The first housing 110 and the second housing 120 are bonded by a first colloid 143182. The circuit board 130 is connected to the electrical connection component 140 of the second housing 120, and then the electrical connection component 140 of the second housing 120 is connected to the first housing 110, forming an electrical connection structure of the electronic device 100, so that the electronic device 100 has the function of antenna signal transmission.

Through the conductivity of the metal powder 141 and the waterproofness of the colloid 143, the metal powder 141 and the colloid 143 are mixed and arranged, and used as the electrical connection component 140 inside the electronic device 100.

At the same time, because the mixture of the metal powder 141 and the colloid 143 contains epoxy glue, the gap has a waterproof function, and thus the electrical connection component 140 does not need to be separately provided with a seal, which simplifies the structure of the electronic device 100 and improves the reliability of the electronic device 100.

[0045] Furthermore, the electrical connection component 140 defined in this embodiment can realize the electrical connection function between the antenna 102 of the first shell 110 and the internal circuit board 130 through the plant design system (PDS) printing process and the hole filling process, and design a specific connection structure on the plastic and hardware, and has good electrical performance and waterproof performance.

[0047] In this embodiment, a first through hole 122 is provided on the side wall of the second housing 120, and the electrical connection component 140 is provided on the second housing 120. The first connection portion 142 of the electrical connection component 140 blocks the first through hole 122, further simplifying the sealing structure of the electronic device 100 and improving the sealing effect of the electronic device 100. The end of the first connection portion 142 facing the outside of the second housing 120 is electrically connected to the first housing 110, and the end of the first connection portion 142 facing the inside of the second housing 120 is electrically connected to the circuit board 130. The first housing 110 is electrically connected to the circuit board 130 through the first connection portion 142, so that the antenna signal is transmitted to the circuit board 130, which reduces the difficulty of the manufacturing process of the electronic device 100 and makes the product more competitive. At the same time, the first through hole 122 is blocked by the mixture of the metal powder 141 and the colloid 143. Since the mixture of the metal powder 141 and the colloid 143 is waterproof, the first through hole 122 is blocked to form a waterproof structure, which further simplifies the sealing structure of the electronic device 100, improves the sealing effect, and improves the waterproof performance of the electronic device 100. In some embodiments of the present application, optionally, the electrical connection component 140 also includes: a second connection portion 144, the second connection portion 144 is arranged along the inner side wall of the second shell 120, extends from the first through hole 122 to the circuit board 130, and the second connection portion 144 is connected to the first connection portion 142 and is electrically connected to the circuit board 130.

[0048] In this embodiment, the electrical connection component 140 also includes a second connection portion 144, which is arranged along the inner wall of the second shell 120. The first connection portion 142 is electrically connected to the circuit board 130 through the second connection portion 144, so that the antenna signal is transmitted to the circuit board 130. At the same time, the second connection portion 144 is arranged along the inner wall of the second shell 120, extending from the first through hole 122 to the circuit board 130, and the second connection portion 144 is connected to the first connection portion 142, so that the position of the second connection portion 144 is fixed, and then the circuit board 130 can be assembled to the second shell 120. The electrical connection between the circuit board 130 and the electrical connection component 140 can be achieved, thereby simplifying the assembly process of the electronic device 100, reducing the assembly difficulty of the electronic device 100, and improving the assembly efficiency of the electronic device 100.

[0049] Specifically, the technical solution defined in this application can use a silver paste perfusion device, using a small needle (about ) and injection air pressure to pour silver paste into the first through hole 122, filling it flush with the inner wall of the second shell 120, and baking it at about 100°C for the first curing, which is the first connecting part 142. Then use the silver paste pad printing equipment to transfer the silver paste to the inner wall of the second shell 120 to form an L-shaped structure, which is the second connecting part 144. Then perform a second baking at about 100°C. The first connecting part 142 and the silver paste-shaped pad printed circuit board 130 are cured again to form a stable solid silver column and silver layer to form a connecting circuit. The second connecting part 144 can be produced and manufactured through a printing process, and the first connecting part 142 and the second connecting part 144 are cured and connected to form an electrical connecting part 140, which further reduces the difficulty of the manufacturing process of the electronic device 100, reduces production costs, and improves production efficiency.

[0050] At the same time, because the metal powder 141 and the colloid 143 are mixed with waterproof performance, the installation gap between the first shell 110 and the second shell 120 is waterproofly sealed while the first shell 110 is electrically connected to the first connecting portion 142. The metal powder 141 and the colloid 143 are mixed and poured into the first through hole 122 of the second shell 120, and the first through hole 122 is waterproofly sealed while conducting electricity, forming a waterproof structure, and improving the waterproof performance of the electronic device 100.

[0051] According to some embodiments of the present application, Figure 5 and Figure 6 As shown, optionally, the area of ​​the cross section of the first through hole 122 is a first area; the first area first decreases and then increases from the outside of the second shell 120 to the inside of the second shell 120.

The first through hole 122 structure is first reduced and then increased, so that the electrical connection component 140 has a limited position in the first through hole 122. Even when the electronic device 100 vibrates, the electrical connection component 140 will not be displaced relative to the first through hole 122 due to the structural characteristics of the first through hole, and the electrical connection will not be interrupted, further ensuring the stability of the antenna signal transmission of the electronic device 100.

After the first shell 110 and the second shell 120 are bonded together, the first through holes 122 are blocked by the first shell 110 and become blind holes, which is convenient for pouring the mixture of metal powder 141 and colloid 143, thereby simplifying the assembly process of the electronic device 100 and improving production efficiency.

[0054] According to some embodiments of the present application, Figure 7a to Figure 7h As shown, optionally, the first through hole 122 is in the first direction (such as Figure 6 The cross-section in the direction indicated by the arrow B in the figure is one of the following shapes or a combination thereof: rectangle, triangle, trapezoid, rhombus, polygon, circle and ellipse; wherein the first direction is from the side of the first through hole close to the first shell to the side of the first through hole close to the inside of the second shell, or the first direction is from the side of the first through hole close to the inside of the second shell to the side of the first through hole close to the first shell.

[0055] In this embodiment, the cross section of the first through hole 122 in the first direction is one of the following shapes or a combination thereof: rectangle, triangle, trapezoid, rhombus, polygon, circle and ellipse, which reduces the difficulty of the manufacturing process of the electronic device 100, reduces the production cost and improves the production efficiency. The first direction points from the side of the first through hole close to the first shell to the side of the first through hole close to the inside of the second shell, or the first direction points from the side of the first through hole close to the inside of the second shell to the side of the first through hole close to the first shell.

[0056] Specifically, Figure 6 and Figure 7a As shown, in the first direction, the first through hole may be rectangular, and the first area is the same from the outside of the second shell 120 to the inside of the second shell 120; Figure 6 and Figure 7b As shown, the first through hole may be a triangle, the first area gradually decreases from the outer side of the second shell 120 to the inner side of the second shell 120, and the tip is electrically connected to the second connection portion 144; Figure 6 and Figure 7c As shown, the first through hole may be a triangle, the first area gradually increases from the outer side of the second shell 120 to the inner side of the second shell 120, and the tip is electrically connected to the first connecting portion 142; Figure 6 and Figure 7d As shown, the first through hole may be a trapezoid, the first area decreases from the outer side of the second shell 120 to the inner side of the second shell 120, and the first area of ​​the outer side of the second shell 120 is greater than the first area of ​​the inner side of the second shell 120; Figure 6 and Figure 7eAs shown, the first through hole may be a trapezoid, the first area increases from the outer side of the second shell 120 to the inner side of the second shell 120, and the first area of ​​the outer side of the second shell 120 is smaller than the first area of ​​the inner side of the second shell 120; Figure 6 and Figure 7f As shown, the first through hole can be a quadrilateral, the first area increases first and then decreases from the outside of the second shell 120 to the inside of the second shell 120, one end of the quadrilateral is electrically connected to the first connecting portion 142, and the other end is electrically connected to the second connecting portion 144; Figure 6 and Figure 7g As shown, the first through hole can be a hexagon, and the first area increases from the outer side of the second shell 120 to the inner side of the second shell 120, then remains unchanged, and then decreases. One end of the hexagon is electrically connected to the first connecting portion 142, and the other end is electrically connected to the second connecting portion 144; Figure 6 and Figure 7h As shown, the first through hole may be a combination of a rectangle and an ellipse, and the first area first decreases and then increases from the outer side of the second shell 120 to the inner side of the second shell 120 .

[0057] According to some embodiments of the present application, Figure 8 , Fig. 9 and Fig.10 As shown, optionally, the first shell 110 is provided with a first blind hole 112, the opening 104 of the first blind hole 112 faces the second shell 120, and the first blind hole 112 is connected to the first through hole 122; the electrical connection component 140 also includes a third connection portion 146, the third connection portion 146 is arranged in the first blind hole 112, and is connected to the first connection portion 142.

[0058] In this embodiment, the first housing 110 is provided with a first blind hole 112, so that the third connection part 146 is inserted into the first blind hole 112 and electrically connected to the first housing 110, so as to prevent the third connection part 146 from being displaced in the first blind hole 112 when the electronic device 100 is subjected to severe vibration, thereby ensuring the transmission of antenna signals of the electronic device 100 and improving the stability of the electronic device 100. The opening 104 of the first blind hole 112 faces the second housing 120, and the first blind hole 112 is connected to the first through hole 122, so that the electrical connection contact area between the third connection part 146 and the first connection part 142 is larger, the electrical connection contact strength is more stable, and the stability of the electrical connection structure of the electronic device 100 is improved.
