Abstract

A magnetic connector assembly prevents magnets from making an interference in signal transmission of terminals and prevents incorrect insertion. The magnetic connector assembly includes a first connector and a second connector. The first connector includes a fixed case, and a first plastic body with a jointing groove is disposed outside the fixed case. A circuit board with a first PIN module is disposed inside of the fixed case. The second connector includes a second PIN module disposed on a second plastic body with an inner case. An inserting part is disposed on one end of the inner case far away from the second plastic body. When the first connector and the second connector are jointed, the inserting part of the inner case is inserted into the jointing groove.
