Description

Screw connection with hose connection for cables or lines

The innovation concerns a screw connection with hose connection for cables and lines in the generic term of claim 1 mentioned Art.

An opening in the housing wall is used to guide lines and cables through the housing walls

.15 so-called screw connections with hose connection used. These screw connections are formed by a pipe socket with an external thread at one end and at the other end has a hose connection part in the form of a hose nozzle. The pipe socket has in the middle a hexagonal collar. For running in or out of lines and cables in or out of a housing the pipe socket is inserted into an opening from the outside and screwed with a nut from the inside. Since accessibility for the mother must always be taken into account, the lines cannot be attached to everyone Any point of the housing can be brought out, so that freedom of movement is restricted. In the known design, it is also necessary to ensure that the lines inside the housing do not come to rest on the sharp edges of the screw connection. This is done by attaching additional cable clamps or rubber blanket avoided.

The innovation is based on the task of a screw connection with a hose connection for the out or infeed of cables from or in housings such as equipment boxes, cable ducts and the like to indicate the Compared to the usual screw connections, all operations required for assembly, such as screwing including countering and attaching the hose and the hose clamp, from the outside and Furthermore, through the shaping in the area of the line routing, the lines passed through are protected from injuries the insulation better protects.

According to the innovation, this object is achieved by the measures specified in the characterizing part of claim 1 solved.

With the new screw connection, the attachment of outlets and Inlet for lines and cables much easier and also made possible in hard-to-reach places, since a counter-holding by means of a There is no need for tools inside the housing. In addition, it is not necessary to attach additional cable clamps or a rubber blanket.

The innovation is shown in the drawing. Show it:

Fig. 1 is a section through a conduit with an outlet for lines,

Fig. 2 is a view of a screw connection with partial section and

FIG. 3 shows a cross section to FIG. 2.

In Fig. 1, 1 designates a housing of a conduit in which a bundle of lines 2 is guided is. To run the lines, an opening is provided in the housing wall, into which a pipe socket 3 is inserted from the inside.

This pipe socket 3 has - as also FIG. 2 shows at one end a hose connection part 10 and at the other end a collar 11. This collar 11 is used to support the interior of the housing 1. The outer and inner edges that can come into contact with cables are well rounded to prevent damage to the Avoid isolating the lines. On the side of the collar 11 facing the housing wall (between Collar 11 and housing neck 8) a groove 7 is provided which receives a sealing ring 7a, which also serves as anti-twist protection for sealing.

A threaded neck 8 with an external thread is used for fastening by a nut 4 that can be pushed on from the outside. and a polygonal piece 9 provided for countering by means of a tool (see FIG. 3). The hose connector 10 at the other end of the pipe socket 3 is designed as a conventional hose nozzle. One pushed over it Hose 5 is held in place with a clamp 6.

Instead of the polygon used for counter-holding, other known means can also be used or corresponding ones Measures are taken. For example, it is possible to provide a groove in the opening of the housing 1 and to arrange a nose or the like engaging in the groove on the pipe socket.

Claims (2)

_ 4 - VPA 8! P 3 1 3 3 DE claims for protection 1. Screw connection with hose connection for cable or Lines which are passed through an opening in the wall of a housing, in which a pipe socket a Hose connection part, means for counter-holding and an external thread and in the opening of the housing can be inserted into the wall and screwed tight by means of a nut, thereby identifying net that on the opposite of the hose connection part (10) At the end of the pipe socket (3) a collar (11) is arranged, to which a threaded neck (8) is connected, that the pipe socket (3) from the interior of the housing (1) can be inserted into the opening, the The collar (11) rests against the inside of the housing (1) so that the nut (4) from the outside over the hose connection part (10) and, if necessary, slidable via the counter-holding means and onto the threaded neck (8) can be screwed on and that the surface of the collar (11) protruding into the housing (1) is rounded. G 2. Screw connection according to claim 1, characterized that between the collar (11) and the threaded neck (8) a groove (7) for receiving one at the same time is provided as a rotation protection serving sealing ring (7a).
