[0021] As shown in the drawings, two ends of the positive electrode conductive wire 3 are respectively connected to the anode terminal 12 of the first connector 1 and the anode terminal 22 of the second connector 2 and two ends of the negative electrode conductive wire 4 are respectively connected to the cathode terminal 13 of the first connector 1 and the cathode terminal 23 of the second connector 2.

The electrical mating section 21 of the second connector 2 and the positive and negative elect rode conductive wires 3, 4 in adjacency to the electrical mating section 21 are enclosed in an insulation seat body 24.

[0022] As shown in FIG. 2, the capacitor device 10 can be a capacitor or a supercapacitor. In this embodiment, the capacitor device 10 is a supercapacitor (or so-called electrical double-layer capacitor). The capacitor device 10 is disposed between the first and second connectors 1, 2 and securely arranged on the positive and negative electrode conductive wires 3, 4. The supercapacitor 5 has a first electrode 51 and a second electrode 52. The first electrode 51 is a positive electrode, while the second electrode 52 is a negative electrode. The first electrode 51 of the supercapacitor 5 is connected to the positive electrode conductive wire 3, while the second electrode 52 of the supercapacitor 5 is connected to the negative electrode conductive wire 4.

[0023] The supercapacitor 5 employs high-surface-area and high-porosity ruthenium or tantalum material as the electrodes. By means of the charge separation phenomenon caused by coulomb electrostatic force between the interfaces of the electrodes and the electrolyte, the supercapacitor 5 can achieve the object of power storage. Therefore, the supercapacitor 5 has the advantages of low equivalent series resistance, fast charging speed, high charging/discharging efficiency, extremely high capacitance, super-high large current discharging capability, high energy conversion efficiency, small energy loss, large current energy circulation efficiency 90%, high power density, long circulation life time, etc.

[0024] As shown in FIG. 1, in a preferred embodiment, a receiving box 6 is securely disposed on the positive and negative electrode conductive wires 3, 4. The supercapacitor 5 is disposed in the receiving box 6, whereby the receiving box 6 can provide protection effect for the supercapacitor 5. As shown in FIG. 2, in another preferred embodiment, the first electrode 51 of the capacitor device 10 is connected to or serially connected to at least one first resistor 91. Alternatively, the second electrode 52 of the capacitor device 10 is connected to or serially connected to at least one first resistor 91. The first resistor 91 serves to provide voltage division and voltage reduction effect for the supercapacitor 5.

[0025] FIG. 2 further shows that in another preferred embodiment, the supercapacitor 5 can be alternatively connected to a circuit protection module 9. For example, the circuit protection module 9 is connected to or serially connected to the positive electrode conductive wire 3 via the anode terminal 22 of the second connector 2. Alternatively, the circuit protection module 9 is connected to or serially connected to the negative electrode conductive wire 4 via the cathode terminal 23 of the second connector 2. Still alternatively, the circuit protection module 9 is connected to or serially connected to the first electrode 51 or the second electrode 52 of the supercapacitor 5. Moreover, the circuit protection module 9 can be serially connected to a second resistor 92, whereby the second resistor 92 is connected between the circuit protection module 9 and the first electrode 51 of the supercapacitor 5.

[0026] As shown in FIGS. 1 and 2, when using a first electrical apparatus 7 (such as a mobile power bank) to charge a second electrical apparatus 8 (such as an intelligent mobile phone), the electrical mating sections 11, 21 of the first and second connectors 1, 2 of the transmission cable of the present invention are respectively connected with the connector of the first electrical apparatus 7 and the connector of the second electrical apparatus 8. In this case, the circuit protection module 9 is connected between the capacitor device 10 (or the supercapacitor 5) and the second electrical apparatus 8. The first electrode 51 of the supercapacitor 5 is connected to the power supply positive electrode terminal 71 of the first electrical apparatus 7 via the first resistor 91, the positive electrode conductive wire 3 and the anode terminal 12. In addition, the first electrode 51 of the supercapacitor 5 is connected to the positive electrode terminal 811 of the battery 81 of the second electrical apparatus 8 via the first resistor 91, the positive electrode conductive wire 3, the anode terminal 12, the second resistor 92 and the circuit protection module 9. Also, the second electrode 52 of the supercapacitor 5 is respectively connected to the power supply negative electrode terminal 72 of the first electrical apparatus 7 and the negative electrode terminal 812 of the battery 81 of the second electrical apparatus 8 via two ends of the negative electrode conductive wire 4. At this time, the supercapacitor 5, the battery 81 of the second electrical apparatus 8 and the circuit protection module 9 form a parallel circuit. Accordingly, the supercapacitor 5 is charged by the power supply of the first electrical apparatus 7 to charge the battery 81 of the second electrical apparatus 8. By means of the fast charging/discharging property of the supercapacitor 5, the instantaneous surges possibly generated when charged by the first electrical apparatus 7 can be absorbed to prevent the circuit and the battery 81 of the second electrical apparatus 8 or the circuit protection module 9 from being affected by the instantaneous surges. Also, a filtering function is provided to supply more stable power for the second electrical apparatus 8. Even if the transmission cable and the supercapacitor 5 of the present invention are damaged by the surges, the second electrical apparatus 8 can be still secured from the affection of the surges.

[0027] When using the first electrical apparatus 7 (such as a computer) to transmit data to the second electrical apparatus 8 (such as an intelligent mobile phone), the supercapacitor 5 and the data access circuit of the second electrical apparatus 8 also form a parallel circuit. In this case, the first electrical apparatus 7 can transmit data to the second electrical apparatus 8 via the positive and negative electrode conductive wires 3, 4 and the supercapacitor 5. Accordingly, by means of the properties of fast charging/discharging speed, high energy conversion efficiency, extremely high capacitance, etc. of the supercapacitor 5, the data transmission speed can be effectively enhanced.

[0028] In a real test of 3G data transmission, the conventional transmission cable without parallel capacitor has a data downloading speed of 19.84 Mbps and a data uploading speed of 3.5 Mbps within a 30 ms time range. The transmission cable with the supercapacitor 5 of the present invention has a data downloading speed of 44.38 Mbps and a data uploading speed of 3.62 Mbps within a 36 ms time range. Therefore, the data transmission speed of the present invention is about 75% increased.

[0029] In a real test of 4G data transmission, the conventional transmission cable without parallel capacitor has a data downloading speed of 29.23 Mbps and a data uploading speed of 1.15 Mbps within a 49 ms time range. The transmission cable with the supercapacitor 5 of the present invention has a data downloading speed of 32.46 Mbps and a data uploading speed of 6.48 Mbps within a alms time range. Therefore, the data transmission speed of the present invention is about 85% increased.

[0030] Please now refer to FIG. 3. In a modified embodiment, the above circuit protection module 9 and the second resistor 92 can be alternatively disposed on the positive electrode conductive wire 3 or the negative electrode conductive wire 4 of the transmission cable of the present invention. In this case, the circuit protection module 9 is serially connected to the positive electrode conductive wire 3 or the negative electrode conductive wire 4 or the circuit protection module 9 is serially connected to the first electrode 51 or the second electrode 52 of the supercapacitor 5, while the second resistor 92 is connected between the first electrode 51 of the supercapacitor 5 and the circuit protection module 9. Accordingly, the capacitor device 10 and the circuit protection module 9 provide multilevel protection effects for the circuit of the second electrical apparatus 8.

[0031] It should be noted that by means of the circuit design of the supercapacitor 5 (or the capacitor) connected to the transmission cable in parallel, the present invention is able to provide surge absorption and filtering effects for an existent electrical apparatus without circuit protection module. Also, the present invention apparently increases the data transmission speed and is able to provide a low-cost circuit protection structure for an electrical apparatus already having circuit protection module so as to prolong lifetime of the electrical apparatus and shorten the data access time.

[0032] The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
