[0002] A terminal block is an electrical component used to connect cables or wires. They usually consist of two or more metal conductors and are used to connect power sources, signals, and other electrical devices. Terminal blocks are widely used in industries such as industrial, automotive, and aerospace.

[0003] Before use, clean the terminal and the cable to remove any possible grease, dirt, and oxides. Then, at the contact point between the terminal block and the cable, strip off an insulating layer, correctly align the threaded part of the terminal, and then slowly rotate the terminal until it fully enters the cable. Then, tighten the terminal with a screwdriver, ensuring that the screws are evenly distributed on the terminal to balance the stress on the cable.

[0055] 1. In the present invention, through the setting of the anti-slip pattern, the relative sliding between the cable and the contact roller can be reduced. As the cable moves, the contact roller is driven to rotate. At this time, the contact roller drives the ratchet to rotate. The ratchet cooperates with the check pawl and continuously disengages from the check pawl. When the cable moves to the installation position, the contact roller stops rotating at this time, and the ratchet is fixed under the action of the check pawl, so as to fix the position of the cable through the contact roller.

[0056] 2. In the present invention, as the driven helical gear rotates, the driven helical gear drives the transmission rod to rotate, and the transmission rod drives the fixing bolt to rotate. The fixing bolt moves along the axis of the fixing bolt through the cooperation with the fixing nut until the end of the fixing bolt contacts the cable, so as to fix the position of the cable. Through the cooperation of the fixing bolt and the fixing nut, the position of the cable can be stably fixed, thereby reducing the influence of vibration on the stability of the connection, and it can be disassembled and assembled frequently without affecting the cable.

[0057] 3. In the present invention, after fixing the relative position of the cable and the crimping sleeve, it is also necessary to screw the tightening bolt into the locking nut until the tightening bolt moves the locking frame to the installation position. At this time, the locking frame abuts against the locking ring to fix the position of the rotating ring and reduce the influence of vibration on the stability of the connection between the cable and the crimping sleeve.

[0058] 4. In the present invention, through the setting of the positioning component, when the cable is installed in the crimping sleeve, it can avoid the problem of poor contact caused by the cable moving out of the installation position when fixing the cable. Through the cooperation of the fixing component and the driving component, the position of the fixing component can be freely adjusted, so as to facilitate the installation and disassembly of the cable without affecting the cable. Through the setting of the locking component, the influence of vibration on the connection stability between the cable and the crimping sleeve can be reduced, and the connection stability is improved.

Specific Embodiments

[0070] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0071] Such as Figures 1 to 9As shown in the figure, this embodiment proposes a non-crimp terminal, which includes a crimping sleeve 1. A crimping plate 2 is fixedly installed at the end of the crimping sleeve 1. It also includes a clamping ring 3, a positioning assembly, a positioning cylinder 4, a fixing frame 5, a fixing assembly, a driving assembly and a locking assembly. The clamping ring 3 is fixedly installed at the bottom end of the crimping sleeve 1. The positioning assembly is installed on the clamping ring 3 and is used to determine the position of the cable. The positioning assembly includes a positioning frame 6, a sliding groove 7, a sliding block 8, a check part, a contact part and a positioning part. Positioning frames 6 are fixedly installed on both sides of the clamping ring 3. Sliding grooves 7 are opened at both ends of the two positioning frames 6. A sliding block 8 is slidably installed on each sliding groove 7. A check part is installed between the two sliding blocks 8 on each positioning frame 6. The contact part is installed inside the check part and is used to contact the cable. The positioning part is installed on the check part and is used to fix the position of the contact part.

[0072] Specifically, when connecting cables and wires, it is necessary to according to the sizes of the crimping sleeve 1 and the cable, and then clean the terminal and the cable to remove possible grease, dirt and oxides. Then, at the contact part between the crimping sleeve 1 and the cable, strip an insulating layer so that current can flow safely through the connection. Then insert the cable into the inside of the crimping sleeve 1. At this time, through the setting of the positioning part, move the contact part to the working position and fix the position of the contact part. At this time, the contact part contacts the cable. As the cable continuously enters the crimping sleeve 1, the contact part moves accordingly. Through the setting of the check part, the cable can be positioned. When the end of the cable contacts the bottom of the crimping sleeve 1, through the setting of the fixing assembly and the locking assembly, fix the position of the cable.

[0073] As described above, as Figure 5 shown, the check part includes a housing 9 and a check pawl 10. A housing 9 is fixedly installed on each sliding block 8, and a check pawl 10 is fixedly installed inside each housing 9.

[0074] Specifically, as the contact part rotates, through the setting of the check pawl 10, the contact part cannot rotate in the reverse direction, thereby fixing the position of the cable.

[0075] As described above, as Figure 5 shown, the contact part includes a contact roller 11, anti-slip lines 12 and a ratchet wheel 13. A contact roller 11 is rotatably installed between the two housings 9 on each positioning frame 6. A plurality of anti-slip lines 12 are fixedly installed on each contact roller 11 in a circumferential and equiangular manner. A ratchet wheel 13 is fixedly installed at the upper and lower ends of each contact roller 11. The ratchet wheel 13 is located inside the housing 9, and the ratchet wheel 13 meshes with the check pawl 10.

[0076] Specifically, when the cable is inserted into the crimping sleeve 1, the cable contacts the contact roller 11. The anti-slip groove 12 can reduce the relative sliding between the cable and the contact roller 11. As the cable moves, the contact roller 11 is driven to rotate. At this time, the contact roller 11 drives the ratchet 13 to rotate. The ratchet 13 cooperates with the non-return pawl 10 and continuously disengages from the non-return pawl 10. When the cable moves to the installation position, the contact roller 11 stops rotating and the ratchet 13 is fixed by the non-return pawl 10, thereby fixing the position of the cable through the contact roller 11.

[0077] The above, such as Figure 5 As shown, the positioning portion includes an arc groove 14 and an arc frame 15. Two arc grooves 14 are symmetrically opened on both sides of each slide groove 7. Each two opposite arc grooves 14 are symmetrically arranged. An arc frame 15 is rotatably installed on each slider 8, and both ends of the arc frame 15 are adapted to the arc groove 14.

[0078] Specifically, before connecting the cable, the arc frame 15 is at the arc groove 14 away from the crimping sleeve 1, and the contact roller 11 does not contact the cable. When plugging the cable, the arc frame 15 is moved to move the arc frame 15 out of the arc groove 14, and then the arc frame 15 is held to push the slider 8 to move on the slide groove 7 until the arc frame 15 moves to the arc frame 15 close to the crimping sleeve 1, and then the arc frame 15 is screwed into the arc groove 14 to fix the position of the contact roller 11. At this time, the position of the contact roller 11 is in contact with the cable.

[0079] like Figure 6 As shown, two positioning cylinders 4 are symmetrically and fixedly installed on the crimping sleeve 1, the fixing frame 5 is fixedly installed between the two positioning cylinders 4, the fixing assembly is installed inside the positioning cylinder 4, and is used to fix the position of the cable. The fixing assembly includes a rotating ring 16, a driving part and a wire crimping part. The rotating ring 16 is rotatably installed between the two positioning cylinders 4, the driving part is installed on the rotating ring 16, and the wire crimping part is installed on the driving part for crimping.

[0080] Specifically, when the end of the cable moves to the installation position inside the crimping sleeve 1, the driving part is set to drive the rotating ring 16 to rotate. At this time, the rotation of the rotating ring 16 can drive the wire crimping part to move, thereby fixing the position of the cable.

[0081] The above, such as Figure 6 As shown, the driving part includes a driven bevel gear 17 and a driving bevel gear 18. A plurality of driven bevel gears 17 are installed in the two positioning cylinders 4 in a circular and equiangular manner. Driving bevel gears 18 are fixedly installed at both ends of the rotating ring 16, and the driving bevel gears 18 are meshed with the driven bevel gears 17.

[0082] Specifically, when installing the cable, by rotating the rotating ring 16, the driving helical gear 18 is driven to rotate. The driving helical gear 18 drives the driven helical gear 17 to rotate, so that the cable can be fixed by driving the driven helical gear 17 to rotate.

[0083] As described above, Figure 7 As shown in the figure, the wire pressing part includes a fixing cylinder 19, a fixing nut 20, a fixing bolt 21 and a transmission rod 22. A fixing cylinder 19 is arranged on each driving helical gear 18, and a plurality of fixing cylinders 19 are fixedly installed on the crimping sleeve 1. A fixing nut 20 is fixedly installed at the end of each fixing cylinder 19, a fixing bolt 21 is threadedly installed inside each fixing nut 20, a transmission rod 22 is slidably installed on each fixing bolt 21, and a plurality of transmission rods 22 correspond to a plurality of driven helical gears 17 one by one. The transmission rod 22 is fixedly connected to the driven helical gear 17.

[0084] Specifically, as the driven helical gear 17 rotates, the driven helical gear 17 drives the transmission rod 22 to rotate, the transmission rod 22 drives the fixing bolt 21 to rotate, and through the cooperation of the fixing bolt 21 and the fixing nut 20, the fixing bolt 21 moves along the axis direction of the fixing bolt 21 until the end of the fixing bolt 21 contacts the cable, so as to fix the position of the cable. Through the cooperation of the fixing bolt 21 and the fixing nut 20, the position of the cable can be stably fixed, thereby reducing the influence of vibration on the connection stability, and reducing the influence on the cable during frequent disassembly and assembly.

[0085] As Figure 6 shown in the figure, the driving assembly is installed on the fixing frame 5 and is used to drive the fixing assembly to act. The driving assembly includes a worm gear 23, a worm 24 and a joint 25. The worm gear 23 is fixedly installed on the rotating ring 16, the worm 24 is rotatably installed on the fixing frame 5, the worm 24 meshes with the worm gear 23, and a joint 25 is fixedly installed at one end of the worm 24. The joint 25 is rotatably matched with the fixing frame 5.

[0086] Specifically, when driving the rotating ring 16 to rotate, a tool such as a wrench is connected to the joint, and then the worm 24 is rotated, and the worm 24 drives the worm gear 23 to rotate, so that the rotating ring 16 can be driven to rotate.

[0087] As Figure 9As shown in the figure, the locking component is installed on the fixing bracket 5 and is used to fix the driving component. The locking component includes a locking ring 26, a locking bracket 27, a return spring 28, a locking nut 29 and a fastening bolt 30. Locking rings 26 are fixedly installed at both ends of the worm gear 23. A locking bracket 27 is slidably installed on the fixing bracket 5. The locking bracket 27 is adapted to the locking ring 26. A return spring 28 is fixedly installed between the fixing bracket 5 and the locking bracket 27. The locking nut 29 is fixedly installed on the fixing bracket 5. The fastening bolt 30 is threadedly installed on the locking nut 29. The end of the fastening bolt 30 abuts against the locking bracket 27.

[0088] Specifically, after fixing the relative positions of the cable and the crimping sleeve, the fastening bolt 30 needs to be screwed into the locking nut 29 until the fastening bolt 30 moves the locking bracket 27 to the installation position. At this time, the return spring 28 is stretched, and the locking bracket 27 abuts against the locking ring 26, thereby fixing the position of the rotating ring 16, reducing the stability of the vibration during the cooperation between the cable and the crimping sleeve. And when disassembling the crimping sleeve, after removing the fastening bolt 30, the locking bracket 27 can be disengaged from the locking ring 26, and the return spring 28 returns to its original position.

[0089] To sum up, when connecting cables and wires, it is necessary to select according to the sizes of the crimping sleeve 1 and the cable, then clean the terminals and the cable to remove any possible grease, dirt and oxides. Then, at the contact between the crimping sleeve 1 and the cable, strip off an insulating layer to enable current to flow safely through the connection. Then insert the cable into the inside of the crimping sleeve 1. Before connecting the cable, at this time, the arc-shaped bracket 15 is away from the arc-shaped groove 14 of the crimping sleeve 1, and at this time, the contact roller 11 does not contact the cable. When inserting the cable, move the arc-shaped bracket 15, move the arc-shaped bracket 15 out of the arc-shaped groove 14, then hold the arc-shaped bracket 15 and push the slider 8 to move on the chute 7 until the arc-shaped bracket 15 moves to the arc-shaped bracket 15 close to the crimping sleeve 1, and then screw the arc-shaped bracket 15 into the arc-shaped groove 14 to fix the position of the contact roller 11. At this time, the position of the contact roller 11 abuts against the cable.

[0090] When the cable is inserted into the crimping sleeve 1, the cable contacts the contact roller 11. Through the setting of the anti-slip lines 12, the relative sliding between the cable and the contact roller 11 can be reduced. As the cable moves, the contact roller 11 is driven to rotate. At this time, the contact roller 11 drives the ratchet wheel 13 to rotate. The ratchet wheel 13 cooperates with the check pawl 10 and continuously disengages from the check pawl 10. When the cable moves to the installation position, at this time, the contact roller 11 stops rotating, and the ratchet wheel 13 is fixed under the action of the check pawl 10, thereby fixing the position of the cable through the contact roller 11.

[0091] After the end of the cable moves to the installation position inside the crimping sleeve 1, it is necessary to fix the position of the cable. At this time, a tool such as a wrench is connected and then the worm 24 is rotated. The worm 24 drives the worm wheel 23 to rotate, thereby driving the rotating ring 16 to rotate. Through the rotation of the rotating ring 16, the driving bevel gear 18 is driven to rotate. The driving bevel gear 18 drives the driven bevel gear 17 to rotate, thereby driving the driven bevel gear 17 to rotate.

[0092] As the driven bevel gear 17 rotates, the driven bevel gear 17 drives the transmission rod 22 to rotate. The transmission rod 22 drives the fixing bolt 21 to rotate. The fixing bolt 21 moves along the axis direction of the fixing bolt 21 through the cooperation with the fixing nut 20 until the end of the fixing bolt 21 contacts the cable, thereby fixing the position of the cable. Through the cooperation of the fixing bolt 21 and the fixing nut 20, the position of the cable can be stably fixed, thereby reducing the influence of vibration on the stability of the connection, and the influence on the cable can be reduced during frequent disassembly and assembly.

[0093] After fixing the relative position of the cable and the crimping sleeve, it is also necessary to screw the fastening bolt 30 into the locking nut 29 until the fastening bolt 30 moves the locking frame 27 to the installation position. At this time, the return spring 28 is stretched, and the locking frame 27 abuts against the locking ring 26, thereby fixing the position of the rotating ring 16, reducing the vibration on the stability when the cable and the crimping sleeve are matched, and when disassembling the crimping sleeve, after removing the fastening bolt 30, the locking frame 27 can be disengaged from the locking ring 26, and the return spring 28 returns to its original position.

[0094] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
