Description

Technical Field

[0001] This utility model relates to the field of tantalum capacitor technology, specifically an ultra-high voltage plate tantalum capacitor. Background Technology

[0002] As electronic devices continue to evolve towards miniaturization and integration, ultra-high voltage tantalum chip capacitors are increasingly widely used in various high-voltage circuit systems, such as electronic control systems for spacecraft and high-power radar equipment, all of which rely on their stable performance support.

[0003] In practical applications, many high-voltage scenarios require higher withstand voltage values, which a single ultra-high voltage chip tantalum capacitor cannot meet, necessitating the use of multiple capacitors in series. However, existing series connection methods have some drawbacks. On the one hand, the lack of a dedicated organization and fixing mechanism results in a chaotic layout of multiple capacitors on the circuit board, increasing the space occupied by the circuit board and making the overall structure less stable. When the equipment vibrates or is impacted, the capacitors are prone to displacement and collision, affecting the stability of the electrical connection and even causing faults such as short circuits. On the other hand, manual soldering or the use of complex adapters for limiting the position is usually required, making the operation cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide an ultra-high voltage chip tantalum capacitor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0016] Preferably, the fixing mechanism includes:

[0017] Two square plates are provided, which are slidably inserted into the two sides of the top wall of the placement box respectively;

[0018] An arc-shaped hole is formed on the outer wall of one of the square plates;

[0019] There are several arc-shaped holes, which are equally spaced and located on the outer wall of one of the square plates, on one side of the arc-shaped hole.

[0020] Preferably, the guiding mechanism includes:

[0027] Compared with the prior art, the beneficial effects of this utility model are:

[0028] 1. The designed placement box is fixed on the circuit board, providing a neat placement space for multiple ultra-high voltage tantalum chip capacitors. Compared with the traditional series method, the capacitors are arranged in an orderly manner in the storage box, avoiding random distribution on the circuit board, greatly reducing the space occupied by the circuit board, making the circuit board layout more compact and reasonable, which is conducive to the miniaturization and integration of electronic devices.

[0029] 2. With the aid of a guiding mechanism, the second guide pin contacts the negative electrode of the rightmost capacitor before connecting to the circuit board.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0037] Please see Figure 1-4In this embodiment of the utility model, an ultra-high voltage tantalum chip capacitor includes a tantalum capacitor limiting mechanism 100. The tantalum capacitor limiting mechanism 100 includes a placement box 110, which is fixed to a circuit board. A fixing mechanism 200 is fixed to the top of the placement box 110, which can limit the ultra-high voltage tantalum chip capacitor. The guiding mechanism 300 slides inside one side of the placement box 110, which can adjust the electrical connection position. The tantalum capacitor limiting mechanism 100 includes a slot 114, which is provided in a plurality of them and is equally spaced inside the placement box 110 near the bottom. The slots 114 are connected at one end. A lead-out terminal 120 is fixedly connected inside the slot 114. The placement box 110 is fixed to the circuit board by the design, providing a regular placement space for multiple ultra-high voltage tantalum chip capacitors.

[0038] The tantalum capacitor limiting mechanism 100 includes: a second slot 115, which is located inside the placement box 110 on one side at the same level as the first slot 114; a third slot 116, which is located inside the placement box 110 on the other side at the same level as the first slot 114; and two lead-out terminals 121, which are respectively fixed inside the second slot 115 and the third slot 116. One of the lead-out terminals 121 has a guide pin 122 fixedly connected to its outer wall, and the outer wall of the guide pin 122 is inserted into the circuit board. The guiding mechanism 300 includes: a square groove 310, which is located on one side of the top wall of the placement box 110, and an insulating block 322 is slidably inserted into the square groove 310; and an insulating rod 321, which is fixed to the circuit board. On the outer wall of the insulating block 322, and the outer wall of the insulating rod 321 is slidably connected to the arc-shaped hole 211 and the arc-shaped hole 212. The guide foot 2 320 is fixed at one end of the insulating rod 321, and the guide foot 2 320 is closely attached to the outer wall of the lead-out terminal 120 and one of the lead-out terminals 2 121 and slidably inserted into the inner wall of the square groove 310. The lead-out terminal 311 is fixed at the bottom of the square groove 310, and the lead-out terminal 311 is slidably inserted into the guide foot 2 320. One end of the lead-out terminal 311 is inserted into the circuit board. Through the setting of the guide mechanism 300, the guide foot 2 320 contacts the negative electrode of the rightmost capacitor and then connects to the circuit board. With the cooperation of other connection structures in the placement box 110, the entire series connection process is completed.

[0039] The fixing mechanism 200 includes: two square plates 210, which are slidably inserted into the top walls of the placement box 110 respectively; an arc-shaped hole 211, which is opened on the outer wall of one of the square plates 210; and several arc-shaped holes 212, which are equally spaced on the outer wall of one of the square plates 210 located on one side of the arc-shaped hole 211. The square plates 210 not only provide a good fixing effect for the capacitor, but also limit the position of the insulating rod 321, making it convenient for personnel to adjust the position of the insulating rod 321 and fix it.

[0040] Specifically, during operation, in practical applications, the placement box 110 is fixed at a designated position on the circuit board. When multiple ultra-high voltage tantalum chip capacitors need to be connected in series, the tantalum capacitors are sequentially snapped into the placement racks within the placement box 110. Each placement rack within the placement box 110 is equipped with a lead-out terminal 120, allowing the negative and positive leads of adjacent capacitors to be electrically connected through the lead-out terminal 120, ensuring that current can be sequentially transferred between the capacitors. The positive lead of the ultra-high voltage tantalum chip capacitor placed at one end of the placement box 110 contacts the lead-out terminal 121 in the slot 115, and the lead pin 122 fixed to the lead-out terminal 121 is inserted into the circuit board, thus connecting to the positive terminal of the circuit. In addition, the guide mechanism 300 provided in the placement box 110 guides the capacitors after all capacitors are installed. After installation, the insulating rod 321 is moved so that its second guide foot 320 contacts the negative electrode guide plate of the ultra-high voltage tantalum chip capacitor at the far right, completing the negative electrode connection of the entire capacitor series circuit. One end of the third lead-out terminal 311 is connected to the circuit board, realizing the electrical connection between the entire series circuit and the circuit board. After installation, the two square plates 210 are pushed together to fit tightly against the top wall of the ultra-high voltage tantalum chip capacitor, limiting their position and limiting the insulating rod 321 at the current position. The bolts are then turned to limit the square plates 210. This structure not only ensures good electrical contact, but also prevents the guide plate from becoming loose due to vibration, displacement, or other factors during equipment operation, ensuring stable current transmission between the series capacitors, thereby meeting the withstand voltage requirements of the high voltage circuit and ensuring the normal operation of the high voltage circuit system.

[0041] Example 1

[0042] like Figure 1-3 As shown, in this embodiment, the tantalum capacitor limiting mechanism 100 includes: a plurality of slots 114, which are equally spaced and located inside the placement box 110 near the bottom, and one end of each of the slots 114 is connected to the other. A lead-out terminal 120 is fixedly connected inside the slot 114.

[0043] In this embodiment, during practical application, the placement box 110 is fixed at a designated position on the circuit board. When multiple ultra-high voltage tantalum chip capacitors need to be connected in series, the tantalum capacitors are sequentially snapped onto the placement racks within the placement box 110. Each placement rack within the placement box 110 is provided with a lead-out terminal 120, allowing the negative and positive leads of adjacent capacitors to be electrically connected through the lead-out terminal 120, ensuring that current can be sequentially transferred between the capacitors. The placement box 110, through its design, is fixed to the circuit board, providing a mounting system for multiple ultra-high voltage tantalum chip capacitors. It provides a neat placement space. Compared with the traditional series connection method without a fixed mechanism, the capacitors are arranged in an orderly manner in the storage box, avoiding random distribution on the circuit board. This greatly reduces the space occupied by the circuit board, making the circuit board layout more compact and reasonable. It is conducive to the miniaturization and integration of electronic devices. Moreover, the ultra-high voltage plate tantalum capacitors only need to be snapped into the placement box 110. Through the pre-set lead-out terminal 120 inside the storage box, the negative electrode plate can be connected to the adjacent positive electrode plate, realizing quick series installation, which effectively improves work efficiency and operation convenience.

[0044] like Figure 2-4 As shown, in this embodiment, the tantalum capacitor limiting mechanism 100 includes: a second slot 115, which is opened inside the placement box 110 on one side at the same level as the first slot 114; a third slot 116, which is opened inside the placement box 110 on the other side at the same level as the first slot 114; and two lead-out terminals 121, which are respectively fixed inside the second slot 115 and the third slot 116. One of the lead-out terminals 121 has a guide pin 122 fixedly connected to its outer wall, and the outer wall of the guide pin 122 is inserted into the circuit board. The guiding mechanism 300 includes: a square groove 310, which is opened in the placement box 110. On one side of the top wall, an insulating block 322 and an insulating rod 321 are slidably inserted into the square groove 310. The insulating rod 321 is fixed to the outer wall of the insulating block 322, and the outer wall of the insulating rod 321 is slidably connected to the arc-shaped hole 211 and the arc-shaped hole 212. The guide foot 320 is fixed to one end of the insulating rod 321, and the guide foot 320 is closely attached to the outer wall of the lead-out terminal 120 and one of the lead-out terminals 121 and slidably inserted into the inner wall of the square groove 310. The lead-out terminal 311 is fixed to the bottom of the square groove 310, and the lead-out terminal 311 is slidably inserted into the guide foot 320. One end of the lead-out terminal 311 is inserted into the circuit board.

[0045] In practice, the positive electrode of the ultra-high voltage tantalum chip capacitor placed at one end of the placement box 110 contacts the lead-out terminal 121 in the slot 115. The lead-out pin 122 fixed to the lead-out terminal 121 is then inserted into the circuit board, thus connecting to the positive terminal of the circuit. In addition, the guide mechanism 300 in the placement box 110, after all capacitors are installed, moves the insulating rod 321 to make its lead-out pin 320 contact the negative electrode of the rightmost ultra-high voltage tantalum chip capacitor, completing the negative terminal connection of the entire capacitor series circuit. One end of the lead-out terminal 311 is connected to the circuit board, realizing the electrical connection between the entire series circuit and the circuit board. With the guide mechanism 300, the lead-out pin 320 contacts the negative electrode of the rightmost capacitor and then connects to the circuit board. In conjunction with other connection structures in the placement box 110, the entire series process is completed. This connection method eliminates the need for traditional manual welding or complex adapters, does not require conductive adhesive, greatly reduces the technical requirements for operators, reduces connection operation time, and significantly improves production efficiency.

[0046] Example 2

[0047] like Figure 1 As shown, in this embodiment, the fixing mechanism 200 includes: two square plates 210, which are slidably inserted into the top walls of the placement box 110 respectively; an arc-shaped hole 211, which is opened on the outer wall of one of the square plates 210; and several arc-shaped holes 212, which are equally spaced on the outer wall of one of the square plates 210 located on one side of the arc-shaped hole 211.

[0048] In practice, after installation, the two square plates 210 are pushed together towards the center, tightly fitting the top wall of the ultra-high voltage tantalum chip capacitor to limit its position and also limit the insulating rod 321 at its current position. This structure not only ensures good electrical contact but also prevents the conductor plates from becoming loose due to vibration, displacement, or other factors during equipment operation, ensuring stable current transmission between the series-connected capacitors. This meets the withstand voltage requirements of the high-voltage circuit and guarantees the normal operation of the high-voltage circuit system. The square plates 210 not only provide good fixation for the capacitor but also limit the insulating rod 321, making it convenient for personnel to adjust and fix the position of the insulating rod 321. In addition, the limiting effect of the two square plates 210 prevents the capacitor from easily shifting or colliding when the equipment vibrates or is impacted. This effectively ensures the stability of the electrical connection, reduces the risk of short circuits and other faults caused by capacitor displacement, improves the reliability and stability of the high-voltage circuit system, and reduces equipment failure maintenance costs.
