气体传感器
摘要：
本发明公开了一种气体传感器，其包括：传感器元件；第一绝缘体，传感器元件插入所述第一绝缘体中；第二绝缘体，设置在第一绝缘体的近端侧上，以覆盖传感器元件的近端侧；和接触构件，由第二绝缘体保持并夹合所述传感器元件。第一绝缘体的近端部分和第二绝缘体的远端部分沿着轴向彼此邻接。近端部分和远端部分的每个设有定位结构。所述定位结构被构造为限制第一和第二绝缘体之间沿着夹合方向以及与夹合方向和轴向垂直的正交方向的相对运动，沿着所述夹合方向，所述传感器元件被所述接触构件夹在中间。
摘要（英）：

The gas sensor includes a sensor element, a first insulator inside which the sensor element is inserted, a second insulator disposed on a proximal side of the first insulator so as to cover a proximal side of the sensor element, and a contact member held by the second insulator and sandwiching the sensor element. A proximal end portion of the first insulator and a distal end portion of the second insulator abut on each other in an axial direction. Each the proximal end portion and the distal end portion is provided with a positioning structure. The positioning structure is configured to restrict a relative movement between the first and second insulators in a sandwiching direction in which the sensor element is sandwiched by the contact member and in an orthogonal direction perpendicular to the sandwiching direction and in the axial direction.
