[0067] FIG. 7 shows a sectional view of the embodiment of the insulating connector from FIG. 1, with the sleeve in the fixed position.

[0068] Unless otherwise stated, identical reference numerals in the Figures denote identical components, or components corresponding to one another, with the same function.

[0069] FIG. 1 shows an embodiment of an insulating connector 1 for contacting four conductor pairs composed of eight electrical conductors 2. The insulating connector 1 has a basic body 3, a sleeve 4 and a fixing member 5.

[0070] Of the eight electrical conductors 2, two electrical conductors 2 are in each case electrically contacted with each other. For this purpose, the contacted electrical conductors 2 are inserted into the insulating connector 1 in an opposing manner in each case.

[0071] The basic body 3 is made from a ceramic material and respectively accommodates the contacted electrical conductors 2 in cut-outs 6 (in this respect, see FIG. 4), so that non-contacted electrical conductors 2 are spatially separated from one another and thus electrically insulated, because the ceramic material of the basic body 3 is not electrically conductive.

[0072] In order for the electrical conductor 2 to remain in their position, they are fixed in the cut-outs 6 by a ceramic sleeve 4. For this purpose, the sleeve 4 is pushed over the basic body 3 along the electrical conductors 2. In the process, the electrical conductors 2 are clamped into recesses 9 and thus fixed on the basic body 3. The recesses 9 can be seen in FIG. 4.

[0073] In order for the sleeve 4 to remain in its position relative to the basic body 3, a fixing member 5 in the form of a clamp is provided. The fixing member 5 positively connects the sleeve 4 with the basic body 3 by the fixing member 5 latching into corresponding cut-outs 7 in the sleeve 4 and the basic body 3. The fixing member 5 is configured like a snap-fit connection. Therefore, the connection can be disengaged again by displacing the fixing member 5, so that the sleeve 4 and the basic body 3 can be separated from each other.

[0074] FIG. 2 shows the embodiment of the insulating connector 1 from FIG. 1 in a different perspective. In this illustration, the fixing member 5 is easy to recognize. It comprises a wire brought into shape, which is seated in a recess 7 of the sleeve 4. By pushing in the part of the fixing member 5 protruding from the sleeve 4, the fixing member 5 can be disengaged again, and the sleeve 4 can be pushed off the basic body 3. Thus, the electrical conductors 2 are exposed and can be removed again from the insulating connector 1.

[0075] FIG. 3 shows the embodiment of the insulating connector 1 from FIGS. 1 and 2 with a view onto the basic body 3 on the inside of the insulating connector 1 without a sleeve 4. For separating the basic body 3 and the sleeve 4, the fixing member 5 is removed from the insulating connector 1. The basic body 3 has a through-hole 8 for accommodating the fixing member 5. In the engaged state, the fixing member 5 can thus reach into the sleeve 4 on both sides of the basic body 3 and positively connect the two components with each other.

[0076] The cut-outs 6 the electrical conductors 2 are easy to recognize. In the cut-outs 6, the electrical conductors 2 are mechanically and electrically connected, in each case in pairs, using connecting members 13.

[0077] Webs of the ceramic material of the basic body 3 remain between the cut-outs 6, so that the contacted pairs of the electrical conductors 2 are insulated from one another.

[0078] FIG. 4 shows the basic body 3 of the embodiment of the insulating connector 1 of FIG. 1. The electrical contact connection of the electrical conductors 2 is realized by means of the connecting members 13 The connecting members 13 are configured as crimp connectors whose diameter is greater than the diameter of the electrical conductors 2. The connecting members 13 are disposed in the cut-outs 6.. The cut-outs 6 have recesses 9 to keep the electrical conductors 2 in position. In this case, the recesses 9 are configured such that they are smaller than the dimensions of the connecting members 13 and larger than the diameter of the electrical conductors 2. In this way, the connecting members 13 cannot slip out of the basic body 3 along the direction of the electrical conductors 2.

[0079] When the sleeve 4 is pushed onto the basic body 3, the cut-outs 6 are closed by the sleeve 4, so that the connecting members 13, together with the electrical conductors 2, are fixed in their position

[0080] FIG. 5 shows the sleeve 4 of the embodiment of the insulating connector 1 from FIG. 1. The sleeve 4 is configured to be substantially cylindrical or tube-shaped and integrally connected to the lid 10 on one side. In turn, the lid 10 has four passages 11 for guiding the electrical conductors 2 through. The side of the sleeve 4 opposite the lid 10 is configured to be open for accommodating the basic body 3.

[0081] The cut-outs 7 for the fixing member 5 are arranged opposite, in the jacket surface of the sleeve 4. The cut-outs 7 are configured such that the fixing member 5 can be pushed from the outside through the sleeve 4 and through the through-hole 8 of the basic body 3 and reaches into the cut-outs 7 on both sides of the sleeve 4.

[0082] FIG. 6 shows a sectional view of the embodiment of the insulating connector 1 from FIG. 1, with the sleeve 4 in the released position. The sleeve 4 can be brought into a released position in which the basic body 3 and the sleeve 4 are not connected with each other. In the released position, the electrical conductors 2 can be laid into the basic body 3 and are not completely fixed at first. Rather, by being laid into the basic body 3, the electrical conductors 2 are loosely guided so that they can end up in the completely correct position when the sleeve 4 is pushed on.

[0083] In the released position, the fixed position 5 is also not engaged with the sleeve 4 or the basic body 3. Thus, the sleeve 4 and the basic body 3 can move freely relative to one another in the released position.

[0084] In this illustration, the parallel arrangement of the electrical conductors 2 is illustrated by the depicted center axes 12. The center axes 12 of the electrical conductors 2 to be contacted coincide, so that the electrical conductors 2 to be contacted are arranged so as to be aligned with one another.

[0085] FIG. 7 shows a sectional view of the embodiment of the insulating connector 1 from FIG. 1, with the sleeve 4 in the fixed position. If the sleeve 4 is completely pushed onto the basic body 3, the sleeve 3 is in the fixed position.

[0086] In the fixed position, the electrical conductors 2 are completely fixed by the electrical conductor 2 being routed through the recesses 9, while the connecting members 13 do not fit through the recesses 9.

[0087] In order for the sleeve 4 not to unintentionally leave the fixed position and release the electrical conductors 2 again, the fixing member 5 is pushed in so that the sleeve 4 is positively connected with the basic body 3. In the process, the fixing member 5 is pushed through the cut-out 7 of the sleeve 4 and the through-hole 8 of the basic body 3.
