Description

Technical Field

[0001] The present application relates to the technical field of electronic components, and in particular to a sealing upper cover for a capacitor housing. Background Art

[0002] When in use, capacitors need to be covered with a shell for protection. The capacitor contains key components such as dielectrics and electrodes, which are relatively sensitive to the external environment. Placing the capacitor inside the shell can effectively protect these components from external factors such as mechanical damage, pollutants, and moisture, thereby improving the stability and reliability of the capacitor. The shell can also provide additional electrical isolation and insulation to prevent unnecessary contact between the dielectric or electrodes inside the capacitor and the external environment, thereby reducing the risk of electrical failures and circuit short circuits.

[0003] However, the existing shells used to protect capacitors have low strength and are prone to damage the capacitors inside. Utility Model Content

[0004] In view of this, the present application proposes a sealing upper cover for a capacitor housing to improve the overall strength.

[0005] According to one aspect of the present application, there is provided a sealing upper cover for a capacitor housing, comprising: an upper cover;

[0006] The upper cover is a plate-like structure, with an installation side wall provided along the edge of the upper cover. The upper cover is suitable for matching the opening of the capacitor housing, and the upper cover is provided with a first reinforcing rib along the length direction. The installation side wall is provided with a second reinforcing rib in a direction perpendicular to the upper cover, one end of the second reinforcing rib is connected to the first reinforcing rib, and the other end extends to the outside of the installation side wall.

[0007] In a possible implementation, the upper cover is embedded in the top opening of the shell, and the second reinforcing rib of the upper cover extends toward the bottom of the shell.

[0008] In one possible implementation, the second reinforcing rib is a columnar structure, and the cross-section of the second reinforcing rib is semicircular;

[0009] The second reinforcing rib is a planar side wall that is attached to and fixed to the inner side of the mounting side wall.

[0010] In one possible implementation, there are two second reinforcing ribs, which are symmetrically arranged on both sides of the upper cover.

[0011] In one possible implementation, the side wall of the upper cover is provided with a fixing portion, which extends in a direction perpendicular to the side wall of the upper cover, and the fixing portion at the extended position of the side wall of the upper cover is suitable for matching with a fixing hole provided at the opening position of the shell.

[0012] In one possible implementation, the height of the fixing portion increases from the bottom to the top of the upper cover.

[0013] In a possible implementation, there are more than two fixing portions, which are spaced apart along the circumferential direction of the upper cover.

[0014] In one possible implementation, the extension length of the second reinforcing rib is in the range of 1 / 2-2 / 3 of the height of the installation side wall.

[0015] In one possible implementation, the upper cover, the mounting side wall, the first reinforcing rib and the second reinforcing rib are integrally formed.

[0016] In one possible implementation, a mark is preset on the top of the upper cover.

[0017] The sealed upper cover for a capacitor housing according to the present invention has the following beneficial effects: by providing a first reinforcing rib along the length of the interior of the housing, a first reinforcing rib along the inner side of the upper cover, a second reinforcing rib along the mounting sidewall perpendicular to the upper cover, and a fourth reinforcing rib along the length of the exterior of the housing, the mounting strength of the housing and the upper cover is improved. Specifically, the first and fourth reinforcing ribs are used to increase the strength of the housing in the direction of the opening, and enhance the strength of both the interior and exterior sides of the housing, respectively. The first reinforcing rib is used to increase the strength of the upper cover in the length direction, and the second reinforcing rib is used to increase the strength of the mounting sidewall perpendicular to the upper cover, thereby comprehensively improving the strength of the housing and the upper cover.
