GPH90 ºcopper Tube Terminals

ST Insulated Terminals in electrical maintenance terminal as a connector, is an important component of the electric power industry, plays an irreplaceable important role.Engineers and technicians are usually first and check from the interface, it from the beginning of the terminal, terminal design is particularly important.Product design is a product, material, structure, plating, certification, mold, and terminal manufacturing integrated design, is no exception.
1. Product standards are guiding principles on average, and almost all the factors on the basis of this, we start with UL and CSA standard design terminal shall prevail, but in some electrical parameters can also be based on other standard as the foundation, including the high/low temperature test station.
2. The choice of the insulation terminal material directly affect the entire product performance, is the key to the design, plastic materials: if it is to the UL94, under the condition of V - 0 flame retardant according to the design will carefully examine and verify the technical parameters can meet the standards of products, because of the impact resistance partial pressure and resistance to aging test whether can have a home of material actual sex table in the aspect of hardware mainly is TP tablet material choice is particularly important, because the pressure both meet the conductivity of the (current) must have a degree of elasticity that in selecting material for our engineers brought difficulties, and it is the pursuit of tide of elastic element which is connected equipment manufacturers of materials, many manufacturer of metal material is the efforts to directly affect the conductivity temperature increases and the contact resistance, elasticity and bad material chemical composition, and modulus and the hardness and tensile strength, modulus of materials, mechanical calculation and selection of the fourth strength theory formula.
The electrical conductivity of the material, the smaller temperature rise is larger contact resistance, and quadratic curve of low contact resistance of plug power relations, mainly divides into: contact resistance pressure, membrane resistance and volume resistance (the resistance of the conductor itself).
Which film layer accounts for 70-80% of total resistance, resistance is the main factor affecting the service life of connected devices, should be given sufficient attention, gold-plated silver to a terminal to although than the conductivity of the silver than Huang Jingao, but its good chemical stability, resistance caused by no gold film layer is far greater than gold plated, so to understand the relationship between the above have guiding significance on the material we choose is the precondition of product design.
