Description

Technical Field

[0001] This invention relates to the field of power-on testing technology for data center computer rooms, and in particular to a dummy load device for power-on testing of data center computer rooms. Background Technology

[0002] Power-on testing in data center server rooms allows for observation of server startup time, operating speed, and heat dissipation, thus identifying potential hardware issues such as unstable power supply or poor heat dissipation. These problems can cause server crashes during operation; power-on testing enables timely detection and resolution of these issues, ensuring stable server operation.

[0003] In addition, power-on testing can verify the correctness of the server's software configuration, including operating system startup parameters, network configuration, and service settings. If problems are found during power-on and power-off processes, they can be adjusted and repaired in a timely manner to ensure the server operates as expected. Regular power-on testing can prevent sudden server failures. By conducting power-on and power-off tests, potential problems such as unstable power supply and poor heat dissipation can be identified. Addressing these issues promptly can prevent the server from suddenly crashing during operation.

[0004] Data center dummy load, also known as data center simulated load or server simulated load, is a tool used to test the performance of data center equipment, networks, and systems.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0032] The following is combined with Figures 1-7 The dummy load device for power-on testing of data center computer rooms described in this invention includes a load housing 100, electrical components, a first cabling assembly 200, and a second cabling assembly 300.

[0033] Specifically, refer to Figures 1 to 3 In this embodiment, the load housing 100 is provided with a chamber 110. At least one side of the chamber 110 is provided with a cable tray 111 that communicates with its interior. Electrical components are installed inside the chamber 110. A first cable tray assembly 200 is provided in the load housing 100. The first cable tray assembly 200 is located outside the chamber 110 and is used to arrange the wires outside the chamber 110. A second cable tray assembly 300 is provided in the load housing 100. The second cable tray assembly 300 is located inside the chamber 110 and is used to arrange the wires inside the chamber 110. The cable tray 111 is arranged correspondingly to the cable tray area of ​​the second cable tray assembly 300.

[0034] The dummy load device for power-on testing of data center computer rooms provided by the present invention has a first cable group and a second cable assembly 300. The first cable assembly 200 is used to arrange the wires connected to the dummy load device outside the chamber 110 of the load housing 100 in an orderly manner to avoid the phenomenon of wires crossing each other. The second cable assembly 300 arranges the wires connected to the dummy load device inside the chamber 110 of the load housing 100 in an orderly manner, thereby ensuring the normal use of the dummy load device.

[0035] The internal and external wires are organized by independent components (first wiring assembly 200 / second wiring assembly 300), with physical isolation to reduce mutual interference; the wiring port 111 is arranged correspondingly to the internal wiring area to ensure that the wires are clearly and orderly threaded from the outside to the inside, eliminating random tangling; the first wiring assembly 200 and the second wiring assembly 300 forcibly constrain the wire routing, replacing manual random connections and eliminating the risk of cross-stacking from the source; the wires are neatly arranged and have stable contact, reducing the probability of failure caused by cross friction or short circuits; the clear structural design simplifies the wiring process, reduces installation time and misoperation; the orderly wiring facilitates subsequent inspection, maintenance or adjustment, and extends the service life of the device.

[0036] It should be noted that the aforementioned load housing 100 is detachably connected by a housing and a cover plate, and the chamber 110 is a sealed space.

[0037] Understandably, referring to Figures 1 to 4 In some examples of the present invention, the electrical components include at least a main control chip 510 and a relay 520. The main control chip 510 is disposed in the chamber 110, the relay 520 is disposed in the chamber 110, and a resistance wire 530 is connected between the relay 520 and the main control chip 510. The load housing 100 is also equipped with a display screen 610, indicator lights 620, a start switch 630 and an emergency stop switch 640.

[0038] The main control chip 510, as the core control unit, is located in the chamber 110 and is responsible for logic processing and instruction output; the relay 520, as the execution element, is also built into the chamber 110, receives the main control signal and controls the on and off of the external circuit, and the two work together to achieve precise control.

[0039] The main control chip 510 and the relay 520 are connected by a resistor 530, which plays a role in current limiting, voltage division or protection during signal transmission, ensuring stable and reliable control signals and reducing the risk of malfunction.

[0040] The display screen 610 on the load housing 100 displays real-time equipment status information (such as operating parameters, fault prompts, etc.), the indicator light 620 provides intuitive light signal feedback on the current working mode (such as normal / abnormal), the start switch 630 is used to actively trigger the equipment to run, and the emergency stop switch 640 provides safety protection by quickly cutting off the power supply in an emergency, together improving the convenience and safety of operation.

[0041] Specifically, in this embodiment, a display screen 610 is fixedly installed in the middle of the front of the load housing 100, a main control chip 510 is fixedly installed on one side of the inner wall of the chamber 110, a relay 520 is fixedly installed on the other side of the inner wall of the chamber 110, and a resistance wire 530 is connected between the main control chip 510 and the relay 520.

[0042] It should be noted that in this embodiment, the main control chip 510 is an MCU (such as STM32F103) with ADC and PWM functions, which processes 40 relay control signals and 10 temperature sensor data in real time. The relay component 520 is a miniature solid-state relay (SSR) with a response time of <10ms and a lifespan of >100,000 cycles, ensuring high-frequency switching reliability. The resistance wire 530 is a high-power-density ceramic insulated resistance wire 530 (0.5KW / piece, withstand voltage 300VDC / 250VAC), with dimensions of... 5mm×50mm, which is convenient for dense layout.

[0043] Understandably, referring to Figure 1 , Figure 5 and Figure 6 In some examples of the present invention, the first wiring assembly 200 includes a winding group 210, a commutation group 220 and a drive assembly 230.

[0044] The winding assembly 210 is located in the load housing 100. The winding assembly 210 includes a wire guide roller 211, which is rotatable and used to wind the wire. The reversing assembly 220 is located in the load housing 100. The reversing assembly 220 includes a movable member 221, which is configured to move relative to the wire guide roller 211. The movable member 221 is provided with an adjustment part 2211, which is used to adjust the winding direction of the wire. The driving assembly 230 is used to drive the wire guide roller 211 and the movable member 221 to move synchronously.

[0045] With the above arrangement, the winding assembly 210 winds the external conductor of the chamber 110 connected to the dummy load device, and the direction of the winding conductor is adjusted by the adjustment part 2211 on the movable part 221 of the reversing assembly 220.

[0046] By using the movable part 221 and its adjusting part 2211 of the reversing group 220, the winding path and direction of the wire can be dynamically adjusted to ensure that the wire is oriented as needed during the winding process on the winding roller 211, avoiding disorder or crossing, and improving the winding quality and consistency.

[0047] The drive assembly 230 synchronously drives the wire winding roller 211 and the movable part 221, so that the wire tension adjustment (wire winding roller 211) and the direction adjustment (movable part 221) are linked and coordinated, reducing the delay or error of independent control, ensuring a smooth and stable winding process, and improving production efficiency.

[0048] The movable component 221 is integrated into the housing and directly associated with the wire guide roller 211. A single drive source enables coordinated movement of multiple components, simplifying the structure and reducing equipment size and operational complexity. The design of the adjustment unit 2211 allows for flexible changes in the wire direction based on different wire diameters and winding specifications, expanding the device's compatibility with diverse winding needs and enhancing its versatility and practicality.

[0049] It is understood that in some examples of the present invention, the reversing assembly 220 further includes two upright plates 222, a guide member 223, and a transmission member 224. The two upright plates 222 are arranged at intervals on the load housing 100. The two ends of the guide member 223 correspond one-to-one with the two upright plates 222 and are fixedly connected. The two ends of the transmission member 224 correspond one-to-one with the two upright plates 222 and are rotatably connected. The transmission member 224 is connected to the movable member 221 in a transmission manner. The movable part 221 is movably connected to the guide part 223, and the drive assembly 230 is connected to the transmission part 224. The transmission part 224 rotates and can drive the movable part 221 to reciprocate relative to the guide part 223.

[0050] With the above structure, the guide 223 provides a straight guide for the movable part 221, restricting it to move only along a preset path (left and right movement in this embodiment), avoiding deviation or shaking, thereby ensuring the precise control of the winding direction of the adjusting part 2211, and improving the consistency and reliability of the winding.

[0051] The rotation of the transmission component 224 is converted into the linear motion of the moving component 221 (such as common forms like lead screws, nuts, and connecting rods), which efficiently converts the rotational power of the drive assembly 230 into precise left and right movements. This eliminates the need for complex multi-stage transmissions and reduces energy loss and mechanical backlash.

[0052] The guide component 223 and the transmission component 224 are designed to be integrated within a limited space (such as inside the housing), eliminating the need for an additional large-sized drive mechanism. At the same time, the rotation of the transmission component 224 can directly link the moving component 221 to respond quickly, enabling real-time adjustment of the wire direction to meet dynamic winding requirements.

[0053] Both the guiding movement (guide component 223) and the rotational transmission (transmission component 224) are common forms of mechanical structures. Wear is controllable and maintenance is easy through lubrication or replacement of standard parts. The low friction characteristics of linear motion further extend the life of moving parts 221 and reduce the failure rate during long-term use.

[0054] Reference Figure 5 In this embodiment, the transmission component 224 is a transmission screw, which is threaded and connected to the movable component 221.

[0055] Specifically, the outer wall of the transmission component 224 is provided with a first threaded portion, the movable component 221 is provided with a through hole, and the inner wall of the through hole is provided with a second threaded portion. The first threaded portion and the second threaded portion are threaded and connected in a transmission manner.

[0056] The threaded drive converts the rotational motion of the transmission component 224 into the linear motion (left and right movement) of the movable component 221 by using the pitch and engagement relationship of the thread. The displacement is strictly correlated with the rotation angle of the thread (e.g., moving a distance of one pitch for each rotation). This enables precise control of the position of the movable component 221 (and the direction of the wire in the adjustment part 2211), ensuring the accuracy and repeatability of the winding direction adjustment. In addition, the above-mentioned threaded drive makes the movement of the movable component 221 more direct and the response more sensitive, while simplifying the assembly complexity of the overall dummy load device.

[0057] The forward / backward movement of the movable part 221 can be achieved by controlling the rotation direction (forward / reverse) of the transmission component 224, making the operation logic intuitive; and the thread pitch and the length of the transmission component 224 together determine the maximum adjustment stroke of the movable part 221, which makes it easy to pre-design the adjustable range according to the winding requirements and flexibly adapt to the winding requirements of different specifications of wires.

[0058] Of course, in some other examples, the transmission element 224 is a rotating crank (or rocker) that is hinged to the movable element 221 via a connecting rod, converting the rotational motion into the linear reciprocating motion of the movable element 221 (such as a crank-slider mechanism).

[0059] It should be noted that in this embodiment, the guide member 223 is a rod, i.e., a guide rod.

[0060] Understandably, referring to Figure 1 , Figure 5 and Figure 6 In some examples of the present invention, the winding assembly 210 includes two limiting plates 212, which are spaced apart on the load housing 100. The two ends of the wire feeding roller 211 correspond one-to-one with the two limiting plates 212 and are rotatably connected. The drive assembly 230 and the wire roller 211 are connected at a position that is offset from the area enclosed by the two limiting plates 212.

[0061] With the above structure, the two limiting plates 212 are arranged at intervals and serve as fixed fulcrums. The two ends of the wire laying roller 211 are rotatably connected to the limiting plates 212, forming a stable rotational support structure to ensure that the wire laying roller 211 maintains stability during the wire laying process.

[0062] The drive assembly 230 and the wire guide roller 211 are misaligned with the area enclosed by the two limiting plates 212. This prevents the drive assembly 230 (especially larger drive components or transmission structures) from directly occupying or blocking the core working area between the two limiting plates 212 (e.g., the main path of wire winding or the adjustment space of the movable part 221). This avoids mechanical interference between the drive structure and the wire, movable part 221, or other functional components. At the same time, the misaligned arrangement provides more free installation space for transmission connections (such as gears, belts, etc.), making the transmission path more direct and compact, reducing unnecessary transmission losses or additional avoidance designs, thereby improving the transmission efficiency of the driving force and the rationality of the overall structural layout. The structure is functionally rich and clear after it arrives on site, which facilitates later maintenance operations and simplifies the assembly process.

[0063] Understandably, referring to Figure 1 , Figure 5 and Figure 6In some examples of the present invention, the drive assembly 230 includes a drive pulley 231, a driven pulley 232, a transmission belt 233, and a drive member 234. The drive pulley 231 is drivenly connected to the wire guide roller 211, the driven pulley 232 is drivenly connected to the movable member 221, the transmission belt 233 is wound around the drive pulley 231 and the driven pulley 232, and the drive member 234 is drivenly connected to one of the drive pulley 231 and the wire guide roller 211 to drive its rotation. The transmission connection position between the driving pulley 231 and the wire feeding roller 211 is offset from the winding area of ​​the wire feeding roller 211, and the transmission connection position between the driven pulley 232 and the moving part 221 is offset from the movement area of ​​the moving part 221.

[0064] With the above structure, the driving component 234 drives the active pulley 231 to rotate, and the active pulley 231 drives the driven pulley 232 to rotate via the transmission belt 233, thus realizing the transmission of power. Since the active pulley 231 is connected to the winding roller 211 and the driven pulley 232 is connected to the movable component 221, the power of the driving component 234 is transmitted to the winding roller 211 and the movable component 221 respectively, so that the winding roller 211 realizes the winding action and the movable component 221 realizes the corresponding movement, thus completing the winding function. Overall, the coordinated work of the winding roller 211 and the movable component 221 is guaranteed during the winding process.

[0065] The drive pulley 231 and the winding roller 211 are offset from the winding area of ​​the winding roller 211, and the drive pulley 232 and the moving part 221 are offset from the moving area of ​​the moving part 221. This design effectively avoids interference between the drive belt 233, pulleys and the winding area or the moving area of ​​the moving part 221. During the winding process, wire will continuously wrap around in the winding area. If the drive connection point coincides with it, the drive belt 233 may rub against and wrap around the wire, affecting the winding quality and the normal operation of the equipment. Similarly, if the moving area of ​​the moving part 221 conflicts with the drive connection point, it will hinder the normal movement of the moving part 221. The offset arrangement solves these problems.

[0066] The staggered arrangement makes the spatial arrangement between the components more reasonable, which can make full use of the device space, reduce unnecessary space occupation, make the structure of the device more compact, facilitate the miniaturization design of the device, and also facilitate the installation, maintenance and repair of the device.

[0067] It should be noted that the drive component 230 described above is a belt drive structure. Of course, in some examples, a gear drive structure can also be used, which is not limited here.

[0068] In some examples, the drive assembly 230 can be integrated with other related components, such as the wire guide roller 211 and associated components of the moving part 221, to form a compact module. This integrated design can reduce the overall size and weight of the device, improve its installation convenience and stability, and also facilitate mass production and maintenance.

[0069] Alternatively, in other examples, the overall layout of the drive assembly 230 is adjustable. For instance, the positions of the drive pulley 231 and the driven pulley 232 can be adjusted via an adjustment mechanism to adapt to different working environments and wiring requirements. This adjustable layout improves the adaptability and flexibility of the device, enabling it to perform optimally in different scenarios.

[0070] In other examples, the adjustable layout may also include a tension adjustment part 2211 of the drive belt 233, which allows for easy adjustment of the tension of the drive belt 233 through simple operation, ensuring the reliability and stability of the transmission.

[0071] It should be noted that, referring to Figure 5 and Figure 6 In this embodiment, the driving component 234 is a handle. The user can directly drive the active pulley 231 to rotate by rotating the handle. The structure is simple, the cost is low, the operation is intuitive, and the controllability is strong.

[0072] Of course, in other examples, the aforementioned drive unit 234 can also be electrically driven, which is not limited here.

[0073] Understandably, referring to Figure 5 and Figure 6 In this embodiment, the height of the adjusting part 2211 is higher than the position of the wire feeding roller 211; wherein, the adjusting part 2211 is one of the wire feeding hole and the wire feeding groove.

[0074] With the above arrangement, the wire needs to be guided down from the higher adjustment section 2211 to the lower wire guide roller 211 before it is wound around the wire guide roller 211. This arrangement forms a natural falling or guiding angle, which helps the wire to transition onto the wire guide roller 211 in a more stable manner. The adjustment part 2211 is one of a cable routing hole and a cable routing groove. This means that the adjustment part 2211 plays the role of precisely constraining and orienting the cable routing. The cable routing hole can guide the cable to travel along a preset trajectory through fixed points, while the cable routing groove restricts the wire deviation through the groove structure. Both can significantly improve the cable routing effect. Before the wire contacts the wire guide roller 211, its direction is controlled by the adjustment unit 2211, so that it has a clear winding path before entering the winding stage, thereby avoiding problems such as uncertain direction, looseness or cross-linking that may occur when it directly contacts the wire guide roller 211.

[0075] Specifically, in this embodiment, the adjustment part 2211 is a cable routing hole. After the wire passes through the cable routing hole, it moves left and right through the movable part 221, so that the wire is wound orderly around the cable routing roller 211.

[0076] It should be noted that, referring to Figure 1 , Figure 5 and Figure 6 In some embodiments of the present invention, there are at least two cable holes.

[0077] Specifically, in this embodiment, there are two wiring holes arranged in this manner. It can be understood that one wiring hole is used for threading the wire, and the other wiring hole is a spare. Of course, it can also be understood that the two wiring holes correspond to different types of wires. One type of wire is threaded through each wiring hole, and then the two types of wires can be wound sequentially left and right on the same wiring roller 211. This is not limited here.

[0078] Of course, in some other examples, there may be only one cable port, which is not limited here.

[0079] More specifically, refer to Figure 1 , Figure 5 and Figure 6 In this embodiment, the movable component 221 includes a movable block 2212 and a cable tray 2213 connected to the movable block 2212. The movable block 2212 cooperates with the guide component 223 and the transmission component 224, while the cable tray 2213 has corresponding cable holes. In some examples of the present invention, the movable block 2212 and the cable tray 2213 can be fixedly connected, such as by bolts, snap-fit, etc., or the movable block 2212 and the cable tray 2213 can also be an integrally formed structure, which is not limited here.

[0080] Understandably, referring to Figure 1 , Figure 3 and Figure 7 In some examples of the present invention, the second wiring assembly 300 includes a telescopic member 310, a wiring platform 320, and a wiring wheel 330. The telescopic member 310 includes a fixed end 311 and a telescopic end 312 connected to the fixed end 311. The fixed end 311 is disposed on the load housing 100. The wiring platform 320 is fixedly connected to one end of the telescopic end 312 away from the fixed end 311. The wiring wheel 330 is rotatably connected to the wiring platform 320 and is used to arrange wires.

[0081] With the above structure, the telescopic component 310 can provide an adjustable linear displacement. When the telescopic end 312 extends or retracts, it will cause the connected structure to change position, laying the foundation for subsequent adjustment of the wiring position. This realizes the position adjustment capability of the wiring assembly in the straight line direction, so that the wiring operation can be performed at different linear positions.

[0082] The cable tray 320 can accurately reach the preset position, providing stable support and accurate positioning for the cable tray 330, ensuring that the cable laying operation can be carried out in the expected position, and improving the positional accuracy of the cable laying.

[0083] The wire guide wheel 330 is rotatably connected to the wire guide table 320. This rotatable connection allows the wire guide wheel 330 to rotate freely as the wire moves when it comes into contact with the wire. When the wire is pulled through the wire guide wheel 330, the wire guide wheel 330 does not generate excessive frictional resistance to hinder the wire's progress; instead, it uses its own rotation to coordinate with the wire's movement.

[0084] The aforementioned second wiring assembly 300 and other components can efficiently, accurately, and orderly arrange the wires, improving the quality and efficiency of wiring work.

[0085] Specifically, refer to Figure 1 , Figure 3 and Figure 7 In some examples of the present invention, the second wiring assembly 300 further includes an elastic pusher 340, one end of which abuts against the load housing 100 and the other end of which abuts against the wiring platform 320. This avoids the wires from being squeezed and deformed due to excessive pressure or the wiring from being loose due to insufficient pressure, thereby achieving adaptive constant pressure wiring and improving the tightness and consistency of the wire arrangement.

[0086] Specifically, refer to Figure 1 , Figure 3 and Figure 7 In some examples of the present invention, the second ribbon cable assembly 300 is in two sets, and the ribbon cable port 111 is one; The two sets of second wiring assemblies 300 are located on the same side of the chamber 110, and the two sets of second wiring assemblies 300 are aligned and facing each other along the height direction of the chamber 110; There is a gap between the two sets of second ribbon cable assemblies 300, and the ribbon cable port 111 is aligned with the gap between the two sets of second ribbon cable assemblies 300.

[0087] In this embodiment, the wires can enter the cavity 110 through the cable tray 111 and be electrically connected to the electrical components, or the wires connected to the electrical components inside the cavity 110 can extend out of the cavity 110 through the cable tray 111 and be electrically connected to the external device.

[0088] With the above arrangement, the wire enters the cavity 110 through the cable tray 111 or goes to the outside. The wire passes between the cable tray wheels 330 of the two sets of second cable tray assemblies 300. The cable tray wheels 330 straighten the wire, avoiding bending and folding of the wire. This ensures that the wire required for connection does not need to be too long, and that the cable tray wheels 330 can clamp the wire to complete the cable laying. The cable guide wheels 330 of the two sets of second cable guide assemblies 300 are not just simple straightening tools, but also core functional modules that integrate precise guidance, dynamic clamping, and coordinated cable guide. Through the combination of mechanical constraints and intelligent control, while ensuring that the physical state of the wires meets the connection requirements, they improve the overall assembly efficiency, material utilization, and electrical performance reliability. More specifically, refer to Figure 1 and Figure 3 In some examples of the present invention, there are two sets of first wiring assemblies 200, and the two sets of first wiring assemblies 200 are arranged at intervals outside the chamber 110. The second wiring assembly 300 consists of four sets, with two wiring ports 111. Each side wall of the chamber 110 has a wiring port 111, and two sets of second wiring assemblies 300 are provided on each side of the chamber 110 along the horizontal direction.

[0089] By adopting the above arrangement, the first cabling assembly 200 is set into two groups with intervals and arranged outside the cavity 110, forming a coordinated cabling architecture with the second cabling assembly 300. The four groups of second cabling assemblies 300 are respectively arranged in a "two-to-two symmetrical" manner on both sides of the horizontal direction of the cavity 110 (in conjunction with the two cabling ports 111 opened on opposite side walls of the cavity 110). This allows wires of different functions or specifications to be accurately matched with the corresponding cabling ports 111 according to their routing requirements. The two external groups of first cabling assemblies 200 prioritize the handling of wire bundles that need to be connected or centrally managed across the cavity 110, while the four internal groups of second cabling assemblies 300 guide the wire bundles leading out from both ends of the cavity 110 in a zoned manner. Ultimately, this achieves the orderly diversion of multiple types of wires, the shortest path, and the minimization of interference. This not only improves space utilization and wiring clarity, but also reduces the risk of signal crosstalk through physical isolation, ensuring the efficiency, maintainability, and long-term stability of the wire connection inside and outside the cavity 110.

[0090] Understandably, referring to Figures 1 to 3 In some examples of the present invention, the dummy load device further includes a connector 400, which is provided corresponding to the cable port 111 and the two are connected. The connector 400 is used to connect the wires inside the chamber 110 to the external device. The connector 400 is a hollow cylinder, and / or the connector 400 has an elastic structure inside; wherein, when the connector 400 has an elastic structure inside, the elastic structure is used to avoid the wire when the wire moves, and to clamp and position the wire when the wire is fixed.

[0091] With the above arrangement, a connecting connector 400 connected to the cable tray 111 is provided, which not only achieves a reliable connection between the wires inside the chamber 110 and the external device, but also significantly improves the stability and ease of operation of the wire connection by designing the connecting connector 400 as a hollow cylindrical structure and / or incorporating an elastic structure inside. When the hollow cylindrical structure provides a smooth passage for the wires, the internal elastic structure can flexibly avoid mechanical damage to the wires during insertion or movement. At the same time, after the wires are fixed in place, the elastic structure can automatically clamp and position the wires to prevent them from loosening or shaking, thereby ensuring the reliability of electrical signal transmission and the durability of long-term use.

[0092] The above not only simplifies the assembly process and enhances the practicality and adaptability of the device, but also provides convenient operating conditions for subsequent maintenance and wire replacement, effectively improving the overall connection performance, safety of use, and system integration of the device.

[0093] It should be noted that in some examples, the above-mentioned elastic structure can be an elastic rubber ring, an elastic clip, or a helical spring. The connector 400 is provided with a helical spring with a guide hole inside. The wire passes through the central hole of the helical spring, and the spring can extend and retract according to the direction of the wire's movement. When the wire is inserted, the spring is compressed or stretched to provide clearance for the wire's movement. When the wire stops moving, the spring slightly holds the wire with its own elastic force to play an auxiliary positioning role.

[0094] It is understood that in some examples of the present invention, the two sets of first wiring assemblies 200 respectively wire different conductors, while the two sets of second wiring assemblies 300 at the same end straighten and wire the same conductor. Of course, other coordination methods can also be adopted in practical applications. For example, the two sets of second wiring assemblies 300 at the same end can first wire the same conductor and then one of the sets of first wiring assemblies 200 can perform subsequent wiring processing, or the first wiring assembly 200 can first wire the conductor and then the second wiring assembly 300 can straighten and wire the conductor, that is, to achieve the coordinated cooperation of one set of first wiring assemblies 200 and two sets of second wiring assemblies 300. Alternatively, one set of first wiring assemblies 200 and two sets of second wiring assemblies 300 can be used together to wire the same conductor. In this case, the conductor can extend from the inside of the chamber 110 outward or extend from the inside of the chamber 110 outward. The specific path can be flexibly adjusted according to actual needs without limitation.

[0095] The following is an example of the working process of the present invention: The user turns the handle, which drives the wire guide roller 211 to rotate. The wire guide roller 211 winds the wire connected to the dummy load device in an orderly manner, and the drive pulley 231 on the wire guide roller 211 moves synchronously. The drive pulley 231 drives the driven pulley to rotate through the connecting belt. The driven pulley 232 drives the transmission component 224 (lead screw structure) to rotate. The first thread on the surface of the transmission component 224 matches the second thread on the inner wall of the movable block 2212 of the movable component 221. The movable block 2212 is limited by the movable rod, so the movable block 2212 slides along the lead screw, adjusting the position of the wire guide plate 2213. The wire guide hole adjusts the direction of the wound wire.

[0096] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
