the connector is locked, the cable (4) is inserted from the outside to the inside from the threading hole (11) on the same side with the reset groove (12), the cable penetrates through a region between the electric conductor (3) and the elastic sheet (2) in the wire locking cavity (14), then the head of the cable (4) pushes the unlocking surface (253) of the lock catch structure (25), the unlocking surface (253) swings along the pushing direction under stress, the wire pressing arm (21) of the elastic sheet (2) slips from the clamping tongue (252), the wire pressing arm (21) presses the cable (4) in a pressing mode, the cable (4) is locked on the electric conductor (3), the tight connection between the cable (4) and the electric conductor (3) is achieved, and the elastic sheet (2) pushes the push block (5) to recover to the initial position.
6. The method for locking the connector with the quick locking structure according to claim 5, wherein:
in the unlocking process of the connector, the push block (5) is pushed from outside to inside from the reset groove (12), so that after a locking buckle (53) arranged at the end part of the push block (5) penetrates through a through groove (211) on the elastic sheet (2), the push block (5) is continuously pushed from outside to inside, and the locking buckle (53) is continuously penetrated into a buckle groove (256) of the buckle structure (25) and then is buckled with the buckle groove (256) for limiting; meanwhile, the wire pressing arm (21) of the elastic sheet (2) swings and is buckled on a clamping tongue (252) on the unlocking surface (253) along the pushing direction to realize unlocking;
in the locking of connector, cable (4) from outside-in inserts from through wires hole (11) with reset groove (12) homonymy to wear to establish into the region between electric conductor (3) and shell fragment (2) in lockwire chamber (14), then cable (4) head pushes away unblock face (253) of hasp structure (25), unblock face (253) atress is swung along pushing away the direction, locking buckle (53) slippage from hasp groove (256) this moment, and line ball arm (21) of shell fragment (2) slippage from block tongue (252), line ball arm (21) support and press cable (4), and lock cable (4) on electric conductor (3), realize the zonulae occludens of cable (4) and electric conductor (3), shell fragment (2) push away ejector pad (5) and resume initial position.
