first embodiment
[0035]FIG. 1 shows a plug protection device 1.
[0036]The plug protection device 1 has an annular holding section 2, which has an inner surface wall 3 which delimits a through-opening 4 of the annular holding section 2.
[0037]As can be seen from the sectional illustration of FIG. 2, the inner surface wall 3 is adapted with regard to its shape and size to an outer surface wall 5 of a shoulder 6 of a sensor housing 7 of a sensor 8 in such a way that the annular holding section 2 of the plug protection device 1 is able to be mounted in a form-fitting manner onto the shoulder 6 of the sensor housing 7.
[0038]The plug protection device 1 has at least one protection lug connected with the annular holding section 2, in the case of the present first example embodiment precisely two protection lugs 9.1, 9.2, which extends away from a face side 2a of the annular holding section 2, which in a mounted arrangement of the plug protection device 1 on the shoulder 6 of the sensor housing 7, as can be s...
second embodiment
[0045]In the second embodiment according to FIG. 6, the plug protection device 1 has precisely three protection lugs 9.1, 9.2, 9.3 connected with the annular holding section 2, which extend away from the face side 2a of the annular holding section 2, which in a mounted arrangement of the plug protection device 1 on the shoulder 6 of the sensor housing 6 faces an electric connection socket 11 of the sensor 8 configured for the contacting reception of an electric plug 10, in such a way that the protection lugs 9.1, 9.2, 9.3 extend at a distance from one another and at least substantially parallel to one another in the insertion direction R, so that in a mounted arrangement of the plug protection device 1 onto the shoulder 6 of the sensor housing 7 of the sensor 8, in which also the electric plug 10 is inserted into the electric connection socket 11 of the sensor 8, the electric plug 10 is mechanically limited on at least three sides of the electric plug 10 by the three protection lugs...
third embodiment
[0047]In the third embodiment according to FIG. 7, the plug protection device 1 has only a single protection lug 9.1 connected with the annular holding section 2, which protection lug extends away from the face side 2a of the annular holding section 2, which in a mounted arrangement of the plug protection device 1 on the shoulder 6 of the sensor housing 6 faces an electric connection socket 11 of the sensor 8 configured for the contacting reception of an electric plug 10, in such a way that the protection lug 9.1 extends in the insertion direction R along its length and fits around the plug 10 here in an arc shape in an arcuate angle of between 90 degrees and 270 degrees, in particular of 180 degrees, so that in a mounted arrangement of the plug protection device 1 onto the shoulder 6 of the sensor housing 7 of the sensor 8, in which the electric plug 10 is inserted into the electric connection socket 11 of the sensor 8, the electric plug 10 is mechanically limited over a partial ci...
