Embodiment Construction

[0016] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the description.

[0017] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0018] The present invention provides a new manufacturing process for shielded wires of engine harnesses, the steps of which include:

[0019] 1) The two ends of multiple core wires are respectively crimped on the connector at a certain distance, which can greatly simplify the work of length measurement and crimping, and increase the speed. The core wire connecting the middle part of the connector is the shortest. The two ends of the connector gradually become longer, and the core wire is loose in the natural state. The connector has a connector shell made of resin parts and a shielding shell made of stainless steel parts. T...

Abstract

The invention provides a manufacturing technology of a novel engine cable harness shielded wire. The manufacturing technology comprises the followings steps: (1) welding two ends of a plurality of core wires onto connectors at certain intervals through pressure respectively; (2) coating the adjacent core wires with silver cladding thermoplastic fiber; (3) coating shielding sheets around the core wires in parallel to the core wires, wherein the shielding sheets are in the shapes of long stripes along the longitudinal directions of the core wires, and the shielding sheets are waved by copper fibers in a criss-cross manner and are in a screw shape on the outer side; (4) spirally winding a glass fiber belt inside a spiral groove on the outer side of the shielding sheets; and (5) coating single-arm heat shrink tubes on the shielding sheets, wherein the baked single-arm heat shrink tubes use the shielding sheets so that the core wires of the shielded wire are electrically connected with any core wire of other shielded wires. According to the shielded wire, the interference of electromagnetic waves or external signals can be effectively shielded, wires are saved in the connection of core materials, few metal nets are sheared, and the processing time is reduced.

Description

technical field [0001] The invention relates to a manufacturing process of a novel engine wiring harness shielding wire Background technique [0002] A shielded wire harness is used due to the necessity of electromagnetic shielding for performing protection from electromagnetic noise, leakage prevention of electromagnetic noise, and the like. A shielded wire harness is manufactured by covering the wire harness with an electromagnetic shielding material. With the development of industry, more and more occasions need to use electricity, and a large number of cables are needed to transmit electricity from power plants or power stations to electric fields. At present, most cables are copper wires or other conductive wires. The metal is covered with a layer of insulating material. In some special occasions, communication stations, etc., due to strong electromagnetic interference, ordinary cables cannot shield electromagnetic waves or other external signals, making it easy for ca...
