<p>PURPOSE:To ensure electric non-conductance of a metal support installation section for installing an electric appliance by insulating the installing surface electrically in clamping an installation section with an insulating bushing from both sides to fix an appliance installation frame to the installation surface inserted with screws, etc. CONSTITUTION:An insulating bushing 5 has a U-shaped cross section coupled with two insulating plates 5a and 5b at one end and insulates an installation section 2 of a metal support 1 clamped from both sides. To the bushing 5 a long hole 6 and a round hole 7 are provided corresponding to an installation hole 3 by the metal support 1 and a screw hole 4 for installing a decorative sheet. A projection 8 for anchoring and holding the bushing on both ends of the insulation plate 5b at the back is provided. In installation, while the installation plates 5a and 5b are extended as shown with an arrow b, the insulation section 2 of the metal support 1 is clamped and installed as shown with an arrow A. To this metal support 1 e.g. a dimmer is installed.</p> |
