Description

Technical Field

[0001] This utility model relates to the field of pump unit technology, and more specifically, to a control box output adapter structure for a pump and a pump. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. Typically, a pump set includes a base and a control box. The base houses the drive motor, and the control box contains an electrical control board connected to the motor to control its operation. The control box also needs an interface for connecting power or signal cables from the client. The client sends control signals or supplies power to the control box to instruct the drive motor to operate. During installation of the client and the pump, the pins corresponding to the signal and power cables must be inserted together into the corresponding interfaces on the control box.

[0003] In practice, pumps typically operate in confined spaces. The design of the outlet interface not only affects the size control of the control box but also increases the difficulty of wiring installation when space is limited. This makes it inconvenient to plug and unplug the interface lines, reducing the adaptability to demanding environments. Furthermore, precise size control increases processing difficulty and production costs. Therefore, it is meaningful to balance the convenience of production and application.

[0004] A search revealed that patent CN111668674A provides a pump output adapter module, in which an adapter component is integrally formed on the second connection part. One end of the adapter component is used to connect to a wiring plug, and the other end is used to connect to an electrical contact point on the pump's control module. This simplifies the connection method between the adapter component and the control module and improves the accuracy of the connection between the adapter component and the electrical contact point. Patent CN219892532U provides an output adapter structure and a pump. The pump's control box has a control plug-in part, and the driver connection part plugs into the control plug-in part for electrical connection with the driver. A grounding pin is located between the signal pin and the power pin; the signal line interface and the power line interface are located on both sides or below the control plug-in part, respectively. Both of these designs involve structural adjustments to the output adapter, but there is still room for further optimization. Utility Model Content

[0005] 1. Technical problem to be solved by the utility model

[0006] To address the issues of insufficient space and inconvenient installation associated with existing control box wiring adapters, this paper proposes a control box wiring adapter structure and pump for pumps, which will help optimize installation and operation convenience and reduce manufacturing difficulty.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0009] This utility model discloses a pump control box outgoing wiring adapter structure, comprising:

[0010] The outer perimeter of the box base includes a first sidewall and a second sidewall located on different sides and distributed adjacently. The end of the first sidewall near the second sidewall is recessed towards the inside of the box base to form a concave wall surface. The concave wall surface extends to connect with the end of the second sidewall, so that the extension direction P of the first sidewall and the extension direction N of the second sidewall intersect and enclose to form an external interface area.

[0011] An external connector includes a support frame with an external interface on the support frame, wherein at least two-thirds of the volume of the external connector is located within the external interface area.

[0012] Furthermore, the external interfaces on the support frame include signal line interfaces and power interfaces, which are distributed sequentially along the length of the support frame.

[0013] Furthermore, along the extending direction P of the first sidewall, the outer wall of the support frame remains flush with the first sidewall; along the extending direction N of the second sidewall, the outer wall of the support frame remains flush with the second sidewall; the inner side of the support frame extends to connect with the concave wall surface.

[0014] Furthermore, the bottom surface of the support frame is close to the bottom wall of the box base, and the top surface of the support frame is lower than the height of the box cover on the top surface of the box base. The external interface extends on the support frame toward the box cover, and its height is lower than that of the box cover.

[0015] Furthermore, the support frame and the housing are either integrally formed or separately connected; the signal line interface and power interface are integrally formed on the support frame.

[0016] Furthermore, the signal line interface includes a signal pin and a signal protective cover. One end of the signal pin extends to connect with the electronic control board inside the housing, and the other end extends outside the housing and is covered by the signal protective cover. The power interface includes a power pin and a power protective cover. One end of the power pin extends to connect with the electronic control board inside the housing, and the other end extends outside the housing and is covered by the power protective cover. Both the signal protective cover and the power protective cover are set close to the outer side of the support frame and have a gap between them and the concave wall surface.

[0017] Furthermore, the top surface of the support frame has a downwardly recessed upper slot located between the power supply protective cover and the concave wall surface. The upper slot extends from the outer wall of the power supply protective cover to the concave wall surface, and the bottom surface of the upper slot seals and covers the internal power pins. The same upper slot is provided between the signal protective cover and the concave wall surface.

[0018] Furthermore, the bottom surface of the support frame has multiple inwardly recessed lower slots along the length direction, with connecting ribs separating adjacent lower slots, and the bottom surface of the lower slots sealing and covering the internal power pins and signal pins.

[0019] Furthermore, the end where the concave wall meets the first side wall is provided with an inclined guide wall; or / and, the support frame is provided with a drainage groove that extends through the thickness direction.

[0020] This utility model also provides a pump that adopts the control box outgoing wire adapter structure as described above, with the bottom of the control box connected to a base.

[0021] 3. Beneficial effects

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

[0023] (1) The outgoing wire adapter structure of this utility model forms an external interface area outside the box base, so that the signal wire interface and power interface are set outside the box base and fixedly installed by the support frame. This can effectively reduce the manufacturing difficulty and the installation positioning difficulty, ensure the size and installation accuracy of the signal wire interface and power interface, and avoid interference or excessive gap during plug insertion. It can better meet the user's needs.

[0024] (2) In the cable transfer structure of this utility model, the bottom surface of the support frame is close to the bottom wall of the box base. The external interface extends on the support frame toward the box cover and is lower than the box cover. It has enough space for the signal line interface and power interface to extend upward, which makes it easy for the external line to be directly inserted and connected along the height of the box base. The insertion position is hidden within the height range of the box base. This not only saves the overall volume, but also, in practice, the signal line interface and power interface are generally distributed downwards during installation and application. The box base can also form an effective protection for the interface position, avoiding leakage and water ingress that may affect the safety and stability of use. Attached Figure Description

[0037] The present invention will be further described below with reference to the embodiments.

[0038] Example

[0039] Combination Figures 1-5As shown, this embodiment provides a pump, including a control box 100 and a base 300 that are fitted together. The electrical control board inside the control box 100 is electrically connected to the motor assembly inside the base 300. The control box 100 includes a box base 110 and a box cover 120. The box base 110 is provided with a cable outlet adapter structure. Specifically, the outer four-sided wall of the box base 110 includes a first side wall 111 and a second side wall 112 located on different sides and adjacent to each other. The end of the first side wall 111 near the second side wall 112 faces... The inner side of the housing 110 is recessed to form a concave wall 113, which extends to connect with the end of the second sidewall 112, such that the extension direction P of the first sidewall 111 and the extension direction N of the second sidewall 112 intersect and enclose to form an external interface area 200. An external connector is provided within this external interface area 200, specifically including a support frame 210. The support frame 210 has an external interface, and at least two-thirds of the volume of the external connector is located within this external interface area 200. Specifically, the external interface on the support frame 210 includes a signal line interface 220 and a power interface 230, which are sequentially distributed along the length of the support frame 210. The power interface 230 is used to connect to an external power source, and the signal line interface 220 is used to connect to an external signal line. The support frame 210, signal line interface 220, and power interface 230 can be completely located within the external interface area 200, or their outer edges can slightly extend beyond the external interface area 200. Overall, they remain consistent with the structural shape of the box 110, without taking up too much extra space, maintaining the overall compact spatial distribution of the box 110, and making them more adaptable to the installation environment.

[0040] In this embodiment, through the above-described configuration, an external interface area 200 is formed outside the housing 110, thereby placing the signal cable interface 220 and the power interface 230 outside the housing 110 and fixing them in place using the support frame 210. In practice, the signal cable interface 220 and the power interface 230 are integrally formed on the support frame 210, which is either integrally formed with the housing 110 or separately connected. Placing the signal cable interface 220 and the power interface 230 outside the side wall of the housing 110 effectively reduces manufacturing difficulty. Furthermore, fixing the interfaces with the support frame 210 further reduces installation and positioning difficulty, ensuring the size and installation accuracy of the signal cable interface 220 and the power interface 230, and avoiding interference or excessive gaps during plug insertion, thus better meeting user needs.

[0041] Combination Figure 2As shown, preferably, along the extending direction P of the first sidewall 111, the outer wall of the support frame 210 is flush with the first sidewall 111; along the extending direction N of the second sidewall 112, the outer wall of the support frame 210 is flush with the second sidewall 112. In this embodiment, "flush" means basically flush, which can be completely flush with the sidewall plane, or it can have a slight difference, but basically maintains a smooth transition connection between the outer wall of the support frame 210 and the outer walls on both sides of the box base 110. The inner side of the support frame 210 extends to connect with the concave wall surface 113. That is, the support frame 210 completely covers the outer interface area 200 formed by the intersection of the extending direction P of the first sidewall 111 and the extending direction N of the second sidewall 112, maintaining the consistency of the overall shape structure of the box base 110. Furthermore, the bottom surface of the support frame 210 is close to the bottom wall of the box base 110, and the height of the top surface of the support frame 210 is lower than the height of the box cover 120 on the top surface of the box base 110. The external interface extends on the support frame 210 toward the box cover 120, and the height of both interfaces is lower than that of the box cover 120. Along the height direction of the housing 110, the support frame 210 is positioned lower, providing ample space between it and the housing cover 120 for the signal line interface 220 and the power interface 230 to extend upwards. Both the signal line interface 220 and the power interface 230 extend upwards along the height direction of the housing 110 without exceeding its height. This facilitates direct insertion and connection of external cables along the height direction of the housing 110, with the insertion points concealed within the height range of the housing 110. This not only saves on overall volume but also, in practical applications, the signal line interface 220 and the power interface 230 are typically positioned downwards. The housing 110 effectively protects the interface locations, preventing leakage and water ingress that could affect safety and stability.

[0042] Specifically, the signal line interface 220 includes a signal pin 221 and a signal protective cover 222. One end of the signal pin 221 extends to connect with the electronic control board inside the housing 110, and the other end extends outside the housing 110, covered by the signal protective cover 222. The power interface 230 includes a power pin 231 and a power protective cover 232. One end of the power pin 231 extends to connect with the electronic control board inside the housing 110, and the other end extends outside the housing 110, covered by the power protective cover 232. Both the signal protective cover 222 and the power protective cover 232 are positioned close to the outer side of the support frame 210, with a gap between them and the concave wall surface 113. The protective cover effectively protects the pin, and its outer positioning, while maintaining a gap with the concave wall surface 113, also provides sufficient insertion space, facilitating cable insertion.

[0043] Furthermore, combining Figure 4As shown, the top surface of the support frame 210 has a downwardly recessed upper slot 211 located between the power supply shield 232 and the concave wall surface 113. The upper slot 211 extends from the outer wall of the power supply shield 232 to the concave wall surface 113, and the bottom surface of the upper slot 211 seals and covers the internal power pin 231. The signal shield 222 has the same upper slot 211 between it and the concave wall surface 113. The support frame 210 seals and wraps the portions of the power pin 231 and the signal pin 221 that extend out of the housing 110. The upper slot 211 is more conducive to ensuring the molding quality of the support frame 210. In practice, the power supply shield 232, the signal shield 222, the support frame 210, and the housing 110 are preferably integrally injection molded. The upper slot 211 does not affect the sealing of the internal pins and can also improve the injection molding quality.

[0044] Furthermore, combining Figure 5 As shown, the bottom surface of the support frame 210 has multiple inwardly recessed lower slots 212 along its length. Connecting ribs 213 separate adjacent lower slots 212. The bottom surface of the lower slots 212 seals and covers the internal power pins 231 and signal pins 221. Similarly, the lower slots 212 do not affect the sealing of the internal pins and also help improve the injection molding quality. The connecting ribs 213 also form reinforcing ribs, which help improve the structural strength.

[0045] Furthermore, combining Figure 2 As shown, the end where the concave wall 113 meets the first side wall 111 is provided with an inclined guide wall, which not only achieves a smooth transition of the mating surface but also forms a drainage guide surface. Even if the first side wall 111 is mistakenly facing upwards during installation, rainwater can be quickly discharged through the inclined guide wall, reducing the seepage into the signal protection cover 222 and the power protection cover 232. Furthermore, the support frame 210 can also be provided with a drainage groove that extends through the thickness direction. Specifically, in the area outside the upper slot 211 that is not where the pin is located, a drainage groove that extends through the thickness can be opened. Even if some water appears on the support frame 210, it can help to drain, preventing water from entering the signal protection cover 222 and the power protection cover 232, ensuring stability and safety during use.

[0046] The scope of protection of this utility model is defined only by the claims. Thanks to the teachings of this utility model, those skilled in the art will readily recognize that alternative structures to the disclosed structure can be used as feasible alternative implementations, and that the disclosed implementations can be combined to produce new implementations, which also fall within the scope of the appended claims.
