Abstract
A bulkhead for transmitting detonation signals. The bulkhead is designed for use with a perforating gun assembly. The bulkhead comprises an elongated tubular body having a first end, a second end opposite the first end, and a bore extending from the first end to the second end. The bulkhead also includes a signal pin residing within the bore of the bulkhead. The signal pin also has a first end, and a second end opposite the first end. An electrically conductive wire is connected to the second end of the signal pin at the second end of the bulkhead. The bulkhead also comprises an end piece extending from the second end of the bulkhead. The end piece closely holds the conductive wire in place. Preferably, the end piece is over-molded to securely hold the detonator wire.
