Description

Technical Field

[0001] This utility model relates to the field of conductive foam, specifically a composite conductive foam. Background Technology

[0002] Conductive foam plays a crucial role in numerous fields such as electronic equipment and electromagnetic shielding. Its excellent conductivity and cushioning properties make it widely used in various scenarios to achieve functions such as electromagnetic shielding and grounding connections. However, traditional conductive foam is typically a single, integral structure with a fixed shape and size, making it difficult to flexibly adjust to the complex and varied installation spaces and conductivity requirements of actual applications. For example, in the interiors of irregularly shaped electronic equipment housings, or in electromagnetic shielding structures requiring conductive paths of varying lengths, traditional conductive foam often cannot fit perfectly, leading to installation difficulties and even affecting conductivity and shielding effectiveness.

[0003] To address the issue of fixed dimensions in traditional conductive foam, some existing technologies have proposed splicable conductive foam solutions. However, most of these solutions suffer from poor stability of the spliced ​​structure or complex and cumbersome splicing operations. While some splicing methods can achieve the connection of conductive foam, the spliced ​​parts are prone to loosening. During equipment use, when subjected to external forces such as vibration or compression, the splices are susceptible to separation or misalignment, severely affecting the performance and lifespan of the conductive foam. Other splicing solutions, while ensuring splicing stability to some extent, require complex tools or cumbersome procedures, increasing installation costs and time, and demanding high skill levels from operators, hindering large-scale application.

[0004] In practical applications of conductive foam, it is not only necessary to achieve effective splicing between multiple conductive foams, but also to ensure that the overall structure after splicing can be stably fixed to the workpiece. Some existing conductive foam splicing solutions lack adequate fixing treatment between the spliced ​​parts and the workpiece after splicing, lacking dedicated fixing structures or using unreliable fixing methods. This leads to problems such as shaking and displacement of the spliced ​​conductive foam on the workpiece, failing to meet the requirements of application scenarios with high conductivity and installation stability. Utility Model Content

[0005] The purpose of this invention is to provide a modular conductive foam to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined conductive foam, comprising a conductive sponge block, wherein one side of the conductive sponge block is integrally formed with an assembly block, the other side of the conductive sponge block is provided with an assembly groove, a conductive cloth is sleeved on the outside of the conductive sponge block, and conductive adhesive is provided at the bottom of the portion of the conductive cloth that surrounds the assembly groove.

[0007] Preferably, the assembled block has a "convex"-shaped plate structure, the height of the assembled block is equal to the height of the conductive sponge block, the assembly groove is a "convex"-shaped groove, the assembly groove and the assembled block are matched, after two conductive sponge blocks are spliced end to end, the assembled block on one side of one conductive sponge block is inserted into the assembly groove on one side of the other conductive sponge block.

[0008] Preferably, the bottom surfaces of the conductive sponge block and the conductive cloth are both provided with notch grooves, a conductive adhesive I is inserted into the two groups of notch grooves, the conductive adhesive I is fixed on the top surfaces of the two groups of notch grooves, and the thickness of the conductive adhesive I is greater than the height of the notch grooves.

[0009] Preferably, the bottom surface of the conductive adhesive I is covered with a release paper I, and the top surface area of the release paper I is larger than the bottom surface area of the conductive adhesive I.

[0010] Preferably, a reserved groove is opened at the bottom end of a part of the outer wall of the conductive cloth surrounding the assembly groove, a conductive adhesive II is inserted into the reserved groove, one side of the conductive adhesive II is fixed on the surface of the conductive sponge block, the other side of the conductive adhesive II is covered with a release paper II, and the release paper II covers the notch of the reserved groove.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] For the combined conductive foam proposed by the present utility model, by integrally forming an assembled block with a "convex"-shaped plate structure on one side of the conductive sponge block and opening a matching "convex"-shaped groove-shaped assembly groove on the other side, the function of splicing two conductive sponge blocks end to end is realized. In practical applications, users can freely select an appropriate number of conductive sponge blocks for splicing and combination according to the size, shape of the specific installation space and the requirements of the conductive path. Whether it is a linear, zigzag or other complex-shaped conductive structure, it can be easily realized through this splicing method, greatly improving the applicability and flexibility of the conductive foam, and being able to better meet the conductive and electromagnetic shielding requirements in different scenarios.

[0013] To ensure the stable connection between the spliced conductive sponge blocks, the present utility model sets a conductive adhesive II at the bottom of a part of the conductive cloth surrounding the assembly groove, and opens a reserved groove at the bottom end of its outer wall, inserts the conductive adhesive II into the reserved groove, and one side of the conductive adhesive II is fixed on the surface of the conductive sponge block, and the other side is covered with a release paper II. Before the two conductive sponge blocks are assembled, only need to tear off the release paper II from the surface of the conductive adhesive II. When the two conductive sponge blocks complete the end-to-end assembly through the assembled block and the assembly groove, the conductive adhesive II can serve as an adhesive fixing structure to tightly bond the adjacent conductive sponge blocks together. This design effectively enhances the firmness of the splicing part. Even when the device is running and is subjected to external forces such as vibration and extrusion, the splicing part can remain stable and will not loosen or separate, thus ensuring the conductive performance and electromagnetic shielding effect of the conductive foam and extending its service life.

[0020] In order to clearly and completely describe the purpose and technical solution of the present utility model, and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: a combined conductive foam, including a conductive sponge block 1, one side of the conductive sponge block 1 is integrally formed with an assembling block 3, the other side of the conductive sponge block 1 is provided with an assembling groove 4, the outside of the conductive sponge block 1 is sleeved with a conductive cloth 2, the assembling block 3 is in a "convex" - shaped plate structure, the height of the assembling block 3 is equal to the height of the conductive sponge block 1, the assembling groove 4 is in a "convex" - shaped groove, the assembling groove 4 and the assembling block 3 are matched, after two conductive sponge blocks 1 are spliced end to end, the assembling block 3 on one side of one conductive sponge block 1 is inserted into the assembling groove 4 on one side of the other conductive sponge block 1. When it is necessary to splice two conductive sponge blocks 1 end to end, the assembling block 3 at the end of one conductive sponge block 1 is inserted into the assembling groove 4 at the end of the other conductive sponge block 1 from top to bottom, and one conductive sponge block 1 is pushed down until the top surfaces of the two conductive sponge blocks 1 are coplanar, at this time, the end - to - end splicing of the two conductive sponge blocks 1 is completed.

[0022] Both the conductive sponge block 1 and the conductive cloth 2 have notches 5 on their bottom surfaces. Conductive adhesive 6 is inserted into each of the two sets of notches 5, and is fixed to the top surface of the notches 5. The thickness of the conductive adhesive 6 is greater than the height of the notches 5. Release paper 7 covers the bottom surface of the conductive adhesive 6, and the top surface area of ​​the release paper 7 is larger than the bottom surface area of ​​the conductive adhesive 6.

[0024] Detailed instructions for using this modular conductive foam:

[0025] I. Fixing of a single conductive sponge block 1

[0026] Preparation stage: Check whether the conductive sponge block 1 and the conductive cloth 2 it covers are intact, and ensure that the groove 5, conductive adhesive 6, release paper 7 and other structures are intact and undamaged.

The conductive adhesive 9 is inserted into the reserved groove 8, with one side of the conductive adhesive 9 fixed to the surface of the conductive sponge block 1, and the other side covered with release paper 10, which covers the opening of the reserved groove 8.

[0031] Remove release paper 210: Hold one corner of release paper 210 with your hand and carefully and slowly peel release paper 210 off the surface of conductive adhesive 29 to avoid affecting the adhesion of conductive adhesive 29.

[0032] Assemble the components: Align one end of a conductive sponge block 1 with the assembly block 3 with the end of another conductive sponge block 1 with the assembly groove 4, so that the assembly block 3 is directly above the assembly groove 4. Then, insert the conductive sponge block 1 with the assembly block 3 into the assembly groove 4 of the other conductive sponge block 1 from top to bottom.

[0033] Assembly complete: Push down the conductive sponge block 1 with assembly block 3, applying continuous force until the top surfaces of the two conductive sponge blocks 1 are coplanar.
