Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolytic capacitors, and particularly relates to a surface-mounted aluminum electrolytic capacitor. Background Technique

[0002] For surface-mounted aluminum electrolytic capacitors, the material used for the cathode is electrolyte, which is divided into two categories: non-polar and polar. This is also the most common and widely used capacitor. Surface-mounted capacitors are more expensive than plug-in capacitors both in terms of the components selected and the production process cost.

[0003] The utility model patent with the publication number of CN 216528461 U discloses a new type of surface-mounted aluminum electrolytic capacitor, belonging to the technical field of capacitors. It includes a capacitor body, and a bottom plate is arranged at the bottom of the capacitor body, and a protection and stabilization device is arranged at the bottom of the bottom plate. For this new type of surface-mounted aluminum electrolytic capacitor, by setting the protection and stabilization device, the cylindrical block is inserted into the circular hole, and then the threaded block is rotated into the threaded hole, so that the first stop block and the second stop block fix the cylindrical block in the circular hole, thereby fixing the mounting plate on the circuit board to the bottom plate. At this time, through the action of the clamping block and the first round hole, the bottom plate and the mounting plate are firmly fixed. When encountering bumps or external forces, the bottom plate and the mounting plate can be firmly fixed. When the impact force is too large and causes the clamping block to separate from the first round hole, at this time, under the action of the first spring, the impact force can be buffered to prevent the bottom plate from separating from the mounting plate.

[0004] However, there are still some disadvantages in the actual use of the above device. The most obvious one is that the fixing device set on it requires too many operation steps during use, and when the capacitor is small, it may lead to greater operation difficulty and possible operation mistakes.

[0005] Therefore, it is very necessary to invent a surface-mounted aluminum electrolytic capacitor to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a surface-mounted aluminum electrolytic capacitor to solve the problems put forward in the above background technique.

[0007] To achieve the above purpose, the utility model provides the following technical scheme: A surface-mounted aluminum electrolytic capacitor includes a fixed base, a capacitor is rotatably connected inside the fixed base, a clamping component is arranged outside the capacitor, a rebounding component is arranged inside the fixed base, a shifting component is arranged inside the fixed base, and a fixing component is arranged inside the fixed base.

[0008] Preferably, the clamping component includes two fixed columns fixedly connected to the outside of the capacitor, a chute is opened inside the fixed base, and four first springs are fixedly connected inside the chute.

[0009] Preferably, the resilient component includes a first spring fixedly connected to the outside of the limiting plate. The end of the first spring is fixedly connected with a push plate, and the push plate is slidably connected to the inside of the chute.

[0010] Preferably, the shifting component includes a rotating shaft fixedly connected to the inside of the fixed base. A shifting rod is rotatably connected to the outside of the rotating shaft. The shifting rod penetrates through the fixed base and is slidably connected to the fixed base. A second spring is fixedly connected to the bottom of the outside of the shifting rod, and the end of the second spring is fixedly connected to the inside of the fixed base.

[0011] Preferably, the fixing component includes two fixing screws threadedly connected to the inside of the fixed base.

[0012] Preferably, a connection port is provided inside the fixed base, and the bottom of the capacitor is flush with the bottom of the fixed base.

[0013] Technical effects and advantages of the present utility model:

[0014] In the present utility model, by pressing the shifting rod, the shifting rod is rotated, so that the bottom of the shifting rod enters the inside of the fixed base. Then, the capacitor is rotated counterclockwise, so that the fixing post abuts against the push plate. Then, it is squeezed by the first spring. Then, the shifting rod is released, so that the shifting rod returns to its original position under the action of the second spring. Then, the capacitor is released, so that the second spring drives the push plate to push the fixing post to abut against the bottom of the shifting rod, thereby completing the fixing of the capacitor, making the installation of the capacitor more convenient and making it more convenient to replace the capacitor.
