Description

Technical Field

[0001] This utility model belongs to the field of capacitor casing technology, and in particular relates to a capacitor metal casing that prevents contents from being removed from the casing. Background Technology

[0002] A capacitor is an electronic component that stores electrical energy and releases it in a circuit.

[0003] The capacitor casing is a protective device on the outside of the capacitor, which mainly serves to protect and limit its movement. Because its internal materials are multi-layered and its inner wall is a smooth support surface, the internal materials are prone to sliding and falling off when the device is shaken, affecting its safety and stability during use. Summary of the Invention

[0004] This utility model addresses the problem in the prior art that the inner wall of the outer shell of the device cannot limit the placement of materials and prevent slippage, and proposes the following technical solution:

[0005] A capacitor metal casing for preventing contents from detaching includes a supporting casing and a recessed ring on the upper half of the outer side of the supporting casing. The inner wall of the supporting casing is provided with anti-slip long strips and anti-slip short strips, and there are multiple anti-slip long strips and anti-slip short strips. A buffer space is formed between the adjacent ends of the anti-slip long strips and anti-slip short strips. The inner wall of the supporting casing is provided with multiple compression protrusions. The inner wall of the anti-slip short strips is provided with multiple release grooves.

[0006] The combined use of multiple limiting components can provide reasonable and comprehensive anti-detachment performance for the materials inside the device.

[0007] As a preferred embodiment of the above technical solution, the anti-slip strip is long and the anti-slip short strip is short, and the length of the anti-slip strip is greater than the length of the anti-slip short strip, and both the anti-slip strip and the anti-slip short strip protrude from the inner wall of the supporting shell.

[0008] By setting the lengths of the anti-slip strips and the anti-slip strips to be different, the contact pressure area of ​​the material on the same horizontal plane is made different.

[0009] As a preferred embodiment of the above technical solution, there are several buffer spaces, and the specifications of the several buffer spaces are not the same.

[0010] Because the anti-slip short strips and anti-slip long strips are distributed differently, the size and position of the buffer space are inconsistent.

[0011] As a preferred embodiment of the above technical solution, the extrusion protrusions protrude from the inner wall of the supporting shell, and the extrusion protrusions protrude from the outer side of the anti-slip strip and the anti-slip strip. Several extrusion protrusions are distributed in the same vertical state, and there are several extrusion protrusions at the same horizontal position.

[0012] Supported by the protruding contact between the anti-slip long strip and the anti-slip short strip, a first layer of compression restraint is provided for the internal material.

[0013] As a preferred embodiment of the above technical solution, the release groove is located between two adjacent extrusion protrusions, and the extrusion protrusions are installed on the upper and lower sides and the left and right sides of the release groove.

[0014] The protruding contact of multiple extrusion bumps provides a second layer of extrusion restraint for the internal material.

[0015] As a preferred embodiment of the above technical solution, the extrusion protrusions, the release grooves, the anti-slip strips, and the anti-slip strips are distributed in an overlapping manner.

[0016] By setting the extrusion protrusions, release grooves, anti-slip strips, and anti-slip strips to be staggered, the excessive uniformity at the limiting points can be effectively prevented from causing slippage.

[0017] The beneficial effects of this utility model are as follows:

[0018] (1) With the combined use of multiple limiting components, it can reasonably and comprehensively provide anti-shelling performance for the internal materials of the device;

[0019] (2) By setting the lengths of the anti-slip strips and the anti-slip short strips to be inconsistent, the material has different contact and pressure areas on the same horizontal plane. Furthermore, the anti-slip strips and the anti-slip short strips are installed and distributed inconsistently, so that the material has different pressure positions in the same vertical direction, forming a misaligned extrusion state, which improves the effect of frictional contact.

[0025] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0026] Example

[0027] Figures 1-4 The diagram shown is a schematic representation of the overall structure of a specific embodiment of this utility model. Figures 1-4 In a capacitor metal casing for preventing contents from being ejected, there is a supporting casing 1 and a recessed ring 7 on the upper part of the outer side of the supporting casing 1. The inner wall of the supporting casing 1 is equipped with anti-slip long strips 2 and anti-slip short strips 3, and there are several anti-slip long strips 2 and anti-slip short strips 3. A buffer space 4 is formed between the adjacent ends of the anti-slip long strips 2 and anti-slip short strips 3. The inner wall of the supporting casing 1 is equipped with compression protrusions 5, and there are several compression protrusions 5. The inner wall of the anti-slip short strips 3 is provided with release grooves 6, and there are several release grooves 6.

[0028] First, the supporting shell 1 provides overall positioning for the internal components. The contraction of the concave ring 7 further restricts the upper portion of all components, giving the supporting shell 1 an overall external positioning effect. Second, the anti-slip strips 2 and 3 compress the material inside the supporting shell 1, increasing the friction between the supporting shell 1 and the internal material, thus providing a frictional positioning effect. Simultaneously, the buffer space 4 allows the compressed material to be released within it, creating a concave-convex contact with the material and further enhancing the frictional contact effect. Finally, the protruding compression point 5 provides fixed-point positioning for the internal material, improving the accuracy of the device's positioning and compression. The release groove 6 provides buffer support, releasing the stress generated in the material and ensuring its safety and stability during compression. Thus, the combined use of multiple positioning components provides comprehensive and reasonable anti-detachment performance for the internal material.

[0029] Figure 2 In the middle, the anti-slip strip 2 is long and the anti-slip strip 3 is short. The length of the anti-slip strip 2 is greater than the length of the anti-slip strip 3, and both the anti-slip strip 2 and the anti-slip strip 3 protrude from the inner wall of the supporting shell 1.

[0030] By setting the lengths of the anti-slip long strip 2 and the anti-slip short strip 3 to be inconsistent, the contact pressure areas of the materials on the same horizontal plane are different. Furthermore, the anti-slip long strip 2 and the anti-slip short strip 3 are installed and distributed inconsistently in the same vertical direction, so that the pressure positions of the materials in the same vertical direction are different, forming a staggered extrusion state, which improves the effect of frictional contact and further enhances the anti-detachment effect of the device.

[0031] Figure 3There are several buffer spaces 4, and the specifications of these buffer spaces 4 are not the same.

[0032] Because the anti-slip short strips 3 and anti-slip long strips 2 are distributed differently, the size and position of the buffer space 4 are inconsistent, which enables it to provide staggered support for the internal materials, improve the multidirectionality of the buffer placement, ensure the stability of the local buffer release of the internal materials, and further improve the stability and reliability of its connection.

[0033] Figure 3 and Figure 4 In the middle, the extrusion protrusion 5 protrudes from the inner wall of the supporting shell 1, and the extrusion protrusion 5 protrudes from the outer side of the anti-slip strip 2 and the anti-slip strip 3. Several extrusion protrusions 5 are distributed in the same vertical state, and there are several extrusion protrusions 5 at the same horizontal position.

[0034] The release groove 6 is located between two adjacent extrusion protrusions 5, and extrusion protrusions 5 are installed on the upper and lower sides and the left and right sides of the release groove 6.

[0035] With the support of the anti-slip long strip 2 and the anti-slip short strip 3 protruding in contact, a first layer of compression limiting is provided for the internal material. With the protruding contact of multiple compression protrusions 5, a second layer of compression limiting is provided for the internal material. Furthermore, with the anti-slip long strip 2, the anti-slip short strip 3, and the compression protrusions 5 limiting at different positions and depths, the material placed inside the supporting shell 1 can be fully and comprehensively limited from multiple angles, improving the overall stability of the device in preventing material from falling off the shell. In addition, the protrusion distance of the anti-slip long strip 2, the anti-slip short strip 3, and the compression protrusions 5 is set within the acceptable range for the placed material, ensuring the overall safety of the device during use.

[0036] Figure 3 In the middle, the extrusion protrusions 5, the release grooves 6, the anti-slip strips 2 and 3 are distributed at intersections.

[0037] By setting the extrusion protrusions 5, release grooves 6, anti-slip strips 2, and anti-slip strips 3 in a staggered distribution, they contact the material surface at different positions, which improves the comprehensive and diverse limiting of the material inside the device, while effectively preventing the limiting points from being too uniform and causing slippage.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
