Oxygen sensor
First Claim
1. An oxygen sensor including an elongate planar oxygen sensing element having a first longitudinal end and a second longitudinal end, wherein an oxygen detecting portion is adjacent to said first longitudinal end, said detecting portion being exposed to a measurement gas to determine an oxygen concentration of said measurement gas, said sensing element being electrically connected to at least one external device through at least one conductor member, wherein the improvement comprises:
- a protective covering having a first longitudinal end and a second longitudinal end, said protective covering accommodating therein said sensing element;
a rubber plug having a first end and a second end, whereby said second end is press-fitted into said first longitudinal end of said protective covering, said at least one conductor member extending through said rubber plug;
an electrical insulating member disposed between and retained by said second longitudinal end of said sensing element and said second end of said rubber plug;
electrical terminal means formed on said sensing element, adjacent to said second longitudinal end thereof, said electrical terminal means including at least one pair of electrical contacts disposed in said electrical insulating member; and
connector means disposed adjacent to said electrical terminal means, and including connectors which are electrically connected to said conductor members and are fixedly supported in said electrical insulating member, said connectors being held in direct electrical contact with said at least one pair of electrical contacts.

Abstract
An oxygen sensor including an elongate planar oxygen sensing element which has an oxygen detecting portion adjacent to one longitudinal end thereof. The detecting portion is exposed to a measurement gas to determine an oxygen concentration of the measurement gas. The sensing element is electrically connected to at least one external device through conductor members. An electrical terminal portion is formed on the sensing element, adjacent to the other longitudinal end thereof. The terminal portion has at least one pair of electrical contacts which are disposed adjacent to corresponding connectors for direct contact therewith.
