[0034] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the accompanying drawings:

[0035] In the description of the present invention, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. The orientation or position relationship indicated by the terms "portion", "side", "end", etc. is based on the orientation or position relationship shown in the drawings and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0036] like Figure 1 As shown, the present application provides a payment terminal with a magnetic head 2 waterproof structure, including a housing 100, an outer partition plate 103 is provided on one side of the housing 100, a card swiping slot 101 for swiping a card is formed between the outer partition plate 103 and the housing 100, and a brush head extending from the inner edge of the housing 100 is provided in the card swiping slot 101.

[0037] Specifically, refer to Figure 2 A mounting slot 102 is provided on one side of the housing 100 near the card swiping slot 101. The mounting slot 102 is used to install the magnetic head assembly. The mounting slot 102 is provided with a sealing cover 1. The sealing cover 1 is plugged into the mounting slot 102 to form an isolation chamber. The magnetic head assembly is installed inside the isolation chamber, which effectively prevents external impurities from entering the device and affecting the use of internal components, especially preventing water vapor, dust, salt spray, etc. from invading the mainboard, causing oxidation and short circuit of the mainboard. The above overall structure is simple, easy to install, has significant dustproof and waterproof effects, expands the application scenarios, and improves the service life of the equipment.

[0038] Furthermore, the magnetic head assembly includes a connecting wire 21, which extends to the outside of the isolation chamber and is electrically connected to the mainboard (the specific connection method is not shown in the figure). In a specific embodiment, the connecting wire 21 is an FPC cable.

[0039] like Figure 3-Figure 5 As shown, the head assembly also includes a head 2 and a bracket 3. The bracket 3 is used to install the head 2. The bracket 3 includes a top cover 31. The connection line 21 of the head 2 passes through the top cover 31 and the sealing cover 1 in sequence and is electrically connected to the mainboard.

[0040] Combination Figure 4 and Figure 5In a specific embodiment shown, the top cover 31 is provided with an annular protrusion 311 around the connecting line 21, and correspondingly, the lower end of the sealing cover 1 is provided with a plug hole 11. When the sealing cover 1 is plugged into the mounting groove 102, the annular protrusion 311 is sealed and plugged into the inside of the plug hole 11, thereby effectively preventing the intrusion of water, dust and other impurities. Furthermore, a sealant is filled between the annular protrusion 311 and the connecting line 21 to achieve the above-mentioned sealed plug-in. Furthermore, a limiting portion 111 is provided at the upper end of the plug hole 11. When the annular protrusion 311 is sealed and plugged into the plug hole 11, the upper end of the annular protrusion 311 abuts against the limiting portion 111, thereby ensuring the stability of the plug-in while further enhancing the sealing of the plug-in structure. By filling the annular protrusion 311 with glue and sealingly plugging the annular protrusion 311 with the sealing cover 1, the magnetic head 2 is completely isolated from the inside of the device. The overall structure is simple and easy to install. At the same time, the sealant is only filled between the annular protrusion 311 and the connecting line 21. Therefore, when the magnetic head 2 needs to be replaced, the sealing cover 1 can be removed, and the magnetic head 2 and the bracket 3 can be taken out and replaced. The sealing cover 1 can be repeatedly plugged in and used, which improves maintenance efficiency and saves costs.

[0041] Further, such as Figure 2 As shown, the upper edges of the sealing cover 1 and the insertion hole 11 are both provided with guide grooves 12 for guiding the FPC cable.

[0042] Preferably, the material of the sealing cover 1 includes but is not limited to elastic polymer materials such as TPU, silicone, rubber, etc., and the above-mentioned plug-in methods are all interference plug-ins to achieve a good sealing effect.

[0043] like Figure 3 As shown, elastic connectors 22 are disposed on both sides of the magnetic head 2 , first support plates 312 are disposed on both sides of the lower end of the top cover 31 , and the elastic connectors 22 are connected to the first support plates 312 .

[0044] In a specific embodiment, a positioning hole 221 is disposed at the tail end of the elastic connector 22 , and a positioning post 3121 is disposed on the first support plate 312 . When the magnetic head 2 is mounted on the bracket 3 , the positioning hole 221 is sleeved on the positioning post 3121 .

[0045] refer to Figure 4 and Figure 5The bracket 3 also includes a second support plate 313, which is located between the magnetic head 2 and the first support plate 312, and the first support plate 312 and the second support plate 313 are respectively located on the front and rear sides of the elastic connector 22. Specifically, the first support plate 312 is arranged on the rear side of the elastic connector 22, and the second support plate 313 is arranged on the front side of the elastic connector 22. When the magnetic head assembly is installed in the mounting slot 102, the second support plate 313 abuts against the inner wall of the housing 100, providing additional support for the bracket 3, enhancing the structural strength and stability of the entire bracket 3, and at the same time, the second support plate 313 further stabilizes the elastic connector 22, reduces the component wear and fatigue caused by frequent use, and improves the overall durability and performance of the device. Through the above structure, the stability of the device when swiping the card is significantly improved. In addition, the second support plate 313 also serves to locate the position of the magnetic head 2 to avoid the magnetic head 2 from being unable to read and write in the correct position due to left-right asymmetry during production.

[0046] In summary, the utility model provides a financial transaction device with simple structure, convenient installation, easy maintenance, and significant waterproof and dustproof effects.

[0047] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
