The first embodiment a connection arrangement comprises the housing 1, for simplicity the explanation of the components associated with the longitudinal axis 2 is. The housing 1 has a first end face 3 and a second end face 4, that of the first end face 3 turned away. It also has two side surfaces 5, 6 the essentially parallel to each other. Furthermore it has a bottom surface 7 and in subareas a top surface 8. In the covered by the top surface 8 section are receiving chambers 9 for in connection with Figure 3 closer explained, but also in total from Figure 1 apparent connection elements provided in the form of connection sockets. The Receiving chambers 9 are several to a number in a row next to each other arranged and extend parallel to the longitudinal axis. 2 Between the first end face 3 and each receiving chamber 9 is a passage opening 13 is arranged. To the top surface 8 If a step surface 10 is offset, i. this is located closer to the bottom surface 7 than the top surface 8. From the second end face 4 go recording channels 11, each in an opening 16 of a receiving chamber 9, i. the individual recording channels 11 are in each case in accordance arranged to a receiving chamber 9. In the area of the step surface 10 is in the thus formed upwardly open Section a transverse groove 12, which is between the two Side surfaces 5, 6 and extends at right angles to the longitudinal axis of the second cuts. In the area of the transverse groove 12, however, the partitions remain between the adjacent receiving channels 11 at least exist in subareas. Furthermore, in particular from FIG. 2 recognizable that on the step surface 10 fastening hooks 14th are provided, which serve to fix the ribbon cable F, which is close to an end face corresponding recesses has, with which it hooked into the fastening hooks 14 can be. Furthermore, in the area of the side surfaces 5, 6 of the housing 1 locking hook 15 attached and that a total of four pieces, i. two each side surface 5 and 6 respectively. These serve to the lid described below 32 set. The corresponding to the first end face 3 the arrangement of the receiving chambers 9 existing passages 13 are smaller than the cross section of the receiving chambers 9. Through this can be done with the below Connection elements 17 cooperating connection elements be introduced. However, it is also possible that such connection elements be absorbed by the housing 2, for example Pin contacts have, from this on the first end face 3 of the housing 1 to project with a corresponding connector or the like to be connected has the appropriate connection sockets.

The opening 16 of the receiving chambers 9 is in the region of Quernut 12.

In each of the receiving chambers 9 is from the second end face 4, starting on the receiving channels 11 each one as a single part in Figure 3 shown connecting element 17 in the form of a Connector inserted and fixed therein.

As can be seen from FIG. 3, the connection element 17 comprises a terminal portion 18 for electrically conductive connection with the ribbon cable F and a socket portion 20, in the example, a pin contact of a corresponding Mating plug can be inserted. In addition, includes the connection element 17 has a separate attachment section 19, the connecting element 17 in the region of its contact portion or socket section 20 encloses.

The connection section 18 comprises two contact elements 21, 22, which are spaced apart along the longitudinal axis and have facing each other contact surfaces 23, 24. The Contact surfaces 23, 24 are curved. That is, the two contact elements 21, 22 are curved around a curved curve Axial perpendicular to the longitudinal axis. The attachment section 19 has a tongue 25 which is resilient and in the rebound State protrudes and for fixing the connection element 17 in a receiving chamber 9 is used. In each of the receiving chambers 9 and thus each of the recording channels 11 is starting from the second end face 4 a connection element 17 according to FIG 3 inserted parallel to the longitudinal axis. The connection element 17 is in the associated receiving chamber 9 in the direction of second end face 4 through engagement in a recess supported with a support surface towards the step surface 10, which in the form of openings in the figures 1 and 2 are visible. The support and securing along the Longitudinal axis 2 in the direction of the first end face 3 via which is against the first end face 3 containing end wall of the housing 1 abutting end face of the attachment portion 19 of the connection element 17. For releasing the connection elements 17 are out of the associated receiving chamber 9 the tongues 25 each over one of the openings in the step surface 10 accessible by a tool. It is recognizable that each have a breakthrough in the area of the dividing wall is arranged between two adjacent receiving chambers 9, so that over a breakthrough the tongues 25 of two next to each other arranged connection elements 17 are accessible.

The exposed conductor of the ribbon cable F, attached to the Bottom of the ribbon cable F according to Figure 1 provided are, should with the contact surfaces 23, 24 of the contact elements 21, 22 are brought into contact. For this purpose, the contact pressure element 26 in conjunction with the lid 32. The pressing element 26 includes one of the number of receiving chambers 9 corresponding Number of pairs of spring legs 27, 28, which by a Slot 29 are separated from each other. From Figures 1 and 4 is particularly evident that the two spring legs 27, 28 of each pair are bent in a V-shape to each other and at their free ends in each case a bent support portion 30 have. Each pair, consisting of two spring legs 27, 28, serves to load the ribbon cable F in the area of a conductor in contact with the two contact surfaces 23, 24 of a connecting element 17 are brought should. For this purpose, the pressing member 26 by means of the lid 32nd introduced into the region of the transverse groove 12, in which the connecting elements 17 and contact elements 21, 22 with their contact surfaces 23, 24 are exposed in the region of the receiving channels 11. For this purpose, the pressing element 26 is mounted on the lid 32.

This lid 32 has a insertable into the transverse groove 12 and transversely to the longitudinal axis extending support web 33 which in the V-shaped opening between the pairs of spring legs 27, 28 of the pressing element 26 engages. It owns how in particular from Figure 4 it can be seen, the lid 32 on both sides of the support bar 33 each have a groove 34, 35, in which each a spring leg 27, 28 with its support portion 30, 31 is introduced so that they are on the support surfaces 34 or 35 of the grooves of the lid 32 can be supported.

After the ribbon cable F to the housing 1 with the help of his Breakthroughs and the fastening hook 14 has been set, is the lid 32 together with the pressing member 26 in the Quernut 12 introduced. In the process, the ribbon cable F becomes folded inside and arrives with its exposed ladders each in the region of one of the connecting elements 17, i. between the opposing contact elements 21, 22nd and in contact with their contact surfaces 23, 24. The from a Stainless steel made pressing member 26 is doing deformed, since its spring legs 27, 28 when entering under Force by the support bar 31 elastically to each other to be deformed. They act on the contact elements 21, 22 with the interposition of the ribbon cable F substantially in a direction parallel to the longitudinal axis 2. The lid 32 is through the locking hooks 15 in the open portion of the housing 1, i. latched with this, leaving the lid can not solve. Due to the arrangement and training the contact elements 21, 22 on the one hand and the course of the Spring leg 27, 28 of the pressing element 26 on the other virtually no reaction forces are exerted on the lid. The support is exclusively between the components made of metal, i. the contact elements 21, 22 and the Pressing element 26, allowing a connection between the conductors of the ribbon cable F and the contact surfaces 23, 24 with a high force can take place, which also no change subject. The danger of immediate support on the housing would be made of plastic, i. that the contact pressure would change as a result of creep of the plastic, So this is not the case.

Another advantage is that due to the arrangement the pressing member 26 in conjunction with the lid 32 and the Support bar 33 a high security for the ribbon cable F against Excerpt is given and ensures that the connection elements 17 Practically no extracting power subjected become.

In the lying next to the bridge bridge 36 sections the receiving channels 111 are their partitions with a smaller Height in relation to the bottom surface 107 provided as in the area of the bridge web 36.

The embodiment according to FIGS. 5 to 9 includes a connecting element 117, shown in Figure 6 as a single part is. This connection element 117 differs from the according to Figure 3 by the design and arrangement of the contact elements 121, 122 and the contact surfaces 123, 124. They are also two spaced along the longitudinal axis 102 contact elements 121, 122 are provided, whose contact surfaces 123, 124, however, point away from each other. The connection elements 117 are in the receiving channels 111 and in the receiving chambers 109 arranged so that parts of the contact elements 121, 122 with their contact surfaces 123 and 124 laterally, i. in the direction seen the longitudinal axis 102, via the bridge web 36 in the adjacent Areas of the connection channel or the connection channels 111 project. This can be seen in particular from FIG.

Due to the different design or arrangement of the contact elements 121, 122 is in the embodiment according to figures 5 to 9 also a modified form for the pressing element 126 and the lid 132 in relation to the embodiment provided according to figures 1 to 4.

Thus, the pressing member 126, which is also pairs of Spring legs 127, 128 and has a total of transverse to the longitudinal axis 102 is arranged and the bridge bridge 36 overlaps, in Cross-section of the shape of an omega (omega) approximated. In the area the free ends of the spring legs 127, 128 are outward rolled-up portions 37, 38 are provided. In the field of connection between the two spring legs 127, 128 are located Distributed breakthroughs 42. The lid 132 is along with two the longitudinal axis 102 spaced support ribs 133A, 133B provided that receive the pressing member 127, 128 between them. For this purpose, the cover 132 on its inner surface between the support webs 133a, 133b corresponding to the openings 42 of the pressing element 126 distributed pairs of retaining hooks 41st on, which hold the pressing member 126 movable, so that the rolled-up portions 37, 38 with the end surfaces 39 and 40, respectively the two support webs 133a, 133b can come into contact to a pressing of the pressing element 126 with its spring legs 127, 128 in contact with the contact elements 121, 122 below Intermediate circuit of the ribbon cable F perform effective to be able to. It can be seen in particular from FIG. 9 that the pressing member 126 with its pairs of spring legs 127, 128 receives the contact elements 121, 122 between them. Also in this embodiment, a force is applied directly parallel to the longitudinal axis and a force support essentially only between the parts, made of metal are manufactured and work together, namely the contact elements 121, 122 on the one hand and the pressing member 126 on the other. Furthermore, also here due to the arrangement a good Pull-out ensured, as a positive connection between the lid 132 on the one hand and the housing 101 on the other hand achieved is, because the two support ribs 133 a, 133 b take the bridge bridge 36 between them.
