DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Example:

[0033] like Figure 1-9 As shown, this embodiment provides a quick-insert self-locking connector, comprising a connecting male head 20, on which a connecting female head 10 is provided;

[0034] The male connector 20 is provided with a male connector sleeve 21, and an elastic snap-fit ​​assembly 30 is provided inside the male connector sleeve 21. The female connector 10 is provided with a female connector sleeve 11, and the female connector sleeve 11 is provided with a connecting inner wall 17. The female connector sleeve 11 is adapted to the male connector sleeve 21, and the female connector sleeve 11 extends into the inner cavity of the male connector sleeve 21, so that the elastic snap-fit ​​assembly 30 contacts the connecting inner wall 17 for snap-fit ​​positioning.

[0035] In this embodiment, when the male connector 20 and the female connector 10 are plugged into each other, the male connector 20 is aligned with the female connector 10 so that the male connector sleeve 21 is aligned with the female connector sleeve 11. The male connector 20 is manually pushed toward the female connector 10 so that the female connector sleeve 11 is placed in the male connector sleeve 21, thereby making the elastic snap-fit ​​assembly 30 contact the inner wall 17 of the connection, and the connection is completed by snapping and positioning the elastic snap-fit ​​assembly 30;

[0036] Of course, when the male connector 20 needs to be separated from the female connector 10, it is only necessary to pull the male connector 20 so that the male connector 20 is separated from the female connector 10;

[0037] By setting the connecting male head 20 and the connecting female head 10, as well as the elastic snap-in assembly 30 in the male connecting sleeve 21 and the female connecting sleeve 11, a quick plug-in connection can be achieved, ensuring the stability and safety of the connection. The connection can be completed by a simple alignment and pushing operation. Compared with connecting the connecting male head 20 and the connecting female head 10 through a threaded sleeve, the connection can be completed by a simple alignment and pushing operation, which greatly improves the overall practicality.

[0038] Specifically, the elastic clamping assembly 30 includes a clamping sleeve 31, and the clamping sleeve 31 is arranged in the inner cavity of the male connecting sleeve 21;

[0039] An elastic sleeve 33 is provided on the clamping sleeve 31 , and a clamping protruding ring 34 is provided at the end of the elastic sleeve 33 . Multiple groups of deformation grooves 32 are evenly formed on the elastic sleeve 33 and the clamping protruding ring 34 .

[0040] In this embodiment, the elastic sleeve 33 is elastic and can be deformed inwardly through the deformation groove 32 so as to be snapped into the female connecting sleeve 11. After the snapping is completed, the elastic sleeve 33 returns to its original shape and is locked.

[0041] Specifically, a connecting protrusion ring 16 is provided on the connecting inner wall 17 , and the female connecting sleeve 11 extends into the male connecting sleeve 21 , so that the snap-fitting protrusion ring 34 is positioned on the connecting inner wall 17 through the connecting protrusion ring 16 .

[0042] Specifically, an annular contact surface 13 is further provided on the connecting inner wall 17 , and a clamping groove 14 is provided between the annular contact surface 13 and the connecting protruding ring 16 ;

[0043] A contact sleeve 25 is further disposed in the male connector sleeve 21 , and the engaging protruding ring 34 is disposed in the engaging groove 14 , so that the contact sleeve 25 contacts the annular contact surface 13 .

[0044] In this embodiment, when the female connector sleeve 11 is placed in the male connector sleeve 21, the snap-fitting protrusion ring 34 is placed in the snap-fitting groove 14 through the connecting protrusion ring 16. The snap-fitting protrusion ring 34 cooperates with the connecting protrusion ring 16 to connect the male connector 20 and the female connector 10.

[0045] Of course, when the male connector 20 and the female connector 10 need to be separated, it is only necessary to pull the male connector 20 so that the snap-fitting protrusion ring 34 contracts and moves inward, so that the snap-fitting protrusion ring 34 moves on the connecting protrusion ring 16, thereby facilitating the snap-fitting protrusion ring 34 to be separated from the snap-fitting groove 14, and the separation process is completed;

[0046] The above-mentioned snap-in connection method can facilitate quick connection of the male connector 20 and the female connector 10 .

[0047] Specifically, a positioning guide portion 12 is provided on the outer wall of the female connecting sleeve 11 , and the positioning guide portion 12 is in close contact with the inner wall of the male connecting sleeve 21 .

[0048] In this embodiment, when the female connecting sleeve 11 is placed in the male connecting sleeve 21, the positioning guide portion 12 is in close contact with the inner wall of the male connecting sleeve 21. When the connecting male connector 20 is pushed, the positioning guide portion 12 can enable the connecting male connector 20 to maintain alignment with the connecting female connector 10 during the displacement process, so that the connecting male connector 20 and the connecting female connector 10 are stably connected.

[0049] Specifically, two groups of guide slopes 121 are symmetrically provided on the positioning guide part 12, and a mounting slope 23 is provided on the male connecting sleeve 21. The guide slopes 121 contact the mounting slope 23 to guide the positioning guide part 12 into the inner cavity of the male connecting sleeve 21.

[0050] In this embodiment, the provision of the guiding inclined surface 121 and the installation inclined surface 23 can facilitate the positioning guide portion 12 to quickly enter the male connecting sleeve 21 .

[0051] Specifically, two groups of raised inclined surfaces 15 are symmetrically provided on the connecting raised ring 16 , and the engaging raised ring 34 contacts the raised inclined surfaces 15 to guide the engaging raised ring 34 into the engaging groove 14 .

[0052] Specifically, the snap-in protrusion ring 34 is provided with a snap-in arc surface 36 , and the snap-in protrusion ring 34 is also provided with a snap-in inclined surface 35 . The snap-in inclined surface 35 and the snap-in arc surface 36 are symmetrically arranged, and the snap-in arc surface 36 is arranged at the end away from the snap-in sleeve 31 .

[0053] In this embodiment, the engagement arcuate surface 36 cooperates with the raised inclined surface 15 to facilitate the inward contraction of the elastic sleeve 33 when the male connector 20 is pushed, so that the engagement raised ring 34 engages with the engagement groove 14.

[0054] By cooperating with the provided engaging inclined surface 35 and the raised inclined surface 15 , when the connecting male connector 20 is pulled, the elastic sleeve 33 can be easily contracted inwardly, so that the engaging raised ring 34 can be disengaged from the engaging groove 14 .

[0055] Specifically, the male connector sleeve 21 is provided with a connecting pin 24, and the female connector sleeve 11 is provided with a connecting jack 111, and the connecting pin 24 is adapted to the connecting jack 111;

[0056] The outer wall of the male connector sleeve 21 is further provided with a plurality of anti-slip grooves 22 .

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the appended claims and their equivalents.
