Description
Technical field
The present invention relates to bunch of cables shielding layer grounding processing methods on a kind of bullet, belong to circuit assembly manufacturing technology field.
Background technique
In missile armament electrical system, due to the demand of the anti-electromagnetic interference of system, shielded layer is widely used, bullet is powered on
Cable Shu Jinhang protection, can effectively completely cut off influence of the external electromagnetic interference to harness internal signal.It must be to screen in harness production
It covers a layer end to be handled, prevents the wire breakage of shielded layer from puncturing the exhausted of inner lead as fifth wheel or wire
Edge layer, while also needing for shielded layer and earth lead to be attached, reinforce the anti-tampering effect of shielded layer.Shielding layer grounding processing
The reliability for directly influencing cable on bullet becomes the important ring in bunch of cables production.
Traditional shielding layer grounding processing method is to draw an osculum in shielded layer side, and conducting wire is pulled out from osculum,
The empty shielded layer that will be left behind is straightened wring after upper tin, be attached with earth lead.(it is greater than 3 when shielded wire is more in harness
Root) when, using conventional process shielded layer, empty shielded layer diameter is much larger than earth lead wire core diameter, and it is unreliable to connect,
Tie point fracture easily occurs when missile flight vibrates, and the wire presence of shielded layer end punctures the hidden of wire insulation
Suffer from.
Therefore, using traditional shielding layer grounding processing method, it is low that there are reliabilities, there is the shortcomings that conducting wire breakage hidden danger.
