摘要： A gas sensor includes a sensor element having electrode pads, metal terminal members connected to the respective electrode pads, separators, and lead wires connected to the rear ends of the metal terminal members. Each metal terminal member has a forward locking portion and a rear locking portion provided at the forward and rear ends, respectively. The separator is composed of a forward separator and a rear separator connected to each other. The forward separator includes a first locking portion having a rearward-facing surface, and the rear separator includes a second locking portion having a forward-facing surface. The metal terminal member is held between the forward separator and the rear separator in a state in which the forward locking portion is in locking engagement with the rearward-facing surface and the rear locking portion is in locking engagement with the forward-facing surface.

摘要： 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.

摘要： In a circular cross section obtained by cutting a protector along a plane which is orthogonal to an axial direction and passes through gas introduction holes, the gas introduction holes are arranged asymmetrically in the circumferential direction of a circumferential wall of the protector. When the circular cross section is bisected into first and second divisional regions by a straight line which passes through the center of the circular cross section and does not pass through any gas introduction holes, the total opening area of gas introduction holes located in the first divisional region is smaller than the total opening area of gas introduction holes located in the second divisional region.

摘要： A gas sensor includes a sensor element having an electrode pad and a metal terminal member including a forward metal terminal member connected to the electrode pad, and a rear metal terminal member connected to the forward metal terminal member and a lead wire. The rear metal terminal member includes a forward end portion, a central portion, and a lead-wire connection portion. The forward end portion and the central portion are integrally connected through a first neck portion smaller in sectional area than the forward end portion and the central portion. The central portion and the lead-wire connection portion are integrally connected through a second neck portion smaller in sectional area than the central portion and the lead-wire connection portion. The first neck portion is greater in moment of inertia of area than the second neck portion.

摘要： A gas sensor includes a protective cover having a resin cylindrical cover portion at a rear end thereof, that can be airtightly attached to an attachment hole, and that can prevent a decrease in quality and a molding defect. A plurality of vertical ribs, which extend substantially parallel to an axis of a cylindrical cover portion, are formed on an outer peripheral surface of the cylindrical cover portion so that protrusions and recesses are provided in a circumferential direction. Due to the presence of the vertical ribs, as compared with an existing cylindrical cover portion that has a smooth outer peripheral surface without the vertical ribs, defects of the outer peripheral surface are not likely to occur in a molding process. Moreover, because slipping is not likely to occur when an operator holds and twists the cylindrical cover portion with his/her fingers, an attachment operation can be smoothly performed.

摘要： A gas sensor includes a gas sensor element for detecting the concentration of a specific gas in a gas under measurement, a tubular housing having an opening, a sealing member closing the opening, and a heat dissipating member having a rear end located at the same position or forward of the rear end of the housing. The heat dissipating member reduces heat transferred from the forward end side of the gas sensor to the sealing member and includes a connection portion connected to the housing, and a main portion extending rearward from the connection portion such that a gap is formed between the main portion and the housing. The main portion has heat dissipating openings for establishing communication between the gap and a space on the outer circumferential side of the heat dissipating member. The heat dissipating openings are formed on the rear end side of the main portion.

摘要： A gas sensor includes a sensing element that includes an electrode pad, a metal terminal, and a separator. The metal terminal includes a lead-wire-connecting portion, a main body, a protruding piece that protrudes from a front-end side, and an elastic portion connected to an end of the protruding piece and to the electrode pad. An area S1 of a first opposed surface of a primary surface facing an insertion hole of the separator is larger than an area S2 of a second opposed surface of a secondary surface facing the insertion hole, and a part of the second opposed surface contacts an inner circumferential surface of the separator forming the insertion hole, and the first opposed surface is separated from the inner circumferential surface, where surfaces of the main body and the protruding piece that are located opposite the elastic portion are the primary surface and the secondary surface.
