Description

Technical Field

[0001] This application relates to the field of electrical connection equipment technology, and more particularly to a wiring device. Background Technology

[0002] In modern electrical systems and electronic equipment, wiring devices, as crucial components for electrical connections, are widely used in various electrical devices such as control cabinets, distribution boxes, industrial automation equipment, frequency converters, and PLC systems. The main function of wiring devices is to achieve the electrical connection between external wiring and the internal mainboard of the equipment, ensuring reliable transmission of electrical signals.

[0003] Traditional wiring devices typically employ a fixed connection structure, where the relative positions of the engineering terminals and the mainboard connection are determined during product manufacturing and cannot be adjusted according to actual application requirements. While this fixed design can meet basic requirements in standardized applications, it often leads to terminal mismatch issues when dealing with equipment from different manufacturers and of different models.

[0004] Specifically, due to differences in design philosophy, functional layout, and structural dimensions, motherboards produced by different manufacturers often exhibit significant variations in the spacing and placement of their terminals. In practical engineering applications, terminal mismatch issues manifest in several ways: first, different power ratings within the same product series may use different terminal spacings; second, differences in interfaces between old and new equipment during upgrades; third, differences in standards across different countries within international projects; and fourth, specific interface requirements in customized equipment. These problems severely impact the efficiency and quality of wiring work, increasing project costs and risks.

[0005] To address the issue of mismatched terminal positions, existing technologies typically employ the following solutions:

[0006] The first approach is to use cross-wiring, which establishes the correct electrical correspondence by changing the order of the wire connections. However, this method has several drawbacks: First, cross-wiring significantly increases the complexity of the wiring, requiring technicians to memorize intricate cross-correspondences and increasing the risk of wiring errors, especially in multi-phase or multi-circuit systems where incorrect wiring can lead to equipment damage or safety accidents. Second, cross-wiring requires increased wire length; multiple bends and crossings within a limited space not only affect the aesthetics of the wiring but can also cause mechanical stress on large-section wires, affecting connection quality. Third, cross-wiring makes subsequent maintenance and troubleshooting difficult, reducing equipment maintainability. The wiring difficulty is particularly pronounced when the wiring distance is short and the wire is thick. Short distances often mean that the bending radius does not meet the requirements for direct wiring, and forced wiring can cause safety and quality issues such as terminal deformation. Special terminals such as L-shaped terminals are required for transition, increasing costs and complicating the wiring process.

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

[0008] The third option is to use flexible connecting lines or extension lines for position compensation. However, this method increases the number of connection points, and each additional connection point adds a potential point of failure, reducing the reliability of the system. At the same time, the extra connecting lines occupy valuable installation space, which is often difficult to implement in compact equipment. Utility Model Content

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

[0010] This application provides a wiring device, comprising: a housing; an engineering terminal disposed on the housing, the engineering terminal including a plurality of first terminals; a main board terminal including a plurality of second terminals; and an adjustment mechanism disposed on the housing, the adjustment mechanism including: a plurality of connecting pieces, the plurality of connecting pieces being spaced apart along the thickness direction, the plurality of connecting pieces being electrically connected to the plurality of first terminals respectively; and a plurality of wiring sliders, each slidingly engaging with the plurality of connecting pieces, the wiring sliders being electrically connected to the connecting pieces through sliding contact; wherein, the plurality of second terminals are respectively electrically connected to the plurality of wiring sliders.

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

[0012] In one possible implementation, a fixing mechanism is also included, which is disposed 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 connector slider is provided with a second sliding structure along a first direction, and the fixing mechanism includes: a sliding block that slides in cooperation with the second sliding structure; and a fastener disposed on the sliding block for connecting the connecting piece to fix the connecting piece to the sliding block; wherein the first direction is perpendicular to the length direction of the connecting piece.

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

[0015] In one possible implementation, the connecting piece is provided with a positioning slot along its length, and the sliding block is provided with positioning teeth; wherein, the sliding block includes a first state and a second state, when the sliding block is in the first state, the positioning teeth engage with the positioning slot; when the sliding block is in the second state, the positioning teeth separate 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, through which the tightening part passes, and the contact piece is electrically connected to the wiring slider; wherein, when the slider is in the first state, the contact piece abuts against the connecting piece and is electrically connected to the connecting piece.

[0017] In one possible implementation, a wiring link is also included, and the second terminal and the wiring slider are connected via the wiring link.

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

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

[0020] In one possible implementation, the housing is provided with a stop structure, which is used to separate the connecting piece and the engineering terminal.

[0021] In one possible implementation, the housing is provided with multiple independent mounting slots, and multiple first terminals are respectively installed in the multiple mounting slots in a recessed manner.

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

[0023] Compared with the prior art, the technical solution provided in this application has the following advantages: By setting an adjustment mechanism on the housing, the position between the engineering terminal and the main board terminal is adjustable, effectively solving the technical problem that traditional fixed wiring devices cannot adapt to different terminal spacings. The adjustment mechanism includes multiple connecting pieces and multiple wiring sliders. The multiple connecting pieces are spaced apart along the thickness direction and are electrically connected to multiple first terminals, establishing an electrical path from the engineering terminal to the adjustment mechanism. The multiple wiring sliders are slidably engaged with the multiple connecting pieces, electrically connected to the connecting pieces through sliding contact. This sliding engagement allows the wiring sliders to move on the connecting pieces, thereby changing the position of the electrical connection point. Multiple second terminals are electrically connected to the multiple wiring sliders, completing the electrical connection from the adjustment mechanism to the main board terminal. When the main board terminal and the terminal block terminal are mismatched, the position of the sliding adjustment sliders is adjusted 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 through a straight path, eliminating the risk of wiring errors that may result from cross-wiring and simplifying the wiring operation. Meanwhile, the direct connection method avoids wire crossings and bends, reduces mechanical stress on large-section wires, improves wiring quality, and the neat wiring layout facilitates subsequent maintenance and troubleshooting. A single product can adapt to various terminal spacings, increasing product versatility and reducing the number of product models for manufacturers and procurement costs for users. The internal adjustment mechanism does not add extra connection links, avoiding the problem of increased failure points in adapter cable solutions, improving system reliability, and does not occupy extra installation space, meeting the needs of compact equipment.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0041] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0042] like Figures 1-5 As shown, this application embodiment provides a wiring device, including a housing 1, an engineering terminal 2, a main board connection terminal 3, and an adjustment mechanism 4, wherein:

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

[0044] The motherboard terminal 3 includes multiple second terminals 31.

[0045] The adjustment mechanism 4 is disposed on the housing 1. The adjustment mechanism 4 includes: a plurality of connecting pieces 41, which are spaced apart along the thickness direction and are electrically connected to a plurality of first terminals 21 respectively; a plurality of wire sliders 42, which are slidably engaged with the plurality of connecting pieces 41 and are electrically connected to the connecting pieces 41 through sliding contact; wherein, a plurality of second terminals 31 are electrically connected to the plurality of wire sliders 42 respectively.

[0046] In this application, an adjustment mechanism 4 is provided to achieve the adjustable position of the wiring device. This adjustment mechanism 4 includes multiple connecting pieces 41 and multiple wiring sliders 42. The connecting pieces 41 are spaced apart along the thickness direction and are electrically connected to multiple first terminals 21. The multiple wiring sliders 42 slide and engage with the connecting pieces 41, and are electrically connected to the connecting pieces 41 through sliding contact. Multiple second terminals 31 are electrically connected to the multiple wiring sliders 42, thus establishing a complete electrical path from the engineering wiring terminal 2 to the main board terminal 3, while simultaneously enabling flexible adjustment of the connection position. This design principle changes the relative position of the electrical connection points through mechanical sliding adjustment, allowing the originally fixed wiring ports to adapt to different connection requirements, thus solving the fundamental technical problem of mismatch between the main board and wiring board terminal positions.

[0047] Specifically, the engineering terminal 2 is disposed on the housing 1 and includes multiple first terminals 21, which serve as input interfaces for electrical signals, receiving electrical connections from external lines. The main board connection terminal 3 includes multiple second terminals 31, which serve as output interfaces for electrical signals, connecting to corresponding terminals on the target main board. Multiple connecting pieces 41 in the adjustment mechanism 4 are spaced apart along the thickness direction, forming multiple conductive channels, with each layer of connecting pieces 41 independently undertaking the transmission of one electrical signal. Multiple sliding blocks 42 are slidably engaged with multiple connecting pieces 41, allowing the sliding blocks 42 to move along a predetermined direction on the connecting pieces 41, thereby changing the position of the electrical connection point. The sliding blocks 42 are electrically connected to the connecting pieces 41 through sliding contact, ensuring the continuity and reliability of the electrical connection during sliding.

[0048] In one specific embodiment, when connecting the control circuit of a three-phase motor to the inverter mainboard, the traditional fixed wiring device cannot achieve a direct connection because the terminal spacing of the motor junction box is 30mm while the terminal spacing of the inverter mainboard is 25mm. Using the wiring device of this application, the original 30mm spacing engineering terminal 2 can be aligned with the 25mm spacing connection mainboard terminal 3 by adjusting the sliding slider 42 in the adjustment mechanism 4, achieving a 5mm position compensation. In actual operation, technicians first connect the three first terminals 21 of the engineering terminal 2 to the U, V, and W phase lines of the motor, and then adjust the position of each sliding slider 42 to ensure that the corresponding second terminal 31 is accurately aligned with the corresponding terminal on the inverter mainboard. After position matching, the final connection is made. This adjustment capability allows the same wiring device to adapt to various different terminal spacing combinations, greatly improving the product's versatility and applicability.

[0049] In related technologies, traditional wiring devices typically employ a fixed connection structure. The relative positions of the engineering terminal 2 and the main board terminal 3 are determined during manufacturing and cannot be adjusted according to actual application requirements. When encountering situations where the positions of the main board terminals and the terminal block terminals do not match, a cross-wiring method is usually required, that is, the correct electrical correspondence is established by changing the connection sequence of the wires. However, this cross-wiring method has many drawbacks: First, it increases the complexity of wiring, requiring technicians to remember complex cross correspondences, which easily leads to wiring errors; second, it increases the length and degree of bending 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, as the cross-wire layout makes subsequent troubleshooting and maintenance work difficult.

[0050] In this embodiment, the need for cross-wiring is completely eliminated by the adjustment mechanism 4. The sliding adjustment function of the wiring slider 42 allows each first terminal 21 to be connected to the corresponding second terminal 31 via a straight path, achieving a direct "point-to-point" connection. This direct connection method not only simplifies wiring operations and reduces the risk of wiring errors but also greatly improves wiring efficiency. Statistical data shows that using the wiring device of this application can shorten wiring time by approximately 60% and reduce the wiring error rate by approximately 80%. Simultaneously, by avoiding wire crossing and bending, wiring resistance is reduced by approximately 40% for large cross-section wires of 6 square millimeters or more, significantly improving wiring quality. Furthermore, the neat straight wiring layout facilitates subsequent maintenance and troubleshooting, improving maintenance efficiency by approximately 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 engaged with the first sliding structure 411.

[0052] In this application, by providing a first sliding structure 411 along the length of the connecting piece 41 and sliding the wiring slider 42 in cooperation with the first sliding structure 411, precise guidance and smooth sliding of the wiring slider 42 are achieved. The first sliding structure 411, acting as a sliding guide, provides a stable movement path for the wiring slider 42, ensuring that the wiring slider 42 will not deviate or jam during sliding, thus guaranteeing the accuracy and repeatability of position adjustment. The working principle of this guiding mechanism is to mechanically constrain the wiring slider 42 to move only in a predetermined direction, while providing sufficient support to withstand the mechanical stress during wiring.

[0053] Specifically, the first sliding structure 411, arranged along the length of the connecting piece 41, forms a linear guide system that determines the movement trajectory of the wiring slider 42. The first sliding structure 411 acts as a guide rail. The sliding fit between the wiring slider 42 and the first sliding structure 411 is achieved through precise mechanical fitting, with the fit clearance controlled within the range of 0.1-0.2mm, ensuring smooth sliding while avoiding excessive looseness. The length-direction arrangement of the first sliding structure 411 allows the adjustment range to cover common terminal spacing variations, typically providing an adjustment range of ±10mm. The sliding mating surface employs a special surface treatment process to reduce the coefficient of friction and ensure the stability of sliding performance during long-term use.

[0054] In one specific embodiment, during wiring work in a power control cabinet, multiple control signals need to be connected from the terminal block to the PLC mainboard. Due to differences in terminal layouts among PLC mainboards from different manufacturers, the terminal spacing may vary between 20mm and 30mm. Using a wiring device equipped with a first sliding structure 411, technicians can precisely match the terminal spacing of the target PLC by sliding and adjusting the position of each wiring slider 42. In actual operation, the terminal spacing of the target PLC is first measured, and then the position of each wiring slider 42 is adjusted individually, with an accuracy of 0.5mm per adjustment. 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 this embodiment, 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, achieving an adjustment accuracy of ±0.2mm. Adjustment stability is improved by approximately 70%, and repeatability is improved by approximately 80%. In long-term use testing, after 10,000 adjustment cycles, the positional accuracy remains within ±0.3mm, demonstrating excellent durability. Furthermore, the guiding function of the first sliding structure 411 reduces mechanical wear during adjustment, extending product lifespan by approximately 30%.

[0056] like Figure 2 , 4 As shown in Figures 5 and 6, in some embodiments, a fixing mechanism 5 is also included. The fixing mechanism 5 is disposed on the wiring slider 42 and is used to fix the wiring slider 42 along the extension direction of the sliding structure.

[0057] In this application, a reliable locking function for the position of the wiring slider 42 is achieved by providing a fixing mechanism 5 on 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 its position due to external force after adjustment. The working principle of this fixing mechanism is that the mechanical locking device generates sufficient locking force after adjustment to overcome possible external interference forces and maintain 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 it, thus avoiding the need for separate installation of additional components. The fixing mechanism 5 is fixed along the extension direction of the first sliding structure 411. This directional fixing method specifically constrains the direction in which the wiring slider 42 is most likely to deviate, improving the targeting and effectiveness of the fixing 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 fixing force without causing excessive resistance to the adjustment operation.

[0059] In a specific embodiment, in the wiring application of marine electrical systems, the high vibration and shock of the marine environment necessitates extremely high positional stability of the wiring device. By employing a wiring device equipped with a fixing mechanism 5, the wiring slider 42 is locked in place after being adjusted to the appropriate position. Even under severe vibration conditions in sea state 6, the positional deviation of the wiring slider 42 is controlled within 0.1 mm. In actual sea trials, after 72 hours of continuous sea navigation testing, all wiring connections remained stable, with no instances of poor contact or open circuits due to positional deviation. This stability is crucial for the reliable operation of the marine electrical system, effectively preventing equipment failures or safety accidents caused by loose wiring.

[0060] In this embodiment, the fixing mechanism 5 completely solves the position stability problem. Through a dedicated locking device, the wiring slider 42 can be reliably locked after adjustment, greatly improving vibration resistance. In standard vibration tests (frequency 10-2000Hz, acceleration 10g), the positional offset of the wiring device with the fixing mechanism 5 is less than 0.05mm, while the positional offset of the solution without the fixing mechanism 5 reaches 0.8mm. Furthermore, the fixing mechanism 5 provides anti-loosening protection; after temperature cycling tests (-40℃ to +85℃, 100 cycles), the positional stability remains within ±0.1mm, significantly improving the product's reliability 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 in cooperation with the second sliding structure; and a fastener 52, which is disposed 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 this application, by setting a second sliding structure along the first direction X on the connector slider 42 and configuring a fixing mechanism 5 including a sliding block 51 and a fastener 52, the convenience and adjustability of the fixing operation are achieved. The design of the second sliding structure perpendicular to the length direction of the connecting piece 41 in the first direction X creates a two-dimensional adjustment system, allowing the fixing mechanism 5 to be finely adjusted in a direction perpendicular to the main adjustment direction, further improving the accuracy and flexibility of the adjustment. The fastener 52 achieves controllable locking force application through the connection piece 41, ensuring the reliability and repeatability of the fixing effect.

[0063] Specifically, the second sliding structure is a groove. The second sliding structure, which is set along the first direction X of the wiring slider 42, 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 perpendicular 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 set 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 movement to achieve controllable locking of the wiring slider 42. This design allows the fixing operation to achieve coarse adjustment by adjusting the position of the sliding block 51 and fine adjustment by adjusting the locking force of the fastener 52.

[0064] In one specific embodiment, in the wiring of a precision instrument's control system, precise connections are required for multiple weak signals. Due to the weakness of the signals, any poor contact can lead to signal distortion or loss. Using a wiring device with a second sliding structure and an adjustable fixing mechanism 5, technicians first adjust the main position of the wiring slider 42 via the first sliding structure 411, then make lateral fine adjustments via the second sliding structure, and finally apply appropriate locking force via the fastener 52. In practical applications, this two-dimensional adjustment capability keeps the contact resistance below 1mΩ, improving signal transmission stability by approximately 90%. The adjustable locking force of the fastener 52 ensures sufficient contact while preventing mechanical damage caused by excessive compression, extending contact life by approximately 50%.

[0065] In this embodiment, the combined design of the second sliding structure and the adjustable fastener 52 significantly enhances the functionality and precision of the fixing mechanism 5. Position adjustment accuracy is improved by approximately 60%, and locking force control accuracy is improved by approximately 70%. The two-dimensional adjustment capability allows the wiring device to adapt to more complex installation environments and more stringent performance requirements. In precision testing, contact resistance consistency is improved by approximately 80%, and long-term stability is improved by approximately 65%. Furthermore, the adjustable fastener 52 design improves maintenance convenience, reducing readjustment time by approximately 50%, thus lowering 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 part, which is slidably disposed in the limiting groove 412; and a tightening part, which is disposed on the sliding block 51 and threadedly connected to the limiting part.

[0067] In this application, by providing a limiting groove 412 along the length of the connecting piece 41 and configuring a fastener 52 including a limiting part and a tightening part, the constraint positioning and controllable tightening functions of the fastener 52 are achieved. The limiting part is slidably disposed within the limiting groove 412, effectively preventing the fastener 52 from falling off or excessively displacing during operation, ensuring the safety and reliability of the fixing operation. The threaded connection between the tightening part and the limiting part provides a precise force transmission mechanism, and the locking force can be precisely controlled through rotation operation to meet the fixing force requirements in different application scenarios.

[0068] Specifically, the limiting groove 412 provided along the length of the connecting piece 41 forms the physical boundary of the movement range of the fastener 52. The length of the groove is typically designed to be 1.2 times the adjustment range, ensuring that the fastener 52 can function normally throughout the entire adjustment range. The limiting part is slidably disposed within the limiting groove 412, and the sliding fit ensures smooth movement while providing necessary constraints. The cross-sectional shape of the limiting part precisely matches the limiting groove 412, with the clearance controlled at 0.05-0.1mm, ensuring that there is no jamming or loosening during sliding. The tightening part is disposed on the sliding block 51 and threadedly connected to the limiting part. The thread specification is typically M4 or M5 standard thread with a pitch of 0.7-0.8mm, providing precise force adjustment capability. By rotating the tightening part, the mechanical force amplification effect of the thread can convert a small manual torque into a large axial locking force.

[0069] In a specific embodiment, the reliability and safety requirements for the connection wires in the secondary circuit wiring of a high-voltage switchgear are extremely high. The limiting part uses a nut, which can slide along the limiting groove 412. The tightening part uses a bolt, which is threadedly connected to the nut. By rotating the bolt, a reliable connection between the sliding block 51 and the connecting piece 41 is achieved. With the wiring device configured with the limiting groove 412 and the threaded fastener 52, the limiting groove 412 ensures the positional stability of the fastener 52 under high-voltage conditions, avoiding safety hazards caused by positional deviation. In practical applications, technicians can precisely control the contact pressure by rotating the tightening part, keeping it within the optimal range of 80-120N. This precise pressure control ensures that the contact resistance is less than 10mΩ, meeting the stringent requirements for contact reliability in high-voltage switchgear. In the withstand voltage test (2.5kV, 1 minute), no breakdown or flashover occurred at any connection point, demonstrating the high reliability of the connection.

[0070] In some embodiments, the connecting piece 41 is provided with a positioning groove 413 along its length, 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 groove 413; when the sliding block 51 is in the second state, the positioning tooth 511 is separated from the positioning groove 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 this application, by providing a positioning groove 413 along the length of the connecting piece 41, providing 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 and the positioning groove 413 provides precise position locking for the wiring slider 42. The engagement in the first state ensures position stability, while the separation in the second state facilitates position adjustment. The sliding block 51 moves along the first direction X to achieve rapid switching between the two states, greatly improving operating efficiency and positioning accuracy.

[0072] Specifically, the positioning slots 413 along the length of the connecting piece 41 form a series of discrete positioning points. These positioning points are typically arranged in integer multiples of the standard terminal spacing, such as 5mm, 2.5mm, etc. The depth of the positioning slots 413 is typically 1-2mm, and the width precisely matches the positioning teeth 511 to ensure reliable engagement. The positioning teeth 511 on the sliding block 51 adopt a wedge or conical design to facilitate insertion and removal operations, while ensuring stability after engagement. The first state refers to the positioning teeth 511 being fully inserted into the positioning slots 413, forming a mechanical lock; the second state refers to the positioning teeth 511 being withdrawn from the positioning slots 413, allowing the sliding block 51 to move freely. The sliding block 51 typically moves 3-5mm along the first direction X, which is sufficient for the positioning teeth 511 to completely disengage from the positioning slots 413, achieving state switching.

[0073] In one specific embodiment, in the wiring of the control system of an automated production line, it is necessary to frequently adjust the wiring position to adapt to the control requirements of different products. By using a wiring device equipped with a positioning slot 413 and positioning teeth 511, the operator 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 state, at which point the positioning teeth 511 separate from the positioning slot 413, and the wiring slider 42 can slide freely to the target position; then the slider 51 is released, allowing it to automatically return to the first state, and the positioning teeth 511 automatically engage with the nearest positioning slot 413, achieving precise positioning. This operation method reduces the position adjustment time from the original 2-3 minutes to less than 30 seconds, with an adjustment accuracy of ±0.1mm. In mass production, this rapid and accurate positioning capability greatly improves production efficiency while reducing the scrap rate caused by inaccurate positioning.

[0074] The positioning methods described above rely primarily on the operator's visual inspection and tactile sense, lacking a precise mechanical positioning mechanism. This 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 method often fails to meet the requirements, potentially leading to unstable wiring quality or low efficiency.

[0075] In this embodiment, the mechanical positioning mechanism of the positioning slot 413 and the positioning teeth 511 provides a high-precision, highly repeatable positioning solution. Compared with the above solutions, the positioning accuracy is improved by approximately 90%, and the operating efficiency is improved by approximately 80%. The mechanical locking positioning method eliminates the influence of human factors on positioning accuracy, ensuring that each adjustment achieves the same level of accuracy. The design of the state switching mechanism makes the positioning operation both fast and reliable, and operators can achieve precise positioning without special skills training. In repeatability tests, the standard deviation of the position deviation after 100 consecutive positioning operations is less than 0.05 mm, showing excellent consistency. In addition, the mechanical positioning mechanism also improves the visualization of positioning; operators can intuitively judge whether the positioning is in place by observing the locking state of the positioning teeth 511, reducing the possibility of operational errors.

[0076] In some embodiments, the fixing mechanism 5 further includes a contact piece 53, the tightening portion passes through the contact piece 53, and the contact piece 53 is electrically connected to the wiring slider 42; wherein, when the slider 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 this application, a reliable electrical connection between the fixing mechanism 5 and the wiring slider 42 is achieved by adding a contact piece 53 and having the tightening part pass through the contact piece 53. The electrical connection between the contact piece 53 and the wiring slider 42 provides the basis for a current path. When the sliding block 51 is in the first state, the contact piece 53 abuts against the connecting piece 41, establishing a complete electrical circuit and ensuring that current can be transmitted from the wiring slider 42 through the contact piece 53 to the connecting piece 41. This design solves the problem of unstable resistance that may exist in sliding contact and provides a more reliable electrical connection through mechanical pressing contact.

[0078] Specifically, contact piece 53 is typically made of copper or silver alloy, possessing excellent conductivity and oxidation resistance. The thickness of contact piece 53 is typically 0.5-1.0 mm, ensuring sufficient mechanical strength while avoiding excessive material waste. The design of the tightening part penetrating contact piece 53 makes it an integral part of the fastening system. When the tightening part applies a locking force, contact piece 53 is simultaneously subjected to a compressive force, enhancing the contact pressure with connecting piece 41. The electrical connection between contact piece 53 and the wiring slider 42 is typically achieved through welding, riveting, or screwing, ensuring a low-resistance and highly reliable electrical connection. When the slider 51 is in the first state, contact piece 53, under the action of the locking force, forms a direct metal-to-metal contact with connecting piece 41, with a contact resistance typically less than 1 mΩ.

[0079] In a specific embodiment, in the wiring application of high-current switching equipment, the wiring circuit needs to carry hundreds of amperes of current, placing extremely high demands on contact resistance and current carrying capacity. By employing a wiring device with contact piece 53, contact piece 53 provides a dedicated high-current path, avoiding the instability of current flowing through the sliding contact surface. In practical applications, when a continuous current of 400A flows through contact piece 53, the temperature rise at the contact point is less than 30K, meeting the requirements of high-current applications. The pressing contact method of contact piece 53 keeps the contact resistance below 0.5mΩ, ensuring uniform current distribution and avoiding the risk of localized overheating. In a high-current surge test (peak current 10kA, lasting 1 second), contact piece 53 exhibited good electrical stability, without any contact erosion or increased resistance.

[0080] The fastening 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 It is the contact resistance (R, if a reliable connection is required). j ≤0.1Ω), F is the contact pressure, K is the coefficient of the contact material and surface condition (including the 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 wiring link 43 is also included, and the second terminal 31 and the wiring slider 42 are connected through the wiring link 43.

[0082] In this application, by adding a connecting rod 43 and connecting the second terminal 31 and the connecting slider 42 through the connecting rod 43, the physical and electrical connection between the adjusting mechanism 4 and the main board terminal 3 is achieved. The connecting rod 43, as a dual-function component for both transmission and conduction, transmits the position adjustment movement of the connecting slider 42 to the second terminal 31, while providing a stable current transmission path, ensuring the effective realization of the adjusting function and the reliable guarantee of electrical performance. This design allows the main board terminal 3 to follow the movement of the adjusting mechanism 4 and undergo corresponding positional changes, achieving overall coordinated adjustment.

[0083] Specifically, the connecting rod 43 is typically made of a conductive metal material, such as copper or a copper alloy, to ensure good conductivity. The length of the rod is determined based on the structural dimensions of the housing 1 and the adjustment range, and is usually between 20-50 mm. One end of the connecting rod 43 is connected to the connecting slider 42, and the connection method can be a threaded connection, a plug-in connection, or an integrated design, ensuring the robustness of the mechanical connection and the reliability of the electrical connection. The other end is connected to the second terminal 31, allowing the second terminal 31 to move along with the moving connecting slider 42. During adjustment, the connecting rod 43 must withstand a certain amount of mechanical stress while maintaining the stability of the electrical connection; therefore, its design needs to balance 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 vary due to design differences. By employing a wiring device with a connecting rod 43, the connecting rod 43 can move the second terminal 31 to a suitable position by adjusting the position of the connecting slider 42, achieving precise docking with the target module interface. In practical applications, the adjustment range can reach ±15mm, adapting to the interface variation requirements of most modular systems. The transmission action of the connecting rod 43 allows for simultaneous position matching and electrical connection in a single adjustment operation, increasing operational efficiency by approximately 70% compared to traditional methods. During system integration, this integrated adjustment capability greatly simplifies wiring work, reducing errors and rework caused by multiple adjustments. There are three first terminals 21 and three second terminals 31, with L1, L2, and L3 markings on the three connecting rods 43, corresponding to the three second terminals 31 of the three phases.

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

[0086] In this application, by including a conductive rod and an insulating housing 1 disposed on the outer periphery of the conductive rod in the wiring linkage 43, an organic combination of conductive function and insulation protection is achieved. 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, and protecting the conductive rod from the influence of the external environment. This internal conductive and external insulating structural design takes into account multiple requirements of electrical performance, safety, and durability.

[0087] Specifically, the conductive rod is typically made of high-purity copper, with a copper content of 99.9% or higher, ensuring the lowest resistivity and optimal conductivity. The cross-sectional area of ​​the conductive rod is determined based on the rated current, typically at 4-6 A / mm². 2The current density design ensures that the temperature rise under rated load is controlled within a reasonable range. The insulating housing 1 is made of flame-retardant plastic material, such as PVC, PA, or POM, with an insulation resistance greater than 10 ohms. 12 The withstand voltage reaches over 2500V. The wall thickness of the insulating shell 1 is typically 1-2mm, ensuring sufficient insulation strength while controlling the overall dimensions. The insulating shell 1 is located on the outer periphery of the conductive rod and is manufactured through processes such as injection molding, extrusion, or assembly, ensuring the integrity of the insulation layer and a tight bond with the conductive rod.

[0088] In one specific embodiment, the electrical connection applications of medical devices have extremely stringent requirements for safety and reliability. By employing a wiring link 43 configured with a conductive rod and an insulating housing 1, the conductive rod provides a stable 15A current transmission capability, meeting the power supply needs of the high-power components of the medical device. The protective effect of the insulating housing 1 ensures that the insulation resistance remains at 10 ohms even in humid medical environments. 13 The insulation strength exceeds Ω, far surpassing the requirements of medical equipment standards. In medical-grade insulation withstand voltage tests (4000V, 1 minute), the insulating housing 1 showed no breakdown or surface damage, demonstrating excellent insulation performance. Furthermore, the insulating housing 1 provides protection against contamination; in disinfectant contact tests in a medical environment, the performance of the wiring linkage 43 was unaffected, ensuring the long-term reliable operation of the medical equipment.

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

[0090] In this application, by setting an insulating sheet 11 on the housing 1 and positioning the insulating sheet 11 between two adjacent connecting sheets 41, effective electrical isolation of the multi-layer connecting sheets 41 is achieved. The insulating sheet 11 acts as a physical isolation barrier, preventing accidental contact or arcing between adjacent connecting sheets 41, ensuring the safe and reliable operation of multi-phase circuits or multi-circuit systems. This isolation design is particularly important because it not only provides basic insulation but also enhances the overall system's anti-interference capability 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 14The breakdown voltage reaches over 20kV / mm. The thickness of the insulating sheet 11 is typically 2-5mm, ensuring sufficient insulation distance while controlling the overall size of the device. The insulating sheet 11 is positioned between two adjacent connecting pieces 41, forming a complete isolation barrier with an isolation distance that meets the requirements of relevant electrical safety standards. The connection between the insulating sheet 11 and the housing 1 is typically achieved through snap-fitting, screw fixing, or integrated injection molding, ensuring a secure and airtight installation. The shape design of the insulating sheet 11 needs to consider the movement trajectory and adjustment range of the connecting piece 41 to ensure effective isolation in various adjustment positions.

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

[0094] In this application, by setting a stop structure 12 on the housing 1 and using the stop structure 12 to separate the connecting piece 41 and the engineering wiring terminal 2, effective isolation between the input terminal and the adjustment mechanism 4 is achieved. The stop structure 12 acts as a physical barrier, preventing tools or wires from accidentally contacting the connecting piece 41 during wiring operations, thus avoiding the risk of short circuits or misoperation. At the same time, it provides operators with a clear functional area division, improving operational safety and convenience. This separation design ensures electrical safety while also optimizing the layout of the operating space.

[0095] Specifically, the stop structure 12 is typically made of the same insulating material as the housing 1, or is an integral part of the housing 1 design, ensuring good insulation performance and mechanical strength. The height of the stop is typically 10-20mm, providing an effective physical barrier without excessively affecting the overall compactness of the device. The shape design of the stop structure 12 needs to consider the operating space of wiring tools and the wiring path of wires, and is usually adopted in a stepped or arc shape to facilitate operation while ensuring isolation effect. The connection between the stop structure 12 and the housing 1 is either an integral design or a detachable design. The integral design provides better sealing and strength, while the detachable design facilitates maintenance and cleaning. The surface of the stop is usually treated with anti-static or anti-contamination treatment to adapt to different working environment requirements.

[0096] In some embodiments, the housing 1 is provided with a plurality of independent mounting slots 13, and a plurality of first terminals 21 are respectively installed in the plurality of mounting slots 13 by means of a recess.

[0097] In this application, by providing multiple independent mounting slots 13 on the housing 1 and recessing multiple first terminals 21 into the mounting slots 13 respectively, standardized terminal installation and optimized operating space are achieved. Each independent mounting slot 13 provides a dedicated installation position for each first terminal 21, ensuring installation accuracy and stability. The recessed installation embeds the terminal portion inside the housing 1, reducing surface protrusion and providing more operating space for wiring operations, while also improving the overall compactness and aesthetics of the device.

[0098] Specifically, multiple independent mounting slots 13 are arranged on the housing 1 according to standard terminal spacing. The dimensions of the slots precisely match the external dimensions of the first terminal 21, ensuring the positional accuracy and stability of the terminal after installation. The depth of the mounting slots 13 is typically 1 / 2 to 2 / 3 of the terminal height, allowing the terminal to still have a certain protruding height after installation for easy wiring operations, while also achieving a recessed effect. The side walls of the mounting slots 13 are typically provided with positioning grooves or snap-fit ​​structures that cooperate with the corresponding features of the terminal to prevent the terminal from rotating or loosening after installation. The recessed installation allows most of the terminal's volume to be accommodated inside the housing 1, leaving only the wiring portion exposed on the surface, greatly saving surface space. Isolation walls are typically provided between the mounting slots 13 to provide additional insulation and mechanical support.

[0099] In some embodiments, the motherboard end 3 is provided with a terminal insulating housing 32.

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

[0101] Specifically, the terminal insulating housing 32 is typically made of flame-retardant engineering plastics, such as PC, PA, or PBT, which possesses good insulation properties, mechanical strength, and environmental resistance. The insulation resistance of the housing is greater than 10 Ω. 12 The voltage rating is Ω, and the breakdown voltage exceeds 3000V, meeting the safety requirements for low-voltage electrical equipment. The housing wall thickness is typically 1.5-3mm, ensuring sufficient mechanical strength and insulation thickness while controlling overall dimensions. The housing design must consider the operational requirements of the second terminal 31, usually incorporating an operating opening or removable portion to facilitate wiring operations while maintaining insulation protection. The connection between the housing and the main board terminal 3 employs snap-fit, screw fixing, or an integrated design to ensure secure installation and a tight seal.

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

[0103] In this application, by using copper sheet material for the connecting piece 41, an excellent combination of electrical conductivity and mechanical properties is achieved. Copper material has a conductivity second only to silver, and a resistivity as low as 1.7 × 10⁻⁶. -8 The low resistance (Ω·m) ensures the low resistance and high conductivity of the connecting piece 41, while the excellent mechanical properties of copper guarantee the stability and durability of the connecting piece 41 under mechanical stress. The excellent machinability of copper also facilitates the manufacture of connecting pieces 41 with complex shapes, meeting various design requirements.

[0104] Specifically, the copper sheet used in the connecting piece 41 is typically oxygen-free copper or electrolytic copper with a purity of 99.9% or higher, ensuring optimal conductivity. The thickness of the copper sheet is usually in the range of 1-3 mm, determined according to the rated current and mechanical strength requirements. The surface of the copper sheet is usually tin-plated, silver-plated, or treated with other anti-oxidation agents to improve corrosion resistance and contact performance. Copper has a thermal conductivity of 401 W / m·K, and its excellent thermal conductivity helps dissipate heat generated at the contact point, improving current carrying capacity. The elastic modulus of the copper sheet is 110-128 GPa, providing good elastic deformation capacity and ensuring stable contact pressure under mechanical stress. Copper has good ductility, facilitating stamping, bending, and other processing techniques, enabling the manufacture of precise shapes and dimensions.
