[0022] Specifically, as Figure 1As shown in the figure, in the USB-based data conversion device of this embodiment, it includes: a USB wiring module 20 and a USB to twisted pair module 10, where

[0023] The USB wiring module 20 includes a first housing, a four-hole wiring terminal provided at the first end of the first housing, and a USB female head 21 provided at the second end of the first housing. Electrodes corresponding to the USB female head 21 are provided in the four-hole wiring terminal to distribute the four-wire data cable accessed by the four-hole wiring terminal to the USB female head 21, so as to be transmitted to the USB to twisted pair module 10 through the connection between the USB female head 21 and the USB male head 11.

[0024] The USB to twisted pair module includes a second housing, a two-hole wiring terminal 12 provided at the first end of the second housing, a USB male head 11 provided at the second end of the second housing, and a conversion circuit board provided in the second housing.

There are four first positioning holes 202 and two second positioning holes 102, and they are arranged side by side respectively. Fixing screws are screwed in both the first positioning holes 202 and the second positioning holes 102. The fixing screws can extend into the corresponding wiring holes. By tightening the fixing screws, the wires embedded in the wiring holes can be fixed. Furthermore, wiring can be carried out at any time according to actual needs, without the need to customize communication cables with connectors in advance according to the communication distance requirements. In actual applications, only twisted pairs and four-wire communication cables with sufficient length need to be prepared.

[0028] Considering the convenience of applying force, in this embodiment, the ring groove 201 is provided near the second end of the first housing, and at least one is provided at intervals along the direction from the first end to the second end of the first housing. While facilitating the application of force, it can ensure the structural integrity around the first positioning hole 202, ensure the fixing reliability of the fixing screw, and further ensure the fixing reliability of the data cable.

[0029] To facilitate the installation of the conversion circuit board, in this embodiment, the second housing includes a main body and a top cover 101. The extended length of the top cover 101 is less than that of the main body, and one end of the top cover 101 is flush with the second end of the second housing, so that the fixing screw corresponding to the two-hole wiring terminal 12 is provided on the main body, which can ensure the fixing reliability of the fixing screw. And it can expose three sides of the top cover 101, facilitating the disassembly operation of the top cover 101, so that when a fault occurs in the internal conversion circuit board, the top cover 101 can be conveniently removed for repair and replacement.

[0030] To improve the communication reliability, in an alternative embodiment, a third housing is further provided. The size of the third housing is larger than the sum of the first housing and the second housing to protect the first housing and the second housing inside the third housing. Openings are provided at both ends of the third housing for the four-wire data cable and the twisted pair to lead out, and waterproof plugs are provided to prevent water vapor from invading and damaging the electronic circuit. The third housing can adopt an upper and lower mold splicing structure, and the openings are respectively arranged on the upper and lower shells, and a complete through hole is formed with the completion of the mold closing, which can facilitate wiring and the setting of waterproof plugs. A sealing rubber ring can also be provided at the mold closing line position to improve the waterproof performance.

[0031] And in this embodiment, the fixing screw corresponding to the two-hole wiring terminal is provided on the top surface of the main body of the second housing, where the structural strength is sufficient to ensure the fixing effect on the twisted pair.

[0032] The present utility model further provides a communication device, including the above-mentioned USB-based data conversion device, and the four-hole wiring terminal of the first data conversion device is communicatively connected to the corresponding device host through a four-wire data cable, and the two-hole wiring terminal is communicatively connected through a twisted pair, that is, the conversion circuit board can perform two-way conversion and simultaneously realize data sending and data receiving, which can reduce the transceiver matching requirements.
