HOUSING CONNECTION ELEMENT

A housing connection element (10) for a housing of an exhaust gas treatment assembly unit of an exhaust system, especially for an internal combustion engine, includes a first housing part (16) with anessentially cylindrical first connection area (18) for connection to a circumferential wall (14) of a housing (12) of an exhaust gas treatment assembly unit. A tapered area (20) is adjacent to the first connection area (18). An annular, second housing part (40) is connected to the tapered area (20). A second connection area (46) is provided for connection to an exhaust gas-carrying component of an exhaust system. At least one sensor sleeve (48, 50) is in a sleeve receiving area (24) of the first housing part (16). The sleeve receiving area (24) is formed in the tapered area (20). 本发明涉及一种壳体连接元件(10)，其用于尤其是用于内燃机的排气设备的排气处理结构组合件的壳体，具有：第一壳体部件(16)，其包括用于连接到排气处理结构组合件的壳体(12)的周边壁(14)上的基本上圆柱形的第一连接区域(18)和连接到第一连接区域(18)上的变细区域(20)；连接到变细区域(20)上的环状的第二壳体部件(40)，所述第二壳体部件包括第二连接区域(46)，以用于连接到排气设备的排气导向构件上，以及在第一壳体部件(16)的在变细区域(20)中构成的衬套接纳区
