Abstract
The present invention relates to a kind of processing method of the screen layer of shielding line.Including Step 1: all single-core shielding line one end divest external insulation layer, screen layer turns to external insulation layer outside；Step 2: all single-core shielding lines are gathered for wire harness, and the screen layer that turns up of all shielding lines gathers together, and is turned up screen layer with tying coil winding；Step 3: warding off tin at the screen layer tying coil that turns up, and earth lead is welded at tying coil simultaneously；Step 4: heat-shrinkable T bush is set with the screen layer that turns up so that heat-shrinkable T bush wraps the whole screen layer that turns up.The assembly method solves：Assembling difficult point that have acute angle inside cable curve type rear attachment, that assembly space is narrow and small.There is larger space with cable clip, reduce extruding and wear in the core of a cable that the assembly method makes, improve product reliability.
Description
Technical field
The invention belongs to process class, applied to Military aeronautic products, the product for civilian use.
Background technology
Screen layer processing method foundation used by traditional cable makes《IPC/WHMA-A-620XXX》Screen layer is carried out
Processing, and wire is welded with every shielding line screen layer, screen layer weld set heat-shrinkable T bush shrinks, the screen layer after processing
Solder joint is larger.Acute angle in cable curve type rear attachment be present, and space is more narrow and small, is connected two-by-two using every cored wire screen layer
Screen layer processing method, the wire harness solder joint of boundling is larger, and wire harness is thicker, easily with producing extruding and abrasion at rear attachment inside corners.
In order to reduce the abrasion of wire harness, ensure product quality, so as to be made by the technique for changing curved formula rear attachment cable
Method come reduce screen layer solder joint, reduce beam diameter.
The content of the invention
Goal of the invention：The purpose of the present invention is to reduce extruding, the assembling of abrasion of wire harness inside curved formula rear attachment cable
Method.
Technical scheme：This programme is directed to the characteristics of curved formula rear attachment, is subtracted by changing the processing method of beam shield layer
Few beam diameter.The screen layer of every shielding line is turned up, all cored wires tighten fixation with tying coil, are carried out after tying up bunchy
Ward off tin.Heat-shrinkable T bush is covered at screen layer processing and shrinks protection.
A kind of processing method of the screen layer of shielding line, the wire harness of more single-core shielding lines, wherein every list are specifically provided
Core shielding line comprises at least external insulation layer, screen layer and cored wire；
Step 1: all single-core shielding line one end divest external insulation layer, external insulation layer is turned to outside screen layer；
Step 2: all single-core shielding lines are gathered for wire harness, and the screen layer that turns up of all shielding lines gathers together,
And wind the screen layer that turns up with tying coil；
Step 3: warding off tin at the screen layer tying coil that turns up, and earth lead is welded at tying coil simultaneously；
Step 4: heat-shrinkable T bush is set with the screen layer that turns up so that heat-shrinkable T bush wraps the whole screen layer that turns up.
Wherein, in step 1, also to check the screen layer after turning up whether there is and form short circuit with cored wire.
Beneficial effect：
Cable after to improvement measures, and the bundle conductor inside cable clip has larger sky with multi-plug cable folder
Gap, reduce extruding, the degree of wear；The degree for reducing every cored wire screen layer phase mutual friction after bunchy is tied up, after reduction processing
Screen layer solder joint.Reduce the beam diameter after boundling, screen layer has larger space with rear attachment.
Brief description of the drawings
Fig. 1 is the structural representation of shielding line；
Fig. 2 is to turn to schematic diagram on external insulation layer outside screen layer；
Fig. 3 be after wire boundling after the processing of more screen layers with silver-gilt copper wire colligation, ward off the schematic diagram that tin handles；
Wherein：1- external insulation layers, 2- screen layers, 3- cored wires.
Embodiment
A kind of processing method of the screen layer of shielding line, the wire harness of more single-core shielding lines, wherein every single screen are provided
Cover line and comprise at least external insulation layer 1, screen layer 2 and cored wire 3；
Step 1: all single-core shielding line one end divest external insulation layer 1, external insulation layer is turned to outside screen layer 2；
Step 2: all single-core shielding lines are gathered for wire harness, and the screen layer that turns up of all shielding lines gathers together,
And wind the screen layer that turns up with tying coil；
Step 3: warding off tin at the screen layer tying coil that turns up, and earth lead is welded at tying coil simultaneously；
Step 4: heat-shrinkable T bush is set with the screen layer that turns up so that heat-shrinkable T bush wraps the whole screen layer that turns up.
Wherein, in step 1, also to check the screen layer after turning up whether there is and form short circuit with cored wire.
Claims (2)
1. a kind of processing method of the screen layer of shielding line, the wire harness of more single-core shielding lines, wherein every single-core shielding line is extremely
Include external insulation layer, screen layer and cored wire less；
Step 1: all single-core shielding line one end divest external insulation layer, external insulation layer is turned to outside screen layer；
Step 2: all single-core shielding lines are gathered for wire harness, and the screen layer that turns up of all shielding lines gathers together, and is used in combination
Tying coil winds the screen layer that turns up；
Step 3: warding off tin at the screen layer tying coil that turns up, and earth lead is welded at tying coil simultaneously；
Step 4: heat-shrinkable T bush is set with the screen layer that turns up so that heat-shrinkable T bush wraps the whole screen layer that turns up.
A kind of 2. processing method of the screen layer of shielding line as claimed in claim 1, it is characterised in that：In step 1, also
Check the screen layer after turning up whether there is and form short circuit with cored wire.
