In the above electronic device and communication unit, when the cover of the electronic device rotates relative to the body, the third line of the second signal line can rotate relative to the first line of the first signal line, and the first signal line does not bend. Thereby, the probability that the second signal line is broken can be reduced. [Embodiment] Referring to FIG. 1 and FIG. 2 simultaneously, the electronic device 99 includes a body 20, 1376, 703, a cover 30, a pivot mechanism 40 that rotatably connects the body 20 and the cover 30, and an electric steep connection body 20. The communication unit 6 and the body 20 of the electronic device in the cover 30 are substantially square and have two positioning members (not shown). The cover body 30 is substantially a square body, and two coaxially disposed hollow sleeve-like shaft covers 32 are disposed on one side of the body 2〇. The pivoting mechanism 40 includes two pivoting brackets 42 and a towing member 44 pivotally connected between the two pivoting brackets 42. The two pivoting jaws 42 are fixed to one of the body 2 and the cover body, and the pivoting member is fixed to the other of the body 2 and the cover buckle. In this embodiment, the pivoting member 44 is fixed to the cover body and the two pivoting frames 42 are fixed to the body 2〇 as an example. The two pivoting brackets 42 can be fixed to the main body by a conventional fixing method. In the present embodiment, the two pivoting brackets 42 respectively include a fixing portion and a pivoting portion 424 connected to the fixing portion 422. The fixing portion 422 is fixed to the two pieces of the spring body 20. The two pivoting portions 424 are all cylindrical, and the opposite sides are provided with a cylindrical receiving groove (not shown). The two ends of the pivoting member 44 are respectively inserted through the two shaft covers. The rear ends are respectively inserted into the receiving slots of the two pivoting portions 424, thereby pivoting the cover 30 to the body 20. The mountain communication sheet T0 6G includes The first signal line 62 and the second signal line 64. The first and the line 62 are electrically connected to the electronic device in the body 20, and the curved first row line 622 is connected to the first/, ^ 轶 in the first row. The linear second ridge 624 of the line 622. The first row 622 11 surrounds the surface of the towing member 44, and the second row of wires is away from the end of the first row 622 and the body (4) electronic device (4) 1376703. The two signal lines 64 include a circular arc-shaped third row 纟 (4) and a linear fourth-line state connected to the third 642. The third line (4) surrounds the first row 622 and is electrically connected to the first row 622. The fourth row 644 is electrically connected to the electronic device in the cover 3 () away from the end of the second wire 642. When the cover 30 is rotated relative to the body 20, the third line (4) of the signal (4) can be relatively The first row line 622 of the first signal line 62 rotates, and the second signal line 64 does not bend, so that the probability of the second signal line (4) being broken can be reduced.
