Connection sleeve for a coaxial cable with a thin inner conductor.

The innovation relates to a connecting sleeve for a coaxial Cable, consisting of an electrically insulating plug-in sleeve matched to the outer conductor of the cable Diameter of the receiving hole, from contacting devices for the outer conductor and a stiffening sleeve for the inner conductor of the cable.

There are already connection devices for coaxial Known cables in which the ends separated from the cable jacket are inserted into insulating connecting sleeves are »Within these connecting sleeves, each the outer conductor makes contact, while the inner conductor is discharged to the outside again through an opening on the face side will. Difficulties are encountered when inserting very thin inner conductors because of the opening can be missed due to the distance within the connecting sleeve; even if this opening is funnel-shaped extended and extended to the outside as a stiffening sleeve for the ■ inner conductor.

The task for the innovation now consists in the introduction and stiffening of thin inner conductors improve coaxial cable ends. The task is set according to the innovation with the help of an initially The connection sleeve described is solved in that the stiffening sleeve is displaceable in the end face Opening of the connecting sleeve is arranged.

When assembling a plug-in device for the ends of coaxial cables, it is necessary to provide kink protection for thin inner conductors through the the inner conductor is stiffened and protected. The advantage of the innovation can now be seen in the fact that with this connecting sleeve is given a safe introduction and sufficient stiffening. The introduction of the The inner conductor is so simple and safe especially because the stiffening sleeve for the inner conductor is near the end of the insertion hole at the start of assembly. By pushing in the cable sheath At the remote end of the cable, the stiffening sleeve is pushed in and occurs at the front opening of the insulating connecting sleeve up to a predetermined stop. In addition, that is backward. wärtige, remaining inside the end of the stiffening sleeve expanded funnel-shaped, so that the introduction

the stiffening sleeve can be determined and controlled either by a given paragraph dimension for the cable end, by appropriate stops, or by markings on the stiffening sleeve, which are visible, for example, after it has been fully pushed out.

The innovation will now be explained in more detail with reference to three figures.

In the upper part of FIG. 1, the outer design of the connection sleeve 1 is shown, the outer diameter corresponding to the corresponding inner diameter of a connection socket. Corresponding paragraphs serve as stops for the final assembly. In the lower part of Figure 1, the inner design of the connecting sleeve 1, which consists of insulating material, is explained in more detail in a partial section. The stiffening sleeve 3 for receiving the inner conductor to be inserted later is located in the interior, arranged concentrically. The stiffening sleeve 3 is arranged displaceably in the frontal bore 9 of the connecting sleeve 1 and is withdrawn before assembly in the inner part. The inner end of this stiffening sleeve 3 is provided with a funnel-shaped enlargement 6, through which the introduction of the inner conductor is additionally facilitated; the outer end is preferably closed. Since this funnel-shaped extension or the end of the stiffening sleeve is pushed far into the interior _y , the inner conductor can be inserted much more safely, since the distance from the insertion hole 8 is very small. The funnel-shaped extension 6 can therefore be found very easily with the inner conductor to be inserted, which is then already guided at this stage. The outer conductor is contacted via spring contacts 2, which can be contacted to the outside through corresponding cutouts 7 in the contact sleeve 1.

FIG. 2 now illustrates the initial stage of assembly, in which the cable end separated from the cable sheath is inserted into the insertion hole 8 of the connecting sleeve 1. It becomes clear that the inner conductor 5 already detected in the first introductory phase by the funnel-shaped extension 6 and onto the bore the stiffening sleeve 3 is centered. Through the

inserted stiffening sleeve 3 ensures early guidance of the thin inner conductor. a resilient contact can also be selected, 5

FIG. 3 now shows the final state of assembly, with the remote cable end fully inserted into the connecting sleeve is inserted. The reinforcing sleeve 3 was replaced by the cable insulation, the dielectric, that was moving up is located between the inner conductor 5 and the outer conductor 4 and rests against the funnel-shaped extension 6, pushed outwards. The contacting of the inherently thin inner conductor 5 is thus suitable for the further connection. Corresponding markings or stops on the stiffening sleeve 3 or on the end of the cable facilitate detection of the final assembly state. So z. B. serve the funnel-shaped extension 6 as an inner stop. the The outer conductor 4 is contacted with the aid of the springs 2.

With the help of these connecting sleeves it is also possible to achieve a corresponding type conversion by choosing a suitable type Achieve, as the required diameter ratios can be matched accordingly. The fixation of the Cable end within the connecting sleeve 1 can in various ways, such as by gluing, clamping or Screw connection.

Inflow

Connection sleeve for a coaxial cable with a thin inner conductor.

The innovation is a connecting sleeve (1) for a coaxial cable, especially for thin inner conductors (5). When the cable end is inserted, the inner conductor (5) becomes a stiffening sleeve that can be pushed in the longitudinal direction (3) which is then inserted by pushing the end of the cable through a front opening (9) of the Connecting sleeve (1) is pushed outwards. Fig. 1.
