For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] like Figure 1 and Figure 2 As shown, a connector rotation fixing structure includes a housing 10 and a plug 20. The plug 20 is mounted on the rear of the housing 10. In this embodiment, the plug 20 and the rear of the housing 10 are interference fit, but the interference between the plug 20 and the housing 10 is small. After a rotational force is applied to the plug 20, the plug 20 can rotate relative to the rear of the housing 10. A plurality of latching keys 11 are provided on the outer side wall of the rear of the housing 10. The plug 20 has a plurality of latching keys 11 in the axial direction. 1, and the slot 21 extends from the tail to the head, and a rotation groove is opened on the circumferential side wall of the head of the slot 21 along the circumferential direction, and the key 11 is stuck in the rotation groove. When the plug 20 is installed, the slot 21 of the plug 20 is aligned with the key 11 of the shell 10, and then the plug 20 is sleeved on the tail of the shell 10, and then a rotation force is applied to the plug 20, the plug 20 rotates, and the key 11 rotates toward the rotation groove, so that the slot 21 is stuck in the rotation groove.

[0030] In this embodiment, if Figure 4 As shown, the head of the key 11 is a wedge-shaped head 13, and the tail of the key 11 is a stop end surface 12. Figure 5 and Figure 6 As shown, the rotating groove includes a narrow groove 22 and a receiving groove 23. The width of the wedge-shaped head 13 is smaller than the width of the narrow groove 22, and the width of the tail of the receiving groove 23 is larger than the width of the narrow groove 22. The key 11 is squeezed through the narrow groove 22 and enters the receiving groove 23. In this embodiment, the key 11 has a bullet head structure on the vertical projection surface, and a stop step 24 is formed between the receiving groove 23 and the narrow groove 22. After the plug 20 rotates in the opposite direction, the stop step 24 abuts against the stop end face 12. After the wedge-shaped head 13 enters the narrow groove 22, The wedge-shaped head 13 applies an extrusion force to the narrow groove 22. Due to the existence of the card slot 21, a side wall of the narrow groove 22 close to the slot 21 can be opened outward, so that the wedge-shaped head can pass through the narrow groove 22. After the wedge-shaped head passes through the narrow groove 22, the narrow groove 22 is reset, so that after the plug 20 rotates in the opposite direction, the stop step 24 can abut against the stop end face 12, thereby preventing the card key 11 from being separated from the accommodating groove 23, thereby ensuring the reliability of the installation of the plug 20 and the rear end of the housing 10. In this embodiment, Figure 3 As shown, there are two latches 11, and the two latches 11 are evenly distributed on the same circumference. Furthermore, the maximum width of the wedge-shaped head 13 is 0.5 mm to 1.5 mm larger than the width of the narrow groove 22, thereby ensuring that when the wedge-shaped head 13 squeezes the narrow groove 22, the narrow groove 22 can be deformed to provide an outflow space for the wedge-shaped head 13 to pass through, and can also prevent the narrow groove 22 from being deformed too much or breaking. After the wedge-shaped head 13 passes through the narrow groove 22, the narrow groove 22 can be reset.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
