Abstract
Description
Technical Field
[0001] This utility model belongs to the field of terminal-related technology, specifically, it relates to a waterproof structure for a card slot and a terminal. Background Technology
[0002] Currently, most POS machines and other similar terminal devices on the market do not have dedicated waterproof designs for their IC card slots. In situations such as water spray tests or accidental water splashes, moisture can easily seep into the card slot through the card insertion point. Once moisture intrudes, it will not only directly affect the normal operation of the IC card slot, but will also further penetrate into more critical areas of the machine, such as the motherboard area and / or other vital functional component areas.
[0003] The motherboard, as the "brain" of the device, integrates numerous electronic components and circuit connections, making it extremely sensitive to moisture. Even trace amounts of moisture can cause short circuits, corrosion, or component damage, ultimately leading to functional failure of the entire device. Similarly, other functional components such as sensors and display driver modules cannot withstand moisture exposure; otherwise, performance degradation or complete failure will occur. Therefore, improvements are necessary. Utility Model Content

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0023] One embodiment of this application provides a waterproof structure for a card slot, such as... Figures 1-4 As shown, the waterproof structure is connected to the card slot of the terminal. The terminal is existing technology, such as a POS machine. The waterproof structure includes: a card holder connection unit 2 connected to the card slot 11 of the terminal body 1, and an IC card holder 3 connected inside the card holder connection unit 2. The structures of the terminal body 1 and the IC card holder 3 are existing technologies and will not be described in detail here.
[0024] Specifically, such as Figures 2-4 As shown, the card holder connection unit 2 includes a main housing 21 connected to the card slot 11 and a secondary housing 22 connected to the main housing 21. A mounting cavity for mounting an IC card holder 3 is formed between the main housing 21 and the secondary housing 22. The IC card holder 3 is disposed in the mounting cavity. The mounting cavity communicates with the card slot 11. The card slot of the IC card holder 3 corresponds to the card slot 11, so that the object to be identified can cooperate with the IC card holder 3 through the card slot 11 to realize the corresponding operation.
[0025] The main housing 21 has a connecting protrusion 23 that connects to the card slot 11. The outer surface of the connecting protrusion 23 is adapted to the card slot 11. The main housing 21 is connected to the card slot 11 through the connecting protrusion 23. The connecting protrusion 23 has a clearance channel 24 that extends through to the mounting cavity. The clearance channel 24 is used for the passage of the object to be identified, so that the object to be identified is connected to the IC card holder 3 located in the mounting cavity.
[0026] In one embodiment, such as Figure 2 and Figure 4As shown, it also includes a connecting plate 4, an IC card holder 3 connected to the connecting plate 4, and the connecting plate 4 connected to the sub-housing 22. The main housing 21 has an annular connecting boss 211 that abuts against the connecting plate 4. After the main housing 21 and the sub-housing 22 are connected, the annular connecting boss 211 abuts against the corresponding part of the connecting plate 4. The IC card holder 3 is located inside the annular connecting boss 211. The mounting cavity for installing the IC card holder 3 is relatively independent, separating the moisture entering from the card slot 11 and preventing it from entering the terminal body 1.
[0027] In one embodiment, such as Figure 2 and Figure 4 As shown, it also includes a first waterproof seal 5. The annular connecting boss 211 and the corresponding part of the connecting plate 4 are provided with the first waterproof seal 5 to further enhance the sealing performance.
[0028] In one embodiment, such as Figures 3-4 As shown, it also includes a second waterproof seal 6, which is sleeved on the connecting protrusion 23. The second waterproof seal 6 is located between the end face of the main housing 21 and the inner side of the insertion slot 11 to prevent moisture from entering the terminal body 1 from the gap between the main housing 21 and the terminal body 1.
[0029] In one embodiment, such as Figure 1 and Figures 3-4 As shown, it also includes a connector 7, through which the card holder connecting unit 2 is detachably connected to the terminal body 1; the connector 7 includes a connector body 71, with protruding clips 72 extending from the inner sides of the connector body 71 respectively; the end face of the main housing 21 of the card holder connecting unit 2 has a groove 73 that mates with the corresponding protruding clip 72; the protruding clip 72 passes through the first clearance hole 74 on the terminal body 1 and connects with the corresponding groove 73, and is then connected by fasteners, so that the card holder connecting unit 2 is detachably connected to the terminal body 1; during installation, the main housing 21 is connected to the card slot 11 of the terminal body 1 through the connecting protrusion 23, the main housing 21 is located inside the terminal body 1, and then the protruding clip 72 of the connector 7 passes through... The first clearance hole 74 on the terminal body 1 is connected to the corresponding groove 73. At this time, the connector body 71 is located outside the terminal body 1. Then, the fastener passes through the bottom of the groove 73 and is connected to the protruding card 72 to fix the main shell 21 to the terminal body 1. The connector 7 is provided with a second clearance hole 75, which cooperates with the connecting protrusion 23. The clearance channel 24 in the connecting protrusion 23 serves as the card insertion channel. The card insertion port is designed as an independent installation unit. The inside is sealed with the main shell by a sealing element, with no water leakage points. A complete sealed cavity is formed between the card insertion port and the IC card holder, which completely limits the possibility of water entering the terminal interior, thus achieving a true waterproof function.
[0030] In one embodiment, such as Figure 4 As shown, the inner edge of the second clearance hole 75 forms a limiting boss 76. When the connector 7 is engaged with the main housing 21, the connector 7 engages with the connecting protrusion 23 through the second clearance hole 75. The outer surface of the limiting boss 76 engages with the insertion slot 11 of the terminal body 1, further enhancing the reliability of the connection.
[0031] In one embodiment, such as Figures 3-4 As shown, it also includes a third waterproof seal 8, which is located between the connector 7 and the terminal body 1 to prevent moisture from entering the terminal body 1 from the gap between the main housing 21 and the terminal body 1.
[0032] One embodiment of this application provides a terminal that includes a waterproof structure with a card slot as described above.
[0033] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application.
