Title:
ガスセンサ
Document Type and Number:
Japanese Patent JP6724772
Kind Code:
B2
Abstract:
A gas sensor is provided which includes a sensor device, a plurality of contact springs, an insulator, a plurality of connecting terminals, and a lead cover. The insulator has an end surface which faces the connecting terminals and also includes as many protrusions as the contact springs. The insulator also has formed therein holding holes in which the contact springs are disposed. Each of the protrusions has formed therein a through-hole which communicates between an end surface of the protrusion and one of the holding holes. The through-holes are discrete from each other and formed one in each of the protrusions. This minimizes a risk of occurrence of leakage current between the contact springs or the connecting terminals arising from dew condensation and ensures a high degree of measurement accuracy of the gas sensor.
