[0002] With the continuous development of science and technology, the functions of mobile terminals have become more and more. Therefore, mobile terminals with dual Subscriber Identity Module (SIM) cards have become very popular. The SIM card holder is a component in the mobile terminal for inserting the SIM card.

[0003] The card holder includes a base, a top cover and a card tray plugged into and installed on the base. The base and the top cover are generally used separately, so they are easy to fall off during use and have poor stability. Utility Model Content

[0004] In order to improve the stability of the card holder when in use, the present application provides a combined card holder.

[0005] The present application provides a combined card holder, which adopts the following technical solution:

[0006] A combined card holder comprises a base, a top cover and a card holder, wherein the top cover is connected to the base through a connecting mechanism, and the card holder is plugged and installed on the base, and the connecting mechanism comprises:

[0007] A clamping block, wherein the clamping block is arranged on the base, and a clamping groove for clamping with the clamping block is provided on the top cover;

[0008] A positioning assembly is arranged on the top cover and connected to the base and is used to position the base and the top cover and to guide and position the clamping block in the process of clamping the clamping slot.

[0009] By adopting the above technical solution, when in use, the card block is engaged and positioned with the card slot on the top cover, and at the same time, when the positioning component is connected to the base, it can guide when the card block and the top cover are plugged in, and the positioning component also connects the top cover and the base to each other after the card block and the card slot are engaged, and then the card tray is plugged and installed on the base for use, thereby improving the stability of the card holder when in use and the convenience of installation, and at the same time, the top cover, base and card tray can be disassembled by reverse operation, thereby also improving the convenience of disassembling the card holder.

[0010] Optionally, the positioning component includes:

[0011] The plug-in board and the positioning board are arranged on the top cover at intervals and are plug-installed on the base for positioning.

[0012] By adopting the above technical solution, the plug-in plate and the positioning plate are both plugged into the base for positioning and guiding, so that the card block can be aligned with the card slot to achieve guidance. At the same time, after the plug-in block, the positioning plate and the base are plugged in, the position of the top cover and the base can also be positioned.

[0013] Optionally, the top cover is pressed against the base and a plurality of pressing plates are formed on the side walls, and the plurality of pressing plates are pressed against a plurality of outer side walls of the base respectively under the action of elastic force, and the clamping groove is located on the pressing plates.

[0014] By adopting the above technical solution, multiple pressing plates are pressed against the outer wall of the base for positioning, so that the connection between the clamping block and the clamping slot is more firmly connected, the probability of the clamping block and the clamping slot being separated is reduced, and the stability of the clamping seat when in use is further improved.

[0015] Optionally, the plurality of pressure plates and the top cover form a placement chamber for placing the base, and the pressure plates are provided with support feet that are perpendicular to the pressure plates and away from the top cover. When the support feet are abutted against the installation object for fixed connection, they cooperate with the installation object to position the base and are used to prevent the base from moving in the placement chamber.

[0016] By adopting the above technical solution, the base is placed against the object to be installed, and the supporting feet are also placed against the object to be installed for positioning. At this time, the side wall of the base facing away from the object to be installed is placed against the bottom wall in the placement chamber for positioning. Finally, the supporting feet are fixedly connected to the object to be installed. At this time, the base is confined in the placement chamber, further reducing the probability of the snap-in block and the snap-in groove being detached. Therefore, while the card holder is fixedly installed, the stability of the card holder during use is also improved.

[0017] Optionally, the plug-in board protrudes out of the supporting foot and is used to be plugged in and matched with the installation object for positioning.

[0018] By adopting the above technical solution, the plug-in board is plugged into the installation object, so that the support feet are more easily aligned with the connection of the installation object, thereby improving the convenience of installing the card holder.

[0019] Optionally, the base is provided with a plug-in slot that cooperates with the card holder, the base is provided with a positioning slot that is connected to the plug-in slot and cooperates with the positioning plate, the card holder is provided with a limiting slot, and the positioning plate is provided with a limiting member that presses against the limiting slot for positioning under the action of elastic force.

[0020] By adopting the above technical solution, the positioning plate is plugged into the positioning slot for positioning, and the positioning plate drives the limiting piece to extend into the plug-in slot. When installing the card tray, the card tray is plugged into the plug-in slot. During the movement of the card tray, the limiting piece presses against the card tray for guiding positioning. After the card tray is plugged into place, the limiting piece presses against the limiting slot for positioning under the action of elastic force, thereby improving the stability of the card tray when in use, and further improving the stability of the card holder when in use.

[0021] Alternatively, the card holder is first plugged into the plug-in slot, and then when the top cover is connected to the base, the positioning plate is plugged into the positioning slot. When the positioning plate drives the limit piece to be plugged into the limit slot, the position of the top cover can also be guided and positioned. Therefore, the convenience of installing the top cover, base and card holder is improved, and the installation efficiency of the card holder is improved.

[0022] Optionally, the limiting member is a limiting sheet that is pressed against the limiting groove under the action of elastic force.

[0023] Optionally, a positioning surface is formed on the positioning plate for positioning against the side wall of the limiting groove formed on the card tray, and the limiting plate includes a first limiting portion and a second limiting portion that are interconnected and spaced apart along the card tray plug-in direction, and the card tray passes through the first limiting portion and the second limiting portion in sequence when plugged into the plug-in slot, the length of the first limiting portion is greater than the length of the second limiting portion, and the angle between the first limiting portion and the positioning surface is smaller than the angle between the second limiting portion and the positioning surface.

[0024] By adopting the above technical solution, when the card tray is inserted into the insertion slot, the card tray first contacts with the first limiting portion, and the angle between the first limiting portion and the positioning surface is small, so that it is convenient for the card tray to squeeze the first limiting portion, and as the card tray moves, the limiting plate is pressed against the limiting slot for positioning, and the angle between the second limiting portion and the positioning surface is large, which increases the force of pulling the card tray and squeezing the second limiting portion to move, making it easy for the card tray to be inserted into the insertion slot but difficult to withdraw from the insertion slot, further improving the convenience of installing the card tray and the stability after installation, and improving the convenience of installing the card tray and the stability of the card holder during use.

[0025] Optionally, the clamping block is provided with a guide angle for facilitating clamping and installation on the clamping groove.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] By engaging the card block with the card slot on the top cover to position it, the positioning component can guide the card block and the top cover when they are plugged in when connected to the base.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a combined card holder.

[0034] Reference Figure 1 and Figure 2 The combined card holder includes a base 1, a top cover 2 and a card tray 3 in a horizontal state. The top cover 2 is detachably connected to the base 1 through a connecting mechanism 4, and the card tray 3 is plugged and installed on the base 1. A limiting groove 31 is provided on the side wall of the card tray 3. At the same time, a limiting member is provided on the connecting mechanism 4, which is pressed against the limiting groove 31 for positioning under the action of elastic force.

[0035] The base 1 is a rectangular parallelepiped structure, and two bases 1 are provided and spliced ​​and fixed together. At the same time, a plug-in slot 11 is opened at one end of the base 1 along the length direction of the base 1. When the two bases 1 are spliced ​​and fixed, the contact terminal is clamped between the two for fixing. The contact terminal is used to press against the SIM card to realize electrical signal transmission; the card tray 3 is plugged and installed on the plug-in slot 11, and two positioning slots 12 are opened on the upper surface of the base 1 along the length direction perpendicular to the plug-in slot 11. The positioning slots 12 are opened along the length direction of the plug-in slot 11. A mounting plate 13 is fixedly installed on the side wall of the base 1 close to the opening of the plug-in slot 11, and a plug-in space 14 is formed between the mounting plate 13 and the side wall of the base 1.

[0036] Reference Figure 1 and Figure 2The connection mechanism 4 includes a clamping block 41 and a positioning assembly 5. The clamping block 41 is fixedly installed on the three side walls of the base 1 without the plug-in slot 11, and multiple clamping blocks 41 are arranged at intervals on each side wall of the base 1; a guide angle 42 is arranged at the top of the clamping block 41, and the guide angle 42 extends from the side of the clamping block 41 away from the base 1 to the side wall of the base 1. The top cover 2 is bent to form three pressure plates 21, and the three pressure plates 21 are arranged one by one with the three side walls of the base 1 provided with the clamping blocks 41. The pressure plates 21 are in a horizontal state and have a certain elasticity.

[0037] The three pressure plates 21 and the top cover 2 form a concave placement chamber 22, and the base 1 is snap-fitted and installed on the placement chamber 22, so that the three pressure plates 21 are respectively pressed against the three side walls of the base 1, or, the three pressure plates 21 are respectively pressed against the three side walls of the base 1 under the action of elastic force. At the same time, the pressure plates 21 and the corresponding parts of the snap-fit ​​blocks 41 are provided with snap-fit ​​grooves 23 that pass through the two opposite walls of the pressure plates 21. The snap-fit ​​blocks 41 are snap-fitted and installed on the snap-fit ​​grooves 23 for positioning, and the guide angles 42 are used for guiding when the snap-fit ​​blocks 41 are snap-fitted and installed on the snap-fit ​​grooves 23, so that the snap-fit ​​blocks 41 can be easily snap-fitted and installed on the snap-fit ​​grooves 23.

[0038] Reference Figure 1 and Figure 2 A horizontal supporting foot 24 is formed on the lower surface of the pressing plate 21 and is away from the top cover 2. The supporting foot 24 is perpendicular to the pressing plate 21. The supporting foot 24 is used to press against the installation object for positioning when installing the card holder, and then screws are passed through the supporting foot 24 to fix it to the installation object. At this time, the lower surface of the base 1 also presses against the installation object, and the upper surface of the base 1 presses against the bottom wall of the placement chamber 22, that is, the top cover 2 for positioning, so as to prevent the base 1 from moving in the placement chamber 22, so that the position of the clamping block 41 and the clamping groove 23 is more stable, thereby improving the stability of the card holder when in use; at the same time, the supporting foot 24 guides the base 1 when it is moved into the placement chamber 22, which is more convenient for the installation of the card holder.

[0039] The connecting mechanism 4 also includes a positioning component 5, which includes a plug-in board 51 and a positioning board 52. The plug-in board 51 is formed on the lower surface of the top cover 2 by bending and is in a vertical state. The plug-in board 51 is plugged and installed in the plug-in space 14 for positioning. At the same time, the plug-in board 51 extends downward to the bottom of the base 1. When the supporting foot 24 is connected to the installation object, the plug-in board 51 is first plugged and positioned with the installation object, so that the supporting foot 24 can be more easily aligned with the connection point of the installation object. Therefore, the plug-in board 51 has a positioning and guiding effect, which improves the stability of the use of the card holder and the convenience during installation.

[0040] There are two positioning plates 52 and they correspond to the two positioning grooves 12 one by one.

At the same time, the opposite side walls of the two positioning plates 52, that is, the side walls close to the pressure plates 21, abut against the positioning grooves 12; the limiting member is a limiting plate 6, which is formed by stamping the positioning plates 52 and protruding from the opposite side walls of the two positioning plates 52. There is a gap between the opposite side walls of the two positioning plates 52 and the positioning grooves 12 to facilitate the passage of the limiting plate 6. At the same time, when the base 1 abuts against the top cover 2, the limiting plate 6 is located in the plug-in groove 11.

[0041] There are two limit grooves 31 and limit plates 6, and they are respectively arranged in one-to-one correspondence with the two positioning plates 52. The two limit grooves 31 are located on the opposite side walls of the card tray 3; the limit plate 6 includes a first limit portion 61 and a second limit portion 62 that are interconnected and spaced apart along the length direction of the plug-in slot 11. The side wall of the positioning plate 52 that contacts the card tray 3 is a positioning surface 63. The length of the first limit portion 61 is greater than the length of the second limit portion 62, and the angle between the first limit portion 61 and the positioning surface 63 is smaller than the angle between the second limit portion 62 and the positioning surface 63. After the card tray 3 is plugged and installed on the plug-in slot 11, it passes through the first limit portion 61 and the second limit portion 62 in sequence. When the card tray 3 is against the bottom of the plug-in slot 11 for positioning, the first limit portion 61 and the second limit portion 62 are pressed against the limit groove 31 for positioning.

[0042] Reference Figure 1 and Figure 3 The base 1 can also be designed as a split type. The base 1 includes a lower body 71 and an upper body 72 that are buckled or spliced ​​with each other. The base 1 also includes a lower terminal 73 fixedly installed on the lower body 71 and an upper terminal 74 fixedly installed on the upper body 72. The lower body 71 and the upper body 72 cooperate to form a plug-in slot 11, and the upper terminal 74 and the lower terminal 73 cooperate to form a contact terminal, which presses against the SIM card to realize electrical signal transmission.

[0043] The working principle of the embodiment of the present application is as follows:

[0044] During installation, the two positioning plates 52 are plugged into the two positioning grooves 12, and the plug-in plate 51 is plugged into the plug-in space 14. The three limiting plates 6 are pressed against the side walls of the base 1, and the top cover 2 is pushed to move until the base 1 is against the top cover 2 for positioning, and the snap-in block 41 is snap-in installed on the snap-in groove 23 for positioning. Then the card holder 3 is plugged into the plug-in groove 11, and the limiting plate 6 is pressed against the limiting groove 31 for positioning. The plug-in plate 51 is plugged into the installation object, and the top cover 2 is pushed so that the supporting feet 24 and the base 1 are against the installation object. The screws are threaded through the installation object and connected to the installation object for positioning, so as to fix the installation socket, thereby improving the convenience of installing the socket and the stability during use.
