Description

Technical Field

[0001] This utility model relates to a self-protection structure for the IC card slot of a POS machine, belonging to the field of POS machines. Background Technology

[0002] The IC card socket self-protection structure of a POS machine refers to a series of protective mechanisms and structures designed to ensure the security of the IC card socket and prevent illegal intrusion, data theft and physical damage. Specifically, these include fence frame protection structure, pin protection structure, tamper detection structure, baffle protection structure, etc.

[0003] The fence frame protection structure refers to the protection of the IC card socket on both sides by the core board and connector board. The sides of the IC card socket are protected by plastic plus PTF fence frame or PCB fence frame, which can prevent direct external attacks on the sides of the card socket.

[0004] While the addition of the aforementioned fence frame protection structure protects the IC card slot, it occupies space on the PCB board, potentially increasing the thickness of the POS machine and raising production costs.

[0005] Therefore, this utility model provides a self-protection structure for an IC card socket that integrates the IC card socket with modified composite plastic. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an IC card socket self-protection structure that integrates the IC card socket with the modified composite plastic.

[0007] This utility model is implemented as follows: A self-protection structure for an IC card socket of a POS machine includes a middle frame, a rigid printed circuit board, an IC card socket, contact springs, and a plastic film. The rigid printed circuit board is installed in the middle frame, and the IC card socket is detachably and fixedly connected to one side of the rigid printed circuit board. The IC card holder includes a first end face and a second end face; The first end face is covered with a plastic film, and the vertical ends of the plastic film can extend to the side of the IC card holder and the edge of the second end face. The horizontal ends of the plastic film are bent and extend to the end of the second end face. A contact spring is detachably and fixedly connected to the second end face of the IC card socket, and the pins of the contact spring conduct signals to the traces on the plastic film through thermoforming. When the IC card socket is fixed on the rigid printed circuit board, the contact spring is electrically connected to the rigid printed circuit board through a conductive rubber strip.

[0008] As a further improvement, the plastic film is thermoformed onto the IC card holder using a hot-pressing process.

[0009] As a further improvement, the plastic film is composed of a first plastic layer with security detection circuitry and a second plastic layer with signal detection circuitry for IC card sockets, with the second plastic layer covering the first end face and the first plastic layer exposed to the outside.

[0010] As a further improvement, both the first and second plastic layers of the plastic film are electrically connected via conductive rubber strips and a rigid printed circuit board.

[0011] As a further improvement, the contact spring includes a metal frame and a plurality of metal contacts disposed in the middle part of the metal frame, as well as a plurality of pins disposed on one side of the metal frame. The metal contact contacts the IC card to obtain IC card data information, and the other end of the pin is electrically connected to the rigid printed circuit board to transmit the obtained IC card data information to the rigid printed circuit board.

[0012] As a further improvement, the contact spring is a one-piece molded structure.

[0013] As a further improvement, the IC card holder is made of plastic or metal.

[0014] As a further improvement, several metal contacts are divided into groups, with the two groups of metal contacts arranged in parallel to each other.

[0015] The beneficial effects of this utility model are as follows: This utility model uses a plastic film with a security detection circuit integrated into the first end face of the IC card holder, completely covering the contact springs on the second end face of the IC card holder. Furthermore, the plastic film is electrically connected to a rigid printed circuit board, and the bottom of the contact springs is shielded by the rigid printed circuit board. Unlike traditional methods, it does not require a protective fence structure. Therefore, to detect sensitive signals on the IC card holder, the security detection circuit of the plastic film must first be disabled. If the plastic film is directly torn off, the security detection circuit will break, triggering a security alarm and rendering the device unusable. In other words, this utility model forms a self-protected whole for the IC card holder, eliminating the need for an additional PCB board to protect the IC card holder itself or its sides, thus improving design flexibility and reducing space occupation and production costs.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Reference Figures 1 to 5As shown, this embodiment provides a specific implementation of a self-protection structure for an IC card holder of a POS machine, including a middle frame 10, a rigid printed circuit board 20, an IC card holder 30, a contact spring 40, and a plastic film 50. The rigid printed circuit board 20 is installed in the middle frame 10, and the IC card holder 30 is detachably and fixedly connected to one side of the rigid printed circuit board 20. The IC card holder 30 includes a first end face 301 and a second end face 302; The first end face 301 is covered with a plastic film 50, and the vertical ends of the plastic film 50 can extend to the side of the IC card holder 30 and the edge of the second end face 302. The horizontal ends of the plastic film 50 are bent and extend to the end of the second end face 302. A contact spring 40 is detachably and fixedly connected to the second end face 302 of the IC card holder 30, and the pins of the contact spring 40 are in contact with the plastic film 50.

[0026] The above summarizes the necessary technical means for solving the necessary technical problems of this utility model. The key point of this utility model is that a plastic film 50 with a security detection circuit is integrated into the first end face 301 of the IC card holder 30, completely covering the contact spring 40 on the second end face 302 of the IC card holder 30. The plastic film 50 is also electrically connected to the rigid printed circuit board 20. The bottom end of the contact spring 40 is shielded by the rigid printed circuit board 20, eliminating the need for a protective fence structure as in the past. Therefore, if a sensitive signal on the IC card holder is to be detected, the security detection circuit of the plastic film 50 must first be disabled. If the plastic film 50 is directly torn off, the security detection circuit on it will break, causing a security trigger and rendering the device unusable. In summary, this utility model forms an IC card socket into a self-protected whole, eliminating the need for an additional PCB board to protect the IC card socket itself or its sides, thus improving design flexibility and reducing space occupation and production costs.

[0027] In this embodiment, the plastic film 50 is thermoformed onto the IC card holder 30 using a hot pressing process. Hot pressing is a processing technology that uses a combination of heating and pressurization to cause physical or chemical changes in materials, thereby forming a specific shape, structure, or achieving bonding between materials.

[0028] The method of fusing the plastic film 50 with the IC card holder 30 is not limited to hot pressing. Therefore, in other embodiments, the present invention may also include hot melt adhesive bonding process, vacuum forming bonding process, etc., as long as the plastic film 50 can be covered on the IC card holder 30 without detaching.

[0029] Furthermore, the plastic film 50 is composed of a first plastic layer with security detection lines and a second plastic layer with signal detection lines for IC card sockets. The second plastic layer covers the first end face 301, while the first plastic layer is exposed to the outside. The first plastic layer with security detection lines is used to detect the security lines, while the second plastic layer with signal detection lines for IC card sockets is used to transmit the IC card signal.

[0030] As a further improvement, both the first and second plastic layers of the plastic film 50 are electrically connected to the rigid printed circuit board 20 via the conductive rubber strip 60. In other words, the plastic film 50 is electrically connected to the rigid printed circuit board 20 via the conductive rubber strip 60 to ensure the normal use of the security detection circuit and the IC card signal circuit on the plastic film 50.

[0031] In this embodiment, the contact spring 40 includes a metal frame 401 and a plurality of metal contacts 402 disposed in the middle part of the metal frame 401, and a plurality of pins 403 disposed on one side of the metal frame 401. The pins 403 transmit IC card data information through the signal detection circuit of the second plastic layer to the rigid printed circuit board 20, and transmit the information read from the IC card to the internal module of the device for processing.

[0032] There is a small gap between the rigid printed circuit board 20 and the contact spring 40 for inserting an IC card, so that the metal contact 402 on the contact spring 40 can fully contact the IC card to read the information on the bank card.

[0033] The pins of the contact spring 40 conduct signals to the traces on the plastic film through a thermo-pressing method.

[0034] The metal contact 402 contacts the IC card to obtain IC card data information. The obtained IC card data information is transmitted through the signal detection circuit of the second plastic layer to the electric rubber strip 602, and then through the conductive rubber strip 60 to the rigid printed circuit board 20 for processing by the internal module of the device.

[0035] Among them, several metal contacts 402 are divided into two groups, and the two groups of metal contacts 402 are arranged in parallel to each other.

[0036] The IC card holder 30 and the middle frame 10, which are corresponding to the contact spring 40, are provided with IC card insertion slots for inserting IC cards into the device and making physical contact with the contact spring 40.

[0037] The IC cards mentioned here include, but are not limited to, bank cards and chip cards.

[0038] In the above description, the metal contact 402 makes physical contact with the IC card, reads the data information on the IC card, and transmits the information to the rigid printed circuit board 20 for processing through the pin 403. The above structural design not only ensures accurate positioning and stable contact after the IC card is inserted, but also simplifies operation and protects the card and the device.

[0039] In this embodiment, the contact spring 40 is a molded integral structure, which reduces the number of solder joints on the contact spring 40 and improves the efficiency of data processing.

[0040] In this embodiment, the IC card holder 30 is made of plastic or metal materials to reduce costs.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
