Dimension cladding, shield sheet are coated on around the core wire with the state parallel with the core wire, twine glass fiber tape spiral
It is wound in the helicla flute in the outside of the shield sheet, single armed heat-shrink tube is wrapped in the shield sheet, not only make line
The shielding line of beam can effectively shield the interference of electromagnetic wave or outer signals, and in core material connection, save conducting wire, and
Reduce process time.
Specific embodiment
The present invention is described in further detail below, to enable those skilled in the art's refer to the instruction text being capable of evidence
To implement.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or combinations thereof.
The present invention provides a kind of new engine beam shield line manufacturing process, step includes:
1) both ends of more core wires are crimped on connector spaced apart respectively, can be thus greatly simplified
The work of linear measure longimetry and crimping, and improve speed, the core wire connected in the middle part of connector is most short, towards the both ends of connector by
Gradual change is long, and core wire is connector shell and stainless steel loose, which there is resin component to constitute in its natural state
The shielding shell that component is constituted, connector are electrically connected with conducting wire, and the connecting hole of multiple lines and multiple rows is arranged on the connector；
2) by the silver-colored covering thermoplastic fibre cladding of adjacent core wire, the silver covering thermoplastic fibre diameter is 0.02~
With silver-colored covering thermoplastic fibre cladding, silver fiber has good for 0.05cm, adjacent longitudinal core wire and lateral core wire
Electric conductivity, this performance be general conductive metal several times so that hundreds times, the anti-radiation basic principle of electric conductivity.Use silver fiber
