Description

Technical Field

[0001] This utility model relates to the field of power adapters, and in particular to a power adapter that prevents interface breakage. Background Technology

[0002] As a core power supply component for electronic devices, power adapters are widely used in various electronic devices such as computers, mobile phones, and home appliances. Their main function is to convert AC power into stable voltage and current required by electronic devices, and to transmit power through the connection between the plug and the device interface.

[0003] With the increasing popularity of electronic devices and the diversification of usage scenarios, power adapters are being used more and more frequently. As a key connection point for power transmission, the structural stability of the plug-to-body interface directly affects the lifespan and safety of the power adapter.

[0004] A search revealed Chinese Patent Publication No. CN221227356U, which discloses a power adapter designed to prevent interface breakage. The adapter body includes a slot at the center of its front side, a contact plate within the slot, and a plug outside the contact plate. A connecting wire is fixedly connected to the rear side of the adapter body. A fixing seat is fixedly connected to the upper front side of the adapter body. A first sliding groove extends through the fixing seat, and a driving component is housed within the first sliding groove. Two fixing clamps are connected to the driving component, and protective components are provided on opposite sides of each of the two fixing clamps. A heat dissipation component is located inside the right side of the adapter body. This invention utilizes a bidirectional threaded rod, a movable seat, fixing clamps, a mounting groove, protective clamps, a first sliding groove, and a limiting block to work together to secure the plug, preventing loosening and thus preventing interface breakage.

[0005] Although the device has been improved to some extent, it can fix the plug, improve the stability of the connection, and protect the interface to a certain degree. However, in actual use, if the power cord of the plug is pulled by a strong external force, such as if a passerby accidentally trips over it, the pulling force will be transmitted to the plug, which can still easily lead to breakage and damage at the plug and the interface of the device. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a power adapter that prevents interface breakage, aiming to improve the problem in the prior art where the power adapter is subjected to strong external force when the plug and wire are pulled, and the force is transmitted to the plug, which can easily cause the interface between the plug and the device to break and be damaged.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a power adapter for preventing interface breakage, comprising a body, a connecting wire fixedly installed at the rear end of the body, a mounting plate fixedly installed on the front surface of the body by screws, a plug inserted into the front end of the body, and a protective component provided at the front end of the mounting plate; The protective assembly includes a fixing plate, the rear surface of which abuts against the front surface of a mounting plate. A slot is formed through the inner surface of the fixing plate, and a insert plate is inserted into the inner wall of the slot. Connecting blocks are fixedly connected to both the upper and lower ends of the rear surface of the insert plate. A limiting block is fixedly connected to the side of the connecting block away from the center of the fixing plate. A limiting groove is formed on the front surface of the mounting plate. Push plates are slidably connected through the left and right sides of the mounting plate. An anti-loosening component is provided at the front of the fixing plate.

[0008] As a further description of the above technical solution: The anti-loosening component includes a bidirectional threaded rod that passes through and is rotatably connected to the inner wall of the fixed plate. Handwheels are fixedly connected to both ends of the bidirectional threaded rod. A connecting plate is threadedly connected to the outer wall of the bidirectional threaded rod, and a clamping plate is fixedly connected to the bottom end of the connecting plate.

[0009] As a further description of the above technical solution: The insert plate and slot are provided in two sets. The two sets of insert plates and slots are symmetrically distributed on the left and right with the center line of the fixing plate as the axis. The front end of the insert plate is shaped like a protruding plate, and the rear surface of the protruding plate is in contact with the front surface of the fixing plate.

[0010] As a further description of the above technical solution: The slot is constructed as a U-shaped structure with its opening facing away from the center of the fixing plate.

[0011] As a further description of the above technical solution: The connecting block is inserted into the inner wall of the limiting groove, and the limiting block is engaged with the inner wall of the limiting groove. The limiting block consists of two parts: the half of the limiting block near the connecting block is a vertical plate oriented front to back, and the half of the limiting block away from the connecting block is a shape that gradually tilts towards the connecting block from front to back.

[0012] As a further description of the above technical solution: The push plate is configured in an I-shape.

[0013] As a further description of the above technical solution: The connecting plate is L-shaped and is slidably connected to the front surface of the fixed plate.

[0014] As a further description of the above technical solution: The connecting plate and clamping plate are each provided in two sets. The two sets of connecting plates and clamping plates are symmetrically distributed about the center line of the bidirectional threaded rod as the axis of symmetry. The two sets of clamping plates jointly clamp one end of the plug, and the front opening size of the clamping plate is larger than its rear opening size.

[0015] This utility model has the following beneficial effects: 1. In this utility model, overload protection at the plug is achieved through a protective component. The limit block made of elastic metal can stably fix the fixing plate and the mounting plate by snapping when the plug wire is subjected to normal external force, thus preventing the plug from loosening. When the tensile force exceeds the deformation range of the limit block, the limit block bends in the opposite direction to release the limit, thus preventing the plug from breaking at the interface with the device due to strong tensile force.

[0016] 2. In this utility model, the anti-loosening component, together with the protective component, improves the stability of the interface. Rotating the handwheel drives the bidirectional threaded rod to rotate, which in turn drives the clamping plate to hold the plug, ensuring the stability of the plug connection and reducing shaking and wear during use. At the same time, the mounting plate is adapted to different bodies through screws, ensuring the practicality of the device. Attached Figure Description

[0019] 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.

[0020] Reference Figures 1-2 This utility model provides an embodiment of a power adapter that prevents interface breakage. It includes a body 1, which is the main structure of the power adapter and contains various components. The body 1 is existing technology and can be implemented by those skilled in the art; therefore, it will not be described in detail here. A connecting wire 2 is fixedly installed at the rear end of the body 1 for transmitting electrical energy, delivering the converted power from the body 1 to the target device; this is a key channel for power transmission. A mounting plate 3 is fixedly installed on the front surface of the body 1 with screws. The mounting plate 3 can be flexibly installed and removed, and can be fixed to the outer shell of different models of the body 1 using screws. A plug 4 is inserted into the front end of the body 1. The plug 4 is the connection interface between the body 1 and external devices for transmitting electrical energy. Its connection stability directly affects whether the interface is prone to breakage and is also the object of protection in this technical solution. A protective component 6 is provided at the front end of the mounting plate 3 to prevent excessive external force from acting on the plug 4, causing breakage.

[0021] Reference Figures 3-5The protective component 6 includes a fixing plate 67, the rear surface of which abuts against the front surface of the mounting plate 3. A slot 62 is formed through the inner surface of the fixing plate 67, and a plate 61 is inserted into the inner wall of the slot 62. The contact surfaces of the plate 61 and the slot 62 are fitted together to prevent loosening. Two sets of plates 61 and slots 62 are provided, symmetrically distributed about the center line of the fixing plate 67. This allows for limiting the fixing plate 67 from both sides, ensuring its stability in four directions (up, down, left, and right). The front end of the insert plate 61 is a raised plate, and the rear surface of the raised plate fits against the front surface of the fixing plate 67. This, in conjunction with the mounting plate 3, ensures the stability of the fixing plate 67 in the front-back direction. The slot 62 is a U-shaped structure with its opening facing away from the center of the fixing plate 67. Connecting blocks 63 are fixedly connected to both the upper and lower ends of the rear surface of the insert plate 61. A limiting block 64 is fixedly connected to the side of the connecting block 63 away from the center of the fixing plate 67. Both the connecting block 63 and the limiting block 64 penetrate the slot 62. The limiting block 64 is made of elastic metal. The mounting plate 3... A limiting groove 65 is formed on the front surface. A connecting block 63 is inserted into the inner wall of the limiting groove 65, and a limiting block 64 is engaged with the inner wall of the limiting groove 65 to form a limiting position. The limiting block 64 consists of two parts: the half of the limiting block 64 near the connecting block 63 is shaped like a vertical plate facing forward and backward, and the half of the limiting block 64 away from the connecting block 63 is shaped like a plate that gradually slopes towards the connecting block 63 from front to back. When the limiting block 64 and the limiting groove 65 are inserted, the sloped section will be compressed and deformed to contact and block the connection. When the limiting block 64 and the limiting groove 65 are fully inserted, the limiting position is achieved. The locking block 64 will achieve a snap-fit ​​due to its own elastic recovery. When the forward pulling force is large and exceeds the deformation range of the locking block 64, the locking block 64 will be pulled and bent in the opposite direction to release the limit and avoid breakage at the plug 4 interface. The left and right sides of the mounting plate 3 are both slidably connected with push plates 66. The front of the fixing plate 67 is provided with an anti-loosening component 5. The push plate 66 is set in an I-shape and is flush with the locking block 64. When the push plate 66 is pushed towards the middle of the mounting plate 3, it will squeeze the locking block 64, causing the locking block 64 to elastically deform and release the obstruction.

[0022] Reference Figures 1-3The anti-loosening component 5 includes a bidirectional threaded rod 52, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The bidirectional threaded rod 52 is rotatably connected to the inner wall of the fixed plate 67. Handwheels 51 are fixedly connected to both ends of the bidirectional threaded rod 52. The handwheels 51 are easy to rotate and have anti-slip texture on their surface. A connecting plate 53 is threadedly connected to the outer wall of the bidirectional threaded rod 52. The connecting plate 53 is L-shaped and is slidably connected to the front surface of the fixed plate 67. A clamping plate 54 is fixedly connected to the bottom end of the connecting plate 53. There are two sets of connecting plates 53 and clamping plates 54. The two sets of connecting plates 53 and clamping plates 54 are symmetrically distributed about the center line of the bidirectional threaded rod 52. The two sets of clamping plates 54 clamp one end of the plug 4 together, which can fix one end of the plug 4. The front opening size of the clamping plate 54 is larger than its rear opening size to prevent it from falling off.

[0023] Working principle: When using this device, first use screws to install the mounting plate 3 in a suitable position on the outer shell of the device body 1, and then insert the insert plate 61 of the protective component 6 into the U-shaped slot 62 of the fixing plate 67, so that the connecting block 63 and the limiting block 64 at the rear end of the insert plate 61 are aligned with the limiting groove 65 of the mounting plate 3 and inserted.

[0024] The inclined section of the limiting block 64 is squeezed and deformed during insertion. After full insertion, it elastically recovers and locks into the inner wall of the limiting groove 65. With the cooperation of the front protrusion of the insertion plate 61 and the fixing plate 67, the fixing plate 67 is fixed. Then, the plug 4 is inserted into the front end of the body 1. By turning the handwheel 51, the bidirectional threaded rod 52 is rotated. The bidirectional threaded rod 52 drives the two sets of L-shaped connecting plates 53 to slide towards each other along the front surface of the fixing plate 67. This causes the two sets of clamping plates 54 to move closer to each other and clamp one end of the plug 4. The design of the clamping plate 54 with a large opening at the front end and a small opening at the rear end not only facilitates the smooth insertion of the plug 4, but also achieves tight clamping, preventing the plug 4 from loosening or shaking due to slight external force during use, and ensuring the stability of the connection.

[0025] During use, if the wire connecting plug 4 is affected by external force, plug 4 will be pulled. The pulling force will be transmitted to the limiting block 64 through plug 4, anti-loosening component 5, fixing plate 67, plug plate 61, and connecting block 63. When the pulling force exceeds the deformation range of the limiting block 64, the limiting block 64 will bend in the opposite direction to release the locking limit, thereby allowing plug 4 to fall off and preventing the interface from breaking.

[0026] During disassembly, first rotate the handwheel 51 in the opposite direction to drive the bidirectional threaded rod 52 to rotate, which will drive the two sets of connecting plates 53 and clamping plates 54 to open and release the clamping of the plug 4. Then push the I-shaped push plate 66 towards the middle of the mounting plate 3. The push plate 66 presses the limiting block 64 to deform and disengage it, thus separating the fixing plate 67 from the mounting plate 3. The operation is convenient.

[0027] 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.
