DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the drawings. Note that the present invention is not limited by this.

Embodiment FIG. 1 is an explanatory view showing a relationship between a printed board holder and a printed board according to an embodiment of the present invention. FIG. 1A is an explanatory view showing storage of a printed board, and FIG. (b) is a plan view of the printed circuit board holder holding the printed circuit board, and FIG.
FIG. 3 is a front view of a printed circuit board holder that stores a printed circuit board. 2A and 2B are simple explanatory views showing the configuration of the printed circuit board holder according to the embodiment of the present invention. FIG. 2A is a front view, FIG. 2B is a plan view, and FIG. FIG.

In FIG. 1, reference numeral 1 denotes a printed circuit board holder which is a feature of the present invention. The printed circuit board holder 1 is formed in a substantially U-shape by a mold and has side walls 9, 9.
Inside the bent part 2 and the extruded part 3
One set of 3 is formed in advance by a mold. A torsion portion 5 inserted into a slot 8 provided in the printed circuit board PC from a bottom surface 7 at a position separated from the bent portions 2 and 2 and the extruded portions 3 and 3; At least one substrate fixing / extruding portion 4 including a substrate supporting portion 6 for holding and fixing a PC is provided. Specifically, the dimensions of the printed board holder 1 are 90 mm in length, 36 mm in width,
Is 10.5 mm in height, and the bent portions 2 and 2 having a length of 2 mm and a width of 2 mm and the extruded portions 3 and 3 having a length of 6 mm and a width of 2 mm are respectively 6.5 mm and 4 mm in height from the bottom surface 7. Is formed. The height of the extruded portions 3 and 4 is 4 mm between the back surface of the printed circuit board PC and the bottom surface 7 of the printed circuit board holder 1.
Is set in advance to a value at which an insulation distance from the above is obtained. In addition, the extruded portions 3 and 3 are located diagonally below the bent portions 2 and 2,
The upper and lower gaps between the bent portions 2 and the extruded portions 3 are formed in advance so as to be slightly smaller than the thickness of the printed circuit board PC so that one end of the printed circuit board PC can be easily inserted obliquely from above. It is possible to increase the holding force when the PC is fixed to the substrate fixing / extruding section 4 by the elastic force of the PC. Further, a board supporting part 6 having a height of 4 mm and a width of 8 mm is provided substantially at the center on the bottom surface 7 side of the printed board holder 1 63 mm away from the extruded portions 3 and 3 of the printed board holder 1.
