Abstract: A sensor includes a detection element; a plurality of terminal members, each of the terminal members including an elongated frame body portion extending along the axial direction, an element contact portion in elastic contact with an electrode terminal, and a folded portion connecting the frame body portion and the element contact portion; and a separator. The element contact portion of each of the terminal members has a turning portion which turns inward with respect to the width direction between the folded portion and a contact portion in contact with an electrode terminal. In those two of the terminal members which are adjacent to each other along the width direction, the distance along the width direction between the contact portions is smaller than the distance along the width direction between the frame body portions.

Abstract: A gas sensor including a plate-shaped sensor element having an electrode pad on an outer surface of the sensor element on a rear end side thereof, and a metal terminal member electrically connected to the electrode pad. The metal terminal member includes a body portion and an element abutting portion extending from the body portion and bent toward the electrode pad. A portion of the element abutting portion is in contact with the electrode pad in a state in which the element abutting portion is elastically deflected. The element abutting portion has a flat main surface facing the sensor element, and a sloping surface provided on at least one of end portions in a width direction of the metal terminal member. The sloping surface is connected to the main surface and extends toward an opposite side in a thickness direction of the element abutting portion.

Abstract: A gas sensor includes a sensor element, metal terminals, a tubular separator that holds the metal terminals, lead wires connected to rear ends of the metal terminals, and an elastic member that holds the lead wires extending rearward from the separator. Each metal terminal includes a forward end portion electrically connected to an electrode portion, a central portion, and a lead wire connection portion. The forward end portion or the central portion is held by the separator. The central portion and the lead wire connection portion are connected to each other through a neck portion. The rearward-facing rearmost surface of the central portion is engaged with a forward-facing surface of the separator, and the circumferential length of a first connection portion between the central portion and the neck portion is longer than the circumferential length of a second connection portion between the lead wire connection portion and the neck portion.

Abstract: An insulating separator of a gas sensor is formed to be dividable into a forward separator having a terminal disposition hole, and a rear separator having four terminal disposition holes. The insulating separator has a ventilation path formed between the forward separator and the rear separator. As a result, moisture and the like which enter the insulating separator from a forward side of the forward separator through the terminal disposition hole can be discharged outward of the insulating separator through the ventilation path. As a result, corrosion of metal terminals caused by entry of moisture can be reduced, whereby transmission of a sensor signal and application of current or voltage through the metal terminals can be appropriately implemented.

Abstract: A gas sensor is provided with a metal shell protecting member formed of a material superior in heat resistance to a metal shell, whereby a high-temperature measurement target (exhaust gas) is prevented from being in direct contact with a region, of a protector internal region of the metal shell, on the front side relative to a protector opposing surface. That is, in the gas sensor, it is possible to suppress corrosion, due to high temperature, of a region, of the protector internal region of the metal shell, on the front side relative to the protector opposing surface (an inner surface and a front end surface of a protector fixing portion), while the metal shell is formed of a material (SUS430) that can be subjected to working (crimping or the like) accompanied with deformation. Therefore, heat resistance of the entire sensor can be improved.
