Description

Technical Field

[0001] This utility model relates to the field of adapters, specifically a power adapter with overload protection. Background Technology

[0002] As a key component for powering electronic devices, the power adapter's technological development closely follows the evolution of the electronics industry. Early power adapters mostly used linear power supply technology, which achieved voltage conversion through transformer step-down, rectification, and filtering. Although the output was stable, it had problems such as large size, low efficiency (usually only 40%-60%), and serious heat generation. With the advancement of semiconductor technology, switching power supply technology emerged, which achieves power conversion through high-frequency switching devices, improving efficiency to 80%-95%, significantly reducing the size and weight of the adapter, and reducing energy consumption.

[0003] An existing power adapter with overload protection typically has a set of working chip boards. The working chip boards are fitted with Mylar plates and heat sinks. The working chip boards with heat sink components are then encased in a protective shell. When the device is running, the heat sink can dissipate heat and prevent the device from overloading during use, thus affecting the normal operation of the device.

[0004] However, for existing power adapters with overload protection, the working chip is encased in a heat sink and then installed in a protective case, which results in a small contact area with the air, severely affecting the heat dissipation of the working chip board and hindering the normal use of the device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a power adapter with overload protection to solve the technical problem mentioned in the background art that the existing power adapters with overload protection have poor performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a power adapter with overload protection, comprising an adapter body, a first side groove on the side of the adapter body, a second side groove inside the first side groove, and side grooves on both sides of the adapter body. Limiting holes are provided at the top and bottom of the inner wall of the first side groove, a lower protruding rod is fitted inside the limiting hole, a guide fin is fixedly installed on the top of the lower protruding rod, an inner groove is provided on the top of the guide fin, a spring is fixedly installed inside the inner groove, one end of the spring is connected to an upper protruding rod, a sliding plate is fitted inside the second side groove, a filter screen is provided inside the sliding plate, and a protruding plate is provided on one side of the sliding plate.

[0007] By adopting the above technical solution, the problem of poor performance of existing power adapters with overload protection mentioned in the background art is solved. By incorporating a partition, the working chip board is not completely flush with the adapter body, thus forming a return air cavity. Simultaneously, a first side groove is formed on the side of the adapter body, within which inclined air guide fins are movably installed. These fins guide external natural airflow into the adapter body, improving air circulation and thus dissipating heat from the working chip board. The bottom of the air guide fins has a downward convex shape. The lower protruding rod is fitted into a limiting hole opened on the inner side of the first side groove. The top of the air guide fin has a fin inner groove, and a spring is fixedly installed in the fin inner groove. One end of the spring is fixedly installed with an upper protruding rod, which is also fitted into a limiting hole opened on one side of the first side groove. When the air guide fin has a medium adhering to its surface after long-term use, by pulling the air guide fin upward, the lower protruding rod at the bottom of the air guide fin can be dislodged from the limiting hole, thereby removing the air guide fin from the first side groove and completing the replacement of the air guide fin. Moreover, the limiting hole, the lower protruding rod, and the upper protruding rod are all set as polygons, so that the air guide fin can play a role in adjusting the tilt angle, making the device more practical.

[0008] The present invention is further configured such that a connecting wire is provided at one end of the adapter body, and a connecting hole is provided at the other end of the adapter body.

[0009] Preferably, the adapter body is equipped with a connecting wire at one end and a connecting hole at the other end, so that the adapter body can achieve the desired effect.

[0010] The present invention is further configured such that a partition is fixedly installed inside the adapter body, and the working chip board is fixedly installed inside the adapter body through the partition.

[0011] Preferably, by fixing a partition block inside the adapter body, the working chip board is fixedly installed inside the adapter body through the partition block, so that a return air cavity can be formed inside the adapter body, avoiding the working chip board from being tightly attached to the adapter body, thereby affecting the normal use of the device.

[0012] The present invention is further configured such that the cross-sectional area of ​​the second side groove is greater than the cross-sectional area of ​​the first side groove, and the opening depth of the second side groove is less than the opening depth of the first side groove.

[0013] Preferably, by making the cross-sectional area of ​​the second side groove larger than that of the first side groove and the opening depth of the second side groove smaller than that of the first side groove, the skateboard can be stably installed inside the second side groove, thus preventing the skateboard from shaking after installation and affecting its performance.

[0014] The present invention is further configured such that the limiting hole is a hexagonal rod, and the lengths of the lower protrusion and the upper protrusion are both greater than the opening depth of the limiting hole.

[0015] Preferably, by setting the limiting hole as a hexagonal rod, the tilt angle of the air guide fin can be adjusted. The lengths of both the lower and upper protrusions are greater than the opening depth of the limiting hole, so as to avoid the lower protrusion being unable to be removed from the limiting hole when the air guide fin is pushed to one side due to excessive opening depth of the limiting hole.

[0016] The present invention is further configured such that the length of the lower protruding rod is less than the length of the upper protruding rod, and the air guide fins are inclined.

[0017] Preferably, by making the length of the lower protruding rod shorter than the length of the upper protruding rod and by setting the air guide fins at an angle, the air guide fins can guide the external natural wind.

[0018] The present invention is further configured such that the slide plate is fixedly installed in the second side groove by bolts, the first side groove and the side groove have the same opening depth, and the height of the convex plate is greater than the depth of the side groove.

[0019] Preferably, the slide plate is fixedly installed in the second side groove by bolts. When the internal filter of the slide plate accumulates a lot of external media after long-term use, the slide plate can be replaced by bolts. The opening depth of the first side groove and the side groove is the same, and the height of the convex plate is greater than the depth of the side groove. When the slide plate needs to be replaced, the convex plate can better push the slide plate, which can improve the practicality of the device.

[0020] The present invention is further configured such that the limiting hole is opened on the outside of the second side groove, and the bottom of the second side groove is provided with an inclined surface.

[0021] Preferably, by opening the limiting hole on the outside of the second side groove, the air guide fins are prevented from colliding with the slide plate, thereby affecting the normal use of the slide plate. The bottom of the second side groove is provided with an inclined surface to facilitate the installation of the air guide fins.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model, by comprising an adapter body, connecting wires, a partition, a working chip board, a first side groove, a second side groove, a side groove, a limiting hole, a sliding plate, a filter, a protruding plate, air guide fins, a lower protruding rod, an inner groove for the fins, a spring, and an upper protruding rod, solves the problem of poor performance of existing power adapters with overload protection mentioned in the background art. By including the partition, the working chip board is not completely flush with the adapter body, thus forming a return air cavity. Simultaneously, a first side groove is provided on the side of the adapter body, within which an inclined air guide fin is movably installed. The air guide fins act as a guide for external natural wind, allowing it to enter the adapter body and improve airflow within the adapter body, thereby dissipating heat from the working chip board. When the surface of the air guide fins becomes coated with a medium after prolonged use, the air guide fins can be pulled upwards to disengage the lower protrusion at the bottom of the air guide fin from the limiting hole, thus removing the air guide fin from the first side groove and completing the replacement of the air guide fin. Furthermore, the limiting hole, lower protrusion, and upper protrusion are all designed as polygons, allowing the air guide fins to be tilted at an adjustable angle, making the device more practical.

[0024] 2. This utility model features a first side groove, within which a second side groove is located. A slide plate, fixedly mounted with bolts, is installed within the second side groove.

The opening depth of the first side groove 5 and the side groove 7 is the same. The height of the protruding plate 11 is greater than the depth of the side groove 7. When the slide plate 9 needs to be replaced, the protruding plate 11 can better push the slide plate 9, which can improve the practicality of the device.

[0047] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 The limiting hole 8 is opened on the outside of the second side groove 6. The bottom of the second side groove 6 is provided with an inclined surface. By opening the limiting hole 8 on the outside of the second side groove 6, the air guide fin 12 is prevented from colliding with the slide plate 9, thereby affecting the normal use of the slide plate 9. The bottom of the second side groove 6 is provided with an inclined surface to facilitate the installation of the air guide fin 12.

[0048] In practical operation: the working chip board 4 is fixedly installed inside the adapter body 1 by the partition block 3. A connecting wire 2 is provided on one side of the adapter body 1. The adapter body 1 can achieve the working effect through the connecting wire 2 and the internal connection hole.
