- the current standard stipulates that the connection must withstand a tensile force of 900 N +/- 20 N for one minute, whereby the mobility should be less than one millimeter.
- the invention has the object, a

- the invention proposes that at least one form-fitting part is formed on the inside of the sleeve sheath of the connection cap, which is positively connected to the insulation in assembly target position with deformation of the insulation.
- a form-fitting part may be sufficient, which engages correspondingly deep in the insulation.
- a plurality of form-fitting parts may be formed axially one behind the other in the connection cap, in which case they do not have to penetrate so deeply into the insulation in order to ensure positive engagement.
- a tensile force of 900 N +/- 20 N is achieved according to the standard, which can be maintained even over a minute and ensures a mobility of less than one millimeter.
- a higher current carrying capacity is achieved because no mobility in the axial direction is possible because of the positive connection between the
- Forming part keeps the layer pressed into the deformation of the insulation.
- the device is designed so that by the form-fitting part, if it is in assembly target position a deformation of the
- the additional layer, which the Conductive layer forms is taken along and is pressed into the deformation of the insulation with.
- the layer which forms the conductive layer is not severed by the form-fitting part by the mold-closing part, but the layer is squeezed and formed into a recess or recess formed by the mold-closing part
- Thread forming rib is formed, which protrudes from the inside of the sleeve sheath of the connection cap.
- a thread sufficient to form a relatively far projecting from the sleeve shell rib. If several threads are provided, which forms correspondingly protruding ribs, the ribs do not have to protrude so far, in order nevertheless to achieve and ensure the positive connection between the connection cap and the insulation.
- Forming part has an inner diameter which is smaller than the diameter of the insulation and larger than the diameter or the
- the form-fitting part penetrates into the assembly target position over a part of the thickness of the insulation in this.
- the Actuation of the connection cap for the purpose of
- Connection cap provided an array of key surfaces or the like, so that the
- Connection cap by means of a suitable tool, such as a wrench, is rotatable into the desired position when they are on the
- Forming part has a diameter which is less than or equal to or as the transverse dimension or the diameter of the electrical conductor including insulation and together with the continuous layer, but greater than or equal to
- Connection cap are inserted before then the further attachment process is performed, which is powerful, in which the positive connection
- the form-fitting part is formed at a distance from the mouth end of the connection cap, wherein the distance is preferably greater than the axial extent of the Form gleichvons is or about one-third of the length between the mouth and the bottom of the sleeve
- Connection cap corresponds.
- the insulation consists of hard material, preferably VPE.
- the layer surrounding the insulation consists of elastic material, preferably electrically conductive VPE or EVA.
- the layer is multi-layered.
- the electrical conductor is surrounded by a semiconducting layer or a semiconductive jacket, wherein the conductor is formed from a plurality of wires.
- the insulation may be surrounded by a material having a polymeric matrix and a particulate filler comprising zinc oxide powder, in particular doped zinc oxide varistor powder.
- the conductive layer may be a layer having nonlinear electrical behavior. It can have the following properties.
- the material shows a strong voltage-dependent resistance, which decreases with increasing field strength in a non-linear manner. In the normal state, this works non-linear
- a cable termination is omitted in such a solution. It is merely a connection of the non-linear electrical coating to the
- the effect here is the effect that due to the non-linearity of the wrapping material the

- FIG. 4 shows a detail in FIG
- a Blitzstromableitvorraum which consists of a catching device 1, which is connected via an electrical conductor 2 to a grounding system, not shown.
- electrical conductor 2 is surrounded by an insulation 4, wherein the insulation 4 of a in
- Material is surrounded, which forms a conductive layer.
- the layer 5 is not guided to the end of the insulation 4 to make the arrangement of these layers clear.
- the layer 5 reaches the end of the insulation 4.
- Insulation 4 and the surrounding layer 5, such a cap 6 can be installed.
- the connecting cap 6 is, as shown in particular in Figure 2, sleeve-like design and in the assembly target position with the sleeve casing on the
- the sleeve bottom 7 can as
- Insertion limit for the insulation 4 together with layer 5 serve.
- To the sleeve bottom 7 includes a blind hole 8, in which the stripped end of the conductor 2 is inserted in contact, when the cable is prepared as shown in Figure 1 to 3.
- the connection cap 6 in the region of the blind hole 8 radial threaded holes 9 'for stud bolts 9, with their in the
- Blind end 8 contact the stripped end of the conductor 2.
- the blind hole has a smaller diameter than the terminal cap 6, so that the stripped end of the conductor 2 is fittingly inserted.

- an outer layer of material can be UV-resistant to achieve the appropriate UV protection.
- the electrical conductor 2 may be surrounded by a semiconductive layer 11, as shown in Figure 1 to 3.
- the semiconductive layer 11 protrudes with respect to the insulation 4, but this is illustrated only for the sake of clarity. Normally, the insulation 4 with the semiconducting layer 11 is seen in the axial direction, complete.
