Description

Technical Field

[0001] This invention relates to the field of controller technology, specifically a digital electric actuator controller. Background Technology

[0002] The electric actuator controller is the core control unit of the electric actuator, essentially an intelligent control module integrating "signal reception, logic operation, drive output, status feedback, and fault protection." Its core function is to receive external control commands (such as digital signals, analog signals, and bus signals), drive the motor of the electric actuator, and thus control the opening or switching status of terminal actuators such as valves, baffles, and other valve components. Simultaneously, it monitors the operating status in real time and feeds it back to the host system to ensure the actuator operates accurately, stably, and safely. Furthermore, a crucial step in using the electric actuator controller is wiring it. The wiring compartment of the electric actuator controller is a sealed cavity specifically designed to accommodate and protect electrical wiring and terminals. Its core function is to realize the electrical connection between the controller and external equipment (host system, power supply, sensor, actuator motor), while providing dustproof, waterproof and electric shock protection functions. It is the "physical interface hub" for the controller to interface with external systems. However, when wiring the electric actuator control, it is usually necessary to disassemble its wiring cavity 31 and then insert the wire core of the cable. This process is relatively complicated, and if the disassembly of the wiring cavity 31 is not done properly, it can easily reduce its sealing performance and thus affect its service life.

[0003] In summary, to address the technical problems raised in this paper, this invention proposes a digital electric actuator controller. Summary of the Invention

[0004] To address the aforementioned problem that existing wiring methods for electric actuators typically require disassembling the wiring cavity 31 and then inserting the cable cores, a process that is complex and prone to compromised sealing and lifespan if not handled properly during disassembly, this invention proposes a digital electric actuator controller. This controller includes a controller body, a heat dissipation end, and wiring terminals. The heat dissipation end is located on one side of the controller body, and the wiring terminals are located on the upper part of the controller body. The wiring terminals are characterized by: The wiring cavity is located at the upper end of the controller body; The wiring hole is located on the side of the controller body and is connected to the inside of the wiring cavity. The groove is formed on both inner walls of the wiring cavity; There are two limiting plates, and the two ends of the two limiting plates are slidably connected to the inside of the sliding grooves on both sides of the wiring cavity; and the two limiting plates are connected to the springs set inside the sliding grooves. The mounting slot is located at the top of the controller body; The mounting plate is slidably connected inside the mounting groove, and a sealing plate is provided at the upper end of the mounting plate; a conductive layer is laid on the outer ring of the mounting plate. A locking assembly; it is located inside the wiring cavity and is used to lock the locking plate.

[0005] As a preferred embodiment of this application, the locking component includes... The support plate is slidably connected to the bottom of the wiring cavity, and the width of the support plate is greater than the gap between the two limiting plates. In the initial state, the support plate is located between the two limiting plates, and the upper end of the support plate is on the same horizontal plane as the upper ends of the two limiting plates. The upper end of the support plate is arc-shaped, and the lower ends of the two limiting plates are arc-shaped.

[0006] As a preferred embodiment of this application, the locking component further includes, A metal sheet is fixed between two limiting plates, and in the initial state, the gap between the two limiting plates is greater than the width of the mounting plate; when the mounting plate moves downward, the lower end of the mounting plate squeezes the metal sheet.

[0007] As a preferred embodiment of this application, each limiting plate has a hinge groove at its upper end, the hinge groove is located at the end of the two limiting plates that are close to each other, and a hinge plate is hinged inside the hinge groove.

[0008] As a preferred embodiment of this application, a rectangular groove is formed at the ends of the two limiting plates that are far apart from each other, and multiple extrusion grooves are formed at the ends of the two limiting plates that are close to each other. An adjustment groove is formed on the lower inner wall of the rectangular groove, and the adjustment groove communicates with the rectangular groove. A rectangular plate is slidably connected to the inside of the rectangular groove by a spring. A rectangular block is set at the lower end of the rectangular plate, and the rectangular block is located inside the adjustment groove. Multiple extrusion blocks are set at the upper end of the rectangular plate, and the extrusion groove is slidably connected to the inside of the extrusion block. In the initial state, the two side walls of the support plate extrude the rectangular block, so that the extrusion block is located inside the extrusion groove. Multiple grooves are formed on the side wall of the mounting plate, and the grooves correspond to the extrusion grooves. Rectangular notches are formed on both sides of the lower end of the mounting plate.

[0009] As a preferred embodiment of this application, an elastic element is provided inside the groove, and the elastic element is an elastic contraction element.

[0010] As a preferred embodiment of this application, the elastic element is a telescopic spring. The beneficial effects of this invention are as follows: The support plate moves downwards synchronously between the two limiting plates, and at the same time, the cable core bends, causing the cable to form a U-shape. During this process, the cable is inserted from the wiring hole into the wiring cavity. Once the support plate moves downwards and completely disengages from the gap between the two limiting plates, the two limiting plates are no longer supported by the support plate. The ends of the two limiting plates are then influenced by the springs inside the slide groove, causing the two limiting plates to move closer together inside the slide groove. This pressures the two limiting plates against the central mounting plate, causing the bent cable cores on both sides of the mounting plate to adhere tightly to the conductive layer surface on both sides of the mounting plate. This enables the cable cores to conduct electricity, and the cable simultaneously forms a U-shape. This allows for the fixing of the cable cores without disassembling the controller body, improving installation efficiency. Attached Figure Description

Detailed Implementation

[0012] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0013] Example 1: like Figures 1 to 10 As shown; a digital electric actuator controller, the controller includes a controller body 1, a heat dissipation end 2, and a wiring terminal 3; the heat dissipation end 2 is located on one side of the controller body 1, and the wiring terminal 3 is located on the upper end of the controller body 1; the wiring terminal 3 includes: Wiring cavity 31 is located at the upper end of controller body 1; Wiring hole 32 is provided on the side of controller body 1 and is connected to the inside of wiring cavity 31; The groove 33 is formed on both inner walls of the wiring cavity 31; There are two limiting plates 34, and the two ends of the two limiting plates 34 are slidably connected to the inside of the sliding grooves 33 on both sides of the wiring cavity 31; and the two limiting plates 34 are connected to the springs provided inside the sliding grooves 33. Mounting slot 35 is located at the top of controller body 1; Mounting plate 36 is slidably connected inside mounting groove 35, and a sealing plate 361 is provided at the upper end of mounting plate 36; a conductive layer is laid on the outer ring of mounting plate 36. Locking assembly 4; it is disposed inside the wiring cavity 31 and is used to lock the locking plate; Locking component 4 includes, The support plate 41 is slidably connected to the bottom of the wiring cavity 31, and the width of the support plate 41 is greater than the gap between the two limiting plates 34. In the initial state, the support plate 41 is located between the two limiting plates 34, and the upper end of the support plate 41 is on the same horizontal plane as the upper end of the two limiting plates 34. The upper end of the support plate 41 is arc-shaped, and the lower end of the two limiting plates 34 is arc-shaped. The specific workflow is as follows; The operator inserts the cable core into the wiring cavity 31 through the wiring hole 32. After insertion, the cable core is positioned above the two limiting plates 34 and below the mounting plate 36. Once the cable core is installed, the operator presses down on the sealing plate 361 at the top of the mounting plate 36. The sealing plate 361 is the same size as the top of the controller body 1. As the sealing plate 361 is pressed down, it causes the mounting plate 36 below it to move downwards synchronously. The mounting plate 36 moves downwards within the mounting groove 35. During this process, the lower end of the mounting plate 36 presses down on the cable core. As the mounting plate 36 moves downwards, it presses down on the cable core and, in turn, presses down on the support plate 41 in the locking assembly 4, causing the support plate 41 to be positioned at the two limiting plates. The plates 34 move downwards synchronously, and at the same time, the cable core bends, causing the cable to bend in a U-shape. During this process, the cable is inserted from the wiring hole 32 into the wiring cavity 31. Until the support plate 41 moves downwards and completely disengages from the gap between the two limiting plates 34, the two limiting plates 34 are no longer supported by the support plate 41. The two ends of the two limiting plates 34 are affected by the spring inside the slide groove 33, and the two limiting plates 34 move closer to each other inside the slide groove 33. This causes the two limiting plates 34 to press against the central mounting plate 36, so that the cable core bent on both sides of the mounting plate 36 is tightly attached to the conductive layer surface on both sides of the mounting plate 36. This makes the cable core conductive. At the same time, the cable bends in a U-shape, thereby achieving the fixation of the cable core without disassembling the controller body 1, improving installation efficiency. Furthermore, during maintenance of the controller body 1 and during installation, the mounting plate 36 slides within the mounting groove 35, causing the groove wall of the mounting groove 35 to rub against the side wall of the mounting plate 36. This rubs against the conductive layers on both sides of the mounting plate 36, preventing the formation of a metal oxide layer on the conductive layers during prolonged use and thus avoiding the impact of the metal oxide layer on the conductive layers on the conductive layers. After the cable core is removed, the mounting plate 36 and the sealing plate 361 are lifted upwards. During this process, the mounting plate 36 no longer presses against the support plate 41, causing the spring at the lower end of the support plate 41 to elastically reset. The support plate 41 moves upwards, and the arc-shaped end at the upper end of the support plate 41 embeds between the two limiting plates 34, widening the gap between the two limiting plates 34 and pushing the cable upwards, facilitating the cable's disengagement from between the two limiting plates 34 and making it easier to install the cable next time.

[0014] Example 2: like Figure 2As shown; the difference between this embodiment and the above embodiment is that this embodiment is a supplementary description of the locking component 4 in the first embodiment above. Specifically, this embodiment can be used as a parallel embodiment of the locking component 4 in the first embodiment. Locking component 4 also includes, The metal sheet 42 is fixed between two limiting plates 34, and in the initial state, the gap between the two limiting plates 34 is greater than the width of the mounting plate 36; when the mounting plate 36 moves downward, the lower end of the mounting plate 36 squeezes the metal sheet 42.

[0015] The specific workflow is as follows; Unlike Embodiment 1 described above, when the mounting plate 36 moves downward, its lower end does not press against the support plate 41. Instead, the mounting plate 36 directly pushes the cable downward until its lower end contacts the metal sheet 42 between the two limiting plates 34. After being pressed, the metal sheet 42's center is concave downward, causing it to pull the two limiting plates 34 closer together. This results in the two limiting plates 34 pressing against the conductive layers on both sides of the mounting plate 36, tightly adhering the cable core to the conductive layer. This allows for cable installation without disassembling the controller body 1.

[0016] Example 3: like Figures 1 to 10 As shown; each limiting plate 34 has a hinge groove 37 at its upper end. The hinge groove 37 is located at the end of the two limiting plates 34 that are close to each other. A hinge plate 371 is hinged inside the hinge groove 37. The specific workflow is as follows; Based on the above embodiment 1; when the support plate 41 is located between the two limiting plates 34, the side walls of the two limiting plates 34 support the hinge plate 371 inside the hinge groove 37, preventing the hinge plate 371 from bending; when the mounting plate 36 moves downward, the mounting plate 36 simultaneously presses against the support plate 41; and because the support plate 41 and the mounting plate 36 press against each other and move downward at the same time, when the mounting plate 36 just enters between the two limiting plates 34, the support plate 41 has just slid downward from between the two limiting plates 34, and the two sides of the support plate 41 are still in a state of limiting the hinge plate 371, thereby allowing the mounting plate 36 to... The device smoothly enters the gap between the two limiting plates 34. As the mounting plate 36 continues to move downward, the support plate 41 no longer limits the two hinge plates 371, causing the two hinge plates 371 to bend towards the center. This allows the ends of the hinge plates 371 to contact the conductive layer on the side wall of the mounting plate 36. As the mounting plate 36 moves downward, the hinge plates 371 will squeeze the wire cores of the cables on both sides of the mounting plate 36, pressing the wire cores tightly against the conductive layer. At the same time, as the mounting plate 36 continues to move downward, the hinge plates 371 scrape the cables on the surface of the conductive layer to prevent the formation of a metal oxide layer on the wire cores, which would increase resistance.

[0017] Example 4: like Figures 1 to 10 As shown; rectangular grooves 38 are formed at the ends of the two limiting plates 34 that are far apart from each other, and multiple extrusion grooves 381 are formed at the ends of the two limiting plates 34 that are close to each other. An adjustment groove 382 is formed on the lower inner wall of the rectangular groove 38, and the adjustment groove 382 communicates with the rectangular groove 38; a rectangular plate 383 is slidably connected to the inside of the rectangular groove 38 by a spring, and a rectangular block 384 is set at the lower end of the rectangular plate 383, and the rectangular block 384 is located inside the adjustment groove 382; multiple extrusion blocks 385 are set at the upper end of the rectangular plate 383, and the extrusion grooves 381 are slidably connected to the extrusion blocks 385; in the initial state, the two side walls of the support plate 41 press against the rectangular block 384, so that the extrusion block 385 is located inside the extrusion groove 381; multiple grooves 39 are formed on the side walls of the mounting plate 36, and the grooves 39 correspond to the extrusion grooves 381; rectangular notches 362 are formed on both sides of the lower end of the mounting plate 36. An elastic element 391 is provided inside the groove 39; the elastic element 391 is an elastic contraction element. Elastic element 391 is a telescopic spring; The specific workflow is as follows; Based on Embodiments 1 and 3 above, in the initial state, the two sides of the support plate 41 press against the rectangular block 384, causing the pressing block 385, the rectangular plate 383, and the pressing block 385 to be located inside the rectangular groove 38. Based on this, when the mounting plate 36 moves downwards, the mounting plate 36 pushes the support plate 41 downwards until the support plate 41 no longer supports the two limiting plates 34. At this point, the support plate 41 no longer presses against the rectangular block 384, causing the two limiting plates 34 to move synchronously towards the center. The inner rectangular plates 383 approach each other, causing the rectangular blocks 384 on the lower side of the two rectangular plates 383 to extend out from the inside of the adjustment groove 382, ​​so that the adjustment groove 382 extends into the inside of the rectangular notch 362 on the lower side of the mounting plate 36, and the pressing block 385 extends out from the inside of the pressing groove 381, so that the pressing block 385 extends into the inside of the groove 39, thereby realizing the simultaneous pushing of the bent cable core into the groove 39 and the rectangular notch 362, so that the cable core is subjected to multiple bending and pressing, thereby improving the stability of the cable core; When removing the cable, the mounting plate 36 and the sealing plate 361 are lifted upwards. During this process, since the size of the groove 39 is larger than that of the pressing block 385, when the mounting plate 36 moves upwards, the support plate 41 moves upwards at the same time. In the early stage of the movement, the pressing block 385 will first move downwards inside the groove 39 until the ends of the rectangular blocks 384 on both sides of the support plate 41 are pressed, so that the rectangular blocks 384 are retracted into the adjustment groove 382, ​​and the pressing block 385 is simultaneously detached from the groove 39.

[0018] Based on the above embodiments, when the extrusion block 385 enters the interior of the groove 39, the extrusion block 385 extrudes the cable, causing the cable core to enter the interior of the groove 39. At the same time, the extrusion block 385 extrudes the elastic element 391 inside the groove 39. The elastic element 391 is a telescopic spring, causing the elastic element 391 to be compressed and contracted. Since the elastic element is a telescopic spring, after the spring contracts, it will swing, preventing the cable core from bending flat, thereby improving the roughness of the cable core and thus improving the stability of the cable core. Furthermore, once the pressing block 385 disengages from the inside of the groove 39, the elastic element 391 inside the groove 39 pushes the cable core out of the groove 39, making it easy to remove.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
