The heat of the high-current connector is the most important design consideration, we all know that U = I ^ 2RT, high-current connector fever is the most important design consideration, this power consumption is mainly into the form of heat distributing constant current I, the power consumption into and distributed in the form of heat, reduce the resistance is the focus of the design, the resistance R = Rc + Rw. how to reduce the resistance R:

A. Contact surface roughness of the surface of the pin jack, pin jack contact surface roughness, roughness surfaces, the effective contact area corresponding to the contact resistance is low, and the other the roughness good surface electrical degrees effect has been achieved, the hot plug of the risk is low.

B. The conductivity of the material. This factor determines the resistance Rw of the material itself, the resistance will reduce the power output.

C. Reliable elasticity of the material of the pin jack connection. Life requirements, it is necessary to ensure reliable contact with many times the situation, and permit use of a reliable contact, many times the situation which the elasticity of the material put forward high requirements to ensure reliable elastic contact.

D. Materials processing and economy. The processing efficiency of the copper alloys are very different.
