Let me clarify my question, if two conductors of different materials placed in contact with each other and one material is heated, the heat energy is transferred to the other material by conduction, as a result the temperature of sceond material rises.
.
Now let us take our query, as heater coil gets heated the contact wires must also get heated due to the heat conduction from the heater coil. But this is not happening in the real case. (In essence the temperature of the contact wire almost remains unchanged) What is the reason?
Please consider this question in a very fundamental manner. For example if we connect a small piece of nicrome coil to a lead acid battery via a copper wire without any insulation the same thing is happening.

The nichrome wire is hot because of the electrical power that's being supplied to it. The connection wire is only getting conducted heat that is conducted, radiated and convected away.
