Embodiment Construction

[0011] like figure 1 As shown, the spacesuit electric umbilical cord of the present invention includes three sections of electric umbilical cords, wherein the first section of electric umbilical cord is mainly connected with the spacesuit for clothing, and can be designed to be 1-1.5m; the second section of electric umbilical cord is electrically connected The electrical umbilical cord for appliances is mainly connected to the electrical umbilical cord of clothing and the electrical umbilical cord of the spacecraft. It can be designed as 5-10m according to the needs. 0.5-1m. The three electric umbilicals are connected to the space suit and the cabin equipment respectively after docking. Each electric umbilical is laid with cables and steel cables. Both ends of each electric umbilical are composed of electrical connectors and mechanical connection mechanisms. The electrical connections at both ends The device is used to connect the cables, and the mechanical connection mechani...

Abstract

The invention discloses a method for sealing an electric umbilical cable and an electric connector of a space suit. Firstly, the wires in the cable bundle are welded on the pins of the electric connector, and then silicon rubber is used to seal the connection between the wires and the electric connector. Potting to form the first sealing layer, after the first sealing layer, epoxy resin glue is used to potting to form the second sealing layer, after the second sealing layer, silicon rubber is used to seal again to form the third sealing layer, the reinforcement in the cable The core lays within the second and third sealing layers. The invention uses different potting materials to pot the electrical connector in three layers, wherein the first layer and the third layer are made of silicon rubber, and the second layer is potted with epoxy resin glue, which effectively solves the problem of anti-bonding of the electric connector. The problems of exposure and easy wear of the wires are eliminated. At the same time, a reinforcing core is laid in the epoxy resin potting material, so that the wires and solder joints are not affected by external forces after the steel cable is laid, thereby improving the reliability of the cable.

Description

technical field [0001] The invention relates to a sealing method for cables and electrical connectors, in particular to a sealing method for spacesuit electric umbilical cables and electric connectors, and belongs to the technical field of spacesuit design. Background technique [0002] The electric umbilical cable is used to connect the cables of the extravehicular spacesuit and the on-board equipment to realize on-board power supply, telemetry and communication. It is used in the preparation of the airlock, the activities of the wired way out of the cabin and the detection after returning to the airlock. like figure 1 As shown, the electric umbilical cord includes 1.2m clothing electric umbilical cord, 8m electric umbilical cord, and 0.5m electric umbilical cord. After docking, the three electric umbilical cords are respectively connected with the spacesuit and cabin equipment, and each electric umbilical cord is laid with steel cables. It is used to connect the astronaut...
