Patent ID: 7341458

Claim:
An electric signal transmission connector assembly with magnetically connected receptacle and plug, comprising a plug and a receptacle mounted to a circuit board in an electronic apparatus; the plug including an upper and a lower case that together define an internal space between them to enclose a first magnet, a first transmission assembly, and other metal parts therein; the first transmission assembly including a first circuit board, which is connected to a cable and provided with a plurality of holes; a plurality of first terminals mounted to the holes on the first circuit board; and a first insulating member put around the first terminals to hold the first terminals in place while isolate them from one another; and the first insulating member having a slightly outward protruded top; the first magnet being located around the first insulating member; and the metal parts including a first metal cover and a metal face plate having a predetermined thickness; the first metal cover being downward covered on and around the first magnet, and then welded to an upper side of the first circuit board and the metal face plate being welded to a lower side of the first circuit board; whereby, with the above arrangements, the plug has an upper side formed into a first receiving section and a lower side formed into a first connecting section; and the receptacle including a second metal cover, a second magnet, and a second transmission assembly; the second transmission assembly including a second circuit board having a plurality of holes formed thereon; a plurality of second terminals fitly mounted in the holes on the second circuit board; and a second insulating member put around the second terminals to isolate the second terminals from one another; the second magnet being located around the second insulating member; and the second metal cover being connected to the second transmission assembly; whereby, with the above arrangements, the receptacle has an upper side formed into a second receiving section for the first connecting section on the plug to connect thereto, and a lower side connected to the circuit board in the electronic apparatus.
