"Let's see what materials are used for waterproof connectors"

There are many manufacturers of waterproof connectors in the market. Most of the materials used are basically the same in name, but only a part of the materials are really dense, and some of the materials used are special. As we all know, the quality of the materials determines the service life, safety performance and environmental protection performance of the products. Let Electric Bee Optimum Engineer Technology lead everyone to recognize the standard materials commonly used in the production of waterproof connectors and its advantages!

The first: shell material

Nylon (English name Polyamide (PA): currently divided into two kinds of "nylon 6 and nylon 66" is a thermoplastic resin containing repeating amide groups-[NHCO]-on the molecular backbone.

Advantages: heat resistance, low friction coefficient, wear resistance, self-lubrication, shock absorption and noise reduction, oil resistance, weak acid resistance, alkali resistance and general solvents, good electrical insulation, self-extinguishing, non-toxic, odorless, good weather resistance.

PVC: chemical name polyvinyl chloride

Advantages: folding resistance, light resistance, water resistance, oxidation resistance

The second: hardware material

gold plated copper:

Advantage: to ensure that the copper surface does not fall off

The third: O-type waterproof ring

Rubber: a double insulated wire

Advantages: good elasticity, cold resistance, high temperature resistance, oil resistance, UV resistance, good flexibility, high strength

The fourth: sealing gasket

Silica gel: can be divided into organic silica gel and inorganic silica gel two categories

Advantages: heat resistance, cold resistance, dielectric resistance, ozone resistance and atmospheric aging resistance
