Abstract:
1. An electric connection terminal configured to come into contact with an object to be connected to, by being elastically deformed in a direction orthogonal to an insertion direction of the object to be connected to, the electric connection terminal comprising: a contact portion formed in a forked shape and including first and second junction portions, each at tip portions, to come into contact with the object to be connected to, provided at intervals in the insertion direction of the object to be connected to, in which upon the object to be connected to being inserted, the first junction portion comes into contact with the object to be connected to prior to the second junction portion; a fixed portion configured to be fixed to an object to be attached to; an elastic piece portion formed between the contact portion and the fixed portion; a first fulcrum portion provided to the elastic piece portion at a position close to the fixed portion; and a second fulcrum portion provided to the elastic piece portion at a position close to the contact portion, wherein the second fulcrum portion, the first junction portion, the second junction portion, and the first fulcrum portion are disposed in that order in the insertion direction of the object to be connected to, wherein the second fulcrum portion, the first junction portion, the second junction portion, and the first fulcrum portion are formed so that distance from the second fulcrum portion to the second junction portion is longer than distance from the second fulcrum portion to the first junction portion, wherein the first junction portion is disposed closer to the second fulcrum portion side than an intermediate point between the first and second fulcrum portions in the insertion direction of the object to be connected to, and the second junction portion is disposed closer to the first fulcrum portion side than the intermediate point, wherein the second fulcrum portion is disposed at a position that is farther from the object to be connected to than the first fulcrum portion in the direction orthogonal to the insertion direction of the object to be connected to, and wherein the second junction portion is formed so that, upon the first junction portion being pressed in the opposite direction of a direction of contact with the object to be connected to, the second junction portion is displaced relatively in the direction of contact with the object to be connected to as compared to the first junction portion by the elastic piece portion being elastically deformed with the first fulcrum portion as a fulcrum, and the first junction portion is formed so that, upon the second junction portion being pressed in the opposite direction of the direction of contact with the object to be connected to, the first junction portion is displaced relatively in the direction of contact with the object to be connected to as compared to the second junction portion by the elastic piece portion being elastically deformed with the second fulcrum portion as a fulcrum.
