Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device plate fixed to a construction surface so as to cover a mounting hole formed in the construction surface for mounting a wiring device.

[0002]

2. Description of the Related Art Generally, to mount an embedded wiring device on a construction surface such as a wall surface, a part of the wiring device is fixed by embedding a part of the wiring device in a mounting hole formed on the construction surface. The wiring device plate is fixed to the construction surface so as to cover the mounting hole, leaving the.

As a wiring device plate, as shown in FIG. 19, a frame-shaped plate body 1 fixed to a construction surface.
b) and a decorative plate 2 that has a window hole 21 that exposes a part of the wiring device and that is joined to the plate body 1b in a form of covering the plate body 1b are widely used. As the decorative plate 2, a blank plate having no window hole is also prepared in case that the wiring device is removed from the mounting hole or a spare mounting hole is formed.

The plate body 1b is a plate body 1b.
Is generally fixed to the construction surface with screws, and a decorative plate 2 that covers the front surface of the plate body 1b is used in order to conceal the screw heads and finish the appearance. The decorative plate 2 includes an assembly leg 25 protruding rearward so as to be coupled to the plate body 1b without using screws,
A hook claw 25a is provided at the rear end of the assembly leg 25. That is, in order to connect the decorative plate 2 to the plate body 1b, the assembly leg 25 is inserted into the assembly hole 15 provided in the peripheral portion of the plate body 1b, and the peripheral portion of the decorative plate 2 contacts the construction surface. At the position, the dimensions of the assembly leg 25 and the assembly hole 15 are set so that the hooking claw 25a provided at the rear end of the assembly leg 25 is locked to the rear end peripheral edge of the assembly hole 15. In short, after fixing the wiring device to the construction surface, the plate body 1b is fixed to the construction surface, and then the decorative plate 2 is coupled to the plate body 1b.

As the decorative plate 2, one having a rectangular frame shape and a rectangular window hole 21 in the central portion is widely used. In the decorative plate 2 of this shape, in order to prevent the peripheral portion from being lifted up due to the warp of the decorative plate 2 in the state of being mounted on the plate body 1b, the assembly leg 25
Are provided at the four corners of the decorative plate 2, so that the distance between the assembly legs 25 in the longitudinal direction and the width direction of the decorative plate 2 is as large as possible. In other words, the assembly leg 25 is provided so as to project outside the widthwise peripheral edge of the window hole 21, and the hooks 25a are provided so as to project toward each other in the widthwise direction of the window hole 21.

[0006]

By the way, the plate body 1b and the decorative plate 2 are synthetic resin molded products, and the plate body 1b and the decorative plate 2 are often made of the same material. Since it is considered that there is no substantial difference in the contraction rate between the plate body 1b and the decorative plate 2 during the operation, the plate body 1b
Even if the decorative plate 2 contracts, the engagement allowance of the hook 25a with respect to the assembly hole 15 does not substantially change, and the decorative plate 2 is held against the plate body 1b with the designed strength.

However, when the plate body 1b is formed continuously and integrally with the body of the wiring device, the material forming the plate body 1b is required to have insulation properties and tracking resistance, and thus the formability and the resistance to tracking are required. It is conceivable to use a material different from the decorative plate that is required to have impact resistance. In such a case, the contraction rate of the plate body 1b may be larger than that of the decorative plate 2. The cause of the shrinkage is not only the shrinkage of the molded product size with respect to the mold size but also the shrinkage due to temperature change and aging.

As described above, when the contraction rate of the plate body 1b is larger than that of the decorative plate 2,
When the plate body 1 contracts, the engagement allowance of the hooking claw 25a with respect to the assembly hole 15 decreases, so that the decorative plate 2
There is a problem that it becomes easy to come off. That is, even if a relatively small impact force acts on the decorative plate 2, the decorative plate 2 may fall off the plate body 1b. The contraction rates of the plate body 1b and the decorative plate 2 are relative to each other, and the same problem occurs when the expansion rate of the plate body 1b is smaller than that of the decorative plate 2.

The present invention has been made in view of the above circumstances, and an object thereof is to prepare a decorative plate even if the plate body is made of a material having a relatively large shrinkage ratio with respect to the decorative plate. It is to provide a wiring device plate that can be prevented from falling off.

Further, a ground spring 13 is exposed at two locations on the peripheral surface of the plug receiving recess 11a, and a plug (so-called C-type) having a contact that is inserted into the second insertion portion 12y and a ground electrode is exposed on the side surface is provided. When used, the grounding spring 13 makes elastic contact with the grounding electrode of the plug.

In the protrusion 1c, screw receiving recesses 11b are formed at both ends in the left-right direction in FIG. 4 and across the plate body 1b. The bottom surface of the screw receiving recess 11b is located in front of the bottom surface of the plug receiving recess 11a and behind the front surface of the plate body 1b. The screw receiving recess 11b is in contact with the plug receiving recess 11a, and the screw receiving recess 11b and the plug receiving recess 11a communicate with each other. Further, on the bottom surface of the screw receiving recess 11b, there is formed a screw hole 14 having a long hole in the up-down direction, which is substantially similar to the inner peripheral edge of the screw receiving recess 11b. Further, assembly holes 15 are formed above and below the screw receiving recess 11b in the plate body 1b.

Here, an inclined surface 16 (see FIGS. 1 and 8) is formed in the peripheral portion of the plate body 1b so as to be inclined toward the outer peripheral side so that the distance from the rear surface of the plate body 1b becomes smaller toward the outer peripheral side. It is formed. A rising surface 17 along the front-rear direction is formed on the outer periphery of the plate body 1b, and the front end edge of the rising surface 17 intersects the outer peripheral edge of the inclined surface 16. The contour of the rising surface 17 is a shape in which the corners of a rectangle are chamfered, and projecting pieces 18 are projectingly provided on the rear portion of the rising surface 17 at the portions corresponding to the four straight line portions.
That is, the rising surface 17 and the tip end surface of the protruding piece 18 become the peripheral surface of the plate body 1b. The front end surface of the protruding piece 18 is a surface along the front-rear direction, and a plurality of press-fitting ribs 19 are provided on the front end surface of each protruding piece 18, respectively. Each press-fitting rib 19
Is extended in the front-back direction. Of the four protrusions 18,
At the left and right ends of the lower projecting piece 18 in FIG. 4, a detaching stand 18b is provided to project downward. The function of the removing table 18b will be described later.

On the other hand, the decorative plate 2 is shown in FIGS.
As shown in FIG. 2, it is formed in a rectangular frame shape having a window hole 21 that opens in a rectangular shape along the outer peripheral edge of the protrusion 1c provided on the cover plate 1. That is, the decorative plate 2 is the front wall 2
A window hole 21 is opened at the center of the front wall 22, and a peripheral wall 23 is formed in a shape extending rearward over the entire circumference of the outer peripheral edge of the front wall 22. A cover piece 21a is provided on the inner peripheral edge of the window hole 21 so as to cover a part of the screw receiving recess 11b. That is,
The plug receiving recess 11a and the screw receiving recess 11b provided in the cover plate 1 are continuous, and the screw receiving recess 11b is provided.
Since a part of the cover is formed by notching a part of the protrusion 1c, the cover piece 21a is formed so as to be inserted into the notch of the protrusion 1c. The inner side surface of the peripheral wall 23 has a rectangular shape along the contour of the plate body 1b, and is formed along the front-rear direction so as to be capable of contacting the tip end surface of the projecting piece 18. Positioning ribs 24 that can come into contact with the front surface of each of the projecting pieces 2 are provided on the inner surface of the decorative plate 2 where the front wall 22 and the peripheral wall 23 are continuous. Further, in the decorative plate 2, the lower peripheral wall 23 of FIG. 10 is cut out with a removal groove 23a into which the removal table 18b of the cover plate 1 is inserted.

By the way, as shown in FIG. 10, four assembly legs 25, which are respectively inserted into the assembly holes 15 provided in the cover plate 1, are projectingly provided around the window hole 21 in the decorative plate 2. . As shown in FIG. 1, a hooking claw 25a that can be locked to the rear end peripheral edge of the assembly hole 15 is provided at the rear end (front end) of each assembly leg 25. The intermediate portion of the assembly leg 25 and the surface on which the hooking claw 25a is provided are formed in a flat shape. The peripheral wall 23 of the decorative plate 2 is the plate body 1
Position where the protrusion 18 of b is overlapped (that is, the rear surface of the plate body 1b and the rear surface of the decorative plate 2 are flush with each other, and the tip surface of the protrusion 18 and the inner surface of the peripheral wall 23 are overlapped)
Then, the hooking claw 25a is not locked to the peripheral edge of the assembly hole 15,
Decorative plate 2 is plate body 1 with respect to the above position
so that the hooking claw 25a is locked in the assembly hole 15 at a position spaced apart from the front by a predetermined distance.
The dimensional relationship with is set. This predetermined distance is set to about the thickness dimension of a general cloth attached to the construction surface. Therefore, when the cloth is sandwiched between the plate body 1b and the decorative plate 2, the hooking claw 25a is locked to the peripheral edge of the locking hole 15 and the decorative plate 2 is fixed to the cover plate 1 without rattling. To be done. At this time, the thickness dimension of the projecting piece 18 in the front-rear direction is set so that the inner surface of the peripheral wall 23 of the decorative cover 5 does not overlap the tip surface of the projecting piece 18. Further, in this state, a gap is formed between the inclined surface 16 provided on the plate body 1b and the front wall 22 of the decorative plate 2 such that a cloth can be inserted between the plate body 1b and the decorative plate 2. The dimensional relationship is set. Here, since the press-fitting rib 19 contacts the back surface of the cloth, the press-fitting rib 19 also functions as a slip stopper for the cloth.

When the thickness of the cloth is relatively small, the decorative plate 2 may not be fixed at the position where the hook 25a is locked in the locking hole 15, but the hook 25a may be fixed.
Since the decorative plate 2 is provided, the decorative plate 2 is prevented from falling off the cover plate 1. Further, the press-fitting rib 1 is provided on the tip surface of the protrusion 18 provided on the cover plate 1.
9 is projected, and when the cloth is not sandwiched between the cover plate 1 and the decorative plate 2, the decorative plate 2
Is deeply fitted into the cover plate 1 and the press-fitting rib 19 is pressed against the inner surface of the peripheral wall 23 of the decorative plate 2, so that the decorative plate 2 is held on the cover plate 1 by the frictional force between the press-fitting rib 19 and the decorative plate 2. To be done.

The above-mentioned assembly legs 25 are provided at both ends in the longitudinal direction (horizontal direction) of the decorative plate 2, and each pair of assembly holes 2 adjacent in the width direction (vertical direction) of the window hole 21.
The interval of 5 is set smaller than the width dimension of the window hole 21. That is, the gap is narrower in the vertical direction than the position of the assembly leg 25 in the conventional configuration shown by the chain double-dashed line in FIG. Since the space between the assembly legs 25 is thus narrowed, the space between the assembly holes 15 is also narrowed. Therefore, even if the cover plate 1 contracts, the dimensional change of the assembly holes 15 can be made relatively small. It is possible to prevent a large stress from being generated in the assembly leg 25. However, if the vertical distance between the assembly legs 25 is too narrow, the upper and lower ends of the decorative plate 2 are likely to rise from the cover plate 1 when the decorative plate 2 is attached to the cover plate 1, so that the vertical direction of the assembly legs 25 is reduced. The interval is made to substantially match the width dimension of the window hole 21.

The above-mentioned hooking claws 25a of the assembly legs 25 arranged in the vertical direction project in a direction away from the other assembly leg 25. That is, the hook claw 25a projects from one surface of the assembly leg 25 on the outer peripheral side of the decorative plate 2. In the conventional configuration, as shown in FIG. 1C, the hooking claws 25a protrude from the upper and lower assembly legs 25 so as to approach each other, whereas in the present embodiment, the hooking claws 25a are mutually connected as shown in FIG. 1B. Projects away. In short, in this embodiment, the hook 25a of the upper assembly leg 25 projects upward, and the hook 25a of the lower assembly leg 25 projects downward. In this embodiment, the cover plate 1 is made of a material having a shrinkage rate higher than that of the decorative plate 2, and at the time of shrinkage, the two assembly holes 1 are more than the distance between the two assembly legs 25.
Although the distance between 5 is smaller, since the hooks 25a project in the above-described direction, the hooks 25a are retracted into the engagement holes 15 when the cover plate 1 and the decorative plate 2 are contracted. As a result, the decorative plate 2 is prevented from coming off from the cover plate 1 by a slight impact even when contracting.

Further, as described above, the assembly legs 2 lined up and down.
The interval of 5 is smaller than the width dimension of the window hole 21, and the assembly leg 25 is arranged inside the extension lines of both side edges of the window hole 21 in the width direction. With this configuration, the gap between the peripheral wall 23 of the decorative plate 2 and the assembly leg 25 can be made relatively large, and the slides used when forming the hooking claws 25a projecting in the directions separated from each other in the vertically arranged assembly legs 25. The core can be easily inserted between the peripheral wall 23 and the assembly leg 25. That is, the structure of the mold including the slide core becomes relatively simple.

Further, as shown in FIG. 3 (a), the portion of the inner surface of the assembly hole 15 corresponding to the corner between the assembly leg 25 and the hook 25a is assembled into the assembly hole 15. Leg 2
Buffer part 15a having an arc-shaped cross section including the insertion direction of No. 5
Are formed. The portion where the buffer portion 15a is formed protrudes inside the assembly hole 15, and the tip end surface of the protruding portion is formed into an arc shape in cross section.
a is inclined so as to narrow the opening width from the opening side of the assembly hole 15 in the insertion direction of the assembly leg 25 toward the inside. Therefore, as compared with the configuration shown in FIG. 3B in which the cross-sectional shape of the opening of the assembly hole 15 is a right angle, the cover plate 1 and the decorative plate 2 contract as described above and the assembly hole 15 is formed. Even if the engagement allowance of the hooking claw 25a with respect to the peripheral edge of the assembly leg 25 increases, it is possible to suppress the concentration of stress generated in the assembly leg 25 by the contact of the buffer portion 15a with the assembly leg 25.

To remove the decorative plate 2 from the cover plate 1, a tool such as the tip of a flat-blade screwdriver is inserted between the removal groove 23a and the removal table 18b, and the tip of the tool is brought into contact with the projecting piece 18. In this state, a force for removing the decorative plate 2 from the cover plate 1 may be applied. Here, a notch is formed at a portion of the projecting piece 18 where the tip of the tool comes into contact so that the tip of the tool is inserted to prevent the tool from slipping. When the tool is removed and inserted into the groove 23a in order to remove the decorative plate 2 from the cover plate 1, the vicinity of the part of the decorative plate 2 into which the tool is inserted floats up from the plate body 1b. Although the decorative plate 2 tends to sink due to the force acting toward the body 1b, the decorative plate 2 is provided with the positioning rib 24 that abuts on the front peripheral portion of the plate body 1b as described above. The positioning ribs 24 prevent the decorative plate 2 from sinking.
