Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] Please refer to figure 1 , the wire in the preferred embodiment of the present invention includes a conductor core 10 and a cladding layer 20 wrapped around the outer periphery of the conductor core 10 .

[0022] The conductor core 10 is formed by twisting a plurality of conductor elements 11 with each other. Preferably, the conductor core 10 includes seven conductor elements 11, and the diameter of each conductor element 11 is between 0.294mm and 0.306mm; or the diameter of each conductor element 11 is between 0.417mm and 0.443mm. In this embodiment, the number of conductor cores 10 is one.

[0023] The cladding layer 20 includes a first insulating layer 21 wound on the conductor core 10, a second insulating layer 23 wrapped around the fir...

Abstract

The invention relates to a cladding layer of a lead, and a lead provided with the same. The cladding layer is clad on the circumference of a lead core of the lead, and comprises a first insulating layer wound on a conductor core, a second insulating layer wrapped on the first insulating layer, a shielding layer wrapped on the second insulating layer and a protective layer wrapped on the circumference of the shielding layer; the first insulating layer adopts a banded structure formed by mica; the second insulating layer is formed by weaving glass fibers; the shielding layer is formed by weaving nickel wires; and the protective layer is formed by weaving glass fibers. In the lead, the cladding layer is composed of the first insulating layer, the second insulating layer, the shielding layer and the protective layer, the first insulating layer is wound with a mica tape, the second insulating layer adopts the reticular glass fiber, the shielding layer adopts the netted nickel wires, and the protective layer adopts the reticular glass fiber, so that the temperature tolerance of the lead is effectively ensured, and the purpose of non-aging of the lead used in the high-temperature environment is further achieved.

Description

technical field [0001] The invention relates to the field of electric signal transmission, in particular to a coating layer of a wire and a wire with the coating layer. Background technique [0002] In the field of high-performance airframe wires, such as those used in commercial and military aircraft, the wires must meet stringent performance levels, including thermomechanical properties. Generally speaking, commercial and military aircraft often work in high-temperature environments, and ordinary wires used in electrical equipment and instruments are prone to aging in high-temperature environments, which affects the conductivity and service life of the wires. The maximum operating temperature in the high-temperature zone of the engine is 450°C, and there is no mature product of high-temperature wires that meets this condition in China. Contents of the invention [0003] The purpose of the present invention is to provide a high temperature resistant wire to solve the tec...
