Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings.

Radiated stray interference (RSE) is an important indicator for detecting the performance of radio transmission equipment, and means that when the radio transmission equipment is connected to a non-radiative pure impedance load or in a receiver state, the radio transmission equipment generates or amplifies emissions outside the operating frequency radiated by the equipment enclosure, a power supply, control equipment and various cables of audio frequency, and when the RES is tested, the emissions outside the operating frequency, including harmonics, harmonic components, parasitic components and the like, are tested. If the RSE of a radio transmitting device at a certain frequency is too large, the device operating at the frequency cannot be used normally, and the development of related services is adversely affected. Any radio transmitting apparatus is required to perform RSE detection in national or international certification, and may be exposed to risks of down shelves, rectification, recalls, down sales, fines, etc., if the RSE exceeds a preset value, as stipulated by the RSE regulations.

Once the radio transmitting equipment has the problem that the RSE is not up to standard, it is not easy to study how to reduce the RSE from the practical operation point of view, especially for high power transmitting products such as mobile phones. On the one hand, the failure to reach the RSE is a low probability event, mainly because, for radio transmitting devices, the devices are required to be detected before selling, and the devices are allowed to be sold after the RSE reaches the standard. On the other hand, the reasons for causing the RSE not to reach the standard are many, and how to investigate other reasons to obtain the correct reasons for causing the RSE not to reach the standard is possible to obtain the RSE not to reach the standard by spending a great deal of labor and creativity for the technicians in the field.

The card holder connector is an important component of the mobile phone and is used for accommodating the SIM card so as to realize the conversation and data service of the mobile phone. At present, due to the requirement of space miniaturization of the mobile phone, the split type card seat connector is widely applied. In a mobile phone configured with a split-type card holder connector, the problem that the RSE which is less likely to recur does not reach the standard is found, and for the condition that the RSE which is less likely to recur does not reach the standard, for example, under the same test condition of the same mobile phone, the RSE which does not reach the standard may occur in one time period, and the RSE which does not reach the standard may not occur in another time period, which brings certain difficulty for technicians in the field to research how to improve the RSE.

Based on this, continuing to do the investigation experiment to each part of cell-phone, we found that, when split type cassette connector set up near the antenna, the unstable contact of push rod and sliding structure can produce great harmonic to produce great RSE, when split type cassette connector set up in the position far away from the antenna, the RSE that produces is less or perhaps not produce.

It is therefore believed that a larger RSE results from the design of the card connector close to the antenna, but that the card connector is an area that needs to be located near the antenna due to certain objective conditions. Based on this, the embodiment of the application provides a card socket connector, and by making relevant improvements on the card socket connector, the RSE of the mobile phone can be effectively reduced.

Next, the embodiments of the present application will be described in detail with reference to fig. 1 to 10.

First, directions of coordinate systems in the respective drawings in the embodiments of the present application will be described. The x direction, the y direction and the z direction 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 connector.

It should be understood that the structures of each component and the connection relationships between the components shown in fig. 1 to 6 are only schematic illustrations, and should not be construed as limiting the embodiments of the present application.

Referring to fig. 1 to 6, the card socket connector 100 includes: cartridge housing 110, push rod 120, and toggle 130.

The card seat shell 110 is used for accommodating the card holder 101, the card seat shell 110 is used for being attached to a circuit board, a sliding structure 111 for accommodating the push rod 120 is arranged on a first side of the card seat shell 110, the push rod 120 can slide along the sliding structure 111, the push rod 120 or the sliding structure 111 is subjected to insulation treatment, a shift lever 130 is arranged on a second side of the card seat shell 110, the shift lever 130 is mechanically connected with the push rod 120, the shift lever 130 can be in contact with the card holder 101, the shift lever 130 can push out the card holder 101 in the sliding process of the push rod 120 along the sliding structure 111, and the first side is adjacent to the second side.

It should be noted that there are many ways to mechanically connect the shifter lever 130 to the push rod 120, and for example, a groove may be formed on the push rod 120, and an end of the shifter lever 130 is inserted into the groove to mechanically connect the shifter lever 130 to the push rod 120.

With continued reference to fig. 1, a process of the card connector 100 for taking and inserting cards will be described.

During the card taking process, the user pushes the push rod 120, the push rod 120 slides in the sliding structure 111 along the first direction shown in fig. 1, the shift lever 130 is driven by the sliding of the push rod 120 to rotate along the direction opposite to the first direction (i.e., the second direction), and the card holder 1010 is ejected along the direction opposite to the first direction (i.e., the second direction). In the card loading process, a user pushes the card holder 101 along a second direction shown in fig. 1, the card holder 101 drives the lever 130 to rotate along a direction (i.e., a first direction) opposite to the second direction, and the lever 130 drives the push rod 120 to slide in the sliding structure 111 along the direction (i.e., the first direction) opposite to the second direction, so as to implement card loading.

In the embodiment of the application, the push rod or the sliding structure is subjected to insulation treatment, so that the push rod and the sliding structure can be isolated, namely, the push rod and the card seat shell are isolated, and thus, the RSE can be effectively reduced for a mobile phone with the card seat connector arranged in an area close to an antenna.

The following describes in detail the principle of implementation of the embodiments of the present application.

In the embodiment of the application, a great deal of experiments are carried out on the existing split type card socket connector, and the problem that the RSE which is not easy to reproduce does not reach the standard is caused by the discontinuous contact between the push rod and the sliding structure for the card socket connector arranged near the antenna. The discontinuous contact means that the number of contact points and the contact force are difficult to maintain during the contact process of the components, and the discontinuous state can cause an unstable conduction state between the components. Due to the non-continuous contact, RSE obtained by testing in different time periods is different, and the problem that RSE which is not easy to reproduce does not reach the standard occurs.

Further analysis, in current split type cassette connector, the cassette shell adopts the metal material, in order to guarantee the ejecting intensity that holds in the palm of card of push rod, the push rod adopts the metal material, in order to guarantee that the push rod can normally slide, there is certain clearance between cassette shell and the push rod, this kind of clearance design makes the push rod smoothly slide in the sliding construction of cassette shell, but there is the non-stability contact on the surface of slip in-process push rod and the contact of cassette connector, there is discontinuous conduction on the surface of push rod and the contact of cassette connector promptly, because the antenna setting is in near the cassette connector again, this kind of discontinuous conduction can produce radio frequency current, thereby, arouse the RSE problem that the cell-phone is not up to standard.

Based on the above analysis, in the embodiment of the present application, the push rod or the sliding structure is subjected to insulation processing, so that the non-conduction between the push rod and the sliding structure can be realized, that is, the non-conduction between the push rod and the card seat shell is realized, so that on the premise of not changing the architecture of the mobile phone, that is, on the premise of setting the card seat connector near the antenna, the problem of unstable conduction state caused by the non-continuous contact between the push rod and the sliding structure is avoided, and the RSE is naturally reduced. In addition, the push rod is used for ejecting the card holder, so that the push rod or the sliding structure is subjected to insulation treatment, and the function of the card seat connector is not influenced.

In the embodiment of the present application, for example, the insulation treatment may be performed on the push rod or the sliding structure in 3 ways (i.e., way 1, way 2, and way 3) as follows.

Mode 1

In one possible implementation, the surface of the push rod 120 that is in contact with the sliding structure 111 is a surface coated with an insulating layer.

The surface of the push rod 120 contacting the sliding structure 111 may be the entire surface of the push rod 120 or a partial surface, and may be determined according to the sliding range between the push rod 120 and the sliding structure 111. For example, if the push rod 120 is in contact with the sliding structure 111 during the sliding process of the sliding structure 111, the surface of the push rod 120 in contact with the sliding structure 111 may be the entire surface, and the entire surface of the inner structure 122 of the push rod 120 may be coated with the insulating layer 121; if the push rod 120 is partially contacted with the sliding structure 111 during the movement of the sliding structure 111, the surface of the push rod 120 contacted with the sliding structure 111 is a partial surface of the push rod 120, and an insulating layer 121 may be coated on a partial surface of the inner structure 122 of the push rod 120.

Exemplarily, referring to (b) of fig. 4, the entire surface of the inner structure 122 of the push rod 120 is coated with the insulating layer 121, and the surface in contact with the sliding structure 211 is 121-1.

Illustratively, referring to (a) and (c) of fig. 5, the surface 122-1 of the inner structure 122 of the push rod 120 is coated with an insulating layer 123, and the surface in contact with the sliding structure 111 is the surface 123-1.

Illustratively, referring to (b) and (c) of fig. 5, the surface 122-2 of the inner structure 122 of the push rod 120 is coated with an insulating layer 124, and the surface in contact with the sliding structure 111 is the surface 124-1.

In particular implementations, the insulating layer may be sprayed on the inner structure 122 of the push rod 120 in various ways. Illustratively, the insulating layer may be electrophoretically sprayed on the inner structure 122 of the pushrod 120.

The material of the insulating layer may be any material capable of performing an insulating function, such as ceramic, teflon, or Physical Vapor Deposition (PVD) coating, and is not limited herein.

In general, it is desirable that the insulating layer adheres well to the surface of the component, and for this reason, resin may be used as a material of the insulating layer.

Mode 2

In another possible implementation, the material of the push rod 120 may be an insulating material.

Here, the insulating material of the push rod 120 may be any material capable of performing an insulating function, and is not limited herein. However, in order to make the push rod 120 have certain strength as much as possible, some materials with better strength performance, such as ceramic, graphene, and carbon fiber material, may be used.

Mode 3

In another possible implementation, the surface of the sliding structure 111 that is in contact with the push rod 120 is a surface coated with an insulating layer.

Referring to fig. 3, the surface of the sliding structure 111 contacting the push rod 120 may be, for example, a surface 111-21 of the sliding structure 111 near a region of the card socket housing 110 for accommodating the card holder, and referring to (c) of fig. 3, an inner surface of the insulating layer 111-2 is the surface 111-21, and the insulating layer 111-2 is coated on a partial region 111-1 of the sliding structure 111. Referring to fig. 6, the surface of the sliding structure 111 contacting the push rod 120 may be a surface 113-31 of the sliding structure 111 opposite to the surface 111-21, and referring to (c) of fig. 6, the inner surface of the insulating layer 11-3 is the surface 111-31, and the insulating layer 111-3 is coated on a partial region 111-4 of the sliding structure 111.

It should be understood that the region coated with the insulating layer shown in fig. 3 and 6 is only a schematic illustration, and any region contacting with the push rod may be coated with the insulating layer, and is not limited thereto.

In particular implementations, the insulating layer may be sprayed on the regions of the sliding structure 111 (e.g., regions 111-1 and/or 111-4) that contact the push rod 120 in various ways. For example, an insulating layer may be coated on a region of the sliding structure 111 contacting the push rod 120 by an electrophoretic method.

Alternatively, a resin may be employed as a material of the insulating layer.

Mode 1, mode 2, and mode 3 may be used alone, or any one of mode 1 and mode 2 may be used in combination with mode 3, that is, the push rod and the sliding structure are insulated at the same time, and the embodiment of the present application is not limited at all.

Based on the reason that the above-mentioned split type card socket connector causes the problem that RSE does not reach the standard, one solution to the problem may be to make the sliding structure in the push rod and the card socket shell non-conductive, for example: by achieving insulated contact of the push rod and the sliding structure in the cartridge housing, the RSE is reduced. Alternatively, another solution to this problem may be to achieve a stable conduction state by making the push rod and the slide structure stably contact as much as possible, and thus, the RSE can also be reduced.

Hereinafter, with reference to fig. 7 to 10, another card holder connector according to the embodiment of the present application will be described from the viewpoint of achieving stable contact between the push rod and the card holder connector. In this embodiment, the main idea of achieving stable contact of the push rod and the card holder connector is to reduce the clearance of the slide structure accommodating the push rod in the push rod and the card holder connector as much as possible in the case where ejection of the card holder can be achieved.

Fig. 7 is a schematic structural view of a card holder connector according to an embodiment of the present application, fig. 8 is a rear view of a combination of the card holder connector and a card holder according to the embodiment of the present application, fig. 9 is a sectional view of a partial area a of the card holder connector according to the embodiment of the present application on an xy plane, and fig. 10 is a schematic structural view of a card holder housing according to the embodiment of the present application.

Referring to fig. 7 to 10, the card socket connector 200 includes: a cartridge shell 210, a push rod 220, and a toggle lever 230.

The socket case 210 is used for accommodating the card holder 101, and the socket case 210 is used for being attached to a circuit board.

The first side of the cartridge housing 210 is provided with a sliding structure 211 for accommodating the push rod 220, the surface of the sliding structure 211 close to the push rod 220 is provided with at least one elastic sheet 211-0 extending towards the push rod 220, and the elastic sheet 211-0 is in pressing contact with the push rod 220 in the process that the push rod 220 slides along the sliding structure 211.

The second side of the card holder shell 210 is provided with a deflector rod 230, the deflector rod 230 is connected with the push rod 220, the deflector rod 230 is in contact with the card holder 101, the deflector rod 230 can eject the card holder 101 in the sliding process of the push rod 220 along the sliding structure 211, the first side and the second side are adjacent, and the card holder shell 210 and the push rod 220 are made of metal.

The elastic sheet 211-0 is an elastic component, has good deformability, can be denatured under the action of external force, and can be restored to the property before deformation after the external force is removed.

The elastic sheet 211-0 is in contact with the push rod 220, so that the elastic sheet 211-0 can be in pressing contact with the push rod 220 in the process that the push rod 220 slides along the sliding structure 211, on one hand, the pressing contact can enable the push rod 220 to be in stable contact with the sliding structure 211 as far as possible, and on the other hand, the good deformation capability of the elastic sheet 211-0 can enable the push rod 220 to slide in the sliding structure 211 relatively easily.

The surface of the sliding structure 211 close to the push rod 220 can be understood as the inner surface of the sliding structure 211, and the inner surface of the sliding structure 211 forms a space for accommodating the push rod 220.

The number of the elastic pieces 211-0 may be one or more, and is not limited herein. When the number of the elastic pieces 211-0 is plural, a certain gap is formed between two adjacent elastic pieces 211-0. The elastic sheet 211-0 and the sliding structure 211 may be formed by an integral molding process, or may be fixedly connected to the sliding structure 211 as an independent component, which is not limited herein.

The elastic sheet 211-0 may be disposed on any region of the inner surface of the sliding structure 211 that can contact with the push rod 220, which is not limited in this embodiment. In one possible structure design, a gap between a surface of the sliding structure 211 near the area for accommodating the card holder 101 of the card holder housing 210 and the push rod 220 may be large, and based on this, alternatively, referring to fig. 10, the elastic piece 211-0 may be disposed on the first surface 211-1 of the sliding structure 211, and the first surface 211-1 may be understood as one surface of the sliding structure near the area for accommodating the card holder 101 of the card holder housing 210.

Therefore, in the card socket connector provided by the embodiment of the application, the elastic sheet is arranged on the inner surface of the sliding structure for accommodating the push rod in the card socket shell, and the gap between the push rod and the sliding structure is reduced by using the elastic sheet, so that the elastic sheet and the push rod can be in pressing contact in the process that the push rod slides along the sliding structure, and the push rod and the sliding structure can be in stable contact as far as possible, and the RSE generated by equipment can be reduced even if the push rod and the sliding structure are conducted; in addition, the elastic sheet has better deformation characteristics, so that the push rod can slide in the sliding structure even if the push rod is in contact with the sliding structure.

In order to achieve a better stable contact between the push rod and the sliding structure, optionally, with continued reference to fig. 9, the surface of the sliding structure 211 opposite to the first surface 211-1 is provided with at least one convex hull 211-3, and the convex hull 211-3 is in pressing contact with the push rod 220 during the sliding of the push rod 220 along the sliding structure 211.

The number of convex hulls 211-3 may be one or more, and is not limited herein. When the number of the convex hulls 211-3 is plural, a certain gap is provided between adjacent two convex hulls 211-3.

The convex hull 211-3 may realize a point contact between the sliding structure 211 and the push rod 220, and may better realize a stable contact between the push rod 220 and the sliding structure 211 than a surface contact manner.
