DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0031] 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. Spring contact elements 410 are arranged in the first part 100. Openings 110 are provided in the housing 100, through which blade contact elements (not shown) can be passed that are adapted to the spring contact elements 410 in an inherently known manner, in order to form an electrically conductive connection of the contact elements.

[0032] A support 405 is integrally connected to the spring contact elements 410 (see also FIG. 3). An insulation displacement contact 430 is formed on the support 405, said insulation displacement contact being arranged perpendicularly 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 440 being arranged on the side of the insulation displacement contact 430 facing away from the spring contact element 410 when seen in the plug direction R.

[0033] The spring contact element 410, the insulation displacement contact 430 and the clamping element 440 are initially punched out of a single sheet metal element. After the punching process, the spring contact elements 410, the insulation displacement contact 430 and the clamping element 440 lie in one plane. The insulation displacement contact 430 is then rotated by 90° out of this plane by means of twisting in the sense of torsion, as is depicted in FIG. 1, for example. The clamping element 440 is also manufactured by the punching process in this case. It can be unscrewed or twisted just like the insulation displacement contact 430 after the punching process by 90° out of the sheet metal plane (not shown). These method steps can also take place in an automated manner. The great advantage of this manufacturing process is that several insulation displacement contacts 430 and also several clamping elements 440 can be arranged one behind the other. By twisting from the sheet metal plane by 90°, a very simple manufacture of several insulation displacement contacts 430 lying one behind the other and several clamping elements 440 lying one behind the other is possible, wherein all insulation displacement contacts 430 and all clamping elements 440 are arranged in a line in the plug direction (R) (not shown).

[0034] 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 insulation displacement 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.

[0035] The assembly now 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 insulation displacement contact 430 contacts and fixes the single-core, insulated cable 304 in an inherently known manner. To this end, the insulation displacement 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.

[0036] 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.

[0037] 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.

[0038] The advantage of this assembly is that it is possible in a simple and automated manner. The plug connector enables the assembly of a plurality of single-core, insulated cables 301, 302, 303, 304 lying adjacent to one another 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 insulation displacement contacts 410.

[0039] It is understood that instead of the insulation displacement contacts 410, blade contacts (not shown) can also be provided. It is also possible, purely in principle, to form not only one insulation displacement contact 430, but a plurality of insulation displacement contacts lying one behind the other on the support 405. More than one clamping element 440 can also be formed on the support.

[0040] A particular advantage consists in that the spring contact element 410, the support 405, the insulation displacement contact 430 and the clamping element 440 can be manufactured as a component from a single punched part, preferably with a single punching process. After the punching process, only the insulation displacement 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 insulation displacement 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.
