[0034] Embodiment 2: It can be explained on the basis of embodiment 1, such as Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, a radial limiting pin 8 is provided on the crimping male pin 2, and the limiting pin 8 passes through the middle part of the crimping male pin 2. Both ends of the limiting pin 8 protrude outward, and an inner step is provided on the inner wall of the plug shell 1. Both ends of the limiting pin 8 just press against the inner step of the plug shell 1, and then when the nut 7 is tightened, the crimping male pin 2 is just fixed.

[0035] Embodiment 3: It can be described on the basis of Embodiment 1 or Embodiment 2, such as Figure 2 , Figure 6 , Figure 8 and Fig. 9 As shown, the anti-rotation structure 4 includes a groove 41 arranged on the axial surface of the limit sleeve 3 and a mounting key 42 arranged on the axial inner wall of the plug housing 1, and the mounting key 42 is installed in the groove 41, which is conducive to quickly and conveniently fixing the limit sleeve 3 without rotating left or right. It should be noted that the groove 41 does not completely pass through the axial surface of the limit sleeve 3 (the groove 41 does not penetrate the sleeve wall of the limit sleeve 3), which is conducive to reducing the impact on the strength of the limit sleeve 3.

[0036] Embodiment 4: It can be described on the basis of Embodiment 1, Embodiment 2 or Embodiment 3, such as Figure 2 , Figure 4 , Figure 5 , Figure 7 , Figure 8 and Fig. 9As shown, the connecting mechanism 5 includes a fixing hole 51 arranged on the crimping male needle 2 and a limiting hole 52 arranged on the limiting sleeve 3. The limiting hole 52 is distributed along the axial direction of the limiting sleeve 3, and one end of the limiting hole 52 is flush with one end of the limiting sleeve 3, and the other end of the limiting hole 52 is at a distance from the other end of the limiting sleeve 3, so that the limiting hole 52 will pass through the axial direction of the limiting sleeve 3, that is, the length of the limiting hole 52 is less than the length of the limiting sleeve 3. After the fixing hole 51 overlaps with the limiting hole 52, a fixing part 53 is installed. This arrangement is advantageous In order to realize the connection between the crimping male needle 2 and the limiting sleeve 3, and prevent the relative rotation between the crimping male needle 2 and the limiting sleeve 3, the crimping male needle 2 is provided with a mounting hole 54, and correspondingly, the limiting sleeve 3 is provided with a matching hole 55, and a latch 56 is installed after the matching hole 55 overlaps with the mounting hole 54, and the latch 56 and the matching hole 55 are interference fit, which is not only conducive to realizing the fixed connection between the crimping male needle 2 and the limiting sleeve 3, but also conducive to preventing the relative rotation between the crimping male needle 2 and the limiting sleeve 3, and does not need to be disassembled during maintenance. In this embodiment, two fixing holes 51 are used, and correspondingly, two fixing members 53 are also used, and each fixing member 53 corresponds to a fixing hole 51, which is more conducive to stably preventing the crimping male needle 2 and the limiting sleeve 3 from rotating.

[0037] Embodiment 5: It can be described on the basis of Embodiment 1 or Embodiment 2 or Embodiment 3 or Embodiment 4, such as Figure 2 , Figure 4 , Figure 5 and Fig.11 As shown, the nut 7 is provided with an external thread, and correspondingly, the inner wall of the other end of the plug housing 1 is provided with an internal thread, and the internal thread and the external thread cooperate with each other to fix the nut 7 on the other end of the plug housing 1, which is convenient for installation and disassembly.
