[0024] In the above technical solution, considering that there are upper and lower shells of a traditional USB connector, which are firmly installed and not easy to open, this may bring some inconveniences. If the inside of the connector needs to be cleaned, inspected or repaired, since the upper and lower shells are not easy to open, it may take more time and effort to disassemble the connector, which may increase the complexity of the maintenance process. To solve such problems, the specific operations are as follows: By setting a fixing component inside the upper shell 3, the upper shell 3 and the lower shell 4 wrap and connect the interface body 1 together, and then use the fixing component to fix the lower shell 4, so as to fix the upper and lower shells together to complete the shell installation.

Then, under the action of the sliding rod 10, the fixed block 15 and the connecting plate 8 will be pushed to move, allowing the fixed block 15 to disengage from the card slot 19, and then the upper housing 3 and the lower housing 4 can be separated for viewing or maintenance. Under the action of the second spring 20, the connecting rod 16, the pressing plate 17 and the pressing block 18 will be reset. When closing the upper housing 3 and the lower housing 4, first place the connecting wire 2 in the middle of the clamping block 5, then align the positioning post 7 with the positioning cylinder 6, and then close the upper housing 3 and the lower housing 4. The inclined surface of the fixed block 15 will abut against the edge of the lower housing 4. Continue to press forcefully to push the fixed block 15 away, and the first spring 12 will be compressed. When the upper housing 3 and the lower housing 4 are completely closed, the first spring 12 will push the connecting plate 8 to reset, so that the fixed block 15 re-enters the card slot 19, thereby fixing the upper and lower housings together. The operation is simple, which improves the maintenance efficiency and use convenience of the connector.

[0027] Working principle: During use, when it is necessary to open the housing, press the pressing block 18 forcefully, thereby driving the pressing block 18 to move inside the notch 13, and then driving the connecting rod 16 and the pressing plate 17 to move, so that the pressing plate 17 moves out of the placement groove 14 and abuts against one side of the fixed block 15. Then, under the action of the sliding rod 10, the fixed block 15 and the connecting plate 8 will be pushed to move, allowing the fixed block 15 to disengage from the card slot 19, and then the upper housing 3 and the lower housing 4 can be separated for viewing or maintenance. Under the action of the second spring 20, the connecting rod 16, the pressing plate 17 and the pressing block 18 will be reset. When closing the upper housing 3 and the lower housing 4, first place the connecting wire 2 in the middle of the clamping block 5, then align the positioning post 7 with the positioning cylinder 6, and then close the upper housing 3 and the lower housing 4. The inclined surface of the fixed block 15 will abut against the edge of the lower housing 4. Continue to press forcefully to push the fixed block 15 away, and the first spring 12 will be compressed. When the upper housing 3 and the lower housing 4 are completely closed, the first spring 12 will push the connecting plate 8 to reset, so that the fixed block 15 re-enters the card slot 19, thereby fixing the upper and lower housings together.
