PURPOSE:To achieve economy by providing a printed circuit board with possibility of being inserted and removed in/from a specified position of a back panel depending upon the fixing direction of a guide block, which is to be fixed to the back panel and printed circuit board. CONSTITUTION:Convex surfaces 5A, 6A and concave surfaces 5B, 6B are provided on No.1 and No.2 connector 3, 4 which are inserted and removed while No.1, No.2 guide block 5, 6 to be meshed are confronting. The meshings of these convex surfaces 5A, 6A with concave surfaces 5B, 6B are attained when the fixing direction of the No.1 guide block 5 is in coincidence with that of No.2 guide block 6. Therefore, use of the No.1 and No.2 guide blocks 5, 6 in one set provides a plurality of combinations, and use of a plurality of pieces enables classification of N'th power. Thus it is no more needed to prepare a plurality of insert metal pieces and receptacles differently shaped, which was needed in conventional arrangement, and the simplified constitution leads to accomplishment of economy. |
