Single row barrier type terminal strip 2 ~ 24 poles , 9.5mm pitch
Description:
Barrier Strips is an interconnect which consists of a metal strip,
and connectors or screws, that allows for termination and
connection of wires. Barrier strip style terminal blocks are
available in three main categories: Dual Barrier, Tri-Barrier, and
Double Row. Each category of barrier strip is offered in several
industry standard centerline spacings, allowing you to choose from
high density to high current applications. Dual Barriers and
Tri-Barriers are very similar in that they are both offered with
hardware which allows them to be used in either PCB or panel mount
applications.
Barrier strips are designed for power applications and incorporate
a flip-open clear safety cover. Barriers contain stray or frayed
wire ends to prevent electrical shorts between positions on the
same block as well as adjacent components.
Why you need a terminal block?
• Screw terminals are low in cost when compared to other types of
connectors
• It can be readily designed into products for circuits carrying
currents of from a fraction of an ampere up to several hundred
amperes at low to moderate frequencies.
• The terminals easily can be re-used in the field, allowing for the
replacement of wires or equipment, generally with standard hand
tools.
• Screw terminals usually avoid the requirement for a specialized mating connector to be applied to the ends of wires.
Applications:
There are many applications that use terminal blocks & barrier
strips.
• Screw-type terminals are often used in order to connect a chassis
ground, like on a surge protector. Several public address systems
use them for speakers and other inputs and outputs. Screw terminals
are very widely used in electricity wiring, to connect switches,
and for connecting major appliances to plugs at home.
• Printed circuit board (PCB) terminal blocks are specially
designed with a copper alloy pin of suitable size and length and
can be inserted in printed circuit boards to be soldered to allow
electrical signals and current to flow to and from PCBs and
electrical equipment. Some designs provide features that allow the
flow of molten solder to endure a better connection between the
circuit traces of the board and the electrical equipment which is
meant to be controlled or fed appropriate power.
