Abstract

An electrical connection device and a terminal are provided. The electrical connection device includes first and second connectors. The first connector includes an insulating body and a plurality of blade-type terminals. The insulating body has a base portion and two ear portions, an inner wall surface of the ear portion has a first guide groove which is perpendicular to the base portion and a second guide groove which is parallel to the base portion. The second connector includes an insulating housing and a plurality of elastic terminals. The insulating housing has a mating portion and a protruding rail, the mating portion has a plurality of terminal grooves respectively provided with the elastic terminals. When the connectors are mated, each contact portion can contact the guide portion of the corresponding elastic terminal and then contact the contact portion of the corresponding elastic terminal to prevent the elastic terminal from being damaged.

First claim
