[0027] During specific implementation, the housing structure of the self-locking quick-insert joint body 1 includes: a quick-insert joint self-locking housing 11, a first insulating housing 12, and a second insulating housing 15. The second insulating housing 15 covers the outside of the first insulating housing 12, and a locking nut 16 is installed between the quick-insert joint self-locking housing 11 and the first insulating housing 12, thereby forming an accommodating space inside the quick-insert joint self-locking housing 11 and the first insulating housing 12.

[0028] Furthermore, a quick-insert joint terminal 13 is provided in the accommodating space of the quick-insert joint self-locking housing 11, and a pin shaft bracket 14 is installed in the accommodating space of the first insulating housing 12. One end of the pin shaft bracket 14 is connected to the quick-insert joint terminal 13.

[0029] Preferably, a quick-insert joint terminal cap 131 is detachably installed at one end of the quick-insert joint terminal 13.

[0031] The housing structure of the adapter terminal joint 2 includes a terminal insulating housing 21 and a rotating insulating housing 25. The rotating insulating housing 25 can rotate relative to the terminal insulating housing 21 to rotate out a receiving space for the adapter terminal joint 2 to rotate after being quickly connected to the self-locking quick-insert joint body 1.

[0032] Further, a terminal support frame 22 is installed between the terminal insulating housing 21 and the rotating insulating housing 25.

[0036] The function of the limiting spring 5 is that when the rotation position is locked, the limiting groove 242 and the limiting boss 142 cooperate for limiting and are pressed by the limiting spring 5. When rotation is required again, it is necessary to overcome the spring force to separate the limiting groove 242 from the limiting boss 142 to realize the relative rotation of the adapter terminal joint 2, and then the rotation positioning can be locked again by the pressing of the limiting spring 5.

[0037] Preferably, the angle range for the adapter terminal joint 2 to rotate relative to the self-locking quick-insert joint body 1 with the pin shaft 3 as the rotation axis is 0 - 90°.
