Description

Technical Field

[0001] This application belongs to the field of communication equipment technology, specifically relating to a card connector and an electronic device. Background Technology

[0002] In the field of communication equipment technology, to facilitate the operation of electronic devices, most electronic devices currently include a card connector, which consists of a card tray and a card socket. Users insert cards into the internal cavity of the electronic device through the card tray, making it easy to replace cards. These cards can be Subscriber Identification Module (SIM) cards, Trans-flash Cards (TF) cards, etc. The card socket is typically located within the internal cavity of the electronic device, enabling the card to electrically connect to the device. During the assembly process, when the card is inside the electronic device, it is electrically connected to the card socket within the cavity, thereby enabling information transmission and other functions.

[0003] In related technologies, the end of the card holder is provided with a functional device. When the card tray is inserted into the card holder, the card tray and the functional device are spaced apart along the length of the card tray. Therefore, the dimensions of the card tray and the functional device are relatively long, and the card holder needs to reserve a space for the installation of the functional device. Therefore, the length dimension of the card holder is also relatively large.

[0004] Taking the ejection mechanism as an example, the ejection mechanism is used to eject the card tray. The ejection end of the ejection mechanism is usually located at the end of the card holder. When the card tray is inserted into the card holder, the end of the card tray is positioned opposite to the ejection end of the ejection mechanism. At this time, the length of the component formed by the ejection mechanism and the card tray is relatively long, and the card holder needs to reserve a space for the installation of the ejection mechanism. Therefore, the length dimension of the card holder is also relatively large, resulting in a relatively long overall length of the card connector. This causes the card connector to occupy a large installation space in the electronic device, which is not conducive to the thinning and lightening of the electronic device. Summary of the Invention

[0005] The purpose of this application is to provide a card connector and an electronic device that can solve the problem of card connectors occupying a large installation space in electronic devices.

[0006] To solve the above-mentioned technical problems, this application is implemented as follows: This application provides a card connector, including a card holder, a card tray, and an ejection mechanism; The card tray has an insertion end and an exposed end. The card tray has a first card slot and a receiving space. The receiving space is located between the insertion end and the first card slot. The insertion end and the exposed end are arranged along the width direction of the first card slot. The card tray is provided with a limiting beam, the first card slot is separated from the receiving space by the limiting beam, and an elastic arm is formed on the side of the limiting beam near the first card slot. The ejection mechanism is disposed on the card holder, and when the card tray is inserted into the card holder, a portion of the ejection mechanism is located within the receiving space.

[0007] This application provides an electronic device including the card connector described above.

[0008] In this embodiment, the card tray has a receiving space located between the insertion end and the first card slot. When the card tray is inserted into the card holder, a portion of the ejection mechanism on the card holder can be located within the receiving space. The ejection mechanism is recessed a certain distance towards the exposed end of the card holder at its mounting position, thus shortening the overall length of the card tray and the ejection mechanism, and correspondingly shortening the length of the card holder. Furthermore, to further shorten the card connector, this application also improves the first card slot and the spring arm. The insertion end and the exposed end are arranged along the width direction of the first card slot. The first card slot is then laterally positioned on the card tray. Therefore, in the direction from the exposed end of the card tray to the insertion end, the first card slot occupies a smaller portion of the card tray's dimensions. The card tray can reserve more space at the insertion end by moving the limiting beam towards the area closer to the exposed end. This space can be used to increase the volume of the receiving space. Meanwhile, this application forms the elastic arm on the limiting beam, which can significantly reduce the width of the card tray, and the force of the ejection mechanism acting on the limiting beam can more effectively clamp the card located in the first card slot through the elastic arm, preventing the card from falling out or shifting.

Detailed Implementation

[0011] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0012] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0013] The card connector and electronic device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0014] Please refer to Figures 1 to 13 This application discloses a card connector that is used in electronic devices. The disclosed card connector includes a card holder 200, a card tray 100, and an ejection mechanism 300.

[0015] Card holder 100 is used to carry cards, which can be Subscriber Identification Module (SIM) cards, Trans-flash Cards (TF) cards, etc.

[0016] Card slot 200 is typically located inside the cavity of an electronic device, enabling electrical connection between the card and the device. When a card is inserted into card slot 200 via card tray 100, the card and card slot 200 are electrically connected, thereby enabling functions such as information transmission.

[0017] Card tray 100 has an insertion end 101 and an exposed end 102. Card tray 100 is inserted into card holder 200 through insertion end 101. When card tray 100 is inserted into card holder 200, exposed end 102 is exposed outside card holder 200 and also exposed to electronic device. Card tray 100 has a first card slot 103 and a receiving space 105, the receiving space 105 being located between insertion end 101 and first card slot 103.

[0018] An ejection mechanism 300 is provided in the card holder 200 and is used to eject the card tray 100 when a card is ejected. When the card tray 100 is inserted into the card holder 200, part of the ejection mechanism 300 is located within the receiving space 105.

[0019] Specifically, the card holder 200 has a first end 201 and a second end 202. The arrangement direction of the first end 201 and the second end 202 is parallel to the arrangement direction of the exposed end 102 and the insertion end 101. When the card tray 100 is inserted into the card holder 200, the first end 201 corresponds to the exposed end 102, and the second end 202 corresponds to the insertion end 101. A portion of the ejection mechanism 300 is disposed at the second end 202 of the card holder 200.

[0020] The ejection mechanism 300 may include an ejector rod 310, a rotating rod 320, and a rotating shaft 330. The ejector rod 310 may be disposed on one side of the card holder 200. The ejector rod 310 may be disposed along the length direction of the card holder 100, or its extension direction may be parallel to the arrangement direction of the insertion end 101 and the exposed end 102. The rotating rod 320 may be disposed at the second end 202 of the card holder 200. The card holder 200 and the rotating rod 320 are rotatably connected via the rotating shaft 330. One end of the rotating rod 320 is rotatably connected to the ejector rod 310, and the other end of the rotating rod 320 may be a free end. The rotating shaft 330 is located between the two ends of the rotating rod 320. When the card holder 100 is inserted into the card holder 200, at least a portion of the rotating rod 320 and the rotating shaft 330 are located within the receiving space 105.

[0021] When the card is ejected, the push rod 310 is moved, and the push rod 310 drives the rotating rod 320 to rotate. The rotating rod 320 abuts against the card holder 100, thereby pushing the card holder 100 out of the card seat 200.

[0022] In the embodiments disclosed in this application, the card tray 100 has a receiving space 105, which is located between the insertion end 101 and the first card slot 103. When the card tray 100 is inserted into the card holder 200, a portion of the ejection mechanism 300 disposed on the card holder 200 can be located within the receiving space 105. The ejection mechanism 300 is recessed a certain distance towards the exposed end 102 of the card holder 200 at the installation position of the card holder 200, thus shortening the overall length of the card tray 100 and the ejection mechanism 300, and also shortening the length of the card holder 200 accordingly, thereby shortening the overall length of the card connector. This results in the card connector occupying less installation space in the electronic device, which is beneficial to the development of thinner and lighter electronic devices.

[0023] To further increase the volume of the receiving space 105, the technical solution disclosed in this application also improves the first card slot 103. The insertion end 101 and the exposed end 102 are arranged along the width direction of the first card slot 103. In this solution, the first card slot 103 is laterally disposed on the card holder 100. Therefore, in the direction from the exposed end 102 of the card holder 100 to the insertion end 101, the first card slot 103 occupies a smaller size in the card holder 100, and a portion of space can be reserved in the area of ​​the card holder 100 near the insertion end 101. This portion of space can be used to increase the volume of the receiving space 105.

[0024] In the above embodiment, the length of the first card slot 103 is greater than the width of the first card slot 103. Therefore, the arrangement of the insertion end 101 and the exposed end 102 along the width direction of the first card slot 103 is less than the arrangement of the insertion end 101 and the exposed end 102 along the length direction of the first card slot 103. This results in the first card slot 103 occupying less space in the card tray 100 along the direction of the insertion end 101 and the exposed end 102, thus allowing a larger area on the card tray 100 to be used for the receiving space 105. Simultaneously, since a larger space can be reserved at the insertion end 101 of the card tray 100, the width of the limiting beam 120 can be increased while increasing the receiving space 105, thereby improving the strength of the limiting beam 120.

[0025] The above scheme can be understood as follows: the first card slot 103 is laterally disposed on the card holder 100. Here, "laterally disposed" means that the angle between the width direction of the first card slot 103 and the length direction of the card holder 100 can be greater than or equal to 0° and less than 90°. Preferably, the angle between the width direction of the first card slot 103 and the length direction of the card holder 100 is equal to 0°. In this case, the length direction of the first card slot 103 is perpendicular to the length direction of the card holder 100.

[0026] Furthermore, a spring arm 1211 is formed on one side of the first card slot 103. The spring arm 1211 is used to limit the card inserted into the first card slot 103, thereby preventing the card from falling out of the first card slot 103.

[0027] During the assembly process, the user presses the elastic arm 1211 to deform it, thereby increasing the opening of the first card slot 103. Then, the card is inserted into the first card slot 103, and the pressure on the elastic arm 1211 is removed. The elastic arm 1211 returns to its elasticity, thereby limiting the card and preventing the card from falling out of the first card slot 103.

[0028] To further reduce the size of the card tray, this application provides a spring arm 1211 on the side of the limiting beam 120 near the first card slot 103. In this design, the spring arm 1211 is formed on the limiting beam 120, which can reduce the width of the card tray.

[0029] The solution disclosed in this application, by laterally arranging the first card slot 103 on the card tray 100 and placing the elastic arm 1211 on the limiting beam 120 near the insertion end, can increase the receiving space 105 while reducing the overall length and width of the card connector. When the card tray 100 is inserted into the card holder 200, the ejection mechanism 300 is almost completely received within the receiving space 105, thereby significantly shortening the overall length of the card connector. This results in the card connector occupying less installation space in the electronic device, which is more conducive to the development of thinner and lighter electronic devices.

[0030] Optionally, the card holder 100 may include a support plate 110, a first limiting beam 141, a second limiting beam 142, a third limiting beam, and a fourth limiting beam 144. The first limiting beam 141, the second limiting beam 142, the third limiting beam, and the fourth limiting beam 144 can be connected end to end in sequence, forming a first card slot 103 with the support plate 110. The first limiting beam 141 and the third limiting beam can be arranged along the width direction of the first card slot 103, where the third limiting beam is the limiting crossbeam 120 mentioned above. The second limiting beam 142 and the fourth limiting beam 144 can be distributed along the length direction of the first card slot 103.

[0031] In the above embodiment, the elastic arm 1211 is disposed on the limiting beam 120 disposed in the width direction of the first card slot 103, thereby making the width of the second limiting beam 142 or the fourth limiting beam 144 along the length direction of the first card slot 103 smaller, thus making the width of the card holder 100 smaller. At the same time, since the first card slot 103 is arranged laterally, space can be reserved for the placement of the elastic arm 1211, so the width of the card holder 100 can be reduced without increasing the length of the card holder 100, thereby reducing the overall volume of the card holder 100.

[0032] In the above embodiment, the elastic arm 1211 is formed on the limiting beam 120. Compared with the solution where the elastic arm 1211 is formed on the first limiting beam 141, when the elastic arm 1211 is formed on the first limiting beam 141, the elastic arm 1211 occupies a space between the first limiting beam 141 and the first slot 103. Therefore, the opening position of the first slot 103 needs to be moved a certain distance toward the insertion end 101, that is, the first slot 103 is moved backward. At this time, the backward movement of the first slot 103 will cause the receiving space 105 to move backward, so that the first slot 103 will occupy the position of the receiving space 105, thereby affecting the volume of the receiving space 105. In this application, the elastic arm 1211 is formed on the limiting beam 120. At this time, the first card slot 103 moves a certain distance away from the side opposite to the insertion end 101, thereby bringing the opening position of the first card slot 103 closer to the exposed end 102. Therefore, a larger space can be reserved on the side of the card tray 100 near the insertion end 101, that is, the first card slot 103 is moved forward. At this time, the forward movement of the first card slot 103 will cause the receiving space 105 to move forward, thereby making the volume of the receiving space 105 larger, which can further shorten the overall length of the card tray 100 and the ejection mechanism 300, and further reduce the installation space occupied by the card connector in the electronic device.

[0033] In another optional embodiment, the card connector disclosed in this application may further include a card tray insertion detection mechanism 400. The card tray insertion detection mechanism 400 is used to detect whether the card tray 100 is inserted into the card holder 200, thereby ensuring that the card tray 100 is inserted correctly and preventing the card tray 100 from falling out of the card holder 200 if it is not properly inserted, thus preventing damage to the card tray 100. This refers to detecting whether the card tray 100 is inserted into a preset position in the card holder 200. The preset position refers to the position where the card on the card tray 100 is electrically connected to the card holder 200, or the position where the card tray 100 is clamped and fixed to the card holder 200.

[0034] The card tray insertion detection mechanism 400 can be disposed in the card holder 200. When the card tray 100 is inserted into the card holder 200, at least a portion of the card tray insertion detection mechanism 400 is located within the receiving space 105. In this solution, when the card tray is inserted into the card holder 200, at least a portion of the card tray insertion detection mechanism 400 can also be located within the receiving space 105. Therefore, the length of the card tray 100 and the insertion detection mechanism can be shortened, thereby further shortening the overall length of the card connector. This further reduces the installation space occupied by the card connector in the electronic device, which is more conducive to the development of thinner and lighter electronic devices.

[0035] In the above embodiment, the card tray insertion detection mechanism 400 can be a photoelectric sensor. When the card tray is inserted into the card holder 200, the light from the photoelectric sensor is blocked, and the photoelectric sensor outputs a signal, thus indicating that the card tray 100 is inserted correctly. When the card tray 100 is not inserted correctly or is not inserted into the card holder 200, the light from the photoelectric sensor is not blocked, and the photoelectric sensor does not output a signal. Of course, the card tray insertion detection mechanism 400 can also be a contact switch, a pressure sensor, or other structures, which are not limited herein.

[0036] In another alternative embodiment, the card holder insertion detection mechanism 400 may include a detection contact 430 and a contact spring 420. The contact spring 420 may be fixedly connected to the card holder 200, and at least a portion of the contact spring 420 may be opposite to the detection contact 430. When the card holder 100 is inserted into the card holder 200, the detection contact 430 is opposite to the limiting beam 120, and the contact spring 420 is pushed by the limiting beam 120 to contact or separate from the detection contact 430.

[0037] In this scheme, when the detection contact 430 contacts the contact spring 420, the detection contact 430 and the contact spring 420 are electrically connected, thus forming a circuit. When the detection contact 430 separates from the contact spring 420, the circuit is broken. Therefore, by controlling the connection or disconnection of the detection contact 430 and the contact spring 420, a current signal is output or not output to determine whether the card tray 100 is inserted into the card holder 200. Thus, the card tray insertion detection mechanism 400 has a simple structure, low cost, and high reliability.

[0038] In another optional embodiment, the card tray insertion detection mechanism 400 further includes a detection unit 410, with a detection contact 430 disposed on the surface of the detection unit 410 facing the opening side of the card holder 200. Here, the opening side of the card holder 200 refers to the side used for inserting the card tray 100, which is the side where the first end 201 is located. The detection unit 410 includes, but is not limited to, structures such as circuit boards and electronic components. The detection unit 410 is used to output the detected signal to the main board of the electronic device. The fixed end of the contact spring 420 is connected to the card holder 200, and the free end of the contact spring 420 can be bent toward the detection contact 430 and opposite to the detection contact 430.

[0039] When the card tray 100 is outside the card holder 200, the contact spring 420 separates from the detection contact 430. At this time, the contact spring 420 is disconnected from the detection contact 430, and the detection unit 410 has no current signal input. Therefore, the detection unit 410 outputs a low-level signal, and at this time it is determined that the card tray 100 is not inserted into the card holder or the card tray 100 is not inserted into the preset position of the card holder 200.

[0040] When the card tray 100 is inserted into the card holder 200, the contact spring 420 is located within the receiving space 105. The limiting beam 120 presses down on the contact spring 420 so that the detection contact 430 comes into contact with the contact spring 420. At this time, the contact spring 420 and the detection contact 430 are connected, and the detection unit 410 receives a current signal input. Therefore, the detection unit 410 outputs a high-level signal. At this time, it is determined that the card tray 100 is inserted into the card holder 200 and inserted into a preset position.

[0041] The card tray insertion detection mechanism 400 described above can detect whether the card tray 100 is inserted into the card holder 200. However, in the card tray insertion detection mechanism 400 of the above structure, the card tray 100 presses against the contact spring 420 to make contact with the detection contact 430. When the installation accuracy of the card tray insertion detection mechanism 400 is low, the contact spring 420 may easily block the card tray 100 from being installed in the preset position of the card holder 200. Therefore, even if the card tray detection mechanism outputs a detection signal, the card tray 100 may still not be inserted in place. Therefore, the assembly accuracy of the card tray insertion detection mechanism 400 is relatively high.

[0042] In another alternative embodiment, the card holder insertion detection mechanism 400 further includes a detection section 410, and detection contacts 430 are disposed on the surface of the detection section 410 opposite to the opening side of the card holder 200. When the card tray 100 is outside the card holder 200, the contact spring 420 contacts the detection contact 430. At this time, the contact spring 420 and the detection contact 430 are connected, and the detection unit 410 receives a current signal input. Therefore, the detection unit 410 outputs a high-level signal, and it is determined that the card tray 100 is not inserted into the card holder 200 or is not inserted in place.

[0043] When the card tray 100 is inserted into the card holder 200, the contact spring 420 can be located within the receiving space 105. The limiting beam 120 presses down on the contact spring 420 to separate the detection contact 430 from the contact spring 420. At this time, the contact spring 420 is disconnected from the detection contact 430, and the detection unit 410 has no current signal input. Therefore, the detection unit 410 outputs a low-level signal. At this time, it is determined that the card tray 100 is inserted into the card holder 200 and inserted into the preset position.

[0044] In this design, when the card tray 100 is inserted, the detection contact 430 and the contact spring 420 can be separated. The deformation of the contact spring 420 is related to the insertion distance of the card tray 100, thus ensuring that the contact spring 420 and the detection contact 430 can be completely separated. This avoids the phenomenon where the detection unit 410 still has a current signal input due to incomplete separation of the contact spring 420 and the detection contact 430, thereby making the detection reliability of the card tray insertion detection mechanism 400 higher. In addition, the assembly precision of this type of card tray insertion detection mechanism 400 is low, making it less likely to obstruct the insertion of the card tray 100 into the card holder 200, thus reducing the manufacturing cost of the electronic device.

[0045] In another optional embodiment, the card holder 200 may include a mounting bracket 210, which serves as the mounting body of the card tray 100 and can also be understood as the housing of the card holder 200. Both the detection unit 410 and the contact spring 420 can be disposed on the mounting bracket 210. Optionally, the contact spring 420 can be fixed to the mounting bracket 210 by welding, snap-fitting, or riveting. However, fixing the contact spring 420 to the mounting bracket 210 by welding, riveting, or other methods requires other fixing components, resulting in a more complex structure and greater difficulty.

[0046] Therefore, in another alternative embodiment, the contact spring 420 can be an integral structural component with the mounting bracket 210. In this solution, the contact spring 420 and the mounting bracket 210 are integrally formed, so there is no need for other fixing structures to fix the contact spring 420 and the mounting bracket 210, thereby making the structure of the card connector simpler and the manufacturing process simpler.

[0047] Optionally, the contact spring 420 and the mounting bracket 210 can be manufactured using a one-piece stamping process, or the base of the contact spring 420 and the mounting bracket 210 can be first cut into shape using a laser machine, and then the base can be bent into shape using a bending machine. Of course, the contact spring 420 and the mounting bracket 210 can also be manufactured in other ways, which are not limited in this article.

[0048] To further reduce the size of the card connector, in another alternative embodiment, when the card tray 100 is inserted into the card holder 200, the rotating rod 320 and / or the rotating shaft 330 can both be located within the receiving space 105. In this arrangement, the rotating shaft 330 is completely located within the receiving space 105, thereby significantly shortening the overall length of the card tray 100 and the ejection mechanism 300. The length of the corresponding card holder 200 is also shortened, resulting in a shorter overall length of the card connector and further reducing its size.

[0049] Furthermore, a clearance opening 1221 can be formed on the side of the limiting beam 120 near the receiving space 105, and the clearance opening 1221 can communicate with the receiving space 105. When the card tray 100 is inserted into the card holder 200, the portion of the card tray insertion detection mechanism 400 can be located within the clearance opening 1221. This solution can further shorten the length of the card tray 100 and the card tray insertion detection mechanism 400, thus further shortening the overall length of the card connector, thereby further reducing the installation space occupied by the card connector in the electronic device, which is more conducive to the development of thinner and lighter electronic devices.

[0050] In another alternative embodiment, the limiting beam 120 may include a first beam segment 121 and a second beam segment 122 connected to each other, and the second beam segment 122 may have the aforementioned clearance opening 1221.

[0051] When the card holder 100 is inserted into the card slot 200, the first crossbeam section 121 abuts against the ejection mechanism 300. Specifically, the free end of the rotating rod 320 of the ejection mechanism 300 can abut against the first crossbeam section 121. The second crossbeam section 122 is disposed opposite to the card holder insertion detection mechanism 400, and at least a portion of the contact spring 420 of the card holder insertion detection mechanism 400 is located within the clearance opening 1221.

[0052] In this design, the ejector mechanism 300 needs to apply force to the first crossbeam segment 121. Therefore, the width of the first crossbeam segment 121 needs to be relatively large to ensure its strength. The second crossbeam segment 122 does not directly contact the ejector mechanism 300, so it requires less strength and can therefore have a smaller width. Since the width of the second crossbeam segment 122 can be smaller, the clearance opening 1221 can be created on it. This design ensures the strength of the limiting crossbeam 120 while shortening the length of the card connector, thus achieving a balance between increasing the strength of the limiting crossbeam 120 and reducing the length of the card connector.

[0053] Optionally, the elastic arm 1211 can be formed on the first crossbeam segment 121. In this case, the elastic arm 1211 can also help increase the strength of the first crossbeam segment 121, thereby further improving the strength of the first crossbeam segment 121.

[0054] To increase the deformation of the elastic arm 1211, in another optional embodiment, the tray 100 has a recessed groove 1212, which is formed by the limiting beam 120 and the elastic arm 1211. In this embodiment, the recessed groove 1212 provides a larger deformation space for the elastic arm 1211, thus allowing for a greater deformation of the elastic arm 1211.

[0055] Optionally, the clearance groove 1212 can be formed on the first crossbeam segment 121.

[0056] In another alternative embodiment, a retaining beam 111 may be provided on the edge of the insertion end 101 of the card tray 100. The retaining beam 111 and the limiting crossbeam 120 may be located on opposite sides of the card tray 100, respectively. In this embodiment, the retaining beam 111 is provided on the edge of the card tray 100 opposite to the receiving space 105. The retaining beam 111 can improve the strength of the edge of the card tray 100, thereby preventing the card tray 100 from bending during insertion and removal, thus improving the safety of the card tray 100.

[0057] Optionally, the card holder 100 may include a support plate 110, the edge of which near the insertion end 101 may be bent toward the side opposite to the receiving space 105, and the bent portion forms the aforementioned retaining beam 111. Of course, the retaining beam 111 may also be made in other ways, which are not limited herein.

[0058] In another alternative embodiment, the card holder 200 may include a mounting bracket 210 and a first limiting spring 220 disposed on the mounting bracket 210. The first limiting spring 220 may extend along the length direction of the card tray 100 and may be bent to form a first limiting portion 221. A first engaging portion 131 is disposed on the edge of the card tray 100. When the card tray 100 is inserted into the card holder 200, the first limiting portion 221 may abut against the first engaging portion 131 to limit the card tray 100.

[0059] In this design, after the card tray 100 is inserted into the card holder 200, the first limiting portion 221 of the first limiting spring 220 abuts against the first engaging portion 131, thereby fixing the card tray 100 within the card holder 200 to prevent it from accidentally falling out. This improves the safety and reliability of the assembly between the card tray 100 and the card holder 200. Furthermore, the first limiting portion 221 is a curved section formed on the first limiting spring 220, thus the structure of the first limiting spring 220 is simple and easy to manufacture.

[0060] In the above embodiments, the first limiting part 221 can be located in the middle of the first limiting spring 220, and both ends of the first limiting spring 220 can be fixed on the mounting bracket 210. Since the first limiting spring 220 is fixed at both ends, the first limiting spring 220 has greater strength and is more difficult to deform, which makes the installation of the card holder 100 and the card seat 200 more difficult.

[0061] In another optional embodiment, one end of the first limiting spring 220 is fixed to the mounting bracket 210, and the free end of the first limiting spring 220 can be bent outward toward the card holder 200 to form a first limiting portion 221. The first limiting portion 221 is the bent section of the first limiting spring 220, and the first engaging portion 131 is a recess formed on the card holder 100. In this solution, one end of the first limiting spring 220 is a fixed end, used to connect with the mounting bracket 210 to fix the first limiting spring 220. The other end of the first limiting spring 220 is a free end. The free end of the first limiting spring 220 is bent to form the first limiting portion 221.

[0062] Since the free end of the first limiting spring 220 does not need to be fixed and is bent toward the recess on the card tray as the first snap-fit ​​portion 131, the position of the mounting bracket 210 near the free end of the first limiting spring 220 can be recessed inward, thereby reducing the width dimension of the mounting bracket 210, which in turn can further reduce the width dimension of the card connector.

[0063] Furthermore, the first limiting spring 220 is integrally formed with the mounting bracket 210. Therefore, the fixed end of the first limiting spring 220 can serve as a side plate of the card holder 200 to limit the card tray and guide its movement. Thus, the free end of the first limiting spring 220 can also replace the existing structure used to limit the card tray in the card holder, thereby reducing the width of the card connector by significantly reducing the width of the card holder 200.

[0064] Furthermore, since the first limiting spring 220 is fixed on one side, and the first limiting part 221 is far from the fixed end of the first limiting spring 220, the first limiting spring 220 has a larger torque and is more prone to deformation, thus making it easier to insert the card holder 100 into the card slot 200. In addition, the single-sided fixing method of the first limiting spring 220 is more convenient to manufacture and assemble than the double-sided fixing method. The single-sided fixing method also reduces the likelihood of interference with other components, improving the reliability of its assembly.

[0065] Furthermore, a recess is formed on the card tray 100. Therefore, when the card tray 100 is inserted into the card holder 200, the first limiting part 221 is located in the recess. At this time, compared with the structure of the first card receiving part 131 being a protrusion, the method of fixing the first limiting part 221 with a recess can make the width of the card tray 100 and the card holder 200 smaller, thus further shortening the width of the card connector.

[0066] Furthermore, the mounting bracket 210 and the first limiting spring 220 are integrally formed. Specifically, the mounting bracket 210 and the first limiting spring 220 can be stamped together, or the mounting bracket 210 and the first limiting spring 220 can be contoured by a laser machine and then bent by a bending machine. Of course, the mounting bracket 210 and the first limiting spring 220 can also be manufactured using other integral forming processes, which are not limited here. Since the mounting bracket 210 and the first limiting spring are integrally formed, the fixing structure used to fix the mounting bracket 210 and the first limiting spring 220 can be eliminated, thus allowing the connection position of the first limiting spring 220 and the mounting bracket 210 to be further recessed inward, thereby further shortening the width of the card holder 200.

[0067] In another optional embodiment, the card holder 200 may further include a second limiting spring 230 disposed on the mounting bracket 210. The second limiting spring 230 may extend along the length direction of the card tray 100. The second limiting spring 230 and the first limiting spring 220 may be disposed on opposite sides of the mounting bracket 210. The second limiting spring 230 may be bent to form a second limiting portion 231. A second engaging portion 132 is correspondingly disposed on the edge of the card tray 100. When the card tray 100 is inserted into the card holder 200, the second limiting portion 231 may abut against the second engaging portion 132 to limit the card tray 100. In this solution, limiting springs are provided on opposite sides of the card holder 200, thereby increasing the fastening force of the card holder 200 on the card tray 100, and further improving the assembly reliability of the card tray 100 and the card holder 200.

[0068] In the above embodiments, when the first limiting spring 220 and the second limiting spring 230 are at the same height, the two latching parts on the card holder 100 are also at the same height. The dimensions of the two latching parts are added together in the width direction of the card holder 100, thus making the width of the card holder 100 larger.

[0069] Based on this, in another optional embodiment, the first limiting part 221 and the second limiting part 231 can be offset along the length direction of the card holder 100. In this case, the latching parts on both sides of the card holder 100 are offset, thereby reducing the width of the card holder 100 and the card base 200.

[0070] Furthermore, as mentioned above, the point at which the lever 320 applies force to the clip 100 will not be at the center of the clip 100; rather, the point at which the lever 320 applies force to the clip 100 is generally located towards the first limiting spring 220 or the second limiting spring 230. For example... Figure 2As shown, the first limiting part 221 and the second limiting part 231 are offset. At this time, the contact point between the rotating rod 320 and the card holder 100, the first limiting part 221 and the second limiting part 231 can form a stable triangular structure, thereby preventing the card holder 100 from shifting and rotating when it is pushed out, and thus preventing it from getting stuck in the card holder 200. Specifically, the distance between the first limiting parts 221 is the first distance, the distance between the contact point between the rotating rod 320 and the card holder 100 and the second limiting part 231 can be the second distance, and the distance between the first limiting part 221 and the second limiting part 231 is the third distance. Since the distance between the first limiting part 221 and the contact point between the rotating rod 320 and the card holder 100 is relatively close, the first distance is less than the second distance, and the second distance is less than the third distance.

[0071] In the above embodiments, the structure of the second limiting spring 230 can be the same as that of the first limiting spring 220, and this document does not impose any restrictions.

[0072] In another alternative embodiment, the card tray 100 is further provided with a second card slot 104. The second card slot 104 and the first card slot 103 can be distributed along the thickness direction of the card tray 100. The orientation of the first card slot 103 is opposite to that of the second card slot 104. The receiving space 105 and the first card slot 103 are located on the same side of the card tray 100.

[0073] In this design, card slots are provided on both opposite sides of the card tray 100. Cards in the first card slot 103 and cards in the second card slot 104 can be stacked. This design utilizes the thickness direction of the card tray 100 to stack multiple cards. Therefore, this design can both reduce the size of the card tray 100 and increase the number of card mounting positions.

[0074] Furthermore, the card tray 100 may also have a second card slot 104. The length direction of the second card slot 104 is perpendicular to the length direction of the first card slot 103, and the length direction of the second card slot 104 may be parallel to the length direction of the card tray 100. Since the receiving space 105 and the first card slot 103 are located on the same side, the first card slot 103 is arranged laterally to reserve space for opening, while the receiving space 105 has no impact on the side where the second card slot 104 is located. Therefore, the cards in the second card slot 104 are arranged vertically, so the second card slot 104 can be used to install larger cards, further optimizing the layout of the card connector.

[0075] In the above embodiments, the card holder 100 includes a support plate 110, a first limiting beam 141, a second limiting beam 142, a third limiting beam, and a fourth limiting beam 144, which together form a first card slot 103. The card holder 100 may also include a fifth limiting beam 151, a sixth limiting beam 152, a seventh limiting beam 153, and an eighth limiting beam 154, which can be sequentially connected end-to-end. These beams, along with the support plate 110, can form a second card slot 104. The fifth limiting beam 151 and the seventh limiting beam 153 are arranged along the length of the card holder 100. The seventh limiting beam 153 can be located at the insertion end 101 and is set at the edge of the support plate 110. The sixth limiting beam 152 and the eighth limiting beam 154 are arranged opposite each other and distributed along the width of the card holder 100. When the card holder 100 has a second card slot 104, the aforementioned stop beam 111 is the seventh limiting beam here.

[0076] Since there is no need to open a receiving space 105 on the side where the second card slot 104 of the card holder 100 is located, the seventh limiting beam 153 used to form the second card slot 104 can be set at the edge of the support plate 110, so that the second card slot 104 has a larger volume.

[0077] In the above embodiment, the receiving space 105 can be used to avoid the ejection mechanism 300. When the card tray 100 is located within the card holder 200, a portion of the ejection mechanism 300 can be located within the receiving space 105. When the card is ejected, the ejection mechanism 300 can apply force to the aforementioned third limiting beam. Therefore, the third limiting beam needs to have a certain width to meet its rigidity requirements. The seventh limiting beam 153 is not subjected to force and is only used to limit the card. Therefore, the width of the seventh limiting beam 153 can be set to be relatively small. Preferably, the support plate 110 can be bent towards the side of the second card slot 104 to form the seventh limiting beam 153. Of course, the seventh limiting beam 153 can also have other structures, which are not limited herein.
