Description

Technical Field

[0001] The present invention belongs to the technical field of electrical appliances, and more specifically, relates to a terminal wiring board, a refrigerator, and a household appliance. Background Art

[0002] For the convenience of assembly, wiring harness terminals inside electrical appliances such as refrigerators are generally fixed using a wiring board. Different refrigerator configurations mean that different wiring harness terminals need to be used, and thus different wiring board sockets are required for mounting. To achieve the generalization of the wiring board as much as possible, multiple sockets with different sizes are usually opened on a wiring board to enable the mounting of various types of wiring harness terminals. The problem is that the size of such wiring boards is generally large, resulting in poor flatness of the sealing surface of the wiring board and poor cooperation with the box liner, which is prone to material leakage. In addition, a larger wiring board means that a larger mating punching hole needs to be opened on the box liner, resulting in poor stiffness at the punching position of the box liner. Moreover, usually, multiple sockets on the wiring board are not used simultaneously. A refrigerator load scheme generally only requires the use of one wiring board notch, which leads to the need for additional sealing work for the redundant wiring board sockets. Summary of the Invention

[0003] The purpose of the embodiments of the present invention is to provide a terminal wiring board, a refrigerator, and a household appliance to solve the technical problems in the prior art, such as excessive sockets on the wiring board causing the wiring board and the box liner to be easily deformed, the large size of the wiring board, and the need for sealing of the remaining jacks.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: to provide a terminal wiring board, including:

[0005] A base;

[0006] A first wiring piece, provided on the base, and the first wiring piece is provided with a first jack for fixing a first type of terminal; and

[0007] A second wiring piece, rotatably connected to the base, and the second wiring piece is provided with a second jack for fixing a second type of terminal;

[0008] The second wiring piece has a first position state and a second position state;

[0009] In the first position state, the second wiring piece is rotated to abut against the first wiring piece, at least part of the first jack and the second jack overlap, and the second wiring piece shields at least part of the periphery of the first jack. At this time, the second jack is used for inserting the second type of terminal;

[0010] The second position state is that the second plug-in piece is rotated to a yield position so that the first plug-in hole of the first plug-in piece is exposed. At this time, the first plug-in hole is used to plug in the first type of terminal.

[0011] In the above scheme, the terminal strip includes a base, a first plug piece and a second plug piece, and the first plug piece and the second plug piece are respectively provided with a first socket and a second socket. When the second type of terminal needs to be fixed, the second plug piece is rotated to be in contact with the first plug piece, the first socket is blocked, the second socket is exposed, and the second type of terminal is plugged and fixed in the second socket; when the first type of terminal needs to be fixed, the second plug piece is rotated to a yield position, the first socket is exposed, and the first type of terminal is plugged in the first socket. In this way, the terminal strip can carry two different types of terminals, but the occupied volume is small, the strip and the box are not easy to deform, and after using one of the sockets, the other remaining socket does not need to be sealed, and there is no need to design a sealing structure.

[0012] Optionally, the base is provided with a resting surface for the second plug-in piece to rest against when the second plug-in piece is rotated to the yield position.

[0013] By setting the docking surface, the second plug-in piece is stably maintained in the second position state, preventing the second plug-in piece from rotating in the opposite direction to block the first plug-in hole.

[0014] Optionally, the second plug-in piece is provided with a first clamping structure near the second plug-in hole for clamping to the inner wall of the first plug-in hole.

[0015] In the above scheme, by setting a first clamping structure on the second plug-in piece near the second socket, the second plug-in piece can be clamped with the first socket through the first clamping structure, and the second plug-in piece can be clamped on the first plug-in piece, so that the second type of terminal can be stably mounted on the second socket.

[0016] Optionally, the first snap-fit ​​structure includes a snap-fit ​​protrusion that is at least partially contoured to the first socket, the snap-fit ​​protrusion being formed by a protrusion on one side of the second plug-in piece facing the first plug-in piece, and an outer wall of the snap-fit ​​protrusion having an interference fit with an inner wall of the first socket.

[0017] In the above scheme, the outer wall of the clamping protrusion is interference-fitted with the inner wall of the first plug hole. When the second plug piece is fixed to the first plug piece, a slight external force is applied to the second plug piece to squeeze the clamping protrusion into the first plug hole. Under the action of the friction between the two, the first plug piece and the second plug piece are fixed to each other. In this way, there is no need to set up structures such as hooks, and the structure of the clamping protrusion is simple. It can be a straight side wall, a curved side wall, or a side wall formed by bending and connecting multiple straight side walls.

[0018] Optionally, the number of the clamping protrusions is multiple, and they are arranged at intervals in sequence around the second jack; or,

[0019] the clamping protrusion is a circumferentially closed structure around the second jack.

[0020] In the above solution, the clamping protrusions can be multiple and discretely distributed on the circumference of the second jack, or can be a circumferentially closed structure. The specific structure of the clamping protrusions can be selected according to specific circumstances.

[0021] Optionally, the first wiring piece is provided with a first buckle. When the second wiring piece is in the first position state:

[0022] the first buckle is mutually clamped with a first clamping hole on the second wiring piece; or,

[0023] the first buckle is clamped to the edge of the second wiring piece.

[0024] In the above solution, the clamping of the second wiring piece and the first wiring piece can be achieved by the mutual clamping of the first buckle on the first wiring piece and the first clamping hole on the second wiring piece or the edge of the second wiring piece.

[0025] Optionally, the docking surface is provided with a second clamping structure. When the second wiring piece is in the second position state:

[0026] the second clamping structure passes through the second jack to clamp the second wiring piece to the docking surface; or the second clamping structure is clamped to the edge of the second wiring piece.

[0027] In the above solution, the clamping of the second wiring piece and the second side wall can be achieved by the mutual clamping of the second clamping structure on the second side wall and the second jack on the second wiring piece or the edge of the second wiring piece.

[0028] Optionally, the base, the first wiring piece and the second wiring piece are integrally formed, and the first wiring piece and the second wiring piece are rotationally connected through a thin-wall structure.

[0029] In the above solution, by arranging a thin-wall structure between the first wiring piece and the second wiring piece, the rotational connection between the first wiring piece and the second wiring piece is realized, and the base, the first wiring piece and the second wiring piece are integrally formed, so that the terminal wiring board can be integrally formed, without the need to install the first wiring piece and the second wiring piece subsequently, and can be directly used after processing.

[0030] The present invention also provides a refrigerator, including a box body structure and the above-mentioned terminal wiring board. The box body structure has an installation hole, and the terminal wiring board is fixed at the installation hole.

[0031] The present invention also provides a household appliance, including the above-mentioned terminal wiring board.

[0032] The terminal socket board used in the above refrigerator or household appliance can carry two types of terminals with different models, but occupies a relatively small volume. Neither the socket board nor the inner liner of the refrigerator is prone to deformation. Moreover, after using one jack, the remaining jack does not need to be sealed, nor does it need to be designed with a sealing structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0047] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0048] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It 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 operated in a specific orientation, and thus cannot be construed as a limitation to the present invention.

[0049] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0050] For the convenience of assembly, wire harness terminals inside electrical appliances such as refrigerators are generally fixed using a patch panel. Different refrigerator configurations mean that different wire harness terminals need to be used, and thus different patch panel sockets are required for mounting. In order to make the patch panel as universal as possible, multiple sockets with different sizes are usually opened on a patch panel to enable the mounting of multiple types of wire harness terminals. The problem is that the size of such patch panels is generally large, resulting in poor flatness of the sealing surface of the patch panel and poor cooperation with the box liner, which is prone to material leakage. In addition, a larger patch panel means that a larger mating punching hole needs to be opened on the box liner, resulting in poor stiffness at the punching position of the box liner. Moreover, usually, multiple sockets on the patch panel are not used simultaneously. A refrigerator load scheme generally only requires the use of one patch panel notch, which leads to the need for additional sealing work for the redundant patch panel sockets.

[0051] In order to alleviate or solve the above technical problems, the present invention proposes a terminal plug board 100, including a base 50, a first plug board 10, and a second plug board 20 rotatably connected to the first plug board 10, the first plug board 10 and the second plug board 20 are respectively provided with a first plug hole 11 and a second plug hole 21, when the second plug board 20 rotates to be close to the first plug board 10, the first plug hole 11 is blocked, and the terminal plug board 100 can carry a second type of terminal 40, when the second plug board 20 rotates away from the first plug hole 11, the first plug hole 11 is exposed, and the terminal plug board 100 can carry a first type of terminal 30. In this way, the terminal plug board 100 can carry two different types of terminals, and will not take up too much space, and there is no need to seal the vacant sockets.

[0052] The terminal block 100 provided in the embodiment of the present invention is now described.

[0053] Please also read Figures 1 to 5 The terminal plug board 100 comprises:

[0054] Base 50;

[0055] A first plug-in piece 10 is disposed on the base 50 , and the first plug-in piece 10 is provided with a first plug-in hole 11 for fixing a first type of terminal 30 ; and

[0056] The second plug piece 20 is rotatably connected to the base 50, and the second plug piece 20 is provided with a second plug hole 21 for fixing the second type of terminal 40;

[0057] The second plug piece 20 has a first position state and a second position state;

[0058] In the first position, the second plug piece 20 is rotated to be close to the first plug piece 10, the first plug hole 11 and the second plug hole 21 at least partially overlap, and the second plug piece 20 covers at least part of the periphery of the first plug hole 11. At this time, the second plug hole 21 is used to plug the second type of terminal 40;

[0059] The second position state is that the second plug-in piece 20 is rotated to a yielding position so that the first plug-in hole 11 of the first plug-in piece 10 is exposed. At this time, the first plug-in hole 11 is used to plug in the first type of terminal 30.

[0060] The terminal block 100 can be equipped with two types of terminals, namely, a first type of terminal 30 and a second type of terminal 40 , and the first type of terminal 30 and the second type of terminal 40 are different in type.

[0061] The second plug-in piece 20 can be located in the same plane or not in the same plane when in the first position state and the second position state. The first jack 11 penetrates through the first plug-in piece 10. When the first type of terminal 30 is inserted into the first jack 11, the first type of terminal 30 can be fixed at the first jack 11 to achieve the fixation of the first type of terminal 30.

[0062] The second jack 21 on the second plug-in piece 20 penetrates through the second plug-in piece 20. When the second type of terminal 40 is inserted into the second jack 21, the second type of terminal 40 can be fixed at the second jack 21 of the second plug-in piece 20. The second plug-in piece 20 can rotate relative to the first plug-in piece 10. When the second plug-in piece 20 rotates to the first position state, the second plug-in piece 20 abuts against the first plug-in piece 10, the first jack 11 and the second jack 21 are aligned, and the periphery of the first jack 11 is blocked by the second plug-in piece 20. Understandably, the centers of the first jack 11 and the second jack 21 are aligned, and the sizes of the first jack 11 and the second jack 21 are different. The size of the first jack 11 is larger than that of the second jack 21 in at least one direction, so that the second plug-in piece 20 can block at least part of the periphery of the first jack 11. Specifically, the structure of the second plug-in piece 20 near the second jack 21 blocks the periphery of the first jack 11.

[0063] Please refer to Figure 2 and Figure 3 , when the terminal wiring board 100 needs to carry the second type of terminal 40, the second plug-in piece 20 rotates to be connected to the first plug-in piece 10, at least part of the first jack 11 on the first plug-in piece 10 is blocked, and the second jack 21 on the second plug-in piece 20 is not blocked by the first plug-in piece 10. It is equivalent to that the first jack 11 is blocked and the second jack 21 is exposed. At this time, the second type of terminal 40 can be inserted into the second jack 21, and the vacant first jack 11 does not need to be sealed by a sealing structure. Please refer to Figure 4 and Figure 5 , when the terminal wiring board 100 needs to carry the first type of terminal 30, the second plug-in piece 20 rotates to be connected to the docking surface 51, the second jack 21 of the second plug-in piece 20 is blocked by the docking surface 51, and the first jack 11 is exposed. At this time, the first type of terminal 30 can be inserted into the first jack 11, and the vacant second jack 21 does not need to be sealed by a sealing structure.

[0064] The terminal plug board 100 in the above embodiment includes a base 50, a first plug board 10 and a second plug board 20, and the first plug board 10 and the second plug board 20 are respectively provided with a first plug hole 11 and a second plug hole 21. When the second type of terminal 40 needs to be fixed, the second plug board 20 is rotated to be close to the first plug board 10, the first plug hole 11 is blocked, the second plug hole 21 is exposed, and the second type of terminal 40 is plugged and fixed in the second plug hole 21; when the first type of terminal 30 needs to be fixed, the second plug board 20 is rotated to a yield position, the first plug hole 11 is exposed, and the first type of terminal 30 is plugged in the first plug hole 11. In this way, the terminal plug board 100 can carry two different types of terminals, but the occupied volume is small, the plug board and the box are not easy to deform, and after using one of the plug holes, the other remaining plug hole does not need to be sealed, and there is no need to design a sealing structure.

[0065] In some embodiments of the present invention, the first plug hole 11 and the second plug hole 21 are both square holes or structures similar to square holes, such as rectangular holes, or hole structures formed by depressions of the side walls of the rectangular holes based on the rectangular holes.

[0066] In some embodiments, the size of the first jack 11 in the first direction is larger than the size of the second jack 21 in the first direction, and the first direction may be the length direction of the first jack 11. In this way, when the second plug 20 is connected to the first plug 10, at least two sides of the first jack 11 in the first direction are blocked.

[0067] In some embodiments, the size of the first jack 11 in the second direction is larger than the size of the second jack 21 in the second direction, and the second direction may be the width direction of the first jack 11. In this way, when the second plug-in piece 20 is connected to the first plug-in piece 10, at least two sides of the first jack 11 in the second direction are blocked.

[0068] In some embodiments of the present invention, the size of the first jack 11 in the first direction is larger than the size of the second jack 21 in the first direction, and the size of the first jack 11 in the second direction is larger than the size of the second jack 21 in the second direction. In this way, when the second plug-in piece 20 is connected to the first plug-in piece 10, each inner wall of the first jack 11 is blocked.

[0069] In some embodiments of the present invention, the first jack 11 and the second jack 21 may also be circular, and the diameter of the first jack 11 is larger than the diameter of the second jack 21, so that when the second plug-in piece 20 is connected to the first plug-in piece 10, the inner wall of the first jack 11 is blocked, and the second jack 21 is equipped with a second type of terminal 40.

[0070] In some embodiments of the present invention, see Figure 1 , Figure 2 andFigure 4 The second plug-in piece 20 is provided with a first clamping structure 22 near the second jack 21 for clamping on the inner wall of the first jack 11. When the second plug-in piece 20 rotates relative to the first plug-in piece 10 to be connected to the first plug-in piece 10, the first clamping structure 22 can cooperate with the inner wall of the first jack 11 so that the second plug-in piece 20 is clamped on the first plug-in piece 10, and the second type of terminal 40 can be directly inserted into the second jack 21 for use. Herein, the area where the second plug-in piece 20 is near the second jack 21 can be understood as the plate structure near the area where the second jack 21 is opened on the second plug-in piece 20.

[0071] By providing the first clamping structure 22 near the second jack 21 of the second plug-in piece 20, the second plug-in piece 20 can be clamped with the first jack 11 through the first clamping structure 22, and the second plug-in piece 20 can be clamped on the first plug-in piece 10, so that the second type of terminal 40 can be stably carried on the second jack 21.

[0072] In some embodiments, the number of the first clamping structures 22 can be multiple, and the multiple first clamping structures 22 are arranged around the inner wall of the first jack 11, which can fix the second plug-in piece 20 more stably on the first plug-in piece 10.

[0073] In some embodiments of the present invention, please refer to Figure 1 、 Figure 2 and Figure 4 The first clamping structure 22 includes a clamping protrusion 221 that is at least partially shaped like the first jack 11. The clamping protrusion 221 protrudes from the side of the second plug-in piece 20 facing the first plug-in piece 10, and the outer wall of the clamping protrusion 221 is in interference fit with the inner wall of the first jack 11. The first clamping structure 22 includes the clamping protrusion 221, and the clamping protrusion 221 is at least partially shaped like the first jack 11. The shape and size of the outer wall of the clamping protrusion 221 are at least the same as those of the inner wall of the first jack 11. When the clamping protrusion 221 is inserted into the first jack 11, the clamping protrusion 221 just fits tightly with the first jack 11, and the second plug-in piece 20 will not fall off the first plug-in piece 10 freely, which can make the connection between the second plug-in piece 20 and the first plug-in piece 10 more stable.

[0074] The outer wall of the clamping protrusion 221 is in interference fit with the inner wall of the first jack 11. When fixing the second plug-in piece 20 on the first plug-in piece 10, applying a little external force to the second plug-in piece 20 can squeeze the clamping protrusion 221 into the first jack 11. Under the action of the frictional force between the two, the first plug-in piece 10 and the second plug-in piece 20 are fixed to each other. In this way, there is no need to set structures such as hooks. The structure of the clamping protrusion 221 is simple, and it can be a straight side wall, a curved side wall, or a side wall formed by bending multiple straight side walls.

[0075] In some embodiments, referring to Figure 4 and Figure 5 , the number of the clamping protrusions 221 is multiple, and they are sequentially arranged at intervals around the second jack 21. When the second wiring piece 20 is connected to the first wiring piece 10, each clamping protrusion 221 is in interference fit with the corresponding position of the first jack 11. There is a gap between two adjacent clamping protrusions 221. When each clamping protrusion 221 is inserted into the first jack 11 simultaneously, each clamping protrusion 221 is easier to be inserted. Even if there are certain machining tolerances when the clamping protrusion 221 and the first jack 11 are formed, it will not cause the clamping protrusion 221 to be unable to be inserted into the first jack 11. Moreover, the clamping protrusion 221 in this embodiment is also easier to process and has a higher yield rate.

[0076] Optionally, the structures of the clamping protrusions 221 may be the same or different, and they can be designed according to the corresponding positions of the first jack 11 by copying the shape.

[0077] Optionally, the number of the clamping protrusions 221 is two, which are respectively arranged on the opposite sides of the second jack 21. Correspondingly, when the second wiring piece 20 is fixed to the first wiring piece 10, the two clamping protrusions 221 are respectively closely attached to the opposite sides of the first jack 11.

[0078] Optionally, the number of the clamping protrusions 221 is four, which are respectively arranged on the four side surfaces of the second jack 21. Correspondingly, when the second wiring piece 20 is fixed to the first wiring piece 10, the four clamping protrusions 221 are respectively closely attached to the four sides of the first jack 11.

[0079] In some embodiments of the present invention, the clamping protrusion 221 is a circumferentially closed structure around the second jack 21. It can be understood that in the circumferential direction around the second jack 21, the clamping protrusion 221 is a continuous structure. When the second wiring piece 20 is fixed to the first wiring piece 10, the side walls of the second jack 21 are respectively in close contact with the corresponding positions of the clamping protrusion 221. Since the contact area between the inner wall of the first jack 11 and the outer wall of the clamping protrusion 221 is large, the locking force between the two is large. After the clamping protrusion 221 extends into the first jack 11, the second wiring piece 20 is more likely to be loosened from the first wiring piece 10.

[0080] In some embodiments of the present invention, the first clamping structure 22 includes a connecting portion and a hook. The two ends of the connecting portion are respectively connected to the second wiring piece 20 and the hook. When the second wiring piece 20 is connected to the first wiring piece 10, the connecting portion passes through the first jack 11, and the hook is clamped at a position close to the first jack 11 of the first wiring piece 10. In this way, the second wiring piece 20 and the first wiring piece 10 are clamped to each other.

[0081] Optionally, there are two first clamping structures 22 , and the two first clamping structures 22 are respectively clamped at two opposite sides of the first plug hole 11 .

[0082] In some embodiments of the present invention, the first plug piece 10 is provided with a first buckle, and the second plug piece 20 is correspondingly provided with a first clamping hole. When the second plug piece 20 is in the first position, the first buckle and the first clamping hole on the second plug piece 20 are mutually clamped. In this way, the second plug piece 20 can be clamped to the first plug piece 10. In this embodiment, the inner wall of the first plug hole 11 is not used to clamp the second plug piece 20, but the first buckle on the first plug piece 10 and the first clamping hole on the second plug piece 20 are directly clamped to each other without being restricted by the first plug hole 11.

[0083] In other embodiments, the first plug-in piece 10 is provided with a first locking hole, and the second plug-in piece 20 is provided with a first buckle. When the second plug-in piece 20 is in the first position, the first buckle and the first locking hole on the second plug-in piece 20 are engaged with each other.

[0084] In some embodiments of the present invention, the first plug piece 10 is provided with a first buckle, and when the second plug piece 20 is in the first position, the first buckle is engaged with the edge of the second plug piece 20. When the second plug piece 20 is in the first position, the second plug piece 20 is connected to the first plug piece 10 by engaging the first buckle with the edge of the second plug piece 20. In this embodiment, there is no need to provide a clamping hole on the second plug piece 20, and the first buckle is engaged with the second plug piece 20 by utilizing the edge of the second plug piece 20, so that the structure of the second plug piece 20 is relatively simple.

[0085] In other embodiments, the second plug-in piece 20 is magnetically attracted to the first plug-in piece 10 in the first position. Specifically, the first plug-in piece 10 is provided with a first magnetic attraction component, and the second plug-in piece 20 is provided with a second magnetic attraction component, so that when the second plug-in piece 20 is rotated to be close to the first plug-in piece 10, the first plug-in piece 10 and the second plug-in piece 20 are magnetically fixed to each other.

[0086] In some embodiments of the present invention, see Figure 4 and Figure 5 The base 50 is provided with a resting surface 51 for the second plug-in piece 20 to rest against when the second plug-in piece 20 rotates to the yielding position. The resting surface 51 is provided to stably maintain the second plug-in piece 20 in the second position, preventing the second plug-in piece 20 from rotating in the reverse direction and blocking the first plug hole 11. In other embodiments, the second plug-in piece 20 may not rest against other structures when it rotates to the yielding position.

[0087] In some embodiments of the present invention, see Figure 4 and Figure 5, a docking surface 51 is provided with a second clamping structure 511. When the second plug-in piece 20 is in the second position state: the second clamping structure 511 passes through the second jack 21 to clamp the second plug-in piece 20 to the docking surface 51. When the second plug-in piece 20 is in the second position state, it needs to be connected to the docking surface 51 so that the first jack 11 is exposed. Specifically, the second clamping structure 511 on the docking surface 51 is clamped at the second jack 21 of the second plug-in piece 20.

[0088] By providing the second clamping structure 511 on the docking surface 51 and the second clamping structure 511 being in clamping cooperation with the second jack 21, the second plug-in piece 20 can be fixed in the second position state, making the first jack 11 exposed for the first type of terminal 30 to be inserted.

[0089] In some embodiments, the outer peripheral wall of the second clamping structure 511 is in interference fit with the inner peripheral wall of the second jack 21, and thus the second plug-in piece 20 can be fixed to the docking surface 51.

[0090] Optionally, the second clamping structure 511 includes a clamping portion that is at least partially shaped to conform to the second jack 21. The clamping portion is formed by protruding from the side of the second plug-in piece 20 facing the docking surface 51, and the outer wall of the clamping portion is in interference fit with the inner wall of the second jack 21. The second clamping structure 511 includes a clamping portion that is at least partially shaped to conform to the second jack 21. The shape and size of the outer wall of the clamping portion are at least the same as the shape and size of the inner wall of the second jack 21. When the clamping portion is inserted into the second jack 21, the clamping portion just fits tightly with the second jack 21, and the second plug-in piece 20 will not fall off freely from the first plug-in piece 10, which can make the connection between the second plug-in piece 20 and the docking surface 51 more stable.

[0091] In some embodiments, the number of clamping portions is multiple and can be arranged at intervals around the second jack 21 in sequence. When the second plug-in piece 20 is connected to the docking surface 51, each clamping portion is in interference fit with the corresponding position of the second jack 21. There is a gap between adjacent two clamping portions. When each clamping portion is inserted into the second jack 21 at the same time, each clamping portion is easier to be inserted. Even if there are certain machining tolerances when the clamping portion and the second jack 21 are formed, it will not cause the clamping portion to be unable to be inserted into the second jack 21. Moreover, the clamping portion in this embodiment is also easier to process and has a higher yield rate.

[0092] In some embodiments, the clamping portion is a circumferentially closed structure. It can be understood that in the circumferential direction around the second jack 21, the clamping portion is a continuous structure. When the second plug-in piece 20 is fixed to the docking surface 51, the respective side walls of the second jack 21 are in close contact with the respective positions of the clamping portion. Since the contact area between the inner wall of the second jack 21 and the outer wall of the clamping portion is relatively large, the locking force between the two is relatively large. After the clamping protrusion 221 extends into the second jack 21, the second plug-in piece 20 is more likely to become loose from the docking surface 51.

[0093] In some embodiments of the present invention, the docking surface 51 is provided with a second clamping structure 511. When the second plug-in piece 20 is in the second position state: the second clamping structure 511 is clamped to the edge of the second plug-in piece 20. When the second plug-in piece 20 is in the second position state, through the clamping of the second clamping structure 511 to the edge of the second plug-in piece 20, the second plug-in piece 20 is connected to the docking surface 51. In this embodiment, there is no need to provide a clamping hole on the second plug-in piece 20. The second clamping structure 511 clamps to the second plug-in piece 20 by using the edge of the second plug-in piece 20, making the structure of the second plug-in piece 20 relatively simple.

[0094] In other embodiments, the second plug-in piece 20 magnetically attracts the first plug-in piece 10 when in the second position state. Specifically, a third magnetic attracting member is provided on the docking surface 51, and a fourth magnetic attracting member is provided on the second plug-in piece 20. Thus, when the second plug-in piece 20 rotates to be close to the docking surface 51, the docking surface 51 and the second plug-in piece 20 are magnetically attracted and fixed to each other.

[0095] In some embodiments of the present invention, the first plug-in piece 10 and the docking surface 51 are in the same plane, and the second plug-in piece 20 needs to rotate 180 degrees when rotating from the first position state to the second position state.

[0096] In some embodiments of the present invention, the first plug-in piece 10 and the docking surface 51 are arranged at an obtuse angle, and the second plug-in piece 20 needs to rotate 90 to 180 degrees when rotating from the first position state to the second position state. When the first plug-in piece 10 and the docking surface 51 are arranged at an obtuse angle, firstly, the rotation angle of the second plug-in piece 20 can be reduced, and secondly, when the angle between the first plug-in piece 10 and the docking surface 51 is relatively large, it will not affect the insertion of the wire harness terminal.

[0097] In some embodiments of the present invention, please refer to Figures 1 to 5, the base 50 has a recessed structure 52 formed by recessing. The first plug-in piece 10 is the inner wall of the recessed structure adjacent to the docking surface 51. The recessed structure 52 is recessed from the base 50. Both the recessed structure 52 and the base 50 are thin-walled structures. The first plug-in piece 10 is one of the inner walls of the recessed structure, and this inner wall of the recessed structure is adjacent to the docking surface 51. In this way, the second plug-in piece 20 can easily rotate between the first plug-in piece 10 and the docking surface 51.

[0098] A recessed structure 52 is provided on the base 50, thereby constructing an inner wall (the first plug-in piece 10) adjacent to the docking surface 51 inside the recessed structure 52, making there be a certain included angle between the first plug-in piece 10 and the docking surface 51, which is convenient for the installation of the wire harness terminal. Especially when the second plug-in piece 20 is connected to the docking surface 51, it can prevent the wire harness terminal from interfering with the second plug-in piece 20.

[0099] In some embodiments, the cross-sectional dimension of the recessed structure 52 gradually decreases from the base 50 to the direction away from the base 50, making the inner walls of the recessed structure 52 all inclined relative to the base 50. Correspondingly, the first plug-in piece 10 and the docking surface 51 are arranged at an obtuse angle.

[0100] In some embodiments of the present invention, the first plug-in piece 10 and the second plug-in piece 20 are rotatably connected through a rotating shaft. Optionally, a hinge shaft is provided at the connection of the first plug-in piece 10 and the second plug-in piece 20, and the hinge shaft passes through the first plug-in piece 10 and the second plug-in piece 20. Optionally, one of the first plug-in piece 10 and the second plug-in piece 20 has a convex shaft, and the other has a concave shaft hole. Through the cooperation of the convex shaft and the concave shaft hole, the rotational connection between the first plug-in piece 10 and the second plug-in piece 20 is realized.

[0101] In some embodiments of the present invention, please refer to Figures 1 to 5 , the first plug-in piece 10 and the second plug-in piece 20 are rotatably connected through a thin-walled structure. The thicknesses of the first plug-in piece 10 and the second plug-in piece 20 are greater than the thickness of the thin-walled structure, and the thin-walled structure can be bent and deformed. In this way, the first plug-in piece 10 and the second plug-in piece 20 can rotate relative to each other.

[0102] In some embodiments of the present invention, please refer to Figure 1 and Figure 5 , the base 50, the first plug-in piece 10 and the second plug-in piece 20 are integrally formed, and the first plug-in piece 10 and the second plug-in piece 20 are rotatably connected through a thin-walled structure. The thicknesses of the first plug-in piece 10 and the second plug-in piece 20 are greater than the thickness of the thin-walled structure, and the thin-walled structure can be bent and deformed. The integral formation of the base 50, the first plug-in piece 10 and the second plug-in piece 20 can be understood as the integral formation of the terminal plug-in board 100. The terminal plug-in board 100 can be obtained through one-time processing without subsequent installation.

[0103] By providing a thin-wall structure between the first plug piece 10 and the second plug piece 20, a rotational connection between the first plug piece 10 and the second plug piece 20 is achieved, and the first plug piece 10 and the second plug piece 20 are integrally formed, so that the terminal plug board 100 can be integrally formed without the need to subsequently install the first plug piece 10 and the second plug piece 20, and can be used directly after processing.

[0104] See also Figure 6 The present invention further provides a refrigerator, comprising a box structure 200 and a terminal plug board 100 in any of the above embodiments, wherein the box structure 200 has a mounting hole, and the terminal plug board 100 is fixed at the mounting hole.

[0105] The refrigerator provided by the present invention adopts the above-mentioned terminal plug board 100, and the terminal plug board 100 includes a base 50, a first plug board 10 and a second plug board 20, and the first plug board 10 and the second plug board 20 are respectively provided with a first plug hole 11 and a second plug hole 21. When the second type of terminal 40 needs to be fixed, the second plug board 20 rotates to abut against the first plug board 10, the first plug hole 11 is blocked, the second plug hole 21 is exposed, and the second type of terminal 40 is plugged and fixed in the second plug hole 21; when the first type of terminal 30 needs to be fixed, the second plug board 20 rotates to a yield position, the first plug hole 11 is exposed, and the first type of terminal 30 is plugged in the first plug hole 11. In this way, the terminal plug board 100 can carry two different types of terminals, but the occupied volume is small, the plug board and the box are not easy to deform, and after using one of the plug holes, the other remaining plug hole does not need to be sealed, and there is no need to design a sealing structure.

[0106] In some embodiments of the present invention, a sealing member is provided between the terminal block 100 and the box structure 200 , so as to seal the gap between the terminal block 100 and the box structure 200 .

[0107] Optionally, the sealing element is sealing foam.
