Abstract
Official abstract text for this publication.
An initiator head includes a housing piece defining an interior chamber, a circuit board supported in the interior chamber, a line-in terminal coupled to the circuit board, and insulating material filling the interior chamber and covering a top surface of the circuit board for absorbing shocks or vibrations and electrically insulating electronics of the circuit board.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing an initiator head, the method comprising: injection molding a first housing piece that defines an interior chamber, a circuit board being positioned within the interior chamber; coupling a second housing piece to the first housing piece to cover the interior chamber; and filling the interior chamber with an insulating material thereby covering electronics of the circuit board with the insulating material; wherein the second housing piece is coupled to the first housing piece before the interior chamber is filled with the insulating material; and filling the interior chamber comprises injecting the insulating material into the interior chamber via a hole defined through the second housing piece. 2. The method according to claim 1 , wherein the insulating material is a second housing piece having a definite shape, and filling the interior chamber includes press fitting the second housing piece into the interior chamber. 3. The method according to claim 1 , wherein the insulating material is a second housing piece, and filling the interior chamber includes injection molding the second housing piece into the interior chamber.
