"Device for screwing on a coaxial cable end a holding element "

The invention is directed to a device for screwing a coaxial cable end to a holding element, in particular a broadband communication cable amplifier housing, with a contact element for the inner conductor and a contact element for the outer conductor of the coaxial cable and with a stop shoulder for application to one Side of the holding element and a screw connection for fixing to the holding element.

From a prospectus of the Pa. Hirschmann in 7300 Esslingen a generic device is known. This known screwing device consists of a Plurality of parts. On the one hand from a screw connection part which has the stop shoulder and which the bore interspersed on the amplifier housing. This element contributes External thread on which a hexagon nut is screwed with a rubber seal in between, so as to hold the device on the housing bore. The known device also has an inner element with in particular the contact for the outer conductor, which via ring seals on the first-mentioned element is fixed. These two elements are connected to one another via screw connections. If the cable is pushed in, after the contacts have been exposed, must first

a grip sleeve can be pushed over the cable end, then a rubber seal. After the cable has been pushed into the screwing device, the grip sleeve is then used pushed over the elements and screwed to them via external / internal thread and pulls over a Drive slope the rubber sealing ring against the outer sheath of the cable.

The known device is extremely complex and particularly in its sealing effect between the outer cable sheath and housing bore limited.

The object of the invention is to create a solution with which the assembly / simplifies and in particular the seal is simplified and made safer between the cable sheath and the screwing device.

In a device of the type mentioned, this object is achieved according to the invention in that behind a support area is provided on the stop shoulder and a shrink-fit tube is provided on the support area is, the shrink tube in the assembly position with a shrinkable, after shrinking on the outer sheath of the coaxial cable is equipped with shrinking area.

The design according to the invention makes the advantages

take advantage of the inherent shrink tubing. With coaxial cable couplings a similar design is already known (DE-GM 82 19 18'4 of the applicant).

In an embodiment, the invention provides that the shrinkable Area is provided with an internal hotmelt adhesive coating, which is also the case with the above Applicant's utility model is realized in the same way.

The invention also provides that the support element for the shrink tube and the contact shoulder to be applied to the Holding element are integrally formed. This design offers compared to the generic state of Technology has the significant advantage that much fewer individual elements are required to insert the entire housing or to design screwing device.

In a further embodiment it can be provided that the support area has a contact-increasing surface for the shrink tube is equipped. This can be, for example, your own hotmelt adhesive coating or a roughened one Surface or the like. More.

The invention is explained in more detail below with reference to the drawing, for example. This shows in the only one Figure a screwing device with inserted

Coaxial cable end, partially cut.

From a broadband communication cable amplifier housing not shown in detail only one retaining plate 2 having retaining bores is shown.

In the bore 1, the generally designated 3 device with a threaded element 4 is used over which a hex nut 5 can be screwed.

On the underside of the holding plate 2, the device 3 has a further hexagonal screw 6, which has a contact shoulder 7 forms for application to the holding element 2. The hexagon nut 6 can with the housing area 8, the is essentially cylindrical, electrically be made conductive in one piece.

In the housing part 8 designed as a hollow cylinder, the interior of the contact cage for the inner conductor 10 and the Contact cage 11 housed for the outer conductor 12, of course these two cages against each other are installed in an electrically insulated manner, which, however, does not matter in this context.

The hollow cylinder area 8 at the same time provides the support area for a shrink tube shrunk there 13, which is one of the shrunken area in the

At least the still shrinkable area 14 of the Shrink tubing 13 is on its inside with a Hot melt adhesive coating 17 provided.

It can be seen by shrinking the area 14 of the shrink tube 13 onto the jacket 15 of the coaxial cable 16 a completely tight connection between the support area 8 on the one hand and the coaxial cable 16 on the other hand generated. In the area of the stop shoulder 7, an annular seal can also be provided around the bore 1. This is indicated in the drawing and designated by 18.

Of course, the described embodiment of the invention can still be modified in many respects without to leave the basic idea. In particular, the invention is not directed to a special design of the support area 8 limited. This can have a shape deviating from the cylindrical shape, just like the invention not on the special design of the contact cages for
