AMP Micro-MaTch Miniature Connector System
Miniaturization and the trend towards higher density of electronic
functions on a substrate led to the introduction of smaller interconnec-
tion systems. The AMP Micro-MaTch connector family, with it’s contact
spacing of 1.27 mm, fully complies with the electronic packaging
requirements of today and the future. The system offers a range of
board and wire connectors, enabling a variety of wire-to-board and
board-to-board interconnections.The AMP Micro-MaTch contact concept
shown on this page is essentially different from other systems available.
By its design the traditional failure mode in tinplated connections,
fretting corrosion, is prevented. Due to an additional positioning spring
in the female part, relative movements caused by vibrations/thermal
expansion between male and female contacts are absorbed. By
preventing movements on the contact spot, a gas tight connection can
be guaranteed under all circumstances.
The contact spring is located in the board connector and not in the cable
connector, which is usually the case. The counter part, incorporated in the
cable connector, is a simple pin, either with an insulation displacement
section, suitable for the mass-termination of cable or with a kinked
solder leg to be soldered onto a PC Board.The separation of these two
basic functions of the contact system - contact force generation and
wire termination -, enables the independent optimization of both
functions and also leads to relatively simple contact shapes.
Because of their shapes contacts can be post-plated, leaving no bare
edges in the contact and wire slot area. The contact spring system
features an additional spring member - the positioning spring - which
compensates positional tolerances. In this way the contact spring can be
fully optimized for its basic function, so that the relatively high contact
force, required for tin plated contact systems, can be guaranteed
under all circumstances.
The Micro-MaTch contact spring system is absolutely
fretting corrosion proof by its design.
