Abstract
An end plate for a perforating gun assembly. The end plate has a first end defining a first face, and a second end opposite the first end defining a second face. A flange resides between the first face and the second face. The end plate has a first through-opening and a second through-opening. A first bulkhead resides in the first through-opening, and is configured to closely receive a signal transmission pin. A second bulkhead resides in the second through-opening and is configured to closely receive a detonator pin. The signal transmission pin transmits detonation signals through the end plate, while the detonator pin transmits detonation signals back up the wellbore and through the end plate. The end plate may also have an opening along the second face for receiving a ground pin.
