Abstract
According to an aspect a bulkhead assembly is provided having particular application with a downhole tool, in particular for oil well drilling applications. The bulkhead assembly includes a bulkhead body and an electrical contact component disposed within the bulkhead body, wherein at least a portion of the electrical contact component is configured to pivot about its own axis, without compromising its ability to provide a pressure and fluid barrier. In an embodiment, a ground apparatus is provided to provide an electrical connection for at least one ground wire. The ground apparatus may be positionable on the bulkhead body of the bulkhead assembly. In an aspect, a downhole tool including the bulkhead assembly and ground apparatus is also generally described.
