Abstract
A method of forming an initiator head assembly for an initiator is described. An initiator head assembly having particular application with a perforating gun assembly is also described. The initiator head assembly includes a body and an electrical contact component with the electrical contact component embedded therein. The initiator head assembly, with the embedded electrical contact component, is configured as a unitary component and holds a pressure differential across the top and bottom parts of the initiator head assembly.

A method of making an initiator head assembly, comprising:
- forming an electrical contact component comprising an electrically contactable line-in portion and an electrically contactable ground portion;
- and
- forming a body as a unitary component around the electrical contact component to seal the electrical contact component against pressure leakage across the body, wherein
- the body comprises a head extending from a base, and the head comprises a first surface, a second surface opposite the first surface and extending from the base, and an insulating portion extending between the first surface and the second surface.
A method of making an initiator head assembly, comprising:
- forming an electrical contact component comprising an electrically contactable line-in portion and an electrically contactable ground portion;
- and
- forming a body from a solid material, such that the body is configured to extend around the electrical contact component to seal the electrical contact component against pressure leakage across the body, wherein
- the body comprises a head extending from a base, and the head comprises a first surface, a second surface opposite the first surface and extending from the base, and an insulating portion extending between the first surface and the second surface.
A method of making a detonator assembly comprising an initiator head assembly, the method comprising:
- forming an electrical contact component comprising an electrically contactable line-in portion and an electrically contactable ground portion;
- forming a body as a unitary component around the electrical contact component to seal the electrical contact component against pressure leakage across the body, wherein the body comprises a head extending from a base, and the head comprises a first surface, a second surface, and an insulating portion extending between the first surface and the second surface;
- and
- arranging a portion of the base within an open end of a detonator shell, such that the ground portion is positioned to electrically contact a ground portion of the shell.
