Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, specifically to a plug terminal structure, a bracket, a fan motor, and cooking equipment. Background Technology

[0002] Microwave ovens are widely used cooking appliances in kitchens, and their internal fan motor is a core component that ensures heat dissipation and stable operation. Currently, microwave oven fan motors generally use a bracket structure with three terminals for electrical connection. Its core function is to fix the conductive terminals and provide safe and reliable insulation protection to prevent short circuits or electric shock accidents.

[0003] Currently, common multi-terminal plug structures typically consist of an insulated body and multiple plug terminals fixed to it. To meet electrical safety regulations and prevent creepage or air breakdown between live terminals and external components, traditional designs increase the overall size of the insulated body to directly increase the safety distance. However, this simplistic and crude design approach inevitably leads to increased material usage and product size, contradicting the current trend towards miniaturization, lightweighting, and cost reduction in cooking equipment. Utility Model Content

[0004] In view of this, the present invention provides a plug terminal structure, bracket, fan motor and cooking equipment to solve the problem of how to meet electrical safety specifications and prevent creepage or air breakdown between live terminals and external metal parts while achieving miniaturization, lightweighting and cost reduction of cooking equipment.

[0005] In a first aspect, the present invention provides a plug terminal structure, including an insulating body and three plug terminals; the insulating body includes a plug terminal base and an outer plate; the three plug terminals are arranged in sequence at intervals and fixed to the plug terminal base; the outer plate is disposed at the end of the plug terminal base and forms a safety gap with the plug terminal located at the end.

[0006] Beneficial effects: This plug-in terminal structure, by setting up an insulated plug-in terminal holder and an outer plate, uses the plug-in terminal holder to achieve sequential and spaced fixed arrangement of three plug-in terminals, ensuring the regularity of the plug-in terminal layout and installation stability; at the same time, the outer plate is located at the end of the plug-in terminal holder and forms a safe gap with the end plug-in terminal, effectively increasing the safe creepage distance between the plug-in terminal and the outer structure, improving the safety of use, and the overall structural design is simple and reasonable, which is conducive to the miniaturization of the product and cost control.

[0007] In one alternative embodiment, the three plug terminals include a first terminal, a second terminal, and a third terminal arranged sequentially at intervals; the peripheral plate is disposed outside the third terminal and forms the safety gap between the peripheral plate and the third terminal.

[0008] Beneficial effects: By specifically setting the three terminals as the first, second, and third terminals arranged in a sequentially spaced manner, the layout of the terminals becomes more clear and orderly, facilitating precise connection in subsequent wiring operations and improving assembly efficiency. At the same time, by placing the outer plate outside the third terminal at the end of the arrangement, a safety gap is precisely constructed at the most dangerous and easily interfered-with position with external components on the outside. This strengthens the insulation protection between the third terminal and the outer structure, effectively ensuring the safe creepage distance of the third terminal and avoiding the risk of short circuits and leakage caused by the third terminal being close to external components at the end. While ensuring the critical safety distance, there is no need for excessive redundancy in the overall structure design, maintaining the compactness of the structure and the optimization of material costs.

[0009] In one optional embodiment, a first creepage distance F is provided between the first terminal and the second terminal, wherein the first creepage distance F is greater than or equal to 4 mm.

[0010] Beneficial effects: By setting the first creepage distance between the first and second terminals to be greater than or equal to 4mm, while ensuring full compliance with electrical safety standards, the design satisfies the differentiated current carrying requirements of different terminals, effectively preventing electrical risks caused by insufficient spacing. Furthermore, the compact design saves material usage and reduces production costs. Simultaneously, it indirectly expands the safety gap between the third terminal and the outer plate, enhancing overall insulation performance. The improved structure also provides more ample space for wiring operations, making installation and disassembly more convenient and efficient.

[0011] In one optional embodiment, a second creepage distance M is provided between the second terminal and the third terminal, the second creepage distance M being greater than or equal to 4 mm.

[0012] Beneficial effects: By setting the second creepage distance M between the second and third terminals to no less than 4mm, and coordinating it with the first creepage distance F, the system fully complies with electrical safety standards. This satisfies the differentiated current carrying requirements of different terminals, effectively preventing electrical risks caused by insufficient spacing. Furthermore, the compact design saves material usage and reduces production costs. Simultaneously, it indirectly expands the safety gap between the third terminal and the outer plate, enhancing overall insulation performance. The improved structure also provides more space for wiring operations, making installation and disassembly more convenient and efficient.

[0013] In one alternative embodiment, in the arrangement direction of the connector terminals, the width of the third terminal is greater than the width of the first terminal.

[0014] Beneficial effects: By setting the width of the third terminal to be greater than that of the first terminal in the arrangement direction of the plug terminals, the wider third terminal can improve the current carrying capacity and accommodate larger currents to avoid overheating. At the same time, the wider size can also enhance its structural stability during connection or assembly and reduce contact problems. Meanwhile, the first terminal keeps its width relatively narrow, which can save space and material costs while meeting its own functional requirements.

[0015] In one alternative embodiment, in the arrangement direction of the connector terminals, the width of the first terminal is equal to the width of the second terminal.

[0016] Beneficial effects: By arranging the first and second terminals in the same direction, the first and second terminals can maintain consistency in current carrying capacity and connection stability. This avoids overheating or poor contact of one terminal due to size differences, ensuring balanced circuit operation. It also achieves standardized design of the terminal structure, simplifies the production mold and assembly process, reduces manufacturing and assembly costs, and makes the terminal layout more regular. At the same time, it ensures the regularity of the terminal arrangement, helps maintain the consistency of creepage distance between adjacent terminals, and improves the overall reliability of the product.

[0017] In one alternative embodiment, in the arrangement direction of the connector terminals, the width B of the first terminal is 2.8 mm, the width C of the second terminal is 2.8 mm, and the width D of the third terminal is 4.8 mm.

[0018] Beneficial effects: By setting the width B of the first terminal and the width C of the second terminal to 2.8 mm, and the width D of the third terminal to 4.8 mm, the minimum size configuration of the terminals is achieved while meeting the rated current requirements. This ensures that the first and second terminals maintain consistency in current carrying capacity and connection stability, avoiding localized overheating or poor contact due to size differences. Furthermore, widening the third terminal allows it to accommodate larger current requirements, meeting the functional differences of various terminals. Simultaneously, the clear and standardized dimensional design simplifies production molds and assembly processes, reducing manufacturing costs. All dimensions strictly comply with safety regulations regarding the spacing of live parts, achieving a balance between structural compactness and cost control while ensuring insulation safety.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] The following is combined with Figures 1 to 5 The following describes embodiments of the present invention.

[0030] According to an embodiment of the present invention, a plug-in terminal structure 100 is provided, including an insulating body 110 and three plug-in terminals 120; the insulating body 110 includes a plug-in terminal base 111 and an outer plate 112; the three plug-in terminals 120 are arranged sequentially at intervals and fixed to the plug-in terminal base 111; the outer plate 112 is disposed at the end of the plug-in terminal base 111 and forms a safety gap with the plug-in terminals 120 located at the end.

[0031] In the above embodiments, the plug terminal structure 100, by setting the plug terminal base 111 of the insulating body 110 and the outer plate 112, uses the plug terminal base 111 to realize the sequential and spaced fixed arrangement of the three plug terminals 120, ensuring the regularity of the layout and installation stability of the plug terminals 120; at the same time, the outer plate 112 is located at the end of the plug terminal base 111 and forms a safe gap with the end plug terminal 120, which effectively increases the safe creepage distance between the plug terminal 120 and the outer structure, improves the safety of use, and the overall structural design is simple and reasonable, which is conducive to the miniaturization of the product and cost control.

[0032] In specific implementation methods, such as Figure 2 As shown, by reasonably increasing the safety gap J between the outer plate 112 and the third terminal 123, the safe creepage distance between the plug terminal 120 and the outer components can be effectively extended. This enhances its electrical insulation performance, enabling the product to maintain stable safety characteristics even under complex operating conditions.

[0033] In one embodiment, the three plug terminals 120 include a first terminal 121, a second terminal 122, and a third terminal 123 arranged sequentially at intervals; the outer plate 112 is disposed outside the third terminal 123 and forms the safety gap between the outer plate 112 and the third terminal 123.

[0034] In the above embodiment, by specifically setting the three plug terminals 120 as a first terminal 121, a second terminal 122, and a third terminal 123 arranged in sequence at intervals, the layout of the plug terminals 120 is more clear and regular, which facilitates the precise connection of subsequent plug-in operations and improves assembly efficiency. At the same time, by setting the outer plate 112 outside the third terminal 123 at the end of the arrangement, a safety gap is precisely constructed at the most dangerous position on the outside, where it is most likely to have safety interference with external components. This can strengthen the insulation protection between the third terminal 123 and the outer structure, effectively ensure the safe creepage distance of the third terminal 123, and avoid the risk of short circuit and leakage caused by the third terminal 123 being close to the outer components at the end. While ensuring the key safety distance, there is no need to carry out excessive redundant design of the overall structure, thus maintaining the compactness of the structure and the optimization of material costs.

[0035] In one embodiment, a first creepage distance F is provided between the first terminal 121 and the second terminal 122, and the first creepage distance F is greater than or equal to 4 mm.

[0036] In the above embodiment, by setting the first creepage distance between the first terminal 121 and the second terminal 122 to be greater than or equal to 4mm, while ensuring full compliance with electrical safety standards, the differentiated current carrying requirements of different plug terminals 120 are met, effectively preventing electrical risks caused by insufficient spacing; at the same time, the compact design saves material usage and reduces production costs. Simultaneously, it indirectly expands the safety gap between the third terminal 123 and the outer plate 112, enhancing overall insulation performance. Furthermore, the improved structure provides more space for plugging operations, making the installation and disassembly process more convenient and efficient.

[0037] Preferably, the first creepage distance F is set to 4 mm. This dimension has been optimized and verified to provide a minimum creepage distance that meets safety standards between adjacent live parts while ensuring that each individual terminal 120 meets the rated current intensity. This fully guarantees the insulation safety between adjacent terminals 120 and achieves an optimal balance between structural compactness and material utilization.

[0038] In one embodiment, a second creepage distance M is provided between the second terminal 122 and the third terminal 123, and the second creepage distance M is greater than or equal to 4 mm.

[0039] In the above embodiment, by setting the second creepage distance M between the second terminal 122 and the third terminal 123 to not less than 4mm, and coordinating it with the first creepage distance F, the system ensures full compliance with electrical safety standards. This satisfies the differentiated current carrying requirements of different plug terminals 120, effectively preventing electrical risks caused by insufficient spacing. Furthermore, the compact design saves material usage and reduces production costs. Simultaneously, it indirectly expands the safety gap between the third terminal 123 and the outer plate 112, enhancing overall insulation performance. The improved structure also provides more space for plugging operations, making installation and disassembly more convenient and efficient.

[0040] Preferably, the second creepage distance M is set to 4 mm. This dimension has been optimized and verified to provide a minimum creepage distance that meets safety standards between adjacent live parts while ensuring that each individual terminal 120 meets the rated current intensity. This fully guarantees the insulation safety between adjacent terminals 120 and achieves an optimal balance between structural compactness and material utilization.

[0041] In one embodiment, in the arrangement direction of the connector terminals 120, the width of the third terminal 123 is greater than the width of the first terminal 121.

[0042] In the above embodiment, the third terminal 123 is wider than the first terminal 121 in the arrangement direction of the plug terminals 120. By differentiating the width of the plug terminals 120, the wider third terminal 123 can improve the current carrying capacity and accommodate larger currents to avoid overheating. At the same time, the wider size can also enhance its structural stability during connection or assembly and reduce contact problems. Meanwhile, the first terminal 121 maintains a relatively narrow width, which can save space and material costs while meeting its own functional requirements.

[0043] In one embodiment, in the arrangement direction of the connector terminals 120, the width of the first terminal 121 is equal to the width of the second terminal 122.

[0044] In the above embodiments, the first terminal 121 and the second terminal 122 are made to have the same width in the arrangement direction of the plug terminals 120. This ensures that the first terminal 121 and the second terminal 122 maintain consistency in current carrying capacity and connection stability, preventing one of the plug terminals 120 from overheating or making poor contact due to size differences. This ensures the balance of circuit operation, achieves the standardized design of the plug terminal structure 100, simplifies the production mold and assembly process of the plug terminals 120, reduces manufacturing and assembly costs, and makes the layout of the plug terminals 120 more regular. At the same time, it ensures the regularity of the arrangement of the plug terminals 120, which helps to maintain the consistency of the creepage distance between adjacent plug terminals 120 and improves the overall reliability of the product.

[0045] In one embodiment, in the arrangement direction of the connector terminals 120, the width B of the first terminal 121 is 2.8 mm, the width C of the second terminal 122 is 2.8 mm, and the width D of the third terminal 123 is 4.8 mm.

[0046] In the above embodiments, by setting the width B of the first terminal 121 and the width C of the second terminal 122 to 2.8 mm and the width D of the third terminal 123 to 4.8 mm in the arrangement direction of the plug terminals 120, the minimum size configuration of the plug terminals 120 under the condition of meeting the rated current requirements is achieved. This ensures that the first terminal 121 and the second terminal 122 are consistent in terms of current carrying capacity and connection stability, avoiding local overheating or poor contact due to size differences. At the same time, by widening the third terminal 123, it can adapt to larger current requirements, meeting the functional differences of different plug terminals 120. Meanwhile, the clear and regular size design simplifies the production mold and assembly process, reducing manufacturing costs. All dimensions strictly comply with the safety specifications for the spacing of live parts, achieving a balance between structural compactness and cost control while ensuring insulation safety.

[0047] In a specific implementation, by setting both the first creepage distance F and the second creepage distance M to 4mm, setting the width B of the first terminal 121 and the width C of the second terminal 122 to 2.8mm, and setting the width D of the third terminal 123 to 4.8mm, the following is achieved: Figure 4 The overall structural optimization is shown. This size combination minimizes the span A from the outermost edge of the first terminal 121 to the outermost edge of the third terminal 123 while ensuring that all three terminals 120 meet electrical connection requirements and safety specifications. This achieves the optimal balance between structural compactness and production cost while ensuring product safety and functional integrity.

[0048] Specifically, such as Figure 4 As shown, under the constraint that the total width N of the terminal block structure 100 remains constant, by optimizing the internal layout to minimize the span A from the outermost edge of the first terminal 121 to the outermost edge of the third terminal 123, the safety clearance J between the terminal block 120 and the outer perimeter plate 112 can be increased simultaneously. Through the compact layout of the internal structure, the safety insulation performance of key parts is effectively improved without changing the overall external dimensions, achieving a synergistic optimization of structural space utilization and electrical safety.
