[0020] To make the objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0023] Example 1

[0024] See Figure 1 The main technical content of the first specific embodiment is shown. In the first embodiment, the technical solution includes a first spring 101, a second spring 201 and a moving part 300.

[0025] In this embodiment, the first connector 100 is a female connector and the second connector 200 is a male connector. The overall outer contour of the first connector 100 and the second connector 200 is cylindrical. In use, the second connector 200 is inserted into the first connector 100. A planar mounting platform is provided on the circumferential surface of the first connector 100 near the second connector 200.

[0026] Preferably, the first spring 101 is fixedly mounted on the mounting platform on the circumferential surface of the first connector 100 by screws, and the first spring 101 extends toward the second connector 200. The second spring 201 is disposed on the circumferential surface of the second connector 200. The first spring 101 can engage with the second spring 201. The moving member 300 is disposed on the first spring 101 or the second spring 201. In this embodiment, the moving member 300 is slidably mounted on the second spring 201. The moving member 300 can move toward or away from the first connector 100. The first spring 101 and the second spring 201 are in a state of rotational disengagement or elastic disengagement from engagement.

[0027] By providing a first spring piece 101 and a second spring piece 201 on the first connector 100 and the second connector 200 respectively, and using the movable component 300, the first connector 100 and the second connector 200 can achieve a stable connection after insertion through the snap-fit of the first spring piece 101 and the second spring piece 201, effectively preventing detachment due to external force or vibration and improving the reliability of the connection. Simultaneously, by moving the movable component 300, the first spring piece 101 and the second spring piece 201 can be quickly disengaged, enabling rapid disassembly of the first connector 100 and the second connector 200. This simplifies operation and improves the efficiency of maintenance and replacement.

[0028] Example 2

[0029] See Figures 1-3 The main technical content of the second specific implementation is shown. This embodiment is based on embodiment 1.

[0030] In some embodiments, the first spring 101 includes a first snap-fit portion 101a, which is arranged parallel to the first connector 100. The extension line of the first snap-fit portion 101a in its longitudinal direction is parallel to or intersects the extension line of the second connector 200 in its longitudinal direction, so that the first snap-fit portion 101a can better cooperate with the second spring 201, ensuring the stability and accuracy of the snap-fit. When the extension lines are parallel, a more uniform snap-fit force can be provided to ensure stability; when the extension lines intersect, a tighter snap-fit can be achieved.

[0031] In some embodiments, the extension line of the first snap-fit portion 101a in its longitudinal direction intersects the extension line of the second connector 200 in its longitudinal direction, and the intersection point of the extension line of the first snap-fit portion 101a in its longitudinal direction and the extension line of the second connector 200 in its longitudinal direction is located on the second connector 200. This makes the snap-fit position of the first snap-fit portion 101a and the second spring piece 201 more precise, and enables a stable connection within the effective range of the second connector 200. This avoids problems such as weak connection or stress concentration caused by improper snap-fit position, and improves overall performance and service life.

[0032] Preferably, the second spring piece 201 includes a body portion 201a. In this embodiment, the body portion 201a is annular in shape and is sleeved on the second connector 200, with the body portion 201a and the second connector 200 coaxially arranged. Designing the body portion 201a of the second spring piece 201 as annular and coaxially arranged with the second connector 200 allows the second spring piece 201 to be evenly distributed around the second connector 200, providing more stable support and a more secure locking effect. The annular body portion 201a can better adapt to the shape of the second connector 200, increasing the contact area.

[0033] Preferably, the second spring 201 includes a second snap-fit portion 201b, the extension line of the second snap-fit portion 201b in the longitudinal direction intersects the extension line of the second connector 200 in the axial direction on the second connector 200, so that the second snap-fit portion 201b can achieve precise snap-fit with the first snap-fit portion 101a of the first spring 101 at a specific position, thereby enhancing the reliability of the plug-in connector.

[0034] Furthermore, the main body 201a is fixedly mounted on the second connector 200, and the movable part 300 is slidably mounted on the main body 201a. The movable part 300 moves towards the first connector 100. During this process, the movable part 300 slides and presses against the second locking part 201b, causing the first spring piece 101 and the second spring piece 201 to disengage. By using the movable part 300 to slide and press against the second locking part 201b to disengage the first spring piece 101 and the second spring piece 201, the connection and disassembly process of the entire device becomes smoother and more reliable. The sliding operation of the movable part 300 is simple and convenient, enabling quick disengagement and improving the efficiency of connecting and disconnecting the connector.

[0035] Furthermore, the movable component 300 is elastically mounted on the second connector 200 via a spring. This elastic mounting method provides a certain degree of buffering and reset capability when the movable component 300 is subjected to external forces. When the movable component 300 is subjected to accidental impact or vibration during disassembly, the spring can absorb some of the energy, preventing the movable component 300 from undergoing a hard collision with the second spring plate 201 or other components, thereby protecting the structural integrity of the device. At the same time, the spring can also automatically adjust the position of the movable component 300 to a certain extent, allowing it to return to its initial position after disassembly, facilitating subsequent use and improving the operational convenience and reliability of the device.

[0036] In some embodiments, the second spring 201 is rotatably mounted on the second connector 200, and the second spring 201 rotates along its own circumference. The moving member 300 is slidably mounted on the second connector 200, and the moving member 300 is drive-connected to the second spring 201. The moving member 300 drives the second spring to rotate and disengage from the first spring. This increases operational flexibility. The rotatable second spring 201 makes the engagement and disengagement process more convenient. Simultaneously, the drive-connection design between the moving member 300 and the second spring 201 allows the operating force to be effectively transmitted to the second spring 201, achieving smooth and reliable rotational action, further improving the convenience and reliability of the connector assembly and disassembly.

[0037] The second connector 200 is provided with a first sliding groove 202, and the second spring piece 201 slides in conjunction with the first sliding groove 202.

[0038] The movable component 300 is provided with a slider 301, and the second spring piece 201 is provided with a second sliding groove 201c. The slider 301 is slidably connected to the second sliding groove 201c, ensuring reliable transmission between the slider 301 and the second spring piece 201. This connection method can also improve the motion synchronization between the movable component 300 and the second spring piece 201. When the movable component 300 moves axially, the second spring piece 201 rotates, causing the first spring piece 101 and the second spring piece 201 to disengage.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
