Patent number: 11952872Abstract: A detonator positioning device for use with a detonator in a perforating gun assembly is described. The detonator positioning device may be configured for electrically contactably forming an electrical connection within the perforating gun housing by contact. The detonator positioning device may include a body having a first end, a second end, and a central bore extending between the first and second ends. The central bore may be adapted for receiving one or more electrically contactable components of a detonator. The detonator positioning device can align at least one of the one or more electrically contactable components to form an electrical connection with a bulkhead assembly.Type: GrantFiled: September 23, 2022Date of Patent: April 9, 2024Assignee: DynaEnergetics Europe GmbHInventors: Christian Eitschberger, Gernot Uwe Burmeister, Thomas Keller Bradfield, Frank Haron Preiss, Thilo Scharf, Liam McNelis
