Space navigation high-speed cable assembly assembling and connecting method

Abstract

The invention discloses a space navigation high-speed cable assembly assembling and connecting method. The method comprises the following steps of manufacturing a shielding braided sleeve pipe according to structural dimensions of a space navigation kilomega star stranding wire and an insulating module; performing crimping on the wire and a contact part and then mounting in the insulating module; mounting the wire and the insulating module into the shielding braided sleeve pipe; riveting and pressing a wire shielding braided layer and a grounding wire on the shielding braided sleeve pipe; mounting the shielding braided sleeve pipe into a shell, and crimping the grounding wire in a grounding groove; and mounting the wire into an electric connector, and then performing encapsulation and curing by encapsulation adhesive. By adoption of the method, the wire is riveted and pressed at one end of the shielding braided sleeve pipe while the other end is arranged on the insulating module in a sleeving manner and mounted in the shell, so that the problems of discontinuous shielding and relatively high crosstalk in the conventional assembling and connecting mode can be solved; and by virtue of the encapsulation adhesive, the shielding braided sleeve pipe and the electric connector can be cured, so that the optimal insulating effect of the cable assembly can be achieved, the application requirement of the space navigation environment can be satisfied, and the shortcomings of low transmission rate and relatively low stability of the conventional assembling and connecting mode can be overcome.

Description

technical field [0001] The invention relates to an assembly method for aerospace high-speed cable assemblies, especially suitable for TLK2711 high-speed cable assemblies, and belongs to the technical field of aerospace high-speed cable connections. Background technique [0002] Aerospace cable assemblies are an important part of spacecraft.
