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.

O.D. Inner Insulation
Determine O.D. of inner conductor insulation
with measuring tool.
Inner Sleeve-Cat. GSB
Hard bronze inner sleeve is installed under braid.
Length 5/16”
Tin Plated as standard.
Inner sleeve
1. Use a measuring tool over the inner conductor insulation. Rotate wire to pick up high spots on cable that are non-symmetrical.
2. Add .005 to the diameter of the conductor insulation. Select inner sleeve with this I.D. or nearest larger I.D.
