Description

Technical Field

[0001] This utility model relates to the field of refrigerator technology, specifically to an electrical terminal assembly structure for a refrigerator. Background Technology

[0002] Currently, the electrical terminals of refrigerators are directly mounted on the back of the refrigerator liner, meaning they are perpendicular to the liner. This can prevent condensation from draining from the terminal connections, potentially causing a fire at the terminal joints. Furthermore, the existing wiring terminals place the high-voltage terminals at the bottom for easy connection to the heater on the evaporator. This design allows water to drip directly onto the high-voltage terminals when draining from the low-voltage terminals above them, potentially causing a fire or electrification at the high-voltage terminal joints, posing a significant safety hazard. Utility Model Content

[0003] The purpose of this utility model is to provide an electrical terminal assembly structure for a refrigerator, aiming to solve at least one of the technical problems existing in the prior art. To achieve the above objective, the technical solution adopted by this utility model is as follows:

[0004] An electrical terminal assembly structure for a refrigerator includes a protrusion and a recess. The connecting surface of the protrusion and the recess is the mounting surface of the electrical terminal. The mounting surface forms an angle of 30°-70° with the back of the refrigerator liner. The mounting surface has mounting holes for mounting the electrical terminal. The high-voltage terminal of the electrical terminal is on top, and the low-voltage terminal is on the bottom.

[0005] As a further embodiment of this utility model: a rounded corner is provided at the junction of the upper and lower ends of the mounting surface.

[0006] As a further embodiment of this utility model, the bottom surface of the recessed portion is configured as an inclined surface.

[0007] As a further embodiment of this utility model: the top surface of the protrusion is configured as a second inclined surface.

[0008] As a further embodiment of this utility model: the two sides of the second inclined surface are connected to the side of the protrusion by an inclined surface.

[0009] As a further embodiment of this utility model: both the protrusion and the recess are provided with chamfered spherical corners on their left and right sides.

[0010] As a further embodiment of this utility model: the periphery of the junction between the protrusion and the recess and the liner of the refrigerator is provided with a No. 2 rounded corner.

[0011] This utility model has the following beneficial effects:

[0012] By incorporating an electrical terminal assembly structure on the back of the refrigerator's liner, the protruding and recessed parts of this structure combine to form the mounting surface for the electrical terminals. This mounting surface forms a 30-70° angle with the back of the liner, allowing the terminals to be installed at a large downward angle. This facilitates the smooth flow of condensate from the terminal connections, preventing backflow into the terminals and potential short circuits, fires, or leaks. Furthermore, this invention offers advantages such as low cost, simple manufacturing process, high production efficiency, reliable electrical safety, and no additional cost, while also facilitating wiring. The combination of protruding and recessed parts helps prevent condensation on the back of the liner and reduces the thickness of the air duct, indirectly increasing the refrigerator's volume. The large beveled design of the recessed part facilitates the vacuum forming of the liner and the flow of foaming liquid, while also improving connection strength and drainage, preventing the risk of water accumulation and freezing. The large beveled design of the protruding part facilitates vacuum forming and enhances the foaming strength of the refrigerator at that location. The design of the first and second rounded corners helps prevent the liner from becoming thin or cracked. The chamfered spherical corner design significantly enhances the strength of the area, preventing foam bulging and deformation, and also preventing cracking. The integrated terminal design (combining high-voltage and low-voltage terminals) improves assembly efficiency and reduces component costs; placing the high-voltage terminals above the low-voltage terminals enhances electrical safety and reliability.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0019] Furthermore, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] This utility model embodiment provides an electrical terminal assembly structure for a refrigerator. The refrigerator's liner is designed as a hollow cavity and manufactured using vacuum forming. It is then assembled and foamed with other components (such as the shell, beams, and back panel) to form the refrigerator body. The electrical terminal assembly structure disclosed in this application is located on the back of the refrigerator's liner.

[0021] Please see Figure 1 As shown, in one specific embodiment, the electrical terminal assembly structure includes a protrusion 1 and a recess 2. The protrusion 1 and the recess 2 together form the mounting surface 3 of the electrical terminal 4. The mounting surface 3 is at a 30-70° angle to the back of the box, so that the electrical terminal 4 is tilted downward at a large angle when installed. This facilitates the smooth flow of condensate at the connector of the electrical terminal 4, and prevents backflow into the interior of the electrical terminal 4, which could cause short circuits, fires, leakage, and other quality problems.

[0022] It should be noted that the electrical terminal 4 is designed as a multi-hole terminal, with a high-voltage terminal 5 and multiple low-voltage terminals 6. The high-voltage terminal 5 is connected to the heater, and the low-voltage terminals 6 are connected to components such as temperature sensors and fans. The terminal is designed with a flange mounting surface 3, on which double-sided adhesive is designed. One function of the double-sided adhesive is to fix it, and the other is to seal it to prevent leakage of foaming liquid.

[0023] Please see Figure 2As shown, mounting holes for electrical terminals 4 can be made on the mounting surface 3. The direction of the mounting holes is determined by the position of the high-voltage terminal 5 of the electrical terminal 4. After the electrical terminal 4 is installed onto the mounting surface 3 through the mounting holes, ensure that the high-voltage terminal 5 of the electrical terminal 4 is on top and the low-voltage terminal 6 is on the bottom, thus solving the major quality problem of fire-prone machines caused by existing structural defects. It is understood that, in order to provide a sealing seal for the electrical terminal 4, sealing sponge 13 can be filled at the edge between the electrical terminal 4 and the mounting hole.

[0024] Please see Figure 2 As shown, in order to facilitate vacuum forming, a rounded corner 7 is provided at the junction of the upper and lower ends of the mounting surface 3. One function is to facilitate vacuum forming and prevent the core from being too thin; another function is to increase the size of the mounting surface 3 to prevent the height of the protrusion 1 from being too high and the depth of the recess 2 from being too deep, which would affect the air duct assembly or the foam layer of the box.

[0025] Preferably, please refer to Figure 2 As shown, in one specific embodiment, the bottom surface of the recessed part 2 is set as a first inclined surface 8 structure. One function is to increase the foam layer on the back of the box to prevent condensation. Another function is to facilitate the drainage of accumulated water and prevent freezing. Yet another function is to facilitate vacuum forming and improve the reliability of vacuum forming.

[0026] In addition, the top surface of the protrusion 1 is set as the second inclined surface 9, which is conducive to the vacuum forming of the box liner and improves the structural strength at this point; small inclined surfaces 10 are set on both sides of the second inclined surface 9 to increase the size of the mounting surface 3 of the electrical terminal 4 and prevent leakage between the electrical terminal 4 and the mounting point of the box liner.

[0027] Please see Figure 1 As shown, both the protrusion 1 and the recess 2 are designed with chamfered spherical corners 11 on the left and right sides to prevent the liner from becoming thin, cracked, or collapsed, improve the connection strength at the intersection, and resist foaming deformation. The perimeter of the junction between the protrusion 1 and the recess 2 and the refrigerator liner is provided with a second rounded corner 12, which is beneficial for vacuum forming and prevents the liner from cracking.

[0028] The advantages of this utility model are:

[0029] This utility model has the advantages of low cost, simple process, high production efficiency, reliable electrical safety, no additional cost, and convenient wiring.

[0030] The design of the combination of protrusion 1 and recess 2 helps to prevent condensation on the back of the inner liner, while also reducing the thickness of the air duct and indirectly increasing the volume of the cabinet.

[0031] The recessed section features two large sloping surfaces (sloping surface 8), which facilitates the vacuum forming of the box liner and the flow of foaming liquid. It also improves the connection strength and promotes drainage, preventing the risk of water accumulation and freezing.

[0032] The design of the raised section with a large sloping surface (second sloping surface 9) is beneficial for vacuum forming and improves the foaming strength of the box in this area.

[0033] The design of the No. 1 rounded corner 7 and the No. 2 rounded corner 12 structure helps to prevent the gallbladder from becoming thin or cracked.

[0034] The chamfered spherical corner design at the corner greatly enhances the strength of the area, preventing foam bulging and deformation, and also preventing gallbladder cracking.

[0035] The integrated terminal design (combined with high-voltage terminal 5 and low-voltage terminal 6) improves assembly efficiency and reduces component costs; the high-voltage terminal 5 is designed on top of the low-voltage terminal 6, which helps to improve the safety and reliability of electrical appliances.

[0036] The electrical terminals feature a double-sided adhesive design, which improves worker assembly efficiency (replacing the existing tape sealing process) and enhances sealing reliability.

[0037] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
