Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, specifically to a flexible capacitor pin connection device. Background Technology

[0002] A capacitor is an electronic component that stores electrical energy. It consists of two conductors (plates) close to each other and an insulating medium in between. Its core function is to store charge and realize energy conversion and transfer in a circuit. Its working principle is based on electric field energy storage: when a voltage is applied across its terminals, the plates will accumulate equal amounts of opposite charges, forming an electric field to store electrical energy; after the power is turned off, the charge can be retained and needs to be released through a discharge circuit. Capacitors are key components that ensure the stable operation of circuits. From the voltage regulator modules of smartphones to the giant reactive power compensation devices of the power grid, capacitors maintain the energy order of electronic systems with a response speed of milliseconds, and can be called an indispensable "power buffer" in modern circuits. Severe vibrations occur during the operation or transportation of equipment such as automobiles and industrial machinery. Traditional rigid capacitor pins are prone to stress fatigue due to vibration impact and thermal expansion and contraction, causing relative displacement between the capacitor and the circuit. This can lead to pin breakage or poor contact due to rigid stress. Therefore, a flexible capacitor pin connection device is proposed to address the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise.

[0016] Please see Figures 1-7 This utility model provides a technical solution: A flexible capacitor pin connection device includes a lower fixed base 1 and an upper capacitor body 2. The bottom of the capacitor body 2 is provided with pin posts 3, and the bottom of the pin posts 3 is provided with a connecting component 4. The top of the fixed base 1 is symmetrically and fixedly connected with a connecting sleeve 5 with a top opening. The inner cavity of the connecting sleeve 5 is provided with an elastic component 6, and the top of the connecting sleeve 5 is provided with a limiting component 7. The elastic component 6 includes a conical spring 61. The larger bottom end of the conical spring 61 is fixedly welded with a first conductive sheet 62, and the smaller top end of the conical spring 61 is fixedly welded with a second conductive sheet 63. Both the first conductive sheet 62 and the second conductive sheet 63 are adapted to the interior of the connecting sleeve 5. The first conductive sheet 62 is fixedly welded to the bottom of the inner cavity of the connecting sleeve 5, and the second conductive sheet 63 is longitudinally slidably connected to the inner wall of the connecting sleeve 5. A conical contact head 64 is provided above the second conductive sheet 63. The connecting sleeve 5 and the pin posts 3 are coaxially aligned, and the conical contact head 64 is coaxially aligned with the connecting sleeve 5.

[0017] As a further implementation of this solution, a connecting handle 65 is fixedly welded to the bottom center of the tapered contact head 64, and the bottom end of the connecting handle 65 is fixedly welded to the top center of the second conductive sheet 63. It should be noted that the conical spring 61 of the elastic component 6 adopts a conical design instead of a traditional cylindrical spring. This structure makes the spring more evenly compressed in the longitudinal direction, effectively reducing lateral bending and ensuring the stability of the elastic buffering process. The first conductive plate 62 is fixedly welded to the bottom of the inner cavity of the connecting sleeve 5, which not only provides a stable bottom support for the conical spring 61, but also serves as the basic node of the conductive path, ensuring the reliability of current conduction. The second conductive plate 63 is longitudinally slidably connected to the inner wall of the connecting sleeve 5, and its top is fixedly welded to the conical contact head 64 through the connecting handle 65, forming an integrated elastic conductive structure of "spring-conductive plate-contact head". When the pin post 3 is inserted, the conical contact head 64 is pressed and pushes the second conductive plate 63 to compress the conical spring 61. The spring's rebound force ensures that the conical contact head 64 is always in close contact with the contact groove 43, significantly reducing contact resistance and improving conductivity. As a further implementation of this solution, the connecting component 4 includes a connecting disk 41, which is sleeved and fixed to the outer bottom of the pin post 3. A contact sleeve 42 is provided below the connecting disk 41, which is sleeved and fixed to the bottom end of the pin post 3. A contact groove 43 is provided at the bottom of the contact sleeve 42. The contact groove 43 is cone-shaped and is adapted to the cone-shaped contact head 64. It should be noted that the connecting component 4, as the key structure for docking the pin post 3 and the elastic component 6, has ingenious design details. The connecting plate 41 is sleeved and fixed on the bottom of the outer side of the pin post 3. When the pin post 3 is inserted into the connecting sleeve 5, the connecting plate 41 will abut against the top of the connecting sleeve 5 to form a mechanical limit, preventing the pin from being over-inserted and causing damage to the elastic component 6, thus playing a protective role. The contact sleeve 42 is fixed to the bottom of the pin post 3, and the conical contact groove 43 opened at its bottom is precisely matched with the conical contact head 64. This conical mating structure has an automatic centering function. Even if there is a slight radial deviation in the pin post 3, it can achieve a tight fit through the guiding effect of the conical surface, ensuring a stable contact area and effectively dealing with the positional displacement problem caused by installation or vibration. As a further implementation of this solution, the limiting component 7 includes two rotating half-rings 71. The two rotating half-rings 71 are symmetrically hinged to the top two sides of the connecting sleeve 5 through a hinge axis. The inner arc surface of the rotating half-rings 71 is fixedly connected to the limiting arc plate 72. The two rotating half-rings 71 are half of the top of the connecting sleeve 5. When they rotate and merge, they are adapted to the top of the connecting sleeve 5. The end of the limiting arc plate 72 is flush with the end of the rotating half-rings 71. When they rotate and merge, the ends of the two limiting arc plates 72 fit together. The ends of the two rotating half-rings 71 are provided with magnetic suction grooves 73. The magnetic suction groove 73 at the end of one rotating half-ring 71 is embedded with a first magnetic suction piece 74. The magnetic suction groove 73 at the end of the other rotating half-ring 71 is embedded with a second magnetic suction piece 75 that is set with a magnetic pole opposite to that of the first magnetic suction piece 74. It should be noted that the limiting component 7 provides a reliable mechanical fixation guarantee for the overall connection. The two rotating semi-rings 71 are symmetrically hinged to the top two sides of the connecting sleeve 5 through the hinge axis. The limiting arc plate 72 on its inner side can block and limit the connecting plate 41 after rotation and merging, forming a radial constraint to prevent the pin post 3 from shaking or falling off in the equipment operation or vibration environment. The magnetic groove 73 at the end of the rotating semi-ring 71 is respectively embedded with the first magnetic absorbing piece 74 and the second magnetic absorbing piece 75 with opposite magnetic poles. When merging, they are automatically attracted and fixed by magnetic force, without the need for additional fasteners. During installation, the semi-rings can be fixed by simply flipping them over. During disassembly, they can be separated by gently prying them open, which greatly simplifies the installation and disassembly process.

[0018] Workflow: The complete workflow of this solution revolves around four stages: installation and fixing, conductive connection, operational support, and disassembly and maintenance. Each component works collaboratively throughout the process to ensure stable and reliable connections. During the installation preparation stage, the fixing base 1 is first fixed to the circuit board or equipment base through the preset installation structure to ensure that the connecting sleeve 5 is in a stable vertical state. At this time, the elastic component 6 is in a naturally extended state, the conical spring 61 is not compressed, the second conductive plate 63 is located at the upper part of the inner cavity of the connecting sleeve 5, the conical contact head 64 extends upward, and the two rotating half rings 71 of the limiting component 7 are in an open state, that is, they are rotated outward around the hinge axis, so that the top opening of the connecting sleeve 5 is fully exposed, which is ready for the insertion of the pin post 3. The installation and docking stage is the core process. The operator holds the capacitor body 2 and aligns the bottom pin post 3 with the axis of the connecting sleeve 5, and slowly inserts it downwards. When the contact groove 43 at the bottom of the contact sleeve 42 contacts the conical contact head 64, the operator continues to apply downward pressure. The conical contact head 64 is compressed and pushes the second conductive plate 63 to slide downwards along the inner wall of the connecting sleeve 5. At the same time, the conical spring 61 is compressed. As the insertion depth increases, the connecting plate 41 gradually approaches the top of the connecting sleeve 5 until the bottom surface of the connecting plate 41 contacts the top edge of the connecting sleeve 5. At this time, the pin post 3 reaches the preset installation depth, and the conical spring 61 is in a moderately compressed state, storing elastic potential energy. After insertion, the process enters the fixing and locking stage. The operator flips the two rotating half-rings 71 inside the hinge axis. The two mutually fitting limiting arc plates 72 will block and limit the connecting plate 41. When the two rotating half-rings 71 are completely merged, the first magnetic suction piece 74 and the second magnetic suction piece 75 at the end attract each other through opposite magnetic poles to achieve automatic locking. The limiting component 7 forms a complete ring constraint structure, which stably restricts the pin post 3 in the connecting sleeve 5 to prevent axial movement and radial shaking. During operation, the elastic component 6 plays a crucial role. The rebound force of the conical spring 61 continuously pushes the second conductive plate 63 upward, ensuring that the conical contact head 64 is always tightly fitted against the inner wall of the contact groove 43, guaranteeing reliable and stable conductive contact between the two. The current is transmitted through the pin post 3 to the contact sleeve 42, and then through the contact surface between the contact groove 43 and the conical contact head 64 to the second conductive plate 63. It is then transmitted through the conical spring 61 and the first conductive plate 62 to the external circuit at the bottom of the connecting sleeve 5, forming a complete conductive path. When the equipment vibrates or the temperature changes, causing thermal expansion and contraction, the elastic extension and contraction of the conical spring 61 can automatically compensate for small displacements, maintain stable contact pressure, and avoid poor contact. If disassembly and maintenance are required, the process is reversed. The operator manually pries open the two rotating half-rings 71 to overcome the magnetic attraction of the first magnetic absorbing plate 74 and the second magnetic absorbing plate 75, so that the limiting component 7 opens. Under the action of the rebound force of the conical spring 61, the second conductive plate 63 drives the conical contact head 64 to return to its original position, pushing the contact sleeve 42 and the lead post 3 to pop up a certain distance, so that the operator can pull out the capacitor body 2 as a whole, completing the disassembly operation. The elastic component 6 returns to its natural extended state, waiting for the next installation and use.
