These precision electronic components require stable and reliable power connection guarantees during the testing, aging screening and final application stages of the manufacturing process.

[0003] A search revealed that patent document CN115528627A discloses an intelligent anti-loosening high-voltage wire clamp, which includes a clamping arm at both ends of the clamp body. The two clamping arms are fixedly connected by fastening bolts. An anti-loosening device is installed on the outside of the two clamping arms. The anti-loosening device is also connected to a metal fixing band, which is electrically connected to a current transformer. This invention not only improves safety protection but also facilitates emergency repairs and maintenance.

[0004] The aforementioned existing technologies often have the following problems when used:

[0005] Existing high-voltage clamping hardware faces numerous problems during use. First, due to factors such as line vibration, wind force, and temperature changes, mechanical loosening is prone to occur, leading to increased contact resistance and localized overheating. Second, frequent start-ups and shutdowns of power electronic equipment and load changes generate significant electrical and thermal stresses in the line, accelerating the loosening process of the hardware. Furthermore, traditional hardware lacks effective anti-loosening automatic adjustment functions and intelligent monitoring functions, requiring regular manual inspection and maintenance, which increases operation and maintenance costs. Therefore, corresponding solutions are needed. Summary of the Invention

[0007] To achieve the above objectives, the present invention provides the following technical solution:

A pressure sensor is fixedly installed on the inner top surface of the housing. An arc-shaped pressure plate is provided on the side of the inner arc clamping block.

Two No. 3 springs are fixedly connected between the upper end surface of the arc-shaped pressure plate and the bottom surface of the housing. An upper pressure plate is fixedly connected to the top of the two No. 2 guide rods.

[0014] According to the above-mentioned anti-loosening high-voltage wire clamp fitting, the side-end adjustment assembly includes a second groove formed on the upper surface of the inner arc clamping block.

The No. 3 spring is sleeved on the No. 2 guide rod. The two screw locking assemblies are respectively fixedly installed on both sides of the No. 1 threaded rod. In the locking opening and closing assembly, the two inclined moving blocks are respectively located on both sides of the trapezoidal moving block and are symmetrically arranged about it.

[0016] According to the above-mentioned anti-loosening high-voltage clamp electrical fitting, the temperature sensor, motor number one, electric push rod and alarm light are all electrically connected to the PLC controller, and the circuit formed by the temperature sensor, motor number one, electric push rod, alarm light and PLC controller is electrically connected to an external power supply.

[0017] According to the above-mentioned anti-loosening high-voltage clamping electrical fitting, the pressure sensor and the second motor are both electrically connected to the PLC controller, and the circuit formed by the pressure sensor, the second motor and the PLC controller is electrically connected to an external power supply.

[0018] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0019] 1. This invention, through its automatic adjustment component, can intelligently control the operation of motor number one based on real-time temperature data monitored by a temperature sensor and via a PLC controller. This drives the worm gear mechanism to precisely raise and lower the threaded rod number one, thereby achieving automatic adjustment of the wire clamping force. This effectively compensates for connection loosening caused by thermal expansion and contraction, ensuring that the connection point maintains optimal compression. Furthermore, through the coordinated operation of the temperature sensor, PLC controller, and alarm light, it can achieve real-time monitoring of the connection point temperature and provide over-temperature alarm.

[0020] 2. The present invention, through the screw locking assembly, enables the locking teeth to act directly on the first threaded rod. The locking teeth arranged symmetrically on both sides form a bidirectional locking force. After the first threaded rod completes the lifting and lowering adjustment, it can immediately achieve stable and reliable mechanical locking, effectively preventing the threaded rod from reversing or displacing due to external forces such as vibration and impact, and ensuring that the clamping force remains stable for a long time.

[0021] 3. This invention, through its locking and opening / closing assembly, enables the moving plate to rise and fall via an electric push rod, thereby driving the trapezoidal moving block to move up and down. This achieves intelligent switching of the locking state. When locking is required, the electric push rod is in the closed state, and the second spring pushes the trapezoidal moving block downwards, causing the two inclined moving blocks to move away from each other. This causes the arc-shaped rubber pad to fit tightly against the side wall of the guide post, generating sufficient friction to prevent the moving seat from moving. This keeps the locking teeth in a fixed position, achieving reliable locking of the first threaded rod. When unlocking is required, the extension of the electric push rod overcomes the elasticity of the second spring, pulling the trapezoidal moving block upwards. This causes the two inclined moving blocks to move towards each other under the action of the spring, causing the arc-shaped rubber pad to separate from the guide post, eliminating the constraint on the moving seat, and thus creating the necessary conditions for adjusting the position of the locking teeth.

[0022] 4. The present invention, through the side loosening sensing component, can monitor the lateral pressure of the inner arc pressure block on the wire in real time through the pressure sensor. When the pressure value is lower than the set threshold, it immediately sends a signal to the PLC controller, providing accurate data support for automatic adjustment and realizing early warning of loosening phenomenon.

[0023] 5. The present invention, through the side-end adjustment component, can drive the second threaded rod to rotate via the second motor after receiving a loosening signal, thereby causing the adjustment block to move precisely along the third guide rod, realizing fine-tuning compensation of the position of the inner arc pressure block, thus ensuring that the clamping force is always kept within a safe range and effectively achieving the anti-loosening function.

[0040] The side adjustment assembly 6 includes a second groove 61 formed on the upper surface of the inner arc pressure block 13. Two third guide rods 62 are fixedly connected between the inner walls of the second groove 61. Adjustment blocks 63 are slidably sleeved on the two third guide rods 62. A threaded sleeve 64 is hinged to the upper surface of the adjustment block 63. A second threaded rod 65 is threadedly connected to the inner thread of the threaded sleeve 64. The second threaded rod 65 is rotatably connected to the upper surface of the lower pressure plate 26 through a bearing. A second motor 66 is fixedly connected to the upper surface of the lower pressure plate 26 through a bracket. The output end of the second motor 66 is fixedly connected to the top end of the second threaded rod 65. Protective covers are fixedly installed on the outside of the first motor 21 and the two second motors 66, which can provide good protection for the motors. The pressure sensor 52 and the second motors 66 are electrically connected to the PLC controller 29. The circuit formed by the pressure sensor 52, the second motors 66 and the PLC controller 29 is electrically connected to an external power supply.

[0041] The working principle of this invention is as follows: In the initial state, the electric push rod 48 is in the retracted state, the second spring 47 pushes the trapezoidal moving block 44 to the lower limit position, and the two inclined moving blocks 42 expand outward under the action of the inclined surface, causing the arc-shaped rubber pad 49 to fit tightly against the side wall of the guide column 33, generating sufficient static friction to restrict the movement of the moving seat 34. At this time, the locking tooth 37 and the first threaded rod 25 maintain a stable engagement state, and the entire system is in the locked state.

[0042] In use, the high-voltage wire to be clamped is first placed between the inner arc clamping block 13 and the arc groove at the bottom of the hardware frame body 1. The clamping program is started. The PLC controller 29 first controls the electric push rod 48 to extend. The trapezoidal moving block 44 is pulled up by the moving plate 46 and the first guide rod 45. The inclined moving block 42 moves towards each other under the action of the first spring 43, which drives the arc rubber pad 49 to separate from the guide column 33, releasing the constraint on the moving seat 34. Then the first motor 21 is started to rotate. The worm gear 22 drives the worm wheel 23 to rotate slowly, which drives the first threaded rod 25 to move down smoothly. The lower pressure plate 26 pushes the inner arc clamping block 13 to slide down synchronously along the clamping guide groove 12 to achieve the initial clamping of the wire.

[0043] When the inner arc pressure block 13 contacts the wire, the system enters the pressure precision control stage. The pressure sensor 52 monitors the clamping pressure in real time. When the pressure value reaches the preset range, the PLC controller 29 controls the first motor 21 to stop rotating. At this time, the electric push rod 48 automatically retracts, the locking mechanism returns to the locking state, and the locking tooth 37 re-engages with the first threaded rod 25 to prevent the threaded rod from reversing.

[0044] During operation, external factors such as mechanical vibration, wind force, or temperature changes can easily cause changes in the clamping tightness of the fittings on the high-voltage wire. When the clamping force is insufficient, the contact area between the high-voltage wire and the inner arc clamping block 13 decreases, resulting in a significant increase in contact resistance. According to Joule's law, when a large current passes through, the increased contact resistance will generate a large amount of Joule heat, thus causing local overheating at the connection. At this time, the temperature sensor 28 installed in the first cavity 27 inside the inner arc clamping block 13 continuously monitors the temperature change at the connection. When the temperature exceeds the preset safety threshold, the temperature sensor 28 immediately transmits the signal to the PLC controller 29. The PLC controller 29 will start the loosening compensation program. The PLC controller 29 first controls the electric push rod 48 to extend, which drives the trapezoidal moving block 44 to move upward through the moving plate 46 and the first guide rod 45. The inclined surface of the trapezoidal moving block 44 interacts with the two inclined side moving blocks 42, causing the inclined side moving blocks 42 to move upward under the elastic force of the first spring 43. The opposing movements cause the arc-shaped rubber pad 49 to separate from the guide post 33, releasing the constraint on the moving seat 34 and opening the locking state. Then, based on the temperature change, the clamping force that needs to be adjusted is determined, and the first motor 21 is controlled to rotate at a certain angle. The first motor 21 starts and drives the worm wheel 23 to rotate through the worm gear 22. The internal thread 24 of the worm wheel 23 interacts with the first thread rod 25, causing the first thread rod 25 to produce a precise axial displacement, which drives the lower pressure plate 26 to push the inner arc pressure block 13, realizing the automatic adjustment of the wire clamping force. After the adjustment is completed, the PLC controller 29 controls the electric push rod 48 to retract. Under the action of the second spring 47, the trapezoidal moving block 44 moves down, pushing the two inclined moving blocks 42 to move in opposite directions, so that the arc-shaped rubber pad 49 is tightly attached to the guide post 33 again, generating sufficient friction to lock the position of the moving seat 34. At this time, the locking tooth 37 and the first thread rod 25 re-form a stable engagement state, ensuring that the adjusted position will not be changed by external force, and the locking mechanism is activated again.

[0045] Based on the above adjustments, the loosening of the fittings also includes uneven clamping force on both sides. In this case, it is necessary to use the side loosening sensing component 5 and the side adjusting component 6 to compensate for the loosening. Under the action of the third spring 55, the two arc-shaped pressure plates 53 will always be in contact with the surface of the high-voltage wire. The upper pressure plate 56, driven by the arc-shaped pressure plates 53, will press the pressure sensor 52, thereby converting the clamping tightness of the fittings into the pressure value of the pressure sensor 52. When the pressure sensor 52 detects that the clamping force is lower than the safety threshold, it indicates that there is a loosening phenomenon on one side. The PLC controller 29 will immediately start the secondary adjustment program, control the second motor 66 to run, and drive the adjusting block 63 to move through the second threaded rod 65, changing the clamping angle of the inner arc pressure block 13 to achieve precise compensation of the clamping force. When the clamping force is detected to return to the safety threshold range, the PLC controller 29 will immediately stop the operation of the second motor 66. The whole process does not require manual intervention and realizes fully automatic intelligent adjustment.

[0046] If the system detects a continuous abnormal temperature or pressure, the PLC controller 29 will activate the alarm light 210 and issue an audible and visual alarm signal to remind maintenance personnel to carry out timely maintenance.
