Abstract:
A connection device having a switch, the device comprising a base mountable on a portable appliance fitted with a first antenna and a plug adapted to be connected to a second antenna, said base being suitable for being connected to said plug, wherein said base comprises:an axial conductor adapted to be connected to a circuit of said portable appliance;a first cylindrical conductor substantially coaxial about said axial conductor, insulated from said axial conductor, and adapted to be connected to said first antenna;a second cylindrical conductor surrounding said first cylindrical conductor and insulated therefrom, said second cylindrical conductor being adapted to be connected to a ground connection of said portable appliance; anda resilient electrical switch member that is circularly symmetrical about the axis common to the cylindrical conductors, having a first end secured to one of two elements constituted by the first cylindrical conductor and the axial conductor, and having its second end when at rest in contact with the other one of said two elements;and wherein said plug comprises:a hollow axial first conductor suitable for cooperating with the axial conductor of the base, said hollow conductor being adapted for connection to said second antenna;a cylindrical second conductor surrounding said hollow first conductor substantially coaxially, and adapted to be connected to the shielding of said second antenna; andmechanical insulating means for holding the second end of the switch member away from its rest position when said plug is engaged in said base, whereby, when said plug is engaged in said base, the hollow first conductor of the plug comes into resilient contact with the axial conductor of the base and the mechanical insulating means hold off the second end of the switch member, and said cylindrical second conductor of the plug comes into electrical contact with at least said second cylindrical conductor of the base.
