Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector mounted to a circuit board.

Designers of electronic circuits typically focus on two basic circuit components, the logic portion and the power supply portion. When designing a logic circuit, because the current flowing in the logic circuit is low, the designer typically does not consider any changes in the electrical properties (such as the impedance of the circuit components) due to state changes (eg, temperature). However, the high current flow will easily cause the power circuit to change its electrical properties under the Joule effect. Therefore, in order to enable the power connector to pass a high current, the resistance of the conductive terminal of the power connector must be minimized, thereby reducing the heat generated by the Joule effect; at the same time, the heat dissipation area of the conductive terminal should be as large as possible, thereby causing Joule The heat generated by the effect is released as quickly as possible.
