Igniter assembly
An igniter assembly includes, an electric igniter and igniter collar, and a resin fixing the electric igniter into the igniter collar. The electric igniter has an igniter main body and a conductive pin which extends from the igniter main body. The igniter collar has a first through hole formed in the axial direction and at least one second through hole formed separately from the first through hole and being provided to the igniter collar. The electric igniter is fixed inside the first through hole by the resin, and the resin is also charged into the second through hole.
1. An igniter assembly, comprising:
an electric igniter having an igniter main body and a conductive pin extending from the igniter main body;
an igniter collar having an annular flat plate section protruding inwardly from an inner surface thereof; and
a resin fixing the electric igniter to the igniter collar,
wherein the igniter collar has,
a first through hole extending through the igniter collar including the annular flat plate section, and
a through groove formed in an inner peripheral surface of the annular flat plate section, and
wherein the electric igniter is fixed to the igniter collar by the resin inside the first through hole including the resin charged through through groove.
2. The igniter assembly according to claim 1 , wherein the first through hole of the igniter collar defines,
a first larger-diameter section space at one end of the igniter collar,
a second larger-diameter section space at an end of the igniter collar, opposite to the one end, where the conductive pin is positioned, and
an intermediate smaller-diameter section space between the first larger-diameter section space and the second larger-diameter section space, and
wherein the through groove is formed to extend between the first larger-diameter section space and the second larger-diameter section space.
3. The igniter assembly according to claim 2 , wherein the second larger-diameter section space is a space for inserting a connector, and a side surface covered with the resin has a concave section of the shape corresponding to a protrusion extending from the connector.
4. The igniter assembly according to claim 1 , wherein the igniter collar has a plurality of through grooves.
5. The igniter assembly according to claim 1 , wherein the through groove has a fan-shape.
6. An igniter assembly, comprising:
an electric igniter having an igniter main body and a conductive pin extending from the igniter main body;
an igniter collar having an annular flat plate section protruding inwardly from an inner surface thereof; and
a resin fixing the electric igniter to the igniter collar,
wherein the igniter collar has,
a first through hole extending through the igniter collar including the annular flat plate section, and
a passage formed in the annular flat plate section, and
wherein the electric igniter is fixed to the igniter collar by the resin inside the first through hole including the resin charged through the passage.
7. The igniter assembly according to claim 6 , wherein the passage is a through groove formed in an inner peripheral surface of the annular flat plate section.
