Embodiment Construction

[0018] Provide a method for processing the shielding layer of shielded wires, a wire harness of multiple single-core shielded wires, wherein each single-core shielded wire at least includes an outer insulating layer 1, a shielding layer 2 and a core wire 3;

[0019] Step 1. Strip off the outer insulation layer 1 at one end of all single-core shielded wires, and turn the shielding layer 2 outward to the outer insulation layer;

[0020] Step 2. Gather all single-core shielded wires into a wire harness, and gather the turned-out shielding layers of all shielded wires together, and wrap the turned-out shielding layer with a binding coil;

[0021] Step 3, tinning the binding coil of the outward shielding layer, and welding the grounding wire at the binding coil at the same time;

[0022] Step 4: Put a heat-shrinkable sleeve on the turned-out shielding layer so that the heat-shrinkable sleeve wraps the entire turned-out shielding layer.

[0023] Among them, in step 1, it is also ne...

Abstract

The invention relates to a processing method of a shielding layer of a shielding wire. The method comprises steps that step 1, an outer insulation layer at one end of each single core shielding wire is stripped, and the shielding layer is overturned to the outer insulation layer; step 2, all the single core shielding wires are gathered together to be a wire harness, all the overturned shielding layers of all the shielding wires are gathered together, and a binding coil is utilized to wind the overturned shielding layers; step 3, the coil binding portion of the overturned shielding layers is coated with tin, and the coil binding portion is welded with a ground lead; and step 4, a thermal shrinkage casing is sleeved at the overturned shielding layers, and the whole overturned shielding layers are covered by the thermal shrinkage casing. The method is advantaged in that assembling difficulties including an acute angle in a cable bending type rear accessory and small assembling space are solved, a cable harness and a cable clamp manufactured through the method have relatively large gaps, extrusion and wear are reduced, and product reliability is improved.

Description

technical field [0001] The invention belongs to the category of technological methods and is applied to military aviation products and civilian products. Background technique [0002] The shielding layer processing method used in traditional cable production is based on "IPC / WHMA-A-620XXX" to process the shielding layer, and a wire is welded to the shielding layer of each shielding wire, and the heat shrinkable sleeve is shrunk at the welding place of the shielding layer. The rear shielding layer has larger solder joints. There are sharp angles in the rear attachment of the cable bend, and the space is relatively narrow. The shielding layer of each core wire is connected in pairs. Extrusion and wear occur. [0003] In order to reduce the wear and tear of the wire harness and ensure the product quality, the solder joints of the shielding layer and the diameter of the wire harness are reduced by changing the manufacturing method of the bent rear accessory cable.
