In another example embodiment, the first magnetic coupler 22 is a magnet, preferably a permanent magnet, and the second magnetic coupler 32 is also a magnet, preferably a permanent magnet. The pole of the magnet on the male edge connector 20 and the pole of the magnet on the female connector 30 are arranged (e.g., position) so that the magnet on the PCB 10 is attracted to the magnet on the female connector 30. Because the magnets are attracted to each other, the force between the magnet on the PCB 10 and the magnet on the female connector 30 (e.g., the first force of attraction) retains the male edge connector 20 in the female connector 30.

The force that retains the male edge connector 20 in (e.g., connected to) the female connector 30 (e.g., first force of attraction, second force of attraction) is proportional to the magnetic force provided by the magnet. A magnet may provide a magnetic force of attraction of sufficient strength (e.g., magnitude) to retain the male edge connector 20 inserted into the female connector 30 and the pins 26 connected to the pins 36 under normal circumstances of use.
