Description

Technical Field

[0001] This utility model relates to the field of wire insulation testing equipment, specifically a quick-installation wire fixing device. Background Technology

[0002] During the manufacturing process of electrical wires, factors such as raw material issues and manufacturing defects may lead to poor insulation performance. If the insulation resistance of the wire is too low, leakage may occur during use, resulting in electric shock or even an electrical fire. Insulation resistance is a key indicator of wire quality; therefore, insulation resistance testing is necessary at the end of the wire production process to understand the quality and performance of the wire's insulation layer.

[0003] Insulation resistance testing of electrical wires requires the use of an insulation resistance tester. Currently, there are many types of commonly used insulation resistance testers. For example, a Chinese patent with publication number CN208156082U discloses an insulation tester that includes an external tester chassis and an internal control unit. The control unit includes an input channel module, a data processing module, a control processor, a display module, a button module, a storage module, and a communication module. The input channel module is connected to the data processing module, and the output of the data processing module is connected to the control processor. The control processor is connected to the display module, the button module, the storage module, and the communication module. This patent's internal control unit has a simple structure, enabling rapid testing of the insulation resistance of railway signal cables to ground and between lines, and providing quick display of the results.

[0004] When using the insulation resistance tester provided in the aforementioned patent or other types of insulation resistance testers to test the insulation resistance of wires, the line terminal (“L”) of the insulation resistance tester needs to be connected to the conductor portion of the wire; that is, if it is a single-core wire, the “L” terminal should be connected to that core wire. The grounding terminal (“E”) should be connected to the grounding device or the shielding layer of the wire. After confirming that the test leads are connected correctly and the test parameters are set correctly, press the “Test” button on the tester to start the insulation resistance test. At this time, the tester will automatically output the selected DC voltage and measure the leakage current through the insulation layer of the wire, thereby calculating the insulation resistance value and displaying it on the display screen in real time.

[0005] While the above operation can test the insulation capacity of wires, it has some drawbacks. For example, the operation requires a high degree of manual intervention; when testing the insulation of each wire, personnel often need to clamp the conductive clamp onto the wire before starting the insulation resistance tester. If testing batches of wires, this operation is time-consuming and labor-intensive, and there is a high risk of injury due to insufficient protective measures (not wearing insulated gloves and shoes, or damaged insulated gloves and shoes).

[0006] If the insulation resistance tester can be equipped with a corresponding wire fixing structure and the conductive clamp can be made to work automatically, the safety of wire insulation testing will be improved, and the testing of batch wires will be accelerated. Utility Model Content

[0033] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0034] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0035] like Figure 1As shown, in order to reduce the manual intervention required for wire insulation testing and improve the testing efficiency of batch wires, this embodiment provides a new wire insulation testing device. This device includes an insulation tester 1 and two sets of connecting mechanisms 6. The two sets of connecting mechanisms 6 are connected to the insulation tester 1 via wires and are respectively connected to the conductor and insulator of the wire. Therefore, the insulation performance of the wire can be tested while the insulation tester 1 is operating. Furthermore, the connecting mechanisms 6 can be moved and clamped without manual intervention. Therefore, after workers have neatly arranged a batch of wires, the connecting mechanisms 6 can complete the insulation performance testing of each wire individually, thereby reducing the need for manual intervention, lowering the risk of accidents, and improving the testing efficiency of batch wires.

[0036] like Figure 6 , Figure 8 As shown, specifically, the insulation tester 1 is detachably mounted on the support plate 12. The bottom of the support plate 12 is adjustablely inserted into the base tube 41, and the base tube 41 is mounted on the edge of the base 11. Multiple sets of fixing components 2 are also installed on the base 11. Additionally, two sets of connecting mechanisms 6 are adjustablely mounted on the base tube 41 and distributed on both sides of the multiple sets of fixing components 2. Therefore, the operator can place the wires to be tested one by one on the multiple sets of fixing components 2 and fix the wires using the fixing components 2. This allows the connecting mechanisms 6 to move to the side of the wire and clamp the wire conductor or insulator, providing support for the insulation capacity test of the wires by the insulation tester 1.

[0037] The insulation tester 1 described above is an existing device, which will be briefly introduced here. The insulation tester 1 includes a power supply section, a voltage boosting section, a measurement circuit, a control section, a display circuit, a protection circuit, a housing, and accessories.

[0038] The power supply section includes the battery and power management circuitry. The battery typically uses multiple AA batteries or rechargeable batteries as its internal power source, providing the instrument with the necessary electrical energy for operation; for example, a common configuration is eight AA high-capacity rechargeable batteries. The power management circuitry monitors and manages the battery voltage, promptly alerting the user to replace or recharge the battery when the voltage is low. It also supports both AC and DC power, prioritizing AC power when connected and converting and regulating the input AC power to meet the operational requirements of the instrument's internal circuitry.

[0039] The step-up section includes a voltage regulating transformer and a step-up transformer. The voltage regulating transformer converts the input mains voltage (e.g., 220V) into a primary voltage suitable for the step-up transformer. By adjusting its output voltage, the final test voltage applied to the object under test can be controlled. The step-up transformer increases the lower voltage output from the voltage regulating transformer to the required test voltage level, such as 500V, 1000V, 2000V, 2500V, etc., to meet the requirements of different insulation resistance measurements.

[0040] The measurement circuit includes a current sampling circuit, an I / V conversion circuit, and a divider. The current sampling circuit measures the leakage current through the insulation resistance being measured, converting the current signal into a voltage signal for subsequent processing and measurement. The I / V conversion circuit converts the weak current signal obtained from the current sampling circuit into a proportional voltage signal for analog-to-digital conversion and digital processing. The divider calculates the resistance value of the insulation resistance being measured based on the measured voltage signal and the known test voltage through division, and transmits the result to the display circuit.

[0041] The control unit includes a microprocessor, buttons, and switches. The microprocessor, as the core of the instrument's control, coordinates the work of various components, such as controlling the voltage boosting process, data acquisition, processing, and display, as well as implementing functions like automatic range switching, timing, and data storage. The buttons and switches include a power switch, voltage selection switch, and test start / stop switch, used by the user to operate the instrument, enabling functions such as powering on / off, selecting test voltage levels, and starting and stopping tests.

[0042] The display circuit is set to an LCD screen to intuitively display the measurement results, including insulation resistance value, test voltage, test time, battery status, alarm information, etc., so that users can easily read and record test data.

[0043] The protection circuit includes overcurrent protection and overvoltage protection. The overcurrent protection circuit quickly cuts off the power supply to the boost circuit when the current in the circuit under test exceeds a set value, preventing damage to the instrument and the device under test due to overcurrent. The overvoltage protection circuit activates immediately during the boost process if an abnormal voltage increase occurs, protecting the internal circuitry of the instrument and the device under test from excessive voltage surges.

[0044] The outer casing is typically made of high-strength aluminum alloy or similar materials, possessing excellent mechanical strength and electromagnetic shielding properties. It protects the internal circuitry from external environmental interference and damage, while also providing dustproof, moisture-proof, and shockproof functions. Test leads and clips connect the tester to the object under test, ensuring the test current accurately passes through the insulation resistance being measured. The clips are generally made of metal, possessing good conductivity and clamping force, allowing them to firmly attach to the object under test and guaranteeing the reliability of the test connection. In this embodiment, the clips are part of the connection mechanism 6, which will be described in detail below.

[0045] like Figure 7As shown, in order to achieve a detachable connection between the insulation tester 1 and the support plate 12, a top plate 13 is fixedly installed on the top of the support plate 12. A first clamping plate 14 and a second clamping plate 15 are bolted to both sides of the top plate 13. The first clamping plate 14 and the second clamping plate 15 cooperate to clamp the bottom of the insulation tester 1. Therefore, with the cooperation of the first clamping plate 14 and the second clamping plate 15, the insulation tester 1 can be stably installed relative to the support plate 12, while providing convenience for disassembling the insulation tester 1 as needed.

[0046] like Figure 8 As shown, in order to stably and adjustably mount the connecting mechanism 6 on the base 11, a support frame 4 is provided between the support plate 12 and the base 11. This support frame 4 includes a bottom tube 41, a lifting plate 45, and two movable plates 44. The bottom of the bottom tube 41 is bolted to the base 11. The lifting plate 45 is vertically mounted on the side of the bottom tube 41, and a sleeve 43 is fixedly mounted in the middle. The sleeve 43 is fitted onto the bottom tube 41 and threaded onto a second threaded rod 42. The bottom of the second threaded rod 42 is connected to a second motor via a coupling. Therefore, the rotation of the second threaded rod 42 can be controlled when the second motor is operating, thereby adjusting the positions of the sleeve 43 and the lifting plate 45, providing initial support for adjusting the position of the connecting mechanism 6.

[0047] like Figure 8 As shown, the ends of the two movable plates 44 that are close to each other are inserted into the lifting plate 45. Therefore, when the lifting plate 45 rises and falls, the movable plates 44 move synchronously. In addition, in order to control the movement of the movable plates 44 relative to the lifting plate 45 and to adjust the position of the connecting mechanism 6 again, a double-headed motor is provided on the lifting plate 45. A third threaded rod is provided on each of the two output shafts of the double-headed motor. The third threaded rod is threaded through the movable plates 44. Therefore, when the double-headed motor is working, the movement of the movable plates 44 relative to the lifting plate 45 can be controlled.

[0048] like Figure 9 As shown, in order to enable the connecting mechanism 6 to move more flexibly and to detect the insulation capacity of the wire, end tubes 46 are provided at the ends of the two movable plates 44 that are far apart from each other. Through holes are provided on the side walls of the end tubes 46, and connecting plates 53 are installed through the end tubes 46. A rack 52 is provided on the side wall of the connecting plate 53. A second motor is installed on the end tubes 46, and a gear 51 is provided on the output shaft of the second motor. The gear 51 passes through the through holes and meshes with the rack 52. Therefore, when the second motor is working, the position of the connecting plate 53 relative to the end tubes 46 can be adjusted by rotating the gear 51. The gear 51, rack 53, and connecting plate 53 constitute the connecting assembly 5.

[0049] like Figure 10As shown, the above-described configuration enables adjustment of the position of the connecting mechanism 6. Therefore, the frame of the connecting mechanism 6 is bolted to the end of the connecting plate 53. Furthermore, the connecting mechanism 6 includes a telescopic cylinder 61 (which can be an electric cylinder), two connecting arms 62, and two guide plates 63. The two connecting arms 62 are hinged to the frame via a central shaft, bearings, etc., with one end hinged to the telescopic end of the telescopic cylinder 61 and the other end connected to the two guide plates 63. Therefore, when the telescopic cylinder 61 is working, the connecting arms 62 can be controlled to rotate around the axis, thereby adjusting the position of the guide plates 63. Thus, the two guide plates 63 can fit against and clamp the conductor or insulator of the wire, acting as clamps. Additionally, the guide plates 63 are connected to the insulation tester 1 via wires, thus allowing the insulation tester 1 and the wire to form a circuit, thereby enabling the testing of the wire's insulation capacity.

[0050] As can be seen from the above technical solution, with the cooperation of multiple motors, threaded rods, and telescopic cylinders, the guide plate 63 can move in space, providing convenience for automatically completing the insulation capacity test of batch wires. In addition, to reduce the resistance to the relative movement of the contacting devices, the smoothness of the contact surface can be improved, and lubricating oil can be added to the contact surface, or the above-mentioned devices can be made of materials with a low coefficient of friction (such as polytetrafluoroethylene).

[0051] To achieve the orderly movement of the guide plate 63, the motor (which can be set as a stepper motor), the telescopic cylinder, and the microprocessor can be connected, or connected to other controllers (such as a PLC). This controller and the microprocessor are then connected to the same host computer (such as a computer). The connection methods between the motor, telescopic cylinder, and PLC have been disclosed. For example, the PLC's pulse output terminal (such as the high-speed pulse output point of a transistor output type PLC) is connected to the pulse input (PUL) terminal of the stepper motor driver. This is the key signal for controlling the stepper motor's rotation angle; the PLC precisely controls the motor's step angle and number of rotations by sending pulses of a certain frequency and number. Another digital output terminal of the PLC is connected to the direction (DIR) terminal of the stepper motor driver. This signal controls the motor's rotation direction; when the digital output terminal outputs a high level, the motor rotates forward; when it outputs a low level, the motor rotates in the reverse direction. The PLC's analog output terminal (for analog-controlled electric cylinders) or high-speed pulse output terminal (for electric cylinders using pulse control) can be connected to the position control input port of the electric cylinder controller.

[0052] Alternatively, an RS-232 communication cable can be used to connect the RS-232 interface of the PLC / microprocessor to the COM port of the computer. The corresponding serial communication software needs to be installed on the computer, and the communication parameters, such as baud rate, data bits, stop bits, parity, etc., need to be set to be consistent with the communication parameters of the PLC / microprocessor. Then, the motor, telescopic cylinder, and insulation tester 1 can work together on the host computer.

[0053] like Figure 2 As shown, when the guide plate 63 can move in space, in order to place a batch of wires stably, multiple sets of fixing components 2 need to be set on the base 11. The multiple sets of fixing components 2 are evenly divided into multiple groups, and the multiple groups of fixing components 2 are installed on the bracket 3. The multiple sets of fixing components 2 in each group are arranged vertically at intervals. Therefore, the batch of wires can be neatly distributed above the base 11 under the action of the fixing components 2 so that the guide plate 63 can clamp and form a circuit with the insulation tester 1.

[0054] like Figure 4 , Figure 5 As shown, in order to stably place the wire under the action of the fixing component 2, the fixing component 2 includes a support plate 25 and a pressure plate 24. The pressure plate 24 is located above the support plate 25, and the sides of the plates that are close to each other are all set as arc surfaces. Each pressure plate 24 in the group has a first threaded rod 21 threaded through its side. Adjacent first threaded rods 21 are connected to a drive shaft 22 by a coupling. The first threaded rod 21 on the bottom side is connected to a first motor 23 by a coupling. The first motor 23 is mounted on the bracket 3. Therefore, when the first motor 23 is working, it can control the synchronous lifting and lowering of multiple pressure plates 24 in the same group, thereby cooperating with the support plate 25 to stably clamp the wire and place it stably.

[0055] like Figure 3 As shown, to ensure stable installation of multiple sets of fixing components 2, the bracket 3 includes multiple vertical plates 31. A base plate 33 is positioned below each vertical plate 31. Adjacent base plates 33 have insert plates 34 and slots 35 at their ends. The insert plates 34 are inserted into the slots 35, enabling adjustable connection between adjacent vertical plates 31 and facilitating adjustment of their positions as needed. The ends of the multiple interconnected base plates 33 are connected to the base 11 via bolts, ensuring a stable connection between the entire bracket 3 and the base 11.

[0056] like Figure 3 , Figure 5 As shown, multiple vertical plates 31 are adapted to multiple sets of fixing components 2 one by one. Multiple through holes 32 are provided on the vertical plates 31, and the multiple through holes 32 are arranged along the height direction of the vertical plates 31. Sleeves 26 are fixedly provided on the sides of the support plate 25 and the pressure plate 24. The sleeves 26 are sleeved on the vertical plates 31. Bolts are provided through the sleeves 26 of the support plate 25 and through the through holes 32. Therefore, the support plate 25 is stably installed on the side of the vertical plate 31. A driving plate 27 is fixedly provided on the side of the sleeves 26 of the pressure plate 24. The first threaded rod 21 is threaded through the driving plate 27.

[0057] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
