Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Further advantages, features and details of the invention result from the following description of preferred embodiments and from the drawings; these show in

[0027] FIG. 1 a plug according to the invention from an oblique top view;

[0028] FIG. 2 the plug according to FIG. 1 in partial exploded view;

[0029] FIG. 3 a contact element according to the invention as an U-profile;

[0030] FIG. 4 a safety switching profile according to the invention and the plug according to FIG. 1, viewed from oblique above.

DETAILED DESCRIPTION

[0031] FIG. 1 shows a plug 1. In detail, the plug 1 consists of an insertion nose 16, which is integrally formed on a plug housing 22. Furthermore, the plug housing 22 comprises a signal cable 19.

[0032] Further shown is a first support 8 and a second support 10, which are shown received in the insertion nose 16.

[0033] In addition, a channel 21 is also shown, which is arranged between the first support 8 and the second support 10, whereby the convex shape is formed from the first support 8 towards the second support 10.

[0034] FIG. 2 shows essentially the same view as in FIG. 1, but the two supports 8, 10 are shown in a position pulled out of the insertion nose 16. It can be clearly seen how the two supports 8, 10 are formed as a U-profile 17 in this embodiment.

[0035] It is further shown how the first support 8 forms a first claw 9. In this case, the claw 9 is formed from the first support 8 slowly ascending towards a first bridge 28 and then descends again towards the first support 8 in an almost rectangular arrangement with respect to the first support 8. In the embodiment shown here, a plurality of first claws 9 can be seen.

[0036] Next to this, it can be seen how the second support 10 also has a second claw 11, which is formed from the second support 10 slowly ascending towards a second bridge 29 and then descends back towards the second support 10 in an almost rectangular arrangement with respect to the second support 10. In the embodiment shown herein, a plurality of second claws 11 can be seen.

[0037] FIG. 3 shows an enlarged view of the first support 8. It is shown how the first bridge 28 forms a first limb 23 on the one hand and a second limb 24 on the other. The two limbs 23, 24 form the U-profile 17 with the first bridge 28. The first limb forms the first claw 9 and the second limb 24 forms the first claw 9.1. Furthermore, a joint 27 is let into the first bridge 28 on the other side of the two limbs 23, 24, which can be connected to the signal cable not shown here, in order to be able to pass on signals that have been received.

[0038] FIG. 4 shows a safety switching profile 2 according to the invention and the plug 1 from FIGS. 1 to 3. With regard to the plug 1, the features from FIGS. 1 to 3 are not repeated, whereby the explanations should of course also refer to the plug shown here.

[0039] The safety switching profile 2 consists primarily of a rubber tube 12, to which a first flank 13 and a second flank 14 are foldable formed. The rubber tube 12 encloses a switching profile space 7, which in turn accommodates the first switching profile section 5 and the second switching profile section 6. The two switching profile sections 5, 6 are arranged opposite one another in the switching profile space in such a way that, when pressure is applied to the rubber tube 12, the two switching profile sections 5, 6 can slide into one another in a complementary manner.

[0040] In the process, signals, for example in the form of an electrical resistance, between a first stranded wire 3 in the first switching profile section 5 and a second stranded wire 4 in the second switching profile section 6 are matched with one another and, if necessary, a signal is generated which, when the plug 1 is inserted, is transmitted via the signal cable 19 to a signal processing computer which is not shown in more detail.

[0041] Also shown is a fastening profile 15 into which the respective ends of the two flanks 13, 14 can be clamped for fastening.
