Detailed description of the invention
Fig. 1 consists essentially of a housing 2 and a piston element 3 with shown in axonometric chart, commonly known per se active cylinder 1.
Fig. 2 illustrates sensor 4 and sensor housing 5 thereof, and this sensor such as may be structured to stroke sensor. Being formed on this sensor housing 5, this projecting part outwardly and has a through hole 7 from a sidewall of this sensor housing 5 this projecting part one preferred single type of projecting part (Ansatzteil) 6. A male component is represented, for forming the electrical connection of and sensor 4 with 8.
Sensor housing 5 is so constituted, the corresponding of housing 2 that this sensor housing can be touching on described active cylinder in locking manner with one by contacting surface 9 shape is made to lean in contacting surface 10, wherein, at sensor housing 5 relative in the tram of the housing 2 of active cylinder 1, one pin-shaped rivet 11 act on the through hole 7 of the projecting part 6 through this sensor housing 5 and extend over this projecting part 6 deviate from the described side by contacting surface 10 so that the region stretched out can produce the device of heat, the heating of such as hot air device by means of one.At this, the region extending over described projecting part 6 of rivet 11 is melted in this wise so that the described region melted overlaps the marginal area of described through hole 7, for forming a fixed connection between the housing 2 of sensor housing 5 and active cylinder 1.
Fig. 4 illustrate described in be fixed in active cylinder 1 the side view of sensor housing 5.
It is pointed out that rivet 11 can also be arranged on sensor housing 5 and projecting part 6 can also be arranged on housing 2.
A device other, for making sensor housing 5 be connected is explained with the housing 2 of an active cylinder 1 below by way of Fig. 5-10. The details explained already in connection with Fig. 1-4 in Fig. 5-10 represents in an identical manner.
Particularly as shown in Figures 6 and 7, the housing 2 of active cylinder 1 has an elastic locking projection 13 on a wall components 12, and this locking is protruding preferably to be constituted with this wall components 12 single type ground and flexibly to exceed this wall components prominent towards the side by contacting surface 10 of housing 2 and be pressed into can resisting its elastic force in a dead slot 14 of wall components 12 when the corresponding power of applying. This locking projection 13 is connected with the marginal area of this dead slot 14 preferably by a film hinge.
According to Fig. 8 and 9, sensor housing 5 has a dead slot 15 at it in confined state towards the side of wall components 12, and when sensor housing 5 is placed on the housing 2 of active cylinder 1 with correct position, described locking projection 13 is embedded in this dead slot. This dead slot 15 has a locking component 16, this locking component from following effect from the locking projection 13 of the plane Elastic of described wall components 12 ground outlet swing, is used for being locked at sensor housing 5 housing 2 of active cylinder 1 in confined state or in fixed position.
Locking projection 13 preferably has one and is used as starting inclined plane, the face 17 extended relative to the longitudinal axis of housing 2, when sensor housing 5 is placed on the housing 2 of active cylinder 1, described locking component 16 acts on this face, described elastic locking projection 13 is pressed in described dead slot 14, until this locking component 16 arrives the bottom of locking projection 13 and this locking projection overlaps this locking component 16 ground, flexibly outlet swing from this dead slot 14.
It is pointed out that locking projection can also be arranged on sensor housing 5 and locking component is arranged on housing 2. The form of implementation of the replacement of this locking component and locking projection is also admissible.
