Connector assembly with a blade connector

A connector assembly for electrically contacting a blade connector to a second connector, the connector assembly comprising:

• a blade connector, extending in a longitudinal direction, having:
• (a) a contact surface plane, and
• (b) at least one guiding element on the contact surface plane of the blade connector:
• (1) extending along a guiding direction basically perpendicular to the longitudinal direction along which the blade connector extends, and
• (2) is at least one of a rail, a rib, and a series of spot-like structures,
• (3) has an overall trapezoidal cross-sectional shape perpendicular to the guiding direction of the guiding element, and
• (4) protrudes from the contact surface plane perpendicular to the longitudinal direction along which the blade connector extends and the guiding direction along which the guiding element extends, and
• a second connector electrically connected to the blade connector in a mated state through the contact surface plane;
• and
• a mounting cage captively holding the blade connector and having at least one clamping device that presses the second connector onto the contact surface plane of the blade connector in the mated state.
