Description

Technical Field

[0001] This utility model relates to the field of conductive foam technology, specifically to a conductive foam with cushioning and protective functions. Background Technology

[0002] Conductive foam is a commonly used functional component in the field of electronic equipment. It is widely used in products such as circuit boards, displays, and communication modules. It mainly undertakes core functions such as conductivity, electromagnetic shielding, and gap filling. It is a key component to ensure the stability of signal transmission and electromagnetic compatibility of electronic equipment.

[0003] However, existing conductive foam products generally suffer from a lack of functional design: on the one hand, most products focus only on conductivity, neglecting cushioning and protection capabilities. During the transportation, installation, or daily use of electronic equipment, external impacts and vibrations can easily deform or damage the conductive foam structure, not only disrupting its conductive path and affecting signal transmission efficiency, but also potentially causing short circuits and malfunctions due to foam failure. On the other hand, the flame-retardant properties of some conductive foams fail to meet high safety standards, making them prone to combustion and releasing harmful gases in high-temperature environments or upon accidental contact with fire sources, posing safety hazards to electronic equipment and the environment in which they are used.

[0004] Meanwhile, the existing connection methods between conductive foam and equipment protection structures also have defects. Traditional connections often rely on simple adhesives or direct bonding, which are prone to detachment and displacement after long-term use, further weakening their protective and supportive role for electronic equipment. These problems make it difficult for existing conductive foam to meet the current demands for thinner, lighter, and more reliable electronic devices while simultaneously providing conductivity, cushioning protection, and safety.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a conductive foam with buffering and protective functions that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: A conductive foam with cushioning and protective function includes: a foam body, a first protective plate, a second protective plate, and a buffer body; the foam body has a layered structure, comprising a substrate, a conductive layer, and a flame-retardant layer from the inside out; the first protective plate and the second protective plate are respectively disposed on both sides of the foam body, and the first protective plate, the second protective plate, and the foam body are all connected by the buffer body; a connecting plate is provided on the foam body, the connecting plate is engaged with an installation groove on the top surface of the second protective plate, an arc-shaped protrusion is fixedly installed on the surface of the connecting plate, an arc-shaped concave body is engaged with the arc-shaped protrusion, the arc-shaped concave body is fixedly installed with the inner wall of the installation groove, and an arc-shaped rubber body is fixedly installed between the foam body and the first protective plate.

[0008] Furthermore, the arc-shaped rubber body is an elastic structure, and the arc-shaped rubber bodies are evenly spaced along the length direction of the buffer body, with a spacing of 5-10mm between two adjacent arc-shaped rubber bodies.

[0009] Furthermore, the conductive layer completely covers the outer surface of the substrate, and the flame-retardant layer completely covers the outer surface of the conductive layer; and the thickness of the conductive layer is 0.1-0.3 mm, and the thickness of the flame-retardant layer is 0.2-0.5 mm.

[0010] Furthermore, the arc-shaped protrusion and the arc-shaped concave body are adapted in shape and size, and the arc-shaped protrusion can be embedded in the arc-shaped concave body to form a locking fit.

[0011] Furthermore, the conductive layer is made of nickel-plated copper foil or conductive cloth, and the volume resistivity of the conductive layer is ≤1Ωcm.

[0012] Furthermore, the flame-retardant layer is made of flame-retardant epoxy resin or flame-retardant polyurethane, and the oxygen index of the flame-retardant layer is ≥28%, which meets the UL94V-0 flame-retardant standard.

[0013] Furthermore, both the arc-shaped protrusion and the arc-shaped concave body are made of rubber.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The first protective plate and the second protective plate of the present invention are respectively connected to both sides of the foam body through a buffer body. The arc-shaped rubber body between the foam body and the first protective plate can undergo elastic deformation to absorb external impact energy. At the same time, the connecting plate of the foam body is engaged with the mounting groove of the second protective plate. The arc-shaped protrusion on the connecting plate is adapted to engage with the arc-shaped concave body on the inner wall of the mounting groove, which can not only stabilize the connection, but also further disperse the impact force, thereby forming effective protection for the foam body and improving the overall impact resistance.

[0020] like Figures 1 to 4 As shown, this utility model relates to a conductive foam with buffer protection function, including: foam body 1, first protective plate 2, second protective plate 3 and buffer body 4.

[0021] The foam body 1 has a layered structure, consisting of a substrate 10, a conductive layer 11, and a flame-retardant layer 12 from the inside out. The flame-retardant layer 12 is made of flame-retardant epoxy resin or flame-retardant polyurethane, and its oxygen index is ≥28%, meeting the UL94V-0 flame-retardant standard. The conductive layer 11 completely covers the outer surface of the substrate 10, and the flame-retardant layer 12 completely covers the outer surface of the conductive layer 11. The thickness of the conductive layer 11 is 0.1-0.3mm, and it is made of nickel-plated copper foil or conductive cloth. The volume resistivity of the conductive layer 11 is ≤1Ω・cm, and the thickness of the flame-retardant layer 12 is 0.2-0.5mm.

[0022] The first protective plate 2 and the second protective plate 3 are respectively disposed on both sides of the foam body 1, and the first protective plate 2, the second protective plate 3 and the foam body 1 are all connected by a buffer body 4.

[0023] A connecting plate 6 is provided on the foam body 1. The connecting plate 6 is engaged with the mounting groove 7 opened on the top surface of the second protective plate 3. An arc-shaped protrusion 8 is fixedly installed on the surface of the connecting plate 6. An arc-shaped concave body 9 is engaged with the arc-shaped protrusion 8. The arc-shaped concave body 9 is fixedly installed with the inner wall of the mounting groove 7. The shape and size of the arc-shaped protrusion 8 and the arc-shaped concave body 9 are compatible. The arc-shaped protrusion 8 can be embedded in the arc-shaped concave body 9 to form a locking fit. Both the arc-shaped protrusion 8 and the arc-shaped concave body 9 are made of rubber. An arc-shaped rubber body 5 is fixedly installed between the foam body 1 and the first protective plate 2. The arc-shaped rubber body 5 is an elastic structure and is evenly spaced along the length of the buffer body 4. The distance between two adjacent arc-shaped rubber bodies 5 is 5-10mm.

[0024] When in use, the conductive foam with cushioning and protection function has the foam body 1 as the core structure, which adopts a layered design from the inside out, consisting of a substrate 10, a conductive layer 11, and a flame-retardant layer 12. The conductive layer 11 is made of nickel-plated copper foil or conductive cloth and completely covers the substrate 10 with a thickness of 0.1-0.3mm to ensure that its volume resistivity is ≤1Ω・cm and achieve stable conductivity. The flame-retardant layer 12 is covered on the outside of the conductive layer 11 with a thickness of 0.2-0.5mm. It is made of flame-retardant epoxy resin or flame-retardant polyurethane material with an oxygen index ≥28% to meet the UL94V-0 flame-retardant standard and play a role in fire protection. The foam body 1 has a first protective plate 2 and a second protective plate 3 respectively set on both sides. They are connected to the foam body 1 through a buffer body 4. When subjected to external impact, the arc-shaped rubber body 5 fixed between the foam body 1 and the first protective plate 2 (evenly distributed at 5-10mm intervals along the length of the buffer body 4 and is an elastic structure) will undergo elastic deformation to initially absorb the impact energy. At the same time, the connecting plate 6 on the foam body 1 and the mounting groove 7 on the top surface of the second protective plate 3 form a snap-fit. The rubber arc-shaped protrusion 8 on the surface of the connecting plate 6 is embedded in the rubber arc-shaped concave body 9 on the inner wall of the mounting groove 7. This not only ensures the connection stability between the second protective plate 3 and the foam body 1, but also further disperses the impact force through the cooperation of the arc-shaped protrusion 8 and the arc-shaped concave body 9. Finally, it achieves the synergistic effect of "conductivity-flame retardancy-buffering protection", ensuring that while ensuring conductivity, the overall protection capability is improved through multi-layer buffer structure and flame retardant design.
