Description

A mobile phone data cable with a display

technical field

The utility model relates to the field of mobile phone charging data lines, and in particular provides a mobile phone data line with a display screen.

Background technique

A mobile phone data cable is a cable used to connect a mobile phone to a computer. The USB data cable is used for the connection and communication between the computer and the external equipment. In layman's terms, it is used for data transmission and charging. USB is the most widely used external bus standard in the PC field. It is used to regulate the connection and communication between computers and external devices. The USB interface supports the plug-and-play and hot-swap functions of devices. With the rapid development of computer hardware, the application of USB has increased the speed of data transmission between external devices. The biggest benefit of the increase in speed for users is that users can use more efficient external devices.

At present, the voltage of most mainstream mobile phone chargers is 5V, 1A, and that of tablet computers is 5V2.1A. The appearance color and appearance shape of many charger power supplies are very similar, and many charging connectors are also the same, so it is easy to take the wrong charging cable when charging. Plug the data cable for charging the tablet into the phone, and plug the charging cable for charging the phone into the tablet. Of course, there are standards for how much voltage and current amperage is equipped with which mobile phone. Manufacturers recommend using the original charger that comes with the mobile phone to charge the mobile phone, which guarantees the quality of charging and the service life of the mobile phone. Although non-original chargers can charge mobile phones, but now charger data line manufacturers are uneven, the scale is not the same, the selection of materials and equipment are different, so the quality of the mobile phone data lines produced is not the same, some data lines The voltage and current values exceed the standard, and the thickness of many copper wire materials used is not up to the standard, so it has an impact on the quality of mobile phone charging and the service life of the mobile phone. Sometimes unqualified mobile phone chargers and data cables may spontaneously ignite. Therefore, the market urgently needs to be safe and easy to identify, with a display to detect voltage and current values to satisfy users.

Utility model content

The technical problem to be solved by the utility model is to provide a mobile phone data line with a display screen to meet the problems raised by the above-mentioned background technology.

In order to achieve the above object, the utility model therefore provides the following technical solutions:

A mobile phone data line with a display screen of the utility model includes an input terminal, an output terminal and an IC chip. The left side of the head of the output terminal is connected by a housing, and a whole IC is arranged inside the housing chip, the IC chip is provided with a power module near the output terminal, a group of voltage detection modules and current detection modules arranged side by side are arranged on the left side of the power module, and a display screen is provided on the outer surface above the housing, and the display screen There are also letters V and A corresponding to the above, and there is a flashing light next to the letter A on the display screen, and a charging switch and a data transmission switch that can be slid to switch are also provided on the side of the housing.

As a further solution of the utility model: the mobile phone data line is made of environment-friendly PTE material and fireproof material.

As a further solution of the utility model: the material of the output end is treated with antirust.

Compared with the existing technology, the beneficial effect of the utility model is: because the quality of the current charger is poor, the production technology of the manufacturer is uneven, the quality of many data lines is not up to standard, and the charging current and voltage are too large, which will cause the internal reaction of the battery to intensify. Lithium will become extremely unstable, and it is possible to generate a huge gas, bursting the outer shell and causing an explosion. A bulging battery is caused by excessive current. Excessive charging current and voltage will not only cause damage to the battery, but even the mobile phone cannot withstand it, and even threaten your life safety. The mobile phone data line of the utility model is made of environment-friendly PTE material and fireproof material, and the material of the output end is treated with rust prevention. Greatly enhance the safety and service life of the data line. Secondly, through the intelligent program setting inside the IC chip, intelligently detect the voltage and current values, and read the corresponding values, so that the charging current and voltage can be displayed more intuitively and accurately on the display screen, which is easy to identify and grasp the charging status at any time. And current charging can be known at any time. If the voltage and current of different data lines are too large or too small, the internal program of the IC chip will remind the user of the value read by the flashing light, choose the charging line suitable for their own equipment, and improve the charging safety for the user. Respond to voltage and current in real time, avoid overcharging and causing harm to mobile phone equipment and personal, and let you enjoy the fun of technology in real time.
