DESCRIPTION:

BRIEF SUMMARY
STATE OF TECHNOLOGY

The invention is based on a multiway connector of the type described hereinafter. A device is known from DE-OS 37 30 571, in which the fuel injection valves are positioned in individual locating apertures of a fuel distributor piece and which are jointly contacted, electrically, by means of a multiway connector. A number of plugs, corresponding to the number of fuel injection valves, in which are fixed first electrically conducting contact elements which are connectable with second electrically conducting contact elements of the fuel injection valves, are arranged together on the multiway connector. The electrical conductors which connect the electrical connection plug of the multiway connector with the first electrically conducting contact elements, are arranged within the multiway connector. The one-piece design of the multiway connector has the disadvantage that mounting the flexible assembly, which consists of the first electrically conducting contact elements and the electrical conductors, on the multiway connector, e.g. by encapsulating it in the multiway connector which is made of plastic material, is a very elaborate and difficult process. If moreover a large number of electrical conductors is required, namely when the electrically energizable units which are contacted by the common multiway connector are to be energized at different instants rather than simultaneously, then it is particularly laborious and complicated to mount the flexible assembly.
A secure and reliable connection of the first electrically conducting contact elements and the electrical conductors with the multiway connector is not always ensured. In addition, there is the risk of damage to the first electrically conducting contact elements, the electrical conductors, and the connections between the electrical conductors and the electrically conducting contact elements.


ADVANTAGES OF THE INVENTION

In contrast, the multiway connector in accordance with the invention has the advantage of a simple and economic manufacture. The configuration of the two-piece multiway connector by way of a support part and a cover part, facilitates the straightforward arrangement of the electrical conductor on the support part, thereby not only substantially reducing the mounting effort, but also improving the access to the electrical conductors, the first electrically conducting contact elements and the plugs. The risk of damage to the first electrically conducting contact elements, the electrical conductors, and the connections between the electrical conductors and the first electrically conducting contact elements, is significantly reduced by virtue of the simplified handling and mounting.
Advantageous developments and improvements of the multiway connector specified herein are made possible by the measures listed.
It is of advantage, if the plug connections can float in the horizontal and vertical directions with the support part, so that compensation of the shape and position tolerances between the jointly contacted electrically energizable units and the multiway connector is made possible.
It is of particular advantage for the compensation of the shape and position tolerances between the electrically energizable units and the multiway connector, if the support part has fixing domes along a support axis, the number of which corresponds to the number of plugs, with which the plugs are floatably connected in the direction of a dome longitudinal axis and vertical to the same.
In this arrangement, it is of advantage, if every fixing dome has at least one transverse groove which extends in the direction of the dome longitudinal axis which is open towards a dome front face provided on the free dome end and towards the dome circumference, this groove permitting an elastic compression of the free dome end in radial direction when the plug is pushed onto the fixing dome, so that a snap-in nose provided on the plug or on the fixing dome can engage with a locating groove provided on the plug or on the fixing dome, such that the plug i
