[0028] Specifically, both ends of the elastic beam 1242 are connected with the cavity wall of the receiving cavity 122, thereby increasing the stability of the elastic beam 1242 and improving the reliability of the second buckle 124, the receiving cavity 122 penetrates through the bracket 120 along the direction Z from the bracket 120 to the back cover assembly 110, the elastic beam 1242 extends along the direction perpendicular to the direction from the bracket 120 to the back cover assembly 110, that is, the extension direction X of the elastic beam 1242 is perpendicular to the direction Z from the bracket 120 to the back cover assembly 110, and the elastic beam 1242 penetrates through the receiving cavity 122, that is, the elastic beam 1242 is arranged straight relative to the receiving cavity, thereby reducing the space occupation of the second buckle 124 in the direction Z from the bracket 120 to the back cover assembly 110 and reducing the thickness of the electronic device 100.

[0029] The cross section of the accommodating cavity 122 can be circular, polygonal, or irregular, and so on.

[0035] The direction Z is the direction from the bracket 120 to the rear cover assembly 110, the direction X is the extension direction of the elastic beam 1242, and the direction Y is the direction perpendicular to the direction Z and the direction X.

[0036] As described above, by reasonably setting the size of the elastic beam 1242, the space occupied by the second buckle 124 in the electronic device 100 can be reduced.​

[0037] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , as a possible implementation, the first buckle 112 is a male buckle, the second buckle 124 is a female buckle, the number of the elastic beams 1242 is two, and the second buckle 124 further comprises at least two second limiting portions 1244, which are respectively arranged on the two elastic beams 1242.

[0045] The first limiting portion 1124 and the second limiting portion 1244 are arranged oppositely. The two elastic beams 1242 are arranged in a substantially parallel manner. During the cooperation between the first buckle 112 and the second buckle 124, when the first limiting portion 1124 and the second limiting portion 1244 are in contact, the elastic beam 1242 is elastically deformed, and after the first limiting portion 1124 passes the second limiting portion 1244, the elastic beam 1242 returns to the original state, and the second limiting portion 1244 clamps the first limiting portion 1124, thereby realizing the buckling of the first buckle 112 and the second buckle 124. Similarly, during the cooperation between the first buckle 112 and the second buckle 124, when the first limiting portion 1124 and the second limiting portion 1244 are in contact, the elastic beam 1242 is elastically deformed, and after the first limiting portion 1124 passes the second limiting portion 1244, the elastic beam 1242 returns to the original state, and the second limiting portion 1244 and the first limiting portion 1124 are separated, thereby realizing the cooperation between the first buckle 112 and the second buckle 124.

[0068] The electronic device 130 such as a flash, an antenna, an infrared light source or an electrostatic discharge device is arranged on the camera decoration piece 116 or the battery cover 114 of the rear cover assembly 110, and the connection part 132 or the grounding point of the electronic device 130 needs to be connected to the elastic contact 140 attached on the circuit board 150, so as to realize transmission of electrical signals or grounding, the top force of the elastic contact 140 is usually large, which can cause problems such as floating of the elastic contact 140, and affect the sealing of the electronic device, or reliability problems such as peeling of the rear cover assembly 110, and the first buckle 112 and the second buckle 124 adopted in the present application can resist the elastic force of the elastic contact 140 by pulling the camera decoration piece 116 and the bracket 120, so as to ensure the sealing of the electronic device 100 and the reliability of the elastic contact 140 in conducting the circuit board 150 and the electronic device 130.

[0069] The first buckle 112, the second buckle 124 and the elastic contact 140 of the electronic device 100 provided in the application are in the same area and are homologous design. The top force of the elastic contact 140 and the pulling force between the first buckle 112 and the second buckle 124 are offset to each other, there is no misalignment torque, and the stacking space of the circuit board 150 and the support 120 is saved, that is, the elastic contact 140 avoids the region and the second buckle 124 region together, avoiding the waste of excess space.

[0070] The gold finger of the connecting part 132 of the electronic device 130 is assembled in the groove 1126 of the first buckle 112, which plays a good limiting role. The camera decoration 116 is arranged synchronously with the first buckle, which ensures the position of the gold finger and good limiting in the X direction, the Y direction and the Z direction, avoiding the risk of contact misalignment, and the beam type female buckle of the second buckle 124, that is, the second buckle 124 includes the elastic beam 1242, which has a relatively simple structure and needs smaller Z direction space. Only two elastic beams 1242 are needed, the mold structure is not complex, the mold can be easily repaired, and the buckle elasticity can be optimized by adding or subtracting glue.

[0071] By adopting the design of the beam type second buckle 124 with the elastic beam 1242, the problem of being unable to design a conventional buckle in limited space is avoided. The beam type second buckle 124 optimizes the use of space, avoids the influence of conventional buckle design on the internal components of the electronic device 100 and the layout space of the circuit board 150, and has smaller demand for Z direction space. Compared with the conventional female buckle, the weight is smaller, which is helpful for the thin design of the electronic device 100. The first buckle 112 and the second buckle 124 are fixed in limited space, avoiding the problem of the elastic contact 140 appearing to be too high, floating high and poor contact caused by the lack of buckles. The first buckle 112 and the second buckle 124 realize single direction limiting, avoiding the limitation that only conventional double-sided adhesive, dispensing and other forms can be used to realize the limiting effect in the case of space shortage, saving material cost and improving the detachable and reusable performance of the structure.

[0072] The design of the beam type second buckle 124 is not limited to the use scene of cooperating with the elastic contact 140, but can also be used in other single direction limiting scenes with spring pre-pressure, water pressure, air pressure and the like according to actual use, and can be used in mobile phones, computers or other electronic products, industrial equipment, daily necessities and the like.

[0073] The electronic device 100 can be a terminal, or can be another device other than the electronic device 100. For example, the electronic device 100 can be a mobile phone, a tablet, a notebook computer, a palmtop computer, a music playing device, a private network communication terminal device (e.g., a walkie-talkie), a mobile internet device (MID), an augmented reality / virtual reality / mixed reality device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), etc., and embodiments of the present application are not limited thereto.
