There are many manufacturers of waterproof electrical connectors on the market. Most of the materials used are basically the same, but the material density is only a part of the material density. Some materials are also used. The quality of the materials is determined by the quality of the products. Life, safety and environmental performance, let me lead you to understand the standard materials commonly used in the production of waterproof connectors and its advantages!
The first type: shell material
Nylon (English name Polyamide (PA): currently divided into two types of “nylon 6 and nylon 66” is a thermoplastic resin containing a repeating amide group – [NHCO] in the main chain of the molecule.
Advantages: heat resistance, low friction coefficient, abrasion resistance, self-lubricating, shock absorption and sound absorbing, oil resistance, weak acid resistance, alkali resistance and general solvent, good electrical insulation, self-extinguishing, non-toxic, odorless, Good weather resistance.
PVC: chemical name polyvinyl chloride
Advantages: resistance to folding, light, water, oxidation
Second: hardware material
Copper plated gold:
Advantages: ensure that the copper surface does not fall off
Third: O-type waterproof ring
Rubber: a double insulated wire
Advantages: good elasticity, cold resistance, high temperature resistance, oil resistance, UV resistance, good flexibility and high strength
Fourth: sealing gasket
Silica gel: can be divided into two major categories: organic silica gel and inorganic silica gel
Advantages: heat resistance, cold resistance, dielectric properties, ozone resistance and weather resistance
