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.
