Description

Shielded wiring module

Technical Field

The present utility model relates to a shielded wiring module.

Background

When wiring a wire, it is generally necessary to remove an insulating coating, a shielding layer, or the like of the wire to expose the core. After the connection of the wire cores is completed, insulation measures and shielding measures are required to be applied to the joint, namely the exposed wire cores, so as to avoid distortion and attenuation of signals.

At present, butt joint between different shielding wires on an aircraft is mainly carried out through shielding heat-shrinkable tubes for shielding welding. The shielding heat shrinkage pipe sequentially comprises an insulating pipe body, a shielding layer and a protective layer from inside to outside, wherein the insulating pipe body is provided with a pipe cavity for wrapping a wire, a cable and the like, the shielding layer is coated on the periphery of the insulating pipe body, the protective layer is coated on the periphery of the shielding layer, and the insulating pipe body, the shielding layer and the protective layer are tightly attached to form an integral structure. And (3) performing shielding welding on the connector of the lead through the shielding heat shrink tube, firstly sleeving the shielding heat shrink tube on the connector, and then heating the shielding heat shrink tube to shrink the shielding heat shrink tube.

The shielding of the wire connector can be realized by shielding welding through the shielding heat shrink tube, but only the butt joint of a small amount of wires is applicable.

In interfacing a plurality of wires, a feedback module is typically used for interfacing. However, since the feedback module itself has no shielding effect, it is necessary to draw out the shielding lead to the nearby ground module (see fig. 6), but only a non-360 degree shielding can be achieved. Therefore, a device with good shielding effect, which can be conveniently installed, is specially designed to perform shielding butt joint of a plurality of wires. This approach is undesirable in terms of manufacturability and cost, and there is room for further improvement.
