Wire Termination — Sta-Kon

Wire Termination & Insulation
Overview
Superior terminals for superior connections!
• Deep Internal Serrations
• Flat bottom box
• Electro-tin plating
• Center reinforced spring
detent for minimum

• Compound Spring Rails

Strands enter as a
homogeneous group and
compact tightly under
compression due to fully
brazed seam
Brazed or Ov erlapped Seam
A long barrel design is of little value unless it is one solid piece. That is why
Thomas & Betts brazes the seam on our vinyl-insulated Sta-Kon
®
terminals
andoverlaps the seam on nylon-insulated terminals. Many competitive terminals
have butted seams. This means increased chances for wirestrand loss, poor
resistance, wire pullout, and electrical failure. If the installer doesn’t position
thetool exactly on the correct spot on the barrel, there’s likely going to be
animproper termination. The butted seam can also fold due to tool-applied
pressure piercing the terminals insulation from the inside out. With Thomas
& Betts’ brazed oroverlapped seam, the installer can crimp anywhere along the
barrel’s surface. This provides up to 2.5 times the tensile strength of a butted
seam terminal, guaranteeing proper electrical flow, void free.
Selective Annealing
Because of the mechanical strength of copper, an installer can
experience fatigue associated with repeated installations. For
this reason, Thomas & Betts puts its terminals through one
more step called selective annealing. This process leaves the
barrel soft enough to crimp and form around the wire. However,
we “cold form” the tongue during the manufacturing process so
it remains strong. This is done so the tongue can withstand repeated
bends and bolt tightening strain common in most electrical installations.
Many competitors attempt to accomplish similar goals by removing valuable
material or using a softer copper, which has lower conductivity. This
increases electrical resistance as well as the odds for shorting
and downtime.
A nti-Rotational Tongue s
This is a unique feature to the Thomas & Betts ring tongue terminal. This
design prevents terminal shorting by keeping the terminal secure in the
terminal block. The installer can place a greater number of terminals closer
together without worry.
Proper Identification
We identify all terminals with Thomas & Betts initials, T & B. We also
indicate wire and stud sizes. These markings are clearly visible on the
surface of the tongue, taking any guesswork out of replacing or reordering
additional parts. Our superior bright plating also assists in visibility.
All Sta-Kon
®
Terminals
are Deburred and Degreased
To ensure a Sta-Kon
®
terminal is properly plated and insulated, all our parts
are put through a process that cleans and smooths the terminal of any
manufacturing by-products — mainly grease, oils and sharp edges. Many
competitive products do not put their product through such rigorous finishing.
