Description

  The present invention relates to a crimping tool for a bare crimping terminal used when attaching a bare crimping terminal fixed to a bare wire portion by crimping to a mounting terminal such as a distribution board or a distribution board.

  A conventional crimping tool for a bare crimping terminal inserts a bare wire portion into a cylindrical part of the crimping terminal and presses the cylindrical part with a hydraulic pump or an electric switch with a pushing piece to crimp it. .

  However, there are many narrow places where distribution boards and switchboards are installed, and hold the heavy bare crimping terminal crimping tool with one hand, and operate the hydraulic pump handle or electric switch with the other hand. It had to be a laborious and time-consuming work.

  Also, when attaching crimp terminals to mounting terminals such as distribution boards and distribution boards, if the contact surface is not parallel, you must use a tool such as pliers to match the crimp terminals to the mounting terminals. Indeed, it will be a tough work, so if you use the force of the bolt screw attached to the crimping terminal and the mounting terminal forcibly, a large current will flow, which may cause heating and lead to an accident. There were drawbacks.
