3. The quick connector based on the switch cabinet cable according to claim 2, wherein the notch rounding assembly (4912) comprises a clamping groove (49121) formed in the base ring (494), the bottom end of the clamping groove (49121) penetrates through the convex tooth (493), and the clamping groove (49121) is in sliding connection with a non-return bolt (49122);
The top surface of the base ring (494) is provided with a non-return spring sheet (49123) matched with the non-return bolt (49122).
4. The quick connector based on the switch cabinet cable according to claim 1, wherein a spline hole is formed in the end, close to the outside, of the rotating shaft (42).
5. The quick connector based on a switchgear cable according to claim 2, characterized in that the inside of the through hole (491) is fixedly connected with an auxiliary ring cooperating with the metal sheet (496).
6. The quick connector of claim 2, wherein the knob (492) is provided with a screw hole matched with the stud (497), and the thread of the screw hole is positioned at the middle lower part.
7. The quick connector based on the switch cabinet cable according to claim 3, wherein the top surface of the knob (492) is provided with a prying opening matched with the clamping groove (49121) and the non-return bolt (49122).
8. The method of using a switchgear-cable-based quick connector according to claim 1, comprising the steps of:
S1, selecting a connection position on a cable (1), attaching a rectangular seat (2) to the surface of the cable, covering calipers (3) on two sides of the cable (1) at the moment, rotating a rotating shaft (42) to enable a worm (46) to push a gear (44) to rotate along a worm wheel (45), and enabling the gears (44) on two sides to pull the calipers (3) on two sides to perform relative movement, wherein the rectangular seat (2) can be locked on the cable (1);
S2, after the rectangular seat (2) is installed along the cable (1), a screw bolt (497) is rotated by a screw driver, so that the screw bolt (497) is synchronously driven to rotate in the process of downwards moving along the knob (492), the convex teeth (493) at the bottom of the knob (492) are rotated out of the notch through circular motion and push the metal sheet (496) to downwards move along the base ring (494) until a conical head formed by the metal sheet (496) penetrates through the outer skin of the cable (1), and the screw bolt (497) downwards moved in the process presses the movable plates (499) to ensure that each movable plate (499) gradually contacts with the stressed edges (498) at different positions from bottom to top, so that the metal sheet (496) penetrating through the skin of the cable (1) is upwards bent along the outer side and then penetrates out of the skin of the cable (1) again to curl;
S3, after the convex teeth (493) extrude the base ring (494) and rotate to the top surface of the base ring, the convex teeth (493) cross the non-return spring plate (49123), the non-return bolts (49122) on the convex teeth (493) are in butt locking with the non-return spring plate (49123), the knob (492) is rotated when the moment seat (2) is disassembled, at the moment, the convex teeth (493) push the base ring (494) to rotate along the non-return spring plate (49123) by using the non-return bolts (49122), and the metal sheet (496) which moves synchronously with the base ring (494) cuts the broken cable (1) skin by using the side edge of the metal sheet, so that the broken part forms a circular notch.
