[0002] Combined non-solid electrolyte tantalum capacitors are widely used in various civilian and military electronic products due to their many excellent properties, such as small size, high voltage, large capacitance, low leakage current, low loss (low ESR), long life, good storage stability, excellent frequency characteristics, and ability to withstand large ripple current.

[0003] As usage scenarios become increasingly complex and user requirements for capacitors become more customized, there is an urgent need to manufacture a more robust, explosion-proof, modular tantalum capacitor. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a combined tantalum capacitor with explosion-proof function.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a combined tantalum capacitor with explosion-proof function, including a shell, mounting pins fixedly connected to both opposite sides of the shell surface, a positive lead and a negative lead installed on the outside of the shell, an explosion-proof cover provided at the opening end of the shell, and multiple mounting posts provided along the edge of the opening of the shell, with the explosion-proof cover fixedly connected to the mounting posts by screws.

[0007] Preferably, the explosion-proof cover has multiple grooves along its circumference, and the bottom of the grooves is through-hole.

[0008] Preferably, a tie rod connects the housing and the mounting pin.

[0009] Preferably, an extension plate is provided at the bottom of the outer casing.

[0010] Preferably, the extension plate has multiple grooves on its surface.

[0011] Preferably, the positive lead and the negative lead are led out in the same direction.

[0012] Preferably, both the positive and negative leads are made of high-temperature silver-plated copper wire.

[0013] Preferably, the outer casing is made of aluminum alloy.

[0014] The beneficial effects of this utility model are as follows: by using screws to pass through the explosion-proof cover and threadedly connect it to the mounting column, the overall structure of the structure is strengthened, ensuring the structural encapsulation strength and having a certain explosion-proof effect. At the same time, the gas inside the structure is released through the groove, which helps to enhance the overall explosion-proof function of the structure. Attached Figure Description

Detailed Implementation

[0016] 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.

[0017] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0018] In this embodiment, refer to Figure 1 and Figure 2 The device includes a housing 1, which is made of aluminum alloy. Mounting pins 12 are fixedly connected to both opposite sides of the surface of the housing 1. Two mounting pins 12 are integrally connected to each side. Each mounting pin 12 is fixedly connected to the surface of the housing 1 with a bracing 13 to strengthen the strength between the mounting pin 12 and the housing 1.

[0019] In this embodiment, refer to Figure 1The outer side of the outer casing 1 is equipped with a positive lead 3 and a negative lead 4. The positive lead 3 and the negative lead 4 are led out in the same direction. The positive lead 3 and the negative lead 4 are located between two mounting pins 12 on one side. Both the positive lead 3 and the negative lead 4 are made of high-temperature silver-plated copper wire. The positive lead 3 uses red high-temperature silver-plated copper wire, and the negative lead 4 uses black high-temperature silver-plated copper wire to facilitate the distinction between positive and negative terminals.

[0020] In this embodiment, refer to Figure 1 and Figure 3 An explosion-proof cover 2 is provided at the opening end of the outer shell 1. Multiple mounting posts 11 are provided along the edge of the opening of the outer shell 1. The mounting posts 11 are integrally formed with the outer shell 1. The multiple mounting posts 11 are evenly distributed. Threaded holes are provided on the mounting posts 11. Screws 21 are threaded through the explosion-proof cover 2 and threadedly connected to the threaded holes to strengthen the stable connection between the explosion-proof cover 2 and the outer shell 1, thereby achieving the encapsulation of the explosion-proof cover 2 and the outer shell 1.

[0021] In this embodiment, refer to Figure 1 The explosion-proof cover 2 has multiple grooves 22 along its circumference. The bottom of the grooves 22 is through-hole, which allows the outside and inside of the structure to be connected, facilitating the discharge of gas inside the structure, thereby helping to enhance the explosion-proof effect of the overall structure.

[0022] In this embodiment, refer to Figure 2 An extension plate 14 is provided at the bottom of the outer casing 1 to accommodate special installation positions of the user.

[0023] In this embodiment, refer to Figure 2 Multiple grooves 15 are provided on the surface of the extension plate 14, which helps to reduce the weight of the entire structure.

[0024] The working principle of this utility model is as follows: By setting multiple mounting posts 11, screws 21 pass through the explosion-proof cover 2 and are fixedly connected to the mounting posts 11 to strengthen the connection between the outer shell 1 and the explosion-proof cover 2. A groove 22 is opened on the explosion-proof cover 2 to facilitate the discharge of internal gas. A tie rod 13 is also used to reinforce the outer shell 1 and the mounting pins 12, which helps to strengthen the stability of the external structure of the outer shell 1 and strengthen and stabilize the entire structure, providing a certain explosion-proof function and adapting to more complex usage scenarios.
