Description

GERMAN

The invention relates to a distributor or end plate, in particular an end plate for Terminations of telecommunication cables, with several juxtaposed, staggered with gaps Rows of solder connections or solder lugs to which the lines to be connected are from the outside the distribution plate are brought up, in which the soldering connections in rows on opposite the Plate level lie at different heights.

The constantly increasing density of the telecommunications network makes - especially in the networks of large cities · - the distribution points need to be enlarged. However, there are limits to this; because As is well known, the cables are laid underground in the streets, while the distribution points must be positioned above the surface of the earth in the streets. The housing of the distribution points must therefore not become too large in order to avoid impaired visibility to motor vehicle traffic disturb.

The housing size of the distribution points is determined by the terminations of the telecommunication cables. Their size, in turn, depends on the dimensions of the several adjacent rows λόπ solder connections or solder lugs to connect the individual cable cores supporting end plates made of insulating material dependent.

It is known that the soldering connections or the soldering lugs are parallel to each other in the case of distribution or termination plates To arrange rows on the plate and to stagger these rows in the longitudinal direction in such a way that adjacent solder connection rows are each staggered to a gap. It is with the known designs usual, the solder connections in the outer rows - based on the level of the distributor or End plate - to hold lower than the connections in the inner rows. This results in a Step-like height graduation from the sides towards the center of the distributor or end plate the solder connections. As a result, the solder connections of the inner rows are from the side The cable cores fed in are higher than the cable cores connected to the connections in the outer rows. If the circuit connection is to be changed in the outer rows, the soldering iron must be used between the cable cores leading to the inner rows. That is without Damage to these cores is only possible if the mutual distance between adjacent cable cores and so that the solder connections is relatively large.

The invention now has the task of constructing such distribution or end plates - in particular the termination plates for terminations of telecommunication cables - ■ to change that Distributor or end plate,

especially end plate

the mutual distance between the soldering connections can be kept smaller than before, to thereby make room to save and z. B. in a cable terminations or distributor receiving housing with the previously usual dimensions to be able to accommodate a much larger number of cable cores.

This object is achieved according to the invention in that in a distributor or closure plate of the type mentioned, the height of the solder connections above the plane of the plate. Margins the plate decreases towards its center.

This measure makes it possible to move the soldered connections much closer together.

Each solder connection point is because of the decreasing towards the center of the distributor or end plate Height of the soldered connections in a trough that is delimited by all connections and is open at the top therefore freely accessible for a pointed soldering iron without running the risk of using any other part to get in touch. The cable terminations are made by reducing the dimensions of the end plate about a third smaller. This is correspondingly reduced with the same number of cable cores Housing for the distribution points. If you keep the same size of the housing, you can use this Way about half more cable cores can be accommodated.

In addition to facilitating the switching, in particular

So the switching work is one with this downsizing Saving of casting compound and other material and a substantial reduction in the price of the terminations and the housing for the cable distributor. It is also natural for visibility in traffic

Claims (2)

It is of great importance to get by with a smaller housing for the distribution points or to be able to accommodate more cable cores in the housing previously used with increasing telephone density. In the case of a distribution or termination plate, in which the soldered connections are embedded in insulating cones protruding over the plate, which in addition to isolating the connections also have the task of preventing the connections from being accidentally bent, the distances between the adjacent soldered connections can be reduced by moving closer together the cones become so small that it makes difficulties to pass the cable cores leading to the inner solder connections between adjacent cones. In order to increase this distance between the insulating cones without having to make the distance between the soldering connections correspondingly larger at the same time, in a further embodiment of the present invention the flat soldering connections made of strip material are arranged transversely to the axis of the rows of soldering connections and the insulating cones surrounding the soldering connections are flattened in such a way that the main axis of its cross-section is also transverse to the direction of the rows of solder connections. The insulating material cones of the outer rows expediently protrude from a continuous insulating material back which is just high enough for the cable cores fed laterally to the inner rows of soldering connections to pass over it unhindered. These cable cores then lie between the insulating cones of the outer rows of soldered connections. The back of the insulating material is expediently kept somewhat wider than the longitudinal extent of the insulating material cones, so that a corresponding gradation is created; it thereby forms an additional mechanical reinforcement of the distributor or end plate. The design of the connection ends is of particular importance for facilitating the switching work in spite of the soldered connections being pushed together. As noted above, the cable cores are fed to the soldered connections from the side. In order to be able to easily insert the bare end of such a wire from the open side of the structure into the solder connection and solder it to it, the outer end of this connection is designed as a trough which is open to the freely accessible side and transversely to the row of solder connections. The solder connection end expediently consists of individual tongues, of which adjacent tongues are each bent apart towards opposite sides. Three tongues are sufficient for reliable fastening, of which the middle one is bent apart to one side and the two outer tongues are bent apart to the other side. If the distribution or termination plate is provided with a hood-like cover, openings are made in the side walls of the cover through which the cable cores are led to the soldered connections. The object of the invention is shown in the drawing using an example. 1 shows a cross section through an end plate for a cable termination, FIG. 2 shows a broken part of a side view rotated by 90 ° compared to FIG. 1 with the omission of the side wall facing the viewer, FIG. 3 shows a broken top view of one end the end plate, FIG. 4 a side view of a solder connection end with an inserted cable core, FIG. 5 a plan view of the solder connection end. The end plate 1 made of insulating material carries four rows I1 3, 4 and 5 of solder connections, which are arranged parallel to each other and within each half 2 and 3 or 4 and 5 are longitudinally displaced against each other in such a way that - as can be seen from Fig. 3 - Adjacent row of connections are offset to a gap. The soldering connections 6 and 7 are pressed around with insulating material cones 8 and 9, the cones 8 of the two inner rows of soldering connections 3 and 4 being held much lower than the cones 9 of the two outer rows 2 and 5. In addition, the cones 9 of the two outer rows 2 and 5 are still placed on a continuous insulating material back 10. In this way, a trough-shaped arrangement of the soldering anao connections formed by the four rows of soldering connections, which can be clearly seen from FIG. 1, is created. The solder connection space of the end plate 1 is laterally delimited by walls 11 of a cover, which are provided with holes 12 for passing the individual cable cores 13 through. The end 14 (Fig. 4 and 5) of the solder terminals 6 and 7 consists of three tongues, of which the middle one is bent on one side, the two outer ones on the other side, so that they each have a transverse to the row of solder terminals in Form the trough lying in the direction of the cable cores to be connected 13 (cf. FIGS. 2 and 4). The trough is open on the freely accessible side. So you can easily insert the bare ends 15 of the cable cores 13 in the troughs of the ends 14 and solder the two parts together. As can be seen in particular from FIGS. 1 and 3, despite their compact arrangement, all soldering points are easily accessible without the risk of coming into contact with any other parts of the circuit structure. The present invention can of course be used with any distribution plates in which a large number of connections must be accommodated in a small area and in which these connections are to be easily accessible when connecting conductors are brought up to the side. The connections can of course also be screw connections. PATENT REQUIREMENTS: 1.
