Electrical connection interface

Abstract

The invention discloses an electrical connection interface, and the interface comprises an active interface part which comprises a flange connection body and is provided with an accommodation space, aconnection flange located on a first surface, and a connection bottom surface located on a second surface; and also comprises a rotor adapter, an electric connector male end, a rotor, a nut, a floating device, a hollow screw, a shell and a ultrasonic motor arranged in the accommodating space; the ultrasonic motor is arranged on the first surface, the rotor adapter sleeves the first end of the male end of the electric connector and is attached to the ultrasonic motor, and the rotor is fixed on the rotor adapter; the nut sleeves the male end of the electric connector and is clamped in the rotoradapter, and the nut is radially supported and axially limited in the shell through an angular contact ball bearing pair; the floating device is placed in the hollow screw and is fixedly connected with the inner wall of the hollow screw, and the hollow screw sleeves the second end of the electric connector male end through an internal thread of the floating device; and the ultrasonic motor drivesthe rotor adapter and the rotor to rotate and drives the nut to rotate.

Description

technical field [0001] The embodiment of the present application relates to the field of satellite navigation, and relates to but not limited to an active electrical connection interface and a passive electrical connection interface. Background technique [0002] Limited by the constraints of carrying capacity, large-scale space facilities need to be launched into orbit in stages, and constructed by space robots on orbit. In order to reduce the complexity and operational difficulty of on-orbit construction and improve the efficiency of on-orbit construction, large-scale space facilities will adopt modular design technology. During the process of on-orbit construction and maintenance of space facilities, standardized connection interfaces will be used between modules. , can realize the free combination and expansion of each functional compartment or module. Standardized connection interfaces help to realize the modular design and multi-mission application of new space vehicl...

AI Technical Summary

Problems solved by technology

Some electrical connection interfaces provide insufficient connection force, resulting in improper connection, which makes the electrical connector unable to work normally; some electrical connection interfaces are tightened too hard after the connection is in place, resulting in the connection being stuck or even component damage, and the electrical connection cannot be guaranteed. Stable and reliable interface
