Description

Technical Field

[0001] This utility model relates to the field of conductive foam technology, and in particular to a highly stable ultra-thin shock-absorbing conductive foam. Background Technology

[0002] Conductive foam refers to a type of foam in which a conductive cloth is wrapped around a flame-retardant sponge and, after a series of treatments, it has good surface conductivity. It can be easily fixed to the device that needs to be shielded with adhesive tape. Because it generally has good shielding effect and elasticity, it is widely used in electronic products such as PDP TVs, LCD monitors, LCD TVs, mobile phones, laptops, MP3 players, communication cabinets, and medical instruments, as well as in the military and aerospace fields.

[0003] Patent publication number CN218888947U discloses an ultra-thin shock-absorbing conductive foam, comprising a conductive cloth, foam, and a release film. The conductive cloth, foam, and release film are sequentially stacked and bonded together with an adhesive. The conductive cloth is a single-layer fabric woven from silver-plated polyester fibers in a two-way interlocking warp and weft pattern. The foam is a foam material with an internal pore structure prepared from a film-forming polymer. The pore size of the pore structure is a closed-cell structure of 5-200 micrometers, and the total volume of the pore structure accounts for 20-50% of the total volume of the foam. The structure is simple, consisting only of the conductive cloth, foam, and release film, allowing for a thinner profile. The conductive cloth has a uniform conductive mesh and good electromagnetic shielding performance. The pore structure of the foam provides compressibility, giving the conductive foam good elasticity, making it suitable for filling narrow gaps and providing conductive shielding, with broad application prospects.

[0004] The conductive foam described above is similar to existing conductive foams in that the conductive cloth and foam layers are generally simply bonded together with adhesive. The connection method is relatively simple, especially at the edges, which are prone to separation and lifting. Once the adhesive at the edges ages, edge peeling is very likely to occur. If it is not dealt with in time, the peeling area can easily continue to expand and affect subsequent use. Therefore, a high-stability ultra-thin shock-absorbing conductive foam is proposed to solve the above problems. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a highly stable, ultra-thin shock-absorbing and conductive foam.

[0006] The high-stability, ultra-thin shock-absorbing and conductive foam provided by this utility model adopts the following technical solution:

[0007] A high-stability ultra-thin shock-absorbing and conductive foam includes foam, a fireproof layer is bonded to the outside of the foam with an adhesive, a wear-resistant layer is bonded to the outside of the fireproof layer with an adhesive, a conductive cloth is bonded to the outside of the wear-resistant layer with an adhesive, and a stabilizing mechanism is provided on the outside of the foam.

[0008] The stabilizing mechanism includes a main rubber strip. An installation groove is formed on the foam, through which the main rubber strip passes and matches the installation groove. The main rubber strip and the foam are bonded together with adhesive. Two rubber frames are provided on the outer side of the main rubber strip. A tie rod is integrally formed between the rubber frames and the main rubber strip. A pressure plate is provided on the outside of the fireproof layer. The pressure plate sequentially passes through the conductive cloth, the fireproof layer, and the wear-resistant layer, extending into the interior of the rubber frames. A control plate is provided on one side of the rubber frames, and a positioning plate is integrally formed on one side of the control plate. The positioning plate extends into the interior of the rubber frames and passes through the pressure plate.

[0009] By adopting the above technical solution, the pressure plate is inserted from the outermost side of the conductive cloth and bonded and fixed. Then, the positioning plate is inserted from both sides again. After the positioning plate passes through the pressure plate, it achieves the locking purpose. At this time, the pressure plate can properly press the fireproof layer, wear-resistant layer and conductive cloth on the outside of the foam. The pressing force can effectively prevent the bonding parts on the outside of the foam from separating. Secondly, even if separation has occurred, the continued presence of the pressing force can further prevent the separation from spreading, which has high stability. Finally, the main rubber strip, rubber frame, tie rod, pressure plate, control plate, positioning plate and auxiliary pad are all made of rubber material, which can achieve the purpose of stability while ensuring that the elasticity during use is not affected too much.

[0010] Preferably, auxiliary pads are fixedly connected to both sides of the conductive cloth, the pressure plate passes through the auxiliary pads, and the pressure plate is bonded to the conductive cloth, auxiliary pads, fireproof layer and wear-resistant layer respectively by adhesive.

[0011] By adopting the above technical solution, the auxiliary pad serves to support the pressure plate, preventing the conductive cloth from being too soft to provide effective support for the pressure plate.

[0012] Preferably, the foam has fixing grooves on both sides, the rubber frame and the tie rod are placed inside the fixing grooves, and the rubber frame and the tie rod are bonded to the inner wall of the fixing groove with adhesive.

[0013] By adopting the above technical solution, the tie rod provides tension to the rubber frame.

[0014] Preferably, a placement groove is provided on one side of the rubber frame, the control plate is placed inside the placement groove and bonded to the inner wall of the placement groove with adhesive, and the positioning plate and the pressure plate are bonded with adhesive.

[0015] By adopting the above technical solution, the positioning plate penetrates through the pressure plate and is bonded to it, and the pressure plate maintains a stable state.

[0016] Preferably, the main rubber strip, rubber frame, tie rod, pressure plate, control plate, positioning plate and auxiliary pad are all made of rubber material.

[0017] By adopting the above technical solution and using rubber materials, the system achieves stability while ensuring that the elasticity during use is not significantly affected.

[0018] Preferably, the fireproof layer is made of fiberglass cloth, and the wear-resistant layer is made of polytetrafluoroethylene resin.

[0019] By adopting the above technical solution, the fireproof layer serves the purpose of fire prevention and heat insulation, while the wear-resistant layer serves the purpose of wear resistance.

[0020] Preferably, the fireproof layer has a thickness of 0.05 mm and the wear-resistant layer has a thickness of 0.06 mm.

[0021] By adopting the above technical solution, the wear-resistant layer is set on the outside of the fireproof layer, which can provide wear-resistant protection for the fireproof layer.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] 1. A high-stability ultra-thin shock-absorbing conductive foam, through the design of a stabilizing mechanism, inserts a pressure plate from the outermost side of the conductive cloth and fixes it with adhesive. Then, a positioning plate is inserted from both sides. After the positioning plate passes through the pressure plate, it achieves the locking purpose. At this time, the pressure plate can properly press the fireproof layer, wear-resistant layer and conductive cloth on the outside of the foam. The pressing force can effectively prevent the adhesive parts on the outside of the foam from separating. Secondly, even if separation has occurred, the continued presence of the pressing force can further prevent the separation from spreading, thus having high stability. Finally, the main rubber strip, rubber frame and other components are all made of rubber material, which can not only achieve the purpose of stability, but also ensure that the elasticity during use is not affected too much.

[0024] 2. A high-stability ultra-thin shock-absorbing conductive foam improves the bonding stability between layers. Since the main rubber strip and the rubber frame are only connected by a tie rod, there is a large gap between the main rubber strip and the rubber frame. Even when it is squeezed, the rubber frame can deform under pressure, ensuring that it can deform normally when squeezed and recover its posture by its own elasticity after the force is exhausted. Therefore, it has high compatibility. Attached Figure Description

[0033] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.

[0034] This utility model discloses a highly stable, ultra-thin shock-absorbing and conductive foam. (Refer to...) Figures 1-7 It includes foam 1, a fireproof layer 2 is bonded to the outside of foam 1 by an adhesive, a wear-resistant layer 3 is bonded to the outside of fireproof layer 2 by an adhesive, a conductive cloth 4 is bonded to the outside of wear-resistant layer 3 by an adhesive, and a stabilizing mechanism 5 is provided on the outside of foam 1.

[0035] The stabilizing mechanism 5 includes a main rubber strip 51. A mounting groove 52 is provided on the foam 1. The main rubber strip 51 passes through the mounting groove 52 and matches the mounting groove 52. The main rubber strip 51 is bonded to the foam 1 with an adhesive. Two rubber frames 53 are provided on the outside of the main rubber strip 51. A tie 54 is integrally formed between the rubber frame 53 and the main rubber strip 51. A pressure plate 55 is provided on the outside of the fireproof layer 2. The pressure plate 55 passes through the conductive cloth 4, the fireproof layer 2 and the wear-resistant layer 3 in sequence. The pressure plate 55 extends into the interior of the rubber frame 53.

[0036] A control plate 56 is provided on one side of the rubber frame 53, and a positioning plate 57 is integrally formed on one side of the control plate 56. The positioning plate 57 extends into the interior of the rubber frame 53 and passes through the pressure plate 55. The pressure plate 55 is inserted from the outermost side of the conductive cloth 4 and bonded and fixed. Then, the positioning plate 57 is inserted again from both sides. After the positioning plate 57 passes through the pressure plate 55, it achieves the locking purpose. At this time, the pressure plate 55 can properly press the fireproof layer 2, wear-resistant layer 3 and conductive cloth 4 on the outside of the foam 1. The pressing force can effectively prevent the bonding parts on the outside of the foam 1 from separating. Secondly, even if separation has occurred, the continued presence of the pressing force can further prevent the separation from spreading, which has high stability. Finally, the main rubber strip 51, rubber frame 53, tie rib 54, pressure plate 55, control plate 56, positioning plate 57 and auxiliary pad 58 are all made of rubber material, which can achieve the purpose of stability while ensuring that the elasticity during use is not affected too much.

[0037] Auxiliary pads 58 are fixedly connected to both sides of the conductive cloth 4. A pressure plate 55 passes through the auxiliary pads 58. The pressure plate 55 is bonded to the conductive cloth 4, the auxiliary pads 58, the fireproof layer 2, and the wear-resistant layer 3 with adhesive. The auxiliary pads 58 support the pressure plate 55 to prevent the conductive cloth 4 from being too soft to provide effective support for the pressure plate 55. Fixing grooves 59 are opened on both sides of the foam 1. The rubber frame 53 and the tie rod 54 are placed inside the fixing grooves 59. The rubber frame 53 and the tie rod 54 are bonded to the inner wall of the fixing groove 59 with adhesive. The tie rod 54 provides tension to the rubber frame 53. A placement groove 591 is opened on one side of the rubber frame 53. The control plate 56 is placed inside the placement groove 591 and bonded to the inner wall of the placement groove 591 with adhesive. The positioning plate 57 is bonded to the pressure plate 55 with adhesive. The positioning plate 57 passes through the pressure plate 55 and is bonded to it, keeping the pressure plate 55 in a stable state.

[0038] The main rubber strip 51, rubber frame 53, tie rod 54, pressure plate 55, control plate 56, positioning plate 57, and auxiliary pad 58 are all made of rubber material. The rubber material serves a stabilizing purpose while ensuring that the elasticity during use is not excessively affected. The fireproof layer 2 is made of fiberglass cloth, and the wear-resistant layer 3 is made of polytetrafluoroethylene resin. The fireproof layer 2 serves a fireproof and heat-insulating purpose, while the wear-resistant layer 3 serves a wear-resistant purpose. The thickness of the fireproof layer 2 is 0.05 mm, and the thickness of the wear-resistant layer 3 is 0.06 mm. The wear-resistant layer 3 is placed on the outside of the fireproof layer 2 to provide wear-resistant protection for the fireproof layer 2.

[0039] In actual operation, the fireproof layer 2 on the outside of foam 1 can serve the purpose of fireproofing and high temperature resistance, while the wear-resistant layer 3 improves the wear resistance during use. Finally, since foam 1, fireproof layer 2, wear-resistant layer 3 and conductive cloth 4 are bonded together in sequence, in order to avoid separation at the bonding edges, which may lead to peeling of the bonding surface in severe cases, a main rubber strip 51 is set inside foam 1. After applying adhesive to the pressure plate 55, it is inserted from the outermost side. After insertion, adhesive is also applied to the positioning plate 57 and control plate 56, and the control plate 56 is pressed into the placement groove 591. Then, the positioning plate 57 passes through the pressure plate 55 to fix the pressure plate 55. The clamping force applied by the pressure plate 55 can effectively prevent the bonding parts on the outside of foam 1 from separating. Secondly, even if separation has occurred, the continued presence of clamping force can further prevent the separation from spreading, thereby improving the stability during use.

[0040] Finally, while ensuring the improved bonding stability between each layer, since the main rubber strip 51 and the rubber frame 53 are only connected by the tie rod 54, there is a large gap between the main rubber strip 51 and the rubber frame 53. Even when it is squeezed, the rubber frame 53 can deform under pressure. Furthermore, since the main rubber strip 51, rubber frame 53, tie rod 54, pressure plate 55, control plate 56, positioning plate 57, and auxiliary pad 58 are all made of rubber material, they can deform and have a certain elasticity. When the pressure is released, the existence of this elastic force can also provide support for the state restoration of the foam 1, thereby ensuring high elasticity during overall use.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
