Erni has developed a broad portfolio of pre-alignment modules to enable the reliable connection to the backplane of complex plug-in cards with high pin-count hard-metric (HM) connectors. The innovative guiding solutions meet the need for precision connector mating combined with sufficient play between sub-rack guide rails and PCB cards. The pre-alignment modules can also be used for reliable coding and grounding issues.
The problem and the solution
Plug-in cards that comply with the CompactPCI standard (IEC 61076-4-101) are equipped with HM connectors. A 2 mm HM connector may have hundreds of contacts. The plug-in board connectors and related backplane connectors must mate precisely in order to avoid damage. However, there must be play between the cards and rails to avoid compression stress on the PCB. These pre-alignment modules from Erni consist of solid metal guides to ensure a secure and reliable connection.
The pre-alignment pin with fastening thread is fastened on the backplane and is available for PCB thicknesses of 2,5 to 6 mm, and 6 to 8 mm. The related guide bush is mounted on the daughter card using an M4 or M5 screw. PCB thickness for the daughter card can be 1,6 to 3,5 mm, or 3,5 to 5,5 mm.
The new guiding systems also offer several optional functions For example; there is a kit available with an integrated socket for HM 'coding' keys. Instead of using connector pins for coding, more pins are now available to carry signals. In addition, there are flattened pre-alignment pins designed to match their mating connector counterparts. Using an octagonal pattern, it will support eight additional coding options. Furthermore, electrical contacts can be tailored using pre-alignment pins for shielding or high-current handling (up to 40 A at 20°C).
