Aviation Plug Material Should Choose Environmental Protection Material

Aviation Plug Material Should Choose Environmental Protection Material

The reflow welding technology is used for electrical connectors. The temperature of this welding technology is higher than that of fluctuating welding, which means that the material of electrical connectors needs to be able to resist significantly higher temperature. Usually, the heating deformation temperature of general materials is higher than 250 C. In order to meet the reflow welding technology, PA6 and PBT can not meet the requirement that the heating deformation temperature of materials is higher than 250 C, so they need to be replaced by high temperature resistant materials. This is the case.

Considering the use of harness environment, harness sheath is needed in extreme environment, such as high temperature, extreme cold, acid-base corrosion, oil pollution and wear.

It can be divided into PVC tube, PU tube, bellows, fiber net, foam tube and so on. The size of the pipe is marked by its diameter. The bigger the diameter, the thicker the pipe.

PVC pipes are widely used, mainly to prevent the wiring harness from spreading, smooth surface, hard in winter, brittle and fragile for a long time, there are openings and closures. Most of the colours are black.

PU pipe, smooth surface, soft material, long service life, there are openings and closures, the color is mostly black.

Fiber network management, the main role is to prevent the harness from spreading, relatively more flexible.

Bellows, mostly coarser wiring harness, oil resistance, acid and alkali resistance, etc.
