Liquid-condition detection sensor
First Claim
1. A liquid-condition detection sensor, at least a portion of which is to be immersed in a liquid to be measured, and which is adapted to detect a condition of the liquid to be measured, comprising:
- a sensor element, at least a portion of which is to be immersed in the liquid to be measured;
a terminal member fixedly attached to the sensor element;
an electrically conductive path member connected to the terminal member and electrically communicating with the sensor element via the terminal member;
a holder tube extending in a longitudinal direction of the sensor, directly or indirectly holding the sensor element at a distal end portion thereof, and surrounding at least a portion of the electrically conductive path member and at least a portion of the terminal member; and
a separator intervening between the terminal member and the holder tube and insulating the terminal member and the holder tube from one another.

Abstract
A liquid-condition detection sensor (1) including a sensor element (51), at least a portion of which contacts a urea aqueous solution; connection terminals (52) fixedly attached to the sensor element (51); connection cables (53) which electrically communicate with the concentration sensor element (51) via the connection terminals (52); an inner tube (42) which holds the concentration sensor element (51) at a distal end portion (421) by use of a holder member (55) and surrounds a portion of the connection cables (53) and the entire connection terminals (52); and a separator formed from a material having rubberlike elasticity (54) including a terminal-inner-tube-insulating portion (542) which intervenes between the connection terminals (52) and the inner tube (42) to thereby insulate the connection terminals (52) and the inner rube (42) from one another.
