Screw connection, double deck, enlarged clamping area

https://wecoconnectors.com/wp-content/uploads/Images/978-EN-R.JPG

DESCRIPTION

The PCB connector 978-EN, a two-tier version with larger terminal space and a pitch of 5 mm is available in 4- to 24-pole design. This connector is a combination of the 978-HEN with the 978 version. The rear latching hook on the 978 series locks both terminals to one unit. This configuration allows application-specific locking combinations. The wire protector of the “DS”-version reliably prevents damage to multi-wire flexible conductors by the turning screw.
