet device 1 and the outlet plate 4 may be unified into one type of undulating surface 8 . Alternatively, the undulating surfaces 8 formed on the outlet device 1 and the outlet plate 4 may be classified into three or more types.

Further, the outlet device 1 is not limited to having no grounding pole, and may be provided with a grounding pole. For example, it may be an outlet for AC 200V or DC. Furthermore, the socket device 1 is not limited to the A type plug 2 in which the insertion piece 21 is a blade, and may be for a B type or C type plug 2 in which the insertion piece 21 is a pin, for example. Further, the outlet device 1 is not limited to a two-port type outlet, and may be, for example, a three-port type outlet to which three plugs 2 can be connected at the same time, or may be an outlet having four or more ports. .

Further, the plug 2 connected to the outlet device 1 is not limited to the plug 2 provided at the tip of the cable of the load. may be

In addition, the outlet device 1 includes, for example, a switch that switches between an energized state and a non-energized state of the load, and a protection circuit that detects an abnormal current such as an overcurrent or an earth leakage current or overheating and cuts off the energization of the load. , may further comprise: Furthermore, the outlet device 1 may further include a sensor such as a human sensor or a function such as a timer.

Moreover, the outlet device 1 and the outlet system 10 are not limited to indoor use, and may be used in a specific space in an outdoor facility such as a park or ground. For outdoor use, the outlet device 1 preferably satisfies predetermined performances such as waterproofness (including rainproofness and dripproofness) and weather resistance.

Further, the outlet device 1 is not limited to an embedded wiring device. In other words, the outlet device 1 may be an “exposed” wiring device that is arranged entirely from the surface of the mounting object 3 such as a wall. In this case, the outlet device 1 is attached to the attachment object 3 using an exposed switch box instead of an embedded switch box. Further, the outlet device 1 may be attached to the attachment object 3 using an attachment member other than the switch box, such as a clamp. Furthermore, the outlet device 1 and the outlet system 10 do not necessarily need to be attached to the attachment object 3 such as a wall, and may not be attached to the attachment object 3 . Further, when the body 52 is exposed, the undulating surface 8 may be formed not only on the cover 51 but also on the body 52 .

Further, it is not an essential configuration of the outlet system 10 that at least part of the surface 411 of the outlet plate 4 of the outlet system 10 is the undulating surface 8 . That is, the surface 411 of the outlet plate 4 may not be the undulating surface 8 . Even in this case, since at least part of the front surface 501 of the outlet device 1 is the undulating surface 8, various functions can be imparted to the outlet device 1 without adding a separate member such as an outlet cover. There is an advantage.

Further, it is not essential for the outlet device 1 to have a substantially uniform pattern (that is, an uneven shape) as long as the undulating surface 8 is in the same plane. For example, the undulating surface 8 may be in the same plane or may have different patterns depending on the part. Alternatively, the undulating surface 8 may have a series of exactly the same pattern, such as a geometric pattern.

Further, it is not essential for the socket device 1 to have an isotropic pattern (that is, an uneven shape) as long as the undulating surface 8 is in the same plane. For example, the undulating surface 8 may have an anisotropic pattern that differs depending on the direction even within the same plane. Examples of this type of anisotropic pattern include wood grain tone, hairline tone, and the like.

Moreover, the mounting frame 43 does not have to be integrated with the outlet device 1 . That is, the outlet device 1 may be fixed to the mounting object 3 using the mounting frame 43 that is separate from the outlet device 1 . Furthermore, the mounting frame 43 is not limited to being made of metal, and may be made of resin, or may be configured by combining metal and resin.

Moreover, the housing 5 and the outlet plate 4 of the outlet device 1 are not limited to being unpainted (paintless), and at least a part of them may be painted.

Further, the outlet device 1 may have a locking mechanism that prevents the plug 2 from coming off. The lock mechanism prevents the insertion piece 21 of the plug 2 from coming off, for example, by rotating the plug 2 .

Further, the power supply from the outlet device 1 to the plug 2 is not an essential configuration of the power outlet device 1 , and power may be supplied from the plug 2 to the outlet device 1 . For example, when the power generator plug 2 is connected to the outlet device 1 , power is supplied from the power generator plug 2 to the outlet device 1 .

Further, the outlet device 1 may include a door body that can move between the closed position and the open position inside the receptacle 7 . The closed position is a position where the door covers the connection member 6, and the open position is a position where the door does not cover (exposes) the connection member 6. FIG.

Also, the method for manufacturing the outlet device 1 (and the outlet plate 4) is not limited to the method described in the first embodiment. For example, after the housing 5 is molded, the undulating surface 8 may be formed by subjecting the front surface 501 of the housing 5 and the like to surface treatment such as sandblasting.

(Embodiment 2)
An outlet device 1D according to the present embodiment differs from the outlet device 1 according to the first embodiment in that, as shown in FIG. 9, it is a single outlet type outlet. In the following, configurations similar to those of the first embodiment are denoted by common reference numerals, and descriptions thereof are omitted as appropriate.

That is, in this embodiment, the outlet device 1D has a pair of receptacles 7 corresponding to one plug 2 . The outlet device 1D also includes the housing 5 in this embodiment. The housing 5 has a cover 51 and a body 52 .

Here, a pair of first protrusions 512 are provided on both end surfaces (left end surface and right end surface) of the cover 51 in the left-right direction. Similarly, a pair of second protrusions 522 are provided on both end surfaces (left end surface and right end surface) of the body 52 in the left-right direction. In this embodiment, the body 52 and the cover 51 are mechanically coupled using the first projection 512 and the second projection 522 in an assembly frame different from the mounting frame 43 .

That is, in this embodiment, the assembly frame couples the body 52 and the cover 51 by being attached to the housing 5 so as to hold the first protrusion 512 and the second protrusion 522 from both sides in the front-rear direction. In other words, the assembly frame sandwiches the first protrusion 512 and the second protrusion 522 in the front-rear direction in a state in which the body 52 and the cover 51 are combined in the front-rear direction, thereby forming the first protrusion 512 and the second protrusion 522 . It prevents the protrusion 522 from being relatively separated. As a result, the body 52 and the cover 51 are prevented from opening, and the body 52 and the cover 51 are joined together.

Also in the outlet device 1D according to this embodiment, the undulating surface 8 is formed on at least a part of the front surface 501 and the outer peripheral surface 502 of the housing 5 (cover 51), as in the first embodiment. Furthermore, the undulating surface 8 is also formed on at least a portion of the inner peripheral surface 71 of the insertion port 7 . In other words, at least a portion of the front surface 501 of the housing 5 , the outer peripheral surface 502 and the inner peripheral surface 71 of the receptacle 7 are the undulating surfaces 8 .
