2 standard terminal section 10 of the mechanical properties test, test and plug terminal 11 insertion - pull out the standard terminals used in the test material should be non-plated brass alloy C26000 equal to 2.2 in the first Standard terminal 12 of the temperature and thermal cycling tests used should be tin plate or corrosion-resistant steel, according to Rockwell 30T hardness standards, Rockwell hardness of 68 ± 5. Exception: Only if the female terminals connected to a copper alloy male terminal, military signal line manufacturers, then when you need to use a standard terminal C26000 copper alloy tested. Standard terminal 2.3 by Rockwell 30T hardness standard, made of brass hardness of 62 ± two terminals with two consecutive numbers 7 5.2.1 distinguish the individual elements, the odd number should be less than an even number, military signal line manufacturers address, such as a single intermediate element and 2.5.2.2 use numbers to distinguish each terminal, preferably by increasing the number of natural sequence of numbers. For example: 3,4,5, etc. Each terminal is greater than the selected intermediate digital numbers on both sides of the terminals, and the terminals should be close to the start flag at the smaller numbers, e.g., as an intermediate element on both sides of the terminals 1 and 2 with each terminal 3,4,5 and other digital mark. Both sides terminals and two intermediate terminals 5.2.3 If several similar elements are combined into a group, specializing in military signal line terminals can be connected to various components of the following methods flags: a. 5.2.1 Digital preceded by letters and by regulation 5.2.2 to distinguish between each of the terminals on both sides of the terminal and intermediate, eg: U, V, W flag three-phase AC system each phase terminal equipment; many production of metal materials, manufacturers are these efforts, conductivity and temperature directly affect contact resistance, chemical elements and material quality of elasticity, elastic modulus, hardness, tensile strength related to the elastic modulus of the material mechanics choice The fourth strength theory formula to calculate. The greater the conductivity of the material, the more lower contact resistance small temperature rise, and plug the power relations and the contact resistance to a quadratic curve, the contact resistance is divided into: compression resistance, the film resistance, volume resistance (resistance of the conductor itself) . 70 to 80% of the total resistance of the resistor layer is the main factor affecting the life of the connector, should be given full attention, military signal line, with regard to the terminals to more than Gold and silver plating, although conductivity than gold and silver higher But there is no golden good chemical stability, resistance film caused far greater than gold, so find out the relationship between the above there is the choice of materials for our guidance, it is a prerequisite for product design.
