An electronic device comprising a body, a cover, a rotatably connecting body and a pivoting mechanism of the body, electrically connecting the body and the electronic device in the cover body; the fl-rotating mechanism comprises a pivot frame and a towing member pivotally connected to the pivoting frame, the communication unit comprising a first signal line and a second signal line, wherein the first line includes a circular first line and a second row connected to the first line Line, ° The first-row line surrounds the rotating piece, and the second line is electrically connected to the electronic device in the body of the 201001445 body at one end away from the first line; the line and the fourth row connected to the third line:: = circle_the third row is electrically connected to the first row, and the fourth row is connected to the electronic device of the inner row of the wire cover, and the second signal line is connected to the end of the second signal line. The first core § the cover rotates relative to the body rotation line. The second cable can be opposite to the first-type communication unit of the first signal line, and the electronic device is borrowed, and the body is provided with a body and a cover body: _ structure: two signal lines including a circle The first line of the arc is connected to the first line, the first line surrounds the pivoting member, and the first row of the first _, ,, and the electronic device in the body are electrically connected to the electronic device ί7 second = line-end two "Green" running knot - Xia brother a t-line including the arc-shaped first ~,,, ^ brother, the second row of the second line, the third line of the first row of the line and the first - line electrical Connection, fourth ς = electronic connection of the electronic device in the body, and when the third line of the first -^ = signal line of the cover can be relative to the (four) of the first signal line, the electronic device and the communication unit, when the electronic device When the cover body rotates relative to the body, the third line of the second signal line can be rotated relative to the first line of the first signal line. The second signal line does not bend, so that the first ## line can be broken. The chance. [Embodiment] Referring to FIG. 2 and FIG. 2 simultaneously, the electronic device 99 includes a body 2〇, a 201001445 cover 30, a pivot mechanism 40 rotatably connecting the body 20 and the cover 30, and an electrical connection body 20 and a cover. The communication unit 60 of the electronic device within the body 30. The body 20 A is a square body having two positioning members (not shown). The cover body 3 is substantially a square body having two coaxially disposed hollow sleeve-like shaft covers 32 disposed on one side of the body 20. The pivoting mechanism 40 includes two pivoting brackets 42 and a pivoting member 44 pivotally connected between the two pivoting brackets 42. The two pivoting brackets 42 are fixed to one of the body and the cover body, and the pivoting member 44 is fixed to the other of the body 20 and the cover body 3. In this embodiment, the pivoting member 44 is fixed to the cover body 3 and the two pivoting frames 42 are fixed to the body 2〇 as an example. The two pivoting brackets 42 are fixed to the main body 2 通过 by a conventional fixing method. In the embodiment, the two pivoting brackets 42 respectively include a fixing portion 422 and a pivoting portion 424 connected to the fixing portion 422 . The fixing portion 422 is fixed to the two positioning members of the body 20. The two pivoting portions 424 are all cylindrical, and the opposite sides of the two are provided with cylindrical receiving grooves (not shown). The two ends of the pivoting member 44 are respectively inserted into the receiving slots of the two pivoting portions 424, and the two ends of the pivoting member 44 are respectively inserted into the receiving slots of the two pivoting portions 424. The communication unit 60 includes a first signal line 62 and a second signal line 64. The first signal line 62 is electrically coupled to the electronics within the body 20 and includes a circular first line 622 and a linear second row 624 coupled to the first line 622. The first row of wires 622 surrounds the surface of the pivoting member, and the end of the second row of wires 624 away from the first row of wires 622 is electrically connected to the electronic device in the body 2〇. The second signal line 64 includes a circular arc-shaped third row line 642 and a linear fourth row line 644 connected to the third row line 642. The third row of wire 2 surrounds the first row line 622 and the first row line 622. Electrical connection. The fourth row 644 away from the second line 642 is electrically connected to the electronics in the cover 30. When the cover body 3 rotates relative to the body 20, the third row line 642 of the second signal line 64 can rotate relative to the first row and line 622 of the first ## line 62, and the second signal line 64 does not bend. Thereby, the probability of the second signal line can be reduced. λ In addition, the pivoting member 44 is surface insulated to block the flow of the communication unit 6〇 to it. The pivoting member 44 includes a rotating shaft 442 and a hollow sleeve-shaped insulating member 444 that is disposed on the rotating shaft 4. The insulating member 444 is made of an insulating material, which may be a separate device or integrated with other components. When the insulating member 444 is a separate device, the rotating shaft (4) can smash the mechanical strength of the metal material. When the rotating shaft 442 itself is insulated, the insulating member 444 can be directly formed on the rotating shaft 442, and the flow is installed. In this embodiment, the insulating member 444 is directly formed on the rotating shaft
