BACKGROUND 
     1. Technical Field 
     The present disclosure relates to electrical connectors. 
     2. Description of Related Art 
     Electrical connectors are used to electrically connect two electronic devices, and enable the two electronic devices to exchange signals with each other. The electrical connector uses metal pins, but the metal pins are small and delicate and not amenable to high numbers of connection/disconnection cycles. 
     Therefore, there is room for improvement within the art.

     DETAILED DESCRIPTION 
       FIGS. 1-3  show an electronic connector  100  having a first connector  10 , and a second connector  20  detachably sleeved on the first connector  10 . The first connector  10  electrically connects with a first electronic device (not shown), and the second connector  20  electrically connects with a second electronic device (not shown). Thus, the first electronic device is electrically connected to the second electronic device when the first connector  10  is coupled to the second connector  20 . 
     The first connector  10  is insulated externally. One end of the first connector  10  is a hollow cylinder. The other end of the first connector  10  has a first magnetic body  11 , a first conductive body  12 , a second conductive body  13 , a third conductive body  14 , and a second magnetic body  15 . The first magnetic body  11 , the first conductive body  12 , the second conductive body  13 , the third conductive body  14  are all annular. The second magnetic body  15  is columnar. The second magnetic body  15  is positioned at the center of the first connector  10 . The first magnetic body  11  surrounds the second magnetic body  15 . The first, the second, and the third conductive bodies  12 ,  13 , and  14  are positioned in that order between the first magnetic body  11  and the second magnetic body  15 . The first magnetic body  11 , the first conductive body  12 , the second conductive body  13 , the third conductive body  14 , and the second magnetic body  15  are concentrically arranged. 
     A single cross section of the first magnetic body  11 , the first conductive body  12 , the second conductive body  13 , the third conductive body  14 , and the second magnetic body  15  forms a protruding and a first inserting surface  16 . A single cross section of the first conductive body  12 , the second conductive body  13 , the third conductive body  14 , and the second magnetic body  15  forms annular steps inward and down. The cross sections of the second magnetic body  15  and of the first magnetic body  11  are coplanar. There are non-conductive concentric first gaps  17  between every adjacent two of the first, the second, and the third conductive bodies  12 ,  13 , and  14  radially around the central axis of the first connector  10 . Thus, the first, the second, and the third conductive bodies  12 ,  13 , and  14  cannot connect electrically. 
     The external surface of the second connector  20  is electrically insulated. One end of the second connector  20  is a hollow cylinder. The other end of the first connector  10  has a third magnetic body  21 , a fourth conductive body  22 , a fifth conductive body  23 , a sixth conductive body  24 , and a fourth magnetic body  25 . 
     The fourth magnetic body  25  is columnar and positioned at the center of the second connector  20 . The third magnetic body  21  surrounds the fourth magnetic body  25 . The fourth conductive body  22 , the fifth conductive body  23 , and the sixth conductive body  24  are positioned in that order between the third magnetic body  21  and fourth magnetic body  25 . The third magnetic body  21 , the fourth conductive body  22 , the fifth conductive body  23 , the sixth conductive body  24 , and the fourth magnetic body  25  are all annular and concentrically arranged. The annular diameters of the third magnetic body  21 , the fourth conductive body  22 , the fifth conductive body  23 , the sixth conductive body  24 , and the fourth magnetic body  25  match those of the first magnetic body  11 , the first conductive body  12 , the second conductive body  13 , the third conductive body  14 , and the second magnetic body  15  respectively. A single cross section of the fourth magnetic body  25 , the sixth conductive body  24 , the fifth conductive body  23 , the fourth conductive body  22 , and the third magnetic body  21  forms a second inserting surface  26 . A single cross section of the fourth magnetic body  25 , the sixth conductive body  24 , the fifth conductive body  23 , the fourth conductive body  22  forms annular steps outward and up, and substantially matches and accommodates the cross-sectional profile of the first conductive body  12 , the second conductive body  13 , the third conductive body  14 , and the second magnetic body  15 . The cross sections of the third magnetic body  21  and of the fourth magnetic body  25  are coplanar. There are second gaps  27  (see  FIG. 4 ) between every adjacent two of the fourth magnetic body  25 , the sixth conductive body  24 , the fifth conductive body  23 , which provide the same function as the first gaps  17  (see  FIG. 4 ) but in relation to the fourth conductive body  22 , the fifth conductive body  23 , and the sixth conductive body  24 . The annular face of the third magnetic body  21  meets the annular face of the first magnetic body  11 . The magneticic pole of the first magnetic body  11  on the first inserting surface  16  is opposite to the magneticic pole of the third magnetic body  21  on the second inserting surface  26 . The circular face of the fourth magnetic body  25  meets the circular face of the second magnetic body  15 . The magneticic pole of the second magnetic body  15  on the first inserting surface  16  is the same with that of the first magneticic pole of the first magnetic body  11  on the first inserting surface  16 , and opposite to that of the fourth magnetic body  25  on the second inserting surface  26 . 
     Referring to  FIG. 4 , the manner of operation of the electrical connector  100  is described. For example, the first inserting surface  16  is coupled to the second inserting surface  26 , so the first magnetic body  11 , the first conductive body  12 , the second conductive body  13 , the third conductive body  14 , and the second magnetic body  15  make respective contact with the third magnetic body  21 , the fourth conductive body  22 , the fifth conductive body  23 , the sixth conductive body  24 , and the fourth magnetic body  25 . Thus, the first magnetic body  11  and the second magnetic body  15  respectively contact the third magnetic body  21  and the fourth magnetic body  25  to form a sealed room enclosing the six conductive bodies  12 ,  13 ,  14 ,  22 ,  23 , and  24 . The first, the second, and the third conductive bodies  12 ,  13 , and  14  contact the fourth, fifth, and sixth conductive bodies  22 ,  23 , and  24  when the first magnetic body  11  and the second magnetic body  15  are in respective contact with the third magnetic body  21  and the fourth magnetic body  25 . The first connector  10  and the second connector  20  in this manner make an electrical connection with each other. 
     As described above, the cross section of the first magnetic body  11  is lower than that of the first, the second, and the third conductive bodies  12 ,  13 , and  14 . The cross section of third magnetic body  21  is higher than that of the fourth, the fifth, and the sixth conductive bodies  22 ,  23 , and  24 . Thus, the first connector  10  and the second connector  20  make firm and unequivocal contact, enhanced and strengthened by the mating structure of the two connectors of the electrical connector  100 . The first and the second connectors  10  and  20  both include but are not limited to three conductive bodies. 
     The first magnetic body  11  and the second magnetic body  21  form a sealed enclosure, thus the ingress of dust and water is prevented, and the service life of the electrical connector  100  will be longer. Further, the first connector  10  and the second connector  20  using ring-shaped conductive bodies renders each one more difficult to damage. Moreover, the ring shaped conductive bodies will self-connect even if the two connectors are presented at an oblique angle, thus it is very convenient. 
     Even though relevant information and the advantages of the present embodiments have been set forth in the foregoing description, together with details of the functions of the present embodiments, the disclosure is illustrative only; and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
