基板等の絶縁基板に於ける金属ネジの絶縁構造。[Scope of claim for utility model registration] (1) Insulation of metal screws that secure the creepage distance and spatial distance between the metal screws that screw the mounting bracket of a transformer, etc. onto an insulated substrate such as a printed circuit board, and other live conductors. In the structure, a bush 4 with an insulating flange and a cylindrical part 1b surrounding the side surface of the metal screw head 42a are inserted into the insertion hole 2 of the metal screw 42 into the insulating substrate 43.
An insulating structure for metal screws in an insulating substrate such as a printed circuit board, characterized in that a bushing 1 with an insulating flange integrally provided in a is inserted from the front and back of an insulating substrate 43 and superposed. (2) The scope of the claim for registration of a utility model characterized in that the overlapping portion of the two insulating flanged bushes 1 and 4 is provided with a locking portion 5 consisting of a protrusion 5a and a recess 5b that fit into each other. An insulating structure of metal screws in an insulating substrate such as a printed circuit board as described in item 1.
