Abstract
Abstract A female connector strip having contact springs which are interchangeably retained in a contact chamber. The contact chamber has a rectangular cross-section with each of the contact springs being of substantially U-shaped cross-section and having a box-shaped supporting body. The springs have contact points consisting of two ends of the limbs of the U-profile which, within the range of one face side of the supporting body are extended and folded towards the inside, the ends being directed towards each other. Further, the resilient ends of the contact reeds are touching each other.
