Abstract

An assembly for mounting a sensor to an exhaust flow system comprising a locking member defining a through hole and a body element engageable with the locking member. The locking member desirably defines a pair of slots, and the body element desirably includes a pair of tabs. The body element is receivable within the hole defined by the locking member and the tabs are receivable within the slots defined by the locking member. The body element is rotatable relative to the locking member from an unlocked position in which the tabs are aligned with the slots to a locked position to lock the body element to the locking member. The locking member may be in the form of a ring and an exhaust pipe, with the ring being welded to the exhaust pipe. The body element may be in the form of a sensor and a sensor mount disposed about the sensor. Each tab includes an engaging surface and the ring includes a pair of bearing surfaces to engage and act upon the engaging surfaces. Each bearing surface may include a camming surface for camming the body element during rotation of the body element, and may define a void for receiving the engaging surface of one of the tabs when the body element is rotated to the locked position. Each bearing surface desirably includes a barrier wall for maintaining the engaging surface within the void when the body element is rotated to the locked position.
