DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0025] A device 1 for receiving a data carrier according to one exemplary embodiment of the invention is depicted in FIG. 1. It consists of a receiving body 11 and a fixing pin 12, which are formed in one piece made of steel. The receiving body 11 is circular-cylindrically shaped and has six engaging recesses on its peripheral surface for a tool. The receiving body 11 is partially hollow, such that it has a circular-cylindrical receiving region 111 which is accessible from one end of the receiving body 11 by means of a circular opening 112. The other end of the receiving region 111 is closed. The circular-cylindrical fixing pin 12 is arranged in the middle of the closed end. In the present case, this has a length of 14 mm and a diameter of 4 mm. Its end facing away from the receiving body 11 has a conical region 121.

[0026] As shown in FIG. 2, the data carrier 113 is arranged in the receiving region 111 in such a way that it fills this up and protrudes beyond it. The data carrier has a plastic housing, the external diameter of which corresponds to the internal diameter of the receiving region 111 and the opening 112. A data-storing microchip and an RFID antenna are arranged inside this housing in such a way that the RFID antenna is located outside the receiving region 111.

[0027] An expanding rivet 2 of a data carrier set according to one exemplary embodiment of the invention, which serves to fix the device 1 in a conical bore, is depicted in FIGS. 3 and 4. Expanding rivets are principally known, for example, from DE 298 20 121 U1. The expanding rivet used in the data carrier set has a disc-shaped base body 21. An opening 211 goes straight through the base body 21 along the longitudinal axis L of the expanding rivet. The internal diameter of this continuous opening 211 is 4 mm and thus corresponds to external diameter of the fixing pin 12. Four spring elements 221, 222, 223, 224 are arranged on one side of the base body 21 in such a way around the continuous opening 211 that they are angled away from the longitudinal axis L from the continuous opening 211. If the spring elements 221, 222, 223, 224 are pressed together in such a way that they run in parallel to the longitudinal axis L, then they form a channel interrupted on its internal walls, the diameter of which corresponds to the diameter of the continuous opening 211. The external walls of the spring elements 221, 222, 223, 224 thus form an interrupted circular cone, the external diameter of which is 7 mm. The interruptions, both of the channel and of the circular cone, thus take place through slots that, in each case, separate two of the spring elements 221, 222, 223, 224 from each other.

[0028] In FIG. 5, it is depicted how the device 1 can be inserted into the expanding rivet 2 as part of the data carrier set. Since the spring elements 221, 222, 223, 224 of the expanding rivet are still in their initial position here, fixing the device 1 does not yet take place. This arrangement of the data carrier set only serves for illustration. To fix the device 1 on the engine block, it is rather provided that, initially, the expanding rivet 2 is inserted into a conical bore of the engine block and subsequently the fixing pin 12 of the device 1 is introduced into the expanding rivet 2.

[0029] This is depicted in FIG. 6. The object 3, embodied here as an engine block, has two conical bores 31 with an internal diameter of 6.6 mm in each case. Initially, an expanding rivet 2 was arranged in one of these bores and then the fixing pin 12 of a device 1 was inserted into this through the continuous opening 211 of the expanding rivet. Since the internal diameter of the conical bore 31 is smaller than the external diameter of the circular cone, which is formed from the spring elements 221, 222, 223, 224 of the expanding rivet 2, the spring elements 221, 222, 223, 224 are thus squeezed in between the fixing pin 12 and the internal walls of the conical bore 31. Thus, they exert a force on the fixing pin 12 which holds this in the expanding rivet 2 and thus on the engine block.

[0030] It was determined in a tensile test that an attraction force of 139 N was necessary in order to pull the device 1 out of the expanding rivet 2 again. By doing so, the expanding rivet remained intact.

[0031] In order to check whether the mechanical strength of the device 1 and the expanding rivet 2 is sufficient in order to withstand the load to which they are subjected during a production process when being arranged on an engine block, they were subjected to a sine duration test according to DIN 60068-2-6 standard in a frequency range of 10 to 2000 Hz at a checking level D/A of 3 mm pp/20 g and a transfer frequency of 57.55 Hz for 20 cycles (40 sweeps). Furthermore, they underwent two shock tests according to EN 60068-2-27 standard with a half sine curve shape and 20% compensation pulses with 25 positive pulses and 25 negative pulses. In the first shock test, the peak acceleration was 50 g and the pulse length was 11 ms. In the second shock test, the peak acceleration was 100 g and the pulse length was 6 ms. Finally, the device 1 and the expanding rivet 2 underwent a shock duration test according to EN 60068-2-29 standard with a half sine curve shape and 20% compensation pulses. Here, the peak acceleration was 100 g, the pulse length 2 ms and 4000 positive and 4000 negative pulses were applied. After all tests, the device 1 and the expanding rivet 2 could be assessed as in order.

[0032] Although only a few embodiments of the present invention have been shown and described, it is to be understood that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
