The first contact set 2 may also connect to the wire or printed circuit board as needed.
The exterior casing 3 is made of but not limited to the insulating material (e.g. plastics). The exterior casing 3 has a third end 31 and an opposite fourth end 32. A containing space 33 is formed inside the exterior casing 3 and between the third end 31 and the fourth end 32. An opening 34 is formed in the third end 31, and the containing space 33 connects to the opening 34. A second slope 35 is formed in the interior of the containing space 33, and the second slope 35 is with but not limited to a plate-like slope, or cone-like slope. In this embodiment, the containing space 33 is a cone-like hole, and the second slope 35 is with corresponding cone-like slope and formed in the interior of the containing space 33 with a cone-like hole, the outside diameter of the containing space 33 is decreasing from the third end 31 towards the fourth end 32.

The second contact set 4 has a plurality of wire and contact points (not shown), in other words, the second contact set 4 includes a plurality of second contact points 41 made of conductive electrical metal or alloy. The quantities and arrangement of the second contact points 41 are not limited and could be modified as required. The second contact points 41 expose to the interior of the second contact set 4, so the conducting element 5 is electrically connected to the first contact point 21 of the first contact set 2. The second contact set 4 may also connect to the wire or printed circuit board as needed.
The conducting element 5 is a two way conductive unit and provided between the first slope 14, the first contact set 2, second slope 35 and the second contact set 4. The conducting element 5 is used to conduct the first contact set 2 and the second contact set 4. The conducting element 5 includes an insulating main body 51 and a plurality of connecting terminals 52 (as shown in FIG. 6, 7). The insulating main body 51 is made of, but not limited to, insulating material (e.g. plastics). In this embodiment, the insulating main body 51 is formed in a hollow cone, and the inclination of the insulating main body 51 is corresponding to the inclination of the first slope 14 and the second slope 35.
The insulating main body 51 is molding in one or assembled by a plurality of small plates. In this embodiment, the insulating main body 51 is assembled by a plurality of plates 511 with a curved shape, and fasteners 512 are utilized to bond the plates 511 to each other, so the insulating main body 51 is with a hollow cone-like shape. The outer diameter and the length of the insulating main body 51 could be increasing or extending according to the need of quantity of the contact points.
The connecting terminals 52 are provided on the insulating main body 51, the connecting terminals 52 are made of conductive electrical metal or alloy. The shape, quantities, and the arrangement of the connecting terminals 52 are not limited and could be modified as required. The connecting terminals 52 are exposed to the interior and exterior of the insulating main body 51 and correspond to the first contact points 21 and the second contact points 41, so the conducting element 5 electrically contacts the first contact set 2 and the second contact set 4.

The conducting element 5 contacts the first contact set 2 and the second contact set 4 by the manner of rotating or compression. Namely, when the plug portion 13 inserts into the containing space 33, the interior casing 1, the first contact set 2, exterior casing 3, second contact set 4, and the conducting element 5 contact to each other by manner of rotating, so the first contact portions 521 of the connecting terminal 52 contact the first contact points 21, and the second contact portion 522 of the connecting terminal 52 contact the second contact point 41, so the first contact points 21 contact the second contact points 41 by the connecting terminal 52. The interior casing 1, the first contact set 2, exterior casing 3, second contact set 4, and the conducting element 5 moves axially and contact to each other by manner of compression, so the first contact portions 521 of the connecting terminal 52 contact the first contact points 21, and the second contact portion 522 of the connecting terminal 52 contact the second contact point 41, so the first contact points 21 contact the second contact points 41 by the connecting terminal 52.
The connecting terminal 52 rubs the first contact point 21 and the second contact point 41 and so removes the oxide of the first contact point 21 and the second contact point 41 by the abovementioned rotating or compression process of the conducting element 5, and the connecting terminal 52 closely contacts the first contact point 21 and the second contact point 41.
The conducting element 5 contacts the first contact point 21 and the second contact point 41 by the manner of “one to one”, “one to many”, or “many to many”. The conducting element 5 has a wire arrangement corresponding to the connecting terminals 52 of the conducting element 5 to meet the abovementioned use type.
