Claims

[Scope of utility model registration request]

Multiple modules (modularized electronic circuits) consisting of electronic circuit printed wiring boards, guide rails attached to the upper and lower sides, a surface panel at one end of the board, terminal plugs, etc. are placed in a storage rack. In a system formed by inserting each module along the grooves provided and connecting them to the connectors of the rack, a rectangular vane is used to fix each of the above modules on the front of the rack and to maintain the ground potential. Before mounting the bent elastic leaf spring on the module rack, the front surface is curved in a convex shape and lies flat on the top surface of the bar, but when the module is mounted on the rack, the convex surface is curved in the shape of a convex surface on the front panel of each module. By screwing in the fixing bar fixing screws, the fixing bar is forced into surface contact with the back surface of the panel of the module, and as it becomes flat, the top surface of the bar is lifted upward by the spring elasticity and comes into pressure contact with the guide rail of each module. A device for preventing external noise from entering a module mounted on a rack, characterized in that the module is mounted in a rack.
