The sealing element 365 is designed to be wider in the transverse direction of the arrangement 10 than the first contact surface 325. The sealing element 365 engages around the outer peripheral surface 330 of the insulating layer 65.

Alternatively to the in FIG. 14 shown arrangement 10 is also conceivable that instead of the sealing element 365, a support member 370 is arranged. The support element 370 may, for example, a particularly pressure-resistant material, in particular a plastic and / or the material of the insulating layer 65, have. The support member 370 has on the circumference a support surface 375, which is formed by way of example cylindrical. The support element 370 derives a transverse force F _Q via the support surface 375 substantially without deformation of the support element 370 from the arrangement 10.

The support member 370 surrounds the insulating layer 65 circumferentially. In this case, the support element 370 extends in the longitudinal direction in a direction away from the first contact element 35 direction.

The first contact device 15 is inserted in a receptacle 380, for example the second contact device 20 of the further arrangement 305. The receptacle 380 has an inner receiving surface 385, which may be cylindrical, for example.

In particular, the creepage distance between the first contact element 35 and the second contact element 40 is kept particularly large by the radially wide configuration of the support element 370.

Furthermore, the arrangement 10 has an additional additional support element 391. The further support element 391 is arranged in the longitudinal direction on a side facing away from the second contact element 40 side of the sealing element 365 spaced from the sealing element 365.
