Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector with an anti-loosening structure. Background Technology

[0002] With the widespread application of electronic devices and smart devices in various industrial and civilian scenarios, connectors, as important components for the transmission of electrical signals and power, directly affect the reliability and service life of equipment operation due to their structural safety and connection stability. Especially in environments with high vibration, frequent insertion and removal, or movement, traditional connectors are prone to problems such as loosening, poor contact, or detachment, making it urgent to improve connection robustness through structural innovation.

[0003] Existing connectors typically employ a plug-in mechanical connection method, using friction, snap-fit ​​mechanisms, or elastic structures to achieve the mating and positioning of the plug and socket. Some high-end models also incorporate rotational locking or threaded fixing structures to enhance connection stability. However, these methods are often structurally complex, inconvenient to assemble, and prone to fatigue loosening during long-term use, leading to a decrease in reliability.

[0004] However, the lack of a structure that automatically drives the locking mechanism to prevent loosening during the connection process means that the connector still has the risk of loosening during use, and the connection efficiency and stability cannot be balanced. Therefore, a connector with an anti-loosening structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a connector with an anti-loosening structure, which aims to improve the problem that traditional connector fixing structures are often complex, inconvenient to assemble, and prone to fatigue loosening during long-term use, resulting in a decrease in reliability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a connector with an anti-loosening structure, comprising a connector socket and a connector plug, wherein a connector head is provided on the side of the connector plug near the connector socket, the outer wall of the connector head is slidably connected to the inside of the connector socket, and a locking component is installed inside the connector socket;

[0007] The engaging assembly includes a connecting post, the outer wall of which is rotatably connected to the inside of the connector socket. A gear is fixedly connected to the outer wall of the connecting post, and a C-shaped plate is fixedly connected to the outer wall of the connecting post. The outer wall of the C-shaped plate is slidably connected to the inside of the connector plug. A rack is fixedly connected to one side of the outer wall of the connector head, and the rack meshes with the tooth end of the gear.

[0008] Furthermore, a sliding plate is slidably connected to the inner wall of the connector plug, and a locking block is fixedly connected to one side of the outer wall of the sliding plate.

[0009] Furthermore, a spring is fixedly connected to the other side of the outer wall of the sliding plate, and a telescopic rod is provided inside the spring.

[0010] Furthermore, a limiting block is fixedly connected to the inner sidewall of the connector plug near the outer side of the sliding plate, and the sidewall of the sliding plate is slidably connected to the outer wall of the limiting block.

[0011] Furthermore, a guide block is fixedly connected to the outer wall of the connector head, and a T-shaped slot is provided inside the connector socket. The outer wall of the guide block is slidably connected to the inner wall of the T-shaped slot.

[0012] Furthermore, the outer wall of the card block is disposed through the inside of the connector plug, and the outer wall of the card block is slidably connected to the inside of the C-shaped plate.

[0013] Furthermore, a connecting plate is fixedly connected to one side of the outer wall of the sliding plate, and the outer wall of the connecting plate is slidably connected to the inside of the connector plug.

[0014] Furthermore, one end of the telescopic rod is fixedly connected to the inner wall of the connector plug, and the other end of the telescopic rod is fixedly connected to one side of the outer wall of the sliding plate.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, when the connector head on one side of the connector plug is inserted into the connector socket for connection, the rack and gear on one side of the connector head mesh and rotate. At this time, the rotation of the gear can drive the C-shaped plate on the outside of the connector post to rotate. When the connector head is inserted into the connector socket for connection, the C-shaped plate can be driven to engage inside the connector plug to prevent the connector socket and connector plug from becoming loose, thereby improving the practicality of the connector.

[0017] 2. In this utility model, after the C-shaped plate is inserted into the connector plug, the C-shaped plate pushes the locking block, which in turn causes the spring's reaction force to push the locking block into the C-shaped plate. The locking block's insertion into the C-shaped plate achieves a double fixation effect to prevent the C-shaped plate from detaching. By pulling the connecting plate, the locking block is disengaged from the C-shaped plate, making it easy to remove the locking block from the C-shaped plate, thereby improving the connector's practicality.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1-6 This utility model provides an embodiment of a connector with an anti-loosening structure, comprising a connector socket 1 and a connector plug 2. A connector head 3 is provided on the side of the connector plug 2 near the connector socket 1. The outer wall of the connector head 3 is slidably connected to the inside of the connector socket 1, for realizing the mating of the connector plug 2 and the connector socket 1, ensuring electrical continuity. A locking assembly is installed inside the connector socket 1 to realize the anti-loosening and fixing function in the connected state. The locking assembly includes a connecting post 4, the outer wall of which is rotatably connected to the inside of the connector socket 1, for realizing... The device features a rotary locking function. A gear 5 is fixedly connected to the outer wall of the connecting post 4. The gear 5 engages with the rack 7 on the plug side to transmit power. A C-shaped plate 6 is fixedly connected to the outer wall of the connecting post 4. The outer wall of the C-shaped plate 6 is slidably connected inside the connector plug 2. It is used to insert into the plug during connection to form an inner wall engagement, preventing the connector from loosening or accidentally separating. A rack 7 is fixedly connected to one side of the outer wall of the connector head 3. The rack 7 engages with the tooth end of the gear 5. During plug insertion, the rack 5 rotates, thereby driving the connecting post 4 and the C-shaped plate 6 to rotate synchronously, achieving engagement and fixation.

[0028] Specifically, the above structure utilizes the meshing action of rack 7 and gear 5 during the insertion of connector plug 2 into connector socket 1 to rotate and engage the connecting post 4 and C-shaped plate 6 on the inner wall of the plug, forming a physical anti-loosening limiting structure. This structure can complete the synchronous action of connection and locking without adding extra operating steps, thereby improving the connection efficiency and stability of the connector. It is suitable for electrical connection application scenarios under complex working conditions such as vibration and high-frequency insertion and removal.

[0029] Reference Figures 1-6 A sliding plate 8 is slidably connected to the inner wall of the connector plug 2 to allow for adjustable movement of the internal structure of the plug, in conjunction with the action of the anti-loosening mechanism. A locking block 9 is fixedly connected to one side of the outer wall of the sliding plate 8. The outer wall of the locking block 9 extends through the interior of the connector plug 2 and is slidably connected to the interior of the C-shaped plate 6. This allows the locking block 9 to engage or disengage from the C-shaped plate 6 during the movement of the sliding plate 8, achieving a reliable limiting or releasing function. A spring 10 is fixedly connected to the other side of the outer wall of the sliding plate 8 to provide a reset force, ensuring that the sliding plate 8 maintains its initial position when not inserted. A telescopic rod 11 is provided inside the spring 10. One end of the telescopic rod 11 is fixedly connected to the inner wall of the connector plug 2, and the other end is fixedly connected to one side of the outer wall of the sliding plate 8. This guides the sliding plate 8 to move along a specific path, improving sliding accuracy and structural stability. The inner wall of the connector plug 2 is close to the sliding plate 8. A limiting block 13 is fixedly connected to the outer side to effectively limit the movement range of the sliding plate 8. The side wall of the sliding plate 8 is slidably connected to the outer wall of the limiting block 13 to ensure that the sliding plate 8 slides within a predetermined trajectory and prevents it from deviating or coming off. A guide block 14 is fixedly connected to the outer wall of the connector head 3. A T-shaped slot 15 is provided inside the connector socket 1. The outer wall of the guide block 14 is slidably connected to the inner wall of the T-shaped slot 15, thereby achieving precise guidance and positioning during the docking of the plug and socket, and improving the stability and coaxiality of the connector insertion. A connecting plate 12 is fixedly connected to one side of the outer wall of the sliding plate 8. The outer wall of the connecting plate 12 is slidably connected to the inside of the connector plug 2 to provide reinforced support for the sliding plate 8 and improve the overall mechanical strength and engagement accuracy.

[0030] Specifically, through the coordinated operation of the sliding plate 8, the locking block 9, the spring 10, and the telescopic rod 11, when the connector plug 2 is inserted into the socket, the limit locking and reset control of the C-shaped plate 6 is automatically realized, thereby ensuring that the locking block 9 is stably embedded and the connection is firm in the connected state, effectively preventing the connector from loosening due to vibration or pulling, and significantly improving the safety and reliability of the connection system under complex working conditions.

[0031] Working principle: When the connector is needed, first insert the connector head 3 into the connector socket 1. After the rack 7 meshes with the gear 5, the C-shaped plate 6 on the outside of the connector post 4 is driven to engage inside the connector plug 2. At this time, the C-shaped plate 6 pushes the locking block 9 to retract into the connector plug 2. Then, through the reaction force of the spring 10, the locking block 9 is driven into the C-shaped plate 6 for fixation. At the same time, when the connector head 3 is inserted into the connector socket 1, the guide block 14 is inserted into the inner wall of the T-shaped slot 15, thereby guiding the connector plug 2. When disassembly is required, pull the connecting plate 12 to drive the locking block 9 on one side of the sliding plate 8 to disengage from the C-shaped plate 6. By pulling the connector plug 2, the C-shaped plate 6 is driven out of the connector plug 2 for easy disassembly.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
