Description

Technical Field

[0001] This utility model relates to the field of pump technology, and more specifically, to a heat insulation plate adapter for pumps and a pump unit. Background Technology

[0002] The pump unit structure includes a motor and a control box. The circuit board is installed inside the control box and connected to the motor via a cable adapter. To prevent heat from the motor from being conducted into the control box, a heat insulation plate is preferably installed between the motor base and the control box. Since the heat insulation plate isolates the motor base and control box, and the cable adapter needs to connect both the motor and control box simultaneously, the installation fit between the cable adapter and the heat insulation plate is crucial. Currently, a common approach is to leave sufficient clearance at the edge of the heat insulation plate. The cable adapter can then pass through this clearance and be installed separately with both the motor and control box, thus achieving independent installation of the heat insulation plate and the cable adapter without interference. However, this method involves a more complex assembly process during production and installation, increasing the cumulative error in fit, resulting in higher production costs for the heat insulation plate and cable adapter, reduced production efficiency, and further increasing the overall cost of the pump.

[0021] 3. Beneficial effects

[0022] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0023] This utility model discloses a pump heat insulation plate adapter device, in which a conductive element is integrally formed on the heat insulation plate, so as to realize the functions of heat insulation and wire connection at the same time with a heat insulation plate. Since the two are integrated structures, only the overall component needs to be installed and fixed during installation and assembly, reducing the complexity of the assembly process and assembly time, reducing cumulative errors, effectively improving production efficiency and product stability, and also effectively saving processing raw materials and processing mold costs.

[0024] The present invention provides a pump heat insulation plate adapter device in which the first and second electrically pluggable connectors are staggered on both sides of the plate body in a transverse direction relative to their plugging direction.

[0025] This utility model discloses a pump heat insulation plate adapter device, in which the conductive element is an independent integral molded part. First, the conductive body and the outer shell are integrally injection molded to ensure the relative position and size accuracy of the conductive body. This avoids the problem of deformation and displacement caused by the large injection pressure when the conductive body is directly injection molded with the heat insulation plate. Then, the individual conductive element and the heat insulation plate are injection molded a second time. At this time, the relative position of the conductive body has been fixed and the strength has been effectively enhanced. It is difficult to deform during the second injection molding stage of the heat insulation plate, thereby ensuring the product accuracy and strength. Attached Figure Description

[0048] The present invention will be further described below with reference to the embodiments.

[0049] Example

[0050] Combination Figures 1-14 This embodiment provides a pump unit, including:

[0051] The control box 100 includes a box base 110 and an electronic control board 120 disposed in the inner cavity of the box base 110.

[0052] The motor 200 includes a base 210 and a motor body 220 disposed in the inner cavity of the base 210.

[0053] The heat insulation board 300 includes a board body 310, which is installed between the box base 110 and the machine base 210 to block heat transfer between the box base 110 and the machine base 210, and to prevent a large amount of heat in the machine base 210 from being conducted into the control box 100. Specifically, the heat insulation board 300 has multiple sets of first mounting parts 312 on the side facing the box base 110. The first mounting parts 312 have bolt mounting holes for fixing to the box base 110 by bolt fastening. The heat insulation board 300 also has multiple sets of second mounting parts 316 on the side facing the machine base 210, which can be fixed to the machine base 210 by bolt fastening.

[0054] It should be noted that in this design, a conductive element 400 is also provided on the board body 310. The conductive element 400 has a first electrically pluggable connector 401 and a second electrically pluggable connector 402. The first electrically pluggable connector 401 is located on the side of the board body 310 facing the housing 110 and is electrically connected to the control board 120. The second electrically pluggable connector 402 is located on the side of the board body 310 facing the base 210 and is electrically connected to the motor body 220, specifically to the motor stator assembly. The conductive element 400 is at least partially located between the board bodies 310. The conductive element 400 and the board body 310 are integrally formed and insulated from each other. That is, the conductive element 400 is used to achieve electrical connection between the control board 120 and the motor body 220, while the board body 310 provides thermal insulation. The conductive element 400 and the board body 310 are insulated from each other and cannot be electrically connected. In practice, the conductive element 400 can adopt a pin structure.

[0055] This design integrates a conductive element 400 onto the insulation plate 300 to form a pump insulation plate adapter, enabling both insulation and cable transfer functions to be achieved with a single insulation plate 300. Since the two are integrated into one structure, only the fixed component needs to be installed during assembly, reducing the complexity and time of the assembly process, minimizing cumulative errors, and effectively improving production efficiency and product stability. Furthermore, merging the traditional cable transfer component and the insulation plate 300 component into a single component also effectively saves on processing raw materials and mold costs, greatly improving product production efficiency and market competitiveness.

[0056] Combination Figures 1 to 5As shown, in this design, the housing 110 is installed at the tail end of the base 210 in the axial direction, and the plate body 310 is installed between the relatively close end walls of the housing 110 and the base 210. Taking the base 210 as a circular annular seat with a cross-section, that is, the housing 110 is set at the tail end along the axial length direction of the base 210. The housing 110 and the base 210 are arranged vertically in an axial manner. At this time, the heat generated inside the motor can be easily transferred directly to the housing 110. Placing the plate body 310 between the two not only makes it easier to block heat, but also makes it easier for the conductive elements 400 on both sides of the plate to be connected vertically to the control board 120 and the motor body 220.

[0057] As different implementations, the conductive element 400 can be directly integrally formed with the board body 310. For example, if a conductive pin is used as the conductive element 400, it can be integrally formed with the board body 310 by injection molding or other molding methods. In some other preferred embodiments, the conductive element 400 includes an internal conductive body and an outer shell covering the outside of the conductive body. For example, if the conductive pin is used as the conductive body, an outer shell is formed on the outside of the conductive pin. The two ends of the conductive body are a first electrical plug-in connector 401 and a second electrical plug-in connector 402, both of which extend beyond the outer shell. The outer shell and the conductive body are integrally formed. In this case, the conductive body and the outer shell are integrally formed first, forming a pre-positioning installation and structural reinforcement of the conductive body. Furthermore, the outer shell of the conductive element 400 is at least partially located inside the board body 310, and both the first electrical plug-in connector 401 and the second electrical plug-in connector 402 extend beyond the surface of the board body 310. The outer shell of the conductive element 400 and the board body 310 are integrally formed. In this case, the conductive element 400 and the board body 310 are formed in two stages: the conductive body and the outer shell of the conductive element 400 are first integrally formed as separate components, and then the already formed conductive element 400 is integrally formed with the board body 310. In practice, the integral forming method includes various methods such as injection molding. For example, the conductive body and the outer shell of the conductive element 400 can be integrally injection molded; or the already formed conductive element 400 can be integrally injection molded with the board body 310; or both stages of forming can be done using injection molding.

[0058] In some embodiments, combined with Figures 6-10As shown, the first electrically pluggable connector 401 and the second electrically pluggable connector 402 of the conductive element 400 are staggered on both sides of the board body 310 in a lateral direction relative to their plugging and unplugging direction, and both extend beyond the board surface of the board body 310; the first electrically pluggable connector 401 and the second electrically pluggable connector 402 are electrically connected by a conductive connector 403, which is at least partially wrapped inside the board body 310 and extends laterally inside the board body 310, with the plugging and unplugging direction being the vertical installation direction. Taking a circular plate body 310 as an example, the first and second electrically pluggable connectors 401 and 402 both extend axially on both sides of the plate body 310, while the conductive connector 403 extends radially within the plate body 310. Thus, the conductive elements 400 form a Z-shaped distribution. This design, which staggers the first and second electrically pluggable connectors 401 and 402, improves the adaptability of the heat insulation plate 300. By adjusting the lateral staggered position, it can accommodate different sizes of the electrical control board 120 and the motor body 220. Similarly, the conductive connector 403 can also be distributed obliquely or bent within the plate body 310, as long as the staggered arrangement of the first and second electrically pluggable connectors 401 and 402 can be achieved.

[0059] In traditional technology, the pins of the outgoing wire adapter often pass through the heat insulation plate 300 in a straight line, combined with... Figure 10 In terms of the top and bottom positions, the first electrical pluggable connector 401 and the second electrical pluggable connector 402 are completely aligned vertically. Figure 5 As shown in the diagram, it is essential that the plug-in connection points on the control board 120 and the motor body 220 be perfectly aligned vertically. However, in practice, the dimensions of the control board 120 and the motor body 220 often differ significantly, making it impossible for their plug-in connection points to be perfectly aligned vertically. This makes it difficult to adapt the traditional linear pin method, and may even require adjustments to the size of the control board 120 or the motor body 220, resulting in an increase in the volume of the pump body structure and an increase in overall cost.

[0060] In this design, a laterally extending conductive connector 403 is provided between the first electrically pluggable connector 401 and the second electrically pluggable connector 402, allowing the first electrically pluggable connector 401 and the second electrically pluggable connector 402 to be staggered. According to actual needs, the lateral positions of the first electrically pluggable connector 401 and the second electrically pluggable connector 402 can be adjusted so that they correspond to the plug-in connection positions on the control board 120 and the motor body 220, respectively. This improves the overall adaptability of the heat insulation plate 300 and the conductive element 400. When the size and specifications of the control board 120 or the motor body 220 change, the distribution position of the conductive element 400 in the partition 300 can be redesigned, and the integrated structure of the heat insulation plate 300 and the conductive element 400 can be simply replaced, making it more flexible and convenient.

[0061] Based on the above analysis, when the first electrical plug-in connector 401 and the second electrical plug-in connector 402 are staggered through the conductive connector 403, the structure of the conductive element 400 is more complex than that of a traditional linear pin, making positioning more difficult during the integral molding process with the board body 310. Therefore, a two-stage molding method is preferred. Taking injection molding as an example, in some embodiments, it is preferable to first integrally injection mold the conductive body and the outer shell, with both the first electrical plug-in connector 401 and the second electrical plug-in connector 402 extending beyond the outer shell; then, the outer shell and the board body 310 are integrally injection molded. Figure 6 The diagram shows the structure of the conductive body in the conductive element 400. The two ends of the conductive body are a first electrically pluggable connector 401 and a second electrically pluggable connector 402, respectively, and the two pluggable connectors are electrically connected through a laterally extending conductive connector 403. The conductive body is first injection molded to ensure accurate relative position and dimensions, and the outer injection-molded shell provides sufficient strength protection to prevent deformation and displacement caused by excessive injection pressure when the conductive body is directly injection molded to the heat insulation plate 300. The conductive body is first injection molded into the shape shown in the diagram. Figure 7 The independent module shown is then subjected to a second injection molding of the separately molded conductive element 400. At this point, the relative position of the conductive body has been fixed, and its strength is also effectively enhanced relative to the single conductive body. It is difficult to deform during the second injection molding stage of the heat insulation board 300, thereby ensuring the product's precision and strength.

[0062] Combination Figure 3As shown, in some embodiments, to achieve specific circuit communication between the first electrically pluggable connector 401 and the second electrically pluggable connector 402, the housing 110 and the base 210 are respectively provided with mounting holes 111 communicating with their respective internal cavities. The first electrically pluggable connector 401 passes through the mounting hole 111 on the housing 110 and is electrically connected to the electronic control board 120, and the second electrically pluggable connector 402 passes through the mounting hole 111 on the base 210 and is electrically connected to the motor body 220. To further improve the overall sealing performance of the integrated heat insulation and adapter design, sealing elements 315 are also provided between the mounting holes 111 on the housing 110 and the base 210 and the contact surfaces with the plate body 310 for sealing. The sealing element 315 can take various forms such as sealing rings or sealing soft rubber. The sealing element 315 can be located on the plate body 310 or on the box base 110 and the machine base 210. The key is to effectively seal the interface between the mounting hole 111 and the plate body 310. That is, the sealing element 315 is set between the connection between the plate body 310 and the box base 110, and between the connection between the plate body 310 and the machine base 210, to further seal and achieve the effect of preventing condensation.

[0063] It should be noted that, in some embodiments, it is further preferred that the outer shell of the conductive element 400 not only extends beyond the surface of the plate body 310, but also extends into the mounting holes 111 on the housing 110 and the base 210. That is, the outer shell of the first electrical pluggable connector 401 extends into the mounting holes 111 of the housing 110, and the outer shell of the second electrical pluggable connector 402 extends into the mounting holes 111 on the base 210. This makes the outer shell provide stronger support and protection for the first electrical pluggable connector 401 and the second electrical pluggable connector 402, preventing them from being deformed during injection molding or installation due to their low strength.

[0064] As one specific embodiment of the seal 315, in some embodiments, combined with Figure 10 As shown, the plate body 310 has an outwardly protruding first annular wall 311 on the side facing the housing 110. A groove space is formed in the first annular wall 311. The first electrical pluggable connector 401 passes through the groove space of the first annular wall 311, and the sealing member 315 is disposed in the groove space. The mounting hole 111 on the housing 110 has a mounting annular wall 112 protruding from the housing 110. The tail end of the mounting annular wall 112 fits into the groove space and abuts against the sealing member 315. Figure 3As shown, in practice, the sealing element 315 is preferably sealed with injection-molded soft rubber. Specifically, the plate body 310 and the conductive element 400 are integrally injection-molded, with a first outwardly protruding annular wall 311 formed. Then, the formed groove space is filled with sealing soft rubber through injection molding. When the plate body 310 is installed with the housing 110, the mounting annular wall 112 on the housing 110 can be embedded downwards into the sealing soft rubber, thereby ensuring an effective seal. This not only helps to block heat transfer but also prevents further condensation. Similarly, the sealing element 315 between the plate body 310 and the base 210 uses the same configuration. The plate body 310 has a protruding second annular wall 313 on the side facing the base 210. A groove space is formed in the second annular wall 313. The second electrical plug-in connector 402 passes through the groove space of the second annular wall 313. The seal 315 is made of sealing soft rubber injection molding in the groove space. The mounting hole 111 of the base 210 also has a mounting annular wall on the outside, which can cooperate to abut against the sealing soft rubber to achieve effective sealing. In practice, the seal 315 can be made of TPE or TPU sealing soft rubber injection molding; the outer shell of the conductive element 400 and the plate body 310 can be made of PA66+30GF hard rubber injection molding.

[0065] In some embodiments, preferably, a protective wall 314 protruding outward is provided on the plate surface of the plate body 310 facing the base 210. An open cavity is formed within the protective wall 314 to accommodate the second electrically pluggable connector 402, which is hidden within this open cavity. Figure 11 As shown, the protective wall 314 completely covers the second electrical plug-in connector 402, thus forming a peripheral protective cap. When the second electrical plug-in connector 402 is connected to the connection end of the motor body 220, the protective wall 314 can cover the outside of the connection position and isolate it from the outside, forming peripheral insulation protection to avoid conductive breakdown. Specifically, when the plate body 310 has a second annular wall 313 on the plate surface facing the base 210, the protective wall 314 is disposed inside the second annular wall 313, and the extension length of the protective wall 314 exceeds the second annular wall 313. A sealing member 315 is provided between the protective wall 314 and the second annular wall 313.

[0066] When further sealing is achieved using injection-molded soft rubber, in some embodiments, a first protruding rib 413 is preferably formed on the upper part of the outer shell of the conductive element 400. The first rib 413 is located inside the groove space of the first annular wall 311, and the upper surface of the first rib 413 is flush with the upper surface of the sealing element 315 inside the first annular wall 311. In practice, when injection molding the sealing soft rubber, the first rib 413 can form a stepped structure on the outer shell, which facilitates the positioning mold to press and fix the conductive element 400 from above on the first rib 413. At this time, the soft rubber is injected into the space below the first rib 413, avoiding the soft rubber from being squeezed out between the contact surface of the positioning mold and the outer shell, thus effectively ensuring the injection molding quality of the soft rubber. Similarly, a second protruding rib 414 is also formed on the lower part of the outer shell of the conductive element 400. The second rib 414 is located in the groove space of the second annular wall 313. The second rib 414 forms a stepped shape, which facilitates the mold pressing and positioning, and also helps to ensure the injection molding quality of the sealing soft rubber. Specifically, the first rib 413 is located on the outer shell of the first electrically pluggable connector 401, and the second rib 414 is located on the outer shell of the second electrically pluggable connector 402. Figure 7 Corresponding to the sequential distribution of the first electrically pluggable connector 401, the conductive connector 403, and the second electrically pluggable connector 402, the outer shell may sequentially include a first injection molding part 410, a connecting injection molding part 411, and a second injection molding part 412. A first rib 413 is disposed on the outer periphery of the first injection molding part 410, and a second rib 414 is disposed on the outer periphery of the second injection molding part 412.

[0067] To ensure precise positioning of the conductive element 400 during the two molding processes, in some embodiments, multiple sets of molding holes are provided on the oppositely distributed two sides of the outer shell of the conductive element 400. These molding holes extend inward to expose the internal conductive body, and each side of the outer shell has at least two sets of molding holes along the length of the conductive body. Combined with... Figures 6-8As shown, specifically, near the lower region of the first electrical pluggable connector 401 in the direction of the conductive connector 403, i.e., near the lower region of the first injection molded part 410, three first holes 416 are formed on each of the opposite sides of the outer shell in this region; and near the upper region of the second electrical pluggable connector 402 in the direction of the conductive connector 403, i.e., near the upper region of the second injection molded part 412, three second holes 415 are formed on each of the opposite sides of the outer shell in this region. The first holes 416 extend inward to expose the interior of the first electrical pluggable connector 401, and the second holes 415 extend inward to expose the interior of the second electrical pluggable connector 402. The three first holes 416 and three second holes 415 on each side correspond one-to-one with the upper and lower positions of the conductive body, respectively, so that each conductive pin has two holes on each side for positioning. During injection molding, positioning elements on both sides press the conductive body from the top and bottom to position it. After injection molding, the first hole 416 and the second hole 415 are formed. After the first injection molding is completed, in the second injection molding stage of the heat insulation plate 300, the interior of the heat insulation plate 300 is filled and covered with the positions of the first hole 416 and the second hole 415, which further enhances the overall positioning accuracy of the conductive element 400 and prevents deformation or displacement.

[0068] In practice, the integrated molding of the conductive element 400 and the board body 310 places higher demands on the installation accuracy and flexibility of the overall structure. In some implementation cases, the design is further optimized by providing a waist-shaped hole on the first electrical plug-in connector 401 as a plug-in connection position. The fixing connector passes through this plug-in connection position, pressing the first electrical plug-in connector 401 against the plug-in end of the control board 120, so that the first electrical plug-in connector 401 contacts and is fixed to the plug-in end of the control board 120 and is electrically connected. Specifically, fastening bolts can be used as fixing connectors. When the first electrical plug-in connector 401 is connected to the electrical control board 120, the fastening bolts pass through the corresponding connection holes on the plug-in ends of the first electrical plug-in connector 401 and the electrical control board 120 in sequence and are tightened. The first electrical plug-in connector 401 and the plug-in ends of the electrical control board 120 are pressed and fixed to achieve electrical connection. The oblong hole on the first electrical plug-in connector 401 extends along the vertical plugging direction, so that the fastening bolt has a certain vertical movement space in the oblong hole. Therefore, even if the position of the first electrical plug-in connector 401 deviates to a certain extent, the position of the fastening bolt in the oblong hole can still be adjusted to make the plug-in ends of the first electrical plug-in connector 401 and the electrical control board 120 press and conduct. This has stronger installation adaptability and flexibility. Furthermore, the waist-shaped hole is set in the one-time molding stage of the conductive element 400, that is, the one-time molding stage of the conductive body and the outer shell. It can be used as a positioning hole. The mold is equipped with a positioning post that is embedded in the waist-shaped hole to cooperate with it, so as to achieve accurate positioning of the conductive body and further ensure the precision of the one-piece molding.

[0069] In some embodiments, the preferred plate body 310 has a plate surface area that can at least completely cover the end area of ​​the housing 110 or the base 210. In practice, the end area of ​​the base 210 is generally small, and the plate surface of the plate body 310 can at least completely cover the tail end face of the base 210, thereby providing a full-coverage barrier between the housing 110 and the base 210. Similarly, when the end area of ​​the housing 110 is small, the plate surface of the plate body 310 can at least completely cover the end face of the housing 110, thereby achieving a complete barrier between the base 210 and the housing 110, satisfying a comprehensive and sufficient heat insulation effect, reducing the power consumption of the entire pump unit, and improving the pump's power, head, power consumption, hydraulic efficiency, etc. Both the first and second electrical pluggable connectors 401 and 402 extend along the thickness direction of the board body 310, facilitating direct insertion installation. The first or second electrical pluggable connector 401 is located near the peripheral edge of the board body 310, minimizing its overall volume while ensuring complete isolation, thus simplifying manufacturing. In practice, the control board 120 is generally larger than the motor body 220. Laterally, the connectors on the control board 120 face outwards than those on the motor body 220. In this case, the first electrical pluggable connector 401 can be positioned near the edge of the board body 310, effectively accommodating the connection position of the control board 120. Similarly, when the motor body 220 is larger laterally, the second electrical pluggable connector 402 can also be positioned near the peripheral edge of the board body 310.

[0070] This embodiment provides a pump heat insulation plate adapter. By integrally molding a conductive element 400 onto the heat insulation plate 300, the heat insulation plate 300 simultaneously functions as heat insulation and wire connection, reducing the number of parts and assembly process difficulty, and lowering production costs. Preferably, a two-stage injection molding method is used, where the conductive element 400 is first injection molded as a separate module, and then the heat insulation plate 300 is injection molded a second time. This effectively ensures the positional accuracy and strength of the conductive body, preventing deformation or displacement. In practice, this has effectively improved the injection molding quality and is suitable for widespread application.
