[0032] The embodiment of the present application provides a middle frame of a communication device. In a communication device including the middle frame of the communication device, the communication device can realize the antenna function through the middle frame of the communication device. For example, the communication device can be fed or grounded by contacting the metal elastic sheet on the circuit board with the middle frame.

[0033] Among them, the metal shrapnel can be a feeding shrapnel or a grounding shrapnel. The feeding shrapnel is mainly used to provide electrical signals to the middle frame antenna. The feeding shrapnel can be designed as an elastic conductive structure to establish a reliable electrical connection between the circuit board and the middle frame antenna. The feeding shrapnel not only requires good electrical conductivity but also needs to be able to withstand a certain amount of vibration and shock to ensure the stability of the feeding connection during the use of the communication device.

[0034] The grounding shrapnel is mainly used to guide the charges or noises on the middle frame antenna to the ground to avoid the communication device from being affected by electromagnetic interference and electrostatic discharge. The grounding shrapnel has good electrical conductivity and elasticity and can establish a stable grounding connection between the circuit board and the middle frame antenna to ensure the electrical safety and signal quality of the communication device.

[0035] In the middle frame of the communication device provided by the embodiment of the present application, the connecting part and the frame are respectively formed and embedded and matched. 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 connecting part has strong antioxidant ability, its electrical properties are more stable, and further the feeding shrapnel or the grounding shrapnel can be in stable contact with the middle frame through the connecting part, thus ensuring the stable communication function of the communication device.

[0036] In some embodiments, referring to Figures 1 to 3 , the present application provides a middle frame of a communication device, and the middle frame of the communication device includes:

[0037] A frame 1, the frame 1 forms an antenna radiator, and a connecting groove 11 is provided at a position on the inner side of the frame 1 as a feeding point of the antenna radiator, as Figure 3 shown;

[0038] A connecting part 2, the connecting part 2 includes a connecting body 21 and a protrusion 22, as Figure 2 shown; the protrusion 22 is embedded and matched with the connecting groove 11, the connecting body 21 protrudes from the connecting groove 11 and is used for electrical contact with the connecting shrapnel, and the surface of the connecting part 2 is made of an antioxidant conductive material.

[0039] In this embodiment, the frame 1 can form one or more antenna radiators 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 feeding point position, and further optimize the performance of the antenna radiator.

[0040] The connecting part 2 can be used as a feeding part or a grounding part of the antenna radiator to facilitate providing a feeding or grounding port for the antenna radiator; the connecting part 2 is embedded into the connecting groove 11 through the protrusion 22. For example, the connecting part 2 is formed into a structure similar to a nail and nailed into the frame 1, on the basis of facilitating the independent molding of the connecting part 2 and the frame 1, ensuring the connection effectiveness between the connecting part 2 and the frame 1.

[0041] Moreover, the surface of the connecting portion 2 is made of an oxidation-resistant conductive material. For example, the connecting portion 2 includes a central body and a surface layer body, the surface layer body wraps around the central body, and the material of the surface layer body is an oxidation-resistant conductive material; or the connecting portion 2 is entirely made of an oxidation-resistant conductive material, which can form a stable oxidation-resistant property on the surface of the connecting body 21 of the connecting portion 2, reducing the risk of forming an oxide film due to the long-term contact between the connecting spring piece and the connecting body 21, and ensuring the stability of the electrical contact between the connecting portion 2 and the connecting spring piece.

[0042] In one embodiment, the connecting body 21 and the protrusion 22 are integrally formed, and the materials of the connecting body 21 and the protrusion 22 are the same, so as to ensure the integrity of the structure of the connecting portion 2 on the basis of facilitating the formation of the connecting portion 2.

[0043] The connecting body 21 of the connecting portion 2 protrudes from the connecting groove 11 and is used for electrical contact with the connecting spring piece. The surface of the connecting portion 2 is made of an oxidation-resistant conductive material, which can facilitate the feeding or grounding of the antenna radiator through the connecting portion 2, so that while the antenna radiator realizes the wireless communication function, the stability of the wireless communication of the antenna radiator is improved.

[0044] In one embodiment, a main board is provided in a communication device including a communication device middle frame, and a connecting spring piece is provided on the main board. The connecting body 21 is in electrical contact with the connecting spring piece, increasing the electrical connection reliability between the main board and the above-mentioned antenna radiator and ensuring the stable communication function of the communication device.

[0045] In one embodiment, the conductivity of the connecting portion 2 is greater than that of the frame 1.

[0046] The conductivity of the frame 1 in the communication device middle frame is low, resulting in a large resistance of the frame 1; if the connecting spring piece is directly in electrical contact with the frame 1, it is easy to cause a large voltage drop on the frame 1, and the impurities in the frame 1 with low conductivity will reduce its chemical stability and surface reaction activity, generating an oxide film at the contact position between the frame 1 and the connecting spring piece, thereby increasing the contact resistance between the frame 1 and the connecting spring piece and causing the performance of the antenna radiator to decline.

[0047] In the embodiment of the present application, the connecting portion 2 with a conductivity greater than that of the frame 1 is embedded in the frame 1, and the connecting spring piece is in electrical contact with the connecting portion 2, which can reduce the voltage drop on the connecting portion 2, improve the signal transmission efficiency, enhance the chemical stability and surface reaction activity of the connecting portion 2, reduce the risk of generating an oxide film at the contact position between the connecting portion 2 and the connecting spring piece, and ensure the signal transceiver performance of the antenna radiator on the frame 1.

[0048] In one embodiment, the connecting body 21 and the protrusion 22 are made of the same material, and the connecting body 21 and the protrusion 22 are integrally formed, so as to ensure the integrity of the structure of the connecting part 2 on the basis of facilitating the formation of the connecting part 2.

[0049] In one embodiment, the conductivity range of the connecting part 2 is 48 - 80 MS / m, and the connecting part 2 is a copper part or a gold part.

[0050] In this embodiment, the whole connecting part 2 can be made of existing copper materials. For example, the connecting body 21 and the protrusion 22 are integrally formed with copper materials. The conductivity of the copper material is about 59.88 MS / m (megasiemens per meter), which can provide the connecting part 2 with high conductivity and anti-oxidation properties; or the whole connecting part 2 can be made of existing gold materials. For example, the connecting body 21 and the protrusion 22 are integrally formed with gold materials. The conductivity of the gold material is about 48.42 MS / m (megasiemens per meter), which can also provide the connecting part 2 with high conductivity and anti-oxidation properties, avoid the generation of oxide films at the contact positions with the connecting elastic pieces on the connecting part 2, and ensure the signal transmission ability of the antenna radiator on the frame 1.

[0051] In one embodiment, the conductivity of the frame 1 is less than or equal to 40 MS / m, and the frame 1 is an aluminum frame or an aluminum alloy frame.

[0052] In this embodiment, the whole frame 1 can be made of existing aluminum materials or aluminum alloy materials. 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.

[0053] In one embodiment, see Figure 1 and Figure 2 , the protrusion 22 is press-fitted into the connecting groove 11.

[0054] In this embodiment, the size of the protrusion 22 can be slightly larger than the size of the inner cavity of the connecting groove 11, so as to embed the protrusion 22 into the connecting groove 11 by extrusion, realize the press-fitting of the protrusion 22 into the connecting groove 11, ensure the connection strength between the connecting part 2 and the frame 1, and maintain the signal receiving and transmitting performance of the antenna radiator.

[0055] In a specific embodiment, the connecting groove 11 is a rectangular groove, the protrusion 22 is a rectangular protrusion, the width of the embedding cross-section of the protrusion 22 is greater than the corresponding width in the connecting groove 11, and / or the height of the embedding cross-section of the protrusion 22 is greater than the corresponding height in the connecting groove 11, so as to realize the press-fitting of the protrusion 22 into the connecting groove 11 when the protrusion 22 is pressed into the connecting groove 11.

[0056] In one embodiment, the protrusion 22 has a thread, and a threaded hole is formed in the connecting groove 11. The protrusion 22 is threadedly matched with the threaded hole, so that the protrusion 22 can be screwed into the connecting groove 11 by rotating the protrusion 22. On the basis of ensuring the connection strength between the connecting part 2 and the frame 1, the disassembly between the connecting part 2 and the connecting groove 11 can also be facilitated.

[0057] In a specific embodiment, the protrusion 22 is a cylindrical protrusion with external threads, and the connecting groove 11 is a threaded groove with internal threads formed inside. By screwing the protrusion 22 into the connecting groove 11, the threaded connection between the connecting part 2 and the connecting groove 11 can be achieved.

[0058] In one embodiment, see Figure 8 A side of the protrusion 22 close to the connecting body 21 forms an undercut edge 221 , and the protrusion 22 is disposed in the connecting groove 11 so that the undercut edge 221 is in an undercut fit with the connecting groove 11 .

[0059] In this embodiment, the protrusion 22 forms an undercut direction of the connecting part 2 toward the connecting body 21, and an opening is formed on the connecting groove 11. The protrusion 22 is embedded in the connecting groove 11 and allows the connecting body 21 to extend from the opening along the undercut direction; in a plane perpendicular to the undercut direction, the projection size of the protrusion 22 along the undercut direction can be larger than the projection size of the connecting body 21 along the undercut direction, and the size of the opening is between the projection size of the protrusion 22 and the projection size of the connecting body 21. The protrusion 22 is arranged in the connecting groove 11 and is stopped in the opening by the undercut edge 221. At the same time, the connecting body 21 can be easily extended from the connecting groove 11 from the opening. On the basis of ensuring that the connecting body 21 is in electrical contact with the connecting spring sheet, the connecting part 2 is prevented from being disengaged from the connecting groove 11, thereby ensuring the connection stability between the connecting part 2 and the frame 1.

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

[0061] In this embodiment, the inner side of the frame 1 may have one or more feeding points of the antenna radiator. When there is a feeding point of the antenna radiator on the inner side of the frame 1, the feeding point may be a feeding point or a grounding point of the antenna radiator, so as to feed or ground the antenna radiator through the electrical contact between the connecting body 21 and the connecting spring sheet; when there are multiple feeding points of the antenna radiator on the inner side of the frame 1, the multiple feeding points may all be feeding points, the multiple feeding points may all be grounding points, or some of the feeding points may be feeding points and the remaining feeding points may be grounding points. The specific method may be determined according to the number and structure of the antenna radiators formed on the frame 1 to ensure the stability of signal reception and transmission of the antenna radiator.

[0062] See also Figure 6 An embodiment of the present application further provides a communication device, which includes the above-mentioned communication device middle frame 100.

[0063] In this embodiment, the connection body 21 of the connection part 2 in the middle frame 100 of the communication device protrudes from the connection slot 11 and is used for electrical contact with the connection elastic sheet. The surface of the connection part 2 is made of an antioxidant conductive material, which is convenient for feeding or grounding the antenna radiator through the connection part 2, ensuring the stable communication function of the communication device.

[0064] In one embodiment, referring to Figures 5 to 7 , the communication device further includes a main board 200, and a connection elastic sheet 201 is arranged on the main board 200. The connection elastic sheet 201 is in electrical contact with the connection body 21.

[0065] In this embodiment, the connection elastic sheet 201 can be a feeding elastic sheet or a grounding elastic sheet. When the connection elastic sheet 201 is a feeding elastic sheet, the connection part 2 can be used as a feeding part and is in electrical contact with the connection elastic sheet through the connection body 21, so as to realize the feeding from the main board 200 to the antenna radiator on the frame 1, ensuring the reliability and coverage of the signal transmission of the antenna radiator.

[0066] When the connection elastic sheet 201 is a grounding elastic sheet, the connection part 2 can be used as a grounding part and is in electrical contact with the connection elastic sheet through the connection body 21, so as to realize the grounding from the antenna radiator on the frame 1 to the main board 200, improving the signal transmission quality of the antenna radiator and avoiding interference with the signal of the antenna radiator.
