As shown in FIGS. 1A and 1B, the wiring device mounting base 1 of the present embodiment is used for installing the wiring device 200 on the wall base 110. In the following description, for simplification of description, the left side in FIG. 1B is the front side of the wiring fixture mounting base 1, and the right side in FIG. 1B is the rear side of the wiring fixture mounting base 1. 1B is defined as the upper side of the wiring fixture mounting base 1, and the lower side of FIG. 1B is defined as the lower side of the wiring fixture mounting base 1, respectively.

  First, the wiring device 200 will be briefly described. This wiring device 200 is a so-called waterproof outlet, and includes a housing (device main body) 220 that houses an outlet main body 210 to which a plug is removably connected. The outlet body 210 is accommodated in the housing 220 in such a manner that the plug receptacle is exposed from the lower surface of the housing 220 (the lower surface in FIG. 1B). On the rear surface of the housing 220 (the right surface in FIG. 1B), an opening 221 for inserting an electric wire (not shown) into the housing 220 (an electric wire inserted through the electric wire insertion hole 111 of the wall base 110) is formed. . The electric wire inserted into the housing 220 from the opening 221 is connected to the outlet body 210. The housing 220 is formed with a pair of screw insertion holes 222 for fixing screws (not shown). The fixing screw is used to attach the wiring device 200 to the wiring device mounting base 1.

  By the way, a waterproof packing 230 is provided at the rear edge of the housing 220. The waterproof packing 230 includes a rear edge of the housing 220 and a mounting surface to which the wiring device 200 is attached (when the wiring device 200 is attached to the wall base 110, the front surface of the wall base 110, and when the wiring device 200 is attached to the wiring tool mounting base 1, will be described later. It is provided to prevent rainwater or the like from entering the housing 220 from the gap with the appliance mounting surface P). The housing 220 is covered with a cover 240 for concealing the screw insertion hole 222 and the like to improve the appearance of the wiring device 200. The cover 240 is formed in a box shape in which the rear surface and the lower surface are opened. The cover 240 is coupled to the housing 220 by sliding in a direction (vertical direction in the present embodiment) intersecting the normal direction of the front surface of the wall base 110.

  The wiring device 200 described above has a rectangular outer peripheral shape (outer size) vertically projected onto the wall base 110 in a state of being installed on the wall base 110, and in the present embodiment, the vertical direction (FIG. 1B). The vertical dimension is 126 mm, and the horizontal dimension (normal direction of the paper surface in FIG. 1B) is 87 mm.

  Next, the wiring fixture mounting base 1 of this embodiment is demonstrated. The wiring device mounting base 1 of this embodiment has a plate-like (rectangular plate-like) base 2 attached to the front surface of the wall base 110 (the left surface in FIG. 1B). As shown in FIGS. 1 to 3, the base 2 is a resin molded product formed using a resin material having insulating properties. As shown in FIG. 4 (a), the thickness of the base portion 2 is such that the rear end surface 241 of the cover 240 of the wiring device 200 is from a plane including the front end surface 121 of the wall member 120 provided on the front surface of the wall base 110. Is also set to a thickness positioned forward. In addition, illustration of the wire penetration hole 111 is abbreviate | omitted in FIG.

  The pedestal 2 is composed of a rectangular plate-shaped (rectangular plate-shaped) front end 20 and a rear end 21 projecting from the rear center of the front end 20. The front end 20 of the pedestal 2 is formed so that the outer peripheral shape vertically projected on the front surface of the wall base 110 is the same as the outer peripheral shape obtained by vertically projecting the wiring device 200 on the front surface of the wall base 110. That is, the outer peripheral shape of the front end 20 of the base 2 is a rectangular shape of 126 mm (vertical dimension) × 87 mm (horizontal dimension), similar to the wiring device 200. Since the outer peripheral shape of the front end part 20 is larger than the rear end part 21 in the base part 2, the outer peripheral shape of the front end part 20 is the outer peripheral shape of the wiring device mounting base 1. In other words, the wiring fixture mount 1 of the present embodiment is formed so that the outer peripheral shape vertically projected on the front surface of the wall base 110 is the same as the outer peripheral shape of the wiring fixture 200 vertically projected on the front surface of the wall base 110.

  In addition, a rectangular recess 20 a is formed in the front center portion of the front end portion 20. In the wiring device mounting base 1 of the present embodiment, the bottom surface of the recess 20a is the above-described device mounting surface (surface that abuts the rear surface of the wiring device 200 on the front surface of the base 2). As shown in FIG. 3, a circular (circular shape in the illustrated example) insertion hole that penetrates the base 2 (that is, the front end 20 and the rear end 21) in the thickness direction is provided at the center of the instrument mounting surface P. 2a is open. The insertion hole 2a is for inserting the electric wire inserted into the electric wire insertion hole 111 of the wall base 110, and the electric wire inserted through the insertion hole 2a is connected to a wiring device 200 attached to the base portion 2. The

  Such a pedestal 2 is attached to the wall base 110 using a plurality of (four in the illustrated example) mounting screws (not shown). Therefore, mounting holes 2b through which threaded portions (not shown) of the mounting screws are inserted are formed at the four corners of the instrument mounting surface P of the base unit 2, respectively. Two mounting holes 2b on the upper side of the pedestal 2 are formed in the shape of a long hole whose longitudinal direction is the width direction of the pedestal 2 (short direction, left-right direction in FIG. 1A). The two mounting holes 2b on the side are formed in the shape of a long hole whose longitudinal direction is the length direction (longitudinal direction, vertical direction in FIG. 1A) of the base portion 2. By the way, the accommodation recessed part 2c is formed in the periphery (opening edge part) of each attachment hole 2b in the front side of the base part 2. As shown in FIG. The housing recess 2c is formed to have a size that can house a screw head (not shown) of the mounting screw without protruding forward from the device mounting surface P. In the present embodiment, the housing recess 2c is formed to a depth of about 5 mm from the instrument mounting surface P.

  A pair of hole portions 2d are formed in the center portion in the width direction of the base portion 2 so as to face each other with the insertion hole 2a therebetween (in the illustrated example, the hole portion 2d is located between the mounting holes 2b in the width direction of the base portion 2). Located in the middle position). The interval between the pair of holes 2d is set equal to the interval between the pair of screw insertion holes 222 of the wiring device 200. The hole 2d is formed so that the front end side is narrower than the rear end side, and the opening shape is different between the front end side and the rear end side. A nut (hexagonal nut in the illustrated example) 3 used for mounting the wiring device 200 is inserted into each hole 2d from the rear end side, thereby constituting a mounting portion for mounting the wiring device 200 on the front side of the base 2. Is done. The inner peripheral shape of the rear end side of the hole 2d is formed in a polygonal shape (regular hexagonal shape in the illustrated example) that can be fixed to the base 2 without rotating the nut 3. Further, the inner peripheral shape on the front end side of the hole 2d is a circular shape (a perfect circular shape in the illustrated example).

  A waterproof rib 2e that prevents fluid (rainwater, etc.) from entering the insertion hole 2a and the like (the insertion hole 2a, the four attachment holes 2b, and the two hole parts 2d) is formed on the device attachment surface P of the base part 2. It is formed. The waterproof rib 2e surrounds the region where the insertion hole 2a, the four attachment holes 2b, and the two hole portions 2d are formed on the device attachment surface P from the upper side of the base portion 2 and both sides in the width direction (the base portion 2). Is formed in a substantially U-shape with the lower side opened. The waterproof rib 2e is unevenly fitted with a fitting groove 231 formed on the rear surface of the waterproof packing 230 of the wiring device 200 when the wiring device 200 is attached to the wiring device mounting base 1, thereby further improving the waterproof property. I am trying.

  The rear end portion 21 of the base portion 2 is formed in a rectangular shape whose outer peripheral shape is the longitudinal direction in the vertical direction. A fitting groove 2f is provided around the rear edge of the rear end portion 21, and the waterproof portion 4 is fitted into the fitting groove 2f. The waterproof part 4 is formed in a rectangular frame shape by a resin material having elasticity (restorability) such as rubber and elastomer. The waterproof part 4 fills a gap between the rear end part 21 of the base part 2 and the wall base 110 and prevents rainwater and the like from entering the insertion hole 2a of the base part 2 and the wire insertion hole 111 of the wall base 110. . By the way, a caulking material is filled between the front end 20 of the base 2 and the wall base 110 (so as to cover the rear surface of the front end 20 and the outer peripheral surface of the rear end 21 and the periphery of the base 2 in the wall base 110). The caulking material 300 is applied) to form a caulking portion 300 as shown in FIG. The caulking part 300 is for filling the gap between the base part 2 and the wall base 110 to prevent rainwater or the like from entering the insertion hole 2 a of the base part 2 or the wire insertion hole 111 of the wall base 110. Here, the surface shape of the outer peripheral surface of the rear end portion 21 of the base portion 2 is a concavo-convex shape formed by forming a plurality of grooves as shown in FIG. 5A (FIG. 1B, FIG. 2, FIG. 3B, FIG. 4, and FIGS. 7 to 9, the concavo-convex shape is omitted), but the rear surface of the front end 20 is a flat surface. In this way, the caulking material is more easily peeled off the outer peripheral surface of the rear end portion 21 than the rear surface of the front end portion 20. Therefore, when the caulking part 300 has changed over time (decreased), as shown in FIG. 5B, the caulking part 300 has an outer peripheral surface of the rear end part 21 before the rear surface of the front end part 20 of the base part 2. Will come off. In addition, as a caulking material used for the caulking part 300, a conventionally well-known thing can be employ | adopted. Further, the surface shape of the outer peripheral surface of the rear end portion 21 is not limited to the above-described uneven shape, and may be, for example, a shape in which a plurality of circular protrusions are provided. Any shape can be used as long as it is easy to peel off.

  The wiring device mounting base 1 of the present embodiment described above is installed on the wall base 110 when or before the wall material 120 is attached to the wall base 110. The wiring device mounting base 1 is installed by screwing the mounting screw to the wall base 110 through the mounting hole 2 b of the base portion 2. After installing the wiring fixture mounting base 1 on the wall base 110 in this manner, the caulking material is filled in the accommodating recess 2 c and in the gaps between the front end 20 and the front surface of the wall base 110. A wall member 120 is installed on the front surface of the wall base 110 so as to surround the wiring fixture mounting base 1. Here, the outer peripheral shape of the base part 2 vertically projected on the front surface of the wall base 110 is the same as the outer peripheral shape of the wiring device 200 attached to the base part 2 vertically projected on the front surface of the wall base 110. By installing the wiring device mounting base 1 in the form on the wall base 110, a space for mounting the wiring device 200 is secured on the wall base 110.

  When attaching the wiring device 200 to the wiring device mounting base 1 installed on the wall base 110, after attaching the housing 220 of the wiring device 200 to the front side of the wiring device mounting base 1, the cover 240 is attached to the housing 220. Adhere. The housing 220 is attached to the wiring device mounting base 1 by screwing the fixing screw into the nut 3 in the hole 2 d of the base 2 through the screw insertion hole 222 of the housing 220. The cover 240 is attached to the housing 220 by sliding the cover 240 up and down with respect to the housing 220. In this case, as shown in FIG. 4A, the thickness of the pedestal 2 is set such that the rear end surface 241 of the cover 240 of the wiring device 200 is the same as the front end surface 121 of the wall member 120 provided on the front surface of the wall base 110. Since the thickness is positioned in front of the plane including the cover 240, when the cover 240 is slid, the cover 240 interferes with the wall member 120 as shown in FIG. 4B (the wall member 120 becomes an obstacle). ), There is no possibility that the cover 240 cannot be coupled.

  As described above, according to the wiring fixture mounting base 1 of the present embodiment, the outer peripheral shape of the base portion 2 vertically projected on the front surface of the wall base 110 is the wiring fixture 200 attached to the base portion 2 of the wall base 110. Since it has the same shape as the outer peripheral shape vertically projected on the front surface, when the wall material 120 is provided on the wall base 110 or before the wall fixture 110 is installed on the wall base 110, the wall base 110 is provided with a wall. Since the place where the material 120 is not provided can be clarified, a space for mounting the wiring device 200 can be easily secured.

  Moreover, since the thickness of the base part 2 is the thickness which positions the rear-end surface 241 of the cover 240 of the wiring device 200 ahead of the plane containing the front-end surface 121 of the wall material 120 provided in the front surface of the wall base 110, When the wiring device 200 is attached to the wiring device mounting base 1, it is possible to prevent the wall material 120 from becoming an obstacle. The thickness of the pedestal 2 may be a thickness in which the front end surface of the pedestal 2 is positioned in front of a plane including the front end surface 121 of the wall member 120 provided on the front surface of the wall base 110. Similarly, the wall material 120 can be prevented from interfering when the wiring device 200 is attached.

  Further, since the waterproof rib 2e protrudes from the front surface (appliance mounting surface P) of the base portion 2, even if there is a defect in the waterproof packing 230 of the wiring device 200 and water enters, the waterproof rib 2e is used. The rib 2e can prevent water from entering the insertion hole 2a, and can prevent fluid (rain water or the like) from entering the wire insertion hole 111 of the wall base 110 through the insertion hole 2a. Moreover, since the accommodation recessed part 2c which accommodates the screw head of the said attachment screw is formed in the periphery of the attachment hole 2b in the front side of the base part 2, the screw head of the said attachment screw does not protrude from the instrument attachment surface P. When the wiring device 200 is attached, the mounting screw can be prevented from becoming an obstacle, and even when a caulking material is applied to fill the mounting hole 2b, the caulking material protrudes from the mounting hole 2b. It can be prevented that it gets in the way when 200 is attached.

  Moreover, since the base part 2 is composed of a plate-like front end part 20 and a rear end part 21 protruding from the center part of the rear surface of the front end part 20, when the base part 2 is installed on the wall base 110. As shown in FIG. 5 (a), a gap is formed between the front end portion 20 and the wall base 110. This gap can be used as a space for filling the caulking material, and the space is filled with the caulking material. By forming the caulking part 300, rainwater and the like can be prevented from entering from the wire insertion hole 111 of the wall base 110, and the waterproofness can be improved. Moreover, since the caulking material is more easily peeled off the outer peripheral surface of the rear end portion 21 than the rear surface of the front end portion 20, when the caulking portion 300 deteriorates with age as shown in FIG. Is peeled off from the outer peripheral surface of the rear end portion 21 before the rear surface of the front end portion 20 of the base portion 2. Therefore, even when the caulking part 300 has deteriorated over time, the caulking part 300 is waterproofed due to peeling from the rear surface of the front end part 20 or the front surface of the wall base 110 before the outer peripheral surface of the rear end part 21 of the base part 2. Sexual deterioration can be suppressed.

  By the way, since the base part 2 is a resin molded product, there is a possibility that sink marks (dents generated on the outer surface of the molded product) may occur. In order to prevent such sinking, a groove portion 2g for preventing sinking may be formed on the front surface of the base portion 2 simultaneously with the injection molding of the base portion 2 as shown in FIG. In the illustrated example, a pair of groove portions 2g are formed on the front surface of the base portion 2 along the length direction of the base portion 2 (vertical direction in FIG. 6). Further, the pair of grooves 2g are formed so as to sandwich the waterproof rib 2e.

  Thus, if the groove part 2g is formed in the base part 2, it can prevent that a sink mark arises in the base part 2. FIG. In addition, the platform 2 shown in FIG. 6 is provided with a communication path 2h that communicates the groove 2g with the outside of the platform 2. The communication path 2h is formed on the lower surface of the pedestal 2, and the direction of opening the communication path 2h to the outside of the pedestal 2 is the vertical direction. Accordingly, when water enters the groove 2g, the water is discharged to the outside of the platform 2 through the communication path 2h.

  That is, in the wiring device mounting base 1 shown in FIG. 6, the front surface of the base portion 2 is provided with a groove portion 2 g for preventing sink marks, and a communication passage 2 h that communicates the groove portion 2 g with the outside of the base portion 2. Since the direction of opening of the communication path 2h to the outside of the pedestal 2 is a vertical direction in a state where the pedestal 2 is installed on the wall base 110, it is possible to prevent the pedestal 2 from being sinked, and to prevent a sink. Since 2 g is also used as a passage for discharging a fluid such as water to the outside, the drainage of the base can be improved with a simple shape. Such a communication path 2h may be any as long as the opening direction to the outside of the pedestal 2 in the state where the pedestal 2 is installed on the wall base 110 is horizontal or downward from the horizontal.

  In addition, the mounting base 1 for wiring devices of this embodiment is one embodiment to the last, and can be changed in the range which does not deviate from the meaning of this invention. For example, the base part 2 of this embodiment has an outer peripheral shape that is perpendicularly projected onto the front surface of the wall base 110, and has the same shape as an outer peripheral shape that is the vertical projection of the wiring device 200 attached to the base part 2 onto the front surface of the wall base 110. However, the present invention is not limited to this, and the wiring device 200 attached to the base part 2 has a shape larger than the outer peripheral shape obtained by vertically projecting the front surface of the wall base (that is, the base part 2 is vertically projected onto the front surface of the wall base 110. The outer peripheral shape may be formed in a shape including an outer peripheral shape obtained by vertically projecting the wiring device 200 attached to the base 2 onto the front surface of the wall base 110. Moreover, although the mounting base 1 for wiring apparatuses of this embodiment assumes the use outdoors, of course, you may use it indoors.
