[0018] In order to make the above purpose, features and advantages of the utility model more apparent, obvious, the specific embodiment of the utility model is explained in detail below with the drawings. In the following description, a lot of specific details are set forth to facilitate a full understanding of the utility model. But the utility model can be implemented in many other ways different from the description, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the following disclosed specific embodiments.

[0019] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or intervening elements can also be present. Where, when an element is referred to as being "connected" or "coupled" to another element, it can be directly connected or coupled to the other element or intervening elements can also be present. Where an element is referred to as being "a" or "an" "plurality" of items, this is intended to mean one or more of such items. The terms "top," "bottom," "left," "right," and the like as used herein are used for description only and do not indicate or imply any required or necessary orientation of the device.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "may" and "can" include any one of, or all of, the possible combinations of the aspects described herein.

[0021] The application will be described in greater detail with reference to the drawings, in which:

[0022] As shown in the drawings, in this embodiment, a locking connector Figs. 1-2

[0023] I. Overall structure assembly

[0024] First, the basic assembly of the connector is carried out. A plurality of pins are fixedly arranged in the inside of the female seat body 3 according to predetermined positions and manners. These pins are used for electrical connection with the plug, to ensure stable transmission of current or signals.

[0025] Then, the screw thread piece 2 is installed. The screw thread piece 2 is arranged around the plug-in end with the female seat body 3 as the center, and the screw thread on the inner wall of the screw thread piece 2 can effectively cooperate with the screw thread of the plug. The number of screw thread pieces 2 can be set according to actual needs, but it should be ensured that they are uniformly distributed to ensure uniform stress.

[0026] Next, the clamping ring 1 is screwed at the plug-in end of the female seat body 3. Initially, the clamping ring 1 can be in a relatively loose state, so as to facilitate subsequent plug insertion and screw thread piece 2 position adjustment.

[0027] II. Locking connector operation

[0028] When the plug is inserted into the female seat body 3, the screw thread piece 2 will have a certain initial fit due to the insertion of the plug. At this time, by tightening the clamping ring 1, the continuous rotation of the clamping ring 1 will cause the plug-in end of the female seat body 3 to be close.

[0029] ​During the continuous tightening of the clamping ring 1, the inner wall of the clamping ring 1 exerts a certain pressure on the outer side wall of the screw blade 2, so that the screw blade 2 is inwardly close, that is, the screw blade 2 is radially tightened. Since the inner side wall of the screw blade 2 is provided with a screw thread matched with the plug thread, the screw blade 2 is further tightly matched with the plug thread while being tightened, thereby enhancing the fastening force of the connection.

[0030] When the clamping ring 1 is continuously tightened until a predetermined fastening degree is reached, the screw blade 2 realizes efficient anti-loose fastening of the plug, preventing the plug from moving axially in the connector. Even when there are factors such as vibration and impact in the external environment, the stability of the connection between the plug and the connector can be ensured.

[0031] III. Application of other structures

[0032] When the connector is fixed on the electrical appliance, the plurality of limiting ring blocks 6 provided at the fixed end of the female seat body 3 play an important role. Since the limiting ring blocks 6 are arc-shaped structures, and the plurality of limiting ring blocks 6 are annularly arranged on the outer side wall of the female seat body 3, they form effective clamping and limiting with the mounting part of the electrical appliance. When trying to pull out the connector from the electrical appliance, the limiting ring blocks 6 will be hindered by the mounting part of the electrical appliance, effectively preventing the connector from being accidentally pulled out.

[0033] The anti-slip sleeve 4 fixedly arranged on the outer side wall of the female seat body 3 facilitates the user's grip on the connector during assembly and use. The anti-slip convex lines on the surface of the anti-slip sleeve 4 increase the friction between the hand and the connector, preventing operation errors caused by slippery hands during assembly.

[0034] During assembly, if it is necessary to rotate the clamping ring 1, the symmetrically arranged and mutually parallel cutting surfaces of the wrench clamping stop plate 5 can be used. Since the stop plate 5 is fixed to the female seat body 3, the relative rotation of the clamping ring 1 and the female seat body 3 can be accurately controlled by clamping the stop plate 5 with the wrench, achieving the tightening or loosening of the clamping ring 1, while preventing the connector from rotating itself during clamping of the stop plate 5, ensuring the accuracy and stability of the assembly.

[0035] Through the above specific embodiments, the anti-loose connector of the present application can meet the requirements for connection stability and reliability in different application scenarios, and has significant technical advantages and application value.

[0036] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described above, however, as long as the combination of the technical features does not exist contradictory, it should be considered as the scope of the description, for those of ordinary skill in the art, without departing from the concept of the present application, can make a number of variations and improvements, these are within the scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
