<p>A gun system (30) in one arrangement includes a first carrier (18A or 18B) including a detonating cord (130 or 136) and a second carrier (18A or 18B) including a detonating cord (130 or 136). An adapter (20) couples the first and second carriers (18A, 18B), with the adapter (20) including an explosive (132 or 134) coupled to the detonating cord (130 or 136) of one of the first and second carriers (18A or 18B). The explosive (132 or 134) is positioned in a reduced housing portion (116) of the adapter (20). The reduced housing portion (116) of the adapter (20) has a first outer diameter less than an inner diameter of the first carrier (18A or 18B) to provide a predetermined annular space between the reduced adapter portion and the inner diameter of the first carrier (18A or 18B). At least one of the detonating cords (130 or 136) in the first and second carriers (18A, 18B) is attached to a retainer element (138 or 142), and the retainer element (138 or 142) is placed in close proximity to the explosive (132 or 134) to maintain an axial position of the detonating cord (130 or 136) to reduce separation between the detonating cord (130 or 136) and the explosive (132 or 134). In addition, the explosive (132 or 134) is placed some axial distance away from sensitive elements in the adapter (20), such as sealing elements (110A, 110B or 118A, 118B) and connector elements (114), to protect the sensitive elements from detonation of the explosive (132 or 134).</p> |
