• the invention is directed to an outside door handle specified in the preamble of claim 1, where the outside door handle has a two-part housing.
• This housing consists of a handle body, which serves in the case of installation both for attaching the outside door handle to the door and for opening a lock provided on the door.
• the other part of the housing is a handle cover. Between the handle cover and the handle body creates a cavity which serves to receive a container.
• the invention has for its object to develop a door outside handle mentioned in the preamble of claim 1, which eliminates this problem. This is achieved by the measures specified in claim 1, which have the following special significance.
• an elastic potting compound is used, in which the sensor and / or at least some of the sensor operation serving electrical and / or electronic components are embedded.
• This potting compound creates an elastic surface on at least one end of the container, the is pressed in the case of installation against the inner surface of the housing cover or the housing body. In this contact pressure, the end piece of the container is deformed and is a sealing means, which prevents ingress of liquid between the container surface and the housing inner surface. Therefore, the functionality of the sensors is no longer impaired by the fluids entering them.
• the design according to the invention is particularly significant in the case of capacitive sensors which generate an electric field.
• the potting compound of the container serves as a dielectric for the electric field. If penetrating liquids are prevented from entering this area according to the invention, they can not falsify the physical properties of the dielectric.
• Fig. 2a in an exploded view corresponding to FIG. 1 is a schematic cross-section through the components of the outside door handle according to the invention prior to assembly and

• the carrier is attached to the door or flap of a vehicle. This body end 11 is thus a bearing end and serves for the storage of the outside door handle on the door of the vehicle.
• the other body end 12 is formed as a boom and provided with an end hook 14 which engages behind an initial member of a lock not shown in the door or flap of the vehicle.
• the starting element is detected via the hook 14 and the lock is actuated.
• This second body end 12 is thus the operating end of the outside door handle.

• Fig. 2b shows the mounting case between the handle body 10 and the handle cover 20. Then grab the shell 15 and the counter shell 25 with their side walls 18, 28 into one another. Between the shell 15 and the counter shell 25, a cavity 21 is formed. The intermeshing side walls 18, 28 are interconnected.
• the compound can e.g. performed by snap fasteners 22, which consist in the present case of a locking projection 23 on the outside of the shell side wall 18 and as a detent recess 24 on the inside of the counter-shell side wall 28.
• screwing means could be used.
• the cavity 21 receives in the case of installation on a special container 30 which is electrically connected via various electrical signal and operating lines 33 with corresponding control devices and / or with a power source.

• the container 30 includes two electrodes 31, 32 belonging to two different capacitive sensors.
• the one sensor 31 serves to lock the lock, while the other sensor 32 provides for the unlocking of the lock.
• the two sensors 31, 32 respond when, for the purpose of actuating the outside door handle, the hand of an authorized person approaches the first or the second electrode 31, 32 of the two sensors.
• the two electrodes 31, 32 are embedded in a potting compound 35, which is emphasized by dot-hatching and which has an elastically yielding design.
• this potting compound 35 can also be integrated to operate the two sensors 31, 32 serving electronic and electrical components.
• FIG. 2 b shows the installation case of the two housing shells 10, 20, which exert a pressure, illustrated by force arrows 41, on the container 30 located in the cavity 21.
• the elastic container end piece 40 of FIG. 2a is deformed in accordance with the pressure forces 41 in the sense of the form 40 'shown in FIG. 2b. The result is that the container surface 36 is pressed against the inner surface 29 of the housing cover 20.
• the container end piece 40 is due to its deformation 40 'a sealant.
• This sealing means 40 'prevents penetration of any liquid in the cavity 21 between the container surface 36 and the housing inner surface 29.

• An analogous sealing effect could, if necessary, also on the opposite container surface 37 with respect to the handle body inner surface 19 done.
• Such Anpresszonen 47 can therefore be generated simultaneously on several surface sides of the container.
• there are special positioning means 44 which ensure a defined position of the container 30 in the cavity 21.
• the positioning means 44 are in the illustrated embodiment of a projection 42 on the inwardly 26 facing container surface 37 on the one hand and from a complementary recess 43 on the outwardly facing inner surface 19 of the handle body 10 on the other.

In the present case, it would be possible to view the projection 42 with its protruding remainder 49 projecting from the opposite recess 43 as a "spacer" for the container 30 in the cavity 21.
