A method for electrically connecting two electrical lines. Each electrical line contains at least two electrical conductors that are insulated from each other, and one common sheath surrounding the electrical conductors. One of the two lines (2) is equipped with insulated conductors and is flexible, while the other line (1) has a stiff, tubular metal sheath. To produce a moisture-proof connection between the conductors of the electrical lines, first the sheath is removed from a section of the conductors of the flexible line (1) and insulation is removed from the conductors so that the ends are bared. The conductors prepared in this manner are placed in a flexible rubber seal (10) containing passage holes to separate the conductors. After that, the conductors of the flexible line (1) are electrically connected to the conductors of the other line (2) which protrude from the metal sheath. A metal tube (13) is then positioned over the entire connection area. Finally, one end of the tube (13) is securely connected to the metal sheath and the other end is compressed around the around the seal (10).

Method for electrically and conductively connecting two electrical lines

A device for attaching protective insulation to the end of an electric wire, having at least one lead to which a contact element has been attached, includes a carrier (1), equipped with at least three injection dies (3), which can rotate around an axis (A), and of at least one injection molding device (2, 10), located in the circumferential area of the carrier (1). A guide path, extending circumferentially around the carrier (1), is attached to a fixed part of the device. The guide path includes two portions of different radii, extending together nearly 360.degree., which are concentric to the axis (A) of carrier (1), and converge at one end through a transition piece in the guide path. The other ends of the guide path are located at the loading position level (I) of the injection dies (3). The movement of the injection dies (3) is guided by the guide path. The injection dies are closed in the small radius area of the guide path, and are open in the larger radius area. The carrier (1) can rotate in steps of an angle corresponding to the distance of the injection dies (3) from each other.

Device for attaching a protective cover to the end of an electric wire

A device for attaching an electrical plug connector to the end of an electrical line containing at least one core is presented. In this device, the line is transported with a cyclic advance through processing stations in which the core of the line is stripped of insulation and a contact element is applied to the conductor exposed in this manner. To produce an extruded protective body for the contact element, with maintenance of the cycle of the device, an injection molding unit is provided with a carrier (17) and at least one extruder (18, 22). The carrier is equipped with at least three injection molds (19) and is rotatable about an axis (A). The injection molds 19 are provided with inlet openings (20). The injection molds are fastened to the carrier (17) whereby they are separated from each other in a circumferential direction, at an identical distance from the axis (A) of the carrier (17). The extruder (18, 22) is displaceable in the direction of the carrier (17) and is arranged with its exit opening at the level of the inlet openings (20) of the injection molds (19).
