The USB data line is a cable for charging and data transmission of electronic equipment, and four shunts are arranged in the USB data line, and comprise two power shunts and two data shunts which are respectively used for transmitting electric energy and transmitting data.
The fast charging function of the current mobile phone requires a data line to bear large current to meet the requirement of fast charging, and in order to ensure the charging safety, a thicker power shunt circuit is required to be arranged in the data line; and this not only consumed more materials, also made the data line become thick and heavy simultaneously, reduced the portability.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide a portable fast charging data line capable of safely carrying a large current while saving materials and keeping light weight.
The first technical scheme adopted by the invention for solving the technical problems is as follows: the portable quick charging data line comprises a mobile phone connector and a USB connector which are electrically connected by a connecting wire, wherein two current contact pins and two data contact pins are respectively arranged in the mobile phone connector and the USB connector; the connecting wire comprises two current wires and two data wires; each current lead is respectively connected with an electromagnet in series inside the mobile phone connector and the USB connector and then connected with the current contact pin, the surface of an excitation lead of the electromagnet is exposed, and the wire diameter is not less than 1.5 times of that of the current lead; each data wire is respectively connected with a moving contact end of a single-pole double-throw switch in the mobile phone connector and the USB connector, and the moving contact of the moving contact end can hit an excitation wire exposed on the surface of the electromagnet and is electrically connected with a contact end of the data contact pin; and the moving contact is made of iron, when the charging current in the excitation wire is smaller than a design threshold value, the moving contact is electrically connected with a contact end of the data contact pin, and when the charging current in the excitation wire reaches the design threshold value, the moving contact is attracted by the electromagnet and is electrically connected with the excitation wire, so that two parallel circuits are formed in the connecting wire, and each parallel circuit comprises a current wire and a data wire.
Preferably, the moving contact of the moving contact end of the single-pole double-throw switch is made of soft iron, the contact end of the data contact pin is made of a permanent magnet, and when the exciting current of the electromagnet does not reach the design threshold value, the contact end adsorbs the moving contact through magnetism; and when the exciting current of the electromagnet reaches the design threshold, the magnetic attraction of the electromagnet overcomes the magnetic attraction of the contact end to attract the moving contact to the electromagnet.
Preferably, the moving contact at the moving contact end of the single-pole double-throw switch is made of soft iron and has elasticity, when the charging current in the excitation wire is smaller than a design threshold value, the moving contact is in contact with the contact end of the data contact pin, and when the excitation current of the electromagnet reaches the design threshold value, the magnetic attraction force of the electromagnet overcomes the elasticity to attract the electromagnet.
The first technical method has the advantages that: in a non-quick charging mode, due to the fact that charging current is low, a data wire in a connecting wire is connected with data contact pins in a mobile phone connector and a USB connector through a single-pole double-throw switch, and therefore data transmission and low-current charging can be conducted on the quick charging data wire at the same time; when the charging current reaches a designed threshold value, namely in a quick charging mode, a data wire in a connecting wire is connected with current contact pins in a mobile phone connector and a USB connector through a single-pole double-throw switch, so that the data wire is connected with the current wire in parallel, a current channel is thickened, and a large-current charging state is achieved; therefore, the quick charging data line can ensure the safety of heavy current charging under the condition that the wire is not integrally thickened, not only saves materials, but also keeps the lightness and portability of the data line.
The second technical scheme adopted by the invention for solving the technical problems is as follows: the portable quick charging data line comprises a mobile phone connector and a USB connector which are electrically connected by a connecting wire, wherein two current contact pins and two data contact pins are respectively arranged in the mobile phone connector and the USB connector; the connecting wire comprises two current wires and two data wires; each current lead is respectively connected with a bimetallic strip in series inside the mobile phone connector and the USB connector and then connected with the current contact pin, and each data lead is respectively connected with a fixed metal strip in series inside the mobile phone connector and the USB connector and then connected with the data contact pin; after the current value of the bimetallic strip flowing through the bimetallic strip exceeds a design threshold value, the bimetallic strip bends and deforms towards the fixed metal strip side and props against the fixed metal strip, so that two parallel paths are formed in the connecting line, and each parallel path comprises a current conducting wire and a data conducting wire.
The second technical method has the advantages that: in a non-quick charging mode, due to the fact that charging current is small, deformation of a bimetallic strip in a connecting wire is small, and the bimetallic strip is independent of a fixed metal strip, so that a current lead and a data lead are independent of each other; when the charging current exceeds a design threshold value, namely in a quick charging mode, the bimetallic strip in the current lead is greatly deformed and props against the fixed metal strip in the data lead, so that the data lead is borrowed by the current lead, and at the moment, the current channel is thickened, so that the current enters a large-current charging state; similarly, the quick charging data line can ensure the safety of heavy current charging under the condition of not thickening the wire integrally, not only saves materials, but also keeps the lightness and portability of the data line.

In the first embodiment, the moving contact 51 at the moving contact end of the single-pole double-throw switch 5 is made of soft iron, and the contact end of the data contact pin 22 is made of a permanent magnet, and when the exciting current of the electromagnet 4 does not reach the design threshold, as shown in fig. 1, the contact end magnetically attracts the moving contact 51; when the exciting current of the electromagnet 4 reaches the design threshold, as shown in fig. 2, the magnetic attraction of the electromagnet 4 overcomes the magnetic attraction of the contact end to attract the movable contact 51 to the electromagnet 4.
In the slow charging mode, due to the fact that the charging current is low, the data wire 12 in the connecting wire is connected with the data contact pin 22 in the mobile phone connector 2 and the USB connector 3 through the single-pole double-throw switch 5, and therefore data transmission and low-current charging can be conducted on the fast charging data wire at the same time; when the charging current reaches a designed threshold value, namely in a fast charging mode, the data wire 12 in the connecting wire 1 is connected with the current contact pin 21 in the mobile phone connector 2 and the USB connector 3 through the single-pole double-throw switch 5, so that the data wire 12 is connected with the current wire 11 in parallel, a current channel is thickened, and a large-current charging state is achieved; therefore, the quick charging data line can ensure the safety of heavy current charging under the condition that the wire is not integrally thickened, not only saves materials, but also keeps the lightness and portability of the data line.
Example two:
in the second embodiment shown in fig. 3 and 4, the portable fast charging data line includes a mobile phone connector 2 and a USB connector 3 electrically connected by a connection line 1, wherein two current contact pins 21 and two data contact pins 22 are respectively disposed in the mobile phone connector 2 and the USB connector 3; the connecting wire 1 comprises two current wires 11 and two data wires 12; each current lead 11 is respectively connected with a bimetallic strip 6 in series inside the mobile phone connector 2 and the USB connector 3 and then connected with the current contact pin 21, and each data lead 12 is respectively connected with a fixed metal sheet 7 in series inside the mobile phone connector 2 and the USB connector 3 and then connected with the data contact pin 22; after the current value of the bimetallic strip 6 flowing through the bimetallic strip exceeds a design threshold value, the bimetallic strip is bent and deformed towards the fixed metal strip 7 and props against the fixed metal strip 6, so that two parallel paths are formed in the connecting wire 1, and each parallel path comprises a current lead 11 and a data lead 12.
In the slow charging mode of the portable fast charging data line in the second embodiment, since the charging current is small, the deformation of the bimetal strip 6 in the connection line 1 is small, and at this time, as shown in fig. 3, the portable fast charging data line is independent from the fixed metal strip 7, so that the current lead 11 and the data lead 12 are independent from each other; when the charging current exceeds the design threshold, that is, in the fast charging mode, as shown in fig. 4, the bimetal 6 in the current lead deforms greatly and abuts against the fixed metal sheet 7 in the data lead 12, so that the data lead 12 is borrowed by the current lead 11, and the current channel is thickened at this time, thereby entering a large-current charging state; similarly, the quick charging data line can ensure the safety of heavy current charging under the condition of not thickening the wire integrally, not only saves materials, but also keeps the lightness and portability of the data line.
