Description

Technical Field

[0001] This utility model relates to the field of electronic components technology, and in particular to a card tray device and an electronic device. Background Technology

[0002] Currently, card slots or card slot connectors are used to realize the electrical connection between cards (SIM cards or memory cards) and the circuit boards (PCB boards) inside electronic products (mobile phones, etc.). The commonly used card slot structure includes a plastic shell with a accommodating space, an iron shell that snaps into the plastic shell to form a card slot, and multiple terminals positioned inside the plastic shell. The terminals include a terminal body portion embedded in the plastic shell, an elastic arm portion that is higher than the plane of the plastic shell, and a contact head located at the end of the elastic arm portion that abuts against the terminal and conducts electricity.

[0003] To accommodate both small and large SIM cards in mobile phones, a card tray or sleeve is typically used when using a small SIM card. The small SIM card is placed in the tray or sleeve before being inserted into the card slot. However, in current card slots on the market, the terminals that contact the card for electrical contact have short heads that protrude above the plastic housing of the card slot. When the card tray is installed or removed, it is easy for the card tray to impact the terminal head and damage the terminal, resulting in pin breakage / pin crossing. This can damage the terminal and even the card tray. If the terminal is bent or broken, it will affect the function of the card slot, rendering the entire card slot unusable. Utility Model Content

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figures 1 to 4 As shown, some embodiments of this application provide a card tray device having intersecting first direction X, second direction Y and third direction Z, which is mainly used in mobile terminals to prevent PIN corruption during card insertion or removal.

[0035] It should be noted that "pin collapse" refers to the phenomenon where terminals in a connector assembly deform or become damaged during mating. This phenomenon can lead to unstable connections or even complete failure.

[0036] The card tray device includes a frame 100 and a card tray cap 200. The connection method between the frame 100 and the card tray cap 200 includes any one of bonding, snap-fitting, bolting, sliding connection, or integral molding. In this embodiment, the frame 100 and the card tray cap 200 are integrally molded to improve the stability and overall strength of the card tray device.

[0037] The frame 100 has an opening 110 that extends through the frame 100 in a third direction Z, and the opening 110 is located in the middle of the frame 100.

[0038] Along the first direction X, a guide platform 120 is provided at one end of the frame 100. In this embodiment, the card tray device can be connected to the card slot in the mobile terminal, so as to provide guidance during the installation or removal of the card tray device and the card slot through the guide platform 120, so as to prevent the PIN from being broken during the installation or removal process, and improve the stability and smoothness of the installation or removal of the card tray device and the card slot.

[0039] It should be noted that, in this embodiment, the frame 100 is used to carry a memory card or an electronic card.

[0040] In this embodiment, the guide platform 120 includes a first guide surface 121, a connecting surface 122, and a second guide surface 123 connected to each other. The first guide surface 121, the connecting surface 122, and the second guide surface 123 are smoothly connected in sequence to form the outer surface of the guide platform 120 on one side along the third direction Z.

[0041] The first guide surface 121 is adjacent to the opening 110, and the second guide surface 123 is disposed on the side of the connecting surface 122 opposite to the opening 110. The angles between the first guide surface 121 and the second guide surface 123 and the connecting surface 122 are acute angles.

[0042] For example, when the card tray device is installed on the card holder, the second guide surface 123 can contact a portion of the pins on the card holder and provide a guiding function to prevent the side of the guide platform 120 away from the card tray cap 200 from directly hitting the end of this portion of the pins and causing pin breakage. It can also ensure the smooth connection between the card tray device and the card holder.

[0043] For example, when the card tray device is removed from the card holder, the first guide surface 121 can contact another part of the pins on the card holder and provide a guiding function to prevent the guide platform 120 from directly hitting the end of the other part of the pins on the side facing the card tray cap 200 and causing pin breakage, thereby ensuring the smooth connection between the card tray device and the card holder.

[0044] Additionally, a card holder 200 is disposed on one side of the frame 100 along the first direction X, and the card holder 200 and the guide platform 120 are respectively located on two opposite sides of the frame 100 so that the card holder 200 can pass through.

[0045] like Figure 1 and Figure 2As shown in some embodiments of this application, along the first direction X, the cross-sectional area of ​​the guide platform 120 increases progressively from the first guide surface 121 and the second guide surface 123 to the connecting surface 122, so as to ensure that the first guide surface 121 and the second guide surface 123 can respectively provide guidance for the PIN pins on the card holder, thereby avoiding the two ends of the guide platform 120 directly abutting the PIN pins along the first direction X, preventing PIN breakage, and ensuring the stability and smoothness of the installation or disassembly process between the card tray device and the card holder.

[0046] The angle between the first guide surface 121 and the connecting surface 122 is α, where the value of α is in the range of 30°≤α≤60°, to ensure that the first guide surface 121 can provide guidance for the PIN and prevent the guide platform 120 from directly contacting the PIN. Similarly, the angle between the second guide surface 123 and the connecting surface 122 is β, where the value of β is in the range of 30°≤β≤60°, to ensure that the second guide surface 123 can provide guidance for the PIN and prevent the guide platform 120 from directly contacting the PIN.

[0047] In addition, the first guide surface 121 and the second guide surface 123 are respectively one of the inclined surface, the arc surface or the curved surface, which can be specifically set according to the actual situation.

[0048] In this embodiment, both the first guide surface 121 and the second guide surface 123 are inclined surfaces, which form a guiding effect on the PIN pin through the inclined surfaces, thereby preventing the guide platform 120 from directly abutting the PIN pin along the side wall of the first direction X during the installation or removal of the card tray structure on the card holder, thereby ensuring the stability, safety and smoothness of the card tray device and card holder during the installation or removal process.

[0049] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the first guide surface 121, the connecting surface 122, and the second guide surface 123 extend along the second direction Y, that is, the length directions of the first guide surface 121, the connecting surface 122, and the second guide surface 123 are parallel to the second direction Y. It can be understood that by increasing the length of the first guide surface 121 and the second guide surface 123, the guiding area of ​​the lead frame is increased, thereby increasing the number of pins guided by the guide frame 120.

[0050] like Figure 2As shown, in some embodiments of this application, the inner wall of the frame 100 is provided with a limiting step 300. This limiting step 300 is located on one side of the frame 100 along the Z-direction, providing support for the memory card and simultaneously limiting its position within the frame 100. It is understood that the limiting step 300 and the inner wall of the frame 100 are connected to form a mounting groove on the inner side of the frame 100, thereby limiting the memory card's position within the frame 100 and ensuring its stability.

[0051] It should be noted that, along the third direction Z, the depth of the mounting slot is equal to or greater than the thickness of the memory card and the electronic card, so as to ensure that the memory card or electronic card can be completely accommodated in the mounting slot, thereby improving the space utilization of the frame 100 and the compactness of the installation.

[0052] like Figures 1 to 3 As shown, in some embodiments of this application, the frame 100 is provided with a through hole 130 on the side near the card holder cap 200, and the through hole 130 penetrates the frame 100 along the second direction Y.

[0053] The wall of the through hole 130 protrudes from the side opposite to the card tray cap 200 to form a protrusion 400, so that the protrusion 400 can provide a limiting and abutting function for the memory card disposed inside the opening 110, thereby ensuring the stability of the memory card in the opening 110.

[0054] Additionally, it should be noted that in this embodiment, the opening 110 is polygonal or regular polygonal in shape. That is, the opening 110 has multiple apex corners, and one of the apex corners is set as a chamfer 111 to form a foolproof structure on the inner wall of the opening, so as to prevent incorrect installation during memory card installation, thereby ensuring the installation efficiency and accuracy of the memory card.

[0055] In some embodiments of this application, the protrusion 400 is an elastic protrusion 400. It is understood that the through hole 130 is provided so that when the protrusion 400 is subjected to the abutment force of the memory card, the protrusion 400 can undergo elastic deformation and store elastic potential energy. The protrusion 400 can deform in the direction of the through hole 130, thereby providing space for the deformation of the protrusion 400 through the through hole 130, ensuring that the protrusion 400 can undergo effective elastic deformation.

[0056] For example, when the memory card installed in the housing 100 is removed from the housing 100, the external force acting on the protrusion 400 is removed, and the protrusion 400 deforms towards the opening 110 under its own elastic force and returns to its initial state, so as to limit the memory card.

[0057] In some embodiments, the elastic protrusion 400 may be an elastic rubber part, an elastic silicone part, or an elastic plastic part, which may be specifically set according to the actual situation.

[0058] Optionally, in other embodiments, an elastic element is provided in the through hole 130. One end of the elastic element abuts against the side of the hole wall of the through hole 130 facing the card holder cap 200, and the other end of the elastic element abuts against the side of the hole wall of the through hole 130 away from the card holder cap 200. The elastic force direction of the elastic element is parallel to the first direction X, so as to provide an elastic force along the first direction X to the protrusion 400 through the elastic element.

[0059] For example, when a memory card is installed in the frame 100, the protrusion 400 deforms under the action of the memory card, that is, the protrusion 400 deforms towards the card tray cap 200 and squeezes the elastic element. At this time, the elastic element is compressed and stores elastic potential energy.

[0060] When the memory card is removed from the frame 100, the elastic member exerts a spring force on the protrusion 400 in the first direction X toward the side away from the card tray cap 200, so that the protrusion 400 protrudes toward the side away from the card tray cap 200 under the action of the elastic member, thereby restoring the protrusion 400 to its initial state, so that the protrusion 400 can limit the memory card again, thereby ensuring the stability of the memory card installed in the frame 100.

[0061] like Figure 1 and Figure 3 As shown, in some embodiments of this application, guide grooves 140 are respectively provided on opposite side walls of the frame 100 along the third direction Z. The guide grooves 140 extend along the first direction X, that is, the axis of the guide grooves 140 is parallel to the first direction X, so as to provide guidance and prevent mistaken connection during the connection of the card tray device and the card holder in the mobile terminal, and at the same time avoid reverse installation. It can be understood that the card tray device and the card holder in the mobile terminal are connected by sliding.

[0062] Along the first direction X, the end of the guide groove 140 away from the card tray cap 200 passes through the frame 100 to ensure that the side of the frame 100 away from the card tray cap 200 can be connected to the card slot in the mobile terminal.

[0063] like Figures 1 to 3As shown, in some embodiments of this application, along the second direction Y, the opposite side walls of the frame 100 are respectively provided with clearance grooves 150. The clearance grooves 150 are connected to the guide grooves 140, so as to provide clearance for the elastic limiting structure disposed inside the card holder through the clearance grooves 150, so that the elastic limiting structure inside the card holder can be locked in the clearance grooves 150, thereby limiting the frame 100 and ensuring the stability of the connection between the card holder device and the card holder.

[0064] like Figure 1 and Figure 2 As shown, in some embodiments of this application, along the second direction Y, one end of the card holder cap 200 is provided with a connecting hole 210, and the connecting hole 210 penetrates the card holder cap 200 along the first direction X.

[0065] The connecting hole 210 corresponds to the elastic limiting member in the card holder. During use, the card holder device is lightly pressed at one end of the connecting hole 210 with a pin, and the elastic limiting structure is pushed by the pin to move the elastic limiting structure out of the relief groove 150. The elastic force of the elastic limiting member pops the card holder device out of the card holder, thereby improving the convenience of removing the card holder device from the card holder.

[0066] In addition, some embodiments of this application provide an electronic device including the card tray device described in any of the above embodiments.

[0067] The card tray is used to connect with the card slot in electronic devices to ensure stability, smoothness and safety during the installation or removal process between the card tray and the card slot.

[0068] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0069] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0070] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
