The first direction of the housing assembly 1 can refer to Figure 1In the front-to-back direction, the card slot 13 is suitable for inserting a card. Specifically, the card is inserted between the upper shell 11 and the lower shell 12 through the open end of the card slot 13. In some specific embodiments, the card can be a bank card or the like.
[0031] The upper shell 11 is provided with a first prefabricated hole 111, and the lower shell 12 is provided with a second prefabricated hole 121. The first prefabricated hole 111 and the second prefabricated hole 121 are both connected to the card insertion slot 13. The first prefabricated hole 111 and the second prefabricated hole 121 are both constructed as through holes. In some specific embodiments, along the first direction of the shell assembly 1, the first prefabricated hole 111 can be set on the upper end wall of the upper shell 11, and the second prefabricated hole 121 can be set on the lower end wall of the lower shell 12. In addition, the upper shell 11 is affixed with a first waterproof sticker 112 opposite to the first preformed hole 111, and the lower shell 12 is affixed with a second waterproof sticker 122 opposite to the second preformed hole 121. Specifically, the first waterproof sticker 112 is affixed to the upper end wall of the upper shell 11, and the second waterproof sticker 122 is affixed to the lower end wall of the lower shell 12. When liquid enters the card slot 13, the first waterproof sticker 112 is used to prevent the liquid from entering the POS (Point of sales) machine through the first preformed hole 111, and the second waterproof sticker 122 is used to prevent the liquid from entering the POS machine through the second preformed hole 121.
[0032] It should be noted that the first prefabricated hole 111 is completely covered by the first waterproof sticker 112 , and the second prefabricated hole 121 is completely covered by the second waterproof sticker 122 .
[0033] In some specific embodiments, the first waterproof sticker 112 and the second waterproof sticker 122 may both be Mylar stickers, but the present application is not limited thereto. The first waterproof sticker 112 and the second waterproof sticker 122 may also be 3M stickers or the like.
[0034] Furthermore, a sealing colloid is disposed between the upper shell 11 and the lower shell 12. Specifically, a sealing colloid is disposed at the connection between the upper shell 11 and the lower shell 12. That is, along the second direction of the shell assembly 1, the second direction of the shell assembly 1 can refer to Figure 1 In the left and right directions, a sealing colloid is provided at the connection between the upper shell 11 and the lower shell 12 opposite to the left side wall of the card insertion slot 13, a sealing colloid is provided at the connection between the upper shell 11 and the lower shell 12 opposite to the right side wall of the card insertion slot 13, and a sealing colloid is provided at the connection between the upper shell 11 and the lower shell 12 opposite to the bottom wall of the card insertion slot 13. The sealing colloid is used to prevent the liquid in the card insertion slot 13 from entering the POS machine through the gap between the upper shell 11 and the lower shell 12.
[0035] In some specific embodiments, the sealing colloid may be epoxy resin, but the present application is not limited thereto, and the sealing colloid may also be silicone sealant or the like.
[0036] The card reader terminal group 2 is arranged in the second prefabricated hole 121 , extends into the card insertion slot 13 and is suitable for abutting and electrically connecting with the card, and is communicatively connected with the controller, and the controller reads the data of the card through the card reader terminal group 2 .
[0037] Specifically, the card reading terminal group 2 includes multiple card reading terminals, and the controller reads the data of the card through the multiple card reading terminals. The card reading terminals are suitable for bending and deformation. When the card is inserted into the card slot 13, the card and the card reading terminals are stopped and electrically connected, and the card drives the card reading terminals to bend and deform to move in a direction away from the upper shell 11. The second prefabricated hole 121 is used to avoid the card reading terminal, thereby preventing the card reading terminal from interfering with the lower shell 12 and causing the card to be unable to be inserted into the card slot 13.
[0038] Thus, by using the first waterproof sticker 112 to seal the first prefabricated hole 111, using the second waterproof sticker 122 to seal the second prefabricated hole 121, and using the sealing colloid to seal the gap between the upper shell 11 and the lower shell 12. Compared with the prior art, the liquid in the card slot 13 cannot flow into the POS machine through the first prefabricated hole 111, the second prefabricated hole 121 and the gap between the upper shell 11 and the lower shell 12, which can prevent the POS machine from being damaged by the liquid and failing to work properly, thereby improving the waterproof performance of the waterproof card holder 100.

The first positioning structure 113 and the second positioning structure 123 are positioned and matched, and a sealing colloid is arranged between the first positioning structure 113 and the second positioning structure 123.
[0040] Specifically, when assembling the upper shell 11 and the lower shell 12, the first positioning structure 113 and the second positioning structure 123 are used for positioning and matching, so as to reduce the difficulty of assembling the upper shell 11 and the lower shell 12, and prevent the upper shell 11 and the lower shell 12 from being misaligned after being assembled, which would require reassembling the upper shell 11 and the lower shell 12.
[0041] Furthermore, before assembling the upper shell 11 and the lower shell 12, one of the first positioning structure 113 and the second positioning structure 123 is provided with a liquid sealing colloid, and then the upper shell 11 and the lower shell 12 are assembled. After the sealing colloid is cured, the sealing colloid bonds the first positioning structure 113 and the second positioning structure 123 together, thereby improving the connection reliability between the upper shell 11 and the lower shell 12, and preventing misalignment between the upper shell 11 and the lower shell 12.

[0043] In some specific embodiments, the first positioning structure 113 is constructed as a positioning protrusion, and the second positioning structure 123 is constructed as a glue injection groove. Before assembling the upper shell 11 and the lower shell 12, the glue injection groove is filled with liquid sealing colloid, and then the upper shell 11 and the lower shell 12 are assembled, and the positioning protrusion extends into the glue injection groove. After the sealing colloid solidifies, the sealing colloid fixes the positioning protrusion in the glue injection groove, thereby achieving the technical effect of positioning and matching the upper shell 11 and the lower shell 12, and achieving the technical effect of using the sealing colloid to seal the gap between the upper shell 11 and the lower shell 12.

After the upper shell 11 and the lower shell 12 are assembled, the lower end of the grounding plate 4 passes through the upper shell 11 and the lower shell 12 in sequence and is fixedly connected and electrically connected to the circuit board 3. Compared with fixing the shell assembly 1 to the circuit board 3 by threaded fasteners, such a setting can not only use the grounding plate 4 to realize the grounding function of the circuit board 3, but also use the grounding plate 4 to fix the shell assembly 1 to the circuit board 3, which can reduce the parts of the waterproof card holder 100, thereby reducing the manufacturing cost of the waterproof card holder 100, and can simplify the assembly process of the waterproof card holder 100, thereby improving the assembly efficiency of the waterproof card holder 100.

[0058] In some specific embodiments, the second guide structure 126 can be constructed as a guiding slope, and the second guide structure 126 is arranged around the top wall of the second connecting groove 124. When the grounding plate 4 extends into the second connecting groove 124, the second guide structure 126 can guide the grounding plate 4 from multiple directions, thereby further reducing the difficulty of the grounding plate 4 entering the second connecting groove 124, and further improving the assembly efficiency of the connection structure of the components.
[0059] Reference Fig.15 and Fig.16 In some embodiments of the present application, a first snap-fitting structure 44 is provided on the side wall of the grounding plate 4, and a second snap-fitting structure 127 is provided on the inner wall of the first connecting groove 114 or the inner wall of the second connecting groove 124, and the first snap-fitting structure 44 is snap-fitted with the second snap-fitting structure 127.
[0060] In some specific embodiments, along the second direction of the shell assembly 1, the right side wall of the grounding plate 4 is provided with a first clip structure 44, and the first connecting groove 114 is provided with a second clip structure 127. When the grounding plate 4 passes through the first connecting groove 114 and the second connecting groove 124 in sequence and extends into the connecting hole 31, the first clip structure 44 is clipped into cooperation with the second clip structure 127, thereby preventing the grounding plate 4 from detaching from the shell assembly 1 and causing the grounding plate 4 to be unable to be welded to the connecting hole 31, thereby improving the assembly efficiency of the connecting structure of the components.
[0061] In some specific embodiments, one of the first clamping structure 44 and the second clamping structure 127 can be constructed as a clamping protrusion, and the other of the first clamping structure 44 and the second clamping structure 127 can be constructed as a clamping recess, and the clamping protrusion extends into the clamping recess and engages with the clamping recess.
[0062] In some embodiments of the present application, there are multiple first clip structures 44 and multiple second clip structures 127, and the multiple first clip structures 44 and multiple second clip structures 127 are arranged spaced apart along the circumferential direction of the grounding plate 4, and the multiple first clip structures 44 and multiple second clip structures 127 are arranged one by one.
[0063] The multiple first clip-on structures 44 are clipped together with the corresponding second clip-on structures 127. When one of the multiple first clip-on structures 44 and / or one of the multiple second clip-on structures 127 is damaged, the remaining first clip-on structures 44 among the multiple first clip-on structures 44 and the remaining second clip-on structures 127 among the multiple second clip-on structures 127 are clipped together, thereby preventing the grounding plate 4 from detaching from the shell assembly 1 and causing the grounding plate 4 to be unable to be welded to the connecting hole 31, thereby improving the connection reliability between the grounding plate 4 and the shell assembly 1.
[0064] Reference Fig.11 In some embodiments of the present application, a limiting portion 125 is provided on the end wall of the lower shell 12 close to the circuit board 3. Along the height direction of the shell assembly 1, the limiting portion 125 is provided on the lower end wall of the shell, and the circuit board 3 is provided with a limiting hole 32. The limiting portion 125 and the limiting hole 32 are matched for limiting.
[0065] Specifically, when the shell assembly 1 is installed to the circuit board 3, the limiting portion 125 extends into the limiting hole 32 to cooperate with the limiting hole 32, thereby preventing the shell assembly from deviating from the preset installation position and preventing the first connecting groove 114 and the second connecting groove 124 from being unable to be arranged relative to the connecting hole 31, thereby reducing the difficulty of installing the shell assembly 1 to the circuit board 3 and improving the assembly efficiency of the waterproof card holder 100.
[0066] Furthermore, there are multiple limiting portions 125 and multiple limiting holes 32, and the multiple limiting portions 125 and the multiple limiting holes 32 are spaced apart along the radial direction of the shell assembly 1. The multiple limiting portions 125 and the multiple limiting holes 32 are arranged in a one-to-one correspondence, and the multiple limiting portions 125 and the multiple limiting holes 32 are limited and matched, thereby further preventing the shell assembly from deviating from the preset installation position.
[0067] In some embodiments of the present application, along the height direction of the shell component 1, in order to enable cards of various different thicknesses to be inserted into the card insertion slot 13 and to enable the waterproof card holder 100 to be installed in a small product, it is necessary to reduce the thickness of the shell component 1 and increase the height of the card insertion slot 13. The lower shell 12 is provided with a card reading terminal group 2, and the wall thickness of the bottom wall of the lower shell 12 is difficult to reduce. Therefore, it is necessary to reduce the wall thickness of the top wall of the upper shell 11. When the wall thickness of the top wall of the upper shell 11 is less than the preset minimum thickness value, the top wall of the upper shell 11 is difficult to injection mold, and the upper shell 11 needs to be split into two parts.
[0068] In some specific embodiments, the preset minimum thickness value may be 0.8 mm. It should be noted that the preset minimum thickness values of different plastic materials are different.
[0069] Reference Figure 1 , Figure 3 ,and Fig.10 The upper shell 11 includes a connecting frame 115 and a cover plate 116. The top wall of the cover plate 116 is provided with a first preformed hole 111. The cover plate 116 and the connecting frame 115 are connected and matched and constructed as an integrally formed part, and the connecting frame 115 surrounds the outer side of the cover plate 116. Specifically, the connecting frame 115 is an injection molded part, and the cover plate 116 is a hardware part. The first preformed hole 111 is positioned and matched with the positioning column in the injection mold to install the cover plate 116 in the injection mold. The connecting frame 115 and the cover plate 116 are injection molded into the upper shell 11 by encapsulation.
[0070] By constructing the connecting frame 115 and the cover plate 116 as an integrally formed part, the connecting gap between the connecting frame 115 and the cover plate 116 can be eliminated, and the liquid in the card slot 13 can be prevented from entering the POS machine through the gap between the connecting frame 115 and the cover plate 116, thereby improving the waterproof performance of the waterproof card holder 100.
[0071] Furthermore, the card reading terminal group 2 and the lower shell 12 are constructed as an integrally formed part. By constructing the card reading terminal group 2 and the lower shell 12 as an integrally formed part, the connection gap between the card reading terminal group 2 and the lower shell 12 can be eliminated, and the liquid in the card insertion slot 13 can be prevented from entering the POS machine through the gap between the card reading terminal group 2 and the lower shell 12, thereby further improving the waterproof performance of the waterproof card holder 100.
[0072] Reference Figure 8 and Fig. 9 In some embodiments of the present application, there are multiple first preformed holes 111 and multiple second preformed holes 121, and the multiple first preformed holes 111 and the multiple second preformed holes 121 are spaced apart in the radial direction of the shell assembly 1. The multiple first preformed holes 111 are used to position the cover plate 116 in the injection mold. The multiple second preformed holes 121 are arranged in a one-to-one correspondence with the multiple card reading terminals, and the spacing distance between the inner circumferential wall of the second preformed hole 121 and the card reading terminal is small. The card reading terminal is suitable for abutting with the inner circumferential wall of the second preformed hole 121, so as to prevent the card reading terminal from being bent and deformed to a large extent by external force as much as possible, and to avoid the card reading terminal deviating from the preset position, resulting in the controller being unable to read the card data.
[0073] Moreover, along the height direction of the shell assembly 1, the projection area of the first waterproof sticker 112 is larger than the total projection area of the multiple first prefabricated holes 111, and the projection area of the second waterproof sticker 122 is larger than the total projection area of the multiple second prefabricated holes 121. That is to say, the multiple first prefabricated holes 111 are all completely covered by the first waterproof sticker 112, and the multiple second prefabricated holes 121 are all completely covered by the second waterproof sticker 122, thereby preventing the liquid in the card slot 13 from entering the POS machine through the multiple first prefabricated holes 111 and the multiple second prefabricated holes 121, thereby further improving the waterproof performance of the waterproof card holder 100.
[0074] Reference Figure 3 , Figure 8 and Fig.10 In some embodiments of the present application, the waterproof card holder 100 may further include: a detection switch 5 and a switch spring 6, both of which are arranged in the upper shell 11 or the lower shell 12. In some specific embodiments, the detection switch 5 and the switch spring 6 are both arranged in the lower shell 12, and the switch spring 6 has a trigger portion 61 suitable for bending and deforming and extending into the card insertion slot 13. Along the height direction of the shell assembly 1, the trigger portion 61 is located above the detection switch 5, one end of the trigger portion 61 is arranged opposite to the detection switch 5 and is suitable for abutting against the detection switch 5, and the other end of the trigger portion 61 is suitable for abutting against the card. Specifically, the lower end surface of the trigger portion 61 is arranged opposite to the detection switch 5 and is suitable for abutting against the detection switch 5, and the upper end surface of the trigger portion 61 is suitable for abutting against the card.
[0075] The card is used to drive the trigger part 61 to move close to the detection switch 5. The detection switch 5 is connected to the controller for communication. When the trigger part 61 and the detection switch 5 are stopped, the controller is used to read the data of the card according to the start signal of the detection switch 5.
[0076] Specifically, when the card is inserted into the card slot 13, the card and the trigger part 61 stop and drive the trigger part 61 to bend and deform toward the detection switch 5, so that the trigger part 61 and the detection switch 5 stop. When the trigger part 61 and the detection switch 5 stop, the detection switch 5 generates a start signal, and the controller reads the card data through the card reading terminal group 2 according to the start signal of the detection switch 5. Compared with the controller continuously starting up and reading the card data or waiting to read the card data, such a setting can reduce the energy consumption of the waterproof card holder 100, thereby improving the energy saving performance of the waterproof card holder 100.
[0077] In some specific embodiments, the detection switch 5 may be a micro switch, but the present application is not limited thereto. The detection switch 5 may also be a piezoelectric switch or the like.
[0078] Reference Fig.10 and Fig.12 In some embodiments of the present application, the waterproof card holder 100 may also include: an anti-static sheet 7, the anti-static sheet 7 is arranged on the upper shell 11 or the lower shell 12, and the anti-static sheet 7 is located on the side of the open end of the card reading terminal group 2 close to the card insertion slot 13. In some specific embodiments, the anti-static sheet 7 is arranged on the lower shell 12, one end of the anti-static sheet 7 is grounded, and the other end of the anti-static sheet 7 is provided with a conducting part 71, which extends into the card insertion slot 13 and is suitable for abutting against the card.
[0079] Specifically, when the card is inserted into the card slot 13, the card abuts against the conductive part 71, which is used to conduct static electricity of the card, thereby preventing the card reading terminal group 2 from being interfered by static electricity and causing the controller to be unable to read the card data, thereby improving the working reliability of the waterproof card holder 100.
[0080] Furthermore, the circuit board 3 is provided with a grounding hole 33, and the circuit board 3 forms a grounding circuit, which is electrically connected to the grounding plate 4. The anti-static plate 7 is provided with a grounding portion 72 at one end away from the conductive portion 71. The grounding portion 72 passes through the lower shell 12 and extends into the grounding hole 33 and is electrically connected to the grounding circuit. In this way, the anti-static plate 7 does not need to be grounded separately, thereby reducing the manufacturing difficulty of the waterproof card holder 100.
[0081] Further, refer to Figure 3 and Figure 5 The antistatic sheet 7 and the lower shell 12 are constructed as an integrally formed part, thereby preventing the liquid in the card slot 13 from entering the POS machine through the gap between the antistatic sheet 7 and the lower shell 12 .
[0082] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
