Description

Technical Field

[0001] This invention relates to the field of pump programming technology, and more specifically, to a programming block, control box, and pump unit for pumps. Background Technology

[0002] Pump units are typically equipped with intelligent control boxes to perform complex functions such as pump start-up, speed regulation, protection, and status monitoring. The core of the control box is the built-in electronic control board, which carries the embedded programs that implement these functions. Updating or flashing the software onto the electronic control board is a routine and necessary maintenance operation. The standard flashing method is as follows: the operator first opens the control box casing to expose the internal electronic control board, then physically connects the connector of a dedicated programmer to the pre-installed flashing interface on the electronic control board before performing the flashing operation. After flashing, the connection must be disconnected, and the control box must be reassembled and sealed.

[0003] The aforementioned traditional programming methods present significant inconvenience and safety hazards. Each programming session requires a complete process of "opening the box - connecting - programming - disconnecting - closing the box," greatly increasing maintenance time and labor costs, reducing work efficiency, and repeatedly disassembling and reassembling the control box shell may damage other components. The pulling of the programming cable within the narrow box can also cause accidental scratches to other components. Patent CN222940670U provides an optimized programming method, directly molding the programming electrical connection components onto the control box shell, using the outer surface of the control box as the programming area. This design allows programming without opening the shell, but its practical application still has limitations in terms of convenience, and it poses greater challenges to the molding quality of the control box and electrical connection components. How to further optimize and improve the convenience and safety of programming the control board has become a crucial factor affecting the efficient maintenance and upgrading of equipment. Summary of the Invention

[0004] 1. The technical problem that the invention aims to solve In view of the inconvenience of programming the control board of the pump control box in the prior art, the present invention aims to provide a programming block for pumps, a control box and a pump unit. The programming block adopts an independent structure that is compatible with the control box and can be installed directly without disassembling the control box, and can further improve the convenience of application and processing.

[0005] 2. Technical Solution To achieve the above objectives, the technical solution provided by the present invention is as follows: A programming block for a pump according to the present invention includes: The fixing block has a mounting part configured to fit and install with the cover of the control box, so that the fixing block can be fixed on the cover and the upper surface of the fixing block is exposed on the cover. An electrical connector is integrally formed inside a fixed block. The electrical connector has a programming portion exposed on the upper surface of the fixed block, and an extension portion extending beyond the fixed block for electrical connection with an electrical control board inside the control box.

[0006] This invention employs an independent programming block structure, directly molding electrical connectors, such as pin structures, onto a fixed block to form an independent programming block module. This module can then be assembled onto the control box cover, with the electrical connectors exposed on the surface, forming the programming contact surface. The extensions of the electrical connectors can then rest against the corresponding programming holes on the control board. During use, the programmer's contacts are connected to the programming surface. Specifically, the programming block contains multiple pins forming multiple programming contact surfaces. The programmer's pins sequentially align with these multiple contact surfaces for programming. This design eliminates the need for repeated disassembly and reassembly of the cover, and the pins are molded separately from the fixed block, making molding more convenient and precise. It also effectively ensures the positional stability of the pins, reduces the molding difficulty of the pins and cover, guarantees programming accuracy, and allows the programming block to be adapted to different control box products, providing greater versatility.

[0007] Furthermore, the upper surface of the programming section of the electrical connector is flat and is flush with the upper surface of the fixing block, and the upper surface of the programming section is the programming contact surface.

[0008] Furthermore, an inclined portion extends between the top of the extension of the electrical connector and the bottom surface of the fixing block. The inclined portion gradually decreases in height from the bottom surface of the fixing block and is distributed at an angle. The inclined portion is set at the top of the extension to form a curved structure, which can deform and shrink to a certain extent when the extension is pressed against the programming hole on the control board, ensuring a tight contact and avoiding damage to the extension.

[0009] Furthermore, the electrical connector also includes a rear-bent section, which extends from one end of the burning section into the interior of the fixing block and is distributed in a bent manner within the fixing block, providing electrical connection between the burning section and the extension section. The electrical connector and the fixing block are integrally injection molded, and the rear-bent section achieves a curved distribution within the fixing block, effectively limiting movement and ensuring the molding stability with the fixing block, thus guaranteeing the overall structural strength and positional accuracy of the electrical connector.

[0010] Furthermore, the electrical connector also includes a front bend that extends from the other end of the programming section into the fixing block. Similarly, the front bend further ensures the positional stability of the electrical connector, thereby ensuring the stable distribution of the programming section on the fixing block and the stability of the programming contact surface.

[0011] Furthermore, a protruding ring is provided around the side wall of the fixing block, which is configured to fit and limit the position of the lid. During installation, the protruding ring can be used to engage with the inside of the lid for positioning and support.

[0012] Furthermore, a sealing part is provided on the upper part of the protruding ring for sealing the fixing block inside the box cover. The protruding ring is designed so that there is an installation area around the top, and a sealing part can be provided in the installation area to achieve an effective seal between the fixing block and the box cover.

[0013] This invention also provides a control box, including a base and a cover. An electronic control board is housed inside the control box. The cover has mounting holes, and a programming block for the pump, as described above, is placed within the mounting holes. The programming portion protrudes from the upper surface of the cover, while the extension portion extends into the base and is electrically connected to the electronic control board. Using this programming block, the control box cover is easier to mold, the molding quality is more guaranteed, and the programming operation is also more convenient.

[0014] Furthermore, a protruding limiting part is provided around the inner wall of the mounting hole, and the limiting part supports and limits the side wall edge of the fixing block; specifically, it can cooperate with the protruding ring part provided on the fixing block, and the protruding ring abuts against the upper part of the limiting part. Furthermore, a slot is provided on the inner wall of the mounting hole, and the slot is snapped into the mounting part on the fixing block, so that the mounting part can adopt a snap-fit ​​structure for convenient installation.

[0015] The present invention also provides a pump unit, including a pump body and a control box as described above, the control box being mounted on the pump body. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] The present invention will be further described below with reference to embodiments.

[0022] Example Combination Figures 1-7 As shown, this embodiment provides a pump unit, including a control box and a pump body 500. The control box is mounted on the pump body 500 and electrically connected to the internal motor. The control box includes a box base 200 and a box cover 100, and an electronic control board 210 is distributed within the assembly formed by the box base 200 and the box base 100. This embodiment further optimizes the design of the programming structure of the box cover 100. A mounting hole 110 is provided on the box cover 100, and a programming block is adapted to be installed in the mounting hole 110. The programming block has a programming contact surface exposed on the surface of the box cover 100, and an extension 605 that penetrates the box cover 100 and connects with the programming hole on the electronic control board 210. This allows the programming process to be performed directly by the programmer 400 and the programming contact surface of the programming block without opening the box cover 100, greatly improving the convenience of programming.

[0023] Specifically, combined Figure 3 and Figure 4 As shown, in this embodiment, the programming block includes a fixing block 300 as the main support, and the fixing block 300 is provided with a mounting part 312. The mounting part 312 is used to be fitted and installed with the cover 100 of the control box, so that the fixing block 300 can be fixed on the cover 100, and the upper surface of the fixing block 300 is exposed on the cover 100. Specifically, the mounting part 312 can adopt a snap-fit ​​structure, and a corresponding slot 112 can be provided on the inner wall of the mounting hole 110. The slot 112 and the mounting part 312 are snap-fitted together. In practice, the mounting part 312 can also adopt other structural forms, as long as it can be stably fitted into the mounting hole 110 and kept in a stable position, which will not be described in detail.

[0024] To enable the electrical connection for programming, the fixing block 300 is also provided with an electrical connector. The electrical connector is integrally formed inside the fixing block 300. The electrical connector has a programming part 601 exposed on the upper surface of the fixing block 300, and an extension part 605 extending beyond the fixing block 300. The extension part 605 extends to be able to be electrically connected to the electronic control board 210 in the control box, specifically to be able to contact the programming hole on the electronic control board 210.

[0025] In this embodiment, multiple pins are used as an example. Multiple pins are integrally injection molded inside the fixing block 300. Each pin has a programming section 601 at its upper part, which protrudes from the upper surface of the fixing block 300, i.e., from the upper surface of the cover 100, allowing direct contact with the programmer 400. The pin ends pass downwards through the fixing block 300 and the cover 100, extending to contact the programming hole on the control board 210. This allows for electrical connection between the programmer 400 and the control board 210, enabling programming.

[0026] In this embodiment, the pins are directly molded inside the fixing block 300, which can be movably mounted on the cover 100. Compared to directly molding the pins onto the cover 100, injection molding is simpler and easier to control and ensure the positional accuracy and molding quality of multiple pins. This ensures the pins are stable and not easily deformed, thereby improving the positional accuracy and reliability during programming and docking, and guaranteeing programming quality and reliability. Furthermore, the programming block can be removed and adapted to other control boxes for programming as needed, offering greater application flexibility and adaptability. In case of unexpected failures, the programming block or the cover can be replaced individually.

[0027] Specifically, to ensure the stability of the contact of the programmer 400, the upper surface of the programming section 601 of the electrical connector is flat and is flush with the upper surface of the fixing block 300, so that the programming contact surface can conduct current and the pins on the programmer 400 can make direct and stable contact.

[0028] Furthermore, an inclined portion 604 extends between the top of the extension 605 of the electrical connector and the bottom surface of the fixing block 300. The inclined portion 604 gradually decreases in height from the bottom surface of the fixing block 300 and is distributed at an incline. By utilizing the inclined portion 604, a curved structure is formed at the top of the extension 605. When pressed against the programming hole on the control board 210, it can deform and shrink, thereby ensuring a tight contact and preventing damage to the pins, thus ensuring application reliability.

[0029] To further improve the forming stability of the pin within the fixing block 300, combined with Figure 4 and Figure 5 As shown, the electrical connector also includes a rear bend 603, which extends from one end of the burning section 601 into the fixing block 300 and is distributed in a bent manner within the fixing block 300, and is capable of electrically connecting the burning section 601 and the extension 605. The electrical connector also includes a front bend 602, which extends from the other end of the burning section 601 into the fixing block 300.

[0030] Specifically, the pin in this embodiment includes, in sequence, an embedded front bend 602, a horizontally exposed programming section 601, an embedded rear bend 603, an exposed inclined section 604, and an extension 605. The rear bend 603 can be bent multiple times within the fixing block 300, allowing the entire pin to exhibit an S-shaped trajectory, thus ensuring sufficient positioning and fixation with the fixing block 300, resulting in stronger structural strength and stability. Furthermore, the end of the extension 605 can be provided with a tapered chamfer to facilitate the installation guidance of the pin and the programming hole on the control board 210. The specific length of the extension 605 can be determined according to actual needs.

[0031] Furthermore, combining Figure 6 and Figure 7 As shown, to ensure stable installation of the fixing block 300, a protruding ring 311 can be provided around the four sides of the fixing block 300. Correspondingly, a limiting part 111 is provided around the inner wall of the mounting hole 110 of the cover 100. The protruding ring 311 can be supported on the limiting part 111 to achieve stable support and limitation. Furthermore, a certain space is formed between the upper peripheral area of ​​the fixing block 300 and the protruding ring 311, allowing for the installation of a sealing part 320. Specifically, a sealing ring can be provided to seal the fixing block 300 inside the cover 100. The sealing ring and the inner wall of the mounting hole 110 can be press-fitted to prevent external moisture or dust from entering.

[0032] This embodiment designs a separate programming block module, which can be flexibly assembled onto the cover 100 of the control box and can be electrically connected to the control board 210. This effectively reduces the complexity of the programming operation, allowing programming to be performed directly without repeatedly disassembling and reassembling the cover 100. This avoids adverse effects on the internal structure of the control box, improves the forming quality and stability of the pins inside the programming block, and also helps to ensure the reliability of programming.

Thanks to the teachings of this invention, those skilled in the art will readily recognize that alternative structures to the structures disclosed herein can be used as feasible alternative implementations, and that the implementations disclosed herein can be combined to produce new implementations, which also fall within the scope of the appended claims.
