Description

Technical Field

[0001] This application relates to the field of wire performance testing technology, and in particular to a wire bending resistance test device. Background Technology

[0002] As a crucial carrier for power transmission and signal transmission, the durability of electrical wires directly affects the safety and reliability of electrical equipment. With the widespread use of electronic devices and the increasing complexity of power systems, higher requirements are being placed on the bending resistance of electrical wires.

[0003] Currently, the industry mainly uses manual bending or simple mechanical devices to test the bending resistance of wires, but the testing accuracy and efficiency are low, making it difficult to meet the needs of large-scale production. In recent years, automated testing technology has been gradually applied to the field of wire performance testing, but dedicated testing equipment for bending resistance still cannot achieve efficient and accurate testing. Utility Model Content

[0004] To improve the accuracy and efficiency of wire bending resistance testing, this application provides a wire bending resistance testing device with the following technical solution: A wire bending resistance testing device includes a housing, a clamp, two terminals, a counter, and a repetitive bending drive mechanism. The two terminals are disposed on the surface of the housing for connecting the positive and negative poles at both ends of a wire. The clamp is used to detachably fix the wire portion connected to the terminals. The repetitive bending drive mechanism includes a push block for connecting and pushing the wire, and a drive assembly for driving the push block to move back and forth towards or away from the clamp. The drive assembly is connected to a power source via the two terminals, allowing the drive assembly to drive the push block to move back and forth. The housing is equipped with a proximity sensor, which is electrically connected to the counter. During the repetitive movement of the push block, the proximity sensor can be triggered to send a trigger signal to the counter, causing the counter to count.

[0005] By adopting the above technical solution, the wire passes through the push block and is then fixed to the terminal clamp. The positive and negative terminals at both ends of the wire are connected to two terminals. The terminal clamp keeps the wire between the wire and the terminal in a fixed and immovable state, thus ensuring a stable connection between the wire and the terminal. The wire between the push block and the terminal clamp can bend freely. The drive component is powered on after being connected to the terminal. When powered on, the drive component drives the push block to move back and forth towards or away from the terminal clamp to bend the wire. Each reciprocation triggers a proximity sensor to send a signal to a counter for counting, until the wire breaks, causing the drive component to be de-energized, thus completing the test of the number of wire bends, thereby improving the accuracy and efficiency of the test.

[0006] Preferably, the wiring clamp includes a fixed base, a locking member, and a clamping block. The fixed base is fixed to the housing; the clamping block is located on the upper surface of the fixed base; the locking member is rotatably connected to the clamping block and simultaneously threadedly connected to the fixed base.

[0007] By adopting the above technical solution, the fixed base is fixed to the housing, ensuring a stable connection between the bottom of the wire clamp and the housing, and preventing the wire clamp from sliding during device operation; the clamp block is set on the upper surface of the fixed base, and the locking member is rotatably connected to the clamp block and simultaneously threaded to the fixed base, which improves the connection stability between the clamp block and the fixed base and reduces the risk of the wire slipping or falling out in the clamp block during testing.

[0008] Preferably, the locking element is a wing screw.

[0009] By adopting the above technical solution and using a wing screw, operators can easily insert the wire by manually turning the wing screw before the wire bending experiment or when the clamp is open. Furthermore, if the clamp and the fixed seat become loose, the tightness of the clamp and the fixed seat can be adjusted by manually turning the wing screw to fix the clamp and the fixed seat in place.

[0010] Preferably, the upper surface of the fixing base has two receiving grooves for placing wires.

[0011] By adopting the above technical solution, the wire can be inserted into the receiving groove, which can reduce the risk of the wire being damaged by pressure due to the fixed connection between the clamp and the fixing seat.

[0012] Preferably, the drive assembly includes a motor, a connecting rod, a push rod, and a guide block. The motor is connected to a power source via wires and terminals. The output shaft of the motor is connected to one end of the connecting rod. The other end of the connecting rod is connected to the push rod. The end of the push rod is fixedly connected to the push block. The guide block is fixed to the housing. The push rod movably passes through the guide block. The motor drives the connecting rod to move the push rod through the guide block, causing the push block to reciprocate in a straight line.

[0013] By adopting the above technical solution, after power is applied, the motor drives the connecting rod to start moving. The push rod connected to the connecting rod moves back and forth along the direction of approaching the terminal clamp under the guidance of the guide block. As the push block on the push rod approaches the terminal clamp, it triggers the proximity sensor. The proximity sensor recognizes and sends a signal to the counter to start counting until the wire breaks, the drive component is powered off, and the experimental test ends, thereby improving the accuracy and efficiency of the test.

[0014] Preferably, the push block includes a moving part and a connecting part, the connecting part being detachably fixed to the moving part by a locking member, and a clearance hole for the power supply line to pass through is formed at the connection between the moving part and the connecting part.

[0015] By adopting the above technical solution, a moving part and a connecting part are set in the push block. The connecting part is detachably fixed to the moving part by a locking member, and there is a clearance hole for the power supply line to pass through at the connection point. By setting the locking member, the operator can tighten the moving part and the connecting part when they are in a loose state, which reduces the risk of the wire slipping or falling out of the clearance hole during the experimental test. The clearance hole allows the wire to have a bending area. When the wire touches the side wall of the clearance hole, the wire will bend, ensuring that the wire bends whenever the push block moves to the proximity sensor, thereby improving the accuracy of the experimental test results.

[0016] Preferably, the housing is provided with a speed adjustment knob, which is connected in series with the motor via a terminal block.

[0017] By adopting the above technical solution, the speed control knob is connected in series with the motor through the terminal block. The operator can adjust the motor's drive speed according to the thickness of the wire by using the speed control knob, thereby improving the accuracy of the wire bending test.

[0018] Preferably, the housing is provided with an indicator light, which is connected in series with the motor, and the indicator light is used to observe the working status of the device.

[0019] By adopting the above technical solution, the indicator light is connected in series with the motor. During operation, the operator can directly judge whether there is a circuit break or wire damage in the experimental testing device by observing whether the indicator light is on or off, which improves the flexibility of operating the device.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] The wire passes through the push block and is then fixed to the terminal clamp. The positive and negative terminals of the wire are connected to two terminals. The terminal clamp keeps the wire in a fixed position, ensuring a stable connection. The wire between the push block and the terminal clamp can bend freely. The drive component is powered on after being connected to the terminal clamp. When powered on, the drive component drives the push block to move back and forth towards or away from the terminal clamp to bend the wire. Each reciprocation triggers a proximity sensor to send a signal to a counter to count the bends until the wire breaks, causing the drive component to be de-energized. This completes the test of the number of wire bends, thereby improving the accuracy and efficiency of the test.

[0022] After power is applied, the motor drives the linkage to start moving. The push rod connected to the linkage moves back and forth along the direction of the proximity sensor under the guide rail of the guide block. When the push block on the push rod approaches the proximity sensor, the proximity sensor recognizes it and sends a signal to the counter to start counting until the wire breaks, the drive component is powered off, and the test ends, thereby improving the accuracy and efficiency of the test.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a device for testing the bending resistance of electrical wires. (Refer to...) Figure 1 and Figure 2The wire bending resistance test apparatus includes a rectangular housing 1, a connector 2, two terminals 3, a counter 4, a repetitive bending drive mechanism 5, and a power switch 12. The two terminals 3 are located on the surface of the housing 11 and are used to connect the positive and negative terminals of the wire. The power switch 12 controls the connection and disconnection of mains power. The connector 2 is used to detachably fix the wire portion connected to the terminals 3. The repetitive bending drive mechanism 5 includes a push block 51 and a drive assembly 52 that drives the push block 51 to move back and forth towards or away from the connector 2. The push block 51 connects to and pushes the wire. The drive assembly 52 is connected to the power supply via the two terminals 3, allowing the drive assembly 52 to drive the push block 51 to move back and forth. A proximity sensor 6 is located near the connector 2 on the housing 1. The push block 51 is made of metal. As the push block 51 approaches the connector 2, it triggers the proximity sensor 6 to send a trigger signal to the counter 4, causing the counter 4 to count. The wire passes through the push block 51 and is then fixed to the terminal clamp 2. The positive and negative terminals at both ends of the wire are connected to two terminals 3. The terminal clamp 2 keeps the wire between the wire and the terminal 3 in a fixed and immovable state, thus ensuring a stable connection between the wire and the terminal 3. The wire between the push block 51 and the terminal clamp 2 can bend freely. The drive component 52 is connected to the terminal 3 and then powered on. After being powered on, the drive component 52 drives the push block 51 to move back and forth towards or away from the terminal clamp 2 to bend the wire. Each reciprocation triggers the proximity sensor 6 to send a signal to the counter 4 to count until the wire breaks, causing the drive component 52 to be de-energized. This completes the test of the number of wire bends, thereby improving the accuracy and efficiency of the test.

[0029] Reference Figure 2 Furthermore, the wiring clamp 2 includes a fixed base 21, a locking member 22, and a clamping block 23. The fixed base 21 is fixed to the housing 1; the clamping block 23 is located on the upper surface of the fixed base 21; the locking member 22 is rotatably connected to the clamping block 23 and simultaneously threadedly connected to the fixed base 21. In this embodiment, the locking member 22 is a wing screw. By fixing the mounting base 21 to the housing 1, a stable connection between the bottom of the connector 2 and the housing 1 is ensured, preventing the connector 2 from sliding during operation. The clamping block 23 is set on the upper surface of the mounting base 21, and the locking member 22 is rotatably connected to the clamping block 23 and simultaneously threadedly connected to the mounting base 21, which improves the connection stability between the clamping block 23 and the mounting base 21 and reduces the risk of the wire slipping or falling off during testing. The locking member 22 is set as a wing screw, which allows the operator to easily insert the wire by manually turning the wing screw before the wire bending experiment or when the clamping block 23 is open. Furthermore, if the clamping block 23 and the mounting base 21 become loose, the tightness of the clamping block 23 and the mounting base 21 can be adjusted by manually turning the wing screw, so that the clamping block 23 and the mounting base 21 are fixedly connected.

[0030] Reference Figure 2Furthermore, the upper surface of the mounting base 21 has two receiving slots 9 for placing wires. Inserting the wires into the receiving slots 9 can reduce the risk of the wires being damaged by pressure due to the fixed connection between the clamp 23 and the mounting base 21.

[0031] Reference Figure 2 and Figure 3 Furthermore, the drive assembly 52 includes a motor 521, a connecting rod 522, a push rod 523, and a guide block 524. The motor 521 is connected to a power source via wires and terminals 3. The output shaft of the motor 521 is connected to one end of the connecting rod 522. The other end of the connecting rod 522 is connected to the push rod 523. The end of the push rod 523 is fixedly connected to the push block 51. The guide block 524 is fixed on the housing 1. The push rod 523 is movably inserted through the guide block 524. The motor 521 drives the connecting rod 522 to drive the push rod 523 to move the push block 51 back and forth in a straight line through the guide block 524. After power is applied, the motor 521 drives the connecting rod 522 to start moving. The push rod 523 connected to the connecting rod 522 moves back and forth along the direction of approaching the terminal clamp 2 under the guidance of the guide block 524. After the push block 51 on the push rod 523 approaches the terminal clamp 2, the proximity sensor 6 recognizes it and sends a signal to the counter 4 to start counting until the wire breaks, the drive assembly 52 is de-energized, and the test ends, thereby improving the accuracy and efficiency of the test.

[0032] Reference Figure 2 To reduce the occurrence of wires slipping or detaching from the push block 51 during experimental testing, the push block 51 further includes a moving part 511 and a connecting part 512. The connecting part 512 is detachably fixed to the moving part 511 by a fixing member 10. A clearance hole 11 for the power supply wire to pass through is formed at the connection between the moving part 511 and the connecting part 512. In this embodiment, the fixing member 10 is a wing screw. A moving part 511 and a connecting part 512 are provided in the push block 51. The connecting part 512 is detachably fixed to the moving part 511 by a fixing member 10, and a clearance hole 11 for the power supply wire to pass through is provided at the connection point. By providing the fixing member 10, the operator can tighten the moving part 511 and the connecting part 512 when they are in a loose state, thereby reducing the risk of the wire slipping or falling out of the clearance hole 11 during the experimental test. The clearance hole 11 provides a bending area for the wire. When the wire touches the side wall of the clearance hole 11, the wire will bend, ensuring that the wire bends whenever the push block 51 moves to the proximity sensor 6, thereby improving the accuracy of the experimental test results. Before the experiment, the operator can separate the connecting part 512 from the moving part 511 by twisting the wing screw, connect the wire to be tested into the clearance hole 11, and then twist the wing screw to fix the connecting part 512 to the moving part 511, thereby reducing the risk of the wire slipping or falling out during the bending process.

[0033] Reference Figure 2 and Figure 3 Furthermore, the housing 1 is equipped with a speed adjustment knob 7, which is connected in series with the motor 521 via a terminal 3. Because the speed adjustment knob 7 is connected in series with the motor 521 via the terminal 3, the operator can adjust the drive speed of the motor 521 according to the thickness of the wire, thereby improving the accuracy of the wire bending test.

[0034] Reference Figure 1 and Figure 3 Furthermore, the housing 1 is equipped with an indicator light 8, which is connected in series with the motor 521. The indicator light 8 is used to observe the working status of the device. When the wire bending resistance test device is in working condition, the indicator light 8 remains yellow. If the circuit of the device is open or the wire is broken, the indicator light 8 will turn off and not light up. By setting the indicator light 8 to observe the working status of the wire bending resistance test device, the operator can directly judge whether the circuit of the device is open or whether there is wire damage by observing whether the indicator light 8 is on or off, thus improving the flexibility of operating the device.

[0035] Reference Figure 3 Furthermore, the power supply is connected to the switching power supply 13, which is used to convert the mains power into 24V DC power to power the motor. The switching power supply 13 is connected in series with the counter 4 and the proximity sensor 6 to ensure that when the push block 51 approaches the proximity sensor 6, the proximity sensor 6 can send a signal to the counter 4, so that the counter 4 starts counting.

[0036] The principle of the wire bending resistance test device in this application embodiment is as follows: the wire passes through the push block 51 and is then fixed on the terminal clamp 2, and the positive and negative terminals at both ends of the wire are connected to two terminals 3. The terminal clamp 2 keeps the wire between the wire and the terminal 3 in a fixed and immovable state, thereby stabilizing the connection between the wire and the terminal 3. The wire between the push block 51 and the terminal clamp 2 can be bent flexibly. The drive component 52 is connected to the terminal 3 and then energized. After being energized, the drive component 52 drives the push block 51 to move back and forth towards or away from the terminal clamp 2 to bend the wire. Each reciprocation triggers the proximity sensor 6 to send a signal to the counter 4 to count, until the wire breaks, causing the drive component 52 to be de-energized, thereby completing the test of the number of wire bends, thus improving the accuracy and efficiency of the test.
