1. An electrical connector assembly for a neural monitoring device, the electrical connector assembly comprising:
(a) an electrode interface board comprising a first printed circuit board with a top surface and a bottom surface, wherein a socket portion of a subminiature dual-row electrical connector is attached to the top surface of the first printed circuit board, wherein a first plurality of magnets is attached to the bottom surface of the first printed circuit board, and wherein the socket portion comprises a plastic housing and a plurality of female contacts, each female contact comprising a protruding contact point; and (b) a head stage comprising a top socket connector and a second printed circuit board with a top surface and a bottom surface, wherein a plug portion of a subminiature dual-row electrical connector is attached to the bottom surface of the second printed circuit board, wherein a second plurality of magnets is attached to the bottom surface of the second printed circuit board, wherein each magnet has a height, wherein the height of all of the magnets in the second plurality of magnets is the same, wherein the plug portion comprises a plastic housing and a plurality of male contacts, each male contact comprising a detent, and wherein each of the male contacts in the plurality of male contacts is electrically connected to the top socket connector via a through-board connection; wherein the male contacts of the plug portion mate with the female contacts of the socket portion so that the protruding contact point of each female contact touches an inside distal surface of a male contact, and wherein the height of the magnets in the second plurality of magnets prevents the male contacts from seating further into the female contacts; wherein the protruding contact point of each female contact does not travel far enough to snap into the detent of the male contact. |
