Description

Technical Field

[0001] The present invention relates to the technical field of connectors, in particular to a rectangular connector anti-loosening device. Background Art

[0002] Connectors, also known in China as connectors, plugs, and sockets, generally refer to electrical connectors. They connect two active components, transmitting current or signals. Connectors are a component that electronic engineers often come into contact with. Their function is quite simple: to bridge blocked or isolated circuits within a circuit, thus allowing current to flow.

[0003] After extensive searching, I discovered prior art publication number CN202997182U, which discloses a rectangular connector anti-loosening device. The upper end of the anti-loosening body is fixed to the bottom of the socket by screws, and the plug that matches the socket is inserted below the socket. The lower end of the anti-loosening body has left and right hooks that hang on the lower end of the plug to prevent it from falling off. It is easy to operate and the device will not cause the plug to fall off when the device is subjected to impact.

[0004] However, existing anti-loosening devices typically only prevent the plug from falling out when the device is impacted, but they cannot monitor the tightness of the connection between the plug and the socket in real time. A limitation of this design is that once the connection becomes loose, the user often cannot detect it in time, which can lead to problems such as unstable signal transmission, power interruption, and even device damage. Furthermore, most existing anti-loosening devices lack automatic adjustment functions and are unable to automatically compensate or issue an alarm when the connection becomes loose, further reducing the reliability and safety of the connector.

[0005] Therefore, based on the above search and in combination with the prior art, a rectangular connector anti-loosening device is proposed to solve the above problem. Summary of the Invention

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In a typical implementation of this application, please refer to Figures 1 to 8 As shown, a rectangular connector anti-loosening device includes: a plug 1, a socket 2 is provided on one side of the plug 1, two clamping blocks 3 are fixedly mounted on the side wall of the plug 1 facing the socket 2, connecting blocks 4 are fixedly mounted on the left and right side walls of the socket 2, and the two connecting blocks 4 have a clamping slot 5 on the side wall facing the clamping block 3. The two clamping blocks 3 slide in the two clamping slots 5 respectively. The top surfaces of the two connecting blocks 4 have a driving slot 6. An alarm 39 is fixedly mounted on the top surface of the plug 1. The alarm 39 is equipped with a buzzer or sound generator and can emit a high-decibel sound alarm.

[0031] Concave blocks 14, two concave blocks 14 are provided, and are respectively arranged on the socket 2 through a rotating mechanism;

[0032] Detection components: There are two groups of detection components, which are respectively arranged in two connection blocks 4.

[0033] The detection component includes: a limit rod 7, which is fixedly mounted on the inner wall of the card slot 5, a pressure sensor 8 is provided on the rear side wall of the limit rod 7, a sliding plate 9 is slidably mounted on the outer surface of the limit rod 7, a spring 10 is provided between the pressure sensor 8 and the sliding plate 9, an iron sheet 11 is fixedly mounted on the front side wall of the limit rod 7, a circular groove 12 is provided on the side wall of the card block 3 facing the sliding plate 9, a circular magnet 13 is fixedly mounted on the inner wall of the circular groove 12, and the circular magnet 13 is adsorbed on the iron sheet 11, and the detection component also includes an extrusion part.

[0034] As a preferred implementation in this embodiment, please refer to Figure 7 As shown, the extrusion part includes: an extrusion plate 33, which is arranged on the side wall of the concave block 14, and the surface of the extrusion plate 33 is nickel-plated. The side wall of the concave block 14 is provided with a mounting groove 34, and a connecting column 35 is fixedly installed on the inner wall of the mounting groove 34. A sliding column 36 is slidably installed inside the connecting column 35, and one side wall of the sliding column 36 is connected to the side wall of the extrusion plate 33, and the other side wall of the sliding column 36 is provided with a spring four 37, and the other end of the spring four 37 is connected to the inner wall of the connecting column 35. The inner wall of the mounting groove 34 is provided with a plurality of rectangular electromagnets 38, and the extrusion plate 33 is made of iron.

[0035] Through the above features, the plug 1 and the socket 2 can be preliminarily locked, and the tightness of the plug 1 and the socket 2 can be detected. If the connection between the plug 1 and the socket 2 is too loose, the squeezing plate 33 will slide out of the mounting groove 34, squeezing the plug 1. Specifically, when the staff inserts the plug 1 into the socket 2, the card block 3 will be inserted into the card groove 5. At this time, the card block 3 will squeeze the sliding plate 9, causing the spring between the pressure sensor 8 and the sliding plate 9 to contract. When the plug 1 and the socket 2 are fully inserted, the iron sheet 11 and the circular magnet 13 in the circular groove 12 are attracted to each other, so that the plug 1 and the socket 2 are preliminarily locked and prevented from loosening.

[0036] It is worth mentioning that when the plug 1 and the socket 2 are initially locked, the pressure on the pressure sensor 8 is stable. If loosening occurs, that is, the spring 10 moves the sliding plate 9 toward the plug 1 under the action of the rebound force, the pressure received by the pressure sensor 8 decreases, and the data is transmitted to the controller. The controller activates the alarm 39 and the rectangular electromagnet 38 in the spring 2 24 according to the data from the pressure sensor 8.

[0037] Specifically, when the card block 3 is inserted into the card slot 5, the rotating mechanism rotates the concave block 14 ninety degrees and performs a secondary locking on the plug 1 and the socket 2. After that, the rectangular electromagnet 38 is turned on, causing the extrusion plate 33 to move toward the front side wall of the plug 1. As the extrusion plate 33 moves, the sliding column 36 will extend from the connecting column 35 and cause the spring four 37 to be deformed under force. When the rectangular electromagnet 38 is powered off, the extrusion plate 33 is restored to the installation slot 34 by the rebound force of the spring four 37.

[0038] As a preferred implementation in this embodiment, please refer to Figure 5 and Figure 8 As shown, the rotating mechanism includes: a rotating column 15, which is rotatably connected to the side wall of the socket 2, and the outer surface of the rotating column 15 is connected to a connecting plate 16, and the side wall of the connecting plate 16 is provided with a moving groove 17. The rotating mechanism also includes a self-locking component and a driving component.

[0039] As a preferred implementation in this embodiment, please refer to Figure 5 and Figure 8 As shown, the self-locking assembly includes: a fixed column 18, which is fixedly mounted on the inner wall of the moving groove 17, a moving block 19 is slidably mounted on the outer surface of the fixed column 18, the top surface of the moving block 19 is nickel-plated, and the moving block 19 slides in the moving groove 17, and an L-shaped plate 20 is fixedly mounted on the side wall of the moving block 19. The side wall of the L-shaped plate 20 is connected to the side wall of the concave block 14, and the side wall of the connecting plate 16 is located above the moving groove 17 and is provided with a slide groove 21, which is connected to the moving groove 17, and the self-locking assembly includes a release member.

[0040] As a preferred implementation in this embodiment, please refer to Figure 6 As shown, the release member includes: a limit column 22, which is fixedly installed on the inner wall of the slide 21, a gravity block 23 is slidably installed in the middle of the limit column 22, and springs 24 are provided on both side walls of the gravity block 23. An adsorption magnet 25 is fixedly installed on the bottom surface of the gravity block 23, and a lifting groove 26 is provided on the side wall of the slide 21.

[0041] As a preferred implementation in this embodiment, please refer to Figure 8 As shown, the release member also includes: a limiting column 27, which is fixedly installed on the inner wall of the lifting groove 26, and a gravity block 28 is slidably installed on the outer surface of the limiting column 27. The gravity block 28 slides in the lifting groove 26, and a spring 3 29 is provided on the bottom surface of the gravity block 28. A lifting plate 30 is fixedly installed on the side wall of the gravity block 28.

[0042] As a preferred implementation in this embodiment, please refer to Figure 1 and Figure 2As shown, the driving assembly includes: a gear 31, which is fixedly sleeved on the outside of the rotating column 15, and the gear 31 is located above the driving slot 6. A toothed belt 32 is fixedly installed on the top surface of the block 3, and the toothed belt 32 is engaged with the gear 31.

[0043] By virtue of the above features, the concave block 14 can be made to fall onto the top surface of the plug 1 while the card block 3 is inserted into the card slot 5, thereby performing a secondary locking on the connection between the plug 1 and the socket 2. Specifically, when the staff inserts the card block 3 into the card slot 5, the toothed belt 32 on the top surface of the card block 3 engages with the gear 31, and in the process of pushing, the rotating column 15 rotates ninety degrees, and the connecting plate 16 on the rotating column 15 rotates ninety degrees synchronously, and then the connecting plate 16 rotates ninety degrees. When the weight block 19 is lowered to the center of the slide groove 21, the weight block 13 is restored to the center of the slide groove 21 under the action of the two springs 24, so that the adsorption magnet 25 on the bottom surface of the weight block 13 no longer contacts the top surface of the moving block 19, but contacts the top surface of the fixed column 18. Then the weight block 28 no longer adsorbs the moving block 19, so that the moving block 19 moves downward under the action of gravity. When the moving block 19 moves downward, the L-shaped plate 20 and the concave block 14 move downward synchronously, so that the concave block 14 locks the top surface of the plug 1.

[0044] In addition, when the connecting plate 16 rotates ninety degrees, the gravity block 2 28 will move downward in the lifting slot 26 and squeeze the spring 3 29, so that the lifting plate 30 connected to the gravity block 28 pushes the moving block 19 downward to avoid the suction force of the adsorption magnet 25 being too large, so that the gravity block 1 23 cannot return to the center of the slide slot 21, resulting in the moving block 19 being unable to fall.

[0045] Working principle:

[0046] During use, first insert plug 1 into socket 2. When the clamping block 3 is inserted into the slot 5, it compresses the sliding plate 9, causing spring 10 between the pressure sensor 8 and the sliding plate 9 to contract. When plug 1 and socket 2 are fully inserted, the iron plate 11 attracts the circular magnet 13 in the circular slot 12, completing the initial locking and preventing the plug 1 and socket 2 from loosening. At this point, the toothed belt 32 on the top surface of the clamping block 3 engages with the gear 31. As the clamping block 3 pushes, the gear 31 drives the rotating column 15 to rotate 90 degrees. The connecting plate 16 on the rotating column 15 rotates 90 degrees synchronously. As the connecting plate 16 rotates 90 degrees, the weight block 1 23, under the action of the two springs 2 24, returns to the center of the sliding slot 21. At this point, the attracting magnet 25 on the bottom surface of the weight block 1 23 no longer contacts the top surface of the moving block 19, but instead contacts the top surface of the fixed column 18. Consequently, the weight block 2 28 no longer attracts the moving block 19, and the moving block 19 moves downward under the action of gravity. As the movable block 19 moves downward, the L-shaped plate 20 and the concave block 14 move downward synchronously, causing the concave block 14 to perform a secondary locking operation on the top surface of the plug 1. Simultaneously, as the connecting plate 16 rotates 90 degrees, the second gravity block 28 moves downward in the lifting slot 26, compressing the third spring 29. The lifting plate 30, connected to the second gravity block 28, pushes the movable block 19 downward to prevent the excessive suction force of the adsorption magnet 25 from preventing the first gravity block 23 from returning to the center of the slide slot 21, thereby preventing the movable block 19 from falling. If the connection between the plug 1 and the socket 2 becomes loose, the rebound force of the first spring 10 causes the sliding plate 9 to move toward the plug 1. At this point, the pressure on the pressure sensor 8 decreases, and the pressure sensor 8 transmits data to the controller. Based on the data from the pressure sensor 8, the controller activates the alarm 39 and the rectangular electromagnet 38. Once the rectangular electromagnet 38 is activated, the compression plate 33 moves toward the front wall of the plug 1. As the extrusion plate 33 moves, the sliding post 36 extends from the connecting post 35 and deforms the spring 29 37. When the rectangular electromagnet 38 is de-energized, the extrusion plate 33 returns to the mounting slot 34 due to the resilience of the spring 29 37.

[0047] Through the above-described operating principle, the present invention can achieve dual locking of the plug 1 and the socket 2, and issue an alarm and automatically adjust when the connection is loose, thereby ensuring the reliability of the connection. The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, can make equivalent substitutions or modifications based on the technical solution and inventive concept of the present invention shall be covered by the scope of protection of the present invention.
