US12287182 - Initiator head with circuit board

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.

The patent describes an initiator head designed for firearms, featuring a circuit board housed within an insulated chamber to protect its electronics from shocks and vibrations. The manufacturing method involves injection molding a two-piece housing and filling the interior with insulating material to ensure electrical insulation and durability.

Claim 1

  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. 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.
