Description

Technical Field

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

[0002] Conductive foam is a composite functional material that combines conductivity and elasticity. Its core advantage lies in the combination of excellent conductivity and soft cushioning. It can effectively shield electromagnetic interference and dissipate static electricity. At the same time, it is lightweight, easy to process, and can be cut into specific shapes. It is widely used in the electronics field, such as filling gaps in equipment housings to prevent electromagnetic leakage, protecting sensitive components from static electricity, and serving as flexible grounding pads. It is a key material that balances electromagnetic protection, shock absorption and sealing, and convenient installation.

[0003] However, in the process of using conductive foam, which consists of foam strips and conductive sleeves covering the surface of the foam strips, the only way to improve the shock absorption performance of conductive foam is to increase the thickness of the foam strips. This can easily result in the conductive foam being too large and taking up internal space in electronic devices, thus reducing its practicality.

[0004] Therefore, a multi-layer shock-absorbing and conductive foam is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of simply increasing the thickness of the foam strip when it is necessary to improve the shock absorption performance of conductive foam, which can easily lead to excessively large conductive foam volume and occupy internal space of electronic equipment. Therefore, a multi-layer shock-absorbing conductive foam is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer shock-absorbing conductive foam, comprising a first foam strip and a second foam strip, wherein a conductive sleeve is fixedly fitted on the surface of the first foam strip and the second foam strip, and a modified rubber strip is fixedly connected between the first foam strip and the second foam strip, wherein the modified rubber strip is fixedly connected to the conductive sleeve.

[0007] The effect achieved by the above components is as follows: by setting the first foam strip, the second foam strip, the conductive sleeve and the modified rubber strip, the first foam strip and the second foam strip can provide basic elastic support for the conductive sleeve. The modified rubber strip, with its own elastic recovery, forms an elastic complement with the first foam strip and the second foam strip, realizing multi-layer buffering. While improving the shock absorption performance of the conductive foam, it avoids the conductive foam from becoming too large, thereby reducing the space occupied by the conductive foam in the internal space of the electronic device.

[0008] Preferably, a plurality of first buffer balls are fixedly connected inside the first foam strip, and a plurality of second buffer balls are fixedly connected inside the second foam strip.

[0009] The effect achieved by the above components is that the first and second buffer balls can absorb external impact energy through their own deformation, forming a further buffer protection.

[0010] Preferably, the outer wall of the conductive sleeve is bonded with double-sided adhesive tape, and a release film is adhered to the surface of the double-sided adhesive tape.

[0011] The effect achieved by the above components is that the double-sided tape is used to quickly fix the electronic device, and the release film on its surface can protect the adhesiveness of the tape.

[0012] Preferably, a tension film is fixedly connected to the surface of the release film.

[0013] The effect achieved by the above components is that the pull film fixedly connected to the release film surface makes it easy to tear off the release film.

[0014] Preferably, the upper surface of the double-sided tape is lower than the upper surface of the conductive sleeve.

[0015] The effect achieved by the above components is as follows: by making the upper surface of the double-sided tape lower than the upper surface of the conductive sleeve, when fixing the conductive sleeve, the first cotton strip needs to be squeezed to make the double-sided tape contact the electronic device. Therefore, the first cotton strip will deform, thereby better adhering to the electronic device and avoiding poor contact.

[0016] Preferably, the modified rubber strip has a through hole, and the surfaces of the first foam strip, the conductive sleeve, and the modified rubber strip have guide holes, which are connected to the through hole.

[0017] The effect achieved by the above components is that the through holes opened in the modified rubber strip can form a through airflow channel with the guide holes opened on the surface of the first foam strip and the conductive sleeve, which facilitates airflow for heat dissipation.

[0018] Preferably, a plurality of first protrusions are fixedly connected to the side of the modified rubber strip near the first foam strip, and the first protrusions are fixedly connected to the first foam strip. A plurality of second protrusions are fixedly connected to the side of the modified rubber strip near the second foam strip, and the second protrusions are fixedly connected to the second foam strip.

[0019] The effect achieved by the above components is that the first protrusion and the second protrusion are fixed to the first foam strip and the second foam strip respectively, which can enhance the stability of the interlayer connection.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a first foam strip, a second foam strip, a conductive sleeve, and a modified rubber strip, the first and second foam strips can provide basic elastic support for the conductive sleeve. The modified rubber strip, with its own elastic recovery, forms an elastic complement to the first and second foam strips, achieving multi-layer buffering. This improves the shock absorption performance of the conductive foam while avoiding excessive volume of the conductive foam, thereby reducing the space occupied inside the electronic device.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] like Figures 1-4As shown, this utility model provides a multi-layer shock-absorbing conductive foam, including a first foam strip 1 and a second foam strip 2. A conductive sleeve 3 is fixedly sleeved on the surface of the first foam strip 1 and the second foam strip 2. A modified rubber strip 4 is fixedly connected between the first foam strip 1 and the second foam strip 2. The modified rubber strip 4 is fixedly connected to the conductive sleeve 3. By setting the first foam strip 1, the second foam strip 2, the conductive sleeve 3 and the modified rubber strip 4, the first foam strip 1 and the second foam strip 2 can provide basic elastic support for the conductive sleeve 3. The modified rubber strip 4, with its own elastic recovery, forms an elastic complement with the first foam strip 1 and the second foam strip 2, realizing multi-layer buffering. While improving the shock absorption performance of the conductive foam, it avoids the conductive foam from being too large, thereby reducing the space occupied by the conductive foam in the internal space of electronic equipment.

[0026] like Figures 2-4 As shown, several first buffer balls 5 are fixedly connected inside the first foam strip 1, and several second buffer balls 6 are fixedly connected inside the second foam strip 2. The first buffer balls 5 and the second buffer balls 6 can absorb external impact energy through their own deformation, forming further buffer protection. Double-sided tape 7 is glued to the outer wall of the conductive sleeve 3. Release film 8 is pasted on the surface of the double-sided tape 7. The double-sided tape 7 is used to achieve quick fixation with electronic equipment. The release film 8 on its surface can protect the adhesiveness of the tape. A pull film 13 is fixedly connected to the surface of the release film 8. The pull film 13 fixedly connected to the surface of the release film 8 makes it easy to tear off the release film 8. The upper surface of the double-sided tape 7 is lower than the upper surface of the conductive sleeve 3. By making the upper surface of the double-sided tape 7 lower than the upper surface of the conductive sleeve 3, when fixing the conductive sleeve 3, the first foam strip 1 needs to be squeezed to make the double-sided tape 7 contact the electronic equipment. Therefore, the first foam strip 1 will deform, so that it can better adhere to the electronic equipment and avoid poor contact.

[0027] like Figures 3-4 As shown, the modified rubber strip 4 has a through hole 9, and the surfaces of the first foam strip 1, the conductive sleeve 3, and the modified rubber strip 4 have guide holes 10. The guide holes 10 are connected to the through hole 9. The through hole 9 in the modified rubber strip 4 can form a through airflow channel with the guide holes 10 on the surfaces of the first foam strip 1 and the conductive sleeve 3, which facilitates airflow for heat dissipation. Several first protrusions 11 are fixedly connected to the side of the modified rubber strip 4 near the first foam strip 1. The first protrusions 11 are fixedly connected to the first foam strip 1. Several second protrusions 12 are fixedly connected to the side of the modified rubber strip 4 near the second foam strip 2. The second protrusions 12 are fixedly connected to the second foam strip 2. The first protrusions 11 and the second protrusions 12 are fixed to the first foam strip 1 and the second foam strip 2, respectively, which can enhance the stability of the interlayer connection.

[0028] The overall working principle is as follows: the first cotton strip 1 and the second cotton strip 2 provide basic elastic support for the conductive sleeve 3; the modified rubber strip 4, with its own elastic recovery, complements the first cotton strip 1 and the second cotton strip 2, achieving multi-layer buffering; the first buffer ball 5 and the second buffer ball 6 can absorb external impact energy through their own deformation, forming further buffer protection; the first protrusion 11 and the second protrusion 12 are fixed to the first cotton strip 1 and the second cotton strip 2 respectively, which can enhance the stability of the interlayer connection; the through hole 9 opened in the modified rubber strip 4 can be aligned with the guide hole 10 opened on the surface of the first cotton strip 1 and the conductive sleeve 3. The conductive sleeve 3 forms a through-flow channel to facilitate airflow and heat dissipation. The conductive sleeve 3 forms a complete conductive outer layer to ensure overall conductivity and electromagnetic shielding effect. The double-sided tape 7 is used to quickly fix it to the electronic device. The release film 8 pasted on its surface can protect the tape's adhesiveness. The pull film 13 fixedly connected to the surface of the release film 8 makes it easy to tear off the release film 8. By making the upper surface of the double-sided tape 7 lower than the upper surface of the conductive sleeve 3, when fixing the conductive sleeve 3, the first cotton strip 1 needs to be squeezed to make the double-sided tape 7 contact the electronic device. Therefore, the first cotton strip 1 will deform, so that it can better adhere to the electronic device and avoid poor contact.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
