[0001] The present application relates to the technical field of electronic products, and in particular to a card holder, a card tray and a smart terminal. Background Art

[0002] With the development of communication technology, the functions of smart terminals such as mobile phones are constantly enriched, which puts higher requirements on card holders. Usually, a card tray is used to load a chip card (such as a SIM card), and then the card tray is installed in the card holder set inside the smart terminal. The spring in the card holder contacts and conducts with the contacts of the chip card to realize the information reading and communication functions of the chip card.

[0003] In the process of conceiving and implementing this application, the inventor found that there are at least the following problems: during the insertion and removal of the card holder, the spring piece is prone to serious wear and tear, which affects the service life of the card holder and causes unstable communication quality.

These drawings and textual descriptions are not intended to limit the scope of the concept of this application in any way, but to illustrate the concept of this application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0075] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0076] It should be noted that, in this article, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. Optionally, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context in the specific embodiment.

[0077] It should be understood that, although the terms first, second, third, etc. may be used to describe various information in this article, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of this article, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determination". Furthermore, as used in this article, the singular forms "one", "one" and "the" are intended to also include plural forms, unless there is an opposite indication in the context. It should be further understood that the terms "comprising", "including" indicate that there are the above-mentioned features, steps, operations, elements, components, projects, kinds, and / or groups, but do not exclude the existence, occurrence or addition of one or more other features, steps, operations, elements, components, projects, kinds, and / or groups. The terms "or", "and / or", "including at least one of the following" etc. used in this application may be interpreted as inclusive, or mean any one or any combination. For example, “comprising at least one of the following: A, B, C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”, and for another example, “A, B or C” or “A, B and / or C” means “any of the following: A; B; C; A and B; A and C; B and C; A and B and C”. An exception to this definition will only occur when a combination of elements, functions, steps or operations are inherently mutually exclusive in some manner.

[0078] It should be understood that, although the various steps in the flowchart in the embodiment of the present application are displayed in sequence according to the indication of the arrows, these steps are not necessarily performed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and it can be performed in other orders. Moreover, at least a portion of the steps in the figure may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily performed at the same time, but can be performed at different times, and their execution order is not necessarily performed in sequence, but can be performed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.

[0079] As used herein, the words "if" and "if" may be interpreted as "at the time of" or "when" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrases "if it is determined" or "if (stated condition or event) is detected" may be interpreted as "when it is determined" or "in response to determining" or "when detecting (stated condition or event)" or "in response to detecting (stated condition or event)", depending on the context.

[0080] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0081] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0082] Smart terminals such as mobile phones need to be loaded with chip cards in the card tray. Chip cards may include but are not limited to Subscriber Identity Module (SIM) cards and Secure Digital (SD) cards. SIM cards can store digital mobile phone customer information, encryption keys, and user phone books, etc., for user identity authentication and to encrypt voice information during calls. SD cards are commonly used memory cards that can expand the storage space of information inside smart terminals.

[0083] The SIM card has metal contacts. The spring inside the card holder contacts and conducts with the metal contacts of the SIM card to realize the information reading and communication functions of the SIM card. Usually, the contacts on the SIM card are arranged in three rows, and the conductive terminal of one spring is connected to one contact. Figure 1 As shown, on the SIM card, the first row of contacts are defined as a first contact 51, a second contact 52, and a third contact 53, respectively.

[0084] In the related art, the direction in which the card tray 40 is inserted and removed from the card holder is consistent with the contact arrangement direction of the SIM card. Figure 1 The arrow X in the figure indicates the direction, and the spring that is in contact with the metal contact of the SIM card is located on the same surface. Figure 1 As shown, when the card tray 40 carrying the first SIM card 71 and the second SIM card 72 is inserted into the card holder, the third contact 53 of the first SIM card 71 will scrape the first terminal 731, the second terminal 732, the third terminal 733, the fourth terminal 734, the fifth terminal 735, the sixth terminal 736 and the seventh terminal 737 in sequence, and when the card tray 40 is pulled out, the scraping contact will be repeated in the reverse direction. In this single insertion and removal action, the third contact 53 of the first SIM card 71 is scraped 14 times. Optionally, the first terminal 731, the second terminal 732, and the third terminal 733 are all used to contact and conduct with the contact of the second SIM card 72, the fourth terminal 734 is used to contact and conduct with the contact of the SD card 74, and the fifth terminal 735, the sixth terminal 736 and the seventh terminal 737 are all used to contact and conduct with the contact of the first SIM card 71.

[0085] By analogy, in a single insertion and removal action of the card tray 40: the second contact 52 and the first contact 51 of the first SIM card 71 are scratched 12 times and 10 times respectively, the first conductive part 741 of the SD card 74 is scratched 8 times, and the second contact 52 of the second SIM card 72 is scratched 4 times. It can be seen that the scratch life of the three cards is: the first SIM card 71 < SD card 74 < the second SIM card 72, and the hidden danger of the three cards being broken due to the generation of stolen goods due to scratching increases. In addition, due to multiple scratches, the service life of the spring in the card holder will also be affected.

[0086] The application provides a card holder, which can have an angle between the insertion and removal direction of the card tray and the arrangement direction of the first spring sheets in each row of first spring sheets, so that the first spring sheets in each row of first spring sheets are no longer on the active path of the contacts corresponding to the non-first chip card. During the insertion and removal of the card tray, each first spring sheet can be effectively prevented from contacting the contacts of the non-corresponding first chip card, reducing the number of times the first spring sheet is scratched by the contacts of the first chip card, thereby reducing the wear of the first spring sheet and the first chip card, so that the service life of the card holder and the first chip card can be improved, ensuring the communication quality. The following describes a card holder, a card tray and a smart terminal provided by an embodiment of the application with reference to the accompanying drawings.

[0087] First embodiment

[0088] refer to Figure 2 and Figure 3 As shown, the embodiment of the present application provides a card holder, including: a card holder body 10 and an electrical connection assembly, wherein the card holder body 10 has a card slot 13, a card tray 40 is inserted and removed in the card slot 13 along a first direction, and the card tray 40 is at least used to carry a first chip card 50; the electrical connection assembly is arranged on the inner wall surface of the card slot 13, and the electrical connection assembly includes at least one first spring sheet group 20, and the first spring sheet group 20 includes at least one row of first spring sheets 21 arranged along a second direction, and the first spring sheets 21 abut against the contacts of the first chip card 50. There is an angle between the second direction and the first direction, so that each first spring sheet 21 avoids the contacts of the non-corresponding first chip card 50 during the insertion and removal of the card tray 40.

[0089] In this example, the first direction reference Figure 3 The direction indicated by the arrow X in the second direction is Figure 3 The first chip card 50 may be a SIM card, for example.

[0090] refer to Figure 3 and Figure 4As shown, a card socket provided by the present application has an angle between the second direction and the first direction, that is, there is an angle between the insertion and removal direction of the card tray 40 and the arrangement direction of the first spring pieces 21 in each row of the first spring pieces 21. Therefore, the first spring pieces 21 in each row of the first spring pieces 21 are no longer on the active path of the non-corresponding contacts of the first chip card 50. During the insertion and removal of the card tray 40, the first spring pieces 21 can be effectively prevented from contacting the contacts of the non-corresponding first chip card 50, reducing the number of times the first spring pieces 21 are scratched by the contacts of the first chip card 50, thereby reducing the wear of the first spring pieces 21 and the first chip card 50, so that the service life of the card socket and the first chip card 50 can be improved, thereby ensuring the communication quality.

[0091] In one possible implementation, reference Figure 3 and Figure 4 As shown, the angle θ between the second direction and the first direction satisfies: 5°≤θ≤25°. The larger the angle θ is, the more conducive it is to preventing the first spring piece 21 from scratching the non-corresponding first chip card 50. However, the angle θ cannot be too large, otherwise it will increase the width space occupied by the card holder, which is not conducive to the miniaturization of the card holder.

[0092] In one possible implementation, the angle θ between the second direction and the first direction can be, for example, 5°, 5.5°, 6.3°, 7.5°, 8°, 10°, 10.5°, 12°, 13.5°, 15°, 16.8°, 18°, 20°, 21.2°, 22° or 25°, etc.

[0093] In a possible implementation, the first spring sheet group 20 includes two rows of first spring sheets 21 arranged along the second direction, each first spring sheet 21 correspondingly abuts against each contact of the first chip card 50, and the first spring sheet group 20 also includes a connecting portion 22, and each first spring sheet 21 is connected as a whole through the connecting portion 22.

[0094] Optionally, the first spring sheet group 20 may continue to use the existing structure, and only the installation angle of the first spring sheet group 20 is changed to achieve the purpose of adjusting the angle between the second direction and the first direction.

[0095] In a possible implementation, the first spring piece 21 is made of a conductive metal, such as an aluminum sheet, a copper sheet, etc., and the connecting portion 22 is made of a conductive metal, such as an aluminum sheet, a copper sheet, etc.

[0096] In a possible implementation, the first spring piece 21 is V-shaped, the V-shape has an opening, the connecting portion 22 is sheet-shaped, a hollow hole is opened in the connecting portion 22, and the connecting portion 22 has at least two inner welding legs extending into the hollow hole, the number of the inner welding legs is consistent with the number of the first spring pieces 21, and the position of each inner welding leg corresponds to the position of each first spring piece 21, so that the connecting portion 22 is electrically connected to each first spring piece 21 through corresponding welding of each inner welding leg, thereby ensuring the stability of the overall structure of the first spring piece group 20. For example, each inner welding leg is connected to the opening of the V-shape, so that the structure of the card holder is compact and the space occupancy rate is reduced.

[0097] Optionally, refer to Fig.28 As shown, the connecting portion 22 of the first spring sheet assembly 20 may also be in other shapes.

[0098] In a possible implementation, in the first row, the first elastic pieces 21 arranged along the second direction respectively have a first contact point 211, a second contact point 212, and a third contact point 213, wherein the first contact point 211, the second contact point 212, and the third contact point 213 are arranged along the second direction. In the second row, the first elastic pieces 21 arranged along the second direction respectively have a fourth contact point 214, a fifth contact point 215, and a sixth contact point 216, and optionally, the fourth contact point 214, the fifth contact point 215, and the sixth contact point 216 are arranged along the second direction. Optionally, the first chip card 50 includes two rows of contacts, the first row of contacts includes the first contact point 51, the second contact point 52, and the third contact point 53 arranged along the second direction, and the second row of contacts includes the fourth contact point 54, the fifth contact point 55, and the sixth contact point 56 arranged along the second direction.

[0099] When the card tray 40 is installed in the card slot 13: the first contact point 211 and the first contact point 51 abut against each other to achieve conduction, the second contact point 212 and the second contact 52 abut against each other to achieve conduction, the third contact point 213 and the third contact 53 abut against each other to achieve conduction, the fourth contact point 214 and the fourth contact 54 abut against each other to achieve conduction, the fifth contact point 215 and the fifth contact 55 abut against each other to achieve conduction, and the sixth contact point 216 and the sixth contact 56 abut against each other to achieve conduction.

[0100] Since there is an angle between the insertion and removal direction of the card tray 40 and the arrangement direction of the first elastic sheets 21 in each row of the first elastic sheets 21, during the insertion and removal of the card tray 40 in the card slot 13 along the first direction, the first contact point 211 only contacts the first contact point 51, thereby avoiding the first contact point 211 from contacting the second contact point 52 and the third contact point 53, and avoiding the first contact point 211 from scratching the second contact point 52 and the third contact point 53, thereby reducing the wear of the first contact point 211. Optionally, the second contact point 212 can also be avoided from contacting the first contact point 51 and the third contact point 53, thereby reducing the phenomenon that the second contact point 212 scratches the first contact point 51 and the third contact point 53, thereby reducing the wear of the second contact point 212, which is beneficial to improving the service life of the first chip card 50 and the first elastic sheet group 20. The situation in which the third contact point 213, the fourth contact point 214, the fifth contact point 215, and the sixth contact point 216 are scratched is similar, and will not be repeated here.

[0101] In one possible implementation, reference Figure 5 and Figure 6 As shown, the electrical connection assembly further includes a second spring sheet group 30 , and the second spring sheet group 30 includes at least one row of second spring sheets 31 . The second spring sheets 31 are used to contact with the contacts of the second chip card 60 carried by the card tray 40 .

[0102] Optionally, the second chip card 60 may be a Secure Digital (SD) card.

[0103] Optionally, the second spring sheet group 30 is arranged on the inner wall surface of the slot 13, and the second spring sheet group 30 includes at least one row of second spring sheets 31 arranged at intervals. The second spring sheets 31 can be arranged at intervals along the third direction, and the third direction is referenced to Figure 6 In the direction indicated by the arrow Z in FIG. 4 , the number of the second spring pieces 31 is consistent with the number of the contacts of the second chip card 60 , and each second spring piece 31 is used to contact with each contact of the second chip card 60 carried by the tray 40 .

[0104] The second spring sheet group 30 and the first spring sheet group 20 are arranged in the slot 13 at least partially without overlapping, which can effectively prevent the second spring sheet group 30 and the first spring sheet group 20 from interfering with each other, and also help to make the second spring sheet group 30 and the first spring sheet group 20 relatively independent and not affect each other.

[0105] In one possible implementation, reference Figure 3 As shown, the card holder body 10 includes a bottom plate 11 and a card cover 12 , a card slot 13 is formed between the card cover 12 and the bottom plate 11 , the card cover 12 includes a cover plate 121 and a side plate 122 arranged at the edge of the cover plate 121 , and the side plate 122 is connected to the bottom plate 11 .

[0106] In one possible implementation, the base plate 11 may be a printed circuit board (PCB) to facilitate connecting the electrical connection components to the corresponding printed circuit, and finally to electrically connect to the chip card through the card holder to read the information stored in the chip card.

[0107] In one possible implementation, the cover plate 121 is roughly rectangular, and side panels 122 are provided on three side edges of the cover plate 121. No side panel 122 is provided on one side edge of the cover plate 121 along the first direction, thereby forming an opening of the card slot 13 between one side of the cover plate 121 along the first direction and the bottom plate 11. The opening of the card slot 13 is a channel for the card tray 40 to enter the card slot 13, which facilitates the card tray 40 to be inserted into the card slot 13 from the opening along the first direction.

[0108] In a possible implementation, the side panel 122 may be connected to the bottom panel 11 by welding. Of course, the side panel 122 may also be connected to the bottom panel 11 by screw connection, snap connection or other methods.

[0109] In one possible implementation, reference Figure 3 and Figure 4 As shown, there are at least two first spring leaf groups 20 , each of which is independently disposed on the inner wall surface of the slot 13 , and the first spring leaf group 20 and the second spring leaf group 30 are independently disposed.

[0110] In this embodiment, the first spring leaf groups 20 do not need to be connected by a mechanical structure, and any one of the first spring leaf groups 20 can be removed independently without affecting the operation of the other first spring leaf groups 20. When the first spring leaf group 20 is damaged, it is convenient to remove and replace the damaged first spring leaf group 20 without replacing the entire card holder, which helps to save costs and is more economical and environmentally friendly.

[0111] In a possible implementation, the edge of the card cover 12 has a pin 123 electrically connected to the base plate 11 , and the electrical connection component located on the card cover 12 is electrically connected to the pin 123 .

[0112] In a possible implementation, the pin 123 may be located at an edge of the side plate 122 of the card cover 12 , and the pin 123 may be electrically connected to the base plate 11 by welding, thereby achieving electrical connection between the electrical connection component and the base plate 11 .

[0113] In a possible implementation, the electrical connection component located on the bottom plate 11 is electrically connected to the bottom plate 11. The electrical connection component located on the bottom plate 11 may be electrically connected to the bottom plate 11 by welding. When the electrical connection component fails and needs to be disassembled and replaced, the weld marks formed by the welding of the electrical connection component and the bottom plate 11 are hot-melted to achieve the disassembly and replacement of the electrical connection component.

[0114] In one possible implementation, reference Fig. 22 , Fig.23 and Fig.24 As shown, when the second spring sheet group 30 is arranged on the inner wall surface of the cover plate 121 of the card cover 12, a support member 80 is also arranged on the base plate 11. The support member 80 is located directly below the second spring sheet 31 of the second spring sheet group 30, and there is a distance between the support member 80 and the second spring sheet 31 of the second spring sheet group 30.

[0115] Since there is a gap between the second chip card 60 and the bottom plate 11, after the card tray is installed in the card slot 13, the second chip card 60 is easily deformed by the elastic extrusion of the second spring group 30, so that the second chip card 60 is slightly deformed in a local position toward the bottom plate 11, which is not conducive to the insertion and removal of the card tray. In this embodiment, the support member 80 can be provided to support the second chip card 60. After the card tray is installed in the card slot 13, the support member 80 can prevent the second chip card 60 from being squeezed and deformed by fatigue, which helps to prevent fine lines from being generated inside the second chip card 60, thereby ensuring the service life of the second chip card 60 and making the insertion and removal of the card tray smoother and unobstructed.

[0116] In a possible implementation, the side of the support member 80 facing the second spring sheet 31 also has two protrusions, which respectively correspond to the positions of the first and last second spring sheets 31 in a row of second spring sheets 31, thereby helping to improve the support for the second chip card 60.

[0117] In a possible implementation, the support member 80 may be processed on the bottom plate 11 by surface mounting technology (SMT for short). The support member 80 may be a steel sheet, for example.

[0118] Second embodiment

[0120] When the card tray is inserted into the card socket, the contacts of the first chip card 50 are in contact with the first spring sheets 21 of the first spring sheet group 20 , thereby achieving electrical conduction and meeting communication requirements.

[0121] In this embodiment, in the process of inserting the card tray into the above-mentioned card socket along the first direction, or in the process of taking the card tray out of the card socket along the first direction, the contact and scratching between the contacts of the first chip card 50 and the first spring pieces 21 of the non-corresponding first spring piece group 20 can be reduced, thereby effectively reducing the problem of damage to the first spring piece group 20 and the first chip card 50, which helps to improve the service life of the first spring piece group 20 and the first chip card 50.

[0122] In one possible implementation, the card tray 41 also includes a second accommodating groove 44, which is used to accommodate a second chip card 60, and the contacts of the second chip card 60 correspond to the second spring piece group 30 of the card seat; along the thickness direction of the card tray, along the thickness direction of the card tray, the projection of at least part of the first accommodating groove 43 coincides with the projection of at least part of the second accommodating groove 44.

[0123] In this embodiment, the first chip card 50 and the second chip card 60 can share at least part of the area of ​​the card tray, and the arrangement of the first chip card 50 and the second chip card 60 is more compact, thereby improving the space utilization of the card tray, which is beneficial to shortening the length of the card tray 40 along the first direction and the length of the card seat along the first direction.

[0124] In one possible implementation, reference Figure 7 and Figure 8 As shown, one end of the card holder 41 along the first direction is connected to a door plate 42. When the card holder 40 is inserted into the above-mentioned card holder along the first direction, the door plate 42 abuts against the open end of the card slot 13 to play a limiting role.

[0125] The first receiving groove 43 is a hollow hole, which can expose the two sides of the first chip card 50. The side wall of the first receiving groove 43 has a ridge that defines the position of the first chip card 50, and the ridge also plays a role in supporting the first chip card 50. The second receiving groove 44 is a hollow hole, which can expose the two sides of the second chip card 60. The side wall of the second receiving groove 44 has a ridge that defines the position of the second chip card 60.

[0126] In a possible implementation, the card bracket 41 may be made of plastic.

[0127] The card tray provided in this embodiment can determine the position, type and number of cards to be placed according to specific actual usage requirements.

[0130] In a possible implementation, the two first spring sheet groups 20 may be disposed on the bottom plate 11 at intervals along the first direction, and the second spring sheet group 30 is disposed on the card cover 12 .

[0131] In one possible implementation, the second spring sheet group 30 is arranged on the cover plate 121 of the card cover 12, and the two ends of the second spring sheet 31 in the length direction are connected to the inner wall surface of the cover plate 121. The middle part of the second spring sheet 31 in the length direction is arched toward the direction close to the base plate 11, so that when the card tray 40 is inserted and pulled out in the card slot 13 along the first direction, the middle part of the second spring sheet 31 in the length direction is elastically deformed and contacts one by one with the contacts of the second chip card 60.

[0132] In a possible implementation, the first spring sheet group 20 includes but is not limited to being arranged on the bottom plate 11 by welding, snap connection, or screw connection. Each first spring sheet group 20 is a relatively independent structure, and one of the two first spring sheet groups 20 can be independently disassembled and replaced, while the operation of the other first spring sheet group 20 of the two first spring sheet groups 20 will not be affected. It is convenient to disassemble and replace the damaged first spring sheet group 20, which helps to save costs.

[0133] In the card tray used in the card holder provided by the present embodiment, there are two first receiving grooves 43, which are arranged at intervals along the first direction, and in the thickness direction of the card tray, a partial projection of at least one of the two first receiving grooves 43 overlaps with a projection of at least a portion of the second receiving groove 44. The second receiving groove 44 partially overlaps with the first receiving groove 43, which helps to improve the space utilization of the card tray.

[0134] The two first accommodating grooves 43 and the second accommodating grooves 44 are located on the same surface of the card bracket 41. The first accommodating groove 43 is used to accommodate the first chip card 50, and the second accommodating groove 44 is used to accommodate the second chip card 60. The openings of the first accommodating groove 43 and the second accommodating groove 44 are both located on the first surface 411 of the card bracket, that is, the upper surface of the card bracket. With such a structure, when the first chip card 50 is installed in the first accommodating groove 43 and the second chip card 60 is installed in the second accommodating groove 44, the first chip card 50 and the second chip card 60 can be prevented from falling off.

[0135] In the Figure 8 and Fig. 9After the card tray shown is inserted into the card slot 13 of the card holder body 10, the contacts of the two first chip cards 50 are all facing the base plate 11, and the contacts of the second chip card 60 are all facing the cover plate 121, so as to facilitate electrical conduction and read the data information stored in the first chip card 50 and the second chip card 60.

[0136] refer to Figure 2 and Figure 3 As shown, the card holder provided in this embodiment can carry two first chip cards 50 and one second chip card 60. When in use, one chip card can be selected to be installed from the two first chip cards 50 and one second chip card 60, a total of three chip cards, or any two chip cards can be selected to be installed from the three chip cards.

[0137] refer to Figure 4 As shown, during the operation of inserting the card tray 40 into the card slot 13, the third contact 53 of the first chip card 50 far from the door panel 42 is scratched by the third contact points 213 of the two first spring leaf groups 20, and is scratched twice in total. During the operation of removing the card tray 40 from the card slot 13, the third contact 53 of the first chip card 50 far from the door panel 42 is also scratched by only the third contact points 213 of the two first spring leaf groups 20, so it is only scratched four times in a single insertion and removal movement. By analogy, in a single insertion and removal movement of the card tray 40, the first contact 51 and the second contact 52 of the first chip card 50 far from the door panel 42 are also scratched four times.

[0138] The third contact 53 of the first chip card 50 near the door panel 42 is only scratched by one third contact point 213. Therefore, in a single insertion and removal movement, the third contact 53 of the first chip card 50 near the door panel 42 is only scratched twice. Similarly, in a single insertion and removal movement of the card tray 40, the first contact 51 and the second contact 52 of the first chip card 50 near the door panel 42 are also scratched twice.

[0139] It can be seen that the present application can significantly reduce the damage caused by scratching and abrasion, increase the service life of the first chip card 50 and the first spring assembly 20, and reduce the occurrence of circuit breakage caused by dirt on the first chip card 50 due to scratching.

[0140] In this embodiment, the contacts of the second chip card 60 face the cover plate 121 of the card cover 12, and the contacts of the first chip card 50 face the bottom plate 11, so that during the insertion and removal of the card tray, the contacts of the second chip card 60 only contact the second elastic pieces 31 that are in contact and conductive with the corresponding contacts, thereby preventing the contacts of the second chip card 60 from contacting the first elastic pieces 21 of the first elastic piece group 20. Therefore, during a single insertion and removal movement of the card tray 40, the contacts of the second chip card 60 are scratched twice, so that the life of the second chip card 60 will not be affected by the scratches of the first elastic piece group 20, thereby improving the service life and stability of the second chip card 60.
