DESCRIPTION:
BRIEF SUMMARY
PRIOR ART
The invention is based on an apparatus connecting two electrical connecting conductors to an electrical connection. In the case of an apparatus for the electrical connection of two electrical connecting conductors disclosed by DE-A1-42 03 133, two connection pins provided with a screw thread are provided on the electrical device to be connected. The connecting conductors each lead into a connection molding having an elongated eye, the center line of which follows a circular path. The connection moldings are situated opposite one another in such a way that the eyes are diametrically opposite one another, referring to a geometrical center point between the connection pins. The connection moldings are held together by a web in such a way that the moldings having an extension piece following the connecting conductor are parallel to one another. In order to produce the connection, the eyes of the moldings are slipped over the connection pins, it being possible to alter the angle at which the connecting conductors extend with respect to the electrical device in the context of the length of the eyes, and a fixed contact with the electrical device being produced thereafter by fixing using securing screws. Such a device can be used to produce small changes in position of the connecting conductors with respect to the electrical device. The intention here is to be able to keep the line lengths shorter.
In addition to the disadvantage that two connection pins have to be present, to each of which the connecting conductors have to be fixed separately, the known device also has the disadvantage that, nevertheless, it is possible to change the position of the connecting conductors only in a narrowly limited scope, this being due to the possibilities of providing eyes in the form of part-circle recesses. The result is a high assembly outlay.
Advantages of the Invention
In contrast, the apparatus has the advantage that the connecting conductors can lead away from the electrical device in any desired angular position in a radial plane adjoining the securing pin. In this case, only a single securing pin is advantageously provided.
In an advantageous development, the selected angular positions can be reliably maintained by positive locking. In this case, a corresponding fine subdivision of the recurring forms of the positive locking surfaces enables a precise alignment of the connecting conductors to the electrical device to be produced in very small angular increments. At the same time that the connection piece carrying the connecting conductors is secured, the contact is also effected in a simple manner. In this case, a large contact-making area is provided and reliable mutual electrical isolation of the connecting conductors is achieved. In a readily manageable manner, the connection contacts and the ends of the connecting conductors are fixed in a manner encapsulated within the connection piece, access to the live parts and the screwing parts being prevented, accordance with the aid of a stopper after the connection piece has been fixed and after contact has been made between the connecting conductors and the electrical connections of the device. This results in a reliable encapsulation of the voltage-carrying parts to protect against external influences and, given appropriate safeguarding of the stopper, also in protection against unauthorized access. Overall, the apparatus has the advantage that the connection of the connecting conductors to the electrical device can be carried out with the aid of automatic assembly machines. Furthermore, the essential advantage results that, in the case of device parts that are located around the electrical connection and would hinder cable routing, an optimum point for feeding the connecting conductors can be found with the aid of the angular adjustment of the position of said connecting conductors. This results in a space-saving arrangement which also reduces the length of the connecting conductors. Such connections are also suitable, in particular, for the harsh operati
