Description

Technical Field

[0001] This utility model belongs to the field of capacitor fixing technology, and particularly relates to portable fixed capacitors. Background Technology

[0002] A capacitor is a passive electronic component used to store electrical energy and plays a variety of roles in a circuit. It consists of at least two conductors (usually called electrodes) separated by a layer of insulating material (also called a dielectric). When a voltage is applied to a capacitor, charge accumulates between the two electrodes, creating an electric field and storing energy.

[0003] Traditional large-volume capacitors suffer from poor stability and are prone to tipping over when mounted on circuit boards or devices. While existing mounting designs improve stability, they increase the cost and weight of the device and make installation and disassembly inconvenient. Utility Model Content

[0004] This utility model addresses the problem of poor stability and easy tipping of large-volume capacitors when mounted on circuit boards or devices in the prior art, and proposes the following technical solution:

[0005] A portable fixed capacitor includes: a capacitor body and a mounting base. The mounting base is fixedly connected to an external circuit board or device. A stabilizing component is provided between the mounting base and the capacitor body. The stabilizing component includes a push ring and a driving component. Multiple support blocks are circumferentially arranged on the inner side of the push ring. One end of each support block is rotatably inserted into the interior of the mounting base. A torsion spring is provided between the insertion point of the support block and the mounting base. The other end of the support block is used to support the capacitor body.

[0006] As a preferred embodiment of the above technical solution, the driving component includes a lead screw and a plurality of movable sliders. The movable sliders are fixedly connected to the push ring. One of the movable sliders is threaded onto the surface of the lead screw, and the other movable sliders are movably inserted into the middle of a limiting rod that is fixedly connected to the mounting base.

[0007] As a preferred embodiment of the above technical solution, the middle part of the support block is curved, and the bottom of the support block is inclined outward from the mounting base.

[0008] As a preferred embodiment of the above technical solution, an elastic block is provided at the end of the support block, and the elastic block is in contact with the capacitor body.

[0009] The beneficial effects of this utility model are as follows:

[0010] Driven by the driving component, the upward movement of the pushing ring pushes multiple support blocks to deflect. The multiple support blocks simultaneously retract inward to support the capacitor body, increasing the stability of the capacitor and preventing the capacitor body from tipping over. At the same time, by adjusting the position of the pushing ring, the deflection angle of the support blocks can be controlled, making it applicable to capacitor bodies of different diameters, thus increasing its applicability.

[0015] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0016] Example

[0017] Figures 1-3 A portable fixed capacitor includes a capacitor body 10 and a mounting base 20. The mounting base 20 is fixedly connected to an external circuit board or device. A stabilizing component is provided between the mounting base 20 and the capacitor body 10. The stabilizing component includes a push ring 31 and a driving component. The push ring 31 is coaxially arranged with the capacitor body 10. A plurality of support blocks 32 are circumferentially arranged on the inner side of the push ring 31. One end of the support block 32 is rotatably inserted into the interior of the mounting base 20. A torsion spring is provided between the insertion point of the support block 32 and the mounting base 20. The two ends of the torsion spring are fixedly connected to the support block 32 and the mounting base 20, respectively. The other end of the support block 32 is used to support the capacitor body 10.

[0018] The support block 32 is curved in the middle, and the bottom of the support block 32 is inclined to the outside of the capacitor body 10 between the mounting base 20 and the support block 32.

[0019] By moving the push ring 31 upward, multiple support blocks 32 are pushed and deflected. The multiple support blocks 32 simultaneously retract inward to support the capacitor body 10, increasing the stability of the capacitor and preventing the capacitor body from tipping over. At the same time, by adjusting the position of the push ring 31, the deflection angle of the support blocks 32 can be controlled, which can be used for capacitor bodies 10 of different diameters, making it more versatile.

[0020] Figures 1-3 In the drive unit, the drive unit includes a lead screw 41 and a plurality of movable sliders 42. The end of the lead screw 41 is provided with a knob. The movable sliders 42 are fixedly connected to the push ring 31. One of the movable sliders 42 is threaded onto the surface of the lead screw 41. The other movable sliders 42 are movably inserted into the middle of a limiting rod 43 that is fixedly connected to the mounting base 20.

[0021] The set driving component can stably push the push ring 31 to move. After the push ring 31 moves, it can be fixed in a certain position to prevent the push ring 31 from dislodging and causing the stabilizing component to fail to support the capacitor body 10.

[0022] Figures 1-3 In the middle, an elastic block 33 is provided at the end of the support block 32, and the elastic block 33 is in contact with the capacitor body 10.

[0023] The elastic block 33 can make elastic contact with the capacitor body 10. The deformed elastic block 33 can increase the contact area with the capacitor body 10, effectively increasing the friction with the capacitor body 10, thereby making the support and restriction of the capacitor body 10 more stable.

[0024] Working principle: After the capacitor body 10 is installed and fixed, the limiting rod 43 restricts the corresponding movable slider 42. By rotating the screw 41 with the knob, the corresponding movable slider 42 moves upward, and the pushing ring 31 moves upward to push the support block 32. Because the middle part of the support block 32 is curved and the bottom of the support block 32 is inclined to the outside of the capacitor body 10 between the support block 32 and the mounting base 20, the support block 32 is pushed and deflected. The torsion spring is twisted and deformed accordingly. The elastic block 33 contacts the capacitor body 10 and deforms. Multiple support blocks 32 simultaneously retract inward to restrict the capacitor body 10. The deflection angle of the support block 32 is controlled by adjusting the position of the pushing ring 31, so that it can be used for capacitor bodies 10 of different diameters.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
