Description

Terminal and electrical connection assembly

Technical Field

The present utility model relates to a terminal and an electrical connection assembly including the same.

Background

In the related art, it is sometimes necessary to simultaneously mount a plurality of terminals on a circuit board, and a plurality of mating plugs are adapted to be respectively inserted into the plurality of terminals to be respectively electrically contacted with the plurality of terminals. In order to be able to insert a plurality of mating plugs into a plurality of terminals simultaneously, the mounting position error of each terminal should be small or zero, otherwise a plurality of mating plugs cannot be inserted into a plurality of terminals simultaneously.
