Two-Piece Grounding Connectors for Shielded and Coaxial Cable A reliable method for grounding, terminating and insulating shielded and coaxial cable All-around hex compression is applied with a simple tool. The result: a permanent, compression joint. With or without grounding wire (insertable from front or back), reliable grounding of termination is done quickly, neatly, and accurately. The Thomas & Betts hex compression is a permanent method which has reliably connected literally hundreds of millions of installations in communications, aerospace, electronic, telephone, radio and TV. The termination is completed quickly, neatly, accurately … at a greatly reduced production cost. Installation Method 1. Slip outer sleeve over insulation jacket, after stripping. Trim braid to within 1/2” of insulation. 2. Fan braid by rotating center conductor and slip inner sleeve under braid. 3. Position inner sleeve to extend about 1/16” beyond braid. 4. Slip one No. 22 or No. 20 ground wire under outer sleeve (front or back), and slide outer sleeve over braid. For Daisy chain grounding, two ground wires can be accommodated by selecting the proper size outer sleeve. 5. Outer sleeve covers all exposed strands. 6. Compress in specified tool. (Tool will not release until full compression stroke is completed.) Warning: Never install on energized wire. 229 Two-Piece Grounding Connectors for Shielded and Coaxial Cable O.D.
