Universal contacts have pre-load and anti-lift features
A new series of universal contacts from ITT Electronic Components provide an electrical connection between a device and a PCB. Manufactured as a single-piece stamped part, incorporating pre-load and anti-lift features, these new SMT contacts have been designed to replace traditional interfaces where the contact is custom-designed into the component. The contacts can be used to connect a number of device components in any direction and configuration using the same interface, thereby significantly reducing qualification time. The 1.3mm version features what is claimed to be the lowest profile currently available on the market – and an even lower profile option, just 0.9mm in height, is in development.
The range of Universal Contacts is available in heights of 1.3mm (minimum pitch 1.35mm), 1.8mm (minimum pitch 1.25mm), 2.5mm (minimum pitch 1.35mm), 3.5mm and 4mm (both with minimum pitch of 1.45mm). 'Side wings' protect the active parts of the contact, preventing the contact from overstressing and potentially suffering damage. Domed contact points allow good hertz stress and low contact resistance. A 'solderwell' prevents solder wicking up the contact. The X-Y-Z movement ensures a robust connection between the contact and component assembly to provide resistance to shock and vibration loads.
Universal Contacts provide a standard interface across applications and platforms and are suitable for use in numerous applications such as handsets (eg I/O connector, battery contact, SIM contact), laptops and computers (eg memory stick), home electronic devices and white goods (eg smoke detectors, alarm systems, home appliances), automotive (key fob), medical (CT scan equipment) and industrial (circuit breaker for GPS beacon). Universal Contacts are fully WEEE and RoHS compliant.
