DETAILED DESCRIPTION

(13) Unless otherwise stated, identical reference numerals in the Figures denote identical components, or components corresponding to one another, with the same function.

(14) 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.

(15) 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.

(16) 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.

(17) 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.

(18) 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 and reaching behind the sleeve 4. 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.

(19) 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.

(20) 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.

(21) The cut-outs 6 for accommodating 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.

(22) 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.

(23) 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 (see FIG. 2). 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. Stops 14 are provided in the cut-outs 6. In this case, the stops 14 are in each case provided laterally of the connecting members 13. The stops 14 have recesses 9. In this case, the recesses 9 are configured such that they are configured to be 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. The electrical conductors 2, or only the stranded wires of the electrical conductors 2, extend through the recesses 9.

(24) 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 and are unable to slip out of the basic body 3 laterally, or in the radial direction of the electrical conductors 2.

(25) 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.

(26) 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.

(27) 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.

(28) 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.

(29) 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.

(30) 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.

(31) 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.

(32) 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.

(33) A second embodiment of the insulating connector 1 will be described below in connection with the FIG. 8 to 11.

(34) Here, the insulating connector 1 is designed for contacting four electrical conductors 2, i.e. for contacting two pairs of electrical conductors 2 in each case.

(35) Here, the insulating connector 1 also has a basic body 3. The basic body 3 is formed from a ceramic material. Here, the basic body 3 has a cuboid configuration and has a substantially rectangular cross section in this case. The basic body 3 is surrounded by a sleeve 4, and the basic body 3 and the sleeve 4 are positively connected with a fixing member 5 in a fixed position (see FIG. 8).

(36) As can be easily seen in FIGS. 9 and 11, the basic body 3 has two spaced-apart cut-outs 6, in each of which a pair of electrical conductors 2 is disposed. In the present case, two electrical conductors 2 are in each case connected with a connecting member 13 (crimp). For this purpose, an insulation 15 of the electrical conductors 2 is removed at the ends of the electrical conductors 2 to be connected in each case, in order to expose stranded wires 16. The exposed stranded wires 16 are surrounded by the connecting member 13.

(37) In order to prevent the electrical conductors 2 from being removed from the insulating connector 1 in the longitudinal direction of the electrical conductors 2, two spaced-apart stops 14 are formed in the cut-outs 6. The stops 14 are spaced-apart such that the connecting member 13 is arranged between the stops 14 and the connecting member 13 is laterally, i.e. in the longitudinal direction of the electrical conductors 2, positively delimited by the stops 14. The stops 14 have recesses 9 through which the electrical conductors 2 or the stranded wires 16 are routed. In this case, the stops 14 are configured as material webs protruding into the cut-outs 3.

(38) Here, the cut-outs 6 are open on the sides (see FIG. 9), so that a pair of electrical conductors 2 already connected with a connecting member 13 can be laid into the cut-outs 3 laterally, in the radial direction.

(39) Besides the basic body 3, the insulating connector 1 also includes the ceramic sleeve 4, which here surrounds the basic body 3 and can be pushed onto the basic body 3. The sleeve 4 is configured similarly to the first embodiment described in FIGS. 1 to 7, with a lid 10 with two openings 26 (see FIG. 11) for passing through the electrical conductors 2 and an opening 23 for introducing the basic body 3. The sleeves 3 serves for positively fixing the electrical conductors 2 in the radial direction in the basic body 3.

(40) The fixing member 5 is provided for connecting the basic body 3 and the sleeve 4 with each other. Here, the fixing member 5 is configured as a kind of wire strap with two legs 17, which can be resiliently moved or spread towards and apart from each other in a spring-elastic manner (see double-headed arrow in FIG. 9). The ends of the legs 17 have a bent fixing portion 18, which extends perpendicularly to the legs 17 here.

(41) In this second embodiment, the fixing member 5 is arranged along the outside of the sleeve 4 (and of the basic body 3) in the fixed position. In the fixed position (see FIG. 10), the fixing member 5 rests against a channel-shaped protrusion 19 (see FIGS. 10 and 11) on the sleeve 4, and the fixing member 5 reaches behind the basic body 3 with the fixing portions 18 on the legs 17. For this purpose, the basic body 3 has, in each case, depressions 20 into which the fixing portions 18 of the legs 17 reach.

(42) To protect the fixing member 5, the sleeve 4 has a groove 21, which in each case extends parallel to and between the electrical conductors 2 and in which the legs 17 of the fixing member 5 are accommodated.

(43) For installing the fixing member 5, the sleeve 4 has an inclined portion 22 on each side. When the fixing member 5 is inserted, the two legs 17 are guided with the fixing portions 18 along the inclined portions 22 and pushed apart by the inclined portions 22, and in the fixing position, the legs 17 then snap with the fixing portion 18 into the depressions 20 behind the basic body 3.

(44) In the region of insertion openings 25 for the electrical conductors 2 into the basic body 3, the basic body 3 has thickened portions 24 (see FIG. 9).
