Description

Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to an anti-detachment plug for chargers. Background Technology

[0002] Mobile phone chargers can be broadly categorized into travel chargers, desktop chargers, and maintenance chargers. Most users are familiar with the first two types, while travel chargers are the most commonly sold on the market. Mobile phone chargers, also known as mobile phone adapters, are essentially composed of a stable power supply (mainly a regulated power supply that provides a stable operating voltage and sufficient current) plus necessary constant current, voltage limiting, and time limiting control circuits.

[0003] Utility model CN219892999U discloses a mobile phone charger with a protective structure, including a charger body and a data cable. One end of the charger body is electrically connected to a metal plug, and the data cable is plugged into the other end of the charger body. The plug-in end of the charger body is equipped with a fixing anti-detachment mechanism, and the two ends of the fixing anti-detachment mechanism are respectively abutted against both sides of the data cable. A drop-proof frame is fitted on the outer side of the charger body, and two symmetrically arranged buffer mechanisms are fixedly connected between the two side walls of the charger body and the two inner walls of the drop-proof frame. This utility model's mobile phone charger with a protective structure, by setting a fixing anti-detachment mechanism, uses the elastic force of a clamping spring to press the two clamping blocks against the data cable for fixation, preventing the data cable from detaching from the charger body. The operation is simpler, the fixing effect is more stable, and the setting of buffer mechanisms and drop-proof frame improves the drop protection of the charger body.

[0004] The device disclosed in the above utility model clamps the data cable through the arc-shaped groove on the clamping block. When the cross-sectional size of the data cable does not match the size of the arc-shaped groove, the two are in a clamping state, which limits the clamping stability of the data cable. Furthermore, the device can only maintain the connection between the data cable and the charger body, but cannot press the data cable firmly onto the charger body, which may result in poor contact. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-detachment plug for a charger, so as to solve the problem mentioned in the background art that the data cable cannot be pressed tightly onto the charger body, which may result in poor contact.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a charger anti-detachment plug, comprising a charger body and a data cable, wherein a protective shell is fitted onto the charger body, one end of the protective shell near the plug is open, and the other end is provided with an extension shell, the interface of the data cable is located inside the extension shell, a rotating wheel is provided on the outer wall of the extension shell, a threaded rod is connected to the axis of the rotating wheel, the threaded rod is rotatably connected between the extension shell and the protective shell, a movable plate is threadedly connected to the threaded rod, the movable plate is located outside the data cable interface, and a pressure plate is slidably provided on it, the pressure plate is in contact with the outer wall surface of the data cable interface.

[0007] Preferably, the movable plate, the extension shell, and the protective shell are all provided with connection slots, and the size of the connection slots is larger than the size of the data cable interface.

[0008] Preferably, the extension shell and the protective shell are connected by a limiting rod, and one end of the movable plate is slidably connected to the limiting rod.

[0009] Preferably, there are two pressure plates, which are symmetrically distributed on both sides of the charger body, and each pressure plate is provided with an L-shaped push rod, the top of which is located on the outside of the extension shell.

[0010] Preferably, the extended shell has two movable slots, and each of the two L-shaped push rods is provided with a connecting shaft, which is slidably adapted to the movable slot.

[0011] Preferably, the lengths of both connecting shafts are greater than the distance from the bottom wall of the top of the L-shaped push rod to the bottom of the moving groove.

[0012] Preferably, the protective shell has an internal silicone layer.

[0013] The beneficial effects of this utility model are: In this invention, a rotating wheel drives a threaded rod to rotate synchronously, which in turn drives a moving plate to move synchronously. This causes the moving plate to move a pressure plate against the data cable interface, moving the data cable interface towards the socket of the charger body until the data cable interface is inserted into the socket. This achieves a tight connection between the data cable and the charger body. At the same time, through the contact relationship between the pressure plate and the data cable interface, the pressure plate can hold the data cable interface against the charger body, preventing the data cable from falling off the charger body or making poor contact. This effectively improves the stability of the connection between the data cable and the charger body. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 A charger anti-detachment plug includes a charger body 1 and a data cable 2. A protective shell 3 is fitted onto the charger body 1. One end of the protective shell 3 near the plug is open, and the other end is provided with an extension shell 4. The interface of the data cable 2 is located inside the extension shell 4. A rotating wheel 5 is provided on the outer wall of the extension shell 4. A threaded rod 6 is connected to the axis of the rotating wheel 5. The threaded rod 6 is rotatably connected between the extension shell 4 and the protective shell 3. A movable plate 7 is threadedly connected to the threaded rod 6. The movable plate 7 is located outside the interface of the data cable 2, and a pressure plate 8 is slidably provided on it. The pressure plate 8 is in contact with the outer wall surface of the interface of the data cable 2.

[0018] When using this device, insert the data cable 2 into the extension shell 4 and position it inside the pressure plate 8. Then, slide the pressure plate 8 so that it aligns with the edge of the data cable 2 interface. Next, rotate the rotating wheel 5, which drives the threaded rod 6 to rotate synchronously, thereby driving the moving plate 7 to move synchronously. This causes the moving plate 7 to move the pressure plate 8 against the data cable 2 interface, moving the data cable 2 interface towards the socket of the charger body 1 until the data cable 2 interface is inserted into the socket. This achieves a tight connection between the data cable 2 and the charger body 1. At the same time, through the contact relationship between the pressure plate 8 and the data cable 2 interface, the pressure plate 8 can hold the data cable 2 interface against the charger body 1, preventing the data cable 2 from falling off the charger body 1 or making poor contact. This effectively improves the stability of the connection between the data cable 2 and the charger body 1.

[0019] Specifically, in this embodiment, the movable plate 7, the extension shell 4, and the protective shell 3 are all provided with connecting slots 9. The size of the connecting slots 9 is larger than the size of the data cable 2 interface, so that when the data cable 2 is connected to the charger body 1, the interface of the data cable 2 can pass through the extension shell 4, the movable plate 7, and the protective shell 3 through each connecting slot 9, thereby realizing the connection relationship between the data cable 2 and the charger body 1.

[0020] Specifically, in this embodiment, the extension shell 4 and the protective shell 3 are connected by a limiting rod 10, and one end of the moving plate 7 is slidably connected to the limiting rod 10, so that the moving plate 7 is restricted by the limiting rod 10 when it moves, and can only move along the direction of the limiting rod 10, thereby ensuring that the moving plate 7 moves towards the charger body 1.

[0021] Specifically, in this embodiment, two pressure plates 8 are provided, symmetrically distributed on both sides of the charger body 1, and each pressure plate 8 is provided with an L-shaped push rod 11, the top of which is located on the outside of the extension shell 4. When the position of the pressure plate 8 needs to be adjusted, the user can control the movement of the pressure plate 8 by pushing the L-shaped push rod 11, so that the pressure plate 8 can contact the interface of the data cable 2.

[0022] Specifically, in this embodiment, the extension shell 4 has two moving slots 12, and each of the two L-shaped push rods 11 is provided with a connecting shaft 13. The connecting shaft 13 is slidably adapted to the moving slot 12, so that the L-shaped push rod 11 can be slidably connected to the moving slot 12 through the connecting shaft 13, thereby achieving the purpose of adjusting the position of the pressure plate 8 through the L-shaped push rod 11.

[0023] Specifically, in this embodiment, the lengths of both connecting shafts 13 are greater than the distance from the bottom wall of the top of the L-shaped push rod 11 to the bottom of the moving groove 12. This difference in spacing allows for a certain range of motion when the moving plate 7 drives the pressure plate 8 to move up and down, enabling the moving plate 7 to drive the pressure plate 8 to move up and down within this range.

[0024] Specifically, in this embodiment, a silicone layer is provided inside the protective shell 3. This silicone layer provides cushioning when the charger is dropped, reducing the risk of damage and offering a degree of protection to extend the charger's lifespan.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
