In a method for connecting an electrical conductor to an electrical contact part, wherein the contact part has deformable legs the legs are deformed by means of a bending die in such a way that the legs press the conductor with the contact part in a force-locked manner, wherein the contact part is acted upon in so that at least the legs are materially connected to each other. A device includes a bending die for connecting an electrical conductor to an electrical contact part, wherein the contact part has deformable legs and the bending die is designed to deform the legs in such a way that the legs press the conductor with the contact part in a force-locked manner, and wherein the device also includes a laser welding device designed to act on the contact part so that at least the legs are materially connected to each other.

A pyromechanical disconnecting device having an improved electric current conductor rail. The electric current conductor rail includes a center section perpendicular to the path of a disconnecting tool, and a first and second side section extending perpendicular from the center section. The electric current conductor rail further includes a first and second end piece connected respectively to the first and second side sections apart from the center section. Each of the end pieces is connected along a fold perpendicular to the center section and includes a bore for receiving a fastener to attach the electric current conductor rail to a housing.

Pyromechanical separating device with a specially shaped current conductor rail

The invention relates to a device for pyromechanical separation comprising a housing () and a conducting rail () which is arranged therein and embodied in such a way that it is separable at a separation point () by a separating tool () which is actuated by a propulsion pyrotechnical charge (). In order to protect said conducting rail against manipulations and ensure an unequivocal positioning, the conducting rail (), the propulsion charge () and the separating tool () are fixed in the housing () in an irremovable manner by a latch () which is inserted into the housing () and are nondetachably fixed thereto. Said latch () is also used as a support for the separating tool (), i.e. it comprises a cutting edge () along which said separating tool () cuts.

According to known methods, several circuit board pieces in a three-dimensional arrangement of an electronic module are connected together electrically by the film connectors and arranged around an operator control or actuator element in the three-dimensional form. The assembly of such modules is, however, very costly because the circuit boards must all be fastened mechanically. By using film connectors with greater stiffness, circuit board pieces can be held over these directly without additional mechanical securing devices and the three-dimensional circuit board arrangement can be secured by appropriate securing devices in the three-dimensional form. A preferred application is for electronic modules with operator control and/or actuator elements where the space available is very limited, in particular for modules fitted in motor vehicles.

The invention relates to a printed circuit board disposed on a film serving as the carrier material. A connector strip having a large number of connection pins is disposed on the printed circuit board using surface-mounting technology. Connector strips of this type are widespread in digital technology. In the case of circuits in the fields of power electronics or motor vehicle electronics, connector strips cannot be surface-mounted because of the larger cross-sections of the connections. In a printed circuit board of the type mentioned at the outset, recesses are provided in the film stiffener underneath the solder points, such that when the connection pins of the connector strip are soldered, level differences in the connection pins are compensated by the deformation of the carrier film. With this measure, tensions are compensated for the most part by the deformation of the carrier film, so that connector strips for power electronics and motor vehicle electronics applications can also be surface-mounted.
