<p>PURPOSE:To facilitate an execution by mounting on the surface of a building surface. CONSTITUTION:A case 1 is coupled with a mounting frame which is mounted so as to be abutted on the surface of the building surface. In a state that the case 1 is mounted on the mounting frame, the rear surface of the case 1 is positioned on the location which is the same as the rear surface of the mounting frame on in a forward direction of it. A connector to be connected with the terminal part of an electric wire to be a signal line is coupled freely attachably and detachably with the rear surface of the case 1. Therefore, if a hole which is capable of embedding the connector is formed on the building surface, the case 1 can be mounted on the building surface without using an embedded box.</p> |
