Metal holder with electrode pin, method of manufacturing the metal holder, and gas generator
First Claim
1. A metal holder with electrode pins, comprising:
- a metal holder and at least two electrode pins for allowing passage of electrical current, wherein each electrode pin is larger in diameter at its head portion than at its terminal portion;
plastic members arranged to contact the respective electrode pins so that the plastic members surround a part of the respective electrode pins circumferentially, andwherein through holes for the respective electrode pins to pass through the holder are formed in the holder, and the electrode pins are fixed to the holes via the plastic members, each hole including a diameter-reduction portion at a part thereof,wherein the plastic members are sandwiched between a part of the holder corresponding to the diameter-reduction portion and the respective electrode pins in the radial direction of the respective electrode pins.

Abstract
A metal holder, and a method of producing the same, with electrode pins suitably used for a gas generator having a structure that can prevent electrode pins from being burst forth easily even when the gas generator is brought into action under high temperature. The metal holder with electrode pins includes a metal holder and at least two electrode pins for allowing passage of electrical current. Each electrode pin is larger in diameter at its head portion than at its terminal portion. Plastic members are arranged to surround a part of the respective electrode pins circumferentially. Holes for the respective electrode pins to pass through the holder are formed in the holder, and the electrode pins are fixed to the holes via the plastic members, each hole having a diameter-reduction portion at a part thereof.

15. A method of producing a metal holder with electrode pins comprising:
-
after plastic members including holes are inserted in holes formed in the metal holder, electrode pins are inserted in the holes of the plastic members, and the metal holder is pressed at portions thereof around both opening portions of the holes in a depth direction thereof so that the plastic members can be partly reduced in diameter to fix the electrode pins. - View Dependent Claims (16, 17)

18. A method of producing a metal holder with electrode pins comprising:
-
after electrode pins are inserted in holes of plastic members including holes or after the plastic members and the electrode pins are integrally formed using an injection molding, the plastic members are inserted in the holes formed in the metal holder; and the metal holder is pressed at portions thereof around both opening portions of the holes in a depth direction thereof so that the plastic members can be partly reduced in diameter to fix the electrode pins. - View Dependent Claims (19, 20)
