Description

Technical Field

[0001] The utility model relates to the technical field of switching power supplies, in particular to a switching power supply with good waterproof effect. Background Art

[0002] A switching power supply is a high-frequency electric energy conversion device that uses modern power electronics technology to maintain a stable output voltage by controlling the on-off time ratio of the switch tube. There are many types of switching power supplies, and a power adapter is one of them. It is a device that converts alternating current into direct current suitable for electronic equipment.

[0003] One end of the power adapter is inserted into the corresponding device through a wire, and the other end is inserted into the socket through a power connector to provide power support. When using a portable power adapter, in order to improve its portability, the power plug is generally unplugged. At this time, the slot opened on the side of the adapter will be exposed. When the adapter is carried outdoors in rainy weather, rainwater from outside can easily enter the three-prong slot, causing the power adapter to short-circuit and be damaged. To this end, we propose a switching power supply with good waterproof effect to solve the above problem. Utility Model Content

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 , a switching power supply with good waterproof effect, including a power adapter 1, a slot 2 is opened on one side of the power adapter 1, and a power connector 3 is inserted into the slot 2, the side wall of the power adapter 1 is symmetrically opened with slides 4, and sliders 5 are inserted into the inside of the slides 4, and the sides of the sliders 5 away from each other are connected to the inner wall of the slide 4 by limit springs 6. The opening of the slide 4 can meet the lateral movement requirement of the slider 5, and the specific elastic characteristics of the limit spring 6 can ensure that the waterproof plate 7 reliably covers the slot 2, the side of the slider 5 is connected to the waterproof plate 7, and the combined area of ​​the two groups of waterproof plates 7 is larger than the opening area of ​​the slot 2, and the other side of the power adapter 1 is connected to a connecting wire 13, one end of the connecting wire 13 is fixedly connected to the side of the power adapter 1, and the other end of the connecting wire 13 is inserted into the reserved slot of the electronic device. By setting the connecting wire 13, the power adapter 1 and the electronic device can be connected.

[0023] Further, refer to Figure 2 and Figure 3 It can be seen that the side of the waterproof board 7 is connected with a linkage block 10, and the linkage block 10 is set as a columnar structure. The linkage block 10 set through the columnar structure can facilitate the staff to push the linkage block 10 horizontally and drive the two groups of waterproof boards 7 to move away from each other quickly, thereby effectively improving the convenience of using this device.

[0024] Further, refer to Figure 3 It can be seen that a limiting groove 14 is provided inside the power connector 3 to match the linkage block 10, and the inner wall of the limiting groove 14 and the outer wall of the linkage block 10 are tightly fitted. The limiting groove 14 opened at the end of the power connector 3 can preliminarily ensure the tightness of the power connector 3 when it is plugged into the slot 2.

[0025] Further, refer to Figure 3 and Figure 4 It can be seen that a connecting ring 11 is connected to the outside of the linkage block 10, and the connecting ring 11 is set to rubber material. By using multiple groups of connecting rings 11 set with rubber material, the friction force when the linkage block 10 is inserted into the limiting groove 14 can be effectively improved, thereby further ensuring the tightness of the power connector 3 during the plugging process.

[0026] Further, refer to Figure 3It can be seen that a threaded rod 12 is connected to the other side of the linkage block 10, and a threaded groove that is compatible with the threaded rod 12 is opened inside the waterproof plate 7. When in use, the threads of the threaded rod 12 and the waterproof plate 7 are matched, which makes it easy for the staff to remove the damaged linkage block 10, and at the same time can effectively reduce the floor space occupied by the device when it is packaged.

[0027] Further, refer to Figure 2 and Figure 3 It can be seen that a strip groove is provided on the inner side of the waterproof plate 7, and a guide bar 9 is inserted inside the strip groove. The guide bar 9 is fixedly connected to the side of the power adapter 1. Through the mutual cooperation of the strip groove and the guide bar 9, the waterproof plate 7 can be guided laterally to ensure the stable sliding of the waterproof plate 7, thereby effectively preventing the limit spring 6 from being skewed, thereby ensuring the service life of the limit spring 6.

[0028] Further, refer to Figure 2 It can be seen that a buffer pad 8 is glued to the side where the waterproof boards 7 are close to each other, and the length of the buffer pad 8 is adapted to the length of the waterproof boards 7. When the power connector 3 is pulled out of the slot 2, the two sets of waterproof boards 7 are automatically reset by the elastic force of the limit spring 6. At this time, the buffer pad 8 made of rubber material can effectively prevent the two sets of waterproof boards 7 from hard collision, thereby protecting the two sets of waterproof boards 7.

[0029] Working principle: When the present invention is in use, the staff can first pull the linkage block 10, thereby driving the waterproof plate 7 to move horizontally, so that the two sets of waterproof plates 7 are separated from each other and the slot 2 is opened. At this time, the user can insert the power connector 3 into the slot 2. When the power connector 3 is inserted into the slot 2, the limiting groove 14 opened inside it is able to be sleeved on the outside of the linkage block 10, and cooperate with the connecting ring 11 connected to the outside of the linkage block 10, which can effectively ensure the tightness of the power connector 3 inserted into the slot 2. Then the staff can insert the other end of the power connector 3 into the socket and insert the connector connected to the end of the connecting wire 13 into the corresponding electronic device to realize the normal use of the power adapter 1.

[0030] When use is completed, the staff will pull out the power connector 3 from the inside of the slot 2. At this time, the two sets of waterproof plates 7 are able to move closer to each other through the elastic force of the limit spring 6 to achieve covering protection for the slot 2, which can effectively prevent rainwater or other water stains from entering the slot 2, and effectively ensure the service life of the power adapter 1. The above is the entire working principle of the present invention.

[0031] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated on.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principles of the present invention should be considered as equivalent replacement methods and are included in the scope of protection of the present invention.
