SENSOR

摘要

A sensor includes a detector element, a connection terminal, and a separator. The contacting portion is in contact with a conductive member so as to overlap the conductive member in a thickness direction, which is a direction of thickness of the detector element between the principal surfaces. The separator includes an element accommodation space that accommodates a portion of an element contact portion and an element back portion, and a partition wall that separates the element accommodation space from a terminal accommodation space that accommodates the contacting portion and a portion of the conductive member and that is adjacent to the element accommodation space in the thickness direction. A frame main body is disposed in an element-side region, which is a region on an element-accommodation-space side in the thickness direction in a region obtained by extending the terminal accommodation space toward the front side in the axial direction.

主权项

1. A sensor comprising:
a detector element that extends in an axial direction and has a shape of a plate having two opposing principal surfaces, the detector element including a detection portion at a front side in the axial direction and an element back portion at a back side in the axial direction, the detection portion detecting a specific gas component contained in measurement target gas, the element back portion having an electrical pad formed on at least one of the two principal surfaces; a connection terminal which includes an oblong frame main body that extends in the axial direction, an element contact portion that is bent at a front end portion of the frame main body so as to extend toward the detector element and toward the back side and that is in elastic contact with the electrical pad, and a contacting portion that extends from a back end portion of the frame main body toward the back side and that is in contact with a conductive member that is electrically connected to an external circuit; and a separator that accommodates at least a portion of the connection terminal and at least a portion of the element back portion, wherein the contacting portion is in contact with the conductive member so as to overlap the conductive member in a thickness direction, which is a direction of thickness of the detector element between the principal surfaces, wherein the separator includes a partition wall that separates an element accommodation space and a terminal accommodation space from each other, the element accommodation space accommodating a portion of the element contact portion and the element back portion, the terminal accommodation space accommodating the contacting portion and a portion of the conductive member and being adjacent to the element accommodation space in the thickness direction, and wherein the frame main body is disposed in an element-side region, which is a region on an element-accommodation-space side in the thickness direction in a region obtained by extending the terminal accommodation space toward the front side in the axial direction.
