Claims

[Claims for Utility Model Registration] 1. A printed circuit board on which electronic components are mounted is attached to the inner surface of a chassis constituting a housing of an electronic device with a space between the chassis and the printed circuit board and the chassis. The structure is such that an insulating plate is attached, wherein the chassis is provided with a cut-and-raised piece, a notch or hole is provided in the cut-and-raised piece near the plate surface of the chassis, and an opening is provided in the insulating plate through which the cut-and-raised piece is passed. established,
Engaging the edge of the opening or the protruding piece provided on the edge with the notch or hole of the cut-and-raised piece,
A convex portion (or concave portion or hole) provided on the plate surface of the insulating plate is elastically fitted into a concave portion or hole (or convex portion) provided on the plate surface of the chassis due to the elasticity of the insulating plate. Insulating board mounting structure. 2. In claim 1, a protrusion is provided in place of the notch or hole provided in the cut-and-raised piece, and the edge of the opening provided in the insulating plate is fitted between the protrusion and the plate surface of the chassis. Features an insulating board mounting structure. 3. The insulating board mounting structure according to claim 1 or 2, wherein the cut and raised piece is also used as a mounting piece for a printed circuit board. 4. A structure in which a printed circuit board on which electronic components are mounted is mounted on the inner surface of a chassis constituting a housing of an electronic device at a distance from the chassis, and an insulating plate is installed between the printed circuit board and the chassis. , a plurality of cut-and-raised pieces or cut-and-raised portions are provided at locations corresponding to the periphery of the insulating plate of the chassis, and the periphery of the insulating plate is slidably engaged with the cut-and-raised pieces or the cut-and-raised portion; Convex portions provided on the plate surface (
An insulating plate mounting structure characterized in that a recess or hole (or concave or hole) is elastically fitted into a concave or a hole (or a convex) provided in a plate surface of the chassis due to the elasticity of the insulating plate.
