Description
Technical Field
[0001] The present application relates to the technical field of electronic device connection, and in particular to a reverse IC card socket. Background Art
[0002] As an integrated circuit card, IC card has been widely used in identity recognition, financial transactions, data storage and other fields. As a key component connecting IC card and electronic equipment, the performance stability and ease of use of IC card holder directly affect the application effect of IC card.
[0003] Traditional IC card holders usually set the terminals on the base. When the terminals are set on the base, the structure of the base needs to be designed to be compact to accommodate the terminals and ensure their electrical connection with the PCB. This will reduce the open space of the base, restrict the design of air circulation and heat dissipation paths. The terminals are set on the base, which affects the heat dissipation performance of the card holder, especially when used in a high temperature environment, which is prone to poor terminal contact or performance degradation.
[0004] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content
[0005] The purpose of this application is to set the terminal on the cover body, which can make the heat dissipation path more direct, and the heat can be conducted from the terminal to the cover body surface more quickly, and then transferred outward through the cover body surface, which can reduce thermal resistance and improve the heat dissipation efficiency of the IC card holder.
[0006] The above technical purpose of the present application is achieved through the following technical scheme: a reverse IC card socket, including a base, the base is installed on a PBC board, the base is provided with a cover body, the base and the cover body together form a plug-in slot for plugging in an IC card, the cover body is provided with a terminal, the cover body is provided with a through slot, and the through slot is arranged corresponding to the terminal.
[0007] By adopting the above technical solution, the terminal is set on the cover body, which is conducive to more directly conducting heat to the surface of the cover body. Through the corresponding installation of the through groove, the heat can be dissipated outward more effectively. This can improve the heat dissipation performance of the IC card holder, reduce the operating temperature, and extend the service life of the device. The insertion and removal of the IC card is more convenient, and the user can operate more intuitively, reducing the risk of reverse insertion. At the same time, since the IC card is in direct contact with the base, the insertion and removal action is more stable, reducing the possibility of poor contact and improving the user experience.
[0008] Optionally, the base is provided with mounting feet, the PBC board is provided with mounting holes, and the base is plugged into the mounting holes through the mounting feet.
[0009] By adopting the above technical solution, the base can be firmly fixed on the PCB board by plugging the mounting feet into the mounting holes on the PCB board, and it is not easy to loosen or shift, which helps to improve the reliability and stability of the equipment. The design of the mounting feet and the mounting holes makes the installation process of the base simpler and faster. The installer only needs to insert the mounting feet of the base into the mounting holes on the PCB board to complete the installation without the need for additional tools or complicated operations. By plugging the mounting feet into the mounting holes on the PCB board, a tight structural connection is formed between the base and the PCB board, which improves the stability and vibration resistance of the overall structure, helps to reduce the impact of vibration and vibration of the equipment on the base during transportation or use, and protects the electronic components inside the equipment from damage.
[0010] Optionally, a protrusion is provided on the mounting foot, and the protrusion and the mounting hole are interference fit.
[0011] By adopting the above technical solution, the interference fit between the protrusion and the mounting hole forms a tight connection, so that the mounting foot is more firmly fixed on the PCB board. This can effectively prevent the base from loosening or falling off during the operation of the equipment, and improve the reliability and stability of the equipment. The interference fit can ensure the precise fit between the mounting foot and the mounting hole, making the installation position of the base more accurate and stable. This helps to maintain the correct alignment between the various components of the equipment and improves the assembly accuracy of the overall equipment. The interference fit between the protrusion and the mounting hole forms a more secure connection that can withstand greater external impact and vibration loads, thereby enhancing the durability and fatigue resistance of the mounting foot. This extends the service life of the base and reduces the maintenance cost of the equipment.
[0012] Optionally, a calibration piece is provided on the cover body, and a calibration hole is provided on the PBC board, and the calibration piece can be embedded in the calibration hole.
[0013] By adopting the above technical solution, the design of the calibration piece and the calibration hole can ensure that the cover body is accurately aligned with the PCB board during the installation process. By embedding the calibration piece in the calibration hole, the cover body can be accurately positioned, ensuring the correct alignment between the various components of the equipment and improving the assembly accuracy. The matching design of the calibration piece and the calibration hole can reduce the possibility of human installation errors. Through the precise matching of the calibration piece and the calibration hole, installation deviations caused by inaccurate manual operation are avoided, and the accuracy and consistency of assembly are improved. Through precise alignment, it can be ensured that the terminals of the bottom cover body are correctly connected to the corresponding signal lines on the PCB board, optimizing the signal transmission effect and improving the performance and reliability of the equipment.
[0014] Optionally, a baffle is provided on the base, and the baffle is used to abut against the IC card. The IC card and the bottom of the insertion slot together form a receiving slot.
[0015] By adopting the above technical solution, by providing a baffle on the base, the IC card will not be inserted too deeply during the insertion process, ensuring that the card stays stably at the predetermined position, avoiding poor contact or damage to the card caused by too deep insertion. The arrangement of the receiving slot forms a space at the rear end of the card holder. When foreign matter such as dust and paper scraps accumulate and clump during long-term use, the foreign matter accumulates in the receiving slot, thereby preventing the foreign matter from obstructing the normal insertion of the IC card, thereby affecting the function and service life of the card holder.
[0016] Optionally, the base and the cover body are combined to form a through hole, and the through hole is connected to the accommodating groove.
[0017] By adopting the above technical solution, the conductive design of the through hole and the receiving groove helps to remove dust and impurities inside the base and the cover, keeping the inside of the device clean. This can reduce the accumulation and impact of dust on electronic components and reduce the frequency and cost of equipment maintenance.
[0018] Optionally, a first clamping member is provided on the base, a avoidance hole is provided on the cover, a second clamping member is provided at the avoidance hole, and the first clamping member and the second clamping member are engaged with each other.
[0019] By adopting the above technical solution, since the base and the cover are connected by a snap-fit method, it is more convenient and quick for maintenance personnel to maintain or replace parts. The corresponding parts can be easily disassembled or replaced by simply releasing the snap-fit, saving maintenance time and cost.
[0020] Optionally, a third clamping piece is provided on the base, and a fourth clamping piece is provided on the cover, and the third clamping piece and the fourth clamping piece are engaged with each other.
[0021] By adopting the above technical solution, the matching clamping between the third clamping member and the fourth clamping member provides a stable connection, which helps to prevent the device from loosening or falling off during transportation or use, and improves the stability and reliability of the device. The base and cover of the device are connected by a clamping method, which makes assembly and maintenance simpler and more convenient. Maintenance personnel can easily disassemble or replace parts without using additional tools or performing complicated operations.
[0022] Optionally, the base is provided with an engaging piece, the cover body is provided with an engaging groove, and the engaging piece can be engaged in the engaging groove.
[0023] By adopting the above technical solution, the design of the fitting and the fitting groove enables a stable connection between the base and the cover. This helps prevent the device from loosening or falling off due to vibration or external force during use, thereby improving the stability and reliability of the device. The design of the fitting and the fitting groove makes the assembly process of the base and the cover simpler and faster. The assembly can be completed by simply inserting the fitting into the fitting groove, without the need for additional tools or complicated operations, thus reducing assembly time and labor costs.
[0024] In summary, this application has at least the following beneficial effects:
[0025] 1. Setting the terminal on the cover is conducive to more direct heat conduction to the surface of the cover. Through the corresponding installation of the through slot, the heat can be dissipated more effectively. This can improve the heat dissipation performance of the IC card holder, reduce the operating temperature, and extend the service life of the equipment. The insertion and removal of the IC card is more convenient, and the user can operate more intuitively, reducing the risk of reverse insertion. At the same time, since the IC card is in direct contact with the base, the insertion and removal action is more stable, reducing the possibility of poor contact and improving the user experience.
[0026] 2. The interference fit between the raised parts and the mounting holes forms a tight connection, making the mounting feet more firmly fixed on the PCB board. This can effectively prevent the base from loosening or falling off during the operation of the equipment, and improve the reliability and stability of the equipment. The interference fit can ensure the precise fit between the mounting feet and the mounting holes, making the installation position of the base more accurate and stable. This helps to maintain the correct alignment between the various components of the equipment and improves the assembly accuracy of the overall equipment. The interference fit between the raised parts and the mounting holes forms a more secure connection that can withstand greater external impact and vibration loads, thereby enhancing the durability and fatigue resistance of the mounting feet. This extends the service life of the base and reduces the maintenance cost of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS
