Catalytic converter with mounting device for a hot exhaust gas oxygen sensor

1. A catalytic converter comprising:

a housing including an opening and a plurality of perforations;

upstream and downstream catalytic substrates positioned within the housing and separated by a mid-bed gap;

a ring having a gap in communication with the mid-bed gap, aligned with the opening in the housing and adapted to receive an exhaust sensor extending therethrough;

a plurality of ring embossments extending radially outwardly from the ring and operative to enable coupling of the ring to the housing at a corresponding perforation of the plurality of perforations; and

a layer of insulative material positioned between the ring and the housing between pairs of the embossments, each said embossment having a dimple extending from an outer surface of the embossment and shaped for receipt of at least a portion of the dimple by a corresponding one of the housing perforations.

2. The catalytic converter of claim 1 wherein the embossments are substantially devoid of sharp corners.

3. The catalytic converter of claim 1 wherein each dimple is welded to the housing at the corresponding housing perforation.
