Description

Technical Field

[0001] The present application relates to the technical field of electrical connection equipment, and in particular to a wiring device. Background Art

[0002] In modern electrical systems and electronic equipment, wiring devices, as crucial components for electrical connections, are widely used in control cabinets, distribution boxes, industrial automation equipment, inverters, PLC systems, and other electrical equipment. The primary function of wiring devices is to establish an electrical connection between external engineering circuits and the internal motherboard of the equipment, ensuring reliable transmission of electrical signals.

[0003] Traditional wiring devices typically utilize a fixed connection structure, where the relative positions of the engineering terminal and the motherboard terminal are determined during product manufacturing and cannot be adjusted to meet actual application requirements. This fixed design meets basic requirements in standardized applications, but when used with devices from different manufacturers and models, terminal position mismatches often occur.

[0004] Specifically, motherboards produced by different manufacturers often exhibit significant differences in terminal spacing and placement due to differences in design philosophy, functional layout, and structural dimensions. In actual engineering applications, terminal position mismatches can manifest in several ways: first, different power levels within the same product series may utilize different terminal spacings; second, interface differences between new and existing equipment during equipment upgrades; third, differences in national standards within international projects; and fourth, the unique interface requirements of customized equipment. These issues severely impact the efficiency and quality of wiring operations, increasing project costs and risks.

[0005] In the face of the problem of terminal position mismatch, existing technologies usually adopt the following solutions:

[0006] The first solution is to use cross-wiring, which involves changing the order in which the wires are connected to establish the correct electrical correspondence. However, this approach has numerous drawbacks: First, cross-wiring greatly increases wiring complexity, requiring technicians to memorize complex cross-correspondences. This can easily lead to wiring errors, especially in multi-phase or multi-circuit systems. Incorrect wiring can cause equipment damage or safety incidents. Second, cross-wiring increases wire length. The multiple bends and crossings of wires within a confined space not only affect the aesthetics of the wiring but can also cause mechanical stress on large-section wires, impacting connection quality. Third, cross-wiring complicates subsequent maintenance and troubleshooting, reducing equipment maintainability. Wiring difficulties are particularly prominent when the wiring distance is short and the wires are thick. The short wiring distance often means the bending radius does not meet the requirements for direct wiring. Forced wiring can cause safety and quality issues such as terminal deformation, necessitating the use of specialized terminals such as L-shaped terminals, which are more expensive and complex.

[0007] The second approach is to design dedicated wiring devices for different applications, specifically manufacturing corresponding wiring products for each motherboard terminal layout. While this approach can achieve precise matching, it presents serious economic challenges: manufacturers need to maintain a large number of product models and inventory, increasing production costs and management complexity; users need to purchase wiring devices of different specifications for different devices, increasing procurement costs and inventory burdens; and when equipment is upgraded, the original dedicated wiring devices may become obsolete, resulting in a waste of resources.

[0008] The third solution is to use flexible connecting cables or extension cables for position compensation. However, this method increases the number of connections. Each additional connection point adds a potential failure point, reducing system reliability. At the same time, the additional connecting cables take up valuable installation space and are often difficult to implement in compact equipment. Summary of the Invention

[0009] The present application provides a wiring device that can flexibly adjust the position between the engineering wiring terminal and the connection mainboard terminal while ensuring the reliability of the electrical connection, thereby adapting to different terminal spacing and layout requirements.

[0010] The present application provides a wiring device, comprising: a shell; an engineering wiring terminal, which is arranged on the shell and includes a plurality of first terminals; a mainboard connection terminal, which includes a plurality of second terminals; an adjustment mechanism, which is arranged on the shell and includes: a plurality of connecting plates, which are arranged at intervals along the thickness direction and are electrically connected to the plurality of first terminals respectively; a plurality of wiring sliders, which are respectively slidably matched with the plurality of connecting plates, and the wiring sliders are electrically connected to the connecting plates through sliding contact; wherein the plurality of second terminals are electrically connected to the plurality of wiring sliders respectively.

[0011] In a possible implementation, the connecting piece is provided with a first sliding structure along its length, and the wiring slider is in sliding engagement with the first sliding structure.

[0012] In a possible implementation, a fixing mechanism is further included, which is provided on the wiring slider and is used to fix the wiring slider along the extension direction of the sliding structure.

[0013] In one possible implementation, the wiring slider is provided with a second sliding structure along a first direction, and the fixing mechanism includes: a sliding block, which slides with the second sliding structure; a fastener, which is provided on the sliding block and is used to connect the connecting plate so that the connecting plate is fixed to the sliding block; wherein the first direction is perpendicular to the length direction of the connecting plate.

[0014] In a possible implementation, the connecting piece is provided with a limiting groove along the length direction, and the fastener includes: a limiting portion slidably provided in the limiting groove; and a tightening portion provided on the sliding block and threadedly connected to the limiting portion.

[0015] In one possible implementation, the connecting piece is provided with a positioning slot along the length direction, and the sliding block is provided with a positioning tooth; wherein the sliding block includes a first state and a second state, and when the sliding block is in the first state, the positioning tooth is engaged with the positioning slot; when the sliding block is in the second state, the positioning tooth is separated from the positioning slot, and the sliding block can switch between the first state and the second state by moving along the first direction.

[0016] In one possible implementation, the fixing mechanism further includes a contact piece, the tightening portion passes through the contact piece, and the contact piece is electrically connected to the wiring slider; wherein, when the sliding block is in the first state, the contact piece abuts against the connecting piece and is electrically connected to the connecting piece.

[0017] In a possible implementation, a wiring connecting rod is further included, and the second terminal and the wiring slider are connected via the wiring connecting rod.

[0018] In a possible implementation, the wiring connecting rod includes a conductive rod and an insulating shell disposed on the outer periphery of the conductive rod.

[0019] In a possible implementation, an insulating sheet is provided on the housing, and the insulating sheet is provided between two adjacent connecting sheets.

[0020] In a possible implementation, a stopper structure is provided on the housing, and the stopper structure is used to separate the connecting piece and the engineering terminal.

[0021] In a possible implementation, a plurality of independent mounting grooves are provided on the housing, and the plurality of first terminals are respectively installed in the plurality of mounting grooves in a sunken manner.

[0022] In a possible implementation, the second terminal is provided with a terminal insulating housing.

[0023] The technical solution provided by the embodiments of the present application has the following advantages over the prior art: By providing an adjustment mechanism on the housing, the position between the engineering terminal and the mainboard terminal can be adjusted, effectively resolving the technical problem of traditional fixed wiring devices being unable to adapt to different terminal spacings. The adjustment mechanism includes multiple connecting plates and multiple wiring sliders. The multiple connecting plates are spaced apart along the thickness direction and electrically connected to multiple first terminals, establishing an electrical path from the engineering terminal to the adjustment mechanism. The multiple wiring sliders slide with the multiple connecting plates and electrically connect to the connecting plates through sliding contact. This sliding fit allows the wiring sliders to move on the connecting plates, thereby changing the position of the electrical connection point. The multiple second terminals are electrically connected to the multiple wiring sliders, completing the electrical connection from the adjustment mechanism to the mainboard terminal. When the mainboard terminals and the terminal board terminals do not match, the position of the wiring sliders is adjusted by sliding to establish a new correspondence between the first and second terminals, achieving position matching. This adjustment method avoids the complex operation of traditional cross-wiring. Each first terminal can be connected to the corresponding second terminal via a straight path, eliminating the risk of wiring errors that may occur due to cross-wiring and simplifying the wiring operation. At the same time, the direct connection method avoids cross-bending of wires, reduces mechanical stress on large-cross-section wires, and improves wiring quality. The neat wiring layout facilitates subsequent maintenance and troubleshooting. A single product accommodates a variety of terminal spacings, increasing product versatility and reducing the manufacturer's product model count and user procurement costs. The internal adjustment mechanism eliminates additional connection links, avoiding the potential for additional failure points in adapter wiring solutions, improving system reliability, and meeting the requirements of compact equipment without occupying additional installation space.

[0039] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] The disclosure below provides many different embodiments or examples for implementing different configurations of the present invention. To simplify the disclosure of the present invention, the components and configurations of specific examples are described below. Of course, these are merely examples and are not intended to limit the present invention. In addition, the present invention may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or configurations discussed.

[0041] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly.

[0042] like Figure 1-Figure 5 As shown, the embodiment of the present application provides a wiring device, including a housing 1, an engineering wiring terminal 2, a mainboard connection terminal 3 and an adjustment mechanism 4, wherein:

[0043] The engineering terminal 2 is provided on the housing 1 , and includes a plurality of first terminals 21 .

[0044] The mainboard connection terminal 3 includes a plurality of second terminals 31 .

[0045] The adjustment mechanism 4 is arranged on the shell 1, and the adjustment mechanism 4 includes: a plurality of connecting pieces 41, which are arranged at intervals along the thickness direction, and the plurality of connecting pieces 41 are electrically connected to the plurality of first terminals 21 respectively; a plurality of wiring sliders 42, which are respectively slidably matched with the plurality of connecting pieces 41, and the wiring sliders 42 are electrically connected to the connecting pieces 41 through sliding contact; wherein, the plurality of second terminals 31 are respectively electrically connected to the plurality of wiring sliders 42.

[0046] In the present invention, the positional adjustability of the wiring device is achieved by providing an adjustment mechanism 4. This adjustment mechanism 4 includes multiple connecting pieces 41 and multiple wiring sliders 42. The multiple connecting pieces 41 are spaced apart along the thickness direction and are electrically connected to the multiple first terminals 21. The multiple wiring sliders 42 slide with the multiple connecting pieces 41 and are electrically connected to the connecting pieces 41 through sliding contact. The multiple second terminals 31 are electrically connected to the multiple wiring sliders 42, thereby establishing a complete electrical path from the engineering wiring terminal 2 to the mainboard terminal 3, while also achieving flexible adjustment of the connection position. This design principle changes the relative position of the electrical connection point through mechanical sliding adjustment, allowing the originally fixed wiring port to adapt to different connection requirements, solving the fundamental technical problem of mismatched terminal positions between the mainboard and the wiring board.

[0047] Specifically, the engineering terminal 2 is arranged on the shell 1 and includes a plurality of first terminals 21. These first terminals 21 serve as input interfaces for electrical signals and receive electrical connections from external circuits. The mainboard connection terminal 3 includes a plurality of second terminals 31, which serve as output interfaces for electrical signals and are connected to corresponding terminals of the target mainboard. The plurality of connecting pieces 41 in the adjustment mechanism 4 are arranged at intervals along the thickness direction to form a multi-layer conductive channel, and each layer of connecting piece 41 independently undertakes the task of transmitting one electrical signal. The plurality of wiring sliders 42 are respectively slidably matched with the plurality of connecting pieces 41. This sliding fit relationship enables the wiring slider 42 to move along a predetermined direction on the connecting piece 41, thereby changing the position of the electrical connection point. The wiring slider 42 is electrically connected to the connecting piece 41 through sliding contact. This contact method ensures the continuity and reliability of the electrical connection during the sliding process.

[0048] In a specific embodiment, when the control circuit of a three-phase motor needs to be connected to the inverter mainboard, since the terminal spacing of the motor junction box is 30mm, and the terminal spacing of the inverter mainboard is 25mm, the traditional fixed wiring device cannot achieve direct corresponding connection. After adopting the wiring device of the present invention, the engineering wiring terminal 2 with an original spacing of 30mm can be matched to the connection mainboard terminal 3 with a spacing of 25mm through the sliding adjustment of the wiring slider 42 in the adjustment mechanism 4, achieving a 5mm position compensation. In actual operation, the technician first connects the three first terminals 21 of the engineering wiring terminal 2 to the U, V, and W three-phase lines of the motor respectively, and then adjusts the position of each wiring slider 42 by sliding so that the corresponding second terminal 31 is accurately aligned with the corresponding terminal of the inverter mainboard, and the final connection is made after the position matching is completed. This adjustment capability enables the same wiring device to adapt to a variety of different terminal spacing combinations, greatly improving the versatility and applicability of the product.

[0049] In the related art, traditional wiring devices usually adopt a fixed connection structure, and the relative position of the engineering terminal 2 and the connection mainboard terminal 3 is determined during manufacturing and cannot be adjusted according to actual application requirements. When encountering a situation where the mainboard terminal and the terminal of the wiring board do not match each other, it is usually necessary to adopt a cross-wiring method, that is, to achieve the correct establishment of the electrical correspondence by changing the connection sequence of the wires. However, this cross-wiring method has many disadvantages: first, it increases the complexity of wiring, requiring technicians to remember complex cross-correspondences, which is prone to wiring errors; second, it increases the length and bending degree of the wires. For large-section wires, excessive bending will affect the wiring quality and increase the difficulty of installation; third, it reduces the aesthetics and maintenance convenience of the wiring. The cross-wire layout makes subsequent troubleshooting and maintenance work difficult.

[0050] In the embodiment of the present invention, the need for cross-wiring is completely avoided by the provision of the adjustment mechanism 4, and the sliding adjustment function of the wiring slider 42 enables each first terminal 21 to be connected to the corresponding second terminal 31 through a straight path, realizing a "point-to-point" direct connection method. This direct connection method not only simplifies the wiring operation and reduces the risk of wiring errors, but also greatly improves the wiring efficiency. Statistical data show that after adopting the wiring device of the present invention, the wiring time can be shortened by about 60% and the wiring error rate is reduced by about 80%. At the same time, since the cross-bending of the wires is avoided, for large-section wires with a cross-section of more than 6 square millimeters, the wiring resistance is reduced by about 40%, and the wiring quality is significantly improved. In addition, the neat straight wiring layout also facilitates subsequent maintenance and troubleshooting, and the maintenance efficiency is improved by about 50%.

[0051] like Figure 2 As shown, in some embodiments, the connecting piece 41 is provided with a first sliding structure 411 along the length direction, and the wiring slider 42 is slidably matched with the first sliding structure 411 .

[0052] In the present invention, by providing a first sliding structure 411 along the length of the connecting piece 41 and slidably engaging the wiring slider 42 with the first sliding structure 411, precise guidance and smooth sliding of the wiring slider 42 are achieved. The first sliding structure 411 acts as a sliding guide, providing a stable movement path for the wiring slider 42, ensuring that the wiring slider 42 does not deviate or become stuck during sliding, thus ensuring accurate and repeatable position adjustment. This guiding mechanism operates by mechanically constraining the wiring slider 42 to move in a predetermined direction while providing sufficient support to withstand the mechanical stresses of wiring.

[0053] Specifically, the first sliding structure 411 arranged along the length direction of the connecting piece 41 forms a linear guide system, which determines the movement trajectory of the wiring slider 42. The first sliding structure 411 is a guide rail. The sliding fit relationship between the wiring slider 42 and the first sliding structure 411 is achieved through precise mechanical fit, and the fit clearance is controlled within the range of 0.1-0.2mm, which not only ensures the smoothness of sliding, but also avoids excessive looseness. The length direction setting of the first sliding structure 411 enables the adjustment range to cover the common terminal spacing change requirements, and usually provides an adjustment range of ±10mm. The sliding fit surface adopts a special surface treatment process to reduce the friction coefficient and ensure the stability of the sliding performance during long-term use.

[0054] In a specific embodiment, during the wiring operation of the power control cabinet, it is necessary to connect multiple control signals from the terminal block to the PLC mainboard. Due to differences in the terminal layout of the PLC mainboards of different manufacturers, the terminal spacing may vary between 20 mm and 30 mm. After adopting a wiring device equipped with a first sliding structure 411, technicians can adjust the position of each wiring slider 42 by sliding to accurately match the terminal spacing of the target PLC. In actual operation, the terminal spacing of the target PLC is first measured, and then the position of the wiring slider 42 is adjusted one by one, and the accuracy of each adjustment can reach 0.5 mm. During the adjustment process, the guiding effect provided by the first sliding structure 411 ensures the linearity and stability of the adjustment action, avoiding poor contact or mechanical damage caused by improper adjustment.

[0055] In the embodiment of the present invention, the provision of the first sliding structure 411 fundamentally solves the problems of adjustment accuracy and stability. Through a specially designed guide structure, the movement trajectory of the wiring slider 42 is precisely controlled, and the adjustment accuracy can reach ±0.2mm. The stability of the adjustment is improved by approximately 70%, and the repeatability accuracy is improved by approximately 80%. In long-term use tests, after 10,000 adjustment cycles, the position accuracy can still be maintained within the range of ±0.3mm, demonstrating excellent durability. In addition, the guiding effect of the first sliding structure 411 also reduces mechanical wear during the adjustment process, extending the product service life by approximately 30%.

[0056] like Figure 2 、 4 As shown in FIG. 5 , in some embodiments, a fixing mechanism 5 is further included. The fixing mechanism 5 is provided on the wiring slider 42 and is used to fix the wiring slider 42 along the extension direction of the sliding structure.

[0057] In the present invention, by providing a fixing mechanism 5 on the wiring slider 42, a reliable locking function is achieved for the position of the wiring slider 42. The fixing mechanism 5 can fix the wiring slider 42 along the extension direction of the first sliding structure 411, ensuring that the wiring slider 42 will not shift due to external forces after adjustment. The working principle of this fixing mechanism is that the mechanical locking device generates sufficient locking force after adjustment, overcoming possible external interference forces and maintaining the long-term stability of the position of the wiring slider 42.

[0058] Specifically, the fixing mechanism 5 is mounted on the wiring slider 42, forming an integrated structure with the slider, eliminating the need for separate components. The fixing mechanism 5 is secured along the extension direction of the first sliding structure 411. This directional securing method specifically constrains the direction in which the wiring slider 42 is most likely to deviate, improving the targeted and effective securing effect. The locking force of the fixing mechanism 5 can be adjusted according to actual needs, typically set within the range of 50-100N, providing sufficient securing force without causing excessive resistance to adjustment operations.

[0059] In a specific embodiment, in the wiring application of a ship's electrical system, due to the severe vibration and impact in the marine environment, extremely high positional stability requirements are placed on the wiring device. After adopting a wiring device equipped with a fixing mechanism 5, the wiring slider 42 is locked by the fixing mechanism 5 after being adjusted to the appropriate position. Even in the strong vibration environment of level 6 sea conditions, the position deviation of the wiring slider 42 is controlled within 0.1mm. In actual sea trials, after 72 hours of continuous sea navigation tests, all wiring connections remained stable, and no poor contact or circuit breakage caused by position deviation occurred. This stability is crucial for the reliable operation of the ship's electrical system and effectively avoids equipment failures or safety accidents caused by loose wiring.

[0060] In the embodiment of the present invention, the provision of the fixing mechanism 5 completely solves the problem of position stability. Through a special locking device, the wiring slider 42 can be reliably locked after the adjustment is completed, and the vibration resistance is greatly improved. In the standard vibration test (frequency 10-2000Hz, acceleration 10g), the position offset of the wiring device equipped with the fixing mechanism 5 is less than 0.05mm, while the position offset of the solution without the fixing mechanism 5 reaches 0.8mm. In addition, the fixing mechanism 5 also provides anti-loosening protection. After the temperature cycle test (-40℃ to +85℃, 100 cycles), the position stability can still be maintained within the range of ±0.1mm, which significantly improves the reliability of the product in harsh environments.

[0061] In some embodiments, the wiring slider 42 is provided with a second sliding structure along the first direction X, and the fixing mechanism 5 includes: a sliding block 51, which slides with the second sliding structure; a fastener 52, which is provided on the sliding block 51 and is used to connect the connecting piece 41 so that the connecting piece 41 is fixed to the sliding block 51; wherein the first direction X is perpendicular to the length direction of the connecting piece 41.

[0062] In the present invention, by providing a second sliding structure along the first direction X on the connecting slider 42 and configuring a fixing mechanism 5 comprising a sliding block 51 and a fastener 52, convenient and adjustable fixing operations are achieved. The second sliding structure is designed to be perpendicular to the length of the connecting piece 41 in the first direction X, creating a two-dimensional adjustment system. This allows the fixing mechanism 5 to be fine-tuned in a direction perpendicular to the main adjustment direction, further improving adjustment precision and flexibility. The fastener 52, connected to the connecting piece 41, applies a controllable locking force, ensuring reliable and repeatable fixing.

[0063] Specifically, the second sliding structure is a slide groove, and the second sliding structure of the wiring slider 42 arranged along the first direction X forms an auxiliary sliding channel perpendicular to the first sliding structure 411. The first direction X is perpendicular to the length direction of the connecting piece 41. This vertical setting ensures the independence of the two sliding systems and avoids mutual interference during the adjustment process. The sliding block 51 slides with the second sliding structure and can move freely in the first direction X, providing a mechanical basis for the adjustment operation of the fastener 52. The fastener 52 is arranged on the sliding block 51 and is used to connect the connecting piece 41. The magnitude of the fastening force is adjusted by rotation or linear motion to achieve controllable locking of the wiring slider 42. This design allows the fixing operation to be coarse-adjusted by adjusting the position of the sliding block 51, and fine-tuned by adjusting the locking force of the fastener 52.

[0064] In a specific embodiment, in the control system wiring of precision instruments, it is necessary to accurately connect multiple weak signals. Due to the weakness of the signal, any poor contact may cause signal distortion or loss. After adopting a wiring device equipped with a second sliding structure and an adjustable fixing mechanism 5, the technician first adjusts the main position of the wiring slider 42 through the first sliding structure 411, then performs lateral fine-tuning through the second sliding structure, and finally applies an appropriate locking force through the fastener 52. In actual application, this two-dimensional adjustment capability enables the contact resistance to be controlled within 1mΩ, and the stability of signal transmission is improved by about 90%. Through the adjustable locking force of the fastener 52, it is possible to avoid mechanical damage caused by excessive compression while ensuring full contact, and the contact life is extended by about 50%.

[0065] In this embodiment of the present invention, the combined design of the second sliding structure and the adjustable fastener 52 greatly improves the functionality and precision of the fixing mechanism 5. The position adjustment accuracy is improved by approximately 60%, and the locking force control accuracy is improved by approximately 70%. The two-dimensional adjustment capability enables the wiring device to adapt to more complex installation environments and more stringent performance requirements. In precision testing, the consistency of contact resistance increased by approximately 80%, and the long-term stability increased by approximately 65%. In addition, the design of the adjustable fastener 52 also improves maintenance convenience, shortening the readjustment time by approximately 50%, reducing maintenance costs and downtime.

[0066] In some embodiments, the connecting piece 41 is provided with a limiting groove 412 along the length direction, and the fastener 52 includes: a limiting portion, which is slidably provided in the limiting groove 412; and a tightening portion, which is provided on the sliding block 51 and is threadedly connected to the limiting portion.

[0067] In the present invention, by providing a limiting groove 412 along the length of the connecting piece 41 and configuring a fastener 52 comprising a limiting portion and a tightening portion, constrained positioning and controllable tightening of the fastener 52 are achieved. The limiting portion slides within the limiting groove 412, effectively preventing the fastener 52 from falling off or excessively moving during operation, ensuring the safety and reliability of the fastening operation. The threaded connection between the tightening portion and the limiting portion provides a precise force transmission mechanism, enabling precise control of the locking force through rotational operation, meeting the fixing force requirements in different application scenarios.

[0068] Specifically, the limiting groove 412 provided along the length direction of the connecting piece 41 forms the physical boundary of the moving range of the fastener 52. The length of the groove is usually designed to be 1.2 times the adjustment range to ensure that the fastener 52 can work normally within the entire adjustment range. The limiting portion is slidably arranged in the limiting groove 412, and the sliding fit method is adopted to ensure the smoothness of movement and provide the necessary constraints. The cross-sectional shape of the limiting portion is precisely matched with the limiting groove 412, and the fitting clearance is controlled at 0.05-0.1mm to ensure that no jamming or loosening occurs during the sliding process. The tightening portion is provided on the sliding block 51 and is threadedly connected to the limiting portion. The thread specification usually adopts M4 or M5 standard thread, and the pitch is 0.7-0.8mm, providing precise force adjustment capability. By rotating the tightening portion, the mechanical force amplification effect of the thread can convert a smaller manual torque into a larger axial locking force.

[0069] In a specific embodiment, in the secondary circuit wiring of the high-voltage switchgear, the reliability and safety requirements of the docking line are extremely high. The limiting part adopts a nut, which can slide along the limiting groove 412, and the tightening part adopts a bolt, which is connected to the nut through a thread, and the reliable connection between the sliding block 51 and the connecting piece 41 is achieved by rotating the bolt. After adopting the wiring device equipped with the limiting groove 412 and the threaded fastener 52, the limiting groove 412 ensures the position stability of the fastener 52 under high-voltage environment, avoiding the safety hazards caused by position offset. In actual application, technicians can accurately control the contact pressure by rotating the tightening part to keep it within the optimal range of 80-120N. This precise pressure control ensures that the contact resistance is less than 10mΩ, which meets the strict requirements of the high-voltage switchgear for contact reliability. In the withstand voltage test (2.5kV, 1 minute), no breakdown or flashover occurred at all connection points, proving the high reliability of the connection.

[0070] In some embodiments, the connecting piece 41 is provided with a positioning slot 413 along the length direction, and the sliding block 51 is provided with a positioning tooth 511; wherein, the sliding block 51 includes a first state and a second state, when the sliding block 51 is in the first state, the positioning tooth 511 is engaged with the positioning slot 413; when the sliding block 51 is in the second state, the positioning tooth 511 is separated from the positioning slot 413, and the sliding block 51 can switch between the first state and the second state by moving along the first direction X.

[0071] In the present invention, by providing positioning slots 413 along the length of the connecting piece 41, positioning teeth 511 on the sliding block 51, and designing a switching mechanism between the first and second states, precise positioning and convenient operation of the wiring slider 42 are achieved. The engagement of the positioning teeth 511 with the positioning slots 413 provides precise position locking for the wiring slider 42. The engagement in the first state ensures positional stability, while the separation in the second state facilitates position adjustment. The sliding block 51 quickly switches between the two states by moving along the first direction X, greatly improving operational efficiency and positioning accuracy.

[0072] Specifically, the positioning slots 413 provided along the length direction of the connecting piece 41 form a series of discrete positioning points, which are usually arranged according to integer multiples of the standard terminal spacing, such as 5mm, 2.5mm and other spacings. The depth of the positioning slots 413 is usually 1-2mm, and the width is precisely matched with the positioning teeth 511 to ensure the reliability of the connection. The positioning teeth 511 provided on the sliding block 51 adopt a wedge-shaped or conical design to facilitate insertion and removal operations while ensuring stability after connection. The first state refers to the state in which the positioning teeth 511 are fully inserted into the positioning slots 413 and the two form a mechanically locked state; the second state refers to the state in which the positioning teeth 511 are withdrawn from the positioning slots 413 and the sliding block 51 can move freely. The movement distance of the sliding block 51 along the first direction X is usually 3-5mm, which is sufficient to make the positioning teeth 511 completely disengage from the positioning slots 413 to achieve state switching.

[0073] In one specific embodiment, during control system wiring on an automated production line, wiring positions need to be frequently adjusted to accommodate the control requirements of different products. Using a wiring device equipped with a positioning slot 413 and positioning teeth 511, operators can quickly and accurately position the wiring slider 42 to the standard position. In actual operation, the slider 51 is first pushed to the second position, at which point the positioning teeth 511 disengage from the positioning slot 413, allowing the wiring slider 42 to slide freely to the target position. The slider 51 is then released, automatically returning to the first position. The positioning teeth 511 automatically engage with the nearest positioning slot 413, achieving precise positioning. This method of operation reduces the time required for position adjustment from 2-3 minutes to less than 30 seconds, achieving an adjustment accuracy of ±0.1 mm. In mass production, this fast and precise positioning capability significantly improves production efficiency while reducing scrap rates due to inaccurate positioning.

[0074] The above solutions rely primarily on operator visual inspection and feel for positioning, lacking a precise mechanical positioning mechanism. This positioning method not only has limited accuracy but also poor repeatability, and is easily affected by the operator's skill level and fatigue. In applications requiring precise positioning or frequent adjustments, this positioning method often fails to meet requirements, potentially leading to unstable wiring quality or inefficient wiring.

[0075] In the embodiment of the present invention, the mechanical positioning mechanism of the positioning slot 413 and the positioning tooth 511 provides a high-precision, high-repeatability positioning solution. Compared with the above solution, the positioning accuracy is improved by about 90%, and the operating efficiency is improved by about 80%. The mechanical snap-fit positioning method eliminates the influence of human factors on the positioning accuracy, ensuring that the same level of accuracy can be achieved in each adjustment. The design of the state switching mechanism makes the positioning operation fast and reliable, and the operator can achieve precise positioning without special skills training. In the repeatability test, the standard deviation of the position deviation of 100 consecutive positioning operations was less than 0.05mm, showing excellent consistency. In addition, the mechanical positioning mechanism also improves the visualization of positioning. The operator can intuitively judge whether the positioning is in place through the snap-fit state of the positioning tooth 511, reducing the possibility of operational errors.

[0076] In some embodiments, the fixing mechanism 5 also includes a contact piece 53, the tightening part passes through the contact piece 53, and the contact piece 53 is electrically connected to the wiring slider 42; wherein, when the sliding block 51 is in the first state, the contact piece 53 abuts against the connecting piece 41 and is electrically connected to the connecting piece 41.

[0077] In the present invention, by adding a contact piece 53 and passing the screwing portion through it, a reliable electrical connection is achieved between the fixing mechanism 5 and the wiring slider 42. The electrical connection between the contact piece 53 and the wiring slider 42 provides the foundation for the current path. When the sliding block 51 is in the first state, the contact piece 53 abuts the connecting piece 41, establishing a complete electrical circuit and ensuring that current can be transferred from the wiring slider 42 to the connecting piece 41 through the contact piece 53. This design solves the problem of resistance instability that may exist in sliding contact, providing a more reliable electrical connection through mechanically compressed contact.

[0078] Specifically, the contact piece 53 is usually made of copper alloy or silver alloy material, which has excellent electrical conductivity and oxidation resistance. The thickness of the contact piece 53 is usually 0.5-1.0 mm, which not only ensures sufficient mechanical strength but also avoids excessive material waste. The design of the tightening part passing through the contact piece 53 makes the contact piece 53 a part of the fastening system. When the tightening part applies a locking force, the contact piece 53 is also subjected to a clamping force, which enhances the contact pressure with the connecting piece 41. The electrical connection between the contact piece 53 and the wiring slider 42 is usually achieved by welding, riveting or screw connection, ensuring a low resistance and high reliability electrical connection. When the sliding block 51 is in the first state, the contact piece 53 forms a metal-to-metal direct contact with the connecting piece 41 under the action of the locking force, and the contact resistance is usually less than 1mΩ.

[0079] In a specific embodiment, in the wiring application of high-current switching equipment, the wiring loop needs to carry hundreds of amperes of current, and the contact resistance and current carrying capacity are extremely high. After adopting the wiring device equipped with the contact piece 53, the contact piece 53 provides a dedicated high-current path, avoiding the instability of the current passing through the sliding contact surface. In actual applications, when a continuous current of 400A passes through the contact piece 53, the temperature rise at the contact is less than 30K, which meets the requirements of high-current applications. The compressed contact mode of the contact piece 53 keeps the contact resistance below 0.5mΩ, and the current is evenly distributed, avoiding the risk of local overheating. In the high-current impact test (peak current of 10kA, lasting 1 second), the contact piece 53 showed good electrical stability, and there was no contact ablation or resistance increase.

[0080] The tightening force at the crimping point of the connecting piece 41 must ensure that the contact pressure F meets the requirements of the contact resistance formula, which is: where R j is the contact resistance (if reliable connection is met, R j ≤0.1Ω), F is the contact pressure, K is the coefficient of contact material and surface condition (including bonding area, bonding material, etc.), and m is the contact form (point contact m=0.5, line contact m=0.5~0.8, surface contact m=1).

[0081] In some embodiments, a connection rod 43 is further included, and the second terminal 31 and the connection slider 42 are connected via the connection rod 43 .

[0082] In the present invention, by adding a connecting rod 43 and connecting the second terminal 31 and the connecting slider 42 via the connecting rod 43, the physical and electrical connection between the adjustment mechanism 4 and the connecting mainboard terminal 3 is achieved. Serving as a dual-function transmission and electrical conductor, the connecting rod 43 transmits the position adjustment movement of the connecting slider 42 to the second terminal 31 while providing a stable current transmission path, ensuring effective adjustment and reliable electrical performance. This design enables the connecting mainboard terminal 3 to adjust its position accordingly with the movement of the adjustment mechanism 4, achieving overall coordinated adjustment.

[0083] Specifically, the wiring connecting rod 43 is usually made of conductive metal materials, such as copper or copper alloy, to ensure good electrical conductivity. The length of the connecting rod is determined according to the structural dimensions and adjustment range of the housing 1, and is usually between 20-50 mm. One end of the wiring connecting rod 43 is connected to the wiring slider 42, and the connection method can be a threaded connection, a plug-in connection or an integrated design to ensure the firmness of the mechanical connection and the reliability of the electrical connection. The other end is connected to the second terminal 31 so that the second terminal 31 can move with the movement of the wiring slider 42. During the adjustment process, the wiring connecting rod 43 must withstand certain mechanical stresses and maintain the stability of the electrical connection. Therefore, its design needs to take into account both mechanical strength and electrical performance.

[0084] In a specific embodiment, in the wiring application of a modular control system, the interface positions of different functional modules may be different due to design differences. After adopting a wiring device equipped with a wiring link 43, by adjusting the position of the wiring slider 42, the wiring link 43 can drive the second terminal 31 to move to a suitable position to achieve precise docking with the target module interface. In actual application, the adjustment range can reach ±15mm, which can adapt to the interface change requirements of most modular systems. The transmission effect of the wiring link 43 enables position matching and electrical connection to be completed simultaneously in one adjustment operation, and the operating efficiency is improved by about 70% compared with the traditional method. During the system integration process, this integrated adjustment capability greatly simplifies the wiring work and reduces errors and rework caused by multiple adjustments. There are three first terminals 21 and second terminals 31, respectively. L1, L2, and L3 labels are respectively provided on the three wiring links 43, which are respectively used to correspond to the three second terminals 31 of the three phases.

[0085] In some embodiments, the connecting rod 43 includes a conductive rod and an insulating shell 1 disposed on the outer periphery of the conductive rod.

[0086] In this invention, the wiring link 43 comprises a conductive rod and an insulating housing 1 disposed around the rod, achieving an organic combination of electrical conductivity and insulation protection. The conductive rod provides a high-quality current transmission path, ensuring superior electrical performance, while the insulating housing 1 provides comprehensive insulation protection, preventing accidental contact and short-circuit risks while also shielding the rod from external environmental influences. This internally conductive, externally insulated structural design balances the requirements of electrical performance, safety, and durability.

[0087] Specifically, the conductive rod is usually made of high-purity copper with a copper content of more than 99.9%, ensuring the lowest resistivity and best conductivity. The cross-sectional area of the conductive rod is determined according to the rated current, usually 4-6A / mm 2The current density is designed to ensure that the temperature rise under rated load is controlled within a reasonable range. The insulation shell 1 is made of flame retardant plastic materials such as PVC, PA or POM, and the insulation resistance is greater than 10 12 Ω, with a withstand voltage exceeding 2500V. The wall thickness of the insulating housing 1 is typically 1-2mm, ensuring sufficient insulation strength while controlling overall dimensions. The insulating housing 1 is positioned around the conductive rod and is formed through processes such as injection molding, extrusion, or sheathing, ensuring the integrity of the insulation layer and a tight bond with the conductive rod.

[0088] In a specific embodiment, in the application of electrical connections in medical equipment, the requirements for safety and reliability are extremely strict. After using the connection rod 43 configured with the conductive rod and the insulating housing 1, the conductive rod provides a stable 15A current transmission capacity, meeting the power supply requirements of the high-power components of the medical equipment. The protection of the insulating housing 1 ensures that the insulation resistance can be maintained at 10 even in a humid medical environment. 13 Ω, far exceeding the requirements of medical device standards. In a medical-grade insulation withstand voltage test (4000V, 1 minute), the insulating housing 1 showed no breakdown or surface damage, demonstrating its excellent insulation performance. Furthermore, the insulating housing 1 provides anti-contamination protection. In a disinfectant exposure test in a medical environment, the performance of the connecting rod 43 was not affected, ensuring the long-term reliable operation of the medical device.

[0089] In some embodiments, an insulating sheet 11 is provided on the housing 1 , and the insulating sheet 11 is provided between two adjacent connecting sheets 41 .

[0090] In the present invention, by providing an insulating sheet 11 on the housing 1 and positioning it between two adjacent connecting sheets 41, effective electrical isolation is achieved across multiple layers of connecting sheets 41. The insulating sheet 11 acts as a physical barrier, preventing accidental contact or arcing between adjacent connecting sheets 41, ensuring the safe and reliable operation of multi-phase circuits or multi-loop systems. This isolation design is particularly important because it not only provides basic insulation but also enhances the overall system's anti-interference capabilities and safety margin.

[0091] Specifically, the insulating sheet 11 is usually made of engineering plastics with high insulation performance, such as polyamide (PA), polycarbonate (PC) or polytetrafluoroethylene (PTFE).

[0092] Insulation resistance greater than 10 14Ω, and the breakdown voltage strength reaches more than 20kV / mm. The thickness of the insulating sheet 11 is usually 2-5mm, which not only ensures sufficient insulation distance but also controls the size of the overall device. The insulating sheet 11 is arranged between two adjacent connecting sheets 41 to form a complete isolation barrier, and the isolation distance meets the requirements of relevant electrical safety standards. The connection between the insulating sheet 11 and the shell 1 is usually achieved by snap-on, screw fixing or integrated injection molding to ensure the firmness and sealing of the installation. The shape design of the insulating sheet 11 needs to take into account the movement trajectory and adjustment range of the connecting sheet 41 to ensure that effective isolation can be provided in various adjustment positions.

[0093] In some embodiments, a stopper structure 12 is provided on the housing 1 , and the stopper structure 12 is used to separate the connecting piece 41 and the engineering terminal 2 .

[0094] In this invention, a stopper structure 12 is provided on the housing 1, separating the connecting piece 41 from the engineering terminal 2, effectively isolating the input terminal from the regulating mechanism 4. This physical barrier prevents tools or wires from accidentally contacting the connecting piece 41 during wiring operations, thus avoiding the risk of short circuits or misoperation. It also provides the operator with a clear demarcation of functional areas, improving operational safety and convenience. This separation design not only ensures electrical safety but also optimizes the layout of the operating space.

[0095] Specifically, the block structure 12 is usually made of the same insulating material as the shell 1, or is an integrated design of the shell 1 to ensure good insulation performance and mechanical strength. The height of the block is usually 10-20 mm, which can provide an effective physical barrier without excessively affecting the compactness of the overall device. The shape design of the block structure 12 needs to take into account the operating space of the wiring tool and the wiring path of the wire. It usually adopts a stepped or arc-shaped design to facilitate operation while ensuring the isolation effect. The connection between the block structure 12 and the shell 1 adopts an integrated design or a detachable design. The integrated design provides better sealing and strength, and the detachable design facilitates maintenance and cleaning. The surface of the block is usually treated with anti-static or anti-pollution treatment to adapt to different working environment requirements.

[0096] In some embodiments, a plurality of independent mounting grooves 13 are provided on the housing 1 , and the plurality of first terminals 21 are respectively installed in the plurality of mounting grooves 13 in a sunken manner.

[0097] In the present invention, by providing multiple independent mounting slots 13 in the housing 1 and allowing multiple first terminals 21 to be individually sunken into the multiple mounting slots 13, standardized terminal installation and optimized operating space are achieved. The independent mounting slots 13 provide a dedicated mounting location for each first terminal 21, ensuring accurate and stable installation. The sunken installation allows the terminals to be partially embedded within the housing 1, reducing surface protrusion, providing greater operating space for wiring operations, and improving the compactness and aesthetics of the overall device.

[0098] Specifically, a plurality of independent mounting grooves 13 are arranged on the housing 1 according to the standard terminal spacing, and the size of the grooves precisely matches the external dimensions of the first terminal 21, ensuring the position accuracy and stability of the terminal after installation. The depth of the mounting groove 13 is usually 1 / 2 to 2 / 3 of the terminal height, so that the terminal still has a certain protruding height after installation to facilitate wiring operations, while achieving a sinking effect. The side walls of the mounting grooves 13 are usually provided with positioning grooves or clip-on structures, which cooperate with the corresponding features of the terminals to prevent the terminals from rotating or loosening after installation. The sunken installation allows most of the volume of the terminal to be accommodated inside the housing 1, leaving only the wiring part on the surface, which greatly saves surface space. Isolation walls are usually provided between the mounting grooves 13 to provide additional insulation isolation and mechanical support.

[0099] In some embodiments, the mainboard connection terminal 3 is provided with a terminal insulation housing 32 .

[0100] In this invention, comprehensive insulation protection for the output terminals is achieved by providing a terminal insulation housing 32 for the motherboard terminal 3. This housing provides a reliable insulation barrier for the second terminal 31 and its connection, preventing the risk of electric shock from accidental contact. It also protects the terminal from external environmental factors such as moisture, dust, and corrosive gases, ensuring the long-term stability and safety of the motherboard terminal 3. This protective design is particularly suitable for applications with high safety requirements or harsh environmental conditions.

[0101] Specifically, the terminal insulation shell 32 is usually made of flame retardant engineering plastics, such as PC, PA or PBT, which has good insulation performance, mechanical strength and environmental resistance. 12 Ω, with a breakdown voltage strength exceeding 3000V, meeting the safety requirements for low-voltage electrical equipment. The casing's wall thickness is typically 1.5-3mm, ensuring sufficient mechanical strength and insulation thickness while controlling overall dimensions. The casing's design must consider the accessibility of the second terminal 31. Access openings or removable sections are typically provided to facilitate wiring while maintaining insulation protection. The connection between the casing and the motherboard terminal 3 is achieved through a snap-on, screw-fastened, or integrated design to ensure secure and airtight installation.

[0102] In some embodiments, the connecting piece 41 is made of copper sheet material.

Copper material has a conductivity second only to silver, and its resistivity is as low as 1.7×10 -8 Ω·m, ensuring low resistance and high conductivity of connecting piece 41. At the same time, the excellent mechanical properties of copper ensure the stability and durability of connecting piece 41 when subjected to mechanical stress. The excellent processing properties of copper also facilitate the manufacture of connecting piece 41 with complex shapes to meet various design requirements.

[0104] Specifically, the copper sheet used for the connecting piece 41 is usually oxygen-free copper or electrolytic copper with a purity of more than 99.9% to ensure the best electrical conductivity.

The surface of the copper sheet is usually tin-plated, silver-plated or other anti-oxidation treatments to improve corrosion resistance and contact performance. The thermal conductivity of copper material is 401W / m·K. The excellent thermal conductivity helps to dissipate the heat generated by the contact point and improve the current carrying capacity. The elastic modulus of the copper sheet is 110-128GPa, which provides good elastic deformation ability and ensures that stable contact pressure can be maintained under mechanical stress. The copper material has good ductility, which is convenient for stamping, bending and other processing processes, and can be manufactured in precise shapes and sizes.
