DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 9 As shown, this embodiment proposes a crimp-free terminal, including a crimping sleeve 1, a crimping plate 2 fixedly installed at the end of the crimping sleeve 1, 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, and the positioning assembly is installed on the clamping ring 3 to determine the position of the cable. The positioning assembly includes a positioning frame 6, a slide groove 7, a slider 8, a check portion, a contact portion and a positioning portion. Positioning frames 6 are fixedly installed on both sides of the clamping ring 3, and slide grooves 7 are provided at both ends of the two positioning frames 6. A slider 8 is slidably installed on each slide groove 7, and a check portion is installed between the two sliders 8 on each positioning frame 6. The contact portion is installed inside the check portion for contacting the cable, and the positioning portion is installed on the check portion for fixing the position of the contacted portion.

[0025] Specifically, when connecting cables and wires, it is necessary to clean the terminals and cables to remove any grease, dirt and oxides that may be present according to the size of the crimping sleeve 1 and the cable, and then peel off a layer of insulation at the contact point between the crimping sleeve 1 and the cable to allow current to flow safely through the connection, and then insert the cable into the crimping sleeve 1. At this time, the contact part is moved to the working position through the setting of the positioning part, and the position of the contact part is fixed. At this time, the contact part contacts the cable, and as the cable continues to enter the crimping sleeve 1, the contact part moves accordingly. The cable can be positioned by setting the check part. When the end of the cable contacts the bottom of the crimping sleeve 1, the position of the cable can be fixed by setting the fixing component and the locking component.

[0026] The above, such as Figure 5 As shown, the non-return portion includes a housing 9 and a non-return pawl 10 . The housing 9 is fixedly mounted on each slider 8 , and the non-return pawl 10 is fixedly mounted inside each housing 9 .

[0027] Specifically, as the contact portion rotates, the non-return pawl 10 is provided to prevent the contact portion from reversing, thereby fixing the position of the cable.

[0028] The above, such as Figure 5 As shown, the contact portion includes a contact roller 11, anti-skid grooves 12 and a ratchet 13. A contact roller 11 is rotatably installed between the two outer shells 9 on each positioning frame 6. Each contact roller 11 is fixedly installed with multiple anti-skid grooves 12 at equal angles in a circular shape. A ratchet 13 is fixedly installed at both upper and lower ends of each contact roller 11. The ratchet 13 is located inside the outer shell 9 and meshes with the non-return pawl 10.

[0029] 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.

[0030] 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.

[0031] 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.

[0032] like Figure 6As 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.

[0033] 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.

[0034] 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.

[0035] Specifically, when installing the cable, the rotating ring 16 rotates to drive the active bevel gear 18 to rotate, and the active bevel gear 18 drives the driven bevel gear 17 to rotate, thereby driving the driven bevel gear 17 to rotate to fix the cable.

[0036] The above, such as Figure 7 As shown, the wire pressing part includes a fixed cylinder 19, a fixed nut 20, a fixed bolt 21 and a transmission rod 22. A fixed cylinder 19 is provided on each active bevel gear 18. Multiple fixed cylinders 19 are fixedly installed on the crimping sleeve 1. A fixed nut 20 is fixedly installed on the end of each fixed 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. Multiple transmission rods 22 correspond to multiple driven bevel gears 17 one by one, and the transmission rod 22 is fixedly connected to the driven bevel gear 17.

[0037] Specifically, as the driven bevel gear 17 rotates, the driven bevel gear 17 drives the transmission rod 22 to rotate, and the transmission rod 22 drives the fixing bolt 21 to rotate. The fixing bolt 21 cooperates with the fixing nut 20, and the fixing bolt 21 moves along the axial direction of the fixing bolt 21 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 reducing the influence on the cable during frequent disassembly and assembly.

[0038] like Figure 6As shown, the driving assembly is installed on the fixed frame 5, and is used to drive the fixed frame 5 to move. The driving assembly includes a worm wheel 23, a worm 24 and a joint 25. The worm wheel 23 is fixedly installed on the rotating ring 16, and the worm 24 is rotatably installed on the fixed frame 5. The worm 24 is meshed with the worm wheel 23. One end of the worm 24 is fixedly installed with a joint 25, and the joint 25 is rotatably matched with the fixed frame 5.

[0039] Specifically, when driving the rotating ring 16 to rotate, a tool such as a wrench is connected to the connection, and then the worm 24 is screwed to rotate, and the worm 24 drives the worm wheel 23 to rotate, thereby driving the rotating ring 16 to rotate.

[0040] like Fig. 9 As shown, the locking assembly is installed on the fixing frame 5 and is used to fix the driving assembly. The locking assembly includes a locking ring 26, a locking frame 27, a reset 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 frame 27 is slidably installed on the fixing frame 5. The locking frame 27 is adapted to the locking ring 26. A reset spring 28 is fixedly installed between the fixing frame 5 and the locking frame 27. The locking nut 29 is fixedly installed on the fixing frame 5. The fastening bolt 30 is threadedly installed on the locking nut 29, and the end of the fastening bolt 30 abuts against the locking frame 27.

[0041] Specifically, after fixing the relative position of the cable and the crimping sleeve, it is 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 reset 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 stability of the cable and the crimping sleeve during the cooperation due to vibration, 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 reset spring 28 returns to its original position.

[0042] To sum up, when connecting cables and wires, it is necessary to clean the terminals and cables according to the size of the crimping sleeve 1 and the cable to remove possible grease, dirt and oxides, and then peel off a layer of insulation layer at the contact point between the crimping sleeve 1 and the cable so that the current can flow safely through the connection, and then insert the cable into the crimping sleeve 1. 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 at this time. When plugging the cable, move the arc frame 15 to move the arc frame 15 out of the arc groove 14, and then hold the arc frame 15 and 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 screw the arc frame 15 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.

[0043] 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.

[0044] When the end of the cable moves to the installation position inside the crimping sleeve 1, the position of the cable needs to be fixed. At this time, a tool such as a wrench is connected to the connection, and then the worm 24 is turned to rotate. 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 active bevel gear 18 is driven to rotate, and the active bevel gear 18 drives the driven bevel gear 17 to rotate, thereby driving the driven bevel gear 17 to rotate.

[0045] As the driven bevel gear 17 rotates, the driven bevel gear 17 drives the transmission rod 22 to rotate, and the transmission rod 22 drives the fixing bolt 21 to rotate. The fixing bolt 21 cooperates with the fixing nut 20, and the fixing bolt 21 moves along the axial direction of the fixing bolt 21 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 reducing the influence on the cable during frequent disassembly and assembly.

[0046] After fixing the relative position of the cable and the crimping sleeve, it is 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 reset 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 stability of the cable and the crimping sleeve during the cooperation due to vibration, and when disassembling the crimping sleeve, after removing the fastening bolt 30, the locking frame 27 can be separated from the locking ring 26, and the reset spring 28 returns to its original position.

[0047] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
