Further, a display 68 for explanation is provided in the vicinity of each of the openings 64 and 65. In addition, the support attachment portions 56 on both sides are formed with a plurality of claw portions 70 projecting outward from each other and fitting windows 71 recessed in the inner direction.

  Further, each support mounting portion 56 penetrates in the front-rear direction, and is located diagonally at the upper left corner and the lower right corner in the front view, and constitutes a fastening receiving portion. Holes 72 and 73 are formed.

  Furthermore, 75 and 75 are assembly screws as fasteners, and these screws 75 are respectively inserted into the mounting holes 72 and 73 of the cover body 22 from the front side and screwed into the screw holes 45 and 46 of the main body 21. The main body 21 and the cover body 22 are fastened to each other and firmly fixed. That is, these screws 75 are diagonally located at the upper left corner and the lower right corner in front view according to the positions of the screw holes 45 and 46 and the mounting holes 72 and 73, respectively. And the cover body 22 are connected to each other.

  The wiring device 10 covers the opening of the component storage unit and attaches the cover body 22 to the component storage unit of the main body 21 in a state where each component is stored. Then, the engaging portions 61 provided at two positions of the cover body 22 are engaged with the engagement receiving portions 41 provided on the main body 21, respectively, and the cover body 22 is attached to the main body 21. Further, the screw 75 is inserted into the mounting holes 72 and 73 of the cover body 22 from the front side, and is screwed into the screw holes 45 and 46 of the main body 21 to be tightened, whereby the main body 21 and the cover body 22 are firmly connected. Then, the wiring device 10 is assembled.

  The wiring device 10 configured in this manner is attached to the support by engaging the claw portion 70 of the support mounting portion 56 with the resin support, and through this support, such as an indoor wall surface of a house Installed in the construction. Also, in this wiring device 10, a telephone subscriber line, which is a so-called telephone line, is connected to the input terminal portion 48 on the back side, and a feed wiring led to another room of the house is connected to the feed terminal portion 49. Connected to form a wiring device. Note that, with the wiring device 10 attached to the support, the head of the screw 75 is covered with the support, and the screw 75 is prevented from coming off. Further, when the support is made of metal, the engaging portion protruding from the support is engaged with the fitting window 71 of the support attaching portion 56.

  As shown in FIG. 5, the wiring device 10 of the wiring device installed in this way is connected to the first modular jack 11 for the telephone, and the modular plug connected to the telephone 77 is connected to the wiring apparatus 10 as necessary. Accordingly, the modular plug connected to the splitter 78 is connected to the second and third modular jacks 12 and 13. Further, a connection device 79 such as an ADSL modem is connected to the splitter 78, and a computer 80 is connected to the connection device 79.

  Therefore, when only the telephone signal is input / output to / from the telephone subscriber line, the switch 14 is switched to the state indicated by the broken line in FIG. Then, the telephone subscriber line is connected to the telephone connected to the first modular jack 11 via the wiring device 10 and to the telephone connected via the feed terminal portion 49. Further, when a signal such as DSL for Internet connection is superimposed on the telephone subscriber line, the switch 14 is switched to the state indicated by the solid line in FIG. Then, the telephone subscriber line is first connected to the splitter 78 from the third modular jack 13 serving as a line input / output, and the splitter 78 separates the telephone signal and the DSL signal. Then, the telephone signal is returned from the second modular jack 13 to the wiring device 10, and the telephone connected to the telephone connected to the first modular jack 11 and the telephone connected to the first modular jack 11 from the wiring device 10. Connected. On the other hand, a DSL signal is connected to a computer 80 via a connection device 79 such as an ADSL modem, and the computer 80 can be connected to the Internet.

  According to the wiring device 10 of the present embodiment, the resin main body 21 and the resin cover body 22 are combined by engagement at only two places, and the casing is mounted using only two screws 75. Compared to a conventional configuration using caulking metal fittings or a configuration in which a large number of locations are engaged, the structure can be simplified and the manufacturing cost can be reduced.

  Further, with respect to the four corners of the wiring device 10, that is, the main body 21 and the cover body 22, the engaging portions of the engaging portion 61 and the engagement receiving portion 41 are diagonally set with respect to the center of the wiring device 10 in a front view. Since the screw 75 is arranged on the other diagonal, that is, on the side where the engagement portion is not provided, with respect to the center of the wiring device 10 in front view, the main body 21 and the cover body 22 are fixed to each other. The absolute strength to be secured can be easily secured by the screw 75 and can be held so that the engaging portion between the main body 21 and the cover body 22 is not disengaged even when a force is applied from the outside.

  Furthermore, since the screw 75 is positioned at the outermost corner of the wiring device 10 and the engaging portion is positioned in the vertical direction, that is, slightly in the center and back side of the outermost contour of the wiring device 10, the wiring device 10 It is possible to prevent the engaging portion from coming off by receiving a twisting force applied to the screw 75 with the screw 75. The engaging portion between the engaging portion 61 and the engaging receiving portion 41 can be provided, for example, in the vertical direction of the wiring device 10, that is, the central portion in the longitudinal direction.

  Further, the main body 21 and the cover body 22 can be brought into close contact with each other by combining the screw 75 with the elastic engagement of the resin, as compared with the configuration in which the main body and the cover body are assembled with only the minimum necessary screws. Therefore, a gap between the main body 21 and the cover body 22 due to warpage, sink marks, or the like generated during the manufacture of the resin component is unlikely to occur, and the appearance can be improved.

  Further, since a conventional caulking fitting is not used, a dedicated tool is not required for assembly, and the wiring device 10 can be assembled using only a general tool, so that the manufacturing cost can be reduced.

  This configuration is effective for two or more module sizes that increase the size of the wiring device. In particular, the three-module wiring device 10 is effective in that it can secure the strength while simplifying the structure. It can also be applied to a one-module size wiring device.

  Further, by using this wiring device 10, compared with a configuration using a so-called information distribution board having a LAN hub or terminal block, the structure can be simplified, the initial cost can be reduced, and the hub can be replaced freely. . Standardized general support and embedded wiring device parts such as plates can be used to improve versatility, reduce manufacturing costs, and make installation work easier and reduce installation costs Can be reduced.

  The present invention can be applied to, for example, a wiring device that is embedded in a wall surface using a support.
