A crimping block is arranged on one side of the connecting block. A limiting plate is arranged on the inner wall of the middle part of the terminal tube. A threaded sleeve is arranged on the outer surface of one end of the terminal tube. The outer surface of the middle part of the threaded sleeve is threadedly connected to the inner wall of the middle part of the pushing ring.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 , an intermediate bare terminal convenient for crimping in this embodiment includes a terminal tube 1. A first limiting groove 2 penetrating through the inside and outside is formed on the outer surface of one end of the terminal tube 1. The inner wall of the middle part of the first limiting groove 2 is slidably connected to the outer surface of the middle part of the connecting block 3. A crimping block 4 is arranged on one side of the connecting block 3. A limiting plate 16 is arranged on the inner wall of the middle part of the terminal tube 1. A threaded sleeve 5 is arranged on the outer surface of one end of the terminal tube 1. The outer surface of the middle part of the threaded sleeve 5 is threadedly connected to the inner wall of the middle part of the pushing ring 6. A connecting ring 7 is arranged on one side of the pushing ring 6.

[0034] Please refer to Figure 4 and Figure 7 , a sliding groove 12 is formed in the middle of the connecting block 3. The sliding groove 12 is inclined. The inner wall of the middle part of the sliding groove 12 is slidably connected to the outer surface of the middle part of the sliding rod 10. A connecting plate 9 is arranged on one side of the outer surface of the middle part of the sliding rod 10. Due to the inclined arrangement of the sliding groove 12, when the sliding rod 10 moves horizontally, the sliding rod 10 will push the connecting block 3 to move up and down by sliding in the sliding groove 12, adjusting the position of the connecting block 3 in the terminal tube 1.

[0035] Please refer to Figure 4 and Figure 7 , the sliding groove 12 communicates with the operation groove 11. The operation groove 11 is arranged on one side of the connecting block 3. The operation groove 11 extends from the side of the connecting block 3 outside the terminal tube 1 to the sliding groove 12. The inner wall of the middle part of the operation groove 11 is slidably connected to the outer surface of the middle part of the connecting plate 9. The arrangement of the operation groove 11 can provide a moving space for the connecting plate 9, enabling the connecting plate 9 to smoothly drive the sliding rod 10 to slide in the sliding groove 12. At the same time, the stability of the movement of the connecting plate 9 can be improved through the operation groove 11.

[0036] Please refer to Figure 2 and Figure 6 , the crimping block 4 is arranged on the side of the connecting block 3 inside the terminal tube 1. The cross-section of one end of the crimping block 4 is triangular. Due to the triangular cross-section of one end of the crimping block 4, the tip of the crimping block 4 can break through the insulating layer of the wire and crimp with the wire core.

[0037] Please refer to Figure 3 and Figure 5, a second limiting groove 17 penetrating through the inner and outer surfaces is formed on the outer surface of the middle part of the threaded sleeve 5, and the inner wall of the second limiting groove 17 is slidably connected to the outer surface of the middle part of the connecting block 3. The setting of the second limiting groove 17 can improve the stability of the connecting block 3 during movement and provide space for the movement of the connecting plate 9 at the same time.

[0038] Please refer to Figure 3 and Figure 4 , a slider 8 is slidably arranged on the inner wall of the connecting ring 7. One end of the slider 8 is arranged in a stepped shape, and the other end of the slider 8 is arranged on one side of the connecting plate 9. The stepped setting of one end of the slider 8 enables the slider 8 to be better connected to the connecting ring 7, so that the connecting ring 7 can drive the slider 8 to move more stably when rotating, and the slider 8 can drive the connecting plate 9 to move.

[0039] Please refer to Figure 1 and Figure 4 , there are two pushing rings 6. The inner walls of the middle parts of the two pushing rings 6 are respectively threadedly connected to the outer surfaces of the middle parts of the two threaded sleeves 5. The two threaded sleeves 5 are respectively arranged on the outer surfaces of both ends of the terminal tube 1. By the cooperation of the two pushing rings 6 and the two threaded sleeves 5, the crimping of the two wires at both ends of the terminal tube can be controlled.

[0040] Please refer to Figure 3 and Figure 6 , on one side of the inner wall of the middle part of the terminal tube 1, a conductive plate 15 is arranged. On one side of the conductive plate 15, a conductive spring piece 14 is arranged. The conductive spring piece 14 is slidably connected to the outer surface of one side of the conductive terminal 13. The conductive terminal 13 is arranged at one end of the connecting block 3. Through the setting of the conductive spring piece 14, when the conductive terminal 13 moves along with the connecting block 3, the conductive terminal 13 will move between the corresponding two conductive spring pieces 14, so that the conductive spring piece 14 is tightly connected to the conductive terminal 13. Through the cooperation of the crimping block 4, the connecting block 3, the conductive terminal 13, the conductive spring piece 14, the conductive plate 15 and the terminal tube 1, the two wires at both ends of the terminal tube 1 are conducted.

[0041] For an intermediate bare terminal that is convenient for crimping in this embodiment, by rotating the pushing ring 6, the pushing ring 6 drives the connecting ring 7 to move through the threaded sleeve 5, and further the connecting plate 9 drives the sliding rod 10 to slide in the sliding groove 12, so that the connecting block 3 drives the crimping block 4 to crimp on the wire in the terminal tube 1, achieving the effect of crimping the terminal tube and the wire together without using a special crimping tool, with a relatively simple operation method and convenient use.

[0042] The working principle of the above embodiments is as follows: Insert the wire to be connected into one end of the terminal tube 1, with the conductive end abutting against one side of the limiting plate 16. Rotate the pushing ring 6, so that the pushing ring 6 moves through the threaded sleeve 5, driving the connecting ring 7 to move towards the center of the terminal tube 1. The slider 8 drives the sliding rod 10 to move through the connecting plate 9, and the sliding rod 10 slides in the sliding groove 12, driving the connecting block 3 to move towards the inner wall of the middle part of the terminal tube 1, making the tip of the crimping block 4 move towards the wire. When the connecting block 3 moves, it drives the wire terminal 13 to move between the corresponding two wire reeds 14. The wire terminal 13 pushes the wire reeds 14, causing the wire reeds 14 to swing, and thus enabling the wire terminal 13 to smoothly move between the corresponding two wire reeds 14. The two wire reeds 14 are closely attached to both sides of the wire terminal 13. When the crimping block 4 moves, the tip of the crimping block 4 will pierce the outer insulation layer of the wire and contact the wire core. The crimping block 4 continues to move, and the wire is tightly pressed through the cooperation of multiple crimping blocks 4.
