[0034] The exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. If several embodiments exist, features in these embodiments may be combined with each other without conflict. When the description refers to the drawings, unless otherwise stated, the same numbers in different drawings represent the same or similar elements. The descriptions in the following exemplary embodiments do not represent all embodiments consistent with the present invention; rather, they are merely examples of apparatuses, products, and / or methods consistent with some aspects of the present invention as set forth in the claims.

[0035] The terminology used in this invention is for the purpose of describing particular embodiments only and is not intended to limit the scope of protection of this invention. The singular forms “a,” “the,” or “the” used in the specification and claims of this invention are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0036] Please refer to Figures 1 to 12This application discloses a connection structure 100, which includes a conductor 1, an insulating body 2, and a plate-shaped conductor 3. The conductor 1 has a connection hole 101, and the plate-shaped conductor 3 is embedded in the insulating body 2. The plate-shaped conductor 3 includes a base 31, and the base 31 has a protrusion 32. At least a portion of the protrusion 32 protrudes from the insulating body 2 and is disposed within the connection hole 101 and is electrically connected to the conductor 1. This arrangement makes the connection between the plate-shaped conductor 3 and the conductor 1 more stable and less likely to detach and affect the circuit conduction.

[0037] Please refer to Figures 1 to 12 In one embodiment of this application, conductor 1 is a circuit board with a connection hole 101. The protrusion 32 of the plate-shaped conductor 3 is disposed in the connection hole 101. This reduces the assembly step difference between the plate-shaped conductor 3 and the circuit board, thereby reducing the occurrence of circuit breakage due to poor soldering between the plate-shaped conductor 3 and the circuit board.

[0038] In another embodiment of this application, conductor 1 is a metal plate with a connection hole 101. The protrusion 32 of the plate-shaped conductor 3 is welded to the hole wall of the connection hole 101 so that the plate-shaped conductor 3 is electrically connected to the metal plate.

[0039] In another embodiment of this application, the conductor 1 is a metal-embedded molded plastic part, and a connection hole 101 is provided in the metal part of the conductor 1. The protrusion 32 of the plate-shaped conductor 3 is welded to the hole of the connection hole 101 so that the metal-embedded molded plastic part is electrically connected to the plate-shaped conductor 3.

[0040] In one embodiment of this application, please refer to Figures 3 to 6 The plate-shaped conductor 3 includes a first plate-shaped conductive sheet 301 and a second plate-shaped conductive sheet 302, both of which are sheet-shaped. The first plate-shaped conductive sheet 301 includes a first base 3011 and two first protrusions 3012 disposed at both ends of the first base 3011. The second plate-shaped conductive sheet 302 includes a second base 3021 and two second protrusions 3022 disposed at both ends of the second base 3021. The first base 3011 and the second base 3021 are embedded in the insulating body 2, and the two first protrusions 3012 and the two second protrusions 3022 respectively protrude outward from the insulating body 2. The first plate-shaped conductive sheet 301, the second plate-shaped conductive sheet 302, and the insulating body 2 are integrally injection molded, which facilitates positioning and assembly.

[0041] In this embodiment, the protrusion 32 and the base 31 are integrally die-cast. Specifically, the two first protrusions 3012 and the first base 3011 are integrally die-cast, and the two second protrusions 3022 and the second base 3021 are integrally die-cast. This improves the overall structural strength of the first plate-shaped conductive sheet 301 and the second plate-shaped conductive sheet 302, thereby improving conductivity. In other embodiments, the two first protrusions 3012 are welded to the first base 3011, and the two second protrusions 3022 are welded to the second base 3021; ​​this is not limited here.

[0042] Please refer to Figure 12 In this embodiment, the protrusion 32 is cylindrical. Specifically, after the cylindrical first protrusion 3012 and second protrusion 3022 are inserted into the connection hole 101 on the conductor 1, the first protrusion 3012 and the second protrusion 3022 respectively fit against the hole wall of the connection hole 101. By adding tin into the connection hole 101, the liquid tin flows into the gap between the first protrusion 3012, the second protrusion 3022 and the hole wall of the connection hole 101, thereby enabling the first protrusion 3012 and the second protrusion 3022 to connect and conduct with the connection hole 101 respectively.

[0043] In another embodiment, the protrusion 32 is frustum-shaped. Specifically, the bottom area of ​​the frustum-shaped first protrusion 3012 and second protrusion 3022 is larger than the end area. In this case, the wall of the connecting hole 101 is inclined. After the frustum-shaped first protrusion 3012 and second protrusion 3022 are respectively inserted into the connecting hole 101 on the conductor 1, the first protrusion 3012 and second protrusion 3022 respectively fit against the wall of the connecting hole 101. By adding tin into the connecting hole 101, the liquid tin flows into the gap between the first protrusion 3012, second protrusion 3022 and the wall of the connecting hole 101, thereby enabling the first protrusion 3012 and second protrusion 3022 to connect and conduct with the connecting hole 101 respectively.

[0044] Please refer to Figures 2 to 4 as well as Figure 9The wall of the connecting hole 101 is provided with a metal ring 13, and the protrusion 32 contacts the metal ring 13. Specifically, the metal ring 13 includes an annular portion 131 and two abutting portions 132 disposed at both ends of the annular portion 131. The annular portion 131 is fitted against the wall of the connecting hole 101, and the abutting portions 132 are connected to the upper and lower surfaces of the conductor 1 on the periphery of the connecting hole 101. The conductor 1 includes a first surface 11 and a second surface 12 that are vertically opposite each other. The annular portion 131 is disposed in the connecting hole 101 and fits against the wall of the connecting hole 101. The two abutting portions 132 abut against the first surface 11 and the second surface 12 respectively, so that the metal ring 13 can be fixedly engaged with the connecting hole 101. The first protrusion 3012 and the second protrusion 3022 are inserted into the connecting hole 101 and contact the annular portion 131 of the metal ring 13. By adding tin into the connecting hole 101, the liquid tin flows into the gap between the hole walls of the first protrusion 3012, the second protrusion 3022, and the annular portion 131, thereby enabling the first protrusion 3012 and the second protrusion 3022 to connect and conduct electricity with the metal ring 13, respectively. By providing the metal ring 13, the contact area between the hole wall of the connecting hole 101 and the first protrusion 3012 and the second protrusion 3022 can be increased, thereby improving the stability of electrical conductivity.

[0045] The surface of the protrusion 32 is plated with gold, silver, or tin. This allows the plate-shaped conductor 3 to be soldered to the conductor 1, thus enabling circuit conduction.

[0046] Please refer to Figures 1 to 4 This application also discloses a button structure 200, which includes a connecting structure 100, an elastic metal member 210, and a button 220. The button 220 is disposed on the side of the insulating body 2 away from the conductor 1, with at least a portion of its base 31 exposed on the surface of the insulating body 2 near the conductor 1, a protrusion 32 protruding from the surface of the insulating body 2 near the conductor 1, and the elastic connector 210 disposed between the button 220 and the insulating body 2.

[0047] As one embodiment of this application, the insulating body 2 includes a top surface 21 and a bottom surface 22 disposed opposite to each other. A first base 3011 and a second base 3021 are exposed on the top surface 21 from the insulating body 2, and two first protrusions 3012 and two second protrusions 3022 protrude from the bottom surface 22 from the insulating body 2. An elastic metal member 210 is disposed on the top of the insulating body 2, and a button 220 is disposed on the top of the elastic metal member 210. When the button 220 applies force to the elastic metal member 210, the elastic metal member 210 deforms under force and contacts the base 31, that is, the elastic metal member 210 deforms under force and contacts the first base 3011 and the second base 3021. This enables the first plate-shaped conductive sheet 301, the second plate-shaped conductive sheet 302, and the conductor 1 to form a circuit. When button 220 is released, the elastic metal part 210 loses pressure and releases its elastic force, and the elastic metal part 210 returns to its state before deformation. Then the circuit between the first plate-shaped conductive sheet 301, the second plate-shaped conductive sheet 302 and the conductor 1 is broken.

[0048] Please refer to Figures 1 to 4 The insulating body 2 has a recessed portion 211 with a groove 212 inside. An electrical contact portion 33 is provided on the base 31, extending into the groove 212 and exposed on the surface of the insulating body 2. An elastic metal member 210 is disposed within the recessed portion 211. Specifically, the top surface 21 of the insulating body 2 has a recessed portion 211 with a groove 212 inside. The base 31 is embedded in the insulating body 2, and the electrical contact portion 33 on the base 31 extends into the groove 212, with its surface exposed in the groove. The elastic metal member 210 is disposed within the recessed portion 211, covering the groove 212. That is, the electrical contact portion 33 is located directly below the elastic metal member 210. The elastic metal member 210 is bent, and without external pressure, it arches towards the button 220 during a single bend.

[0049] As one embodiment of this application, there are multiple plate-shaped conductors 3, and each plate-shaped conductor 3 has an electrical contact portion 33 on its base 31. The multiple electrical contact portions 33 extend alternately into the groove 212. Specifically, as shown... Figures 5 to 7The first base 3011 has a first electrical contact 3013 on its side, which is disposed between two first protrusions 3012. The second base 3021 has two second electrical contacts 3023 on its side, which are disposed between two second protrusions 3022. The bottom surface 22 of the insulating body 2 has four through slots 221, and the two first protrusions 3012 and the two second protrusions 3022 protrude outward from their respective through slots 221. The four through slots 221 are arranged in a rectangular shape on the bottom surface 22. In the embodiment of this application, the first electrical contact 3013 and the two second electrical contacts 3023 are arranged face to face, with the first electrical contact 3013 disposed between the two second electrical contacts 3023. At least a portion of the first electrical contact 3013 and at least a portion of the second electrical contact 3023 are exposed from the groove 212 into the recess 211. In this embodiment, the elastic metal element 210 is a bowl-shaped spring sheet, and it is disposed in the recessed portion 211. When the button 220 applies force to the elastic metal element 210, the elastic metal element 210 deforms under the force and comes into contact with the first electrical contact portion 3013 and the two second electrical contacts 3023, thereby making the circuit between the first plate-shaped conductive sheet 301, the second plate-shaped conductive sheet 302, and the conductor 1 conductive. When the button 220 is released, the elastic metal element 210 loses pressure and releases its elastic force, returning to its state before deformation, thus breaking the circuit between the first plate-shaped conductive sheet 301, the second plate-shaped conductive sheet 302, and the conductor 1. An insulating film 230 is also provided between the button 220 and the elastic metal element 210 to provide insulation between them.

[0050] Please refer to Figure 1 This application also discloses an electronic device, which may be a Bluetooth headset, smart bracelet, smart glasses, etc., and is not limited thereto. The electronic device includes a button structure 200 and a housing. The button structure 200 is disposed within the housing, and the housing has mounting holes. The button 220 is disposed within the mounting holes. This arrangement improves the stability of the connection between the plate-shaped conductor 3 and the conductor 1, avoids circuit breaks due to poor soldering, thereby improving the product yield of the electronic device and reducing its maintenance costs.

[0051] In summary, this application discloses a connection structure 100, which includes a conductor 1, an insulating body 2, and a plate-shaped conductor 3. The conductor 1 has a connection hole 101, the insulating body 2 is disposed on one side of the conductor 1, and the plate-shaped conductor 3 is embedded in the insulating body 2. The plate-shaped conductor 3 includes a base 31, and the base 31 has a protrusion 32. At least a portion of the protrusion 32 protrudes from the insulating body 2 and is disposed within the connection hole 101 and electrically connected to the conductor 1. This arrangement makes the connection between the plate-shaped conductor 3 and the conductor 1 more stable and less prone to detachment, thus affecting circuit conductivity.
