DETAILED DESCRIPTION

(9) FIG. 1a shows a contact holding plate 11 with lamellae 114 which serve to hold plug-in contacts 3 and the ground contact pin 3′. To this end, the plug-in contacts 3 and the ground contact pin 3′ can be inserted through contact openings 110 on the cable connection side. Furthermore, the contact holding plate 11 has a plurality of latching lugs 111 with in each case one latching window 112 for latching to a contact carrier 12.

(10) FIG. 1b shows an oblique plan view of the contact carrier 12, that is to say, looking obliquely at the cable connection side of said contact carrier 12. This contact carrier 12 has a plurality of contact chambers 120, which are open on a cable connection side, for receiving in each case two contacts 3. Opposite the cable connection side, the contact chambers 120 have in each case two passage openings which are not shown in the drawing and therefore are not provided with a reference sign. At these passage openings, the contact carrier 12 has hollow-cylindrical moldings 124 on the plug-in side for receiving in each case a plug-in region 32 of a respective one of the contacts 3. Furthermore, the contact carrier 12 has latching pegs 121 to which the latching lugs 111 of the contact holding plate 11 can latch. The contact carrier 12 also has a ground contact chamber, not denoted in any detail for reasons of clarity, for receiving a ground contact pin 3′.

(11) FIG. 1c shows the mounted insulating body 1, that is to say, the contact carrier 12, to which the contact holding plate 11 is latched by way of its latching lugs 111, wherein the latching windows 112 latch on the latching pegs 121, and wherein the lamellae 114 engage into the contact chambers 120. The ground contact pin 3′ is also illustrated.

(12) FIG. 1d shows the contact holding plate 11 looking at the lamellae 114 from the plug-in side.

(13) FIG. 1e shows a side view of the mounted insulating body 1.

(14) FIG. 1f shows a plan view of the insulating body 1 with inserted plug-in contacts 3, that is to say, looking at the contact holding plate 11.

(15) FIGS. 2a and 2b show a connecting element 4 which has two contact receptacles 40 into each of which a plug-in contact 3 can be inserted by way of its plug-in region 32 in an interlocking and force-fitting manner.

(16) According to one particularly advantageous embodiment, the connecting element 4 consists of metal, in particular of brass, and is of flat design. This ensures a high degree of robustness, excellent long-term stability and at the same time a small space requirement.

(17) The at least two contact receptacles 40 of the connecting element 4 of the illustrated embodiment are each formed by an open ring. The round ring shape is particularly advantageous because the plug-in contacts 3 which are to be inserted therein are of rotationally symmetrical design.

(18) The open ring is formed by way of the at least two contact receptacles 40 of the connecting element 4 each having two sickle-shaped arms 41, the ends of which are directed toward one another. The two ends are therefore separated from one another by an opening 400. This is particularly advantageous because, owing to the configuration of the specific form thereof, the desired elasticity which is required in order to receive the plug-in contacts 3 with a desired contact force can be set with the greatest possible stability.

(19) FIGS. 3a and 3b show the plug-in contact 3. Said plug-in contact has a cable connection region 31, which is designed as a crimp region, and a plug-in region 32. An encircling collar 34 is located between said cable connection region 31 and plug-in region 32 on the cable connection region side. On the plug-in region side, a connecting region 30 by way of which the plug-in contact 3 can be inserted into the contact receptacles 40 of the connecting element 4 adjoins the collar 34.

(20) FIGS. 4a and 4b show an oblique plan view and a side view of two plug-in contacts 3 which are inserted into in each case one of the contact receptacles 40 of the connecting element 4. The respective plug-in region 32 is guided through the contact receptacles 40 and the plug-in contacts 3 make contact with the connecting element 4 by way of their connecting regions 30. In this case, the connecting element 4 encloses the connecting regions 30 by way of its contact receptacles 40 in an interlocking and force-fitting manner.

(21) FIG. 5a shows the mounted insulating body 1 with plug-in contacts 3 which are partially inserted and partially to be inserted. In this case, four connecting elements 4 are inserted into in each case one contact chamber 120 and are fixed in the insulating body 1 by way of interaction of the contact holding plate 11 with the contact carrier 12 which is latched to said contact holding plate.

(22) FIG. 5b shows a side view of the same arrangement. In this case, it is clear that the plug-in regions 32 of the contacts 3 which are already inserted are received in the hollow-cylindrical moldings 124, wherein the hollow-cylindrical moldings 124 protrude beyond the plug-in regions 32 on the plug-in side.

(23) Even though various aspects or features of the invention are shown respectively in combination in the figures, it is clear to a person skilled in the art—unless stated otherwise—that the illustrated and discussed combinations are not the only ones possible. In particular, mutually corresponding units or feature complexes from different exemplary embodiments can be exchanged with one another.

(24) Put another way, aspects and features of the various embodiments described above can be combined to provide further embodiments. These and other changes can be made to the embodiments in light of the above-detailed description. In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled.
