Abstract
Bridged bulkheads for a perforating gun assembly. The bridged bulkheads comprise a first bulkhead, a signal transmission pin residing within the first bulkhead, a second bulkhead, a detonator pin residing within the second bulkhead, and a bridge fixedly connecting and spacing apart the first bulkhead and the second bulkhead. Each of the bulkheads is fabricated from an electrically non-conductive material, while each of the pins is an electrically conductive pin. The bridge comprises a body connected to the first and second bulkheads. A signal transmission wire is connected to the signal transmission pin at the first end of the first bulkhead. At the same time, a detonator wire is connected to the detonator pin at the first end of the second bulkhead. The first bulkhead is over-molded to hold the signal transmission wire, while the second bulkhead is over-molded to securely hold the detonator wire.
