DE1044208B - Airtight container under internal pressure from several parts connected to one another by soldering, in particular longitudinally or transversely divided connecting sleeve, end closure or the like for telecommunication cables under internal pressure - Google Patents

Description

GERMAN

The airtight containers built into electrical cables, such as connecting sleeves, mostly exist of several parts connected to one another by soldering. So it is common to use the connection sleeves as Run longitudinally split sleeves from an upper and lower part 5, which at the abutting edges are soldered together airtight. If such sleeves are under internal pressure, ζ. B. for telecommunication cables, for monitoring the tightness of the cable jacket including the connection sleeves and other fittings are filled with a pressurized gas, the solder seam is mechanically stressed, and there is a slight risk of the solder seam leaking. In such cases there is a Relief of the solder seam is desirable.

For this purpose, it is already known in the case of cable sleeves that the sleeve parts to be connected to one another are attached to their Flange connecting edges and attach them to the flanged connecting edges by means of tensioning rails hold together like brackets. Another type of connection that has become known exists in that the connecting edge of one container part around the connecting edge of the other container part is beaded. However, these known types of connection cannot be considered satisfactory for this reason alone can be seen because at high internal pressures the forces acting on the clamps can be so large that they bend open the slide rails or the comprehensive edge of one container part and thus cause a leak at the soldered seam. In addition, the molded connecting parts, the slide rails and the beaded connection edges due to their elastic after-effect endeavor to take on their original shape again, so that as a result of the elastic see After-effects there is already a risk that the initially intimate connection of the connecting parts is resolved. In addition, the known cable sleeves have the disadvantage that the separation of the Socket parts, as can be readily seen, is cumbersome and time-consuming. The same goes for a another known embodiment of airtight containers. This consists of a middle one, from two half-shells assembled container part and two each with one side of the middle container part connected end parts. These items are expanded like a flange at their connecting edges and on these extensions by means of rivets tied together.

In particular, longitudinally split connection sleeves for telecommunication cables under internal pressure have become known in which the side edges of the sleeve half-shells are bent radially outward and the radially directed under internal pressure formed in this way are airtight

External flanges by riveting and by soldering to one another are connected. But even with this version, the outer flanges are subjected to bending stress, which requires a sufficiently thick socket wall. The rivets are both on tension and also stressed in bending and must therefore be made sufficiently thick. Further there is the disadvantage that the intended soldering on both the top and the bottom the riveted flanges must be made.

The invention relates to a novel design of airtight containers under internal pressure of several parts connected to one another by soldering, in particular parts which are longitudinally or transversely divided Connection sleeves, terminations or the like for telecommunication cables under internal pressure. The invention consists in that the soldering edges overlap in the direction of the container walls and by cap screws as well as by one covering the screw heads and the outer overlap seam Solder bead are connected to each other.

Various advantages are achieved by the invention, which summarize the known designs not have. Due to the mutual overlapping of the soldering edges in the direction of the container walls is first made possible, the wall of the container thin-walled, there no parts of the container wall are subjected to bending stress. The head bolts are only on shear

3 4 claimed, so that it is advantageously connected to at least one tab. According to the thin and consequently fine thread Fig. 6 is a longitudinal tab 14 with which can be made and thus also with a sleeve top by rivets 15 inextricably connected, thin container wall in the associated thread This creates a design that has a sufficient hold approximately after the inner soldering edge .., S correspond to the inward cranking of the upper part The outer overlap seam is screwed to the bracket 14 by a continuous screw 12. As with the solder bead, complete air is also visible under internal pressure, the tightness facing the solder bead 13 is achieved 12 have a low head with head screws, the io is a protruding head f executed. Furthermore, the amount of tin required for the soldering small amount. The order is made in such a way that the rivet heads and the guarantee are given that at very high inside the screw heads are pressed in in the circumferential direction and the container parts are firmly connected to each other. This ensures that the solder bead 13 remains as smooth as possible and that there are no mutual displacements. Subsequently, elastic deformations can assume a straight-line course. no longer occur because * these connections by the screw In the embodiments according to FIGS. 7 and 8 sufficient resistance is provided. At the same time, one or both soldering joints are cranked. Within the scope of this inventive concept, changes are made and an additional tab, various advantageous embodiments are possible. used. In FIG. 7, the soldering edge of the upper part is an expedient embodiment, 20 part outwardly and the soldering edge of the lower part the soldering edge of one container part outwardly or inwardly angled.
