Further advantageous developments of the present invention result from the dependent claims and the following description of preferred embodiments. This shows, partially schematized:

• 1 a line assembly with two lines and a housing according to an embodiment of the present invention;
• 2 Steps of a method for connecting the two lines using the housing to form the line assembly according to an embodiment of the present invention; and
• 3 Cuts AA, BB and CC of the 2 B) ;

2 shows a method for connecting a first line 10 and a second line 20 using a housing 30 to form a line assembly according to an embodiment of the present invention.

In a first, through the sequence of figures 2(a) -> 2(a) In the step indicated, end sections of the first and second lines are stripped, if necessary, so that stripped sections of first wires 11 or 21 and stripped sections of second wires 12 or 22 of the first or second line are exposed.

The two jacket sections 10A, 20A from which these stripped sections protrude become, as indicated by the sequence of figures 2 B) -> 2(c) indicated, inserted into a first insertion opening 31 or second insertion opening 32 of the provided housing 30, each of which has a slot (cf. 3 : 31B) and an insertion chamfer 31C, 32C. The stripped sections are guided through through openings 34 in stops 31A or 32A of the first or second insertion opening and into channels 33A, 33B in a recess 33 of the housing 30 and the seat of the jacket sections 10A, 20A through viewing windows 35 controlled. A housing web 33C, which forms one leg of each of the two channels 33A, 33B with a U-shaped cross section, separates the sections of the first cores 11, 21 from the sections of the second cores 12, 22.

Then the stripped section of the first wire 11 of the first line 10 and the stripped section of the first wire 21 of the second line 20 are twisted together, the stripped section of the second wire 12 of the first line 10 and the stripped section of the second wire 22 of the second line 20 twisted together and then bent back into the recess 33 or corresponding channels 33A, 33B ( 2(d) ) and before or after bending back, the twisted portions of the first cores 11, 21 are soldered together and the twisted portions of the second cores 12, 22 are soldered together, as in FIG 2(e) indicated by Lot L. If necessary, excess lengths of the sections are shortened before and/or after twisting, bending back and/or soldering.

In one through the figure sequence 2(e) -> 2(f) indicated step, the recess 33 is filled with cement Z. Provision can also be made for cement to be filled in the area of the viewing window 35 in order to better protect the veins there by means of the cement filling which is produced in this way.

Then, as through the figure sequence 2(f) -> 1 indicated, the housing 30 is arranged on a support surface 100, an outer edge of the recess 33 is closed with a cover 40, which is spot-welded to the support surface 100 in order to fix the housing 30 on the support surface 100, and S-joints of the first and second line 10, 20 the housing 30, which are fixed with further covers 41, 42 on the bearing surface 100 by the further covers 41, 42 being spot-welded to the bearing surface 100.

Although exemplary embodiments have been explained in the preceding description, it should be pointed out that a large number of modifications are possible.

The housing 30 or its recess 33 can have one or more further channels in addition to the channels 33A, 33B and the stops 31A, 32A can have one or more further through openings for the recess or these channels in addition to the through-openings 34 . If the first and second lines have additional cores, their stripped sections can be routed analogously through one of these through-openings, twisted and soldered together and at least partially accommodated in each of these additional channels.

In addition, it should be noted that the exemplary implementations are only examples and are not intended to limit the scope, applications, or construction in any way. Rather, the above description gives the person skilled in the art a guideline for the implementation of at least one exemplary embodiment, with various changes, in particular with regard to the function and arrangement of the components described, being able to be made without departing from the scope of protection as it emerges from the claims and these equivalent combinations of features.

Method for connecting a first at least two-wire line, in particular hard line (10), and a second at least two-wire line, in particular hard or soft line (20), using a housing (30) according to one of the preceding claims to form a line assembly according to one of the preceding claims Claims, comprising at least one of the steps: - stripping the section of the first and/or second and/or at least one additional core (11, 12, 21, 22) of the first and/or second line; - Insertion, in particular frictional clamps, of the end-side jacket section (10A, 20A) of the first and/or second line into the first or second insertion opening (31, 32), in particular passing through the sections of the first and/or second and/or at least a further wire (11, 12) of the first line through the through-openings (34) of the stop (31A) of the first insertion opening (31) and/or passing through the sections of the first and/or second and/or at least one further wire (21, 22) the second lead through the through holes (34) of the stopper (32A) of the second insertion hole (32); - Electrical connection, in particular positive and/or material connection, in particular twisting and/or soldering (L), of the sections of the first wire (11, 21) of the first and second line to one another and/or of the sections of the second wire (21, 22) the first and second line to each other and/or the sections of the at least one further core of the first and second line to each other; - Shortening and/or bending over the sections of the first and/or second and/or at least one further core (11, 12, 21, 22) of the first and/or second line; - At least partially filling the recess (33) with the filling material (Z); - At least partially covering the outer edge (33D) by the one cover (40); - forming the S-fold of the first and/or second line; and or - Cohesively connecting the one cover (40) and/or the additional cover or covers (41, 42) to the support surface (100).
