Patent number: 11255247Abstract: A sensor including a sensor element, a metallic shell, a terminal fitting, a cylindrical case, lead wires, a connector portion, and a cylindrical heat shield tube. The heat shield tube includes a first tube and a second tube. The second tube is disposed on a distal end side of the first tube and covers an outer surface of the rear end side of the case, while providing an overlapping portion that overlaps the first tube. A rear end side of the first tube is adjacent to the connector portion. A total length T of the heat shield tube and a length S of the overlapping portion satisfy T/10?S?T/5. Further, a length L1 of the first tube and a length L2 of the second tube satisfy T/2?L2<L1.Type: GrantFiled: January 22, 2020Date of Patent: February 22, 2022Assignee: NGK SPARK PLUG CO., LTD.Inventors: Kouji Ogawa, Ayaka Ota, Hideya Inukai, Yasuhiro Ishiguro

Publication number: 20130036795Abstract: [Objective] To provide a gas sensor in which a filter member provided in an aerial communication hole adapted to introduce the air for exposing a reference electrode of a detection element to the air is reliably protected through simple configuration. [Means for Solution] A filter member 87 having air permeability and waterproofness is disposed in an aerial communication hole 91 formed in a grommet 9 disposed in a rear end portion 38 of a housing tube 3. The housing tube 3 has a vent portion 34 provided for ensuring aerial communication while protecting the filter member 87. The vent portion 34 is connected, by means of arm portions 33, to an end portion (an opening end 32) of a side wall 39 of the housing tube 3. The side wall 39 surrounds the circumference of the grommet 9. Since the arm portions 33 are disposed in respective grooves 93 of the grommet 9, the grommet 9 is positioned relative to the housing tube 3.Type: ApplicationFiled: August 8, 2011Publication date: February 14, 2013Applicant: NGK SPARK PLUG CO., LTD.Inventors: Naoki YAMADA, Takayoshi ATSUMI, Hideya INUKAI, Takeo MIZUI, Yoshiyasu FUJII
