Abstract: A housing connection includes a first housing defining a first housing compartment with a first set of threads defined circumferentially around the first housing. A second housing defines a second housing compartment therein. The second housing includes an engagement tab configured for engagement with the first housing. A retention nut defines a second set of threads circumferentially around the retention nut. The first and second sets of threads are engaged together and clamp the engagement tab of the second housing between the first housing and the retention nut ring.
