Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to an explosion-proof capacitor. Background Art

[0002] A capacitor is a device used to store charge and can store and release electrical energy in a circuit. It typically consists of two conductors separated by a dielectric. When a capacitor is connected to a power source, charge accumulates between its two conductors, forming an electric field. Capacitors' key characteristic is their ability to store and release charge in a short period of time, making them widely used in circuits for energy storage and signal processing.

[0003] In the prior art, capacitors are typically equipped with two bottom-mounted electrode posts. During operation, these two posts need to be connected to specific locations. However, the diameter of these posts is often small, making them prone to breaking during use. Once an electrode post breaks, it is usually impossible and difficult to repair, which often leads to the failure of the entire capacitor. Therefore, those skilled in the art have provided a burst-proof capacitor to address the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an explosion-proof capacitor. By combining the upper and lower explosion-proof mechanisms, the core components of the capacitor are protected, thereby having an explosion-proof function. The electrode column of the lower explosion-proof mechanism is in contact with the electrode connecting sleeve, which ensures conductivity. At the same time, the electrode can be connected to the lower end of the electrode column through a threaded sleeve and a replaceable electrode, which is convenient for replacement when damaged and reduces maintenance costs.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An anti-burst capacitor comprises a capacitor body, an upper anti-burst mechanism is provided at the upper end of the capacitor body, and a lower anti-burst mechanism is provided at the lower end of the capacitor body;

[0007] The upper anti-explosion mechanism includes an upper fixing sleeve, an upper connecting ring is provided on the outer fixing sleeve of the upper fixing sleeve, fixing knobs are provided on both sides of the inner part of the upper connecting ring, and fixing screws are fixedly provided at the lower ends of the two fixing knobs;

[0008] The lower anti-explosion mechanism includes a lower fixing sleeve, and a lower connecting ring is provided outside the lower fixing sleeve. Rotating knobs are provided on both sides of the lower connecting ring, and the two fixing screws are respectively threadedly sleeved into the inside of the two rotating knobs.

[0009] Furthermore, the capacitor body includes a capacitor shell, a limit bar is fixedly provided on one side of the capacitor shell, and two electrode connecting sleeves are fixedly provided on the lower end of the capacitor body.

[0010] Furthermore, two electrode columns are provided through the lower end of the lower fixing sleeve, and a lower connecting thread is provided at the lower end of the lower fixing sleeve near the two electrode columns.

[0011] Furthermore, the exteriors of the two lower connecting threads are both threadedly connected to threaded sleeves, and the lower ends of the two threaded sleeves are both fixedly provided with replaceable electrodes.

[0012] Furthermore, limiting grooves are provided inside the upper fixing sleeve and the lower fixing sleeve, and the two limiting grooves are respectively slidably arranged at the upper and lower end positions of the limiting bar.

[0013] Furthermore, the upper fixing sleeve and the lower fixing sleeve are both made of chloroprene rubber.

[0014] The utility model has the following beneficial effects:

[0015] 1. This utility model proposes an explosion-proof capacitor. By installing an external anti-cracking and explosion-proof mechanism, the capacitor body is effectively fixed inside, achieving wear-resistant protection. At the same time, the external protective measures significantly enhance its explosion-proof performance.

[0016] 2. The utility model proposes an explosion-proof capacitor. By combining a lower explosion-proof mechanism with an upper explosion-proof mechanism, the capacitor can effectively protect its core components from damage, thereby achieving explosion-proof performance. In addition, the electrode column inside the lower explosion-proof mechanism can contact the electrode connection sleeve of the capacitor, ensuring conductivity. The replaceable electrode can be connected to the lower end of the electrode column through the threaded sleeve. This allows for easy replacement of the replaceable electrode if it is damaged, significantly reducing the maintenance cost of the capacitor. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Reference Figure 1 、 Figure 2 The utility model provides an embodiment of an explosion-proof capacitor, comprising a capacitor body 2, an upper explosion-proof mechanism 1 being provided at the upper end of the capacitor body 2, a lower explosion-proof mechanism 3 being provided at the lower end of the capacitor body 2, and the upper fixing sleeve 103 and the lower fixing sleeve 301 being made of chloroprene rubber;

[0025] Specifically, the capacitor is provided with an upper anti-cracking mechanism and a lower explosion-proof mechanism on the outside. The chloroprene rubber therein has good high temperature resistance and corrosion resistance, and is suitable for use as a material for the capacitor anti-explosion sleeve, thereby effectively confining the capacitor body 2 inside, achieving the function of protective wear resistance, and effectively improving the anti-explosion performance through external protection.

[0026] Reference Figure 2 The upper anti-explosion mechanism 1 includes an upper fixing sleeve 103. The outer fixing sleeve of the upper fixing sleeve 103 is provided with an upper connecting ring 101. The inner two sides of the upper connecting ring 101 are provided with fixing knobs 102. The lower ends of the two fixing knobs 102 are fixed with fixing screws 104.

[0027] Specifically, the upper end portion of the capacitor body 2 can be effectively protected by the setting of the upper fixing sleeve 103, and the fixing knob 102 and the fixing screw 104 provided inside can drive the fixing screw 104 to rotate when the fixing knob 102 is rotated, thereby facilitating the connection with the rotating knob 303.

[0028] Reference Figure 2 and Figure 4The lower anti-explosion mechanism 3 includes a lower fixing sleeve 301. The outer fixing sleeve of the lower fixing sleeve 301 is provided with a lower connecting ring 306. The inner sides of the lower connecting ring 306 are both provided with rotating knobs 303. The two fixing screws 104 are respectively threaded into the inner sides of the two rotating knobs 303. The lower end of the lower fixing sleeve 301 is provided with two electrode columns 302. The lower end of the lower fixing sleeve 301 is provided with a lower connecting thread 307 near the position of the two electrode columns 302. The outer sides of the two lower connecting threads 307 are both threadedly connected to the threaded sleeves 304. The lower ends of the two threaded sleeves 304 are fixed with replaceable electrodes 305.

[0029] Specifically, by tightly connecting the lower anti-explosion mechanism 3 to the upper anti-explosion mechanism 1, the capacitor body 2 can be effectively wrapped inside it, thereby achieving an anti-explosion function. This design ensures that the capacitor remains stable even under extreme conditions, avoiding potential safety risks. In addition, an electrode column 302 is provided inside the lower anti-explosion mechanism 3, which can directly contact the electrode connection sleeve 203 in the capacitor, thereby achieving a conductive function. This direct contact method ensures efficient transmission of electrical energy and improves overall energy utilization efficiency. The replaceable electrode 305 can be easily connected to the lower end of the electrode column 302 through the threaded sleeve 304. This design allows the user to directly replace the replaceable electrode 305 when it is damaged or its performance degrades, without having to replace the entire capacitor. This feature greatly reduces the cost of using the capacitor and also reduces the environmental burden caused by replacing the entire capacitor. Ultimately, it not only improves the safety and reliability of the capacitor, but also achieves higher economic and environmental benefits through the design of the replaceable electrode 305.

[0030] Reference Figure 2-4 The capacitor body 2 includes a capacitor housing 201, a limit bar 202 is fixedly provided on one side of the capacitor housing 201, and limit grooves are provided inside the upper fixing sleeve 103 and the lower fixing sleeve 301. The two limit grooves are respectively slidably provided at the upper and lower ends of the limit bar 202, and two electrode connection sleeves 203 are fixedly provided at the lower end of the capacitor body 2;

[0031] Specifically, by setting the limiting strip 202 and the limiting groove, the upper anti-explosion mechanism 1 and the lower anti-explosion mechanism 3 can better correspond to each other when connected, thereby facilitating the connection between the fixing screw 104 and the rotating knob 303, and facilitating the connection of the electrode column 302 to the electrode connecting sleeve 203.

[0032] Working Principle: When using this capacitor, first connect the upper anti-burst mechanism 1 and the lower anti-burst mechanism 3 at the upper and lower positions. During connection, the upper anti-burst mechanism 1 and the lower anti-burst mechanism 3 can be connected at the specified position through the corresponding sliding between the limit groove and the limit bar 202. Then, the fixing screw 104 is connected to the inside of the rotating knob 303 and tightly connected. After the connection is completed, the electrode column 302 will contact the electrode connecting sleeve 203. At the same time, after the threaded sleeve 304 is connected to the upper and lower connecting threads 307, the electrode connecting sleeve 203 is connected to the replaceable electrode 305. At this time, the installation work is completed;

[0033] Secondly, when the replaceable electrode 305 is broken, the broken replaceable electrode 305 can be removed by rotating the threaded sleeve 304 and replaced with a new threaded sleeve 304 and replaceable electrode 305, thereby extending the service life.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
