This configuration enables reliable connection and reliable connection maintenance, but on the other hand, when the terminals of the electrical contact part are inserted and removed, the contact resistance gradually increases due to wear of the electrical contact part, resulting in electrical connection loss. It can occur. Further, since the electric contact portion and the magnet portion are separated from each other, the attractive force of the magnet does not act on the connection itself of the electric contact portion, and the magnetic force does not sufficiently act from the viewpoint of connecting the electric contact portion. Such issues can be considered.
Patent Document 2 similarly discloses a configuration in which a magnet assists the fitting of the connectors, but when the connectors are released from the fitting, the connectors must be pulled out against the attractive force of the magnetic force, so that the operability is operability. There is a possibility that a large amount of friction may occur in the terminal part because it is pulled out with a strong force.
