Single row barrier strip terminal block connector 2 ~ 24 poles ,
9.5mm pitch
Description:
Barrier terminal block with easy connection, These connectors are
available in all types of wires with 6.35-60mm pitch, with cover
and without cover.
Barrier terminal block is an interconnect device which consists of
short metal strips separated by a raised insulated "barrier" and
connectors or screws which allows for termination and wire
connection. Barrier terminal block is available in panel mount or
through hole mounting style.
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.

Installation:
Assembly of a screw connection requires some care in workmanship to
ensure proper removal of insulation, containment of all wire
strands, and the adequate tightening of the screw. If the wire
diameter is small in relation to the size of the screw, the wire
may be cut through by the over-tightening of the screw. This is
less likely to occur when a wire is clamped between two plates by
the action of a screw. Since wire strands may not be contained by
the screw head in a basic screw terminal, stranded wires may be
crimped into a ferrule to prevent the bridging of terminals; this
partly offsets the economy of a "bare" wire termination.
While wires may be crimped, they should not be heavily tinned with
solder prior to installation in a screw terminal, since the soft
metal will cold flow, resulting in a loose connection and possible
fire hazard. Screw connectors sometimes come loose if not done up
tightly enough at fitting time. Verifying adequate tightening
torque requires calibrated installation tools and proper training.
