The technical scheme adopted by the invention for solving the technical problems is as follows: the anti-abrasion data line comprises a USB joint and a mobile phone joint, wherein the USB joint and the mobile phone joint respectively comprise two data contacts and two power contacts inside, and the data contacts and the power contacts in the USB joint and the mobile phone joint are in one-to-one correspondence; the USB connector and the mobile phone connector are internally provided with two pairs of data contacts which correspond to each other and are electrically connected through a spring respectively, and the two springs are coaxially arranged, so that the spring wires of the two springs are abutted against each other and extend spirally in parallel; two power contacts in the USB joint are electrically connected to a wireless electric energy transmitting module in the USB joint, and two power contacts in the mobile phone joint are electrically connected to a wireless electric energy receiving module in the mobile phone joint; and the antennas of the wireless power transmitting module and the wireless power receiving module are arranged in the surrounding area of the spring.

Preferably, the surface of the spring is wrapped with an insulating layer, such as insulating paint.

Preferably, a soft shielding tube with a metal coating on the surface is further arranged on the inner side of the spring, and the shielding tube surrounds the antennas of the wireless power transmitting module and the wireless power receiving module. Further, the shielding pipe is made of tinfoil with a plastic film covered on the surface.

Preferably, the spring is made of iron wires, an electromagnet with an insulated surface is arranged at the end part, facing the spring, of the mobile phone connector, the output end of the wireless power receiving module is divided into two paths, one path is electrically connected with a power supply contact in the mobile phone connector, and the other path is electrically connected with the electromagnet.

The invention has the beneficial effects that: when the anti-abrasion data line is used, data signals are directly transmitted through the spring wires of the two springs, charging current is transmitted out in a wireless mode in the wireless power transmitting module, and due to the shielding effect of the springs, wireless power can be transmitted to the wireless power receiving module at the joint end of the mobile phone only along the inner space of the springs, so that the wireless power receiving module is obtained by the joint of the mobile phone; because the spring is only used for transmitting digital signals, the insulation requirement is extremely low, an insulation sleeve which is easy to damage is not needed, and the spring cannot be damaged; and the electric energy transmission part does not adopt open line transmission, so the electric energy transmission part cannot be broken, and the whole data line is difficult to wear.

Detailed Description

The invention is further illustrated with reference to the following figures and examples:

the first embodiment is as follows:

in the first embodiment shown in fig. 1, the wear-resistant data line includes a USB connector 1 and a mobile phone connector 2, where the USB connector 1 and the mobile phone connector 2 respectively include two data contacts and two power contacts (conventional features, not shown), and the data contacts and the power contacts in the USB connector 1 and the mobile phone connector 2 are in one-to-one correspondence; the USB connector 1 and the mobile phone connector 2 are electrically connected through a spring 3, and the two springs 2 are coaxially arranged, so that the spring wires of the two springs 2 are abutted against each other and extend spirally in parallel; the two power contacts in the USB connector 1 are electrically connected to a wireless power transmitting module (not shown) in the USB connector, and the two power contacts in the mobile phone connector 2 are electrically connected to a wireless power receiving module (not shown) in the mobile phone connector; the

antennas

41 and 42 of the wireless power transmitting module and the wireless power receiving module are both arranged in the surrounding area of the spring 3.

In the data line, the wireless power transmitting module can be composed of a direct current oscillating circuit module, for example, various transistor oscillating circuits can be adopted, so that the integration level is high, the volume is small, and the cost is low; the wireless electric energy receiving module can be composed of an LC oscillating circuit, a voltage transformation module and a rectification filter module which are connected in sequence, so that the electric energy loss is small; the resonant frequency of each of the oscillating circuits is less than 3 x 10¹¹Hz is preferably such that the radio energy (i.e. electromagnetic waves) formed by it has a wavelength greater than 1mm, so that even with a suitable bending of the spring 3, the turns of the spring wire are no longer in close proximity to each other, which is sufficient to shield the radio energy.

The surface of the spring 3 is wrapped with an insulating layer, such as insulating paint. In the first embodiment, a soft shielding tube 5 with a metal coating on the surface is further disposed inside the spring 3, and may be made of tinfoil with a plastic film coated on the surface. The shielding tube 5 encloses the

antennas

41 and 42 of the wireless power transmitting module and the wireless power receiving module, so as to completely eliminate the leakage of wireless power and avoid the interference of electromagnetic waves to data transmission.

When the anti-abrasion data line is used, data signals are directly transmitted through the spring wires of the two springs 3, charging current is transmitted out in a wireless mode in the wireless power transmitting module, and due to the shielding effect of the springs 3, wireless power can be transmitted to the wireless power receiving module at the joint end of the mobile phone only along the inner space of the springs, so that the wireless power receiving module is obtained by the joint of the mobile phone; because the spring 3 is only used for transmitting digital signals, the insulation requirement is extremely low, an easily-damaged insulation sleeve is not needed, and the spring cannot be damaged; and the electric energy transmission part does not adopt open line transmission, so the electric energy transmission part cannot be broken, and the whole data line is difficult to wear.

Example two:

in the second embodiment shown in fig. 2, the spring 3 is made of iron wire, and the end of the handset connector 2 facing the spring 3 is provided with an electromagnet 6 with an insulated surface, and the shielding tube is not provided; the output end of the wireless power receiving module is divided into two paths, one path is electrically connected with a power contact in the mobile phone connector 2, and the other path is electrically connected with the electromagnet 6.

In the second embodiment, during the charging process, the electromagnet 6 is kept in the excited state, so that the electromagnet has a magnetizing effect on the spring 3, and therefore, the turns of iron wires which are no longer only close to each other due to the bending of the spring can be as close as possible under the action of magnetic force, that is, the severely bent spring is as straight as possible, so that the shielding performance of the spring 3 on wireless electric energy is enhanced.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
