[ detailed description ] of the utility model

The utility model is further described below with reference to the drawings and examples.

Referring to fig. 1, the present utility model provides a charging data line 100, which includes an FPC cable 50, a first connector 61 and a second connector 62. The first connector 61 and the second connector 62 are connected to both ends of the FPC cable 50, respectively.

Wherein,

referring to fig. 1 and 2, the FPC cable 50 includes an FPC signal wire 1, a first insulating layer 3, and an overcoat 5. The first insulating layer 3 covers the FPC signal line 1, and the outer cover 5 covers the first insulating layer 3. Specifically, the FPC signal line 1 is embedded in the first insulating layer 3 to form a one-piece whole.

In this embodiment, the FPC signal line 1 is a data signal transmission layer. Specifically, the FPC signal line 1 is a sheet-like metal foil conductor. Such as copper foil, constantan alloy foil, or gold foil, etc. Thus, the FPC cable 50 having flexibility, ultra-thin property, and light weight is formed.

Referring to fig. 2 and 3, in the present embodiment, the data signal transmission layer is a double layer, namely a first layer conductor 1A and a second layer conductor 1B. It will be appreciated that the first layer conductor 1A and the second layer conductor 1B may each be a metal foil of a different material. For example, the first layer conductor 1A is a copper foil sheet, and the second layer conductor 1B is a constantan alloy foil. In this way, the FPC cable 50 has more optimal usability on the basis of ultra-thinness and lightweight.

The FPC signal line 1 is only a carrier (medium) for data signal transmission, and the FPC signal line 1 may be a single-layer metal foil conductor in order to save cost on the basis of meeting the data transmission requirement. Of course, the FPC signal line 1 may also be a multi-layered metal foil conductor to meet the data transmission requirements.

Preferably, in the present embodiment, the FPC cable 50 is provided with the power supply line 10 to separate the conductive transmission function from the data transmission function; thereby being capable of more flexibly meeting charging equipment with different current demands. The power supply line 10 is insulated from the FPC signal line 1.

In this embodiment, the power lines 10 are two large current power lines; a first large current line 10A and a second large current line 10B, respectively. As such, the electrical conduction requirements of audio devices, playback devices, or multimedia devices (e.g., speakers, HDMI sound or VGA audio video devices, displays, computers, etc.) with high current requirements are met. Specifically, the current of the power line 10 is 3A-5A.

Preferably, to meet the connection requirement of an audio device, a playback device, or a multimedia device having a large current demand, the first connector 61 may be a USB a male plug, a type C male plug, or a Micro USB interface. The second connector 62 may be a type C male plug, a lighting interface, an audio line interface, a Micro USB interface, a speaker line plug, an HDMI (high definition multimedia interface), or a VGA interface.

Further, referring to fig. 2, 3 and 4, in the present embodiment, the power line 10 has a single-core and single-layer insulation structure. Specifically, the power supply line 10 includes a conductive core 11 and a second insulating layer 13; the conductive core 11 is covered with a second insulating layer 13. The second insulating layer 13 is adjacent to or in contact with the first insulating layer 3, thus realizing one-piece integral mutual insulation of the power supply line 10, the FPC signal line 1, and the first insulating layer 3.

The first insulating layer 3 is a PI (polyimide) film; the second insulating layer 13 and the outer envelope 5 are both PVC (polyvinyl chloride) films. It can be appreciated that the smaller the coating thicknesses of the first insulating layer 3, the second insulating layer 13, and the overcoat 5, the thinner the FPC cable 50 and the charging data line 100 can be.

Specifically, referring to fig. 1, the first connector 61 and the second connector 62 each have a power pin 600 and a data pin 650. The power line 10 is connected to the power pin 600, and the fpc signal line 1 is connected to the data pin 650.

More specifically, referring to fig. 1 to 4, the power pin 600 includes a power positive electrode and a power negative electrode. The power anodes of the first connector 61 and the second connector 62 are respectively power anodes 601A and 601B, and the power cathodes of the first connector 61 and the second connector 62 are respectively power cathodes 602A and 602B; the positive power supply electrode 601A of the first connector 61 and the negative power supply electrode 602B of the second connector 62, and the negative power supply electrode 601B of the first connector 61 and the positive power supply electrode 602A of the second connector 62 are respectively connected to the same power supply line 10. In the present embodiment, the conductive cores 11 at both ends of the first large current wire 10A of the two large current power wires are connected to the power source positive electrode 601A of the first connector 61 and the power source negative electrode 602B of the second connector 62, respectively; the conductive cores 11 at both ends of the second current line 10B are connected to the power negative electrode 602A of the first connector 61 and the power positive electrode 601B of the second connector 62, respectively. Thus, the current transmission function is realized.

It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
