<p>An electric terminal such as a transformer bushing having a contact socket of conducting material is provided with a quench tube arranged in aligned substantially coaxial relation with the contact socket and constructed of an inner sleeve of arc extinguishing material and an outer sleeve of mechanically strong plastic material. Peripheral grooves are formed about the inner surface of the quench tube and resilient grommets are disposed in the grooves. An associated connector which may be of the elbow type is provided with a contact pin which includes a tubular element of conducting material to the end of which a stem of mechanically strong plastic material is affixed to support a hollow sleeve disposed thereabout and formed of arc extinguishing material and which is bevelled at its outer end to facilitate entry of the contact pin into and through the quench tube and into the contact socket so as to form a connection between the contact socket and the tubular element of conducting material.</p> |
