Claims

[Claims for Utility Model Registration] 1. In an electronic device comprising a housing 11 with a two-part structure consisting of a pair of cases 12 and 13, and a printed wiring board 14 housed in the housing 11, one of the cases 12 includes: A plurality of support seats 16 are provided on which printed wiring boards 14 are placed, and each support seat 16 has a plurality of slits that have spring properties, bulge in the radial direction at the middle portion in the longitudinal direction, and extend in the longitudinal direction. A cylindrical projection 18 having a diameter of 19 is provided, and a corresponding cylindrical projection 18 is provided on the printed wiring board 14.
The other case 13 is provided with a plurality of fitting parts 21 that can be fitted into the corresponding cylindrical protrusions 18, and the cylindrical protrusions 18 are fitted with a printed wiring board. When the mounting holes 20 of 14 and the fitting portions 21 are fitted, the cylindrical protrusion 18 comes into pressure contact with the mounting holes 20 and the fitting portions 21, so that the pair of cases 12, 13 and the printed wiring board 14 are integrated. A printed wiring board mounting structure for electronic equipment, characterized in that it is fixed to a printed wiring board. 2. The fitting part 21 has a fitting projection 22 that expands the diameter of the cylindrical projection 18 by fitting inside the cylindrical projection 18 against the spring force. The outer surface of the cylindrical projection 18 is the printed wiring board 1
Printed wiring for an electronic device according to claim 1, wherein the wiring is pressed against the inner surface of the mounting hole 20 of No. 4, and the inner surface of the cylindrical projection 18 is pressed against the outer surface of the fitting projection 22. Board-mounted structure. 3. The fitting part 21 has a fitting hole 23 that receives the cylindrical projection 18, and the entrance of the fitting hole 23 and the inner diameter of the mounting hole 20 of the printed wiring board 14 correspond to the cylindrical projection 1.
The diameter is smaller than the maximum outer diameter of the middle part of 8.
When the cylindrical projection 18 is fitted into the mounting hole 20 and the fitting hole 23, the diameter is reduced against the spring force, and
When the cylindrical projection 18 is completely fitted into the mounting hole 20 and the fitting hole 23, the spring force causes the cylindrical projection 18 to
The printed wiring board mounting structure for an electronic device according to claim 1, wherein the outer surface of the printed wiring board 14 is pressed against the inner surface of the mounting hole 20 and the inner surface of the fitting hole 23 of the printed wiring board 14.
