A configuration is proposed in which the case 1 is attached to the mounting frame 60 such that the rear surface is located in front of the construction surface. In this structure, the connector 50 for relaying the signal line Ls is provided in the embedding box 4 buried in the construction surface, and the connector 5

It has been proposed that the lead plate 3'is brought into contact with the case 1 to allow transmission of a transmission signal between the adjacent cases 1. As shown in FIG. 17, the conductive piece 71 is fixed to the insulating base 70 fitted to the central piece 67 between the adjacent opening windows 61 of the mounting frame 60, and the tip portion of the lead plate 3 ′ is a case.

う問題が生じる可能性が高くなる。In the above structure, since the insulating base 70 is fitted in the central piece 67 of the mounting frame 60, the width dimension of the central piece 67 and the width dimension of the insulating base 70. It is necessary to substantially match with, and as a result, the width dimension of the conductive piece 71 is also about the same. As a result, the lead plate 3 '
It is necessary to project the lead plate 3 ′ from the side surface of the case 1 so that a part of the front end of the lead frame 3 ′ overlaps a part of the central piece 67 of the mounting frame 60. The lead plates 3 ′ are formed on both side surfaces of the case 1. Even if the lead plate 3 ′ is used for electrical connection with another operation terminal 82 on one side surface of the case, the other side surface of the case 1 is used. In many cases, it is not used for connection with another operation terminal 82. In this case, the unused lead plate 3 ′ faces the peripheral portion of the mounting frame 60, and since the conductive piece 71 has a substantially constant distance from the mounting frame 60, the unused lead plate 3 ′. 'And mounting frame 60
The distance between and is smaller than the distance between the conductive piece 71 and the mounting frame 60, and the unused lead plate 3 ′ easily contacts the mounting frame 60. As a result, when the metal mounting frame 60 is used, the lead plate 3'contacts the mounting frame 60 and the signal line L
There is a high possibility that a problem that the line of s is short-circuited and the transmission signal Vs cannot be transmitted occurs.
