1. A magnet connector which allows a plug connector, inserted into a receptacle connector, to be attracted to the receptacle connector and held in a connected state by a magnetic force,wherein the receptacle connector comprises:

  • a receptacle housing having a recessed portion that has a bottom surface and an inner wall surface perpendicular to the bottom surface;

    a receptacle connecting surface as the bottom surface;

    a receptacle contact provided at the receptacle connecting surface; and

    a first receptacle magnetic pole portion provided on the receptacle connecting surface,wherein the plug connector comprises;

    a plug housing adapted to be inserted into the recessed portion of the receptacle connector;

    a plug connecting surface, as an insertion front surface of the plug housing, adapted to be connected to the receptacle connecting surface of the receptacle connector;

    a plug contact provided at the plug connecting surface; and

    a first plug magnetic pole portion provided on the plug connecting surface at a position adapted to face the first receptacle magnetic pole portion of the receptacle connector,wherein the recessed portion allows for a position offset of the plug connector in a direction crossing a connector connecting direction within a movement range limited by the recessed portion,wherein a biasing means is provided on a side of one of the receptacle contact and the plug contact,wherein the first receptacle magnetic pole portion and the first plug magnetic pole portion have opposite magnetic polarities,wherein the receptacle connector further comprises;

    a first receptacle wall surface as the inner wall surface;

    a second receptacle magnetic pole portion provided on the first receptacle wall surface in a region thereof close to the receptacle connecting surface; and

    a third receptacle magnetic pole portion provided on the first receptacle wall surface in another region thereof farther from the receptacle connecting surface compared to the second receptacle magnetic pole portion,wherein the plug connector further comprises;

    a first plug side surface which faces the first receptacle wall surface when inserted into the receptacle connector;

    a second plug magnetic pole portion provided on the first plug side surface in another region thereof close to the plug connecting surface; and

    a third plug magnetic pole portion provided on the first plug side surface in another region farther from the plug connecting surface compared to the second plug magnetic pole portion,wherein the second receptacle magnetic pole portion and the third receptacle magnetic pole portion have opposite magnetic polarities,wherein the second plug magnetic pole portion and the third plug magnetic pole portion have opposite magnetic polarities,wherein the second receptacle magnetic pole portion and the second plug magnetic pole portion have opposite magnetic polarities, andwherein the biasing means has a retraction margin such that the plug contact is brought into contact with the receptacle contact when the second plug magnetic pole portion faces the third receptacle magnetic pole portion and the plug connecting surface is not brought into contact with the receptacle connecting surface.
