Patent number: 11876330Abstract: A tool for producing an arrangement composed of an electrical line and a contact device with a crimp sleeve includes a first press jaw unit and a guide unit. The first press jaw unit delimits a tool receptacle and receives the crimp sleeve and the electrical line. The first press jaw unit has a first press jaw with a first press surface and a second press jaw with a second press surface. The second press surface is adjustable between a first press position positioned radially inwardly and a second press position. The guide unit provides a first pressing force transmitted into the first press surface and from the first press jaw to the second press jaw.

Publication number: 20210175641Abstract: A fabric-contact device includes a first contact section having a first contact face on a first upper side, a second contact section having a second contact face on an underside facing the first contact section, and a retaining device. The first contact face faces the second contact section and the first contact section is connected to the second contact section on a first side of the first contact section. The retaining device has a first retaining element connected to a second side of the first contact section at a first fixed end. The first retaining element is guided laterally past the second contact section by a first section of the first retaining element bordering the first fixed end. A second section of the first retaining element bordering the first section on a side opposite the first fixed end engages behind the second contact section and affixes the second contact section to the first contact section.Type: ApplicationFiled: February 22, 2021Publication date: June 10, 2021Applicant: TE Connectivity Germany GmbHInventors: Christopher Muth, Uwe Bluemmel, Marcel Baltes
