[0002] Surface mount aluminum electrolytic capacitors are a type of surface-mount aluminum electrolytic capacitor. As an indispensable component in electronic circuits, they are used to store charge and filter, ensuring stable circuit operation. They are widely used in artificial intelligence, AI computing, new energy vehicles, 5G communication, battery energy storage, chips, and other fields. In order to improve the efficiency of fixed capacitors, it is necessary to improve their related structures.

[0003] Meanwhile, a surface-mount aluminum electrolytic capacitor packaging structure, with application number CN202420838747.3, includes a connector. A frame is installed inside the connector, and a limiting mechanism is installed inside the frame. A capacitor body is attached to the surface of the connector, and a set of through holes are formed on the surface of the connector. This device can limit and fix the capacitor body, indirectly improving the fixing efficiency and preventing displacement or detachment during soldering. The operation is very simple, and this design greatly increases practicality.

[0004] However, the following problems were found in the implementation of the relevant technology: Although the existing device improves the fixing efficiency, the protection after fixing is not sufficient, which makes the electrolytic capacitor body easy to loosen after fixing. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an explosion-proof liquid-state chip aluminum electrolytic capacitor, which offers more adequate protection for the electrolytic capacitor body and is less prone to loosening after fixing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof liquid surface mount aluminum electrolytic capacitor, comprising a base, an electrolytic capacitor body installed in the middle of the base, and an explosion-proof component installed between the two. The explosion-proof component includes an annular groove constructed on the upper part of the base and a connecting ring disposed on the upper part of the annular groove. The connecting ring is fixedly sleeved on the side wall of the electrolytic capacitor body. Two injection holes are symmetrically opened on the top of the connecting ring. Two arc-shaped protective sleeves are symmetrically sleeved on the side wall of the electrolytic capacitor body and are adhered to the top of the base. Connecting parts are integrally formed on the left and right sides of the protective sleeves, and connecting screws are screwed between the two connecting parts on the same side. Protective plates located on the top of the electrolytic capacitor body are integrally formed on the inner top of the two protective sleeves.

[0007] Preferably, the corresponding sides of the two protective sheets abut against each other, and the top of the protective sheets are evenly provided with a plurality of heat dissipation holes.

[0008] Preferably, the protective sleeve and the connector, as well as the protective sleeve and the protective sheet, are all injection-molded integral structures.

[0009] Preferably, the tail of the connecting screw is screwed with a nut, and the nut abuts against the rear side of the rear connector.

[0010] Preferably, the injection hole is located below the gap between the two protective sleeves, and the inner diameter of the protective sleeve is the same as the outer diameter of the electrolytic capacitor body.

[0011] Preferably, a sticker is adhered to the top of the electrolytic capacitor body, and a protective film is adhered to the surface of the sticker.

[0012] Preferably, the bottom of the electrolytic capacitor body is symmetrically connected with two pins, and the bottom of the base is constructed with pin holes through which the pins pass.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The electrolytic capacitor body of this utility model is protected by two protective sleeves and a protective plate on top after being fixed. This provides a certain degree of protection against external impact. In addition, the connecting ring on the side wall of the electrolytic capacitor body is glued to the corresponding side of the base by injection to improve the stability of the connection. The protection of the electrolytic capacitor body is more sufficient and the connection is not easy to loosen after being fixed.

[0015] 2. In this invention, after the electrolytic capacitor body is inserted into the inner side of the base, glue is injected through the glue injection hole. Then, two protective sleeves are fitted onto the side wall of the electrolytic capacitor body and fixed with connecting screws to complete the installation of the explosion-proof component. The installation of the explosion-proof component is relatively convenient. Attached Figure Description

[0021] 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.

[0022] like Figures 1 to 4 As shown, this utility model provides an explosion-proof liquid surface mount aluminum electrolytic capacitor, including a base 1, an electrolytic capacitor body 2 installed in the middle of the base 1, and an explosion-proof component installed between the two. The explosion-proof component includes an annular groove 3 constructed on the upper part of the base 1 and a connecting ring 4 disposed on the upper part of the annular groove 3. The connecting ring 4 is fixedly sleeved on the side wall of the electrolytic capacitor body 2. Two glue injection holes 5 are symmetrically opened on the top of the connecting ring 4. Glue can be injected into the annular groove 3 through the glue injection holes 5, so that the connecting ring 4 can be firmly connected to the top of the annular groove 3. This also improves the stability of the electrolytic capacitor body 2 installed in the middle of the base 1. Two arc-shaped protective sleeves 6 are symmetrically fitted on the wall. The two protective sleeves 6 can cover the side wall of the electrolytic capacitor body 2, preventing external impacts from directly affecting the electrolytic capacitor body 2 and providing a certain degree of protection. The protective sleeves 6 are adhered to the top of the base 1. Connecting parts 7 are integrally formed on both the left and right sides of the protective sleeves 6, and connecting screws 8 are screwed between the two connecting parts 7 on the same side. By fixing the connecting parts 7 on both sides with the connecting screws 8, the two protective sleeves 6 can be fixed to the outside of the electrolytic capacitor body 2. The top of the inner side of the two protective sleeves 6 is integrally formed with a protective plate 9 located on the top of the electrolytic capacitor body 2, which can provide protection for the top of the electrolytic capacitor body 2.

[0023] Specifically, the corresponding sides of the two protective plates 9 abut against each other, and multiple heat dissipation holes 10 are evenly opened on the top of the protective plates 9. While providing protection, the heat dissipation effect at this point can be guaranteed, and the heat generated by the electrolytic capacitor body 2 can be prevented from being dissipated.

[0024] Furthermore, the protective sleeve 6 and the connector 7, as well as the protective sleeve 6 and the protective sheet 9, are all injection-molded integral structures. The injection-molded integral structure has high strength and is not easily damaged.

[0025] Furthermore, a nut (not shown in the figure) is screwed to the tail of the connecting screw 8, and the nut abuts against the rear side of the rear connector 7, which can increase the stability of the connecting screw 8 connecting the two connectors 7.

[0026] It is worth noting that the glue injection hole 5 is located below the gap between the two protective sleeves 6 to avoid affecting the glue injection due to changes in the installation order. In addition, the inner diameter of the protective sleeve 6 is the same as the outer diameter of the electrolytic capacitor body 2, ensuring that the protective sleeve 6 can fit tightly against the side wall of the electrolytic capacitor body 2, thus achieving a better protective effect.

[0027] It is worth noting that a sticker 11 is attached to the top of the electrolytic capacitor body 2. The surface of the sticker 11 is marked with the parameter information of the current electrolytic capacitor body 2, and a protective film is attached to the surface of the sticker 11 to prevent wear and tear, so as to avoid the parameter information becoming unclear.

[0028] It is worth mentioning that the bottom of the electrolytic capacitor body 2 is symmetrically connected with two pins 12, and the bottom of the base 1 is constructed with pin holes 13 for the pins 12 to pass through so as to be soldered and fixed.

[0029] The device's "front, back, left, and right" perspectives are... Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle: The electrolytic capacitor body 2 is inserted into the middle of the base 1, with the pins 12 passing through the corresponding pin holes 13. At this time, the connecting ring 4 is located at the upper part of the annular groove 3. Then, glue is injected into the annular groove 3 through the glue injection hole 5 to bond and fix the connecting ring 4. Next, two protective sleeves 6 are fitted onto the outer wall of the electrolytic capacitor body 2 and bonded to the top of the base 1. Then, the connecting parts 7 on both sides are fixed by the connecting screws 8 to complete the installation of the explosion-proof component. After being fixed, the electrolytic capacitor body 2 is protected by the two protective sleeves 6 and the protective plate 9 on the top. This provides a certain degree of protection against external impact. In addition, the connecting ring 4 on the side wall of the electrolytic capacitor body 2 is bonded to the corresponding side of the base 1 by glue injection to improve the stability of the connection. The protection of the electrolytic capacitor body 2 is more sufficient, and the connection is not easy to loosen after fixing.
