Claims

[Claims for Utility Model Registration] (1) A ground terminal formed by fixing a ground terminal fixed to the printed circuit board to a casing that houses the printed circuit board, and electrically connecting the casing and the printed circuit board. In the connection structure, a guide space is formed in the ground terminal in a direction in which the printed circuit board is inserted into the casing, and an insertion part inserted into the guide space of the ground terminal is formed in the casing; A connecting member having an abutting portion that abuts and prevents insertion of the insertion portion beyond a predetermined value is provided, and a terminal side screw hole is formed in the ground terminal, and further,
An insertion part side screw hole is formed in the insertion part of the connection member, and the insertion part side screw hole communicates with the terminal side screw hole of the ground terminal when the contact part of the connection member comes into contact with the ground terminal, and the insertion part side screw hole communicates with the terminal side screw hole of the ground terminal. An earth terminal connection structure characterized in that a screw member is inserted into the insertion part side screw hole, and the connection member and the earth terminal are screwed together. (2) The terminal-side screw holes of the ground terminal and the insertion-side screw holes of the insertion section should be arranged so that when the printed circuit board is stored vertically in the case, the screw members are approximately perpendicular to the printed circuit board. Claim 1 formed
Earth terminal connection structure as described. (3) The earth terminal connection structure according to claim 1 or 2, wherein the distal end of the insertion portion of the connecting member has a tapered surface whose width becomes narrower toward the distal end so that the insertion portion of the connecting member can be easily inserted into the guide space of the earth terminal. . (4) The guide space of the ground terminal has a tapered surface whose width narrows from the entrance toward the back so that the insertion portion of the connecting member can be easily inserted.
Earth terminal connection structure described in 2 or 3.
