[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and can close, carry, and interrupt current under abnormal circuit conditions within a specified time.

[0003] A search revealed a wire breakage detection device (202222641525.6), comprising a base and a wire reel. A side plate is fixedly mounted on the top of the base, and a motor is fixedly mounted on the rear side of the side plate. The output end of the motor is fixedly connected to a rotating seat extending to the front of the side plate. A gear is rotatably connected inside the rotating seat. A first knob extending to the front of the rotating seat is fixedly connected to the front of the gear. A first rack meshes with the left side of the gear. A first sliding plate is fixedly connected to the top of the first rack, and a first locking rod extending to the top of the rotating seat is fixedly connected to the top of the first sliding plate.

Several limiting gears are rotatably connected to the outer side of the limiting disc. The teeth of the annular rack seat are located on the inner surface of the annular rack seat and mesh with the limiting gears. The fastening assembly also includes several variable diameter clamping blocks, each fixedly connected to the limiting gear. Limiting grooves are formed on the outer side of each variable diameter clamping block. The head of each variable diameter clamping block is slidably connected to the limiting groove of the adjacent variable diameter clamping block. Several variable diameter clamping blocks are connected end to end in sequence to form a closed loop structure.

[0010] The adjusting part includes an electric telescopic rod vertically mounted on the sliding assembly. The output end of the electric telescopic rod is fixedly connected to a push rod, which is fixedly connected to the protruding end.

[0011] The detection assembly includes a detection plate vertically mounted on the top of the test bench and a circuit breaking characteristic tester. The circuit breaking characteristic tester is located on one side of the detection plate, and the sliding assembly is located on the other side of the detection plate. The detection plate is provided with detection contacts, and the circuit breaking characteristic tester is electrically connected to the detection contacts. The detection contacts correspond to the clamping assembly.

[0012] The sliding assembly includes a sliding seat mounted on the top of the test bench, a sliding frame slidably connected to the top of the sliding seat, a wheel fork at the bottom of the sliding frame, a servo motor mounted on the side wall of the wheel fork, a transmission gear rotatably connected to the middle section of the wheel fork, and the motor shaft of the servo motor passing through the side wall of the wheel fork and fixedly connected to the middle of the transmission gear via a coupling; an embedded rack with meshing with the external teeth of the transmission gear is provided on the inner side of the sliding seat; the positioning sleeve and the electric telescopic rod are both mounted on the sliding frame.

[0013] The winding assembly includes a winding section disposed on a sliding frame, the winding section being disposed on the side away from the detection assembly, the winding section including a stepper motor, a drive shaft and an I-beam winding drum, the motor shaft of the stepper motor being fixedly connected to one end of the drive shaft via a coupling, and the outer wall of the drive shaft being tightly fitted to the inner wall of the I-beam winding drum.

[0014] The test bench is also equipped with a limiting platform on its top, which is located at the end of the sliding frame away from the detection component.

[0015] The sliding assembly is provided in four sets, each set of sliding assembly includes two sliding seats, the bottom of the sliding frame is slidably connected to the two sliding seats, the winding assembly and the clamping assembly are both provided in four sets, the detection contacts are provided in four sets, the four detection contacts correspond to the four sets of clamping assemblies respectively, and the circuit breaking characteristic tester is electrically connected to the four detection contacts.

[0016] A method for using a conductor circuit breaker detector includes the following steps:

[0017] S1: The wire is introduced into the closed loop structure formed by connecting the ends of the variable diameter clamping block. Then, the electric telescopic rod is activated to drive the variable diameter clamping block on the outside to rotate, so as to flexibly change the insertion diameter of the wire and securely clamp the wire.

[0018] S2: Start the servo motor to make the conductive pin of the metal wire connected to the detection contact of the circuit characteristic tester;

[0019] S3: The conductor is qualified when the detection signal of the circuit breaker can be received normally.

[0020] S4: If the circuit breaker tester cannot receive the detection signal normally, the wire is unqualified;

[0021] S5: Start the stepper motor to complete the winding of the wire and classify and store the qualified and unqualified wires.

[0022] The present invention has the following beneficial effects:

[0023] This device, through gear transmission between the gear teeth of the ring rack seat and the limiting gear, allows the limiting gear, rotatably connected to the outside of the limiting disc, to rotate in the same direction. The limiting gear drives the variable diameter clamping block to rotate, changing the size between the variable diameter clamping blocks to accommodate wires of different diameters. Under the combined action of the variable diameter clamping blocks, the insertion diameter of the wire can be flexibly changed, thus achieving a secure clamping of the wire. Driven by a servo motor, the variable diameter clamping block can pull the conductive pin of the metal wire to connect with the detection contact of the circuit breaker tester, thereby ensuring an effective short circuit of the wire. When the detection signal of the circuit breaker tester can be received normally, the wire with that pin is considered to be conductive and qualified. By setting multiple sets of clamping components, multi-wire testing operations can be completed, thereby improving work efficiency.

[0024] This device, through the meshing connection between the external teeth of the transmission gear and the embedded rack, allows the sliding frame to extend outward in the horizontal direction along the outer wall of the sliding seat, thereby achieving a sliding effect. After the test is completed, the stepper motor drives the transmission shaft to rotate, and the transmission shaft drives the I-beam winding drum to rotate at the top of the sliding frame, thereby completing the rapid winding effect of the wire and facilitating its storage.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0033] Please see Figures 1 to 5 The invention provides a technical solution:

[0034] A wire breakage detector includes a test bench 11, a detection component and a sliding component disposed on the test bench 11, and a winding component and a clamping component disposed on the sliding component. The clamping component is used to clamp the wire and includes a clamping part 2 and an adjusting part. The adjusting part is used to adjust the diameter of the clamping part 2 to accommodate wires of different diameters. The sliding component allows the winding component and the clamping component to slide on the test bench 11, so that after the clamping component clamps the wire, it can slide to touch the detection component to perform breakage detection. After the detection is completed, they separate, and the winding component then winds up the detected wire.

[0035] The testing assembly includes a testing plate vertically mounted on the top of the test bench 11 and a circuit breaking characteristic tester 12. The testing plate separates the test bench 11 into two sides. The circuit breaking characteristic tester 12 is located on one side of the testing plate, and a sliding component is located on the other side of the testing plate. The testing plate is provided with a number of testing contacts 8. The circuit breaking characteristic tester 12 is electrically connected to the number of testing contacts 8, and the number of testing contacts 8 corresponds to a number of clamping components.

[0036] The sliding assembly includes a sliding seat 13 mounted on the top of the test bench 11. The sliding seat 13 is vertically mounted to the test plate. Each sliding assembly includes two sliding seats 13. A sliding frame 14 is slidably connected to the top of the two sliding seats 13. Two wheel forks are mounted on the bottom of the sliding frame 14, each corresponding to one of the two sliding seats 13. A servo motor 5 is mounted on the side wall of the wheel fork. A transmission gear 6 is rotatably connected to the middle section of the wheel fork. The motor shaft of the servo motor 5 passes through the side wall of the wheel fork and is fixedly connected to the middle of the transmission gear 6 through a coupling. When the servo motor 5 is started... This drives the transmission gear 6 to rotate. The inner side of the sliding seat 13 is provided with an embedded rack 7 that meshes with the outer teeth of the transmission gear 6. During the movement, the running servo motor 5 drives the transmission gear 6 to rotate. Under the meshing transmission of the outer teeth of the transmission gear 6 and the embedded rack 7, the sliding frame 14 can extend outward in the horizontal direction along the outer wall of the sliding seat 13, thereby achieving the transmission effect. The winding assembly and the clamping assembly are both set on the sliding frame 14. The winding assembly is set at the end away from the detection plate, and the clamping assembly is set at the end closer to the detection plate.

[0037] The clamping part 2 includes two positioning sleeves 21 disposed on the sliding assembly, with a gap between the two positioning sleeves 21. An annular rack seat 22 is rotatably disposed between the two positioning sleeves 21. The two ends of the outer wall surface of the annular rack seat 22 are rotatably connected to the two positioning sleeves 21, and the middle end of the outer wall surface of the annular rack seat 22 is exposed in the gap. A protruding end is provided at the middle end of the outer wall surface of the annular rack seat 22. The adjusting part includes an electric telescopic rod 3 vertically disposed on the sliding assembly. The output end of the electric telescopic rod 3 is fixedly connected to the bottom of the push rod 4, and the top of the push rod 4 is fixedly connected to the protruding end of the annular rack seat 22. A fastening assembly is disposed inside the annular rack seat 22. By activating the electric telescopic rod 3 at the top of the sliding frame 14, its output end pushes the push rod 4, and the push rod 4 drives the annular rack seat 22 to rotate along one side of the limiting plate 23, thereby completing the adjustment of the fastening assembly to accommodate wires of different sizes.

[0038] The fastening assembly includes a limiting disc 23, with several limiting gears 24 rotatably connected to the outer side of the limiting disc 23. The limiting disc 23 is rotatably connected to the inner side of an annular rack seat 22, and the teeth of the annular rack seat 22 are located on the inner surface of the annular rack seat 22. The teeth of the annular rack seat 22 mesh with the limiting gears 24, forming a structure similar to a meteor gear. The fastening assembly also includes several variable diameter clamping blocks 25, with limiting grooves 9 formed on the outer side of each variable diameter clamping block 25. The head of each variable diameter clamping block 25 is slidably connected to the limiting grooves 9 of adjacent variable diameter clamping blocks 25. Several variable diameter clamping blocks 25 are connected end to end to form a closed loop structure, and each variable diameter clamping block 25 is fixedly connected to the limiting gears 24. The surface of the variable diameter clamping block 25 is fixedly connected to the outer wall of the limiting gear 24. Since the internal teeth of the ring rack seat 22 mesh with the limiting gear 24, the limiting gear 24, which is rotatably connected to the outside of the limiting disk 23, can rotate in the same direction under the gear transmission. The limiting gear 24 drives the variable diameter clamping block 25 on its outer side to rotate on the adjacent limiting groove 9. Under the joint action of multiple sets of variable diameter clamping blocks 25, the insertion diameter of the anti-conductor can be flexibly changed, thereby completing the reliable clamping of the conductor. That is, when several variable diameter clamping blocks 25 are in the maximum position, their outer tips can be embedded in the limiting groove 9 of another variable diameter clamping block 25, thereby ensuring the stability after the diameter change.

[0039] The winding assembly includes a winding section 15 mounted on the sliding frame 14. The winding section 15 is located on the side away from the detection assembly. The winding section 15 includes a stepper motor 151, a drive shaft 152, and a bevel winding drum 153. The motor shaft of the stepper motor 151 is fixedly connected to one end of the drive shaft 152 via a coupling. The outer wall of the drive shaft 152 is tightly fitted to the inner wall of the bevel winding drum 153. After the test is completed, the stepper motor 151 drives the drive shaft 152 to rotate. The drive shaft 152 drives the bevel winding drum 153 to rotate at the top of the sliding frame 14, thereby achieving a rapid winding effect for the wire and facilitating its storage.

[0040] As a preferred embodiment, a limiting platform is also provided on the top of the test stand 11, which is located at the end of the sliding frame 14 away from the detection component; in order to prevent the sliding frame 14 from slipping off the sliding seat 13 during the sliding process.

[0041] A method for using a conductor circuit breaker detector includes the following steps:

[0042] S1: The wire is introduced into the variable diameter clamping block 25 and connected end to end to form a closed loop structure. Then, the electric telescopic rod 3 is activated to drive the variable diameter clamping block 25 on its outer side to rotate, so as to flexibly change the insertion diameter of the wire and securely clamp the wire.

[0043] S2: Start the servo motor 5 to make the conducting pin of the metal wire connected to the detection contact 8 of the circuit breaking characteristic tester 12;

[0044] S3: When the detection signal of the circuit breaker characteristic tester 12 can be received normally, the wire is qualified;

[0045] S4: If the detection signal of the circuit breaker characteristic tester 12 cannot be received normally, the wire is unqualified;

[0046] S5: Start stepper motor 151 to complete the winding of the wire and classify and store qualified and unqualified wires.

[0047] The working principle of the above-mentioned wire break detector is as follows:

[0048] The electric telescopic rod 3 at the top of the electrically started sliding frame 14 pushes the push rod 4 at its output end. The push rod 4 drives the ring rack seat 22 to rotate along one side of the limiting plate 23. Since the internal teeth of the ring rack seat 22 mesh with the limiting gear 24, the limiting gear 24, which is rotatably connected to the outside of the limiting plate 23, can rotate in the same direction under the gear transmission. The limiting gear 24 drives the variable diameter clamping block 25 on its outside to rotate. Under the combined action of multiple sets of variable diameter clamping blocks 25, the insertion diameter of the anti-wire is flexibly changed, thereby completing the secure clamping of the wire. Driven by the servo motor 5, the variable diameter clamping block 25 can pull the conductive pin of the metal wire to conduct with the detection contact 8 of the circuit breaking characteristic tester 12, thereby ensuring the effective short circuit of the wire. When the detection signal of the circuit breaking characteristic tester 12 can be received normally, the wire is qualified for conduction. The multi-wire detection operation of the wire is completed through multiple sets of clamping components, thereby improving the efficiency.

[0049] During the movement, the running servo motor 5 drives the transmission gear 6 to rotate. Under the meshing transmission of the external teeth of the transmission gear 6 and the embedded rack 7, the sliding frame 14 can extend outward in the horizontal direction along the wall of the sliding seat 13, thereby achieving the transmission effect. After the test is completed, the stepper motor 151 drives the transmission shaft 152 to rotate. The transmission shaft 152 drives the I-beam reel winding drum 153 to rotate at the top of the sliding frame 14, thereby completing the rapid winding effect of the wire and facilitating its storage.
