Problems solved by technology

[0010] (1) In order to prevent the tail wire of the anti-wave bushing from piercing the cable insulation layer (it has happened many times), usually it is necessary to end the shielding at about 5cm outside the cable, and deal with the tail wire so that the shielding cannot be continuous
For transmission cables with low frequency signals and relatively high sensitivity, this connection method cannot meet the requirements of shielding effectiveness
[0011] (2) Use the

Abstract

The invention relates to a cable connection with shielding continuity, which comprises a cable, a cable connector, a shielding layer ground wire, a connector tail clip, a copper cloth, a heat shrinkable film, a copper foil adhesive tape, a polyimide adhesive tape and a box. Shielding between a shielding uncovering part and a connector is realized by using a metal cover such as a copper cloth, so that 360 degree sealed overlapping connection between the shielding layer and the electrical connector is realized; The shielding integrity of the whole signal transmission path is realized by coveringthe gap between the connector and the chassis and between the chassis and the chassis with a plastic and sticky metal cover such as copper foil adhesive tape. The cable connection according to the invention can remarkably reduce the electromagnetic leakage between the cable and the connector and between the connector and the box, thereby realizing comprehensive and continuous electromagnetic shielding of the entire signal transmission path, and solving the problem that the traditional shielding by means of a shielding card or the tail cover needs extra weight and mounting space.

Description

technical field [0001] The present invention relates to satellite cable signal transmission, in particular to a cable connection with shielding continuity. Background technique [0002] As an important part of electronic signal transmission, transmission cables and electrical connectors should have good transmission characteristics and electromagnetic compatibility. As the signal transmission path, electrical connectors and shielded cables should form a completely closed Faraday cage to ensure the continuity of electromagnetic shielding, thereby enhancing shielding effectiveness. The shielding continuity mainly depends on the terminal connection of the shielded cable, and the shielding layer and the rear shell of the electrical connector form a 360° closed lap to avoid electromagnetic leakage. The current termination methods mainly include the following types: [0003] (1) using shielding card [0004] Lay the cables to the wiring points, compare the wiring length, and le...
