The electrical connection device 101 is magnetically mated with the electrical connector 102. The electrical connection terminal 23 is connected to the electrical connection arm 21, and the electrical connection arm 21 is located between the magnetic member 22 and the electrical connection terminal 23. After the magnetic member 22 is matched with the electric connector in place under the action of magnetic attraction, the magnetic member 22 pushes the electric connecting arm 21, so that the electric connecting terminal 23 is fully electrically contacted with the electric connector. Because each electric connection arm 21 is independently arranged, namely the electric connection terminals 21 and the magnetic pieces 22 are independently matched, the single magnetic piece 22 independently pushes the corresponding electric connection terminal 23, and therefore the optimization of the electric connection reliability of the single electric connection terminal 21 is achieved. Therefore, when the magnetic electrical connection is performed, the electrical connection of the respective electrical connection terminals 23 is independent and does not affect each other, and the reliability of the connection between the electrical connection device and the electrical connector is improved.

One end of the elastic arm 212 is connected to the electrode pad 211, the other end of the elastic arm 212 extends and is connected to the bus structure 30, and the size of each placement groove 112 is adapted to the size of the corresponding elastic arm 212.
Referring to fig. 1 to 3, optionally, the terminal assemblies 20 are arranged in pairs and a plurality of pairs are provided, and at least one pair of terminal assemblies 20 is used for data communication.

The elastic arms 212 of the pair of terminal assemblies 20 as a means for charging the mobile phone may be widened so that the terminal assemblies 20 may withstand a large current flow therethrough to support rapid charging of the mobile phone. When the terminal assembly 20 for charging is used in plural pairs, the reliability of the connection between the electric connection device 101 and the electric connector 102 can be further improved. It will be appreciated that when the plurality of pairs of terminal assemblies 20 are used for data communication, the reliability of data communication in the handshake protocol may also be improved.
Optionally, the pair of terminal assemblies 20 may also perform other data communication, such as when the mobile phone is connected to the computer through the electrical connection device 101, the data exchange between the mobile phone and the computer may be realized through the pair of terminal assemblies 20.
Alternatively, any pair of the two terminal assemblies 20 are axisymmetric about the same straight line of symmetry. The two terminal assemblies 20 of each pair are disposed on two sides of the symmetrical line, respectively, so as to facilitate mating with the electrical connector 102.
Alternatively, the positive and negative polarities of the electric connection terminals 23 located on the same side of the symmetrical line are the same, i.e., the electric connection terminal 23 with positive polarity is located on one side of the symmetrical line, and the electric connection terminal 23 with negative polarity is located on the other side of the symmetrical line.
Alternatively, the connection lines of any two electric connection terminals 23 located on the same side of the symmetry line are arranged non-parallel to the symmetry line. That is, any two electric connection terminals 23 located on the same side of the symmetry line are asymmetric with respect to any one straight line perpendicular to the symmetry line, so that when the electric connection device 101 and the electric connector 102 are magnetically mated, the electric connection terminals 23 can be prevented from being reversely inserted, that is, the electric connection terminals 23 are prevented from not being inserted in the corresponding positions of the electric connector 102. In the present embodiment, four electrical connection terminals 23 are located on four apexes of one isosceles trapezoid, respectively.
Referring to fig. 1 to 3, alternatively, at least one pair of two magnetic members 22 are disposed with opposite magnetic pole directions. Specifically, at least one of the magnetic members 22 is disposed with a magnetic pole direction opposite to the magnetic pole direction of the other magnetic member 22. I.e. when the top cover 12 is overlooked from top to bottom, all magnetic members 22 have at least one south pole and one north pole oriented toward the top cover 12. It will be appreciated that the magnetic pole orientation of the electrical connector 102 is adapted to the magnetic pole orientation of the electrical connection device 101, i.e. the magnetic pole orientation of the electrical connector 102 is opposite to the magnetic pole orientation of the electrical connection device 101. Thus, not only the magnetic attraction of the electric connection device 101 and the electric connector 102 is prevented from being misplaced, but also the electric connection device 101 can be self-aligned when the magnetic member 22 of the electric connection device 101 and the magnetic member 22 of the electric connector 102 are magnetically attracted to the center, so that the electric connection terminal 23 can be quickly inserted into the accurate position of the electric connector 102.
Optionally, the magnetic pole directions of the two magnetic pieces 22 of any pair are opposite, that is, the magnetic pole directions of the two magnetic pieces 22 of the same pair are opposite, so as to improve the accuracy of the centering attraction between the electric connection device 101 and the electric connector 102.
Alternatively, the magnetic pole directions of the magnetic pieces 22 on the same side of the symmetry line are set to be the same, that is, the magnetic pieces 22 with south poles facing the top cover 12 are all on one side of the symmetry line, and the magnetic pieces 22 with north poles facing the top cover 12 are all on the other side of the symmetry line.
Optionally, a plugging hole is formed on the side surface of the base 11, which is communicated with the accommodating cavity 111 and is used for plugging the bus structure 30 with an external power supply.
