[0031] like Figures 1 to 4 As shown, a connector male end 1 includes a docking shell 3 and a terminal assembly 4 arranged in the docking shell 3. The terminal assembly 4 and the connector female end 2 are plugged together to establish an electrical connection. The docking shell 3 effectively protects the internal terminal assembly 4 from external environmental factors. In this embodiment, a mounting cavity 31 is provided in the docking shell 3, and the terminal assembly 4 is movably installed in the mounting cavity 31. A rotating base 5 extending into the mounting cavity 31 is movably installed at the bottom of the docking shell 3. One end of the rotating base 5 located in the mounting cavity 31 is transmission-connected to the terminal assembly 4 and drives the terminal assembly 4 to move in the mounting cavity 31.

[0032] In this embodiment, a rotating base 5 is set at the bottom of the docking shell 3. The rotating base 5 and the docking shell 3 are movably connected and can rotate. The docking shell 3 is a hollow structure with an installation cavity 31 inside. The terminal assembly 4 is installed in the installation cavity 31; the terminal assembly 4 is transmission-connected to the rotating base 5, and when the rotating base 5 rotates, the terminal assembly 4 can be driven to move in the installation cavity 31 to achieve movement; the terminal length can be adjusted according to different usage scenarios to adapt to connector female ends 2 of different specifications, and the applicability is strong; when the connection needs to be disconnected, there is no need to unplug and unplug, and the terminal assembly 4 can be lowered to the disconnection position with the female end through the rotating base 5, which effectively prevents damage to the connector and the entry of dust and other debris to cause a short circuit.

[0033] like Figure 2 and Figure 3As shown, the rotating base 5 of this embodiment includes a rotating part 51 arranged at the bottom of the docking shell 3 and a lifting tube 52 connected to the end face of the rotating part 51 and inserted into the installation cavity 31; and the terminal assembly 4 includes a base 41 and a plurality of conductive terminals 42 inserted on the base 41. The base 41 of this embodiment is a cylindrical structure, and the conductive terminals 42 are inserted at the top of the base 41. A wiring cavity 411 for connecting cables is provided in the base 41. The wires passing through the bottom rotating part 51 and the hollow lifting tube 52 establish electrical connection with the conductive terminals 42 in the wiring cavity 411. In order to realize lifting, mutually matching threads 43 are provided on the inner wall of the base 41 and the outer wall of the lifting tube 52, and the two threads 43 are connected; in order to make rotation more convenient, a friction pattern 511 is provided on the rotating base 5. When in use, the base 41 of the terminal assembly 4 is sleeved on the lifting tube 52 of the rotating base 5 and connected thereto by thread 43. When the rotating part 51 is rotated, the lifting tube 52 will also drive the base 41 connected to the thread 43 to rise and fall along the thread 43, and then the conductive terminal 42 inserted on the base 41 will move relative to the docking shell 3, thereby controlling the length of the conductive terminal 42 exposed in the docking shell 3 and the length docking with the female end.

[0034] In order to make the base 41 and the conductive terminal 42 rise vertically along a straight line without rotating, a guide assembly is also required; Figure 2 and Figure 3 As shown, in this embodiment, four guide grooves 6 from bottom to top are arranged on the inner wall of the docking shell 3, and the guide grooves 6 are symmetrically arranged at four positions of the inner wall. Four guide ridges 7 are also arranged on the outer wall of the lifting tube 52 corresponding to each guide groove 6. In order to prevent the terminal assembly 4 from falling off when it rises to the top, a limiting portion 8 is also arranged at the top of the guide groove 6. The limiting portion 8 is arranged at the top of the docking shell 3 to block the guide groove 6 and prevent the base 41 from rising to the top and falling out. Each guide ridge 7 is aligned with the bottom guide groove 6 and inserted, and the fixed shell is sleeved on the lifting tube 52. When in use, the base 41 will rise vertically along the guide groove 6, and the existence of the limiting portion 8 can also limit the rising position of the base 41.

[0035] like Figure 4As shown, the electrical connector of another embodiment of the present application includes a connector male end 1 and a connector female end 2, and the connector male end 1 is plugged with the connector female end 2; on the outer wall of the docking shell 3 of this embodiment, a male end fixing ring 9 for fixing with the connector female end 2 is provided, and on the outer wall of the connector female end 2 and its connecting end face, a female end fixing ring 10 is provided, and the male end fixing ring 9 and the female end fixing ring 10 are both integrally formed and three screw holes for connection are respectively provided at corresponding positions thereon. When used for fixing, the male end fixing ring 9 and the female end fixing ring 10 are fixed by bolts passing through the connecting screw holes. And being in a closed state all the time can prevent dust from entering and causing poor contact. When the connection needs to be disconnected, the terminal piece can be detached from the female end connector by rotating the base 5 to achieve the disconnection effect.

[0036] The working principle of this embodiment is: this embodiment drives the lifting tube 52 fixedly connected to the end face of the rotating part 51 to rotate by rotating the rotating part 51, and then the base 41 of the terminal assembly 4 connected to the rotating tube by thread 43 will rise or fall along the fixed lifting tube 52, so as to achieve the effect of controlling the length of the terminal. After the male and female ends of the connector are inserted and connected, they are fixed by the fixing rings of the male and female ends. When plugging and unplugging are required, the terminal can be disconnected from the female end by rotating the base 5, which is convenient and quick to avoid frequent plugging and unplugging to damage the shell; and it is always in a closed state to prevent dust from entering and causing poor contact.
