Description

Technical Field

[0001] This application relates to the technical field of capacitors, and particularly to a capacitor housing. Background Art

[0002] Capacitors have a very diverse and important role in electronic circuits and systems. They can be used for storing electrical energy: Capacitors can store charge and electrical energy, and this property enables capacitors to release energy when needed, such as in flashlights, pulse-forming circuits, and certain power supply circuits, as well as filtering: In power supply circuits, capacitors are often used as filtering components to reduce the ripple voltage in the power supply and provide a stable operating voltage for the circuit. A capacitor typically consists of two conductive plates (or electrodes) separated by a layer of insulating medium. This insulating medium can be solid, gas, or liquid. For certain types of capacitors (such as electrolytic capacitors or wet capacitors), the insulating medium is a liquid electrolyte. However, when the capacitor is placed inside the housing, the solidified liquid electrolyte has a small contact area with the capacitor after solidification, and the fixed installation effect is poor. Summary of the Utility Model

[0003] In view of this, this application proposes a capacitor housing to improve the fixed installation effect between the capacitor and the housing after the poured liquid electrolyte solidifies.

[0005] The housing is a hollow structure with one end open, and is suitable for placing a capacitor inside;

[0006] The reinforcing ribs are strip-shaped structures with a preset thickness, and the reinforcing ribs are arranged on the inner side wall of the housing along the opening direction of the housing, extending towards the center direction of the housing. There are two or more reinforcing ribs, which are arranged at intervals along the circumferential direction of the housing.

[0007] In a possible implementation manner, two or more of the reinforcing ribs are symmetrically arranged with respect to the center line of the housing.

[0008] In a possible implementation manner, the length of the reinforcing rib is less than the opening depth of the housing, and the reinforcing rib is located at the middle position of the housing.

[0009] In a possible implementation manner, the cross-section of the opening direction of the housing is rectangular, and both ends in the length direction are arc-shaped.

[0010] In a possible implementation manner, it further includes: a support member;

[0011] The support member is a columnar structure, disposed at the inner bottom end of the housing, and the support member has a preset thickness, spacing the capacitor from the inner bottom end of the capacitor housing.

[0012] In a possible implementation manner, there are two or more of the support members, which are spaced along the length direction of the inner bottom end of the housing.

[0013] In a possible implementation manner, explosion-proof grooves are formed on the side wall of the support member, and the explosion-proof grooves penetrate along the length direction of the support member;

[0014] There are two or more of the explosion-proof grooves, which are spaced along the circumferential direction of the support member.

[0015] In a possible implementation manner, the spacing distance between any two adjacent explosion-proof grooves is in the range of 1 mm - 1.5 mm.

[0028] In addition, for better illustration of the present application, numerous specific details are given in the following detailed implementation manners. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some instances, methods, means, elements, and circuits well-known to those skilled in the art are not described in detail so as to highlight the gist of the present application.

[0029] Refer to Figure 1 、 Figure 2 and Figure 3, the capacitor housing of the embodiment of the present application includes: a housing 100 and a reinforcing rib 200. The housing 100 is a hollow structure with one end open, and is suitable for placing a capacitor inside. The reinforcing rib 200 is a strip-shaped structure with a preset thickness, and the reinforcing rib 200 is arranged on the inner side wall of the housing 100 along the opening direction of the housing 100, extending towards the central direction of the housing 100. There are more than two reinforcing ribs 200, which are arranged at intervals along the circumferential direction of the housing 100.

[0030] In this embodiment, by arranging the reinforcing rib 200 inside the housing 100, and the strip-shaped reinforcing rib 200 is arranged along the opening direction of the housing 100, the strength of the housing 100 in the length direction is increased, and the safety performance of the capacitor placed inside is improved. Moreover, the reinforcing rib 200 extends towards the central direction of the housing 100. When a capacitor is provided inside the housing 100 and the poured electrolyte is cured, the extended reinforcing rib 200 can provide support for the cured electrolyte, so as to play a role in protecting the capacitor, isolating the internal structure of the capacitor from the external environment, and preventing damage from external environment and accidental collisions and other factors, thereby ensuring the normal operation of the capacitor.

[0031] In a specific embodiment, more than two reinforcing ribs 200 are symmetrically arranged with respect to the center line of the housing 100. The symmetrically arranged reinforcing ribs 200 can provide a more stable supporting force with respect to the housing 100 and the cured electrolyte, and provide a more balanced force for the internally arranged capacitor.

[0032] In a specific implementation, the length of the reinforcing rib 200 is less than the opening depth of the housing 100, and the reinforcing rib 200 is located at the middle position of the housing 100. The reinforcing rib 200 is completely located inside the housing 100, and when the reinforcing rib 200 is arranged at the middle position of the inner side wall of the housing 100, it can provide support for the middle position of the side wall of the housing 100.

[0033] In a specific implementation, the cross-section of the opening direction of the housing 100 is rectangular, and the two ends in the length direction are arc-shaped. Among them, the number of the reinforcing ribs 200 is six, two are respectively arranged on the side wall of the housing 100 with an arc-shaped cross-section, two are arranged on one side wall of the housing 100 with a rectangular cross-section, and two are arranged on the other side wall of the housing 100 with a rectangular cross-section.

[0034] In a specific implementation, the capacitor housing 100 further includes: a support member 300, which is a columnar structure, disposed at the inner bottom end of the housing 100, and the support member 300 has a preset thickness, spacing the capacitor from the inner bottom end of the capacitor housing 100. By providing the support member 300 at the inner bottom end of the housing 100, the capacitor placed inside has a distance from the inner bottom end of the housing 100. The support member 300 is provided with a support member 310 along the length direction of the housing 100, increasing the area where the capacitor housing 100 can contact the electrolyte.

[0035] In a specific implementation, there are two or more support members 300, which are spaced along the length direction of the inner bottom end of the housing 100 and are matched with the shape of the capacitor.

[0036] In a specific implementation, in a specific embodiment, the side wall of the support member 300 is provided with a support member 310, and the support member 310 penetrates along the length direction of the support member 300, enabling the bottom of the capacitor to correspond to the inner bottom end of the housing 100 through the penetrated support member 310, allowing the electrolyte to flow between the bottom of the capacitor and the inner bottom end of the housing 100.

[0037] In this embodiment, there are two or more support members 310, which are spaced along the circumferential direction of the support member 300, further enhancing the contact area between the capacitor and the electrolyte.

[0038] In this embodiment, there is a preset distance between the support member 300 and the inner side wall of the housing 100, and the preset distance is 1 / 20 of the length of the capacitor. Specifically, when the capacitor is placed on the support member 300 inside the housing 100, the opening position of the housing 100 can cover the top of the capacitor.

[0039] In this embodiment, the spacing distance between any two adjacent support members 310 is in the range of 1 mm - 1.5 mm. The adjacent two support members 310 have a relatively small spacing distance, which can further enhance the contact area between the bottom of the capacitor and the electrolyte.

[0040] In a specific embodiment, the cross-section of the support member 310 along the length direction of the support member 300 is arc-shaped. The arc-shaped support member 310 facilitates the flow of the electrolyte in a liquid state, enabling the electrolyte to fill the support member 310.

[0041] In a specific embodiment, the opening of the housing 100 is provided with capacitor pin mounting grooves. There are two capacitor pin mounting grooves, which are arranged along the circumferential direction of the housing 100 for passing through the capacitor pins of the capacitor, keeping the top of the housing 100 flush.

[0042] The embodiments of the present application have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The choice of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to technologies in the market, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
