Claims

[Claims for Utility Model Registration] 1. In a positioning structure for connecting printed circuit boards, the first printed circuit board has a positioning copper foil near the connection part, and the positioning copper foil has a straight part. has a first arcuate portion consisting of either an arcuate convex portion or an arcuate recess with radius r in a portion adjacent to the first printed circuit board, and is in a predetermined positional relationship with the first printed circuit board; A concentric circle of the circular arc portion is placed on a portion adjacent to the outer straight portion at a position corresponding to the first circular arc portion so as to face the first circular arc portion and not overlap with the first circular arc portion. a second arc-shaped portion consisting of either an arc-shaped concave portion having a radius somewhat larger than the radius r and a circular convex portion having a radius somewhat smaller than the radius r; The linear portion of the positioning copper foil and the outer linear portion of the second printed circuit board are in a parallel relationship such that there is an equally spaced gap at at least one location when both the printed circuit boards are in a predetermined positional relationship. A printed circuit board positioning structure characterized by: 2 The positioning copper foil provided on the first printed circuit board and the reinforcing copper foil provided around the circular arc-shaped portion formed at the position corresponding to the positioning copper foil in the second printed circuit board 2. The printed circuit board positioning structure according to claim 1, wherein the positioning copper foil and the reinforcing copper foil form one round shape when both the printed circuit boards are in a predetermined positional relationship. 3. The printed circuit board positioning structure according to claim 1, wherein the second printed circuit board is geometrically connected to the first printed circuit board at a portion other than the connecting portion.
