Pluggable PCB terminals and headers
9 August 2006
Interconnection
Pluggable connection describes the method used to connect an external conductor to a PCB, via a terminal connector and header. The Wieland system is designed for frequent and ongoing equipment maintenance and system changes, as the pluggable terminal connector and PCB header are easily connected and disconnected. Prefabricated wiring arrangements can be easily interfaced to connect and enable the system.
Types range from 2-24 pole with different variants of terminals and headers allowing for horizontal, vertical and angled connection of wiring in relation to the PCB (for example; 35°) Pitch options are: 3,81/5,00/5,08/ 7,50/7,62/10,00/ 10,16 mm. Connection of single core and finely-stranded conductors up to 1,5 mm² and 2,5 mm².
Terminal connectors and headers can also incorporate additional fixing elements such as screw flanges, which helps prevent them being separated accidentally. This ensures secure electrical and mechanical connection, even under shock and vibration.
A coding system is available to prevent the connection of non-interchangeable components. The coding parts can be inserted into special slots in either or both the terminal connector and header. The coding does not affect number of available poles. Coding is possible with a minimum of four poles.
The plug in system is simple to maintain and screw termination is by means of rising cage clamp for security. Quality standard is in accordance with DIN ISO 9001.
