[0044] Please refer to Figures 1 to 13 As shown, the present utility model discloses a conductive sheet 100, which comprises a skeleton 1 and an elastic component 2 fixed to the skeleton 1.

[0045] In the illustrated embodiment of the present utility model, the skeleton 1 comprises a first substrate 11 and a second substrate 12 fixed on the first substrate 11. The first substrate 11 is provided with a first surface 111 (for example, the upper surface), and the second substrate 12 is provided with a second surface 121 (for example, the lower surface) opposite to the first surface 111.

[0046] In the illustrated embodiment of the present utility model, the first substrate 11 is a metal substrate (for example, a steel frame structure) to provide better structural strength. The first substrate 11 is provided with a surrounding frame 112 and a filling space 113 located within the frame 112. In the illustrated embodiment of the present utility model, the filling space 113 penetrates through the first substrate 11 along the first direction A1-A1 (for example, the up-down direction). The surrounding frame 112 is beneficial to ensuring the structural strength.

[0047] In the illustrated embodiment of the present utility model, the second substrate 12 is a soft glue film, and glue is provided on the second substrate 12. The first substrate 11 and the second substrate 12 are fixed together by the glue. Of course, those skilled in the art can understand that the first substrate 11 and the second substrate 12 can also be fixed together by other means, and the present utility model will not elaborate on this.

[0048] The second substrate 12 is provided with a plurality of slots 122 penetrating the second substrate 12 along the first direction A1 - A1, and the slots 122 communicate with the filling space 113.

[0049] The elastic component 2 includes an elastomer 21 and a plurality of conductive elements 22 embedded in the elastomer 21. In an embodiment of the present utility model, the elastomer 21 is a silicone elastomer, that is, the elastomer 21 is made of silicone, so that it has a certain elastic deformation ability.

[0050] The plurality of conductive elements 22 include a first signal element S1, a second signal element S2, and a plurality of ground elements G. The first signal element S1 and the second signal element S2 form a differential signal pair DP for transmitting high-frequency signals. The plurality of ground elements G are discretely arranged around the differential signal pair DP to improve the shielding effect and the quality of signal transmission. In other words, there is a gap between any two adjacent ground elements G among the plurality of ground elements G arranged around the differential signal pair DP, and the elastomer 21 fills the gap and is connected into a whole, which is beneficial to improving the overall structural strength of the elastic component 2.

[0051] In the illustrated embodiment of the present utility model, each conductive element 22 includes a first docking surface 221 exposed on the first surface 111 along the first direction A1 - A1 and a second docking surface 222 exposed on the second surface 121 along the first direction A1 - A1. The first docking surface 221 is configured to abut against the first conductive member 31 of the first docking module 3, and the second docking surface 222 is configured to abut against the second conductive member 41 of the second docking module 4, so that the first conductive member 31 and the second conductive member 41 are electrically connected through the conductive element 22. In other words, the conductive element 22 acts like a transfer function.

[0052] The elastic component 2 is filled in the filling space 113 and the slots 122. The elastomer 21 is fixed to the second substrate 12 by the glue.

[0053] Please refer to Figure 12As shown, in the illustrated embodiment of the present utility model, the first signal element S1 includes a plurality of first conductors 23, and the plurality of first conductors 23 are dispersed in the elastomer 21. Please refer to Figure 13 As shown, when the plurality of first conductors 23 are subjected to forces F1, F2 along the first direction A1 - A1, they approach each other and form a first conduction path.

[0054] Similarly, please refer to Figure 12 As shown, the second signal element S2 includes a plurality of second conductors 24, and the plurality of second conductors 24 are dispersed in the elastomer 21. Please refer to Figure 13 As shown, when the plurality of second conductors 24 are subjected to forces F1, F2 along the first direction A1 - A1, they approach each other and form a second conduction path.

[0055] Those skilled in the art can understand that in the illustrated embodiment of the present utility model, although the plurality of first conductors 23 are dispersed in the elastomer 21, the plurality of first conductors 23 are not evenly dispersed in the elastomer 21. On the contrary, the plurality of first conductors 23 are aggregated around the first signal element S1, which is conducive to forming the first conduction path when subjected to external force extrusion. In addition, the positions of the plurality of first conductors 23 correspond to the positions of the first conductive members 31 of the first docking module 3.

[0056] Similarly, in the illustrated embodiment of the present utility model, although the plurality of second conductors 24 are dispersed in the elastomer 21, the plurality of second conductors 24 are not evenly dispersed in the elastomer 21. On the contrary, the plurality of second conductors 24 are aggregated around the second signal element S2, which is conducive to forming the second conduction path when subjected to external force extrusion. In addition, the positions of the plurality of second conductors 24 correspond to the positions of the second conductive members 41 of the second docking module 4.

[0057] Specifically, in the illustrated embodiment of the present utility model, the first conductor 23 is a spherical conductor and is dispersed in the elastomer 21, and the second conductor 24 is a spherical conductor and is dispersed in the elastomer 21. When the first conductor 23 is subjected to forces F1, F2 along the first direction A1 - A1, on the one hand, the first conductors 23 approach and contact each other along the first direction A1 - A1, and on the other hand, they move along the second direction A2 - A2 (for example, radial directions V1, V2). The first direction A1 - A1 is perpendicular to the second direction A2 - A2. The change of the second conductor 24 when subjected to forces F1, F2 along the first direction A1 - A1 is the same as that of the first conductor 23, and the present utility model will not elaborate further.

[0058] Please refer to Figure 9 and Figure 10 As shown, the first docking module 3 includes a first insulating body 32 and a plurality of first conductive members 31 provided on the first insulating body 32. The first docking module 3 is provided with a first grounding portion 33. Preferably, the first grounding portion 33 is provided on the first insulating body 32. The relative positional relationship between the first conductive member 31 and the first grounding portion 33 can be flexibly adjusted as needed. For example, the lower end surface of the first conductive member 31 is flush with the lower end surface of the first grounding portion 33, or the lower end surface of the first conductive member 31 protrudes from the lower end surface of the first grounding portion 33, or the lower end surface of the first grounding portion 33 protrudes from the lower end surface of the first conductive member 31. Of course, those skilled in the art can understand that the first docking module 3 can be an electrical connector or a circuit board.

[0059] Similarly, the second docking module 4 includes a second insulating body 42 and a plurality of second conductive members 41 provided on the second insulating body 42. The second docking module 4 is provided with a second grounding portion 43. Preferably, the second grounding portion 43 is provided on the second insulating body 42. The relative positional relationship between the second conductive member 41 and the second grounding portion 43 can be flexibly adjusted as needed. For example, the upper end surface of the second conductive member 41 is flush with the upper end surface of the second grounding portion 43, or the upper end surface of the second conductive member 41 protrudes from the upper end surface of the second grounding portion 43, or the upper end surface of the second grounding portion 43 protrudes from the upper end surface of the second conductive member 41. Of course, those skilled in the art can understand that the second docking module 4 can be an electrical connector or a circuit board.

[0060] The first docking module 3 and the second docking module 4 are respectively located on both sides (for example, the upper and lower sides) of the conductive sheet 100, wherein the first grounding portion 33 of the first docking module 3 and the second grounding portion 43 of the second docking module 4 are configured to be in electrical contact with the grounding element G of the conductive sheet 100; the first conductive member 31 abuts against the first docking surface 221 of the conductive element 22; the second conductive member 41 abuts against the second docking surface 222 of the conductive element 22. Finally, the first conductive member 31 and the second conductive member 41 are electrically connected through the conductive element 22. Of course, those skilled in the art can understand that during the process of the first docking module 3 and the second docking module 4 abutting against the conductive sheet 100, the elastomer 21 will be subjected to an external force and undergo compressive deformation, which is beneficial to absorbing the flatness error of the contact member.

[0061] The present utility model also discloses a manufacturing method of the aforementioned conductive sheet 100, which includes:

[0062] Providing a skeleton 1, the skeleton 1 is provided with a filling space 113 and a plurality of slotted openings 122 communicating with the filling space 113;

[0063] Providing a melt of an elastomer 21 and a plurality of conductive elements 22, the melt being in a fluid state;

[0064] Filling the melt into the filling space 113 and the slotted openings 122;

[0065] Heating the melt to cure it.

[0066] Specifically, in the illustrated embodiment of the present utility model, the skeleton 1 includes a first substrate 11 and a second substrate 12. The first substrate 11 is pre-cut into a required shape and size according to the designed dimensions by using an etching or laser cutting process. A part of the material is removed by the laser cutting process to form the slotted openings 122. The slotted openings 122 are at a certain distance from the first signal element S1 and the second signal element S2, and will not restrict the compressive deformation of the first signal element S1 and the second signal element S2 in the first direction A1-A1.

[0067] The second substrate 12 is provided with an adhesive (for example, a solid adhesive), having a specific bonding ability, to bond with the first substrate 11 together to form the skeleton 1. The second substrate 12 is also bonded to the elastomer 21 through the adhesive, serving to fix the elastomer 21.

[0068] The material of the elastomer 21 is a medium-elasticity material, which is used to absorb the flatness error of the contact member. When the elastomer 21 is subjected to an external extrusion force, it will drive the conductive element 22 to move together. The shape and size of the elastomer 21 corresponding to the slot 122 match the slot 122. The elastomer 21 is first melted with the conductive element 22 in a liquid form, and then through a certain high temperature, the elastomer 21 is transformed from a liquid state to a solid state to fix the conductive element 22. Preferably, the first docking surface 221 and the second docking surface 222 of the conductive element 22 are flush with the first surface 111 and the second surface 121 respectively. Of course, those skilled in the art can understand that in other embodiments of the present invention, the first docking surface 221 of the conductive element 22 can also be slightly lower than the first surface 111, and the second docking surface 222 of the conductive element 22 is slightly higher than the second surface 121. In other words, the conductive element 22 is located between the first surface 111 and the second surface 121. When the conductive sheet 100 is docked with the first docking module 3 and the second docking module 4, the elastomer 21 is compressed by an external extrusion force. At this time, the first docking surface 221 and the second docking surface 222 of the conductive element 22 can also be in contact with the first conductive member 31 of the first docking module 3 and the second conductive member 41 of the second docking module 4 respectively to achieve electrical conduction.

[0069] In an embodiment of the present invention, the conductive element 22 is a special spherical alloy ion conductor.

[0070] In some embodiments of the present invention, the dielectric constant DK of the material of the elastomer 21, where 1.8 ≤ DK ≤ 3.2. The elastomer 21 can provide continuous working elasticity for the conductive element 22.

[0071] In some embodiments, the conductive element 22 is composed of a number of tiny metal ions and some special solid glue mixed together, where the proportion of metal ions in the conductive element 22 is greater than or equal to 70%.

[0072] Those skilled in the art can understand that there may be a certain flatness error between the lower end surface of the first grounding portion 33 of the first docking module 3 and the lower end surface of the first conductive member 31. Therefore, there may be a risk of signal transmission interruption between the lower end surface of the first conductive member 31 and the first docking surface 221 of the conductive element 22. Similarly, there may be a certain flatness error between the upper end surface of the second grounding portion 43 of the second docking module 4 and the upper end surface of the second conductive member 41. Therefore, there may be a risk of signal transmission interruption between the upper end surface of the second conductive member 41 and the second docking surface 222 of the conductive element 22. Therefore, a device that can both transmit signals and absorb the height unevenness error of the signal contact points is needed. And the conductive sheet 100 of the present utility model just meets this requirement.

[0073] Compared with the prior art, the conductive sheet 100, the connection assembly and the manufacturing method of the conductive sheet of the present utility model include an elastic assembly 2, and the elastic assembly 2 includes an elastic body 21 and a plurality of conductive elements 22 embedded in the elastic body 21. The plurality of conductive elements 22 include a first signal element S1, a second signal element S2 and a plurality of grounding elements G, wherein the first signal element S1 and the second signal element S2 form a differential signal pair DP. The plurality of grounding elements G are discretely arranged around the differential signal pair DP, thereby improving the shielding effect. Each conductive element 22 includes a first docking surface 221 exposed to the first surface 111 along the first direction A1-A1 and a second docking surface 222 exposed to the second surface 121 along the first direction A1-A1; the first docking surface 221 is configured to abut against the first conductive member 31 of the first docking module 3, and the second docking surface 222 is configured to abut against the second conductive member 41 of the second docking module 4. When the first docking module 3 and the second docking module 4 abut against the conductive sheet 100, the elastic body 21 undergoes elastic deformation due to being squeezed to absorb the flatness error, thereby improving the contact reliability between the conductive element 22 and the first conductive member 31 and the second conductive member 41.

[0074] In addition, compared with the prior art, the installation size of the conductive sheet 100 of the present utility model is more compact, greatly saving the space size of the high-frequency electrical connection structure. The size of the conductive sheet 100 of the present utility model along the first direction A1-A1 is smaller, greatly reducing the loss on the high-frequency signal transmission path. The conductive sheet 100 of the present utility model has a wider application scenario and can be applied to various application scenarios of high-frequency signal transmission and is suitable for connection structures with high-density layouts.

[0075] The above embodiments are only used to illustrate the present utility model and do not limit the technical solutions described in the present utility model. The understanding of the present utility model should be based on those skilled in the relevant technical field. Although this specification has described the present utility model in detail with reference to the above embodiments, those of ordinary skill in the art should understand that those skilled in the relevant technical field can still make modifications or equivalent replacements to the present utility model. All technical solutions and their improvements that do not depart from the spirit and scope of the present utility model shall be covered within the scope of the claims of the present utility model.
