Precautions for manufacturing copper tube terminals

copper tube terminal production and manufacturing precautions in the scientific research of copper tube terminal quality assurance problems are will take into account the various natural environment it encountered, then, in the design of the terminal will fully consider all raw materials including metal composite materials and raw materials. The raw material will harm the quality of wiring Terminals, this problem is all the design staff in the design of copper terminal to take into account. The quality characteristics of the terminal insulation layer shell are as high as the metal structure, the vast majority of the insulation layer shell is made of PA66, PC, PP and other plastic. No matter which kind of raw material, the shell is stipulated to achieve the corresponding fire grade, temperature resistance, environmental protection characteristics, dielectric strength and impact toughness.

The key of the brass terminals metal material components of the electrical conductivity, screws and clamping piece, in which the key is the conductivity of the copper content is how much, in the national standard "household and similar use plug socket (GB2099) and the fixed device of the electrical switches for household and similar purposes" (GB16915), clearly stipulates composition of copper is 58% less. Copper has very good metal material laser cutting processing characteristics and high corrosion resistance characteristics; Copper is only second to silver in conductivity. Therefore, copper is particularly suitable for the composition of electrical and mechanical connection components such as terminals. Copper metal products and copper wire have basically the same linear expansion coefficient, to prevent the temperature fluctuation caused by different levels of thermal deformation, so it can prevent the Copper Tube Terminals caused by mechanical equipment stress, prevent the resulting loosening of the connection. Screws and clamping pieces of copper alloy is commonly used in raw materials, or surface plating process antirust treatment of steel raw materials, the key is to have the corrosion features and plenty of impact toughness, under normal circumstances do not apply an surface plating process antirust treatment of steel raw materials, it can prevent the steel metal products and copper wires in a damp condition of rechargeable batteries, To prevent the occurrence of unreliable electrical connection and screw rust caused by electrical erosion. The surface of the general steel component must be plated with nickel, which can have a certain anti-corrosion effect.
