Abstract

Abstract A modular fitting open slit, which is open at its rear end part, for freely inserting a modular plug into and removing it from said modular fitting open slit is provided at a rear end part of a modem card, and said open slit is provided with inner walls which function as a guide part for setting a direction of insertion of a modular plug, an extreme end position setting part for positioning an extreme end of said modular plug which is inserted, a return prevention part for engaging with said modular plug inserted to prevent it from coming off and terminals which function as a terminal connecting part which is electrically connected to the terminals of the modular plug. Said open slit is provided with L-shaped guide members for guiding insertion of said modular plug with their base sides set to be pivotally turnable and said guide members are formed to be freely remountable in said open slit. For inserting the modular plug into the open slit, the guide members are turned to make their L-shaped inner walls serve as the guide surfaces for positioning insertion of the modular plug. Thus the present invention enables to easily and accurately insert the modular plug insert into said open slit and provide a communication card which is not obstructive even when it is kept loaded in a personal computer or the like.
