Tapping tee with simultaneously energized electrofusion elements

摘要

A tapping tee assembly 10 comprises an integrally moulded saddle 12, body 14 and socket 16. The saddle 12 is provided with a saddle-shaped electrofusion element mat 18 and the socket 16 is provided with a second electrofusion element 22. The electrofusion elements 22, 30 are connected by an integrated connector 26 and connecting pin 28 such that both electrofusion elements 22, 30 can be energised simultaneously using two electrical terminals 24,38. The connector 26 has a dovetail shaped extension (figures 5 and 10) into the bore of the socket 16, so that it can be held by a mound core during moulding. The connecting pin 28 may be inserted after moulding and may retain the electrofusion mat 18. This arrangement simplifies manufacture of a tapping tee with two simultaneously energized electrofusion elements.
