DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
It is known to connect electrical components or devices with one another by means of flexible electric conductors in order to be able to embody the proper functioning of the devices. This is true for the powering of the devices as well as for the transmission of control currents. In particular in electrical components and devices which are placed in motor vehicles and are subjected to increased jolting and vibrational stresses, it is a problem to produce a lasting, perfectly conductive connection between the conductor and the respective device. Very costly plug connections can be used for this, with which a detachable connection can be produced.
ADVANTAGES OF THE INVENTION
Because of the process according to the invention for electrically connecting two electrical components with each other, the problem of the reliable electrical connection is solved by virtue of the fact that the electrical conductors are soldered or welded to the electrical connections of the device and consequently a non-detachable connection is produced, which can also withstand high stresses. At the same time, subassemblies can also be advantageously prefabricated with regard to their electrical connection to one another via electrical conductors and in this preassembled state, can be brought into their final position inside the motor vehicle or in a fuel injection pump, for example. This simplifies the assembly outlay, reduces assembly costs, and produces a reliable, lasting, electrically conductive connection.
In an advantageous improvement, the production of the electrical connection is produced in an easy-to-assemble and reliable manner by soldering or by a welding process. After being fixed, the conductor ends, which are compressed, can be reliably and easily connected to the electrical connections via a soldering or welding process.
A securing frame is advantageously used for the preassembly of the end region of the conductors to be injection molded and fixes the position of the conductor ends so they are detachable for the time being, before the injection molding with plastic. After this fixing, the securing frame, along with the conductors disposed in it, can easily be injection molded inside an injection molding tool, with the exception of the conductor ends to be contacted. Then, the part produced by injection molding, together with the conductor ends, is advantageously conveyed to the soldering or welding process and furthermore, mechanically fixed in a reliable manner in the final position by connecting means.
A securing frame is advantageously provided for carrying out the process embodied above. The fact that it is made of two parts makes it very easy to insert and cast the conductors into the securing frame, where in a particularly advantageous manner, a right-angled deviation of the conductors from their conductor ends to the continuing cable part can also be produced. Securing elements in the securing frame or in the securing part are advantageously used for this and are embodied in the form of a groove whose cross section is adapted to the cross section of the conductor. However, only partial boundaries can also be provided, which have the advantage that in the subsequent injection molding, the conductors can be more intensively enclosed with plastic and fixed in place.
In an advantageous manner, the axial positions of the conductor ends are also fixed by securing elements of the securing frame. It is assured that the entire volume of the part produced by the injection molding is filled up to the conductors with plastic. The common intermediary piece is formed to close this volume, via which it is assured that the stripped conductor ends are excepted from the injection molding. The common intermediary piece constitutes the closure of the injection molding form (injection molding tool). Because of the compression of the conductor ends, in particular when the conductors are comprised of strands, a desired cross section can be produced, which can be polygonal, but is preferably circular.
