ABSTRACT:
This lightning arrester includes (i) a tubular housing comprising a plurality of tubular sections disposed in telescoping aligned relationship to define an internal chamber and (ii) a stack of arrester elements located within this chamber. Locking means between adjacent telescoping sections holds the sections together in aligned relationship.
Each locking means between adjacent sections comprises radially-projecting lugs on a telescoping portion of one of the sections and generally L-shaped slots in a telescoping portion of the other of the sections. The lugs fit into the slots and are displaced into locking portions of the slots by twisting motion of one of the adjacent sections relative to the other.
In one embodiment, the housing sections are molded components of polymeric material and the lugs are also of polymeric material and are integral portions of the tubular housing on which the lugs are located.
