Description

Electric crimper

technical field

The utility model relates to an electric crimping device used for crimping wire noses.

Background technique

Generally, when the wire is connected to the terminal, if it is a single-strand wire of ^10mm2 or less, it is necessary to bend a circle at the end of the wire and connect it to the terminal. And if it is a multi-strand copper wire ^above 10 mm2, it needs to be equipped with a terminal lug, and then connected to the terminal. After the multi-strand copper wire is inserted into the connecting barrel at the end of the wire lug, in order to make the fixing of the copper wire more stable, the connecting barrel needs to be crimped so that the connecting barrel is tightly attached to the copper wire.

At present, manual crimping or crimping with a fixed crimping machine are mainly used for crimping.
