[0020] Each of the three adapter circuit boards 7 has three connectors electrically mounted on it, and the three connectors are all of different types.

[0021] For details, please refer to the appendix of the instruction manual. Figure 2 As shown, the three connectors are Lightning connector 8, Type-C connector 9, and Micro-USB connector 10.

[0022] According to the above description, Lightning connector 8 is the traditional Apple mobile phone connector, Micro-USB connector is the traditional Android mobile phone connector, and TYPE-C connector 9 is the TYPE-C connector commonly used in electronic products.

[0023] In practical use, the present invention can be inserted into a compatible USB slot through the USB interface 2 to perform signal conversion. The signal output through the USB interface 2 is transmitted to the signal amplifier 4 through the primary wiring harness 3. The signal amplifier 4 amplifies the output electrical signal, and the amplified signal enters the adapter circuit board 7 of the adapter housing 6 through the secondary wiring harness 5.

[0027] Working principle: In actual use, the USB interface 2 can be inserted into a compatible USB slot for signal conversion. The signal output through the USB interface 2 is transmitted to the signal amplifier 4 through the primary wiring harness 3. The signal amplifier 4 amplifies the output electrical signal through its signal amplification circuit. The amplified signal then enters the adapter circuit board 7 of the adapter housing 6 through the secondary wiring harness 5, and can be connected to the corresponding device interface through the Lightning connector 8, TYPE-C connector 9, and Micro-USB connector 10, respectively. This completes the signal conversion, amplification, and transmission, achieving the normal operation of the signal converter of this utility model.

[0028] This utility model's signal converter is equipped with three different types of connectors: a Lightning connector 8, a Type-C connector 9, and a Micro-USB connector 10. This allows it to be used for signal conversion with most electronic products on the market, covering a wider range of electronic products. It effectively reduces the limitations of single-connector signal conversion and can be used for signal conversion or charging of different types of electronic products, thus having a wider range of applications and fewer limitations. Furthermore, the signal amplifier 4 effectively amplifies the output signal, thereby enhancing the converted signal and improving the signal conversion quality of this utility model's converter. It avoids excessive attenuation during signal transmission, resulting in higher quality performance. In addition, the overall structure is simple, portable, and more practical.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
