[0035] like Figure 1 and Figure 2 As shown, the present application provides a payment terminal with an IC card slot waterproof structure, including a housing 100, wherein a main board 1 and an IC card assembly 2 electrically connected to each other through a connecting line 22 are arranged inside the housing 100, wherein the IC card assembly 2 is provided with an IC card slot 21, and further comprises a sealing cover 3, wherein the housing 100 is provided with a mounting groove 101, and the sealing cover 3 is buckled in the mounting groove 101 to form an isolation chamber, wherein the IC card assembly 2 is fixedly arranged inside the isolation chamber, and the main board 1 is located outside the isolation chamber.

[0036] In a specific embodiment, the housing 100 has an open opening at the bottom, and the IC card slot 21 is correspondingly disposed in the open opening. An upper guide plate 211 and a lower guide plate 212 are disposed at the entrance of the IC card slot 21. When in use, the IC card enters the IC card slot 21 from the open opening. Figure 2 As shown, the housing 100 is surrounded by a side surface 1011 to form a mounting groove 101. The IC card assembly 2 is fixedly installed in the mounting groove 101 by fasteners, and a sealing cover 3 is buckled on the top of the mounting groove 101. Figure 3 As shown in the schematic diagram of the sealing cover 3 structure from an upward angle, a positioning groove 35 is arranged around the outer periphery of the bottom of the sealing cover 3. When the sealing cover 3 is buckled, the positioning groove 35 is plugged into the side panel to form an isolation chamber. The main board 1 is located outside the isolation chamber to prevent water vapor, dust, and salt mist from entering the main board 1 from the open opening, thereby reducing the risk of oxidation and short circuit of the main board 1 and improving the overall safety and reliability of the payment terminal.

[0037] like Figure 2 and Figure 4 As shown, a connection line 22 is provided on one side of the IC card assembly 2, and an annular protrusion 23 is provided around the connection line 22. In a specific embodiment, the connection line 22 is an FPC cable, and the annular protrusion 23 is a long strip matching the FPC cable. After the FPC cable passes through the annular protrusion 23, glue is poured into the annular protrusion 23 to prevent water vapor, dust, and salt mist from entering the main board 1 from there. Corresponding to the annular protrusion 23, a plug hole 31 is provided on the side of the sealing cover 3 close to the IC card assembly 2, and a limiting portion is provided on the upper end of the plug hole 31. When the sealing cover 3 is buckled in the mounting groove 101, the annular protrusion 23 is sealed and plugged into the inside of the plug hole 31, and the upper end of the annular protrusion 23 abuts against the limiting portion on the upper end of the plug hole 31. The connection line 22 extends to the outside of the isolation chamber through the plug hole 31 and is electrically connected to the main board 1.

[0038] Furthermore, the material of the sealing cover 3 includes but is not limited to elastic 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.

The protrusion 32 is snap-into the snap-in groove 11, and the connecting wire 22 passes through the protrusion 32 and is electrically connected to the upper surface of the mainboard 1. By snapping the protrusion 32 with the snap-in groove 11, the mainboard 1 can be pre-installed, the tightness of the IC card assembly 2, the sealing cover 3 and the mainboard 1 is increased, and the stability of the internal structure is enhanced. Furthermore, a clearance groove 33 is provided on the side of the sealing cover 3 close to the mainboard 1. After the mainboard 1 and the sealing cover 3 are attached, the clearance groove 33 and the mainboard 1 form a cavity, which avoids contact with the components on the mainboard 1 while achieving a protective effect.

[0040] like Figure 3 As shown, the front end of the sealing cover 3 is provided with an extension portion 34, referring to Figure 4 and Figure 5 In a specific embodiment shown, the extension portion 34 fills the gap between the housing 100 and the IC card assembly 2 to prevent water vapor, dust, and salt mist from entering through the gap. At the same time, the extension portion 34 also forms a card insertion channel connecting the upper guide plate 211 and the open opening of the housing 100, so that the IC card can be accurately and smoothly inserted into the device, avoiding unnecessary collisions with internal structures such as the upper guide plate 211, thereby protecting the upper guide plate 211 from damage.

[0041] Further, such as Figure 4 and Figure 5 As shown, the extension portion 34 also includes two support columns 341, which are respectively arranged on both sides of the IC card slot 21 and abut against the lower PCB board of the IC card assembly 2 to enhance the stability of the IC card slot 21 and avoid deformation caused by external force that causes damage to the sealing effect, thereby improving the durability and reliability of the entire device.
