Description

Technical Field

[0001] This application relates to the field of electronic devices, and more specifically, to card socket connectors and terminal devices. Background Technology

[0002] The subscriber identity module (SIM) card is a storage unit used to store information such as the identity identifier, key, and contact list of mobile communication users. When inserted into the corresponding card slot connector of the mobile phone, it enables the mobile phone to make calls and provide data services.

[0003] Currently, split-type card socket connectors are widely used in the market. These connectors include a card socket housing and a push rod. The push rod slides with the card socket housing so that it can move along its length, ultimately ejecting or resetting the card tray housed in the card socket housing.

[0004] In one design of a mobile phone equipped with a separate card slot connector, the separate card slot connector is located in the area where the antenna is arranged. This design may cause the mobile phone to generate large radiated spurious emissions (RSE), which may lead to the risk of the mobile phone being removed from the market, requiring rectification, recall, discontinuation of sales, and fines.

[0005] Therefore, there is a need to provide a card slot connector that can reduce the problem of mobile phones failing to meet RSE standards. Summary of the Invention

[0006] This application provides a card slot connector and a terminal device that can reduce the problem of mobile phones failing to meet RSE standards.

[0007] In a first aspect, a card holder connector is provided, the card holder connector comprising:

[0008] Card holder housing, push rod, and lever, wherein the card holder housing is used to accommodate the card tray, wherein...

[0009] The first side of the card holder housing is provided with a sliding structure to accommodate the push rod. The push rod can slide along the sliding structure. The push rod or the sliding structure is insulated. The second side of the card holder housing is provided with a lever. The lever and the push rod are mechanically connected. During the sliding of the push rod along the sliding structure, the lever can push out the card holder. The first side and the second side are adjacent.

[0010] Therefore, the card slot connector provided in this application embodiment, with its push rod or sliding structure insulated, achieves non-conductivity between the push rod and the sliding structure, i.e., non-conductivity between the push rod and the card slot housing. This avoids the unstable conductivity caused by discontinuous contact between the push rod and the sliding structure without altering the phone's architecture—specifically, by placing the card slot connector near the antenna. This naturally reduces RSE (Resistant Surface Equilibrium). The structure is simple and easy to implement, which is of great significance for manufacturers addressing RSE non-compliance issues in RSE regulations. Furthermore, since the push rod's function is to eject the card tray, the insulated contact between the push rod and the sliding structure does not affect the functionality of the card slot connector.

[0011] Optionally, the surface of the push rod that contacts the sliding structure is coated with an insulating layer.

[0012] Optionally, the surface of the push rod is coated with an insulating layer.

[0013] Optionally, the push rod is made of an insulating material.

[0014] For example, the insulating material may be ceramic, graphene, or carbon fiber.

[0015] Optionally, the surface of the sliding structure in contact with the push rod is coated with an insulating layer.

[0016] Optionally, the insulating layer is made of resin.

[0017] Optionally, the sliding structure has at least one spring piece extending toward the push rod on its surface near the push rod, and the spring piece and the push rod are pressed into contact during the sliding process of the push rod.

[0018] Therefore, by setting a spring on the surface of the sliding structure near the push rod, the gap between the push rod and the sliding structure can be reduced by the spring. This increases the stability of the contact between the push rod and the sliding structure during the sliding process, while still allowing the push rod to slide in the sliding structure.

[0019] Optionally, the first surface of the sliding structure is provided with at least one spring tab, and the first surface is close to the area of ​​the card holder housing used to accommodate the card tray.

[0020] In general, the gap between the surface of the card holder housing near the area used to accommodate the card tray (e.g., the first surface) and the push rod in a sliding structure may be large. By setting a spring on the first surface, the design is simple and easy to implement.

[0021] Optionally, the sliding structure has at least one protrusion on its surface opposite to the first surface, and the protrusion and the push rod are pressed together during the sliding of the push rod along the sliding structure.

[0022] Therefore, by setting a convex hull on the surface opposite to the surface where the spring is set, the gap between the push rod and the sliding structure can be further reduced by the convex hull, and point contact between the push rod and the sliding structure can be achieved to better achieve stable contact between the push rod and the sliding structure.

[0023] Secondly, a card holder connector is provided, the card holder connector comprising:

[0024] The card holder housing, push rod, and lever, wherein the card holder housing is used to accommodate the card tray, wherein...

[0025] The first side of the card holder housing is provided with a sliding structure to accommodate the push rod. The surface of the sliding structure near the push rod is provided with at least one spring piece extending toward the push rod. During the sliding of the push rod along the sliding structure, the spring piece and the push rod are pressed into contact. The second side of the card holder housing is provided with a lever. The lever and the push rod are mechanically connected. During the sliding of the push rod along the sliding structure, the lever can push out the card holder. The first side and the second side are adjacent. The card holder housing and the push rod are both made of metal.

[0026] Therefore, the card slot connector provided in this application embodiment has a spring piece provided on the inner surface of the sliding structure in the card slot housing for accommodating the push rod. The spring piece reduces the gap between the push rod and the sliding structure, so that the spring piece and the push rod can be pressed into contact during the process of the push rod sliding along the sliding structure, so as to make the push rod and the sliding structure in stable contact as much as possible. In this way, even if there is a connection between the push rod and the sliding structure, the RSE generated by the device can be reduced. In addition, since the spring piece has good deformation characteristics, even if the push rod and the sliding structure are in contact, the push rod can still slide in the sliding structure.

[0027] Optionally, the first surface of the sliding structure is provided with at least one spring tab, and the first surface is close to the area of ​​the card holder housing used to accommodate the card tray.

[0028] In general, the gap between the surface (e.g., the first surface) of the sliding structure near the area of ​​the card holder housing used to accommodate the card tray and the push rod may be large. By setting a spring on the first surface, the design is simple and easy to implement.

[0029] Optionally, the sliding structure has at least one protrusion on its surface opposite to the first surface, and the protrusion and the push rod are pressed together during the sliding of the push rod along the sliding structure.

[0030] Therefore, by setting a convex hull on the surface opposite to the surface where the spring is set, the gap between the push rod and the sliding structure can be further reduced by the convex hull, and point contact between the push rod and the sliding structure can be achieved to better achieve stable contact between the push rod and the sliding structure.

[0031] Thirdly, a terminal device is provided, the terminal device including an antenna and a card slot connector of any possible implementation of the first aspect, wherein the closest distance between the feed point of the antenna and the card slot connector is less than or equal to 10 mm.

[0032] Optionally, the closest distance between the antenna feed point and the card slot connector is less than or equal to 5 mm.

[0033] In the fourth direction, a terminal device is provided, the terminal device including an antenna and a socket connector of any possible implementation of the second aspect, wherein the closest distance between the feed point of the antenna and the socket connector is less than or equal to 10 mm.

[0034] Optionally, the closest distance between the antenna feed point and the card slot connector is less than or equal to 5 mm. Attached Figure Description

[0051] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0052] Radiated spurious emission (RSE) is a crucial performance indicator for radio transmitting equipment. It refers to emissions outside the operating frequency generated or amplified by the radio transmitting equipment when connected to a non-radiating purely resistive load or in receiver mode, radiating through the equipment casing, power supply, control equipment, and audio cables. RSE testing measures these emissions outside the operating frequency, including harmonics, harmonic components, and parasitic components. Excessive RSE at a particular frequency can render equipment operating at that frequency unusable, negatively impacting related business operations. RSE testing is mandatory for all radio transmitting equipment in both domestic and international certifications. Furthermore, according to RSE regulations, exceeding preset RSE values ​​can lead to risks such as equipment removal from shelves, rectification, recall, sales suspension, and fines.

[0053] Once radio transmitting equipment fails to meet RSE (Responsiveness and Segregation) standards, from a practical perspective, researching ways to reduce RSE issues is not easy, especially for high-power transmitting products such as mobile phones. On one hand, RSE non-compliance is a low-probability event, primarily because radio transmitting equipment is required to undergo RSE testing before sale; only equipment meeting RSE standards is allowed to be sold. On the other hand, many factors can cause RSE non-compliance, and identifying the correct cause requires significant creative effort from those skilled in the art.

[0054] The SIM card slot connector is a crucial component of a mobile phone, used to house the SIM card for call and data services. Due to the need for miniaturization in mobile phones, separate SIM card slot connectors have become widely used. In mobile phones equipped with separate SIM card slot connectors, a low-probability and difficult-to-reproduce response quality (RSE) non-compliance issue has been discovered. For these difficult-to-reproduce RSE non-compliance situations—for example, the same phone, under the same test conditions, might exhibit RSE non-compliance in one period but not in another—this presents a significant challenge for those skilled in the art in researching how to improve RSE.

[0055] Based on this, we continued to conduct troubleshooting experiments on various components of the phone. We found that when the split card slot connector is placed near the antenna, the unstable contact between the push rod and the sliding structure will generate large harmonics, resulting in a large RSE. When the split card slot connector is placed far away from the antenna, the generated RSE is smaller or may not even occur.

[0056] Therefore, we believe that the large RSE (Reduction of SE) is caused by the design of the card slot connector being close to the antenna. However, due to certain objective conditions, the card slot connector needs to be placed in the vicinity of the antenna. Based on this, embodiments of this application provide a card slot connector that, through relevant improvements, can effectively reduce the RSE of the mobile phone.

[0057] Below, in conjunction with Figures 1 to 10 The embodiments of this application will be described in detail below.

[0058] First, the directions of the coordinate systems in the various figures of the embodiments of this application will be explained. The x, y, and z directions are perpendicular to each other. The y direction can be understood as the length direction of the push rod, and the z direction can be understood as the thickness direction of the card slot connector.

Figure 6 Figure (b) shows a schematic structural diagram of a local region of the sliding structure. Figure 6 (c) is a cross-sectional view of a partial region B of the sliding structure in the xy plane according to an embodiment of this application.

[0060] It should be understood that Figures 1 to 6 The structure of each component and the connection relationship between the components shown are for illustrative purposes only and should not be construed as limiting the embodiments of this application.

[0061] refer to Figures 1 to 6 The card slot connector 100 includes: a card slot housing 110, a push rod 120, and a lever 130.

[0062] The card holder housing 110 is used to accommodate the card tray 101 and is used to attach to the circuit board. The first side of the card holder housing 110 is provided with a sliding structure 111 for accommodating the push rod 120. The push rod 120 can slide along the sliding structure 111. The push rod 120 and the sliding structure 111 are insulated from each other. The second side of the card holder housing 110 is provided with a lever 130. The lever 130 and the push rod 120 are mechanically connected. The lever 130 can contact the card tray 101. During the sliding of the push rod 120 along the sliding structure 111, the lever 130 can push out the card tray 101. The first side and the second side are adjacent to each other.

[0063] It should be noted that there are multiple ways to mechanically connect the lever 130 and the push rod 120. For example, a groove can be provided on the push rod 120, and the end of the lever 130 can be inserted into the groove to achieve mechanical connection between the lever 130 and the push rod 120.

[0064] Continue to refer to Figure 1 The process of card removal and card insertion using the card slot connector 100 will be explained.

[0065] During the card retrieval process, the user pushes the push rod 120, which moves along the sliding structure 111. Figure 1 The sliding motion in the first direction, as shown, causes the lever 130 to rotate in the opposite direction (i.e., the second direction) via the sliding of the push rod 120, thus pushing the card holder 1010 out in the opposite direction (i.e., the second direction). During the card insertion process, the user moves along... Figure 1 The second direction pushes the card holder 101, which drives the lever 130 to rotate in the opposite direction (i.e., the first direction). The lever 130 drives the push rod 120 to slide in the sliding structure 111 in the opposite direction (i.e., the first direction) to achieve the mounting.

[0066] In this embodiment, the push rod or sliding structure is insulated to achieve non-conductivity between the push rod and the sliding structure, that is, non-conductivity between the push rod and the card holder housing. In this way, for mobile phones with the card holder connector located in the area close to the antenna, RSE can be effectively reduced.

[0067] The implementation principle of the embodiments of this application will be explained in detail below.

[0068] In this application embodiment, through extensive experiments on existing split-type card slot connectors, we found that for card slot connectors located near the antenna, the problem of non-compliance with RSE (Resonance Sequence) is difficult to reproduce due to discontinuous contact between the push rod and the sliding structure. Discontinuous contact refers to the difficulty in maintaining a constant number of contact points and contact force during the contact process. This discontinuity leads to an unstable conductive state between the components. It is precisely because of this discontinuous contact that the RSE obtained at different times varies, resulting in this difficult-to-reproduce RSE non-compliance problem.

[0069] Further analysis reveals that in existing split-type card slot connectors, the card slot housing is made of metal. To ensure the strength of the push rod pushing out of the card tray, the push rod is also made of metal. To ensure the push rod can slide normally, there is a certain gap between the card slot housing and the push rod. This gap design allows the push rod to slide smoothly in the sliding structure of the card slot housing. However, during the sliding process, there is unstable contact between the push rod and the card slot connector, that is, there is discontinuous conduction on the contact surface between the push rod and the card slot connector. Since the antenna is located near the card slot connector, this discontinuous conduction will generate radio frequency current, thereby causing the mobile phone's RSE (Radio Efficiency and Security) to fail to meet the standards.

[0070] Based on the above analysis, in this embodiment, the push rod or sliding structure is insulated to achieve non-conductivity between the push rod and the sliding structure, that is, non-conductivity between the push rod and the card slot housing. Thus, without changing the phone's architecture—specifically, with the card slot connector positioned near the antenna—the problem of unstable conductivity caused by discontinuous contact between the push rod and the sliding structure is avoided, naturally reducing RSE (Resistant Surface Effort). The structure is simple and easy to implement, which is of great significance for manufacturers in addressing RSE non-compliance issues in RSE regulations. Furthermore, since the push rod's function is to eject the card tray, the insulated push rod or sliding structure does not affect the function of the card slot connector.

[0071] In this application embodiment, by way of example, the push rod or sliding structure can be insulated in the following three ways (i.e., way 1, way 2 and way 3).

[0072] Method 1

[0073] In one possible implementation, the surface of the push rod 120 that contacts the sliding structure 111 is a surface coated with an insulating layer.

[0074] The surface of the push rod 120 that contacts the sliding structure 111 can be the entire surface of the push rod 120 or a portion thereof, depending on the sliding range between the push rod 120 and the sliding structure 111. For example, if the push rod 120 contacts the entire sliding structure 111 during its sliding process, the surface of the push rod 120 in contact with the sliding structure 111 can be the entire surface, and an insulating layer 121 can be coated on the entire surface of the internal structure 122 of the push rod 120; if the push rod 120 contacts the sliding structure 111 partially during its movement, the surface of the push rod 120 in contact with the sliding structure 111 is a portion of the surface of the push rod 120, and an insulating layer 121 can be coated on a portion of the internal structure 122 of the push rod 120.

[0075] For example, refer to Figure 4 In (b), the entire surface of the internal structure 122 of the push rod 120 is coated with an insulating layer 121, and the surface in contact with the sliding structure 211 is 121-1.

[0076] For example, refer to Figure 5 In (a) and (c), the surface 122-1 of the internal structure 122 of the push rod 120 is coated with an insulating layer 123, and the surface that contacts the sliding structure 111 is surface 123-1.

[0077] For example, refer to Figure 5In (b) and (c), the surface 122-2 of the internal structure 122 of the push rod 120 is coated with an insulating layer 124, and the surface that contacts the sliding structure 111 is surface 124-1.

[0078] In practice, an insulating layer can be sprayed onto the internal structure 122 of the push rod 120 using various methods. For example, the insulating layer can be sprayed onto the internal structure 122 of the push rod 120 using electrophoresis.

[0079] The insulating layer can be made of any material that can achieve the insulating function, such as ceramics, Teflon, physical vapor deposition (PVD) coatings, without any limitation.

[0080] Generally, we want the insulating layer to adhere well to the surface of the component. Based on this, resin can be used as the material for the insulating layer, for example.

[0081] Method 2

[0082] In another possible implementation, the push rod 120 can be made of an insulating material.

[0083] Here, the insulating material of the push rod 120 can be any material that can achieve the insulating function, and there are no restrictions. However, in order to make the push rod 120 have a certain strength, some materials with good strength properties can be used, such as ceramics, graphene, and carbon fiber materials.

[0084] Method 3

[0085] In another possible implementation, the surface of the sliding structure 111 that contacts the push rod 120 is a surface coated with an insulating layer.

[0086] refer to Figure 3 For example, the surface of the sliding structure 111 that contacts the push rod 120 can be surfaces 111-21 of the sliding structure 111 near the area of ​​the card holder housing 110 used to receive the card tray, see reference. Figure 3 In (c), the outer surface of the insulating layer 111-2 is surface 111-21, and the insulating layer 111-2 is coated on a portion 111-1 of the sliding structure 111. (See reference) Figure 6 The surface of the sliding structure 111 that contacts the push rod 120 can be the surfaces 113-31 of the opposing surfaces 111-21 in the sliding structure 111, for reference. Figure 6 In (c), the outer surface of the insulating layer 111-3 is surface 111-31, and the insulating layer 111-3 is coated on a portion of the sliding structure 111, region 111-4.

[0087] It should be understood that the above Figure 3 and Figure 6 The area shown as having an insulating layer on the sliding structure is for illustrative purposes only. Any area of ​​the sliding structure that comes into contact with the push rod can be coated with an insulating layer, and no limitation is made here.

[0088] In specific implementations, an insulating layer can be sprayed onto the area of ​​the sliding structure 111 that contacts the push rod 120 (e.g., areas 111-1 and / or 111-4) in various ways. For example, the insulating layer can be sprayed onto the area of ​​the sliding structure 111 that contacts the push rod 120 by electrophoresis.

[0089] Alternatively, resin can be used as the material for the insulating layer.

[0090] It should be noted that methods 1, 2 and 3 can be used individually, or any one of methods 1 or 2 can be used in combination with method 3, that is, the push rod and the sliding structure are insulated at the same time. This application embodiment does not make any limitation.

[0091] Based on the reasons for the RSE (Resistance-Oriented Sequence) failure of the aforementioned split-type card socket connector, one solution is to prevent the push rod and the sliding structure in the card socket housing from conducting. For example, by achieving insulated contact between the push rod and the sliding structure in the card socket housing, RSE is reduced. Alternatively, another solution is to achieve stable contact between the push rod and the sliding structure to achieve stable conduction, which also reduces RSE.

[0092] The following, combined with Figures 7 to 10 From the perspective of achieving stable contact between the push rod and the card holder connector, another card holder connector according to an embodiment of this application will be described. In this embodiment, the main idea of ​​achieving stable contact between the push rod and the card holder connector is to minimize the gap between the push rod and the sliding structure in the card holder connector that accommodates the push rod while still being able to eject the card tray.

[0093] Figure 7 The diagram shown is a schematic structural diagram of the card slot connector according to an embodiment of this application. Figure 8 The image shown is a rear view of the card slot connector and card tray assembly according to an embodiment of this application. Figure 9 The figure shown is a cross-sectional view of a partial region A of the card slot connector according to an embodiment of this application in the xy plane. Figure 10 The diagram shown is a schematic structural diagram of the card holder shell according to an embodiment of this application.

[0094] refer to Figures 7 to 10 The card slot connector 200 includes: a card slot housing 210, a push rod 220, and a lever 230.

[0095] The card holder housing 210 is used to accommodate the card tray 101 and is used to attach to the circuit board.

[0096] The first side of the card holder housing 210 is provided with a sliding structure 211 for accommodating the push rod 220. At least one spring piece 211-0 extending toward the push rod 220 is provided on the surface of the sliding structure 211 near the push rod 220. During the process of the push rod 220 sliding along the sliding structure 211, the spring piece 211-0 and the push rod 220 are pressed into contact.

[0097] A lever 230 is provided on the second side of the card holder housing 210. The lever 230 is connected to the push rod 220. The lever 230 contacts the card tray 101. During the sliding process of the push rod 220 along the sliding structure 211, the lever 230 can push out the card tray 101. The first side and the second side are adjacent. The materials of the card holder housing 210 and the push rod 220 are both metal.

[0098] Among them, the spring piece 211-0 is an elastic component with good deformation ability. It can deform under the action of external force, and when the external force is removed, the material can return to its properties before deformation.

[0099] The spring piece 211-0 contacts the push rod 220. In this way, as the push rod 220 slides along the sliding structure 211, the spring piece 211-0 can make a tight contact with the push rod 220. On the one hand, this tight contact can make the push rod 220 and the sliding structure 211 make stable contact as much as possible. On the other hand, the good deformation ability of the spring piece 211-0 can make the sliding of the push rod 220 in the sliding structure 211 relatively easy.

[0100] The surface of the sliding structure 211 near the push rod 220 can be understood as the inner surface of the sliding structure 211, and the space formed by the inner surface of the sliding structure 211 is used to accommodate the push rod 220.

[0101] The number of spring pieces 211-0 can be one or more, without any limitation. When there are multiple spring pieces 211-0, there is a certain gap between two adjacent spring pieces 211-0. The spring pieces 211-0 and the sliding structure 211 can be formed by an integral molding process, or they can be fixedly connected to the sliding structure 211 as independent components, without any limitation.

[0102] The spring piece 211-0 can be disposed in any area of ​​the inner surface of the sliding structure 211 that can contact the push rod 220, and this application embodiment does not impose any limitation. In one possible structural design, the gap between the surface of the sliding structure 211 near the area of ​​the card holder housing 210 used to accommodate the card tray 101 and the push rod 220 may be relatively large. Based on this, optionally, referring to... Figure 10The spring piece 211-0 can be set on the first surface 211-1 of the sliding structure 211. The first surface 211-1 can be understood as a surface in the sliding structure near the area of ​​the card holder housing 210 used to accommodate the card tray 101.

[0103] Therefore, the card slot connector provided in this application embodiment has a spring piece provided on the inner surface of the sliding structure in the card slot housing for accommodating the push rod. The spring piece reduces the gap between the push rod and the sliding structure, so that the spring piece and the push rod can be pressed into contact during the process of the push rod sliding along the sliding structure, so as to make the push rod and the sliding structure in stable contact as much as possible. In this way, even if there is a connection between the push rod and the sliding structure, the RSE generated by the device can be reduced. In addition, since the spring piece has good deformation characteristics, even if the push rod and the sliding structure are in contact, the push rod can still slide in the sliding structure.

[0104] To achieve better stable contact between the push rod and the sliding mechanism, optionally, refer to... Figure 9 The sliding structure 211 has at least one protrusion 211-3 on its surface relative to the first surface 211-1. During the sliding of the push rod 220 along the sliding structure 211, the protrusion 211-3 and the push rod 220 are pressed into contact.

[0105] The number of convex hulls 211-3 can be one or more, and no limitation is made here. When there are multiple convex hulls 211-3, there is a certain gap between two adjacent convex hulls 211-3.

[0106] The convex hull 211-3 can achieve point contact between the sliding structure 211 and the push rod 220. Compared with the surface contact method, it can achieve more stable contact between the push rod 220 and the sliding structure 211.
