US12624618 - Detonation module

A detonation module for a perforation tool includes an end that may receive and couple to a ballistic transfer unit of the perforation tool, a detonator, a switch circuit electrically coupled to the detonator, an electrical contact electrically coupled to the switch circuit, and an electrically conductive, compressive member that may couple to the ballistic transfer unit of the perforation tool and form a compressive electrical connection between the electrical contact and the ballistic transfer unit. The electrical contact is disposed between the detonator and the electrically conductive, compressive member.

The patent describes a detonation module designed for use with a perforation tool, featuring a coupling end for a ballistic transfer unit, a detonator, and a switch circuit. It includes an electrical contact and a compressive member that ensures a secure electrical connection between the contact and the ballistic transfer unit.

Claim 1

1 . A detonation module for a perforation tool, the detonation module comprising: an end configured to receive and couple to a ballistic transfer unit of the perforation tool; a detonator; a switch circuit electrically coupled to the detonator; an electrical contact electrically coupled to the switch circuit; and an electrically conductive, compressive member configured to directly couple to the ballistic transfer unit of the perforation tool and form a compressive electrical connection between the electrical contact and the ballistic transfer unit, wherein the electrical contact is disposed between the detonator and the electrically conductive, compressive member. an end configured to receive and couple to a ballistic transfer unit of the perforation tool; a detonator; a switch circuit electrically coupled to the detonator; an electrical contact electrically coupled to the switch circuit; and an electrically conductive, compressive member configured to directly couple to the ballistic transfer unit of the perforation tool and form a compressive electrical connection between the electrical contact and the ballistic transfer unit, wherein the electrical contact is disposed between the detonator and the electrically conductive, compressive member.
