[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figures 1 to 8 , is an anti-loosening connector structure of an embodiment of the utility model, comprising a first connector 10, and a second connector 20 matched to the first connector,

[0030] The first connector 10 includes a first connector body 11, a first pair of contacts 12 coaxially connected to the end of the first connector body 11, and a first conductive terminal 13 coaxially connected to the inside of the first pair of contacts 12. Figure 4 As shown, the end of the first pair of joints 12 is evenly spaced along its circumference with a plurality of positioning openings 121, which are used to position and connect the second connector 20. A barb portion 122 is provided on the outer circumferential surface of the first pair of joints 12 at one side corresponding to each positioning opening 121, and a snap-fit ​​groove 123 is formed between two adjacent barbs 122 and the outer circumferential surface of the first pair of joints 12.

[0031] The second connector 20 includes a second connector body 21, a second pair of connectors 22 coaxially connected to the end of the second connector body 21, a second conductive terminal 23 coaxially connected to the second pair of connectors 22, a locking ring 24 rotatably sleeved on the second pair of connectors 22, and a return spring 25 installed between the second pair of connectors 22 and the locking ring 24; one end of the return spring 25 abuts against the second pair of connectors 22, and the other end of the return spring 25 abuts against the locking ring 24, and the return spring 25 drives the locking ring 24 to automatically buckle the first pair of connectors 12 to achieve an anti-loose connection between the second connector 20 and the first connector 10. Among them, the second pair of connectors 22 abut against the first pair of connectors 12, the second conductive terminal 23 matches and inserts the first conductive terminal 13, and one end of the locking ring 24 protrudes beyond the second pair of connectors 22 and is used to buckle the first pair of connectors 12 to achieve an anti-loose connection between the second connector 20 and the first connector 10.

[0032] Specifically, Figure 3 As shown, a positioning column 221 protrudes outward from one end surface of the second pair of joints 22, and the positioning column 221 is used to insert the positioning hole 121 to achieve accurate positioning. Two slide grooves 222 are arranged on the outer circumferential surface of the second pair of joints 22 at intervals along the circumferential direction thereof, and the two slide grooves 222 are symmetrical about the center of the second pair of joints 22. A notch 223 is arranged on the second pair of joints 22 corresponding to the side of each slide groove 222 away from the first pair of joints 12.

[0033] like Figure 5As shown, the lock ring 24 includes a ring body 241, a plurality of locking blocks 242 evenly spaced circumferentially along the inner wall of one end of the ring body 241, two sliders 243 circumferentially arranged along the inner wall of the other end of the ring body 241, and a stopper 244 located between the two sliders 243. The sliders 243 correspond to the notches 223 one by one, and the width of the sliders 243 is smaller than the opening width of the notches 223, so as to ensure that the lock ring 24 can rotate smoothly on the second pair of joints 22. In addition, the interior of one slide groove 222 is used to accommodate the reset spring 25, and the interior of the other slide groove 222 is used to accommodate the stopper 244, so that the lock ring 24 and the second pair of joints 22 can automatically rotate and reset after relative rotation, and the locking block 242 is driven to buckle with the interior of the buckling groove 123 through automatic rotation and reset, that is, the barb 122 is used to abut the locking block 242 to achieve locking and effectively prevent loosening.

[0034] When the first connector 10 is matched and connected with the second connector 20, the user only needs to manually rotate the locking ring 24 to compress the reset spring 25, and then pass the first pair of connectors 12 through the locking ring 24 and dock with the second pair of connectors 22. At this time, the positioning port 121 is matched and engaged with the positioning column 221, and the locking block 242 just enters the outermost side of the snap-fit ​​groove 123. Then, release your hand, the reset spring 25 returns to its original length, and drives the locking ring 24 to rotate. At this time, the locking block 242 moves to the innermost side of the snap-fit ​​groove 123 and is restricted by the barb 122. The interaction between the barb 122 and the locking block 242 is used to achieve a stable locking, thereby preventing the first connector 10 and the second connector 20 from loosening, ensuring the stable connection between the first connector 10 and the second connector 20, and effectively ensuring the safety and reliability of the system.

[0035] In this embodiment, a first guide bevel is provided on the side of the hook portion 122 close to the positioning port 121, and a second guide bevel is provided on the side of the locking block 242 facing away from the first guide bevel. Through the design of the first guide bevel and the second guide bevel, the locking block 242 can enter the interior of the snap-fit ​​groove 123 more smoothly, thereby further improving the usability of the connector.

[0036] The above-mentioned anti-loosening connector structure has a simple structure and is easy to use. The second connector 20 is rotatably connected to a locking ring 24, and the locking ring 24 is driven by a reset spring 25 to automatically buckle with the first connector 10, ensuring a stable connection between the first connector 10 and the second connector 20, effectively ensuring the safety and reliability of the system.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
