Description

Technical Field

[0001] The present invention relates to the technical field of cable terminal connection, and specifically to an automatic insertion device for cable assemblies. Background Art

[0002] A cable terminal is a commonly used component for connecting a cable to an electrical device or system. It is usually made of a metal material with good electrical conductivity. The cable terminal can ensure the reliability and safety of the electrical connection. The connection quality between the cable and the terminal is crucial and directly related to the normal use of the electrical system. Commonly, an insertion connection method is used to connect the cable and the terminal. This method is simple and convenient. During the process of connecting the terminal and the cable, it is necessary to cut a suitable length of the cable and strip the insulation layer at the end of the cable to expose the internal wire harness conductor. Then, the exposed wire harness conductor is inserted into the terminal slot to complete the stable connection between the cable terminal and the cable.

[0003] However, there are still the following problems in the process of inserting the wire harness conductor into the cable terminal: (1) It is not easy to control the stripping length of the cable sheath and the cutting depth. If the stripping length is too long, the wire harness conductor will remain outside the terminal, affecting normal use and safety. If the stripping length is insufficient, the connectivity and stability between the cable and the terminal will be poor. If the cutting depth is too deep, the wire harness conductor may be damaged, affecting the quality of the wire harness conductor. If the cutting depth is insufficient, the difficulty of stripping the cable sheath will increase due to the adhesion between the cable sheaths.

[0004] (2) The part of the wire harness conductor after stripping is easily changed from the tight state before stripping to a slightly divergent state. The slightly divergent state is not conducive to the neat and rapid insertion of the wire harness conductor into the terminal slot, resulting in an increase in the installation difficulty and prone to the situation of bending and deforming the wire harness conductor.

[0005] (3) The degree of insertion of the wire harness conductor into the terminal is insufficient, and the sufficiency and tightness of the connection between the two need to be improved, thereby reducing the reliability of the overall connection quality. Summary of the Invention

[0016] Advantages of the present invention: 1. The control component in the present invention can control the cutting depth of the peeling knife according to the thickness of the cable sheath.

[0017] 2. The present invention limits and clamps the exposed wire harness conductors after peeling through the clamping assembly, which can effectively prevent the wire harness conductors after peeling from being difficult to insert into the terminal slot due to spreading outwards, increasing the neatness of the wire harness. At the same time, the clamping assembly can maintain the limiting state of the wire harness conductors and move in the opposite direction relative to the cable after the cable is inserted into the terminal slot, so as to ensure that the wire harness conductors are quickly and smoothly inserted into the terminal slot in a neat state, thereby improving the reliability and stability of the connection.

The peeling assembly adopted by the present invention can use the peeling knife to complete the circumferential cutting of the cable sheath at one time, which can not only ensure the cutting efficiency of the cable sheath, but also be beneficial to the neatness and consistency of the cut of the cable sheath. In addition, the arc-shaped push plate and the arc-shaped pressing plate can perform circumferential pressing and supporting on the cable during the cutting process, which can increase the straightness of the cable while ensuring the stability of the cable, thereby improving the overall peeling quality and efficiency. In addition, the present invention can screw the cut cable sheath away from the wire harness conductors to complete peeling efficiently, and can also make the wire harness conductors fully and tightly inserted into the terminal slot by screwing, thereby increasing the connection strength between the cable and the terminal and improving the overall working efficiency.

However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0033] Please refer to Figure 1 , an automatic cable assembly insertion device, including a processing table 1, and a fixing unit 2 for fixing terminals and cables is provided at the upper end of the processing table 1.

[0034] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 10 , the fixing unit 2 includes an arc-shaped frame 21 installed at the upper left end of the processing table 1. An arc-shaped plate 211 is rotatably installed inside the arc-shaped frame 21. A fixing plate 212 is installed between the front and rear ends of the arc-shaped plate 211. A clamping member one is provided at the upper end of the fixing plate 212. The clamping member one includes a positioning column installed at the upper end of the fixing plate 212. A sliding groove one is opened at the upper end of the fixing plate 212 on the right side of the positioning column. Two arc-shaped clamping plates 214 slidably connected to the front and rear of the sliding groove one are provided at the upper end of the fixing plate 212. A bidirectional electric telescopic rod one 215 installed in the sliding groove one is connected between the front and rear arc-shaped clamping plates 214. A fixing groove is opened at the upper end of the front arc-shaped clamping plate 214. A clamping plate 217 matched with the fixing groove is installed at the front end of the rear arc-shaped clamping plate 214. A rotating plate 218 is rotatably installed inside the fixing groove through a torsion spring shaft. A moving frame 22 is slidably installed left and right at the upper end of the processing table 1 on the right side of the arc-shaped frame 21. A clamping member two is provided at the upper right end of the moving frame 22. The clamping member two includes a sliding groove two opened at the upper end of the moving frame 22. Two arc-shaped pressing plates 221 slidably connected to the front and rear of the sliding groove two are provided at the upper end of the moving frame 22. A bidirectional electric telescopic rod two 222 installed in the sliding groove two is connected between the front and rear arc-shaped pressing plates 221. The arc-shaped clamping plates 214 and the arc-shaped pressing plates 221 are concentric with the arc-shaped frame 21.

[0035] During operation: First, the terminals required for connection can be horizontally placed on the upper end of the fixed plate 212 with the openings facing right, and the connection holes on the left ends of the terminals are passed through the positioning posts. The placement of the terminals is initially positioned through the cooperation between the positioning posts and the connection holes. Then, the two front and rear arc-shaped clamping plates 214 can be controlled by the bidirectional electric telescopic rod 215 to move synchronously towards each other to clamp the terminals. At this time, the clamping plate 217 moves with the rear arc-shaped clamping plate 214 to abut against the rotating plate 218, and the rotating plate 218 is in a vertical state at this time. While placing the terminals, the cables required for connection are horizontally placed on the upper end of the moving frame 22, and the two front and rear arc-shaped abutting plates 221 are controlled by the bidirectional electric telescopic rod 222 to move synchronously towards each other to clamp the cables, thus completing the fixation of the terminals and the cables.

[0036] Please refer to Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in, an opening groove 3 is provided on the left side of the moving frame 22. Inside the opening groove 3, a cable stripping assembly for stripping the cable skin and a tightening assembly for limiting and tightening the conductor of the wire harness after stripping are sequentially arranged from left to right. The cable stripping assembly includes a vertical plate 31. An annular sleeve 311 is rotatably installed on the vertical plate 31. An electric push rod 312 is installed on the upper end of the outer ring surface of the annular sleeve 311. A cable stripping knife 313 that is slidably connected to the annular sleeve 311 up and down is arranged on the right side of the electric push rod 312. A connecting plate is connected between the upper end of the pushing end of the electric push rod 312 and the upper end of the cable stripping knife 313. Two arc-shaped pushing plates 314 that are distributed front and rear and are located below the left side of the cable stripping knife 313 are arranged inside the annular sleeve 311. Two arc-shaped pressing plates 315 that are distributed up and down and are located on the right side of the cable stripping knife 313 are arranged inside the annular sleeve 311. Push rods 316 that are slidably connected to the annular sleeve 311 are installed on the outer sides of the arc-shaped pushing plates 314 and the arc-shaped pressing plates 315. The push rods 316 slidably penetrate through the annular sleeve 311 and then a baffle 317 is installed. A connecting spring located between the corresponding baffle 317 and the outer ring surface of the annular sleeve 311 is sleeved on the outer part of the push rod 316. Link rods 319 that are hinged to the corresponding baffles 317 located on the front and rear sides of the annular sleeve 311 are hinged to the front and rear ends of the connecting plate. Uniformly arranged rollers 320 are rotatably installed on the side where the two front and rear arc-shaped pushing plates 314 are close to each other.

[0037] Please refer to Figure 1 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9, a control component for controlling the peeling length and depth is provided on the left side of the vertical plate 31. The control component includes a mounting plate opposite to the peeling knife 313 installed at the lower end of the outer ring surface of the annular sleeve 311. A threaded telescopic rod 322 is installed at the left end of the mounting plate. The telescopic end of the threaded telescopic rod 322 is rotatably installed with a limiting plate 323. A guiding telescopic rod 324 is connected between the limiting plate 323 and the annular surface at the left end of the annular sleeve 311. An adjusting plate 325 is installed at the upper end of the outer ring surface of the annular sleeve 311 on the left side of the electric push rod 312. A control plate 326 is provided at the right end of the adjusting plate 325. A plurality of jacks 327 are evenly arranged up and down on the adjusting plate 325. The control plate 326 is inserted and matched with the corresponding jacks 327 through inserting rods. A rotating component for driving the peeling component to rotate is provided on the right side of the vertical plate 31. The rotating component includes a gear ring 328. The right end of the annular sleeve 311 penetrates through the vertical plate 31 and is installed with the gear ring 328. The upper end of the gear ring 328 is meshed with a rotating gear 329 rotatably connected to the vertical plate 31. The right end of the rotating gear 329 is connected to the output shaft of the motor 330. The motor 330 is installed on the right end of the vertical plate 31 through a support.

[0038] During operation: Before placing the cable, first adjust the length of the subsequent cable peeling according to the depth of the internal slot of the terminal. Specifically: Rotate the threaded telescopic rod 322 to move the limiting plate 323 to the left and stretch the guiding telescopic rod 324, and ensure that the distance between the right end face of the limiting plate 323 and the left end face of the mounting plate is the same as the depth of the slot. The mounting plate is opposite to the position of the peeling knife 313, so that the peeling knife 313 is in an accurate and appropriate cutting position. Controlling the length of the cable peeling by the limiting plate 323 is beneficial to the subsequent exposed wire harness conductors being completely inserted into the internal slot of the terminal, avoiding the wire harness conductors being too long and remaining outside the terminal, affecting normal use and safety. At the same time, it can also prevent the problem of poor connectivity and low stability of the wire harness conductors inserted into the terminal due to insufficient length; Subsequently, the cutting depth of the subsequent peeling knife 313 can be adjusted according to the thickness of the cable sheath. Specifically: Move the control plate 326 up and down along the adjusting plate 325, and ensure that the distance between the connecting plate and the control plate 326 is the same as the thickness of the cable sheath. After the control plate 326 is adjusted to the appropriate position, the control plate 326 can be fixed on the adjusting plate 325 through the cooperation between the inserting rod and the jack 327. Use the control plate 326 to limit the distance that the connecting plate moves towards the cable, and then control the cutting depth of the peeling knife 313 for the cable sheath. This can not only ensure that the cable sheath is cut fully and effectively, facilitating the subsequent smooth removal of the cable sheath, but also avoid the peeling knife 313 over-cutting and damaging the wire harness conductors, ensuring the quality of the wire harness conductors.

[0039] During the process of placing the cable, the left end of the cable can be towed from right to left through the vertical plate 31 and the annular sleeve 311 until the left end of the cable abuts against the limit plate 323. At this time, the length of the cable between the stripping knife 313 and the limit plate 323 is exactly the required stripping length. During the process of the cable passing through the annular sleeve 311, the cable can also be successively passed between the upper and lower arc-shaped pressing plates 315 and between the front and rear arc-shaped pushing plates 314. The upper and lower arc-shaped pressing plates 315 and the front and rear arc-shaped pushing plates 314 can all elastically clamp the cable through the cooperation between the corresponding push columns 316, the connecting springs and the baffle plates 317. Moreover, the upper and lower arc-shaped pressing plates 315 are clamped on the right side of the cable skin cutting position, and the front and rear arc-shaped pushing plates 314 are clamped on the left side of the cable skin cutting position. Through the cooperation between the arc-shaped pressing plate 315 and the arc-shaped pushing plate 314, the cable can be circumferentially pressed and limitedly supported, which can not only increase the fulcrums of the cable, further improve the stability of the cable, ensure the smooth progress of the stripping operation, but also ensure the neatness and straightness of the wire harness conductors during the process of cutting the cable skin.

[0040] After the cable is fixed, the electric push rod 312 can drive the stripping knife 313 to move downward along the annular sleeve 311 through the connecting plate and gradually cut into the cable skin until the connecting plate abuts against the control plate 326. At this time, the stripping knife 313 just completely and fully cuts into the cable skin and does not contact the wire harness conductors. Then, the rotating gear 329 can be driven to rotate by the motor 330. The rotating gear 329 drives the annular sleeve 311, the stripping assembly and the control assembly to rotate synchronously around the cable circumferentially for one week through the gear ring 328. During this process, the stripping knife 313 can perform circumferential cutting on the cable skin, so that the cable skin to be stripped is completely cut off. The arc-shaped pressing plate 315 and the arc-shaped pushing plate 314 both rotate synchronously around the cable with the annular sleeve 311 and continuously perform circumferential pressing and supporting on the cable. Subsequently, the electric push rod 312 can push the stripping knife 313 to move upward and reset through the connecting plate until the stripping knife 313 is far away from the cable. Then, the electric push rod 312 can continue to push the connecting plate and the stripping knife 313 to move upward. The connecting plate drives the corresponding baffle plates 317 and push columns 316 to move synchronously in the direction of the axis of the annular sleeve 311 through the connecting rods 319 on its front and rear sides. The push column 316 drives the corresponding arc-shaped pushing plate 314 to further clamp the cable skin to be stripped by compressing the connecting spring. Moreover, the arc-shaped pushing plate 314 clamps the cable through the uniformly arranged rollers 320. The uniformly arranged rollers 320 not only help the arc-shaped pushing plate 314 to rotate circumferentially and press the cable, but also increase the axial friction force between the arc-shaped pushing plate 314 and the cable skin, ensuring that the cable skin can be smoothly separated from the wire harness conductors subsequently.

[0041] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 9 andFigure 10 The clamping assembly includes a moving plate 32 located on the right side of the vertical plate 31. Above the moving plate 32, there are two arc-shaped mating plates 331 distributed up and down and clamped with each other. An arc-shaped moving groove is formed on the right side of the arc-shaped mating plate 331, and the radius of the arc-shaped moving groove is greater than the radius of the arc-shaped mating plate 331. An arc-shaped auxiliary plate 346 located on the left side of the arc-shaped moving groove is installed on the inner ring surface of the arc-shaped mating plate 331 through uniformly arranged auxiliary springs. A positioning rod 332 is installed on the front side of the left end of the upper arc-shaped mating plate 331 and the rear side of the left end of the lower arc-shaped mating plate 331. Positioning holes 333 matching the corresponding positioning rods 332 are formed at the right ends of the front and rear arc-shaped clamping plates 214. A moving assembly for driving the two arc-shaped mating plates 331 to move synchronously and in opposite directions is arranged at the upper end of the moving plate 32. The moving assembly includes rectangular plates 334 installed on the sides where the two arc-shaped mating plates 331 are away from each other. A vertical plate 335 is arranged at the upper end of the moving plate 32 and located in front of the upper and lower rectangular plates 334. Vertical racks 336 slidably connected to the vertical plate 335 up and down are installed on the left side of the front end of the upper rectangular plate 334 and the right side of the front end of the lower rectangular plate 334. A connecting gear 337 rotatably connected to the vertical plate 335 is meshed between the left and right vertical racks 336. A moving gear 338 is coaxially installed at the front end of the connecting gear 337. A fixed rack 339 meshing with the moving gear 338 is installed at the upper front end of the moving frame 22. An installation groove is formed at the upper end of the moving plate 32. The vertical plate 335 is installed at the upper end of an inner plate 341 slidably connected to the installation groove left and right. Two spring rods 342 fixedly connected to the groove wall of the installation groove and arranged front and back are slidably installed at the right end of the inner plate 341. A vertical rod slidably connected to the upper and lower rectangular plates 334 is installed at the upper rear end of the inner plate 341. A side rod 344 located below the moving gear 338 is installed at the front end of the vertical plate 335. A fixed column 345 corresponding to the side rod 344 is installed at the right end of the arc-shaped frame 21.

[0042] Please refer to Figure 1 、 Figure 2 、 Figure 6 、 Figure 9 and Figure 10, a driving component for driving the peeling component to move up and down is arranged on the moving plate 32. The driving component includes a top plate 351 installed at the upper end of the vertical plate 31 and located above the tightening component. At the upper end of the moving plate 32, two vertical guide rails 352 arranged front and back and located on the right side of the vertical plate 31 and slidably connected to the top plate 351 up and down are installed. Electric sliders fixedly connected to the top plate 351 are slidably installed on the vertical guide rails 352. Side plates are installed on both the front and back sides of the top plate 351. Support rods 354 slidably connected to the side plates up and down are slidably installed left and right at positions corresponding to the side plates on the upper end of the processing table 1. A sealing plate located above the top plate 351 is connected between the upper ends of the support rods 354 and the vertical guide rails 352. A linkage component for driving the moving frame 22, the peeling component and the tightening component to move left and right is arranged on the upper end of the processing table 1. The linkage component includes a transverse guide rail 355 installed on the upper end of the processing table 1. An electric sliding plate 356 fixedly connected to the moving plate 32 is slidably installed on the transverse guide rail 355. An automatic push rod 357 with a pushing end fixedly connected to the moving frame 22 is installed on the upper end of the processing table 1 and located in front of the moving frame 22. Guide blocks are installed on both the front and back sides of the arc-shaped frame 21. Guide columns 358 slidably connected to the corresponding guide blocks left and right are installed at the left end of the moving frame 22.

[0043] During operation: After the front and rear arc-shaped push plates 314 press against the cable section on the left side of the incision, the electric sliding plate 356 can drive the moving plate 32, the tightening component, the driving component and the peeling component to move leftward as a whole along the transverse guide rail 355. At the same time, the peeling component can be controlled to rotate through the rotating component. Both the front and rear arc-shaped push plates 314 can drive the cable skin edge on the left side of the incision to rotate and move leftward through the evenly arranged rollers 320 until the cable skin completely rotates away from the wire harness conductor, exposing the wire harness conductor. Then, the peeled cable skin can be manually removed from the peeling component. The electric sliding plate 356 continues to drive the peeling component and the tightening component to move leftward along the transverse guide rail 355 until the peeling component moves away from the left end of the cable. Subsequently, the front and rear electric sliders can simultaneously drive the top plate 351 to move upward along the corresponding vertical guide rails 352 until the top plate 351 drives the vertical plate 31 and the peeling component to move upward away from the cable as a whole. When the peeling component moves leftward, the top plate 351 can drive the support rods 354 to move synchronously along the processing table 1 through the side plates on its front and back sides. When the peeling component moves upward, the top plate 351 can move upward synchronously along the corresponding support rods 354 through the side plates on its front and back sides. The cooperation between the support rods 354 and the side plates can support and guide the movement of the peeling component, ensuring the stability of the peeling and movement processes of the peeling component.

[0044] During the process of the peeling component moving leftward, the moving plate 32 can drive the vertical plate 335, the vertical rod, the tightening component and the moving component to move synchronously through the inner plate 341. Moreover, the moving gear 338 gradually meshes with the fixed rack 339 on the moving frame 22. Since the moving frame 22 is in a stationary state at this time, the moving gear 338 can drive the connecting gear 337 to rotate counterclockwise synchronously. The connecting gear 337 can drive the vertical racks 336 on its left and right sides to move synchronously and in opposite directions along the vertical plate 335. The upper rectangular plate 334 and the arc-shaped matching plate 331 move downward along the vertical rod, and the lower rectangular plate 334 and the arc-shaped matching plate 331 move upward along the vertical rod until the upper and lower arc-shaped matching plates 331 are clamped and matched, and the clamping and matching of the upper and lower arc-shaped matching plates 331 is carried out simultaneously with the peeling of the cable skin. When the peeling component moves away from the left end of the cable, the upper and lower arc-shaped matching plates 331 can just limit and tighten the wire harness conductor from the upper and lower sides thereof by compressing the auxiliary spring, which can effectively prevent the wire harness conductor after peeling from opening outward, ensure that the wire harness conductor can be smoothly and efficiently inserted into the terminal, and there is a certain distance between the arc-shaped matching plate 331 and the left and right ends of the exposed wire harness conductor.

[0045] Then, the electric sliding plate 356 can continue to drive the moving plate 32 and the tightening component to move leftward. At the same time, the automatic push rod 357 drives the moving frame 22, the second clamping member and the cable in a fixed state to move leftward synchronously. The guiding columns 358 on the front and rear sides of the moving frame 22 can move leftward along the corresponding guiding blocks to guide the leftward movement of the moving frame 22 and the cable. During this process, the left end of the wire harness conductor in a tightened state gradually inserts into the right end of the terminal, the arc-shaped matching plate 331 gradually abuts against the right end of the terminal, and the alignment rods 332 at the left ends of the upper and lower arc-shaped matching plates 331 gradually insert into the corresponding alignment holes 333 at the right ends of the front and rear arc-shaped clamping plates 214. The cooperation between the alignment rod 332 and the alignment hole 333 can conduct alignment and guidance for the leftward movement of the tightening component and the wire harness conductor to ensure that the wire harness conductor is accurately inserted into the slot at the right end of the terminal. In addition, the side rod 344 on the front side of the vertical plate 335 gradually abuts against the fixed column 345 at the right end of the arc-shaped frame 21. The side rod 344 is pressed to drive the vertical plate 335 to move. The vertical plate 335 drives the inner plate 341 to compress the spring rod 342 along the installation groove. The tightening component and the moving component as a whole move rightward synchronously with the inner plate 341. The moving frame 22 drives the cable to move leftward relative to the tightening component through the second clamping member, and the cable at the right end of the exposed wire harness conductor can enter the arc-shaped moving groove on the right side of the arc-shaped matching plate 331. Since the moving frame 22 and the fixed rack 339 move leftward at this time, while the moving gear 338 in the moving component moves rightward, the moving gear 338 remains in meshing with the fixed rack 339 and rotates clockwise.

[0046] Please refer to Figure 1 、 Figure 2 、Figure 3 and Figure 5 On the upper end of the processing table 1, there is a rotating assembly for controlling the rotation of the arc plate 211. The rotating assembly includes an arc rack 111 installed inside the arc plate 211. An adjusting gear 112 is engaged with the upper end of the arc rack 111. A circular through groove is opened at the center of the adjusting gear 112, and a spiral groove 113 is opened on the inner wall of the circular through groove. A rotating cylinder rotatably connected to the processing table 1 is installed at the left end of the adjusting gear 112. A support plate 114 slidably connected to the processing table 1 in the left-right direction is arranged on the right side of the arc-shaped frame 21. A telescopic spring 115 is connected between the support plate 114 and the arc-shaped frame 21. A moving rod 116 matched with the circular through groove is installed at the left end of the arc-shaped frame 21. A matching column matched with the spiral groove 113 is installed at the left end of the moving rod 116. L-shaped push plates 117 corresponding to the ends of the support plate 114 are installed on both the front and rear sides of the moving frame 22.

[0047] Please refer to Figures 1 - 10 , during operation: Under the action of the moving assembly, the upper and lower arc-shaped matching plates 331 gradually move synchronously and reversely away from the wire harness conductor, but the arc-shaped auxiliary plate 346 always maintains elastic limitation on the wire harness conductor. At this time, there is still a small section of the wire harness conductor that has not been fully inserted into the slot at the right end of the terminal. Subsequently, the moving frame 22 and the cable can continue to move leftward. The moving frame 22 drives the L-shaped push plates 117 on both the front and rear sides to press the support plate 114 leftward. The support plate 114 drives the moving rod 116 to move leftward along the processing table 1 by compressing the telescopic spring 115. While the moving rod 116 moves leftward, the matching column gradually cooperates with the spiral groove 113 on the adjusting gear 112. Under the cooperation of the moving rod 116, the matching column and the spiral groove 113, the adjusting gear 112 gradually drives the rotating cylinder to rotate. The arc rack 111 drives the arc plate 211 to rotate synchronously along the arc-shaped frame 21 with the adjusting gear 112. The arc plate 211 drives the clamping member one and the terminal in a fixed state to rotate synchronously through the fixing plate 212. While the cable moves leftward, the terminal rotates until the wire harness conductor is fully and completely screwed into the terminal. Then, the front and rear arc-shaped clamping plates 214 can be controlled to continue moving towards each other synchronously through the bidirectional electric telescopic rod one 215. The clamping plate 217 moves forward synchronously with the rear arc-shaped clamping plate 214 and gradually presses the rotating plate 218, causing the rotating plate 218 to rotate forward around the torsion spring axis. At this time, the front and rear arc-shaped clamping plates 214 can press the terminal with the wire harness conductor inserted to perform crimping, ensuring a tighter and more stable connection between the wire harness conductor and the terminal.

[0048] After completing the connection of the cable and the terminal, the clamping of the terminal and the cable by the first clamping member and the second clamping member can be released first in the reverse manner described above. Under the action of the positioning post, the terminal still remains at the upper end of the fixing plate 212, while the cable always remains at the upper end of the moving frame 22. Then, the moving frame 22 can be pushed to move rightward by the automatic push rod 357. The support plate 114 drives the moving rod 116 to move rightward synchronously with the matching post and makes the fixing plate 212, the first clamping member and the terminal rotate and reset to the horizontal state. While the moving frame 22 moves rightward, the tightening assembly can be moved rightward. Under the cooperation of the fixed rack 339 and the moving gear 338, the upper and lower arc-shaped matching plates 331 gradually move synchronously in the opposite direction to the reset state. Then, the connected cable and terminal can be removed. Then, the stripping assembly can be lowered to reset. Finally, the tightening assembly, the stripping assembly and the moving frame 22 can be moved rightward to reset as a whole.
