[0029] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0030] This application discloses a compact IC card socket 100.

[0031] Reference Figures 1-4 The compact IC card holder 100 according to the embodiments of this application includes: a housing assembly 1, a card reader assembly 2, and a circuit board 3.

[0032] The housing assembly 1 includes a first housing 11, a second housing 12, and a connector 13. The outer peripheral wall of the first housing 11 and / or the outer peripheral wall of the second housing 12 are provided with metal fasteners 14. The metal fasteners 14 are used to strengthen the structural strength of the first housing 11 or the second housing 12. The first housing 11 and the second housing 12 are opposite to each other and are in a stop-fitting relationship. The connector 13 is snapped between the outer peripheral wall of the first housing 11 and the outer peripheral wall of the second housing 12. The connector 13 is used to fix the first housing 11 and the second housing 12, and the connector 13 is electrically connected to the metal fasteners 14. A receiving groove 121 is defined between the first housing 11 and the second housing 12, and the opening of the receiving groove 121 is located on the side wall of the first housing 11 and the side wall of the second housing 12. The receiving groove 121 is used to insert an IC card.

[0033] It should be noted that the connector 13 is made of a conductive metal material.

[0034] In some specific embodiments, the outer peripheral wall of the first housing 11 is provided with a metal fastener 14, while the outer peripheral wall of the second housing 12 is not provided with a metal fastener 14.

[0035] In some other specific embodiments, the outer peripheral wall of the second housing 12 is provided with a metal fastener 14, while the outer peripheral wall of the first housing 11 is not provided with a metal fastener 14.

[0037] The card reader component 2 is disposed in the receiving slot 121. The card reader component 2 is adapted to communicate with the IC card. The circuit board 3 is connected and cooperates with the connector 13, and the connector 13 is electrically connected to the ground wire of the circuit board 3. The circuit board 3 communicates with the card reader component 2. The circuit board 3 obtains the data of the IC card through the card reader component 2. Specifically, when the IC card is inserted into the receiving slot 121, the circuit board 3 obtains the data of the IC card through the card reader component 2.

[0038] It should be noted that the compact IC card holder 100 is installed inside the POS machine, and the circuit board 3 is connected to the data interaction module of the POS machine.

[0039] When assembling the compact IC card holder 100, firstly align the first housing 11 and the second housing 12, then attach the first housing 11 and the second housing 12 together. By snapping the connector 13 between the outer peripheral walls of the first housing 11 and the second housing 12, that is, by placing the connector 13 across the first housing 11 and the second housing 12, the connector 13 is fixedly connected to the first housing 11 and the second housing 12. Then, the circuit board 3 is connected and engaged with the connector 13, and the connector 13 is electrically connected to the ground wire of the circuit board 3, thereby completing the assembly of the compact IC card holder 100.

[0040] Therefore, by fixing the first housing 11 and the second housing 12 to the circuit board 3 via the connector 13, and by fixing the first housing 11 and the second housing 12 to the circuit board 3 via the connector 13, and by electrically connecting the metal fastener 14 to the ground wire of the circuit board 3 via the connector 13, compared with the prior art, it is not necessary to fix the first housing 11, the second housing 12 and the circuit board 3 with screws, and it is also not necessary to set additional wires or metal parts to achieve the ground wire electrical connection between the housing and the circuit board 3, thereby reducing the assembly complexity of the compact IC card socket 100 and improving the assembly efficiency of the compact IC card socket 100.

[0041] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, the connector 13 includes a first snap-fit ​​portion 131, a second snap-fit ​​portion 132, and a connecting portion 133. The connecting portion 133 is connected between the first snap-fit ​​portion 131 and the second snap-fit ​​portion 132, and the central axis of the first snap-fit ​​portion 131 and the central axis of the second snap-fit ​​portion 132 both have an angle with the central axis of the connecting portion 133.

[0042] Along the height direction of housing assembly 1, the height direction of housing assembly 1 can refer to... Figure 2In the vertical direction, the first housing 11 is located above the second housing 12, the circuit board 3 is located below the second housing 12, the first snap-fit ​​part 131 is located above the connecting part 133, the second snap-fit ​​part 132 is located below the connecting part 133, and the connecting part 133 is opposite to the side wall of the first housing 11 and the side wall of the second housing 12.

[0043] In some specific embodiments, the included angle between the central axis of the first snap-fit ​​portion 131 and the central axis of the connecting portion 133 is 90°, and the included angle between the central axis of the second snap-fit ​​portion 132 and the central axis of the connecting portion 133 is 90°.

[0044] Furthermore, the first snap-fit ​​portion 131 is opposite to the first housing 11 and snaps into the first housing 11, and the second snap-fit ​​portion 132 is opposite to the second housing 12 and snaps into the second housing 12.

[0045] The first snap-fit ​​portion 131 engages with the first housing 11, and the second snap-fit ​​portion 132 engages with the second housing 12. The connecting portion 133 connects the first snap-fit ​​portion 131 and the second snap-fit ​​portion 132, thereby achieving the technical effect of fixing the first housing 11 and the second housing 12 using the connecting piece 13. Compared with fixing the first housing 11 and the second housing 12 using screws, the operator can directly assemble the connecting piece 13, the first housing 11 and the second housing 12 by hand, without the need to use additional tools such as screwdrivers to assemble the first housing 11 and the second housing 12. This reduces the assembly complexity of the compact IC card holder 100 and improves the assembly efficiency of the compact IC card holder 100.

[0046] It should be noted that the first snap-fit ​​part 131 and / or the second snap-fit ​​part 132 and / or the connecting part 133 are electrically connected to the metal fastener 14.

[0047] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, the end wall of the first housing 11 away from the second housing 12 has a first snap-fit ​​protrusion 111, and the first snap-fit ​​portion 131 is provided with a first snap-fit ​​groove 1311, which engages with the first snap-fit ​​protrusion 111. The end wall of the second housing 12 away from the first housing 11 has a second snap-fit ​​protrusion 122, and the second snap-fit ​​portion 132 is provided with a second snap-fit ​​groove 1321, which engages with the second snap-fit ​​protrusion 122.

[0048] After the first housing 11 and the second housing 12 are engaged, the connector 13 moves closer to the first housing 11 and the second housing 12. The first snap-fit ​​portion 131 abuts against the first snap-fit ​​protrusion 111, and the second snap-fit ​​portion 132 abuts against the second snap-fit ​​protrusion 122. Then, the first snap-fit ​​portion 131 and the second snap-fit ​​portion 132 both elastically deform in the direction away from the receiving groove 121. The first snap-fit ​​protrusion 111 extends into the first snap-fit ​​groove 1311, and the second snap-fit ​​protrusion 122 extends into the second snap-fit ​​groove 1321, thereby realizing the snap-fit ​​engagement between the connector and the first housing 11 and the second housing 12.

[0049] By engaging the first snap-fit ​​groove 1311 with the first snap-fit ​​protrusion 111 and engaging the second snap-fit ​​groove 1321 with the second snap-fit ​​protrusion 122, the connector 13 can be stably engaged with the first housing 11 and the second housing 12, thereby reliably connecting the first housing 11 and the second housing 12 without the need for screw fixing, thus improving the assembly efficiency of the compact IC card holder 100.

[0050] In some specific embodiments, there are multiple first snap-fit ​​slots 1311 and multiple first snap-fit ​​protrusions 111. The multiple first snap-fit ​​slots 1311 and multiple first snap-fit ​​protrusions 111 are all spaced apart along the circumferential direction of the housing assembly 1, and the multiple first snap-fit ​​slots 1311 and multiple first snap-fit ​​protrusions are arranged in a one-to-one correspondence.

[0051] In some specific embodiments, there are multiple second snap-fit ​​slots 1321 and multiple second snap-fit ​​protrusions 122. The multiple second snap-fit ​​slots 1321 and multiple second snap-fit ​​protrusions 122 are all spaced apart along the circumferential direction of the housing assembly 1, and the multiple second snap-fit ​​slots 1321 and multiple second snap-fit ​​protrusions are arranged in a one-to-one correspondence.

[0052] Reference Figure 1 , Figure 3 and Figure 4 In some embodiments of this application, the connector 13 is provided with a grounding part 134. Specifically, the grounding part 134 is located on the end wall of the connector 13 near the second housing 12. The circuit board 3 is provided with a grounding hole 31, which is electrically connected to the ground wire of the circuit board 3. Along the height direction of the housing assembly 1, the grounding part 134 is opposite to the grounding hole 31. The grounding part 134 is inserted into the grounding hole 31 and is electrically connected to the grounding hole 31.

[0053] After the connector 13 is connected and engaged with the housing assembly 1, the grounding part 134 is inserted into the grounding hole 31. The outer surface of the grounding part 134 makes sliding contact with the inner wall of the grounding hole 31. Under the action of the insertion force, the grounding part 134 is fully inserted into the grounding hole 31. The inner wall of the grounding hole 31 and the conductive surface of the grounding part 134 are tightly attached to form a stable contact, thereby establishing a conductive path.

[0054] The current of the connector 13 is transmitted to the ground wire of the circuit board 3 through the grounding part 134 and the grounding hole 31, so that the connector 13 and the circuit board 3 can be reliably connected. This ensures that the static electricity of the housing assembly 1 is discharged in time through the grounding path, and guarantees the overall electrical shielding performance and signal transmission stability of the compact IC card socket 100.

[0055] Reference Figure 5 and Figure 6 In some embodiments of this application, the end walls of the first housing 11 and the second housing 12 opposite to each other are provided with a first guide structure 112, and the end walls of the second housing 12 opposite to the first housing 11 are provided with a second guide structure 123, and the first guide structure 112 and the second guide structure 123 are guided and cooperated.

[0056] In some specific embodiments, the first guide structure 112 can be configured as a guide protrusion, and the second guide structure 123 can be configured as a guide recess.

[0057] In some specific embodiments, the first guide structure 112 can be configured as a guide recess, and the second guide structure 123 can be configured as a guide protrusion.

[0058] In some specific embodiments, there are multiple first guide structures 112 and multiple second guide structures 123. The multiple first guide structures 112 and multiple second guide structures 123 are spaced apart along the circumferential direction of the housing assembly 1, and the multiple first guide structures 112 and multiple second guide structures 123 are arranged in a one-to-one correspondence.

[0059] During the assembly of housing assembly 1, the first housing 11 and the second housing 12 gradually approach each other, the first guide structure 112 and the second guide structure 123 come into contact, and the first guide structure 112 and the second guide structure 123 guide each other to make the first housing 11 and the second housing 12 approach each other along a preset motion trajectory, thereby achieving a stop-and-go fit between the first housing 11 and the second housing 12.

[0060] The first guide structure 112 and the second guide structure 123 cooperate to achieve a limiting and guiding function, so that the first housing 11 and the second housing 12 are aligned before the stop engagement, avoiding the housing assembly 1 from shifting or tilting during the assembly process, thereby ensuring that the connector 13 can be accurately engaged between the outer peripheral walls of the first housing 11 and the second housing 12, and achieving efficient assembly and stable positioning of the housing assembly 1.

[0061] Reference Figure 5 and Figure 6In some embodiments of this application, the end wall rings of the first housing 11 and the second housing 12 opposite to each other are provided with sealing portions 113, and the end wall rings of the second housing 12 and the first housing 11 opposite to each other are provided with sealing grooves 124. The sealing grooves 124 are opposite to the sealing portions 113, and the sealing portions 113 are adapted to extend into the sealing grooves 124. The sealing portions 113 are used to seal the sealing grooves 124, and a sealing adhesive is provided between the sealing grooves 124 and the sealing portions 113.

[0062] The sealing part 113 of the first housing 11 is aligned with the sealing groove 124 of the second housing 12. The sealing part 113 gradually extends into the internal space of the sealing groove 124 and fits against the inner wall of the sealing groove 124. The sealing colloid between the sealing part 113 and the sealing groove 124 is compressed and filled under the action of compression, thereby realizing the sealed connection between the first housing 11 and the second housing 12. This can prevent liquids and debris in the external environment from entering the receiving groove 121 and improve the sealing performance of the housing assembly 1.

[0063] In some specific embodiments, the sealing compound can be a sealing ring made of epoxy resin.

[0064] Reference Figure 1 In some embodiments of this application, there are multiple connectors 13, which are spaced apart along the circumferential direction of the housing assembly 1. The multiple connectors 13 together fix the first housing 11 and the second housing 12. The first housing 11 and the second housing 12 can be relatively fixed in multiple positions, thereby preventing the first housing 11 and the second housing 12 from separating in some areas, preventing impurities and liquids in the external environment from entering the receiving tank 121, and improving the connection reliability between the first housing 11 and the second housing 12.

[0065] Reference Figure 2 and Figure 7 In some embodiments of this application, the card reader assembly 2 includes a plurality of card reader terminals 21. The first housing 11 or the second housing 12 is provided with a plurality of first receiving holes 114. The plurality of first receiving holes 114 and the plurality of card reader terminals 21 are spaced apart along the radial direction of the housing assembly 1 and are arranged in a one-to-one correspondence. The first receiving holes 114 communicate with the receiving groove 121. The card reader terminals 21 are disposed in the first receiving holes 114 and extend into the receiving groove 121. The card reader terminals 21 are communicatively connected to the circuit board 3 and are used to read the data of the IC card.

[0066] When the IC card is inserted into the receiving slot 121, multiple card reading terminals 21 sequentially contact the metal contacts of the IC card to form an electrical signal path. The multiple card reading terminals 21 transmit the data signal output by the IC card to the circuit board 3. After receiving the data signal, the circuit board 3 identifies and processes it, thereby realizing the reading of IC card information.

[0067] By providing multiple card reader terminals 21 within the receiving slot 121, it is ensured that the IC card can make full contact with the IC card when inserted into the card reader terminal 21, thus guaranteeing the stability of signal acquisition and the reliability of data transmission, and keeping the compact IC card holder 100 in a reliable reading state.

[0068] Reference Figure 7 In some embodiments of this application, the card reader assembly 2 further includes: a control switch 22 and a trigger spring 23. The first housing 11 or the second housing 12 is provided with a second receiving hole 115, which communicates with the receiving groove 121. The control switch 22 and the trigger spring 23 are both provided in the second receiving hole 115. The trigger spring 23 is located on the side of the control switch 22 near the receiving groove 121. The trigger spring 23 is opposite to the control switch 22 and is adapted to a stop engagement. The trigger spring 23 is adapted to elastic deformation and its end extends into the receiving groove 121. When the IC card is inserted into the receiving groove 121, the trigger spring 23 is driven to move closer to the control switch 22. The control switch 22 is communicatively connected to the circuit board 3. When the control switch 22 is triggered by the trigger spring 23, the circuit board 3 obtains the data of the IC card through the card reader assembly 2.

[0069] The IC card pushes the trigger spring 23 to elastically deform towards the control switch 22. The end of the trigger spring 23 gradually approaches the control switch 22 and eventually forms a stop contact with the control switch 22. The control switch 22 is triggered by the trigger spring 23 and transmits the trigger signal to the circuit board 3. After receiving the trigger signal from the control switch 22, the circuit board 3 activates the card reader component 2. The card reader component 2 begins to communicate with the IC card and collect the data information of the IC card.

[0070] By triggering the control switch 22 through the trigger spring 23, and using the control switch 22 to control the card reader 2 to acquire IC card data, automatic identification and data reading can be achieved the moment the IC card is inserted, avoiding energy waste caused by manual operation or continuous power supply, and improving the data acquisition response speed and ease of use of the compact IC card socket 100.

[0071] In some embodiments of this application, the first housing 11 or the second housing 12 and the metal fastener 14 are constructed as an integrally formed part.

[0072] In some specific embodiments, the first housing 11 or the second housing 12 and the metal fastener 14 are formed simultaneously by in-mold insert injection molding.

[0073] By constructing the first housing 11 or the second housing 12 and the metal fastener 14 as an integral part, there is no need to assemble the metal fastener 14 later, thereby ensuring the relative positional accuracy of the metal fastener 14 with the first housing 11 and the second housing 12, and improving the overall structural strength and assembly efficiency of the housing assembly 1.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
