Abstract
Description
Technical Field
[0001] The embodiments of the present application relate to the technical field of electronic devices, and in particular to a card holder and an electronic device. Background Art
[0002] With the development of electronic devices, various data cards (such as communication cards, memory cards, etc.) need to be installed in electronic devices to meet the needs of their various functions. Taking mobile phones as an example, a Subscriber Identification Module (SIM card) is usually required in mobile phones to realize communication functions. The SIM card needs to be electrically connected to the mobile phone motherboard through the corresponding card socket.
[0003] However, the existing card holders are prone to breakage, deformation and other problems during the production process, resulting in an increased card holder scrap rate. Utility Model Content
[0004] The embodiments of the present application provide a card holder and an electronic device, which are used to solve the problem that the existing card holder is prone to breakage or deformation during production and use.
[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:
[0006] In a first aspect, an embodiment of the present application provides a card holder, which is applied to an electronic device. The electronic device includes a shell and a mainboard. The mainboard is arranged in the shell. The card holder includes a plurality of spring pieces.
[0007] Among them, a plurality of spring sheets are respectively fixed on the main board, and the plurality of spring sheets are arranged in an array, and two adjacent spring sheets are arranged at intervals. The spring sheets are used for electrical connection between the data card of the electronic device and the main board.
[0008] The card holder provided in the first aspect of the present application is provided by fixing a plurality of spring pieces on the main board independently. When one of the spring pieces fails (e.g., deformed, broken, poorly contacted, rusted, etc.), only the faulty spring piece needs to be replaced. In other words, each spring piece in the card holder provided by the present application can be replaced individually as a completely independent component. Individual faulty spring pieces will not cause the entire card holder to be scrapped, thereby effectively reducing the scrap rate and production cost of the card holder. In addition, the number of spring pieces in the card holder provided by the present application and the arrangement on the main board can be arbitrarily combined and arranged according to demand, so it is more versatile and can effectively reduce the development cycle and development cost of the card holder.
[0009] In combination with the first aspect, in a possible implementation, the spring sheet includes an elastic arm and a bottom plate, the bottom plate is fixed to the main board, the elastic arm is arranged on the bottom plate, and the elastic arm is used to abut against the data card. Since the elastic arm is generally small, it is not convenient to directly weld it with the main board. Even after direct welding, the welding position of the elastic arm and the main board is prone to desoldering during the repeated deformation of the elastic arm. Therefore, the elastic arm can be arranged on the main board, for example, the elastic arm and the bottom plate are integrally stamped and formed, and then the bottom plate is welded to the main board, so as to facilitate the fixation of the spring sheet.
[0010] In combination with the first aspect, in another possible implementation, the elastic arm has a fixed end, a contact portion and a movable end which are distributed in sequence, the fixed end is fixedly connected to the bottom plate, the contact portion extends to a side away from the bottom plate, and the bottom plate is located between the contact portion and the main board, and the movable end can move relative to the bottom plate. In this way, when the data card of the electronic device is inserted into the card holder, the elastic arm will be elastically deformed under the pressure of the data card, the movable end will move relative to the bottom plate, and the spacing between the contact portion and the bottom plate will gradually decrease. After the data card is inserted into place, the contact portion will always remain in contact with the metal contact sheet on the data card, thereby ensuring the stability of the electrical connection between the data card and the main board.
[0011] In combination with the first aspect, in another possible implementation, the elastic arm includes a first arm and a second arm, the first end of the first arm is a fixed end and is fixedly connected to the bottom plate; the first arm extends in a direction away from the bottom plate and the main board; the second end of the first arm is fixedly connected to the first end of the second arm, the connection between the first arm and the second arm forms a contact portion, and the second end of the second arm is a movable end. In this way, the above structural design facilitates the integrated stamping of the bottom plate and the elastic arm of the spring sheet, thereby simplifying the production process of the spring sheet, improving production efficiency, and reducing production costs.
[0012] In combination with the first aspect, in another possible implementation, an opening is provided on the base plate, the opening passes through the base plate along the thickness direction of the base plate, the first end of the first arm is fixed to the inner wall of the opening, and the vertical projection of the elastic arm on the plane where the base plate is located is located in the opening.
[0013] In combination with the first aspect, in another possible implementation, the spring piece further includes a limiting portion, the limiting portion is disposed on the bottom plate, the limiting portion and the bottom plate are spaced apart, and the movable end extends between the limiting portion and the bottom plate. In this way, through the above structural design, it is equivalent to forming a limiting groove between the limiting portion and the bottom plate, and the movable end of the elastic arm extends into the limiting groove, that is, the limiting portion is used to completely separate the movable end of the elastic arm from the data card and the main board, thereby preventing the movable end of the elastic arm from scratching the data card and the main board when moving relative to the bottom plate.
[0014] In combination with the first aspect, in another possible implementation, the movable end of the elastic arm is provided with a first extension portion and a second extension portion, and the first extension portion and the second extension portion are respectively provided on both sides of the movable end of the elastic arm in a direction parallel to the bottom plate. The limiting portion includes a first limiting portion and a second limiting portion, the first extension portion extends between the first limiting portion and the bottom plate, and the second extension portion extends between the second limiting portion and the bottom plate. In this way, through the above structural design, it is equivalent to forming a first limiting groove between the first limiting portion and the bottom plate, and forming a second limiting groove between the second limiting portion and the bottom plate, and the first extension portion and the second extension portion extend into the first limiting groove and the second limiting groove respectively, that is, the first limiting portion is used to separate the first extension portion of the movable end from the data card and the main board, and the second limiting portion is used to separate the second extension portion of the movable end from the data card and the main board, so as to prevent the movable end of the elastic arm from driving the first extension portion and the second extension portion to scratch the main board and the data card when moving relative to the bottom plate.
[0015] In combination with the first aspect, in another possible implementation, the bottom plate, the elastic arm and the limiter are integrally formed. For example, the bottom plate, the spring sheet and the limiter can be directly formed on a metal plate by stamping or bending, which has a higher utilization rate of raw materials and is conducive to reducing production costs.
[0016] In combination with the first aspect, in another possible implementation, the spring sheet further includes an insulator, which is disposed on the bottom plate, covers at least a portion of the edge of the bottom plate, and faces another adjacent spring sheet. Since the bottom plate and the elastic arm are generally made of metal, by disposing an insulator at the edge of the bottom plate, it is possible to avoid direct contact between the bottom plates of the two spring sheets when the two spring sheets are disposed close to each other, thereby preventing the data card from short-circuiting. The insulator may be an insulating paint sprayed on the bottom plate, an insulating film attached to the bottom plate, or an insulating plastic layer injection-molded on the bottom plate.
[0017] In combination with the first aspect, in another possible implementation, the card holder includes six springs, wherein the six springs are arranged in a rectangular array of two rows and three columns. An existing SIM card generally has six pins, and the six pins are VCC (power), RST (reset), CLK (clock), I / O (data), GND (ground) and VPP (programming). Thus, the six springs are respectively connected to the six pins of the SIM card to ensure the normal use of various functions of the SIM card.
[0018] In a second aspect, the present application provides an electronic device, which includes a housing, a mainboard, a card tray, and the card holder of the first aspect, wherein the card holder is electrically connected to the mainboard, the card tray is used to carry a data card, the card tray is inserted into the housing, and the data card abuts against a spring sheet of the card holder.
[0019] In combination with the second aspect, in a possible implementation, the shell includes a frame and a battery cover, the battery cover is fixedly connected to the frame, the frame is provided with a mounting hole, and the card holder is inserted into the mounting hole.
[0020] It can be understood that the beneficial effects that can be achieved by the electronic device described in the second aspect and any possible implementation thereof provided above can refer to the beneficial effects in the first aspect and any possible implementation thereof, and will not be repeated here.

[0037] In order to make the purpose, technical solution and advantages of the application more clear, the present application is further described in detail below in conjunction with the embodiments. 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.

The "quantity" mentioned above cannot be understood as limiting the present application.
[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0040] The embodiment of the present application provides an electronic device 01. Specifically, the electronic device 01 may be a portable electronic device or other types of electronic devices. For example, the electronic device may be a mobile phone, a tablet personal computer, a personal digital assistant (PDA), a monitor, a wearable device, etc. For the convenience of explanation, the following examples are all taken as an example of the electronic device 01 being a mobile phone.
[0041] See also Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the overall structure of the electronic device 01 provided in the embodiment of the present application. Figure 2 For the above Figure 1 Exploded diagram of the structure of the electronic device 01. As can be seen from the above, in this embodiment, the electronic device 01 is a mobile phone, and the electronic device 01 can be in an approximately rectangular plate-shaped structure. The electronic device 01 can include a display module 10, a housing 20, a camera module 30, a mainboard 40, a camera decorative cover 50, a battery 60, a card tray 70, a card holder 80, and a data card 90.
[0042] The data card 90 may be a NM card (Nano Memory Card), an SD card (Secure Digital Card), a TF card (TransFlash), a SIM card (Subscriber Identity Module), etc., and this application does not specifically limit this. For the sake of convenience, the following examples are all taken as an example in which the data card 90 is a SIM card.
[0043] For the convenience of the following description, an XYZ coordinate system is established, and the width direction of the electronic device 01 is defined as the X-axis direction, the length direction of the electronic device 01 is defined as the Y-axis direction, and the thickness direction of the electronic device 01 is defined as the Z-axis direction. Therefore, this application does not make any special restrictions on this. It can be understood that Figure 1 and Figure 2 Only some components of the electronic device 10 are schematically shown, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and Figure 2 restrictions.
[0044] The above-mentioned display module 10 is used to display images, videos, etc. The display module 10 may include a light-transmitting cover plate 11 and a display screen 12 (English name: panel, also called display panel), and the light-transmitting cover plate 11 and the display screen 12 are stacked. The material of the light-transmitting cover plate 11 includes but is not limited to glass. For example, the light-transmitting cover plate 11 can adopt an ordinary light-transmitting cover plate to protect the display screen to avoid damage to the display screen due to external force, and it can play a dust-proof role. Alternatively, the light-transmitting cover plate 11 can also adopt a light-transmitting cover plate with a touch function, so that the electronic device 01 has a touch function, which makes it more convenient for users to use. Therefore, the present application does not specifically limit the specific material of the light-transmitting cover plate 11.
[0045] In addition, the display screen 12 may be a flexible display screen or a rigid display screen. For example, the display screen 12 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-E) display screen, a micro light-emitting diode (MIL-E) display screen, a microorganic light-emitting diode (MIL-E) display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).
[0046] The housing 20 is used to protect the electronic components inside the electronic device 01. The housing 20 may include a battery cover 21 and a frame 22. The battery cover 21 is located on the side of the display screen 12 away from the light-transmitting cover plate 11, and is stacked with the light-transmitting cover plate 11 and the display screen 12. The frame 22 is located between the light-transmitting cover plate 11 and the battery cover 21. The battery cover 21 is fixed to the frame 22. For example, the battery cover 21 may be fixed to the frame 22 by bonding, threading, welding, snapping, etc. The light-transmitting cover plate 11 may be fixed to the frame 22 by gluing, so that the light-transmitting cover plate 11, the battery cover 21, and the frame 22 form a receiving cavity inside the electronic device 01. The display screen 12, the main board 40, and the camera module 30 are all arranged in the internal receiving space.
[0047] In some embodiments, the housing 20 may further include a middle plate 23, which is disposed in the accommodating cavity and is located on the side of the display screen 12 away from the light-transmitting cover plate 11. The middle plate 23 is fixedly connected to the frame 22 to form the middle frame of the electronic device 10. For example, the middle plate 23 and the frame 22 may be fixedly connected by gluing, threading, welding, snapping, etc.; or, the middle plate 23 and the frame 22 may also be an integrally formed structure, that is, the middle plate 23 and the frame 22 form a structural component as a whole. The middle plate 23 divides the accommodating cavity into two independent spaces, one of which is located between the light-transmitting cover plate 11 and the middle plate 23, and the display screen 12 is located in the space. The other space is located between the middle plate 23 and the battery cover 21, and the main board 40, the camera module 30 and the battery 60 are all arranged in the space.
[0048] The camera module 30 is used to realize video or image shooting and can realize auto focus (AF, AutoFocus), so it can be applied to various shooting scenes. Figure 1 As shown, the camera module 30 is arranged near a side edge of the rear cover 21. Alternatively, the camera module 30 may be located at a middle position of the upper portion of the rear cover 21 (not shown in the figure). Therefore, the specific position of the camera module 30 is not particularly limited in this application.
[0049] Specifically, the camera module 30 has a light incident surface and a light emitting surface. The light incident surface may be the light incident surface of the lens inside the camera module 30, and the light emitting surface may be the light emitting surface of the lens inside the camera module 30. The light incident surface of the camera module 30 faces the back plate 21, and the external light enters the camera module 30 from the light incident surface of the camera module 30. The camera module 30 converts the received light signal into a digital signal, outputs it to a digital signal processor (DSP, Digital Signal Processing) for image signal enhancement and compression optimization, and finally transmits it to the Figure 2 An image is displayed on the display screen 12 shown.
[0050] The camera decorative cover 50 is used to prevent foreign objects such as dust from outside from entering the electronic device 01 or the camera module 30, and to prevent the camera module 30 from being scratched or hit by external objects.
[0051] The mainboard 40 is used to set the electronic components of the electronic device 10 and realize the electrical connection between the electronic components. The battery 60 is electrically connected to the mainboard 40 to provide power to the electronic components. Exemplarily, the electronic components can be a control chip (such as a system on chip, System on Chip, SOC), a graphics control chip (graphics processing unit, GPU), a universal flash storage (UFS), an earpiece, a flash module, and the camera module 30, etc.
[0052] The data card 90 (SIM card) is used to realize the communication function of the electronic device 01. The card holder 80 is used to realize the electrical connection between the data card 90 (SIM card) and the mainboard 40. Figure 2 As shown, the card holder 80 is welded on the main board 40, and a mounting hole 220 is provided on the frame 22 at a position opposite to the card holder 80. After the data card 90 (SIM card) is installed on the card tray 70, it is inserted into the electronic device 01 through the mounting hole 220 together with the card tray 70. After insertion, the various pins (commonly known as gold fingers) on the data card 90 (SIM card) will abut against the corresponding elastic contact pieces 82 on the card holder 80, thereby completing the electrical connection with the main board 40.
[0053] It should be noted that the length direction of the above-mentioned card holder 80 can be parallel to the length direction (i.e., the Y-axis direction) of the above-mentioned electronic device 01, and the width direction of the card holder 80 can be parallel to the width direction (i.e., the X-axis direction) of the electronic device 01. Alternatively, the length direction of the above-mentioned card holder 80 can be parallel to the width direction (i.e., the X-axis direction) of the above-mentioned electronic device 01, and the width direction of the card holder 80 can be parallel to the length direction (i.e., the Y-axis direction) of the electronic device 01. It can be understood that the arrangement of the above-mentioned card holder 80 is only an example, that is, the card holder 80 can also be arranged on the mainboard 40 of the electronic device 01 in other ways.
[0054] See also Figure 3 As shown, Figure 3 The overall structure diagram of a card holder 80 provided in an embodiment of the present application is shown. Specifically, the card holder 80 includes a metal sheet 83 and a plurality of arched elastic contact pieces 82, and the plurality of elastic contact pieces 82 are arranged in an array on one side of the metal sheet 83. The elastic contact piece 82 extends along the length direction of the card holder 80, and one end of the elastic contact piece 82 is connected to the metal sheet 83. The card holder 80 is welded to the main board 40 through the welding point on the metal sheet 83.
[0055] Among them, since multiple elastic contact pieces 82 are arranged on the same metal sheet 83, that is, multiple elastic contact pieces 82 are electrically connected to the mainboard through the same metal sheet 83, when one of the elastic contact pieces 82 has a problem (such as breakage, deformation, rust, etc.), the entire card holder 80 will be scrapped, which will lead to an increase in the scrap rate and an increase in production costs.
[0056] To solve the above problems, the present application provides another card holder 80, see Figure 4 As shown, Figure 4 This is a schematic diagram of another card holder 80 provided in an embodiment of the present application being arranged on a mainboard 40.
[0057] The card holder 80 includes a plurality of spring pieces 81. The plurality of spring pieces 81 are respectively fixed on the main board, and the plurality of spring pieces 81 are arranged in an array, and two adjacent spring pieces 81 are arranged at intervals.
[0058] In this way, by independently fixing the plurality of spring pieces 81 on the main board, when a certain spring piece 81 fails (e.g., deformed, broken, poorly contacted, rusted, etc.), only the corresponding failed spring piece 81 needs to be replaced. In other words, each spring piece 81 in the above-mentioned card holder 80 can be replaced individually as a completely independent component, and a single failed spring piece 81 will not cause the entire card holder 80 to be scrapped, thereby effectively reducing the scrap rate and production cost of the card holder 80.
[0059] In addition, the number of spring pieces 81 in the above-mentioned card holder 80 and their arrangement on the mainboard can be arbitrarily combined and arranged according to needs, so it is more versatile and can effectively reduce the research and development cycle and research and development cost of the card holder 80.
[0060] It is understandable that each of the above-mentioned spring pieces 81 can be electrically connected to the mainboard by welding, riveting, threaded connection, conductive adhesive bonding, etc., and the present application does not make any special limitation on this.
[0061] The arrangement of the multiple springs 81 can be a rectangular array, a circular array or other array forms, so as to satisfy the one-to-one connection with each pin of the data card 90, and the present application does not make any special limitation on this.
[0062] For example, the data card 90 is a SIM card.
[0063] In some embodiments, a SIM card generally has six pins, see Figure 5 As shown, Figure 5The figure is a pin diagram of a SIM card. The six pins are VCC (power), RST (reset), CLK (clock), I / O (data), GND (ground) and VPP (programming). Correspondingly, the card holder 80 also has six springs 81, which are respectively connected to the six pins of the SIM card, thereby ensuring the normal use of various functions of the SIM card.
[0064] For example, see Figure 4 As shown. The card holder 80 includes six spring pieces 81, and the six spring pieces 81 are respectively a first spring piece 81a, a second spring piece 81b, a third spring piece 81c, a fourth spring piece 81d, a fifth spring piece 81e, and a sixth spring piece 81f. The six connecting members are arranged in a rectangular array of two rows and three columns, and are arranged in two rows in the length direction (Y-axis direction) of the electronic device 01, and are arranged in three columns in the width direction (X-axis direction) of the electronic device 01. In the illustrated orientation, the first row from left to right is the first spring piece 81a, the second spring piece 81b, and the third spring piece 81c, and the second row from left to right is the fourth spring piece 81d, the fifth spring piece 81e, and the sixth spring piece 81f.
[0065] Among them, see Figure 6 As shown, Figure 6 for Figure 4 The deck 80 and Figure 5 Schematic diagram of the connection between the pins of the SIM card. The first spring 81a and the VCC pin of the SIM card ( Figure 6 The dotted line area A) corresponds to the second spring piece 81b and the RST pin ( Figure 6 The third spring piece 81c contacts the CLK pin of the SIM card ( Figure 6 The fourth spring piece 81d abuts against the GND pin ( Figure 6 The dotted line area D) corresponds to the abutment, and the fifth spring piece 81e abuts against the I / O pin ( Figure 6 The dotted line area E) corresponds to the abutment, and the sixth spring piece 81f abuts against the VPP pin ( Figure 6 The middle dotted area F) corresponds to the abutment.
[0066] Assuming that the first spring piece 81a is deformed and causes poor contact of the SIM card, at this time, it is only necessary to remove the first spring piece 81a from the mainboard and replace it with a new spring piece 81, without the need to simultaneously replace the other five spring pieces 81 of the card holder 80.
[0067] With the development of technology, SIM cards with eight pins have begun to be put into use. The eight pins of the SIM card are VCC (power), RST (reset), CLK (clock), I / O (data), GND (ground), VPP (programming) and two RFUs (Reserved for Future Use). Since two of the RFUs are not used, the card holder 80 with six springs 81 in the above embodiment can also be used for SIM cards with eight pins. The specific distribution method and corresponding relationship can be referred to the above embodiment, which will not be repeated here.
[0068] In some other embodiments, another card holder 80 is provided, which has eight spring pieces 81, which is equivalent to adding a seventh spring piece and an eighth spring piece to the card holder 80 having six spring pieces 81 in the above embodiment. Figure 6 The seventh spring clip and the eighth spring clip respectively correspond to the two RFU pins connected to the SIM card.
[0069] Based on this, the card holder 80 provided in the embodiment of the present application, by independently fixing multiple springs 81 on the main board 40, each spring 81 can be replaced individually as a completely independent component, and the failure of individual springs 81 will not cause the entire card holder 80 to be scrapped, thereby effectively reducing the scrap rate and production cost of the card holder 80. Moreover, the number of springs 81 in the card holder 80 and the arrangement method on the main board 40 can be arbitrarily combined and arranged according to needs, so it is more versatile and can effectively reduce the research and development cycle and research and development cost of the card holder 80.
[0070] It should be noted that the length direction of the spring sheet 81 may be parallel to the length direction (i.e., the Y-axis direction) of the holder 80, and the width direction of the spring sheet 81 may be parallel to the width direction (i.e., the X-axis direction) of the holder 80. Alternatively, the length direction of the spring sheet 81 may be parallel to the width direction (i.e., the X-axis direction) of the holder 80, and the width direction of the spring sheet 81 may be parallel to the length direction (i.e., the Y-axis direction) of the holder 80. It is understood that the arrangement of the spring sheet 81 is only an example, that is, the spring sheet 81 may also be arranged in the holder 80 in other ways.
[0071] In some embodiments, see Figure 7 As shown, Figure 7 The schematic diagram of the structure of a spring piece 81 provided in an embodiment of the present application is as follows. The spring piece 81 may include an elastic arm 811 and a bottom plate 812 , the bottom plate 812 is fixed to the mainboard, the elastic arm 811 is arranged on the bottom plate 812 , and the elastic arm 811 is used to abut against the pin of the data card 90 .
[0072] The elastic arm 811 has a fixed end 811a, a contact portion 811b and a movable end 811c which are sequentially arranged. The fixed end 811a is fixedly connected to the bottom plate 812, the contact portion 811b extends to a side away from the bottom plate 812, the contact portion 811b is used to abut against the pin of the data card 90, and the movable end 811c can move relative to the bottom plate 812.
[0073] In this way, the bottom plate 812 can be welded to the main board 40 to achieve the overall fixation of the spring piece 81. In addition, when the data card 90 of the electronic device 01 is inserted into the card holder 80, the elastic arm 811 will be elastically deformed under the pressure of the data card 90, and the movable end 811c will move relative to the bottom plate 812, and the distance between the contact portion 811b and the bottom plate 812 will gradually decrease. After the data card 90 is inserted into place, the contact portion 811b will always be in contact with the pin of the data card 90, thereby ensuring the stability of the electrical connection between the data card 90 and the main board 40.
[0074] It is understandable that the elastic arm 811 and the bottom plate 812 can be connected by welding, bonding, clamping, etc. Alternatively, the elastic arm 811 and the bottom plate 812 can also be connected to form an integral structure, that is, the elastic arm 811 and the bottom plate 812 form a structural component as a whole, and there is no separation fault between the two. Compared with the split structure, the integral structure is more solid and easy to manufacture (for example, one-time molding by stamping, casting, 3D printing, etc.).
[0075] For example, see Figure 7 As shown. The spring piece 81 is formed by one-time stamping. The bottom plate 812 is a rectangular ring structure, and the elastic arm 811 is V-shaped. At this time, the bottom plate 812 includes a first wall plate 8121 and a second wall plate 8122 parallel to the XZ plane, and a third wall plate 8123 and a fourth wall plate 8124 parallel to the YZ plane. The first wall plate 8121, the third wall plate 8123, the second wall plate 8122 and the fourth wall plate 8124 are connected end to end in sequence to form a rectangular opening 820 in the middle area of the bottom plate 812.
[0076] The elastic arm 811 is fixed on the inner wall of the opening 820 and extends from the first wall plate 8121 to the second wall plate 8122. In addition, since the spring piece 81 is formed by one-time stamping, the vertical projection of the elastic arm 811 on the plane where the bottom plate 812 is located is located in the opening 820.
[0077] The elastic arm 811 includes a first arm 8111 and a second arm 8112. The first end of the first arm 8111 is a fixed end 811a, and is fixedly connected to the first wall plate 8121. The first arm 8111 extends in a direction away from the bottom plate 812, and the second end of the first arm 8111 is fixedly connected to the first end of the second arm 8112, and the angle between the first arm 8111 and the second arm 8112 is an obtuse angle. A contact portion 811b is formed at the connection between the first arm 8111 and the second arm 8112, and in order to prevent the contact portion 811b from scratching the data card 90, a circular arc transition treatment is also performed at the connection between the first arm 8111 and the second arm 8112. The second end of the second arm 8112 is a movable end 811c.
[0078] When data card 90 is inserted, see Figure 8 As shown, Figure 8 for Figure 7 Side view of the middle spring piece 81 (along the X-axis direction). The contact portion 811b of the elastic arm 811 gradually approaches the bottom plate 812, and the movable end 811c of the elastic arm 811 slides toward the second wall plate 8122 along the length direction of the bottom plate 812 (Y-axis direction). During this process, the angle α between the first arm 8111 and the second arm 8112 gradually increases.
[0079] For another example, see Fig. 9 As shown, Fig. 9 A schematic diagram of another spring 81 provided in an embodiment of the present application: The bottom plate 812 is a rectangular plate structure having a first edge 812a and a second edge 812b opposite to each other, and the elastic arm 811 is V-shaped and extends from the first edge 812a to the second edge 812b.
[0080] The elastic arm 811 includes a first arm 8111 and a second arm 8112. The first arm 8111 extends in a direction away from the bottom plate 812. The first end of the first arm 8111 is a fixed end 811a and is fixedly connected to the first edge 812a of the bottom plate 812. The second end of the first arm 8111 is fixedly connected to the first end of the second arm 8112, and the angle between the first arm 8111 and the second arm 8112 is an acute angle. A contact portion 811b is formed at the connection between the first arm 8111 and the second arm 8112, and in order to prevent the contact portion 811b from scratching the data card 90, a circular arc transition treatment is also performed at the connection between the first arm 8111 and the second arm 8112. The second end of the second arm 8112 is a movable end 811c.
[0081] When data card 90 is inserted, see Fig.10 As shown, Fig.10 for Fig. 9Side view of the middle spring piece 81 (along the X-axis direction). The contact portion 811b of the elastic arm 811 will gradually approach the bottom plate 812, and the movable end 811c of the elastic arm 811 will slide along the bottom plate 812 toward the fixed end 811a (i.e., gradually approach the first edge 812a of the bottom plate 812). During this process, the angle β between the first arm 8113 and the second arm 8114 gradually decreases, and the angle γ between the first arm 8111 and the bottom plate 812 also gradually decreases.
[0082] On the basis of the above, see Fig.11 As shown, Fig.11 A schematic diagram of the structure of another spring piece 81 provided in an embodiment of the present application. The spring piece 81 may further include a limiting portion 813. The limiting portion 813 is disposed on the bottom plate 812, and the limiting portion 813 and the bottom plate 812 are spaced apart, and the movable end 811c of the elastic arm 811 extends between the limiting portion 813 and the bottom plate 812.
[0083] From another perspective, it is equivalent to forming a limiting groove 810 between the limiting portion 813 and the bottom plate 812, and the movable end 811c of the elastic arm 811 extends into the limiting groove 810. In other words, the movable end 811c of the elastic arm 811 is completely separated from the data card 90 and the main board 40 by the limiting portion 813, so as to prevent the movable end 811c of the elastic arm 811 from scratching the data card 90 and the main board 40 when moving relative to the bottom plate 812.
[0084] For example, see Fig.11 As shown, Fig.11 The shrapnel 81 in the above Figure 7 A limiting portion 813 is additionally provided on the basis of the middle spring piece 81. The limiting portion 813 is provided on the second wall plate 8122, and the limiting portion 813 and the second wall plate 8122 are spaced apart, so that a limiting groove 810 is formed between the limiting portion 813 and the second wall plate 8122, and the movable end 811c of the elastic arm 811 (i.e., the second end of the second arm 8112) extends into the limiting groove 810, and then the movable end 811c of the elastic arm 811 is completely separated from the data card 90 and the main board 40 by the limiting portion 813, so as to prevent the data card 90 and the main board 40 from being scratched.
[0085] For another example, see Fig.12 As shown, Fig.12 A schematic diagram of the structure of another spring piece 81 provided in an embodiment of the present application. Fig.12 The shrapnel 81 in the above Fig. 9Two limiting parts 813 are added on the basis of the middle spring piece 81, and a first extension part 8113 and a second extension part 8114 are also provided at the movable end 811c, and along the direction parallel to the bottom plate 812, the first extension part 8113 and the second extension part 8114 are respectively provided on both sides of the movable end 811c.
[0086] The two limiting portions 813 are respectively a first limiting portion 813a and a second limiting portion 813b, and the first limiting portion 813a and the second limiting portion 813b are respectively located on both sides of the movable end 811c. A first limiting groove 810a is formed between the first limiting portion 813a and the bottom plate 812, and a second limiting groove 810b is formed between the second limiting portion 813b and the bottom plate 812. The first extension portion 8113 extends into the first limiting groove 810a, and the second extension portion 8114 extends into the second limiting groove 810b.
[0087] In this way, it is equivalent to using the first limiting portion 813a to separate the first extension portion 8113 from the data card 90 and the main board 40, and using the second limiting portion 813b to separate the second extension portion 8114 of the movable end 811c from the data card 90 and the main board 40, thereby preventing the movable end 811c of the elastic arm 811 from driving the first extension portion 8113 and the second extension portion 8114 to scratch the main board 40 and the data card 90 when moving relative to the bottom plate 812.
[0088] In some cases, since the bottom plate 812 and the elastic arm 811 are generally made of metal, when the two spring sheets 81 are arranged close to each other, the bottom plates of the two spring sheets 81 may directly contact each other and cause a short circuit in the data card 90 .
[0089] In view of the above situation, in some embodiments, see Fig.13 As shown, Fig.13 The schematic diagram of the structure of another spring piece 81 provided in the embodiment of the present application. The spring piece 81 may further include an insulator 814.
[0090] The insulator 814 is disposed at the edge of the bottom plate 812, and the insulator 814 faces another adjacent spring sheet 81. It should be noted that the insulator 814 can cover the entire edge of the bottom plate 812, or can also cover a portion of the edge of the bottom plate 812, as long as it can insulate two adjacent spring sheets 81, and this application does not make any special limitation on this.
[0091] It is understandable that the above-mentioned insulator 814 can be an insulating paint sprayed on the base plate 812, or an insulating film attached to the base plate 812, or an insulating plastic layer injection-molded on the base plate 812, etc., and the present application does not make any special limitations on this.
[0092] For example, refer back to Figure 5 As shown, from Figure 5 It can be seen that in the length direction (Y-axis direction) of the electronic device 01, the distance between two adjacent spring pieces 81 is large, and the possibility of contact between the two to cause a short circuit is small, so there is no need to consider the insulation problem between the two. In the width direction (X-axis direction) of the electronic device 01, the distance between two adjacent spring pieces 81 is very small, and it is easy for them to contact each other and cause a short circuit.
[0093] For the reasons above, please continue to refer to Fig.13 As shown, Fig.13 The shrapnel 81 in the Fig.11 Two insulators 814 are added on the basis of the middle shrapnel 81. The two insulators 814 are respectively a first insulator 814a and a second insulator 814b. The first insulator 814a is arranged on the third wall plate 8123, and the second insulator 814b is arranged on the fourth wall plate 8124. The first insulator 814a and the second insulator 814b are both plastic layers formed by injection molding, that is, the first insulator 814a wraps the outer edge of the third wall plate 8123, and the second insulator 814b wraps the outer edge of the fourth wall plate 8124.
[0094] With such arrangement, in the width direction (X-axis direction) of the electronic device 01, even if two adjacent spring sheets 81 abut against each other, the insulators 814 on the two spring sheets 81 abut against each other, and the bottom plates 812 or elastic arms 811 of the two spring sheets 81 will not contact to cause a short circuit in the data card 90.
[0095] For example, suppose Figure 5 In the length direction (Y-axis direction) of the electronic device 01 , two adjacent spring pieces 81 are also close to each other.
[0096] At this time, see Fig.14 As shown, Fig.14 A schematic diagram of the structure of another spring piece 81 provided in an embodiment of the present application. Fig.14 The shrapnel 81 in the Fig.13 On the basis of the middle spring piece 81 , a third insulator 814 c is added to the outer edge of the first wall plate 8121 , and a fourth insulator 814 d is added to the outer edge of the second wall plate 8122 .
[0097] With such arrangement, in the length direction (Y-axis direction) of the electronic device 01 , even if two adjacent spring sheets 81 abut against each other, the insulators 814 on the two spring sheets 81 abut against each other, and the bottom plates 812 or elastic arms 811 of the two spring sheets 81 will not contact to cause a short circuit in the data card 90 .
[0098] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0099] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
