[0036] Electronic devices, such as wearable devices such as smart bracelets and smart watches, as well as electronic devices such as mobile phones and tablets, need to have a certain level of waterproof performance to avoid problems such as rusting of components, connection failure or short circuit when used in a water environment. However, the metal shell of the electronic device is prone to sealing failure during the process of establishing electrical connection between the antenna and the electrostatic protection components inside the electronic device.

[0037] The present disclosure provides an electrical connection mechanism. Figure 1 is a schematic diagram of a top view of an electrical connection mechanism in an exemplary embodiment of the present disclosure, Figure 2 is a schematic diagram of a three-dimensional exploded structure of an electrical connection mechanism in an exemplary embodiment of the present disclosure, Figure 3 is a schematic cross-sectional structure diagram of an electrical connection mechanism in an exemplary embodiment of the present disclosure, Figure 4 is a partial cross-sectional structural diagram of an electronic device in an exemplary embodiment of the present disclosure, Figure 5 is a partial cross-sectional structural diagram of an electronic device in another exemplary embodiment of the present disclosure, Figure 6is a schematic cross-sectional structure diagram of an electronic device in an exemplary embodiment of the present disclosure, such as Figure 1-Figure 6 As shown, Figure 2 , Figure 3 , Figure 6 The dashed arrow in the middle may represent the first direction, and the electrical connection mechanism 1 includes a first conductive body 11 and a second conductive body 12. The first conductive body 11 includes a first electrical connection portion 111 and an assembly portion 112 arranged along the first direction, and an outer sidewall 1121 of the assembly portion 112 is provided with a sealing structure 113. In the first direction, the second conductive body 12 is elastically connected to the first conductive body 11, and the second conductive body 12 includes a second electrical connection portion 121 protruding from one end of the assembly portion 112 away from the first electrical connection portion 111, and the projection of the assembly portion 112 and the second conductive body 12 is located within the contour projection of the sealing structure 113.

[0038] Since the above-mentioned electrical connection mechanism 1 includes a first conductive body 11 and a second conductive body 12 elastically connected to the first conductive body 11 in the first direction, the second electrical connection part 121 of the second conductive body 12 is in a tight state with the metal shell 221 or other components of the electronic device 2, which can improve the stability of the electrical connection mechanism 1 during the conductive connection process. The outer wall 1121 of the assembly part 112 of the first conductive body 11 is provided with a sealing structure 113, so that when the electrical connection mechanism 1 is applied to the electronic device 2, it can be sealed with the hole 2221 of the electronic device 2 through the sealing structure 113, thereby improving the overall waterproof performance of the electronic device 2. The above-mentioned electrical connection mechanism 1 has a compact design, reasonable mechanical distribution, can stably achieve electrical connection, and can be applied to the narrow assembly space of small electronic devices 2. And after the standardized size, it can be entrusted to a third-party professional manufacturer for batch production in advance, with stable quality, which helps to achieve convenient and efficient assembly.

[0039] It should be noted that the first direction may be the axial direction of the electrical connection mechanism 1 , and the electrical connection mechanism 1 is assembled and plugged into the hole 2221 on the electronic device 2 along the axial direction to achieve installation.

[0040] In the above embodiments, the assembly relationship between the second conductive body 12 and the first conductive body 11 can have various forms. For example, the second conductive body 12 can be assembled at one end of the first conductive body 11 away from the first electrical connection portion 111 to simplify the structure of the first conductive body 11 and the second conductive body 12, and improve the convenience of assembling the second conductive body 12 and the first conductive body 11. Alternatively, the first conductive body 11 can be provided with an assembly hole 1122 for accommodating and assembling the second conductive body 12, so as to optimize the structural layout of the electrical connection mechanism 1 and reduce the space occupied. Alternatively, a receiving hole 123 can also be provided in the second conductive body 12 for accommodating and assembling the first conductive body 11, which can also achieve the effect of optimizing the structural layout of the electrical connection mechanism 1 and reducing the space occupied.

[0041] In some embodiments, the assembly portion 112 may be provided with an assembly hole 1122, which forms an assembly opening at one end of the assembly portion 112 away from the first electrical connection portion 111, and at least a portion of the second conductive body 12 is movably accommodated in the assembly hole 1122 from the assembly opening to reduce the length of the electrical connection mechanism 1 in the first direction, which helps to reduce the overall size of the electrical connection mechanism 1, so that the electrical connection mechanism 1 can be applied to the narrow assembly space of a small electronic device 2.

[0042] The manner in which the second conductive body 12 is elastically connected to the first conductive body 11 in the first direction and the connection position can also be realized in a variety of forms. For example, the second conductive body 12 and the first conductive body 11 are elastically connected by respectively abutting against structures formed by elastic materials such as conductive silicone. Alternatively, the second conductive body 12 and the first conductive body 11 are elastically connected by respectively connecting to two ends of the spring that can produce relative displacement. Alternatively, the second conductive body 12 and the first conductive body 11 are elastically connected through a spring. When the second conductive body 12 and the first conductive body 11 are elastically connected through a spring, one end of the spring can be connected to one of the assembly portion 112 and the first electrical connection portion 111, and the other end of the spring is connected to the second conductive body 12.

[0043] In some embodiments, the electrical connection mechanism 1 may further include an elastic member 13, one end of the elastic member 13 along the elastic deformation direction is connected to the bottom of the assembly hole 1122, and the other end is connected to the second conductive body 12, so as to provide an assembly and deformation space for the elastic member 13 through the assembly hole 1122, and avoid the elastic member 13 causing an excessive increase in the overall size of the electrical connection mechanism 1. For example, when the elastic member 13 is a spring, the spring is assembled in the assembly hole 1122, one end of the spring is connected to the bottom of the assembly hole 1122, and the other end of the spring is connected to the second conductive body 12. The material of the spring may be metal.

[0044] In other embodiments, a receiving hole 123 may be provided on a side of the second conductive body 12 facing the first conductive body 11 to assemble and position the elastic member 13 , further reducing the impact of the assembly of the elastic member 13 on the overall size of the electrical connection mechanism 1 .

[0045] In the above embodiment, the assembly hole 1122 may include a first limiting portion 1125 disposed near the assembly opening, and the second conductive body 12 includes a second limiting portion 122 abutting against the first limiting portion 1125 in the first direction, so as to limit the range of motion of the second conductive body 12 in the assembly hole 1122, and prevent the second conductive body 12 from coming out of the assembly hole 1122 during the movement relative to the first conductive body 11. The second conductive body 12 may be assembled to the assembly hole 1122 by riveting, so as to form abutment and limiting between the second limiting portion 122 and the first limiting portion 1125.

[0046] It should be noted that the assembly portion 112 and the second conductive body 12 may form a columnar structure through the outer surface, respectively, to facilitate the installation and use of the first conductive body 11 and the second conductive body 12. The cross-sectional shape of the assembly portion 112 and the second conductive body 12 perpendicular to the first direction may be circular, rectangular, other polygonal or other irregular shapes, and the present disclosure is not limited thereto.

[0047] The second electrical connection portion 121 may be a section of the second conductive body 12 protruding from the assembly hole 1122 , and an outer surface of the second electrical connection portion 121 may be gold-plated to obtain a desired conductive effect.

[0048] The first electrical connection portion 111 may be a plate-shaped structure disposed at one end of the assembly portion 112 , and a projection of the first electrical connection portion 111 in the first direction may cover the assembly portion 112 to improve the convenience of conductive connection.

[0049] In some embodiments, the sealing structure 113 may be a rubber ring sleeved on the outer side wall 1121 of the assembly portion 112. The projections of the assembly portion 112 and the second conductive body 12 are located within the contour projection of the rubber ring, so that when the electrical connection mechanism 1 is assembled in the hole 2221 at the corresponding position of the electronic device 2, the electrical connection mechanism 1 and the hole 2221 are sealed in the entire circumferential direction through the interference fit between the rubber ring and the inner wall of the hole 2221.

[0050] The outer side wall 1121 of the assembly portion 112 may be provided with a first groove structure 1123 for fixing the rubber ring. The rubber ring is assembled in the first groove structure 1123 , and at least a portion of the rubber ring protrudes from the first groove structure 1123 .

[0051] It should be noted that the rubber ring can be a fluororubber rubber ring, which can achieve a high-strength waterproof sealing effect. The waterproof level is suitable for the IP68 waterproof standard of 3C products and the 5-20ATM waterproof standard of the watch industry.

[0052] In some embodiments, the outer wall 1121 of the assembly portion 112 is further provided with an assembly structure 114, which is arranged along the first direction on a side of the sealing structure 113 away from the first electrical connection portion 111, so that the electrical connection mechanism 1 can be fixedly assembled at a corresponding position of the electronic device 2 through the assembly structure 114.

[0053] In one embodiment, the assembly structure 114 may be a snap ring sleeved on the outer side wall 1121 of the assembly portion 112, so as to achieve fixed assembly through the deformation formed in the circumferential direction at the disconnection notch of the snap ring and the portion protruding from the outer side wall 1121. The outer side wall 1121 of the assembly portion 112 may be provided with a second groove structure 1124, and the snap ring is fixedly assembled in the above-mentioned second groove structure 1124.

[0054] A third groove structure 2222 may be provided at the corresponding hole 2221 of the electronic device 2. When the assembly structure 114 passes through the hole 2221, it is deformed due to the extrusion of the inner wall of the hole 2221, causing the outer diameter to become smaller. When reaching the third groove structure 2222, the retaining ring restores the deformation, causing the outer diameter to increase to match the third groove structure 2222, and then is snap-fitted and fixed to the third groove structure 2222.

[0055] The clamping ring can be fixedly assembled at one end of the assembly portion 112 away from the first electrical connection portion 111 to improve assembly convenience while preventing the clamping ring from affecting the assembly and function of the sealing structure 113 .

[0056] And / or, in another embodiment, if Figure 7-Figure 10 As shown, the assembly structure 114 may be a threaded structure disposed on the outer side wall 1121 of the assembly portion 112 , so as to realize assembly and fixation of the electrical connection mechanism 1 and the electronic device 2 through the threaded structure.

[0057] The sealing structure 113 and the threaded structure may be distributed along the first direction on the outer side wall 1121 of the assembly portion 112 to improve assembly convenience while preventing the retaining ring from affecting the assembly and function of the sealing structure 113 .

[0058] The present disclosure further provides an electronic device 2, such as Figure 3-Figure 6 , Figure 9-10 As shown, the electronic device 2 includes a device body 21, a shell 22 and the above-mentioned electrical connection mechanism 1, and the device body 21 is assembled in the shell 22. The shell 22 includes a metal shell 221 and a frame structure 222 located inside the metal shell 221, the frame structure 222 is provided with a hole 2221, the first conductive body 11 is assembled in the hole 2221, and the sealing structure 113 is sealed with the inner wall of the hole 2221, the first electrical connection part 111 is connected to the device body 21, and the second electrical connection part 121 is abutted against the metal shell 221.

[0059] Since the electrical connection mechanism 1 includes a first conductive body 11 and a second conductive body 12 elastically connected to the first conductive body 11 in a first direction, the second electrical connection portion 121 of the second conductive body 12 is in a tight state with the metal housing 221 or other components of the electronic device 2, which can improve the stability of the electrical connection mechanism 1 during the conductive connection process. The outer wall 1121 of the assembly portion 112 of the first conductive body 11 is provided with a sealing structure 113, so that when the electrical connection mechanism 1 is applied to the electronic device 2, it can be sealed with the hole 2221 of the electronic device 2 through the sealing structure 113, preventing water or other liquids from entering the interior of the electronic device 2 from the gap 23 between the metal housing 221 and the frame structure 222 and the hole 2221, thereby improving the overall waterproof performance of the electronic device 2.

[0060] In some embodiments, a positioning hole 2211 may be provided on the side of the metal shell 221 facing the frame structure 222 , and at least a portion of the second conductive body 12 is assembled in the positioning hole 2211 , thereby being used to achieve positioning and assembly of the metal shell 221 and the electrical connection mechanism 1 .

[0061] It should be noted that the electronic device 2 may be a mobile phone, a tablet computer, a vehicle-mounted terminal, a medical terminal, a wearable device, etc., and the present disclosure does not limit this. The electrical connection mechanism 1 may be used to realize electrical connection scenarios such as antenna grounding and ESD (Electro-Static discharge) grounding of the metal housing 221 of the electronic device 2.
