Definitions
- This application relates to a terminal with memory function.
- the memory contact section 3 has a cylindrical structure, and the number of contact claws 31 is greater than or equal to 3 (such as 8).
- the cross-sectional area of the plurality of contact claws 31 can be large or small Alternate settings.
- the size of the cross-sectional area of the contact claw 31 is related to the elasticity of the contact claw 31 itself. The larger the cross-sectional area, the better the elasticity of the contact claw 31.
- the size of the cross-sectional area of the claws 31 is arranged alternately, so that the elastic force of the contact claws can be correspondingly and evenly distributed on the mating terminal.
- Table 1 Effects of different coating materials on the insertion and withdrawal times and corrosion resistance of terminals with memory function
- the coating material is gold, silver, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, graphene silver, and silver-gold-zirconium alloy
- the experimental results exceed the standard value and the performance is relatively stable.
- the coating material is gold, silver, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, graphene silver, and silver-gold-zirconium alloy
- the coating material is gold, silver, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, graphene silver and silver-gold-zirconium alloy.
- the temperature rise test in the following table 2 is to pass the same current to the terminal with memory function after plugging in and to the terminal with the plug-in terminal, and to test that the terminal with memory function before power-on and after temperature stabilization is the same in a closed environment. location temperature, and do the difference to take the absolute value. In this embodiment, a temperature rise greater than 50K is considered unqualified.
- the vacuum plating method is to deposit various metal and non-metal films on the surface of plastic parts by distillation or sputtering under vacuum conditions.
- the length of the inner conductive contact strip 33 and the length of the outer memory strip 34 may be the same, and the thickness of the inner conductive contact strip 33 is less than or equal to the thickness of the outer memory strip 34 .
