ABSTRACT

This paper reviews the applications and the characteristic structure of D Subminiature connectors in assembly and integration process of spacecraft. The alignment control and the locking force control are the key factors determining the reliability of D-Sub connectors coupling. The qualification vibration test of a bracket with D-Sub connectors shows that 0.22 Nm can be set as the torque value for male screws of D-Sub connectors in assembly and integration process of spacecraft. Two kinds of torque wrenches are designed to meet the general locking force control of male screw of D-Sub connectors in assembly and integration process of spacecraft.
