[0031] The embodiments of the present application provide a middle frame of a communication device. In a communication device including the middle frame of the communication device, the communication device can implement an antenna function through the middle frame of the communication device. For example, by contacting the middle frame with a metal elastic sheet, the power feeding or grounding of the middle frame of the communication device can be realized.

[0032] In the communication device provided by the embodiment of the present application, the connecting part and the frame are formed separately, and the connecting part is sleeved and matched with the bump. At the same time, the surface of the connecting part is made of an antioxidant conductive material, so that during the long-term use of the communication device, the feeding elastic sheet or the grounding elastic sheet can stably contact the middle frame through the connecting part, thereby ensuring the stable communication function of the communication device.

[0033] In some embodiments, referring to Figure 1 , the present application provides a middle frame of a communication device, and the middle frame of the communication device includes:

[0034] A frame 1, the frame 1 forms an antenna radiator, and a bump 11 is integrally connected to the inner side of the frame 1. The bump 11 is located at the position of the feeding point of the antenna radiator.

[0035] A connecting part 2, the connecting part 2 is sleeved on the bump 11 and is used for electrical contact with the connecting elastic sheet, and the surface of the connecting part is made of an antioxidant conductive material.

[0036] In this embodiment, the frame 1 can form one or more antenna radiators, so as to effectively utilize the space of the frame 1 to set the antenna radiator and reduce the occupation of the internal space of the communication device by the antenna radiator; moreover, the effective length of the antenna can be controlled by adjusting the position of the feeding point, thereby optimizing the performance of the antenna radiator.

[0037] The bump 11 can be integrally connected to the frame 1 to ensure the structural integrity of the middle frame of the communication device; and the bump 11 is located at the position of the feeding point of the antenna radiator, so as to facilitate providing a feeding or grounding path for the antenna radiator through the cooperation of the connecting part 2 and the bump 11.

[0038] The connecting part 2 can be used as the feeding part or the grounding part of the antenna radiator, so as to provide a feeding or grounding port for the antenna radiator; the connecting part 2 is sleeved on the bump 11 and completely wraps the bump 11, that is, the connecting part 2 is formed into a structure similar to a tongue sleeve and sleeved on the bump 11. On the basis of facilitating the independent molding of the connecting part 2 and the frame 1, the connection effectiveness between the connecting part 2 and the frame 1 is ensured.

[0039] Moreover, the surface of the connecting part 2 is made of an antioxidant conductive material. For example, the connecting part 2 includes an inner layer structure and an outer layer structure. The inner layer structure is sleeved on the bump 11, and the outer layer structure is wrapped on the side of the inner layer structure away from the bump 11, and the material of the outer layer structure is an antioxidant conductive material; or the connecting part 2 is entirely made of an antioxidant conductive material, which can form a stable antioxidant layer on the surface of the connecting part 2, reducing the risk of forming an oxide film due to the long-term contact between the connecting elastic sheet and the connecting part 2, and ensuring the stability of the electrical contact between the connecting part 2 and the connecting elastic sheet. Or the inner surface of the connecting part 2 in contact with the bump is made of a material with high electrical conductivity, and the outer surface is made of an antioxidant conductive material.

[0040] In one embodiment, a main board is disposed in a communication device including a middle frame of the communication device. A connecting elastic piece is disposed on the main board. The connecting portion 2 is in electrical contact with the connecting elastic piece, realizing signal transmission between the main board and the antenna radiator. Moreover, the surface of the connecting portion is made of an oxidation-resistant conductive material, increasing the electrical connection reliability between the main board and the antenna radiator and ensuring the stable communication function of the communication device.

[0041] In one embodiment, the conductivity of the connecting portion 2 is greater than the conductivity of the bump 11.

[0042] The conductivity of the middle frame 1 and the bump 11 in the communication device middle frame is relatively low, resulting in a relatively large resistance of the frame 1. If the connecting elastic piece is directly in electrical contact with the bump 11 of the frame 1, it is likely to cause a relatively large voltage drop on the frame 1. Moreover, impurities in the frame 1 with low conductivity will reduce its chemical stability and surface reactivity, generating an oxide film at the contact position between the bump 11 and the connecting elastic piece, thereby increasing the contact resistance between the bump 11 and the connecting elastic piece and causing a decline in the performance of the antenna radiator.

[0043] In the embodiment of the present application, the connecting portion 2 with a conductivity greater than that of the bump 11 is sleeved on the bump 11, and the connecting elastic piece is in electrical contact with the connecting portion 2, reducing the voltage drop on the connecting portion 2. That is, a bridge for connection is formed between the connecting elastic piece and the bump 11 through the connecting portion 2, which can improve the chemical stability and surface reactivity of the connecting portion 2 on the basis of improving the signal transmission efficiency, reduce the risk of generating an oxide film at the contact position between the connecting portion 2 and the connecting elastic piece, and ensure the signal transceiver performance of the antenna radiator on the frame 1.

[0044] In one embodiment, the conductivity range of the connecting portion 2 is 48 - 80 MS / m (mega Siemens per meter), and the conductivity of the bump 11 is less than or equal to 40 MS / m.

[0045] In this embodiment, the conductivity of the connecting portion 2 can be set to be greater than or equal to 48 MS / m. For example, the conductivity of the connecting portion 2 is set to 50 MS / m, 60 MS / m, or 70 MS / m to reduce the resistance of the electrical contact between the connecting elastic piece and the connecting portion 2, alleviate the problem of forming an oxide film on the surface of the connecting portion 2, and ensure the signal transmission stability of the antenna radiator on the frame 1.

[0046] In one embodiment, the connecting portion 2 is a copper portion or a gold portion.

[0047] In this embodiment, the connecting part 2 can be made of existing copper material as a whole. The conductivity of the copper material is about 59.88 MS / m (mega Siemens per meter), which can provide the connecting part 2 with the characteristics of high conductivity and oxidation resistance; alternatively, the connecting part 2 can be made of existing gold material as a whole. The conductivity of the gold material is about 48.42 MS / m (mega Siemens per meter), which can also provide the connecting part 2 with the characteristics of high conductivity and oxidation resistance, avoiding the generation of oxide film at the contact position between the connecting part 2 and the connecting elastic piece, and ensuring the signal transmission ability of the antenna radiator on the frame 1.

[0048] In one embodiment, the bump 11 is an aluminum bump or an aluminum alloy bump.

[0049] In this embodiment, when the bump 11 is an aluminum bump, both the frame 1 and the bump 11 can be made of aluminum structure and integrally formed; when the bump 11 is an aluminum alloy bump, both the frame 1 and the bump 11 can be made of aluminum alloy structure and integrally formed.

[0050] The conductivity of the aluminum alloy material is between 10 and 40 MS / m. The conductivity of the aluminum alloy material is significantly less than that of the copper material and the gold material, which can reduce electromagnetic interference and ensure the stability of each device in the middle frame of the communication device.

[0051] In one embodiment, a rough surface is formed on the inner wall of the connecting part 2. The connecting part 2 is sleeved on the outer surface of the bump 11, and the bump 11 is fitted with the rough surface.

[0052] In this embodiment, the rough surface of the inner wall of the connecting part 2 can be obtained by means of laser engraving, silk screening or electroplating treatment. The connecting part 2 is sleeved on the outer surface of the bump 11 and the bump 11 is fitted with the rough surface, which can increase the electrical connection reliability between the inner wall of the connecting part 2 and the bump 11, and can also prevent the connecting part 2 from disengaging from the bump 11.

[0053] In one embodiment, see Figures 1 to 3 , the connecting part 2 and the bump 11 are interference-fitted.

[0054] In this embodiment, the size of the bump 11 can be slightly larger than the size of the inner cavity of the connecting part 2, so that the bump 11 is embedded into the connecting part 2 by extrusion, realizing the interference plug-in connection between the bump 11 and the connecting part 2, ensuring the connection strength between the connecting part 2 and the frame 1, and maintaining the signal receiving and transmitting performance of the antenna radiator.

[0055] In a specific embodiment, a rectangular groove is formed inside the connecting portion 2, the convex block 11 is a rectangular convex block, the connecting portion 2 is sleeved on the convex block 11 along the sleeving direction, and in the direction perpendicular to the sleeving direction, the size of the convex block 11 is larger than the corresponding size inside the rectangular groove. For example, the width dimension of the convex block 11 in the width direction is larger than the corresponding width dimension inside the rectangular groove, and the width dimension is perpendicular to the sleeving direction, and / or the height dimension of the convex block 11 in the height direction is larger than the corresponding height dimension inside the rectangular groove, and the height dimension is perpendicular to both the sleeving direction and the width direction, so as to realize the interference plug connection between the convex block 11 and the connecting portion 2 when the convex block 11 is pressed into the connecting portion 2.

[0056] In one embodiment, the convex block 11 has threads, a threaded hole is formed inside the connecting portion 2, and the connecting portion 2 is in threaded cooperation with the convex block 11 through the threaded hole, so as to screw the connecting portion 2 onto the convex block 11 by rotating the connecting portion 2. On the basis of ensuring the connection strength between the connecting portion 2 and the frame 1, it is also convenient for the disassembly between the connecting portion 2 and the frame 1.

[0057] In one embodiment, the connecting portion 2 has an opening, a large end is formed at one end of the convex block 11 away from the frame 1, and a small end is formed at one end of the convex block 11 close to the frame 1. In the plane perpendicular to the extending direction from the large end to the small end, the projection dimension of the large end along the above-mentioned extending direction is larger than the projection dimension of the small end along the above-mentioned extending direction;

[0058] The size of the opening is between the projection dimension of the large end and the projection dimension of the small end, so that the convex block 11 and the connecting portion 2 are in reverse buckling fit.

[0059] In this embodiment, in at least one direction perpendicular to the extending direction from the large end to the small end, the size of the opening is between the projection dimension of the large end and the projection dimension of the small end, and the reverse buckling fit between the convex block 11 and the connecting portion 2 can be realized; the large end of the convex block 11 is arranged in the connecting portion 2 and is stopped in the opening by the reverse buckling edge on the side of the large end close to the small end, and at the same time, the small end can be conveniently extended out of the connecting portion 2 through the opening and then connected to the frame 1. On the basis of ensuring the electrical contact between the connecting portion 2 and the connecting elastic piece, the disconnection between the connecting portion 2 and the convex block 11 is prevented, and the connection stability between the connecting portion 2 and the frame 1 is ensured.

[0060] In one embodiment, the feeding point includes at least one of a feeding point and a grounding point.

[0061] In this embodiment, one or more bumps 11 may be provided inside the frame 1 to form one or more feeding points of the antenna radiator inside the frame 1. When there is one feeding point of the antenna radiator inside the frame 1, this feeding point may be the feeding point or the grounding point of the antenna radiator, so as to facilitate the feeding or grounding of the antenna radiator through the electrical contact between the connecting portion 2 and the connecting elastic sheet; when there are multiple feeding points of the antenna radiator inside the frame 1, multiple feeding points may all be feeding points, multiple feeding points may also all be grounding points, or some feeding points may be feeding points and the remaining feeding points may be grounding points. Specifically, it can be determined according to the number and structure of the antenna radiators formed on the frame 1 to ensure the signal transceiver stability of the antenna radiator.

[0063] In this embodiment, the connecting portion 2 in the middle frame 100 of the communication device is sleeved on the bump 11 and is used for electrical contact with the connecting elastic sheet.
