Device for determining at least one parameter of a medium flowing in a conduit
US 7171865 B2
A device for determining at least one parameter of a medium which flows in a conduit has a fluid conduit part having a wall which forms a fluid conduit passage and has an insertion opening, a plug sensor having a sensor element, an insertion portion which is inserted through the insertion opening of the wall into the fluid conduit passage, an electrical connection portion which is not inserted into the fluid conduit passage, and a stop surface which abuts against a stop surface of the fluid conduit part, and mounting means for mounting the plug sensor on the fluid conduit part, the mounting means including a holding part which is pushed substantially perpendicular to an insertion direction of the plug sensor onto a connecting pipe of the fluid conduit part which surrounds the insertion opening, the holding part having at least one first portion abutting against a supporting surface of the connecting pipe and at least one second portion applying a pretensioning force to a securing surface of the plug sensor which faces away from the insertion portion of the plug sensor, so that a stop surface of the plug sensor abuts against the stop surface of the fluid conduit part.
The present invention relates to a device for determining at least one parameter of a medium which flows in a conduit.
Accordingly, it is an object of the present invention to provide a device for determining at least one parameter of a medium flowing in a conduit, which is a further improvement of the existing devices of this type.

FIG. 6 c is a view showing a section taken along the line A—A in FIG. 6 d;
FIG. 6 d is a view showing a section taken along the line B—B;
FIGS. 7 a–7 d are views showing a holding part of the device in accordance with the second embodiment;
FIG. 3 shows a fluid conduit part 40, which is arranged for example in a suction track of an internal combustion engine. The fluid conduit part 40 is formed for example as a cylindrical part with a cylindrical wall 41 surrounding a fluid conduit passage 42. During the operation air flows through the fluid conduit passage 42. The fluid conduit part can be provided with a not shown filter and for example mounted as an air filter box insert in the suction conduit. The wall 41 has an insertion opening 48 which is surrounded by a connecting pipe 43, for insertion of a plug sensor. The connecting pipe has a collar-shaped flange 44, with two slots 45 a, 45 b formed as guiding means for a holding part 20.
The securing part 10 is shown in FIGS. 1 a–1 d. It is formed for example as a synthetic plastic part and has a web 11, from which two pin-shaped engaging means 12, 12 b and an arresting hook 13 as well as a leg 14 extend in one direction. The securing part 10 is inserted in the insertion opening of the plug sensor 15 in the upper surface of the collar 44. The engaging means 12 a, 12 b are inserted in the throughgoing openings 46 and engage in the holding means 23 a, 23 b of the holding part 20. The arresting hook 13 and the leg 14 are inserted in an opening 49 of the collar until the arresting hook 13 engages a counter arresting means formed in the opening 49 as barbs. In the mounting position shown in FIGS. 4 a and 4 b the secured part 10 is non releasably connected with the connecting pipe 43 and engages with the lugs of the holding part, so that the latter can not be pulled out from the connecting pipe without destruction of the securing part.
A second embodiment of the invention device is shown in FIGS. 6 a–9 c. As can be seen from FIG. 8, the fluid conduit part 40 has a connecting pipe 43 provided with a collar-shaped flange 44. The flange has an upper flange surface 44 a, and a lower flame surface 44 b as guiding means for pushing on of a holding part 60. The inner wall of the connecting pipe 43, as in the first embodiment, has a stop surface 47 surrounding the insertion opening 48 for the plug sensor. The flange 44 is further provided with a lateral projection, in which a an opening 49 is formed. As a plug sensor, the plug sensor of the first embodiment shown in FIG. 5 can be inserted in the insertion opening 48.
The holding part 60 is shown in FIGS. 7 a–7 d and formed preferably as a punched bent part of sheet metal. The holding part has a U-shaped basic form with two straight legs 61 a, 61 b and a connecting web 69 which connects the legs. The legs 61 a, 61 b are bent perpendicularly from the connecting web 69 and are provided with hook-shaped holding means 65 a, 65 b on their ends 64 a, 64 b facing away from the connecting web 69. Each leg 61 a, 61 b is provided with at least one preferably perpendicularly bent first portion 62 a, 62 b on an upper side and with a preferably perpendicularly bent second portion 63 a, 63 b on the lower side. The first portions 62 a, 62 b can be preferably provided with sliding surfaces 68 a, 68 bb, which facilitate pushing of the holding part 60 onto the flange 44 of the connecting pipe 43. The second portions 63 a, 63 b of the legs 61 a, 61 b are provided with spring elements 67 b, which are formed of one piece with the second portions 63 a, 63 b by punching and bending.
A second embodiment of the securing part 30 is shown in FIGS. 6 a–6 d. The securing part 30 is formed as a synthetic plastic part and has a surface 68, form which a front wall 39 and a side wall 36 a, 36 b project perpendicularly. Slots 37 a, 37 b are provided in the side walls 36 a, 36 b, and the webs 32 a, 32 b are arranged in them. The webs 32 a, 32 b and an arresting hook 33 extend perpendicular to the surface 38 from the front wall 39. During insertion of the securing part 30 onto the flange 44 of the connecting pipe 43, the arresting hook 43 engages in the opening 39 and expands behind the counter arresting means 49 b arranged in the opening 49 as barbs, as shown in FIG. 8. Simultaneously, the webs 32 a, 32 b of the securing part 30 engage in the hook-shaped holding means 65 a, 65 b of the leg ends of the holding part 60, and thereby the holding part 60 is secured against pulling out from the flange 44. The front wall 39 of the securing part 30 covers the projection with the opening 39, so that a release of the arresting hook 33 is not possible. Advantageously, in this embodiment a dismounting of the plug sensor from the fluid conduit part is possible only by destruction of the securing part 30, to exclude a manipulation with the plug sensor.
