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

a specific series.)

Typical Application

Pictured below is a PC

board with barrier strips

and sockets wave soldered

to it.
