Description
Technical Field
[0001] This utility model relates to the field of protective mechanisms, specifically a capacitor protective mechanism. Background Technology
[0002] A capacitor consists of two conductors that are close to each other and insulated from each other. These two conductors are called plates. The insulating medium between them can be air, ceramic, mica, paper, plastic film, etc. The plates are usually made of metal, such as aluminum or tantalum, so that they can store electric charge.
[0003] According to the search, a capacitor includes plates, dielectric, electrodes, and encapsulation. The encapsulation shell material can be plastic, metal, etc. Plastic shells have advantages such as good insulation, light weight, and low cost; metal shells have better electromagnetic shielding performance and mechanical strength. Through plug-in encapsulation, due to the long leads, it is easy to insert into the through holes of the circuit board for soldering. It is widely used in traditional electronic circuits. When the circuit is working, the current flows into and out of the capacitor through the leads.
[0004] The aforementioned capacitor has the following problems: The capacitor is connected to the circuit board through pins so that it can work smoothly. At the same time, the heat generated by the capacitor is dissipated through the external package. However, during production, transportation, installation and use, the capacitors may be subjected to mechanical external forces such as collision, squeezing and vibration. During transportation, if there is no proper protection, the capacitor may collide with other objects, which may damage the pins, thereby affecting the performance of the capacitor or even causing it to be damaged and unable to work properly.

[0020] 1. A capacitor protection mechanism, comprising a heat-conducting rod, a protective shell, a support plate, and a spring, wherein when the capacitor is not in use, the spring allows the leads to smoothly enter the protective shell, preventing damage to the leads, while the support plate restricts and stabilizes the capacitor.
[0021] 2. A capacitor protection mechanism, comprising a rotating shaft, a heat-conducting plate, a brake rod, a limiting block, and a heat dissipation column, allows the user to press the heat-conducting rod to move the leads out of the protective shell when the capacitor needs to be used, and simultaneously restrict the position of the capacitor by rotating the brake rod and using the limiting block. At the same time, when the heat-conducting plate comes into contact with the outer wall of the protective shell, the heat generated by the capacitor is conducted to the protective shell through the heat-conducting plate and then dissipated to the outside through the heat dissipation column.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0029] The embodiments of this utility model will be described below based on its overall structure.
[0030] A capacitor protection mechanism, such as Figure 1 - Figure 4 As shown, the device includes a capacitor 1 and pins 11. Pins 11 are fixedly mounted on the end of the capacitor 1. A heat-conducting rod 2 is fixedly mounted on the end of the capacitor 1. A rotating shaft 21 is rotatably mounted on the end of the heat-conducting rod 2. A heat-conducting plate 22 is fixedly mounted on the outer wall of the rotating shaft 21. A brake rod 23 is fixedly mounted on the outer wall of the rotating shaft 21. A protective shell 3 is slidably mounted on the outer wall of the heat-conducting rod 2. The heat generated by the capacitor 1 is guided to the heat-conducting plate 22 through the heat-conducting rod 2, and then the heat-conducting plate 22 conducts the heat to the protective shell 3. A support plate 31 is fixedly mounted on the inner wall of the protective shell 3, and a heat dissipation column 32 is fixedly mounted on the outer wall of the protective shell 3. A limiting block 4 corresponding to the heat-conducting plate 22 is fixedly mounted on the end of the protective shell 3. A spring 5 corresponding to pins 11 is installed inside the protective shell 3. The brake rod 23 presses the heat-conducting rod 2, causing the heat-conducting rod 2 to slide inside the protective shell 3, while simultaneously causing the end of the capacitor 1 to start compressing the spring 5.
[0031] Please refer to Figure 1. Figure 4 Multiple sets of heat-conducting plates 22 are arranged at equal angles on the outer wall of the rotating shaft 21. The multiple sets of heat-conducting plates 22 can smoothly conduct the heat dissipated by the capacitor 1 to the protective shell 3. The interval between the two sets of heat-conducting plates 22 corresponds to the limiting block 4. When the heat-conducting plate 22 contacts the limiting block 4, the interval between the heat-conducting plates 22 guides the heat-conducting plate 22 to slide smoothly on the outer wall of the limiting block 4.
[0032] Please see Figure 1 - Figure 4 The brake lever 23 is located on the outer wall of the rotating shaft 21 away from the capacitor 1. When the user presses the heat-conducting rod 2, it ensures that the brake lever 23 can smoothly adhere to the protective shell 3.
[0033] Please see Figure 2 - Figure 4 Multiple sets of support plates 31 are arranged at equal intervals inside the protective shell 3. Multiple sets of support plates 31 are arranged at equal angles inside the protective shell 3. Under the restriction of multiple sets of support plates 31, the capacitor 1 remains stable inside the protective shell 3, and the outer wall of the support plate 31 is in contact with the outer wall of the capacitor 1, ensuring that the support plate 31 can smoothly restrict the position of the capacitor 1.
[0034] Please see Figure 2 - Figure 4 Multiple sets of heat dissipation columns 32 are arranged at equal angles on the outer wall of the protective shell 3. The multiple sets of heat dissipation columns 32 enable the heat inside the protective shell 3 to dissipate smoothly. The protective shell 3 has a sliding groove corresponding to the pin 11, so that when the capacitor 1 slides inside the protective shell 3, the pin 11 can be smoothly moved out of the protective shell 3.
[0035] Please see Figure 2 One end of the spring 5 is in contact with the end of the capacitor 1, and the other end of the spring 5 is in contact with the inner wall of the protective shell 3, ensuring that the capacitor 1 can move smoothly inside the protective shell 3 under the action of the spring 5.
[0036] The working principle of this utility model is as follows: When the user does not use the capacitor 1, the pin 11 at the end of the capacitor 1 smoothly enters the protective shell 3 under the action of the spring 5. At this time, under the protection of the protective shell 3, the pin 11 is protected from damage. At the same time, due to the design that multiple sets of support plates 31 are in contact with the capacitor 1, the stability of the capacitor 1 in the protective shell 3 is ensured.
[0037] When the user needs to use capacitor 1, the user first presses the heat-conducting rod 2 with the brake lever 23 to make the heat-conducting rod 2 slide inside the protective shell 3. At the same time, the end of capacitor 1 starts to squeeze the spring 5. At this time, the pin 11 starts to slide inside the protective shell 3. When the heat-conducting plate 22 is in contact with the outer wall of the protective shell 3, the pin 11 slides out completely outside the protective shell 3. At this time, the user can rotate the brake lever 23 to make the heat-conducting plate 22 start to slide at the end of the heat-conducting rod 2. When the outer surface of the heat-conducting plate 22 contacts the outer wall of the limiting block 4, the capacitor 1 remains stable under the action of the spring 5. At the same time, when capacitor 1 starts to work, the heat generated by capacitor 1 is guided to the heat-conducting plate 22 through the heat-conducting rod 2, and then the heat-conducting plate 22 conducts the heat to the protective shell 3. Finally, the heat of capacitor 1 is successfully dissipated under the heat dissipation column 32.
