A side opening 130 shown in FIG. 3 is formed on the bottom surface side of the housing 110. When the cable is routed along the wall surface, the opening cover 132 is removed and the cable is passed through the side opening 130. When the cable is routed inside the wall, the opening cover 132 covers the side opening 130 to reduce the ingress of dust into the housing 110.

The mounting bracket 134 and the terminal cover 138 shown in FIG. 4 are attached to the lower case 114 of the housing 110. The mounting bracket 134 is fixed to the wall surface on which the remote control device 100 is mounted to support the housing 110. The mounting bracket 134 includes a back opening 136 through which a cable passes when wired in the wall. The terminal cover 138 is fixed to the lower case 114 and covers the connection terminal to which the cable is connected.

FIG. 5 is a rear view of the remote controller device 100 with the mounting bracket 134 and the terminal cover 138 removed. The lower case 114 of the housing 110 includes a terminal storage portion 140, a cable storage groove 150, a cable connection groove 160, and a cable wiring groove 190. The terminal accommodating portion 140 and the grooves 150, 160, 190 are formed so as to be recessed toward the upper case 112, respectively.

The terminal storage unit 140 stores the electrical equipment terminal 142 and the peripheral device terminal 144 as connection terminals. The cable storage groove 150 stores the cable to be wired to the terminal storage portion 140 through the side opening 130 or the back opening 136 of the mounting bracket 134. In addition, the cable to be wired in the cable connection groove 160 through the rear opening 136 is stored. The cable connection groove 160 houses a cable connected to the connector terminal 162 as a connection terminal.

The wiring structure of the cable in the remote controller 100 will be described with reference to FIGS. 6 to 8. As shown in FIG. 6, the lower side wall 152 of the cable storage groove 150 is formed with a first bent surface 154 and a second bent surface 156. The first bent surface 154 bends from the side opening 130 toward the electrical equipment terminal 142. The second bent surface 156 is formed on the side opening 130 side of the first bent surface 154, and bends from the cable connection groove 160 toward the back opening 136 (not shown in FIG. 6). The first bent surface 154 is a convex surface that bulges toward the upper side wall 158 of the cable storage groove 150. The second bent surface 156 is a concave surface recessed with respect to the upper side wall 158.

The support piece 180 is formed at a position along the extension line of the first bent surface 154 and facing the second bent surface 156. The support piece 180 includes a flat plate portion 182 and protrusions 184 and 186. The flat plate portion 182 extends from the bottom surface of the cable storage groove 150 toward the back surface side of the remote control device 100, and bends along the extension line of the first bent surface 154. The projecting portions 184 and 186 project from the side end portions of the flat plate portion 182 toward the second bent surface 156, respectively.

A third bent surface 164 is formed on the upper side wall 158 of the cable storage groove 150. The third bent surface 164 bends from the side opening 130 toward the peripheral device terminal 144. The third bent surface 164 is a concave surface recessed with respect to the lower side wall 152.

The cable wiring groove 190 is defined by a lower opening wall 192 and an upper storage wall 194. The opening wall 192 connects the side opening 130 to the cable connection groove 160. The storage wall 194 is connected from the cable storage groove 150 to the cable connection groove 160. The storage wall 194 bends along an extension line of the second bent surface 156 of the cable storage groove 150. A partition piece 196 is formed in the cable wiring groove 190. The partition piece 196 extends from the bottom surface of the cable wiring groove 190 to the back surface side of the remote control device 100, and forms a wiring path through which the cable passes between each of the opening wall 192 and the storage wall 194.

FIG. 7 is a diagram showing a state in which a cable is routed from the side opening 130. When the cable is routed along the wall surface to which the remote control device 100 is attached, the cable is connected to the connection terminal through the side opening 130. In the present specification, the wiring form in which the cable is exposed from the remote controller 100 to the indoor side of the wall is referred to as exposed wiring.

As shown in FIG. 7, a maximum of four cables 10 are wired in the remote controller 100 in this embodiment. The cable 10a is a connecting line with the electrical equipment 1000. The cable 10a is wired along the first bent surface 154 of the lower side wall 152 of the cable storage groove 150 and the upper surface of the flat plate portion 182 of the support piece 180. The support piece 180 supports the cable 10a so as to prevent the cable 10a from bending to the opposite side at a position facing the second bent surface 156 and to maintain a bending radius along the first bent surface 154. Therefore, it is possible to reduce the load due to wiring and prevent the cable 10a from being damaged and deteriorating in performance. Further, when the cable 10a is routed, it can be arranged without applying a large load, so that the wiring work can be easily performed.

The cables 10b and 10c are connection lines with peripheral devices of the electrical equipment 1000. The cable 10b is wired along the third bent surface 164 of the upper side wall 158 of the cable storage groove 150. The cable 10c is wired along the lower side wall 152 side of the cable 10b. By routing the cables 10b and 10c in order along the third bent surface 164, the load applied to each cable can be reduced as in the case of the cable 10a.

The cable 10d is a LAN (Local Area Network) cable connected to the connector terminal 162. The remote controller 100 connects to the Internet via the cable 10d and transmits and receives various data to and from the service center. The cable 10d includes a connector 12 that is inserted into and removed from the connector terminal 162, and is wired through between the partition piece 196 and the opening wall 192 of the cable wiring groove 190. The opening wall 192 bends from the cable connecting groove 160 toward the side opening 130. By wiring along the opening wall 192, the load applied to the cable 10d can be reduced like other cables.

Here, the cable is gently curved in the first bent surface 154 and the second bent surface 156 of the lower side wall 152 of the cable storage groove 150, the third bent surface 164 of the upper side wall 158, and the opening wall 192 of the cable wiring groove 190. Increase the radius of curvature as much as possible. Specifically, the diameter is four times or more the diameter of the cable routed along each cable. As a result, the load applied to each cable 10 can be reduced more reliably, and damage and performance deterioration can be suppressed.

FIG. 8 is a diagram showing a state in which a cable is routed from the back opening 136. When cables are routed from within the wall to which the remote control device 100 is mounted, each cable is connected to a connection terminal through a rear opening 136. In the present specification, the wiring form in which the cable is routed from inside the wall in this way is referred to as in-wall wiring. The wiring inside the wall improves the appearance because the cable is not exposed to the indoor side of the wall.

In the wiring inside the wall, the cable 10d is connected to the connector terminal 162 and is wired in a semicircle from the cable connection groove 160 through the cable storage groove 150 to the rear opening 136. The cable 10d passes between the storage wall 194 and the partition piece 196 in the cable wiring groove 190. Further, in the cable storage groove 150, the cable storage groove 150 passes between the second bent surface 156 of the lower side wall 152 and the protruding portions 184 and 186 of the support piece 180. The storage wall 194 of the cable wiring groove 190 bends along the extension line of the second bent surface 156. By routing the cable 10d along the second bent surface 156 and the storage wall 194, the wiring inside the wall can be wired without being excessively bent. Therefore, the same effect as the exposed wiring can be obtained. Further, by setting the radius of curvature of the second bent surface 156 and the storage wall 194 to be four times or more the diameter of the cable 10d, the load applied to the cable 10d can be reduced more reliably. Further, the cable 10d can be easily arranged by passing it between the support piece 180 and the second bent surface 156, which facilitates the wiring work and improves the work efficiency.

Next, the structure of the cable connection groove 160 will be described with reference to FIGS. 9 and 10. FIG. 9 is an enlarged view of the cable connection groove 160. FIG. 10 is a cross-sectional view taken along the line AA of FIG. The state in which the cable 10d is wired inside the wall will be described, but the same applies to the exposed wiring. The cable connection groove 160 extends in the direction of pulling out the cable 10d from the connector terminal 162, and houses the cable 10d connected to the connector terminal 162. The cable connection groove 160 includes a terminal connection portion 170 and a recess portion 172.

The terminal connection portion 170 is formed between the connector terminal 162 and the wiring opening 174 leading to the cable wiring groove 190, and houses the cable 10d to be inserted and removed from the connector terminal 162.

The recessed portion 172 is formed so as to face the connector terminal 162 and leads to the lower side of the terminal connecting portion 170. The recessed portion 172 is formed up to a position away from the connector terminal 162 from the wiring opening 174. With this configuration, when the cable 10d is inserted into and removed from the connector terminal 162, a finger can be inserted into the recessed portion 172 to easily perform wiring work. When the remote control device 100 is miniaturized and the size of the terminal connection portion 170 cannot be sufficiently secured, the recessed portion 172 is effective in improving the workability of wiring.

The recessed portion 172 is formed in a tapered shape whose width becomes narrower as the distance from the connector terminal 162 increases. Further, as shown in FIG. 10, the depth D1 of the recessed portion 172 is smaller than the depth D2 of the terminal connecting portion 170. With this configuration, a space for mounting components on the printed circuit board 176 and a space for forming a fixed structure between the upper case 112 and the lower case 114 can be secured in the housing 110. This is effective when the remote control device 100 is downsized.

As described above, according to this embodiment, it is possible to provide a housing 110 to which cables can be appropriately routed and a remote controller 100 including the housing 110. By wiring the cable along one of the bent surfaces, it is possible to prevent the cable from bending excessively, reduce the load, and suppress damage and performance deterioration of the cable. Since the cable can be easily arranged by routing it along the bent surface, wiring work can be easily performed. In addition, a bent surface corresponding to the exposed wiring and the wiring inside the wall is formed, and the cable can be appropriately routed in both wiring forms. Further, a recessed portion 172 is formed in the cable connecting groove 160, so that the wiring work between the cable and the connector terminal 162 can be easily performed.
