The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices and methods consistent with some aspects of the utility model as detailed in the attached claims.

[0046] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0047] It should be understood that in the present utility model, "electrical connection" can be understood as the physical contact and electrical conduction of components; it can also be understood as the form in which different components in the circuit structure are connected through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to a connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship, that is, A is connected to B or A is connected to B, which can mean that there is a fastening component (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0048] Unless otherwise defined, all technical terms used in the embodiments of the present invention have the same meanings as commonly understood by those skilled in the art.

[0049] In the related art, terminal boxes need to be arranged inside and outside the refrigerator for circuit connection. For example, they can be used to connect electrical devices such as lighting, temperature sensors, and fans inside the refrigerator.

[0050] The terminal box is usually pre-installed inside the refrigerator liner, attached to the inner side of the enclosure of the refrigerator liner, and uses the opening on the enclosure to achieve circuit connection with electrical devices inside or outside the refrigerator.

[0051] However, the terminal box is only attached to the inner side of the enclosure, lacks a force-bearing structure, and the assembly preload is insufficient; the terminal box also has poor structural accuracy and insufficient deformation resistance, which results in the terminal box and the inner side of the enclosure not fitting tightly together, resulting in an assembly gap between the two. The interior of the box liner also needs to be filled with foam. During the foaming process, the foaming material may flow into the terminal box along these gaps, blocking the terminal box and affecting the normal circuit connection of the terminal box.

[0052] Therefore, the utility model provides a terminal box assembly, in which a box cover is against the outer side surface of the enclosure, applying an outward pre-tightening force to the box body, so that the first outer edge of the box body is sealed with the inner side surface of the enclosure, thereby avoiding the formation of a gap between the box body and the enclosure, preventing the foaming material from entering the box body, ensuring the cleanliness of the box body, and achieving normal circuit connection.

[0053] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0054] On the one hand, combined with Figure 1 , Figure 2 and Figure 6As shown, this embodiment provides a terminal box assembly 100 , which is connected to a surrounding plate 300 of a box liner 200 , and a avoidance hole 3001 is provided on the surrounding plate 300 .

[0055] The terminal box assembly 100 includes a box body 1 and a box cover 2 , which are respectively located on two sides of the enclosure 300 ; the box body 1 includes a first clamping structure 11 and a first outer edge 12 , and the box cover 2 includes a second clamping structure 21 .

[0056] The first clamping structure 11 and the second clamping structure 21 are clamped and connected through the avoidance hole 3001, and the box cover 2 is in abutment with the outer side surface of the enclosure 300 around the avoidance hole 3001, and a pre-tightening force is applied to the box body 1 through the first clamping structure 11 and the second clamping structure 21, so that the first outer edge 12 is sealed and fit with the inner side surface of the enclosure 300 around the avoidance hole 3001.

[0057] The terminal box assembly 100 of this embodiment comprises a box body 1 and a box cover 2, and the box body 1 and the box cover 2 are respectively arranged on the inner and outer sides of the enclosure 300 of the inner tank 200 of the refrigerator, and the box body 1 and the box cover 2 are connected by clamping through the avoidance hole 3001 of the enclosure 300 using the first clamping structure 11 and the second clamping structure 21, and the box cover 2 is against the outer side surface of the enclosure 300, and an outward pre-tightening force is applied to the box body 1 through the first clamping structure 11 and the second clamping structure 21, so that the first outer edge 12 of the box body 1 is sealed and fitted with the inner side surface of the enclosure 300, thereby avoiding the formation of a gap between the box body 1 and the enclosure 300, preventing the foaming material from entering the box body 1, ensuring the cleanliness of the box body 1, and realizing normal circuit connection.

[0058] In some possible implementations, reference Figure 1 As shown, the box cover 2 further includes a second outer edge 22 , and the box cover 2 abuts against the outer side surface of the surrounding plate 300 around the avoidance hole 3001 by using the second outer edge 22 .

[0059] For other possible implementations, see Figure 2 As shown, the terminal box assembly 100 also includes a wiring terminal 3, which is located on the side of the box body 1 facing away from the box cover 2 and is plugged into the box body 1. One end of the wiring terminal 3 extends into the box body 1, so that the avoidance hole 3001 on the enclosure 300 can be used for circuit connection. The other end of the wiring terminal 3 is located outside the box body 1 and can be connected to a wire.

[0060] Combination Figure 1 As shown, in some embodiments, the number of the first clamping structure 11 and the number of the second clamping structure 21 are respectively two.

[0061] The two first clamping structures 11 are located at two opposite sides of the box body 1 , the two second clamping structures 21 are located at two corresponding opposite sides of the box cover 2 , and the two second clamping structures 21 are both located between the two first clamping structures 11 .

[0062] Through the above arrangement, the number of the first clamping structure 11 and the second clamping structure 21 are two respectively, and they are respectively arranged on the opposite sides of the box body 1 or the box cover 2. The pre-tightening force can be applied to the opposite sides of the box body 1, and the force balance of the box body 1 is more conducive to making the first outer edge 12 of the box body 1 and the inner side surface of the enclosure 300 sealed, thereby avoiding the occurrence of a gap between the box body 1 and the enclosure 300.

[0063] Combination Figure 3 As shown, in some embodiments, each first clamping structure 11 includes a first clamping portion 111 . Each second clamping structure 21 includes an extension arm 211 and a second clamping portion 212 .

[0064] The first end 2111 of the extension arm 211 is connected to the box cover 2 , and the second end 2112 of the extension arm 211 extends into the box body 1 ; the first clamping portion 111 is located on the second end 2112 of the extension arm 211 and is clamped and connected to the second clamping portion 212 .

[0065] Through the above arrangement, the second clamping structure 21 includes an extension arm 211 and a second clamping portion 212, and the second end 2112 of the extension arm 211 extends into the box body 1, and the second clamping portion 212 is arranged on the second end 2112 of the extension arm 211, so that the first clamping structure 11 in the box body 1 can only have a first clamping portion 111 arranged on the inner wall, so as to realize the clamping connection between the first clamping structure 11 and the second clamping structure 21, without arranging redundant structures in the box body 1, and thus freeing up space in the box body 1, which is beneficial to the installation and arrangement of the terminal block 3.

[0066] Exemplarily, the first clamping portion 111 is located on the inner wall of the box body 1 .

[0067] In some embodiments, one of the first clamping portion 111 and the second clamping portion 212 is a clamping slot, and the other is a buckle. Exemplarily, the first clamping portion 111 is a buckle, and the second clamping portion 212 is a clamping slot; or, the first clamping portion 111 is a clamping slot, and the second clamping portion 212 is a buckle.

[0068] Combination Figure 4 As shown, in some embodiments, the box cover 2 further includes a quick-release pull rod 23 .

[0069] The quick-release pull rod 23 is located inside the box cover 2 and is respectively connected to the two extension arms 211 of the two second clamping structures 21 .

[0070] A hollow portion 24 is provided on the side of the box cover 2 facing away from the box body 1 , and the hollow portion 24 corresponds to the position of the quick-release pull rod 23 .

[0071] When the quick release rod 23 is pulled through the hollow portion 24 , the quick release rod 23 can drive the second end 2112 of each extension arm 211 and the second clamping portion 212 away from the corresponding first clamping portion 111 to unlock the second clamping portion 212 from the corresponding first clamping portion 111 .

[0072] In this embodiment, the connection terminals 3 are arranged in the box body 1 of the terminal box assembly 100, and the circuit connection needs to be made from the outside of the enclosure 300 through the avoidance hole 3001, and the box cover 2 will inevitably cause obstacles. Therefore, a quick release pull rod 23 is provided on the box cover 2 of this embodiment, and the quick release pull rod 23 can be used to quickly unlock the second clamping portion 212 and the first clamping portion 111, so that the box cover 2 can be quickly removed.

[0073] Illustratively, the operator uses his hand or a tool to contact the quick-release rod 23 through the hollow portion 24 and pry it outward, and the quick-release rod 23 is connected to the extension arm 211. Since the extension arm 211 is supported by a plastic material and has deformation capability, it will deform under the torque traction of the quick-release rod 23, thereby driving the second clamping portion 212 away from the first clamping portion 111, thereby achieving separation and unlocking of the two.

[0074] In this embodiment, the main function of the box cover 2 is to provide assembly pre-tightening force for the box body 1 during the foaming process of the box liner 200, and once the foaming process of the box body is completed, the space on the inner side of the enclosure 300 is filled with foaming material. After the foaming is cured, the box body 1 can be pressed against the inner side of the enclosure 300 by the foaming material, and the box cover 2 will no longer work. At this time, the box cover 2 can be removed using the quick-release pull rod 23. The removed box cover 2 can be transported back to the upstream of the product production line and installed on the enclosure 300 of another box liner 200 to be processed by the foaming process, and be snap-connected with another box body 1 on the inner side of the enclosure 300, so that the box cover 2 can be used as a turnover tooling during the installation process of the terminal box assembly 100, which is conducive to reducing the number of structural parts of refrigerator products, reducing the production cost of products, and improving resource utilization efficiency.

[0075] Combination Figure 4 As shown, in some embodiments, the quick release rod 23 is connected to the side of the extension arm 211 facing away from the first clamping portion 111 , and an oblique tie bar 25 is further provided between the second end 2112 of the extension arm 211 and the quick release rod 23 .

[0076] In this embodiment, the quick-release rod 23 is arranged on the side of the extension arm 211 facing away from the first clamping portion 111, and an oblique tie rod 25 is also provided between the extension arm 211 and the quick-release rod 23. Therefore, when the quick-release rod 23 is pulled outward, the quick-release rod 23 can drive the extension arm 211 to deform toward the side facing away from the first clamping portion 111, and drive the second clamping portion 212 away from the first clamping portion 111, thereby realizing the separation and unlocking of the two. The provision of the oblique tie rod 25 can optimize the force direction and connection strength between the quick-release rod 23 and the extension arm 211.

[0077] Combination Figure 5 As shown, in some embodiments, the box cover 2 further includes a frame structure 26 and two flap structures 27 .

[0078] Each flap structure 27 corresponds to a second clamping structure 21 , and one side of each flap structure 27 is connected to the frame structure 26 , and the other side extends into the box cover 2 .

[0079] The side of the flap structure 27 facing the box body 1 is connected to the first end 2111 of the extension arm 211 of the corresponding second clamping structure 21 .

[0080] In order to further improve the quick-release effect of the box cover 2, two flap structures 27 are arranged on the frame structure 26 of the box cover 2. The flap structure 27 is located inside the box cover 2 and is connected to the frame structure 26. The extension arm 211 is connected to the flap structure 27. When the quick-release pull rod 23 drives the extension arm 211 to deform, the flap structure 27 deforms accordingly, thereby utilizing the deformation of the extension arm 211 and the flap structure 27 to drive the second clamping portion 212 away from the first clamping portion 111, thereby realizing the separation and unlocking of the two.

[0081] Combination Figure 5 As shown, in some embodiments, a material-reducing groove 271 is provided on one side of the flap structure 27 close to the frame structure 26 , and the position of the material-reducing groove 271 is aligned with the position of the first end 2111 of the extension arm 211 .

[0082] Through the above arrangement, the flap structure 27 utilizes the material-reducing groove 271 thereon to improve its own deformation ability, which is beneficial to improving the quick-disassembly effect of the box cover 2.

[0083] Combination Figure 5 As shown, in some embodiments, two adjacent corners of the frame structure 26 are provided with chamfer structures 261. The chamfer structures 261 arranged on two adjacent corners of the frame structure 26 of the box cover 2 can be used as a foolproof design during the installation process of the box cover 2, which is conducive to improving the efficiency of the installation of the box cover 2.

[0084] Exemplarily, chamfer structures 261 are provided on two top corners of the frame structure 26 of the box cover 2 .

[0085] Combination Figure 2 and Figure 6 As shown, in some embodiments, the box body 1 is provided with at least one first positioning structure 13, and the box cover 2 is provided with at least one second positioning structure 28, and at least the first positioning structure 13 and at least one second positioning structure 28 are connected in a limiting manner through the avoidance hole 3001.

[0086] Through the above arrangement, on the one hand, the first positioning structure 13 and the second positioning structure 28 can realize the connection positioning between the box body 1 and the box cover 2, and on the other hand, the first positioning structure 13 and the second positioning structure 28 can also be used for positioning between the box body 1 or the box cover 2 and the avoidance hole 3001 of the enclosure 300.

[0087] On the other hand, combined Figure 7 As shown, this embodiment provides a refrigerator, which includes a box liner 200 , and a terminal box assembly 100 of the utility model is provided on a surrounding plate 300 of the box liner 200 .

[0088] The refrigerator of this embodiment adopts the terminal box assembly 100 of the present utility model, and has all the beneficial technical effects of all the embodiments herein.

[0089] In some embodiments, reference Figure 7 As shown, the refrigerator further includes a fan 400, an inner panel 301 is provided on the side of the box liner 200 facing the inside of the refrigerator, and an outer panel 302 is provided on the side of the box liner 200 facing the outside of the refrigerator.
