[0006] An outlet according to one aspect of the present disclosure comprises a body and a cover. The body houses terminals electrically connectable to a plug. The cover is coupled to the body and has a rectangular parallelepiped shape with an open face on the body side and a plug insertion surface on the face opposite to the body. The cover has a pair of assembly members. Each of the pair of assembly members includes a first portion and a second portion. The first portion projects outward in a first direction on the outer surfaces of each pair of opposing sides of four sides adjacent to the plug insertion surface. The second portion extends in a second direction from the first portion toward the body. The pair of assembly members are integrally formed with the cover, and the second portion has a recess. Each of the side faces of the body has a protrusion projecting in the first direction. The cover and the body are coupled by a snap-fit ​​structure in which the protrusion is inserted into the recess.

[0007] A wiring device system in another aspect of the present disclosure comprises the outlet and a mounting frame. The mounting frame can be attached to an object while holding the outlet. [Effects of the Invention]

[0010] Hereinafter, an outlet and a wiring device system equipped therewith, according to the embodiments, will be described in detail with reference to the drawings. However, the figures described in the following embodiments are schematic diagrams, and the dimensional ratios of the size of each component do not necessarily reflect the actual dimensional ratios. Furthermore, the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0011] (Embodiment) (1) Overview As shown in Figure 3 and other figures, the outlet 1 of this embodiment includes an outlet body 2 to which two plugs 300 can be attached and detached. Each plug 300 is equipped with a pair of plug blades 301 and a grounding pin 302.

[0012] As shown in Figures 1 to 4, the outlet 1 of this embodiment comprises a body 4 and a cover 3.

[0013] Body 4 houses the plug 300 and terminals 60 that can be electrically connected to it (see Figure 4).

[0014] The cover 3 is coupled to the body 4 to constitute the outlet main body 2. The cover 3 has a rectangular parallelepiped shape with the surface on the body 4 side open (see Figures 1 and 4). The insertion surface 3a for the insertion plug 300 is provided on the surface of the cover 3 opposite to the body 4 (see Figures 1 to 4).

[0015] The cover 3 has a pair of assembly members 30A, 30A (see Figures 6 to 7 and the like). Each of the pair of assembly members 30A, 30A includes a first portion 34 and a second portion 35.

[0016] As shown in Figures 6 to 7 and the like, the first portion 34 protrudes in a first direction toward the outside on the outer surface of each of a pair of side surfaces 3b, 3b that face each other among the four side surfaces adjacent to the insertion surface 3a. The first direction is the positive direction or the negative direction of the Y axis in Figures 6 to 7.

[0017] As shown in Figures 5 and 6 and the like, the second portion 35 extends from the first portion 34 in a second direction toward the body 4. The second direction is the negative direction of the X axis in Figures 5 and 6 and the like.

[0018] The pair of assembly members 30, 30 are formed integrally with the cover 3. As shown in Figure 4 and the like, the second portion 35 of the pair of assembly members 30, 30 is provided with a recess 36 in the first direction.

[0019] As shown in Figure 8 and the like, each of the two side surfaces 4b, 4b of the body 4 is provided with a protrusion 41 protruding in the first direction.

[0020] The cover 3 and the body 4 are coupled by a snap-fit structure in which the protrusion 41 is inserted into the recess 36.

[0021] In this case, if the assembly members for joining the body and the cover are provided on the inside of the side surface of the cover, the state of connection between the cover and the body cannot be visually confirmed. In contrast, in the outlet 1 of this embodiment, a pair of assembly members 30A, 30A for joining the body 4 and the cover 3 are provided on the outer surfaces of a pair of side surfaces 3b, 3b of the cover 3, so the state of connection between the cover 3 and the body 4 can be visually confirmed from the outside. The recess 36 is a through hole that penetrates the second portion 35.

[0022] Furthermore, if the assembly components are separate parts, the number of parts in the outlet increases. In contrast, in this embodiment, the outlet 1 has a pair of assembly components 30A, 30A integrally formed with the cover 3. This reduces the number of parts in the outlet 1. Moreover, in this embodiment, the outlet 1 has a snap-fit ​​structure, allowing the cover 3 and body 4 to be joined simply by overlapping the cover 3 onto the body 4. Therefore, according to this embodiment, the workability of assembling the outlet 1 can be improved.

[0023] Furthermore, the wiring device system A1 according to this embodiment (see Figure 3) comprises an outlet 1 and a mounting frame 200. The mounting frame 200 can be attached to an object while holding the outlet 1.

[0024] On the first end of the insertion surface 3a of the cover 3 in the longitudinal direction, there is a pair of plug blade insertion holes 31, 31 into which the pair of plug blades 301, 301 of the first insertion plug 300 are inserted, and a grounding pin insertion hole 32 into which the grounding pin 302 of the first insertion plug 300 is inserted (see Figure 2). On the second end of the insertion surface 3a of the cover 3 in the longitudinal direction, there is a pair of plug blade insertion holes 31, 31 into which the pair of plug blades 301, 301 of the second insertion plug 300 are inserted, and a grounding pin insertion hole 32 into which the grounding pin 302 of the second insertion plug 300 is inserted (see Figure 2).

[0025] Furthermore, the rear surface 4a of the body 4 is provided with a plurality of wire insertion holes (not shown). The plurality of wire insertion holes include holes into which a pair of power wires W1 and W2 and a ground wire W3 are inserted.

[0026] Here, the pair of power lines W1 and W2 are power supply wires. The pair of power lines W1 and W2 are, for example, wires for supplying AC power, and are wires that connect a branch breaker (not shown) housed in a distribution board (not shown) that distributes AC power to outlet 1. The grounding wire W3 is, for example, a wire that connects a grounding terminal provided in the distribution board to outlet 1.

[0027] In the following embodiment, the outlet 1 houses a terminal 60 (hereinafter also referred to as the "power connection terminal") in the outlet body 2, which includes a plurality of blade receiving members that receive the plug blades of the two plugs 300 described above, a plurality of terminal boards connected to the plurality of blade receiving members, a plurality of spring members that hold a plurality of electric wires between the plurality of terminal boards, and a plurality of release buttons. The components housed in the outlet body 2 will be described in more detail in "(2.1.3) Power Connection Terminal".

[0028] Furthermore, the mounting object to which the mounting frame 200 is attached is, for example, the wall of a residential or non-residential building. The mounting frame 200 is attached to the wall with the main body of the outlet 1, held by the mounting frame 200, inserted into a mounting hole (not shown) provided in the wall. In this way, the outlet 1 is attached to the wall via the mounting frame 200. Note that the mounting object is not limited to the wall of a residential or non-residential building, but may also be, for example, equipment installed inside or outside a building, or walls on moving objects such as railway cars, aircraft, or ships. Since the wiring device system A1 is equipped with the above-described outlet 1, it is possible to provide a wiring device system A1 equipped with an outlet 1 that can improve the workability of the assembly work.

[0029] (2) Details Hereinafter, the outlet 1 and the wiring device system A1 equipped therewith according to this embodiment will be described in detail with reference to Figures 1 to 8.

[0030] In the following description, the X-axis direction in Figure 1, etc., is defined as the front-to-back direction (depth direction), the Y-axis direction as the left-to-right direction, and the Z-axis direction as the up-to-down direction. Furthermore, the positive direction in the X-axis direction is defined as the front, the positive direction in the Y-axis direction as the right side, and the positive direction in the Z-axis direction as the top. In this embodiment, the shape of the outlet body 2 when viewed from the front is rectangular. The outlet body 2 is mounted to the object to be installed (wall) via the mounting frame 200 with its longitudinal direction parallel to the up-to-down direction and its short direction parallel to the left-to-right direction. However, these directions are just examples and are not intended to limit the direction in which the outlet 1 and wiring device system A1 are used. The outlet body 2 may also be mounted to the object to be installed (wall) via the mounting frame 200 with its longitudinal direction parallel to the left-to-right direction and its short direction parallel to the up-to-down direction. Note that the arrows indicating each direction in the drawings are for illustrative purposes only and do not represent actual objects. Furthermore, in the following, the rightward or leftward direction may be referred to as the "first direction." The backward direction may be referred to as the "second direction."

Each of the pair of plug blade insertion holes 31, 31 is formed in a shape that connects a rectangular hole into which a flat plug blade can be inserted and an oval-shaped hole into which a round pin-type plug blade can be inserted. Both flat plug blades and round pin-type plug blades can be inserted into each of the pair of plug blade insertion holes 31, 31. The grounding pin insertion hole 32 is provided on the first end side of the front surface 3a of the cover 3, in the center in the left-right direction.

[0036] Similarly, on the second end side (negative side of the Z-axis in Figure 7) in the longitudinal direction (Z-axis direction in Figure 7) of the front surface 3a of the cover 3, there is a pair of plug blade insertion holes 31, 31 into which a pair of plug blades 301, 301 are inserted, and a grounding pin insertion hole 32 into which a grounding pin 302 is inserted.

[0082] The first release button 81 is a molded product of an electrically insulating synthetic resin. The first release button 81 is positioned between the first spring members 71A and 71B. The first release button 81 is used to remove the power line W1 held between the first terminal plate 61 and the first spring members 71A and 71B, respectively.

[0083] The pair of second blade receiving members 52A and 52B are formed by bending a single sheet of conductive metal (for example, a copper alloy).

[0087] The second release button 82 is a molded product of an electrically insulating synthetic resin. The second release button 82 is positioned between the second spring members 72A and 72B. The second release button 82 is used to remove the power line W2, which is held between the second terminal plate 62 and the second spring members 72A and 72B, respectively.

[0088] The pair of third blade receiving members 53A and 53B are formed by bending a single sheet of conductive metal (e.g., copper alloy). The third blade receiving member 53A elastically holds the grounding pin 302 of the first plug 300, and the third blade receiving member 53B elastically holds the round-pin type grounding pin 302 of the second plug 300.

[0089] The third terminal plate 63 is integrally provided with each of the pair of third blade receiving members 53A and 53B. The third terminal plate 63 is positioned opposite each of the third spring members 73A and 73B.

The third release button 83 is used to remove the grounding wire W3, which is held between the third terminal plate 63 and the third spring members 73A and 73B, respectively.

[0093] In this way, the outlet 1 of this embodiment can be configured with six sets of quick-connect power connection terminals capable of connecting two pairs of power lines W1 and W2 and a grounding wire W3.

[0094] (2.2) Wiring device systems The wiring device system A1 according to this embodiment includes an outlet 1 and a mounting frame 200 (see Figure 3).

[0095] The mounting frame 200 is formed in a rectangular frame shape from, for example, an electrically insulating synthetic resin.

[0096] As shown in Figure 2, the mounting frame 200 is formed in a rectangular frame shape by a pair of first frame pieces 210 extending along the longitudinal direction (Z-axis direction in Figure 2) of the outlet body 2, and a pair of second frame pieces 220 connecting the ends of the pair of first frame pieces 210.

[0097] The mounting frame 200 has a rectangular opening 230 enclosed by a pair of first frame pieces 210 and a pair of second frame pieces 220 (see Figure 3). One outlet 1 is positioned longitudinally within the opening 230. Each of the pair of first frame pieces 210 is provided with three sets of two insertion grooves 211 into which four claw portions 38, provided on each of the left and right sides of the cover 3, are inserted.

[0098] Each of the pair of second frame pieces 220 is provided with an elongated hole 221 for inserting a screw member (not shown) for screw-fixing the mounting frame 200 to, for example, a switch box (not shown) embedded in a wall. Each of the pair of second frame pieces 220 is also provided with two round holes 222 for inserting a screw member (not shown), such as a tapping screw, for fixing the mounting frame 200 to a wall such as plasterboard.

[0099] The outlet body 2 is held in the mounting frame 200 with four claws 38 on each of the left and right sides of the cover 3 inserted into eight insertion grooves 211 on a pair of first frame pieces 210. Then, with the rear of the outlet body 2 held in the mounting frame 200 inserted into a recessed hole in the wall, the mounting frame 200 is fixed to the wall using screw members inserted into the elongated holes 221 or round holes 222 of the second frame piece 220. In this way, the outlet 1 is attached to an object to be mounted, such as a wall, via the mounting frame 200.

[0100] In this embodiment, the size of the outlet body 2 is designed to be a module size that allows one outlet body 2 to be mounted on a mounting frame 200 that can be attached to an object (e.g., a wall) while holding the outlet body 2. Six sets of quick-connect power connection terminals, to which the two pairs of power lines W1, W2 and the grounding wire W3 described above can be connected, are housed in the outlet body 2 of this module size.

[0101] (3) Operation Description An example of the assembly and installation work for the outlet 1 of this embodiment will be described.

[0102] (3.1) Housing of power connection terminals First, the user (e.g., a contractor) houses the power connection terminals in the first housing compartment R1, the second housing compartment R2, and the third housing compartment R3 of the body 4, as shown in Figure 1, etc. Specifically, the user houses a wire connection terminal in the first housing compartment R1 on the right side of the body 4, which includes a pair of first blade receiving members 51A, 51B, a first terminal plate 61, first spring members 71A, 71B, and a first release button 81. The user also houses a wire connection terminal in the second housing compartment R2 on the left side of the body 4, which includes a pair of second blade receiving members 52A, 52B, a second terminal plate 62, second spring members 72A, 72B, and a second release button 82. The user houses a wire connection terminal in the central third housing chamber R3 of the body 4, which includes a pair of third blade receiving members 53A, 53B, a third terminal plate 63, third spring members 73A, 73B, and a third release button 83.

[0103] (3.2) Joining the cover and body Next, the user connects the cover 3 to the body 4. Specifically, as shown in Figure 4, the user brings the cover 3 closer to the body 4 from the front. Then, the four second parts 35 of each of the assembly members 30A, 30A, 30B, and 30B come into contact with the eight protrusions 41 of the body 4. At this point, as described above, the second parts 35 are elastically deformable against lateral forces, so the second parts 35 are bent outward relative to the protrusions 41 of the body 4. As a result, the second parts 35 pass outside the protrusions 41 while still in contact with them, and the cover 3 comes even closer to the body 4. Then, when the eight protrusions 41 are inserted into the eight recesses 36, two of which are provided in each of the four second parts 35, the body 4 and the cover 3 are connected (see Figure 8).

[0104] In this embodiment, the assembly members 30A, 30A, 30B, and 30B are provided on the outer surfaces of the pair of sides 3b, 3b of the cover 3, so the user can visually confirm the connection between the cover 3 and the body 4. Furthermore, since the assembly members 30A, 30A, 30B, and 30B are integrally formed with the cover 3, the number of parts in the outlet 1 can be reduced.

[0105] Furthermore, the snap-fit ​​structure in which the protrusion 41 of the body 4 is inserted into the recess 36 allows the user to join the cover 3 and the body 4 simply by placing the cover 3 on top of the body 4.

[0106] Furthermore, in this embodiment, since the outlet 1 has assembly members 30A, 30A, 30B, 30B on the outer surfaces of the left and right pair of sides 3b, 3b of the cover 3, there is no need to change the size of the cover 3 (the area of ​​the front surface 3a) from the conventional size. As a result, the outlet 1 can be assembled using a body 4 of the same size as in the conventional model.

[0107] Furthermore, since the assembly members 30A, 30A, 30B, and 30B are made of thermoplastic resin, they are easily elastically deformed. This makes it easier to connect the cover 3 and the body 4 using a snap-fit ​​structure.

[0108] Furthermore, since each of the assembly members 30A, 30A, 30B, and 30B is provided with two recesses 36, 36, the cover 3 can be firmly connected to the body 4.

[0109] Furthermore, since a rib 37 is provided between the two recesses 36, 36, the strength and flexibility necessary for joining the cover 3 and the body 4 can be ensured.

[0110] Furthermore, in this embodiment, the first pair of assembly members 30A, 30A are provided on the upper end side in the longitudinal direction. The second pair of assembly members 30B, 30B are provided on the lower end side in the longitudinal direction. This allows for a stronger connection between the cover 3 and the body 4 compared to the case where the pair of assembly members 30, 30 are provided at the center in the longitudinal direction.

[0111] (3.3) Installation of electrical outlets Next, the user attaches the outlet body 2 to the mounting frame 200. Specifically, the user attaches the outlet body 2 to the mounting frame 200 with the four claws 38 provided on each of the left and right sides 3b, 3b of the cover 3 inserted into the eight insertion grooves 211 provided on the pair of first frame pieces 210. In this case, as shown in Figure 2, the claws 38 protrude further outward from the first part 34 of the assembly member 30, so the length of the claws 38 can be shortened compared to a configuration in which the claws are directly provided on the outer surface of the cover 3. This makes it less likely for the strength of the claws 38 to decrease. This makes it easier for the user to attach the cover 3 to the mounting frame 200.

[0112] Then, with the outlet body 2 attached to the mounting frame 200, the user inserts a pair of power wires W1, W2 and a ground wire W3 through the multiple wire insertion holes provided on the rear surface 4a of the body 4, connecting the pair of power wires W1, W2 and ground wire W3 to the outlet body 2. Then, with the rear of the outlet body 2 held by the mounting frame 200 inserted into a recessed hole provided in the wall, the user fixes the mounting frame 200 to the wall using screw members inserted into the elongated holes 221 or round holes 222 of the second frame piece 220. In this way, the outlet 1 is attached to a mounting object such as a wall via the mounting frame 200.

[0113] Furthermore, as shown in Figures 2 and 7, the first part 34 is provided with a groove 39 between the two claw portions 38, 38. The groove 39 is recessed inward relative to the surface of the first part 34. This makes it easier for the user to remove the outlet 1 from the mounting frame 200 by using a pointed tool such as a screwdriver.

[0114] (4) Variations The above embodiments are merely one of many embodiments of this disclosure. The above embodiments can be modified in various ways depending on the design, etc., as long as they achieve the objectives of this disclosure.

[0115] Although the outlet 1 in the above embodiment is configured to allow connection of two plugs 300 (see Figure 3), it may also be configured to allow connection of one plug 300.

[0116] Furthermore, in the above embodiment, the outlet 1 has an outlet body 2 with dimensions of 3 modules, and one outlet body 2 can be mounted on the mounting frame 200 (see Figure 2), but the outlet body 2 may also have dimensions of 1 module.

[0117] Figure 9 is a perspective view of the modified outlet 1A of the present disclosure before it is attached to the mounting frame 200. As shown in Figure 9, the modified outlet 1A is configured to be able to connect to one plug 300. Specifically, the insertion surface 3a of the cover 3 is provided with a pair of plug blade insertion holes 31, 31 into which a pair of plug blades 301, 301 of the plug 300 are inserted, and a grounding pin insertion hole 32 into which a grounding pin 302 is inserted.

[0118] The modified outlet 1A has a pair of assembly members 30, 30. More specifically, the insertion surface 3a of the cover 3 is rectangular in shape. The pair of assembly members 30, 30 are provided on each of the two opposing left and right sides 3b, 3b of the four sides adjacent to the insertion surface 3a. In other words, the pair of assembly members 30, 30 are provided on each of the two sides 3b, 3b adjacent to the short side of the insertion surface 3a.

[0119] Each of the pair of assembly members 30, 30 includes a first part 34 and a second part 35.

[0120] The first portion 34 protrudes outward in a first direction (the negative direction of the Y-axis in Figure 9) on the outer surfaces of each of the two opposing left and right side surfaces 3b, 3b, which are among the four side surfaces adjacent to the insertion surface 3a.

[0121] As shown in Figure 9, the second part 35 extends in a second direction (the negative direction of the X-axis in Figure 9) from the first part 34 toward the body 4.

[0122] The pair of assembly members 30, 30 are integrally formed with the cover 3. Each of the second portion 35 of the pair of assembly members 30, 30 is provided with two recesses 36. More specifically, the two recesses 36, 36 are arranged side by side in the vertical direction (Z-axis direction in Figure 9).

[0123] Each of the two sides 4b of the body 4 is provided with two protrusions 41. The two protrusions 41 project in the first direction (the negative direction of the Y-axis in Figure 9).

[0124] In the modified outlet 1A, the cover 3 and body 4 are joined by a snap-fit ​​structure in which four protrusions 41 are inserted into four recesses 36. According to the modified outlet 1A, the workability of the assembly process can be improved, similar to the above embodiment.

[0125] Furthermore, in the modified outlet 1A, the cover 3 and body 4 are joined by a pair of assembly members 30, 30, but the area of ​​the insertion surface 3a is smaller than that of the outlet 1 in the above embodiment. Moreover, as shown in Figure 9, the pair of assembly members 30, 30 are provided on each of the pair of side surfaces 3b, 3b adjacent to the short side of the insertion surface 3a, so the bonding strength of the outlet body 2 of the modified outlet 1A is not reduced.

[0126] Furthermore, the first portion 34 is provided with claw portions 38. The claw portions 38 protrude further outward from the first portion 34 (in the negative direction of the Y axis in Figure 9). Two claw portions 38 are provided at both ends of the first portion 34 in the longitudinal direction (in the Z axis direction in Figure 9). The two claw portions 38 are provided at a predetermined interval along the vertical direction (in the Z axis direction in Figure 9).

[0127] In the modified outlet 1A, the size of the outlet body 2 is the same as a single module. This allows three outlet bodies 2 to be mounted on the mounting frame 200. When mounting the modified outlet 1A to the mounting frame 200, the outlet body 2 is held in the mounting frame 200 with two claws 38, each provided on the left and right sides 3b, 3b of the cover 3, inserted into two insertion grooves 211 provided on a pair of first frame pieces 210. Then, with the rear of the outlet body 2 held in the mounting frame 200 inserted into a recessed hole provided in the wall, the mounting frame 200 is fixed to the wall using a screw member inserted into the elongated hole 221 or round hole 222 of the second frame piece 220. In this way, the outlet 1A is mounted to the wall via the mounting frame 200, similar to the embodiment described above.

[0128] In this configuration, as shown in Figure 9, the claw portion 38 protrudes further outward from the first portion 34 of the assembly member 30, allowing the length of the claw portion 38 to be shortened compared to a configuration where the claw portion is directly provided on the outer surface of the cover 3. This makes it less likely for the strength of the claw portion 38 to decrease. As a result, similar to the above embodiment, it becomes easier for the user to attach the cover 3 to the mounting frame 200.

[0129] Furthermore, a rib 37 is provided in the second portion 35. The rib 37 is provided between the two recesses 36, 36 along the rear direction (X-axis direction in Figure 9). The longitudinal direction of the rib 37 is along the front-rear direction. This ensures the strength and flexibility necessary for joining the cover 3 and the body 4, similar to the embodiment described above.

[0130] Furthermore, in the outlet 1 of the above embodiment and the modified outlet 1A, a grounding pin insertion hole 32 for inserting a grounding pin 302 is provided on the insertion surface 3a of the cover 3 (see Figures 3 and 9), but the grounding pin insertion hole 32 is not required. In other words, the grounding pin insertion hole 32 is not essential in the outlet 1 of the above embodiment and the modified outlet 1A.

[0131] (summary) Based on the embodiments described above, the following aspects are disclosed.

[0132] A first embodiment of the outlet (1, 1A) comprises a body (4) and a cover (3). The body (4) houses terminals (60) that can be electrically connected to a plug (300). The cover (3) is coupled to the body (4) and has a rectangular parallelepiped shape with an open face on the body (4) side, and a plug insertion surface (3a) is provided on the face opposite to the body (4). The cover (3) has a pair of assembly members (30, 30). Each of the pair of assembly members (30, 30) includes a first portion (34) and a second portion (35). The first portion (34) protrudes outward in a first direction on the outer surfaces of each of the four sides adjacent to the insertion surface (3a), specifically on a pair of opposing sides (3b, 3b). The second portion (35) extends in a second direction from the first portion (34) toward the body (4). A pair of assembly members (30, 30) are integrally formed with the cover (3), and a recess (36) is provided in the second portion (35). Each of the two sides (4b, 4b) of the body (4) is provided with a protrusion (41) projecting in the first direction. The cover (3) and the body (4) are joined by a snap-fit ​​structure in which the protrusion (41) is inserted into the recess (36).

[0133] In this embodiment, a pair of assembly members (30, 30) for joining the cover (3) and the body (4) are provided on the outer surface of the side (3b, 3b) of the cover (3). The assembly work can be performed while visually checking the state of the connection between the cover (3) and the body (4). Since the pair of assembly members (30, 30) are integrally formed with the cover (3), the number of parts in the outlet (1, 1A) can be reduced. Due to the snap-fit ​​structure, the cover (3) and the body (4) can be joined simply by overlapping the cover (3) onto the body (4). This improves the workability of the assembly work of the outlet (1, 1A).

[0134] In the second embodiment of the outlet (1, 1A), the material of the pair of assembly members (30, 30) is a thermoplastic resin, as in the first embodiment.

[0135] According to this embodiment, the assembly member (30) becomes more elastically deformable, making it easier to connect the cover (3) and the body (4) using the snap-fit ​​structure. This improves the workability of assembling the outlet (1).

[0136] The outlet (1, 1A) of the third embodiment, in the first or second embodiment, has a second portion (35) provided with two recesses (36) and a rib (37). The rib (37) is provided between the two recesses (36). The rib (37) is provided along the second direction.

[0137] According to this embodiment, since two recesses (36, 36) are provided in the second portion (35) of the assembly member (30), the cover (3) can be more firmly joined to the body (4). Furthermore, since a rib (37) is provided between the two recesses (36, 36), the assembly member (30) can be made to have the strength and flexibility necessary for joining the cover (3) and the body (4). This can further improve the workability of the assembly work of the outlet (1).

[0138] In the fourth embodiment of the outlet (1, 1A), a claw portion (38) is provided on the first part (34) in any one of the first to third embodiments. The claw portion (38) further protrudes in the first direction from the first part (34).

[0139] In this embodiment, since the claw portion (38) protrudes further outward from the first portion (34) of the assembly member (30), the length of the claw portion (38) can be shortened compared to a configuration in which the claw portion (38) is directly provided on the outer surface of the cover (3). This makes it less likely for the strength of the claw portion (38) to decrease. It becomes easier to attach the cover (3) to the mounting frame (200). The workability of the outlet (1, 1A) installation work can be improved.

[0140] In the fifth embodiment of the outlet (1, 1A), in the fourth embodiment, two claw portions (38) are provided along the third direction at a predetermined interval. The third direction is perpendicular to the first direction and the second direction, respectively, on each of the pair of sides (3b, 3b). A groove portion (39) is provided in the first portion (34). The groove portion (39) is provided between the two claw portions (38, 38).

[0141] In this embodiment, a groove (39) is provided between the two claw portions (38, 38), making it easier to remove the cover (3) from the mounting frame (200) by using a pointed tool such as a screwdriver. This improves the work efficiency of removing the outlet (1).

[0142] The outlet (1) of the sixth embodiment further has a cover (3) in any one of the first to fifth embodiments that includes a plurality of first plug blade insertion holes (31, 31) and a plurality of second plug blade insertion holes (31, 31). The plurality of first plug blade insertion holes (31, 31) are provided on the first end side in the longitudinal direction of the insertion surface (3a). The plurality of second plug blade insertion holes (31, 31) are provided on the second end side in the longitudinal direction of the insertion surface (3a). A pair of assembly members (30A, 30A, 30B, 30B) are provided on the first end side and the second end side in the longitudinal direction of each of the two sides (3b, 3b). The pair of assembly members (30A, 30A) provided on the first end side overlap with the multiple first plug blade insertion holes (31, 31) and the insertion surface (3a) in the short direction when viewed from above. The pair of assembly members (30B, 30B) provided on the second end side overlap with the multiple second plug blade insertion holes (31, 31) and the insertion surface (3a) in the short direction when viewed from above.

[0143] In this embodiment, in a cover (3) having two sets of plug blade insertion holes (31, 31) on both ends in the longitudinal direction of the insertion surface (3a) of the plug (300), two pairs of assembly members (30A, 30A, 30B, 30B) are provided on both ends in the longitudinal direction. This allows for a stronger connection between the cover (3) and the body (4) compared to the case where a pair of assembly members (30, 30) are provided in the center in the longitudinal direction. This further improves the workability of the assembly work of the outlet (1).

[0144] The configurations relating to the second to sixth aspects are not essential for the outlet (1, 1A) and can be omitted as appropriate.

[0145] The wiring device system (A1) of the seventh embodiment comprises one outlet (1, 1A) of any of the first to sixth embodiments, and a mounting frame (200) that can be attached to an object while holding the outlet (1, 1A).

[0146] According to this embodiment, a wiring device system (A1) equipped with an outlet (1, 1A) that can improve the workability of assembly work can be provided. [Explanation of Symbols]
