[0021] See also Figures 1 to 4 A plug-in power cable connector includes a male terminal 10, a female terminal 20 and two sets of stoppers that cooperate with each other. The two sets of stoppers are respectively connected and arranged on the opposite sides of the male terminal 10 and the female terminal 20, and the two sets of stoppers are used to fix the conductive inner core inserted into the wire 60; when making an electric connection, the opposite sides of the male terminal 10 and the female terminal 20 can be plugged into each other, so that the wires 60 in the stoppers respectively connected to the male terminal 10 and the female terminal 20 can be connected to each other by mutual conduction.

[0022] In this embodiment, both the male terminal 10 and the female terminal 20 can be made of conductive metal materials, and after the two are plugged into each other, the male terminal 10 and the female terminal 20 can be conductive to each other.

[0023] In this embodiment, the limiter includes a fixing portion 30, an anti-loosening portion 40 and a blocking cap 50. The fixing portion 30 is connected to the male terminal 10 or the female terminal 20; the anti-loosening portion 40 is formed on the side of the fixing portion 30 facing away from the male terminal 10 or the female terminal 20; and the blocking cap 50 is detachably clamped and fixed on the side of the anti-loosening portion 40 facing away from the fixing portion 30. After one end of the wire 60 is peeled and the conductive inner core is exposed, it can be passed through the blocking cap 50 and the anti-loosening portion 40 in turn and extended into the fixing portion 30, and the fixing portion 30 is used to clamp and fix the conductive inner core at the end of the wire 60. The wire 60 that extends into and passes through the anti-loosening portion 40 can be coiled in the anti-loosening portion 40, so that when the wire 60 is pulled and dragged, the end of the wire 60 can be prevented from being pulled out of the fixing portion 30.

[0024] In this embodiment, the fixing portion 30 includes a terminal connection seat 31, a pressure plate 32, a threaded rod 33 and a knob 34. The terminal connection seat 31 is fixedly connected to the male terminal 10 or the female terminal 20, and the terminal connection seat 31 is also made of a conductive metal material, so that it can complete the conductive connection between the wire 60 fixed therein and the male terminal 10 or the female terminal 20.

The knob 34 is fixedly connected to the top of the threaded rod 33, so that when the knob 34 is held and rotated, the threaded rod 33 can be driven to rotate in or out. The pressure plate 32 is arranged in the inner cavity of the terminal connection seat 31, and the top of the pressure plate 32 is rotatably connected to the lower end of the threaded rod 33, so that when the threaded rod 33 is screwed in or out, its bottom end can rotate at the top of the pressure plate 32 and drive the pressure plate 32 to move longitudinally, so that the pressure plate 32 can press the conductive inner core of the wire 60 inserted into it to the bottom of the terminal connection seat 31.

[0025] In this embodiment, the anti-loosening part 40 includes an extended connection seat 41, an adjustment shaft 42, a groove 43, a winding column 44 and a threading hole 45. The extended connection seat 41 is fixedly connected to the side of the terminal connection seat 31 facing away from the male terminal 10 or the female terminal 20. The winding column 44 is rotatably arranged in the inner cavity of the extended connection seat 41, and the threading hole 45 is formed in the middle of the winding column 44, and the wire 60 can pass through the threading hole 45 and extend into the terminal connection seat 31 of the fixed part 30; there is a gap between the outer wall of the winding column 44 and the inner wall of the extended connection seat 41, and the rotation of the winding column 44 can make part of the wire 60 be coiled on the outer wall of the winding column 44. The adjustment shaft 42 is formed at the end of the winding column 44, and the adjustment shaft 42 is rotatably connected to the extended connection seat 41, so that the adjustment shaft 42 can be used to drive the winding column 44 to rotate.

The gap between the adjustment shaft 42 and the hole of the extension connection seat 41 through which it passes is small, so that the adjustment shaft 42 is not easy to be mis-deflected when it is not adjusted by the user.

[0026] When the wire 60 is pulled, the conductive core at the end of the wire 60 that is clamped and fixed under the pressure plate 32 is prevented from loosening due to the influence of the portion of the wire 60 that is coiled around the winding post 44 .

[0027] In this embodiment, the blocking cap 50 can be an elastic rubber cap, and a center hole 51 is formed in the middle of the blocking cap 50, the wire 60 can pass through the center hole 51 for connection, and the blocking cap 50 can block the opening of the extended connecting seat 41.
