C&K Connector Specification CS FR022, amendment to the ESCC Generic Specification n° 3401, for low cost products manufactured :
- in the same ESA qualified site
- through the same manufacturing and control processes
- with the same piece parts
- with lighter controls, documentation and traceability
Applications : Engineering models, ground equipments, testing, some flight equipments (no need for high requirements).
The connectors and accessories, supplied according to these 2 quality levels, are totally compatible, interchangeable, and intermateable, as they are
manufactured with the same piece parts (except the cables), in the same ESA qualified site.

Contact Design

Wire crimp
The high-performance and reliable contact characteristics are obtained by the Micropin
TM
contact system.
The flexible "twist-pin" spring contact consists of 7 strands of 0,127 (.005) diameter beryllium copper wire helically wound around a core of 3 strands
0,09 (.0035) diameter soft copper wire.
This wire bundle is crimped into a sleeve at one end. The other end is terminated with a hemispherically shaped weld.
The wire bundle is compressed to create a bulge with a diameter slightly larger than the socket inside diameter.
The pin elongates and twists when it enters the socket. Electrical contact is maintained along 7 spiral lines.
The socket is a precision-made tube with a chamfered lead-in.
Normal mating conditions
Severe misalignment
Twist-pin contacts will mate even under severe misalignment.
The flexible twist-pin is recessed into the insulator and the rigid socket is exposed, reversing the traditional positions of pin and socket.
During mating, the socket is guided into the pin insulator by the lead-in chamfer.
The pin is kept from flexing beyond the socket capture radius by the walls of the cavity.
The hemispherical weld of controlled radius at the tip of the pin combines with the lead-in chamfers of the socket contact and the pin insulator to
cam the pin into alignment.
By controlling the welding process and the dimensions of the socket contact and the insulators, it is impossible for the recessed pin to escape the
socket capture radius.
