Next, a sliding groove 22 is provided on one side of the inner wall of the groove ring block 21, and a sliding hole 23 is provided on one side inside the sliding groove 22. A plurality of clamping grooves 210 are symmetrically provided on the inner wall of the sliding hole 23. A circular ring block 26 is rotatably connected to the inner wall of the circular ring block 26. A plurality of abutment blocks 27 are fixedly connected to the inner wall of the circular ring block 26. The outer surface of the circular ring block 26 is located in the inner wall of the sliding hole 23 and is fixedly connected to a second spring 28. One end of the second spring 28 is fixedly connected to a rectangular clamping block 29. The two ends of the rectangular clamping block 29 are respectively inserted into the inner walls of the two opposite clamping grooves 210. When the end of the wire with a section of insulation removed is inserted into the interior of the terminal body 1 for installation, it can be first passed through the inner wall of the groove ring block 21, and then inserted into the interior of the terminal body 1. Then, the end of the terminal body 1 away from the groove ring block 21 is squeezed by a machine to fix the wire. At this time, the rectangular clamping block 29 is held and pulled upward, driving the second spring 28 to be stretched, and the two ends are pulled out of the clamping groove 210. Then, the circular ring block 26 is rotated to one end to a certain angle in the inner wall of the slide groove 22, driving one side of several abutting blocks 27 to abut and push the limit rod 24 to the center position of the groove ring block 21. The first spring 25 is compressed, and one end of the limiting rod 24 is inserted into the outer surface insulation of the wire to fix it in the secondary limit position. At this time, the rectangular clamping block 29 is released, so that it is clamped into the corresponding clamping groove 210 under the reset and limit of the second spring 28, and the circular ring block 26 with the adjusted angle is limited and fixed, so that the limiting rod 24 is fixed in position after the wire is limited for the second time. In this way, if it is used improperly or the pulling force is too large, it will not easily cause the connection between the terminal body 1 and the wire to be unstable, loose and fall off, thereby avoiding affecting the use of the wire.

[0029] Reference Figure 2-4As shown, this embodiment discloses a rectangular groove 211 on one side of the rectangular block 29, which is arranged at one end of the rectangular block 29 away from the second spring 28. The rectangular groove 211 makes it convenient to manually buckle one end of the rectangular block 29, making it easier to pull it. A slide bar 212 is fixedly connected to one side of the rectangular block 29, and a circular groove 213 is formed on the outer surface of the circular ring block 26 at the inner wall of the second spring 28. The slide bar 212 is slidably connected to the circular groove 213, and the slide bar 212 is sleeved and connected to the second spring 28. By providing the slide bar 212 and the circular groove 213, the inner wall of the second spring 28 can be supported and reinforced, and the rectangular block 29 can be limited at the same time, so that it is more firmly and stably limited to the groove ring block 21 rotated to a certain angle.

[0030] Reference Figure 2-4 As shown, this embodiment discloses that the inner wall of one end of the limiting rod 24 is rotatably connected to a roller 214, and the roller 214 rolls and abuts against the abutment block 27. By providing the roller 214, the contact wear between one end of the limiting rod 24 and the abutment block 27 can be reduced, making it easier for the abutment block 27 to push the limiting rod 24 to move, thereby improving the service life of both. The longitudinal cross-section of one end of the limiting rod 24 is conical, and the conical end of the limiting rod 24 is arranged at the end away from the roller 214. By providing one end of the limiting rod 24 with a conical shape, after the limiting rod 24 is abutted and inserted on the wire, one end can abut and be stuck in the insulation skin on the outer surface of the wire, making its clamping more firm and stable.

[0031] Reference Figure 5 As shown, this embodiment discloses that the protective device 3 includes a protective sleeve 32, and elastic blocks 33 are fixedly connected on both sides of one end of the protective sleeve 32. The inner wall of one end of the protective sleeve 32 is sleeved on the outer surface of one end of the groove ring block 21. The outer surface of the groove ring block 21 is symmetrically fixedly connected with a U-shaped block 31, and the elastic block 33 is inserted into the inner wall of the U-shaped block 31. Before inserting the wire into the interior of the terminal body 1, manually put the protective sleeve 32 on the outer surface of the wire, and then insert one end of the wire into the groove ring block 21 and the inner wall of the terminal body 1. After fixing it, slide the protective sleeve 32 to one end on the outer surface of the wire to a certain position, and put one end on the outer surface of the groove ring block 21, seal the high column on one side, and then make the elastic card block 33 fixed on the outer surface of one end be stuck into the inner wall of the U-shaped block 31 on the groove ring block 21, and fix the protective sleeve 32 on the groove ring block 21. In this way, the interface of the connecting wire can be supported and protected to avoid bending and breaking during use. At the same time, the components inside the groove ring block 21 are also protected to avoid corrosion damage caused by exposure to air, thereby improving the service life of the terminal body 1 and the wire.

[0032] Reference Figure 5As shown, this embodiment discloses that a plurality of rubber strips 34 are fixedly connected to the inner wall of one end of the protective sleeve 32, and the plurality of rubber strips 34 are arranged at equal distances. By providing the rubber strips 34, the contact friction force of the inner wall of one end of the protective sleeve 32 can be increased. When the wire is passed through the protective sleeve 32 and fixed in the terminal body 1 and the limiting device 2, the wire is not easy to shake in the inner wall of the protective sleeve 32, and the limiting protection at the connection port can be more firm and stable. A limiting block 35 is symmetrically fixedly connected to one side of the U-shaped block 31, and the limiting block 35 is fixed on both sides of the entrance of the U-shaped block 31 in an inclined manner. By providing the limiting block 35, the area of ​​the entrance of the U-shaped block 31 can be increased, so that the elastic card block 33 can be quickly aligned and inserted.

[0033] Working principle: when the end of the wire with a section of insulation removed is inserted into the interior of the terminal body 1 for installation, it can be passed through the inner wall of the groove ring block 21 first, and then inserted into the interior of the terminal body 1. Then, the end of the terminal body 1 away from the groove ring block 21 is squeezed by the machine to fix the wire. At this time, the rectangular clamping block 29 is held and pulled upward, so that the slide bar 212 on one side slides upward in the inner wall of the circular groove 213, driving the second spring 28 to be stretched, and the two ends are pulled out of the clamping groove 210. Then, it is rotated to one end to drive the circular ring block 26 to rotate to a certain angle in the inner wall of the slide groove 22, driving one side of several abutting blocks 27 to abut. Then push the limit rod 24 to move toward the center position of the groove ring block 21, so that its first spring 25 is compressed, and one end of the limit rod 24 is inserted into the outer surface insulation of the wire to fix it for the second limit. At this time, release the rectangular clamping block 29, so that it is clamped into the corresponding clamping groove 210 under the reset and limit of the second spring 28, and the circular ring block 26 with the adjusted angle is limited and fixed, so that the limit rod 24 is fixed in position after the wire is limited for the second time. In this way, if it is used improperly or the pulling force is too large, it will not easily cause the connection between the terminal body 1 and the wire to become unstable, loosen and fall off, thereby avoiding affecting the use of the wire.

[0034] Before inserting the wire into the interior of the terminal body 1, manually put the protective sleeve 32 on the outer surface of the wire, and then insert one end of the wire into the groove ring block 21 and the inner wall of the terminal body 1. After fixing it, slide the protective sleeve 32 to one end on the outer surface of the wire to a certain position, and put one end on the outer surface of the groove ring block 21, seal the high column on one side, and then make the elastic card block 33 fixed on the outer surface of one end be stuck into the inner wall of the U-shaped block 31 on the groove ring block 21, and fix the protective sleeve 32 on the groove ring block 21. In this way, the interface of the connecting wire can be supported and protected to avoid bending and breaking during use. At the same time, the components inside the groove ring block 21 are also protected to avoid corrosion damage caused by exposure to air, thereby improving the service life of the terminal body 1 and the wire.
