IDCs take on powerful duties

AVX series 9177 IDC connectors handle up to 15A and are rated for use at up to 650V, suiting them for use in applications such as high-voltage inverters in the lighting industry and other high-performance industrial equipment.

Available as a single-contact version for separate power handling or in two- and three-way configurations, 9177 series connectors offer the user flexibility of placement on the PCB for single or multiple wires.

The devices are end-stackable for larger pin counts, providing even greater flexibility.

Before assembly, the part is surface mounted to the PCB then using the mass termination tools a range of stranded (14 to 20 AWG) wires can be inserted into the contact slot.

This process displaces the insulation and enables the individual conductors of the wire to form a homogeneous joint (IDC termination).

The shape of the moulding forms a restraint to the wire's insulation when fully inserted in the contact, thus strengthening the joint.

This process can eliminate the need for hand soldering, cable preparation and lidding.

Contact material is phosphor bronze and offers potential for retermination under certain conditions.

According to Malcolm Ankers, Marketing Development Engineer at AVX: "The 9177 series offers customers the ability to terminate individual wires to a single row of contacts using discrete wire IDC technology".
