[0025] In specific implementation, the shell structure of the self-locking quick connector body 1 includes: a quick connector self-locking outer shell 11, a first insulating outer shell 12 and a second insulating outer shell 15. The second insulating outer shell 15 covers the outside of the first insulating outer shell 12. A locking nut 16 is installed between the quick connector self-locking outer shell 11 and the first insulating outer shell 12, thereby forming an accommodating space inside the quick connector self-locking outer shell 11 and the first insulating outer shell 12.

[0026] Furthermore, a quick-connect connector terminal 13 is provided in the accommodating space of the quick-connect connector self-locking housing 11, and a pin bracket 14 is installed in the accommodating space of the first insulating housing 12, with one end of the pin bracket 14 connected to the quick-connect connector terminal 13.

[0027] Preferably, one end of the quick-connect terminal 13 is detachably fitted with a quick-connect terminal cap 131.

When it is necessary to rotate again, the limiting groove 242 and the limiting boss 142 need to be separated to overcome the spring force to realize the relative rotation of the adapter terminal connector 2. The rotation positioning and locking can be realized by pressing the limiting spring 5 again.

[0036] Preferably, the angle range of the adapter terminal 2 rotating relative to the self-locking quick-connect body 1 with the pin 3 as the pivot is 0-90°.
