[0027] The following refers to Figures 1-6 to describe the connecting plate 100 according to the embodiment of the first aspect of the present utility model.
[0028] As Figures 1-6 shown, the connecting plate 100 according to the embodiment of the first aspect of the present utility model includes a body 1, an elastic conductive member 2, and a conductive connecting member 3.
[0029] Specifically, a mounting hole 11 is formed on the body 1, and the mounting hole 11 penetrates the body 1 along the thickness direction of the body 1. The elastic conductive member 2 is disposed in the mounting hole 11, and on one side surface of the elastic conductive member 2 in the thickness direction of the body 1 is not lower than one side surface of the body 1. At least a part of the conductive connecting member 3 is located between the inner wall of the mounting hole 11 and the outer wall of the elastic conductive member 2.
[0030] For example, in Figures 1-6 the example, four mounting holes 11 are formed on the body 1 at intervals, and all four mounting holes 11 penetrate the thickness direction of the body 1. The conductive connecting member 3 and the elastic conductive member 2 are disposed in the mounting hole 11. With such a setting, the structure of the connecting plate 100 is simplified, the processing of the connecting plate 100 is simple, which is beneficial to reducing the cost of the connecting plate 100. The resistivity of the elastic conductive member 2 and the conductive connecting member 3 at the mounting hole 11 is lower, which is beneficial to reducing the signal loss and realizing high-speed signal transmission. In addition, the cooperation of the conductive connecting member 3 and the elastic conductive member 2 is beneficial to improving the conductive performance of the connecting plate 100, thereby facilitating the connection of the electronic components 200 on both sides in the thickness direction of the connecting plate 100.
[0031] The main body 1, the elastic conductive member 2 and the conductive connecting member 3 are detachable, which facilitates the repeated use of the connecting plate 100, is conducive to the processing and maintenance of the connecting plate 100, reduces the processing and maintenance costs of the connecting plate 100, and improves the reliability of the connecting plate 100 at the same time.
[0032] On one side surface of the elastic conductive member 2 in the thickness direction of the main body 1, it can be flush with one side surface of the main body 1, or on one side surface of the elastic conductive member 2 in the thickness direction of the main body 1, it can protrude from one side surface of the main body 1. The elastic conductive member 2 can be connected to the electrical connection points of other electronic components 200.
[0033] For example, when one side surface of the elastic conductive member 2 in the thickness direction of the main body 1 is flush with one side surface of the main body 1, the electrical connection points of the electronic component 200 can protrude from the surface of the electronic component 200, so as to realize the connection between the electrical connection points and the elastic conductive member 2; when one side surface of the elastic conductive member 2 in the thickness direction of the main body 1 protrudes from one side surface of the main body 1, the electrical connection points of the electronic component 200 can be flush with the surface of the electronic component 200, so as to realize the connection between the electrical connection points and the elastic conductive member 2.
[0034] When using the connecting plate 100 to connect the electronic components 200, compared with the traditional connector, the design freedom of the connecting plate 100 is improved. For example, it is beneficial to increase the number of signal links and improve the selectivity of the setting of the positions of the connection points.
[0035] Among them, the main body 1 is a rigid material such as a general hard board, flexible board or glass board of a PCB (Printed Circuit Board), and a substrate, etc. But it is not limited to this.
[0036] The electronic component 200 is a PCB, FPC (Flexible Printed Circuit Board), BGA (Ball Grid Array) or a chip. But it is not limited to this.
[0037] According to the connecting plate 100 of the embodiment of the present invention, by installing the elastic conductive member 2 and the conductive connecting member 3 in the mounting hole 11 of the main body 1 to realize the flow of electrical signals on both sides of the connecting plate 100, the structure of the connecting plate 100 is relatively simple, the processing difficulty of the connecting plate 100 is reduced, which is beneficial to reducing the cost of the connecting plate 100. The cooperation of the conductive connecting member 3 and the elastic conductive member 2 is beneficial to improving the conductive performance of the connecting plate 100, reducing the signal loss, and realizing high-speed signal transmission.
[0038] According to some embodiments of the present invention, refer to Figures 1-3, the conductive connection member 3 includes a first connection section 31 and two second connection sections 32. The first connection section 31 is disposed between the inner wall of the mounting hole 11 and the outer wall of the elastic conductive member 2. The two second connection sections 32 are respectively connected to both ends of the first connection section 31. Each second connection section 32 extends in a direction perpendicular to the first connection section 31 and covers a part of the surface in the thickness direction of the body 1. That is to say, the first connection section 31 extends in the thickness direction of the body 1, and the second connection section 32 extends in a direction perpendicular to the first connection section 31. Thus, each second connection section 32 can contact the corresponding electronic component 200, so that the conductive connection member 3 is used to realize the electrical connection between the connection plate 100 and at least one electronic component 200.
[0039] Further, referring to Figure 1 , the thickness of the conductive connection member 3 is H, and the extension length of each second connection section 32 is L. Wherein, H and L respectively satisfy: 2μm ≤ H ≤ 70μm, 25μm ≤ L ≤ 100μm. When H < 2μm, the thickness of the conductive connection member 3 is small, the conductive effect of the conductive connection member 3 is poor, and at the same time the structural strength of the conductive connection member 3 is small, thereby reducing the service life of the connection plate 100. Thus, by setting the thickness of the conductive connection member 3 to 2μm ≤ H ≤ 70μm, the thickness design of the conductive connection member 3 is more reasonable, that is, the conductive effect and structural strength of the conductive connection member 3 are more reasonable, and at the same time the elastic selectivity of the connection plate 100 is increased, and the applicability of the connection plate 100 is improved.
[0040] When L < 25μm, the extension length of each second connection section 32 is small, and the contact area between each second connection section 32 and the corresponding electronic component 200 is small, thereby reducing the electrical connection efficiency between the conductive connection member 3 and the corresponding electronic component 200; when L > 100μm, the extension length of each second connection section 32 is large. While each second connection section 32 satisfies the electrical connection with the corresponding electronic component 200, it is not conducive to the lightweight setting of the connection plate 100 and increases the cost of the connection plate 100. Thus, by setting the extension length of each second connection section 32 to 25μm ≤ L ≤ 100μm, the extension length design of each second connection section 32 is more reasonable, that is, while each second connection section 32 is electrically connected to the corresponding electronic component 200, it is conducive to the lightweight of the connection plate 100 and reduces the cost of the connection plate 100.
[0041] According to some embodiments of the present invention, referring to Figures 1-3, the elastic conductive member 2 includes a first conductive section 21 and at least one second conductive section 22. The first conductive section 21 is disposed in the mounting hole 11. The second conductive section 22 is connected to the first conductive section 21. The second conductive section 22 is located on the side of the first conductive section 21 away from the body 1, and the outer diameter of the second conductive section 22 is greater than the aperture of the mounting hole 11. That is to say, the elastic conductive member 2 may include a first conductive section 21 and a second conductive section 22, or the elastic conductive member 2 includes a first conductive section 21 and two second conductive sections 22. The outer diameter of the first conductive section 21 is adapted to the aperture of the mounting hole 11, and the outer diameter of the second conductive section 22 is relatively large, which is beneficial to the positioning of the elastic conductive member 2, thereby improving the use stability of the elastic conductive member 2. At the same time, the contact area between the second conductive section 22 and the corresponding electronic component 200 is increased to improve the electrical connection stability between the elastic conductive member 2 and the corresponding electronic component 200.
[0042] Further, the outer diameter of the second conductive section 22 is smaller than the outer diameter of the second connecting section 32. With such a setting, it is ensured that the second conductive section 22 is supported on the second connecting section 32, thereby ensuring the electrical connection between the second conductive section 22 and the second connecting section 32, and further improving the electrical connection stability of the connecting plate 100.
[0043] In addition, referring to Figures 1-3 , the sum of the thicknesses of the second conductive section 22 and the first connecting section 31 in the thickness direction of the body 1 is d, and the minimum distance h between the body 1 and the adjacent electronic component 200, where d and h satisfy: d ≤ h. Thus, the sum of the thicknesses of the second conductive section 22 and the first connecting section 31 is relatively reasonable, which is beneficial to giving full play to the role of the connecting plate 100, that is, enabling the end of the second conductive section 2 away from the first conductive section 21 to reliably abut against the corresponding electronic component 200, thereby improving the electrical connection stability between the connecting plate 100 and the adjacent electronic component 200.
[0044] According to other embodiments of the present invention, the elastic conductive member 2 is an elastic conductive adhesive member. The elastic conductive adhesive member combines the two characteristics of elasticity and conductivity. The elastic conductive adhesive member has elasticity after curing at normal temperature or high temperature. Therefore, using the elastic conductive adhesive as the elastic conductive member 2 is beneficial to improving the use flexibility of the elastic conductive member 2 and reducing the installation difficulty of the elastic conductive member 2 in the mounting hole 11.
[0045] The elastic conductive adhesive member includes at least one of a silica gel member, a rubber member, and an epoxy adhesive member. Among them, the elastic conductive adhesive member is suitable for uniformly distributing conductive particles such as silver-coated copper powder and nickel-coated graphite powder in at least one of silica gel, rubber, and epoxy resin, and achieving good electrical conductivity through the mutual contact and connection of the conductive particles.
[0046] The silicone parts have the advantages of heat resistance, good chemical stability, and easy processing; the rubber parts have excellent elasticity, wear resistance, weather resistance, and damping properties; the epoxy resin parts have excellent mechanical properties, adhesion properties, chemical resistance, and strength. Therefore, using at least one of the silicone parts, rubber parts, and epoxy resin parts as the elastic conductive parts is beneficial to reducing the processing difficulty of the connecting plate 100, improving the processing efficiency of the connecting plate 100, and reducing the cost of the connecting plate 100.
[0047] In some alternative embodiments, the conductive connecting member 3 includes at least one of a copper conductive member, a gold conductive member, a silver conductive member, and a copper-gilded conductive member. Among them, the copper conductive member has a low resistivity, stable conductive performance, and good mechanical properties; the gold conductive member has a low resistivity, good chemical stability, oxidation resistance, and ductility; the silver conductive member has good conductive performance, corrosion resistance, and a relatively high melting point; the copper-gilded conductive member has the excellent electrical conductivity of copper and the excellent corrosion resistance and good contact performance of gold. Therefore, using at least one of the copper conductive member, gold conductive member, silver conductive member, and copper-gilded conductive member as the conductive connecting member 3 is beneficial to ensuring the conductive performance of the conductive connecting member 3 and reducing energy loss, thereby improving the usability of the connecting plate 100.
[0048] During the actual processing, first drill the mounting holes 11 in the body 1, and use processes such as electroless copper plating and electroplating or sputtering to fabricate the conductive connecting member 3. For example, the pattern of the required mounting holes 11 can be etched out by etching, and a gold or gold-protected copper layer is plated on the upper surface of the mounting holes 11 (i.e., the conductive connecting member 3 is formed). Then, through processes such as printing or dispensing, the elastic conductive member 2 is filled in the mounting holes 11.
[0049] The electronic device (not shown in the figure) according to the second aspect embodiment of the present invention includes the connecting plate 100 according to the first aspect embodiment of the present invention as described above.
[0050] According to the electronic device of the embodiment of the present invention, by adopting the connecting plate 100, it is beneficial to improving the electrical connection stability of the electronic device and at the same time reducing the cost of the electronic device.
