Interconnect
|
Interconnection remains a fast-growing segment across the electronics
industry, with product developments addressing applications from
datacomms and wireless, to automotive and lighting.
Handheld devices remain a key market served with enhancements
from interconnect suppliers. For
example, the CCM01-03 series from
C&K Components offers a slim-line
product designed with a number
of added features such as an
integrated IP-54 switch and inlaid
contact finish to extend card lifetime
(page 080626). AVX also offers an
excellent SIM connector with push-push
locking and a ruggedised
design (page 080632).
Demand for greater transmission
and storage speeds has seen the
development interconnect products
supporting increased bandwidth,
such as Tyco Electronics’ MultiGig
family which supports 10Gbits/s MP
fibre-optic transmissions (page 080627).

Perhaps one of the largest and most interesting areas of growth is the
lighting market. Many of the interconnect developments for LED lighting
are designed to facilitate easy installation. A prime example of this is the
Tyco Poke-in connector, a surface-mount device allowing for high-volume
automated insertion. Similarly, AVX’s
9175-9177 series offers the same
functionality as the Tyco device but in
a variety of wire gauges, as well as
offering two- and three-way
configurations (page 080625). Mill-Max
has also developed a pluggable
gold standard receptacle providing
a reliable electrical connection as
well as supporting easy field-based
upgrades (page 080629).
The introduction of low-power
high-brightness LEDs has provided
some of the biggest challenges for
effective interconnect design. The
following pages highlight components
that have been designed to turn these
challenges into opportunities.

Poke-in connectors cut build time and cost for LED lighting
For designers building lighting modules,
PCB-based LED strings, and control units
for low-voltage lighting systems, surface-mount
Poke-In connectors from Tyco
Electronics accelerate design and simplify
assembly.
The connectors are delivered in tape and reel,
and are optimised for high-speed automatic
placement by providing a flat upper surface
for dependable vacuum pick-up.
When mounted on the PCB, the connectors
allow electrical connection to the completed
lighting module by simply pushing the wire
into the connector’s receptacle. Many other
applications will also benefit from this easy
poke-in wire termination to the PCB.
The connectors incorporate several design
features to optimise performance in lighting
applications, including rounded corners to
minimise shadowing, and redundant surfacemounting
pads to prevent peeling in units
operated in harsh physical conditions. The
current rating of 4A per connector, when
operated up to 250V AC or 250V DC,
allows designers to specify poke-in
interconnects with the brightest lighting LEDs
currently available.
With the pads located on 4mm centres, the
connectors deliver a compact interconnection
solution. In addition, their suitability for side-toside
stacking allows designers to arrange light
sources closely for maximum benefits.
