Metal housing of an internal combustion engine exhaust gas senser having protective pipes |
摘要 |
An absolutely secure joining of the protective pipes to the housing is to be achieved during operation, in the case of a metal housing of an internal-combustion-engine exhaust gas sensor having two protective pipes attached thereto, the pipes being disposed coaxially one inside of the other and projecting outwardly from the housing; each of the pipes being made of the same kind of metal; at least the outer protective pipe being welded to the housing; and the pipes being radially set apart at least in their respective regions projecting from the housing. For this purpose, at least the inner pipe and the metal housing are joined to one another in a force-locked and form-locked manner in the axial direction of this protective pipe, via radially intermeshed projections, at least when the metal housing is in a closed state.
