Description

Technical Field

[0001] The utility model belongs to the technical field of connection terminals, and particularly relates to a capacitor connection terminal. Background Art

[0002] A capacitor is a common electronic component with wide applications. It has the ability to store charge and energy and can play various roles in a circuit. Capacitors are widely used in various electronic devices, such as televisions, mobile phones, computers, etc. They are used for functions such as storing electrical energy, stabilizing voltage, filtering, coupling, and phase adjustment to ensure the normal operation of the devices.

[0003] The working process of a capacitor can be understood as a charging and discharging process. An ideal capacitor does not consume energy and thus cannot generate heat at all. However, this is only an ideal situation. Due to limitations in production processes, the capacitors we actually use are not ideal capacitors. The capacitors we actually use can be understood as being equivalent to an ideal capacitor in series with a resistor and an inductor. This also means that when a capacitor is actually working, it will definitely consume energy, but the energy it consumes is not large. Therefore, the heat generation situation of a capacitor during operation is generally not too serious. In an actual circuit, high-power triodes, integrated circuits, resistors, and transformers are the electronic components that generate more heat. In a high-temperature environment, a capacitor will face a series of challenges, including possible physical changes in the internal materials of the capacitor, such as volume changes or mass reduction due to thermal expansion and contraction, and possible wetting phenomena in the adhesive between the insulating dielectric material and the electrode, resulting in the loss of the original insulating performance. In addition, as the temperature rises, the accelerated movement of ions in the capacitor metal may cause the oxide film between the capacitor and the aluminum foil electrode to thicken, thereby reducing the capacitance value of the capacitor. These factors may all affect the performance and stability of the capacitor.

[0004] Capacitors usually have three installation methods: insertion type, surface mount type, and terminal connection type. For the insertion type and surface mount type, the capacitor is directly connected to the circuit board, which is inconvenient for the disassembly and assembly of the capacitor. At the same time, it is necessary to select the appropriate pasting method and bonding process according to the size and specifications of the capacitor, and the installation is very troublesome. The existing terminal connection type can refer to the utility model patent with the publication number of CN204857456U in the Chinese patent literature, which provides a circular core square shell terminal lead-out type capacitor, including a capacitor comprising a housing, a cylindrical capacitor core, and lead-out terminals extending out of the housing. An installation groove for positioning and installing the lead-out terminals is provided on the inner side of the housing. A connecting component for fixedly connecting the cylindrical capacitor core is provided on the lead-out terminal. The connecting component is fixedly connected to the cylindrical capacitor core and installed inside the housing. The lead-out terminal is fixedly inserted into the installation groove through the connecting component. In this solution, the capacitor is arranged inside the housing. When a large amount of heat is generated during the operation of transistors, integrated circuits, resistors, and transformers on the circuit board, the high temperature will affect the performance and stability of the capacitor. Therefore, a connecting terminal that is convenient for capacitor installation and can accelerate the heat dissipation speed of the capacitor is needed to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a capacitor connecting terminal, aiming to solve the technical problems in the prior art that the capacitor connecting terminal cannot enhance the heat dissipation function of the capacitor, the high temperature will affect the performance and stability of the capacitor, and the connection and installation between the capacitor and the circuit board are too complex.

[0006] To achieve the above purpose, a capacitor connecting terminal provided by an embodiment of the present invention includes a bottom plate and a connecting block. The connecting block is vertically arranged on the bottom plate, and an installation groove for installing the capacitor is provided at the upper end of the connecting block. A clearance opening is provided on the bottom plate, and the clearance opening is located below the connecting block.

[0007] Further, the connecting block includes a support plate and a connecting plate. One end of the support plate is connected to the support plate, and the other end is connected to the bottom plate and is located on one side of the clearance opening.

[0008] Further, the connecting plate specifically includes two clamping plates and a positioning plate. The positioning plate is perpendicular to the bottom plate, and the upper and lower ends of the positioning plate are respectively connected to one ends of the two clamping plates. The two clamping plates are parallel to each other and are located on one side of the positioning plate. The end of the lower clamping plate away from the positioning plate is connected to the support plate. An installation groove is formed between the positioning plate and the two clamping plates.

[0009] Further, the clearance opening is located on one side of the bottom plate, and the clearance opening extends through the bottom plate along the direction of the connecting block.

[0010] Further, the bottom plate includes a connecting portion and a bearing portion. One end of the bearing portion is connected to one end of the connecting portion. The connecting block and the clearance opening are located on the bearing portion. A welding hole is provided on the connecting portion.

[0011] Furthermore, the bearing part is higher than the connecting part, and it further includes an adapter plate, with both sides of the adapter plate being connected to one side of the connecting part and one side of the bearing part respectively.

[0012] Furthermore, chamfered parts are provided on both sides of the bottom plate.

[0013] One or more of the above technical solutions in the capacitor connection terminal provided by the embodiment of the present utility model at least have the following technical effects: First, weld the bottom plate on the circuit board, place the capacitor in the installation groove on the connecting block, and then the pins of the capacitor extend through the clearance holes to be connected to the circuit board. Since the connecting block increases the distance between the capacitor and the circuit board, it avoids the heat generated by electronic components such as triodes, integrated circuits, resistors, and transformers on the circuit board from affecting the working performance of the capacitor. At the same time, when placing the capacitor in the installation groove for fixation, compared with the installation method of inserting the capacitor into the circuit board, the installation of this solution is more rapid and convenient.

A clearance opening 11 is provided on the bottom plate 10, and the clearance opening 11 is located below the connection block 20. In this embodiment, first, the bottom plate 10 is welded to the circuit board, the capacitor is placed in the installation groove 21 on the connection block 20, and then the pins of the capacitor extend through the clearance hole to be connected to the circuit board. Since the connection block 20 increases the distance between the capacitor and the circuit board, it avoids the heat generated by electronic components such as triodes, integrated circuits, resistors, and transformers on the circuit board from affecting the working performance of the capacitor. At the same time, when the capacitor is placed and fixed in the installation groove 21, compared with the installation method of inserting the capacitor into the circuit board, the installation of this solution is more rapid and convenient.

[0022] Specifically, referring to Figure 1As shown, the connecting block 20 includes a support plate 22 and a connecting plate 23. One end of the support plate 22 is connected to the support plate 22, and the other end is connected to the bottom plate 10 and is located on one side of the clearance opening 11. In this embodiment, by customizing the height of the support plate 22, the distance between the capacitor and the circuit board is increased, so that the surface of the capacitor can quickly pass through the air, improving the heat dissipation speed of the capacitor. At the same time, it is far away from the heat-generating electronic components on the circuit board, avoiding affecting the performance of the capacitor due to the high-temperature environment.

[0023] Specifically, referring to Figure 1 As shown, the connecting plate 23 specifically includes two clamping plates 24 and a positioning plate 25. The positioning plate 25 is perpendicular to the bottom plate 10, and the upper and lower ends of the positioning plate 25 are respectively connected to one end of the two clamping plates 24. The two clamping plates 24 are parallel to each other and are located on one side of the positioning plate 25. One end of the clamping plate 24 at the lower end away from the positioning plate 25 is connected to the support plate 22. An installation groove 21 is formed between the positioning plate 25 and the two clamping plates 24. In this embodiment, the distance between the two clamping plates 24 is the height of the capacitor. At the same time, one side of the capacitor is abutted against the positioning plate 25 for positioning the capacitor, and the pins of the capacitor pass through the clearance opening 11 to be connected to the circuit board.

[0024] More specifically, referring to Figure 1 As shown, one side of the capacitor is abutted against the positioning plate 25, and the connection end of the capacitor and the positioning plate 25 is fixedly connected by gluing.

[0025] Specifically, referring to Figure 1 As shown, the clearance opening 11 is located on one side of the bottom plate 10, and the clearance opening 11 extends through the bottom plate 10 along the direction of the connecting block 20. In this embodiment, the clearance opening 11 extends through the bottom plate 10 along the direction of the connecting block 20, facilitating the connection of the pins of the capacitor to the circuit board by a soldering gun.

[0026] Specifically, referring to Figure 1 As shown, the bottom plate 10 includes a connecting portion 12 and a bearing portion 13. One end of the bearing portion 13 is connected to one end of the connecting portion 12. The connecting block 20 and the clearance opening 11 are located on the bearing portion 13. A welding hole 14 is provided on the connecting portion 12. In this embodiment, the connecting portion 12 is conveniently welded to the circuit board through the welding hole 14.

[0027] Specifically, referring to Figure 1 As shown, the bearing portion 13 is higher than the connecting portion 12, and further includes an adapter plate 15. Two sides of the adapter plate 15 are respectively connected to one side of the connecting portion 12 and one side of the bearing portion 13. In this embodiment, the bearing portion 13 is higher than the connecting portion 12, increasing the distance between the capacitor and the circuit board, avoiding the heat generated by electronic components such as triodes, integrated circuits, resistors, and transformers on the circuit board from affecting the working performance of the capacitor. At the same time, the contact area between the bottom plate 10 and the circuit board is reduced, saving the space of the circuit board.

[0028] Specifically, referring to Figure 1 As shown, chamfered portions 16 are provided on both sides of the bottom plate 10.
