DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0021] A plug connector designated as a whole with 10 has a housing, which substantially consists of two parts, a first part 100 and a second part 200, which are lockable to each other. In this first part 100, spring contact elements 410 are arranged. In the housing 100, openings 110 are provided, through which can be passed blade contact elements (not shown), adapted to the spring contact elements 410 in a manner known per se, in order to form an electrically conductive connection of the contact elements.

[0022] A support 405 is integrally connected to the spring contact elements 410 (see also FIG. 3). A displacement insulation contact 430 is formed on the support 405, said displacement insulation contact being arranged perpendicular to a plug direction R (FIG. 3) in order to contact and to fix a single-core, insulated cable 304. A clamping element 440 is also integrally connected to the support 405, said clamping element being arranged in the plug direction R seen from the side of the displacement insulation contact 430 facing away from the spring contact element 410. At least one opening 210 is provided in the second housing 200, said opening being adapted to the single-core, insulated cable 304 and serves to accommodate the single-core, insulated cable 304. The single-core, insulated cable 304 is, in this regard, arranged in the second housing part 200 such that it lies on the displacement insulation contacts 430 prior to the assembly of the second housing part 200 to the first housing part 100. This state prior to the assembly is depicted in FIGS. 1 and 3.

[0023] The assembly takes place such that the second housing part 200 is slid in a direction designated with M (see FIG. 3, FIG. 4) in the direction of the first housing part 100, wherein the displacement insulation contact 430 contacts and fixes the single-core, insulated cable 304 in a manner known per se. To this end, the displacement insulation contact 430 cuts through the insulation shell of the single-core, insulated cable 304, partially also the core thereof, wherein it penetrates into the strands of the single-core, insulated cable and thus an electrically conductive connection is formed.

[0024] By sliding the two housing parts 200, 100 into each other, the cable 304 is also pushed onto the clamping element 440 and the clamping element 440 clamps the insulation shell of the cable 304. The clamping element 440 thus serves not only for the fixing of the cable 304, but also for strain relief. This state after the assembly is depicted in FIGS. 2 and 4.

[0025] The two housing parts have locking hooks 140, 240 adapted to each other, which lock into each other and thus hold the second housing part 200 on the first housing part 100.

[0026] The advantage of this assembly is that it is possible in a simple and also automated manner. The plug connector enables the assembly of a plurality of single-core, insulated cables 301, 302, 303, 304 lying adjacent to each other in the manner previously described, wherein these cables are arranged in the plug direction R, thus have a collinear arrangement to the spring contact elements 410. The single-core, insulated cables 301, 302, 303, 304, to a certain extent, align with the displacement insulation contacts 410.

[0027] It is understood that instead of the displacement insulation contacts 410, blade contacts (not shown) can also be provided. It is also, purely in principle, possible to form, not only one displacement insulation contact 430, but a plurality of displacement insulation contacts lying one after another on the support 405. More than one clamping element 440 can also be formed on the support.

[0028] A particular advantage consists in that the spring contact element 410, the support 405, the displacement insulation contact 430 and the clamping element 440 can be manufactured from one single punched part, preferably with a single punching process. After the punching process, only the displacement insulation contact 430 has to be rotated by 90°. Such a manufacturing process is also possible in an automated manner. A great advantage also consists in that the clamping element 440 is formed as a metal part, which is integrally connected to the spring contact element 410, the displacement insulation contact 430 via the support 405. This substantially increases the tensile strength of the single-core, insulated cable(s) in the plug connector housing. The cable is, in this case, no longer held by a clamping element arranged on the housing, but rather by a clamping element, which is connected to the spring contact element 410. In this way, clamping elements in the housing can be dispensed with, which also substantially simplifies the manufacture of the housing, while simultaneously increasing the stability.
