Abstract
This disclosure is directed to a fool-proof structure having a shelf and a plug-in unit. The shelf is defined with a socket and an opening, and a stopping portion and an actuating portion are provided on the socket, and the actuating portion and the stopping portion are respectively communicated to the opening. The plug-in unit has an elastic arm. A stopping wall and an actuating slope of the elastic arm protrude from the plug-in unit. A first pitch is defined from the actuating portion to the stop portion, and a second pitch is defined from the actuating slope to the stopping wall. The first pitch may be configured to be greater than the second pitch, so that the actuating portion may push the actuating slope to deflect the elastic arm before the stopping wall arrives the stop part when the plug-in unit is inserted into the socket.
