Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of for electric connector crimping wire pull-off force detection device, it is mainly applied to the detection field of electric connector contact piece and wire crimping after crimping. BACKGROUND

[0002] Electric connector and electric connector are connected by wire, and the connection mode of wire and contact piece has two kinds: one is that wire and contact piece are welded flatly, and the other is that wire and contact piece are crimped in crimping hole. There are detailed specification instructions for crimping wire, and different diameter wires select different section crimping pliers, and the wire pull-off force value after crimping is also different. Before each production, crimping wire needs to be detected. At present, wire pull-off force detection is manually detected by tension meter, one end of wire is fixed on tension meter, one end is clamped by forceps, two people move towards each other, and the pulling speed and force cannot be controlled. The tension is inconsistent in height direction, and the human factor has great influence. The authenticity of data cannot be reflected, in addition, data acquisition is recorded manually, and automatic data acquisition and the change of pull-off force cannot be achieved, so the efficiency is low.

[0003] Therefore, people have been seeking a practical technical solution. CONTENT OF UTILITY MODEL
