[0002] In the prior electrical connection mechanism, it is common to use welding to make electrical connection such as grounding of electronic devices. For example, in the assembly of PCB board of electronic devices such as consumer electronics, workers need to weld ground wires one by one to metal shielding covers or frames. Such traditional process has many limitations. The welding process itself has a high temperature, which can easily damage heat-sensitive components, especially under the trend of miniaturization of microelectronic devices. And to achieve reliable connection, auxiliary connecting parts are often needed, such as special welding sheets, fastening screws and insulating washers used in conjunction with ground welding points. Further, the welding process is difficult to automate, such as the welding process of grounding still relies on manual operation, which seriously restricts the improvement of production capacity. At the same time, using permanent or semi-permanent fixation such as welding for electrical connection will make the electrical connection part difficult to disassemble, which increases the maintenance cost.
[0003] Therefore, there is an urgent need to provide an electrical connection mechanism and an electronic device scheme to realize flexible and rapid installation of the electrical connection mechanism, improve the production efficiency of electrical connection, and save costs.

[0030] The embodiments of the present disclosure provide an electrical connection mechanism and electronic device, by making the second connecting piece have a first limiting part, a second limiting part, and a positioning groove formed between the two, and making the first connecting piece clamped in the positioning groove by means of the elastic connecting arm, and being limited by the first limiting part and the second limiting part. Thus, the electrical connection between different external components can be quickly and conveniently achieved, and the production and maintenance costs are reduced.
[0031] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
[0032] Referring to Figures 1 to 3 wherein Figure 1 An exemplary perspective view of an electrical connection mechanism according to some embodiments of the present disclosure is shown, Figure 2 An exemplary perspective view of a first connecting piece of an electrical connection mechanism according to some embodiments of the present disclosure is shown, Figure 3 An exemplary perspective view of a second connecting piece of an electrical connection mechanism according to some embodiments of the present disclosure is shown.
[0033] As shown in the drawings, an electrical connection mechanism according to some embodiments of the present disclosure includes a first connecting piece 10 and a second connecting piece 20. The first connecting piece 10 includes two elastic connecting arms 11 arranged at intervals on one side thereof. The second connecting piece 20 includes a first limiting portion 21 and a second limiting portion 22 arranged at intervals opposite to each other, and a positioning groove 24 recessed between the first limiting portion 21 and the second limiting portion 22. The first connecting piece 10 and the second connecting piece 20 are respectively capable of being fixed and electrically connected with different external components 90. The two elastic connecting arms 11 are matched with the positioning groove 24 in shape, so that the first connecting piece 10 can clamp the second connecting piece 20, and the first connecting piece 10 and the second connecting piece 20 are electrically connected.
[0034] Specifically, the first connecting piece 10 is made of a conductive material such as copper, or has an outer surface made of a conductive material such as copper. The two elastic connecting arms 11 are arranged at intervals opposite to each other, and are made of a material such as copper sheet having elasticity. The two elastic connecting arms 11 are capable of elastically moving away from or approaching each other, so that they can elastically clamp the second connecting piece 20. The one side of the first connecting piece 10 is provided with the elastic connecting arms 11, and the other side thereof is capable of being fixed and electrically connected with a wire or the like first external component 91.
[0035] The second connecting piece 20 is also made of a conductive material such as copper, or has an outer surface made of a conductive material. The second connecting piece 20 is formed to have the first limiting portion 21 and the second limiting portion 22 opposite to each other. The first limiting portion 21 and the second limiting portion 22 are both substantially formed in a plate shape, and are arranged parallel to each other. The positioning groove 24 recessed between the first limiting portion 21 and the second limiting portion 22 is matched with the shape and size of the two elastic connecting arms 11 of the first connecting piece 10 in shape and size, so that the two elastic connecting arms 11 of the first connecting piece 10 can extend into the positioning groove 24 of the second connecting piece 20, and be limited by the first limiting portion 21 and the second limiting portion 22. At the same time, the side of the second limiting portion 22 away from the first limiting portion 21 is used to be fixed and electrically connected with a circuit board or the like second external component 92. Thus, after the first connecting piece 10 and the second connecting piece 20 are joined, the elastic connecting arms 11 are limited by the first limiting portion 21 and the second limiting portion 22 in the direction of intervals between the first limiting portion 21 and the second limiting portion 22, and the two elastic connecting arms 11 clamp the second connecting piece 20 from both sides of the second connecting piece 20 respectively, so that the first connecting piece 10 is stably connected with the second connecting piece 20, and the risk of poor contact or even connection failure caused by relative movement of a device electrically connected with the first connecting piece 10 or the second connecting piece 20 is reduced.
[0036] The first limiting part 21 and the second limiting part 22 are provided with a connecting column 23 with a circular cross section, and the two elastic connecting arms 11 are clamped on both sides of the connecting column 23. Thus, when connecting the first connecting piece 10 to the second connecting piece 20, it can be installed at any angle. Moreover, when the first external part 91 and / or the second external part 92 connected to the first connecting piece 10 and the second connecting piece 20 move relatively, if the first connecting piece 10 is subjected to a certain torque, the two elastic connecting arms 11 of the first connecting piece 10 can rotate a certain angle relative to the circular connecting column 23, thereby offsetting the torque and further reducing the risk of poor contact or even connection failure due to the movement of the external part 90.
[0037] Those skilled in the art can understand that, although the above describes a scheme in which the second connecting piece 20 is provided with a connecting column 23 with a circular cross section, and the connecting column 23 connects the first limiting part 21 and the second limiting part 22, the present disclosure does not limit the specific structure of the second connecting piece 20, as long as it can be fixed and electrically connected with the first connecting piece 10 in shape. For example, in some embodiments not shown, the second connecting piece 20 includes a connecting column 23 with a polygonal or elliptical cross section, and the two elastic connecting arms 11 of the first connecting piece 10 are also provided with an inner surface that matches the shape of the connecting column 23. Thus, when the first connecting piece 10 is fixed to the second connecting piece 20, the elastic connecting arms 11 and the connecting column 23 can be connected in a rotation-proof manner by shape matching. Thus, when the external part 90 moves relatively, the connection angle and position between the first connecting piece 10 and the second connecting piece 20 can remain unchanged, improving the stability of the electrical connection.
[0038] Referring to Figure 2 , Figure 4 and Figure 5 , Figure 4 the second connecting piece of the electrical connection mechanism of some embodiments of the present disclosure is shown, Figure 5An exemplary top view of the first connecting member of the electrical connecting mechanism of some embodiments of the present disclosure is shown, in which a first external component 91 connected with the first connecting member 10 is shown in dashed line. For the dimensions of the first connecting member 10 and the second connecting member 20, the distance between the closest parts of the two elastic connecting arms 11 should be smaller than the diameter of the connecting column 23, so that the elastic connecting arms 11 can clamp the connecting column 23. While the axial length of the connecting column 23 should be greater than or equal to the distance between the two opposite end faces of the elastic connecting arms 11 along the axial direction of the connecting column 23, so that the elastic connecting arms 11 can extend into the space between the first limiting part 21 and the second limiting part 22 and clamp. In this embodiment, the two elastic connecting arms 11 are arranged obliquely relative to each other, so that the minimum distance between the distal ends of the two elastic connecting arms 11 is smaller than the maximum distance between the proximal ends. This oblique arrangement of the elastic connecting arms 11 can continuously counteract the external force applied to the first connecting member 10 and the second connecting member 20, even if the external force causes the two connecting members to move away from each other, thereby improving the stability of the connection between the two connecting members.
[0039] In this embodiment, the diameter of the connecting column 23 is defined as a first size D1. Preferably, the first size D1 is in the range of 2 to 2.5 mm, and the distance between the closest parts of the two elastic connecting arms 11 is a second size W1, which is in the range of 1 to 1.5 mm, so that the second size is smaller than the first size. The axial length of the connecting column 23 is a first length H1, which is in the range of 1 to 1.5 mm, and the distance between the two opposite end faces of the elastic connecting arms 11 along the axial direction of the connecting column 23 is a second length H2, which is in the range of 0.5 to 1 mm, where the second length is smaller than the first length. Alternatively, the axial first length H1 of the connecting column 23 is 1 mm, and the distance between the two opposite end faces of the elastic connecting arms 11 along the axial direction of the connecting column 23 is a second length H2 of 0.8 mm. In this way, the elastic connecting arms 11 of the first connecting member 10 can be stably clamped around the connecting column 23, and the installation is more convenient and fast. At the same time, the above size settings make the electrical connecting mechanism particularly suitable for use in small and micro electronic devices such as circuit boards, so that it can complete the electrical connection with the external component 90 without enlarging the overall size of the electronic device.
[0040] The first limiting portion 21 is formed in a plate shape, and the plate size and shape should be at least partially larger than the cross section of the connecting column 23 to limit the elastic connecting arm 11 clamped on the connecting column 23. In this embodiment, the first limiting portion 21 is formed in a circular plate shape, and the diameter is the third size D2. The third size D2 is larger than the first size D1, and the third size D2 is 3-4 mm, and optionally, the third size D2 is 3.1 mm. Thus, the outer periphery of the first limiting portion 21 can protrude outside the connecting column 23 to limit the elastic connecting arm 11. Since the first limiting portion 21 is formed in a circular shape, even if the external component 90 moves relative to the second connecting member 20 after the first connecting member 10 is connected with the external component 90 such as a wire, the external component 90 will not interfere with the outer edge of the first limiting portion 21, thereby reducing the wear caused by the movement of the external component 90. In addition, the side of the first limiting portion 21 towards the second limiting portion 22 is provided with an arc-shaped outer edge 211. The arc-shaped outer edge 211 is gradually curved and formed in an arc shape from the outer periphery of the first limiting portion 21 towards the second limiting portion 22, so as to guide the elastic connecting arm 11 into the positioning groove 24 during installation, making the installation more convenient, and further reducing the wear between the external component 90 such as a wire and the outer periphery of the first limiting portion 21.
[0041] Referring again to Figure 5 In some embodiments, the distal ends of the two elastic connecting arms 11 are respectively folded towards each other to form a folded portion 111, and the opposite side of the two folded portions 111 is provided with a transition arc surface 112. When the first connecting member 10 has an elastic connecting arm 11 made of metal or the like, the folded portion 111 can be formed by bending the distal ends of the elastic connecting arm 11 away from each other by the metal or the like. After bending, the transition arc surface 112 can be formed on the inner side of the folded portion 111. The transition arc surface 112 formed by the folded portion 111 is convenient to process, and is especially suitable for small and micro-sized electrical connecting members. During the connection of the first connecting member 10 and the second connecting member 20, the transition arc surface 112 can reduce the wear of the distal end of the elastic connecting arm 11 when it contacts the connecting column 23, avoid damaging the surface of the connecting column 23, and improve the conductivity after connection.
[0042] In addition, in Figure 5In the shown embodiment, an arc-shaped connecting section 12 is arranged between the two elastic connecting arms 11, and the central angle of the arc-shaped connecting section 12 is greater than 180°. The diameter of the arc-shaped connecting section 12 is greater than the distance between the closest ends of the two elastic connecting arms 11, so that after the first connecting piece 10 is connected to the second connecting piece 20, the arc-shaped connecting section 12 can surround the connecting column 23 at an angle greater than 180°, and the closest ends of the distal ends of the two elastic connecting arms 11 lock the connecting column 23. In this way, the contact area between the first connecting piece 10 and the second connecting piece 20 after connection can be increased, and the conduction effect is improved. At the same time, the connecting column 23 is supported by the arc-shaped connecting section 12 when it is subjected to force in any circumferential direction, so that the connecting column 23 is locked relative to the first connecting piece 10, thereby achieving stable retention of the first connecting section.
[0043] According to the electric connecting mechanism of the embodiments of the present disclosure, the second connecting piece is provided with a first limiting portion, a second limiting portion, and a positioning groove formed by concave between the two, and the first connecting piece is clamped in the positioning groove by means of the elastic connecting arms, and is limited by the first limiting portion and the second limiting portion. Thus, the electric connection between different external components can be quickly and conveniently achieved, and the use of additional pressing pieces for limiting is avoided, the production and installation costs are reduced, and the electric connecting mechanism can be easily disassembled and assembled, thereby reducing the maintenance costs.
[0044] In addition, referring to Figure 6 and Figure 7 , Figure 6 an exemplary perspective view of an electronic device according to some embodiments of the present disclosure is shown, Figure 7 an exemplary cross-sectional view of an electronic device according to some embodiments of the present disclosure is shown. The electronic device 200 includes an electric connecting mechanism 100 according to various embodiments of the present disclosure and an electronic device 300, and the second connecting piece 20 is fixedly arranged on the electronic device 300 and is electrically connected to the electronic device 300. The electronic device 300 is an electronic component such as a circuit board, and the second connecting piece 20 is fixedly connected to the electric connecting portion on the electronic device 300 by means of welding or the like, and the first connecting piece 10 is electrically connected to the first external component 91 such as a wire. Thus, after the first connecting piece 10 and the second connecting piece 20 are fixedly and electrically connected, the electric connection between the external component 90 and the electronic device 300 can be quickly and conveniently achieved.

Numerous changes, substitutions and equivalents can occur to those skilled in the art without departing from the spirit and scope of the disclosure.
