Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an anti-disengagement locking structure for a connector. Background Technology

[0002] A connector is a device used to achieve electrical connections, allowing circuits to be disconnected and reconnected to facilitate maintenance, upgrades, or replacements. Connectors are widely used in electronic equipment, communication systems, automobiles, aerospace, and other fields, and are indispensable components of modern electronic technology.

[0003] Traditional connectors typically insert the connector head directly into the socket, relying solely on the friction between the two. This connection is relatively unstable and is easily detached from the socket due to external forces or other environmental factors during use, thus affecting the normal operation of the equipment or causing safety accidents. Utility Model Content

[0004] (I) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to overcome the defects of poor connection stability and reliability of the above-mentioned connectors, and to provide a connector anti-disengagement locking structure.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a connector anti-disengagement locking structure, including a plug assembly and a socket. The plug assembly includes a housing first, a connecting plate first is provided on the outer side of the housing first, and a fixing block first is provided on both sides of the connecting plate first. The fixing block first is provided with a locking mechanism for preventing the plug assembly from falling off. The locking mechanism includes a locking tongue. A through hole is opened on the connecting plate first, and a groove is provided in the fixing block first that communicates with the through hole. The locking tongue is rotatably disposed in the groove, and one end of the locking tongue extends to the outside of the through hole. A spring first is connected to the inner wall of one side of the through hole, and one end of the spring first is connected to the locking tongue. The socket includes a housing second, and fixing blocks second are provided on both sides of the housing second. The fixing blocks second are provided with L-shaped slots that are adapted to the locking tongue.

[0008] As an improvement: the locking mechanism is provided in two sets. The connecting plate is provided with a sliding hole that communicates with the through hole. A pressing block is slidably provided in the sliding hole. The inner walls on both sides of the sliding hole are respectively provided with sliding grooves, and one end of the sliding groove extends into the through hole. A sliding plate is connected to the pressing block. The two ends of the sliding plate are respectively slidably located in the sliding groove.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0028] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0029] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0030] Connectors are prone to detachment due to external environmental factors during use. To avoid this, please refer to the attached... Figure 1 , Figures 3 to 6 As shown, a connector anti-disengagement locking structure includes a plug assembly and a socket. The plug assembly includes a housing 1, with a connecting plate 3 on the outer side of the housing 1. Fixing blocks 5 are respectively provided on both sides of the connecting plate 3. Each fixing block 5 has a locking mechanism to prevent the plug assembly from disengaging. The locking mechanism has two sets, each including a locking tongue 7. One end of the locking tongue 7 has a one-way tooth structure. A through hole 8 is provided on the connecting plate 3. A groove 9 communicating with the through hole 8 is provided in the fixing block 5. The locking tongue 7 is rotatably disposed within the groove 9, and one end of the locking tongue 7 extends to the outside of the through hole 8. A spring 10 is connected to the inner wall of one side of the through hole 8, and one end of the spring 10 is connected to the locking tongue 7. The socket includes a housing 2, with fixing blocks 2 6 on both sides of the housing 2. Each fixing block 2 6 has an L-shaped slot 11 adapted to the locking tongue 7. The opening of the slot 11 is a bevel structure matching the tooth surface of the locking tongue 7.

[0031] When the plug assembly is connected to the socket, during the process of inserting the locking tongue 7 into the slot 11, it rotates towards the end closer to the spring 10 under the action of the inclined surface of the slot 11 until the locking tongue 7 is fully inserted into the slot 11. After the locking tongue 7 is fully inserted into the slot 11, it fits perfectly with the slot 11 under the action of the spring 10, thereby locking the connection and preventing accidental dislodgement or loosening.

[0032] To facilitate quick and easy disconnection of the plug assembly from the socket, in conjunction with the attached... Figure 7 and Figure 8 As shown, the connecting plate 3 has a sliding hole 12 communicating with the through hole 8. A pressing block 13 is slidably disposed within the sliding hole 12. Sliding grooves 14 are respectively provided on the inner walls of both sides of the sliding hole 12, with one end of each groove extending into the through hole 8. A sliding plate 15 is connected to the pressing block 13, with both ends of the sliding plate 15 slidably positioned within the grooves 14. A second spring 16 is connected to the sliding plate 15, with one end of the second spring 16 connected to one inner wall of the groove 14. Pressing the pressing block 13 into the through hole 8 pushes the locking tongue 7 towards the spring 10, allowing the plug assembly to be pulled out of the socket.

[0033] To further improve the stability and reliability of the connection between the socket and the plug assembly, in conjunction with the attached... Figure 3 and Figure 5 As shown, the housing 2 is provided with a connecting plate 4, and the connecting plate 4 is provided with slots 17 at the four corners. The connecting plate 3 is provided with iron rods 18 at the corresponding positions of the slots 17. The slots 17 are equipped with magnets. The attraction of the magnets can ensure that the iron rods 18 are firmly held in the slots 17, and the connection can remain stable even under the action of external force to prevent accidental detachment. At the same time, the socket is provided with a connecting groove 19. The housing 1 is provided with a connecting shell 20 that mates with the connecting groove 19. The connecting shell 20 is inserted into the connecting groove 19, which increases the contact area between the two, thereby enhancing the friction and improving the reliability of the connection.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
