Description

Plastic conduit for cables

Plastic ducts for cables and the like
are known in various embodiments. Such a
Channel is described in German Offenlegungsschrift 2 002 912, for example. The channel shown there loading \ represents a housing for receiving wires, cables,
Lines, hoses or the like. And is with a Deekel
lockable. Housing and cover consist of independent injection molded parts, including a further injection molded part
for connecting individual housing sections.
As a result of these individual elements, the previously known conduit is complex, both in terms of manufacture and in terms of storage requirements.

The innovation specified in claim 1 is the task

based on a conduit made of plastic for cables and

Like. To indicate both the production and the

Storage simplified and laying easier. ^:

An advantage of the duct according to the innovation is seen in \ that development by the already during the production

Combination -between housing and cover only a single- ^

total component is obtained, which can be obtained by folding down |

of the lid and engages at the free ends to a managerial ι

processing channel can be completed. The manufacture 1

this component can be made in the extrusion process, where |

the film hinge that connects the housing to the cover, |

by tapering the wall cross-section at the I

point seen continuously generated during extrusion |

can be. 1

Advantageous further developments of the innovation are in the I

claims swept. According to claim 2, the |

1 longer leg corresponds to the shorter one in height by at least |

the measure of the wall thickness. |

<lT I 11

In this way, a right-angled conduit is created during the subsequent interlocking. The requirements 3 and 4 describe the locking connection on the free ends of the cover part and the shorter leg.

The specified angle of at least 15 ° of the locking surfaces enables the use of an appropriate tool a relatively easy opening of the lid. This can then - as the opening is non-destructive - can be closed again. The one described in claims 5 and 6 The resilient support web ensures that the cover sits firmly on the housing. His gripping overreach of the hook part of the locking groove prevents the locking hook from moving in the locking groove.

The innovation is explained in more detail below with reference to the schematic drawing. The receiving channel 1 shown has two legs 2, 3 of different lengths. The cover part 5 is integrally formed on the longer leg 2 via a film hinge 4 so as to be movable. At the free end 51 of the cover part, the latching hook 52 is formed at an approximately right angle. The resilient support web 53 is located on the same side, but at a defined distance from the latching hook 52. The spring action of the support web 53 is achieved by the relatively small wall cross-section.

At the free end 31 of the shorter leg 3 is the continuous locking groove 6, which on the one hand from the free End 31 of the shorter leg 3 and on the other hand is limited by the hook part 6l.

The connection of the cover part 5 to the shorter leg 3 takes place in such a way that the cover part 5 is bent with its free end 51 in the direction of the locking groove 6. This "turning" is made possible by the film hinge 4.

The tip of the locking hook 51 becomes the insertion opening 62 of the locking groove shortly before the end of this bending process 6 reach.

In this state of turning, the tip of the support web 53 hits the outer surface of the hook part 6l. During the actual latching process, the latching hook penetrates into the latching groove 6 and the latching surfaces on the latching hook and on the latching groove, which are at 15 °, rest against one another in a latching manner. During this process, the resilient support web 53 is pressed in the direction of the interior of the conduit channel which is then formed and rests firmly against the outer surface of the hook part 6l in a resilient manner. The cover part 5 is then at a right angle to the two legs 2 ₅ 3 _S because the longer leg 2 protrudes beyond the shorter leg 3 by the amount of the leg wall thickness ¥.
