PCB terminal block connector improves LED lighting reliability

New Products |
By Julien Happich

These new connectors support reliable long-term installation of LED Modules (assembled from LED arrays mounted on rigid and thermally conductive substrates for optimal heat dissipation) into a wide variety of applications e.g. High/Low Bay indoor lighting, street lighting, floodlighting and emergency lighting.

Applying har-flexicon with surface mount reflow soldering processes greatly simplifies LED Module PCB assembly. Connecting the conductors in lighting fixtures was formerly often done using hand soldering. This is often unreliable and prone to error when using printed circuit boards with a metal core, due to the high degree of heat dissipation. The optimised design of the har-flexicon connector SMT PCB hold-down’s ensure rugged solder-pad retention and supports reliable handling during equipment final integration.

PCB mounting design options include a horizontal male and a discrete wire push-in spring-cage terminal block part.  Both are made from high temperature LCP plastic which is completely ‘colour-stable’ after the SMT assembly process and UV resistant for long term installation. Pluggable female discrete wire push-in spring-cage cable connectors are also available. These have a strong but flexible locking-latch design which is highly damage resistant and ensures dependable mating. The product family comprises 2 and 3-way versions for stranded and solid conductors with cross-sections up to 0.75 mm², at a nominal current carrying capacity of 6A.
