Main element symbol description

The following detailed description will be further explained with reference to the above drawings the utility model.

Specific embodiment

Referring to Fig. 1, it illustrates data line 1 provided by the preferred embodiment of the utility model.The data line 1 wraps It includes, but is not limited only to, first interface 10, second interface 20 and charging conductor 30.Wherein, the first interface 10 and second interface 20 are individually fixed in the both ends of the charging conductor 30.The first interface 10 and second interface 20 are used for and electronic equipment (figure Do not show) it is electrically connected, and charging is carried out to the electronic equipment or is carried out data transmission with the electronic equipment.In this embodiment party In formula, the electronic equipment is smart phone or tablet computer.

In the present embodiment, the charging conductor 30 has a diameter larger than according to that can be made by the standard of 3A electric current The diameter of existing common charging cable, internal resistance are less than the internal resistance of existing common charging cable, so that the data line 1 supports 5V/3A's Charging output.

Preferably, in the present embodiment, the first interface 10 is Type-C interface, and the second interface 20 is lightning (Lighting) interface.In other embodiments, the first interface 10 or Type-A interface.

Referring to Fig. 2, the second interface 20 includes two group of first signaling interface pin S_A, the positive pin DATA+ of data line, The negative pin DATA- of data line, power supply signal pin V_usb, second signal interface pin S_B, the first undefined pin NC1, second not Define pin NC2 and grounding pin GND.Wherein, the charging conductor 30 connects the power supply signal pin V_usbWith the ground connection Pin GND.

In the present embodiment, the first interface 10 includes two group of first grounding pin G1, receives positive signal pin R_x +, receive negative signal pin R_x, the first power supply signal pin VBUS1, Function Extension signal pins RFU, the negative pin D- of data line, The positive pin D+ of data line, voltage detection signal pin CC1, second source signal pins VBUS2, positive signal pin T is sent_X+, hair Send negative signal T_XPin and the second grounding pin G2.Wherein, two groups of pin arrangements are contrary, so that the first interface 10 It positive and negative can be inserted into, directionless requirement.

In the present embodiment, protection circuit 100 is provided in the first interface 10, for the first interface 10 Carry out voltage-stabilizing protection.Since Type-C interface supports QC (Quick Charge, fast charge) high pressure agreement, the first interface 10 exists When being electrically connected with the adapter for connecting power supply, charging voltage can be in high pressure conditions moment.However, since lightning interface does not prop up High pressure fast charge is held, excessively high charging voltage is easy to cause the second interface 20 to damage.Therefore, the data line 1 is described The protection circuit 100 is set in one interface 10 and carries out voltage-stabilizing protection.In other embodiments, the protection circuit 100 It can be set in the second interface 20.
