Description

Technical Field

[0001] This application relates to the field of cable production equipment, and in particular to a self-testing stranded wire device. Background Technology

[0002] Twisted pair cable is the most commonly used transmission medium in structured cabling projects. It consists of two copper wires with insulating protective layers. The two insulated copper wires are twisted together at a certain density. The electromagnetic waves radiated by each wire during transmission are canceled out by the electromagnetic waves emitted by the other wire, effectively reducing the degree of signal interference.

[0003] Currently, stranding equipment is commonly used to replace manual winding of stranded wires, which greatly improves production efficiency. However, existing stranding equipment does not have the ability to inspect the quality of the finished product after stranding. For some thinner cables, the tension may be too high during the stranding process, which may damage the wire core inside the cable. Therefore, it is necessary to use other equipment to inspect the stranded wire in the subsequent process, which increases the number of processes and incurs more equipment costs.

[0004] Therefore, there is a need for a self-testing stranded wire device. Summary of the Invention

[0005] To address the issue of the inability to automatically detect stranded wires in a timely manner, this application provides a self-testing stranded wire device.

[0006] The self-testing twisted wire device provided in this application adopts the following technical solution: A self-testing twisted wire device includes a slide rail, a rotating assembly, and a moving assembly; the slide rail includes a pair of tracks arranged opposite each other; the rotating assembly is located at one end of the tracks and includes a rotating jaw unit adapted to clamp the twisted wire and a jaw drive unit, the jaw drive unit being connected to the rotating jaw unit to drive the rotating jaw unit to rotate; the moving assembly includes a moving base, a fixed jaw, and a pushing unit, the fixed jaw being adapted to clamp the twisted wire and located on the moving base, the moving base being located on the tracks and connected to the pushing unit. The unit is connected to the rotating gripper unit so that it can move along the track under the drive of the pushing unit; the rotating gripper unit is provided with a moving gripper electrode plate, the fixed gripper is provided with a fixed gripper electrode plate and an indicator, one end of the twisted pair can abut against the moving gripper electrode plate, and the other end can abut against the fixed gripper electrode plate. The fixed gripper electrode plate is connected to the indicator and also connected to the power supply. The current released by the power supply can sequentially pass through the fixed gripper electrode plate, the indicator, one of the twisted pairs, the moving gripper electrode plate, the other of the twisted pairs, and the fixed gripper electrode plate before flowing into the power supply.

[0007] By adopting the above technical solution, the two ends of the twisted pair can be clamped by the rotating jaw unit and the fixed jaw respectively. After clamping, the rotating jaw unit will drive the twisted pair to rotate under the drive of the jaw drive unit to perform the twisting operation. The moving seat can move on the track, thereby adjusting the distance between the moving seat and the rotating component to adapt to the twisting operation of cables of different sizes. In addition, the fixed jaw electrode plate, the indicator, the twisted pair, the moving jaw electrode plate and the fixed jaw electrode plate can form a series circuit. After the rotating jaw unit stops rotating and completes the twisting operation, this series circuit can be connected to the power supply, and the quality problem of whether the produced twisted pair has damaged cores can be checked in time by whether the indicator emits an indication signal.

[0008] Furthermore, the slide rail also includes a collection groove disposed between the tracks and located at the lower part of the tracks; the pushing unit is disposed on the track at one end away from the rotating component, and the self-testable stranded wire device also includes a controller, the pushing unit is connected to the movable seat, and the pushing unit is also electrically connected to the controller, and the controller is also electrically connected to the gripper drive unit, so that when the gripper drive unit drives the rotating gripper unit to rotate, the controller controls the pushing unit to push the movable seat toward the rotating component.

[0009] By adopting the above technical solution, after the rotating gripper unit and the fixed gripper open, the twisted pair cable that has completed the twisting operation will fall into the collection trough for easy collection of the finished twisted pair cable; while the rotating gripper unit drives the twisted pair cable to rotate, the pushing unit will push the moving seat close to the rotating component so that the cable will not be too taut during the twisting process, which would cause the twisted pair cable to be damaged.

[0010] Furthermore, the rotating gripper unit also includes a moving gripper housing, a moving gripper body, and a moving gripper adjusting bolt; the moving gripper housing has a moving gripper cable receiving groove, a moving gripper cable passing hole communicating with the moving gripper cable receiving groove, and a moving gripper screw hole; the moving gripper electrode plate includes a moving electrode plate crimping section and a moving electrode plate abutting section adapted to abut against the end of the twisted pair and capable of conducting electricity, the moving electrode plate abutting section is disposed in the moving gripper cable receiving groove, and can move closer to or further away from the moving gripper cable passing hole along the moving gripper cable receiving groove, the moving electrode plate crimping section has a moving electrode plate adjusting groove, and the moving gripper adjusting bolt can pass through the moving electrode plate adjusting groove and be screwed into the moving gripper screw hole; the clamping end of the moving gripper body is disposed at the moving gripper cable passing hole, so that when the twisted pair passes through the moving gripper cable passing hole and abuts against the moving gripper electrode plate, the moving gripper body clamps the twisted pair.

[0011] By adopting the above technical solution, the moving claw cable receiving groove can be used to accommodate the plug-in device set at the end of the twisted pair cable, and the setting of the moving electrode plate adjustment groove can realize the movement and adjustment of the moving electrode plate abutting section in the moving claw cable receiving groove, so as to adjust the distance between the moving electrode plate abutting section and the moving claw cable through hole according to the size of the plug-in device set at the end of the twisted pair cable. In this way, while ensuring that the plug-in device can abut with the moving electrode plate abutting section to achieve conductivity, it also ensures that the end of the twisted pair cable placed in the moving claw cable receiving groove is not prone to large bending, so that the twisted pair cable is not easily bent and damaged.

[0012] Furthermore, the movable gripper body includes a pair of movable gripper holding rods and a pair of movable gripper driving links. The movable gripper housing is also provided with a pair of movable gripper hinge seats. Each side of the movable gripper cable receiving groove is provided with a movable gripper hinge seat. One end of the movable gripper holding rod is a gripping end. The middle part of the movable gripper holding rod is hinged to the movable gripper hinge seat, and the other end of the movable gripper holding rod is hinged to one end of the movable gripper driving link. The other end of the movable gripper driving link is provided with a movable gripper connecting post. The movable gripper connecting post is connected to the gripper driving unit. The movable gripper connecting post can move closer to or further away from the movable gripper cable through hole under the drive of the gripper driving unit to adjust the distance between the gripping ends on the two movable gripper holding rods.

[0013] By adopting the above technical solution, when the moving claw connecting post moves toward the direction of the moving claw cable through hole, the distance between the clamping ends on the two moving claw clamping rods will decrease to enable clamping of the twisted pair cable. When the moving claw connecting post moves away from the moving claw cable through hole, the distance between the clamping ends on the two moving claw clamping rods will increase to enable opening and removal of the twisted pair cable.

[0014] Furthermore, the gripper drive unit includes a rotary motor, a rotary shaft, a push rod, and a moving gripper push cylinder. The rotary shaft is connected to the moving gripper housing and is also drively connected to the rotary motor. The rotary shaft is hollow, and the push rod passes through the rotary shaft. One end of the push rod is connected to the moving gripper connecting post, and the other end of the push rod is connected to the moving gripper push cylinder, so that the push rod can be driven by the moving gripper push cylinder to move closer to or away from the moving gripper cable through hole. The telescopic rod of the moving gripper push cylinder is provided with a connecting sleeve, and the push rod and the connecting sleeve are rotatably connected.

[0015] By adopting the above technical solution, it is possible to control the opening and clamping states of the moving gripper body.

[0016] Furthermore, a moving claw sensor is provided at the through hole of the moving claw cable. The moving claw sensor is adapted to detect whether the twisted pair cable is threaded through the through hole of the moving claw cable. The moving claw sensor is electrically connected to the controller so that when the moving claw sensor detects that the twisted pair cable is threaded through the through hole of the moving claw cable, the controller controls the moving claw push cylinder to drive the push rod to reduce the distance between the clamping ends on the two moving claw clamping rods.

[0017] By adopting the above technical solution, the twisted pair cable can be automatically clamped when the moving gripper detects that the cable has passed through the hole.

[0018] Furthermore, the fixed clamp further includes a fixed clamp housing, a fixed clamp body, and a fixed clamp adjusting bolt; the fixed clamp housing has a fixed clamp cable receiving groove, a fixed clamp cable passing hole communicating with the fixed clamp cable receiving groove, and a fixed clamp screw hole; the fixed clamp electrode plate includes a fixed electrode plate crimping section and a fixed electrode plate abutting section adapted to abut the end of the twisted pair and capable of conducting electricity, the fixed electrode plate abutting section is disposed in the fixed clamp cable receiving groove and can move closer to or further away from the fixed clamp cable passing hole along the fixed clamp cable receiving groove, a fixed electrode plate adjusting groove is formed on the fixed electrode plate crimping section, and the fixed clamp adjusting bolt can pass through the fixed electrode plate adjusting groove and be screwed into the fixed clamp screw hole; the clamping end of the fixed clamp body is disposed at the fixed clamp cable passing hole, so that when the twisted pair passes through the fixed clamp cable passing hole and abuts the fixed clamp electrode plate, the fixed clamp body clamps the twisted pair.

[0019] By adopting the above technical solution, the fixed clamp cable receiving groove can be used to accommodate the plug-in device set at the end of the twisted pair cable, and the setting of the fixed plate adjustment groove can realize the movement and adjustment of the fixed plate abutment section in the fixed clamp cable receiving groove, so as to adjust the distance between the fixed plate abutment section and the fixed clamp cable through hole according to the size of the plug-in device set at the end of the twisted pair cable. In this way, while ensuring that the plug-in device can abut with the fixed plate abutment section to achieve conductivity, it also ensures that the end of the twisted pair cable placed in the fixed clamp cable receiving groove is not prone to large bending, so that the twisted pair cable is not easily bent and damaged.

[0020] Furthermore, two insertion holes are formed on the contact section of the fixed electrode plate, and electrode plates are provided on the groove surface of the insertion holes. Both electrode plates are electrically connected to the power supply, and the indicator is connected in series between the power supply and one of the electrode plates.

[0021] By adopting the above technical solution, the two cables in the twisted pair can be connected to the electrode plates in the corresponding plug holes respectively, so as to ensure that the current can flow through the two cables in sequence to achieve effective detection, and the detection result can be reflected by the indicator.

[0022] Furthermore, the fixed gripper body includes a pair of fixed gripper holding rods and a pair of fixed gripper driving linkages, and the fixed gripper also includes a fixed gripper pushing cylinder. The fixed gripper housing is also provided with a pair of fixed gripper hinge seats. Each side of the fixed gripper cable receiving groove is provided with a fixed gripper hinge seat. One end of the fixed gripper holding rod is a gripping end. The middle part of the fixed gripper holding rod is hinged to the fixed gripper hinge seat, and the other end of the fixed gripper holding rod is hinged to one end of the fixed gripper driving linkage. The other end of the fixed gripper driving linkage is provided with a fixed gripper connecting post. The fixed gripper connecting post is connected to the fixed gripper pushing cylinder so that it can move closer to or further away from the fixed gripper cable through hole under the drive of the fixed gripper pushing cylinder, so as to adjust the distance between the gripping ends on the two fixed gripper holding rods.

[0023] By adopting the above technical solution, when the fixed claw connecting post moves toward the direction of the fixed claw cable through hole, the distance between the clamping ends on the two fixed claw clamping rods will decrease to enable clamping of the twisted pair cable. When the fixed claw connecting post moves away from the fixed claw cable through hole, the distance between the clamping ends on the two fixed claw clamping rods will increase to enable opening and removal of the twisted pair cable.

[0024] Furthermore, a fixed claw sensor is provided at the fixed claw cable through hole, the fixed claw sensor being adapted to detect whether the twisted pair cable is threaded through the fixed claw cable through hole; the fixed claw sensor is electrically connected to the controller, so that when the fixed claw sensor detects that the twisted pair cable is threaded through the fixed claw cable through hole, the controller controls the fixed claw push cylinder to drive the fixed claw connecting column to reduce the distance between the clamping ends on the two fixed claw clamping rods.

[0025] By adopting the above technical solution, the twisted pair can be automatically clamped when the cable through the fixed clamping claw is detected.

[0026] In summary, this application includes at least one of the following beneficial effects: The two ends of the twisted pair are held by a rotating jaw unit and a fixed jaw, respectively. After clamping, the rotating jaw unit drives the twisted pair to rotate under the drive of the jaw drive unit to perform the twisting operation. The movable seat can move on the track, thereby adjusting the distance between the movable seat and the rotating component to accommodate the twisting operation of cables of different sizes. In addition, the fixed jaw electrode plate, the indicator, the twisted pair, the movable jaw electrode plate, and the fixed jaw electrode plate can form a series circuit. After the rotating jaw unit stops rotating and completes the twisting operation, this series circuit can be connected to the power supply, and the quality problem of whether the produced twisted pair has damaged cores can be checked in time by whether the indicator emits an indication signal.

Detailed Implementation

[0029] Figure 1 This is a perspective view of a self-testing twisted wire device according to this application. Figure 2 This is a top view of a self-testing twisted wire device according to this application. See also... Figure 1 and Figure 2 The self-testable stranded wire device provided in this application includes a slide rail 1, a rotating component 2 and a moving component 3, wherein the slide rail 1 includes a pair of tracks 11 arranged opposite to each other.

[0030] Figure 3 yes Figure 2 Cross-sectional view along the AA direction, see Figure 2 and Figure 3 The rotating assembly 2 is located at one end of the track 11 and can be specifically configured to include a rotating jaw unit 21 adapted to clamp the twisted pair cable and a jaw drive unit 22. The jaw drive unit 22 is connected to the rotating jaw unit 21 to drive the rotating jaw unit 21 to rotate. The moving assembly 3 can be configured to include a moving base 31, a fixed jaw 32, and a pushing unit 33. The fixed jaw 32 is adapted to clamp the twisted pair cable and is located on the moving base 31. The moving base 31 is located on the track 11 and is connected to the pushing unit 33 so that it can move along the track 11 under the drive of the pushing unit 33, thereby clamping both ends of the twisted pair cable through the rotating jaw unit 21 and the fixed jaw 32. After clamping, the rotating gripper unit 21 will drive the twisted pair to rotate under the drive of the gripper drive unit 22 to perform the twisting operation. The movable seat 31 can move on the track 11, thereby adjusting the distance between the movable seat 31 and the rotating component 2 to accommodate the twisting operation of cables of different sizes. It is understood that multiple rotating gripper units 21 can be set, and the number of fixed grippers 32 needs to be consistent with the number of rotating gripper units 21, so that the rotating gripper units 21 and the fixed grippers 32 can correspond one-to-one, thereby enabling the simultaneous twisting operation of multiple twisted pairs to be twisted, thereby improving production efficiency.

[0031] Figure 4 yes Figure 2 Enlarged view of region B in the middle. Figure 5 yes Figure 2 See the enlarged view of region C in the middle. Figure 3 and Figure 4The rotating gripper unit 21 is equipped with a movable gripper electrode plate 211, and the fixed gripper 32 is equipped with a fixed gripper electrode plate 32 and an indicator 322. One end of the twisted pair cable can abut against the movable gripper electrode plate 211, and the other end can abut against the fixed gripper electrode plate 32. The fixed gripper electrode plate 32 is connected to the indicator 322 and also to the power supply, so that the fixed gripper electrode plate 32, the indicator 322, the twisted pair cable, the movable gripper electrode plate 211, and the fixed gripper electrode plate 32 form a series circuit. Therefore, when the rotating gripper unit 21 stops rotating and completes the twisting operation, the power supply will connect to the fixed gripper electrode plate 32. When the electrode plates are connected, the current released by the power supply can sequentially pass through the fixed clamp 32 electrode plate, the indicator 322, one of the twisted pairs, the moving clamp electrode plate 211, the other twisted pair, and the fixed clamp 32 electrode plate before flowing into the power supply. The indicator 322 can be a light-emitting device such as an LED. If the LED lights up after being powered on, it means that the produced twisted pair is undamaged and is a qualified product. If the LED does not light up after being powered on, it means that the produced twisted pair is damaged and is a defective product. This makes it easy to distinguish between qualified and unqualified products, so that unqualified twisted pairs can be removed.

[0032] See Figure 1 The slide rail 1 also includes a collection trough 12 located between and below the rails 11, so that after the rotating gripper unit 21 and the fixed gripper 32 open, the twisted pair cable that has completed the twisting operation will fall into the collection trough 12 for easy collection of the finished twisted pair cable; the push unit 33 is located on the rail 11 at one end away from the rotating component 2, and the self-testing twisting device also includes a controller (not shown in the figure). The push unit 33 is connected to the moving seat 31, and the push unit 33 is also electrically connected to the controller. The controller is also electrically connected to the gripper drive unit 22, so that when the gripper drive unit 22 drives the rotating gripper unit 21 to rotate, the controller controls the push unit 33 to push the moving seat 31 towards the rotating component 2, so that the cable will not be too taut during the twisting process, which would cause damage to the twisted pair cable.

[0033] The push unit 33 can be configured to include a screw and a rotary motor 221. The screw is arranged along the length of the track 11. The bottom of the moving seat 31 is provided with an internal thread structure that matches the screw. The screw is connected to the rotary motor 221, and the rotary motor 221 is electrically connected to the controller so that the moving seat 31 can be adjusted by controlling the forward and reverse rotation of the rotary motor 221.

[0034] The rotating gripper unit 21 also includes a movable gripper housing 212, a movable gripper body, and a movable gripper adjusting bolt 213. The movable gripper housing 212 has a movable gripper cable receiving groove 2121, a movable gripper cable through hole 2122 communicating with the movable gripper cable receiving groove 2121, and a movable gripper screw hole. The movable gripper cable receiving groove 2121 can accommodate a plug-in device provided at the end of the twisted pair cable. The movable gripper electrode plate 211 includes a movable electrode plate crimping section 2111 and a movable electrode plate abutting section 2112 adapted to abut against the end of the twisted pair cable and capable of conducting electricity. A movable electrode plate adjustment groove is formed on the electrode plate pressing section 2111. The movable claw adjustment bolt 213 can pass through the movable electrode plate adjustment groove and be screwed into the movable claw screw hole. The movable electrode plate abutting section 2112 is located in the movable claw cable receiving groove 2121 and can move closer to or away from the movable claw cable passing hole 2122 along the movable claw cable receiving groove 2121. The clamping end of the movable claw body is located at the movable claw cable passing hole 2122 so that when the twisted pair passes through the movable claw cable passing hole 2122 and abuts against the movable claw electrode plate 211, the movable claw body can clamp the twisted pair.

[0035] The movable jaw cable receiving groove 2121 can be used to accommodate the plug-in device provided at the end of the twisted pair cable, and the movable electrode plate adjustment groove can realize the movement and adjustment of the movable electrode plate abutment section 2112 in the movable jaw cable receiving groove 2121. This allows the distance between the movable electrode plate abutment section 2112 and the movable jaw cable through hole 2122 to be adjusted according to the size of the plug-in device provided at the end of the twisted pair cable. This ensures that the plug-in device can abut against the movable electrode plate abutment section 2112 to achieve conductivity, while also ensuring that the end of the twisted pair cable placed in the movable jaw cable receiving groove 2121 is not prone to large bending, so that the twisted pair cable is not easily bent and damaged.

[0036] The movable gripper electrode plate 211 can be made of rigid plastic sheet, and copper or iron plates can be embedded in the movable electrode plate contact section 2112 to enable the electrode plates embedded in the movable electrode plate contact section 2112 to conduct electricity, so that the current can pass through one cable of the twisted pair, the movable gripper electrode plate 211 and the other cable of the twisted pair in sequence to form a series circuit, so as to realize the power-on detection. The movable gripper electrode plate 211 made of rigid plastic sheet has the ability to insulate, which can ensure that no current is conducted between it and other adjacent components of the self-testing twisted wire device, thereby preventing leakage and electric shock. The power supply used for detection can be a DC power supply of V to ensure safety.

[0037] Figure 6 yes Figure 3 A cross-sectional view along the DD direction; Figure 7 yes Figure 4 See the enlarged view of region F in the middle. Figure 6 and Figure 7The movable gripper body includes a pair of movable gripper holding rods 214 and a pair of movable gripper driving connecting rods 215. A pair of movable gripper hinge seats 2123 are also provided on the movable gripper housing 212. A movable gripper hinge seat 2123 is provided on both sides of the movable gripper cable receiving groove 2121. One end of the movable gripper holding rod 214 is the gripping end, and the middle part of the movable gripper holding rod 214 is hinged to the movable gripper hinge seat 2123. The other end of the movable gripper holding rod 214 is hinged to one end of the movable gripper driving connecting rod 215. The other end of the movable gripper driving connecting rod 215 is provided with a movable gripper connecting post 2151. The movable gripper connecting post 2151 connects to the gripper driving unit 22 (e.g., Figure 3 As shown, the movable claw connecting post 2151 can move closer to or further away from the movable claw cable through hole 2122 under the drive of the claw driving unit 22. Specifically, when the movable claw connecting post 2151 moves closer to the movable claw cable through hole 2122, the distance between the clamping ends on the two movable claw clamping rods 214 will decrease to enable clamping of the twisted pair. When the movable claw connecting post 2151 moves away from the movable claw cable through hole 2122, the distance between the clamping ends on the two movable claw clamping rods 214 will increase to enable opening and removal of the twisted pair. Rubber pads can be provided on the clamping ends of the movable claw clamping rods 214 to prevent damage to the insulation of the twisted pair when clamping it.

[0038] Figure 8 yes Figure 3 See the enlarged view of region E in the middle. Figure 3 and Figure 8 The gripper drive unit 22 includes a rotary motor 221, a rotary shaft 222, a push rod 223, and a moving gripper push cylinder 224 (e.g., a pneumatic cylinder or a hydraulic cylinder). The rotary shaft 222 is connected to the moving gripper housing 212 and is also connected to the rotary motor 221 for transmission. Specifically, the rotary shaft 222 is provided with a driven gear, and the output shaft of the rotary motor 221 is provided with an output gear that matches the transmission gear. Through the cooperation of the driven gear and the output gear, the rotary motor 221 drives the rotary shaft 222 to rotate, thereby enabling the rotation of the rotating gripper unit 21.

[0039] Furthermore, the rotating shaft 222 is hollow, and the push rod 223 passes through the rotating shaft 222. One end of the push rod 223 is connected to the moving jaw connecting post 2151, and the other end of the push rod 223 is connected to the moving jaw pushing cylinder 224, so that the push rod 223 can be driven by the moving jaw pushing cylinder 224 to move closer to or away from the moving jaw cable through hole 2122. It is understood that a connecting sleeve 2241 needs to be set on the telescopic rod of the moving jaw pushing cylinder 224 to achieve the connection between the push rod 223 and the connecting sleeve 2241. Specifically, the connecting sleeve 2241 is set to be closed at one end and connected to the moving jaw pushing cylinder 224, and the other end of the connecting sleeve 2241 is open. The interior of the connecting sleeve 2241 is open at the top. The closed end of the mirror is provided with an abutment ring. The push rod 223 is provided with a limiting ring 2231 at one end inside the connecting sleeve 2241. Both sides of the limiting ring 2231 are provided with bearings. One of the two bearings can be abutted between the limiting ring 2231 and the abutment ring, and the other can be abutted between the retaining ring and the limiting ring 2231 by a retaining ring provided at the opening of the connecting sleeve 2241. This enables the push rod 223 to be rotatably connected to the connecting sleeve 2241, so that when the rotating gripper unit 21 rotates, the push rod 223 can rotate with it while the moving gripper pushes the cylinder 224 to remain stationary. The connecting sleeve 2241 can also drive the push rod 223 to move along the length of the push rod 223.

[0040] See Figure 4 and Figure 7 A moving claw sensor 4 is provided at the moving claw cable through hole 2122. The moving claw sensor 4 can be an infrared sensor and is suitable for detecting whether a twisted pair cable is passed through the moving claw cable through hole 2122. The moving claw sensor 4 is electrically connected to the controller so that when the moving claw sensor 4 detects that a twisted pair cable is passed through the moving claw cable through hole 2122, the controller can control the moving claw push cylinder 224 to drive the push rod 223 to reduce the distance between the clamping ends on the two moving claw clamping rods 214 to clamp the twisted pair cable.

[0041] Figure 9 yes Figure 4 See the enlarged view of region G in the middle. Figure 5 and Figure 9The fixed clamp 32 also includes a fixed clamp 32 housing, a fixed clamp 32 body, and a fixed clamp adjusting bolt 324; the fixed clamp 32 housing has a fixed clamp 32 cable receiving groove, a fixed clamp 32 cable passing hole communicating with the fixed clamp 32 cable receiving groove, and a fixed clamp 32 screw hole; the fixed clamp 32 cable receiving groove can be used to accommodate a plug-in device provided at the end of the twisted pair cable, and the fixed clamp 32 electrode plate includes a fixed electrode plate crimping section 3211 and a fixed electrode plate abutting section 3212 adapted to abut against the end of the twisted pair cable and capable of conducting electricity, and the fixed electrode plate... The contact section 3212 is located in the cable receiving groove of the fixed clamp 32 and can move closer to or further away from the cable passing hole of the fixed clamp 32 along the cable receiving groove of the fixed clamp 32. A fixed plate adjustment groove is formed on the fixed plate pressing section 3211. The fixed clamp adjustment bolt 324 can pass through the fixed plate adjustment groove and be screwed into the screw hole of the fixed clamp 32. The clamping end of the fixed clamp 32 body is located at the cable passing hole of the fixed clamp 32 so that when the twisted pair passes through the cable passing hole of the fixed clamp 32 and abuts against the electrode plate of the fixed clamp 32, the fixed clamp 32 body will clamp the twisted pair.

[0042] The fixed clamp 32 cable receiving slot can be used to accommodate the plug-in device set at the end of the twisted pair cable, and the fixed plate adjustment slot can realize the movement and adjustment of the fixed plate abutment section 3212 in the fixed clamp 32 cable receiving slot. This allows the distance between the fixed plate abutment section 3212 and the fixed clamp 32 cable through hole to be adjusted according to the size of the plug-in device set at the end of the twisted pair cable. This ensures that the plug-in device can abut against the fixed plate abutment section 3212 to achieve conductivity, while also ensuring that the end of the twisted pair cable placed in the fixed clamp 32 cable receiving slot is not prone to large bending, so that the twisted pair cable is not easily bent and damaged.

[0043] The fixed clamp 32 electrode plate can be made of rigid plastic plate. Specifically, the fixed electrode plate abutting section 3212 can be configured with two insertion holes 3213, and each insertion hole 3213 groove surface can be inlaid with a copper sheet or iron sheet or other electrode plate. Both electrode plates are electrically connected to the power supply, and an indicator 322 is connected in series between the power supply and one of the electrode plates. The two insertion holes 3213 can connect the plug-in devices at the ends of the two cables in the twisted pair to the corresponding electrode plates in the insertion holes 3213, thereby preventing short circuits.

[0044] See Figure 9The fixed gripper 32 body includes a pair of fixed gripper 32 clamping rods and a pair of fixed gripper 32 driving linkages. The fixed gripper 32 also includes a fixed gripper push cylinder 327. The fixed gripper 32 housing is also provided with a pair of fixed gripper 32 hinge seats. A fixed gripper 32 hinge seat is provided on both sides of the fixed gripper 32 cable receiving groove. One end of the fixed gripper 32 clamping rod is the clamping end. The middle part of the fixed gripper 32 clamping rod is hinged to the fixed gripper 32 hinge seat. The other end of the fixed gripper 32 clamping rod is hinged to one end of the fixed gripper 32 driving linkage. The other end of the fixed gripper 32 driving linkage is provided with a fixed gripper connecting post 3261. The fixed gripper connecting post 3261 is connected to the fixed gripper push cylinder 327 so that it can move closer to or further away from the fixed gripper 32 cable passing hole under the drive of the fixed gripper push cylinder 327, so as to adjust the distance between the clamping ends on the two fixed gripper 32 clamping rods.

[0045] Specifically, when the fixed claw connecting post 3261 moves toward the cable through hole of the fixed claw 32, the distance between the clamping ends on the two clamping rods of the fixed claw 32 will decrease to enable clamping of the twisted pair. When the fixed claw connecting post 3261 moves away from the cable through hole of the fixed claw 32, the distance between the clamping ends on the two clamping rods of the fixed claw 32 will increase to enable opening and removal of the twisted pair. Rubber pads can be provided on the clamping ends of the clamping rods of the fixed claw 32 to prevent damage to the insulation of the twisted pair when clamping it.

[0046] See Figure 6 and Figure 9 A fixed claw sensor 5 is provided at the cable through hole of the fixed claw 32. The fixed claw sensor 5 can be an infrared sensor. The fixed claw sensor 5 is suitable for detecting whether a twisted pair is inserted into the cable through hole of the fixed claw 32. The fixed claw sensor 5 is electrically connected to the controller so that when the fixed claw sensor 5 detects that a twisted pair is inserted into the cable through hole of the fixed claw 32, the controller controls the fixed claw push cylinder 327 to drive the fixed claw connecting column 3261 to reduce the distance between the clamping ends on the clamping rods of the two fixed claws 32 to clamp the twisted pair.

[0047] The working principle of the self-testing stranded wire device in this application is as follows: The two ends of the twisted pair are clamped by the rotating jaw unit 21 and the fixed jaw 32 respectively. After clamping, the rotating jaw unit 21 will drive the twisted pair to rotate under the drive of the jaw drive unit 22 to perform the twisting operation. The movable seat 31 can move on the track 11, thereby adjusting the distance between the movable seat 31 and the rotating component 2 to adapt to the twisting operation of cables of different sizes. In addition, the electrode plate of the fixed jaw 32, the indicator 322, the twisted pair, the moving jaw electrode plate 211 and the fixed jaw 32 electrode plate can form a series circuit. After the rotating jaw unit 21 stops rotating and completes the twisting operation, this series circuit can be connected to the power supply. Then, the quality problem of whether the produced twisted pair has damaged cores can be checked in time by whether the indicator 322 issues an indication signal.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
