Shearing joint tail connector

Technical Field

Currently, most of the tail-joining operations still need to be finished manually by using a knotting gun or a knotter; the tail connecting steps are as follows: operation of doubling air knotting and knot shearing;

when done using a knot gun: two wires to be connected are sent into a twisting cavity of a knotting gun, tension is slightly applied manually, a pressure trigger of the knotting gun is buckled to control pressure to knot the two wires, and finally the two wires are taken out and cut off redundant knots by scissors to finish tail connection work.

When done using a knotter: two wires to be connected are sent into a connecting and twisting cavity of a knotting gun, a machine automatically clamps two ends of the wires, a button on a knotter is pressed, the knotter knottes the two wires by utilizing pressure, and finally the two wires are taken out and cut off redundant knots by using scissors to finish tail connection work.
