BUCHANAN Terminal Blocks
Barrier Strips – Overview
Two Types of Barrier Strips
and a Line of Sockets: Tri-Barrier
Three walls or barriers
surround each terminal
screw. The back wall
safeguards field wiring.
Dual-Barrier
Two walls or barriers are
molded on each side of the
terminal screw.
Sockets
Mounted directly to the PC
board, the Barrier Strip is
plugged into the socket.
The socket expedites field
maintenance. (Below, a
tri-barrier is about to be
mounted in a socket.)
Wire Clamp Screws
The lower surface and
edges of the clamping-
plates are carefully
designed to securely
clamp the wire—even
combinations of different
wire sizes—without
severing stranded wire.
Extra care has been taken
to produce these
components without burrs
on any critical clamping
surface or edges.
Resilient Plastic Barriers
Flexible thermoplastic
material for terminal blocks
was an especially important
feature at the time of its
introduction, since many
earlier blocks were molded
of more rigid, brittle
thermosetting plastic
compounds.
Wire-Ready Raised Screws
Wire-ready raised screws
are standard on
BUCHANAN terminal
blocks. No need to back off
the screw first. Just insert
the wire and drive down the
screw. Wire installation time
and effort are virtually cut in
half.
Integral Standoffs
Standoffs help rid your PCB
of any remaining corrosive
agents during rinsing
operations. Helps prevent
trapped solutions in the
immediate PC pin area.
Significantly reduces the
risk of postwave corrosion
problems.
Gas-Tight Connections
The acid-tin plating on our
terminals means more than
just improved shelf-life and
superior solderability. It is
to provide the very basis
for the heart of your wire
connections.
Quality Plating
Tyco Electronics
Corporation has been
known for its plating,
especially on the tin-plated
components, and has
maintained stringent plating
specifications to provide a
better performing, more
reliable product. (Terminals
meet or exceed Tyco
Electronics Specification
109-11-1.)
UL Recognition and CSA
Certification
Terminal blocks and
interconnect components
are Recognized under the
Component Recognition
Program of Underwriters
Laboratories Inc. and
Certified by Canadian
Standards Association.
(Consult individual sections
of this catalog for status of
aspecific series.)
Typical Application
Pictured below is a PC
board with barrier strips

Tri-Barrier blocks help
contain stray or frayed wire
ends. This helps prevent
electrical shorts — not only
between positions on the
same block, but also
between other components
immediately adjacent to the
block. With today’s high-
density PCB designs, this
has become an
increasingly important
feature.

0.4375” [11.1] Pitch, Series SSB7 (Continued)
LR25557 E63810
Contact Spacing Options:
.4375 in (7/16") Spacing
Extra thick barriers provide higher
voltage rating. Up to 27 ckts. (25
circuits for end mounted blocks)
Base Options:
Closed Base
Catalog Letter
Code: C. For
terminal junction-
blocks requiring
top connections
only. Useful in
applications
requiring single point circuit
terminations or circuit completion via
top mounted, single- and two-sided
quick-connects. Replace double-row
barrier strips.
Flat Base
Catalog Letter
Code: F. Lends
itself most readily
to applications
where direct top-
to-bottom feed-
through is required with no special
requirement for circuit isolation on the
bottom side. The most common
example of this is printed circuit
board mounting.
Raised Base
Catalog Letter Code R. Standoffs
between each circuit raise block
.030" above mounting surface to
allow flux and solvents to drain
during soldering operations.
Available only with 02 and 04 bottom
terminals.
Turret Base
Catalog Letter Code: T. Combines
top-to-bottom
feed-through
with bottom-side
circuit isolation
for panels up to
.126" thick. Turret
bases are available with the following
terminals: solder tail, quick connect,
machine wrap, extended circuit
board terminal, and right-angle.
Mounting Options:
End Position
Mounting
Catalog Letter
Codes: E, F, G
or M. Supplied
without contacts in end sections to
allow installer to mount blocks with
screws in end section holes. Base of
block will support mounting screws
(Codes F & M). Also available with
mounting inserts installed in end
mounting holes to raise mounting
screw heads to the level of other top
hardware (Codes E & G).
Without End Barriers
Catalog Letter Codes: F, G & H.
Facilitates mounting-screw access
when end sections are used for
mounting.
Direct Mounting
Catalog Letter Codes: P & H. SSBs
may be solder-mounted using the
bottom terminals themselves, as in
the case of printed circuit board
applications.
Direct mounting is also possible with
turret base models using press-on
retaining clips (Catalog No. L97, Part
Number 1437661-7) on turrets.
Terminal Style:
Solder Tail
Catalog Number
Code: 01. For
applications requiring
awrapped solder
connection.
Printed Circuit Pin
Catalog Number
Code: 02.
Designed specifically
for mounting on .063"
thick circuit board.
Special, readily
solderable plating permits good fillet
development in automated soldering
processes.
Non-Feed-Through
Catalog Number
Code: 03.
With closed base
option only.
Extended Printed
Circuit Pin
Catalog Number

Product Facts
nEnd-to-end mounting of USB
sockets maintain circuit
spacing: Two 12-circuit USB
sockets can mate with one
24-circuit SSB3 or RSB3.
nSecure mating with built-in
locking arms
This unique plug-in socket
line allows quick connection
of circuits simultaneously
without the use of tools.
They are designed to be
wave-soldered to a PC
board, after which the
connector is plugged into
the socket.

BUCHANAN Terminal Blocks
0.325" [8.26] Pitch, Series SSB3, Options
Base
Catalog Letter Code: F. Lends itself
most readily to applications where
direct top-to-bottom feed-through is
required with no special requirement
for circuit isolation on the bottom
side. The most common example of
this is printed circuit board mounting.
Mounting Options
End Position Mounting
Catalog Letter Code: M. Provides a
printed circuit board mounting option
with top-side wire entry.
End Position Mounting Without
Barriers
Catalog Letter Code: F. Facilitates
mounting-screw access when end
sections are used for mounting.
Direct Mounting:
Catalog Letter Code: P. SSBs may
be solder-mounted using the bottom
terminals themselves, as in the case
of printed circuit board applications.
Terminal Style:
Printed Circuit Pin:
Catalog Number Code: 02.
Designed specifically for mounting
on .063" thick circuit
board. Special,
readily solderable
plating permits good
fillet development in
automated soldering
processes.
Extended Printed
Circuit Pin:
Catalog Number
Code: 04. Useful
where extra length is
needed, as in thicker
printed circuit
boards or single-
wrap connections.
Top Hardware Options
Binding Head Screws
Catalog Number Code: 01. In most
applications, binding head screws
will provide excellent wire retention
because of exclusive wire locking
tabs. Screws are bright zinc and
chromate plated steel.
Captive Clamp
Catalog Number Code: 02.
For applications requiring
extra security, captive clamps under
the screw heads augment the locking
tabs on each contact. Screws have a
unique Phil-slot design accepting
either Phillips-head or straight
screwdriver. Code 02 screw is bright
zinc and chromate plated steel.
Quick Connects
Catalog Number Codes: 10 through
75. Acomplete selection of .187"
and .110" quick-connect blades are
available for connecting wire
terminated with female quick
connects. Single-and double-sided
types in flat, 45º and 90º angle bends
can be supplied. Material is brass
with tin plating. All blades supplied
with 01 screws. Various quick-
connects can be combined.
