Patent ID: 6978754

Claim:
In combination, a manifold and a sensor, the manifold having a port for receiving the sensor, and external projections adjacent the port for aligning the sensor for insertion into the port and for preventing removal from the port, the port having diametrically opposed, radially inwardly projecting lugs, each lug having a ramped lading edge; the sensor having an insertion portion and a cable connection interface portion, the insertion portion and the cable connection interface portion being at right angles to one another; the insertion portion having a profile matching the port, and having diametrically opposed, radially outwardly projecting lugs, each lug having a ramped leading edge; whereby the insertion portion of the sensor is adapted to be inserted into the port of the manifold in an insertion position with the lugs out of alignment, and whereby the sensor is further adapted to be rotated so that the ramped portions of the lugs engage to draw the sensor into a seated position as the cable connection interface portion of the sensor abuts one of the external projections in the form of a rotation stop, and whereby the sensor is prevented from rotating back to the insertion position by another of the external projections in the form of an anti-rotation projection when a cable is connected to the cable connection interface portion.
