Patent ID: 8196288

Claim:
A double crimping tool for fastening an electrical conductor with insulation to a contact element, comprising: a first crimping unit comprising a first drive cam plate and a first plurality of crimping stamps for forming a first press section in the region of a stripped end of the electrical conductor; a second crimping unit comprising a second drive cam plate and a second plurality of crimping stamps for forming a second press section in the region of the insulation of the electrical conductor; wherein the first plurality of crimping stamps comprise a first plurality of respective anvil surfaces that are directed towards each other, wherein the second plurality of crimping stamps comprise a second plurality of respective anvil surfaces that are directed towards each other, wherein between said first plurality of respective anvil surfaces is a first receiving cross section for receiving a first set of sections of the contact element, wherein between said second plurality of respective anvil surfaces is a receiving cross section for receiving a second set of sections of the contact element, wherein said first and second sets of sections of the contact element are adapted to be pressed together with the electrical conductor, wherein the first plurality of crimping stamps are displaced by rotation of the first drive cam plate to carry out the pressing procedure by narrowing the first receiving cross section, wherein the second plurality of crimping stamps are displaced by rotation of the second drive cam plate to carry out the pressing procedure by narrowing the second receiving cross section, wherein the first drive cam plate and the second drive cam plate are connected to a common force introduction element by a first lever and a second lever, respectively, such that during the pressing procedure the first drive cam plate is rotated by a predefined initial pressing angle to reduce the first receiving cross section in the press section of the first drive cam plate, and the second drive cam plate is made to rotate only after the first drive cam plate attains the predefined initial pressing angle, in order to reduce the second receiving cross section in the press section of the second drive cam plate.
