ABSTRACT:

BACKGROUND OF THE INVENTION
The invention relates to a distributor for telecommunications installations, which has connecting elements arranged at the front in parallel rows for incoming and outgoing lines, and the connecting elements of two adjacent rows are connected to contact parts which project into the interior of the distributor.
A distributor of this type has been disclosed, for example, by DE 26 58 296 C. According to that document, the connecting elements and the contact parts of the two rows are fastened in a disk-like front part, which can be anchored in a flat rear part. The front part and the rear part together form a flat contact component. It is usual to combine contact components of this type together with disk-like wire guide elements in a carrier to form a block-like distributor module, such as has been disclosed, for example, by DE 20 48 104 C.
SUMMARY OF THE INVENTION
The invention is based on the object of reducing the production outlay for the distributor. This object is achieved by an improvement in a distributor having connecting elements arranged in parallel rows for incoming and outgoing lines, the connecting elements of two adjacent wires in each case being connected to contact parts which project into an interior of the distributor, and the connecting elements and contact parts of the two rows being fixed in a front part which is anchored in a rear part of the distributor. The improvement comprises a common rear part having a number of successive front parts and the rear part being designed to be inherently stable to form together with the attached front parts a self-supporting distributor module.
As a result of combining a number of rear parts to form a single, intrinsically stable component, an additional carrier for the contact components is no longer needed. Consequently, the installation step of inserting the contact components into the carrier part is dispensed with. It goes without saying that a rear part of this type should be produced using injection-molding technology, so that only one production step is required in order to form the holders for a large number of front parts. Injection molds of this type can be varied, by means of inserts, in such a way that the rear parts
can be provided with a different number of holders for the front parts, as required.
By means of providing slot-like channels in the rear part between the front parts, the incoming and outgoing lines can be led in the channels right up to the associated connecting elements. The additional wire guide elements are therefore dispensed with.
The development of providing the rear part with web-like strips to form compartments to anchor each of the front parts results in a simple, material-saving and compact structure of the rear part. Molding by injection molding makes it possible, without any additional outlay, to provide comb-like guide slots for the lines, as well as fastening openings, for example, in the base plate, along the edges of the latter.
The invention will be explained in more detail below using an exemplary embodiment illustrated in the drawings.
