Description

Technical Field

[0001] This technology mainly relates to the field of electronic device connector technology, specifically the structural design of IC card sockets. Background Technology

[0002] With the widespread use of electronic devices, IC cards, as a secure and convenient data storage and transmission medium, are widely used in various electronic devices. The IC card socket, as the connection interface between the IC card and the device, directly affects the user experience and the stability of data transmission. Currently, the design of IC card sockets mainly focuses on contact reliability, insertion and removal lifespan, and dust and water resistance. However, in actual use, dust, debris, and other foreign objects easily accumulate inside the IC card socket. These foreign objects can affect the normal insertion and contact of the IC card, and may even lead to device malfunction or data loss. Furthermore, some card sockets require manual disassembly for cleaning, which is time-consuming and labor-intensive. Utility Model Content

[0003] In order to effectively clean the dust and debris inside the IC card holder and save the time of manually disassembling and assembling the whole device to clean the IC card holder, this application provides a card holder that can exclude foreign objects.

[0004] The card holder that can exclude foreign objects provided in this application adopts the following technical solution: A card holder capable of rejecting foreign objects includes a base and a cover plate. The cover plate is located above the base. A first card slot is provided on one side of the base. A first through groove is provided on one side of the cover plate, penetrating the upper and lower surfaces. The base is engaged with the first through groove on the cover plate through the first card slot, forming a card slot in the middle that allows IC cards to pass through.

[0005] By adopting the above technical solution, the base and the cover plate are connected to form a card slot for IC card insertion. When there are loose debris such as dust and paper scraps inside the card slot that are not easy to clean, the IC card is inserted, pushing the debris inside the card slot. When the debris is pushed to the bottom of the card slot, because the bottom of the card slot is not fully closed, the debris will be pushed out by the IC card, thereby achieving the purpose of cleaning the inside of the card slot without manually disassembling the device, saving time and effort.

[0006] Preferably, a first buckle that bends away from the center of the base is provided on one side of the first locking part, and a plane is formed between the first through groove and the side of the cover plate. The plane is a first limiting part, and the first buckle engages with the first limiting part to limit the vertical displacement of the base and the cover plate.

[0007] By adopting the above technical solution, when the IC card is inserted, the first card slot will restrict the displacement of the IC card in the pushing direction.

[0008] Preferably, the base has a second locking part on its shorter two sides, and a second buckle that bends toward the center of the base is provided at one end of the second locking part. The cover plate has a U-shaped groove on its shorter two sides. When the base and the cover plate are assembled together, the second buckle engages with the U-shaped groove, further restricting the displacement of the base and the cover plate in the vertical direction.

[0009] By adopting the above technical solution, the overall stability of the card holder can be effectively improved, and the tightness of the engagement between the base and the cover plate can be enhanced.

[0010] Preferably, the card holder capable of excluding foreign objects includes a PCB board, the second card slot is connected to the PCB board, the PCB board is provided with a positioning groove corresponding to the second card slot, and the second card slot passes through the positioning groove for connection.

[0011] By adopting the above technical solution, when connecting the base and the PCB board, the second locking part passes through the positioning groove, and after the position is confirmed, the welding connection is carried out to effectively fix the connection between the base and the PCB board.

[0012] Preferably, a U-shaped support structure is provided on the longer side of the base, the U-shaped support structure is disposed on the lower surface of the base, the U-shaped support structure is bent toward the center of the base, and a ramp structure is provided on the other longer side of the base, the ramp structure is at a certain angle to the base.

[0013] By adopting the above technical solution, when the base is soldered to the PCB board, the lower surface of the base does not directly contact the PCB board. The U-shaped support structure and the ramp structure set on both sides of the lower surface of the base abut against the PCB board, which plays the role of supporting the base and enhancing the strength of the overall base structure.

[0014] Preferably, the middle portion of the cover plate is provided with several second through slots penetrating the upper and lower surfaces of the cover plate, and several contact terminals are connected to the upper surface of the longer side of the PCB board. The contact terminals are arranged in a regular pattern. The cover plate is provided with several third through slots corresponding to the contact terminals along one side of the length direction. The contact terminals are fixed to the PCB board by welding. The tail of the contact terminal passes through the third through slot at the connection point with the cover plate. One end of the contact point of the contact terminal is embedded in the second through slot.

[0015] By adopting the above technical solution, the contact terminal not only reads IC card information, but the tail end of the contact terminal soldered to the PCB board also serves to limit the IC card at the bottom of the card slot.

[0016] Preferably, a switch unit is provided on one side of the upper surface of the PCB board along its length. The switch unit consists of a switch spring and a switch terminal. The tail end of the switch terminal passes through a fourth through groove provided on the edge of the cover plate and is connected to the PCB board by welding.

[0017] By adopting the above technical solution, the switching unit is normally in the open state. When the IC card socket is inserted, the switch spring is squeezed and lifted upward, contacting the switch terminal, and the switching unit is in the normally closed state, thus forming a circuit.

[0018] Preferably, the base is made of stainless steel and the cover is made of plastic.

[0019] By adopting the above technical solutions, the stainless steel base enhances the overall stability of the card holder, and the plastic cover effectively provides insulation.

[0020] Preferably, the contact terminal is connected to the cover plate through in-mold injection molding, and the contact terminal and the cover plate are integrally formed, making the card holder more robust and secure.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The non-fully enclosed card slot structure formed by the base and cover plate allows the IC card to push out and remove debris from inside the card slot through the through groove at the bottom of the card slot. This eliminates the need for manual disassembly of the device for cleaning, saving time and effort, reducing equipment malfunctions caused by debris inside the card slot and the cost of maintaining the device, and improving the user experience. 2. Improved the success rate and contact stability of IC card insertion, and enhanced the overall strength of the card holder. Attached Figure Description

[0031] The following is in conjunction with Figure 1- Figure 7 This application will be described in further detail.

[0032] This application discloses a card holder capable of excluding foreign objects. (See Figure 1-) Figure 7The foreign object-removing holder provided in this embodiment includes a base 1 and a cover plate 2. In this embodiment, the base 1 is made of stainless steel, and the cover plate 2 is made of insulating plastic material. A first locking portion 10 is provided on the longer side of the base 1, wherein there are two or more first locking portions 10. A first buckle 100 is provided at the end of the first locking portion 10 away from the base, wherein the first buckle 100 is bent at a 90° angle away from the center of the base 1. A first through groove 20 penetrating the upper and lower surfaces is provided on the longer side of the cover plate 2, and a plane is provided between the through groove 20 and the side, which is the first limiting portion 22. The base 1 passes through the first locking portion 10 and the first buckle 100 and is tightly fastened to the first limiting portion 22 through the first through groove 20 of the cover plate 2. Second locking portions 12 are provided on the shorter sides of the base 1. A second buckle 120 is provided at the end of the second locking portion away from the base 1, facing the center of the base 1, and the second buckle 120 is bent at a 90° angle. The cover plate 2... The U-shaped grooves 24 provided on both sides along the width direction are joined by the second buckle 120 to form a splicing structure, creating a card slot that can accommodate the size of an IC card. The first limiting part 22 on the base 1 is connected to the positioning groove 30 on the PCB board 3 and fixed by welding or by buckle engagement. To avoid direct contact between the base 1 and the PCB board 3, a U-shaped support structure 14 and a ramp structure 16 are respectively provided on the lower surface of the base 1 to enhance the overall structural strength of the card holder. The PCB board 3 is also welded with contact terminals 32 and switch units 34 for reading and transmitting IC card information. The contact terminals 32 and the cover plate 2 are integrally formed by in-mold injection molding. The contact terminals 32 pass through the third through groove 27 on the longer side of the cover plate 2 and bend at a certain angle inside the card slot, embedding in the second through groove 26 that runs through the upper and lower surfaces of the cover plate 2. The card slot is not a fully enclosed structure. It is limited by the first card slot 10, the tail of the contact terminal 32 and the tail of the switch terminal 342. The displacement of the IC card in the insertion direction at the bottom of the card slot is restricted. The tail of the switch terminal 342 of the switch unit 34 passes through the fourth through slot 28 provided on the longer side of the cover plate and is fixed to the lower surface of the cover plate 2. When the IC card is inserted, the switch spring 340 is squeezed upward by the IC card and thus contacts the switch terminal 342 to form a circuit.

[0033] The beneficial effects of this embodiment are: it allows for cleaning of the inside of the IC card holder without disassembling it; simply inserting the IC card into the slot allows debris to be pushed out from the gap at the bottom of the slot, saving time and effort, and is simple and convenient. The various latches, support structures, contact terminals, and cover plates are integrated through in-mold injection molding, effectively improving the overall robustness and strength of the card holder.
