[0015] (Embodiment) <Configuration> First, the display structure 5 and the wiring device 1 will be described with reference to (a) and (b) of Figs. 1 to 3.

[0016] Fig. 1 is a perspective view showing the appearance of a wiring device 1 according to an embodiment. Fig. 2 is an exploded perspective view showing the wiring device 1 according to an embodiment. Fig. 3 is a cross-sectional view showing the wiring device 1 on the AA line of Fig. 1. Fig. 3(a) shows the state before the electric wire 90 is inserted into the insertion hole 112, and Fig. 3(b) shows the state after the electric wire 90 has been inserted into the insertion hole 112 and the electric wire 90 and the terminal 20 are electrically connected.

[0017] As shown in Figs. 1 and 2, the wiring device 1 is a connection device that supplies or cuts off power to equipment systems, such as lighting devices and air blowers, installed in a facility. The wiring device 1 is embedded in a structure such as a ceiling, wall, or floor. The wiring device 1 is, for example, an outlet or a switch. The wiring device 1 is formed in the shape of a vertically long rectangular parallelepiped.

[0018] When an operator connects the electric wire 90 to the wiring fixture 1, the electric wire 90 is inserted into the insertion hole 112 of the wiring fixture 1. As a result, the electric wire 90 is electrically connected to the terminal 20 of the wiring fixture 1.

[0019] The wiring device 1 will be described in more detail below.

[0020] The wiring device 1 includes a terminal structure, a housing 10, a display structure 5, and a cover 9.

[0021] The terminal structure is accommodated inside the housing 10 so as to be electrically connectable with an electric wire 90 inserted through an insertion hole 112 formed in the housing 10. The terminal structure is accommodated in the housing 10 by a first housing 110 of the housing 10 and a second housing 120 of the housing 10 arranged on the positive side of the housing 10 in the Z-axis direction.

[0022] Specifically, the terminal structure includes a terminal 20 and a locking spring 30 .

[0023] Terminal 20 is a quick-connect terminal capable of accommodating locking spring 30 of display structure 5 therein. Terminal 20 is housed in first housing 110 and has terminal plate 21 electrically connected to electric wire 90, opposing plate 22 arranged on the opposite side of terminal plate 21 with locking spring 30 in between, and connection portion 23 connecting terminal plate 21 and opposing plate 22. When electric wire 90 is inserted through insertion hole 112 of housing 10, terminal 20 electrically connects electric wire 90 pressed against locking spring 30 to terminal plate 21.

[0024] The locking spring 30 makes elastic contact with the electric wire 90 inserted through the insertion hole 112, thereby electrically connecting the electric wire 90 and the terminal 20. The locking spring 30 is disposed so as to face the insertion hole 112.

[0025] As shown in Figures 2 and 3(a), the locking spring 30 has an S-shaped pressing piece 32 when viewed along the Y-axis direction, a U-shaped or V-shaped locking piece 31 arranged in a position facing the opening surface of the insertion hole 112, and a strip-shaped central piece 33 that connects the locking piece 31 and the pressing piece 32 and is held by the opposing plate 22 of the terminal 20. The locking piece 31 is arranged so as to be closer to the opening surface of the insertion hole 112 than the pressing piece 32. The locking piece 31 is exposed from the insertion hole 112. The locking piece 31 and the pressing piece 32 are arranged so as to face the terminal plate 21 of the terminal 20. The locking piece 31 and the pressing piece 32 can press the terminal plate 21 of the terminal 20 via the electric wire 90.

[0026] The housing 10 is a housing formed with an accommodation chamber S for accommodating the terminal structure, the contact body 60, and the elastic member 50, and is partially embedded in a building. The housing 10 is a housing for a socket or a housing for a switch.

[0027] The housing 10 includes a first housing 110 and a second housing 120 .

[0028] The first housing 110 is cubic and opens on the positive Z-axis side. The first housing 110 is substantially parallel to the XY plane and has a side wall 113 disposed on the negative Z-axis side, and multiple peripheral walls 114 rising from the outer peripheral edge of the side wall 113 in the positive Z-axis direction.

[0029] The side wall 113 is formed with an insertion hole 112 for inserting and removing the electric wire 90. The electric wire 90 is inserted into the insertion hole 112 to be electrically connected to the terminal 20. The insertion hole 112 communicates with the accommodating chamber S that accommodates the terminal structure and the like, so that the electric wire 90 inserted into the insertion hole 112 is electrically connected to the terminal structure. In this embodiment, a plurality of insertion holes 112 are formed in the side wall 113 of the first housing 110, but only one insertion hole 112 may be formed in the first housing 110.

[0030] A support portion is formed in the receiving chamber S of the first housing 110. The support portion supports the terminal structure, the contact body 60, and the elastic member 50 housed in the housing 10.

[0031] The second housing 120 is disposed on the positive Z-axis direction side of the first housing 110, and is connected to the side wall 113 of the first housing 110. Specifically, a portion of the second housing 120 is connected to the side wall 113 of the first housing 110 so as to protrude in the positive X-axis direction beyond the peripheral wall 114 disposed on the positive X-axis direction side of the first housing 110.

[0032] Second housing 120 is formed with guide groove portions 121 and openings 122. In this embodiment, since first housing 110 is formed with a plurality of insertion holes 112, second housing 120 is also formed with a plurality of guide groove portions 121. In other words, the plurality of insertion holes 112 and the plurality of guide groove portions 121 correspond one-to-one.

[0033] The guide groove portion 121 is formed on the surface of the second housing 120 on the positive side of the Z axis, and extends in the X axis direction. The guide groove portion 121 accommodates the contact body 60 and the elastic member 50, and supports the contact body 60 so that the contact body 60 can move. In this embodiment, a plurality of guide groove portions 121 is formed in the second housing 120, and therefore a plurality of contact bodies 60 and a plurality of elastic members 50 are arranged in the second housing 120 so as to correspond one-to-one with the plurality of guide groove portions 121.

[0034] The opening 122 communicates with the guide groove portion 121. The opening 122 is a part of the second housing 120 that protrudes in the positive direction of the X axis beyond the peripheral wall 114, and is formed on the surface of the second housing 120 on the negative direction side of the Z axis. The opening 122 opens in the same direction as the opening of the insertion hole 112. In other words, the opening 122 opens in the negative direction of the Z axis.

[0035] In this embodiment, since a plurality of guide groove portions 121 are formed in second housing 120, a plurality of openings 122 are also formed in second housing 120. In other words, the plurality of guide groove portions 121 and the plurality of openings 122 correspond one-to-one.

[0036] The display structure 5 is disposed inside the housing 10. The display structure 5 has a contact body 60 and an elastic member 50.

[0037] The contact body 60 has a display member 60a. The display member 60a has a columnar shape that is long in the X-axis direction. The display member 60a is disposed in the guide groove portion 121 so as to be movable in the X-axis direction.

[0038] A first inclined surface 61 is formed on the end of the display member 60a on the negative X-axis direction side. The first inclined surface 61 is located deep within the insertion hole 112, that is, on the positive Z-axis side of the gap K between the locking spring 30 (the locking piece 31 and the pressing piece 32 in FIG. 2 ) and the terminal board 21. That is, the opening of the insertion hole 112, the gap K, and the first inclined surface 61 are arranged side by side in this order along the positive Z-axis direction. When the wiring device 1 is viewed in cross section as shown in FIGS. 3(a) and 3(b), the first inclined surface 61 is inclined upward toward the negative X-axis direction. Therefore, the tip of the electric wire 90 inserted into the insertion hole 112 can pass through the gap K and contact the first inclined surface 61, thereby pressing the first inclined surface 61 in the positive Z-axis direction. At this time, as the tip of the electric wire 90 slides along the first inclined surface 61, the display member 60a moves in the positive X-axis direction while being guided by the guide groove portion 121, elastically deforming the elastic member 50. That is, the display member 60a moves in a direction substantially perpendicular to the insertion direction of the electric wire 90 inserted into the insertion hole 112. Then, a part of the display member 60a is exposed from the opening 122.

[0039] An indicator pattern 63 is provided on the end of the indicator member 60a on the positive X-axis direction side. When the indicator member 60a moves in the positive X-axis direction while being guided by the guide groove portion 121, the indicator pattern 63 is exposed from the opening 122. The indicator pattern 63 is provided on the surface of the indicator member 60a on the negative Z-axis direction side so as to be exposed from the opening 122. The indicator pattern 63 indicates that the electric wire 90 is electrically connected to the terminal 20. In this embodiment, the indicator pattern 63 may be colored in a color different from the material color of the indicator member 60a, or may be a pattern or letters.

[0040] The elastic member 50 is a coil spring. The elastic member 50 is disposed between the housing 10 and the display member 60a so as to extend along the X-axis direction. Specifically, one end of the elastic member 50 is supported by a support recess 66 formed at the end of the display member 60a on the positive side of the X-axis, and the other end of the elastic member 50 is supported by the end of the guide groove 121 on the positive side of the X-axis. The elastic member 50 biases the display member 60a so that the opening of the insertion hole 112, the gap K, and the first inclined surface 61 are aligned in this order along the positive direction of the Z-axis. In other words, when the electric wire 90 is not inserted into the insertion hole 112 and pressing against the display member 60a, the elastic member 50 biases the display member 60a so that the display pattern 63 of the display member 60a is not exposed from the opening 122. When the tip of the electric wire 90 inserted into the insertion hole 112 presses the display member 60a and the display member 60a moves in the positive direction of the X-axis, the elastic member 50 is pressed against the housing 10 by the display member 60a and elastically deforms.

[0041] The cover 9 has a flat rectangular shape and is disposed on the front surface (the surface on the positive Z-axis direction side) of the wiring device 1. The cover 9 is fixed to the second housing 120 so as to cover the second housing 120.

[0042] Next, a case where the electric wire 90 is electrically connected to the wiring fixture 1 in this embodiment will be described.

[0043] First, in the wiring device 1, the electric wire 90 can be inserted into the gap K between the locking piece 31 and the pressing piece 32 and the terminal board 21 so as to correspond to the insertion hole 112. When an operator inserts the electric wire 90 through the insertion hole 112, the electric wire 90 passes through the gap K, and the tip of the electric wire 90 comes into contact with the first inclined surface 61 of the display member 60a.

[0044] The tip of the electric wire 90 that comes into contact with the first inclined surface 61 presses the first inclined surface 61 in the positive direction of the Z axis. Then, as the tip of the electric wire 90 slides along the first inclined surface 61, the pressing force of the electric wire 90 on the display member 60a in the positive direction of the Z axis is converted into a moving force in the positive direction of the X axis, and the display member 60a moves in the positive direction of the X axis. The display member 60a moves in the positive direction of the X axis while being guided by the guide groove portion 121 while elastically deforming the elastic member 50. In other words, the display member 60a is pressed by the electric wire 90 inserted into the insertion hole 112, elastically deforming the elastic member 50, and can move so that the opening area of ​​the opening 122 becomes smaller in accordance with the elastic deformation of the elastic member 50.

[0045] Since the indicator pattern 63 is provided on the end of the indicator member 60a on the positive X-axis direction side and on the surface on the negative Z-axis direction side, the indicator pattern 63 is exposed from the opening 122 of the second housing 120. Since it is indicated that the electric wire 90 is electrically connected to the terminal 20, the worker can recognize that the electric wire 90 is electrically connected to the terminal 20. In this way, the electric wire 90 is sandwiched between the terminal 20 and the locking spring 30, so that the electric wire 90 is electrically connected to the terminal 20 and fixed to the terminal structure. Then, the worker can complete the installation of the electric wire 90 into the wiring device 1.

[0046] Furthermore, when the electric wire 90 is removed from the insertion hole 112, the elastic member 50 presses the display member 60a in the negative X-axis direction, causing the display member 60a to move in the negative X-axis direction. As a result, the display member 60a is no longer exposed from the opening 122.

[0047] Next, in the display structure 5 and the wiring device 1a according to the present embodiment, the contact body 160 may have a display member 60a and a wire receiving member 60b.

[0048] In this case, the display structure 5 and the wiring device 1a will be described with reference to (a) and (b) of Figure 4. Figure 4 is a cross-sectional view showing the wiring device 1a in which the display member 60a is exposed from the opening 122 by the electric wire receiving member 60b. (a) of Figure 4 shows the state before the electric wire 90 is inserted into the insertion hole 112, and (b) of Figure 4 shows the state after the electric wire 90 has been inserted into the insertion hole 112 and the electric wire 90 and the terminal 20 are electrically connected.

[0049] The same configurations and functions as those of the display structure 5 and wiring device 1a described above are denoted by the same reference numerals as above, and the description thereof will be omitted as appropriate.

[0050] The wire receiving member 60b is disposed inside the housing 10. Specifically, the wire receiving member 60b is disposed inside the first housing 110 and at the back of the insertion hole 112, that is, disposed on the positive Z-axis direction side of the gap K. In other words, the opening of the insertion hole 112, the gap K, and the wire receiving member 60b are disposed side by side in this order along the positive Z-axis direction. Therefore, when the wire 90 is inserted into the insertion hole 112, the end face of the wire receiving member 60b on the negative Z-axis side comes into contact with the tip of the wire 90 and can be pressed by the wire 90 in the positive Z-axis direction and moved.

[0051] Specifically, the display member 60a is formed with a first inclined surface 61. Furthermore, a second inclined surface 62 is formed at the end of the wire receiving member 60b on the positive side of the Z axis, which contacts the first inclined surface 61 of the display member 60a and is pressed by the first inclined surface 61. When the wiring device 1a is viewed in cross section as shown in FIGS. 4(a) and 4(b), the first inclined surface 61 and the second inclined surface 62 are inclined upward toward the negative direction of the X axis. Therefore, the tip of the wire 90 inserted into the insertion hole 112 can pass through the gap K between the locking piece 31 and the pressing piece 32 and the terminal board 21, come into contact with the end of the wire receiving member 60b on the negative side of the Z axis, and press the wire receiving member 60b in the positive direction of the Z axis. Then, as the wire receiving member 60b moves in the positive direction of the Z axis (the insertion direction of the wire 90), the second inclined surface 62 of the wire receiving member 60b presses against the first inclined surface 61 of the display member 60a, and the first inclined surface 61 and the second inclined surface 62 slide against each other. The pressing force of the wire 90 on the wire receiving member 60b in the positive direction of the Z axis is converted into a moving force of the display member 60a in the positive direction of the X axis. Therefore, the display member 60a moves in the positive direction of the X axis while being guided by the guide groove portion 121 while elastically deforming the elastic member 50. In other words, the wire receiving member 60b is pressed by the wire 90 inserted into the insertion hole 112, causing the elastic member 50 to elastically deform, and the display member 60a can move so that the opening area of ​​the opening 122 becomes smaller in accordance with the elastic deformation of the elastic member 50.

[0052] Since the indicator pattern 63 is provided on the end of the indicator member 60a on the positive X-axis direction side and on the surface on the negative Z-axis direction side, the indicator pattern 63 is exposed from the opening 122 of the second housing 120. Since it is indicated that the electric wire 90 is electrically connected to the terminal 20, the worker can recognize that the electric wire 90 is electrically connected to the terminal 20. Then, the worker can complete the attachment of the electric wire 90 to the wiring device 1a.

[0053] Next, in the display structure 5 and the wiring device 1b according to the present embodiment, the contact body 161 may have a rotating member 70 and a display member 61a. The elastic member 50a may be a leaf spring.

[0054] In this case, the display structure 5 and the wiring device 1b will be described with reference to Fig. 5 and Fig. 6. Fig. 5 is an exploded perspective view showing the wiring device 1b in which the display member 61a is exposed from the opening 122 by the rotating member 70. Fig. 6 is a cross-sectional view showing the wiring device 1b in which the display member 61a is exposed from the opening 122 by the rotating member 70. Fig. 6(a) shows the electric wire 90 before it is inserted into the insertion hole 112, and Fig. 6(b) shows the electric wire 90 inserted into the insertion hole 112 and electrically connected to the terminal 20.

[0055] The same configurations and functions as those of the display structure 5 and wiring device 1b described above are denoted by the same reference numerals as above, and the description thereof will be omitted as appropriate.

[0056] 5, the rotating member 70 is rotatably supported inside the housing 10. Specifically, the rotating member 70 is disposed in a guide groove portion 121 of the second housing 120, and is rotatably supported in the guide groove portion 121 with the Y-axis direction as its axis.

[0057] The rotary member 70 has a rotary body 71 and a pair of shaft portions 72 .

[0058] The rotating body 71 is disposed in the guide groove portion 121 and has a long columnar shape extending along the X-axis direction.

[0059] The pair of shaft portions 72 protrude in the Y-axis direction from the rotating body 71. Specifically, one of the pair of shaft portions 72 protrudes in the positive direction of the Y-axis from the rotating body 71. The other of the pair of shaft portions 72 protrudes in the negative direction of the Y-axis from the rotating body 71.

[0060] A pair of shaft support portions 125 for supporting the pair of shaft portions 72 are formed in the guide groove portion 121. The pair of shaft support portions 125 are recesses that correspond one-to-one to the pair of shaft portions 72. The pair of shaft support portions 125 support the pair of shaft portions 72 that slide when the rotating member 70 rotates.

[0061] The rotating body 71 has a protrusion 73 that comes into contact with the elastic member 50a and elastically deforms it. That is, when the rotating member 70 rotates, the protrusion 73 presses against the elastic member 50a and elastically deforms the elastic member 50a. The protrusion 73 is formed at the end of the rotating body 71 on the positive side of the X-axis.

[0062] The display member 61a has a rectangular parallelepiped shape. The display member 61a is arranged to be movable in the X-axis direction in the guide groove portion 121. An indicator pattern 63 is provided on the surface of the display member 61a on the negative Z-axis side.

[0063] The display member 61a is formed with a connecting portion 65 for connecting and fixing to the elastic member 50a. The connecting portion 65 is, for example, a pin that protrudes in the positive direction of the Z axis.

[0064] The elastic member 50a is a flat spring having a first fixing portion 51a, a second fixing portion 52a, and a pressing spring portion 53a.

[0065] The first fixed portion 51a is fixed to the second housing 120 by being connected to a connecting portion 126 formed on the second housing 120. The connecting portion 126 is, for example, a pin that protrudes in the positive direction of the Z axis.

[0066] The second fixing portion 52a is connected to and fixed to the connecting portion 65 of the display member 61a.

[0067] The pressing spring portion 53a is located between the first fixed portion 51a and the second fixed portion 52a and is bent in a V-shape. The first fixed portion 51a is connected to the end of the pressing spring portion 53a on the negative side of the X-axis, and the second fixed portion 52a is connected to the end of the pressing spring portion 53a on the positive side of the X-axis. When the rotating member 70 rotates, the pressing spring portion 53a is pressed by the convex portion 73 of the rotating member 70 and is thereby elastically deformed. When the pressing spring portion 53a elastically deforms, it can move the second fixed portion 52a in the positive direction of the X-axis within the guide groove portion 121.

[0068] In the display structure 5 and the wiring device 1b in Figures 5 and 6(a) and (b), the rotating member 70 is pressed by the electric wire 90 inserted into the insertion hole 112, causing it to rotate about the axis of the pair of shaft portions 72 extending in the Y-axis direction and press the elastic member 50a in the rotational direction, thereby elastically deforming the elastic member 50a. In other words, when the rotating member 70 is pressed by the electric wire 90 and rotates, the convex portion 73 of the rotating member 70 presses the pressing spring portion 53a of the elastic member 50a, elastically deforming the pressing spring portion 53a. The pressing spring portion 53a is pressed in the negative Z-axis direction by the convex portion 73 of the rotating member 70 and elastically deforms, so that the second fixing portion 52a moves in the positive X-axis direction inside the guide groove portion 121.

[0069] As a result, the indicator member 61a fixed to the second fixing portion 52a also moves in the positive direction of the X-axis. At this time, the indicator member 61a moves in accordance with the elastic deformation of the elastic member 50a so that the opening area of ​​the opening 122 becomes smaller. The indicator pattern 63, which is a part of the indicator member 61a, is exposed from the opening 122. This indicates that the electric wire 90 is electrically connected to the terminal 20, allowing the worker to recognize that the electric wire 90 is electrically connected to the terminal 20.

[0070] Next, in the display structure 5 and the wiring device 1c according to the present embodiment, the contact body 162 may have a rotating member 70a.

[0071] In this case, the display structure 5 and the wiring device 1c will be described with reference to Fig. 7. Fig. 7 is a cross-sectional view showing another wiring device 1c in which a rotating member 70a exposes a display member from an opening 122. Fig. 7(a) shows the state before the electric wire 90 is inserted into the insertion hole 112, and Fig. 7(b) shows the state after the electric wire 90 has been inserted into the insertion hole 112 and the electric wire 90 and the terminal 20 are electrically connected.

[0072] The same components and functions as those of the display structure 5 and wiring device 1c described above are denoted by the same reference numerals as above, and the description thereof will be omitted as appropriate.

[0073] The contact body 162 has a rotary member 70 a with which the tip of the electric wire 90 inserted into the insertion hole 112 comes into contact.

[0074] The rotating member 70a is rotatably supported inside the housing 10. Specifically, the rotating member 70a is disposed in a guide groove portion 121 of the second housing 120, and is rotatably supported in the guide groove portion 121 with the Y-axis direction as its axis.

[0075] The rotary member 70 a has a rotary body 71 and a pair of shaft portions 72 .

[0076] The rotating body 71 is disposed in the guide groove portion 121 and has a long columnar shape extending along the X-axis direction.

[0077] The pair of shaft portions 72 protrude in the Y-axis direction from the rotating body 71. Specifically, one of the pair of shaft portions 72 protrudes from the surface of the rotating body 71 on the positive side of the Y-axis. The other of the pair of shaft portions 72 protrudes from the surface of the rotating body 71 on the negative side of the Y-axis.

[0078] A pair of shaft support portions 125 for supporting the pair of shaft portions 72 are formed in the guide groove portion 121. The pair of shaft support portions 125 are recesses that correspond one-to-one to the pair of shaft portions 72. The pair of shaft support portions 125 support the pair of shaft portions 72 that slide when the rotating member 70a rotates.

[0079] 7(a) and 7(b), the rotation member 70a is a display member. An indicator pattern 63 is provided on the surface of the rotation member 70a on the positive side of the X axis.

[0080] The rotating member 70a is pressed by the electric wire 90 inserted into the insertion hole 112, thereby elastically deforming the elastic member 50 and protruding from the opening 122. In other words, the rotating member 70a is pressed by the electric wire 90 inserted into the insertion hole 112, thereby rotating about the axis of the pair of shaft portions 72 extending in the Y-axis direction and pressing against the elastic member 50, thereby elastically deforming the elastic member 50. At this time, the rotating member 70a moves so that the opening area of ​​the opening 122 becomes smaller in accordance with the elastic deformation of the elastic member 50, and a portion of the rotating member 70a protrudes from the opening 122. A portion of the rotating member 70a protrudes in a direction substantially opposite to the insertion direction of the electric wire 90 inserted into the insertion hole 112.

[0081] The elastic member 50 may be provided on, for example, the pair of shaft portions 72. The elastic member 50 may also be provided between the rotating member 70a and the second housing 120.

[0082] Since the indicator pattern 63 is provided on the end face of the rotating member 70a on the positive side of the X-axis, when a part of the rotating member 70a protrudes from the opening 122, the indicator pattern 63 can be seen from the positive side of the X-axis. This indicates that the electric wire 90 is electrically connected to the terminal 20, and the worker can recognize that the electric wire 90 is electrically connected to the terminal 20.

[0083] Next, in the display structure 5 and the wiring device 1d according to the present embodiment, the contact body 163 may have a rotating member 70c and a display member 63a. Also, the elastic member 50 may be a coil spring.

[0084] In this case, the display structure 5 and the wiring device 1d will be described with reference to Fig. 8. Fig. 8 is a cross-sectional view showing the wiring device 1d having a rotating member 70c, a display member 63a, and a coil spring elastic member 50. Fig. 8(a) shows the state before the electric wire 90 is inserted into the insertion hole 112, and Fig. 8(b) shows the state after the electric wire 90 has been inserted into the insertion hole 112 and the electric wire 90 and the terminal 20 are electrically connected.

[0085] The same components and functions as those of the display structure 5 and wiring device 1d described above are denoted by the same reference numerals as above, and the description thereof will be omitted as appropriate.

[0086] The rotating member 70c is rotatably supported inside the housing 10. Specifically, the rotating member 70c is disposed in a guide groove portion 121 of the second housing 120, and is rotatably supported in the guide groove portion 121 with the Y-axis direction as its axis.

[0087] The rotary member 70 c has a rotary body 71 and a pair of shaft portions 72 .

[0088] The rotating body 71 is disposed in the guide groove portion 121 and has a long columnar shape extending along the X-axis direction.

[0089] The pair of shaft portions 72 protrude in the Y-axis direction from the rotating body 71. Specifically, one of the pair of shaft portions 72 protrudes from the surface of the rotating body 71 on the positive side of the Y-axis. The other of the pair of shaft portions 72 protrudes from the surface of the rotating body 71 on the negative side of the Y-axis.

[0090] A pair of shaft support portions 125 for supporting the pair of shaft portions 72 are formed in the guide groove portion 121. The pair of shaft support portions 125 are recesses that correspond one-to-one to the pair of shaft portions 72. The pair of shaft support portions 125 support the pair of shaft portions 72 that slide when the rotating member 70c rotates.

[0091] The display member 63a has a columnar shape that is long in the X-axis direction. The display member 63a is arranged in the guide groove portion 121 so as to be movable in the X-axis direction. A first inclined surface 261 is formed at the end of the display member 63a on the negative X-axis side. When the wiring fixture 1d is viewed in cross section as shown in FIG. 8, the first inclined surface 261 is inclined downward toward the negative X-axis direction. The first inclined surface 261 is arranged to face the protrusion 73 of the rotating main body 71.

[0092] The protrusion 73 is formed at the end of the rotating body 71 on the positive side of the X-axis. The protrusion 73 comes into contact with the display member 63a and can move the display member 63a.

[0093] In the display structure 5 and wiring device 1d shown in FIGS. 8(a) and 8(b), the rotating member 70c is pressed by the electric wire 90 inserted into the insertion hole 112, causing it to rotate around the axis of the pair of shafts 72 extending in the Y-axis direction. The rotating member 70c comes into contact with the first inclined surface 261 of the display member 63a and presses the first inclined surface 261 in the negative direction of the Z-axis. At this time, the convex portion 73 slides along the first inclined surface 261, causing the display member 63a to move in the positive direction of the X-axis while being guided by the guide groove portion 121, elastically deforming the elastic member 50. In other words, the rotating member 70c is pressed by the electric wire 90 inserted into the insertion hole 112, causing the display member 63a to elastically deform. The display member 63a moves in such a way that the opening area of ​​the opening 122 decreases in response to the elastic deformation of the elastic member 50. The display pattern 63, which is a part of the display member 63a, is exposed through the opening 122. This indicates that the electric wire 90 is electrically connected to the terminal 20, and the worker can recognize that the electric wire 90 is electrically connected to the terminal 20.

[0094] Next, in the display structure 5 and the wiring fixture 1e according to the present embodiment, the contact body 164 may have a rotating member 70d and a display member 64a. The elastic member 50 may be a coil spring.

[0095] In this case, the display structure 5 and the wiring device 1e will be described with reference to Fig. 9. Fig. 9 is a cross-sectional view showing the wiring device 1e in which the display member 64a protrudes from the opening 122. Fig. 9(a) shows the state before the electric wire 90 is inserted into the insertion hole 112, and Fig. 9(b) shows the state after the electric wire 90 has been inserted into the insertion hole 112 and the electric wire 90 and the terminal 20 are electrically connected.

[0096] The same components and functions as those of the display structure 5 and wiring device 1e described above are denoted by the same reference numerals as above, and the description thereof will be omitted as appropriate.

[0097] The rotating member 70d is rotatably supported inside the housing 10. Specifically, the rotating member 70d is disposed in a guide groove portion 121 of the second housing 120, and is rotatably supported in the guide groove portion 121 with the Y-axis direction as its axis.

[0098] The rotary member 70d has a rotary body 71 and a pair of shaft portions 72.

[0099] The rotating body 71 is disposed in the guide groove portion 121 and has a long columnar shape extending along the X-axis direction.

[0100] The pair of shaft portions 72 protrude in the Y-axis direction from the rotating body 71. Specifically, one of the pair of shaft portions 72 protrudes from the surface of the rotating body 71 on the positive side of the Y-axis. The other of the pair of shaft portions 72 protrudes from the surface of the rotating body 71 on the negative side of the Y-axis.

[0101] A pair of shaft support portions 125 for supporting the pair of shaft portions 72 are formed in the guide groove portion 121. The pair of shaft support portions 125 are recesses that correspond one-to-one to the pair of shaft portions 72. The pair of shaft support portions 125 support the pair of shaft portions 72 that slide when the rotating member 70d rotates.

[0102] The elastic member 50 is disposed between the second housing 120 and the display member 64a so as to elastically deform the display member 64a when pressed in the negative Z-axis direction. In other words, the elastic member 50 elastically deforms along the Z-axis direction, and can therefore urge the display member 64a in the positive Z-axis direction.

[0103] The display member 64a has a columnar shape that is long in the X-axis direction. The display member 64a is arranged so as to be movable in the Z-axis direction in the guide groove portion 121. The display member 64a is arranged so as to face the protrusion 73 of the rotating body 71.

[0104] The protrusion 73 is formed at the end of the rotating body 71 on the positive side of the X axis. The protrusion 73 can come into contact with the display member 64a to move the display member 64a.

[0105] Specifically, when pressed by the electric wire 90 inserted into the insertion hole 112, the rotation member 70d rotates about the axis of the pair of shaft portions 72 extending in the Y-axis direction, comes into contact with the display member 64a, and can press the display member 64a in the negative Z-axis direction. At this time, the display member 64a moves in the negative Z-axis direction while being guided by the guide groove portion 121, while elastically deforming the elastic member 50. In other words, when pressed by the electric wire 90 inserted into the insertion hole 112, the rotation member 70d presses the display member 64a, elastically deforming the elastic member 50, and moves the display member 64a so that the opening area of ​​the opening 122 decreases in accordance with the elastic deformation of the elastic member 50. The rotation member 70d then causes the display member 64a to protrude from the opening 122. In other words, the display member 64a moves in a direction substantially opposite to the insertion direction of the electric wire 90 inserted into the insertion hole 112.

[0106] 9(a) and 9(b), the display structure 5 and the wiring device 1e have the display pattern 63 provided on the end face of the rotating member 70d on the positive side of the X-axis, and therefore, when a part of the rotating member 70d protrudes from the opening 122, the display pattern 63 can be seen from the positive side of the X-axis. This indicates that the electric wire 90 is electrically connected to the terminal 20, and the worker can recognize that the electric wire 90 is electrically connected to the terminal 20.

[0107] <Action and effect> Next, the effects of the display structure 5 and the wiring devices 1, 1a, 1b, 1c, 1d, and 1e according to the present embodiment will be described.

[0108] As described above, the display structure 5 of technology 1 in this embodiment is a display structure 5 arranged inside the housing 10 for electrically connecting the electric wire 90 inserted through the insertion hole 112 formed in the housing 10 to the terminal 20 arranged inside the housing 10, and is provided with contact bodies 60, 160, 161, 162, 163, 164 with which the tip of the inserted electric wire 90 comes into contact, and elastic members 50, 50a, and the housing 10 has an opening 122 that opens in the same direction as the opening of the insertion hole 112. The contact bodies 60, 160, 161, 162, 163, 164 are pressed by the electric wire 90 inserted into the insertion hole 112, causing the elastic members 50, 50a to elastically deform, and the opening area of ​​the opening 122 moves to become smaller in accordance with the elastic deformation of the elastic members 50, 50a.

[0109] With this, when the electric wire 90 is inserted into the insertion hole 112, the contact bodies 60, 160, 161, 162, 163, and 164 are exposed from the opening 122. This allows the worker to recognize that the electric wire 90 and the terminal 20 are electrically connected.

[0110] Furthermore, the contact bodies 60, 160, 161, 162, 163, 164 can be biased so as not to be unexpectedly exposed from the opening 122. For example, when the electric wire 90 is separated from the contact bodies 60, 160, 161, 162, 163, 164, the elastic members 50, 50a move the contact bodies 60, 160, 161, 162, 163, 164, so that the contact bodies 60, 160, 161, 162, 163, 164 are not exposed from the opening 122. This allows the worker to recognize that the electric wire 90 and the terminal 20 are not electrically connected.

[0111] Therefore, the indicator structure 5 can indicate that the electric wire 90 is electrically connected to the terminal 20.

[0112] In addition, in the display structure 5 of technology 2 in this embodiment, the contact body 60, 160 has a display member 60a, and the display member 60a elastically deforms the elastic member 50 when pressed by the electric wire 90 inserted into the insertion hole 112, and moves so that the opening area of ​​the opening 122 becomes smaller in accordance with the elastic deformation of the elastic member 50.

[0113] According to this, the indicator 60 a is exposed from the opening 122 , and therefore the indicator 60 a can indicate that the electric wire 90 is electrically connected to the terminal 20 .

[0114] Furthermore, in the display structure 5 of technology 3 in this embodiment, the contact bodies 60, 160 have a display member 60a and a wire receiving member 60b, and the wire receiving member 60b is arranged inside the housing 10, and when pressed by the wire 90 inserted into the insertion hole 112, it elastically deforms the elastic member 50 via the display member 60a, and the display member 60a moves in accordance with the elastic deformation of the elastic member 50 so that the opening area of ​​the opening 122 becomes smaller.

[0115] If the electric wire directly moves the indicator member, the tip of the electric wire may get caught on the indicator member, making it difficult to move the indicator member. However, according to this embodiment, the electric wire receiving member 60b transmits the pressing force from the electric wire 90 to the indicator member 60a, and the pressing force moves the indicator member 60a, allowing the indicator member 60a to be exposed from the opening 122. Therefore, the indicator member 60a can indicate that the electric wire 90 is electrically connected to the terminal 20.

[0116] In addition, in the display structure 5 of technology 4 in this embodiment, a first inclined surface 61 is formed on the display member 60a, and the display member 60a moves when the first inclined surface 61 is pressed by the electric wire 90 inserted into the insertion hole 112.

[0117] According to this, when the electric wire 90 presses against the first inclined surface 61, the tip of the electric wire 90 can slide along the first inclined surface 61, thereby preventing the tip of the electric wire 90 from getting caught on the display member 60a. Since the pressing force from the electric wire 90 exposes the display member 60a from the opening 122, the display member 60a can indicate that the electric wire 90 is electrically connected to the terminal 20.

[0118] Furthermore, in the display structure 5 of technology 5 in this embodiment, a first inclined surface 61 is formed on the display member 60a, and a second inclined surface 62 is formed on the electric wire receiving member 60b, which contacts the first inclined surface 61 of the display member 60a and is pressed by the first inclined surface 61, and as the electric wire receiving member 60b moves along the insertion direction of the electric wire 90 inserted into the insertion hole 112, the second inclined surface 62 of the electric wire receiving member 60b presses the first inclined surface 61 of the display member 60a, and the display member 60a moves.

[0119] If the electric wire directly moves the display member, it is conceivable that the tip of the electric wire may get caught on the display member, making it difficult to move the display member. However, according to this embodiment, the second inclined surface 62 of the electric wire receiving member 60b transmits the pressing force from the electric wire 90 to the first inclined surface 61 of the display member 60a, and the pressing force makes it possible to easily move the display member 60a.

[0120] In the display structure 5 of the sixth aspect of the present embodiment, the elastic member 50 is a coil spring, and is disposed between the housing 10 and the display member 60a.

[0121] This allows the use of commonly available materials, making it possible to easily manufacture the display structure 5.

[0122] In the display structure 5 of the seventh technique according to the present embodiment, the display member 60a moves in a direction substantially perpendicular to the insertion direction of the electric wire 90 inserted into the insertion hole 112.

[0123] This allows the indicator 60a to indicate that the electric wire 90 has been connected to the terminal 20 in a direction different from the insertion direction. The indicator 60a can be exposed from the opening 122 that opens in the same direction as the opening of the insertion hole 112. This allows the worker to recognize that the electric wire 90 and the terminal 20 have been electrically connected while inserting the electric wire 90 while looking at the insertion hole 112.

[0124] Furthermore, in the display structure 5 of technology 8 in this embodiment, the contact bodies 161, 162, 163, 164 have rotating members 70, 70a, 70c, 70d that come into contact with the tip of the electric wire 90 inserted into the insertion hole 112, and the rotating members 70, 70a, 70c, 70d are rotatably supported inside the housing 10. When pressed by the electric wire 90 inserted into the insertion hole 112, the rotating members 70, 70a, 70c, 70d are pressed in the rotational direction by the elastic members 50, 50a, thereby elastically deforming the elastic members 50, 50a, and the rotating members 70, 70a, 70c, 70d move in accordance with the elastic deformation of the elastic members 50, 50a so that the opening area of ​​the opening 122 becomes smaller.

[0125] This allows the rotating members 70, 70a, 70c, and 70d to rotate easily even if the pressing force from the electric wire 90 is small or the tip of the electric wire 90 is soft. Therefore, the rotating members 70, 70a, 70c, and 70d can move so as to reduce the opening area of ​​the opening 122. This allows the worker to insert the electric wire 90 while looking at the insertion hole 112 and simultaneously recognize that the electric wire 90 and the terminal 20 are electrically connected, regardless of the type of electric wire 90.

[0126] In the case of the rotary member 70a, since the rotary member 70a is exposed from the opening 122, the rotary member 70a can indicate that the electric wire 90 is electrically connected to the terminal 20.

[0127] Furthermore, in the display structure 5 of technology 9 in this embodiment, the contact body 161 further has a display member 61a, and the rotating member 70 is pressed by the electric wire 90 inserted into the insertion hole 112, thereby elastically deforming the elastic member 50a, and the display member 61a moves in accordance with the elastic deformation of the elastic member 50a so that the opening area of ​​the opening 122 becomes smaller.

[0128] According to this, the display member 61a is exposed from the opening 122 when the rotary member 70 rotates, so that the display member 61a can indicate that the electric wire 90 is electrically connected to the terminal 20.

[0129] Furthermore, in the display structure 5 of technology 10 in this embodiment, the elastic member 50a is a leaf spring having a first fixing portion 51a and a second fixing portion 52a, and the first fixing portion 51a is fixed to the housing 10, and the second fixing portion 52a is fixed to the display member 61a.

[0130] This allows the use of commonly available materials, making it possible to easily manufacture the display structure 5.

[0131] Furthermore, when the elastic member 50a is elastically deformed, the display member 61a can be moved relative to the housing 10, and the display member 61a can be exposed from the opening 122.

[0132] In the display structure 5 of technique 11 according to the present embodiment, the rotation member 70 has a protrusion 73 that contacts the elastic member 50a and causes it to elastically deform.

[0133] This allows the elastic member 50a, which is a leaf spring, to be elastically deformed appropriately.

[0134] In addition, in the display structure 5 of technology 12 in this embodiment, the rotating member 70a is a display member, and the rotating member 70a elastically deforms the elastic member 50 when pressed by the electric wire 90 inserted into the insertion hole 112, and protrudes from the opening 122.

[0135] This allows the worker to recognize the rotating member 70a protruding from the opening 122 while the rotating member 70a is exposed from the opening 122. Therefore, for example, when the worker inserts the wire 90 into the insertion hole 112 while looking in a direction intersecting the insertion direction (the side surface of the housing 10), the worker can recognize the rotating member 70a protruding from the opening 122.

[0136] Furthermore, in the display structure 5 of technology 13 in this embodiment, the contact body 163 further has a display member 63a, and the rotating member 70c is pressed by the electric wire 90 inserted into the insertion hole 112, thereby pressing the display member 63a and elastically deforming the elastic member 50, and the display member 63a moves in accordance with the elastic deformation of the elastic member 50 so that the opening area of ​​the opening 122 becomes smaller.

[0137] According to this, the rotating member 70c exposes the indicator member 63a from the opening 122, so that the indicator member 63a can indicate that the electric wire 90 is electrically connected to the terminal 20.

[0138] Furthermore, in the display structure 5 of technology 14 in this embodiment, the contact body 164 further has a display member 64a, and the rotating member 70d is pressed by the electric wire 90 inserted into the insertion hole 112, thereby pressing the display member 64a and elastically deforming the elastic member 50, causing the display member 64a to protrude from the opening 122.

[0139] This allows the worker to recognize the indicator member 64a protruding from the opening 122 while the indicator member 64a is exposed from the opening 122. Therefore, for example, when the worker inserts the wire 90 into the insertion hole 112 while looking in a direction intersecting the insertion direction (the side surface of the housing 10), the worker can recognize the indicator member 64a protruding from the opening 122.

[0140] In the display structure 5 of technique 15 according to the present embodiment, the elastic member 50 is a coil spring, and is disposed between the housing 10 and the display members 63a and 64a.

[0141] This allows the use of commonly available materials, making it possible to easily manufacture the display structure 5.

[0142] Furthermore, in the display structure 5 of technology 16 in this embodiment, a first inclined surface 61 is formed on the display member 63a, and the rotating member 70c has a convex portion 73 that contacts the first inclined surface 61 and presses the display member 63a, and the convex portion 73 elastically deforms the elastic member 50, which is a coil spring, by pressing the display member 63a, and the display member 63a moves in accordance with the elastic deformation of the elastic member 50 so that the opening area of ​​the opening 122 becomes smaller.

[0143] This allows the elastic member 50, which is a coil spring, to be elastically deformed appropriately.

[0144] In the display structure 5 of technique 17 according to the present embodiment, a part of the rotation member 70a protrudes in a direction substantially opposite to the insertion direction of the electric wire 90 inserted into the insertion hole 112.

[0145] This allows the worker to see the insertion hole 112 while inserting the electric wire 90 and at the same time recognize that the electric wire 90 and the terminal 20 are electrically connected.

[0146] Furthermore, the wiring devices 1, 1a, 1b, 1c, 1d, and 1e of the present embodiment according to Technology 18 include the above-described display structure 5 disposed inside the housing of the outlet or the housing of the switch, and a housing 10.

[0147] In this case, the same effects as those described above are achieved.
