Abstract
A gas sensor includes, in a single housing section, a substrate mounting surface 31 mounted with a substrate including a light emitter and a light receiver and a mirror section including plural reflectors. Then, in the housing section, all of the plural reflectors are integrally molded on an inner surface of the housing section to multiple reflect light emitted from the light emitter and cause the light to enter the light receiver in an opposing direction of one side and the other side in an extension direction of the substrate mounting surface.
Claims6
A gas cell housing molding mold for injection molding, with resin material, a gas cell housing comprising a mirror section including a plurality of reflectors arranged to multiple reflect light emitted from a light emitter and cause the light to enter a light receiver in an opposing direction of one side and an other side of a substrate mounting surface with respect to the substrate mounting surface mounted with a substrate including the light emitter and the light receiver,
- the gas cell housing molding mold being configured to integrally mold all of the plurality of reflectors on an inner surface of the single gas cell housing to be molded by setting mutual pull-out directions of a lower mold and an upper mold during mold release obliquely with respect to a direction perpendicular to an extension direction of the substrate mounting surface so that all of the plurality of reflectors have no undercut shape.
A gas cell housing for a gas sensor comprising, in a single housing section, a substrate mounting surface mounted with a substrate including a light emitter and a light receiver and a mirror section including a plurality of reflectors,
- wherein in the housing section, all of the plurality of reflectors are integrally molded on an inner surface of the housing section to multiple reflect light emitted from the light emitter and cause the light to enter the light receiver in an opposing direction of one side and an other side in an extension direction of the substrate mounting surface.
